Technical regulations requirements for the safety of gas supply systems. Technical regulations on the safety of gas distribution and gas consumption networks

HISTORY OF THE ISSUE December 2005 - OJSC Giproniigaz (co-executor - Scientific and Technical Center "Industrial Safety"), under the State contract with the Ministry of Industry and Energy of Russia, on the basis of the Government program for the development of technical regulations (1421-r of the year), developed a draft Federal Law - special technical regulations"About safety production processes and gas supply systems." During public discussions, more than 500 proposals and comments were received from 22 organizations, about 70% of which were accepted. In particular, new proposals and comments from Rostekhnadzor, the Ministry of Regional Development of the Russian Federation, the Ministry of Emergency Situations of the Russian Federation, OJSC Gazprom, OJSC Gazpromregiongaz, OJSC Promgaz were taken into account. On November 29, 2006, the Expert Commission of the Ministry of Industry and Energy recommended submitting the draft technical regulations approved by it to the State Duma Federal Assembly RF for consideration and adoption in the prescribed manner. In amendments were made to the federal law “On technical regulation”, administrative reform and the Government program for the development of technical regulations was adjusted, according to which it was decided to adopt technical regulations in the form of a Decree of the Government of the Russian Federation. In June 2008, as a result of many years of requests from OJSC Giproniigaz, the old name of the draft technical regulations was changed to the new name “On the safety of gas distribution and gas consumption networks.”

HISTORY OF THE ISSUE By August 2008, the Ministry of Energy of the Russian Federation, together with OJSC Giproniigaz, prepared new option draft technical regulations “On the safety of gas distribution and gas consumption networks” and began the next round of public discussion and approvals, which was completed only in August 2010. In accordance with the current legislation, the Expert Commission of the Ministry of Industry and Trade of Russia on August 11, 2010 at its meeting reviewed the draft technical regulations and found that the draft Resolution of the Government of the Russian Federation “On approval of technical regulations on the safety of gas distribution and gas consumption networks” submitted for examination complies with legislative and other regulatory standards legal acts of the Russian Federation in the field of technical regulation, the interests of the national economy, the development of the material and technical base and the level of scientific and technical development, as well as international norms and rules. On October 25, 2010, the draft technical regulation on the safety of gas distribution and gas consumption networks was considered at a meeting of the Presidium of the Government of the Russian Federation and on October 29, 2010, the Chairman of the Government of the Russian Federation V.V. Putin signed Resolution 870 “On approval of the technical regulation on the safety of gas distribution and gas consumption networks.” In just 5 years of work on the draft technical regulations, about 700 proposals and comments were officially received, of which approximately 75% were accepted by the developers. Over the years, more than 70 versions (editions) of technical regulations have been prepared.

Federal Law 184-FZ “On Technical Regulation” Federal Law 116-FZ “On industrial safety hazardous production facilities" Federal Law 384-FZ "Technical Regulations on the Safety of Buildings and Structures" Technical Regulations on the Safety of Gas Distribution and Gas Consumption Networks (approved by Decree of the Government of the Russian Federation of October 29, 2010 870) Legislative framework of the technical regulations

About the ideology of the draft technical regulation YES The technical regulation is a state regulatory legal act: - having as its goals - ensuring the protection of society from potentially dangerous business that may pose a threat to the life, health, property of the population; threat to the environment; the danger of misleading purchasers of products and services; as well as ensuring energy efficiency; – establishing the minimum necessary administrative barriers for a potentially dangerous business, determined taking into account the degree of risk of harm to third parties as a result of the business carrying out its activities. NO Technical regulations are not corporate regulatory and technical a document justifying, and often lobbying for, specific design and design solutions, materials, technical and technological devices.

On the need to take into account international experience when developing regulations 184-FZ “On Technical Regulation”, Article 7, paragraph 8: “International standards should be used in whole or in part as the basis for the development of draft technical regulations, except in cases where international standards or their sections were would be ineffective or unsuitable for achieving the goals established by Article 6 of this Federal Law, including due to climate and geographical features Russian Federation, technical and (or) technological features.”

Positive and negative experience (65 years) of mass gasification according to domestic regulatory documents based on excessive (mostly prohibitive) regulation of requirements for design, construction and operation, including a planned preventive maintenance system; - Gas distribution and gas consumption networks that have been built and are in operation are significant in scale and age: for example, more than km of gas pipelines (only about 25% are polyethylene) and near gas control points; - The impossibility of a one-time revolutionary change in the requirements for gas distribution and gas consumption networks in isolation from the requirements for other engineering infrastructure facilities in Russia; - Formed under conditions of excessive regulation qualification level and the mentality of engineering and technical personnel; - Not good high quality natural gas supplied to the Russian market. UNCONDITIONAL ORIENTATION TO BEST INTERNATIONAL EXPERIENCE WHILE ENSUREING A PLANNED AND EVOLUTIONARY CONVERGENCE OF DOMESTIC AND FOREIGN REGULATORY REQUIREMENTS. On accounting for technological and technical features Russian Federation
