Spokane Regional Clean Air Agency

Air Quality Report - April 2014

Air quality remained in the “good” range of the Air Quality Index (AQI) for carbon monoxide (CO), particulate matter

(PM10) and fine particulate matter (PM2.5) throughout the month of April (Figure 1).

See Appendix 1 of this report for information about federal air quality standards or Appendix 2 for a description of the AQI.

Figure 1: Air Quality Index (AQI) values for April 2014

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 April throughout the network are shown in Figure 2.

Figure 2: PM2.5 multi-station time series for April 2014

April 2014 Activity Report

Page 8 of 13

The April 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 the Washington State Department of Ecology using its 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.

As is typical for the Spokane area, air quality in April was generally better with southwesterly winds associated with storm

systems (Figures 3 and 4). Fine particulate matter mass concentration data are from the monitoring station located at Monroe

St. and Wellesley Ave. in Spokane.

Figure 3: The wind rose depicts the variation of hourly average wind speed (mph) with the direction from which the

wind was blowing in April.

which the wind was blowing in April.

April 2014 Activity Report

Page 10 of 13

Nitrogen oxides (NOx) are a group of highly reactive gases that contain nitrogen and oxygen. In ambient air, they consist

primarily of nitric oxide (NO) and nitrogen dioxide (NO2). The 2005 emissions inventory estimated that, on an annual basis,

59% of NOx emissions in Spokane County are from on-road mobile sources, cars and trucks, and 24% are from non-road

mobile sources, e.g., construction heavy equipment. The remaining 17% comes from a variety of sources, such as natural

emissions from soil and vegetation (6%), industrial, commercial and institutional point sources (5%), residential fuel use

(4%), e.g., natural gas and oil for heating and cooking, wood stoves and fireplaces (1%) and open burning, wildfires and

structure and vehicle fires (1%).

The SRCAA monitors nitrogen oxides at the Spokane Augusta & Fiske monitoring station. Nitrogen dioxide is a criteria air

pollutant defined in the NAAQS (see Appendix 1 of this report), but is not a significant problem in the Spokane area. The

one-hour maximum concentrations of the nitrogen oxides monitored in April at the Augusta & Fiske monitoring station are

shown in figure 5.

Figure 5: One hour maximum concentrations of nitrogen oxides and hydrocarbons for Spokane Augusta Ave

monitoring station in April. 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. The NOX analyzer was disrupted April 25-27

during work to set up ozone monitoring for the summer season.

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) Not to be exceeded more than once per year. (2) Final rule signed October 15, 2008. (3) The official level of the annual NO2 standard is 0.053 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) To attain this standard, the 3-year average of the weighted annual mean PM2.5 concentrations from single or multiple community-

oriented monitors must not exceed 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. (12) EPA revised the annual PM2.5 standard from 15 to 12 µg/m3 (effective March 18, 2013).

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

April 2014 Activity Report

Page 12 of 13

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). The breakpoint between the -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.
