I don’t know about other facilities, but in ours we track fugitive emissions. Every flange and connection is tagged, and they come around about once per quarter with portable emissions equipment and test each connection. Those that fail have to be repaired within a certain amount of time, like 3-30 days, and if they’re not they are reported. They’re reported anyways, but you may have what’s called a Title V deviation. They also monitor our flares, which are a big emissions source because not all the combustible gas is destructed. When you’re burning millions of pounds of HRVOCs you’re going to release thousands of pounds of unburned chemicals, unless you’re using a thermal oxidizer.
There’s no bullshit either. If we leak it, they report it. They’re very strict on that, internally. And, we’ve actually upgraded our emissions checking equipment over time to get better results. Faster GC’S, more sensitive GC’S, better flow meters, etc.
