Subject: NOTICE OF VIOLATION/NOTICE OF INTENT TO ENFORCE
NOV-2015-DV-0106 (Incident # 201500668)
Horsehead Corporation
Rutherford County
Dear Mr. Staley:
Donald R. van der Vaart
Secretary
On Saturday, April 25, 2015, depleted aqueous electrolyte solution was released due to failure of an elevated process
pipeline at the site. Reportedly, the majority of the release was contained onsite during recovery efforts; however, an
estimated 4000 gallons of this solution mixed with storm water reached a dirt road, approximately 100 feet to the north,
and an adjacent earthen drainage ditch. Solution reaching the earthen ditch was conveyed offsite to an unnamed, .
intermittent stream leading to the Broad River.'Based on an initial review of chemical information associated with the
depleted aqueous electrolyte solution, primary constituents of concern consist of metals, especially cadmium, lead, and
zinc. Additionally, the aqueous solution contained sulfuric acid with a pH range of 1 to 3 standard units.
Instream pH was monitored by the Division of Water Resources in both the unnamed tributary and the Broad river
upstream and downstream of,the spill. The unnamed tributary displayed low pH both upstream and downstream of the
spill. The Broad River pH was within normal ranges both upstream and down of the confluence with the unamed
tributary. Samples for the analyses of metals were not collected at the time of the spill response.
Violations
As a result of the above -referenced observations on April 25, 2015, the following violations are noted:
(1) illegal discharge
Violation I. Discharge Without a Valid Permit

-The Permittee shall comply with Final Effluent Limitations by the effective date of the Certificate of Coverage.
Pennittee shall at all times provide the operation and maintenance necessary to operate the existing facilities in accordance
with Standard Conditions for NPDES Permits Section C.2. of this permit.
Permittee shall operate the existing facilities such that constituents and/or characteristics of the discharge qualify for
Certificate of Coverage under the General Permit in accordance with 15A NCAC 02H .0127. In accordance with NPDES
regulations at § 122.45, allowing detection of a pollutant: Instances could arise where the combination of process and
non -process wastewaters result in dilution of a pollutant of concern such that it would not be detectable using approved
analytical methods. Internal monitoring would enable characterization of the pollutant before dilution with other
wastewaters.
The upstream location for the natural water temperature shall be interpreted as the influent to the penstock or other
appropriate location in the impounded waterbody. Effluent is the outflow from the powerhouse. The temperature
change between these two values is considered the heat added and judged for compliance with Note 1 of the permit
and 15A NCAC 2H.0211 6).
SECTION C. APPLICABILITY
This permit is applicable to the following types of discharges defined below:
1. Non -contact cooling water and open recirculation cooling water systems used in industrial processes for the sole
purpose of cooling machinery and other equipment. Non -contact cooling water is defined as water used for cooling
which does not come into direct contact with any raw material, intermediate product, waste product or finished
product. Contact cooling water is defined as cooling water that comes into contact with raw material, intermediate
product, finished product, byproduct or waste product. Open recirculating cooling water systems, continuously reuse
the cooling water which passes through the heat transfer equipment. Open recirculating cooling water system
discharges to a Water Supply'water body may require an individual NPDES permit. Contact cooling water discharges
require an individual NPDES permit.
2. Condensate wastewater from atmospheric cooling systems.

13. a) This connection is not possible due to a combination of the overall flow rate and the lack of BOD.
The Town of Forest City did not want to accept this discharge. It is their opinion that this flow
would render the package WWTP inoperable.
b) Subsurface disposal is not practical due to the low available acreage, steep slopes, proximity to
streams and low infiltration rates of the existing soil.
c) Spray irrigation is not practical due to the low available acreage, steep slopes and stream
proximity.

To Whom It May Concern:
Due to the volume and chemical makeup of the wastewater associated with the proposed boiler,
cooling tower and air compressor blow downs, the Town of Forest City strongly encouraged
Horsehead to seek an alternate source of discharge as opposed to releasing this in the Town's
sewer system.

BIOCIDE/CHEMICAL TREATMENT
WORKSHEET-FORM 101
The following calculations are to be performed on any biocidal products ultimately discharged to the surface waters of
North Carolina. This worksheet must be completed separately for each biocidal product in use. This worksheet is to be
returned with all appropriate data entered into the designated areas with calculations performed as indicated.

What is the Average Daily Discharge (A.D.D.) volume of the water handling systems to the receiving water body?
A.D.D. = 0.822 (in M.G.D.)
Please calculate the Instream Waste Concentration (IWC in percent) of this discharge using the data entered
above.
IWC = (A.D.D.) X 100 = (0.924 X 100
(7Q10)(0.646) + (A.D.D) (-xoi)(0.646) + (o.&A 0 •G���
This value (IWC) represents the waste concentration to the receiving stream during low flow conditions.
What is the name of the whole product chemical treatment proposed for use in the discharge identified in Part I?
Please list the active ingredients and percent composition:

What feed or dosage rate (D.R.) is used in this application? The units must be converted to maximum grams
of whole product used in a 24hr period.
D.R.= '70. 9� grams/24hr period
Please note, fluid ounces (a volume) must be converted to grams (a mass). The formula for this conversion is:
Grams of product = fluid oz. of product X 1 gal. water X 8.34.lbs. X specific gravity of product X 453.59g.
