Navajo Generating Station

Between 2010 and 2013 EN3 Professionals facilitated a series of outreach efforts involving many parties having an interest in the reduction of emissions from the Navajo Generating Station in Page, Arizona as required by the Clean Air Act. Through a series of stakeholder meetings in 2011, the plant owners sought to develop an agreement among interested parties that would be considered for a Best Available Retrofit Technology (BART) determination by USEPA, and as a basis for other potential actions by plant owners, public agencies and interested parties. Nitrogen oxides, particulate matter, and hazardous air pollutant emissions from NGS Units 1, 2, & 3 were to be addressed. Additionally, research on this complex topic was begun by the National Renewable Energy Laboratory. Discussions regarding the plant’s emissions control options have been ongoing through the duration of this BART determination process. In January 2013 USEPA issued a proposed final BART determination, which included a request for additional proposals as alternatives for BART. In response, a Technical Work Group consisting of some of the NGS stakeholders worked collaboratively to address this EPA request and submitted an agreement to EPA in late July 2013 as an alternative for consideration under this BART determination. The deadline for public comments is October 4.

To review the entire Technical Work Group agreement as submitted to EPA, see below.
