This original permit covered COPADand tenant operations at GYR. The MSGP-2000 expired in 2005 and wasadministratively continued in Arizona until February 1, 2011 when the AZPDES MSGP-2010 became effective.Stormwater discharges at Phoenix Airports are currently covered under the MSGP-2010.GYR is covered under the MSGP-2010 Sector S. The stormwater pollution preventionprogram at GYR includes airport tenants covered by MSGP-2010 Sector S that conductindustrial activities at the airport as co-permittees. In addition to co-permittees, COPADrequires tenants and operators at the airport not covered under the MSGP-2010, butconducting activities with the potential to cause stormwater pollution to comply withthe SWPPP. For the purposes of compliance with this SWPPP, “co-permittee” refers to4

all tenants, COPAD divisions and operators who conduct activities that may influencestormwater quality. COPAD submitted Notices of Intent (NOIs) to seek coverage underMSGP-2010 (for COPAD facilities and the co-permittees) by the permit deadline of May31, 2011. Copies of these NOIs are on the Stormwater Database and a blank NOI isincluded as Attachment 2, as required by MSGP-2010 Part 5.4.1.3 Site BackgroundCo-permittees perform a variety of industrial activities covered under the MSGP-2010Sector S that have the potential to discharge pollutants to the stormwater drainagesystem. PECM manages the MSGP stormwater pollution prevention program,assuming the roles of both program administrator and co-permittee with participatingairport tenants and service providers.As a condition of tenant lease agreements and obtaining access to do business, tenantsand other service providers at GYR are required to comply with applicableenvironmental rules and regulations, including securing coverage under the MSGP-2010, if applicable. Entities potentially subject to the MSGP-2010 at GYR include tenants,such as air passenger, fixed-based operators (FBOs), and other entities providing on-siteservices at GYR, such as aircraft, vehicle and equipment wash companies, and aircraft,vehicle and equipment maintenance providers. These tenants and other serviceproviders may choose to pursue coverage as co-permittees with COPAD. Companiesrequiring MSGP-2010 coverage for industrial activities that choose not to participate asco-permittees must obtain their own MSGP-2010 coverage and develop and implementtheir own SWPPPs. These individual SWPPPs must be at least as stringent as thisSWPPP.There are also entities operating at GYR whose activities may impact stormwater qualitybut that are not covered by the MSGP-2010, such as private general aviation (GA)tenants. These entities are not co-permittees but must comply with the requirements ofthis SWPPP and the MSGP-2010 in order to operate at GYR.Sector-Specific RequirementsIn addition to the general requirements contained with MSGP-2010, co-permitteesconducting industrial activities at GYR are subject to the requirements of Sector S (AirTransportation). Sector-specific requirements include:• additional control measures for good housekeeping and deicing (Section 5.2 andAttachment 3.0)• additional corrective action deadline requirements (Section 6.5)• additional SWPPP requirements (various sections)Sector S also requires benchmark stormwater monitoring for airports using more than100,000 gallons per year of glycol-based fluids (MSGP-2010, Part 8.S.7, Table 8.S-1). GYRis not subject to this requirement as no deicing activities occur at this airport.5

COPAD ServicesCOPAD provides services or facilities to co-permittees specifically to minimize nonstormwaterpollution discharges as described below.Wash racks installed by COPAD for cleaning small aircraft, vehicles and equipment areprovided to minimize the impact of cleaning activities to stormwater by diverting thesenon-stormwater pollution discharges to the sanitary sewer system. Permission toconduct aircraft washing at an alternate location on the airport property is granted onlyafter an approved wash plan is on file with PECM.COPAD provides waste accumulation areas at GYR for private GA tenants to ensureproper disposal or recycling of used oil and spent solvent. COPAD provides clearlymarked containers that private GA tenants may use.Co-permittees are required to address small accidental spills. After each spilloccurrence, the responsible party is identified and, if necessary, disciplined after areview of the available facts. In addition, COPAD provides spill kits at accumulationareas and certain storage locations for general use. These spill kits are stocked with thenecessary spill response materials, such as booms and granular absorbents, and arerestocked by COPAD Operations as needed.COPAD Maintenance provides assistance to co-permittees in cleaning up fuel spills at anominal fee. More than 90% of spill cleanup operations are overseen by COPADOperations.6

Section 2 - Pollution Prevention TeamMSGP-2010, Part 5.1.1 requires COPAD to establish a PPT. The PPT is responsible forassisting the Aviation Director in developing, implementing, maintaining and revisingthe SWPPP for GYR. Co-permittees must each identify at least one employee to serve asa PPT member. The PPT member should:• Have the knowledge and experience of co-permittee operations necessary to ensurethat all aspects of facility operations are considered for the SWPPP.• Possess the local knowledge and skills to assess conditions and activities that couldimpact stormwater quality at the leasehold, to evaluate the effectiveness ofstormwater pollution CMs and to participate in routine and annual inspections.• Implement and maintain stormwater pollution CMs to prevent stormwater pollutionand take corrective actions as necessary.Primary responsibility for administering COPAD’s Stormwater Compliance Programand for maintaining and updating the SWPPP rests with PECM. Co-permittee PPTmembers are expected to:• Assist the facility manager in applying for the NOI.• Maintain and operate co-permittee-owned stormwater pollution CMs and performrepairs and maintenance as required.• Have access to an electronic or paper copy of the SWPPP, including the MSGP-2010.• Participate in the quarterly routine and annual Comprehensive Facility Inspections.• Maintain facility-specific documentation (inspection reports, maintenance records,training records, etc.) at their leasehold.Current PPT members are identified in Table 2.1.7

Section 3 - Site DescriptionThis section describes facility activities and the airport setting. The MSGP-2010 (Part5.1.2.3) also requires the SWPPP to identify the nearest receiving water(s) that mayreceive discharges from the facility.3.1 Facility ActivitiesThis section describes industrial activities conducted at GYR as required by MSGP-2010Part 5.1.2.GYR is a GA airport with private tenants. The airport is classified as a reliever airport toPhoenix Sky Harbor International Airport (PHX). The airport was built in 1943 and wasoriginally operated by the United States Navy. The airport, originally known asLitchfield Airport, was acquired by COP in 1968 and has since undergone numerousimprovements. GYR averages approximately 144,000 flight operations annually on oneexisting runway.Approximately 35 percent of the GYR facility is covered by pervious surfaces (runways,taxiways, and parking lots) and buildings. The pervious surfaces comprising theremainder of the GYR facility are concentrated in the western portion of the airport andnorthwest and southeast of the runway. Land use in the surrounding area consists ofpredominantly agricultural property. Industrial, commercial, and residentialdevelopments are located east of GYR.Industrial activities at this facility include:• Aircraft, Ground Vehicle and Equipment Maintenance (AVE)• Aircraft, Ground Vehicle and Equipment Cleaning• Aircraft, Ground Vehicle and Equipment Storage• Material Storage Areas• Airport Fuel System and Fueling Areas• Building and Grounds Maintenance3.2 General LocationGYR is located in south central Arizona, approximately two miles south of Interstate 10and Litchfield Road. The airport is situated less than a mile north of the Gila River andencompasses approximately 780 acres. Figure 1 includes the General Location Map forGYR. The map shows the location of the facility and the receiving waters within 2.5miles of the facility (MSGP-2010 Part 5.1.2.3).GYR has approximately 40 feet of relief between the northern and southern boundariesof the airport, with a gradient of 18 feet per mile sloping to the southwest. Drainagebasins connected to an underground drainage system primarily collect surface runoff.9

The receiving water for storm water discharges from GYR is Bullard Washapproximately 1,400 meters upstream of its confluence with the Gila River. Thissegment of the Gila River, from the Agua Fria to Waterman Wash, is an impaired waterlisted on the 2006/2008 303(d) Impaired Waters List. The listed parameters of concernare dichlorodiphenyltrichloroethane (DDT) Metabolites, toxaphene, and chlordane.Total Maximum Daily Loads (TMDLs) have not been completed for this impaired reachof the Gila River. GYR was built before the production and/or wide spread agriculturalapplication of these chemicals. There is no record of the use, storage or discharge ofthese contaminants from GYR. DDT, toxaphene, and chlordane have been banned fromall use in the United States since 1972, 1986, and 1988, respectively.Neither Bullard Wash nor the Gila River is an outstanding Arizona water (OAW) underA.A.C. R18-11-112.The SWPPP 2011 SWPPP identified two monitoring locations (Outfalls 1 and 2) locatedat the southwest corner of the airport near Bullard Wash.Outfall 1 drains a small undeveloped portion in the southwest corner (approx. 3 acres)with no industrial activities, material storage or potential sources of pollution other thansediment. Discharge from this area drains south via sheet flow across the perimeter roadand through the property fence to the open channel to Bullard Wash, downstream ofOutfall 2. Rip-rap has been placed along the slope between the perimeter road and thefence line to minimize erosion.Outfall 2 drains the majority of the airport (approx. 782 acres) and includes the areaswhere the industrial activities are conducted. It consists of two sub-basins with separatedischarges under low flow conditions. At high flow conditions, the two flows at Outfall2 merge at the facility and flow through four underground pipes under the propertyfence to an open, concrete-lined channel that discharges to Bullard Wash.Under the 2011 SWPPP, samples for visual assessment were collected from outside theproperty fence because most samples are collected outside of normal business hours andafter-hours access to the facility was limited. Outfall 1 was collected at the point wherethe open channel discharged to Bullard Wash and Outfall 2 from the four pipes exitingthe facility. Due to the configuration, the sample collected for Outfall 1 has beenprimarily made up of flow from Outfall 2.Arrangements have been made to allow after-hours access to the facility. The currentOutfall 1 sampling point will be eliminated. There is no location to collect a sample fromthis area since the discharge is primarily sheet flow. Furthermore, there are no industrialactivities conducted in this small drainage area and the rip-rap lined slope effectivelyreduces discharge of any sediment from the area.Two samples will be collected from Outfall 2 prior to the point where the flows merge.The sampling locations will be referred to as Outfalls 2A and 2B. The drainage basin forOutfall 2A is approximately 467 acres and includes the aircraft storage/parking areas,runway and taxiways. The drainage basin for Outfall 2B is approximately 315 acres and10

includes the hangars, buildings, vehicle parking lots, and landscaped areas. Outfall 2Balso receives overflow water from the Roosevelt Irrigation District and occasionaldischarges from decorative lakes east of the airport managed by Lockheed Martin. Thelake discharge is separately permitted.3.3 Site MapFigure 2 depicts the drainage patterns, drainage basins, and outfalls and receivingwaters. Figures 1, 2, 3, and 4 present the data required in MSGP-2010 Parts 5.1.2.3 and6.S.5.2, which are:• Size of the property in acres• Location and extent of significant structures and impervious surface• Directions of stormwater flow• Locations of stormwater conveyances (e.g., ditches, pipes and swales)• Locations of the existing structural control measures• Locations of surface water receiving the facility’s discharges or impaired waters orOAWs within 2.5 miles downstream of the facility• Locations of discharges to a regulated MS4• Locations of potential pollutant sources identified under MSGP-2010 Part 5.1.3.2• Locations where significant spills have been identified or leaks have occurred underMSGP-2010 Part 5.1.3.3• Locations of stormwater monitoring points• Locations of stormwater outfalls, each with unique identification codes, indicating theoutfalls authorized as “substantially identical” under MSGP-2010 Parts 4.2.3. and5.1.5.2 and an approximate outline of the area draining each outfall• Locations of activities that are exposed to stormwater with potential discharge fromthe facilityThere are co-permittees at GYR subject to MSGP-2010 requirements that are notincluded in Figure 1. These entities provide on-site services without having a leaseholdlocation at the airport and include wash service providers and aircraft maintenanceproviders. While they conduct Sector S specific industrial activities at GYR, the place ofbusiness is located off site.Figure 2 depicts the storm drain system and two outfall locations (discharge points) forGYR. These outfalls are located at the southwestern corner of the airport at the BullardWash.11

