File a report with the Environmental Protection Agency to shut down the facility and discontinue the use of the sulfur dioxide online monitor.
It is best to use natural gas as the fuel gas, as this will have a lesser impact! However, it is possible to apply for exemption from assessment for starting or stopping operations!
