Providence, RI NATTS Network Assessment Review
• Established 2003: Carbonyls, PMio Metals, and VOCs
o Chromium VI added in 2005; ended in in 2013
o PAHs added in 2008
• For the NATTS Network Assessment (2003-2018):
o 18 of 18 Method Quality Objective (MQO) Core HAPs were included in the national trends
o 254 of 268 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 (benzene, 1,3-butadiene, naphthalene, nickel (PMio), tetrachloroethylene,
and trichloroethylene).
o 100% Reporting of Datasets
• Method Quality Objectives (MQO): 2003-2018
o Completeness: Met 85% completeness in 254 of 268 pollutant datasets
o Method Detection Limits: Met MDL Target Ratio of 1.00 in 252 of 271 pollutant datasets
o Bias: Met ±25% for 204 of 216 pollutant datasets
o Overall Method Precision: Met <15% CV for 76 of 108 pollutant datasets
o Analytical Method Precision: Met <15% CV for 92 of 117 pollutant datasets
• Analytical Laboratories for 2018

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.

No data available
a: No Proficiency Test samples were sent for this pollutant and year.
b: Proficiency Test results are from the National Contract Lab for EPA's School Air Toxics Monitoring Program. The %Difference was -5.55% in 2009 and 10.53% in 2010.
c: Pollutant was sampled at this site and year, but no bias data were reported.
d: This site was supported by EPA Region 1 and another laboratory for this pollutant and year. However, only EPA Region 1 PT data were available.
e: Pollutant was expected, but not sampled at this site for this year.
f: The Proficiency Test sample for this pollutant was 0; the site reported a concentration as "< MDL", rather than 0. EPA accepted this result.
8: Although a Proficiency Test sample was sent to the lab supporting this site and year, the results were nullified by EPA due to QA issues.

Does Not Meet: >25% CV or did not report Precision (required in the NATTS Workplan Template since 2012)
No data available
a: Although both primary and secondary data were reported, both sets of values were less than the MDL. Thus no %CV was calculated.

A-rated:< 15% CV
B-rated: Between 15%CV to25% CV
Does Not Meet: >25% CV or did not report Precision (required in the NATTS Workplan Template since 2012)
No data available
a: The primary and/or replicate value were less than the MDL, so no calculation could be made.
b: Per the NATTS Workplan template, analytical replicates were required to be reported to AQS for this sampling year
