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. There was no discharge at Outfall #8 during
the month of July 2022. See photo 1 in the June Photo Log for Log Yard Rain Gauge Log and photo
2 in the photo log for a view of Outfall #8. Improvements made to the drainage ditch to Outfall #8
have increased detention time of stormwater to Outfall #8 and thus, there was no discharge from
Outfall #8 for the month. Outfall #8 remains in Tier Two and will continue to be sampled monthly
until three consecutive lab results are below benchmarks.
If you have any questions or comments, please contact me at [phone].
Sincerely,
Nason Banner

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the 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 maybe 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.
Note: If you report a sample value in excess of the benchmark, you must implement Tier 1, Tier 2, or Tier 3 responses. See General Permit text.
