Stormwater Pollution Prevention Plan - Phoenix Sky Harbor ...

Section 4 - Summary of Potential Pollutant
Sources
4.1 Activities in the Area
MSGP-2010 Part 5.1.3.1 requires the SWPPP to identify each area where industrial
materials or activities are exposed to stormwater with the potential to discharge and
areas from which allowable non-stormwater discharges are released. MSGP-2010 Part
8.S.5.2 requires consideration of pollutant sources in areas of airports where specific
activities take place. The following activities performed at PHX have the potential to
impact stormwater quality:
• Aircraft, Ground Vehicle and Equipment(AVE) Maintenance
• Aircraft, Ground Vehicle and Equipment Cleaning
• Aircraft, Ground Vehicle and Equipment Storage
• Material Storage Areas
• Airport Fuel System and Fueling Areas
• Building and Grounds Maintenance
• Aircraft Deicing
Figure 2 identify the specific areas where industrial materials or activities may be
exposed to stormwater. In some instances, the chemicals are stored indoors, but may be
transferred or activities may be conducted outdoors utilizing the chemicals. The CMs
for each activity are provided in Attachment 3.
MSGP-2010, Part 8.S.5.2 specifically requires that the potential pollutant sources from
the following activities be identified: aircraft, runway, ground vehicle and equipment
maintenance and cleaning; and aircraft and runway deicing operations (including apron
and centralized aircraft deicing stations, runways, taxiways and ramps). Table 4.1
identifies the industrial activities conducted by each co-permittee. The activities with
the potential to discharge pollutants to stormwater are described below.
4.1.1 Aircraft, Ground Vehicle & Equipment Maintenance
The majority of co-permittees maintain aircraft, equipment and/or vehicles.
Maintenance activities are performed both indoors and outdoors. The rental car
companies at the Rental Car Center (RCC) off the airport at a facility west of PHX
conduct light vehicle maintenance. While these rental car companies are not formally
co-permittees, as tenants on airport property, they are held responsible and inspected
for compliance with the requirements of this SWPPP. In addition, there are designated
areas at PHX for the storage and maintenance of ground support equipment (GSE).
Airport maintenance activities commonly involve the use of lubricating oils, hydraulic
oils, solvents, lavatory waste, used batteries, paint, and other cleaning products. Small
