Subject: Compliance Evaluation Inspection
NPDES Wastewater Treatment System
Bayleaf Fire Station No. 1
Certificate of Coverage No. NCG551416
Wake County
Dear Mr. Forestieri:
On June 20, 2018 Cory Larsen, PE from Wake County Department of Environmental Services,
on behalf of the Division of Water Resources, visited the subject wastewater treatment system to
evaluate compliance with the above permit to discharge wastewater. Cory Brantley was present
for the inspection and his assistance was appreciated. The following comments are highlighted
as a result of the inspection(also refer to the attached inspection report).
The treatment units were operating normally at the time of the inspection however, recent
effluent results indicated above-limit fecal coliform concentration in the effluent. The operator
explained that the sample was collected with the EZ Treat control panel run in "Test Mode"
which creates turbulence and is believed to have artificially agitated the biofilm contained in the
recirculation tank. This tank was pumped of solids during the last year as required. The
inspector believed the result may have been a false exceedance. The operator was instructed to
sample effluent in a different manner to reflect normal discharge conditions.
Please make efforts to collect effluent samples from the discharge pipe during normal discharge
conditions and report the next monitoring event results directly to Cory Larsen at
cory.larsen a,wakegov.com or 919-480-9998.
If you have any other questions you may also contact m 19-791-4200.

WCES inspected the system with Cory Brantley on June 20, 2018. The treatment units were operating
normally. Effluent results indicated above limit fecal concentration in effluent and the operator
explained that the sample was collected with the EZ Treat control panel run in"Test Mode"which
creates turbulence and artifically agitates the biofilm contanied in the recirculation tank. This result was
probably a false exceedance.The operator was instructed to sample effluent in a different manner to
