ENVIRONMENTAL PROTECTION AGENCY

[FRL-5955-2]


Guidance for Implementing the 1-Hour Ozone and Pre-Existing 
PM10 National Ambient Air Quality Standards (NAAQS)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability.

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

SUMMARY: Notice is hereby given that the EPA has issued guidance for 
continuing the implementation of the Clean Air Act requirements for the 
1-hour ozone and pre-existing PM10 (particles with an 
aerodynamic diameter less than or equal to a nominal 10 micrometers) 
NAAQS following EPA's promulgation of the new 8-hour ozone (62 FR 
38856, July 18, 1997) and PM (62 FR 38652, July 18, 1997) NAAQS. The 
EPA has issued the guidance to ensure that momentum is maintained by 
the States in their current programs while moving toward developing 
their plans for implementing the new NAAQS, and it applies to all areas 
now subject to the 1-hour ozone standard and the pre-existing 
PM10 standard regardless of attainment status. On July 16, 
1997 (62 FR 38421, July 18, 1997), President Clinton issued a directive 
to EPA Administrator Browner on implementation of the new standards for 
ozone and PM. In that directive, the President laid out a plan on how 
these new standards, as well as the current 1-hour ozone and pre-
existing PM standards, are to be implemented. The guidance reflects the 
Presidential Directive.

ADDRESSES: Copies of the guidance are available from the World Wide Web 
site listed in SUPPLEMENTARY INFORMATION.

FOR FURTHER INFORMATION CONTACT: For specific questions and comments on 
the ozone portion of this guidance, contact Ms. Sharon Reinders, U.S. 
EPA, MD-15, Research Triangle Park, NC 27711, telephone (919) 541-5284; 
for specific questions and comments on the PM portion of this guidance, 
contact Ms. Robin Dunkins, U.S. EPA, MD-15, Research Triangle Park NC 
27711, telephone (919) 541-5335.

SUPPLEMENTARY INFORMATION: The purpose of this guidance is to set forth 
EPA's current views on key issues regarding the ongoing programs 
implemented by State, local and tribal air pollution control agencies 
to attain the 1-hour ozone and pre-existing PM10 NAAQS. 
These issues will be addressed in future rulemakings as appropriate. 
The EPA will propose to take a particular action based in whole or in 
part on its views of the relevant issues, and the public will have an 
opportunity to comment on EPA's interpretations during the rulemakings. 
When EPA issues final rules based on its reviews, those views will be 
binding on the States, the public, and EPA as a matter of law.
