with a flow rate less than 0.0085 scm/min or a total VOM concentration of less
than 500 ppmv, less methane and ethane, as measured by Method 18, or a
concentration of VOM of less than 250 ppmv as measured by Method 25A. However,
such operations remain subject to the performance testing requirement listed in
Section
218.433
of this Subpart, as well as the reporting and recordkeeping requirements