Section 4 - Summary of Potential PollutantSources4.1 Activities in the AreaMSGP-2010 Part 5.1.3.1 requires the SWPPP to identify each area where industrialmaterials or activities are exposed to stormwater with the potential to discharge andareas from which allowable non-stormwater discharges are released. MSGP-2010 Part8.S.5.2 requires consideration of pollutant sources in areas of airports where specificactivities take place. The following activities performed at GYR have the potential toimpact stormwater quality:• Aircraft, Ground Vehicle and Equipment Maintenance• Aircraft, Ground Vehicle and Equipment Cleaning• Aircraft, Ground Vehicle and Equipment Storage• Material Storage Areas• Airport Fuel Systems and Fueling Areas• Building and Grounds MaintenanceFigure 1 identifies the specific areas where industrial materials or activities may beexposed to stormwater. In some instances, the chemicals are stored indoors, but may betransferred or activities may be conducted outdoors utilizing the chemicals. The CMsfor each activity are provided in Attachment 3.MSGP-2010, Part 8.S.5.2 specifically requires that the potential pollutant sources fromthe following activities be identified: aircraft, runway, ground vehicle, and equipmentmaintenance and cleaning. Table 4.1 identifies the industrial activities conducted byeach co-permittee. The activities with the potential to discharge pollutants tostormwater are described below.No deicing activities occur at GYR.4.1.1 Aircraft, Ground Vehicle & Equipment MaintenanceThe majority of co-permittees maintain aircraft, equipment, and/or vehicles.Maintenance activities are performed both indoors and outdoors. At GYR, AeroTurbineperforms major overhauls, remodels interiors of large aircraft, and disassembles andsalvages aircraft for metal. Airline Training Center Arizona (ATCA) conductsmaintenance of aircraft, vehicles, and equipment. COPAD Maintenance and LuxAirconduct maintenance of vehicles and equipment.Airport maintenance activities commonly involve the use of lubricating oils, hydraulicoils, solvents, lavatory waste, used batteries, paint, and other cleaning products. Smallleaks or spills of these materials are common during maintenance activities. Copermitteesare required to report any spills and respond to these leaks and spills by13

eporting the spill and using appropriate spill response materials. All co-permitteesexcept private GA tenants (i.e., private aircraft owners) collect and dispose of their ownwaste materials. COPAD provides accumulation points for the private GA tenants useonly. The accumulation points are for the collection and recycling of used oils,transmission fluids, and disposal of waste solvents. Maintenance activities represent alow potential for significant pollutant discharge at GYR.Some co-permittees have floor drains located in maintenance areas and have certifiedthat there were no illicit connections from these drains to the storm drain system at theirleasehold. All runoff that enters floor drains is discharged to the sanitary sewer. Inaddition, some of those floor drains are routed to oil/water separators beforedischarging to the City of Goodyear sanitary sewer. There is a low potential forpollutant discharge to the storm drain system from the floor drains at these facilities.4.1.2 Aircraft, Ground Vehicle & Equipment CleaningMany co-permittees at GYR conduct aircraft washing. Wash service providers arerequired to submit a written wash plan to PECM Division identifying the washing areas,location of nearby storm drains, water retrieval/reclamation process, waterdisposal/elimination method, and wash products. Private GA tenants as well as copermitteesconduct this activity at designated wash racks. Washing at designatedoutside areas equipped with oil/water separators is only allowed with the approval ofCOPAD. The oil/water separators located at the wash area discharge to the City ofGoodyear sanitary sewer system. The Airline Training Center Arizona has a dischargepermit that allows them to discharge to a collection tank, which is then hauled off-sitefor treatment. There are two mobile WSPs with operations at GYR: AeroPanache andWest Coast Wash Station.To minimize potential for pollutant discharges from washing activities, many copermitteesuse dry-washing methods. Companies using dry wash methods are stillrequired to submit a wash plan and to protect storm drain inlets during washingactivities. Wet washing is not allowed at any other location at GYR except at thedesignated wash racks.In addition to aircraft washing, many co-permittees at GYR also conduct vehicle andequipment washing. Co-permittees conducting these activities must request and receivepermission from COPAD to conduct this activity at wash racks. Parts cleaners forequipment degreasing are located inside various hangars throughout the airport wherethey are not exposed to stormwater.In addition, parts cleaners for equipment degreasing are located inside various hangarsthroughout the airport where they are not exposed to stormwater.Washing activities represent a minimal source of non-stormwater discharges to thestorm drain system at GYR.14

4.1.3 Aircraft, Ground Vehicle & Equipment StorageTemporary storage of aircraft, vehicles, and equipment occurs at the airport. For longtermstorage of aircraft, vehicles, and equipment, co-permittees are required to drainfluids to minimize the possibility of leaking fluids. Long-term storage is consideredstorage for more than 30 days. There are designated areas for maintenance of GSEwhere equipment awaiting repair, salvage, or demolition are stored short term. Mostco-permittees also have designated areas where vehicles and equipment (i.e., tugs,lavatory carts, etc.) are stored short-term when they are not being used. In addition,some co-permittees are required to store damaged aircraft or damaged vehicles on theirproperties. These aircraft and vehicles cannot be moved due to insurance requirements.However, co-permittees are required to employ and maintain, as appropriate, controlmeasures such as drip pans for these aircraft and vehicles. At these short- and long-termstorage locations, aircraft, vehicles and equipment are stored away from storm drains orfacility drainage basins. If this is not possible, booms are placed around the aircraft,vehicles, and/or hydrocarbon-filter fabric inserts protect storm drain inlets.During rain events, residues (e.g. fuel, oil, grease) on the equipment under repair orresiduals from spills or leaks from the stored aircraft, vehicles or equipment could be asource of potential pollutants in stormwater discharges. Storage activities represent amoderate potential source of stormwater pollution for GYR.4.1.4 Material Storage AreasMany GYR co-permittees store chemicals, such as cleaning products, petroleumproducts, and paints. These co-permittees have indoor and outdoor storage areas tohouse such items. Chemicals, cleaning products, oil, and used oil are typically stored in55-gallon or smaller containers. Fuel is typically stored in above ground storage tanks(ASTs). Other materials such as cleaners, paints, and paint-related products aregenerally stored in smaller containers. Co-permittees are responsible for usingsecondary containment in material storage areas with potential exposure to stormwaterduring the course of normal operations. Since outdoor storage areas have the greatestpotential to impact stormwater, COPAD encourages cover for outside storage areas. Copermitteeswith no leasehold on airport property (such as wash service providers, orthose who maintain aircraft and equipment at satellite locations) transport chemicals,cleaning products, oil, and used oil in less than 55-gallon capacity. These smallquantities of oil and chemicals are stored inside of co-permittee vehicles and insidesecondary containment totes.Outdoor material storage areas or chemical storage areas located near doorwaysrepresent a moderate potential source of stormwater pollution for GYR.4.1.5 Airport Fuel Systems and Fueling AreasMost co-permittees conduct aircraft and/or vehicle fueling activities. Aircraft fuelingactivities are conducted only on paved surfaces such as concrete ramps or asphalt. Mostvehicle and GSE fueling is conducted on the ramp by FBO refueler.15

Fuel spills are contained promptly through use of absorbent materials or other controlmeasures. Co-permittees are required to provide spill kits and spill response plans inco-permittee-owned or leased fueling areas and COPAD Operations maintains spill kitsand spill response plans at accumulation points and certain storage locations at GYR foremergency use in containing spills. COPAD enforces Rule and Regulation 01-01, “FuelRelease and Releases of Other Regulated Substances” which was developed to complywith City of Phoenix City Code Chapter IV, Article IV, Section 4-114 “Fueling anddefueling aircraft; fueling ground service vehicles; flowage fee.”Fuel storage at GYR occurs in ASTs. Fueling is performed from transfer trucks. Fuelingservice providers are required to equip delivery trucks with spill kits and spill responseplans. Leaks from fuel transfers that are not immediately cleaned have the greatestpotential to impact stormwater. There is a significant potential impact to stormwaterduring aircraft and vehicle fueling activities and a moderate potential source ofstormwater pollution for the storage and transport of aircraft and vehicle fuel.4.1.6 Building and Grounds MaintenanceCOPAD performs apron cleaning with a mechanical street sweeper in most areas ofGYR. Outdoor apron wet washing is not allowed. Many co-permittees conduct floorwashing at their facilities and report that wash water is discharged to oil/waterseparators or directly to the City of Goodyear sanitary sewer system. Floor washingactivities do not represent a significant source of non-stormwater discharges at the stormdrain system.COPAD GYR Maintenance personnel, licensed by the Arizona Office of PestManagement (OPM), perform herbicide application at COPAD facilities. Theirchemicals are stored at the facility in a designated storage area. A small number of copermitteescontract to a service provider for application of pesticides (service providersmust be approved by the OPM). These products are generally used in small quantitiesand are not stored at the facility.The use of pesticides and herbicides at the airport does not result in significantdischarges to the land surface. During rainfall events, pesticide and herbicide residualsat application sites may be washed into the storm drain system. However, based on thesmall quantities used at the airport and the short half-life of most herbicides andpesticides, this activity represents a low potential to impact stormwater discharges.4.2 PollutantsAs required by Part 5.1.3.2, this section identifies potential stormwater pollutants. Themost common potential pollutant is fuel, followed closely by oil and grease. Theremaining potential pollutants, from most prevalent to least prevalent, are solvents,soaps/detergents, anti-freeze, lavatory waste, paint, used batteries, pesticides,herbicides, sediment, and landscape waste. These pollutants can be transported to thestormwater system as direct spills or indirectly from rainfall runoff that may mobilizeresidual contaminants.16

Locations of past spills are shown on Figure 3.The MSGP-2010 (Part 5.1.3.3) requires the SWPPP to include a list of significant spillsand leaks of toxic or hazardous pollutants that occurred in the three years prior to thedate this SWPPP was revised. Significant spills and leaks include, but are not limited to,release of oil or hazardous substances in excess of quantities that are reportable underSection 311 of the Clean Water Act (CWA) or Section 102 of the Comprehensive17

Environmental Response, Compensation and Liability Act (CERCLA). For the purposesof this SWPPP, the definition of significant spills has been broadened to include spills orleaks that entered the storm drain system.COPAD has an effective spill response program that includes the City of PhoenixAviation Department Rules and Regulation for Fuel Release and Releases of OtherRegulated Substances (R&R 01-01). This Rule establishes the procedures for internalreporting, response, clean up, documentation, and subsequent notifications associatedwith fuel releases and releases of other regulated substances occurring at GYR. The fulldocument may be found at the following link: http://skyharbor.com/pdf/RR_01-01-Fuel-Release.pdf or in Attachment 4.There have been no spills of toxic or hazardous pollutants in excess of reportablequantities under Section 311 of CWA or Section 102 of the CERCLA in the last three (3)years. Should a reportable spill occur, spill records, including descriptions of incidentsinvolving of significant spills, leaks, or other releases that resulted in discharges ofpollutants in stormwater to Waters of the United States (i.e., Gila River), thecircumstances leading up to the release and the measures taken to prevent therecurrence of such releases will be documented and maintained on COPAD’sStormwater Database and with the SWPPP in Attachment 5, as required by MSGP-2010Part 5.4.4.4 Unauthorized Non-Stormwater DischargesMSGP-2010 Part 1.1.3 lists the following allowable non-stormwater dischargesapplicable to GYR:1. Fire fighting system testing and maintenance, including hydrant flushing;2. Discharges related to installation and maintenance of potable water supplysystems, including disinfection and flushing activities, discharges resulting frompressure releases or overflows, and discharges from wells approved by ADEQfor drinking water use;3. Uncontaminated condensate from air conditioners, evaporative coolers, andother compressors and from the outside storage of refrigerated gases or liquids;4. Irrigation drainage and irrigation line flushing;5. Landscape watering provided all pesticides, herbicides, and fertilizer have beenapplied in accordance with the approved labeling; and6. Routine external building wash down that does not use detergents.All other non-stormwater discharges are considered unauthorized.18

Parts of the storm drain system at GYR are a continuation of Goodyear MunicipalSeparate Storm Sewer System (MS4) components originating from industrial facilitieslocated east of the airport through headwalls and catch basins. There is a potential forunauthorized non-stormwater discharges to enter the GYR storm drain system throughthese drainage ways.If an unauthorized non-stormwater discharge is identified, COPAD will followreporting requirements in Section 6.5 for Corrective Action.19

Section 5 - Description of Control MeasuresStormwater pollution prevention CMs include processes, procedures, schedules ofactivities, prohibitions on practices, and other management practices that prevent orreduce the discharge of pollutants to Waters of the United States (MSGP-2010).5.1 Selection of Control MeasuresMSGP-2010 Part 2.1.1 requires that COPAD and co-permittees assess the type andquantity of pollutants likely to be discharged in stormwater or allowable nonstormwaterfrom the facility when designing and implementing CMs. The CMs arerequired to incorporate one or more of the following principles:• Preventing stormwater from coming into contact with polluting materials is generallymore effective, and less costly, than trying to remove pollutants from stormwater.• Using CMs in combination is more effective than using CMs in isolation forminimizing pollutants in the facility’s stormwater discharge.• Minimizing impervious areas at the facility and infiltrating stormwater at the facilitycan reduce runoff and improve groundwater recharge and stream base flows in localstreams, although care must be taken to avoid groundwater contamination.• Attenuating flow using open vegetated swales and natural depressions can reduce instreamimpacts of erosive flows.• Conserving and/or restoring of riparian buffers help protect streams fromstormwater runoff and improve water quality.• Using treatment interceptors may be appropriate in some instances to minimize thedischarge of pollutants.COPAD has developed CMs based on the requirements and guidelines of the MSGP-2010 (Part 2.1) and specific operational requirements that address pollutants originatingfrom regulated activities. COPAD has taken into consideration the quantity and natureof the pollutants and their potential to impact the water quality of the receiving watersin selection of CMs.5.2 Control MeasuresMSGP-2010 lists specific structural and non-structural types of CMs that must beconsidered for implementation. This section describes how each is or will beimplemented. The specific CMs identified in the MSGP-2010 were determined to beappropriate for COPAD facilities. This section of the SWPPP includes a description ofthe CMs listed in MSGP-2010, Part 2.1. COPAD has further identified some of theseCMs with the specific activities that have potential to degrade stormwater, as describedin Section 4 above. The MSGP-2010 requires that COPAD consider and implement CMsin the following general categories:21

