6 Page 6 of 13 AOP Permit Fees $0 Spokane Regional Clean Air Agency Air Quality Report August 2013 Smoke from wildfires on the east slopes of the Cascades in Washington, in central Idaho and in central California near Yosemite National Park affected air quality in August. The Air Quality Index (AQI) was in the moderate range on August 1 because of smoke from wildfires on the east slopes of the Cascades (Figure 1). Figure 1: Air Quality Index (AQI) values for August 2013 A change in the weather pattern and rain on August 2 helped clear the smoke out of the Spokane area. The AQI rose into the moderate or near-moderate range again for the period of August 6 through 15. A high pressure ridge inhibited atmospheric ventilation, allowing ground-level ozone and fine particulate matter (PM 2.5 ) concentrations to build. Southerly atmospheric flow carried smoke from wildfires in central California and central Idaho into the Inland Northwest until the air flow shifted to westerly on August 16. Another high pressure ridge was over the region during the period of August 21 through 25, inhibiting atmospheric ventilation and allowing fine particulate matter. Carbon monoxide remained well within the good range of the AQI throughout the month. See Appendix 1 of this report for information about federal air quality standards or Appendix 2 for a description of the AQI. The particulate matter data used to determine the AQI and for other day-to-day operations are obtained using a network of automated particulate matter monitors consisting of Tapered Element Oscillating Microbalances (TEOM) and nephelometers. Daily mass concentrations of PM 2.5 monitored in August throughout the network are shown in Figure 2.

7 Page 7 of 13 Figure 2: PM 2.5 multi-station time series for August The August daily air quality data for all monitoring stations in the Spokane region are provided in Appendix 3. Current and historical air quality data can be obtained electronically from Ecology via their air monitoring data website, Tables 1 and 2 contain the maximum AQI values for each pollutant for the month and for the year to date. Table 3 summarizes the year to date daily AQIs by category and compares them to last year s AQIs. Table 1: Maximum AQI values and pollutant concentrations for this reporting period Pollutant AQI/Concentration Location Date CO 10/0.9 ppm (8 hour) Spokane, 3 rd & Washington 8/2, 8/9, 8/28 and 8/29 O 3 88/0.071 ppm (8 hour) Spokane, Augusta & Fiske 8/12 PM 10 51/56 µg/m 3 Cheney, Turnbull NWR 8/10 PM /18.9 µg/m 3 Spokane, Augusta & Fiske 8/23 Table 2: Maximum AQI values and pollutant concentrations to date this year Pollutant AQI/Concentration Location Date CO 27/2.4 ppm (8 hour) Spokane, 3rd & Washington 1/25 O 3 88/0.071 ppm (8 hour) Spokane, Augusta & Fiske 8/12 PM10 58/69 µg/m3 Spokane, Augusta & Fiske 2/15 PM /36.6 µg/m3 Spokane Valley, E.

Otherwise the numbers here depict the number of days in each category as they were originally reported. Category Number of Days This Year Last Year to Date Good (0-50) 190 (197) 223 Moderate (51-100) 52 (45) 19 Unhealthy for Sensitive Groups ( ) 1 (1) 1 Unhealthy ( ) 0 0 Very Unhealthy ( ) 0 0 Hazardous (>300) 0 0 Wind speed and direction are measured at the SRCAA s office, located near the intersection of Mission Ave and Greene St in Spokane. In the Spokane area, stronger southerly (S) to southwesterly (SW) surface winds are associated with more active weather regimes and storm systems promote better air quality than light easterly (E) to northeasterly (NE) winds, which are often terrain-driven at the SRCAA location and occur along with poor atmospheric ventilation (Figures 3 and 4). Figure 3: The wind rose depicts the variation of hourly average wind speed (mph) with the direction from which the wind was blowing in August.

9 Page 9 of 13 Figure 4: The PM 2.5 pollution rose depicts the variation of hourly average PM 2.5 from which the wind was blowing in August. 3 ) with the direction Ground-level ozone (O 3 ), a component of smog, is formed when nitrogen oxides and volatile organic compounds chemically react in the presence of sunlight. It is measured in units of parts per million (ppm) in ambient air. Ozone is a strong oxidizer and can damage lung tissue, thereby impairing respiratory function. The main sources of ozone precursors are motor vehicle emissions and refueling, gasoline storage and transport, paints, solvents and industry. Ground-level ozone reached the moderate category of the Air Quality Index (AQI) on five days (Figure 1). The maximum 8-hour running average was ppm (August 12; Figure 5). Eight hour average ozone concentrations in the range 0.06 to ppm are considered moderate air quality by the AQI. AQI moderate levels of ground-level ozone were measured mostly during warmer periods with high atmospheric pressure over the region (Figure 5). Figure 5: Eight hour maximum ozone concentrations for the Spokane region in August. Daily maximum temperatures are also shown. Daily maximum temperature can be used as a surrogate for solar radiation (ozone is formed through a photochemical reaction) for determining potential ozone maximum concentrations. The threshold for the moderate category for the AQI for ozone is 0.06 ppm averaged over eight hours. An ozone measurement above ppm, averaged over eight hours, is the threshold value for the federal ozone standard. It is not a violation of the standard to exceed this level on a given day because determination of attainment status is based on averaging data over a period of years. See Appendix 1 for more detailed information about attainment of federal air quality standards.

10 Page 10 of 13 Nitrogen oxides monitored at the Spokane Augusta Ave station remained low through the month (Figure 6). Figure 6: One hour maximum concentrations of nitrogen oxides for Spokane Augusta Ave monitoring station in August. The federal standard daily 1-hour maximum for nitrogen dioxide (NO 2 ) is 100 ppb. The NAAQS does not set limits on the other air pollutants shown here.

