RE: bypass hours

Hello!

If two bypass vent stacks are open for 1 hour, that would count as 2 venting hours.

Please note, the permit hours listed below are "per vent stack".  For example, Middletown's limit is 1,560 venting hours per year, which divided by 5 vent stacks equals 312 venting hours per each vent stack.

Let us know if you have more questions.

Kris

Hi. I have a question about bypass hours. I know you all have permitted maximum bypass hours. See below. My question is, if two bypass waste stacks are being used from let's say 2pm to 3pm, as an example, is that counted as one bypass hour or two bypass hours for permit purposes?
