A wastewater treatment plant is a facility containing a series of tanks, screens, filters and other processes by which pollutants are removed from water. <\/SPAN><\/SPAN>The wastewater treatment plant feature class was compiled from information found in National Pollutant Discharge Elimination System (NPDES) permits.<\/SPAN><\/P>

<\/P>

For the Ohio portion of its planning area, OKI has geographic and operational data on wastewater treatment plants in Butler, Clermont, Hamilton and Warren counties. 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\u2019s 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>

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\u2019s discharge outlet to nearby surface water.<\/SPAN><\/SPAN><\/P>

Work on the updated wastewater treatment plant feature class began in September 2009 and continued through May 2011.<\/SPAN><\/SPAN><\/P>
