Title 326 - AIR POLLUTION CONTROL DIVISION
Article 10 - NITROGEN OXIDES RULES
Rule 5 - Nitrogen Oxide Reduction Program for Internal Combustion Engines (ICE)
Section 5-2 - Definitions
Current through March 20, 2024
Authority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11
Affected: IC 13-15; IC 13-17
Sec. 2.
The following definitions apply throughout this rule:
(1) "Affected engine" means any stationary internal combustion engine that is:
that is subject to NOx control under a compliance plan under section 3 of this rule.
(2) "Engine seasonal NOx 2007 tonnage reduction" means the year 2007 seasonal NOx emissions reductions value in tons for a large NOx SIP Call engine. This is calculated as the difference between the 2007 ozone season base NOx emissions and the 2007 ozone season budget NOx emissions contained in the NOx SIP Call engine inventory.
(3) "Facility seasonal NOx 2007 tonnage reduction" means the total of the engine seasonal NOx 2007 tonnage reductions attributable to all of an owner or operator's large NOx SIP Call engines.
(4) "Large NOx SIP Call engine" means a stationary internal combustion engine identified and designated as large in the NOx SIP Call engine inventory as emitting more than one (1) ton of NOx per average ozone season day in 1995.
(5) "NOx SIP Call engine inventory" means the inventory of internal combustion engines compiled by U.S. EPA as part of the NOx SIP Call rule, including technical amendments announced in the March 2, 2000, Federal Register notice (65 FR 11222)*, and the adjustment of the 2007 budget NOx control efficiency to eighty-two percent (82%) for large gas-fired engines announced in the April 21, 2004, Federal Register notice (69 FR 21604)* for the Phase II NOx SIP Call rule.
(6) "Ozone season" means the time period between May 1 and September 30.
(7) "Past NOx emission rate" means the following:
(8) "Projected NOx emission rate" means the projected NOx emission rate in g/bhp-hr after installation of controls on an affected engine.
(9) "Projected operating hours" means the projected actual number of hours of operation per ozone season for an affected engine.
(10) "Stationary internal combustion engine" means any internal combustion engine of the reciprocating type that is either attached to a foundation at a facility or is designed to be capable of being carried or moved from one (1) location to another and remains at a single site at:
for more than twelve (12) consecutive months. Any engine that replaces an engine at a site that is intended to perform the same or similar function as the engine replaced is included in calculating the consecutive time period.
