The Delaware River Basin Commission (“DRBC” or “Commission”) is an interstate and federal compact agency that was created in 1961 by concurrent legislation of the States of Delaware, New Jersey, and New York, the Commonwealth of Pennsylvania and the United States Government for purpose of jointly managing the water resources of the Delaware River Basin.

DRBC currently is compiling data for the 2008 Delaware River and Bay Integrated List Water Quality Assessment (“2008 Assessment”) required by the federal Clean Water Act (CWA). The 2008 Assessment will report the extent to which waters of the Delaware River and Bay are attaining designated uses in accordance with Section 305(b) of the CWA and will identify impaired waters, which consist of waters that do not meet surface water quality standards.

The assessment methodology to be used to develop the 2008 Assessment will closely track the methodology used for the most recent assessment, completed in 2006. The 2006 assessment is available for review at​drbc/​06IntegratedList/​index.htm.

In the 2008 Assessment DRBC proposes to reduce the number of assessment units from the number used in 2006 by consolidating the units into DRBC's Water Quality Management Zones 1A, 1B, 1C, 1D, 1E, 2, 3, 4, and 5, the boundaries of which are defined in DRBC's Water Quality Regulations (18 CFR Part 410), available on the Web at​drbc/​regs/​WQRegs_​092607.pdf. The 2008 Assessment will continue, however, to include subunits within Zone 6 that are defined in part by shellfish management directives issued by the states of Delaware and New Jersey.
