40 CFR Part 52
[EPA-R08-OAR-2007-0622; FRL-8490-5]
Approval and Promulgation of Air Quality Implementation Plans;
State of Colorado; Revised Denver PM10 Maintenance Plan
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to take direct final action approving a State
Implementation Plan (SIP) revision submitted by the State of Colorado.
On September 25, 2006, the Governor's designee submitted a revised plan
for particulate matter with an aerodynamic diameter, less than or equal
to 10 microns (PM10) for the Denver metropolitan area for the PM10
National Ambient Air Quality Standard (NAAQS). This revised maintenance
plan addresses maintenance of the PM10 standard for a second ten-year
period beyond redesignation, extends the horizon years, and contains
revised transportation conformity budgets. EPA is approving the removal
of Regulation No. 11, ``Motor Vehicle Emissions Inspection Program''
from Denver's revised PM10 maintenance plan. In addition, EPA is
approving a transportation budget trading protocol for estimating the
PM10 and nitrogen oxides (NOx) for each conformity determination. This
action is being taken under section 110 of the Clean Air Act.
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
[[Page 62616]]
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 the 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.
