The Industrial Pollution Control (Prescribed Processes and Substances) Regulations (Northern Ireland) 1998

Part C

The following processes unless carried on in relation to and as part of any Part A or Part B process—

(a) burning any fuel in a boiler or furnace with a net rated thermal input of not less than 20 megawatts, but less than 50 megawatts;

(b) burning any fuel in a gas turbine or compression ignition engine with a net rated thermal input of not less than 20 megawatts, but less than 50 megawatts;

(c) burning as fuel, in an appliance with a net rated thermal input of less than 3 megawatts, waste oil or recovered oil;

(d) burning in an appliance with a net rated thermal input of less than 3 megawatts solid fuel which has been manufactured from waste by a process involving the application of heat;

(e) burning, in any appliance, fuel manufactured from, or including, waste (other than waste oil or recovered oil or such fuel as is mentioned in paragraph (d)) if the appliance has a net rated thermal input of less than 3 megawatts but at least 0.4 megawatts or is used together with (whether or not it is operated simultaneously with) other appliances which each have a net rated thermal input of less than 3 megawatts and the aggregate net rated thermal input of all the appliances is at least 0.4 megawatts.

In paragraph (b) of Part A and paragraph (e) of Part C, “fuel” does not include gas produced by biological degradation of waste; and for the purposes of this Section—

• “net rated thermal input” is the rate at which fuel can be burned at the maximum continuous rating of the appliance multiplied by the net calorific value of the fuel and expressed as megawatts thermal; and

• “waste oil” means any mineral based lubricating or industrial oil which has become unfit for the use for which it was intended and, in particular, used combustion engine oil, gearbox oil, mineral lubricating oil, oil for turbines, hydraulic oil; and

• “recovered oil” means waste oil which has been processed before being used.
