Additional FAQ on M0031 during pushing

An additional FAQ:

24.     We are going to be testing on a pushing process next week that pushes for roughly 2 minutes, then is down for around 10 minutes. For a 12-hour shift, I believe there will be about 48 pushes. We are running into difficulty trying to figure out how to sample the Method 0031 train (for VOHAP) and collect a good, representative sample within the confines of the method which requires 20 minutes of sample/set of traps, 120 minutes of sample time, etc.. The problem is that I don't think we can get the 120 minutes of sample, which means we then leave the train assembled and covered overnight, which doesn't bode well for our data on the back end I wouldn't think.

EPA Response: The 2-hour sampling time in the method is assuming a constant process. Since this process is intermittent, you may disregard the total sampling time requirement.  Hopefully, this will alleviate your concern with leaving the train assembled and covered overnight
