Ketchum Pit Stormwater Outfall, Troy, Alabama | United States

Ketchum Pit is a stormwater outfall located in Troy, Pike County, Alabama, United States. It operates as a point of discharge for stormwater runoff, managed under the US EPA NPDES MS4 permit system, which regulates municipal separate storm sewer systems to control pollution. The facility is classified as a stormwater outfall, a common infrastructure component in urban and industrial areas for conveying runoff to receiving waters. As a stormwater outfall, Ketchum Pit is subject to the Clean Water Act and Alabama's water quality standards. The facility's NAICS code (212321) indicates its association with construction sand and gravel mining, suggesting the outfall may serve an industrial or mining catchment. Stormwater outfalls in such contexts often require permits to ensure discharges do not violate water quality criteria, particularly for sediment and other pollutants. The environmental significance of Ketchum Pit lies in its role in managing stormwater runoff from its catchment area. Proper operation and maintenance of outfalls like this are critical to prevent erosion, flooding, and pollution of downstream water bodies. In Alabama, stormwater management is increasingly important due to the state's vulnerability to heavy rainfall events and the need to protect aquatic ecosystems.

The Ketchum Pit stormwater outfall discharges into a receiving water body that may be sensitive to urban and industrial runoff. In Alabama, stormwater runoff can carry pollutants such as sediment, nutrients, and heavy metals, which can impair water quality and harm aquatic life. The facility's location in Pike County, a region with mixed agricultural and industrial land use, underscores the importance of effective stormwater management to protect local streams and rivers from degradation.
