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.
