You can use a new date/seal on the plans and we only need the updated plan sheets. If you want, you can send 2x hard
copies of a revised cover page listing this revision on it for clarity, but it is not necessary (we stamp each plan sheet as
being approved).

Just realized will have to update the entire hydrocad model and that’s most of the calc book so ill just send a new one!
As for the plans, should we seal these with same date as last submittal or can we add a new seal date to changed sheets.
Didn’t know if you wanted it consistent. We can also update all sheets with new date and re-send if you like.
Thanks.

Jim,
Assuming you want me to send hardcopies and digital again?
For the plans, would you like for me just to send sheets C03 and C12 (the ones that changed or would you like a new
planset).
For calcs. Really only two pages in calc book are changing but would you just like a whole new hard copy calc book.
Thanks.

Subject: RE: Denver Defense; 1417 NC-16 Business, Denver, Lincoln County
Jay,
I was looking over the information you provided on March 3, 2022. Everything looks good except for a few small issues
(It looks like a lot of comments, but they are fairly minor, I was just trying to be thorough):
Please correct the following:
- General MDC 4 – Please provide calculations showing that the outlet of the SCM (existing outfall to remain) will
be stable during the 10-year design storm.
- Off-site component of the drainage area to the Sand Filter – Per 15A NCAC 02H .1003(3)(b), any off-site areas
that are not bypassed around the SCM are required to be accounted for at their full build-out capacity. Since the
off-site portions of the drainage area are not owned by the permittee, the full build out potential of the off-site
area must either be limited by a legal agreement between the property owners (limiting the amount of BUA and
drainage area that the off-site property owner can direct toward the permittee’s SCM) or by assuming that the
off-site area is 100% BUA (it’s full build-out potential). It is recommended to bypass these off-site areas around
SCMs (as to avoid having to deal with stormwater runoff that the permittee has no control over), but since this is
such a small amount of off-site drainage area, it might be easier to just account for it at 100% BUA (The SCM
size/design should not need to be modified to account for this extra area).
- Application, Section IV, 10:
o On-site Drainage Area – Per the information provided in other parts of the submission, the on-site
portion of the drainage area to the SCM is 117,333 sf.
o Off-site Drainage Area – Per the information provided in other parts of the submission, the off-site
portion of the drainage area to the SCM is 2,269 sf.
o % Impervious Area – The percent impervious area for the drainage area to the SCM would be calculated
as the total BUA within the drainage area divided by the total drainage area.
o On-site Buildings/Lots – This item is equal to the amount of new BUA added within the drainage area to
the SCM that corresponds to a building or roof area. It should match the “Roof” item under Line 12 of
the Drainage Area 1 Column on the Drainage Areas Page of the Supplement-EZ Form.
4
o On-site Parking – This item is equal to the amount of new BUA added within the drainage area to the
SCM that corresponds to parking area. It should match the “Parking” item under Line 12 of the Drainage
Area 1 Column on the Drainage Areas Page of the Supplement-EZ Form.
o On-site Sidewalks – This item is equal to the amount of new BUA added within the drainage area to the
SCM that corresponds to sidewalk area. It should match the “Sidewalk” item under Line 12 of the
Drainage Area 1 Column on the Drainage Areas Page of the Supplement-EZ Form.
o Other On-site – This item is equal to the amount of new BUA added within the drainage area to the SCM
that does not correspond to one of the other listed BUA types. It should match the “Other” item under
Line 12 of the Drainage Area 1 Column on the Drainage Areas Page of the Supplement-EZ Form.
o Future – This item is equal to the amount of new BUA that will be added at some future time within the
drainage area to the SCM. It should match the “Future” item under Line 12 of the Drainage Area 1
Column on the Drainage Areas Page of the Supplement-EZ Form.
o Off-site – This item is equal to the amount of BUA that is located within the off-site portion of the
drainage area to the SCM. It should match the “Offsite BUA” listed on Line 11 of the Drainage Area 1
Column on the Drainage Areas Page of the Supplement-EZ Form.
o Existing BUA – This item is equal to the amount of existing BUA that will remain within the drainage area
to the SCM. It should match the “Existing BUA that will Remain” listed on Line 15 of the Drainage Area 1