11 Page 11 of 13 Appendix 1 National Ambient Air Quality Standards The Clean Air Act requires EPA to set National Ambient Air Quality Standards (NAAQS) for six common air pollutants, carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO 2 ), particulate matter (PM 10 and PM 2.5 ), groundlevel ozone (O 3 ) and sulfur dioxide (SO 2 ; Table A-1). These are known as criteria pollutants because the US EPA established regulatory limits to concentrations in ambient air using human health or environmentally based criteria. Carbon monoxide, particulate matter and ozone are monitored in Spokane County by the Spokane Regional Clean Air Agency (SRCAA) and the Washington State Department of Ecology (Ecology). Table A-1: National Ambient Air Quality Standards Primary Standards Secondary Standards Pollutant Level Averaging Time Level Averaging Time Carbon Monoxide 9 ppm (10 mg/m 3 ) 8-hour (1) None 35 ppm (40 mg/m 3 ) 1-hour (1) Lead 0.15 µg/m 3 (2) Rolling 3-Month Average Same as Primary 1.5 µg/m 3 Quarterly Average Same as Primary Nitrogen Dioxide 53 ppb (3) Annual (Arithmetic Average) Same as Primary 100 ppb 1-hour (4) None Particulate Matter (PM 10 ) 150 µg/m 3 24-hour (5) Same as Primary Particulate Matter (PM 2.5 ) 12.0 µg/m 3 Annual (6) (Arithmetic Average) Same as Primary 35 µg/m 3 24-hour (7) Same as Primary Ozone ppm ( hour (8) Same as Primary std) Sulfur Dioxide 0.08 ppm (1997 std) 8-hour (9) Same as Primary 0.12 ppm 1-hour (10) Same as Primary 0.03 ppm Annual (Arithmetic Average) 0.5 ppm 3-hour (1) 0.14 ppm 24-hour (1) 75 ppb (11) 1-hour None (1) Not to be exceeded more than once per year. (2) Final rule signed October 15, (3) The official level of the annual NO 2 standard is ppm, equal to 53 ppb, which is shown here for the purpose of clearer comparison to the 1-hour standard (4) To attain this standard, the 3-year average of the 98th percentile of the daily maximum 1-hour average at each monitor within an area must not exceed 100 ppb (effective January 22, 2010). (5) Not to be exceeded more than once per year on average over 3 years. (6) On March 18, 2013, EPA strengthened the annual fine particle standard by revising the level from 15.0 micrograms per cubic meter (µg/m3) to 12.0µg/m3. An area will meet the standard if the three-year average of its annual average PM 2.5 concentration (at each monitoring site in the area) is less than or equal to 12.0 µg/m3. (7) To attain this standard, the 3-year average of the 98th percentile of 24-hour concentrations at each population-oriented monitor within an area must not exceed 35 µg/m3 (effective December 17, 2006). (8) To attain this standard, the 3-year average of the fourth-highest daily maximum 8-hour average ozone concentrations measured at each monitor within an area over each year must not exceed ppm. (effective May 27, 2008) (9) (a) To attain this standard, the 3-year average of the fourth-highest daily maximum 8-hour average ozone concentrations measured at each monitor within an area over each year must not exceed 0.08 ppm. (b) The 1997 standard and the implementation rules for that standard will remain in place for implementation purposes as EPA undertakes rulemaking to address the transition from the 1997 ozone standard to the 2008 ozone standard. (c) EPA is in the process of reconsidering these standards (set in March 2008). (10) (a) EPA revoked the 1-hour ozone standard in all areas, although some areas have continuing obligations under that standard ("antibacksliding"). (b) The standard is attained when the expected number of days per calendar year with maximum hourly average concentrations above 0.12 ppm is < 1. (11) (a) Final rule signed June 2, To attain this standard, the 3-year average of the 99th percentile of the daily maximum 1-hour average at each monitor within an area must not exceed 75 ppb.

12 Page 12 of 13 Appendix 2 Air Quality Index The Air Quality Index (AQI) is EPA s color-coded tool for communicating daily air quality to the public and can be calculated for any of the criteria pollutants except lead, provided monitoring data are available. An index value above 100 indicates that the concentration of a criteria pollutant exceeded the limit established in the NAAQS. Categories of the AQI are good (green, 0-50), moderate (yellow, ), unhealthy for sensitive groups (orange, ), unhealthy (red, ), very unhealthy (purple, ) and hazardous (maroon, ; Table A-2). On March 18, 2013, EPA reduced the good to moderate breakpoint for PM 2.5 from 15.0 to ). Air Quality Index Levels of Health Concern Color Code Table A-2: Air pollutant breakpoints for the Air Quality Index.

The general public is not likely to be affected. An AQI in this category or above indicates that air pollution exceeds levels acceptable under federal air quality standards. Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects. Health alert: everyone may experience more serious health effects. Hazardous Maroon >300 (2) Health warnings of emergency conditions. The entire population is more likely to be affected. 1 Areas are generally required to report the AQI based on 8-hour ozone values. However, there are a small number of areas where an AQI based on 1-hour ozone values would be more precautionary. In these cases, in addition to calculating the 8-hour ozone index value, the 1- hour ozone index value may be calculated, and the maximum of the two values reported. 2 8-hour O 3 values do not define higher AQI values ( 301). AQI values of 301 or greater are calculated with 1-hour O 3 concentrations. 3 There is no AQI for 1-hour O 3 concentrations below the Unhealthy for Sensitive Groups level.
