ASI Highway 90 Mining Pit is a stormwater outfall located at 12840 Highway 90 in Loxley, Baldwin County, Alabama. This facility manages stormwater runoff from a mining operation (NAICS 212321) and is classified as an industrial stormwater outfall. As a small-scale facility in the sector, it plays a role in controlling discharge from the site to local waterways. The facility operates under the US Clean Water Act and is subject to NPDES permitting requirements for industrial stormwater discharges.

The outfall likely requires a Multi-Sector General Permit (MSGP) or an individual permit, with monitoring and best management practices to control pollutants. Located in a coastal county near Mobile Bay, the outfall's discharge may affect sensitive aquatic ecosystems. Proper stormwater management at mining sites is critical to prevent sediment, metals, and other pollutants from impairing water quality. The facility's operational status indicates ongoing compliance with regulatory obligations.

The facility is situated in Baldwin County, Alabama, a coastal region with numerous water bodies including Mobile Bay and the Gulf of Mexico. Mining operations can generate stormwater runoff containing sediment, heavy metals, and other pollutants. Discharges from this outfall may impact local streams and ultimately the Mobile Bay estuary, which supports diverse aquatic life and recreational activities. Regulatory oversight under the Clean Water Act aims to minimize such impacts through permit conditions and monitoring.
