Curtis -Wright Controls, Incorporated
General Permit NCG030000,

Cleveland County
On August 4, 2014, our office received your report concerning the exceedances of the benchmark
values for zinc and copper. As discussed on April 8, 2014, due to repeated exceedances of zinc and
copper, it was recommended that you have your facility evaluated for sources of copper and zinc.
Please keep in mind that benchmark exceedances are NOT limit violations of permit conditions;
however, you are obligated to follow the tiered response actions outlined in your permit. Since the
renewal of the permit in November 1, 2012, the benchmarks for the parameters of zinc and copper
were exceeded during the standard semiannual monitoring events. The facility was found to be in
compliance with the tiered response actions and other conditions of the NCG030000 General
Permit. Cardno Incorporated was. retained to further evaluate the facility for causes of increased
levels of zinc and copper. Cardno Incorporated identified the air conditioning units and outside
storage of metal parts which may be contributing to the exceedances of benchmark values. After
reviewing the sampling report, it appears that the condensate from the air conditioning units was the
major contributor to the elevated levels of zinc and copper.
Based on the aforementioned items, we are granting regulatory relief in the form of a collapsed Tier
2 — Tier 3 response. Upon receipt of this letter, Curtis -Wright Controls, Inc. may resume the permit
specified semi-annual analytical monitoring for the remainder of the current permit term. This
decision applies only to the copper and zinc benchmarks. A benchmark exceedance of any other
parameter listed in your permit will trigger the tiered response actions as described in the general
permit.
You must notify this office, in writing, within five business days if you become aware of any
significant source of copper or zinc at your facility that has the potential to be exposed to
stormwater. The relief granted in this letter in contingent upon the current industrial practices at

Curtiss-Wright's facility located in Shelby, NC is authorized to discharge stormwater as set forth
in Permit NCG030000, COC NCG030258. As we discussed on April 8, 2014 Curtiss-Wright has
had repeated monitorings above benchmark for copper and zinc. Curtiss-Wright hired Cardno
ATC to evaluate our facility for sources of copper and zinc, attached is their report. Non-
industrial discharge from HVAC units is shown to be a source of copper and zinc. As indicated
by the report condensate from HVAC equipment at the Curtiss-Wright facility does not affect
water quality in the nearby tributary of Brushy Creek during normal flow conditions. Curtiss-
Wright would like to request a variance to discharge the typical copper and zinc concentrations
that have prevailed during previous monitoring events at our facility. Curtiss-Wright is currently
performing stormwater monitoring monthly, we would request that monitoring frequency be
decreased to semi-annual.
Thank you for your attention to this request. Should you have any questions or require
additional information, please contact Mr. Phillip Felkel of Curtiss-Wright at 704.481.2211 or by
email at [e-mail].

Cardno is pleased to provide Curtiss-Wright Controls, Inc. (Curtiss-Wright) with a condensate and
surface water evaluation report at the referenced facility. Curtiss-Wright operates a facility that produces
control and avionics equipment for the aerospace industry. Figure t shows the site location on part of a
United States Geological Survey Topographic Quadrangle Map, and Figure 2 indicates the site and
vicinity on an aerial photograph.
1.0 Background
The facility has an active Stormwater General Permit, NCG 30000, through the National Pollution
Elimination Discharge System (NPDES) regulations, and the permit allows discharge of stormwater from
the facility to the surface waters of North Carolina. The permit was renewed, effective November 1, 2012,
and in addition to the prior parameters, copper and zinc were added to the analytical requirements. Data
were collected for the new monitoring parameters during standard semiannual stormwater monitoring in
April and December 2013. Based on exceedence of benchmark values for copper and zinc during the
standard semiannual monitoring events, Curtiss-Wright conducted Tier II Stormwater Monitoring in each
month during the period of January through April 2014.
In summary, most monitoring parameters — including each of the prior monitoring parameters of
discharge characteristics, lead, pH, oil and grease, total suspended solids, and total toxic organics —
were within benchmark values before and after the permit changes. However, the copper and zinc
concentrations exceeded the benchmark values, with copper exceeding the benchmark values in each
outfall in each event and zinc exceeding the benchmark values in Outfall 3 during each event. Zinc also
exceeded the benchmark values on several occasions in the Outfall 4 location. The Outfall 3 and Outfall
4 drainage areas include a roof with air conditioning units which may be contributing copper and zinc
from cooling coils, and the Outfall 4 location includes outside storage of metal parts, which may also be
affecting the metals concentrations.

