Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Jim Gonsiewski and Alex Lowe of the NC Division of Water Resources (DWR), Winston-Salem
Regional Office, met with Gary Simcox of S&ME at the Davie County Law Enforcement Center on
December 2, 2020, to perform a compliance evaluation inspection of the facility's groundwater
remediation system.
Two connected PVC pipes were observed at the bottom of the ravine which is the headwaters of
Leonard Creek, into which the effluent from the system is discharged. According to Mr. Simcox, these
pipes were formerly part of the discharge discharge system for the effluent. A heavy rain flooded the
ravine and broke the pipes off the system. Currently, a single 3-inch PVC pipe with a T-fitting serves
as the effluent pipe for the remediation system.
The following deficiencies were noted from the inspection:
There was one permit limit exceedance noted in the quarterly effluent results table from January 2016
through September 2020. Naphthalene (15 ug/L) slightly exceeded the permit limit of 12 ug/L in
February 2019). No other exceedances were noted in the analytical data for the period reviewed. Also,
the third Quarter 2019 sampling event was not conducted.

Comment: Accordina to Mr. Simcox. no maior chanaes have been made to the aroundwater
remediation system since the last inspection. The system consists of 12 recovery wells, of
which 6 are currently used, an oil/water separator, a free product storage tank, a shallow
tray air stripper, two bag filters, two activated carbon vessels, a flow totalizer, and an effluent
discharge pipe. The flow is measured using an in -line totalizer which is located after the
activated carbon vessesls. The average flow since January 2016 was approximately 1,940
gallons per day. The average flow when the system is running is approximately 2 gallons
per minute. The effluent samples are collected from a spigot which is situated after the
activated carbon vessels.
