Approval and Promulgation of Air Quality Implementation Plans;
Louisiana: Revision to the State Implementation Plan (SIP) for the
Ozone Maintenance Plan for St. James Parish
AGENCY: Environmental Protection Agency.
ACTION: Proposed rule; reopening of comment period.
-----------------------------------------------------------------------
SUMMARY: We are reopening our proposal to approve a revision to the
Louisiana SIP for the St. James Parish ozone maintenance area,
submitted by Louisiana on April 23, 1998. The revision includes an
adjustment to the volatile organic compound emission inventory for the
1990 base year of the approved maintenance plan, and changes to the
approved contingency plan's triggers and control measures. We have
received a request to extend the comment period an additional two
weeks. The requesters need the additional time to review the initial
simulation results of the Urban Airshed Modeling demonstration
submitted with this SIP revision. In order to ensure that all
interested parties have sufficient opportunity to submit comments, we
will re-open the comment period for the St. James Parish SIP revision.
Please review our reasons for proposing approval of the St. James
Parish SIP revision, as published in the Federal Register on January
14, 1999 (64 FR 2455).
DATES: Comments received on or before March 29, 1999, including those
received between the close of the comment period on February 16, 1999,
and the publication of this document, will be entered into the public
record and considered by the EPA before taking final action.