Shaping the Blare
Based on facility observations and discussions with Curtiss-Wright in late 2013 and based on review of
analytical summaries of stormwater data, particularly for copper and zinc, the intent of this evaluation has
been to test water discharge from specific air conditioning condensate drains on the roof of the facility
and to monitor local background surface water concentrations for copper and zinc during normal flow
conditions.
2.0 Condensate and Surface Water Sampling
Prior to commencing the sampling activities, Cardno prepared a site -specific Health and Safety Plan
(HASP) for use by ATC staff and subcontractors in accordance with the Occupational Safety and Health
Administration requirements (29 Code of Federal Regulations 1910.120). The HASP addresses the
potential physical and chemical exposure risks associated with the field environmental sampling
activities.
Sampling activities were divided into two parts: roof top heating, ventilation, and air conditioning (HVAC)
discharge sampling and surface water sampling. At the time of the stormwater evaluation, no
precipitation events had occurred within the past 24-hours, and the evaluation occurred during a day
when the outside temperature of between 79 and 88 degrees Fahrenheit and the relative humidity was
elevated.
2.1 HVAC Discharge Sampling
On June 16, 2014, Cardno mobilized to the facility to evaluate runoff associated with the HVAC systems
located on the roof. As part of the evaluation, the location and designation of each major HVAC
condenser was noted as well as the direction that condensate from the HVAC systems was flowing.
Water flow rates were estimated to be between 100 to 500 milliliters per minute from the larger active
HVAC units.
To evaluate the HVAC runoff Cardno collected water samples from the condensation discharge lines of
the larger HVAC systems that were in operation at the time of the evaluation, with the exception of AC-1
which was not in service at the time of sampling. However, the AC-1 unit had condensate water within a
vapor trap that was sampled. Smaller HVAC units were producing insufficient volumes for sampling.
Cardno placed the samples in laboratory -provided, certified -clean, and properly preserved containers;
entered the samples into chain -of -custody control upon collection; stored the samples in a cooler
containing ice for preservation; and submitted the samples for analysis to North Carolina -accredited
Prism Laboratories, Inc. in Charlotte, North Carolina. Prism analyzed the water samples for metals
(copper & zinc) by EPA Method 6010C.
The evaluation of flow showed that the HVAC units on the west side of the facility flow mostly to Outfall 3
and Outfall 4, with the majority of the flow to Outflow 3. On the east side of the facility the HVAC systems
flow to the east and south and likely discharge to Outfall 4. Figure 3 illustrates the direction water flow
from each HVAC unit. Table 1 summarizes the flow and outfall data.

2.2 Stream Sampling
Cardno'
Shaping the Forme
On June 16, 2014, Cardno collected three surface water samples from an unnamed tributary of Brushy
Creek. The samples were collected -from -locations that would be considered upstream to hydraulically
adjacent to the facility. Cardno-was-no#-able t�a-.collea-- s ri eam sample, because the nearest
publically accessible location was distant from the site in the First Broad River and closer locations were
on private, posted property. Cardno managed the surface water samples in a similar manner as
described for the condensate samples. Prism Laboratories also analyzed the water samples for metals
(copper & zinc) by EPA Method 6010C. Figure 4 provides the locations of the three surface water
samples.
2.3 Analytical Results
Analytical results show that copper and zinc were detected in each of the HVAC samples. HVAC Unit 1,
which was not operating, had stagnant water within the condensate line, and the sample from the
stagnant line had the highest concentrations recorded at the site: zinc at 46 mg/L and copper at 12 mg/L.
Other condensate had detections of copper that ranged from 1.3 mg1L at HVAC Unit AC-17 to 0.011
mg/L at AC-35. Concentrations of zinc in condensate ranged from 1.9 mg/L at HVAC Unit AC-15 to 0.039
mg/L at HVAC Unit AC-27. For reference, the benchmark values from the Stormwater General Permit
are 0.007 mg/L for copper and 0.067 mg/L for zinc.
Copper was not detected in the surface water samples, and the analytical detection limit was 0.0010
mg/L. The surface water standard for copper is 0.007 mg/L. Zinc was detected below the NC 2B Surface
Water Standard of 0.067 mg/L, at estimated concentrations ranging from 0.0082 to 0.0087 mg/L.
Concentrations of copper were detected above the stormwater permit limits and the NC 2B Standard in
each of the samples collected from each of the large HVAC systems that were sampled. Concentrations
of zinc were detected above the NC 2B Surface Water Standard in 16 of the 20 condensate samples and
above the permit benchmark values in 13 of the 20 condensate samples. Table 2 contains summary of
the HAVC analytical data, and Table 3 provides a summary of the surface water analytical data.
Appendix A contains the laboratory report and chain -of -custody document.
3.0 CONCLUSIONS AND RECOMENDATIONS
Cardno has completed the condensate and surface water evaluation at the Curtiss-Wright Controls
Facility in Shelby, North Carolina. Sampling and analysis performed during the evaluation indicated that
discharge of condensate from the-1 AC systems=is iikely the_princip`al sour-ce;f stormwater copper and
zinc concentrations that exceed stormwater permit limits_ The HVAC systems appear to generate a total
flow of several gallons per minute of condensate during normal operation. The majority of the water
generated during operations at the site from the roof is directed to either Outfall 3 or Outfall 4, with a
minor amount directed toward Outfall 1 and Outfall 2. Deposition of readily soluble copper and zinc on
roof surfaces and in stormwater drainages due to evaporation also likely occurs. Thus, during the early
periods of stormwater events, when stormwater sampling is specified by the permit, the discharging
stormwater would likely carry the direct condensate metals load plus impact from drainage surfaces.

