To Whorn 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. Stormwater samples were collected on
3/16/2021 from Outfalls #2, #3 and #5. All lab results were below benchmarks values. Outfall #2
and Outfall 45 are in Tier Two and will continue to be sampled monthly until three consecutive lab
results below benchmark. This sampling event is the first lab result below benchmarks.
If you have any questions or comment, please contact me at [phone].

t 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.
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.
A 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 mtt/L", where XX is the numerical value of the
detection limit, reporting limit, etc. in ml
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.
