To the Division of Water Resources:
CDM Smith Inc., on behalf of Dare County (County), is submitting one copy of the Stormwater Discharge
Monitoring Report for Outfall 2. A copy of the discharge monitoring report has been uploaded to the
eDMR system. Samples from Outfall 2 collected during the April 2021 semi-annual sampling event
exceeded the benchmark values for chemical oxygen demand (COD) and pH for the second consecutive
monitoring period. In response to the consecutive benchmark value exceeclances, the County
implemented Tier I and 2 responses.
No measurable storm events occurred during normal operating hours in November. Per the Tier 2
response requirements, samples will be collected monthly from Outfall 2 for all parameters until three
consecutive sampling events show the parameters are below the benchmark values or reprieve from
sampling is granted as requested in the quarterly report for July I — September 30, 2021. The County will
continue to maintain a record of the Tier I and 2 responses and monitoring results at the landfill.
If you have any questions or require further explanation, do not hesitate to call me at [phone].
Sincerely,
��' V/1
