Background Summary - This groundwater remediation system was first permitted in January 2005, flow -
limited at 0.0216 MGD. Recent flows however average much less at—0.0032 MGD (2018-2019). Records
suggest that volatile organic compounds (VOCs) as chlorinated hydrocarbons were lost to the environment
stemming from the Permittee's past use of a single 55-gallon drum of solvent (TCE) inadvertently leaked
upstream of Stewarts Creek, classified WS-III. Site -assessment soil and groundwater sampling detected
TCE and various chlorinated -hydrocarbon "daughter -products of decomposition" [see NPDES permit
effective 0lFeb2005].
Receiving -Stream - This facility discharges via a man-made conveyance [ditch] under zero -flow receiving -
stream conditions [summer 7Q10 flow = 0.0 cfs] to an unnamed tributary (UT) to Stewarts Creek in the
Yadkin -Pee Dee River Basin. Stewarts Creek is currently classified WS-III and is not listed as impaired [not
303d-listed in the Basin Plan].
Compliance - WET -tests records indicated all "Pass." After the initial treatment -system start-up, VOCs
were not detected in the effluent above test -method practical quantitation levels (PQLs) suggesting an
appropriately designed and well -operated treatment facility. DWR relaxed the monitoring frequencies from
2/Month to Monthly for the 2010 and 2015 permit renewals — no changes recommended.
Summary of Renewal Changes: Updated site map and text to include Rule citations; updated facility
description [Supplement to Cover Sheet]; updated text for eDMR submittal [see section A. (3.)].
