2. Buffer Mitigation (EEP)
You are required to mitigate for impacts to the protected riparian buffers. The required
area of mitigation to compensate for 375 square feet of impacts to Zone 2 of the protected
riparian buffers is 563 square feet as required under this variance authorization and 15A
NCAC 2B .0233. We understand that you wish to make a payment into the Riparian
Buffer Restoration Fund administered by the NC Ecosystem Enhancement Program
(EEP) to meet this mitigation requirement. This has been determined by the DWQ to be
a suitable method to meet the mitigation requirement. In accordance with 1 SA NCAC 2B
.0233, this contribution will satisfy our compensatory mitigation requirements under 15A
NCAC 2B .0233(9)(C). Until the EEP receives and clears your check (made payable to:
DENR -Ecosystem Enhancement Program Office), no impacts specified in this variance
authorization shall occur. Ms. Susan Klimek should be contacted at [phone] if
you have any questions concerning payment into the EEP. For accounting purposes,
this variance authorization authorizes payment into the Riparian Buffer
Restoration Fund to compensate for 563 ftZ of required riparian buffer mitigation
for impacts to 375 ft2 of protected riparian buffers; 03020201 river and subbasin."