Column on the Drainage Areas Page of the Supplement-EZ Form.
o Total - This item is equal to the total amount of BUA that will exist within the drainage area to the SCM
once all construction is complete (final condition). It should match the “Total BUA” listed on Line 8 of
the Drainage Area 1 Column on the Drainage Areas Page of the Supplement-EZ Form.
- Supplement-EZ Form:
o Cover Page:
Line 7 – Please include the required vegetated setback width from on-site surface waters as
required per 15A NCAC 02H .1017(10). It is noted that there are no surface waters located on-
site, however, this value should still be reported.
o Drainage Areas Page:
General:
Line 16 – Since this site does not have an existing post-construction stormwater permit,
there should not be any “already permitted” BUA listed (The total amount of existing
BUA can be inferred by adding together Lines 15 & 17).
Entire Site Column:
Lines 5 & 6 – For a project like this the “drainage area” for the entire site is equal to the
project area. As such, these values would be 195,759 sf.
Line 7 – Similar to the above comment, for a project like this, there is no off-site
component to the “drainage area” (project area).
Drainage Area 1 Column:
Please see the earlier comments for a description of the items of Lines 8, 11, 12, & 15
Line 10 – This item is the sum of all of the BUA listed under Line 12 for the Drainage
Area 1 Column.
Line 17 – This item is the amount of existing BUA that will be removed from the
drainage area to the SCM.
NOTE: You may wish to make a table similar to the one provided on plan sheet EX01,
but instead of the entire site, the bounding area would be the (this is not required). If
you are having trouble with theses BUA tables, let me know, I can help you out some.
o Sand Filter Page:
Line 3 – This item askes if the SCM is sized to treat all surfaces draining to it at build-out
(corresponds to General MDC 1). It appears as though this SCM is adequately sized for its
drainage area.
Line 18 – Please update this item per the provided SHWT report.
Lines 23 & 30 – These items should show the volume that can be stored in the sediment
chamber and sand chamber respectively at the temporary pool elevation (843.5’). The sum of
5
these items should be equal to the value shown on the stage-storage table at this elevation and
the volumes of the sediment chamber and sand chamber should be approximately the same
(Sand Filter MDC 2).
Line 25 – Please indicate this value on the plans.
Lines 27 & 28 – For this configuration, the depth of the sediment chamber is the distance from
the temporary pool elevation (843.5’) to the bottom of the sediment chamber (Line 25).
Line 29 – The plans indicate that this value 843.5. Please revise either as needed.
Lines 33 & 34 – For this configuration, the depth of the sand chamber is the distance from the
temporary pool elevation (843.5’) to the top of the sand layer (bottom of the sand chamber)
(Line 31).
Line 35 – Per the plans, the lowest bypass elevation for the sand filter is the 6” orifice with an
invert of 843.5. Please revise.
Line 36 – As noted above, the lowest bypass device is an orifice.
Line 39 – This item refers to the depth of the sand layer (not the entire sand and gravel layer)
above the underdrain. Per the plans, this value is 18”.
- NOTE: You are only required to treat the net increase in BUA for this project. If you like, you can cache the
17,360 sf of overtreated BUA (53,453 sf required to be treated, 70,813 sf actually treated) as “future” BUA that
can be used for future improvements to the site. If you are doing this, please indicate the amount of future BUA
in Section IV, 10 of the Application and the Supplement-EZ Form. NOTE: if the off-site portion of the drainage
area is assumed to be 100% BUA, it does not count toward the overtreated BUA amount.
Please provide the following:
- 1x hard copy & 1x electronic copy of the revised page of the Application.
- 1x hard copy & 1x electronic copy of the revised pages of the Supplement-EZ Form.
- 1x hard copy & 1x electronic copy of the revised calculations (as needed).
- 1x hard copy (2x hard copies for plan sheets) & 1x electronic copy of anything else needed to address these
comments.
Hard copies should be mailed to me at the following address:

Hand Delivery:
Please reach out to me prior to hand delivering a submission to make sure that I (or someone else in my group)
will be able to receive the submission. Do not leave the package in the foyer with the security guard.
NOTE: Hard copies should not be sent to a Regional Office. Doing so will delay the review process and the
submission package may be lost while being sent from the Regional Office to me in the Central Office.
Electronic copies should be uploaded at the following location:

