This document is a NEPA Environmental Checklist (EC) for the "B562 Replace MAU#1" project at NAVSUBASE NEW LONDON CT. It details the environmental requirements associated with the proposed project, which involves the Design-Build replacement of two existing Makeup Air Units (MAU) in the B562 Hazardous Waste Management Facility. The new units will be energy-efficient and may incorporate technological innovation. The scope includes installation of new MAUs, associated utilities, controls, and removal of existing units and associated components. A key consideration is the potential presence of PFAS in the area where an existing concrete pad will be removed.

This checklist highlights environmental considerations and requirements that may impact the project's timeline, cost, and execution. Bidders should note the following:

• Project Timeline: NEPA completion is required before award. Other environmental reviews (e.g., Coastal Zone Management, Cultural Resources, Air Emissions) may take several months.
• Scope of Work: Includes installation of new MAUs, utilities, controls, and removal of existing equipment and a concrete pad. Potential for encountering PFAS and managing contaminated soil/groundwater.
• Environmental Requirements: Compliance with Federal, State, and local environmental regulations is mandatory. Specific requirements include waste management, refrigerant handling, stormwater management, and potential coordination with environmental agencies.
• Site Conditions: Potential PFAS contamination in the work area and the need to manage excavated soil and groundwater.

This document is a research report from the Office of Legislative Research titled "SALES TAX EXEMPTION FOR BUILDING MATERIALS USED IN STATE CONSTRUCTION PROJECTS." It explains Connecticut's state sales and use tax exemption for building materials purchased by contractors for use in construction projects for state agencies and other exempt entities. It details the scope of the exemption, which applies to materials permanently installed or placed in a project, but not to equipment or tools. The report also outlines the process for contractors to obtain this exemption using a DRS certificate (CERT-141) and the penalties for misuse.

This document is relevant to bidders on state construction projects as it clarifies tax obligations related to materials. Understanding this exemption can impact a bidder's cost proposals and operational planning. The report also provides context by comparing Connecticut's exemption to those in 15 other states, which may be relevant for contractors operating in multiple jurisdictions or for understanding the broader landscape of state construction tax laws.