• Minimize Exposure• Good Housekeeping• Maintenance• Spill Prevention and Response• Erosion and Sediment Control• Management of Runoff• Salt Storage• Sector Specific Control Measures• Employee Training• Non-Stormwater Discharges• Litter, Garbage, and Floatable Debris• Dust Generation and Vehicle Tracking ofIndustrial MaterialsBecause not all co-permittees conduct all of the industrial activities described in Section 4,COPAD has organized CMs by industrial activity. Co-permittees can use the CMs thatapply to their activities. Attachment 3 contains CMs for each of the nine industrialactivities listed in Section 4, and a general CM that applies facility-wide. Each activityspecificCM lists the targeted sub-activities, target pollutants, specific proceduresaddressing the CM categories listed above, record keeping/reporting requirements, andstormwater pollution prevention considerations for the design of new facilities or upgradesto existing facilities. These CMs are in general used by COPAD and co-permittees and arebased on the requirements of the MSGP-2010 and COPAD-specific operationalrequirements.Some CM categories do not apply to GYR or are covered under good housekeepingrequirements. These are described below:Salt Storage: Salt storage is not conducted at GYR so no specific CMs have been developedfor this category.Sediment and Erosion Control / Dust Generation and Vehicle Tracking: MSGP-2010requires that the SWPPP identify areas with a potential for significant soil erosion due totopography, land disturbance (e.g., construction) or other factors and the structural,vegetative, and/or stabilization CMs that will be implemented to limit erosion. These arethe same areas likely subject to dust generation and vehicle tracking.Litter, Garbage, and Floatable Debris: Litter, garbage, and floatable debris are managedunder Good Housekeeping requirements at GYR, which are designed to prevent oreliminate any sources of Foreign Object Debris (FOD).22

Section 6 - Schedules and Procedures6.1 Control Measures MaintenanceMSGP-2010 Part 2.1.1.3 requires that CMs identified in the SWPPP must be maintainedin effective operating condition. When COPAD or a co-permittee discovers a CM that isnot operating effectively, maintenance must be performed within 14 days or prior to thenext measureable storm event, whichever is sooner.6.1.1 Co-permittee-Owned Control MeasuresRegular inspection and maintenance of co-permittee-owned CMs, such as spill kits,structural covers, and oil/water separators, are the responsibility of the co-permittee.Oil/water separators must be visually inspected on a regular basis and pumped outwhen necessary. Oil/water separator owners are required to maintain maintenance andinspection records for these structures. If necessary based on the types of discharge tothe separator, co-permittees are required to sample the material to be pumped for wasteprofiling to ensure it is properly manifested, transported, and disposed.Where treatment devices, facilities or interceptors are used in direct connection to thepublic storm drain system, those devices, facilities or interceptors shall be maintainedcontinuously in satisfactory and effective operation by the owner at their expense.The following Control Measure shall be implemented at all oil water separators (OWS)that discharge to the storm drain system:(1) monthly inspection of inlet area and OWS chambers for releases, oil, trash, debris,and oil accumulation,(2) monthly inspection of the OWS discharge point for releases or staining,(3) minimize stains, trash, debris, and non-stormwater to OWS inlet area, and(4) remove the OWS contents (and re-filling with clean water) in the event that oil isobserved in the OWS single and/or final chamber.Written records and documentation of all inspection, cleaning, repair, and maintenanceshall be provided at each annual stormwater inspection and maintained by the OWSoperator for a minimum of five years and made available to the City upon request.Failure to prevent releases from the OWS to the storm drain will subject a co-permitteeto a Notice of Violation and may result in conversion of the OWS to a sump or requireadditional engineering controls.COPAD conducts quarterly routine and annual comprehensive facility inspections(CFIs) of co-permittees’ facilities (see Section 6.3) to meet the inspection requirements inthe MSGP-2010 and to verify maintenance of co-permittee owned CMs. CMmaintenance identified during those inspections are discussed with the co-permittees at23

the time of the inspection, documented in writing to the affected co-permittees andtracked with other non-compliances as discussed in Section 6.3.6.1.2 City of Phoenix-Owned Control MeasuresCOPAD Operations Division is responsible for infrastructure (such as culverts, stormdrains, and outfalls) and City-owned structural CMs (such as OWS and spill kits) atGYR. They perform maintenance on CMs, as such needs are identified, includingrestocking spill kits as necessary.COPAD staff use sweepers to clean the airfield and parking lots on an as needed basis toprevent FOD and trash accumulation.The COP recycling contractor collects and recycles the used oil at the wasteaccumulation areas as well as at the Maintenance Building and the COP hazardouswaste transporter contractor disposes of the waste solvent. A contractor also conductsmaintenance of City-owned oil/water separators. COPAD inspects waste accumulationareas weekly. PECM inspects the OWSs annually. Waste from OWSs is profiledannually and pumped for disposal annually or when necessary.6.1.3 Spill Prevention and Response ProceduresMSGP-2010 Part 5.1.5.1 requires procedures for preventing and responding to spills andleaks. Spill response procedures are provided to co-permittees and others conductingindustrial activities at GYR. Spill response procedures are included in Attachment 6.Co-permittees subject to Spill Prevention Control and Countermeasures (SPCC)requirements develop and maintain SPCC Plans for their facilities. These plans must beprovided to PECM for upload to COPAD’s Stormwater Database.Spill records including descriptions of incidents of significant spills, leaks, or otherreleases that resulted in discharges of pollutants in stormwater to Waters of the UnitedStates (i.e., Gila River), the circumstances leading up to the release and the measurestaken to prevent the recurrence of such releases must be documented and maintainedwith the SWPPP in Attachment 5, as required by MSGP-2010 Part 5.4 and in theStormwater Database.6.1.4 TrainingEmployee training on the SWPPP provisions and MSGP-2010 requirements is requiredby MSGP-2010 Part 2.1.1.9 for PPT Members and anyone who works in areas whereindustrial materials or activities are exposed to stormwater or who is responsible forimplementing activities identified in the SWPPP. At GYR, PECM or its stormwaterconsultant conducts annual training for the PPT members (see Section 2.1) and includingCOPAD. This training is designed as a train-the-trainer presentation and co-permitteesare expected to pass the training on to their employees that have responsibility forSWPPP compliance.24

The annual training consists of a Microsoft PowerPoint presentation. PECM and theirstormwater consultants developed a web-accessible stormwater training program toincrease the dissemination of stormwater compliance information directly to tenantemployees. Co-permittee employees are able to access the training program through thestormwater website (http://skyharbor.com/stormwater) and print individualCertificates of Completion when they complete the training to document training wascompleted. PECM encourages co-permittees to use the online training to train theiremployees. If the online training is not used co-permittees’ employee training mustcover the same material covered in the online training and co-permittees must providePECM with a copy of the training used. Co-permittee employee training attendance isverified during annual Comprehensive Facility Inspections (CFIs) (see Section 6.3).Annual training covers the components and goals of the SWPPP (including the CMs inAttachment 3), new SWPPP requirements, visual monitoring, preparation for the annualCFIs, and a summary of the most prevalent issues of concern during the previous year’sinspections. In addition, PECM selects a special topic to be covered each year such asoil/water separator maintenance or SPCC plans. The 2013 training included aninteractive visual monitoring exercise, examining samples and filling in a visualmonitoring form, and a scavenger hunt to locate information in the SWPPP.Training sessions are generally conducted prior to annual CFIs to refresh co-permitteeson the SWPPP requirements. The training sessions last approximately two hours andtypically, a training session is offered at GYR, alternatively, if tenants cannot attend theGYR training, multiple training sessions are offered at Sky Harbor International (PHX)at different times over the course of several days to accommodate shift workers.PPT Members/COPAD department representatives are notified by phone or e-mail ofthe training dates and location. The Annual Training Attendance Form provided inAttachment 7 is used to document attendance. COPAD’s training attendance sheets areuploaded to the Stormwater Database.6.2 MonitoringAs required by MSGP-2010 Part 8.S.7, sector-specific benchmark analytical monitoring isnot required because GYR and co-permittees do not conduct deicing or store any deicingchemicals (see Section 1.3). As required by MSGP-2010 Part 6.2.3, discharges directly toimpaired streams must conduct analytical monitoring; however, since GYR dischargesto Bullard Wash, not an impaired stream, monitoring is not required. A Sampling andAnalysis Plan is not applicable to GYR because analytical monitoring is not required.6.3 InspectionsAs required by MSGP-2010, PECM or its stormwater consultants conduct routine facilityinspections, visual assessments, and annual CFIs for all co-permittees accompanied byeach co-permittee PPT member. As required by MSGP-2010 Part 4.3, the CFIs are to beconducted in the winter, which is the period when deicing is most likely to occur;however, because no deicing activities occur at GYR, PECM conducts the CFIsconcurrently with the other Phoenix airports. The MSGP-2010 Part 8.S.6.1 requirement25

to conduct monthly inspections during the deicing season (generally November –February) does not apply to GYR.PECM maintains all inspection data in the Stormwater Database. The database includescontact information for each co-permittee in addition to a list of the activities conductedat each facility subject to SWPPP compliance. The database also tracks the inspectionresults and documents actions taken to address non-compliances identified duringinspections. The information in the database is updated during the annual CFIs and asneeded during the year to address changes in co-permittees operations.6.3.1 Routine Quarterly Facility InspectionsPECM or its stormwater consultant conducts the routine quarterly facility inspections ofco-permittees facilities. These inspections are unscheduled unless co-permitteeparticipation is needed for access. As required by MSGP-2010 Part 4.1.1, at least one ofthe routine inspections each year is conducted during or within 24 hours of ameasurable storm event.During the routine inspections, inspectors look for:• Evidence demonstrating that previously unidentified discharges of pollutants haveoccurred from the site;• CMs needing maintenance or repair;• Failed CMs needing replacement;• Evidence of other deviations from the SWPPP or MSGP-2010; and• Additional CMs needed to comply with MSGP-2010 requirements.Inspection results are recorded on the Routine Inspection Form presented in Attachment8. This form includes the following information:• Inspection date and time;• Name(s) and signature(s) of inspector(s);• Weather information and description of discharges occurring at the time of theinspection;• Evidence demonstrating that previously unidentified discharges of pollutants haveoccurred from the site;• Control measures needing maintenance repairs;• Failed control measures that need replacement;• Other evidence of deviations from the permit or SWPPP observed; and• Additional control measures needed to comply with the permit requirements.At the conclusion of each inspection, the inspection findings will be discussed with theco-permittee. An email identifying major and minor SWPPP non-compliances will besent to the co-permittee within 72 hours of the inspection.26

Identified non-compliances must be addressed within 14 days of receiving the emailidentifying non-compliances or prior to the next measureable storm event, whichever issooner. The co-permittees are required to provide PECM written notificationdocumenting how and when each stormwater management concern was addressed. Ifmore than 14 days is required to address any non-compliance concerns, the co-permitteemust provide PECM written notification of the rationale for the extended schedule andthe projected completion date.Completed Routine Inspection Forms and all co-permittee responses are uploaded to theStormwater Database and are available with the SWPPP, as required by MSGP-2010 Part5.4.6.3.2 Visual Assessment of Stormwater DischargesUnder MSGP-2010 Part 4.2, GYR is required to conduct four visual assessments ofstormwater from the airport outfalls annually: two during the summer wet season (June1 – October 31) and two during the winter wet season (November 1 – May 31). Asdiscussed in Section 6.2, analytical stormwater monitoring is not required at GYR.Visual assessments will be performed at outfalls (see Figure 2) on stormwater dischargesthat occur at least 72 hours (three (3) calendar days) following the conclusion of aprevious discharge.As required by MSGP-2010, a stormwater sample from each outfall for visualassessments must be collected within the first 30 minutes of discharge or as soonthereafter as practicable. If the sample cannot be collected within the first 30 minutes offlow, it will be noted on the on the visual assessment form along with the reason for thedeviation. In accordance with MSGP-2010 Part 4.2.1, the visual assessment shall beconducted using a sample in a clean, clear glass or plastic container in a well-lit area.The samples shall be visually inspected for the following water quality characteristics:• Color• Odor• Clarity• Floating solids• Settled solids• Suspended solids• Foam• Oil sheen• Other obvious indicators of pollutionVisual assessment results are recorded on the Visual Assessment Form and stored onCOPAD’s Stormwater Database, a blank form is provided in Attachment 9. If there areno qualifying rain events or if a sample could not be collected due to adverse conditionsfor a given quarter, the Visual Assessment Form shall be marked indicating the reasonwhy a sample was not assessed. Adverse conditions are those that are dangerous orcreate inaccessibility for personnel, such as local flooding, high winds, or electricalstorms, or situations that otherwise make sampling unsafe.Completed Visual Assessment Forms are uploaded to the Stormwater Database and areavailable with the SWPPP, as required by MSGP-2010 Part 5.4.27

