Marti, can you send a plan or other project reference? Though I don't
believe there are any issues, Lat/Long isn't always very resolute, so I'd
like to see exactly where the project is located.
Thanks

Hey Jason,
Can you take a look at this location and see if we have any regulated units
(SWMU's or USTs) or known groundwater contamination in this location?
Thanks!

Marti,
I'm reviewing one on the NE corner of Blackjack St. and Tapline Rd.
Lat 35008' 55''N
Long 78057'44 ''W
Any issues with this area? The demo plan has no mention of O/W separators or
monitoring wells.

I have reviewed the application, received on April 26, 2011, for the subject project. There are a few items that still need
to be addressed. Please provide the following additional information:
11. Supporting calculations need to be provided for showing the minimum required treatment volume using the
Simple Method; and the infiltration trench volume provided and drawdown time.
2. The existing vs. proposed BUA is confusing as presented. Please provide a table showing existing BUA, existing
BUA to be removed, existing BUA to remain, new BUA added, and the total post -construction BUA. Also, the
table in Section IV.10 of SWU-101 appears to incorrectly show that there is zero existing BUA.
3. The narrative states the volume provided in the infiltration trench is 18,541cf, but the supplement form states it
is 17,141cf. Please make these consistent.
4. The overflow elevation is show on the plans and calculations to be 319.5. However, this elevation appears to be
incorrectly stated as 319.0 on the supplement form.
5. We typically require the infiltration rate be determined using a method like a double -ring infiltrometer or
Amoozemeter. These constant head methods yield more accurate infiltration rates.
6. Regarding Al/C-508:
a. The full plan view layout detail of the infiltration trench needs to be provided so that the contractor
knows the number of pipes, pipe lengths, and the total length and width.
b. Note 2 needs to be revised or removed. Any modification to the infiltration trench on the plans will
require approval by DWq prior to installation. Also, the note talks about providing the same required
volume in any alternative design, but does not state what that volume is on the plans.
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 June 6, 2011, or the application will be returned as incomplete.
The return of a project will necessitate resubmittal of all required items, including the application fee.
If you need additional time to submit the information, please mail, fax, or email your request for a time extension to the
Division at the address and fax number at the bottom of this letter. 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.
Please reference the State assigned project number SW6110406 on all correspondence. Only plans, forms, and/or
calculations that change need to be resubmitted. Any revised plans or calculations must be sealed, signed, and dated.
you have any questions concerning this matter please feel free to contact me at [phone], or
