Pretreatment Annual Report (PAR) for the year of 2019 (due 20 ECEIVED
For the industries that discharge to MAR 03 2020
Gunpowder Creek WWTP- City of Lenoir NCDEQ/DWR/NPDES
A. General Program information: Enclosed is a copy of the Pretreatment Program Info
sheet provided by the PERCS unit. PPS, form, SNCR form, IDSF forms, and AT. As shown
Beocare is SIU permit # 008 and has 1 discharge pipe. Lenoir Mirror is SIU #007 with 1
discharge pipe. These two industries discharge to the collection system that flows to
the Gunpowder Creek WWTP. The analysis results of the permitted parameters do no
show over allocation as per the AT provided in the HWA; permit limits should remain
the same.
B. General permit information for Gunpowder Creek: No new industries were added as
permitted SIU's in 2019.
1. Beocare: is a medical textiles facility discharging domestic waste and process
wastewaters to the collection system. The WWTP monitored the flow, analyzed
for BOD, TSS, Cr, Cu, and Zn.
2. Lenoir Mirror: is a metal finishing facility discharging domestic waste, process
wastewaters and wash waters to the collection system. The WWTP monitored
the flow, and analyzed for BOD, TSS, As, Cd, Cr, Cu, CN, Pb, Ag, Zn, and Total
Metals. Total Toxic Organics (TTO) shall also be monitored, but a certification
statement may also be used for TTO's.
IU INFORMATION
A. IU's: SIU —permit 007 Lenoir Mirror
B. SIU —permit#008 Beocare
C. IU's in SNC information:
1. All the 2018 chromium issues at Beocare were addressed and corrected. A
recirculation system was added at the dye vats so the water could be reused.
2. There were no SNC violations for the year 2019