6.3.3 Comprehensive Facility InspectionsCFIs are generally conducted in January to avoid interfering with the holiday flightoperations in November and December. The Stormwater Database is used to generateCFI notification letters for co-permittees and COPAD. Inspectors contact each copermitteeto confirm the inspection date, time, and meeting location. If a schedulingconflict arises, co-permittees contact the inspector to reschedule.As the first step at each inspection, the inspector confirms contact information and listedactivities potentially impacting stormwater quality. Then the inspector surveys areaswhere industrial materials or activities may be exposed to stormwater for compliancewith SWPPP provisions. The inspector looks for and collects records of:• Industrial materials, residue, or trash that may have or could come in contact withstormwater;• Leaks or spills from industrial equipment, drums, tanks, or other containers;• Offsite tracking of industrial or waste materials or sediment where vehicles enter orexit the site;• Tracking or blowing of raw, final, or waste materials from areas of no exposure toexposed areas;• CMs needing replacement, maintenance, or repair; and• Copies of personnel stormwater training records.Inspectors may question co-permittee personnel for basic knowledge of CMrequirements. Additionally, inspectors may request to review inspection and/ormaintenance records. The annual CFIs are also an opportunity for co-permitteespersonnel to provide input on the SWPPP and the efficacy of CMs in the SWPPP.During the inspection, the inspector records observations and information gathered onthe Comprehensive Facility Inspection Form provided in Attachment 10. Instances ofSWPPP compliance and non-compliance are documented with photographs, providingthere are no company policies restricting or preventing photographic documentation.The co-permittee representative(s) reviews inspection results before leaving the site.Inspection results and photographs are entered into the Stormwater Database. Thedatabase generates letters that are emailed/mailed to the co-permittee/. The letterscontain a brief explanation of SWPPP requirements, instances of SWPPP major andminor non-compliances, recommendations for resolution of the non-compliances, orrecognition of especially effective SWPPP compliance (if applicable) and PECM contactinformation. Major non-compliances, including missing or non-functioning structuralCMs, must be addressed within 14 days or prior to the next measureable storm event,whichever is sooner. Minor concerns, including problems with documentation,reporting, and non-structural CMs, must be addressed within 90 days.The inspected co-permittee is required to provide PECM written notificationdocumenting how and when each stormwater management concern was addressed. If28

more than 14 days is required to address any major non-compliance, the co-permitteemust provide PECM written notification of the rationale for the extended schedule andthe projected completion date.In some instances, follow up inspections are conducted to confirm compliance. Lack ofaction to address non-compliance concerns can subject a co-permittee to a Notice ofViolation or other penalty under Stormwater Enforcement Procedures and Civil PenaltyPolicy at GYR, included as Attachment 11.Inspection results (with photographs) and co-permittee responses are uploaded to theStormwater Database and are available with the SWPPP as required by MSGP-2010 Part5.4. Because GYR discharges within 2.5 miles of an impaired stream the results of theCFIs are submitted with the Annual Report as required by MSGP-2010 Part 4.3.2. TheAnnual Report summarizes the inspection results as well as other findings of the CFIsand may be used to revise the SWPPP.6.4 Substantially Identical OutfallsPECM has not designated any substantially identical outfalls as allowed in MSGP Part5.1.5.2 at this time. PECM may conduct an assessment for such outfalls during futurerevisions of this SWPPP.6.5 Corrective ActionsAs required by MSGP-2010 Part 3.1, PECM has established procedures to address thefollowing procedures resulting in or from the failure of a CM:• An unauthorized discharge to a Water of the United States (i.e., Bullard Wash);• The permittee becomes aware or ADEQ determines that the facility’s dischargecauses or contributes to an exceedance of an applicable water quality standard; and• ADEQ determines that modifications to the control measures are necessary to meetthe requirements of the MSGP-2010 Part 2.2.Within 72 hours of identifying one of these corrective action triggers, PECM willdocument the discovery with the following information on the Corrective Action Form:• Identification of the triggering condition• Description of the problem identified• Date the problem was identifiedWithin 14 calendar days, PECM will document the following information in a CorrectiveAction Report:• Summary of corrective action(s) taken or to be taken• Whether SWPPP modifications are required as a result of the discovery or correctiveaction29

• Date corrective action was or will be initiated• Date the corrective action was completed or is expected to be completeCorrective Action Forms and Corrective Action Reports (Attachment 12) will beuploaded to the stormwater database and are aviable with the SWPPP as required byMSGP-2010 Part 3.3.30

Section 7 - Reporting and Recordkeeping7.1 Annual ReportAs required by MSGP-2010 Part 7.2, PECM or its stormwater consultant prepares anAnnual Report for the annual reporting period from June 1 to May 31. The reportincludes:• Findings from the CFIs;• Corrective Action Forms and Reports;• Visual assessment results; and• The results of monitoring required by ADEQ.Copies of the Annual Reports are uploaded to the stormwater database and are availablewith the SWPPP as Attachment 13, as required by MSGP-2010 Part 7.2. Because theairport discharges within 2.5 miles of an impaired stream (i.e., Gila River) GYR isrequired to submit the Annual Report to ADEQ, according to MSGP-2010 Part 7.2.

R18-9-C903(A) and remain in force and effect. If the operator isauthorized to discharge under this permit prior to the expiration date, any discharges authorized underthis permit will automatically remain covered by this permit until the earliest of:1. The operator submits a timely, complete, and accurate NOI requesting authorization todischarge under a renewal or revision of this permit and ADEQ issues an Authorization toDischarge; or2. The operator submits a Notice of Termination; or3. ADEQ denies coverage under this general permit or denies or issues coverage under anindividual permit or other alternative permit for the facility’s discharges; or4. A formal permit decision is made by ADEQ not to reissue this general permit, at which timeADEQ will identify a reasonable time period for covered dischargers to seek coverage underStormwater Discharges Associated with Industrial Activity 6

Non-mining MSGP 2010 General Permitan alternative general permit or an individual permit. Coverage under this permit will cease atthe end of this time period.1.4 Terminating CoverageTo terminate permit coverage, the permittee shall submit a complete and accurate Notice ofTermination (NOT) form to the address listed in Part 7.6. Other NOT options (i.e., electronic submission)may also be used if ADEQ makes the information available on the Internet of by public notice. Thefacility’s authorization to discharge under this permit terminates at midnight of the day that a completeNOT form is received by the department. The permittee shall submit an NOT within 30 calendar daysafter a new owner or operator assumes ownership of or has taken over responsibility for the facility.The permittee shall also submit an NOT when there are not or no longer will be discharges ofstormwater associated with industrial activity from the facility, and the permittee has alreadyimplemented necessary sediment and erosion controls as required by Part 2.1.1.5.The permittee is responsible for meeting the terms and conditions of this permit until the facility’sauthorization is terminated.1.5 No Exposure ExclusionOperators may claim relief from the requirement to obtain a permit under the ‘‘no exposure’’provision by submitting a No Exposure Certification to ADEQ at the address listed in Part 7.6. The NoExposure Certification incorporates the conditions of 40 CFR 122.26(g)(4)(iii) and must be submittedonce every five years.[Note: See A.A.C. R18-9-A902(H) and the Guidance Manual for Conditional Exclusion fromStormwater Permitting Based on “No Exposure” of Industrial Activities to Stormwater found atwww.epa.gov/npdes/stormwater .]In addition to submitting a No Exposure Certification, the operator shall allow ADEQ and/or therepresentatives of a regulated MS4 (where there is a stormwater discharge to the MS4) to inspect thefacility and to make such inspection reports publicly available upon request. The facility must also submita copy of the No Exposure Certification to the operator the regulated MS4 into which the facilitydischarges (if applicable). All No Exposure Certifications must be signed in accordance with the signatoryrequirements of Appendix B, Subsection 9. The No Exposure Certification is nontransferable.Permittees operating under a ‘no exposure exclusion’ that has been accepted by ADEQ are notrequired to submit an NOT. However, if at any time the facility can no longer satisfy the conditions of noexposure, renewed permit coverage is required and the owner / operator must submit an NOI requestingcoverage and comply with the permit. ADEQ retains the authority to deny this exclusion (and requireauthorization under an individual permit) if it determines that the discharge causes, has a reasonablepotential to cause, or contributes to an exceedance of an applicable water quality standard, includingdesignated uses.1.6 Alternative Permits1.6.1 ADEQ Requiring Coverage under an Alternative AZPDES PermitADEQ may require an operator to obtain authorization to discharge under either an individualAZPDES permit or an alternative AZPDES general permit in accordance with A.A.C. R18-9-C902(A). IfADEQ requires an operator to apply for an individual permit, any applications shall be submitted within120 calendar days, unless ADEQ provides an extended deadline. In addition, a discharger alreadyauthorized under this permit, will be notified of a deadline to file a permit application. Coverage under thispermit will terminate immediately if the facility fails to submit an individual AZPDES permit application bythe specified deadline. ADEQ may take appropriate enforcement action for any unpermitted discharge.1.6.2 Permittee Requesting Coverage under an Alternative PermitAn applicant may elect to forego coverage under this general permit by applying for an individualStormwater Discharges Associated with Industrial Activity 7

Non-mining MSGP 2010 General Permitpermit. In such a case, the applicant must submit an individual permit application in accordance with therequirements of A.A.C. R18-9-B901(B)(2) to the Department at the address listed in Part 7.6 and includereasons supporting the request. The request may be granted by issuance of an individual permit orauthorization of coverage under an alternative general permit if the Department finds that the reasons areadequate to support the request.When an individual AZPDES permit is issued to the applicant or the applicant is authorized todischarge under an alternative AZPDES general permit, the authorization to discharge under this permitis terminated on the effective date of the individual permit or the date of authorization of coverage underthe alternative general permit.2.0 Control Measures, Numeric Effluent Limitations and Water Quality Standards.In Part 2.1 (Control Measures) and in Part 8 (Sector-Specific Requirements for Industrial Activity),the term “minimize” means reduce and/or eliminate to the extent achievable using control measures thatare technologically available, economically practicable and achievable in consideration of best industrypractice to meet any applicable numeric effluent limitations in Part 2.2.1 and the water-quality basedrequirements in Parts 2.2.2 and 2.2.3.The requirement to implement control measures in accordance with Part 2.1 applies to allfacilities. Part 8 contains additional control measures imposed on a sector-specific basis. In some cases,sector-specific provisions in Part 8 modify the terms of the general control measures set forth in Part 2.1.2.1 Control MeasuresThe permittee shall select, design, install, and implement control measures (including bestmanagement practices), as appropriate, to ensure the discharge meets the requirements of Part 2.2. Theselection, design, installation, and implementation of these control measures must be in accordance withgood engineering practices and manufacturer’s specifications. If construction or a change in design,operation, or maintenance at the facility significantly changes the nature of pollutants discharged instormwater, or significantly increases the quantity of pollutants discharged, the permittee shall review theselection, design, installation, and implementation of the facility’s control measures to determine ifmodifications are necessary to meet the requirements of this permit. If the facility’s control measures arenot achieving their intended effect of minimizing pollutant discharges, the permittee shall modify theseand/or add additional control measures to meet requirements of this permit. Regulated stormwaterdischarges from the facility include stormwater run-on that commingles with stormwater dischargesassociated with industrial activity at the facility.The permittee shall consider all of the control measures listed below for implementation at thefacility and select those that the permittee determines are appropriate, given the nature of the site, tomeet the requirements set forth in Parts 2.1.1 and 2.2. The control measures listed below are notintended to be an exclusive list of acceptable control measures. In preparing the SWPPP in accordancewith the requirements in Part 5 of this permit, the permittee shall explain the basis for the selection of thecontrol measures to be utilized at the facility.2.1.1 Control Measure Selection and Design ConsiderationsThe permittee shall assess the type and quantity of pollutants likely to discharge in stormwater orallowable non-stormwater from the facility when designing and implementing control measures. Thepermittee shall select and design control measures incorporating one or more of the following principles:Preventing stormwater from coming into contact with polluting materials is generally moreeffective, and less costly, than trying to remove pollutants from stormwater;Using control measures in combination is more effective than using control measures inisolation for minimizing pollutants in the facility’s stormwater discharge;Minimizing impervious areas at the facility and infiltrating runoff onsite (including bioretentioncells, green roofs, and pervious pavement, among other approaches) can reduce runoff andimprove groundwater recharge and stream base flows in local streams, although care mustbe taken to avoid ground water contamination;Stormwater Discharges Associated with Industrial Activity 8

