    EPA Proposes NOx Emission Standards for Aircraft Gas Turbine Engines

EPA is proposing to adopt emission standards and related provisions for aircraft gas turbine engines with rated thrusts greater than 26.7 kilonewtons. These engines are used primarily on commercial passenger and freight aircraft. The proposed requirements were either previously adopted by the International Civil Aviation Organization (ICAO), or agreed on at ICAO’s Committee on Aviation Environmental Protection (CAEP) in 2010. Included in the proposal are two new tiers of more stringent emission standards for oxides of nitrogen (NOx). These are referred to as Tier 6 (or CAEP/6) standards and Tier 8 (or CAEP/8) standards. The proposed standards would become effective for newly-manufactured aircraft engines beginning in 2013.

EPA Announces Next Steps for Greenhouse Gas Emissions Reporting Program

WASHINGTON – The U.S. Environmental Protection Agency is announcing that its Greenhouse Gas (GHG) Reporting Program has recently completed extensive work to develop GHG data reporting requirements for a wide range of different industries in response to Congressional mandates. This program will provide Congress, stakeholder groups and the public with information about these emissions while helping businesses identify cost effective ways to reduce emissions in the future.

To ensure that the requirements are practical and understandable to the thousands of companies already registered to report under the program, the agency is in the process of finalizing a user friendly online electronic reporting platform.

Following conversations with industry and others, and in the interest of providing high quality data to the public this year,  EPA is extending this year’s reporting deadline – originally March 31 – and plans to have the final uploading tool available this summer, with the data scheduled to be published later this year.  This extension will allow EPA to further test the system that facilities will use to submit data and give industry the opportunity to test the tool, provide feedback, and have sufficient time to become familiar with the tool prior to reporting.  The agency will provide more detail on these intended changes in the coming weeks and will ensure that this reporting extension is in effect before the original reporting deadline of March 31, 2011.

EPA’s greenhouse gas reporting program, launched in October 2009, requires the reporting of GHG emissions data from large emission sources and fuel suppliers across a range of industry sectors. This program will provide data that will help industries find ways to be more efficient and save money.
