MEMORANDUM
To: Lyn Hardison, State Environmental Policy Act Coordinator for NC Department of Environmental Quality
From: Dave Wanucha, NC Division of Water Resources, Winston Salem Regional Offi e�.�w 4/4/2019
Subject Proposed replacement of Bridge No. 81 with a new bridge on SR 1926 over Deals Creek in Rowan
County by NCDOT. Reference your electronic correspondence dated April 1, 2019 in which you
requested comments for the project. SEPA Project No. 19-0###
NC Department of Environmental Quality, Division of Water Resources issued NCDOT a Water Quality
Certification (WQC) for replacement of Bridge 81 on March 27, 2019. The approval was based on permit
application information NCDOT submitted to our ofiice on March 11, 2019 of which is the information sent to you
by NCDOT on March 29, 2019 requesting comments. Below are DWR's comments relative to the project.
Condition(s) of Certi6cation:
Project Specific Conditions
1. 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. [15A NCAC 02H .0506(b)(2)
2. All work in or adjacent to stream waters shall be conducted per approved BMP measures from the most current
version of NCDOT Construction and Maintenance Activities manual. [] SA NCAC 02H.0506(b)(3) and (c)(3)]
3. Bridge demolition and construction must be accomplished in strict compliance with the most recent version of
NCDOT's Best Management Practices for Construction and Maintenance Activities. [15A NCAC 02H
.0507(d)(2) and 15A NCAC 02H .0506(b)(5)]
4. If concrete is used during construction, a dry work area shall be maintained to prevent direct contact between
curing concrete and stream water. Water that inadvertently contacts uncured concrete shall not be discharged to
surface waters due to the potential for elevated pH and possible aquatic life and fish kills. [1 SA NCAC
02B.0200]
5. Bridge deck drains shall not discharge directly into the stream. Stormwater shall be directed across the bridge
and pre-treated through site-appropriate means (grassed swales, pre-formed scour holes, vegetated buffers, etc.)
before entering the stream. To meet the requirements of NCDOT's NPDES permit NCS000250, please refer to
the most recent version of the North Carolina Department of Ti^ansportation Stormwater Best Manczgement
Practices Toolbox manual for approved measures. [1 SA NCAC 02H .0507(d)(2) and ] SA NCAC

General Conditions
1. The dimension, pattern and profile of the stream above and below the crossing shall not be modified.
Disturbed floodplains and streams shall be restored to natural geomorphic conditions. [15A NCAC
02H.0506(b)(2)]
2. Placement of culverts and other structures in open waters and streams, shall be placed below the elevation of
the streambed by one foot for all culverts with a diameter greater than 48 inches, and 20 percent of the culvert
diameter for culverts having a diameter less than 48 inches, to allow low flow passage of water and aquatic life.
Design and placement of culverts and other structures including temporary erosion control measures shall not
be conducted in a manner that may result in dis-equilibrium of wetlands or streambeds or banks, adjacent to or
upstream and downstream of the above structures. The applicant is required to provide evidence that the
equilibrium is being maintained if requested in writing by the NCDWR. If this condition is unable to be met
due to bedrock or other limiting features encountered during construction, please contact the NCDWR for
guidance on how to proceed and to determine whether a permit modification will be required. [15A NCAC
02H.0506(b)(2)]
3. The use of rip-rap above the Normal High Water Mark shall be minimized. Any rip-rap placed for stream
stabilization shall be placed in stream channels in such a manner that it does not impede aquatic life passage.
[isarrcac oax.oso6�b��z��
4. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval. [15A NCAC 02H .0507(c) and 15A NCAC 02H .0506 (b)(2) and (c)(2)]
5. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification. [15ANCAC 02H.0506(b)(3)]
6. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters
is prohibited. [15A NCAC 02H.0506(b)(3)]
7. The pernuttee and its authorized agents shall conduct its activities in a manner consistent with State water quality
standards (including any requirements resulting from compliance with §303(d) of the Clean Water Act) and any
other appropriate requirements of State and Federal law. If the NCDWR determines that such standards or laws
are not being met (including the failure to sustain a designated or achieved use) or that State or federal law is being
violated, or that further conditions are necessary to assure compliance, the NCDWR may reevaluate and modify
this certification. [ 15A NCAC 02B.0200]
8. All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1, unless otherwise
authorized by this certification. [15A NCAC 02H.4506(b)(2)]
9. A copy of this Water Quality Certification shall be maintained on the construction site at all times. In addition, the
Water Quality Certification and all subsequent modifications, if any, shall be maintained with the Division Engineer
and the on-site project manager. [15A NCAC 02H .0507(c) and 15A NCAC 02H .0506 (b)(2) and (c)(2)]
10. The outside buffer, wetland or water boundary located within the construction corridor approved by this
authorization shall be clearly marked by highly visible fencing or flagging prior to any land disturbing
activities. Impacts to areas within the fencing are prohibited unless otherwise authorized by this certification. [ 15A
NCAC 02H.0501 and .0502]
11. The issuance of this certification does not exempt the Permittee from complying with any and all statutes, rules,
