Storm water runoff is generated from rain and snowmelt events that flow over land or impervious surfaces, such as paved streets, parking lots, and building rooftops, and does not soak into the ground. The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment that can harm our rivers, streams, lakes, and coastal waters.
storm water pollution prevention plan (SWPPP)
The subject property was regulated under the Georgia EPD’s storm water permit, requiring a Storm Water Pollution Prevention Plan (SWPPP) to ensure that downstream sites and water bodies were not being polluted by runoff from the site.
bioretention storm water filter
The subject property had aluminum in their soil from site activities that took place under the prior owner. This aluminum was becoming suspended in the storm water during heavy rainfall events and exiting the subject property at concentrations greater than the state recommended benchmark.
detention basin design-build
The facility was discharging high amounts of total suspended solids (TSS) into the storm water. These high amounts of TSS exceeded the allowable amounts stated in the NPDES Storm Water Permit for Discharges Associated with Industrial Activity.
