Advance Notice of Proposed Rulemaking on Lead Emissions From 
Piston-Engine Aircraft Using Leaded Aviation Gasoline; Extension of 
Comment Period

AGENCY: Environmental Protection Agency (EPA).

ACTION: Advance notice of proposed rulemaking; extension of comment 
period.

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

SUMMARY: EPA is announcing a 60-day extension of the public comment 
period for the Advance Notice of Proposed Rulemaking on Lead Emissions 
From Piston-Engine Aircraft Using Leaded Aviation Gasoline (hereinafter 
referred to as the ANPR). EPA published this ANPR, which included a 
request for comment, in the Federal Register on April 28, 2010. The 
public comment period was to end on June 28, 2010 (60 days after its 
publication in the Federal Register). This document extends the comment 
period an additional 60 days until August 27, 2010. This extension of 
the comment period is provided to allow the public additional time to 
provide comment on the ANPR.

DATES: The comment period for the ANPR published April 28, 2010 (75 FR 
22440) is extended. Written comments must be received on or before 
August 27, 2010.

SUPPLEMENTARY INFORMATION:
    Background: In the ANPR, EPA described and invited comment from all 
interested parties on the data available for evaluating lead emissions, 
ambient concentrations and potential exposure to lead from the use of 
leaded aviation gasoline (avgas) in piston-engine powered aircraft. The 
ANPR is one of the steps EPA has taken in response to a petition 
submitted by Friends of the Earth (FOE) requesting that EPA find 
endangerment from and regulate lead emitted by piston-engine aircraft, 
or if insufficient information exists, to commence a study. In addition 
to describing and inviting comment on the current data, the ANPR also 
describes considerations regarding emission engine standards and 
requests comment on approaches for transitioning the piston-engine 
fleet to unleaded avgas.
    Extension of Comment Period: EPA received requests for an extension 
of the ANPR comment period that are available in the docket for this 
rule (EPA-HQ-OAR-2007-0294). After considering the requests, EPA has 
determined that a 60-day extension of the comment period would provide 
the public adequate time to provide meaningful comment on the ANPR. 
Accordingly, the public comment period for the ANPR is extended until 
August 27, 2010. EPA does not anticipate any further extension of the 
comment period at this time.