The low zinc concentrations and non -detection of copper in the tributary of Brushy Creek to the south of
the site shows that stormwater discharge from the site does not affect surface water quality under normal
flow conditions. The samples were collected at upstream, adjacent, and downstream locations from the
stormwater discharge to the creek that includes Outfall 1, Outfall 2, and Outfall 3 from the Curtiss-Wright
facility.

Subject: Relief from Monthly Monitoring
Curtis -Wright Controls, Incorporated
General Permit NCG030000,
Certificate of Coverage NCG030258
Cleveland County
On August 4, 2014, our office received your report concerning the exceedances of the benchmark
values for zinc and copper. As discussed on April 8, 2014, due to repeated exceedances of zinc and
copper, it was recommended that you have your facility evaluated for sources of copper and zinc.
Please keep in mind that benchmark exceedances are NOT limit violations of permit conditions;
however, you are obligated to follow the tiered response actions outlined in your permit. Since the
renewal of the permit in November 1, 2012, the benchmarks for the parameters of zinc and copper
were exceeded during the standard semiannual monitoring events. The facility was found to be in
compliance with the tiered response actions and other conditions of the NCG030000 General
Permit. Cardno Incorporated was retained to further evaluate the facility for causes of increased
levels of zinc and copper. Cardno Incorporated identified the air conditioning units and outside
storage of metal parts which may be contributing to the exceedances of benchmark values. After
reviewing the sampling report, it appears that the condensate from the air conditioning units was the
major contributor to the elevated levels of zinc and copper.
Based on the aforementioned items, we are granting regulatory relief in the form of a collapsed Tier
2 — Tier 3 response. Upon receipt of this letter, Curtis -Wright Controls, Inc. may resume the permit
specified semi-annual analytical monitoring for the remainder of the current permit term. This
decision applies only to the copper and zinc benchmarks. A benchmark exceedance of any other
parameter listed in your permit will trigger the tiered response actions as described in the general
permit.
You must notify this office, in writing, within five business days if you become aware of any
significant source of copper or zinc at your facility that has the potential to be exposed to
stormwater. The relief granted in this letter in contingent upon the current industrial practices at
Curtis -Wright Controls, Inc. If industrial practices change and copper or zinc does become a

Subject: NPDES Stormwater Permit Coverage Renewal
Curtiss-Wright Controls Inc
COC Number NCG030258
Cleveland County
In response to your renewal application for continued coverage under stormwater General Permit NCG030000
the Division of Water Quality (DWQ) is forwarding herewith the reissued General Permit. This permit is
reissued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between the state of North Carolina and the U.S. Environmental Protection Agency, dated October
15, 2007 (or as subsequently amended).
The following information is included with your permit package:
• A new Certificate of Coverage (COC)
• A copy of General Permit NCG030000
• A copy of the Technical Bulletin for the General Permit
• Two copies of the Discharge Monitoring Report (DMR) Form
• Two copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater, and it specifies your obligations for discharge
controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself
with all the changes in the reissued permit. Your facility has six (6) months from the time of receipt of the
permit to update your current SPPP to reflect all new permit requirements. -
The first sample period of your permit begins January 1, 2013. Your facility must sample a "measureable
storm event" beginning during the periods beginning January 1 and July 1 of every year (or, if applicable,
report "No Flow," as outlined in Part III, Section E). Also, please note that Tier 3 Actions in Part II of your
permit are triggered by benchmark exceedances on four occasions beginning on the effective date of this
permit and do not count prior exceedances.
The more significant changes in the General Permit since your last COC was issued are noted either in the
Draft Permit Fact Sheet that accompanied the public notice (httR://Portal.ncdenr.org/web/wq/ws/su/current-
notices), or in the Response to Comments / Summary of Changes and Technical Bulletin documents that are
posted on the Stormwater Permitting Unit's website with the new General Permit. Please visit
http://Dortal.ncdenr.orp/web/wq/ws/su/npdessw (click on 'General Permits' tab) to review that information
for your specific General Permit carefully.

