The property is designated by West Orange as Block 155, Lot 26.01 in the City of West Orange, New Jersey which encompasses a total of 23.57 acres (refer to Figure 1-1 for the project’s general vicinity map). The site is located at the corner of Prospect Avenue and Mt Pleasant Avenue. One access point to the station will be reconstructed at the south side of the station from Mt Pleasant Avenue. The expansion of the switching station, including the fence replacement, utility connections, and driveway updates, has an overall project disturbance of approximately 3.92 acres. The site is an existing PSE&G switching station with several concrete foundations, pieces of electrical equipment, significant amounts of below-ground duct banks, a multistory brick building at the western edge of the site and a guard house located near the existing access drive. Immediately adjacent to the proposed site, to the west is a large shed, and to the north is a small parking lot and additional electrical infrastructure. The proposed station yard is to be made up of standard station gravel, various equipment foundations and new Ameristar security fence which shall replace the existing decorative fence. 1.2 Project Description Below is a list of major equipment and site improvements to be installed as part of the project: New 1 – 26kV metal enclosed switchgear ring bus with 28 feeder positions 2 – 26kV capacitor banks 3 – 26kV transformer breakers 1 – 26kV transformer neural ground resistor with fast acting ground witch perimeter fence Demolition of existing 26kV breakers, disconnects, and feeder positions 1.3 Project Stormwater Management Requirements Per N.J.A.C. 7:8, a Major Development is defined as: 1.
