Final Integrated Report Submitted to
EPA Region 2
The New Jersey Department of Environmental Protection (Department) has submitted the 2006 Integrated Report package, which includes the 2006 303(d) List, to USEPA. (USEPA issued guidance in July 2005 for preparation of the 2006 Integrated Report that encouraged states to integrate the 305(b) Report and the 303(d) List into one report.
The Department chose to make several changes to the assessment process for the 2006 Integrated Report. A subwatershed design was chosen to establish assessment units rather than the combination polygon/linear river stretch assessment units used in 2004. A modified USGS HUC-14 coverage was used to delineate the assessment units for all rivers, estuaries, and ocean waters except for the Delaware River and Bay, which reflect the Delaware River Basin Commission's river zone delineations. Lake assessment units were unchanged from the 2004 Integrated Report. Placement on the Integrated List was by designated use within each assessment unit rather than by pollutant/waterbody combinations. An impaired waters list was developed, which includes the assessment units identified on Sublist 5 of the Integrated List and the pollutants associated with the impairment of waters in their respective assessment units.
Results from the Integrated List have been digitized for use with the Department's on-line interactive mapping tool called "iMapNJ". This tool allows the viewer to explore the spatial relationships between waters of the State, their designated uses, use attainment status, spatial extent of impairment (if any), pollutants causing impairment (if known), and other geographical features available through iMapNJ such as roads and highways, political boundaries, open space, recreational areas, etc.
The Integrated Report was developed in four discrete phases:
Phase 1: Data Solicitation
The Integrated Report incorporates, as appropriate, information received in response to the Department's notice soliciting water quality related data. The Department provided notice in the New Jersey Register (37 N.J.R. 361 (a)) and on the Department's Web site on January 18, 2005. Data collected, as of December 31, 2004 was accepted for a 6-month period ending June 16th. Any data received after that date will be used for subsequent assessments as outlined in the January 2005 notice.
Phase 2: Integrated Water Quality Monitoring and Assessment Methods Document
The assessment methods used to develop the 2006 Integrated Report have been significantly enhanced. The 2006 Integrated List is based on subwatersheds rather than the river miles associated with a specific monitoring location. By creating a master list of waterbodies or subwatersheds, the Department will be able to prioritize monitoring needs in subwatersheds that are unassessed and better track water quality improvement over time.
The Department updated the Methods Document and provided a draft of the Methods Document to the public for comment. The notice was placed in the New Jersey Register on September 19, 2005 (37 N.J.R. 3733(b)) and a thirty-day comment period was provided. After review and consideration of comments received on the proposed Methods Document, the Department finalized the Methods Document.
The methods used to develop the Delaware River assessments were developed by DRBC, which is located at 25 State Police Drive, P.O. Box 7360, West Trenton, New Jersey 08628-0360 Phone: (609) 883-9500. For more information, contact Jonathan Zangwill at firstname.lastname@example.org.
Phase 3: Preparation of the Integrated List
The proposed Integrated List of Waterbodies was announced by public notice (38 N.J.R. 1878(a)) and made available for review and comment. A public information session outlining the changes in the methodology used to develop the Integrated List was held on May 4, 2006, during the initial 30-day comment period. The Department received requests for an additional information session, which was held on June 1, 2006. The Department extended the comment period an additional 2 weeks, from May 31 to June 14, 2006, to allow for submission of comments following the second information session.
Once the Integrated List (Appendix A-1 and A-2) was completed, the 303(d) List of Impaired Waterbodies with priority ranking (Appendix B), the List of Delisted Waters (Appendix C), and the 2-year TMDL schedule (Appendix D) were developed.
Phase 4: The Integrated Report
The Department prepared the Integrated Report, including assessment results represented in a spatial context, detailed descriptions of data sources, monitoring needs and schedules, and TMDL schedules. The Department also prepared a summary description of the various water quality-related programs that serve or could serve as management strategies to maintain, enhance, and restore water quality in the State's waters.
