ERAU Is Pushing the Envelope Yet Again!

Friday, May 16th, 2014

by Diana Wasiuk

Graduates of my alma mater, Embry-Riddle Aeronautical University (ERAU), have a reputation for ‘pushing the envelope’ in more than one way… The Small Aircraft Transportation System (SATS) was one of those forward thinking ideas that only a bunch of aviation nuts could come up with and commit to with boundless enthusiasm. And boy did we ever!  Here is an article on another example of ERAU pushing for innovation: developing electric propulsion systems to reduce noise and emissions:

Report from ACI-NA Environmental Affairs Conference

Tuesday, May 21st, 2013

by Mary Ellen Eagan

ACI-NA’s Annual Environmental Affairs Conference was held this week in Halifax, NS.  The agenda was robust and featured several innovations, including the use of TurningPoint polling technology and providing the ability for several travel-challenged speakers to participate remotely via webinar.   I had the privilege of participating directly in three sessions:

  • Is Perception Reality?  Human Health Studies & Risk Management – A Hypothetical Airport Case Study:  In this session, we conducted a “table-top” exercise of how airports respond to concerns about potential for health issues resulting from airport (noise, emissions, etc).  This interactive panel role-played an airport staff meeting – including a surprise visit by the concerned citizen, Mr. Bob Jones from Erewhon, YZ.
  • Technology Tools for Environmental Management:  this session provided an overview of GIS and other tools that are being to deployed to cost-effectively manage airport environmental issues.  My presentation, “There’s an app for that! Tools and technology for addressing aircraft noise issues” provided an overview of recent advances in noise monitoring.
  • Noise and NextGen:  I provided an update on the work of the RTCA’s CATEX 2 Working Group, which has finalized its recommendation to the NextGen Advisory Committee (it will be presented at the NAC on June 4).

Looking forward to the next Environmental Affairs Seminar in San Jose, CA at the ACI-NA Annual Conference.

EPA Delays Greenhouse Gas Stationary Permits Until 2011

Monday, April 5th, 2010

by Phil DeVita

On March 29, 2010, the EPA issued a final decision to delay the greenhouse gas permitting requirements for stationary sources until January 2011.  The delay allows facilities and state agencies to adequately prepare to cut GHG emissions.  This announcement is a first step to what the agency called a “phasing in” approach to addressing GHG emissions.  The phased approach will require large stationary sources that already must apply for Clean Air Act (CAA) permits to address their GHG emissions in their permit applications in the first half of 2011.  Other large sources will need to address their emissions in the latter half of 2011.  The permits will require sources to prove they are using the best available control technology (BACT) to reduce emissions.  Typical large sources include power plants, factories, and refineries.  The emission threshold requiring a GHG permit has not been finalized, however, the EPA expects that the threshold will be higher than the 25,000 ton limit originally proposed.  

EPA is also expected to announce on April 1st final GHG standards for cars and trucks.  These standards will not take effect until January, 2011 for the 2012-2016 model years. 

This announcement is part of EPA’s response to comply with the Supreme Court’s decision three years ago in the Massachusetts v. EPA case.  In the landmark decision, the court ruled that greenhouse gases are subject to regulation under the Clean Air Act.  In December of 2009, EPA determined that GHG pollution endangers the public health and welfare, as such, it believes it is obligated under the CAA to issue greenhouse gas emissions standards for motor vehicles.

Senator Lisa Murkowski of Alaska recently introduced a “disapproval resolution” that would block EPA from moving ahead on these issues.  The disapproval resolution is currently in committee and there is no timeline for a potential vote.  On the other front, the “cap and trade” bill which would impose steadily declining limits of GHG emissions from large industrial sources has passed the House of Representatives and is stalled in the Senate.  Many Midwest lawmakers, who’s districts are dependant on energy produced by coal, are wary of the implications the bill will have on electricity costs.  After the healthcare debate, many believe the time may not be right for another contentious debate on cap and trade. 

Stay tuned.
