7 May 2, 2014 Sabine Pass Daily Max = 80 ppb With northerly winds through 12:00 noon, ozone at Sabine Pass tracked the upwind sites with hourly ozone levels equal to approximately 60 ppb As Sabine Pass winds shifted clockwise to become southerly, ozone levels rose Other sites, which remained in northerly flow continued to record approximately 60 ppb ozone Background ozone in the air transported from the north is estimated to be approximately 60 ppb; additional amount at Sabine Pass (approximately 20 ppb might be transport from Houston 1-Hour Ozone (ppb) :00 noon 3:00 p.m. Time 6

8 May 3, 2014: Daily Max Ozone = 79 ppb at Mauriceville; 77 ppb at Beaumont With westerly winds at 2:00 p.m. 1-hour ozone levels exceeded 75 ppb at every site except Sabine Pass and Port Arthur (SETRPC). 2:00 p.m. With a stronger southerly wind component at Sabine Pass, background ozone levels were approximately 65 ppb As the winds at other sites backed to become more southerly, ozone levels subsided to approximately 65 ppb 1-Hour Ozone (ppb) :00 p.m. Time 7

21 National Ambient Air Quality Standards The Clean Air Act (CAA) requires EPA to set National Ambient Air Quality Standards for pollutants considered harmful to public health and the environment. The Clean Air Act identifies two types of national ambient air quality standards. Primary standards provide public health protection, including protecting the health of "sensitive" populations such as asthmatics, children, and the elderly. Secondary standards provide public welfare protection, including protection against decreased visibility and damage to animals, crops, vegetation, and buildings. The CAA requires periodic review (5-year cycle) of the science upon which the standards are based and the standards themselves.

25 EPA Refinery Rule Fenceline Air Monitoring Presented to the SETRPC Air Quality Advisory Committee July 17, 2014 Albert Hendler, URS-Austin 1

26 Overview Part of broader rule affecting petroleum refineries Requires refineries to monitor benzene levels at ground level at multiple locations Specifies air sampling and analysis method Sample duration Trigger level for corrective actions 2

27 Sampling and Analysis Methods 325A and 325B Stainless steel tube packed with sorbent material 3.5 inches long ¼ inch outside diameter Packed with Carbograph 1 TD, Carbopack B, or Carbopack X 1 brass cap is replaced with the diffusive membrane when sampling 3

28 Sampler Deployment Mounted 5 6 feet above ground Protective hood to shield from rain 2-day to 2-week sampling period 4

29 Number and Placement of Samplers Depends on refinery size and shape of footprint Circular, triangular, rectangular refineries If less than 75 acres, place one sampler every 30-degrees along the perimeter (total of 12) If between 750 and 1500 acres, place one sampler every 20- degrees along the perimeter (total of 18) If greater than 1500 acres, place one sampler every 15 degrees along the perimeter (total of 24) Place additional samplers near known VOC sources Example: Midsize Rectangular Refinery 5

30 Reporting Rolling annual average Adjusted for background Initial demonstration of compliance 1 year after start of sampling; every 2 weeks, thereafter Action level is 9 µg/m3 (approximately 3 ppb) based on rolling annual average Root cause analysis must be initiated within 5 days after exceedance is measured 6
