Subject: COMMENTS ON DRAFT SWMP (NOV-2019-PC-0638)
Town of Woodfin
NPDES MS4 Permit No. NCS000440
Buncombe County

Dear Mayor Vehaun:

On August 28, 2019, the North Carolina Department of Environmental Quality (DEQ) audited the Town
of Woodfin (Town) for compliance with the subject NPDES MS4 permit. As a result, a Notice of
Violation (NOV) was issued to the Town on September 17, 2019. The NOV defined specific document
submittals and deadlines. DEQ received the required Draft Stormwater Management Plan (SWMP)
submittal on February 11, 2021.

Staff have reviewed the submitted Draft SWMP and have found it to be insufficient to meet the
requirements. Please consult the SWMP Template Instructions and General SWMP Guidance on
the DEQ MS4 Forms & Resources web page for additional information on preparing an
approvable SWMP and address the general comments provided below. Specific comments will be
provided once an acceptable SWMP has been submitted for review.

The revised Draft SWMP is required to be signed and submitted to DEQ within thirty (30)
calendar days of receipt of this letter.

General Comments:

1. Measurable Goals must be specific, measurable, achievable, realistic and timely BMPs to define
the specific steps to bring the program into compliance over the permit term. Many provided
measurable goals are too vague to convey the task that will be performed. Define the overall goal
of the tasks in the BMP (Column A) section to provide context for the measurable goals.
2. Include frequencies in Column C - Schedule for Implementation (Once, Annually, Continuously,
etc.) and Permit Years that the measurable goal tasks(s) will be performed.
3. Annual Reporting Metrics in Column D must be brief and should be a reportable quantity,
Y/N/Status, etc. Results, documentation, etc. are not appropriate reporting metrics, but do
identify tasks and supporting information that should be maintained on site for future compliance
audits.

Please also be aware that the SWMP will directly translate into an excel spreadsheet for the
annual assessment (annual report) that will be required once a new permit is issued. Therefore,
reporting metrics should be brief and additional documents will not be acceptable. This is to
facilitate electronic annual reporting in the future. These annual assessments will be utilized to
ensure the MS4 is on track to compliance. However, supporting documentation should be
maintained on site for the next compliance audit.

The required revised Draft SWMP v2 submittal must a hard copy with a certifying statement and original
“wet” signature by the Town’s ranking elected official or designated staff member in compliance with
Part IV, Paragraph G of the current MS4 Permit.

Please submit the required signed Draft SWMP v2 to:
