Yadkin Regional Water Supply Project — 404/401 Modification Request
Dear Mr. Roden -Reynolds and Mr. Johnson,
HDR, on behalf of Union County Public Works (Union County), is requesting a modification to
the approved Clean Water Act Section 404 Nationwide Permit 12 for Utility Line Activities
(Action ID: SAW-2018-01144) and Section 401 Water Quality Certification (DWR# 20-0859) for
design changes related to the Yadkin Regional Water Supply Project,
The final erosion and sediment control (E&SC) design resulted in additional impacts to
jurisdictional surface waters not included in the approved permit authorization. In addition,
changes to the limits of disturbance to meet E&SC requirements resulted in reduced impacts to
jurisdictional surface waters previously authorized in the approved permit. Changes in impacts
will result in a net decrease of 112 linear feet of impacts to jurisdictional streams and net
decrease of 0.005 acres of impact to jurisdictional wetlands.
The following documentation is enclosed for your review and approval:
1. New spreadsheet documenting changes to the permitted impacts.
2. Revised figures documenting changes to the permitted impacts.
3. Revised impact tables documenting final proposed impacts. (Note: Separate tabs in
Excel spreadsheet for stream, wetland, and open water impacts.)
Please do not hesitate to contact me should you have questions or require additional
information to modify the existing Section 404/401 authorizations for this project.
Sincerely,
Eric M ularski, PWS
Senior Environmental Project Manager
