Modeling
and TMDL Unit :: The N.C. Water Quality Assessment and Impaired Waters List (305(b) and 303(d) Report)
What is the 303(d) list?
Section 303(d) of the Clean Water Act (CWA) requires states to develop a list of waters not meeting water quality standards or which have impaired uses. Listed waters must be prioritized, and a management strategy or total maximum daily load (TMDL) must subsequently be developed for all listed waters.

What is the Integrated Report?
In 2002, North Carolina prepared the first North Carolina Water Quality Assessment and Impaired Waters List, also referred as the 2002 Integrated Report. This report is based on US EPA guidance issued during the latter portion of 2001 and fulfills requirements of previous 305(b) reports and 303(d) lists of impaired waters. A provisional final report was approved on March 18th, 2003.
The 2002 Integrated Report is made available in two pieces: the report itself which contains the impaired waters list, and a database of all waters currently supporting uses or for which there was insufficient information to rate.

Submitting Data
The North Carolina Department of Environment and Natural Resources, Division of Water Quality (NCDENR-DWQ) invites all interested parties to submit water quality data and information.
Submitted information will be considered in assessing the health of the waters in the basin. This information is relevant to the development of the Basinwide Water Quality Plans and as a reporting requirement to the US EPA under Section 303(d) of the Federal Clean Water Act. NCDENR-DWQ staff will evaluate submissions to determine if they are applicable and useful to the basinwide planning process or 303(d) reporting requirements.
Submission Criteria:
- Letters, including photographs and other information, may be submitted regarding the uses of surface waters for boating, drinking water, swimming, aesthetics, and fishing.
- Summary reports and memos including distribution statistics will be accepted. If information includes summaries of chemical or biological sampling data, maps showing sampling locations must be included. All information must be scientifically valid and verifiable by NCDENR-DWQ staff.
- Raw data should be submitted electronically and must be accompanied by the methods used to collect and analyze the samples. Documentation of applicable quality assurance/quality control programs in a Quality Assurance Project Plan (QAPP) is required.
- Qualifiers must be in separate fields and must be defined (e.g. < is non-detected value).
- Pollutant name, with units, must be defined. STORET codes may also be used.
- All sampling locations must be referenced on maps and with latitude and longitude. Electronic maps will be accepted in Adobe Acrobat, ArcView shapefile, tif, gif, jpg, and bmp image format. For co-located samples at multiple depths, depths must be specified in a separate field in the database.
- Electronic data will be accepted in delimited ASCII, spreadsheet (e.g., Excel, Quattro Pro, Lotus 1-2-3), or database (e.g., Access, dBase, or SAS) platforms.
The name and telephone number of a contact person must also be provided with information submitted. NCDENR-DWQ will call this person if questions arise concerning the information. The information submitted will not be returned.
Information not received as specified in this solicitation may not be considered.

Quality Assurance Project Plan
The purpose of a Quality Assurance Project Plan (QAPP) is to document planning results for environmental data operations and to provide a project-specific blueprint for obtaining the type and quality of environmental data needed for a specific decision or use. Stakeholders (i.e., data users, data producers, decision makers, etc.) should be involved in the planning process to make sure as many possible needs can be addressed with the project.
DWQ reserves the right to make all final interpretations of data submitted and whether that data represents a contravention of use-support.
Guidance for developing the QAPP:
EPA general guidance
EPA volunteer monitoring guidance
