ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[CA 164-0112b; FRL-6324-9]


Approval and Promulgation of Implementation Plans; California 
State Implementation Plan Revision; Sacramento Metropolitan Air Quality 
Management District (SMAQMD), Mojave Desert Air Quality Management 
District (MDAQMD), and the Ventura County Air Pollution Control 
District (VCAPCD) as Revisions to the California State Implementation 
Plan (SIP)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve revisions to the California State 
Implementation Plan (SIP) which concern the control of oxides of 
nitrogen (NOX) emissions from rules from Sacramento 
Metropolitan Air Quality Management District (SMAQMD), Mojave Desert 
Air Quality Management

[[Page 19331]]

District (MDAQMD), and the Ventura County Air Pollution Control 
District (VCAPCD) as revisions to the California State Implementation 
Plan (SIP). SMAQMD's Rule 414 controls emissions of oxides of nitrogen 
from natural gas-fired water heaters; MDAQMD's Rule 1157 controls 
emissions from boilers and process heaters; and VCAPCD's Rule 74.16 
controls emissions of oxides of nitrogen from oilfield drilling 
operations.
    The intended effect of proposing approval of these rules is to 
regulate NOX emissions in accordance with the requirements 
of the Clean Air Act, as amended in 1990 (CAA or the Act). In the final 
rules Section of this Federal Register, the EPA is approving the 
state's SIP submittal as direct final rule without prior proposal 
because the Agency views this as a noncontroversial revision and 
anticipates no adverse comments. A detailed rationale for this approval 
is set forth in the direct final rule. If no adverse comments are 
received, no further activity is contemplated. If 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comments, the direct final rule will be withdrawn and all public 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 should do so at this time.

DATES: Written comments must be received by May 20, 1999.

ADDRESSES: Comments should be addressed to: Andrew Steckel, Rulemaking 
Office, AIR-4, Air Division, U.S. Environmental Protection Agency, 
Region IX, 75 Hawthorne Street, San Francisco, CA 94105-3901.

available for public inspection at EPA's Region 9 office during normal 
business hours. Copies of the submitted rules revisions are also
