  "long_title": "The discharge of certain noxious or offensive gases from certain types of works is subject to control under the Alkali, and c. Works Regulation Act 1906 (“the Act of 1906”). Article 25(9) of the Clean Air (Northern Ireland) Order 1981 empowers the Department to make orders amending or extending both the list of gases and the list of works in the Act of 1906. The existing list of such gases is set out in section 27(1) of that Act, as extended and amended by the Alkali, and c. Works Order (Northern Ireland) 1987, and the existing list of works is set out in the First Schedule to that Act, also as extended and amended by that order. This order further extends and amends both these lists, and revokes the order of 1987.",
