In 2014, significant changes were made to the civil defense legislation which require Gazprom Group companies operating gas trunk lines, gas distributing plants, and gas compressor stations to create and maintain local emergency notification systems (LNS) in a state of immediate readiness. The objective of this study is to analyze the current legislation and the peculiarities of practical application of the LNS-related rules. The subject of the study is the social relations that arise in the course of inspections by the Ministry of Emergency Situations of Russia and the issuance of improvement notices to gas transmission organizations. The author reviews some controversial issues related to the persistent negative judicial practice in commercial courts and general jurisdiction courts for subsidiaries of Gazprom PJSC. The civil defense legislation of the CIS countries (the Republic of Belarus and Kazakhstan) is systematically reviewed. This article proposes amendments to the current legislation that would specify certain features establishing LNSs at class I and II HPFs.
