Subject: Compliance Evaluation Inspection - Stormwater
Permit # NCG070189
Wilkes County
Dear Mr. Hurley:
On December 8, 2011 a Compliance Evaluation Inspection was performed by George Smith, of this office. Mr.
Dan Hurley was present for the inspection.
Permit
Previously, Certain Teed was covered under the NCG210000 which applies to industries engaged in Timber
Products, which does not fit the industrial classification for this permit.
On August 27, 2010 the certificate of coverage for NPDES General Permit NGG070000 was issued, which is
primarily for industries engaged in: Stone, Clay, Glass, and Concrete Products. Qualitative Monitoring is
required per Part II, Section B. Please insure the monitoring for this requirement is performed as required in the
permit.
In a letter from the Division dated August 27, 2010, analytical monitoring is required for COD, TSS, and pH.
This is further discussed in the section, Self -Monitoring Program, of this report.
Records & Reports
All records, reports, and the SPPP are available as required per the permit.
Facility Site Review
The samples were collected at the specified locations, and the site is well kept.
Pipes 006 A & B were observed in the manhole in front of the office. The stormwater from Certain Teed is
segregated from the stormwater from Louisiana Pacific (LP).
There is no On -Site Vehicle Maintenance at this facility.

Self -Monitoring Program
As discussed the following Outfails were sampled for COD, TSS, and pH:
Outfall #001 - Stormwater draining from the storage yard to a vegetative ditch and discharging to the
Yadkin River.
Outfall #002 - Stormwater draining from an adjacent storage area and discharging to the Yadkin River.
Outfall 9006A — Stormwater from the upper most pipe in the manhole. Stormwater from roof drains.
Outfall 9006B — Stormwater from the pipe below the upper most pipe. Stormwater from the west side of
the building.
Analytical sampling events were performed for each outfall during March, September, and November of 2011.
The results showed that all samples were less than the benchmark value for COD, TSS, and pH.
In accordance_ with the Division letter dated August 27 2010, this office considers all analytical sampling -to be
fulfilled. Therefore Certain Teed shall immediately revert to the qualitative sampling and comply with all Terms
& Conditions as defined in the NPDES General Permit NCG07000O.
The compliance evaluation inspection is satisfactory. Mr. Hurley is implementing the stormwater program in an
outstanding manner. If you have any questions please contact George Smith or me at [phone].

*Note: If a value is in excess of the benchmark, or outside the benchmark range (for pH), you must implement the Tier 1 or Tier 2 responses in the General Permit.
'Monitoring is required only it the facility stores exposed piles of sawdust, wood chips, bark, mulch, or other similar material on site for longer than seven (7) days.
A facility that does not retain exposed (either exposed to incident precipitation or exposed to stormwater run on) piles of sawdust, wood chips, bark, mulch, or other

any facility from qualitative monitoring of SDOs. )
If the facility removes such materials within seven days to meet the monitoring exemption, the Permittee shall record and maintain in the facility's SPPP a log
which documents, at a minimum, the dates when material is generated and removed, how removed, and by whom. The log must be sufficient to establish that no

Subject: Compliance Evaluation Inspection - Stormwater
Permit # NCG070189
Wilkes County
Dear Mr. Hurley:
Resources
Dee Freeman
Secretary
On December 8, 2011 a Compliance Evaluation Inspection was performed by George Smith, of this office. Mr.
Dan Hurley was present for the inspection.
Permit
Previously, Certain Teed was covered under the NCG210000 which applies to industries engaged in Timber
Products, which does not fit the industrial classification for this permit.
On August 27, 2010 the certificate of coverage for NPDES General Permit NGG070000 was issued, which is
primarily for industries engaged in: Stone, Clay, Glass, and Concrete Products. Qualitative Monitoring is
required per Part II, Section B. Please insure the monitoring for this requirement is performed as required in the
permit.
In a letter from the Division dated August 27, 2010, analytical monitoring is required for COD, TSS, and pH.
This is further discussed in the section, Self -Monitoring Program, of this report.
Records & Reports
All records, reports, and the SPPP are available as required per the permit.
Facility Site Review
The samples were collected at the specified locations, and the site is well kept.
Pipes 006 A & B were observed in the manhole in front of the office. The stormwater from Certain Teed is
segregated from the stormwater from Louisiana Pacific (LP).
There is no On -Site Vehicle Maintenance at this facility.