Non-mining MSGP 2010 General PermitAttenuating flow using open vegetated swales and natural depressions can reduce in-streamimpacts of erosive flows;Conserving and/or restoring of riparian buffers help protect streams from stormwater runoffand improve water quality; andUsing treatment interceptors (e.g., swirl separators and sand filters) may be appropriate insome instances to minimize the discharge of pollutants.2.1.1.1 Minimize Exposure. The permittee shall minimize the exposure of manufacturing,processing, and material storage areas (including loading and unloading, storage, disposal,cleaning, maintenance, and fueling operations) to rain, snow, snowmelt, and runoff byimplementing measures such as the following: Locating industrial materials and activities inside or protect them with storm resistantcoverings (although significant enlargement of impervious surface area is notrecommended) Covering fueling area(s) or minimize stormwater run-on/runoff to fueling area(s); Use grading, berming, or curbing to prevent runoff of contaminated flows and divert runonaway from these areas; Locating materials, equipment, and activities so that leaks are contained in existingcontainment and diversion systems (confine the storage of leaky or leak-prone vehiclesand equipment awaiting maintenance to protected areas); Using spill/overflow protection and cleanup equipment; Draining fluids from equipment and vehicles prior to on-site storage or disposal; Performing all cleaning operations indoors, under cover, or in bermed areas that preventrunoff and run-on and also that capture any overspray; and Ensuring that all washwater drains to a proper collection system (i.e., not the stormwaterdrainage system).The discharge of vehicle and equipment washwater, including tank cleaning operations, is notauthorized by this permit. These wastewaters must be covered under a separate AZPDES permit,discharged to a sanitary sewer in accordance with applicable industrial pretreatmentrequirements, or disposed of otherwise in accordance with applicable law.2.1.1.2 Good Housekeeping. The permittee shall implement good housekeeping measures for allexposed areas that are potential sources of pollutants. Such measures may include: Sweeping at regular intervals; Keeping materials orderly and labeled; Storing materials in appropriate containers; Cleaning up spills and leaks promptly using dry methods (e.g., absorbents) to prevent thedischarge of pollutants; Using drip pans and absorbents under or around leaky vehicles and equipment or storeindoors where feasible.2.1.1.3 Maintenance. The permittee shall regularly inspect, test, maintain, and repair all industrialequipment and systems that have the potential for exposure to stormwater to avoid situations thatmay result in leaks, spills, and other releases of pollutants to stormwater discharged from the site.The permittee shall maintain all control measures and equipment in effective operating condition.Nonstructural control measures must also be diligently maintained (e.g., spill response suppliesavailable, personnel appropriately trained). If the permittee discovers control measures are notachieving the intended effect of minimizing pollutant discharges (i.e., control measures needrepair or replacement), the permittee shall make any necessary changes within 14 calendar daysfollowing discovery, or before the next measurable storm event (see Part 6.1.2.2), whichever issooner, to ensure compliance with the applicable numeric effluent limitations in Part 2.2.1 andStormwater Discharges Associated with Industrial Activity 9

ADEQ expects that compliance with otherconditions in this permit will control discharges as necessary to not cause or contribute to an exceedanceof an applicable water quality standard (A.A.C.R18-11, Article 1). However, if at any time the permitteebecomes aware, or ADEQ determines, that the facility’s discharge causes or contributes to anexceedance of an applicable water quality standard, the permittee shall take corrective action as requiredin Part 3.1, document the corrective actions as required in Parts 3.3 and 5.4, and report the correctiveactions to ADEQ as required in Part 7.2.Additionally, ADEQ may impose additional water quality-based requirements on a site-specificbasis, or require the operator to obtain coverage under an individual permit in accordance with Part 1.6.1,if information in the Notice of Intent (NOI), required reports, or from other sources indicates thedischarges are not controlled as necessary to not cause or contribute to an exceedance of an applicablewater quality standard.2.2.3 Discharges to Water Quality Impaired Waters2.2.3.1 Existing Discharges to an Impaired Water with an Approved TMDL. If the discharge isto an impaired water with, or is otherwise referenced in an approved TMDL, the Department mayrequire, as a condition of authorization, additional limits, controls, or monitoring necessary to beconsistent with the assumptions of any available wasteload allocation in the TMDL. Alternatively,ADEQ will advise the permittee if coverage under an individual permit is necessary in accordancewith Part 1.6.2.2.3.2 Existing Discharges to an Impaired Water without an Approved TMDL. If the dischargeis to an impaired water without an approved TMDL, the permittee shall comply with Part 2.2.2 andthe monitoring requirements of Part 6.2.3. This subsection applies to discharges directly toimpaired waters as well as to situations where ADEQ determines that the facility’s discharge isnot controlled as necessary to meet water quality standards in a downstream water segment,even if the discharge is to a receiving water that is not specifically identified on a Section 303(d)list.2.2.3.3 New Discharges to an Impaired Water. If the permittee’s authorization to discharge underthis permit relied on Part 1.1.4.5 for a discharge to an impaired water, the permittee shallimplement and maintain any control measures or conditions on the facility that enabled it tobecome eligible under Part 1.1.4.5. The permittee shall modify such measures or conditions asnecessary in accordance with any Part 3 corrective actions.

Non-mining MSGP 2010 General Permit4.1.3 Exceptions to Routine Facility InspectionsInactive and Unstaffed Sites: The requirement to conduct routine facility inspections on aquarterly basis does not apply to a facility that is inactive and unstaffed, provided that noindustrial materials or activities are exposed to stormwater. Such a facility is only required toconduct an annual comprehensive facility inspection in accordance with the requirements of Part4.3. To invoke this exception, the permittee shall do the following:Maintain a statement in the SWPPP pursuant to Part 5.1.5.2 indicating that the facility isinactive and unstaffed, and that there are no industrial materials or activities exposed toprecipitation, in accordance with the substantive requirements in 40 CFR 122.26(g)(4)(iii).The statement must be signed and certified in accordance with Appendix B, Subsection9.If circumstances change and industrial materials or activities become exposed tostormwater or the facility becomes active and/or staffed, this exception no longer appliesand the permittee shall immediately resume quarterly inspections.If, during the period of coverage under this permit, the facility becomes qualified for theinactive and unstaffed exception, and there are no industrial materials or activitiesexposed to stormwater, then the permittee shall include the same signed and certifiedstatement as above and retain it pursuant to Part 5.4.For permittees with inactive and unstaffed facilities that are unable to meet the “no industrialmaterials or activities exposed to stormwater” standard, the frequency of inspections is reducedto one routine inspection and one CFI each calendar year. These two inspections shall beconducted in the opposing wet seasons and at least three months apart. The SWPPP shallinclude documentation that the facility is unable to meet this standard and the results of theinspections. Compliance with any additional sector-specific conditions in Part 8 is still required.4.2 Visual Assessment of Stormwater DischargesThe permittee shall perform two visual assessments during the summer wet season and twovisual assessments during the winter wet season when the facility is discharging.Wet seasons, for the purposes of visual assessments, are defined as follows: Summer wet season: June 1 – October 31 Winter wet season: November 1 – May 31The term ‘wet season’ applies statewide and includes areas of the state where freezingconditions exist that prevent runoff from occurring for extended periods. In areas where freezingconditions exist, the four visual assessments may be distributed during seasons whenprecipitation runoff occurs.Visual assessment monitoring requirements in this permit begin immediately after authorization todischarge is received by the permittee unless authorization is received 90 calendar days or moreafter a wet season has begun, in which case visual assessment monitoring shall commence withthe start of the next wet season.4.2.1 Visual Assessment ProceduresVisual assessment samples are not required to be collected consistent with 40 CFR Part 136procedures.The visual assessment shall be made:Of a sample in a clean, clear glass, or plastic container, and examined in a well-lit area;On samples collected within the first 30 minutes of an actual discharge from a storm event. Ifit is not possible to collect the sample within the first 30 minutes of discharge, the samplemust be collected as soon as practicable after the first 30 minutes and the permittee shalldocument why it was not possible to take samples within the first 30 minutes. In the case ofStormwater Discharges Associated with Industrial Activity 15

Non-mining MSGP 2010 General Permitsnowmelt, samples shall be taken during a period with a measurable discharge from thefacility (see also Part 6.1.2.3); andOn discharges that occur at least 72 hours (3 calendar days) from a previous discharge (seealso Part 6.1.2.2).The permittee shall visually inspect the sample for the following water quality characteristics:Color;Odor;Clarity;Floating solids;Settled solids;Suspended solids;Foam;Oil sheen; andOther obvious indicators of stormwater pollution.4.2.2 Visual Assessment DocumentationThe permittee shall document the results of the visual assessments and maintain thisdocumentation with the SWPPP as required in Part 5.4. The visual assessment findings need not besubmitted to ADEQ, unless specifically requested by the Department. At a minimum, the documentationof the visual assessment shall include:Sample location(s);Sample collection date and time, and visual assessment date and time for each sample;Personnel collecting the sample and performing visual assessment, and their signatures;Nature of the discharge (i.e., runoff or snowmelt);Results of observations of the stormwater discharge;Probable sources of any observed stormwater contamination; andIf applicable, why it was not possible to take samples within the first 30 minutes.4.2.3 Exceptions to Visual AssessmentsAbsence of Discharge: If no storm event results in a discharge from the facility or outfall(s) duringa wet season, the permittee is excused from visual assessment for the facility or outfall(s) for thatseason provided the permittee documents in the monitoring records and retains with the SWPPPwhy a sample could not be collected.Adverse Conditions: Adverse conditions are those that are dangerous or create inaccessibility forpersonnel, such as local flooding, high winds, or electrical storms, or situations that otherwisemake sampling unsafe.When adverse conditions prevent the collection of either visual assessment sample in a given wetseason, the permittee shall document those conditions with the SWPPP and resume visualassessment monitoring in the subsequent wet season.Inactive and unstaffed sites: The requirement for a routine visual assessment does not apply at afacility that is inactive and unstaffed, provided that no industrial materials or activities are exposedto stormwater. To invoke this exception, the permittee shall do the following:Maintain a statement in the SWPPP as required in Part 5.1.5.2 indicating that the facilityis inactive and unstaffed, and that there are no industrial materials or activities exposedto precipitation, in accordance with the substantive requirements in 40 CFR122.26(g)(4)(iii).

Non-mining MSGP 2010 General Permitto Part 7 for additional reporting and recordkeeping requirements.6.1 Analytical Monitoring Procedures6.1.1 Analytical Monitoring Locations6.1.1.1 Monitored OutfallsApplicable monitoring requirements apply to each outfall authorized by this permit. If the facilityhas two or more outfalls believed to discharge substantially identical stormwater and/or allowable nonstormwater,based on the similarities of the general industrial activities and control measures, exposedmaterials that may significantly contribute pollutants to stormwater, and runoff coefficients of theirdrainage areas, the permittee may monitor the discharge at just one of the outfalls and report that theresults also apply to the substantially identical outfall(s). The allowance for monitoring only one of thesubstantially identical outfalls is not applicable to any outfalls with numeric effluent limitations set forth inPart 2.2.1. The permittee is required to monitor each outfall covered by a numeric effluent limitation asidentified in Part 6.2.2.6.1.1.2 Commingled Discharges.If discharges authorized by this permit commingle with discharges not authorized under thispermit, any required sampling of the authorized discharges must be performed at a point before they mixwith other unauthorized discharges to the extent practicable.6.1.1.3 Monitoring for Allowable Non-Stormwater DischargesUnless otherwise specified by ADEQ, permittees are required to monitor allowable nonstormwaterdischarges (as delineated in Part 1.1.3) only when they are commingled with stormwaterdischarges associated with industrial activity.6.1.2 Monitoring Events6.1.2.1 Monitoring Periods.Monitoring requirements in this permit begin within 90 calendar days of receiving theDepartment’s authorization to discharge. The required monitoring events may be distributed duringseasons when precipitation occurs, or when snowmelt results in a measurable discharge from the site.Wet seasons, for the purposes of analytical monitoring, apply statewide and are defined asfollows:Summer wet season: June 1 – October 31Winter wet season: November 1 – May 31The term ‘wet season’ includes areas of the state where freezing conditions exist that preventrunoff from occurring for extended periods. In areas where freezing conditions exist, the requiredmonitoring and sample collection may be distributed during seasons when precipitation runoff, either asmelting snow or rain mixed with melting snow, occurs.6.1.2.2 Measurable Storm Events.All required monitoring must be performed on a storm event that results in a discharge from thefacility (“measurable storm event”) that follows the preceding measurable storm event by at least 72 hours(3 calendar days). The 72 hour (3 day) storm interval does not apply if the permittee is able to documentthat less than a 72 hour interval is representative for local storm events during the sampling period. In thecase of snowmelt, the monitoring must be performed at a time when a measurable discharge occurs atthe site.For each monitoring event, except snowmelt monitoring, the permittee shall identify the personperforming the monitoring, the date and estimated duration (in hours) of the rainfall event, estimatedrainfall total (in inches) for that rainfall event, and time (in days) since the previous measurable stormStormwater Discharges Associated with Industrial Activity 24

