- 15 exchanger that captures heat from the afterburner or vapor
incinerator and an oven or furnace exhaust in order to reduce fuel consumption by an oven or the afterburner or vapor incinerator ; or (E ) A flare, afterburner, degassing unit, remediation unit, t hermal oxidizer, catalytic oxidizer or vapor incinerator process in which a fuel, including but not limited to natural gas, propane, butane or liquefied petroleum gas, is mixed with air toxics, VOCs , landfill gas, digester gas or other combustible vapors p rior to incineration
in the unit

, in order to maintain vapor concentration above the upper explosion limit or above a manufacturer specified limit in order to maintain combustion or temperature in the unit. This exemption does not apply to a burner with a separate fuel line used to heat up or maintain temperature of a unit or incinerate air toxics, VOCs or other combustible vapors in a gas stream moving past the
burner flame. (4 ) New afterburners, d egassing units, thermal oxidizers, catalytic oxidizers,

- 16 (h) Technology Assessment (1) On or before December 7, 2015 , the Executive Officer shall conduct a technology assessment and shall report to the Governing Board on the availability of burner systems and units for processes with NOx emissions of one po und per day or less.

(i ) Mitigation Fee Compliance Option (1) An owner or operator of a unit with emissions of more than 1 pound per day may elect to delay the applicab le compliance date in Table 2 of paragraph (c)(1) or (c)(4) three years by submitting an alternate compliance plan and paying an emissions mitigation fee to the District in lieu of meeting the applicable NOx emission limit in Table 1. (2) Compliance Demonstration An owner or operator of a unit electing to comply with the mitigation fee

com pliance option shall: (A) Submit an alternate compliance plan and pay the mitigation fee to

t he Executive Officer at least 15 0 days prior to the applicable compliance date in Table 2 of paragraph (c)(1) or (c)(4), and (B) Maintain on

- site a copy of verifi cation of mitigation fee payment and AQMD approval of the alternate compliance plan that shall be made available upon request to AQMD staff. (3) Plan Submittal The alternate compliance plan submitted pursuant to paragraphs (i)(1) and (i)(2) shall include: (A) A completed AQMD Form 400A with company name, AQMD Facility ID, identification that application is for a compliance plan (section 7 of form), and identification that request is for the Rule 1147 mitigation fee compliance option (section 9 of form); (B) Attached documentation of unit fuel use for previous 5 years, description of weekly operating schedule

, unit permit ID, unit heat rating (Btu/hour), and fee calculation; (C) F iling fee payment; andRule 1147 (Cont.) (Adopted December 5, 2008) (Amended September 9, 2011)

- 17 (D) M itiga tion fee payment as calculated by Equation 1.
Equation 1:

MF = R X ( 3 years ) X ( L 1 – L 0 ) X ( AF ) X ( k )

Where,
MF = Mitigation fee, $

R = Fee Rate = $12.50 per pound ( $6.25 per pound for a small business with 10 or fewer employees and gross annual receipts of $500,000 or less)

L 1 = Default NOx emission factor, 0.136 lbs of NOx/mmBtu for natural gas and LPG, and 0.160 lb/mmBtu for fuel oils

L 0 = Applicable NOx emission limit specified in Table 1 in lbs/mmBtu

AF = Annual average fuel usage of unit for previous 5 years, mmscf/yr for natural ga s or gallons for liquid fuel

k = unit conversion for cubic feet of natural gas to Btu = 1,050 Btu/scf, 95,500 Btu/gallon for LPG, and 138,700 Btu/gallon for fuel oil
