Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; PM-10 Test Methods

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.


SUMMARY: EPA proposes to approve the State Implementation Plan (SIP) 
revision submitted by the State of Maryland for the purpose of 
incorporation by reference of EPA approved test methods for stack 
testing for particulate matter with a particle size of 10 microns or 
less (PM-10). In the Final Rules section of this Federal Register, EPA 
is approving the State's SIP submittal as a direct final rule without 
prior proposal because the Agency views this as a noncontroversial 
submittal 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 action, no further activity 
is contemplated. 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rule will be withdrawn and all public comments received will be 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. EPA 
will not institute a second comment period. Any parties interested in 
commenting on this action should do so at this time.

DATES: Comments must be received in writing by February 2, 2007.
