Carroll Engineering Corporation’s Allen Mason, P.E., Senior Vice President and Jim Horwath, an Engineering Technician attended a meeting hosted by West Whiteland Township of the Christina Watersheds Municipal Partnership (CWMP) on Wednesday April 12, 2017. The CWMP is a collaborative of 38 municipalities in the Brandywine, Red Clay and White Clay Watersheds.
The purpose of this meeting was to review the progress and key outcomes of the discussions between CWMP’s designated representatives and the PA Department of Environmental Protection relative to the procedures and methodologies for calculating sediment, phosphorus and nitrogen loads for stormwater management. The setting of the loading rates and reductions are key to selecting Best Management Practices and locations to meet the reductions stipulated in the Total Maximum Daily Load (TMDL). A TMDL establishes the maximum amount of a pollutant allowed in a waterbody and serves as the starting point or planning tool for restoring water quality.
