Approval and Promulgation of State Implementation Plan; Ohio

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule.

SUMMARY: The United States Environmental Protection Agency (USEPA) is 
proposing to approve a June 10, 1997, request from Ohio, for a State 
Implementation Plan (SIP) maintenance plan revision for the following

Akron-Lorain area (including Lorain, Cuyahoga, Lake, Ashtabula, Geauga, 
Medina, Summit and Portage counties), and the Dayton-Springfield area

maintenance plan revisions are requesting to allocate to the mobile

maintenance plan.

September 24, 1997.
