Compliance Issues for the Utility MACT as Proposed by Carl Weilert - Burns & McDonnell - Hot Topic Hour October 4, 2011

Carl V. Weilert, Principal Process Engineer at Burns & McDonnell, discussed “The Good, the Bad and the Ugly” aspects of the proposed rule. On the positive side, he noted that the proposed rule allows for averaging among multiple units at a facility. On the negative side, he discussed why the test methods and processes for measuring total particulate matter were unreliable and questioned EPA’s assumption that dry sorbent injection (DSI) could be used to achieve compliance with the HCl limits. He also pointed out that the MACT limits for new units were too low and could effectively block any new fossil-fuel projects.

The Utility MACT - How did EPA arrive at the Floors/Limits for Existing Sources and Can we Expect Changes by Kasi Dubbs - Trinity Consultants - Hot Topic Hour October 4, 2011

Kasi Dubbs, Managing Consultant at Trinity Consultants, summarized the methods and processes used by EPA to set emission limits for the Utility MACT rule. Her presentation was particularly effective in showing the impact of EPA’s “Franken-plant” approach to setting the MACT floor. For example, of the top 20 performing units for PM, only one unit was also on the list of top 20 performing units for total suspended metals. Similarly, of the top 20 units for SO2, only one unit was also on the list of the top 20 units for HCl. She also identified other issues associated with EPA’s method for defining the “top performing 12%” of units in establishing the MACT floor.

The Proposed Utility MACT Rule, by Brian Higgins - Nalco Mobotec -Hot Topic Hour October 4, 2011

Brian Higgins, Vice-President for Technology at Nalco Mobotec, Inc., discussed compliance strategies for the proposed rule. In particular, he noted the difficulty of using particulate matter CEMS (which measures only filterable PM) to demonstrate compliance with a total particulate matter standard. He also discussed issues associated with the ash from DSI systems used to achieve compliance with the HCl limit.
