Dear Mr. Sprinkle:
The Division of Water Resources(DWR or the Division)received your application for the subject permit(dated
11Jun2021). Please find attached a permit draft for you review.Please review this draft to ensure your
understanding of its limits and monitoring conditions,and to correct errors,if any.
Concurrent with this notification,the Division will solicit public comment on this draft by publishing a notice in
newspapers having circulation in the general Stokes County area,as required by the NPDES Program.Please
submit your written comments(if any),to my attention,NCDEQ/DWR/NPDES no later than June
September 30,2021 (approximately 30 days after receiving this document). We welcome your written
comments,but they are not mandatory.
The Division understands that Wieland Copper Products,LLC(Wieland)intends to transfer all effluents to
active Outfall 003 and discontinue discharge at Outfall 001 [001 to remain on standby].We understand your
intentions and requests include:
• Reroute effluent from the biological plant to the 100K storage tanks to be
treated in the process water treatment plant
• Reroute discharge from process water treatment plant to newly
installed copper removal resin system
• Install discharge to Outfall#003 from copper removal resin system
• Reclassify Outfall#001 to standby[inactive]but maintain in the permit.
Therefore,we offer the following:
Summary of Changes to the Previous Permit for Outfall 003:
• BOD5=5.0 mg/L(MA); 7.5 mg/L(DM) [DM=MA x 1.5]
• TSS=30.0 mg/L(MA);45.0 mg/L(DM)[DM=MA x 1.5]
• Fecal Coliform=200/100m1(MA);400/100 ml(DM) [DM=MA x 1.5]

• Upstream Monitoring is discontinued for Hardness/Temperature/Dissolved
Oxygen—not feasible under zero-flow receiving stream conditions
• Effluent Hardness continues,but Downstream Total Hardness monitoring
replaces Upstream(location to be determined).
The NPDES standard conditions(Parts II,III,and IV)that are a part of the permit are not included in this draft
document(cover,map,and Part I).The conditions are the same as in your current permit except that agency and
division names have been updated.The latest version is available at https://bit.ly/3k5NFaL and can be viewed
online or downloaded as a PDF file.
Following the mandatory 45-day Public Comment period,the Division will review all pertinent comments,if
any,and take appropriate action prior to issuing an NPDES permit final.
