Dear Mr. Brown:
Please reference Hazen and Sawyer's, May 22, 2015, letter (enclosed) providing information
concerning the final activities with the Western Wake Wastewater Management Facilities
project. On July 28, 2010, the Department of the Army authorized the Western Wake Partners
(Partners) to permanently impact 0.82 acres of wetlands and 378 linear feet (If) of stream (2321f
of perennial and 1461f intermittent) in order to construct and operate new wastewater
management facilities including influent conveyance facilities, a new water reclamation facility
and new effluent conveyance facilities in western Wake County, North Carolina. The Hazen and
Sawyer's letter provided a final as -built surveys summary table and drawings of wetland and
stream impacts of:
• West Cary Pump Station
• West Cary Force Main
• West Reedy Branch Gravity Sewer
• Beaver Creek Gravity Sewer
• Beaver Creek Pump Station
• Beaver Creek Force Main
• Western Wake Water Reclamation Facility
• Effluent Pump Station
• Effluent Force Main
• Site 14 Apex Water and Sewer Extension
In total, an additional 0.1 acres of permanent jurisdictional wetlands and 8 feet fewer
permanent jurisdictional stream impacts occurred during construction of the transmission lines.
During the permit initial review process it was determined that the mitigation ratios for the
wetland and stream impacts would be 2:1. The Partners and the US Army Corps of Engineers
(USACE) agreed that 1.64 riparian credits for 0.82 acres of wetland impacts and 1,220 warm
stream credits for 6101f from the North Carolina Ecosystem Enhancement Program would
mitigate for adverse impacts to the aquatic environment for this part of the project. After making
l

final onsite reviews with Hazen Sawyer on the project and observing the placement of rock
material in jurisdictional areas for road and stream crossings it has been the determined that no
additional mitigation will be required for the 0.1 acre additional fill in these jurisdictional areas.
The original 2 to I mitigation ratio adequately compensates for adverse impacts to the aquatic
environment from this project (including the additional 0.1 acre fill).
Your proposal continues to be consistent with the provisions and conditions of your
Department of the Army permit and is hereby modified to reflect the aforementioned changes.
This letter and the enclosed Hazen and Sawyer letter and drawings should be included in your
file as a reference of these minor modifications during the construction of your project. It is
understood that all other conditions of your permit remain applicable and that the expiration date
is December 31, 2015.
Please remember that all work authorized by this permit must be performed in strict
compliance with the attached plans, which are a part of this permit. Any modification to these
plans must be approved by the USACE prior to implementation..
If you have any questions or comments you may call Mr. Henry Wicker at [phone].
