  "heading": "Permits: emission limit values",
  "text": "(1) All permits for operating a large combustion plant which have been granted before 7 January 2013, or for which a complete application was submitted before that date, provided that such plants were in operation not later than 7 January 2014 must include conditions ensuring that emissions into the air from these plants do not exceed the emission limit values set out in Chapter 1 of Part 3 of this schedule.\n(2) All permits for operating a large combustion plant other than those described in sub-paragraph (1) must include conditions ensuring that emissions into the air from these plants do not exceed the emission limit values set out in Chapter 2 of Part 3 of this schedule.\n(3) Emission limit values and minimum rates of desulphurisation apply to the emissions of each common stack in relation to the total rated thermal input of the entire large combustion plant.\n(4) Where Part 3 of this schedule provides that emission limit values may be applied for a part of a large combustion plant with a limited number of operating hours, those limit values apply to the emissions of that part of the plant, but must be set in relation to the total rated thermal input of the entire combustion plant.\n(5) Where a large combustion plant is extended, the emission limit values set out in Chapter 2 of Part 3 of this schedule—\n(a) apply to the extended part of the plant affected by the change,\n(b) must be set in relation to the total rated thermal input of the entire combustion plant.\n(6) Sub-paragraph (7) applies where there is an extension to a large combustion plant that—\n(a) may have consequences for the environment, and\n(b) affects a part of the plant with a rated thermal input of 50 MW or more.\n(7) Where this sub-paragraph applies, the emission limit values as set out in Chapter 2 of Part 3 of this schedule apply to the part of the plant referred to in sub-paragraph (5) which has changed in relation to the total rated thermal input of the entire combustion plant.",
