SAN DIEGO COUNTY AIR POLLUTION CONTROL DISTRICT
RULE 260.332 - STANDARD FOR NITROGEN OXIDES
(Rev. Effective 11/24/82)
(a) On and after the date on which the performance test required by Rule 260.8 is completed, every owner or operator
subject to the provisions of this subpart, as specified in Sections (b), (c), and (d) of this rule, shall comply
with one of the following, except as provided in Sections (e), (f), (g), (h), (i), (j), (k), and (l) of this rule.
(Rev. Effective 11/24/82)
STD = allowable NOx emissions (percent by volume at 15 percent oxygen and on a dry basis).
Y = manufacturer's rated heat rate at manufacturer's rated load (kilojoules per watt hour) or, actual measured heat rate based on lower heating value of fuel as measured at actual peak load for the facility. The value of Y shall not exceed 14.4 kilojoules per watt hour.
F = NOx emission allowance for fuel-bound nitrogen as defined in Subsection (3) of this section.
where:
STD = Allowable NOx emissions (percent by volume at 15 percent oxygen and on a dry basis).
Y = manufacturer's rated heat rate at manufacturer's rated peak load (kilojoules per watt hour), or actual measured heat rate based on lower heating value of fuel as measured at actual peak load for the facility. The value of Y shall not exceed 14.4 kilojoules per watt hour.
F = NOx emission allowance for fuel-bound nitrogen as defined in Subsection (3) of this section.
where:
N = the nitrogen content of the fuel (percent by weight)
or:
Manufacturers may develop custom fuel-bound nitrogen allowances for each gas turbine model they manufacture. These fuel-bound nitrogen allowances shall be substantiated with data and must be approved for use by the Administrator before the initial performance test required by Rule 260.8. Notices of approval of custom fuel-bound nitrogen allowances will be published in the Federal Register.
(b) Electric utility stationary gas turbines with a heat input at peak load greater than 107.2 gigajoules per hour (100 million Btu/hour) based on the lower heating value of the fuel fired shall comply with the provisions of Rule 260.332 (a)(1). (Rev. Effective 11/24/82)
(c) Stationary gas turbines with a heat input at peak load equal to or greater than 10.7 gigajoules per hour (10 million Btu/hour) but less than or equal to 107.2 gigajoules per hour (100 million Btu/hour) based on the lower heating value of the fuel fired, shall comply with the provisions of Rule 260.332(a)(2).
(d) Stationary gas turbines with a manufacturer's rated base load at ISO conditions of 30 megawatts or less except as provided in Section (b) shall comply with Subsection (a)(2) of this rule. (Rev. Effective 11/24/82)
(e) Stationary gas turbines with a heat input at peak load equal to or greater than 10.7 gigajoules per hour (10 million Btu/hour) but less than or equal to 107.2 gigajoules per hour (100 million Btu/hour) based on the lower heating value of the fuel fired and that have commenced construction prior to October 3, 1982 are exempt from Section (a) of this rule.
(f) Stationary gas turbines using water or steam injection for control of NOx emissions are exempt from Section (a) when ice fog is deemed a traffic hazard by the owner or operator of the gas turbine.
(g) Emergency gas turbines, military gas turbines for use in other than a garrison facility, military gas turbines installed for use as military training facilities, and fire fighting gas turbines are exempt from Section (a) of this rule.
(h) Stationary gas turbines engaged by manufacturers in research and development of equipment for both gas turbine emission control techniques and gas turbine efficiency improvements are exempt from Section (a) on a case-by-case basis as determined by the Administrator.
(i) Exemptions from the requirements of Section (a) of this rule will be granted on a case-by-case basis as determined by the Administrator in specific geographical areas where mandatory water restrictions are required by governmental agencies because of drought conditions. These exemptions will be allowed only while the mandatory water restrictions are in effect.
(j) Stationary gas turbines with a heat input at peak load greater than 107.2 gigajoules per hour that commenced construction, modification, or reconstruction between the dates of October 3, 1977, and January 27, 1982 and were required in the September 10, 1979, Federal Register (44 FR 52792) to comply with Rule 260.332(a)(1), except electric utility stationary gas turbines, are exempt from Section (a) of this rule. (Effective 11/24/82)
(k) Stationary gas turbines with a heat input greater than or equal to 10.7 gigajoules per hour (10 million Btu/hour) when fired with natural gas are exempt from Subsection (a)(2) of this rule when being fired with an emergency fuel. (Effective 11/24/82)
(l) Regenerative cycle gas turbines with a heat input less than or equal to 107.2 gigajoules per hour (100 million Btu/hour) are exempt from Section (a) of this rule. (Effective 11/24/82)
