ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[IL196-2; MO 109-1109; FRL-6844-5]


Approval and Promulgation of Implementation Plans: Illinois and
Missouri: Ozone

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; reopening of the public comment period.

-----------------------------------------------------------------------

SUMMARY: EPA is reopening the public comment period for a proposed rule
published on April 17, 2000 (65 FR 20404). In the April 17, 2000
proposed rule, EPA proposed to approve the Illinois and Missouri 1-hour
ozone attainment demonstration State Implementation Plans for the St.
Louis moderate ozone nonattainment area. In the alternative, EPA
proposed to disapprove the attainment demonstration if: Illinois and
Missouri did not revise the attainment demonstration modeling and
analyses to incorporate corrections to the 1999 base year emissions
inventory and successfully demonstrate attainment of the 1-hour
standard based on the revised modeling; Illinois or Missouri did not
submit proposed regional oxides of nitrogen (NOX) emission
control regulations for electric generating units (EGUs) by June 2000
and final adopted regional NOX emission control regulations
for EGUs by December 2000; and, Missouri did not submit a proposed
motor vehicle emissions budget by June 30, 2000. In the April 17, 2000
proposed rule, EPA also proposed to approve an exemption from NOX
emission control requirements for reasonably available control
technology (RACT) for the Illinois portion of the St. Louis ozone
nonattainment area, to extend the ozone attainment date for the entire
St. Louis ozone nonattainment area to November 15, 2003, and, to
approve the transportation conformity motor vehicle emissions budget
submitted by Illinois for the Illinois portion of the St. Louis ozone
nonattainment area. Final approval of the extension of the ozone
attainment date and the motor vehicle emission budgets are contingent
on the final approval of the ozone attainment demonstration. Final
approval of the attainment demonstration is contingent on the final
approval of the regional NOX emission control regulations
and on the submittal of adequate motor vehicle emissions budgets. Final
approval of the NOX RACT exemption for Illinois is
contingent on final approval of an attainment demonstration that does
not rely on NOX emission reductions resulting from NOX
RACT implementation in the Illinois portion the St. Louis ozone
nonattainment area. In the April 17, 2000 proposed rule, EPA proposed
to disapprove Illinois' request for an exemption from NOX
requirements for New Source Review and general conformity. EPA received
a request to extend the public comment period.
