Reducing Storm Water Pollution During Construction
Sediment PollutionConstruction runoff from rain storms picks up pollutants like sediment, oil and grease, fertilizers like nitrogen and phosphorus, and other chemicals and carries them into storm drains or directly into water bodies.

The construction process also disturbs the vegetative cover. This allows for the rapid erosion of the soil which causes increased sediment inflows into the adjoining streams. Too much sediment in a water body can cloud the water and make it difficult or impossible for aquatic plants to receive the sunlight they need to grow. Excess sediment also smothers aquatic habitat and clogs fish gills.

Simple erosion control and siltation control measures can prevent these situations from occurring. For this reason the City of Sand Springs has a siltation ordinance that makes it illegal for contractors for cause excessive siltation. Federal law also requires any development that disturbs over one acre of vegetative cover obtain a special permit. To download a permit application go to: www.epa.gov/npdes/stormwater/cgp.
