Get Serious About Storm Water

How to handle storm water runoff from construction sites has been one focus of the Environmental Protection Agency (EPA) for years. The EPA's goal is simple: to improve water quality by reducing pollutants in stormwater discharges. Although construction sites are not the only source of pollutants, they are receiving significant attention from the EPA, especially in more recent years. The agency has declared that from 2008 to 2010 it will pay close attention to three sectors — home building construction is one — to make sure they properly follow storm water regulations.

Why is stormwater runoff bad?

Imagine what happens when spilled oil, an overflowing Dumpster, loose excavated soil and open bags of concrete are on a job site during a rainstorm. Water that is not absorbed is picked up by the ground. The pollutants are transported to one of two places: either directly into a body of water or into the storm drain system, which eventually discharges into a body of water. If the runoff is polluted, it can damage the environment, including the water used for boating, swimming and drinking.

Best Management Practices

According to the EPA, the best approach to managing storm water on construction sites is by using self-designed Stormwater Pollution Prevention Plans (SWPPPs). These plans, designed by the home builder, are based on best management practices. Best management practices are measures or practices implemented on a construction site to control or prevent pollution from entering bodies of water. They may take the form of a process, activity or physical structure. In order to function properly, the systems must be installed correctly, inspected according to the SWPPP and maintained in accordance with the SWPPP. Doing so will help construction sites protect water quality and remain in compliance with storm water regulations. See the diagram below for ideas.
