S&ME Project No. 1411-07-049
Dear Mr. Ramsey:
S&ME, Inc. has completed the September 2007 stormwater sampling event at the Saint-
Gobain Abrasives facility in Arden, North Carolina in accordance with S&ME Proposal
ENV-084-07 dated April 9, 2007. The stormwater sample was collected on September
14, 2007 from the sole outfall located along the western shoulder of Beale Road. The
collected stormwater sample was submitted to Pace Analytical Services, Inc. for analysis
for:
• pH
• Total Suspended Solids (TSS)
• Oil & grease
A copy of the laboratory report and corresponding chain -of -custody is attached.
Using the Site & Grading Plan provided by Mr. Ramsey with Saint-Gobain, S&ME
calculated the approximate area of impervious surfaces that drain to this outfall to be
80,915 square feet. Based on data from the Asheville Regional Airport weather station
(http://www.ne-climate.ncsu.edu), 3.4 inches of precipitation occurred on September 14,
2007. A copy of the data is attached. Using this data, S&ME estimates that
approximately 0.17 million gallon (MG) of runoff occurred during the September 14,
2007 rain event. Calculations used to obtain the area of impervious surfaces and total
flow is attached.
S&ME has completed the Stormwater Discharge Outfall Monitoring Report (i.e.
quantitative report) and the Stormwater Discharge Outfall Qualitative Monitoring Report

1 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic crystals, or
manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the facility subject
to the requirement to sample (for metal finishing use the definitiowas found in 40 CFR 433.1 l; for semiconductor manufacture use the definition as found in 40 CFR 469.12; for
electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469.31).
Facilities that develop a solvent management plan to be incorporated into the Stormwater Pollution Prevention Plan may make a request to DWQ that monitoring of total toxic
organics be waived. The solvent management plan shall include a list of the total toxic organic compounds used; the method of disposal used instead of dumping, such as
reclamation, contract hauling, or incineration; and the procedures for assuring that toxic organics do not routinely spill or leak into the stormwater. For those facilities allowed such a
waiver, the discharger shall include the following signed certification statement on the discharge monitoring report:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), I
certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater
runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the solvent management plan included in the
Stormwater Pollution Prevention Plan."

Refercnce: Stormwater Sampling Report
Saint-Gobain Abrasives -
65 Beale Road
Arden, North Carolina
S&ME Project No. 1411-07-049
Dear Mr. Ramsey:
S&ME, Inc. has completed the July 2007 stormwater sampling event at the Saint-Gobain Abrasives
facility in Arden, North Carolina in accordance with S&ME Proposal ENV-084-07 dated April 9, 2007.
The stormwater sample was collected on July 10, 2007 from the sole outfall located along the western
shoulder of Beale Road. The collected stormwater sample was submitted to Pace Analytical Services,
Inc. for analysis for:
• pH
• Total Suspended Solids (TSS)
• Oil & grease
A copy of the laboratory report and corresponding chain -of -custody is attached.
Using the Site & Grading PIan provided by Mr. Ramsey with Saint-Gobain, S&ME calculated the
approximate area of impervious surfaces that drain to this outfall to be 80,915 square feet. Based on data
from the Asheville Regional Airport weather station (htt ://www.nc-cIimate.nesu.edu), 0.88 inches of
precipitation occurred on July 10, 2007 over a 2 hour period. A copy of the data is attached. Using this
data, S&ME estimates that approximately 0.53 million gallon (MG) of runoff occurred during the July
10, 2007 rain event. Sampling calculations used to obtain the area of impervious services and total flow
are attached.

1 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic crystals, or
manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the facility subject
to the requirement to sample ( for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor manufacture use the definition as found in 40 CFR 469,12; for
electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469.31).
Facilities that develop a solvent management plan to be incorporated into the Stormwater Pollution Prevention Plan may make a request to DWQ that monitoring of total toxic
organics be waived. The solvent management plan shall include a list of the total toxic organic compounds used; the method of disposal used instead of dumping, such as
reclamation, contract hauling, or incineration; and the procedures for assuring that toxic organics do not routinely spill or leak into the stormwater. For those facilities allowed such a
waiver, the discharger shall include the following signed certification statement on the discharge monitoring report:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), I
certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater
runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the solvent management plan included in the
Stormwater Pollution Prevention Plan."

S&ME Project No. 1411-07-049
Dear Mr. Ramsey:
S&ME, Inc. has completed the April 2007 stormwater sampling event at the Saint-Gobain Abrasives
facility in Arden, North Carolina in accordance with S&ME Proposal ENV-084-07 dated April 9, 2007.
The stormwater sample was collected on April 19, 2007 from the sole outfall located along the western
shoulder of Beale Road. The collected stormwater sample was submitted to Pace Analytical Services,
Inc. for analysis for:
• pH
• Total Suspended Solids (TSS)
• Metals
• Cyanide
• Phenolics
• Semi -volatile organic compounds by Method 625
• Volatile organic compounds by Method 624
• Oil & grease
• pesticides'and polychlorinated biphenyl (PCB) by Method 608
A copy of the laboratory report and corresponding chain -of -custody is attached.
Using the Site & Grading Plan provided by Mr. Ramsey with Saint-Gobain, S&ME calculated the
approximate area of impervious surfaces that drain to this outfall to be 80,915 square feet. Based on data
from the Asheville Regional Airport weather station (http://www.nc-cliiiiate.ncsu.edu), 0.4107 inches of
precipitation occurred on April 19, 2007. A copy of the data is attached. Using this data, S&ME

1 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic crystals, or
manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the facility subject
to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor manufacture use the definition as found in 40 CFR 469.12; for
electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469.31).
Facilities that develop a solvent management plan to be incorporated into the Stormwater Pollution Prevention Plan may make a request to DWQ that monitoring of total toxic
organics be waived. The solvent management plan shall include a list of the total toxic organic compounds used; the method of disposal used instead of dumping, such as
reclamation, contract hauling, or incineration; and the procedures for assuring that toxic organics do not routinely spill or leak into the stormwater. For those facilities allowed such a
waiver, the discharger shall include the following signed certification statement on the discharge monitoring report:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), I
certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater
runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the solvent management plan included in the
Stormwater Pollution Prevention Plan."

