Compliance with this Section according to this Rule does not remove or reduce any applicable requirement of the Acid Rain Program.

(d)  To comply with the requirements of this Section through the seasonal combustion of natural gas, the owner or operator shall submit to the Director the following information:

(1)           the name and location of the facility;

(2)           information identifying the source to use seasonal combustion of natural gas for compliance;

(3)           the maximum heat input rate for each source;

(4)           a demonstration that the source will comply with the applicable limitation for the combustion of coal during the ozone season;

(5)           a demonstration that the source will comply with the NOx emission limitation established under Paragraph (c) of this Rule beginning October 1 and ending April 30; and
