Continues to implement oxy program. TNRCC
expanded the federal control period to begin Oct. 1 and
end on March 31.

Redesignated to attainment 12/14/02 (66FR 64751).
Oxy program in the maintenance plan


Redesignated to attainment 9/24/99 (64 FR 51694).
Oxy program in the maintenance plan.


Submitted redesignation request to attainment. Will
continue to implement program.
EPA is pursuing enforcement discretion through Spring
2006, pending rule making which would eliminate
winter oxygen requirement in the SIP
Final redesignation to CO "serious" non- attainment
area was published in the FR on 10-2-97 (62 FR 51604-
51606). Approval of wintertime oxygenated fuel
program in June 1999 (64 FR 29573). Approval of low
RVP and CBG programs finalized, effective October
21,2004. (69 FR 56351).
Most recent SIP revision requires gasoline similar to
CARB Phase 2 in winter, with 10% ethanol. (see 60
FR 10161, March 4, 2004) We have proposed to
redesignate the area to attainment (10/8/04, 69 FR
60328). The maintenance plan submittal makes no
changes to the oxygenated fuel program. See
discussion at 60334-5.
OXY & RFG
Classified as a "serious" CO non-attainment area. Has
data to redesignate - working on redesignation request.

Comments
EPA audited in Jan. '94. Has data to redesignate -
working on redesignation request.
Program is part of the CO maintenance plan
Redesignation plan, effective September 2, 1997, kept
oxy program in the maintenance plan. Proposed
maintenance plan revision will remove oxy program in
2007 except as a contingency measure..
Oxy program in the approved maintenance plan
provides for increase up to 3.5%
