Public notice is hereby given that the Commonwealth of Puerto Rico has revised its approved Public Water System Supervision Program. Puerto Rico has adopted drinking water regulations for the Consumer Confidence Report Rule Revisions. The Environmental Protection Agency (EPA) has determined that Puerto Rico's revised regulations meet all minimum Federal requirements, and that they are no less stringent than the corresponding Federal regulations. Therefore, the EPA has decided to tentatively approve the Territory program revisions. All interested parties may request a public hearing.
