RE: pressure monitoring vs leak detection


Hi,
I'm assuming that when you refer to "existing" plants you mean currently existing, not existing per the original Subpart L standards.

If that's the case, then of the 5 existing heat and/or non-recovery plants, all 5 of these plants monitor the pressures daily in a common battery tunnel in accordance with 63.303(a)(1)(ii) or (b)(1)(ii).

Hi. Hopefully this not too much of a problem either. Here is another item we need to verify. Please fill in the numbers in the Xs.

Coke oven doors: daily pressure monitoring: Owners or operators of X existing heat and/or non-recovery plants are required to either conduct leak detection procedures or monitor oven pressure daily.  X of these plants have elected to monitor pressure.
