Environmental Protection Agency August 19, 2013 – Federal Register Recent Federal Regulation Documents

On February 6, 2013, EPA proposed to approve revisions to the State of Michigan's Clean Air Act State Implementation Plan (SIP) that Michigan had submitted on March 24, 2009. Michigan's submittal included revisions to Part 1, Definitions; Part 2, Air Use Approval; and Part 19, New Source Review for Sources Impacting Nonattainment Areas, of the Michigan rules. EPA is revising the February 6, 2013, proposed approval to announce that we will not take action on the changes to Part 2 Air Use Approval rules and of the Part 2 revision submittals on November 12, 1993, May 16, 1996, April 3, 1998, September 2, 2003, and March 24, 2009, at this time. EPA is proposing to rescind Michigan's rule 336.1220 from its SIP. Michigan included this request to rescind this portion of the rule in its March 24, 2009, submittal as part of the Part 19 New Source Review rule approval. The rescission of rule 336.1220 will eliminate having differing nonattainment rules in the State SIP.

The California Air Resources Board (CARB) has notified EPA that it has adopted amendments to the California Spark Ignition Marine Engine and Boat Regulations (2008 Marine SI Amendments or 2008 Amendments). CARB requested EPA confirmation that some of the 2008 Amendments are within the scope of prior EPA authorizations or alternatively that EPA grant full authorization for those amendments. CARB also requested confirmation that additional amendments require and merit full authorization. This notice announces that EPA has tentatively scheduled a public hearing and is now accepting written comment on California's request for authorization of the 2008 Marine SI Amendments.
