New Jersey Integrated Water Quality Assessment Report
(includes 305(b) Report and 303(d) List)

The federal Clean Water Act mandates that states submit biennial reports to the U.S. Environmental Protection Agency (USEPA) describing the quality of their waters. The biennial Statewide Water Quality Inventory Report or "305(b) Report" must include the status of principal waters in terms of overall water quality and support of designated uses, as well as strategies to maintain and improve water quality. The 305(b) reports are used by Congress and USEPA to establish program priorities and funding for federal and state water resource management programs. The biennial List of Water Quality Limited Waters or "303(d) List" identifies waters that are not attaining designated uses because they do not meet surface water quality standards despite the implementation of technology-based effluent limits. States must prioritize waters on the 303(d) List of Water Quality Limited Waters for Total Maximum Daily Load (TMDL) development and identify those high priority waters for which they anticipate establishing TMDLs in the next two years. The Integrated Water Quality Assessment Report (Integrated Report) combines and satisfies the reporting and public participation requirements of Sections 305(b) and 303(d) of the federal Clean Water Act (along with Section 314 Clean Lakes Program). All current and historic water quality assessment documents, as well as relevant USEPA guidance, are available on this Web site's Technical Support Documents web page.

Integrated Reports are intended to provide effective tools for maintaining high quality waters and improving the quality of waters that do not attain their designated uses (i.e., contain impaired waterbodies). New Jersey's Integrated Reports describe attainment of the designated uses of surface waters of the State, as specified in the New Jersey Surface Water Quality Standards (N.J.A.C. 7:9B), which include: aquatic life, recreation, drinking water, fish consumption, shellfish consumption, industrial and agricultural. In addition to identifying impaired waterbodies, the Integrated Reports identify subwatersheds where there is no water quality impairment, i.e., all designated uses are attained.

Detailed information about the biennial water quality assessment process, the Integrated Report, and the related lists and documents is available from the links below. Information about previous Integrated Reports is also available at Technical Support Documents.
