Dear Mr. Mayberry:
Lenoir Mirror Company (LMC) personnel performed a stormwater monitoring event for their facility at 401
Kincaid Street in Lenoir, Caldwell County, North Carolina. The stormwater sampling event included the
collection of a stormwater sample and outfall observations for qualitative parameters during a
representative and measurable storm event The monitoring was conducted in general conformance with
the requirements of the State of North Carolina Department of Environmental Q�al�ty.r'(NCDEQ), National
Pollutant Discharge Elimination System (NPDES), LMC stormwater permit(SWP)`NS0.6
On April 12, 2016, a stormwater sample was collected at the designated discharge point, Stormwater
Discharge Outfall (SDO#1), based on a storm event that meets the requirements for monitoring The
collected sample was submitted to North Carolina-accredited Blue Ridge Labs in Lenoir, North Carolina,
for analysis of total suspended solids (TSS) by EPA Method SM2540D-11, biochemical oxygen demand
(BOD) by EPA Method 405.1, chemical oxygen demand (COD) by Standard Method 5220D, total silver
and lead by EPA Method 200.7. A total rainfall amount reading was collected from a nearby gauging
location Results of visual observations, qualitative parameters, and the total rainfall reading are provided
in the attached SDO Qualitative Monitoring Report and SDO Monitoring Report.
Laboratory results and observations of qualitative parameters indicated that the specified monitoring
parameters were within discharge benchmark values as outlined in the NPDES SWP NCS000061 Field
pH was not measured during the monitoring. LMC will assure that pH data are collected during future
monitoring events.
Please note that the SDO Qualitative Monitoring Report and SDO Monitoring Report requires certification
by the signature of permittee (Lenoir Mirror employee) before submittal of the entire report to the address
on page one of the SDO Monitoring Report. If you have any questions, please contact us at 704-529-
