If any standards newly formulated (revised) or issued by the State or local governments are stricter than the emission limits specified in Table 3 of the Emission Standard of Air Pollutants for Boilers(DB 44/765-2019), such newly formulated (revised) or issued standards should prevail.

　　3.2 Enterprises and institutions with boilers burning biomass moulding fuel and gas-fired boilers in use should take effective measures to ensure that they can meet the special emission limits of air pollutants within the specified time.
