To the Division of Water Quality:
CDM Smith Inc., on behalf of Cumberland County(County), is submitting two copies of the
Stormwater Discharge Monitoring Report for Outfall 3.Samples collected from Outfall 3 during the
July to December 2014 semi-annual sampling event had a detection of chemical oxygen demand
(COD) above the benchmark value. In response to the benchmark value exceedances,the County
implemented a Tier II response.
There was no discharge from Outfall 3 in February 2016. Per the Tier II response requirements,
samples will be collected monthly for COD from Outfall 3 until three consecutive sampling events
show the parameter is below the benchmark value.The County will maintain a record of the Tier II
response and monitoring results at the landfill.
If you have any questions or require further explanation, do not hesitate to call me at(919) 325-3532.
Sincerely,

1 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.
4 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 mg/L",where XX is the numerical value of the
detection limit, reporting limit, etc. in mg/L. Conversely,where fecal coliform results exceed the dilution upper limit, report the result as">XX".
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.
