The San Joaquin Valley Air Pollution Control District (SJVAPCD) is implementing amendments to Rule 4905 - Natural Gas-Fired, Fan-Type Central Furnaces set to pass on June 21, 2018. Rule 4905 applies to manufacturers who sell or distribute natural gas-fired, fan-type central furnaces < 175,000 BTU/hr and combination heating/cooling units < 65,000 BTU/hr. Currently, Rule 4905 prohibits the sale of a central furnace with a NOx emission limit greater than 14 ng/Joule of heat output.

In Lieu of meeting the aforementioned NOx limit, the proposed amendments allow manufacturers to pay an emissions fee and meet a certified NOx emission limit of 40 ng/J. Manufacturers are required to pay $290 for each condensing furnace and $225 for each other type of furnace sold before the Phase 1 emission fee start date. After the emission fee start date, manufacturers will have to pay additional fees for each unit sold or distributed in accordance with Table 3 of Rule 4905. In addition, manufacturers who elect the emission fee payment option must submit a compliance plan to the SJVAPCD. The compliance plan must identify which types of furnaces will be sold in each 12-month compliance period and estimate the quantity of units that will be sold. Manufacturers and distributors in the San Joaquin Valley should be aware of compliance plan and emissions fee due dates.
