Generic NOx Emission Rate
* Note: August 22, 2006 rule making proposed to allow units with sulfur permit limits to convert the limits to SO2 emission rates in lieu of the defaults in Table LM-1
HIqtr = OPHrsqtr x MRHI
*Note – While certain paragraphs of §75.19 reference sections of Appendix D the methodology is still LME
At the end of each reporting period, the total heat input is apportioned to each operating hour by load.
The NOx emission rate is multiplied by the hourly heat input value to determine the NOx mass emissions (lb/hr) for each hour of operation.
