Approval and Promulgation of Air 

Quality Implementation Plans; 

Colorado; Revisions to Regulation 

Number 1 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed Rule. 

SUMMARY: EPA is proposing to approve 

State Implementation Plan revisions 

submitted by the State of Colorado on 

August 3, 2007 to Colorado’s Regulation 

Number 1 (revisions to the performance 

testing requirements for air curtain 

destructors). Colorado adopted these 

rule revisions on October 2, 2006. All 

other actions submitted by the State of 

Colorado concurrent with Colorado’s 

Regulation Number 1 revision request 

will be acted on at a later date. In the 

‘‘Rules and Regulations’’ section of this 

Federal Register, EPA is approving the 

State’s SIP revision as a direct final rule 

without prior proposal because the 

Agency views this as a noncontroversial SIP revision and 

anticipates no adverse comments. A 

detailed rationale for the approval is set 

forth in the preamble to the direct final 

rule. If EPA receives no adverse 

comments, EPA will not take further 

action on this proposed rule. If EPA 

receives adverse comments, EPA will 

withdraw the direct final rule and it will 

not take effect. EPA will address all 

public comments in a subsequent final 

rule based on this proposed rule. EPA 

will not institute a second comment 

period on this action. Any parties 

interested in commenting must do so at 

this time. Please note that if EPA 

receives adverse comment on an 

amendment, paragraph, or section of 

this rule and if that provision may be 

severed from the remainder of the rule, 

EPA may adopt as final those provisions 

of the rule that are not the subject of an 

adverse comment. 

DATES: Comments must be received on 

or before June 9, 2010.

Do not submit information that you

docket and made available on the 

Internet. If you submit an electronic 

comment, EPA recommends that you 

include your name and other contact 

information in the body of your 

comment and with any disk or CD–ROM 

you submit. If EPA cannot read your 

comment due to technical difficulties 

and cannot contact you for clarification, 

EPA may not be able to consider your 

comment. Electronic files should avoid 

the use of special characters, any form 

of encryption, and be free of any defects

SUMMARY: EPA is proposing to approve 

revisions to the Yolo-Solano Air Quality

revisions concern oxides of nitrogen 

(NOx) emissions from natural gas-fired 

water heaters, small boilers and nitric 

acid production facilities. We are 

proposing to approve local rules to 

regulate these emission sources under 

the Clean Air Act as amended in 1990

SUPPLEMENTARY INFORMATION: This 

proposal addresses the following local 

rules: 

1. Rule 2.37, Natural Gas-Fired Water 

Heaters and Small Boilers 

2. Rule 2.42, Nitric Acid Production. 

In the Rules and Regulations section 

of this Federal Register, we are 

approving these local rules in a direct 

final action without prior proposal 

because we believe these SIP revisions 

are not controversial. If we receive 

adverse comments, however, we will 

publish a timely withdrawal of the 

direct final rule and address the 

comments in subsequent action based 

on this proposed rule. Please note that 

if we receive adverse comment on an 

amendment, paragraph, or section of 

these rules and if that provision may be 

severed from the remainder of these 

rules, we may adopt as final those 

provisions of the rules that are not the 

subject of an adverse comment. 

We do not plan to open a second 

comment period, so anyone interested 

in commenting should do so at this 

time. If we do not receive adverse 

comments, no further activity is 

planned. For further information, please 

see the direct final action.
