Construction Site Management POLLUTANTS ADDRESSED: Sediments, Nutrients and Organics, Heavy Metals

DESCRIPTION: Construction site management involves a set of planning and implementation activities which must be put into operation before, during, and after a construction project is carried out. Guidance on the development of an appropriate plan, known as a “stormwater pollution prevention plan” (SWPPP), can be obtained from the US EPA document cited below. The ultimate goal of any SWPPP is to protect rivers, lakes, wetlands, and coastal waters that could be affected by the construction project. Practices include appropriate handling of pollutants and special or hazardous wastes which could be released. Effective erosion control measures should be implemented throughout the construction site.

ADDITIONAL BENEFITS: Educated workers not likely to mishandle or misuse equipment or hazardous wastes. POTENTIAL TREATMENT AREAS: Construction sites Developed lands ALTERNATIVE MANAGEMENT MEASURES: Straw bale barrier Silt fence Erosion control fabric Detention basin

LOAD REDUCTION MECHANISM: Organics/Nutrients Management- Oversight by managers to make sure precautions is followed. Sediment Reduction- Oversight by managers to make sure precautions is followed. Heavy Metal Reduction- Oversight by managers to make sure precautions is followed.

PERMITTING REQUIREMENTS: A general construction and/or grading permit will be required. Contact county regional flood control district. SOURCES OF ADDITIONAL INFORMATION: ADEQ's stormwater construction permits page for additional information: http://www.azdeq.gov/environ/water/permits/stormwatr .html.

PLANNING AND IMPLEMENTATION: Erosion Control and Minimizing the Impact of Construction: 1. Minimize disturbed area and protect natural features and soil 2. Phase construction activity 3. Control stormwater flowing onto and through the project 4. Stabilize soils promptly 5. Protect slopes Sediment Controls: 1. Protect storm drain inlets 2. Establish perimeter controls 3. Retain sediment on-site and control dewatering practices 4. Establish stabilized construction exits 5. Inspect and maintain controls
