6. Description of content:  The EPA is proposing to ame nd the new source performance 
standards (NSPS) for stationary gas turbines  and stationary combustion turbines. These 
amendments are primarily in response to issu es raised by the regulated community. On 
6 July 2006, the EPA promulgated amendments to  the new source performance standards for 
stationary combustion turbines. On 5 Septem ber 2006, the Utility Air Regulatory Group filed 
a petition for reconsideration of certain aspect s of the promulgated standards. The EPA is 
proposing to amend specific  provisions in the NSPS to resolv e issues and questions raised by 
the petition for reconsideration, and to address ot her technical and editorial  issues. In addition, 
this proposed rule would amend the location a nd wording of existing paragraphs for clarity. 
The proposed amendments would increase th e environmental benefits of the existing 
requirements because the emis sion standards would apply at  all times. The proposed 
amendments would also promote efficiency by recognizing the environmental benefit of 
combined heat and power and the benefici al use of low energy content gases.
