TMDL Project Location and Background The Knox Creek watershed is primarily located in Buchan- an County, Virginia with a small poron in Pike County, Kentucky. The 56,123 acre watershed is in the Tennessee/ Big Sandy River basin. The watershed is primarily forest- ed, with a small amount of agricultural land (604 acres) and some acve mining, abandoned mining and reclaimed mining land (3,710 acres). Pawpaw Creek is a tributary to Knox Creek. DEQ developed TMDLs for Knox and Pawpaw Creeks in 2006 including a bacteria TMDL for Pawpaw Creek, total dissolved solids (TDS) TMDLs for both creeks, and a sediment TMDL for Pawpaw Creek. DEQ developed a TMDL implementaon plan in 2008. The Knox and Paw- paw Creek TMDL implementaon project was supported by Secon 319 (h) funds, and was administered by the Big Sandy Soil and Water Conservaon District. The project started in July 2012 and ended December 2014.

Project Location and BackgroundThe Knox Creek watershed is primarily located in Buchan-an County, Virginia with a small portion in Pike County, Kentucky. The 56,123 acre watershed is in the Tennessee/Big Sandy River basin. The watershed is primarily forest-ed, with a small amount of agricultural land (604 acres) and some active mining, abandoned mining and reclaimed mining land (3,710 acres). Pawpaw Creek is a tributary to Knox Creek. DEQ developed TMDLs for Knox and Pawpaw Creeks in 2006 including a bacteria TMDL for Pawpaw Creek, total dissolved solids (TDS) TMDLs for both creeks, and a sediment TMDL for Pawpaw Creek.

Closeout AnalysisThe Knox and Pawpaw Creek project period was 2 and a half years. DEQ decided to discontinue targeted 319 funding to the project as of December 2014 due to several reasons which included:

No progress was made in the agricultural BMP program in the watershed. Much of this could be attribut-ed to the limited amount of farmland in the watershed. No fencing practices were installed or waste storage systems for equine. The IP identified that 14 livestock exclusion systems and 15 waste storage systems (equine) were needed.

Lack of pre-project planning to gauge interest in adoption of agricultural BMPs referenced in IP.

Implementation of residential septic practices was not successful with only 7 of 580 (1%) of the repairs and replacements of failing septic systems and straight pipes removed based on the IP were actually completed during the project period. Even septic tank pumpout a relatively inexpensive BMP (grant funds were available to pay 50% of the cost) was not an effective practice in the Knox and Pawpaw Creek watershed.

Due to local geology and topography in Buchanan County alternative discharging sewage systems are more commonly used as opposed to conventional sewage systems. Section 319 funds cannot be used to cost-share on sewage systems that require a VPDES permit. BSSWCD was not aware of this going into the grant funded project.

Project was located in an area where even with 50% to 75% cost-share to repair and replace sewage systems property owners need additional assistance to correct the problems. In such cases, DEQ needs to work with the project sponsors to leverage additional funding from other sources to provide more financial assistance in order to be successful.

Water Quality ImprovementsThe 2014 Integrated report (that analyzed data from 2007-2012) listed the following as still impaired:

Paw-Paw Creek Benthic: VSCI Score of 50, 36 and 47 in 2004 and 2006 Pathogens: exceedances of 33%, 50%, and 41%

Knox Creek Benthics: VSCI scores not listed in report, but all were indicating impairment

Due to limited amount of BMP implementation that was accomplished during the project period, additional water quali-ty data was not analyzed.
