EPA Efforts To Specify Bay Water Pollution Loads May Set National Model

摘要

EPA plans to test its ability to identify the nutrient pollution contributions from all point sources - including municipal stormwater dischargers and concentrated animal feeding operations (CAFOs) - in its watershed-wide Chesapeake Bay cleanup plan, with the goal of replicating the effort nationally, according to EPA Bay chief Chuck Fox.rnWhen EPA develops a waterbody cleanup plan, known as total maximum daily load (TMDL), it takes into account both point sources and nonpoint sources of pollution and allocates a portion of the total pollution limit to each type of source. But historically the agency has not further distinguished between different types of point sources, Fox said April 13 at a meeting on watershed issues hosted by the Horinko Group, an environmental consulting firm.
