Proposed Amended Rule (PAR) 1111 – Reduction of NOx Emissions from Natural Gas-Fired Furnaces, (continued)

Proposed Amended Rule (PAR) 1111 – Reduction of NOx Emissions from Natural Gas-Fired Furnaces, (continued)

Continued Title: and PAR 1121 – Reduction of NOx Emissions from Small Natural Gas-Fired Water Heaters PAR 1111 proposes to: 1) expand rule applicability to include previously unregulated wall furnaces, floor furnaces, and commercial furnaces with a rated heat input capacity up to 2,000,000 British Thermal Units per hour (Btu/hr); and 2) establish four categories for the applicable units, each with zero-emission limits for new installations based on future effective dates. PAR 1121 proposes to include zero-emission limits for new installations based on future effective dates. PAR 1111 and PAR 1121 also propose to: 1) differentiate the zero-emission compliance dates for units installed in new or existing buildings; 2) provide alternative compliance options for emergency replacement and installations requiring specific type of construction; 3) introduce labeling and reporting requirements; 4) provide an exemption from zero-emission requirements for mobile homes in a master-metered mobile home park; and 5) update and clarify rule language. Replacement of furnaces and water heaters are expected to occur at the end of the existing equipment’s useful life although some replacements could occur prior to the end of useful life with the availability of incentive funding. Upon full implementation, emission reductions of oxides of nitrogen (NOx) up to 7.7 tons per day by 2055 for PAR 1111, and 2.3 tons per day by 2045 for PAR 1121, are expected. The Draft SEA concluded that significant and unavoidable adverse environmental impacts may occur for the topics of air quality due to construction activities, and energy due to increase in electricity and natural gas demand (natural gas used in the short term to produce electricity until renewable energy resources can supply the electricity demand). No other significant adverse impacts were identified. Facilities and residences with equipment subject to the proposed project may be identified on lists compiled by the California Department of Toxic Substances Control per Government Code Section 65962.5. However, implementation of PAR 1111 and PAR 1121 is not expected to alter the status of the facilities and other locations on the lists.
