SUPPLEMENTARY INFORMATION:

Background: CDC is dedicated to protecting health and promoting quality of life through the prevention and control of disease, injury, and disability. NIOSH was established by the Occupational Safety and Health Act of 1970. NIOSH plans, directs, and coordinates a national program to develop and establish recommended occupational safety and health standards, conduct research and training, provide technical assistance, and perform related activities to ensure safe and healthful working conditions for every working person in the United States.

In 1997, when the mine safety and health function was transferred from the Bureau of Mines (BOM) to NIOSH, NIOSH took over the lease for a facility referred to as the Lake Lynn Experimental Mine (LLEM). The BOM had leased the LLEM facility since 1982. The LLEM is located 60 miles south of Pittsburgh, Pennsylvania. The LLEM and its aboveground fire testing facility were primarily used for studies and research on mine explosions, mine seals, mine rescue, ventilation, diesel exhaust, new health and safety technologies, ground control, and fire suppression. After December 2012, the property was no longer available for long-term leasing. CDC attempted to purchase the underlying property on which LLEM is located, but NIOSH vacated the LLEM after market-based ( printed page 59392) purchase offers were rejected by the property owners.

In 2013, CDC completed a Project Development Study to outline a design solution to replace the LLEM. The study presented the facility and site requirements and design concepts for the replacement facilities. In 2016, to identify potentially available locations that could accommodate the space requirements defined in the 2013 study, GSA issued (on behalf of CDC) two separate Requests for Expressions of Interest (REOI) for a site, developed or undeveloped, that could be used for the new underground safety research facility. The first REOI, advertised in June 2016, contained a limited delineated area within a 200-mile radius of the LLEM. The REOI set forth criteria that would be used to evaluate the suitability of the submitted sites. One expression of interest that had the potential to meet the minimum criteria was received. After further evaluation, however, the site was found to be non-viable.

The second REOI was issued in October 2016 and expanded the delineated area to the entire contiguous United States. Three expressions of interest were received for sites in Kentucky, Missouri, and West Virginia. The Kentucky site did not meet the minimum criteria, and the Missouri site expression of interest did not contain all necessary information to evaluate. The offeror of the Missouri site did not respond to subsequent GSA inquiries.

The potential Site in West Virginia met the minimum criteria and was determined to be a viable site. The Site is located near Mace, West Virginia, and straddles the Randolph and Pocahontas County lines.

Under the National Environmental Policy Act (NEPA), as implemented by the Council on Environmental Quality (CEQ) Regulations (40 CFR parts 1500-1508), Federal agencies are required to evaluate the environmental effects of their proposed actions and a range of reasonable alternatives to the proposed action before making a decision. In compliance with NEPA, CDC published a Draft Environmental Impact Statement (EIS) for the acquisition of the Site and construction of a new underground safety research facility on February 14, 2019 and a Final EIS on July 16, 2021. The Draft EIS was available for public review and comment for 51 days. All comments received were considered when preparing the Final EIS. The Draft and Final EIS analyzed two alternatives: The Proposed Action Alternative (acquisition of the Site and construction of a new underground safety research facility) and the No Action Alternative. The Final EIS identified the Proposed Action Alternative as CDC's Preferred Alternative.

After carefully considering the Final EIS and all comments received, CDC has made the decision to implement the Proposed Action Alternative. CDC's rationale for this decision is detailed in the ROD. The ROD incorporates all the mitigation and minimization measures described in the Final EIS.
