Subject: Request for Additional Information
Stormwater Permit No. SW1190801
Leicester Volunteer Fire Department
Buncombe County
Dear Mr. Grieb:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on August 22, 2019. A review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
1. Please use the project name "Leicester Volunteer Fire Department" so that the application
is consistent with the plans, O&M Agreement, etc... (Section I, 1 & Section VI, 8, a).
2. As shown, the project does not qualify as low density (Section II, 2). Having a BUA
percentage less than 24% is just one aspect of having a low density project. Low density
projects must also maximize dispersed flow and utilize vegetated conveyance. Vegetated
conveyances were not utilized as the stormwater is piped around the site. A full list of the
requirements for a low density project can be found at the following link:
(htlps://files.nc. gov/ncdeq/Energy%20Mineral%20and%2OLand%20Resources/Stormwat
er/BMP%20Manual/E-1%2OLow%2ODensity%20FINAL.pdf). If you would like the
project to be a low density project, please change the design to reflect this and address the
low density comments. If you would like the project to be a high density project, please
address the high density comments.
3. Since the applicant is the property owner, Section III, 2 does not need to be filled out and
Section IX does not need to be signed.
4. If the project is low density and contains SCMs for quanti1y management only, they
should not be included in the application or submission package (Section IV, 1).

5. If the project is low density, the "Total Drainage Area" value in the "Drainage Area"
table in Section IV, 10 should be equal to the "On -Site Drainage Area" value and there
should not be any "Off -Site Drainage Area". Also, the "Total Drainage Area" value
should be equal to the entire site area.
6. If the project is high density, each SCM should have its own column in the "Drainage
Area" table in Section IV, 10 that is based on the area draining to it.
7. The "Existing BUA" row of the "Impervious Surface Area" table should only include the
existing BUA that will remain after development. The impervious areas listed in this
table should add up to the "Proposed Impervious Area" value in the "Drainage Area"
table Section IV, 10).
8. If the project is high density, supporting documents and an explanation of how the off -
site drainage area and off -site impervious areas were determined must be included
(Section IV, 11).
9. If the project is low density, the O&M form should only be included if there are swales
included in the design and a signed Supplement-EZ form should be provided showing
that the project is low density (Section V & Section VI,3).
10. If the project is high density, the O&M form should include both SCMs and a signed
Supplement-EZ form should be provided with both SCMs included (Section V & Section
VI,3).
11. We require that a copy of the application be included with the submission (Section VI, 1).
Only the original application was provided. Please provide a copy of the application.
12. Please provide a USGS map indicating the project location (Section VI, 6).
13. Please ensure all plans have a numerical and graphical scale as needed (Section VI, 8, f).
For example, sheet C300, in addition to some other sheets, does not have a scale.
14. Please dimension all BUA on the plans, similar to how the square footage for the building
is shown (Section VI, 8, j).
15. If the project is high density, please include the off -site contours so that the off -site
drainage area may be verified (Section VI, 8, k).
16. Please delineate the wetlands on the plans or provide a note stating that no wetlands exist.
Provide documentation of the qualifications and identity of the individual who made this
determination (Section VI, 8, m).
17. If the project is high density, please show the drainage areas for the SCMs on the plans
(Section VI, 8, o).

18. If the project is high density, the soils report should include the expected infiltration rate
for the area that the bioretention cell will be placed (Section VI, 9).
19. Please write the deed book and page numbers in the application (Section VI, 10).
20. Please provide official documents with name, title, and position for those listed in Section
III of the application (Section VI, 11). Please also initial this item.
21. The SCMs were not reviewed for compliance with the MDCs. If the project is high
density, ensure that the SCMs are designed in accordance with all applicable MDCs. The
MDCs can be found at the following link: (https://deq.nc.gov/about/divisions/energy-
mineral-land-resources/energ_y-mineral-land-permit-guidance/stormwater-bmp-manual)
22. If the project is high density and the rainwater storage is being used to meet State
stormwater requirements, please include it along with the other SCMs and ensure that all
relevant MDCs are adhered to.
23. Provide pdfs of all revisions, 2 hardcopies of revised plan sheets, and 1 hardcopy of other
documents. Pdfs must be uploaded using the form at:
hgps://edocs.deq.nc.gov/Forms/SW Project Submittal
Please note that this request for additional information is in response to a preliminary review.
The requested information should be received by this Office prior to October 20, 2019, or
the application will be returned as incomplete. The return of a project will necessitate
resubmittal of all required items, including the application fee. Please reference the State
assigned project number SW1190801 on all correspondence.
If you need additional time to submit the information, please submit your request for a time
extension to the Division at the contact below. The request must indicate the date by which you
expect to submit the required information. The Division is allowed 90 days from the receipt of
a completed application to issue the permit.
The construction of any impervious surfaces, other than a construction entrance under an
approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject
to enforcement action pursuant to NCGS 143-215.6A.
If you have any questions concerning this matter please feel free to contact me at
