ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[WA 68-7143-b; FRL-6322-4]

Approval and Promulgation of State Implementation Plans:

Washington

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA proposes to approve the State Implementation Plan

(SIP) revision to the particulate matter with an aerodynamic diameter

less that or equal to nominal 10 micrometers (PM-10) SIP for the

Spokane PM-10 nonattainment area submitted by the State of Washington

and received at EPA on March 2, 1999. The revision, makes minor

revisions to two sections of the Spokane County Air Pollution Control

Authority's Regulation I, Article IV. The SIP revision was submitted by

the State to satisfy certain Federal Clean Air Act requirements for a

PM-10 nonattainment plan. In the Final Rules section of this Federal

Register, the 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 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 action, no further activity is contemplated. If the 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adverse comments, the direct final rule will be withdrawn and all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. Any parties interested in commenting on this action

should do so at this time.

DATES: Written comments must be received in writing by May 12, 1999.

ADDRESSES: Written comments should be addressed to Montel Livingston,

Environmental Protection Specialist (OAQ-107), Office of Air Quality,

at the EPA Regional Office listed below. Copies of the state submittal

are available at the following addresses for inspection during normal

business hours. The interested persons wanting to examine these

documents should make an appointment with the appropriate office at

least 24 hours before the visiting day.
