DECLARATION
Ministry of Industry and Trade
of 14 August 1995
on states of emergency in the gas industry and the dispatching management of the gas system
The Ministry of Industry and Trade pursuant to § 45 (6), having regard to § 12 (2) and (7) and § 13 (7) of Act No 222 / 1994 Coll., on the Terms and Conditions of Business and on the Performance of State Administration in the Energy Sector and on State Energy Inspection ("the Act '), provides:
Subject matter
This decree regulates the procedure for the creation and removal of the consequences of emergency situations for the gas industry (hereinafter referred to as "emergency situations') and sets out the scope and manner of limiting the consumption of gas in emergency states and the rules of dispatching management (hereinafter referred to as the" Dispatching Regulations') of the gas system.
Breakdown of emergencies
(1) The state of emergency, according to the cause of its occurrence, is subdivided into foreseeable and unpredictable states.
(2) Predictable situations are emergencies where the cause of creation is known in advance and cannot be removed by the commonly available means of the holder of the state authorisation.
(3) Unforeseeable situations are those which arise from disturbances or accidents on gas production or distribution facilities and which cannot be predicted.
Consequences of emergencies
(1) As a result of emergencies, the limitation of gas consumption is as follows:
(a) limiting the sampling stages; the limiting demand level represents a certain percentage by which the supply of gas to customers in the category of wholesale gas collector for production purposes is reduced,
(b) emergency sampling steps which constitute a stop to supply gas to customers of all categories;
(c) limiting heating curves; the limiting heating curve refers to gas customers for heating purposes and represents a reduction in gas consumption to a level that allows heating of objects to a minimum temperature set by the recommended technical standard.
(2) The limiting sampling steps are derived from basic sampling step 3, according to which the gas supply is made in full of the agreed sample diagram.
(3) The limiting levels are:
(a) sample level 5 which reduces gas supply to customers of the category wholesale below the values given in the sample diagram;
(b) sample step 7, which reduces the supply of gas to customers of the category wholesale below the levels set by sample step 5 but above the safety and technological minimum,
(c) sample level 8, which reduces gas supply to customers of the category of medium-sized customer and wholesale customer to a minimum of safety and technology, i.e. the value necessary to ensure the safety of equipment and operators and to avoid damage;
(d) sampling stages 4 and 6 which reduce the gas supply below the values given in the sampling diagram but above the safety and technological minimum and are negotiated exceptionally for certain customers.
(4) The emergency sampling step is stage 10, the gas supply of which is interrupted to customers of all categories.
(5) The limiting heating curves are derived from the 1st heating curve, according to which the supply of gas for heating of objects is ensured without restriction, i.e. within the agreed amount of gas collected.
(6) The limiting rotation curves are:
(a) 2. a heating curve where the heating gas consumption is reduced only for certain groups of customers;
(b) (3) a heating-gas recovery curve which reduces the consumption of heating gas to all groups of customers other than household category customers to the level of safety and technological minimum temperature in heated areas.
(7) The announcement of restrictive sampling stages and heating curves in an emergency by the Central Gas Dispatch is carried out via the Czech Radio or other mass media.
(8) The announcement of an emergency emergency emergency demand stage by the Central Gas Dispatch is carried out via the Czech Radio and, where appropriate, other mass media, and is also communicated to the municipalities and authorities of the Czech Police Department mentioned in the emergency plan.
Removal of emergencies
(1) When removing the consequences of emergency situations, the holders of state authorisation shall proceed according to approved emergency plans and the specific situation in the gas system.
(2) Emergency plans are processed for:
(a) the disposal of the consequences of disturbances and accidents;
(b) the procedure for the complete interruption of gas supply according to emergency sampling step 10 for territories, cities and municipalities.
(3) Emergency plans are notified to the Central Gas Dispatch.
