EPA finds that the Cayey Wastewater Treatment Plant (WWTP) is unable to meet the water quality based effluent limits set out in its NPDES permit and that PRASA is not maintaning and operating the facility adequately. This Administrative Order (AO) requires PRASA to maximize the operation and maintenace of the Cayey WWTP in order to achieve and maintain compliance with all the final effluent limitations. In addition, this AO requires PRASA to submit a compliance plan that outlines a schedule, for the completion of all permanent repairs/tasks needed to correct the deficiencies found during a compliance evaluation inspection conducted on June 6, 2002.
