Clean Air Act Approval and Promulgation of PM10 Contingency

Measure Plans for Canon City and Lamar, CO

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of proposed rulemaking.

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

SUMMARY: EPA proposes to fully approve the contingency measures

submitted by the State of Colorado on December 9, 1993, for the

nonattainment areas of Canon City and Lamar, for particulate matter

with an aerodynamic diameter less than or equal to a nominal 10

micrometers (PM10). The submittal was made in accordance with the

requirements specified under section 172(c)(9) of the Clean Air Act

(Act). In the final rules section of this Federal Register, EPA is

approving the State Implementation Plan (SIP) revision as a 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 does receive adverse comments, however, then the

direct final rule will be withdrawn, and all public comments received

will be addressed in a subsequent final rule based upon this proposed

rule. EPA will not institute a second comment period on this document.

Any parties interesting in commenting on this action should do so at

this time.

DATES: Comments on this proposed rule must be received in writing by

January 13, 1995.

ADDRESSES: Written comments on this action should be addressed to Vicki

Stamper (8ART-AP), Air Programs Branch, at the EPA Regional Office

listed below. Copies of the documents relevant to this proposed rule

are available for public inspection during normal business hours at the

following locations. The interested persons wanting to examine these

documents should make an appointment with the appropriate office at

least 24 hours before the visiting day.
