RULE 1109 - EMISSIONS OF OXIDES OF NITROGEN FROM BOILERS AND PROCESS HEATERS IN PETROLEUM REFINERIES
(Adopted March 12, 1984)(Amended Dec. 7, 1984)((Invalidated Jan. 9, 1985)(Adopted November 1, 1985)(Amended August 5, 1988)
(A) the boiler/process heater is limited by permit condition to a lesser heat input, in which case the limiting condition shall be used as the maximum rated capacity; or
(B) the boiler/process heater is operated above the maximum design heat input, in which case the maximum operated rate shall be used at the maximum rated capacity.
(i) 0.14 pound (0.064 kilogram) of nitrogen oxides per million BTU of heat input when operated on gaseous fuel;
(ii) 0.308 pound (0.14 kilogram) of nitrogen oxides per million BTU of heat input when operated on liquid fuel;
(iii) the weighted average of the limits of subsections (b)(1)(A)(i) and (b)(1)A(ii), when operated concurrently on both liquid and gaseous fuel. For purpose of this rule, the nitrogen oxides formed in the fluid catalytic cracking unit regenerator shall be assumed to be from the burning of gaseous fuel.
(B) On December 31, 1992 and subsequent dates, the owner or operator of any petroleum refinery shall reduce emissions of nitrogen oxides from each unit subject to this rule so that:
(i) From December 31, 1992 until December 31, 1995, emissions from units which represent at least 36 percent of the total heat input are less than or equal to 0.03 pound per million BTU of heat input when firing at the maximum rated capacity, or as specified in the Alternative Emission Control Plan (AECP). Any unit not meeting the 0.03 pound per million limit shall not exceed its pound per million BTU limit specified in the Approved Control Plan for compliance with (b)(1)(A);
(ii) From December 31, 1995, emissions are less than or equal to 0.03 pound per million BTU of heat input when firing at the maximum rated capacity, or as specified in the Alternative Emission Control Plan (AECP).
(iii) For each unit firing at less than the maximum rated capacity, mass emissions of nitrogen oxides shall be less than or equal to the quantity that would occur at the applicable limit specified in (b)(1)(B)(i) and (b)(1)(B)(ii) at maximum rated capacity, or as specified in the AECP.
(iv) Alternative Emission Control Plan (AECP)
An owner/operator may achieve compliance with paragraphs (b)(1)(B)(i) and (b)(1)(B)(ii) by achieving equivalent nitrogen oxides emissions reductions obtained by alternative control methods provided the applicant submits an Alternative Emission Control Plan that is enforceable by the District and receives approval of the Plan in writing from the Executive Officer prior to implementation. The Alternative Emission Control Plan shall:
(I) Contain, as a minimum, all data, records, and other information necessary to determine eligibility for alternative emission control, including but not limited to:
a) A list of equipment subject to alternative emission control;
b) Daily hours of utilization for applicable equipment;
c) Estimated emission of nitrogen oxides for each operation;
d) Rated capacity; and
e) Historical and projected fuel use.
(II) Present the methodology for estimation of equivalency of emission reductions under the proposed Alternative Emission Control Plan as compared to either the emission reductions otherwise required by the rule or to actual emissions, whichever is less.
(III) Demonstrate that the permit units subject to the specified rule emission limitations are in compliance with or on an approved schedule for compliance with all applicable District rules.
Such plan shall contain as a minimum:
(A) A list of all units with the maximum rated capacity for each unit,
(B) A list of units to be controlled and the type of control to be applied for all such units, including a construction schedule,
(C) The method of calculation of the mass rate of nitrogen oxides emissions for each unit to achieve the refinery-wide emissions rates specified in subsection (b)(1), and
(D) On-site nitrogen oxide offsets from co-generation facilities may be incorporated in the plan.
(A) Within 180 days after completion of modifications, but no later than 1 month before any applicable compliance date for units which are to be modified with nitrogen oxides control equipment, and
(B) By December 1, 1986, for units which do not require modification.
(A) The owner or operator shall assign to each unit subject to this rule the maximum nitrogen oxides emissions rates (pounds or kilograms per million BTU heat input, expressed as nitrogen dioxide), while firing gaseous fuel or liquid fuel, which are allowable for that unit under the requirements of subsection (b)(1)(A).
(B) The owner or operator shall submit to the Executive Officer for approval a list, by the applicable compliance date, of the maximum allowable nitrogen oxides emissions rates identified in subsection (b)(6)(A) and a copy of the approved list shall be maintained for verification of continued compliance with the requirements of subsection (b)(2).
(C) Compliance with subsection (b)(1)(A) shall be determined by source testing any one unit subject to this rule, or additional units if required by the Executive Officer. No unit subject to this rule shall be operated at an emissions rate (pounds or kilograms per million BTU heat input, expressed as nitrogen dioxide) higher than that approved by the Executive Officer pursuant to subsection (b)(6)(B).
(A) Records shall be maintained and made accessible for a period of two years to the Executive Officer in a form and manner as specified by the Executive Officer.
(B) Compliance with subsection (b)(1)(B) shall be determined by source testing and/or in-stack nitrogen oxides monitor data or other data as specified for the equivalent verification system.
(c) Revision of Control Plan
A revised control plan may be submitted by the owner operator, along with any required permit applications. Such a plan shall adhere to the emissions limits and the final compliance dates of this rule. New units, including functionally identical replacement units, shall not be incorporated into the plan.
The requirements of Section (b) shall not apply to:
(e) Compliance Schedule
The owner or operator of a petroleum refinery having units subject to this rule shall fulfill the following increments of progress:
(A) By April 1, 1989, submit a revised control plan, pursuant to subsection (b)(3) of the rule.
(B) By September 1, 1989, submit required applications for permits to construct and operate.
(C) By December 31, 1992 demonstrate to the satisfaction of the Executive Officer compliance with (b)(1)(B)(i).
(A) By September 1, 1992, submit a revised control plan, pursuant to subsection (b)(3) of the rule.
(B) By February 1, 1993, submit required applications for permits to construct and operate.
(C) By December 31, 1995, demonstrate to the satisfaction of the Executive Officer compliance with (b)(1)(B)(ii).
