According to Article 54 (3) of Act No. 224 / 2015 Coll., on the prevention of major accidents caused by selected hazardous chemicals or chemical mixtures and amending Act No. 634 / 2004 Coll., on Administrative Charges, as amended, (Act on the Prevention of Major Accidents) ("the Act '):
§ 1
Preliminary provisions
This decree implements the relevant European UnionRegulation (1) and provides for
(a) the principles for defining the emergency planning zone and the procedure for defining it; and
(b) the content and structure of the external emergency plan.
§ 2
Basic concepts
For the purposes of this decree:
(a) by parameter L, the minimum distance between the initial limit of the emergency planning zone and the installation;
(b) by a type scenario, a simplified course of a major accident which may result in fatal or irreversible effects on the health of unprotected persons;
(c) a modification factor of a numerical value that characterises the expected consequences by type scenario and hazard of a substance or group of substances of the same classification and similar physicochemical properties that affect the determination of the size of the emergency planning zone;
(d) an effective quantity of the value obtained by multiplying the quantity of the substance in the device by the modification factor to be used for reading on the chart of the relevant type scenario.
§ 3
Principles for defining an emergency planning zone
(1) The emergency planning zone is defined as the area bounded by the external boundary of the emergency planning zone (hereinafter "external borders"), with the exception of the territory for which the internal emergency plan is being processed.
(2) The initial limits of the emergency planning zone (hereinafter referred to as "default limits") are defined as the minimum area in which, in the case of the implementation of a type-scenario, the population protection measures apply.
(3) The external border is defined from the starting line as the resulting boundary of the emergency planning zone set out in Section 5.
(4) The starting limit is the threshold for the determination of the external boundary of the emergency planning zone as set out in Annex 1 to this Decree.
§ 4
Determination of baseline
(1) The default limit is determined
(a) as a circle concentrated with the smallest circle inscribed around the floor projection of an object or device, the basis for determining its radius being the L parameter determined in accordance with Annex 1 to this Decree; the model is shown in Figure 1 and 2 of Annex 1 to this Decree,
(b) as a boundary for the area defined by the distance of the L parameter on either side of the pipe axis in the case of a pipe installation, the L parameter determined in accordance with Annex 1 to this Decree being the basis for the distance determination; the model is shown in Figure 3 of Annex 1 to this Decree,
(c) using the highest value of the L parameter, when the equipment includes different hazardous substances or allows different type scenarios to be evaluated; the model is shown in Figure 4 of Annex 1 to this Decree,
(d) by increasing the parameter L with the radius of the smallest circle inscribed around the ground plan projection of the device if this radius is greater than or equal to 1 / 5 of the L parameter; the pattern is shown in Figure 5 of Annex 1 to this Regulation,
(e) for the surface technologies of underground gas storage tanks and operating probes of underground gas storage tanks in the natural layers, waterborne layers and caverns referred to in Annex 1 to this Regulation and the parameters L in the territory of one protected area for special interference with the earth's crust are considered as one emergency planning zone for one operator; the model is shown in Figure 6 of Annex 1 to this Decree,
(f) as the limit of the unification of several surface areas determined in accordance with points (a) to (e), where several installations of one or more operators are located in a common demarcated area; the specimen is shown in Figure 7 of Annex 1 to this Decree; or
(g) using risk analysis and evaluation outputs (11), in compliance with the rules set out in Annex 1, Section 3, unless the starting limit can be determined in accordance with points (a) to (f).
(2) If the default limit is equal to or less than the area of the area of the object for which the operator processes the internal emergency plan, the emergency planning zone shall not be determined.
§ 5
Procedure for establishing an external border
(1) The external borders shall be determined from the starting limit by adjustment according to urban, field, demographic or climate conditions, or other factors of good concern, taking into account the possibility of domino effect. The adaptation shall take into account, in turn, these principles:
(a) the external borders must be established in such a way that:
1. take into account conditions which may affect the dispersion of dangerous substances, the spread of heat or pressure waves; and
2. do not divide individual houses or housing units, or divide populated areas due to the nature and intensity of the threat and the planned measures to protect the population; and
(b) the external borders shall monitor parts of the boundaries of the administrative territories or, where applicable, the boundaries of the land, where the boundaries of the administrative territory or the border of the land cannot be used, the external borders shall respect natural borders such as water flows, roads, highways or railway lines.
(2) The emergency planning zone is marked in the map base on a scale appropriate to the purpose of using the map base or electronically in the geographical information system and makes it available to the public via the regional geoportal.
§ 6
Content and structure of the external emergency plan
(1) The elements of the content of the external emergency plan and its structure are set out in Annex 2 to this decree.
(2) The basis for drawing up an external emergency plan is:
(a) a demarcated emergency planning zone;
(b) the supporting documents drawn up by the operator of the building included in Group B, in particular the safety report and other supporting documents from the operator;
(c) the supporting documents provided by the public authorities concerned; and
(d) a statement by the public and the municipalities concerned on its proposal.
(3) The Fire Department of the Region may, if necessary for the preparation of an external emergency plan, request additional documentation.
