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.
