FREQUENTLY ASKED QUESTIONS (FAQS) for Method2071
Is Method 207 the pre-survey for wet milling ethanol facilities
or for measuring isocyanates? On the EPA website I have found several references to EPA
Method 207 that deal with sampling of isocyanates, while I found others that are the Pre-survey for wet milling ethanol facilities.
There's been some confusion regarding Method 207. The Method 207 designation
was first given to a method for isocyanates that was proposed in 1997 (62 FR 6432),
but was never finalized. That method for isocyanates is now Other Test Method 14 (OTM-14)
and can be found on our website here.
The Method 207 designation is now assigned to the Pre-survey Procedure for Corn Wet-milling
Facility Emissions which was promulgated in 2008 (73 FR 30775). This presurvey procedure
was formerly Other Test Method 11 (OTM-11) which we will soon be clarified on our website.
