RE: Stormwater Discharge Outfall Monitoring Report
Columbia Forest Products, Old Fort, North Carolina
COC No.: NCG210136
To Whom It May Concern:
Please find attached the Stormwater Discharge Outfall Monitoring Reports for Columbia Forest
Products located in Old Fort, North Carolina (Columbia Carolina). Columbia Carolina operates
under Certificate of Coverage Number NCG210136. Samples were taken on 10/5/2021 which
completes the semiannual sampling for Outfall 41, #2, #3 and 45. There was no discharge at Outfall
#8, see photo 1 in photo log. All samples were below benchmarks. Outfall #8 remains in Tier Two
and will continue to be sampled monthly until three consecutive lab results below benchmark.
Outfall #8 was monitored for the remainder of the month for a discharge to sample however no
discharge was noted.
If you have any questions or comments, please contact me at [phone]
Sincerely,
Jarrett Rhinchart

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance forthe same parameter at the same outfall.
Z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
See General Permit text, Table 3, identifying the especially sensitive receiving water classifications where the more protective benchmark applies,
Note: Results must be reported in numerical format. For example, do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -
numerical format. When results are below the applicable limits, they must be reported in the format, "<XX me/L" where XX is the numerical value of the
detection limit, reporting limit, etc. in mg/L.
Note: If you report a sample value in excess of the benchmark, you must implement Tier 1, Tier 2, or Tier 3 responses. See Genera! Permit text.