Non-mining MSGP 2010 General Permitevent. For snowmelt monitoring, the permittee shall identify the sample as ‘snowmelt’ and the date of thesampling event.6.1.2.3 Sample Type.The permittee shall take a minimum of one grab sample from a discharge resulting from ameasurable storm event that produces a sufficient volume to allow collection of a sample. With theexception of samples to be analyzed for Suspended Sediment Concentration (SSC), samples must becollected within the first 30 minutes of a measurable storm event. If it is not possible to collect the samplewithin the first 30 minutes of a measurable storm event, the sample must be collected as soon aspracticable after the first 30 minutes and documentation must be kept with the SWPPP explaining why itwas not possible to take samples within the first 30 minutes. Samples for SSC shall be collected 48 hoursafter the storm event that resulted in a measureable discharge. In the case of snowmelt, samples must betaken during a period with a measurable discharge.6.1.2.4 Adverse Conditions.When adverse conditions as described in Part 4.2.3 prevent the collection of either analyticalsample in a given wet season, the permittee shall document those conditions with the SWPPP andresume analytical monitoring in the subsequent wet season. Adverse conditions do not exempt thepermittee from the requirement to file a discharge monitoring report (DMR) in accordance with thefacility’s sampling schedule. The permittee shall report any failure to monitor as specified in Part 7.1indicating the basis for not sampling during the usual reporting period.6.1.3 Sampling and Analysis Plan.The permittee shall develop a written SAP covering all analytical monitoring required by thispermit. The SAP shall be a part of the SWPPP as either an appendix or a separate SWPPP section. TheSAP shall include the following:6.1.3.1 Sample Collection, Preservation, Tracking, and Handling Information Designate and train personnel to collect, maintain, and handle samples in accordancewith the appropriate sample protocols. Identify water quality parameters/pollutants to be sampled including any pollutant(s) ofconcern in accordance with Parts 6.2.3 and 6.2.4; Identify the required sample analyses and associated analytical methods (analyticallaboratory and field analyses). Written procedures for:o Sample collection (equipment and containers, calibration procedures, document siteconditions during sampling, field notes and conditions under which the sample wastaken),oooPreservation (sample preparation to meet holding times),Tracking (including chain-of-custody procedures), andHandling (packing, transporting and shipping procedures to maximize sampleintegrity).6.1.3.2 Calibration and Maintenance of Monitoring Equipment.All monitoring instruments and equipment (including permittee’s field instruments for measuringpH and turbidity) shall be calibrated and maintained in accordance with manufacturer’s recommendations.6.1.3.3 Analytical Methods and Laboratories.Other than parameters required to be sampled at the time of sample collection (e.g., fieldparameters), all samples shall be analyzed by a laboratory that is licensed by the Arizona Department ofHealth Service (ADHS) Office of Laboratory Licensure and Certification. Identification of the analyticalStormwater Discharges Associated with Industrial Activity 25

Non-mining MSGP 2010 General Permitmethods and related limits of detection (if applicable) for each parameter is required. The samples shallbe analyzed using analytical methods with a limit of quantitation (LOQ) that is at or below the benchmarkconcentrations, ELGs or other criteria specified in this permit. If all methods have LOQs higher than thespecific criteria, the samples shall be analyzed using the analytical method with the lowest LOQ.All laboratory analyses shall be conducted according to test procedures specified in 40 CFR 136,unless other test procedures have been specified in this general permit. This requirement does not applyto parameters that require analysis at the time of sample collection as long as the testing methods usedare approved by ADHS. The permittee may conduct field analysis of turbidity if the permittee hassufficient capability (qualified and trained employees, properly calibrated and maintained fieldinstruments, etc.) to properly perform the field analysis.6.1.3.4 Records.The permittee shall retain records of all stormwater monitoring information and reports as part ofthe SWPPP in accordance with Part 7.5 and any additional requirements in Appendix B, Subsection 11 ofthis permit.6.2 Required Monitoring.This permit includes four types of required analytical monitoring, one or more of which may applyto the facility’s discharge: Benchmark monitoring (see Part 6.2.1) Effluent limitations monitoring (see Part 6.2.2); Impaired waters monitoring (see Part 6.2.3); and Additional monitoring as required by ADEQ (see Part 6.2.4).When more than one type of monitoring for the same parameter at the same outfall applies (e.g.,total suspended solids once per year for an effluent limitation and twice per wet season for benchmarkmonitoring at a given outfall), a single sample may be used to satisfy both monitoring requirements.All required monitoring shall be conducted in accordance with the procedures described inAppendix B, Subsection 11.D.6.2.1 Benchmark Monitoring.This permit stipulates pollutant benchmark concentrations for certain industry sectors. Thebenchmark concentrations are not effluent limitations; a benchmark exceedance, therefore, is not apermit violation. Benchmark monitoring data are primarily to determine the overall effectiveness of thecontrol measures and assist the permittee in knowing when to apply additional corrective action(s) tocomply with the effluent limitations in Part 2.permit.Additional sector-specific benchmark monitoring requirements may be described in Part 8 of this6.2.1.1 Applicability of Benchmark Monitoring.The permittee shall monitor stormwater discharges for all benchmark parameters specifiedfor the primary industrial activity and any co-located industrial activities, applicable to thefacility’s discharge. The industry-specific benchmark concentrations are listed in the sectorspecificsections of Part 8. If the facility is in one of the industrial sectors subject tobenchmark concentrations that are hardness-dependent, the permittee must characterize forhardness established per Appendix D procedures and submit results to ADEQ with thebenchmark report. For discharges to:Perennial or intermittent waters, the hardness shall be of the surface water receiving thedischarge;Stormwater Discharges Associated with Industrial Activity 26

Non-mining MSGP 2010 General PermitEphemeral waters, the hardness shall be of the discharge leaving the facility.Samples must be analyzed consistent with 40 CFR Part 136 analytical methods and usingtest procedures with quantitation limits at or below benchmark values for all benchmarkparameters for which sampling is required (see Part 6.1.3.3).6.2.1.2 Benchmark Monitoring Schedule.Benchmark monitoring must be conducted four times annually, two times each wet season,as identified in Part 6.1.2.1, for the facility’s first full year of permit coverage. If four samplesare not collected during this period, the permittee must continue collecting samples until 4samples are obtained from all outfalls subject to benchmark monitoring. For facilities thatdischarge to ephemeral waters, see Part 6.2.1.5.6.2.1.3 Data EvaluationData not exceeding benchmarks: After collection of 4 samples (or in the case of dischargeto ephemeral waters, two samples, in accordance with Part 6.2.1.5), if the average of themonitoring values for any parameter does not exceed the benchmark, the permittee’smonitoring requirements are fulfilled for that parameter for the permit term. For averagingpurposes, a value of zero shall be used for any individual sample parameter, analyzed usingprocedures consistent with Part 6.2.1.1, which is determined to be less than the methoddetection limit. For sample values that fall between the method detection limit and thequantitation limit (i.e., a confirmed detection but below the level that can be reliablyquantified), use a value halfway between zero and the quantitation limit.Data exceeding benchmarks: After collection of 4 samples (or in the case of discharge toephemeral waters, two samples, in accordance with Part 6.2.1.5), if the average of themonitoring values for any parameter exceeds the benchmark (see Part 8), the permittee shallreview the selection, design, installation, and implementation of the control measures todetermine if modifications are necessary to meet the effluent limitations in this permit, andeither: Make the necessary modifications and continue monitoring four times annually, until 4additional samples (or in the case of discharge to ephemeral waters, two samples) arecollected that show the average does not exceed the benchmark; or Make a determination that no further pollutant reductions are technologically availableand economically practicable and achievable in light of best industry practice to meet thetechnology-based effluent limitations or are necessary to meet the water-quality-basedrequirements in Part 2 of this permit. In this case the permittee shall continue monitoringonce per wet season. The permittee shall also document the rationale for concludingthat no further pollutant reductions are achievable, and retain all records related to thisdocumentation with the SWPPP. The permittee shall also notify ADEQ of thisdetermination in the next benchmark monitoring report, which is recorded on thedischarge monitoring report (DMR) sent to the Department. See Part 7.1.3.If less than 4 benchmark samples have been taken, but the results are such that anexceedance of the 4 sample average is mathematically certain (i.e., if the sum of sampleresults to date is more than 4 times the benchmark level), this is considered a benchmarkexceedance. In such cases, the permittee shall review the selection, design, installation, andimplementation of the control measures to determine if modifications are necessary to meetthe water quality based requirements in this permit. The permittee shall document thesechanges in the SWPPP. If the permittee determines no changes to existing control measuresis required, the permittee shall document in the SWPPP. If after modifying the controlmeasures and conducting the required additional rounds of monitoring, the average stillexceeds the benchmark (or if an exceedance of the benchmark is mathematically certainprior to conducting the required additional rounds of monitoring), the permittee shall againreview the control measures and take one of the two actions above.Stormwater Discharges Associated with Industrial Activity 27

Non-mining MSGP 2010 General PermitNatural background pollutant levels: Following the first 4 rounds of benchmark monitoring(or sooner if the exceedance is triggered by less than 4 samples, see above), if the averageconcentration of a pollutant exceeds a benchmark value, and the exceedance of thebenchmark is attributable solely to the presence of that pollutant in the natural background,corrective actions and additional benchmark monitoring are not required, provided that: The average concentration of the benchmark monitoring results is less than or equal tothe concentration of that pollutant in the natural background; Documentation of the permittee’s supporting rationale for concluding that benchmarkexceedances are in fact attributable solely to natural background pollutant levels. Thisdocumentation must be maintained with the SWPPP, as required in Part 5.4. Thepermittee’s supporting rationale shall include any data previously collected by anyone(including data reported in the literature) that describe the levels of natural backgroundpollutants in the facility’s stormwater discharge; and Notify ADEQ on the final benchmark monitoring report that the benchmark exceedancesare attributable solely to natural background pollutant levels.Natural background pollutants include those substances that are naturally occurring in soilsor groundwater. Natural background pollutants do not include legacy pollutants from earlieractivity on the site, or pollutants in run-on from neighboring sources that are not naturallyoccurring.6.2.1.4 Exception for Inactive and Unstaffed Sites.The requirement for benchmark monitoring does not apply at a facility that is inactive andunstaffed, provided that no industrial materials or activities are exposed to stormwater. Toinvoke this exception, the permittee shall do the following:Maintain a statement onsite with the SWPPP stating that the facility is inactive andunstaffed, and that there are no industrial materials or activities exposed to stormwater inaccordance with the substantive requirements in 40 CFR 122.26(g) and sign and certifythe statement in accordance with Appendix B, Subsection 9; andIf circumstances change and industrial materials or activities become exposed tostormwater or the facility becomes active and/or staffed, this exception no longer appliesand the permittee shall immediately begin complying with the applicable benchmarkmonitoring requirements under Part 6.2.1 as if it were the permittee’s first year of permitcoverage. The permittee shall indicate in the first benchmark monitoring report that thefacility has materials or activities exposed to stormwater or has become active and/orstaffed.If, during the period of coverage under this permit, the facility becomes qualified for theinactive and unstaffed exception and there are no industrial materials or activitiesexposed to stormwater, the permittee shall notify ADEQ of this change in the facility’snext benchmark monitoring report. Benchmark monitoring may be discontinued onceADEQ is notified, and the permittee signs the certification statement in Appendix B,Subsection 9 concerning the facility’s qualification for this special exception is preparedand signed.6.2.1.5 Exception to Monitoring Requirements for Ephemeral Waters.Facilities authorized for coverage under this permit that discharge to ephemeral waters arenot required to monitor for Total Suspended Solids (TSS) and turbidity as part of thebenchmark monitoring requirements when the parameters specify TSS and turbidity in thesector-specific section of Part 8. Monitoring for any remaining parameters in Part 8 may beperformed once each wet season, for a total of twice per year. The permittee is required tocollect at least two samples in a permit term, even if it extends beyond this one year period.Once the two samples have been collected, the permittee shall evaluate the data inaccordance with Part 6.2.1.3.Stormwater Discharges Associated with Industrial Activity 28

If the pollutant for which the waterbody is impaired is expressed in the formof an indicator or surrogate pollutant, the permittee shall monitor for that indicator orsurrogate pollutant. No monitoring is required when a waterbody’s biological communities areimpaired but no pollutant, including indicator or surrogate pollutants, is specified as causingthe impairment, or when a waterbody’s impairment is related to hydrologic modifications,impaired hydrology, or temperature.Stormwater Discharges Associated with Industrial Activity 29

Once the four (4) samples have been collected, ifthe pollutant for which the water is impaired is not detected above applicable water qualitystandards, the permittee may discontinue further monitoring for that pollutant, under thissection. The permittee shall keep records of this finding with the SWPPP. If the pollutant forwhich the water is impaired is found in the discharge above applicable water qualitystandards for any of the samples collected in the first year of sampling, the permittee shallcontinue monitoring twice during each wet season.Further, this monitoring requirement does not apply after one year if the pollutant for whichthe waterbody is impaired is not detected above natural background levels in the discharge,and the permittee documents, as required in Part 5.4, that this pollutant is not expected to bepresent above natural background levels in the discharge.If the pollutant for which the water is impaired is not present and not expected to be presentin the facility’s discharge, or it is present but it has been determined that the presence iscaused solely by natural background sources, the permittee shall include a notification to thiseffect in the first monitoring report, after which annual monitoring may be discontinued. Tosupport this determination, the following documentation must be submitted with the firstmonitoring report and kept with the SWPPP records: An explanation of why the presence of the pollutant causing the impairment in yourdischarge is not related to the activities at the facility; and Data and/or studies that tie the presence of the pollutant causing the impairment in thedischarge to natural background sources in the watershed.Discharges to impaired waters with an ADEQ approved TMDL.For stormwater discharges assigned a WLA in an approved TMDL, the facility shall monitorfor the pollutant for which the TMDL was written. Beginning in the first wet season followingthe facility’s date of discharge authorization, the permittee shall monitor twice per wet seasonat each outfall discharging stormwater to the impaired water with an approved TMDL.ADEQ’s authorization to discharge will include specifications on any additional pollutant(s) tomonitor.If the pollutant for which the water is impaired is not detected above the applicable WLA inthe TMDL after the four samples have been collected, the permittee may discontinue furthermonitoring, under this section. The permittee shall keep records of this finding onsite with theSWPPP.If the pollutant for which the water is impaired is found above the applicable WLA in theTMDL in the discharge for any of the samples collected in the first year of sampling, thepermittee shall continue monitoring twice during each wet season. Attainment of the WLA forSSC will be based on the median of four samples collected from four different measureablestorm events.6.2.4 Additional Monitoring Required by ADEQ.ADEQ may notify the permittee, in writing, of additional discharge monitoring required to ensureprotection of receiving water quality in cases where there is evidence that a pollutant is being dischargedthat is not being monitored for by the permittee and that the pollutant may be causing or contributing toexceedances of a water quality standard. Any such notice will provide an explanation of the reasons forthe monitoring, locations, and parameters to be monitored, frequency and period of monitoring, sampletypes, and reporting requirements.Stormwater Discharges Associated with Industrial Activity 30

