Russell Price P.E., Marketing Manager for Stanley Consultants Inc., presented a structured five-step approach for boiler operator to define their available options and create a MACT compliance plan. In summary, the plan would define goals, gather data, evaluate compliance alternatives of each of the five regulated pollutants then develop composite solutions and evaluate them based on life cycle cost.

Ed Schindler, Vice President of Utility Sales at Combustion Components Associates, Inc., presented various strategies for reducing CO in existing boilers including CFD, burner tuning, burner modification, adjusting burners to get good fuel and air balance, replacing worn parts, upgrading atomizers and fuel injectors and, as a last resort, installing a CO catalyst. He gave examples of the results that can be obtained with various sized boilers using one or more of these strategies and stated that almost every boiler could achieve compliance with the MACT limits by utilizing one or more of these strategies.

Ajay Kasarabada, an Air Permitting Manager in Black & Veatch Energy Division's Environmental Management Services Section, and Diane Fischer, Manager of Business Development for Air Quality Control Projects for Black & Veatch’s Power Generation Services, described a method for avoiding the need to comply with the Boiler MACT – “the non-solid fuel pathway”. They presented a methodology by which boiler operators can evaluate the technical and economic issues related to converting boilers to operate on “Gas 1” or “Other Gas 1” as defined by the EPA or decommissioning solid fueled boilers and installing new gas-fired boilers or gas turbines. Gas 1 units, Other Gas 1 units and combustion turbines do not have to meet Boiler MACT emission limits. Diane’s portion of the presentation focused on the benefits of considering co-generation and provided a detailed methodology for evaluating this alternative. They indicated that Black and Veatch is involved in studying these alternatives for a number of boiler operators but they have not yet reached any firm conclusions. However, now that the Boiler MACT has been issued, they are moving forward rapidly.

Enhanced Mercury Oxidization (EMO) by Steve Baloga, Shaw - Hot Topic Hour March 10, 2011
Steve Baloga P.E., a Senior Environmental Consultant at Shaw Environmental & Infrastructure, described a process for economically reducing mercury emissions from boilers combusting bituminous or sub-bituminous coal. EMO™, a liquid brominated oxidant, is injected into the gas stream at the exit of the boiler or economizer to convert elemental mercury into the oxidized version that is more readily captured by existing control equipment. With very low injection rates, this can be an effective low cost solution to achieve the new lower limits required by the MACT. He presented data on several boiler trials that demonstrate the viability of this low cost approach.

Boiler MACT Rule by Brian Higgins, Nalco Mobotec - Hot Topic Hour March 10, 2011
Brian Higgins PhD., Vice-president of Technology for Nalco Mobotec, gave a good summary of the new MACT rule and potential compliance solutions for the five regulated pollutants - PM, CO, HCl, Hg, and dioxin/furan. Brian described the potential for boiler operators to control just HCl to become a “Synthetic Area Source” and effectively then need to only comply with the far less onerous Area Source regulations. He also discussed fuel categories, the RCRA definitions of solid wastes and CISWI MACT overlap.

Mack McGuffey practices environmental law as an associate in Troutman Sanders' Atlanta office and specializes in regulatory compliance under the Clean Air Act. Last November at the last webinar on the IBMACT before the rule was published, he gave a very good presentation on the status of the ruling and potential future litigation. Now that the rule is out, Mack was able to provide an overview of the MACT program, explain how EPA's final Industrial Boiler MACT standards differ from the ones it originally proposed, and describe some of the legal issues associated with EPA's final rule. A key point made was that although EPA indicated that because of concerns over the legality of the significant changes between proposed rule and final rule, EPA is taking comment on the final rule, any delay in or stay of the deadline for compliance is very unlikely. He also emphasized that affected boiler operators must do whatever is necessary to comply with the new emission limits. Just installing additional control equipment will not be sufficient.

Industrial Boiler MACT - Impact and Control Options - Webinar March 10, 2011
On February 23, 2011 the U.S. EPA issued “Sensible Standards” for Boilers and Certain Incinerators that cut the cost of implementation by about 50 percent from an earlier proposal issued last year. Because the final standards significantly differ from the proposals, EPA believes further public review is required. Therefore, EPA will reconsider the final standards under a Clean Air Act process that allows the agency to seek additional public review and comment to ensure full transparency. EPA's reconsideration will cover the emissions standards for large and small boilers and for solid waste incinerators.
