ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52

[CT27-1-7200b; A-1-FRL-5667-3]


Clean Air Act Approval and Promulgation of State Implementation 
Plans; Connecticut: PM10 Prevention of Significant Deterioration 
Increments; and Approval of a Second 1-Year Extension of PM10 
Attainment Date for New Haven

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing full approval of a State Implementation Plan 
(SIP) revision submitted by the State of Connecticut, which replaces 
the total suspended particulate (TSP) prevention of significant (PSD) 
increments with increments for PM10 (particulate matter with an 
aerodynamic diameter less than or equal to a nominal 10 micrometers). 
EPA is also proposing full approval of Connecticut's request for a 
second 1-year extension of the attainment date for the New Haven PM10 
nonattainment area, based on monitored air quality data for the 
national ambient air quality standard for PM10 during the years 1993-
95. These actions are being taken under the Clean Air Act. In the Final 
Rules Section of this Federal Register, EPA is approving the 
Connecticut's SIP revision and extension request as a direct final rule 
without prior proposal because the Agency views this as a 
noncontroversial revision and anticipates no adverse comments. A 
detailed rationale for the approval is set forth in the direct final 
rule. If no adverse comments are received in response to that direct 
final rule, no further activity is contemplated in relation to this 
proposed rule. If EPA does receive adverse comments, the direct final 
rule will be withdrawn and all public comments received will be 
addressed in a subsequent final rule based on this proposed rule. EPA 
will not institute a second comment period on this proposal. Any 
parties interested in commenting on this proposal should do so at this 
time.

DATES: Comments must be received on or before April 25, 1997.

ADDRESSES: Comments may be mailed to Susan Studlien, Deputy Director, 
Office of Ecosystem Protection, EPA--Region 1, JFK Federal Bldg (CAA), 
Boston, MA 02203. Copies of Connecticut's submittal and EPA's technical 
support document are available for public inspection by appointment
