MINISTRY OF FOREIGN AFFAIRS AND EUROPEAN INTEGRATION THE GOVERNMENT OF THE REPUBLIC OF CROATIA 3047 Pursuant to Article 24, paragraph 5 of the Environmental Protection Act (Official Gazette 82/94 and 128/99), the Government of the Republic of Croatia, at its session on 7 December 2006, adopted the following REGULATION ON TECHNICAL ENVIRONMENTAL STANDARDS FOR VOLATILE ORGANIC COMPOUND (VOC) EMISSIONS RESULTING FROM THE STORAGE AND DISTRIBUTION OF PETROL GENERAL PROVISIONS Article 1 This Regulation prescribes the technical environmental standards for petrol storage and loading installations at terminals and service stations and for mobile containers used for the transfer of petrol from one terminal to another or from a terminal to a service station, and the deadlines for their achievement. Article 2 The technical environmental standards referred to in Article 1 of this Regulation ensure the reduction of air pollution by emissions of volatile organic compounds and achievement of target values of the total annual loss of petrol at terminals, service stations and mobile containers. Article 3 For the purpose of this Regulation: 1. Petrol means any petroleum derivative, with or without additives, having a reid vapour pressure of 27.6 kilopascals or more, which is intended for use as a fuel for motor vehicles, except liquefied petroleum gas (LPG); 2.