Upset2. ADEQ may approve an anticipated bypass, after considering its adverse effects, if theDepartment determines that it will meet the three conditions listed above in this AppendixB, Subsection 20.d.a. Definition. Upset means an exceptional incident in which there is unintentional andtemporary noncompliance with technology based permit effluent limitations because offactors beyond your reasonable control. An upset does not include noncompliance to theextent caused by operational error, improperly designed treatment facilities, inadequatetreatment facilities, lack of preventive maintenance, or careless or improper operation.b. Effect of an upset. An upset constitutes an affirmative defense to an action brought fornoncompliance with such technology based permit effluent limitations if the requirements ofAppendix B, Subsection 21.c are met. No determination made during administrative review ofclaims that noncompliance was caused by upset, and before an action for noncompliance, isfinal administrative action subject to judicial review.c. Conditions necessary for a demonstration of upset. A permittee who wishes to establishthe affirmative defense of upset must demonstrate, through properly signed,contemporaneous operating logs, or other relevant evidence that:1 An upset occurred and that the permittee can identify the cause(s) of the upset;2 The permitted facility was at the time being properly operated;3 The permittee submitted notice of the upset as required in Appendix B, Subsection 12.d(iii); and4 The permittee complied with any remedial measures required under Appendix B,Subsection 4.d. Burden of proof. In any enforcement proceeding, the permittee, who is seeking toestablish the occurrence of an upset, has the burden of proof.G.

Non-Mining MSGP 2010 General PermitAppendix D. Calculating Hardness in Surface Waters Receiving Stormwater Discharges forHardness Dependent MetalsOverviewBenchmarks have been adjusted for six hardness-dependent metals (i.e., cadmium, copper, lead, nickel,silver, and zinc) to further ensure compliance with water quality standards and provide additionalprotection for endangered species and their critical habitat. For any sectors required to conductbenchmark samples for a hardness-dependent metal, ‘hardness ranges’ are included from whichbenchmark values are determined. To determine which hardness range to use, the permittee must collectdata on the hardness of the facility’s surface water(s) that receive discharges or the hardness of thedischarge itself based on the type of the receiving water body. Once the site-specific hardness data havebeen collected, the corresponding benchmark value for each metal is determined by comparing where thehardness data fall within 25 mg/L ranges, as shown in Table 1.Table 1.

You can obtain these coordinates throughgeographic information system tools, topographic maps, orADEQ’s web-based GIS mapping system at: http://gisweb.azdeq.gov/arcgis/emaps/?topic=impaired.For consistency, take the coordinates from the location ofyour facility’s stormwater outfall. Outfalls are locations where thestormwater exits the facility, including pipes, ditches, swales, andother structures that transport stormwater. If there is more thanone outfall present, provide the coordinates of the primary outfall(i.e., the outfall with the largest volume of stormwater dischargeassociated with industrial activity).4. Indicate if industrial stormwater discharges from your facility werepreviously covered by a NPDES or AZPDES permit.If the facility was covered by the 2000 MSGP, include the EPAtracking number or the ADEQ authorization number, whichever isapplicable. If the facility was covered under an AZPDES individualpermit, include that permit number.5. Indicate whether the facility is located on Indian Country Lands. Ifyou answered yes, DO NOT submit this NOI to ADEQ. TheDepartment does not have permitting authority on Indian CountyLands. You must coordinate with the U.S. EPA for permit coverageon Indian Country Land within Arizona.6. Provide the sector and subsector codes, and SIC or Activity Codesthat best describes the primary industrial activities performed byyour facility. Your primary industrial activity includes any activitiesperformed onsite that are (1) identified by the facility’s SIC code forwhich the facility is primarily engaged; and (2) included in thenarrative descriptions of 40 CFR 122.26(b)(14)(i), (iv), (v), or (vii)and (ix). See Appendix C of the MSGP for a complete list of SICcodes and Activity Codes. See the footnote in Appendix C, orTable 1, for how to determine the SIC code.Enter the area (in acres) of industrial activity at your facilitythat is exposed to stormwater.7. If your facility has co-located industrial activities that are notidentified as your primary industrial activity, identify the sector andsubsector codes, SIC or Activity Codes, and area (in acres) thatdescribe these other industrial activities. For a complete list ofsector and subsector codes, see Appendix C of the MSGP.Enter the area of industrial activity (by SIC or AC code) ofall co-located sites exposed to stormwater.8.

term (with approximate dates) in which the facility will be inactiveand unstaffed.Section D. Discharge Information1. Indicate whether stormwater from your facility will be discharged intoa municipal separate storm sewer system (MS4). An MS4 is aconveyance or system of conveyances, including roads withdrainage systems, municipal streets, catch basins, storm drains,curbs and gutters, ditches and man-made channels, owned oroperated by a state, city, town, county, district, association or otherpublic body, used to collect or convey stormwater.If you checked “yes,” identify the name of the MS4 operator. Alist of MS4 operators can be found at: http://www.azdeq.gov/environ/water/permits/stormwater.html#ms4.2. Receiving Water.a. Indicate the name(s) of the receiving water(s) into whichstormwater from your facility will discharge. The receiving watermay be a lake, stream, river, dry wash, wetland, or otherwaterbody, and may or may not be located adjacent to yourfacility.Stormwater from the facility may discharge directly to areceiving water or indirectly via a storm sewer system, an opendrain or ditch, or other conveyance structure. DO NOT list aman-made conveyance, such as a storm sewer system, as yourreceiving water. Indicate the first receiving water yourstormwater discharge enters. For example, if the dischargeenters a storm sewer system that empties into Trout Creek,which flows into Pine River, the receiving water is Trout Creekbecause it is the first waterbody the discharge will reach.Similarly, a discharge into a ditch that feeds Spring Creekshould be identified as “Spring Creek” since the ditch is amanmade conveyance.If the facility discharges into a municipal separate stormsewer system (MS4) you must identify the waterbody into whichthat portion of the storm sewer discharges. That informationshould be readily available from the operator of the MS4.b. Indicate whether the facility discharges within 2.5 miles of alake, river, stream segment, wash, etc. that is classified as animpaired or outstanding Arizona water (OAW) under the“2006/2008 303(d) List of Impaired and Not Attaining Waters”(http://www.azdeq.gov/environ/water/assessment/download/2008/2006_2008.pdf).c. Answer the following questions only if you answered “yes” toItem D.2.b.i. Provide the pollutants listed as causing the impairment inthe water identified in Item D.2.b.ii. Out of the pollutant(s) that you identified in Item D.2.c.1,indicate which pollutants you believe will be present in thedischarge. If you do not expect any of these pollutants tobe in the discharge, then enter “none.”iii. Indicate the pollutants that have a Total Maximum DailyLoad (TMDL) for the impaired stream segment that youidentified in Item D.2.c.2. (See the 2006/2008 list ofimpaired waters at: http://www.azdeq.gov/environ/water/assessment/download/2008/2006_2008.pdf.)3. Water Quality StandardsIf you selected “yes” in Item C.4 you are considered an existingdischarger and may skip this question.If you selected “no” in Item C.4 indicating that stormwaterdischarges from your facility have not been previously coveredunder an NPDES or AZPDES permit, you are considered a newdischarger and must answer this question.a. If you are a new discharger, any discharge into an impairedwater is not automatically eligible for coverage under theMSGP. (See Part 1.1.4.5 of the permit.)b. If you selected “yes” in Item D.3.b indicating that the receivingwater has been designated as an outstanding Arizona water(OAW) under A.A.C. R18-11-112 you are not eligible forcoverage under the MSGP. (See Part 1.1.4.6 of the permit.)4. Effluent Limitation Guidelines and Sector-Specific Requirementsa. Depending on your industrial activities, your facility may besubject to effluent limitation guidelines that include additionaleffluent limits and monitoring requirements for your facility.Review the requirements, described in Part 2.2.1 of theMSGP, and check any appropriate boxes on the NOI form.b. For Sector S facilities (Air Transportation), indicate whetheryou anticipate that the entire airport facility will use more than100,000 gallons of glycol-based deicing/anti-icing chemicalsand/or 100 tons or more of urea on an average annual basis.If so, additional effluent limits and monitoring conditions applyto your discharge (See Part 8, Sector S of the MSGP).Section E. Stormwater Pollution Prevention Plan (SWPPP)Identify the name, telephone number and e-mail address of theperson who will serve as a contact for ADEQ on issues associated withstormwater management at your facility. This person should be able toanswer questions related to stormwater discharges, the SWPPP, andother matters related to stormwater permit coverage, or haveimmediate access to individuals with that knowledge.

October 2011RE:Alternative Industrial Stormwater Visual Assessment Requirements forSector S (Air Transportation) FacilitiesDear Sector S Facility Owner/Operator:As airports have worked to implement Multi-Sector General Permit (MSGP 2010) requirements, theArizona Department of Environmental Quality (ADEQ) has become aware of the practical challenge someairports may have implementing visual assessment monitoring requirements where the airport authority isworking with multiple tentants/co-permittees to implement the permit. The department is providing thisoptional alternative approach to visual assessment monitoring to assist the airport and its tenants/copermitteesin meeting permitting requirements by providing flexibility to visual assessment monitoring.BackgroundAirports and tenants that are engaged in industrial activity that results in a stormwater discharge mustobtain AZPDES permit coverage by each submitting a separate Notice of Intent (NOI), regardless ofwhether the tenants are co-permittees (see Federal Register, Volume 60, Number 189, Friday,September 29, 1995, page 50998). Each NOI must include information specific to the facility beingpermitted, including the name and address of the facility, and the latitude and longitude of the facility (seeArizona Administrative Code R18-9-C901(D)).The MSGP 2010 requires permittees (including co-permittees) to conduct visual assessment monitoringfour times per year (twice each in the winter and summer wet seasons). The intended purpose of thevisual assessment monitoring is to provide a useful and inexpensive means for permittees to evaluate theeffectiveness of their stormwater pollution control measures. It is important to note that a co-permittee isa permittee to an AZPDES permit that is only responsible for AZPDES permit conditions relating to thedischarge for which it is an operator (40 CFR 122.26(b)(1)).Therefore, under the MSGP 2010, permittees/co-permittees are required to conduct visual assessment atthe outfalls from their permitted facility. U.S. EPA has provided clarification of outfall as follows:Q6A6What is the definition of “outfall”In general, an industrial outfall is the point where stormwater associated with industrialactivity discharges to waters of the U.S. or a municipal separate storm sewer system(MS4). An outfall does not include conveyances, pipes, or tunnels connecting segmentsof the same system. Sometimes the actual receiving waterbody may be some distanceaway from the industrial site, (for example, when a facility’s stormwater flows offsite to anoutfall via a conveyance that is not part of the MS4, sometimes being commingled withdischarges from other facilities, roadways, etc. along the way). In such cases, thefacility’s outfall is considered to be the location where the discharges leave the industrialsite, and the conveyance is considered to be a tributary to a receiving water. (Questionsand Answers Regarding the Multi-Sector General Permit for StormwaterSouthern Regional Office400 West Congress Street • Suite 433 • Tucson, AZ 85701(520) 628-6733Printed on recycled paper

