Watershed boundaries and Hydrologic Unit Codes (HUCs) were acquired from the Watershed Boundary Dataset (WBD), which delineates surface water drainage areas based on land area and topography. The HUC system provides a tiered approach to classifying and identifying these drainage areas.</SPAN></SPAN></P><P /><P STYLE="margin:0 0 0 0;"><SPAN><SPAN>For its four Ohio counties (Butler, Clermont, Hamilton and Warren) OKI obtained most of the watershed data and water quality assessments from the </SPAN></SPAN><SPAN STYLE="font-style:italic;"><SPAN>2010 Ohio Integrated Water Quality Monitoring and Assessment Report </SPAN></SPAN><SPAN><SPAN>(Ohio Environmental Protection Agency, Division of Surface Water, 2009-10). This includes evaluations of aquatic life uses, recreational uses, public water sources, and human health risks related to fish consumption. For each impaired watershed, the Watersheds Layer notes the status of a Total Maximum Daily Load (TMDL) study, which determines the total maximum daily loads of selected pollutants that can enter an impaired stream without ruining efforts to improve stream health. The layer also notes significant stewardship groups that have been organized to improve water quality in each watershed. OKI’s Stream Database Glossary defines the widely accepted concepts, specialized terms and acronyms associated with watersheds and water quality.</SPAN></SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /></P></DIV></DIV></DIV>

The Ohio data covers all publicly owned treatment works (POTWs) and many of the smaller wastewater treatment plants at mobile home parks, apartment and condominium complexes, schools, restaurants and a highway rest area. For the Kentucky portion of its planning area, OKI has data on wastewater treatment plants in Boone, Campbell and Kenton counties. For the Indiana portion of its planning area, OKI has data on wastewater treatment plants in Dearborn County. Overall, the data is more developed for the Ohio and Indiana portions of OKI’s planning area because the environmental agencies in those two states provided OKI with federal funding to update water quality management plans for Butler, Clermont, Hamilton and Warren counties in Ohio and Dearborn County in Indiana.</SPAN></P><P STYLE="text-align:Justify;margin:0 0 0 0;"><SPAN /></P><P STYLE="text-align:Justify;margin:0 0 0 0;"><SPAN><SPAN>In a departure from earlier geospatial data on wastewater treatment plants, the updated feature class provides point information on the location of a wastewater treatment plant itself rather than the location of the plant’s discharge outlet to nearby surface water.</SPAN></SPAN></P><P /><P STYLE="text-align:Justify;margin:0 0 0 0;"><SPAN><SPAN>Work on the updated wastewater treatment plant feature class began in September 2009 and continued through May 2011.</SPAN></SPAN></P><P><SPAN /></P></DIV></DIV></DIV>

Copyright Text: OKI staff created this geographic information system layer with wastewater treatment plant permit data compiled from the Ohio Environmental Protection Agency (OEPA), Indiana Department of Environmental Management and the Kentucky Division of Water. Plant locations were pinpointed through a reiterative process that relied on geographical coordinates from NPDES permits, aerial photographs, existing OKI data, county engineer maps, U.S. Geological Survey topographical maps, and the advice of local agencies when necessary. Average daily flows were obtained from OEPA in Ohio, wastewater treatment providers in Indiana, and NPDES permits in Kentucky.
