applicable limits specified in Section 301 of this rule within two years. Included in 

this application, the owner or operator shall submit an emission control plan that 

includes a schedule of increments of progress for the installation of the required 

control equipment. This schedule shall be subject to the review and approval of 

the Air Pollution Control Officer.

October 8, 2015 

provisions of this rule shall perform the following actions: 

501.1 Install, operate and maintain in calibration equipment, as approved by the Air 

Pollution Control Officer that continuously measures and records the following:

Operate, information correlating the control system operating parameters to the 

associated NOx output. This information may be used by the Air Pollution Control 

Officer to determine compliance when there is no continuous emission 

monitoring system for NOx available or when the continuous emission monitoring 

system is not operating properly.
