Overview of PM session: • Overview of FRM/FEM/ARM status, requirements, and reporting • QC (routine checks, audits, and method-specific QC) for: • Filter and Continuous PM2.5 • Filter and Continuous PM10 • Minivols • General PM QC issues
FRM=Federal Reference MethodFEM = Federal Equivalent Methodnew list available as of 2/1: http://www.epa.gov/ttn/amtic/files/ambient/criteria/reference-equivalent-methods-list.pdf • Draft SOPs for approved FEMs written by EPA in our course downloads folder at: http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/session%207-PM/EPA%20Draft%20Continuous%20PM%20SOPs/ • Thermo 8500C FDMS – Recently delivered from STI - looking for Reviewers; please contact Tim Hanley at: hanley.tim@epa.gov
For NAAQS • 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)
§50.7 NAAQS for Particulate Matter 2.5 Microns and Smaller • 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 ppt explanation in session 7 folder at http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/session%207-PM/
Approved PM2.5 Class III FEMs • Met One BAM-1020 Monitor – EQPM-0308-170 • Thermo Scientific Model 5014i or FH62C14-DHS – EQPM-0609-183 • Thermo Scientific Model 5030 SHARP – EQPM-0609-184 • Thermo Scientific Series 8500C FDMS – EQPM-0609-181 • Thermo Scientific 1405-DF FDMS – EQPM-0609-182 • GRIMM Model EDM 180 PM2.5 Monitor – EQPM-0311-195
ARMs ? • 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 http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/session%207-PM/ • Regional office must approve (natch)
3 scenarios for PM2.5 continuous for NAAQS: • 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
How to report PM2.5 FRM/FEM data? • http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/session%207-PM/contrept.pdf • And http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/session%207-PM/femarmslam.pdf • Remember all QA requirements apply: • Collocation, FR checks, PEP audits in Appendix A: http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/session%201-QA%20systems,%20PQAOs/ • Siting (Appendix E) http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/session%207-PM/
PM 2.5 QC Overview: • See e-cfr, or: http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/session%201-QA%20systems,%20PQAOs/
Who can do these, and with what? General info on filter methods in guidance doc 2.12: http://www.epa.gov/ttn/amtic/files/ambient/pm25/qa/m212covd.pdf
PM2.5: • 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%201-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
Hints and tips for PM2.5: • Lab • Never ship on a Friday • Find what works for you and work with the lab • Metal vs. plastic filter covers • Send AQS raw data monthly • Keep up communications • Have a good aqs contractor • Get to know and trust • Double check their work • Train in good back-up people
Hints and tips for PM2.5: • Backpack ready • PM field log book and Field log book • SOPs and quick look maintenance schedule • Calendar with 1:6 schedule • Delta Cal instructional book • O-ring kits and grease • WINS impactor filters/oil • Flow disks • Cleaning supplies • Writing utensils for all weather • Keys
Hints and tips for PM2.5: • EPA • Withdraw of funds – fought to keep monitors • Don’t take no for an answer – present case • No other PM monitoring in area – can’t rely on other data • Don’t rely on for audits, have a back up plan • Do what type of monitoring is best for the Tribe • Look at worst case scenario, legal aspect
§50.7 NAAQS for Particulate Matter 10 Microns and Smaller • 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)
PM10 FRM: 2 Methods • 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) Both handbooks at: http://www.epa.gov/ttn/amtic/qapollutant.html
PM10 FEM: 2 Methods • TEOMs • BAMs • See TAMS Center’s course material specific to these methods: • http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/BAM%20checklists/ • http://itep68.itep.nau.edu/itep_downloads/BAM_Resources/ • http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/TEOM%20docs/ • http://itep68.itep.nau.edu/itep_downloads/TEOM_Resources/
PM 10 manual QC: (hi-vol or lo-vol doesn’t matter to the 15%)
PM 10 automated QC: Plus whatever your instrument manuals call for; see example QC sheets in the session 7 folder, and the EPA example SOPs have QC sheets appended: http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/session%207-PM/
Minivols: • As for all PM, it all hinges on flow rate and careful filter handling • http://itep68.itep.nau.edu/itep_downloads/MiniVol_Resources/
General PM QC issues: • 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/session%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)
More PM issues: • 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%20Regulatory%20Monitor%20Type%20Guidance.pdf • Flow rate and pressure calcs are made easier with free program: http://www.unitconverterpro.com/ • 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
QC forms specific to your instrument are available in EPA draft SOPs in course downloads folder:
PM Monitoring Conclusions: • 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 • Course website: http://itep68.itep.nau.edu/itep_downloads/QA101_Resources/ • Our emails: • Brandy Toft air@lldrm.org • Melinda.ronca-battista@nau.edu • Christopher.lee@nau.edu
