EPA finds that the Toa Alta Heights WWTP is unable to meet the water quality based effluent limits set out in its NPDES permit and that PRASA is not maintaining and operating the facility adequately. This Administrative Order (AO) requires PRASA to maximize the operation and maintenance of the Toa Alta Heights WWTP in order to achieve and maintain compliance with all the final effluent limitations. In additon, this AO requires PRASA to submit a plan that outlines a schedule, for the completion of all permanent repairs/takss needed to correct the deficiencies found during a compliance evaluation inspection conducted on September 17, 2003.
