Source Control BMPs Chapter 5 • Prevent or reduce the amount of polluted stormwater generated by municipal operations; • Educate employees to incorporate pollution prevention and good housekeeping practices into municipal operations; and • Identify BMPs and measurable goals for the prevention or reduction of the amount of polluted stormwater that is generated by municipal operations. Developing an effective municipal pollution prevention and good housekeeping program involves implementing a program that 1) is specifically designed for a community, taking into consideration how information is communicated and how training is provided and received, and 2) incorporates sound standard practices for various operations. Many communities nationally and in the metro Denver area have developed such standard operating procedures. The Fact Sheets provided in this chapter may be used to develop such procedures or to supplement existing procedures. Development of a program that is specifically tailored to a community should begin with evaluation of the following questions (Center for Watershed Protection 2008): Examples of Stormwater "Hotspots" • Fleet storage areas • Solid waste facilities • Wastewater treatment plants • Composting facilities • Nurseries and garden centers • Restaurants • Industrial rooftops • Recycling facilities • Maintenance facilities • Gas stations • Fast-food drive-thru areas • Airports 1. What municipal operations are conducted within the community? 2. What stormwater pollutants are associated with the operations? 3. Who is responsible for managing each of the operations? 4. What is the primary pollutant of concern in the subwatershed? 5. Which of the operations has the greatest influence on water quality and should be the focus of the community's pollution prevention/good housekeeping efforts? 6. What specific pollution prevention/good housekeeping practices should be implemented to improve the operations? 7. How much will the pollution prevention/good housekeeping practices cost? 8. Who will be responsible for implementing the pollution prevention/good housekeeping practices? 9. How will progress made in pollution prevention/good housekeeping be evaluated? Developing a Municipal Program Urban Subwatershed Restoration Series Manual 9: Municipal Pollution Prevents/Good Housekeeping Practices prepared by The Center for Watershed Protection (2008), outlines a detailed approach for developing a municipal pollution prevention/good housekeeping program.

Chapter 5 Source Control BMPs Table 5-2. Polluting Activities Associated With Common Hotspot Operations (Source: Center for Watershed Protection 2005) Polluting Activities Associated With Common Hotspot Operations Hotspot Operation Vehicle Operations Outdoor Materials Waste Management Physical Plant Maintenance Turf and Landscaping Polluting Activity • Improper disposal of fluids down shop and storm drains • Spilled fuel, leaks and drips from wrecked vehicles • Hosing of outdoor work areas • Wash water from cleaning • Uncovered outdoor storage of liquids/oils/batteries spills • Pollutant wash-off from parking lot • Spills at loading areas • Hosing/washing of loading areas into shop or storm drains • Wash-off of uncovered bulk materials and liquids stored outside • Leaks and spills • Spills and leaks of liquid • Dumping into storm drains • Leaking dumpsters • Dumpster juice • Wash-off of dumpster spillage • Discharges from power washing and steam cleaning • Wash-off of fine particles from painting/sandblasting operations • Rinse water and wash water discharges during cleanup • Temporary outdoor storage • Runoff from degreasing and re-surfacing • Non-target irrigation • Runoff of nutrients and pesticides • Deposition and subsequent wash-off of soil and organic matter on impervious surfaces • Improper rinsing of fertilizer/pesticide applicators 3.2 Commercial and Industrial Operations Commercial and industrial source controls focus primarily on reducing exposure of materials to rainfall and runoff and preventing non-stormwater discharges to storm sewers. Check federal and state requirements for obtaining and complying with stormwater discharge permits. The following BMP Fact Sheets are targeted to commercial and industrial operations: • S-1 Covering Outdoor Storage & Handling Areas • S-2 Spill Prevention Containment and Control • S-5 Good Housekeeping November 2010 Urban Drainage and Flood Control District 5-5 Urban Storm Drainage Criteria Manual Volume 3
