Air Testing (Ozone test method)

Curious if you (or others) ever made any progress or got resolution on this question.  I have bumped up against the same issue... have a project where we are having trouble finding a lab that does any of the listed methods for ozone, but offers OSHA ID 214.  One of the advantages of this method listed is that it is capable of monitoring for the EPA limit if a sampling rate of at least 0.5 L/min is used.  Would this qualify as an "EPA designated method for Ozone"?

Since the project is registered under v4 and is not in a non-attainment area, we techically could probably skip the ozone test by not upgrading to v4.1 but we have another lab complication in that TO-15 was stricken from v4 for VOC testing and the same lab uses TO-15 but not TO-17.  So the interest in upgrading to v4.1 was spurred by the ability to use TO-17 for VOCs.  For a follow on question, does anyone know why TO-15 was stricken from v4 (LEED addendum #100002033) but then added back into v4.1 only (and not added back into v4)?  Or did I miss something?  

Bryana,

As far as I can see they still have TO15 on the V4 list, it is called IP-1A which is TO-15 or TO-15a. The EPA IP methods were written well before the EPA TO methods. In the 90's EPA TO methods came out following stricture guidelines that were lacking in the IP methods. They are both one in the same with the exception you can do a lot more compounds with TO-15 over IP-1A due to advancements in technology. From what I can see in LEED 4.1 switched it to the proper method.

However, according to the criteria you must use a ISO17025 certified laboratory that uses ISO methods which Centek Lab is. We have been doing LEED testing since 2009 for all the parameters. Here are a couple of updates that we have been doing that may interest you. 

For ozone the method that is stated for ozone is an analytical method but not a collection method. Ozone breaks down within 20-40 minutes and as known as ozone depletion compounds. We do have meters that you can use from us that goes down to the detection limits that is needed for V4 and 4.1

Formaldehyde due to supply chain issues it has been almost impossible to get formaldehyde tubes. Centek has received permission to do formaldehyde in the canisters using EPA method TO-15 which has been approved by the EPA and ISO certification back in the 90's. This will save you both time and money not to mention all the CO2 emissions, municipal and hazardous waste. Therefore with 1 canister you can get you TVOC, CO and aldehydes.
