80. (Replaced, O.C. 501-2011)Standards for preventing the contamination of the environment: Any new tank with a capacity of 250 m3 or more, designed for the storage of organic compounds having on actual vapour pressure comprised between 10 and 75 kPa under normal storage conditions must:
(a) be equipped with a floating roof or with an equivalent device as regards the level of hydrocarbon losses by evaporation as computed for a tank of the same size equipped with a floating roof by the method described in Bulletin 2517 (June 1962) of the American Petroleum Institute entitled API Bulletin on Evaporation Loss from Floating Roof Tanks; and
(b) be of the welded type and painted in a light colour.
Subparagraph a of the first paragraph also applies, from 1 July 1983 to existing tanks serving for storing organic compounds having an actual pressure vapour comprised between 10 and 75 kPa under normal storage conditions with a capacity of 1 500 m3 or more and whose annual flow rate in the case of tank connected to the operation of an ore refinery is of 4 500 m3 and more.
