Subject: Request for Additional Information
Stormwater Permit No. SW5200702
Snow Hill Road Pump Station
Durham County
Dear Ms. Wilson:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on July 13, 2020. A review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
The Falls Lake Nutrient Strategy requires stormwater systems to be designed to control
and treat at a minimum the runoff generated from all surfaces in the project area by one
inch of rainfall [ 15A NCAC 02B .0277(4)(e)]. The definition of runoff treatment
requires this runoff to be treated in a primary SCM [15A NCAC 02H .1002(43)]. There
is no provision in the Falls Lake Rules that allows for low density developments.
2. Please explain why the nutrient reduction portion of the review was submitted to the
Department but the TSS and peak flow requirements were submitted to the local review
program. The Falls Lake Rules include TSS and peak flow requirements.
3. Please complete the Applicant's Certification section of the SWU-101 Application Form.
4. Please submit a Supplement EZ form for the site. The Supplement EZ form is required
for all developments, including low density. The Supplement EZ form can be found on
the Stormwater Design Manual website.
5. Please submit an Operation and Maintenance Plan and Agreement. The O&M EZ form
has options for both high and low density. The O&M EZ form can be found on the
Stormwater Design Manual website.
