Size 540 acres Area to be Reused About 243 acres Ownership Puerto Rico Industrial Development Company Current Site Uses • Baxter Healthcare, a medical equipment and supplies manufacturing company • Haleon, a medical equipment and supplies manufacturing company • A groundwater treatment system and a network of monitoring wells Use Restrictions • The Puerto Rico Department of Natural and Environmental Resources requires a permit to install groundwater wells. Surrounding Population 4,929 1 MILE 23,553 3 MILES 40,277 5 MILES Site H story and Redevelopment Timeline 1966-1980 • The Puerto Rico Aqueduct and Sewer Authority installed and operated five water supply wells in the area. • Fibers International Company started making nylon fibers at the site. Chevron Chemical Company later leased the property and began making polypropylene fibers on-site. Wastewater went into settling lagoons before being treated on-site and discharged to the sea. 1982 • The U.S. Geological Survey found contamination in groundwater during a survey of public water supply wells. Pumping at these wells was stopped after the discovery of contamination. 1983 • On-site investigations found high levels of organic and inorganic contamination in site soil and groundwater. November 2024 1984 • The EPA added the site to the Superfund National Priorities List. 1984-1985 • A pharmaceutical plant opened on-site. Changes to site infrastructure included digging up parts of the settling lagoons and making the stormwater retention pond bigger. 1991 • The EPA selected a plan for the site to include pumping and treating contaminated groundwater, and excavating and disposing contaminated soil off-site. 2000 • Remedy construction finished. 2019 • Solar developers, Clean Flexible Energy, LLC, reached out to the EPA to express interest in developing a solar project at the site. EPA regional staff sent a comfort letter to the developers. 2024 • Clean Flexible Energy, LLC began working on designs and preparing documents for permits to install and operate an 80-megawatt solar generation and 110-megawatt storage facility at the site and on contiguous land. • Soiar project mobilization activities started in September 2024. 2025 • Soiar project operations are expected to start by the end of 2025. Groundwater treatment is ongoing. ------- History and Cleanup The site includes a vacant, undeveloped former sugar cane field and an area that hosted a synthetic fibers manufacturing plant. Its operations contaminated soil with asbestos-containing materials and groundwater with volatile organic compounds that impacted public water supply wells. The manufacturing plant and adjacent lots were later developed for pharmaceutical manufacturing. In 1984, the EPA added the site to the Superfund National Priorities List. The cleanup for the site included pumping and treating contaminated groundwater, removing asbestos containing materials, and digging up contaminated soil for disposal off-site. The site's potentially responsible parties completed removing asbestos-containing materials and contaminated soils by 1994. In total, they removed 7,950 tons of asbestos-containing material, which went to an authorized landfili. Groundwater treatment is ongoing. O'o *o- 7,950 tons of asbestos-containing material was taken off- site for proper disposal. 4 3.57B gallons of water have been treated at the site to date. Groundwater treatment is ongoing. Redevelopment Renewable Energy Development Underway This project will be the largest solar installation at a Superfund site. Two pharmaceutical manufacturing facilities are active on the northern part of the site. Solar developer Clean Flexible Energy, LLC submitted a proposal for an 80-megawatt solar generation and 110-megawatt storage facility on the southern part of the site. The proposed project area covers about 306 acres; about 243 acres of this area is on-site. Project construction started in September 2024. The project is expected to be operational by the end of 2025. It will have an estimated useful life of 25 to 30 years. r€> Jobos2 FORMER CANE FIELD Figure 2.
