QUALIFIERS
Project: Quarterly Storm Water
Pace Project No.: 92399575
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
Pace Analytical Services, LLC
9800 Kincey Ave. Suite 100
Huntersville, NC 28078
[phone]
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.

Based on our discussions during the meeting held at the Mooresboro facility on April 11, 2017
between Horsehead Metal Products, LLC ("HMP") and representatives of the North Carolina
Department of Environmental Quality ("DEQ"), including yourself, HMP is requesting a
modification to the stormwater permit for the HMP facility (referenced above) located at 484
Hicks Grove Road, Mooresboro, NC 28114. Described below are the agreed -upon minor
changes being requested:
1) Section B: Analytical Monitoring Requirements:
a. The monitoring schedule contained in Table 2 should be changed to reflect a new
start date for the facility. Given that the precise future date on which the facility
might commence operations is undetermined, HMP proposes inclusion of general
language that references "the date on which the plant begins zinc production,"
with monthly reporting to resume after that date. We hope to begin production of
zinc during 2018, but planning for that has yet to completed, therefore that
general time frame remains uncertain.
b. Remove the requirement to provide a Summary Report given the conclusion at the
April 11 meeting that this has been deemed to be complete.
2) Include language in the permit noting the stormwater samples taken at SDO 01 are
representative of the contribution of the existing stormwater flows from the general site,
including the ponds in the SX area.

Development of an engineering plan is underway to address the process issues that were
experienced during the original start up phase. HMP will continue to adhere to the requirements
of the existing permit.
Please send a draft of the modified permit to me for review at your earliest convenience. If you
have questions or comments, please contact me or Jim Harris.

Abnormal Operating Events:
10-24-16 the flange gasket on a four inch process water line failed and discharged approximately 800 gallons of water to the roadway between
the cellhouse and the electrolyte storage tanks. The water flowed into a storm drain and down to the energy dissipater at Basin I. The water was
collected in Basin I and no discharge occurred to the Broad River.
