Inspection Date: 05/19/2008 Inspection Type: Staff Report Reason for Visit: Routine
Inspection Summary:
ARO believes that this project should be issued with the following conditions
All Progress Energy sourced ash fill shall be encapsulated in a liner which complies with the issued Non-Discharge requirements
(permeability of 1 `10 -7)
All setbacks in the non-discharge requirements shall be adheared to. (ie no waste ash fill over waters)
All stormwater generated on the airport property shall be collected and treated such that surface water standards are not
contriveined. BMP's, as detailed in your application shall be in place no later than 30 days of receipt of this authorization.
Compensatory Mitigation Using the Ecosystem Enhancement Program (EEP)
Mitigation must be provided for the proposed impacts as specified in the table below. We understand that you wish to make a
payment to the Wetlands 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. Until the EEP
receives and clears your check (made payable to: DENR - Ecosystem Enhancement Program Office), no impacts specified in this
Authorization Certificate shall occur. The EEP should be contacted at [phone] if you have any questions concerning payment
into a restoration fund. You have one month from the date of this approval to make this payment. For accounting purposes, this
Authorization Certificate authorizes payment into the Wetlands Restoration Fund to meet the following compensatory mitigation
requirement:
Compensatory Mitigation Required
Stream 2770 (feet)
Wetlands 1 0 (acres)
Turbidity Standard
The turbidity standard of 50 NTUs (Nephelometric Turbidity Units) shall not be exceeded as described in 15 A NCAC 2B..0200
Appropriate sediment and erosion control practices must be used to meet this standard.
No Impacts Beyond those in Application
No waste, spoil, solids. or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the impacts depicted
in the Pre-construction Notification. All construction activities, including the design, installation, operation, and maintenance of
sediment and erosion control Best Management Practices, shall be performed so that no violations of state water quality standards,
statutes, or rules occur.
Construction Stormwater Permit NCGO10000
Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land Resources (DLR) or a DLR delegated
local erosion and sedimentation control program, an NPDES General stormwater permit (NCG010000) administered by DWQ is
automatically issued to the project. This General Permit allows stormwater to be discharged during land disturbing construction
activities as stipulated by conditions in the permit. If your project is covered by this permit [applicable to construction projects that
disturb one (1) or more acres], full compliance with permit conditions including the sedimentation control plan, self-monitoring, record
keeping and reporting requirements are required. A copy of this permit and monitoring report forms may be found at
http //h2o.enr.state nc.us/su/Forms_Documents htm.
