SUPPLEMENTARY INFORMATION! On july 

26, 1994, EPA published a direct final 

notice (see 59 FR 37939) redesignating 

the Memphis/Shelby County area from 

nonattainment to attainment for CO. 

That notice stated the effective date of 

the redesignation would be September. 

26, 1994, if no _adverse cOmments Were 

received._ No adverse comments have 

been received. Subsequently, on August 

4, 1994, EPA published a rule (see 59 FR 

39832) identifying areas with findings 

in place that would be subject to 

sanctions under the Clean Air Act (the 

Act) as amended in 1990. This action 

becomes effective on September 6, 1994. 

The Memphis/Shelby County, 

Tennessee, CO nonattainment area was 

identified as one of the areaa which 

would be subject to sanctionS under 

. section 179(A) of the Act beginning on 

September 6, 1994. 

The 18-month clock leading to the 

imposition of these sanctions was 

started by a letter dated january 15, 

1993, in which EPA found that the State 

. of Tennessee had failed to submit a state' 

implementation plan (SIP) for an 

OXygenated fuels program and 

corrections to a basic inspections/ 

maintenance program by November 15, 

1992. These sanctions would be lifted 

once the redesignation becomes 

effective. 

Under the timetable established by the August 4, 1994, sanction rule and 

the July 26, 1994, redesignation notice, 

sanctions would be in place from 

September 6, 1994, to September 26, 

1994, the effective date established in 

the July 26, 1994, redesignation notice. 

In order to pi'eVent the imposition of 

SanctiOns for a three week period on an 

area whose redesignation to attainment 

has been approved, EPA is hereby 

accelerating the effective date of the 

· 26, 1994 (59 FR 37939),amending 40 

CFR 52.2220 and§ 81.343 is effective 

August 31, 1994, under the authority of 

the Clean Air Act (42 U.S.C. 7401-

7671q). 

Nothing in this action shall be 

construed as permitting or .allowing or 

establishing a precedent for any future 

request for a revision to any SIP. Each 

request for revision to the SIP shall be 

considered separately in light of specific 

technical, economic, and environmental 

faCtors and in relation to relevant 

statutory and regulatory requirements.
