The project shall be constructed in accordance with your application dated received May 3, 2019. After reviewing
your application, we have decided that these impacts are covered by General Water Quality Certification Number
4132 and 4133. These certifications correspond to the Nationwide Permits 3 and 12 respectively issued by the
Corps of Engineers. This approval is also valid for the Neuse Riparian Buffer Rules (15A NCAC 213.0233). In
addition, you should acquire any other federal, state or local permits before you proceed with your project including
(but not limited to) Sediment and Erosion Control, Non -Discharge and Water Supply Watershed regulations. This
approval will expire with the accompanying 404 permit.
This approval is valid solely for the purpose and design described in your application (unless modified below).
Should your project change, you must notify the NCDWR and submit a new application. If the property is sold, the
new owner must be given a copy of this Certification and approval letter,and is thereby responsible for complying
with all the conditions. If total wetland fills for this project (now or in the future) exceed one acre, or of total
impacts to streams (now or in the future) exceed 300 linear feet, compensatory mitigation may be required as
described in 15A NCAC 2H .0506 (h) (6) and (7). Additional buffer impacts may require compensatory mitigation
as described in 15A NCAC 213.0233.. For this approval to remain valid, you must adhere to the conditions listed in
the attached certification(s) and any additional conditions listed below.

19. Pursuant to 15A NCAC 2B.0233(6), sediment and erosion control devices shall not be placed in Zone 1 of any
Neuse Buffer without prior approval by the NCDWR. At this time, the NCDWR has approved no sediment
and erosion control devices in Zone 1, outside of the approved project impacts, anywhere on this
project. Moreover, sediment and erosion control devices shall be allowed in Zone 2 of the buffers provided
that Zone 1 is not compromised and that discharge is released as diffuse flow.
20. The post -construction removal of any temporary bridge structures must return the project site to its
preconstruction contours and elevations. The impacted areas shall be revegetated with appropriate native
species including woody species. [15A NCAC 02H.0506(b)(2)
21. Due to the possibility that compaction and/or other site alterations might prevent the temporary wetland impact
area from re -attaining jurisdictional wetland status; the permittee shall provide an update on the wetland areas
temporarily impacted by the temporary detour bridge. This update shall be conducted two growing seasons
after completion of the work and shall consist of photographs and a brief report on the progress of the areas in
re -attaining wetland jurisdictional status. Upon submission of this update to the NCDWR, the permittee shall
schedule an agency field meeting with the NCDWR to determine if the wetland areas temporarily impacted by
this project have re -attained jurisdictional wetland status. If the wetland areas temporarily impacted by this
project have not re -attained jurisdictional wetland status, the NCDWR shall determine if compensatory
wetland mitigation is to be required. [I 5A NCAC 02H.0506(b)(2) and (b)(3)]
