Document Description
Note: Review Per Lead SCAQMD staff is proposing to amend Rule 1111 in order to resolve compliance issues that have been raised by stakeholders. If adopted, PAR1111 would increase the mitigation fee from $200 for each non-compliant condensing furnace and $150 each for all other non-compliant furnaces regulated under this rule to $400 for all non-compliant units and extend the dates for complying with the NOx limit for the following equipment categories: 1) condensing furnaces from April 1, 2018, to October 1, 2019; 2) non-condensing furnaces from October 1, 2018, to October 1, 2019; 3) weatherized furnaces from October 1, 2019, to October 1, 2020; and 4) mobile home furnaces from October 1, 2021, to Oct 1, 2022. If the compliance dates are extended, PAR 1111 is expected to result in foregone NOx emissions reductions of 0.07 to 0.069 tons per day in 2018, 0.26 to 0.33 tons per day in 2023, and 0.26 to 0.33 tons per day in 2031, all of which exceed the SCAQMD's regional air quality CEQA significance threshold for NOx during operation. The analysis of PAR 1111 in the draft SEA identified potentially significant adverse air quality impacts. However, the NOx emissions reductions foregone will eventually be achieved b/c existing furnaces will be regularly replaced and upgraded over time with cleaner units. In addition, the mitigation fee will generate emission reductions from the projects to be financed with the fee. No facilities that manufacture equipment that would be subject to PAR 1111 have been identified on lists compiled by DTSC per Gov Code Section 65962.5.
