On Monday, July 8, APPA will hold a webinar, "PM 2.5 Modeling: New Challenges to Air Permits" from 2 to 3:30 p.m., Eastern time. 

The U. S. Environmental Protection Agency has made several changes—many within the last six months—to the way fine particulate matter (PM 2.5) is addressed in permitting. These changes will make it more challenging to permit new or modified sources at power plants, including gas-fired turbines with no oil backup. Changes include the EPA tightening the PM 2.5 air quality standard; a court decision making it more difficult to use previously relied upon screening techniques in permitting; and lengthy guidance on how to do PM 2.5 air dispersion modeling. 

A number of public power utilities are making decisions regarding retrofit and compliance with EGU MACT or opting to "scrape" and rebuild a new natural gas (usually combined-cycle) gas plants. The permitting application process has been more complicated than expected due to the PM 2.5 screening techniques. Whether you are permitting a new combined-cycle natural gas plant or making changes for regional haze purposes, your power plant will need effective PM modeling. In this webinar,  William Jones with Zephyr Environmental Corp. will cover these issues and other permitting challenges related to dispersion modeling requirements and how they could impact public power utilities. 
Then, on Wednesday, July 10 from 2-3:30 p.m., Eastern time, APPA will hold a webinar on "Regional Transmission Organizations: RTO 201." This webinar will delve into the details of the RTO-operated mandatory locational capacity markets, including how they function, why they were created and whether they have achieved their goals. The speaker will discuss recent rule changes in in the Eastern RTOs and how these changes may impede public power's self-supply abilities.

Dr. Ken Rose, an economist with expertise in federal and state electricity regulations, will be the speaker for this webinar.

This is the second in a series of two webinars on RTOs. A recording of the first webinar, RTO 101, which was held on June 26, is available for purchase through the APPA Product Store.
Each webinar is worth 0.2 continuing education units, 1.5 professional development hours and 1.5 continuing professional education credits.
