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. Outfall 45 remains in Tier Two and will
continue to be sampled monthly until three consecutive lab results below benchmark. Outfall #5 has
two consecutive results below benchmark and requires one more consecutive sample below
benchmarks once enough rainfall is observed and collected. Due to a miscommunication with the
lab and labels, Outfall 48 was not sampled during the first semiannual sampling event in 2021.
Outfall 48 was sampled in the month of August and is now in Tier I1 and will continue to be
sampled monthly until three consecutive lab results below benchmark. A Stormwater Inspection
was completed in response to this exceedance and a Tier Form will be filled out with the corrective
actions.
If you have any questions or comments, please contact me at [phone].
Sincerely,
Jarrett Rhinehart

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
'The 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 m L" where XX is the numerical value of the
detection limit, reporting limit, etc. in mg/L.
(Vote: Ifyou report a sample value in excess of the benchmark, you must implement Tier 1, Tier 2, or Tier 3 responses. See General Permit text.
