STORMWATER PERMITTING
Subject: Spring, 2019 Semi-annual Monitoring Report, NPDES Permit NCS000101
Dear Stormwater Section:
Enclosed are two copies of the Spring, 2019 semi-annual analytical monitoring report for NPDES
Permit No. NCS000101, issued December 1, 2014 to International Paper's Riegelwood Mill. Lab
results are included, as well as a mill stormwater basin map. Analytical samples were collected on
March 1 and May 12, 2019 for Basin T. Analytical results appear in the attached data table. During
the Spring semester of 2019, drought conditions only allowed collection of two Tier 2 samples, and
narrow representative rainfall windows prevented sampling the Tier 1 outfalls B, E, and I.
Analytical Results and Corrective Actions: In the Fall 2018 sampling event on December 14, the
runoff quality for Basin T was above the permitted benchmark for TSS and COD. A utility cut
exposing soil under the pavement was repaved, and was the only observed potential contributor.
Inspections and investigation of Basin T are ongoing in an effort to improve runoff quality.
Basins B, E, and I:
No flow during daylight hours and safe sampling conditions.
Basin T:
Basin T is a Tier 2 outfall; during short rain events Basin T was prioritized and sampled on March 1
and May 12, 2019. The March 1 TSS was above the permit benchmark at 312 mg/L, and COD was
likewise above the benchmark at 290 mg/L. BOD and pH were within benchmarks. The May 12
sample was easily within the benchmark for all parameters. A multi -department investigation
revealed that truck traffic has been rerouted due to traffic safety concerns, and all log trucks from the
wet woodyard now enter through a dirt driveway instead of from a paved road. This change has
increased dirt and debris tracked into Basin T by the trucks. A rock apron recently installed where
the dirt road meets Basin T pavement is helping somewhat, but the problem persists. Additional
maintenance measures, such as frequent removal of buildups from road edges where the sweeper
cannot go, and eliminating runoff flow restrictions, are being examined.

STORMWATER PERMITTING
Subject: Spring, 2019 Semi-annual Monitoring Report, NPDES Permit NCS000101
Dear Stormwater Section
Enclosed are two copies of the Spring, 2019 semi-annual analytical monitoring report for NPDES
Permit No. NCS000101, issued December 1, 2014 to International Paper's Riegelwood Mill. Lab
results are included, as well as a mill stormwater basin map. Analytical samples were collected on
March 1 and May 12, 2019 for Basin T. Analytical results appear in the attached data table. During
the Spring semester of 2019, drought conditions only allowed collection of two Tier 2 samples, and
narrow representative rainfall windows prevented sampling the Tier 1 outfalls B, E, and I.
Analytical Results and Corrective Actions: In the Fall 2018 sampling event on December 14, the
runoff quality for Basin T was above the permitted benchmark for TSS and COD. A utility cut
exposing soil under the pavement was repaved, and was the only observed potential contributor.
Inspections and investigation of Basin T are ongoing in an effort to improve runoff quality.
Basins B, E, and I:
No flow during daylight hours and safe sampling conditions.
Basin T:
Basin T is a Tier 2 outfall; during short rain events Basin T was prioritized and sampled on March 1
and May 12, 2019. The March 1 TSS was above the permit benchmark at 312 mg/L, and COD was
likewise above the benchmark at 290 mg/L. BOD and pH were within benchmarks. The May 12
sample was easily within the benchmark for all parameters. A multi -department investigation
revealed that truck traffic has been rerouted due to traffic safety concerns, and all log trucks from the
wet woodyard now enter through a dirt driveway instead of from a paved road. This change has
increased dirt and debris tracked into Basin T by the trucks. A rock apron recently installed where
the dirt road meets Basin T pavement is helping somewhat, but the problem persists. Additional
maintenance measures, such as frequent removal of buildups from road edges where the sweeper
cannot go, and eliminating runoff flow restrictions, are being examined.

