A natural gas dehydrator has several emissions points. Is each emission point considered a fee unit?
A. No, a dehydrator is generally considered one fee unit, including emissions from both the still vent and combustion source. If the emissions from the still vent are combusted in a flare, another emission unit would be added for the flare. However, if the emissions from the still vent are directed to a condenser, no additional fee units are assessed because no new emissions are created. If dehydrator emissions are re-injected into the pipeline, no additional fee units are assessed. In the definition, a fee unit must generate, create, or be the source of a regulated air contaminant. Operating Scenarios Q. I have five engines at my compressor station. I am applying for a permit, which allows different operating scenarios; i.e., the permit allows me to simultaneously operate engines #1, 2, & 3 or 3, 4, & 5. How many fee units are there? A. Five, the total number of engines. However, if an operating scenario is requested in the application, and it requires additional analysis and permit c
