This 2013 government notice from the South African Department of Environmental Affairs declares small boilers as controlled emitters under the National Environmental Management: Air Quality Act, 2004. It establishes specific emission standards for particulate matter and sulphur dioxide across various fuel types, defines compliance timeframes for new and existing boilers, and mandates annual emissions reporting to air quality officers.

• The Minister of Water and Environmental Affairs has officially declared a 'small boiler' as a controlled emitter and established corresponding emission standards under sections 23(1) and 24 of the National Environmental Management: Air Quality Act, 2004.
• A 'small boiler' is defined as any boiler with a design capacity of at least 10MW but less than 50MW net heat input per unit, calculated based on the lower calorific value used.
• Compliance deadlines differ based on the age of the equipment: new small boilers (manufactured after the notice date) must comply immediately upon publication, while existing small boilers (manufactured before the notice date) are granted a 5-year window for compliance.
• The notice sets specific limits on smoke emissions during non-normal operations: black smoke is limited to 20 minutes during start-up, and dark smoke is limited during soot blowing and abnormal conditions.
• Boiler operators are required to submit at least one emissions report annually to the relevant air quality officer, with the first report due within 12 months of the notice taking effect. Measurement records must be maintained for at least five years.
• Emission standards are categorized by fuel type, including solid fuel (excluding biomass), liquid fuel, gaseous fuel (natural gas and LPG), process gas, and solid biomass. In cases of co-feeding with two or more fuels, the standards for the main fuel apply.
• Pollutant concentrations must be reported as the average of at least three measurements, each taken over a minimum sample period of 60 minutes under normal operating conditions.
