THE EARTH ON LEADED AVGAS
Part of the push to eliminate
tetraethyl lead avgas comes for the California-based environmental group
Friends of the Earth. They've asked the EPA to examine lead emissions
and declare a finding of endangerment as the first step in regulations
that would eliminate lead as an octane enhancer. But thus far, FOE has
only filed an administrative petition and won't say at this point if it
will follow up with a lawsuit to force EPA's hand. The petition has been
in place for four years. In this podcast, FOE's Marcie Keever
tells AVweb that it's sensitive to economic considerations for
aircraft owners and operators, but, ultimately, it can only ask EPA to
write the regulations, and it can't negotiate on what amount of lead
emissions are acceptable.
