La Grande, OR NATTS Network Assessment Review
Established 2004 (La Grande (#1), OR); relocated approximately 1.25 miles southeast in September 2016 and
continued without interruption (La Grande (#2), OR): Carbonyls, PAHs, PMio Metals, and VOCs
o Chromium VI began in 2005 and ended in in 2014
For the NATTS Network Assessment (2004-2018):
o 10 of 18 Method Quality Objective (MQO) Core HAPs were included in the national trends
¦ Benzene. Carbon Tetrachloride. Tetrachloroethvlene. and Vinyl Chloride: Low completeness in
2015.
¦ 1.3-Butadiene: Low completeness in 2015; Bias Percent Difference outside ± 35% and analytical
precision data not reported in 2013 and 2014.
¦ Chloroform: Low completeness in 2015; Bias Percent Difference outside ± 35% and analytical
precision data not reported in 2018.
¦ Naphthalene: Bias Percent Difference outside ±35% and analytical precision data not reported in
2016 and 2018.
¦ Trichloroethvlene: Bias Percent Difference outside ± 35% in 2018 and analytical precision data
not reported in 2014, 2016, and 2018.
o 214 of 258 pollutant datasets were suitable for trends analysis
o Annual Average and 3-Year Rolling Average Concentrations were generally flat over time, with the
exception of a few pollutants (arsenic (PMio), benzene, benzo(a)pyrene, and lead (PMio)).
o 100% Reporting of Datasets
Method Quality Objectives (MQO): 2004-2018
o Completeness: Met 85% completeness in 220 of 258 pollutant datasets
o Method Detection Limits: Met MDL Target Ratio of 1.00 in 221 of 259 pollutant datasets
o Bias: Met ±25% for 175 of 222 pollutant datasets
o Overall Method Precision: Met <15% CV for 0 of 0 pollutant datasets
o Analytical Method Precision: Met <15% CV for 19 of 116 pollutant datasets

National Summary: NATTS data were collected at 27 locations across the United States,
with sites beginning in 2003 or later (Figure 1) for 19 core HAPs. Over 528,000 concentrations
(primary, secondary, and replicate) were generated and analyzed for this assessment. Pollutant
datasets were scored to assess whether they were suitable for trends analysis. Each
pollutant dataset was evaluated against four MQOs: Completeness; Sensitivity; Bias; and
Precision. Datasets that were suitable (A- or B-rated) for six consecutive years were used for
national trends analysis (Table 1).
National trends were determined by comparing the most recent 3-year blocked averages
(e.g., 2013-2015 vs. 2016-2018) to determine if the NATTS Trends DQO was being met:
To be able to detect a al5percent difference (trend) between the annual mean
concentrations of successive 3-year periods within acceptable levels of decision error.
Of the 19 core HAPs. 18 were assessed for the NATTS Trends DQO. Due to sampling and
analytical issues, acrolein was not considered for trends analysis (Table 2). This assessment
showed that across the network, 15 of those 18 pollutants were decreasing between the
3-year blocks, while two of those pollutants were increasing between the 3-year blocks.
One pollutant did not exhibit a trend.

3 Statistics presented are from pollutant datasets which were suitable for trends.
b The arithmetic mean is the average of all samples results which include actual measured values. If no chemical was registered, then a value of zero is
used when calculating the mean.
c ND: No results of this chemical were registered by the laboratory analytical equipment.
