                Air Toxics
 Effects Screening Levels

 Benzene

 Butadiene

 Air Pollutant Watch List

                             3
        Effects Screening Levels
 New guidelines November 2006
   – External scientific peer review by panel of international
     experts
   – Two rounds of public comments


 Used in air permitting and for evaluating air
  monitoring data.

 Currently, 28 ESLs have been derived using the
  new process.

                  Benzene
 Risk-driver for Texas and U.S.
 Wide variety of emission sources
 Representative of other chemicals

 In 2008, no monitors in Harris County were
  above the long-term ESL for benzene
 All monitors in the Houston Region showed a
  decrease in average benzene concentration
  from 2005-2008
 87% of the monitors statewide showed a
  decrease in average benzene concentration
  from 2005-2008

                     Road Projects
 The City of Houston installed barriers to keep trucks from driving off
  Clinton Drive onto the dirt shoulders of the road.

 The City of Houston installed a traffic light at Clinton Drive and the
  Industrial Park East gate to control traffic at the intersection and
  completed a landscaping project along Clinton Drive.

 The TCEQ commissioners approved an SEP to pave the parking lot
  directly adjacent to the monitoring station.

 The Port of Houston Authority (PHA) reports widespread use of
  emulsified asphalt began October 1, 2007.

 Valero Asphalt paved its large work yard located across Clinton
  Drive to the southeast of the monitor.

                                                                           24
                Railroad Projects
 Port Terminal Rail Association (PTRA) and Union Pacific (UP) are
  operating newly refurbished switcher engines on the Clinton line.
   – UP currently has 52 new gensets in the Houston area.
   – UP has 13 locomotives being funded by TERP.

 60% of UP switcher engines operating in the area have anti-idling
  control.

 PTRA has stopped the steel loading activities on a dirt area to the
  south of the monitor.
     Regulated Industry Projects
 DuPont, a PHA tenant, has implemented new dust control best
  management practices at its fluorspar unloading and storage facility.

 Federal consent decrees are anticipated to result in an estimated
  33,900 tpy of SO2 reductions in the upper Texas Gulf Coast.
   – Valero Refining has already implemented control measures to
     reduce SO2 emissions by 3,500 tpy.
   – The Rhodia sulfuric acid plant will decrease its SO2 emissions by
     8,984 tpy from 2005 actual emissions by 2012.




                                                                     26

 Senate Bill 7 - Grandfathered Electric Generating
  Units
   – Resulted in emissions reductions of 102,436 tpy of NOX and
     SO2 from previously grandfathered electric generating units.
                                                                    27

                              -continued-

 The voluntary and mandatory permitting requirements for previously
  grandfathered facilities resulted in over 260,000 tons of reductions in
  actual emissions from these facilities either through the addition of
  controls or the shutdown of the facilities.
    – Senate Bill 766 - Voluntary Emission Reduction Permit or VERP
    – House Bill 2912 - Mandatory permitting of all grandfathered facilities.
