Aviation gasoline (avgas) is a specialized fuel used to power piston engine aircraft. Emissions from the 190,000 U.S. general aviation airplanes operating on leaded fuel account for about 70% of the . A highly toxic substance that can result in an array of negative health effects in humans, lead is added to aviation gasoline to meet the performance and safety requirements of a sizable portion of the country . .
Yes, aviation fuel emerged as the largest source of lead emissions in the U.S. once lead was phased out of automotive gasoline beginning in the 1970s.
NEW YORK, NY Today, the Environmental Protection Agency (EPA) announced it will take the necessary steps to regulate lead pollution from aircrafts, the largest source of lead emissions in the country. While levels of airborne lead in the United States have declined 99 percent since 1980, piston engine aircraft that operate on leaded fuel are the largest remaining source of lead emissions into . The FAA's own environmental scientists confirm that jet fuel produces over eleven toxic chemicals. This briefing was for members of Congress and congressional staff only. At the national level, major sources of lead in the air are ore and metals processing and piston-engine aircraft operating on leaded aviation fuel.
Lead exposure can come from multiple sources, including leaded paint, contaminated soil, industrial emissions from battery recycling or metals . Lead is a toxic metal that was once used regularly in motor fuel, paint, ceramics, glassware, and other consumer products. While levels of airborne lead in the United States have declined 99 percent since 1980, piston-engine aircraft that operate on leaded fuel are the largest remaining source of lead emissions into . NEW YORK, NY Today, the Environmental Protection Agency (EPA) announced it will take the necessary steps to regulate lead pollution from aircrafts, the largest source of lead emissions in the country. Lead that is emitted into the air can be inhaled or can be ingested, primarily through contact with contaminated soils or other surfaces. This study also investigated the lead cleansing decay profiles of the aircraft engines under 100SF initial operations. WASHINGTON The U.S. Department of Transportation's Federal Aviation Administration (FAA) announced a new initiative that outlines how our country can safely eliminate the use of leaded aviation fuel by the end of 2030 without adversely affecting the existing piston-engine fleet. 4. Introduction . Airborne Lead and Aircraft Activity Data Collection at Airports: 46-105: 6. The Clean Air Act (CAA) is the United States' primary federal air quality law, intended to reduce and control air pollution nationwide.Initially enacted in 1963 and amended many times since, it is one of the United States' first and most influential modern environmental laws.. As with many other major U.S. federal environmental statutes, the Clean Air Act is administered by the U.S . References . What's being done? Significantly reducing lead emissions from gasoline-powered aircraft will require the leadership and strategic guidance of the Federal Aviation Administration (FAA) and a broad-based and sustained commitment by other government agencies and the nation's pilots, airport managers, aviation fuel and service suppliers, and aircraft manufacturers, says a new congressionally mandated report from . Air Quality Modeling and Emission Inventory Evaluation: 131-160: 8. EPA said it will propose an endangerment finding on leaded aviation gasoline by the end of 2022 and finalize the endangerment finding in 2023. CHANGES TO EXISTING FUELS AND THEIR SUPPLY A high-octane grade of avgas that contains less lead than 100LL, known as "100VLL" (very low lead), could be used by all piston-engine aircraft. The EPA opened a proceeding in 2010 to review the issue and in 2015 said it had . In 2006, the EPA received a petition asking for regulations of lead emissions from general aviation airplanes. Announced at the National Press Club in Washington, D.C., today, the Eliminate Aviation Gasoline Lead Emissions (EAGLE) initiative calls for an industry and government partnership to expand and accelerate the actions and policies necessary for a viable high-octane unleaded replacement for the current 100 octane low-lead aviation gasoline (100LL . While leaded gasoline was fully phased out in 1996 with the passage of the Clean Air Act, it still fuels a fleet of 170,000 piston-engine airplanes and helicopters. If the EPA issues regulations on lead emissions from piston-engine aircraft, the FAA would subsequently publish regulations that certify piston engine modifications, new piston engines that do not require leaded aviation fuel and regulate fuel components for aviation fuels.

The FAA has announced the launch of a new initiative designed to eliminate the use of leaded aviation fuel "without adversely affecting the existing piston-engine fleet" by the end of 2030. For mobile sources, the aircraft emissions are based on data from the U.S. Federal Aviation Administration for specific aircraft, often using state-supplied model inputs, and fuel consumption data. The phase-out of leaded gasoline significantly reduced vehicle emissions and lead levels in the environment, but it is still used in some aviation fuels and used or produced in a variety of industrial processes. One source of lead exposure that is often overlooked is aviation fuel. 4. The FAA will consider policies/programs to support unleaded fuel . The purpose of this study is to determine the amount of time required for engines to be free of lead emissions when first introduced to operation using 100SF. Application of the Refined Methodology Using Site-Specific Data: 106-130: 7. Lead emissions associated with GA and AT aircraft stem from the widespread use of one hundred octane low lead (100LL) avgas. Sources of lead emissions vary from one area to another. Airborne Lead and Aircraft Activity Data Collection at Airports: 46-105: 6. The FAA intends for most aircraft to use an unleaded replacement by 2018. Since aviation gasoline is now the largest remaining source of lead (Pb) emissions to the air in the United States, there is increased interest by regulatory agencies and the public in assessing the impacts on residents living in close proximity to these sources. This is referred to as an "endangerment finding." EPA officials said in a Jan. 12, 2022, announcement that the plan is to issue a proposed endangerment finding for piston-engine aircraft that run on leaded fuel in 2022 for public review . The National Academies of Sciences, Engineering, and Medicine released on Jan. 12 a congressionally mandated report on reducing lead emissions from small aircraftthe single largest lead emitter in the United States.

Emissions from other sources of Airborne Lead and Aircraft Activity Data Collection at Airports 46-105; 6. The gas that powers piston-engine aircraft for life-saving services like medivac may create public health risks by containing lead which is emitted from aircraft exhaust. The EPA has found that communities living near airports, children attending school near airports, and airplane pilots, student-trainees, and passengers are all at risk of exposure to lead emissions from these aircraft. If the EPA issues regulations on lead emissions from piston-engine aircraft, the FAA would subsequently publish regulations that certify piston engine modifications, new piston engines that do not require leaded aviation fuel, and regulate fuel components for aviation fuels. This lead additive helps boost fuel octane and prevents valve seat recession which can be a significant concern from a safety standpoint. Other sources are waste incinerators, utilities, and lead-acid battery manufacturers. . Development and Application of a Refined Methodology for Quantifying Aircraft-Related Lead Emissions: 28-45: 5.
