AQMD Rule 1147 Proposed NOx Rule Amendments

Navigating SCAQMD Rule 1147: A Comprehensive Guide

About SCAQMD

The South Coast Air Quality Management District, commonly referred to as South Coast AQMD, was established in 1976. It serves as the organization responsible for overseeing and controlling sources of stationary air pollution in the South Coast Air Basin and the Coachella Valley area of the Salton Sea Air Basin in Southern California. SCAQMD develops, adopts, and implements an Air Quality Management Plan for bringing the area into compliance with the clean air standards established by national and state governmental legislation.

About Rule 1147

Rule 1147 specifically pertains to “NOx and CO Emissions from Miscellaneous Sources.” NOx refers to nitrogen oxides, which are pollutants produced from combustion processes, and CO refers to carbon monoxide, another harmful emission produced from incomplete combustion. The regulation is designed to restrict the release of nitrogen oxides (NOx) and carbon monoxide (CO) from different sources that might not be subject to other existing rules. These sources could encompass small-scale industrial procedures, commercial endeavors, or other activities that add to the contamination of the air in the area.

Things to do under Rule 1147

• Keep Records: Manufacturers and distributors must keep records of product recipes, testing for VOC content, and other important details. This allows regulatory bodies to confirm that they are following the regulations. Furthermore, they might need to regularly report data on VOC emissions and compliance to ensure that they continue to follow the regulations consistently.
• Product Formulation Review: Manufacturers and formulators are obligated to provide detailed information regarding their product compositions to ensure adherence to VOC (Volatile Organic Compound) limits.
• Emission Testing: Regulatory authorities might carry out emissions tests to confirm the VOC content of products. Random sampling and testing aid in identifying products that do not meet compliance standards.
• Compliance Assistance: SCAQMD (South Coast Air Quality Management District) extends guidance and assistance to manufacturers and businesses to help them grasp and satisfy the requirements of the regulation.
• Penalties and Fines: Failure to comply with Rule 1147 could lead to penalties and fines. SCAQMD possesses the authority to take legal measures against those who violate the rule to ensure adherence.
• Require Fuel Meter: Remove the requirements for installation of non-resettable totalizing fuel meters if the operator intends to comply with the Rule 1147 NOx emission limits in parts per million (ppm), but still require the fuel meters if the operator intends to comply with the NOx emission limits in pounds per million British Thermal Units (lb/mmBTU).

SCAQMD Rule 1147 Frequently Asked Questions (FAQs)

• What if my current NOx emissions are lower than the rule limit?

If your equipment meets the rule limits, you must demonstrate compliance with a source test performed by a certified source testing company on or before the compliance date. Before conducting the test, a source test protocol must be submitted to the District for approval at least 90 days prior to the scheduled test date. The source test report shall be maintained on-site for 10 years and made available to District personnel upon request.

• How do I know what my current NOx emissions are?

You can measure NOx emissions using a portable analyzer to get an idea of whether the NOx emissions already meet the rule limits. Southern California Gas Company (SoCalGas®) has technicians that may be able to assist you with this testing. If your exhaust gas oxygen level is high, specific source testing may be required.

• How do I determine if my equipment is subject to Rule 1147?

Unless specifically exempt from the rule, any combustion equipment that is not exempt from a permit and is not subject to a source-specific NOx limit is subject to 1147. If uncertain, you can contact SCAQMD Small Business Assistance Office at (800) 388-2121 or ask for SCAQMD Compliance at (909) 396-2000 to be connected to the team that is responsible for inspecting your business.
