Chesterfield, SC NATTS Network Assessment Review

Established 2004: 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 (2004-2018):

o 6 of 18 Method Quality Objective (MQO) Core HAPs were included in the national trends

¦	Acetaldehvde. Bcnzo(a)pvrcnc. Formaldehyde, and Naphthalene: Completeness less than 75% for
2018.

¦	Benzene: Reported MDL to NATTS Target MDL ratio greater than 2.0

¦	1.3-Butadiene. Carbon Tetrachloride. Manganese (PMm). Tetrachloroethvlene. Trichloroethvlene.
and Vinyl Chloride: Reported MDL to NATTS Target MDL ratio greater than 2.0, Bias %
Difference was outside of ±35%, and Precision PCT CV was greater than 25%.

¦	Chloroform: Bias % Difference was outside of ±35%
o 185 of 248 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 some pollutants (benzene and naphthalene)
o 100% Reporting of Datasets

Method Quality Objectives (MQO): 2004-2018

o Completeness: Met 85% completeness in 237 of 248 pollutant datasets
o Method Detection Limits: Met MDL Target Ratio of 1.00 in 174 of 256 pollutant datasets
o Bias: Met ±25% for 174 of 220 pollutant datasets

o Overall Method Precision: Met <15% CV for 51 of 157 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.

a: Although this pollutant was sampled for at this site and year, the laboratory equipment was not operating at the time the Proficiency Test sample was sent.
b: No Proficiency Test samples were sent for this pollutant and year.

c: 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.
d: Pollutant was sampled at this site and year, but no bias data were reported.

e: The Proficiency Test sample for this pollutant was 0; the site reported a concentration as "< MDL", rather than 0. EPA accepted this result.
f: 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.

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: Per the NATTS Workplan template, analytical replicates were required to be reported to AQS for this sampling year
b: The primary and/or replicate value were less than the MDL, so no calculation could be made.