Some of the changes include:
Part II:
• Section A: The Stormwater Pollution Prevention Plan (SPPP) section, if applicable, has been updated
to the most current language of our permits. Additional conditions for specific industry sectors have
been added to the SPPP requirements in some cases. '
• Sections B, C: Failure to perform analytical stormwater monitoring may result in the Division requiring
that the permittee begin a monthly sampling scheme.
• Sections B, C. A lower TSS benchmark of 50 mg/1 for HOW, ORW, PNA and Tr Waters applies to these
more sensitive waters.
• Sections B, C: The monitoring parameter Oil & Grease (O&G) has been replaced by the parameter
Total Petroleum Hydrocarbons (TPH) for vehicle maintenance areas, and in some cases, other
analytical monitoring requirements.
• Sections B, C, D: Inability to sample due to adverse weather must be recorded in the SPPP, or in
separate on -site records if your General Permit does not require an SPPP. Adverse weather is defined
in the "Definitions" section of the permit.
• Sections B, C. The term "Representative Storm Event" has been replaced by "Measurable Storm
Event." A measurable storm event is defined in the permit.
• Section D: If the permittee fails to respond effectively to problems identified by qualitative
monitoring, DWQ may require the permittee to perform corrective action.
Please review Parts III and IV to understand the Standard Conditions of your new NPDES General Permit,
including Compliance and Liability, Reporting, Monitoring and Records requirements; Operation and
Maintenance obligations; and Definitions. Please note that all samples analyzed in accordance with the terms
of this permit must be submitted to the Division on Discharge Monitoring Report (DMR) forms available on
the Stormwater Permitting Unit's website above. DMR forms must be delivered to the Division no later than
30 days from the date the facility receives the sampling results from the laboratory. Also note that existing
permittees do not need to submit a renewal request prior to expiration unless directed by the Division.
Your coverage under the General Permit is transferable only through the specific action of DWQ. This permit
does not affect the legal requirements to obtain other permits which may be required by DENR, nor does it
relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law,
rule, standard, ordinance, order, judgment, or decree. If you have any questions regarding this permit
package, please contact the Division's Stormwater Permitting Unit at [phone].

Dear Permittee:
Your facility is currently covered for stormwater discharge under General Permit NCG030000. This permit expires
on August 31, 2002. The Division staff is currently in the process of rewriting this permit and is scheduled to have
the permit reissued by late summer of 2002. Once the permit is reissued, your facility would be eligible for
continued coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the Division of Water
Quality (DWQ) for renewal of your permit coverage. To make this renewal process easier, we are informing you in
advance that your permit will be expiring. Enclosed you will find a General Permit Coverage Renewal
Application Form. The application must be completed and returned by March 4, 2002 in order to assure continued
coverage under the general permit.
Failure to request renewal within this time period may result in a civil assessment of at least $250.00. Larger
penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility
without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to $10,000 per day.
Please note that recent federal legislation has extended the "no exposure exclusion" to all operators of industrial
facilities in any of the I I categories of "storm water discharges associated with industrial activity," (except
construction activities). If you feel your facility can certify a condition of "no exposure", i.e. the facilty industrial
materials and operations are not exposed to stormwater, you can apply for the no exposure exclusion. For additional
information contact the Central Office Stormwater Staff member listed below or check the Stormwater & General
Permits Unit Web Site at http:/fh2o.enr.state.nc.us/su/storrnwater.html
If the subject stormwater discharge to waters of the state has been terminated, please complete the enclosed
Rescission Request Form. Mailing instructions are listed on the bottom of the form. You will be notified when the
rescission process has been completed.
If you have any questions regarding the permit renewal procedures please contact Mike Parker of the Mooresville
Regional Office at 704-663-1699 or Bill Mills of the Central Office Stormwater Unit at [phone], ext. 548

