### August 16,2012 Statement of Fred Thompson Associate Director for Sector Policies and Programs Division U.S. Environmental Protection Agency (EPA) National Emission Standards for Hazardous Air Pollutants for the Portland Cement Manufacturing Industry and Standards of Performance for Portland Cement Plants Arlington, Texas Good morning and thank you for attending this public hearing . My name is Fred Thompson, and I am the Associate Director for the Sector Policies and Programs Division in the U.S . Environmental Protection Agency's Office ofAir Quality Planning and Standards, based in Research Triangle Park, North Carolina. I will be chairing today's hearing . Joining me on the panel are : Sharon Nizich and Keith Barnett, also with the Office ofAir Quality Planning and Standards, and Maria Martinez and Ruben Casso with EPA's Region 6 office . We are here today to listen to your comments on all aspects ofEPA ' s proposed amendments to the

' 'National Emission Standards for Hazardous Air Pollutants for the Portland Cement Manufacturing Industry and Standards ofPerformance for Portland Cement Plants." EPA published the proposed amendments in the Federal Register on July 18 , 2012.

The proposed amendments would retain several key air toxics emission limits in the 20I 0 rules , including limits for mercury , hydrochloric acid and total hydrocarbons. These limits will dramatically cut emissions ofthese harmful pollutants from cement production. The proposed amendments would adjust the way cement kilns monitor particulate matter (PM) emissions and would make changes to the PM emission limit that would be necessary with the monitoring change.2 EPA proposed these changes based on new technical information about the capabilities ofcontinuous emission monitors for PM . Note that kiln s would still be required to continuously monitor PM emissions under the proposed amendments.

The proposal would also extend the compliance date for existing kilns under the air toxics standard by two years from September 2013 to September 2015. EPA is seeking comment on this proposed compliance date extension.

In addition , the propo sed amendments would revise the open clinker pile standards from the 2010 final rule by allowing facilities to choose from a list of work practices to control fugitive emissions; and would change an alternative emission limit for organic air toxics that kilns may meet in lieu ofmeeting a limit for total hyd rocarbons . I would like to draw your attention to the deadline for submitting written comments on the proposal. That deadline is tomorrow- August 17 , 2012. However, we will hold this hearing record open for an additional 30 days to allow people to submit supplemental or rebuttal information that is related to te stimony at



# . today ' s hearing. You may submit this type of information until September 17 , 2012. There are handouts in the registration area with instructions for submitting written comments. EPA will carefully consider your comments from today 's hearing along with written comments as we move forward to complete t he final rule. Under a draft settlement agreement, EPA would take final action on this proposal by December 20, 20 12.3 We will prepare a written transcript oftoday ' s hearing. The transcript will be available as part ofthe official record for this rule . Let me mention briefly two other air emissions standards that apply to Portland cement manufacturing that are not the subject oftoday ' s hearing . The first standards , issued under a separate section ofthe Clean Air Act, cover cement kilns that burn nonhazardous waste . This is known as the Commercial and Industrial Solid Waste Incinerator rule, or CISWI rule. This rule is currently under reconsideration . Amendments to the CISWI rule were proposed on December 23 , 2011. The final rule is undergoing interagency review . The second set of standards regulates air toxics emissions from cement kilns that burn hazardous waste. These standards, issued in 2005 , are known as the Hazardous Waste Combustor National Emissions Standards for Hazardous Air Pollutants . The proposed standards we are taking comment on today apply only to cement kilns that do not burn waste of any type, either commercial or hazardous waste. Now, let me describe the procedures for today's hearing . I will call the scheduled speakers to the table in pairs . When it is your turn to speak, please state your name and your affiliation before you begin your testimony . It would help our court reporter if you also spell your name. ln order to be fair to everyone , we will limit your testimony to 5 minutes each .
