Air Quality State Implementation Plans; Approval and Promulgation: Missouri; 2013 State Implementation Plan for the 2008 Lead Standard
Document Number: 2014-24759
Type: Rule
Date: 2014-10-20
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is taking final action to approve a revision to the State Implementation Plan (SIP) for the State of Missouri. This final action will approve Missouri's SIP for the lead National Ambient Air Quality Standard (NAAQS) nonattainment area of Herculaneum, Missouri. EPA proposed approval of this plan on July 24, 2014. The applicable standard addressed in this action is the lead NAAQS promulgated by EPA in 2008. EPA believes Missouri's SIP satisfies the applicable requirements of the Clean Air Act (CAA) identified in EPA's 2008 Final Rule and will bring the area into attainment of the 0.15 micrograms per cubic meter (ug/m\3\) lead NAAQS in the Herculaneum, Missouri area. In this action, EPA is also finalizing its approval of a revision to the Missouri SIP related to the 2007 Consent Judgment which was previously approved into the Missouri SIP for the 1978 lead NAAQS.
Announcement of Preliminary Regulatory Determinations for Contaminants on the Third Drinking Water Contaminant Candidate List
Document Number: 2014-24582
Type: Proposed Rule
Date: 2014-10-20
Agency: Environmental Protection Agency
The Safe Drinking Water Act (SDWA), as amended in 1996, requires the Environmental Protection Agency (EPA) to make regulatory determinations every five years on at least five unregulated contaminants. A regulatory determination is a decision about whether or not to begin the process to propose and promulgate a national primary drinking water regulation (NPDWR) for an unregulated contaminant. These unregulated contaminants are chosen from the Contaminant Candidate List (CCL), which SDWA requires the agency to publish every five years. EPA published the third CCL (CCL 3) in the Federal Register on October 8, 2009. This notice presents the preliminary regulatory determinations and supporting rationale for 5 of the 116 contaminants listed on CCL 3. The agency is making preliminary determinations to regulate one contaminant (i.e., strontium) and to not regulate four contaminants (i.e., 1,3-dinitrobenzene, dimethoate, terbufos and terbufos sulfone). EPA seeks comment on these preliminary determinations.
