In , Swift Fuels LLC was formed to bring in oil and gas industry experience, scale up production and bring the fuel to market. By November , the company had built its pilot plant and received approval to produce fuel in it.

This fuel is made by blending existing refinery products and yields detonation margins comparable to LL. The new fuel is slightly more dense than LL, but has a 3. GUL is compatible with LL and can be mixed with it in aircraft tanks for use.

The production economics of this new fuel have not been confirmed but it is anticipated that it will cost at least as much as LL. In demonstrations held in July , GUL performed better than LL that just meets the minimum specification and performed as well as average production LL. In December Shell Oil announced that they had developed an unleaded octane fuel and will submit it for FAA testing with certification expected within two to three years.

No information has yet been published in its performance, producibility or price. Industry analysts have indicated that it will likely cost as much as or more than existing LL. TEL found in leaded avgas and its combustion products are potent neurotoxins that have been shown in scientific research to interfere with brain development in children.

The United States Environmental Protection Agency EPA has noted that exposure to even very low levels of lead contamination has been conclusively linked to loss of IQ in children's brain function tests, thus providing a high degree of motivation to eliminate lead and its compounds from the environment.

While lead concentrations in the air have declined, scientific studies have demonstrated that children's neurological development is harmed by much lower levels of lead exposure than previously understood. Low level lead exposure has been clearly linked to loss of IQ in performance testing.

Even an average IQ loss of 1—2 points in children has a meaningful impact for the nation as a whole, as it would result in an increase in children classified as mentally challenged, as well as a proportional decrease in the number of children considered "gifted". On November 16, , the environmental group Friends of the Earth formally petitioned the EPA, asking them to regulate leaded avgas.

The EPA responded with a notice of petition for rulemaking. Friends of the Earth has filed a petition with EPA, requesting that EPA find pursuant to section of the Clean Air Act that lead emissions from general aviation aircraft cause or contribute to air pollution that may reasonably be anticipated to endanger public health or welfare and that EPA propose emissions standards for lead from general aviation aircraft.

Alternatively, Friends of the Earth requests that EPA commence a study and investigation of the health and environmental impacts of lead emissions from general aviation aircraft, if EPA believes that insufficient information exists to make such a finding. The petition submitted by Friends of the Earth explains their view that lead emissions from general aviation aircraft endanger the public health and welfare, creating a duty for the EPA to propose emission standards.

The public comment period on this petition closed on March 17, Under a federal court order to set a new standard by October 15, , the EPA cut the acceptable limits for atmospheric lead from the previous standard of 1. This was the first change to the standard since and represents Kenneth Copeland Jet Planes Co Ltd an order of magnitude reduction over previous levels. The new standard requires the 16, remaining USA sources of lead, which include lead smelting, airplane fuels, military installations, mining and metal smelting, iron and steel manufacturing, industrial boilers and process heaters, hazardous waste incineration, and production of batteries, to reduce their emissions by October The EPA's own studies have shown that to prevent a measurable decrease in IQ for children deemed most vulnerable, the standard needs to be set much lower, to 0.

The EPA identified avgas as one of the most "significant sources of lead". At an EPA public consultation held in June on the new standards, Andy Cebula, the Aircraft Owners and Pilots Association 's executive vice president of government affairs, stated that general aviation plays a valuable role Jet Planes Colouring Pages Names in the USA economy and any changes in lead standards that would change the current composition of avgas would have a "direct impact on the safety of flight and the very future of light aircraft in this country".

They cited that the aviation sector employs more than 1. AOPA interprets the new regulations as not affecting general aviation as they are currently written. The EPA indicated: "This action will describe the lead inventory related to use of leaded avgas, air quality and exposure information, additional information the Agency is collecting related to the impact of lead emissions from piston-engine aircraft on air quality and will request comments on this information.

Despite assertions in the media that leaded avgas will be eliminated in the US by at the latest date, the EPA confirmed in July that there is no phase-out date and that setting one would be an FAA responsibility as the EPA has no authority over avgas. The FAA administrator stated that regulating lead in avgas is an EPA responsibility, resulting in widespread criticism of both organizations for causing confusion and delaying solutions. Avgas is occasionally used in amateur auto racing cars as its octane rating is higher than automotive gasoline thus allowing the engines to run at higher compression ratios.
