SUMMARY: The FAA is issuing this notice to advise the public that FAA

at Denver International Airport (DEN) and to request comments from the 
public on the DGCD. In accordance with Section 176(c) of the Clean Air 
Act, FAA has assessed whether the emissions that would result from 
FAA's action in approving the proposed operation specifications 
(OPSPECS) for Lynx Aviation's proposed operations at DEN conform to the 
applicable Colorado State Implementation Plans (SIPs). The DGCD 
contains this assessment.

DATES: Submit comments on or before August 20, 2007.

ADDRESSES: Interested parties may view hard copies of the document in 
Denver, Monday through Friday, from 8 a.m. to 4 p.m. Mountain Daylight 
Time at Environmental Services Section, Department of Aviation, City 
and County of Denver, Elrey B. Jeppesen Terminal Building, Level 6, 
Room 6619-20, 8400 Pe[ntilde]a Boulevard, Denver, CO 80249. Please 
contact Ms. Aimee Fenlon at 303-342-2636 for appointments.

SUPPLEMENTARY INFORMATION: The Denver Metropolitan Area is an EPA-
designated attainment/maintenance area for the criteria pollutants 
carbon monoxide, particulate matter with aerodynamic diameter of 10 
micrometers or less (PM10), and ozone (1-hour standard). In 
addition, DEN is located in an Early Action Compact area for the 8-hour 
ozone standard.
    The FAA demonstrates in the DGCD that the sum of the existing 
aircraft operations at DEN plus the proposed aircraft operations by 
Lynx Aviation is below the forecast values incorporated into the State 
Implementation Plan (SIP), and therefore aircraft emissions attributed 
to flights by Lynx Aviation are already accounted for in the SIP 
emissions inventories. As a result, the FAA can demonstrate that the 
proposed action conforms to the SIP.
