Subject: Request for Additional Information
NPDES Renewal Application
Wieland Copper Products, LLC .
NPDES permit NCO035173
Stokes County
The Division has reviewed your application; received on August 9, 2016, for renewal of NPDES permit
NC0035173. To enable us complete our review in accordance with N.C.G.S. 143-215.1 and 15A NCAC
2H.0.105, please provide additional or revised information to address the following comments:
1. Please provide five (5) days of Total Hardness (CaCO3 or (Ca + Mg)) data for the effluent at
Outfalls 001, 002, and 003.
2. If possible, please provide five (5) days of Total Hardness (CaCO3 or (Ca + Mg)) data from
locations upstream from 001, 002 and 003. Upstream sample locations should the same as locations
used for permit Temperature and Dissolved Oxygen sampling for each Outfall.
The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Committee (EMC) on November 13, 2014. The US EPA subsequently
approved the WQS revisions on April 6, 2016 with some exceptions. The NC Division of Water
Resources is required to implement the new dissolved metal standards in all permits public noticed after
April 6, 2016.
The new standards for most metals include acute standards. Furthermore, the freshwater standards for
several metals are expressed as the dissolved form of the metals, and seven metals have hardness -
dependent equations. As a result, the Division will need site-specific effluent hardness data and instream
hardness data, upstream of the discharge, for each facility monitoring these metals in order to calculate
permit limitations. For Wieland Copper Products, LLC, the dissolved metals standard of concern is for
dissolved Copper.
To evaluate dissolved Copper, a Reasonable Potential Analysis (RPA) was conducted using data for 4 %2
years Qu12012—Dec2016) [see attached RPA spreadsheets for Outfalls 001, 002 and 003]. Results

indicated a reasonable potential to exceed the new dissolved metals standard for Copper. Consequently,
the following daily maximum limits (acute total allowable metal concentration) and monthly average
limits (chronic total allowable metal concentration) for Total Copper may be added to the individual
permit for renewal:
Outfall Monthly Average Limit Daily Maximum Limit
001 23.13 µg2 26.69 gg/L
002 7.88 gg/L 10.47 gg/L
003 7.88 µg/L 10.47 gg/L
Please note a default effluent and upstream hardness of 25 mg/L was used for the calculation of the limits
above. Please see the attached Dissolved to Total Metal Calculator for a summary of information used for
these limit calculations. This information includes effluent flow information and stream flow information
such as the 7Q10.
If no response is received within 60 calendar days [per 15A NCAC 2H.0107(b)], the permit will be
renewed without the benefit ofthe requested additional information. Therefore, a default effluent and
upstream hardness of 25 mg/L (CaCO3 or (Ca + Mg)) will be used to calculate an effluent limit for Total
Copper giving the above daily maximum limits and a monthly average limits.
If you have any questions, please contact Derek Denard at 919-807-6307 or email at
derek.denardAncdenr.gov.

Derek Denard, Environmental Specialist
