TULLIS BORROW PIT Stormwater Outfall in Gadsden, Alabama

TULLIS BORROW PIT is a stormwater outfall located in Gadsden, Alabama, United States. It is situated at Yates Road at Tabor Road and serves the local urban catchment in Etowah County. As a stormwater outfall, it is part of the infrastructure that manages runoff from the surrounding area, which includes industrial activities related to NAICS codes 212321 (Construction Sand and Gravel Mining) and 212399 (Other Nonmetallic Mineral Mining and Quarrying). The facility operates under the regulatory framework of the US Clean Water Act, specifically the National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permits. As a Phase II small MS4, it is subject to requirements for stormwater management, including pollution prevention, public education, and illicit discharge detection. The outfall discharges stormwater into local water bodies, which may be subject to Total Maximum Daily Load (TMDL) requirements for pollutants. Environmental significance lies in its role in managing stormwater runoff from an area with mining and quarrying activities, which can contribute sediment and other pollutants. Proper operation helps protect downstream water quality in the Coosa River basin. The facility's location in Gadsden, a city with mixed urban and industrial land use, underscores the importance of stormwater controls to mitigate flooding and water quality impacts.

The outfall is located in the Coosa River basin, which supports diverse aquatic ecosystems. Stormwater runoff from urban and industrial areas in Gadsden can carry pollutants such as sediment, heavy metals, and nutrients. The facility's discharge may affect water quality in receiving streams, particularly during heavy rainfall events. Regulatory oversight under the NPDES MS4 program aims to minimize these impacts through best management practices.
