Sch 5 para 2 Conversion of a greenhouse gas emissions permit
(1) Where a greenhouse gas emissions permit has been granted in respect of an installation that is an Article 27 installation, the regulator must vary the greenhouse gas emissions permit (with effect from a date to be included in the permit) so that the provisions of the permit are replaced by provisions that satisfy the requirements of paragraph 3. (2) When a permit is varied under sub-paragraph (1)— (a) the regulator may make only such variations as appear to the regulator to be necessary in consequence of the installation being an Article 27 installation; but (b) that is without prejudice to the duty to vary the permit in accordance with regulation 88(2) or (4) . (3) A variation of a permit under this paragraph does not affect any obligations of the operator under the permit in respect of emissions arising prior to 1st January 2021 .
