Section 326IAC2-9-14. Internal combustion sources

   (a) Any stationary internal combustion source, including any combination of turbines, reciprocating engines, or engines, may elect to comply with this section by complying with section 1 of this rule and limiting fuel usage for every twelve (12) month period to less than the limits found in:

(1) subsection (e), Table 1 for a single fuel or a combination of two (2) fuels; or

(2) subsection (f), Table 2 for a single fuel or a combination of two (2) fuels.

  (b) Sources electing to comply with subsection (a)(1) must be able to demonstrate compliance not later than thirty (30) days after receipt of a written request by the department or U.S. EPA. No other demonstration of compliance shall be required. A source specific operating agreement is not required for these sources.

(1) comply with the requirements of section 1 of this rule; and

(2) submit a request for a source specific operating agreement.

  (d) For sources complying with subsection (a)(2), the following records shall be kept at the source:

(1) Monthly hours operated for each combustion unit.

(2) Records of annual fuel usage for each combustion unit.

(3) Routine maintenance records.

  (e) Table 1 limits shall be as follows:
