As mentioned in earlier posts, “Environmental Advocacy Group Sues EPA to Regulate Emissions from Aviation Gasoline” and “EPA Sets Its Regulatory Cross Hairs on Leaded Aviation Fuel,” leaded aviation gasoline, or avgas, is a concern in the general aviation industry. Lately, the issue has garnered more attention as the Environmental Protection Agency (“EPA”) examines possible regulation of lead emissions from aircrafts.
Not much progress has been made to develop an alternative fuel to 100 octane low-lead (100LL), mainly due to the ready availability of the current fuel, a lack of regulation, and the technical infeasibility of developing a single “drop-in” alternative fuel that can be deployed across the entire industry. Aviation industry leaders realize, however, that steps forward must be taken if the industry wants to avoid future regulation.
Last week, the Unleaded Avgas Transition Aviation Rulemaking Committee (“UAT ARC”) released a final report detailing how to incentivize and facilitate the certification of an alternative aviation fuel to 100LL. Formed in 2011 by the Federal Aviation Administration (“FAA”); the ARC is a joint industry-government task force with a goal of advancing unleaded aviation gasoline by 2018. Members on the industry side include the Aircraft Owners and Pilots Association (“AOPA”), the Experimental Aircraft Association (“EAA”), the General Aviation Manufacturers Association (“GAMA”), the National Air Transportation Association (“NATA”), and the National Business Aviation Association (“NBAA”). The government stakeholders are FAA and EPA.
Collaboratively, this task force has worked to ensure the continued availability of aviation gasoline in an unleaded form. According to FAA’s press release, the ARC’s report outlines five key recommendations. These are:
- Implement a fuel development roadmap for avgas readiness levels that identifies milestones in the aviation gasoline development process.
- Establish centralized testing of candidate unleaded fuels which would generate standardized qualification and certification data.
- Establish a solicitation and selection process for candidate unleaded aviation gasolines for the centralized testing program.
- Establish a centralized certification office to support unleaded aviation gasoline projects.
- Establish a collaborative industry- government initiative called the Piston Aviation Fuels Initiative (PAFI) to implement the UAT ARC recommendations to facilitate the development and deployment of an unleaded avgas with the least impact on the existing piston-engine aircraft fleet.
The participation of EPA is essential to the success of this framework. EPA has been pressured with litigation to promulgate regulations to eliminate or significantly reduce lead emissions. If FAA and industry groups can address the issues and recommendations outlined in the final report in a timely fashion and in a manner that is amenable to both the environment and industry, EPA will not have to take steps to regulate.
