(3) In the Notification of Compliance Status report, the owner or operator may elect to establish both a maximum daily average operating flowrate limit above the flowrate setpoint and a reduced outlet concentration limit corresponding to this flowrate limit. The owner or operator may also establish reduced outlet concentration limits for any daily average flowrates between the flowrate setpoint and the flowrate limit. The correlation between these elevated flowrates and the corresponding outlet concentration limits must be established using Equation 64 of this subpart: View Image
Where:
Ca = adjusted outlet concentration limit, dry basis, ppmv
50 = outlet concentration limit associated with the flowrate setpoint, dry basis, ppmv
Fs = system flowrate setpoint, scfm
Fa = actual system flowrate limit, scfm
