is&KSM & IMPROVE Pfotocol Assessments: Outcomes
Recommendations
As the output of the CSN and IMPROVE Protocol Assessments, five recommendations
were made and ultimately implemented. Feedback was received and incorporated
from EPA management and regional staff, state and local monitoring agencies, and
university, research and local communities.
Recommendation #1 - Eliminate the CSN PM2.5 mass measurement
•	The CSN mass measurement was widely used when the network was established.
•	Now, the FRM mass measurement is widely used for model attainment, model evaluation,
design values, and other purposes.
•	The majority of the CSN sites have an FRM that is also providing a PM2.5 mass
measurement.*
•	Extensive analysis has been conducted demonstrating that the CSN and FRM PM2.5 mass
measurements compare well. Any differences in the measurement can primarily be
explained by the differences in the measurement techniques (e.g., sample volume, sampler
design, etc.)
•	A QA check can still be conducted by performing a mass balance and comparing to the FRM
PM2.5 mass measurement.
•	Information regarding the comparison of these methods is found in FRM versus CSN Mass.pdf
•	The CSN PM2.5 mass measurement was eliminated in October 2014 (last sample collected
September 29th).
*The few sites that do not have FRMs will continue the CSN PM2.5 mass measurement until such
time as an FRM is established.
Recommendation #2 - Reduce sample frequency at 3 CSN Sites
•	Sample frequency was reduced to 1 -in-6 at CSN Supplemental sites that are not NCore or
STN in January 2015 (Arnold West, MO, Wylam, AL and Albany, NY).
Recommendation #3 - Reduce carbon blank collection frequency in the CSN
•	Carbon backup filter blanks were eliminated in January 2015.
•	The number of field blank filters were reduced to the lowest level needed to adequately
support organic carbon (OC) artifact correction for the CSN.
•	As of February 2015, carbon field blanks are collected at 26 representative 1 -in-3 day CSN
sites and 23 representative 1 -in-6 day CSN sites at a frequency of 1 per month.
•	The full report on the recommendations for field blank collection for the CSN can be found
in Carbon Field Blank Final Report.pdf
•	UPDATE: starting in March of 2017, field blanks for all filter types (including carbon) are
now collected at a frequency of 1 per month at all CSN sites.
Recommendation #4 - Reduce ice packs in shipping in the CSN
1/8

-------
6/25/2020	CSN & IMPROVE Protocol Assessments - Outcomes
•	The number of icepacks included in sample shipments was reduced in October 2014 from 8
to 6 during the cooler months of the year (October 1 - March 31).
Recommendation #5 - Defund CSN and IMPROVE Protocol sites
•	After incorporating scoring, intangibles, and feedback from stakeholders, 38 CSN sites were
defunded by January 2015 and 8 IMPROVE Protocol sites were defunded by January 2016.
