It is very disappointing to read the questionable results of the lead monitoring at San Carlos Airport. Although the EPA and the Bay Area Air Quality Officials were advised in advance against placing the monitors in the aircraft preflight run-up area, they chose to ignore the warnings and to no one’s surprise came up with the faulty results they published.

EPA: San Carlos Airport has high levels of lead fuel emissions – SAN CARLOS — A U.S. Environmental Protection Agency study of 17 small airports across the country found that San Carlos Airport had the highest concentration of airborne lead particles, measured at a level that exceeds tough new federal standards. (CalPilots Editor’s Note: Even though the EPA was advised that the findings would be inappropriate due to the run-up area monitor location, they continued to use the faulty monitor location – why?).

Lawsuit Against EPA on Aircraft Lead Emissions Fails to Consider Actions Already Underway – Members of the General Aviation (GA) Avgas Coalition say that a lawsuit filed against the Environmental Protection Agency (EPA) by the environmental group Friends of the Earth (FOE) over piston-engine aircraft’s use of leaded aviation gasoline (avgas) is not taking into consideration the considerable work already completed toward the development and deployment of an unleaded solution.

Today we mourn the passing of a beloved old friend, Common Sense in general aviation. It will be remembered as having cultivated such valuable lessons as knowing when to not fly into a storm, life isn’t always fair, and maybe it was pilot error. Common Sense lived by simple, sound principals, including “follow the manufacturer’s recommended maintenance practices” and “the pilot is in charge.”

EPA Issues Proposed Rulemaking for Leaded Avgas
On April 28, 2010, the Environmental Protection Agency (EPA) issued an advance notice of proposed rulemaking (ANPRM), the first step in a process that may lead to standards mandating GA’s transition to unleaded avgas. This action allows the public to comment on the current data being considered to develop standards to control lead emissions from piston-powered aircraft.
