The proposed modification is to perform an open -cut intermittent stream crossing instead of a directional bore crossing at the Western Wake Regional Wastewater Management Facility site. The proposed open -cut stream crossing will temporarily impact 40 linear feet of stream. No mitigation is proposed for the temporary impacts to the stream. As stated in your letter the reason you are making this request is because the effluent pump station contractor's tunneling subcontractor has gone bankrupt, and a new contractor is expected to cost substantially more than what was bid and potentially delay the project significantly. After reviewing your request I have determined that 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. 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 US Army Corps of Engineers (USACE) prior to implementation. -2- If you have any questions or comments you may call Mr. Henry Wicker at (910) 251 -4930.

Re: USACE Action ID: SAW- 2005 -20159 DWQ #2006 -1203 Request for Permit Modification, Western Wake Regional Wastewater Management Facility, Wake County, North Carolina Dear Mr. Wicker: The Western Wake Regional Wastewater Management Facility (the permittee) hereby requests authorization of a modification to the permit issued for the subject project under the United States Army Corps of Engineers (USACE) Action ID SAW- 2005 - 20159. The permittee proposes a modification to the design of one stream crossing at the Western Wake Regional Wastewater Management Facility ( WWRWMF) associated with the subject permit. The permittee formally requests consideration to open -cut a stream on the WWRWMF site in order to install the 64 -inch plant effluent line and 4 -inch drain line shown on the attached Sheet G -17. The Effluent Pump Station contractor's tunneling subcontractor has gone bankrupt, and a new contractor is expected to cost substantially more than what was bid and potentially delay the project significantly. The table below and attached figures depict the impacts associated with an open -cut installation and include only the waters of the US that are proposed to be impacted by the WWRWMF site portion of the project. Impacts to jurisdictional streams that are currently permitted for the WWRWMF and associated infrastructure project include 408 feet of permanent impacts (242 feet of perennial and 166 feet of intermittent channel) and 1,878 feet of temporary impacts (984 feet of perennial and 894 feet of intermittent channel). No impacts to streams have been permitted within the WWRWMF site portion of the project. If the design modification is authorized as requested, temporary impacts to intermittent streams will increase by 40 feet. No change in the length of stream proposed to be permanently impacted will occur due to the design modification. 316 N.
