            Our Measuring Process


   VOC samples are taken using EPA-approved
    methods and equipment
       One sample every sixth day for a 24-hour
        period at each monitoring site
       Approximately 10,000 VOC samples collected
        by HRM in last 25 years with more than 1
        million VOC results reported
   Sampling methods are routinely audited using EPA
    audit methods

              Our Analysis Process

   Upon collecting data from monitoring stations, we:
       Compare to EPA’s National Ambient Air Quality
        Standards (NAAQS)
       Compare to known benchmark concentrations
       Compare with computer modeling results
       Analyze trends
       Compare with data from other cities
       All HRM measurement results are accessible to
        members via a web portal

             Sharing Information
   An active process with our member
    companies, agencies and
    communities
       Monthly Technical Advisory Committee
        meetings – includes member
        companies, TCEQ, Harris County and
        City of Houston

                    What We Know:
         Putting Houston’s Air Quality in Context
   Houston’s air meets 5 of 6 of the federal NAAQS, the exception
    being ground-level ozone

        Houston air compares favorably with other cities when looking
         at all of the NAAQS

        According to EPA data, Las Vegas, Philadelphia, Pittsburgh,
         Phoenix, Los Angeles, New York, Sacramento, and Salt Lake
         City all fail to meet two or more of the NAAQS

   On average an 80 percent reduction in ambient concentration of
    key VOCs (BTEX) in the past 18 years

   Industry has spent $4-6 billion in Houston from 2002-2012 to
    improve air quality -- on top of substantial investment in the 1990s

     Using TCEQ Air Monitoring Comparison
     Values (AMCVs) As Air Quality Indicator
   TCEQ implemented use of the term “air monitoring comparison values”
    (AMCVs) to evaluate air monitoring data. AMCVs are chemical-specific air
    concentrations set to protect human health and welfare

   Exposure to an air concentration at or below the AMCV is not likely to
    cause adverse health effects

   AMCVs are a collective term that refers to all values used by TCEQ to
    review ambient air monitoring data

   The short-term AMCV, based on acute exposure health and welfare data, is
    compared to monitored concentrations ranging from instantaneous to up
    to one hour. The long-term AMCV, based on chronic health and welfare
    data, is used to evaluate annual averaged monitored concentrations or
    annual concentrations averaged over multiple years (if available)

                                                                               21
                 What We Know:
     Monitoring Data Indicate Good Air Quality

   A comparison of the 2012 monitored ambient
    concentrations of a list of common urban air pollutants
    to the AMCVs generally indicates very good air quality
    in the greater Houston area.

   The 2012 annual average benzene concentration at all
    monitoring sites were below the AMCV.

           Our Mission Going Forward:
       Maintaining and Improving Air Quality

   Provide data to member companies to enable them to meet state
    and federal air standards

   Assist TCEQ in air monitoring to meet NAAQS
      Monitors must show progress toward meeting NAAQS for
       ground-level ozone and confirm attainment
      Houston area targeting an 80 percent reduction in NOx and
       substantial reduction in HRVOCs

   Use HRM data as input to rigorous permitting process to identify
    air control improvements in projects

   Communicate with neighbors about our improving air quality and
    address their questions

     What This Means for Air Quality

   Houston’s air quality has dramatically improved and
    will continue to improve

   Houston’s air quality is monitored and analyzed using
    the most thorough network in the country

   HRM and its members recognize our responsibility
    and have made significant investments as part of our
    commitment – but we can and will do better.
