Title: Companies Settle Alleged Violations of Regulations to Protect Stormwater Runoff.

Summary:

The US Environmental Protection Agency (EPA) has entered into an administrative consent agreement with TPWR Developer, LLC, CBG Building Company, and Bowman Consulting regarding alleged violations of regulations designed to protect stormwater runoff. The companies have agreed to pay a $27,000 penalty and implement a Supplemental Environmental Project (SEP) to settle the violations. The SEP will be performed at the Walter Reed Army Hospital construction site in Washington, D.C., which has experienced stormwater runoff containing sediment, oil, and grease. The companies will implement measures to reduce pollutants and obtain a permit under the National Pollutant Discharge Elimination System (NPDES). In addition, the companies will spend at least $40,000 to protect the endangered Hay's Spring amphipod in Rock Creek Park, Washington D.C. The SEP will involve habitat restoration, revegetation, and tree planting with oversight from the National Park Service.
