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. During the month of April, storm events only
occurred outside of business hours at the site. Please find enclosed a Photo Log that includes the site
Log Yard rain gauge data and April 2021 USGS Rain Gauge Data from Biltmore, North Carolina.
Due to the lack of rain, stormwater samples were not collected during April. Outfall 92 and Outfall
#5 are in Tier Two and will continue to be sampled monthly until three consecutive lab results
below benchmark. The March sampling event was the first lab result below benchmarks, two more
consecutive lab results below benchmarks are required.
If you have any questions or comment, 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.
Z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3 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, BOL, <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/C', 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 mast implement Tier 1, Tier 2, or Tier 3 responses. See General Permit text.
