Clean Air Act Approval and Promulgation of State Implementation

Plan; Colorado; Revisions Regarding Negligibly Reactive Volatile

Organic Compounds and Other Regulatory Revisions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA approves three revisions to the Colorado State

Implementation Plan (SIP). The SIP revisions being approved include: an

update to the State's list of negligibly reactive volatile organic

compounds (VOCs) to add acetone. The State also consolidated the list

of negligibly reactive VOCs from Regulations No. 3 and 7 into the

Common Provisions Regulation. These revisions were submitted for

approval on September 16, 1997; a clarification to the definition of

``applicable requirement'' and corrections of typographical errors in

parts A and B of Colorado Regulation No. 3. These revisions were also

submitted on September 16, 1997; and an update to the list of

negligibly reactive VOCs in the Common Provisions Regulation to add

perchloroethylene. The State also repealed its requirements in

Regulation No. 7 that required control of VOC emissions from dry

cleaning facilities using perchloroethylene as a solvent. These

revisions were submitted for approval on August 19, 1998.

In the ``Rules and Regulations'' section of this Federal Register,

we approve the State's submittals as a direct final rule without prior

proposal because we view this as a noncontroversial action and

anticipate no adverse comments. A detailed rationale for the approval

is set forth in the preamble of the direct final rule. If no adverse

comments are submitted, we will not take further action on this

proposed rule. If we receive adverse comments, we will publish a timely

withdrawal of the direct final rule in the Federal Register and it will

not take effect. We will address all public comments in a subsequent

final rule based on this proposed rule. We will not institute a second

comment period on this action. Any parties interested in commenting

must do so at this time.

DATES: Comments must be received in writing on or before before July

19, 1999.

ADDRESSES: You should mail your written comments to Richard R. Long,

Director, Air and Radiation Program, Mailcode 8P-AR, Environmental

Protection Agency (EPA), Region VIII, 999 18th Street, Suite 500,

Denver, Colorado, 80202. Copies of the documents relative to this

action are available for inspection during normal business hours at the