Dear Mr. Felkel:
This letter is in response to your correspondence of May 16, 1994 and to verify the five
items outlined therein as follows:
1. Although the 2.63 hour event duration of the sampled storm does not meet the
definition of a representative storm event, the samples resulting from this storm event
shall be considered acceptable for fulfilling the initial monitoring requirements.
2. The required stormwater samples that were mistakenly omitted from your initial
sampling effort must be taken from another representative storm event in order to fulfill
the monitoring requirements.
3. The sample for Cyanide is incorrectly listed in NCG030000 as a composite sample.
Cyanide samples must be grab samples.
4. Facilities not storing or using Fluoride may make certification to the effect that Fluoride
is not used or stored at the facility and thus obtain a waiver from the sampling
requirement.
5. If your facility performs metal finishing operations, manufactures semiconductors,
manufacture electronic crystals, or manufactures cathode ray tubes then Total Toxic
Organics (TTO) monitoring is required. If your facility is required to sample TTO, a
solvent management plan may be developed, implemented, and incorporated into the
Stormwater Pollution Prevention Plan and a request may be filed with DEM to waive
TTO monitoring.
If you have any questions, please feel free to contact me at [phone] ext. 537.

Re. Stormwater Permit COC NCG030258 _'
Dear Ms. Briggs: - =
As discussed during our telephone conversation on May 9, 1994, Curtiss-Wright Flight Systems conducted
stormwater sampling on March 10, 1992 as part of our stormwater permit application. Our stormwater
permit, issued on October 22, 1993, contained some stormwater monitoring requirements which were not
met during the March 10, 1992 sampling. The storm event sampled had a duration of 2.63 hours
(representative event is greater than 3 hours) and total precipitation was 0.3 inches. Curtiss-Wright did not
sample for Iron, Fluoride, or Total Toxic Organics. An Oil and Grease sample was not taken at one
discharge point and Cyanide samples were taken as grabs.
Please confirm the following:
• That the sampling completed on March 10, 1992 is valid even though the storm event duration was
2.63 hours.
• That we should sample another representative storm event for Iron and for the Oil and Grease sample
that was not taken.
• The sample type for Cyanide should be Grab and not Composite as is listed on General Permit
NCG030000.
• Curtiss-Wright has the option of sampling for Fluoride or certifying that it is not used or stored at our
facility.
• Curtiss-Wright has the option of sampling for Total Toxic Organics or developing a solvent
management plan and requesting to DEM that monitoring of Total Toxic Organics be waived.
if you need any further information please contact me at [phone]. Thank you for your assistance in
this matter.

Subject: NPDES Stormwater Permit Renewal

COC Number NCG030258
Cleveland County
Dear Permittee:
Your facility is currently covered for stormwater discharge under General Permit NCG030000. This permit expires
on August 31, 2002. The Division staff is currently in the process of rewriting this permit and is scheduled to have
the permit reissued by late summer of 2002. Once the permit is reissued, your facility would be eligible for
continued coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the Division of Water
Quality (DWQ) for renewal of your permit coverage. To make this renewal process easier, we are informing you in
advance that your permit will be expiring. Enclosed you will find a General Permit Coverage Renewal
Application Form. The application must be completed and returned by March 4, 2002 in order to assure continued
coverage under the general permit.
Failure to request renewal within this time period may result in a civil assessment of at least $250.00. Larger
penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility
without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to $10,000 per day.
Please note that recent federal legislation has extended the "no exposure exclusion" to all operators of industrial
facilities in any of the 11 categories of "storm water discharges associated with industrial activity," (except
construction activities). If you feel your facility can certify a condition of "no exposure", i.e. the facilty industrial
materials and operations are not exposed to stormwater, you can apply for the no exposure exclusion. For additional
information contact the Central Office Stormwater Staff member listed below or check the Stormwater & General
Permits Unit Web Site at http://h2o.enr.state.nc.us/su/stormwater.html
If the subject stormwater discharge to waters of the state has been terminated, please complete the enclosed
Rescission Request Form. Mailing instructions are listed on the bottom of the form. You will be notified when the
rescission process has been completed.
If you have any questions regarding the permit renewal procedures please contact Mike Parker of the Mooresville
Regional Office at 704-663-1699 or Bill Mills of the Central Office Stormwater Unit at [phone], ext. 548
