O3 Verification Citation and QA Requirements
SRP O3 Verification Procedure
Most verifications done are for State primary O3 standards (Level 2)
O3 instruments previously verified @ R2 are run 3x on one day
New instruments require 6 verification runs on 6 different days (6 x 6)
Each run consists of 8 points; pre and post zero, 6 upscale concentrations
O3 can be generated by R2 EPA (for analyzers)
O3 can be generated by the State/Local Agency (for calibrators)
Analyzers can be driven to EPA R2 and left for testing
Shipment via UPS/FedEx/etc., only with Pelican 1660 case or equivalent

Verification Results
Acceptance Criteria: Traditionally slope 1.00 ± 0.03, intercept ± 3 ppb at all points all runs
New Acceptance Criteria for Level 2 Standard: ± 3% bias at all points and all runs
If criteria are not met, instrument can not be used as the State Level 2 standard
No adjustment of monitoring can be done based on verification results

Flow Verification - Activities
Flow verifications and generation of calibration curves only – no adjustments to hardware
Verify flow standards, e.g., Bios Definer 220’s, DC-Lite, DC-1, Tetracals, etc.
Verify mass flow controllers in calibrators and GPT devices such as: • Thermo 146 series • API 703E and 700 • Environics 9100 and 6100
Flow Equipment Standards and Instrumentation @ EPA R2
BIOS DryCal ML-800 – Region 2 primary flow standard • Cell #44 - Range of 500 cc/min to 50 L/min, accuracy of reading = 0.15% • Cell #10 - Range of 5 cc/in to 500 cc/min, accuracy of reading = 0.15% • Cell #3 Range of 0.5 cc/in to 50 cc/min, accuracy of reading = 0.25%
• Cells and base are calibrated annually by the vendor, annually • Calibration involves dismantling, reassembly, upgrades, and primary recalibration from scratch • Cost of $5000 annually • Annual comparison with NYSDEC MOL-BLOC primary flow standard, annually
Definer 220’s (3 pairs of High and Low flow) – used in the field

PGVP – Brief History
ORD initially did cylinder verifications for accuracy (1980’s)
ORD divests from verifications (early 1990’s)
Cylinder verifications done by EPA R2 for our States by direct proportion method (1990- on)
OAQPS initiated PGVP Program in 2010
R2 & R7 recruited to effort by OAQPS
R2 Developed the methodology, SOPs, and spreadsheets for the program
R2 Laboratory audited and certified for operation by ORD/OAQPS
2013 totals – 37 cylinders, 44 assays
PGVP – Program Mechanics Verifications conducted quarterly, depending on demand
Cylinders arrive either from States or directly from vendors
Turnaround time of 2 weeks
• Flow calibrations • Leak check • Analyzer Calibration • Protocol assay • Calculations • Chain of Custody • Shipping
Acceptance Criteria • ± 4% accuracy of vendor certificate = PASS • ± 2%-4% = Caution
Results and certificates forwarded to EPA-OAQPS
Solicitation of verifications, follow-up of assay results, reporting, and funding done by EPA-OAQPS
ORD audits every 3 years

TTP V 3.0 - Rack 1 Annotated
DESO quick connect
Nupro valve to throttle flow to analyzers
Temperature Probe
Ethernet cable to computer (comes out the front of rack)
¼” o.d x 1/8” i.d. pigtail to hook up w/ presentation line – critical for sufficient backpressure to feed analyzers
Rotameter to measure excess flow from TTP instrument flow stream – typically 300 cc/min excess
Note the use of shelves throughout – easier insert/exit of equipment & provides surfaces for mounting cables and fittings. There are 3 shelves in rack 1
Note use of foam to make sure analyzer rack mounts match rack holes
TTP V 3.0 - Rack 1 Detail
Taps directly from the mass flow controllers and before the reaction chamber -to allow for flow measurement without having to remove the calibrator from the rack
Note serial cble from 6100 is mounted to the rack shelf, eliminating cable clutter
Plumbing lines from he front of the rack to the back (TTP analyzer feed + excess manometer flow) are secured to the perforations in the sides of the shelves. These flows have to go from the back to the front and back again in order to control the flow from the front of the rack when it is mounted in the truck.

TTP V 3.0 - Rear View of Racks 1 & 2
TTP V 3.0 - Rear View Detail of Rack 1
Environics 6100 output. 20 L/min max
output
Teflon tee 1 (rear manifold).
Feed after the NUPRO valve (comes from the front) in order to give TTP analyzers sufficient flow without excess pressure (300 cc/min excess flow)
Zero air out 30 psi; feeds tee w/ one leg to O3 Analyzer, one leg to Environics 6100 diluent air MFC.
Zero air supply line to Port 1 for dilution MFC
Feed to presentation line.
This line goes to the front to allow
connect/diconnect of presentation line from the front of he
analyzer.
Feed to DESO/Nupro valve. Feed line also goes to the front of the rack.
To O3 analyzer
TO CO analyzer
Excess flow, feeds to front panel rotameter.
Tee 2A and 2B (front manifold). Feeds TTP analyzers and excess flow.
