AES Puerto Rico has 5 groundwater monitoring wells, 4 of which have been polluted above federal advisory levels based on samples collected between August 08, 2017 and September 23, 2019. Groundwater at this site contains unsafe levels of sulfate, molybdenum, lithium, selenium, boron and arsenic.Site description AES Puerto Rico LP operates a 510-MW coal-fired power plant located in the municipality of Guayama, on the south coast of Puerto Rico. The Site has an approximate total area of 101 acres. The power plant uses bituminous coal for energy production, generating coal combustion residuals in the form of coal ash and is currently being converted to renewable power. The CCR is converted to a manufactured aggregate known as Agremax that is stored in a temporary Agremax stockpile storage area that is located near the southern property boundary. The Agremax Storage Area is regulated under the CCR rule. You can find the industry-reported data here. For more information on the AES Puerto Rico, see EIP’s 2019 National Coal Ash Report.
