The proposed work consists of installing a 14.5 mile, 16 inch gas main by trench and backfill, widening portions of the Right of Way (ROW) easement by 10 feet, and the installation of a permanent roadway crossing of a tributary with a culvert to retain hydrological flow.  In detail, the gas main will pass through twenty-seven (27) jurisdictional wetlands and two (2x) tributaries.  The project seeks to temporarily impact 7.083 acres of wetlands with temporary clearing impacts for site preparation, 8.908 acres of wetlands with temporary excavation and backfill impacts for the installation of the gas main, 0.004 acres of tributaries with permanent fill impacts for the creation of a roadway crossing with associated culvert, and 2.519 acres of wetlands with permanent clearing and conversion of land from forested wetlands to emergent wetlands. The applicant has proposed to mitigate for impacts to wetlands and/or waters of the United States by purchasing 12.7 mitigation credits from a third party mitigation bank. As stated by the applicant the following avoidance and minimization practices will be utilized: “The negligible amount of fill impacts (0.004 acres) associated with the project prevents smothering of organisms and disruption of periodic water inundation patterns.  Most of the proposed impacts will be temporary.  Stormwater best management practices will be implemented during construction activities to minimize sedimentation and confine suspended particulate/turbidity to a small area where settling or removal can occur.  Mats will be used as applicable to prevent rutting associated with mechanized clearing.  The applicant will employ appropriate maintenance and operation on equipment or machinery, including adequate training, staffing, and working procedures.  The applicant will use machinery and techniques that are especially designed to reduce damage to wetlands. This may include machines with specially designed wheels or tracks, and the use of mats under heavy machines to reduce wetland surface compaction and rutting. The applicant has designed access roads and channel spanning structures using culverts, open channels, and diversions that will pass both low and high-water flows, accommodate fluctuating water levels, and maintain circulation and faunal movement where applicable.  The project will avoid sites having unique habitat or other value, including habitat of threatened or endangered species.” As stated by the applicant, the project purpose is “to support the development of a gas main installation referred to as River Neck to Kingsburg 16” Gas Main.”
