Resources for the Construction Industry
Below are questions frequently asked about storm water pollution prevent for construction sites.
Sites that will disturb one or more acres of area or are less than one acre if the project is part of a larger common plan of development.
Storm water discharges and runoff associated with construction sites can be a major contributor of pollutants to an urban storm sewer system, a wash or other waterways. Pollutants associated with construction activity may include, but are not limited to sediment, phosphorus, nitrogen, solvents, petroleum products, solid waste, paints, asphalt, concrete, sealants, pesticides, etc.
You will be required to develop a Storm water Pollution Prevention Plan (SWPPP) and submit a completed Notice of Intent (NOI) to the Arizona Department of Environmental Quality (ADEQ) for permit coverage. Other requirements may be necessary if working within ¼ mile of an impaired or unique receiving water.
- Maintain a copy of the SWPPP on site
- Post Authorization Number near site entrance
- Implement and maintain Best Management Practices (BMP's) throughout the project
- Incorporate a combination of BMP's to address erosion and sediment control and the control of wastes and other construction site pollutants
- Conduct site inspections per the frequency detailed in the SWPPP
- Promptly correct deficiencies found during inspections or field observations as soon as possible
- Repair and maintain BMP's when found to be ineffective or in need of repair
- Update the SWPPP to reflect changes or modifications relative to current site conditions
- Submit a Notice of Termination (NOT) to ADEQ upon final site stabilization
