ENVIRONMENTAL PROTECTION AGENCY

40 CFR Parts 52 and 81

[TX60-1-7269; FRL-5870-2]


Approval and Promulgation of State Implementation Plans; Texas; 
Prevention of Significant Deterioration (PSD) Increments for 
Particulate Matter Less Than 10 Microns in Diameter (PM-10); 
Designation of Areas for Air Quality Planning Purposes

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA proposes to approve revisions to the Texas State 
Implementation Plan (SIP) addressing PSD permitting regulations. The 
purpose of this revision is to replace the total suspended particulate 
(TSP) PSD increments with increments for PM-10. In conjunction with 
this proposal, EPA is proposing to remove the TSP area designation 
tables in 40 Code of Federal Regulations part 81 for Texas. With the 
PM-10 increments becoming effective in Texas, the TSP area designations 
no longer serve any useful purpose relative to PSD. The EPA also 
proposes to approve revisions to regulations of the Texas Natural 
Resource Conservation Commission submitted August 31, 1993; the 
recodification of Chapter 116. In the final rules section of this 
Federal Register, EPA is approving the State's SIP revisions as direct 
final rule without prior proposal because the Agency views this as a 
noncontroversial revision amendment 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 
this proposed rule, no further activity is contemplated in relation to 
this rule. If EPA receives 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be withdrawn, and all public comments received will be addressed in a 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. The EPA will not 
institute a second comment period on this action. Any parties 
interested in commenting on this action should do so at this time.

DATES: Comments on this proposed rule must be postmarked by September 
18, 1997.

ADDRESSES: Written comments on this action should be addressed to Ms. 
Jole C. Luehrs, Chief, Air Permits Section (6PD-R), at the EPA Region 6 
office listed below. Copies of documents relevant to this action are
