
If comparing to standard, MUST use FRM or
FEM; see 40 CFR 50.7
◦ Also look at Appendix C to 40 CFR Part 58 –
Ambient Air Quality Monitoring
Methodology


You may have purposes other than
comparing to NAAQS, and you may want
different types of instruments to suit your
goals
Can use an FRM (class 1, filter-based), FEM
class II (filter-based, like dichots), or FEM
class III (continuous), or ARM (someday)
5



6 PM2.5 continuous methods have been
approved as FEMs
PM2.5 Continuous Monitoring
http://www.epa.gov/ttn/amtic/contmont.html
If PM2.5 continuous FEMs meet Part 53 criteria
used to approve the instrument by comparing to
collocated FRMs, EPA supports use of the
continuous FEM as a Primary monitor (see
spreadsheet for the calcs at above website, and


ARM = Approved Regional Method

No ARMs yet
Process of establishing an ARM is the same as
an FEM, must collocate FRM and produce 90
+ sample pairs per year with 20 ea season
Use same spreadsheet to evaluate data

Regional office must approve (natch)





An approved FEM can be designated as
primary
The FEM can be collocated with FRM, the FRM
being primary
An ARM FEM can be approved (takes at least a
year of operation to gather enough data, plus
time for approval)
Approved primary FEM or ARM would then
report to AQS as 88101, POC 3


Same CFR requirements for filter (FRM-17
methods) and dichot (2 methods) and continuous
(6 methods), although there are separate
validation templates for filter, continuous & dichot
(http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/session%20
1-QA%20systems,%20PQAOs/)

collocation:
◦ if <= 3 sites, at least 1 FRM collocated with one FEM
◦ 1/12 days for SLAMS, 1/6 for PSD



PEP five times each year if fewer than 5 sites
FR checks every 4 weeks(RP) with own stnd
FR audit every 6 months(RA) with outside stnd




FRM are all filter-based methods
(40 CFR 50 App. J)
FEM includes continuous methods (40 CFR
53)
BOTH can be compared to the NAAQS for
PM10 (40 CFR 50.7)
16


Hi-vol (1130 lpm) method (used for TSP)
with PM10 inlet that directs only PM10 to
filter; guidance in EPA Handbook 2.11
Lo-vol sampling at 16.7 L/m; see EPA
Handbook 2.10; can be either:
◦ Dichot method which split into PM2.5 and PM10;
both filters are weighed
◦ Lo-vol sampler (R&P, Andersen, and BGI all
approved as FRM PM10)

As for all PM, it all hinges on flow rate and
careful filter handling

Laboratories!
◦ The TAMS Center laboratory provides exemplary reports;
examples available for you to urge your lab to copy:
http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/ses
sion%207-PM/
◦ Also ask for quarterly QC reports
◦ TAMS gravimetric services:

http://www4.nau.edu/tams/services/filterlab.asp
Flow rate standards must be verified annually,
some
guidance in Redbook
http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/EPA%
20guidance%20and%20other%20reference%20material/

Data management (filters require chain of custody; see
example COC forms for PEP program in session 7 folder )
23

You may be using a non-FRM/FEM, so you
can report to AQS using the non-regulatory
guidance:
http://www.epa.gov/ttn/airs/airsaqs/memos/Non%20Regulat
ory%20Monitor%20Type%20Guidance.pdf


Flow rate and pressure calcs are made easier

REPORT NEGATIVE VALUES: see your MDL in
the table AQS_SplgMethodsFromToolbox.xls in session
7 folder:
◦ TEOMs MDL ranges from -10 to -50
◦ BAMS MDL ranges from -10 to 4 mg/m3

It ALL hangs on flow rate
PM2.5 PEP auditing necessary for NAAQS data
Your instrument may be able to do “better”
than validation criteria, see your spec sheets
