Subject: Spring, 2020 Semi-annual Monitoring Report,NPDES Permit NCS000101
Dear Stormwater Section:
Enclosed are two copies of the Spring, 2020 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
April 13, May 5, and June 10, 2020. Analytical results appear in the attached data table. During the
Spring semester of 2020, weather conditions during work hours allowed collection of three Tier 2
samples for Basin T.
Analytical Results:
Corrective Actions: Since the Fall 2019 sampling events,housekeeping has continued in an
aggressive manner in an effort to meet benchmarks in Basin T, a Tier 2 outfall.
Basins B, E, and I:
Sample results for Basin B were within benchmark values with the exception of TSS; the result was
135mg/L, above the benchmark of 100 mg/L. Annual cleanout of the area catch basins removed high
amounts of sediment, and the result of subsequent sampling was 28 mg/L, well within the
benchmark. Cleanouts will occur semi-annually going forward. Basins E and I passed all the
benchmarks.
Basin T:
• Basin T remains a Tier 2 outfall during this semester. Rainfall allowed three representative
sampling events during the semester. The April 13, 2020 sample was within all permit
benchmarks.
• On 5/5/20, Basin T was within all benchmarks except TSS. Visual examination of the 3
sample bottles collected showed noticeable variation in solids content, so the other 2 bottles
were also tested in an effort to obtain the most representative value. The test results, 159, 85,
and 66 mg/L exhibited large variances, and averaged 103mg/L, was just above the benchmark
of 100.
S/Groups/Environmental/Stormwater/Reports/2017,18, 19 rpts/fall 2019/Anal Cyr Ltr

• The 6/10/20 sample was also within benchmarks for all parameters except TSS. Similar to
the previous sample,there was a wide visual variance in the 3 samples collected from Basin
T. As before, all 3 were tested and the results averaged. Results of 125, 166, and 50 mg/L
averaged to the reported value of 114, above the benchmark of 100mg/L. Intensive
housekeeping and maintenance of the pavement and roadsides in Basin T continues in an
effort to improve runoff quality.
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