Page 2 of 3Discharges Associated with Industrial Activity, as updated August 14, 2009, U.S.Environmental Protection Agency)Conducting visual assessment precisely where the stormwater leaves a permitted facility provides theoperator the advantage of evaluating the stormwater before it commingles with stormwater from otherfacilities. Visual assessment conducted in this way also gives the operator an immediate opportunity tomitigate problems in the event pollutants are discovered, and is therefore an important component inmeeting the requirements and objectives of MSGP 2010.However, based on discussions between ADEQ and various airports located in Arizona, some airportsmay have real and practical considerations that prevent them from conducting visual assessments in thismanner. Specifically, hazards inherent to airport operations may preclude visual assessments of each“outfall” of multiple tenants/co-permittees during storm events.Optional Sector S Visual Assessment Alternative RequirementsThe department will allow, at the option of the airport, visual assessment monitoring to be conducted at“main outfalls” in lieu of visual assessment monitoring at each tenant facility. For the purpose of this visualassessment alternative at Sector S facilities, “main outfalls” are those outfalls that discharge industrialstormwater collected from two (2) or more regulated tenants and discharge directly to a receiving water ora municipal separate storm sewer system.The optional Sector S Visual Assessment Alternative has the following requirements:1) Visual assessment must be conducted two (2) times per wet season (see MSGP section 4.2) ateach of the “main outfall(s).” As each outfall discharges stormwater collected from an area of theairport occupied by a number of tenants, visual assessment at each of the “main outfalls” willprovide a nearly equivalent assessment of each tenant’s facility and stormwater quality – as isintended by the MSGP 2010.If this optional visual assessment approach is selected, the airport and its co-permittees cannotmake use of the substantially identical outfall provision of the MSGP 2010 permit for outfalls thatreceive industrial stormwater combined from two (2) or more permitted facilities. The airportretains the option to use of the substantially identical outfall provision for those outfalls that do notreceive combined industrial stormwater discharges from co-permittee facilities, provided permitrequirements are met (see permit section 5.1.5.2 and fact sheet section IX.A.1)2) The stormwater pollution prevention plan (SWPPP) must include a detailed process for identifyingpollutant sources. The process must take into consideration how the pollution prevention teamwill trace a pollutant discovered in a visual assessment sample from a “main outfall” back to aparticular tenant or source. The process must include, at a minimum, the following:a) Identification of personnel (by name and/or title) involved in visual assessmentmonitoring:b) Actions to be taken to identify pollutant source(s);c) Timeframes for actions to identify pollutants source(s), notifying tenant(s), andcorrecting control measure deficiencies; andd) Documentation of actions and outcome.3) For the first two years of the permit (and thereafter if requested by ADEQ), the airport authorityshall submit documentation of visual assessment activities to the department no later than June30 of each year. The documentation must include the information specified in section 4.2.2 of thepermit as well as the following:

Page 3 of 3a) Physical indicator parameters listed in section 4.2.1; andb) The action step(s), source(s), and outcome for each follow up investigation.While not required, the department encourages airport tenants to participate in visual assessmentmonitoring activities to help foster awareness and involvement in their stormwater program activities andresponsibilities.If information becomes available to the department that demonstrates this optional alternative approach isineffective at evaluating control measures, the department may withdraw this alternative approach eitherin whole or on a site by site basis.ConclusionBased on discussions with various Arizona airports and information currently available to the department,ADEQ believes that this optional visual assessment monitoring approach at “main outfalls” together withthe above requirements serve as an equivalent and protective measure to evaluate the effectiveness ofstormwater pollution control measures at airports.If you have any questions about visual assessment requirements, the alternative visual assessmentrequirements for Sector S facilities described in this letter, or other questions about the AZPDES programplease contact Christopher Henninger at henninger.christopher@azdeq.gov or (602) 771-4508.

INTRODUCTIONIn 1972, Congress passed into law the Clean Water Act (CWA) amendments to remedyfederal water pollution on a national basis. The amended CWA absolutely prohibits thedischarge of any pollutant into waters of the United States via the public storm drainsystem unless the discharge is made in accordance with a National Pollutant DischargeElimination System (NPDES) Permit. In Arizona, NPDES Permits are made available bythe United States Environmental Protection Agency (EPA), setting forth conditions underwhich discharges may be made.The EPA has issued a NPDES Permit to the City of Phoenix, as a whole, under theauthority of the CWA. In addition, the EPA has issued a NPDES Storm Water Multi-Sector General Permit on a national basis to cover a wide variety of industrial activities.Included in the numerous industry-specific sections of the Multi-Sector NPDES Permit isAir Transportation, and associated activities, imposing obligations and responsibilitiesupon the City’s Aviation Department, its tenants and permittees.The Phoenix City Council has also authorized the City Manager or his designee toregulate the use of the public storm discharge system. Phoenix City Code Ch. 32C wasadopted to reduce to the maximum extent practicable, the addition of pollutants to stormwater to prevent violations of the City’s NPDES permit or applicable water qualitystandards.In 1994, the City of Phoenix Department of Street Transportation adopted a policyentitled “Storm Water Monitoring Enforcement Action” in order to comply with theCity’s NPDES Permit and Phoenix City Code Ch. 32C. Likewise, the City of PhoenixAviation Department has adopted the Aviation Department Storm Water EnforcementPolicy in order to save tenants the time and expense of applying for an individual NPDESPermit and to encourage the development of airport wide best management practices toprevent pollution of the airport’s storm water drainage system.Following is the Aviation Department Storm Water Enforcement Policy, which isapplicable to Phoenix Sky Harbor International, Phoenix Goodyear Airport, and DeerValley Airport. It applies to all airport users whether or not they are co-permitteeson the airports’ NPDES Permit.Revised 4/22/99C:\Documents and Settings\pucketthk\Local Settings\Temporary Internet Files\Content.Outlook\OVKL36RZ\SW Enforcement Policy.docii

SECTION ICITY OF PHOENIX AVIATION DEPARTMENTSTORM WATER DISCHARGE ENFORCEMENT PROCEDURESEffective Date: March 1, 1997A. PURPOSE – These procedures explain the possible actions that the City ofPhoenix Aviation Department may use to prevent pollution of the waters of theUnited States (more specifically the Salt River, Agua Fria tributaries, or CaveCreek drainage) through the municipal storm drain system for airport drainage.The Aviation Department believes that a policy specific for its airports will betterensure that all enforcement actions will be handled with fairness, and withconsideration for airport operations. While Sections I and II of this policycontemplate actions that will be taken in ascending order, emergency situations orserious violations may call for immediate sanctions and by passing one or more ofthe less stringent actions.B. INITIAL SELF-REPORTING POLICY/TENANT RESPONSIBILITY – Alltenants and permittees (collectively “Tenants”) shall report spills, releases anddischarges of pollutants, or releases threatening the storm drain systemimmediately to the Aviation Department. Airport Tenants who self reportdemonstrate good faith efforts to comply with this policy and such action will beconsidered as a mitigating factor in the penalty process. Generally, the AviationDepartment will not initiate formal enforcement action on a self-reported,unavoidable discharge under circumstances when it is unreasonable to preventsuch discharge, the discharge amount is minimal and poses no risk to humanhealth or the environment.Although Phoenix City Code Section 4-109 requires any person who spills apollutant on airport property to immediately remove the pollutant, Section 4-12 confers ultimate responsibility for all damages to airport property uponan airport Tenant, whether caused by the Tenant’s employees or itscontractor.C. ENFORCEMENT CRITERIA – When a violation of the City Storm WaterOrdinance (Chapter 32C) or other applicable environmental regulation isidentified, enforcement actions can be taken. The enforcement action (includingthe amount of any monetary penalties) will depend upon several factors:1) Severity of the violation; the duration, quality and quantity of pollutants,and effect on public safety and the environment.2) The violator’s knowledge (either negligent or intentional) of the regulationbeing violated.3) Any history of violations, including enforcement actions involving thesite, business, or individual.-1-Revised 4/22/99C:\Documents and Settings\pucketthk\Local Settings\Temporary Internet Files\Content.Outlook\OVKL36RZ\SW Enforcement Policy.doc

4) The effect of the enforcement action to act as a deterrent of similarviolations in the regulated community.D. LEVELS OF ENFORCEMENT – Several levels of enforcement actions areavailable to the City. The typical types of enforcement actions are listed below inincreasing order of severity.E. INFORMAL ENFORCEMENT ACTIONS – Each violation will bedocumented with a written Notice of Violation (NOV) issued by on-site airportpersonnel. The NOV will require the violating facility to report the incident to theAviation Environmental Section, 273-8861, within 24 hours of receipt of theNOV. Weekend reporting can be left on the Aviation Department answeringmachine at the same phone number.In addition, within fifteen (15) calendar days of receipt of the NOV, the violatingfacility must submit a detailed written report to the Aviation EnvironmentalSection explaining how the incident took place and the corrective active taken toprevent future occurrences. If the violation was caused by a tenant’s contractor,the contractor shall send a copy of the report the tenant and the tenant is alsorequired to submit a detailed written report. At a minimum, this report mustaddress the following:1) A summary of the name and positions of persons involved in the incident;equipment involved; and how the incident occurred, including time, placeand materials and quantity released.2) A detailed description of the investigation and conclusions.3) How cleanup of released materials was performed, including equipmentand materials used in the cleanup, and how waste was disposed.4) Corrective action your company has taken or plans to take and the time inwhich all corrective action will be completed.

the best of my knowledge and belief, true, accurate, and complete. I amaware that there are significant penalties for submitting false information,including the possibility of fine and imprisonment for knowingviolations.”Failure to comply with these requirements will subject the violator to futureenforcement actions. Compliance with this request does not preclude the Cityfrom taking additional enforcement action under its authority: Chapter 32C of thePhoenix City Code.If additional time is required in order to complete the written report, a writtenrequest for an extension must be submitted by the violating facility in time forCity approval prior to the due date.F. AIRPORT TENANT COMPLIANCE1) The Aviation Environmental Section shall notify the Deputy Director ofBusiness and Properties (the “Deputy”) for further enforcement action ifany of the following occurs:(a) An airport tenant or permittee (collectively “Tenant”) has receivedtwo NOV’s within a twenty-four (24) month period; or(b) The Tenant has failed to timely provide the detailed written reportas required under Section I of this policy; or(c) The Tenant fails to comply with the corrective actions that theTenant submitted under Section I.(d) The Tenant’s failure to follow the airport’s best managementpractices, or upon recommendation of the Aviation DepartmentEnvironmental Section.2) Tenant/NPDES Co-permittee - The Aviation Department allowed eligibleTenants to become co-permittees on the City of Phoenix NationalPollutant Discharge Elimination System Storm Water Multi-SectorGeneral Permit for Industrial Activities (the “NPDES Permit”) as meansto save eligible Tenants substantial costs of obtaining individual NPDESpermits. Each Tenant who has joined the City as a Co-permittee (“ aNPDES Co-permittee”) has signed an agreement that sets forth the termsand conditions for being retained on the NPDES permit (the “NPDESAmendment”).In the event that Section I(F)(1)(a), (b) or (c) of this Policy applies to anNPDES Co-permittee, the Deputy shall notify the tenant/NPDES Copermittee’sChief Operating Officer or designee, and shall establish acorrective action plan pursuant to the procedures that have been agreed toby the parties to achieve compliance with the NPDES Permit and Chapter32C.Revised 4/22/99 -3-

If a NPDES Co-permittee fails to comply with a corrective action plan,including best management practices or other requirements, such noncompliancemay be deemed to be a material breach of the tenancyagreement or permit and may provide grounds to terminate the tenant’sNPDES Co-permittee status and/or its ability to do business on airportproperty.3) Tenant/Non-NPDES Co-Permittees - If a Tenant who has not signed aNPDES Agreement fails to comply with the NPDES Permit or Chapter32C, the Environmental Section may refer the Tenant to the appropriateDeputy for further enforcement action or termination of the Tenant’spermission to do business on airport property. All airport users should beaware that any industrial discharge or polluted runoff to the storm drain isa violation of federal law, unless it is specifically authorized by a NPDESpermit.4) The Provisions of this Subsection I(F) shall be in addition to such otherremedies as are provided by this Policy or otherwise provided by law.G. FORMAL ENFORCEMENT ACTIONSCompliance Status Review Meeting – In situations where prior enforcementactions have failed to produce compliance or a reasonable commitment to attaincompliance by an established deadline, a “Notice of Compliance Status ReviewMeeting” letter will be issued to the violator, and City representatives. Themeeting will be held to present evidence establishing the non-compliance andrequesting the violator to “show cause” why the City should not engage in moreserious enforcement actions. At the meeting, the City will review the violations,tenant’s responses to the violations, explain the City enforcement policies, andidentify any potential penalties for non-compliance. An attempt will be made toreach an agreement on the type of compliance activity required. The terms of thisAgreement will be contained in a Storm Water Settlement Agreement.

SECTION IISTORM WATER DISCHARGE CIVIL PENALTY POLICYA. INTRODUCTION – The City of Phoenix (City) has developed a Storm WaterCivil Penalty Policy (SCPP) for use City-wide that describes how the City willcalculate civil penalties for instances of noncompliance with Chapter 32C of thePhoenix City Code.

PURPOSE - The purpose of the SCPP is to (1) deter potential violators of theCity Storm Water Ordinance (Chapter 32C); (2) provide fair and equitabletreatment to the community, (3) facilitate swift resolution of environmentalproblems; (4) deter future noncompliance by providing an incentive to remain incompliance; (5) remove the economic benefit a person or business gains overothers by not complying with the law; and (6) use in potential settlementdiscussions with violators.C. COSTS – Any costs associated with the violator(s) (such as sampling, analysis,investigation, surveillance) and any harm done to the environment or damage toCity property is not included in the amount of the calculated penalty. Rather,these costs are separate and distinct from civil penalties and can be recovered inadditional to any monetary penalty.D. CIVIL PENALTY AUTHORITY – Civil penalties are authorized under Section32C-106(e) of the Phoenix City Code. The maximum civil penalty amount thatcan be imposed if Twenty Five Hundred Dollars ($25j00) per day for eachviolation. Each day of continuing violation is a separate civil offense.E.
