St. Louis, MO NATTS Network Assessment Review

•	Established 2003: Carbonyls, PMio Metals, and VOCs

o Added Chromium VI in 2005, completed in 2014
o Added PAHs 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	259 of 263 pollutant datasets were suitable for trends analysis

o	Annual Average and 3-Year Rolling Average Concentrations were generally decreasing over time,

o	100% Reporting of Datasets

•	Method Quality Objectives (MQO): 2003-2018

o	Completeness: Met 85% completeness in 263 of 263 pollutant datasets

o	Method Detection Limits: Met MDL Target Ratio of 1.00 in 259 of 272 pollutant datasets

o	Bias: Met ±25% for 212 of 226 pollutant datasets

o	Overall Method Precision: Met <15% CV for 167 of 204 pollutant datasets

o	Analytical Method Precision: Met <15% CV for 207 of 214 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.

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: Although both primary and secondary data were reported, both sets of values were less than the MDL. Thus no %CV was calculated.
