Promulgation of State Implementation Plan Revisions; Infrastructure Requirements for the 1997 and 2006 PM2.5
The Environmental Protection Agency (EPA) is proposing to approve elements of State Implementation Plan (SIP) revisions from the State of South Dakota to demonstrate the State meets infrastructure requirements of the Clean Air Act (CAA) for the National Ambient Air Quality Standards (NAAQS) promulgated for particulate matter (PM) on July 18, 1997 and October 17, 2006; lead (Pb) on October 15, 2008; ozone on March 12, 2008; and nitrogen dioxide (NO2) on January 22, 2010. EPA is also proposing to approve SIP revisions the State submitted updating the Prevention of Significant Deterioration (PSD) program and provisions regarding state boards. Section 110(a) of the CAA requires that each state submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA.
Approval and Promulgation of Air Quality Implementation Plans; Massachusetts; Transit System Improvements
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Massachusetts on November 6, 2013. This proposal, if finalized, would remove the design of the Red Line/Blue Line Connector as a requirement in the Massachusetts SIP, without substitution or replacement, and would implement administrative changes that lengthen the existing public process by fifteen days and replace references to the Executive Office of Transportation (EOT) with references to the Massachusetts Department of Transportation (MassDOT). This action is being taken under the Clean Air Act.
Approval and Promulgation of Air Quality Implementation Plans; State of Montana Second 10-Year Carbon Monoxide Maintenance Plan for Great Falls
The Environmental Protection Agency (EPA) is proposing approval of a State Implementation Plan (SIP) revision submitted by the State of Montana. On July 13, 2011, the Governor of Montana's designee submitted to EPA a second 10-year maintenance plan for the Great Falls area for the carbon monoxide (CO) National Ambient Air Quality Standard (NAAQS). This maintenance plan addresses maintenance of the CO NAAQS for a second 10-year period beyond the original redesignation. EPA is also proposing approval of an alternative monitoring strategy for the Great Falls CO maintenance area, which was submitted by the Governor's designee on June 22, 2012.
Approval and Promulgation of Implementation Plans; State of Iowa; 2014 Iowa State Implementation Plan
The Environmental Protection Agency (EPA) is taking final action to approve a revision to the State Implementation Plan (SIP) for the State of Iowa. This final action will approve a revision to Iowa's SIP for the 2006 24-hour PM2.5 National Ambient Air Quality Standards (NAAQS). The proposed action was published in the Federal Register on August 11, 2014. As stated in the proposal, the SIP revision submitted by the state satisfies the applicable requirements of the Clean Air Act (CAA) and will keep the Muscatine County, Iowa area in attainment of the 2006 24-hour PM2.5 NAAQS.
NPDES Electronic Reporting Rule
On July 30, 2013, the Environmental Protection Agency (EPA) proposed the NPDES Electronic Reporting Rule that would require electronic reporting instead of current paper-based NPDES reports. This action would modernize NPDES reporting, save time and resources for regulated entities and regulatory agencies, better protect the Nation's waters by improving compliance, and provide the public with access to information that affects their communities. The proposal would enhance transparency and accountability by providing regulatory agencies and the public with more timely, complete, accurate, and nationally- consistent data about the NPDES program and potential sources of water pollution. The benefits of this proposed rulemaking should allow NPDES- authorized programs in states, tribes, and territories to shift precious resources from data management activities to solving issues that threaten human health, water quality, and noncompliance issues. As a result of comments received on the proposed rule, we are soliciting further comments by opening a new public comment period.
