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 (PM2.5) 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 PM2.5 monitored in August throughout the network are

shown in Figure 2.

August 2013 Activity Report

Figure 2: PM2.5 multi-station time series for August 2013.

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, https://fortress.wa.gov/ecy/enviwa/Default.htm.

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.

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.

August 2013 Activity Report

Page 9 of 13

Figure 4: The PM2.5 pollution rose depicts the variation of hourly average PM2.5 3) with the direction

from which the wind was blowing in August.

Ground-level ozone (O3), 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 0.071 ppm (August 12; Figure 5). Eight hour average ozone concentrations in

the range 0.06 to 0.075 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 0.075 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.

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 (NO2) is 100 ppb. The

NAAQS does not set limits on the other air pollutants shown here.

August 2013 Activity Report

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 (NO2), particulate matter (PM10 and PM2.5), ground-

level ozone (O3) and sulfur dioxide (SO2; 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).

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 PM2.5 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 0.075 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 ("anti-backsliding").

(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, 2010. 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.

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, 51-100), “unhealthy for sensitive groups”

(orange, 101-150), “unhealthy” (red, 151-200), “very unhealthy” (purple, 201-300) and “hazardous” (maroon, 301-

500; Table A-2). On March 18, 2013, EPA reduced the good to moderate breakpoint for PM2.5 from 15.0 to 12.0 3).

1Areas 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.

28-hour O3 values do not define higher AQI values (≥ 301). AQI values of 301 or greater are calculated with 1-hour O3 concentrations.

3There is no AQI for 1-hour O3 concentrations below the Unhealthy for Sensitive Groups level.
