Storm Water

Water Cycle, rain to rivers and ground water

In the Clean Water Act (1977), the EPA designated state agencies to develop water quality standards, perform water quality monitoring to understand  current conditions, determine sources of pollution , and develop Total Maximum Daily Loads (TMDL) as a tool to improve water quality.

DEQ has identified federal, state, and local agencies as Designated Management Agencies (DMA), as those agencies have authority to manage and regulate sources of pollutants listed in the TMDL.  The City of Harrisburg has been identified as a DMA.  The TMDL is an order that requires the City to develop its own implementation plan outlining actions the City will take to meet the requirements of the TMDL.
