Impaired Waters 303(d) and 305(b) Reports

Virginia 2012 303(d) List Partial Approval

EPA Region 3 partially approved VADEQ’s 2012 303(d) list on December 12, 2013. EPA deferred final action on the assessment status of algal growth impacts on recreation uses in the Shenandoah River, North Fork Shenandoah River, and South Fork Shenandoah River (collectively, Shenandoah River). Final action on the assessment status of the Shenandoah River has been deferred due to algal growth information provided by the Shenandoah Riverkeeper to EPA and VADEQ. EPA and VADEQ have agreed to work cooperatively on the development of a methodology to evaluate algal growth in Virginia non-tidal rivers/streams that will be piloted on the Shenandoah River. EPA has provided support for the pilot study which will be led by the Interstate Commission on the Potomac River Basin. The Shenandoah study will make use of citizen monitors to collect information in a manner that could serve as a model for future use of citizen data regarding algal biomass.

Pennsylvania 2012 303(d) Listing Decision


On May 9, 2013, the U.S. EPA Mid-Atlantic Region approved Pennsylvania’s 2012 final 303(d) list of impaired waters.

The final list Exit EPA Click for Disclaimer includes a change in designation for a nearly 100-mile stretch of the main stem of the Susquehanna River from unimpaired for aquatic life use and recreational use to having insufficient information upon which to make an impairment decision. The change from the draft to the final list was based on concerns raised during the public review of the draft 2012 303(d) list regarding the health of the smallmouth bass population.  

The Pennsylvania Department of Environmental Protection is continuing studies begun last year into issues affecting smallmouth bass in the Susquehanna. We support the department’s additional data collection efforts and agree that, at this time, there is insufficient water quality data to support an impairment listing. We look forward to the results of these intense monitoring efforts and to other priority actions the department is taking to determine the causes of the problems facing smallmouth bass and to further assess water quality.

Additions to West Virginia’s 2012 Impaired Waters List


The United States Environmental Protection Agency (EPA) is adding 248 water bodies to West Virginia’s 2012 303(d) list. These segments are in addition to the 1,176 listed segments that EPA approved on March 25, 2013. The 303(d) list is a list of waterbodies that do not meet water quality standards and that need Total Maximum Daily Loads (TMDLs).

On March 25, 2013, the EPA partially approved and partially disapproved West Virginia’s 2012 303(d) list submittal.  Specifically, EPA approved WV’s proposal to list 1,176 water quality limited segments as impaired.  However, EPA disapproved WV’s failure to review all readily available data and information and not list 255 water quality limited segments as not meeting water quality standards and needing a Total Maximum Daily Load (TMDL). 

The EPA published a notice in the Federal Register and provided the  public an opportunity to review its proposed decision to add these water quality limited segments to West Virginia’ 2012 303(d) list between April 8, 2013  and May 8, 2013.  After considering comments received from the public, the EPA is adding 248 water bodies to West Virginia’s 2012 303(d) list. With EPA's final action, the 248 new listings will become part of West Virginia’s 303(d) list. 

Supporting documents related to the EPA’s final action can be viewed below.  The documents include: transmittal memo from EPA to WV, final list of waters to be added, response to comments document and copies of comments received by EPA.
