Subject: NPDES Stormwater Permit Coverage Renewal
Gem Fabrication of North Carolina Inc
COC Number NCG030461
Rowan 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 COG was issued are noted either in the
Draft Permit Fact Sheet that accompanied the public notice (http:/Iportal.ncdenr.orp,/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:/Iportal.ncdenr.org/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/I for HQW, 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].
Sincerely,,

Dear Permittee:

Acting Director
Division of Water Quality
December 27, 2001
Subject: NPDES Stormwater Permit Renewal
GRINNEL FIRE PROTECTION SYSTEM
COC Number NCG030461
Rowan County
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.htmi
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

We are in receipt of your .July 17, 2017 letter requesting relief from monthly monitoring at the Ceveland facility. Based on the site
inspection May 4, 2017 and the information provided the facility is in compliance with the tiered response actions and other conditions of
the NCG030000 General Permit. Therefore, the Division is granting regulatory relief from the Tier responses. Upon receipt of this letter, the
subject facility may resume the permit specified semi-annual analytical monitoring for the remainder of the current permit term which
expires on October 31, 2017. 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. When the new general permit is
issued you will need to review the new copper and zinc benchmarks and follow the applicable relief measures if required.
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 is contingent upon the current
industrial practices at GEM Fabrication of North Carolina Inc. If industrial practices change and copper or zinc does become a
significant stormwater exposure risk or significant zinc or copper values have been recorded during regular sampling events, then this
office reserves the right to withdraw this decision and reinstate the permit specified tiered response or other actions that may be
warranted by the new set of circumstances.
Please retain and append this letter to your Stormwater Pollution Prevention Plan (SPPP) or permit, If you have any

Inspection Summary -
The inspection was a result of requested technical assistance regarding sources of copper and zinc. Based on the site visit
and data review I would recommend monitoring relief for only copper and zinc for the duration of the existing permit. Copper
is not used in the metal fire protection fabrication process and zinc has been found above the benchmark in rainwater. Also,
galvanized pipe is stored outside in the same way it would be installed in commercial use. Control measures have been
implemented and have helped reduce levels, but not to the extent required.

I am writing this letter on behalf of Gem Fabrication, located in Cleveland, NC based off
of our meeting at the facility on May 41b, 2017. Shamrock has been retained to help
maintain the storm water permit and aid in any way possible. Shamrock performed an
extensive storm water inspection at the beginning of our contract in October, 2015 and
found a few areas of concern that was soon corrected; however we continued to see
elevated Copper and Zinc levels. Once it was determined that our areas of concern were
not the problem with our elevated levels we implemented barrier controls and carbon
booms at all storm water drains in hopes of reducing our Copper and Zinc levels; but to
no avail. Gem Fabrication has spent well over $50,000.00 dollars in an effort to be
compliant with our company mission statement and to be a good environmental steward.
We continue to exceed the benchmark standards, however; being relatively close to
compliance we are asking for help and possible return to the semi-annual sampling. We
are under the belief that we have a finished product (pipe) that has not been altered or
changed once received, therefore exempting us from the metal fabrication storm water
requirements.
We have noted the following:
• Tap water copper levels exceed our current benchmark requirements
• Added sand to try and help mitigate suspended solids
• Shamrock pressure washed all roof and appurtenances to help with any potential
runoff to outfall locations
• Built rainwater collection boxes to determine metal content
• Gem Fab has installed hay bales and carbon socks around drains to no avail
Shamrock built a sediment basin to help settle`any potential suspended solids
carry-over
• Shamrock installed floc logs specifically designed to remove Zinc and Copper
• Please find attached copies of inspections, analytical done in conjunction with
required sampling and countermeasures enacted.

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 1 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/storrnwater.htmi
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
