Identification of gas consumption networks during registration as HPO

Since September 1, 2016, the procedure for identifying gas distribution and gas consumption networks as HIFs has changed.

So, among the number of hazardous production facilities now do not apply gas distribution networks and gas consumption networks operating under pressure of natural gas or liquefied hydrocarbon gas up to 0.005 MPa inclusive (paragraph 27 of Appendix No. 1 to Federal Law 116).

The principle of determining and the procedure for assigning a hazard class to gas consumption and gas distribution networks has also changed. In particular, paragraph 1 of Appendix 2 to Federal Law 116 specifies that “hazard classes of HIFs specified in paragraphs 2 (facilities for the storage, destruction of chemical weapons and HIFs of special chemistry), 3 (objects for drilling and production of oil, gas and gas condensate) and 4 (gas networks) of this annex shall be established in accordance with the criteria specified in paragraphs 2, 3 and 4 of this annex.”

This amendment is very important for the unambiguous classification of gas consumption and gas distribution networks depending on the degree of danger. Previously, the owners of HIFs of this type, when determining the hazard class, took into account the amount of the hazardous substance and referred to Table 2 of Appendix No. 2 to Federal Law 116. In this regard, they mistakenly believed that hazard class 4 could be assigned to gas networks. AT new edition Federal Law No. 116 excludes such confusion.

Namely, the updated version of clause 4 of Appendix 2 to Federal Law No. 116 states:

"four. For gas distribution stations, gas distribution networks and gas consumption networks, the following hazard classes are established:

1) Hazard class II - for HIFs intended for transportation of natural gas under pressure over 1.2 MPa or liquefied hydrocarbon gas under pressure over 1.6 MPa;

2) III hazard class- for hazardous production facilities intended for the transportation of natural gas under pressure over 0.005 MPa to 1.2 MPa inclusive or liquefied hydrocarbon gas under pressure over 0.005 MPa up to 1.6 MPa inclusive.

Information on the operating pressure parameters in gas consumption and gas distribution networks, which is the criteria for classifying these networks as HIFs and a specific hazard class, can be found by the owner of a hazardous facility in documents such as:

• Technical documentation for elements of gas networks (gas pipelines, boilers and other gas-using equipment).
• Information characterizing a hazardous production facility.
• The act of commissioning HIF, etc.

Gas distribution networks and gas consumption networks, pressurized with natural gas or liquefied petroleum gas over 0.005 MPa remain supervised and are subject to registration as HBOs. At the same time, these facilities include external and internal gas pipelines of the organization, sites of gasified boiler houses and their equipment, gas distribution equipment, as well as the gas part of gas-consuming equipment and installations, gas turbines, process lines in buildings and structures on the territory of the organization.

According to the Federal Law No. 116-FZ of July 21, 1997 “On industrial safety ...”, registration with Rostekhnadzor of gas consumption networks belonging to the HIF category is mandatory. However, the HIF Registration Certificate is only the first step towards the legal operation of hazardous objects of this type. Each HIF owner must have a set of mandatory regulatory, technical and permitting documents, a list of which we will provide in this article.

What documents are needed for the legal operation of gas consumption networks

Each organization operating gas consumption networks must develop and / or obtain the following regulatory, technical and permitting documents:

1. Certificate of registration of HPO- a document confirming the entry of information about the gas consumption network into the state register of HIFs. It is accompanied by the Accounting Cards agreed with the territorial department of Rostekhnadzor and Information characterizing the HIF.

The need to register HIFs with Rostekhnadzor is regulated by Federal Law No. 116-FZ dated July 21, 1997. “On industrial safety…”, as well as the regulatory legal acts created on its basis.

2. Rostekhnadzor license for the operation of explosive and fire hazardous and chemically hazardous production facilities of I, II and III hazard classes - the main permit document that gives the right to operate the gas consumption network legally.

Receive Rostekhnadzor licenses for the operation of HIFs (gas consumption networks) oblige:

• Federal Law No. 99 dated 04.03.2011 About Licensing certain types activities".
• Federal Law No. 116 of July 21, 1997 "On industrial safety ...".
• Decree of the Government of the Russian Federation No. 492 dated June 10, 2013 No. "On Licensing the Operation of Explosive and Fire Hazardous and Chemically Hazardous Industrial Facilities of I, II and III Hazard Classes".

When developing the Regulations on production control for gas consumption networks, the requirements of such regulations as:

• Order of Rostekhnadzor No. 542 dated November 15, 2013 “On Approval of Federal Norms and Rules in the Field of Industrial Safety “Safety Rules for Gas Distribution and Gas Consumption Networks”.
• Decree of the Government of the Russian Federation No. 870 dated October 29, 2010 No. "On Approval of the Technical Regulations on the Safety of Gas Distribution and Gas Consumption Networks".
• Decree of the Government of the Russian Federation No. 263 of March 10, 1999 "On the organization and implementation of production control over compliance with industrial safety requirements at HIFs."

