UPDATE RE: PM Testing - update from Ned

Katie  -  Lucky for us, Ned was checking his email on his day off. He agreed with your plan and made the follow comments:
 
It is likely AECOM is pulling gas into the train way too hard; the maximum sample rate for the train is 0.75 cfm. However, it doesn't sound like detection limits are going to be an issue, so we can drop the criteria to 2 dscm and ask AECOM to lower the sample rate to around 0.5 cfm.
 
Thanks,
Ned

Hi. Kevin and Ned are both out today. I believe they will be able to respond to you first thing Monday morning (assuming no hurricane damage or internet issues in the interim). 
 
If you need to test before we can get back to you, then continue with your reduced volume plan.
 
Were you able to get any valid 3-hour runs?

Subject: PM Testing
 
Hi Donna Lee,
 
We are having some issues with the sample volume requested for the PM testing.  Collecting 3 dscm is creating problems with the sampling train.  See bulleted list below from AECOM who is currently on site doing the testing.  We do not believe there is an issue with detection limits since we are getting significant PM on the filters.  Per AECOM's request below, would it be ok to reduce the sample volume for the PM samples to 2 dscm?
 
* Particulate loading at the M5 filter and at the CPM filter has required changing of both filters multiple times during the 3-hour test runs.   While this has been done carefully to avoid contamination of the samples, we would like to avoid disassembling the train during the runs as much as possible.
* The sustained exposure to the PM filter to the heat from the stack gas (average 1500-1800F) has strained the integrity of the filter and filter support, especially under the high pressure differentials generated under the high PM loading during the production run.  We had one Method 5 filter fail by splitting during the latter part of the run.
* The high loading during the runs is an indicator that there is not a problem with detection limits on PM.   I'm recommending that we plan subsequent runs for 2 hours (and 2 dscm) instead of 3.   We put 2-hour runs in our sampling protocol for the CD tests submitted to the State of Ohio.
 
Thanks,
