Livingston 1,2,3 TCP Removal Treatment Facility Project

Additions to the TCP Treatment Facility at Arakelian Park The scope of work for the TCP Treatment Facility at Arakelian Park remains unchanged in intent; however, this Addendum clarifies and supplements the project description provided in Addendum No. 1. Specifically, while the original description referenced the treatment facility site, it did not explicitly identify all supporting buildings, grading, and infrastructure components, including a partially buried water storage tank and booster pumps. These elements are integral to the operation of the facility and were always contemplated as part of the project’s functional design. This Addendum, Addendum No. 2 now includes these components explicitly for clarity. All previously analyzed components of the TCP Treatment Facility remain valid, and clarification of the facility and the inclusion of the storage tank and booster pumps do not result in new or more severe environmental impacts than those previously disclosed. The site layout, including the clarified components, is shown. Additions to the Well 8 site In addition to the previously approved TCP treatment facility at the Well 8 location, the City is adding two new filtration vessels and a new backwash tank (approximately 70,000 gallons) for arsenic removal to the existing Well 8 site. Relocation of Well 18 Addendum No. 1 identified the location of Well 18 on the northwest corner of White Avenue and Davis Street, with associated water pipeline running east on Davis Street, north on White Avenue, east on Swan Street and north on North Main Street to the Well 8 Centralized Treatment Site. This Addendum, Addendum No. 2, memorializes the relocation of Well 18 and the associated buildings, grading, and infrastructure components to Lucero Park, with water pipeline running west on Celia Drive and north on North Main Street to the Well 8 Centralized Treatment Site. Both the original location and the proposed relocation with associated pipeline are shown.