Attention: Mr. Keith A. Ramsey
Environmental, Health, and Safety Manager
Reference: September 2007 Stormwater Sampling Report
Saint-Gobain Abrasives
65 Beale Road
Arden, North Carolina
S&ME Project No. 1411-07-049
Dear Mr. Ramsey:
S&ME, Inc. has completed the September 2007 stormwater sampling event at the Saint-
Gobain Abrasives facility in Arden, North Carolina in accordance with S&ME Proposal
ENV-084-07 dated April 9, 2007, The stormwater sample was collected on September
14, 2007 from the sole outfall located along the western shoulder of Beale Road. The
collected stormwater sample was submitted to Pace Analytical Services, Inc. for analysis
for:
• PH
• Total Suspended Solids (TSS)
• Oil & grease
A copy of the laboratory report and corresponding chain -of -custody is attached.
Using the Site & Grading Plan provided by Mr. Ramsey with Saint-Gobain, S&ME
calculated the approximate area of impervious surfaces that drain to this outfall to be
80,915 square feet. Based on data from the Asheville Regional Airport weather station
(htt :1/www.ne-climate.nesu.edu), 3.4 inches of precipitation occurred on September 14,
2007. A copy of the data is attached. Using this data, S&ME estimates that
approximately 0.17 million gallon (MG) of runoff occurred during the September 14,
2007 rain event. Calculations used to obtain the area of impervious surfaces and total
flow is attached.
S&ME has completed the Stormwater Discharge Outfall Monitoring Report (i.e.
quantitative report) and the Stormwater Discharge Outfall Qualitative Monitoring Report

l Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic crystals, or
manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the facility subject
to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor manufacture use the definition as found in 40 CFR 469.12; for
electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469.3 0.
Facilities that develop a solvent management plan to be incorporated into the Stormwater Pollution Prevention Plan may make a request to DWQ that monitoring of total toxic
organics be waived. The solvent management plan shall include a list of the total toxic organic compounds used; the method of disposal used instead of dumping, such as
reclamation, contract hauling, or incineration; and the procedures for assuring that toxic organics do not routinely spill or leak into the stormwater. For those facilities allowed such a
waiver, the discharger shall include the following signed certification statement on the discharge monitoring report:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), I
certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater
runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the solvent management plan included in the
Stormwater Pollution Prevention Plan."

Dear Mr. Owen:
The Division has'reviewed your submittal of the No -Exposure Certification for Exclusion from NPDES
Stormwater Permitting form, which we received on July 17, 2006. Based on your submittal and signed
certification of no exposure at the above referenced facility, the Division is granting your certification as
provided for under 40 CFR 126.22(g), which is incorporated by reference in North Carolina regulations, and is
hereby rescinding your former Certificate of Coverage NCG030160.
Please note that by our acceptance of your no exposure certification, you are obligated to maintain no
exposure conditions at your facility. If conditions change such that your facility can no longer qualify for a no -
exposure exclusion, you are obligated to immediately obtain NPDES permit coverage for your stormwater
discharge. Otherwise, the discharge becomes subject to enforcement as an un-permitted discharge. Your
conditional no -exposure exclusion expires in five years (August 31, 2011). At that time you must re -certify
with the Division, or obtain NPDES permit coverage for any stormwater discharges from your facility.
Your certification of no exposure does not affect your facility's legal requirements to obtain environmental
permits that may be required under other federal, state, or local regulations or ordinances.
1f you have any questions or need further information, please contact Sarah Young at [phone], ext.
502, or at [e-mail].

FORM ``�' ��� NO EXPOSURE CERTIFICATION for Exclusion from
3510-11
NPDES Storm Water Permitting
Submission of this No Exposure Certification constitutes notice that the entity identified in Section A does not require permit authorization for its storm water
discharges associated with industrial activity in the State identified in Section B under EPA's Storm Water Multi -Sector General Permit due to the existence
of a condition of no exposure.
A condition of no exposure exists at an industrial facility when all industrial materials and activities are protected by a storm resistant shelter to prevent
exposure to rain, snow, snowmen, and/or runoff_ Industrial materials or activities include, but are not limited to, material handling equipment or activities.
Industrial machinery, raw materials, Intermediate products, by-products, final products, or waste products. Material handling activities Include the storage,
loading and unloading, transportation, or conveyance of any raw material, intermediate product, final.product or waste product. A storm resistant shelter is
not required for the following industrial materials and activities-
- drums, barrels, tanks, and similar containers that are tightly sealed, provided those containers are not deteriorated and do not leak. "Sealed'
means banded or otherwise secured and without operational taps or valves:
- adequately maintained vehicles used in material handling; and
- final products, other than products that would be mobilized in stem water discharges (e.g.. rode salt).
A No Exposure Certification must be provided for each facility qualifying for the no exposure exclusion. In addition, the exclusion from NPDES permitting is
available on a facility -wide basis only, not for individual outfalis. If any industrial activities or materials are or will be exposed to precipitation, the facility is
not eligible for the no exposure exclusion.
By signing and submitting this No Exposure Certification form, the entity in Section A is certifying that a condition of no exposure exists at its facility or site,
and is obligated to comply with the terms and conditions of 40 CFR 122.26(g),
ALL INFORMATION MUST BE PROVIDED ON THIS FORM.
