        <RULE_TITLE>Second 6 Year Review of Existing National Primary Drinking Water Regulations</RULE_TITLE>
        <ABSTRACT><![CDATA[The Safe Drinking Water Act (SDWA) requires EPA to review and revise, if appropriate, all National Primary Drinking Water Regulations (NPDWRs) no less frequently than once every six years. According to SDWA, any revisions of drinking water regulations must maintain, or increase, the level of public health protection provided; however, EPA may identify regulatory changes that will streamline or reduce existing requirements without lessening the level of public health protection. As part of this action, the Office of Water (OW) will implement the existing protocol for conducting each six year review (developed under the first six year review cycle) to review critical elements for regulated chemical contaminants (e.g., health risks, occurrence, analytical methods, treatment technologies). No new requirements will be imposed by this action. The purpose of the review is to determine whether new data, technology, or other factors exist that justify revisions to existing NPDWRs. The outcome of the review will be a Federal Register notice making available the results of the Agency's review and recommendations for any regulations the Agency may consider revising. Because this action does not change or add to existing requirements, OW will not be performing a formal economic analysis or consulting with small businesses, governments, or tribal officials. OW does not plan to generate new data as part of this action; the review will be based on recent compliance data from public water systems and existing data on health effects (such as completed IRIS and OPPTS health risk assessments) and analytical methods.]]></ABSTRACT>
