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.

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 pistonengine
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.
