Proposed Amended Rule 1147 - NOx Reductions From Miscellaneous Sources

SCAQMD staff is proposing to amend Rule 1147 - NOx Reductions from Miscellaneous Sources, in order to resolve Rule 1147 compliance issues that have been raised by stakeholders. If adopted, PAR 1147 would: 1) change the NOx emission limit for low temperature (<1,200 degrees Fahrenheit) ovens and other units with a heat input rating of less than 325,000 Btu/hour from 30 parts per million to 60 ppm; 2) change the NOx emission limit for low temp afterburners, burn-off ovens, incinerators, and related equipment from 30 ppm to 60 ppm; 3) change the compliance date for small in-use units (NOx emissions of one pound per day or less) from a schedule based on a 20 year lifetime to a 35 year lifetime or unit the units are replaced, retrofit or relocated; 4) change the compliance date for heated process tanks from a schedule based on a 15 year to 20 year lifetime to when the units are replaced, retrofit or relocated; 5) add a testing exemption for ultra-low NOx infrared burners; 6) clarify an exemption for food ovens; and 7) clarify an exemption for flare type systems. Some facilities that may be affected by PAR 1147 identified on lists complied by the DTSC per CA Government code 65962.5. If implemented, PAR 1147 is expected to result in NOx emission reductions foregone of up to 0.9 tons per day in 2017. However, the emission reductions foregone will be eventually recaptured because the existing units will be regularly replaced and upgraded over time.
