The San Joaquin Valley Air Pollution Control District (SJVAPCD) will hold a public hearing on October 15 to consider the adoption of proposed amendments to District Rule 4905, a point-of-sale rule that limits NOx emissions from Natural Gas-Fired, Fan-Type Central Furnaces. Natural gas furnaces are typically used to provide heat to residential and commercial properties.
The previous amendment to this rule included lowering the NOx emission limit from 40 ng/J to 14 ng/J and allowing the sale of non-compliant units during the initial 36-month implementation period with a fee payment for each non-compliant unit. Manufacturers are now able to meet the 14 ng/J NOx limit for non-weatherized condensing and non-condensing units, including dual-fuel units. However, due to supply chain interruptions, labor shortages, and travel restrictions, COVID-19 has impacted the industry's ability to develop compliant weatherized units by the September 30, 2020 deadline. The proposed amendments would extend mitigation fee period for weatherized furnaces to September 30, 2021 (including no change to the mitigation fee amount), allowing time for SJVAPCD to work closely with South Coast Air Quality Management District to address concerns raised by furnace manufacturers.
The proposed rule is available on the SJVAPCD website, and the public comment period will extent until September 29. The Governing Board will hold a public hearing on the proposed rule on October 15.