Self -Monitoring Program
As discussed the following Outfalls were sampled for COD, TSS, and pH:
Outfall #001 - Stormwater draining from the storage yard to a vegetative ditch and discharging to the
Yadkin River.
Outfall #002 - Stormwater draining from an adjacent storage area and discharging to the Yadkin River.
Outfall #006A — Stormwater from the upper most pipe in the manhole. Stormwater from roof drains.
Outfall #006B — Stormwater from the pipe below the upper most pipe. Stormwater from the west side of
the building.
Analytical sampling events were performed for each outfall during March, September, and November of 2011.
The results showed that all samples were less than the benchmark value for COD, TSS, and pH.
In accordance with the Division letter dated August 27 2010, this office considers all analytical samplig to be
fulfilled. Therefore Certain Teed shall immediately revert to the qualitative sampling and comply with all Terms
& Conditions as defined in the NPDES General Permit NCG070000:
The compliance evaluation inspection is satisfactory. Mr. Hurley is implementing the stormwater program in an
outstanding manner. If you have any questions please contact George Smith or me at [phone].

'Monitoring is required only if the facility stores exposed piles of sawdust, wood chips, bark, mulch, or other similar material on site for longer than seven (7) days.
A facility that does not retain exposed (either exposed to incident precipitation or exposed to stormwater run on) piles of sawdust, wood chips, bark, mulch, or other
similar material on site for more than seven (7) days before removing the material is not required to monitor for the parameters in Table 1 of the General Permit. If
at any time the material is not removed within this time frame, the facility must begin analytical monitoring immediately. (Reminder: This condition does not exempt
any facility from qualitative monitoring of SDOs.)
If the facility removes such materials within seven days to meet the monitoring exemption, the Permittee shall record and maintain in the facility's SPPP a log
which documents, at a minimum, the dates when material is generated and removed, how removed, and by whom. The log must be sufficient to establish that no
materials were exposed for longer than seven days. For record -keeping purposes, the Permittee may also maintain in the SPPP this form with the signed
certification below:

Re: OCTOBER AND NOVEMBER 2010 - STORMWATER DISCHARGE OUTFALL (SDO) MONITORING REPORT
Dear Sir/Madam:
I am submitting the OCTOBER and NOVEMBBR 2010- STORMWATER DISCHARGE OUTFALL (SDO) MONITORING
REPORTS for the CertainTeed Corp. Roaring River Facility. These reports cover.
1.) Samples collected on 10/25/10. No value outside the Benchmark values for TSS and COD for sample point 001, 002, 006A,
and 006E are reported.
The 10/25/10 sampling showed pH for sample points 001, 002 and 006A was within the benchmarks. However, the pH for
sample point 006B was 9.2.
2.) Samples collected on 11/15/10: Due to low flow only sampling points 006A and 0006 were sampled. The pH for sample point
006A was 9.2. All other parameters were within benchmarks
The over bench mark pH readings from sample points 06A&B were investigated and the root cause was determined to
be residual Portland cement on the roof structure of the facility due to a recent bucket elevator malfunction. This residual
caused the pH of the sample to be elevated. We will be cleaning the structure to remedy this discrepancy.
Thank you for your assistance in this matter. If you have any questions regarding this request, please contact Dan Hurley at
336-696-2007 Ext 234.

*Note: If a value is in excess of the benchmark, or outside the benchmark range (for pH), you must implement the Tier 1 or Tier 2 responses in the General Permit.
'Monitoring is required only if the facility stores exposed piles of sawdust, wood chips, bark, mulch, or other similar material on site for longer than seven (7) days.
A facility that does not retain exposed (either exposed to incident precipitation or exposed to stormwater run on) piles of sawdust, wood chips, bark, mulch, or other
similar material on site for more than seven (7) days before removing the material is not required to monitor for the parameters in Table 1 of the General Permit. If
at any time the material is not removed within this time frame, the facility must begin analytical monitoring immediately. (Reminder: This condition does not exempt
any facility from qualitative monitoring of SDOs.)
If the facility removes such materials within seven days to meet the monitoring exemption, the Permittee shall record and maintain in the facility's SPPP a log
which documents, a minimum, the dates wheR material is generated and removed, how removed, and by whom. The log must be sufficient to establish that no
materials were expose for longer than seven das. For record -keeping purposes, the Permittee may also maintain in the SPPP this form with the signed
certification below:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit requirement for analytical monitoring,
certify that to the best of my knowledge and belief, no piles of,sawdust, wood chips, bark, mulch &,ether similar materials were stored exposed (either to
incident precipitatiomor to stormwater run on) for longer than seven (7) days before removal since filing the last discharge monitoring report."
