Abstract |
These TMDLs were developed for: (1) the unnamed tributary to Brush Run; and (2) a portion of Brush Run, from its headwaters down to 0.9 miles from the confluence with Chartiers Creek, above the discharge point of Peters Township wastewater treatment plant. Brush Run is a tributary to Chartiers Creek (State Water Plan Subbasin 20F - Ohio River). The watershed is located in Allegheny and Washington Counties in western Pennsylvania. Portions of the Peters, Upper Saint Clair and Bethel Park townships form the watershed. The towns of Thompsonville and McMurray are located in this watershed. The entire Brush Run watershed falls within the Pittsburgh urbanized area, as designated by the 2000 Census. The mainstem of Brush Run flows for approximately 4.5 miles in a northwesterly direction to its confluence with Chartiers Creek just north of Thompsonville. Approximately 24.1 miles of streams drain the 10.0 square mile watershed. Protected stream uses in the watershed include aquatic life, water supply, and recreation. |
