EPA established revisions to existing Total Maximum Daily Loads (TMDLs) for the Christina River watershed, which includes Brandywine Creek, Red Clay Creek, and White Clay Creek in Delaware and Pennsylvania.These proposed revisions are being made to the Christina River Basin low-flow nutrient/dissolved oxygen TMDL in light of factors such as the availability of recent data and review of the computer model used to develop the original TMDLs.