Good Morning,
8
We received your application for a new post-construction stormwater permit on 2/17/2022. At this time, the submission
is not administratively complete and cannot be accepted for review in its current condition. Please provide the following
submittal items within 30 calendar days (by close of business on 3/21/2022) so that we may accept the project and
begin the review process, otherwise, the project will be returned as administratively incomplete.
- 1x complete hard copy of the Supplement-EZ Form. This item is required per Section V & VI, 3 of the Application.
NOTE: This form uses macros to generate the correct pages, depending on what is entered into the cover page.
The complete form should have a cover page, drainage areas page, and a sand filter page (only the cover page
was provided).
- 1x complete O&M Agreement Form. This item is required per Section V & VI,3 of the Application and 15A NCAC
02H .1042(2)(j). Similar to the Supplement-EZ Form, this form uses macros to generate the correct pages
(describing the maintenance requirements that the Applicant is agreeing to perform). NOTE: You may wish to
get a second version of this form notarized for the Applicant to keep (since the Register of Deeds will require an
original for recording).
- 1x complete hard copy of the signed & notarized Application. Section X (Applicant’s Certification) of the
Application must be signed and notarized by the Applicant. Per 15A NCAC 02H .1040(1), if the Applicant is an
LLC, the signing official (listed in Section III, 1a and signed Section X of the Application) must be by a manager or
company official (Ben Wilson is not listed on the Secretary of State’s website
(https://www.sosnc.gov/online_services/search/by_title/_Business_Registration) as a manager or company
official for PSA Denver, LLC). Please do one of the following: 1) Have Julian Wilson listed as the Applicant
(Section III, 1a) and sign the Applicant’s Certification (Section X) since he is listed with the Secretary of State as a
manager for PSA Denver, LLC or 2) provide official documentation from an acceptable individual (such as Julian
Wilson) stating that Ben Wilson has signatory authority for PSA Denver, LLC and have Ben Wilson sign the
Applicant’s Certification (Section X). Since the Applicant is also the Property Owner, Section IX of the Application
should not be signed.
- It is noted that the SHWT elevation information was not provided, but will be provided at a later date (per the
Application). Please be aware that the permit will not be able to be issued until this information is received and
reviewed.
- 2x signed & sealed hard copies of a plan sheet showing the following:
o Delineated drainage areas to the proposed sand filter (Required per Section IV, 8o of the Application
and 15A NCAC 02H .1042(2)(g)(iv)). It is noted that one full sized copy of the drainage area map was
provided as part of the calculations, however, we require this to be provided in the main plan set (You
can just provide an additional hard copy and I will slip-sheet them into the plan sets).
o Wetland delineation or a note on the plans stating that there are no wetlands located on-site (Required
per Section VI, 8m of the Application and 15A NCAC 02H .1042(2)(g)(iii)). Please also list the name of the
individual that made this determination in a note on the plans.
NOTE: This is an administrative completeness review, not a detailed engineering review, there may be other issues that
may be brough up during the engineering review):
- While not required to be addressed for administrative completeness…
o it appears as though the old design standards may have been used to design the proposed sand filter
(the sand filter calculation page references Chapter 11 of the BMP Manual which was revised in 2017
due to a rule change). The current design standards can be found at the following link:
https://deq.nc.gov/about/divisions/energy-mineral-and-land-resources/stormwater/stormwater-
program/stormwater-design Please ensure that the latest design requirements are met.
o there does not appear to be a stormwater maintenance/access easement around and leading to the
proposed sand filter (required per General MDC 8 & 9).
o per the guidance in Part C-6 of the Manual, the surface of the filter of the sand filter should be covered
in sand, not sod (bottom of page 6). NOTE: This is not a requirement, but a recommendation (It helps
with maintenance and helps prevent clogging of the sand filter).
9
If these items are received within the stipulated timeframe, we can accept the project and begin the review process.
Once accepted, reviews under the standard permitting process generally take 30 – 45 calendar days, but can take up to
90 calendar days per statute (one of our two reviewer positions is currently vacant so this review will probably be closer
to 45 days than 30).
