REGULATORY ACTIVITY 12

OZONE n 1979 1 hr Ozone Standard (120 ppb) HGB Area must meet the standard by November 15, 2007. Very close to meeting standard. ¨ Controls: Billions $ spent on overall 80% NOx controls and HRVOC monitoring ¨ n 1997 8 hr Ozone Standard (85 ppb) ¨ ¨ n HGB Area must meet the standard by June 15, 2018. Very close to meeting the standard. Controls: A 25% reduction in the overall HRVOC cap 2008 8 hr Ozone Standard (75 ppb) Bush administration/EPA lowered standard to 75 ppb Obama administration/EPA immediately announced lowering of standard to between 60 – 70 ppb but eventually did not ¨ Texas non-attainment counties n Dallas/Ft Worth - Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, Tarrant, Hood, Wise n Houston – Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, Waller ¨ Controls: TCEQ is conducting modeling; Also looking at “Exceptional Events” and “International Emissions” contributions ¨ ¨ n Next Standard Next 5 year review cycle for the Standard is underway ¨ Current EPA timeline is to publish a draft proposal by year end 2013 and a final rule by Sept. 2014 ¨ Compliance deadline will depend on classification of Area: 2017 for Marginal, 2020 for Moderate, 2023 for Serious, and 2029 for Severe ¨ Proposals are for standard to be lowered to between 55 – 70 ppb ¨ 13

BOILER MACT n Final rule issued on March 21, 2011. Applicable to Boilers & Process Heaters n Reconsidered final published in Federal Register 1 -31 -2013. ¨ Existing sources – have 3 years from publication to comply. May request an additional year. ¨ New sources – comply Jan 31, 2013 or upon startup ¨ Many more subcategories of Boilers Requirements include CO / O 2 CEMS, performance tests, energy assessments, and controls if not meeting emission limits. ¨ Strict PM, HCL, Hg, CO and Dioxin limits for existing liquid and some fuel gas burning boilers ¨ Very strict limits for coal burning boilers ¨ 15

BOILER MACT n Boiler Energy Assessments ¨ ¨ ¨ ¨ ¨ A visual inspection of the boiler or process heater system. An evaluation of operating characteristics of the boiler or process heater systems, specifications of energy using systems, operating and maintenance procedures, and unusual operating constraints. An inventory of major energy use systems consuming energy from affected boilers and process heaters and which are under the control of the boiler/process heater owner/operator. A review of available architectural and engineering plans, facility operation and maintenance procedures and logs, and fuel usage. A review of the facility's energy management practices and provide recommendations for improvements consistent with the definition of energy management practices, if identified. A list of cost-effective energy conservation measures that are within the facility’s control. A list of the energy savings potential of the energy conservation measures identified. A comprehensive report detailing the ways to improve efficiency, the cost of specific improvements, benefits, and the time frame for recouping those investments. And a lot more requirements…………………. . 16

Other Rules n Risk and Technology Review (RTR rules) ¨ Polymers & Resin IV, Pesticides, Polyether Polyols (3 P) rule proposed Jan 9, 2012. Final rule by Jan 31, 2014 ¨ Polycarbonate, Acrylic & Modacrylic fibers, Polymers & Resins III proposal by Dec 11, 2013 ¨ Off-Site Waste & Recovery Operations (OSWRO) proposal by Dec 11, 2013 ¨ Ethylene MACT Section 114 request likely to be sent out in 4 Q 2013 ¨ OLD, MON, HON, NSPS review could be in 2014 n Flares ¨ EPA pursuing Consent Decrees ¨ EPA planning to propose Refinery rule on flares. 1 Q 2014. ¨ Will set precedent for the chemicals sector 17

Greenhouse Gas (GHG) n NSPS for GHGs for Utilities (new sources) – EPA to repropose by Sept 20, 2013 and finalize by June 1, 2014. ¨ NSPS for GHGs for Utilities (existing sources) – EPA to propose by June 1, 2014 and finalize by June 1, 2015. ¨ NSPS for GHGs for Refineries – after the Utilities ¨ n President’s Climate Action Plan (CAP) ¨ ¨ 17% reduction in carbon emissions from 2005 to 2020 Energy efficiency standards for industry n Mandatory Reporting Rule (MRR) CBI data – possible proposal 4 Q 2013 n TCEQ had two outstanding suits against EPA on GHGs – On July 26, 2013 the Court of Appeals sided with EPA 18

Impact to Utilities n On Aug 21, 2012 the Cross State Air Pollution Rule (CSAPR) vacated by the courts but CAIR remains in place. ¨ Goal is power sector emissions reductions ¨ However, was broadened to include chemical/refinery sector co-generation facilities ¨ EPA/NGOs successfully petitioned to Supreme Court n Mercury & Air Toxics Standard (MATS) n Cooling Tower Intake Rule ¨ Effects Utilities with large intake of cooling water from streams 19
