Approval and Promulgation of Air Quality Implementation Plans; Colorado;
 

Revisions to Regulation Number 1
 

AGENCY: EnvirOlunental Protection Agency (EPA). 

ACTION: Proposed Rule 

SUMMARY: EPA is proposing to approve State Inlplenlentation Plan revisions submitted by 

the State of Colorado on August 3, 2007 to Colorado's Regulation Nunlber 1 (revisions to the 

perfonllance testing requirel11ents for air curtain destnlctors). Colorado adopted these rule 

revisions on October 2, 2006. All other actions subnlitted by the State of Colorado concurrent 

with Colorado's Regulation NWllber 1 revision request will be acted on at a later date. 1n 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 11oncontroversial SIP revision and anticipates no adverse comnlents. A detailed rationale for the 

approval is set forth in the preatnble to the direct final rule. If EPA receives no adverse 

C0111nlents, EPA will not take ftu1her action on this proposed rule. If EPA receives adverse 

cOlnnlents, EPA will withdraw the direct tinal rule and it will not take effect. EPA will address 

all public comnlents in a subsequent final rule based on this proposed rule. EPA will not 

institute a second conunent period on this action. Any parties interested in conUl1enting must do 

so at this tilne. Please note that if EPA receives adverse conlment on an alnendlnent, paragraph. 

or section of this rule and if that provision may be severed from the renlainder of the rule, EPA 
nlay adopt as final those provisions of the rule that are not the subject of an adverse COIU111ent.
 

DATES: C0111lnents lnust be received on or before [insert date 30 days after publication in the
 

Federal Register].
