DENR - WATER QUALITY
WETLANDS AND STORImATER BRANCH
On behalf of the Town of Swansboro, we offer the following responses to comments
received from your office on April 4, 2004:
Comment No. l: According to Mr. Ken Pohlig of DWQ's Construction Grants and
Loans Section, the Town will be required to grade and install a
liner in the footprint of the storage lagoon. Therefore this activity
will result in a discharge of fill material to the isolated wetlands
PAYMENT within the footprint of the lagoon and an isolated wetland permit
will be required for this fill. Since the total impact for the lagoon
RECEIVED exceeds one acre, compensatory mitigation at a 2:1 ratio will be
required in this permit. Please provide a mitigation plan that meets
the requirements of 15A NCAC 2H.1305(g). In addition, DWQ
will need to prepare a Public Notice for this project once the
mitigation and monitoring plans (see below) are prepared.
Response No. 1: The appropriate ?vellands permits have been filed with NCDENR-
DIVQ and the USACOE. The Town of Swansboro intends to bury
into the Ecosystem Enhancement Prot-ram (EEP) ill lien of
providing a mitigation plait. A request allowing the Town of
Swansboro to bity into the EEP has been made by the Toivut.

Comment No. 2: As discussed with Mr. Green, discharge of treated wastewater into
a portion of the remaining isolated wetlands on the site is exempt
from the isolated wetland rules. However as discussed, we may
recommend that monitoring be included in DWQ's non-discharge
permit for these areas in order to be sure that wetland impacts are
minimal. I believe that a site visit will be needed to determine the
need for monitoring and am in the process of scheduling a site visit
with Kim Colson (Non-Discharge Unit), Ken Pohlig (Construction
Grants and Loans Section), Ed Schwartzman of the Wetlands Unit
and Noelle Lutheran (DWQ's Wilmington Regional Office) as
well as yourself. Once we have a tentative date for the meeting, I
will call you to confirm.
Response No. 2: A visit to the site has been made to view the subject isolated
wetlands and there will be some minor irrigation discharges into
isolated wetlands as the rule allows.
Comment No. 3: According to Mr. Colson, the location of spray fields near wetlands
may require additional setbacks or a variance from the setback
rules. Please call Mr. Colson at 919-733-5083, ext. 540 to clarify
and discuss this issue.
Response No. 3: In accordance with NC Administrative Code Section ISA NCAC
02H 0.0219 (k)(1)(c)6)(IV) the following have been maintained:
100 foot buffer from edge of spray influence to surface
ivaters classified SA.
23 foot buffer from edge of spray influence and non-SA
classified waters and wetlands.
Also, in accordance with NC Administrative Code Section I5A
NCAC 02H 0.1301(e)(3) the following is exempt from the rule:
Discharges of treated effluent into isolated wetlands and isolated
classified surface waters resulting front activities which receive
NI-IDES Permits.
Please find enclosed check in the amount of $275.00 to cover the additional
application/processing fees.