DENR-LAND QUALITY
STORMWATER PERMITTING
Subject: Fall, 2018 Semi-annual Monitoring Report, NPDES Permit NCS000101
Dear Surface Water Protection Section:
- Enclosed are two copies of the Fall 2018 semi-annual analytical monitoring report for NPDES Permit
No. NCS000101, issued December 1, 2014 to International Paper's Riegelwood Mill. Lab results are
included, as well as a mill stormwater basin map. Analytical samples were collected on December
14, 20, and 28, 2018 for Basins B, E, 1, and T. Basin T was added to the mill SWPPP in 2015 due to
construction of a new scalehouse for wood trucks, thus there is no representative status for Basin T.
As we have done for previous new basins, full analytical sampling will be conducted for several
semesters, and representative status will be requested after quality data is established. Analytical
results were received from the contract lab Envirochem on January 16, 2018, and appear in the
attached data table.
Analytical Results and Corrective Actions: In the Fall 2018 sampling event on December 14, the
runoff quality for Basins B and E was excellent, with all parameters well within the permit
benchmarks. Both these basins were approved by NCDEQ to return to Tier 1 status on May 8, 2018.
Basin I did not meet the benchmark for TSS, and Basin T did not meet the benchmarks for COD and
TSS. Detailed information for each basin is outlined below.
Basin 13:
Basin B is in excellent condition following extensive improvements in late 2017 and early 2018, with
no issues noted. Basin B is a Tier 1 outfall, operating under the semi-annual sampling schedule.
Basin F:
Stormwater quality is also very good in Basin E, a Tier 1 outfall. Hurricane Florence caused
extensive damage in Basin E; all repairs were completed expeditiously, and the outfall is in very good
condition. Stormwater BMPs are in place and intensive housekeeping measures continue to ensure
high runoff quality.
S/Groups/Environmcutal/Stormwater/Reports/2017,18 rpts/Fall 2018/Anal/Cvr Ur

(•' Basin I:
Basin I analytical results for Fall, 2018 were within the permit benchmarks with the exception of
TSS. Initial investigation did not yield a definitive source for the high result, and the outfall was
resampled on December 20 to verify results. The second sample also exceeded the TSS benchmark,
and investigation intensified. A buildup of sediment in the line was revealed using a camera. The
line was cleaned, and in addition, a ring of Siltsoxx was added to slow and filter outfall runoff. A
third sample on December 28 showed improvement, with results within the benchmark. It is our
understanding that once a benchmark exceedance is corrected and acceptable runoff quality is
proven, as happened in the Fall, 2017 exceedance; that issue is considered completed and closed, and
is no longer included when totaling any subsequent exceedances for Tiered qualifications.
Consequently, the current benchmark exceedance at Basin I is considered the first Tier 1 exceedance
for TSS for Basin I, and Basin I remains a Tier I outfall. .
Basin T:
In Basin T, both COD and TSS results fell outside the benchmarks, despite ongoing, intensive
housekeeping efforts. The area had just been maintained when the December,14 sample was taken,
and the exceedances were not expected. A second sample was pulled on December 20, with the same
high results. Extensive investigation involving several mill departments resulted in a plan for several
corrective actions, which are currently underway. The adjoining wet woodyard, which is unpaved
and has heavy truck traffic, was identified as a new potential contributing factor to both high TSS and
COD. This potential source of solids had not been previously observed and could be an unexpected
result of Hurricane Florence and wet weather in general. The wetyard is updating road maintenance
by adding a rock apron adjoining Basin T pavement. In response to that finding, mill housekeeping
efforts will be expanded to include the pavement immediately adjoining the wetyard. In addition, a
recent construction project left a cut through the pavement, exposing soil in another area adjoining
Basin T. Siltsoxx surrounded the cut during construction, but were no longer effective. The project
is finished now, and this cut will be re -paved, eliminating a potential source for the high TSS. Basin
T is moved to Tier 2 and monthly sampling, beginning in February.
I certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or
persons who manage the system, or those persons directly responsible for gathering the information,
the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I
am aware that there are significant penalties for submitting false information, including the
possibility of fines and imprisonment for knowing violations.

