ACTION: Proposed rule; re-opening of public comment deadline.

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

SUMMARY: By this action, EPA is re-opening the public comment period

from July 20, 1998, to August 19, 1998, the deadline for receiving

written comments on two Agency proposed actions: the redesignation of

the Power-Bannock Counties PM-10 nonattainment area, and a finding that

the proposed Fort Hall nonattainment area failed to attain the National

Ambient Air Quality Standard (NAAQS) for particulate matter of less

than ten micrometers in aerodynamic diameter (PM-10).

DATES: Comments must be received or postmarked on or before August 19,

1998.

ADDRESSES: Copies of the request and other information supporting this

proposed action are available for inspection during normal business

SUPPLEMENTARY INFORMATION: On June 19, 1998 (63 FR 33597), EPA

solicited public comment on its proposal to redesignate the Power-

Bannock Counties PM-10 nonattainment area by creating two distinct

nonattainment areas that together cover the identical geographic area

as the original nonattainment area. Likewise, on June 19, 1998 (63 FR

33605), EPA solicited public comment on a concurrent proposal to find

that a portion of the Fort Hall Indian Reservation had failed to attain

the PM-10 NAAQS by the applicable attainment date of December 31, 1996.

EPA received a request to extend the public comment period to allow

more time to prepare a comprehensive comment document.

As a result of a request to extend the public comment period, EPA

is granting a 30-day extension. A copy of this request has been placed

into the docket and may be reviewed during normal business hours at the

following location: Office of Air Quality (OAQ-107), Environmental

Protection Agency, 1200 Sixth Avenue Seattle, Washington 98101.

Interested parties are invited to comment on all aspects of EPA's two

proposals of June 19, 1998. Comments should be submitted, preferably in

triplicate, to the address listed in the front of this document.

Dated: July 24, 1998.