The procedure for conducting a technical investigation into the causes of incidents at HIFs, the main points of which are reflected in the document, is enshrined in Rostechnadzor Order No. 480 dated 19.08.2011. Please note that in accordance with paragraph 32 of the "Procedure for the technical investigation of the causes of accidents, incidents ..." The Regulation on the investigation of incidents is approved by the operating organization and is coordinated with the territorial department of Rostekhnadzor.

5. Plan of measures for localization and liquidation of consequences of accidents at HIFs- a mandatory regulatory and technical document, which is being developed for fire-explosive and chemically hazardous production facilities of classes I, II and III. The gas consumption network belongs to this category.

• The need for and procedure for developing an Action Plan are determined by:
• Government Decree No. 730 dated 26.08.2013 "On approval of the Regulations on the development of action plans for the localization and elimination of the consequences of accidents at hazardous production facilities."
• By order of Rostekhnadzor No. 781 dated December 26, 2012. "On approval of recommendations for the development of plans for the localization and elimination of accidents at explosive and chemically hazardous production facilities."

5.1. Agreement with a professional emergency rescue team(ASF) for the provision of services for the localization and elimination of the consequences of accidents at HIFs. As a rule, the DFA is selected according to the location of the object. This is done so that rescuers can quickly arrive at the scene of the accident and eliminate its consequences in a timely manner.

6. Safety data sheet of a hazardous facility- warning document emergencies, reducing the risk of man-made emergencies at facilities that use, produce, process, store or transport explosive and chemically hazardous substances. In gas consumption networks, an explosive and flammable substance (gas) is used and transported, so the owners of such facilities need to develop a Safety Data Sheet. The document is closely related to the action plan for localization and elimination of the consequences of accidents at HIFs.

The document is developed once every 5 years, provided that there are no changes in the composition of the HPF and its characteristics. After the development of the Safety Data Sheet, it is agreed with the Main Directorate of the Ministry of Emergency Situations of Russia for the constituent entity of the Russian Federation, and after approval, it is approved by the owner of the facility.

7. Compulsory insurance policy civil liability the owner of a hazardous facility for causing harm as a result of an accident at a hazardous facility.

The need for an agreement to HIF insurance, in particular, gas consumption networks, is regulated by:

• Federal Law No. 225-FZ of July 27, 2010 No. "On Compulsory Insurance of Civil Liability of the Owner of a Hazardous Object...".
• Federal Law No. 116-FZ of July 21, 1997 "On Industrial Safety..." (Article 15).

8. Protocols of attestation (knowledge testing) on ​​industrial safety, certified by the attestation commission of Rostekhnadzor, for at least 2 employees of the organization.

For enterprises operating gas consumption networks, it is necessary to certify at least the head (deputy head) and the person responsible for the gas economy (for the safety of the operation of gas consumption networks), in directions A1 "Fundamentals of industrial safety" and B7.1. "Operation of gas distribution and gas consumption systems".

The need for industrial safety certification is determined by the requirements of:

• Federal Law No. 116-FZ of July 21, 1997 "On industrial safety ...".
• Order of Rostekhnadzor No. 37 dated 29.01.2007 "On the procedure for training and certification of specialists from organizations supervised by the Federal Service for Environmental, Technological and Nuclear Supervision."

The need for an Expertise is regulated by:

• Federal Law No. 116-FZ of July 21, 1997 "On industrial safety ...".
• Order of Rostekhnadzor No. 538 dated November 14, 2013. “On approval of federal norms and rules in the field of industrial safety “Rules for the examination of industrial safety” and other regulatory legal acts.

Supervision of gas consumption networks

Supervision of gas consumption networks is carried out by the territorial department of Rostekhnadzor at the location of the facility. Gas consumption networks belong to the 3rd hazard class (Appendix 2 to the Federal Law No. 116), therefore, scheduled inspections in relation to these HIFs are carried out no more than once every three years(Clause 5.1. Article 16 of the Federal Law No. 116).

In the course of supervisory activities, Rostekhnadzor inspectors will check that the organization has the above documents, technical documentation equipment, conduct a visual inspection of technical devices and buildings (structures) for their serviceability and operational safety. An analysis will be made of compliance with the requirements of regulations in the field of industrial safety, the requirements of the Technical Regulations on the safety of gas distribution and gas consumption networks (approved by Decree of the Government of the Russian Federation No. 870 of October 29, 2010) and the Safety Rules for gas distribution and gas consumption networks (approved by Order of Rostekhnadzor No. 542 dated November 15, 2013).

Thus, according to Section II of the Rules for the Safety of Gas Distribution and Gas Consumption Networks and Section VI of the Technical Regulations on the Safety of Gas Distribution and Gas Consumption Networks, an organization operating gas consumption networks must:

• carry out a set of measures, including monitoring, maintenance and repair of gas consumption networks, ensuring the maintenance of gas consumption networks in good and safe condition;
• perform maintenance, repair and emergency dispatch support of gas consumption networks;
• store design and as-built documentation throughout the life of the HIF, etc.