Subject: Fall, 2018 Semi-annual Monitoring Report, NPDES Permit NCS000101
Dear Surface Water Protection Section:
Enclosed are two copies of the Fall 2018 semi-annual analytical monitoring report for NPDES Permit
No. NCS000101, issued December], 2014 to International Paper's Riegelwood Mill. Lab results are
included, as well as a mill stormwater basin map. Analytical samples were collected on December
14, 20, and 28, 2018 for Basins B, E, I, and T. Basin T was added to the mill SWPPP in 2015 due to
construction of a new scalehouse for wood trucks, thus there is no representative status for Basin T.
As we have done for previous new basins, full analytical sampling will be conducted for several
semesters, and representative status will be requested after quality data is established. Analytical
results were received from the contract lab Envirochem on January 16, 2018, and appear in the
attached data table.
Analytical Results and Corrective Actions: In the Fall 2018 sampling event on December 14, the,
runoff quality for Basins B and E was excellent, with all parameters well within the permit
benchmarks. Both these basins were approved by NCDEQ to return to Tier 1 status on May 8, 2018.
Basin I did not meet the benchmark for TSS, and Basin T did not meet the benchmarks for COD and
TSS. Detailed information for each basin is outlined below.
Basin 13:
Basin 13 is in excellent condition following extensive improvements in late 2017 and early 2018, with
no issues noted. Basin 13 is a Tier 1 outfall, operating under the semi-annual sampling schedule.
Basin E:
Stormwater quality is also very good in Basin E, a Tier 1 outfall. Hurricane Florence caused
extensive damage in Basin E; all repairs were completed expeditiously, and the outfall is in very good
condition. Stormwatcr BMPs are in place and intensive housekeeping measures continue to ensure
l- high runoff quality.
S/Groups/Environmental/Storn»vater/Reports/2017,18 rpts/Fall 2018/Anal/Cvr Ur

Basin 1:
Basin I analytical results for Fall, 2018 were within the permit benchmarks with the exception of
TSS. Initial investigation did not yield a definitive source for the high result, and the outfall was
resampled on December 20 to verify results. The second sample also exceeded the TSS benchmark,
and investigation intensified. A buildup of sediment in the line was revealed using a camera. The
line was cleaned, and in addition, a ring of Siltsoxx was added to slow and filter outfall runoff. A
third sample on December 28 showed improvement, with results within the benchmark. It is our
understanding that once a benchmark exceedance is corrected and acceptable runoff quality is
proven, as happened in the Fall, 2017 exceedance, that issue is considered completed and closed, and
is no longer included when totaling any subsequent exceedances for Tiered qualifications.
Consequently, the current benchmark exceedance at Basin I is considered the first Tier 1 exceedance
for TSS for Basin I, and Basin I remains a Tier 1 outfall. .
Basin T:
In Basin T, both COD and TSS results fell outside the benchmarks, despite ongoing, intensive
housekeeping efforts. The area had just been maintained when the December 14 sample was taken,
and the exceedances were not expected. A second sample was pulled on December 20, with the same
high results. Extensive investigation involving several mill departments resulted in a plan for several
corrective actions, which are currently underway. The adjoining wet woodyard, which is unpaved
and has heavy truck traffic, was identified as a new potential contributing factor to both high TSS and
COD. This potential source of solids had not been previously observed and could be an unexpected
result of Hurricane Florence and wet weather in general. The wetyard is updating road maintenance
by adding a rock apron adjoining Basin T pavement. In response to that finding, mill housekeeping
efforts will be expanded to include the pavement immediately adjoining the wetyard. In addition, a
recent construction project left a cut through the pavement, exposing soil in another area adjoining
Basin T. Siltsoxx surrounded the cut during construction, but were no longer effective. The project
is finished now, and this cut will be re -paved, eliminating a potential source for the high TSS. Basin
T is moved to Tier 2 and monthly sampling, beginning in February.