§ 7
Transitional provisions
(1) The emergency planning zones defined in accordance with Decree No. 103 / 2006 Coll., laying down the principles for the definition of the emergency planning zone and on the scope and manner of drawing up the external emergency plan, shall be considered, for a period of 18 months from the date of entry into force of this Decree, as the emergency planning zones defined in accordance with this Decree.
(2) External emergency plans prepared under Decree No. 103 / 2006 Coll. are considered to be external emergency plans under this Order for a period of 30 months from the date of entry into force of this Decree.

Annex No 1 to Decree No. 226 / 2015 Coll.
Definition of emergency planning zones

a) Creating a device inventory
1. Information shall be collected on all equipment and methods of transport of hazardous substances in the premises. For each installation, further information shall be found to determine the maximum quantity of dangerous substances which may cause a major accident by their dangerous effects and the relevant category of dangerous substances as defined in Tables I and II of Annex 1 to the Act. This is based on the operator's documentation, in particular the documentation for the establishment of the emergency planning and processing area of the external emergency plan, the safety report (in particular the risk assessment of a major accident), the internal emergency plan and other necessary data requested by the county authority, as well as the data requested by the fire brigade of the county according to Act No. 239 / 2000 Coll., on the Integrated Rescue System and on the amendment of certain laws, as amended. The device shall be entered in Table A.2, column 2, followed by the appropriate name of the dangerous substance and the hazard category in column 1. In Table A.2. also the equipment in the buildings designated under Section 7 (1) of the Act is included.
2. A pipeline shall also be considered as an installation where it connects two installations where the sum of their preliminary parameters 1 calculated in accordance with point (e) of this section is less than their distance. For multiple interconnections of two devices, the first sentence shall be considered separately for each line. In the case of a line between two devices, the route can be divided into separate sections, meaning the fittings of the separately closed part of the pipe. These are automatic or remote-controllable fittings with an independent source of energy, or shut-off fittings which, in case of loss of control, close themselves with force of gravity, spring or pressure.
(b) Assignment of accident type scenarios
1. One or more type scenarios according to Table A.3 shall be assigned to each individual installation in column 4 based on the type of dangerous substance. Devices with a hazardous substance not listed in Table A.3 shall be assigned to the hazard category of the hazardous substance in accordance with Table A.4. Where multiple type scenarios are assigned to a hazardous substance, those scenarios for the installation concerned shall be indicated in column 4 as separate items, in separate rows. The following principles, respecting the type of equipment, shall be followed when assigning a type scenario:
1.1 The amount of hazardous substance in linked sources of risk is not added when the FireBall from BLEVE type scenario is assigned; individual devices are assessed separately. It shall be evaluated by the quantity in one container.
1.2 The type scenario FireBall from BLEVE is not assigned for atmospheric storage, for storage in cylinders, for manifold distribution of flammable gases and for underground storage tanks and semi-sealed storage tanks.
2. In the case of underground gas storage probes, the type scenario shall not be assigned.
(c) Determination of hazardous substances
1. For each installation, column 3 and 5 of Table A. 2. the quantity of dangerous substance placed and the state in which the substance is present. Where devices are interconnected and do not have sufficient effective separation between them, the sum of the quantities of the hazardous substance in those devices shall be used to determine the quantity of the hazardous substance used to determine the type scenario.
2. The existence of separate sinks for individual tanks with sufficient distance between the edge of the pit and other tanks, the use of automatic or remote-controlled shut-off fittings with an independent source of energy, the shut-off fittings which, in the event of loss of control, close themselves, or a sufficiently durable mechanical barrier between devices shall be considered to be effective separation.
3. In the case of a gas pipe installation for which it is not possible to determine the maximum quantity of dangerous substance from the operator's documentation, the maximum quantity of dangerous substance shall be determined in accordance with Chart 6. The maximum amount of the hazardous substance determined in accordance with Chart 6 may not exceed the sum of the maximum quantities of the hazardous substance in the gas-connected pipeline installations.
4. For surface technologies of the underground gas storage tank, including extraction probes, the pressure is given instead of the quantity of the hazardous substance, the preliminary parameter 1 is deducted from Table A.3.
(d) Calculation of the effective amount of hazardous substance
The effective amount of the dangerous substance shall be calculated by multiplying the maximum quantity of the dangerous substance (column 5 of Table A.2) by the relevant modification factor of the dangerous substance listed in Table A.3. or by the relevant modification factor of the dangerous substance listed in Table A.4.
For toxic liquids, the maximum amount of dangerous substance shall be determined by:
1. for the chemicals listed in Table A. 3. by multiplying the quantity of hazardous substance by the coefficient of fumes KV, which is subtracted from Table A. 1. using equation 1,
2. for chemicals and mixtures not listed in Table A. 3. by multiplying the quantity of dangerous substance by the coefficient of fumes KV, to be deducted from Table A. 1. using equation 1.
The resulting value is entered in column 7 of Table A.2.
For surface technologies of underground gas storage tanks, including extraction probes, no effective amount is determined.
(e) Determination of preliminary parameter 1
The preliminary parameter 1 shall be determined on the basis of its constant value as shown in Table A.3. or Table A. 4. or on the basis of Chart 1, 2, 3, 4 or 5 according to the relevant type scenario. The resulting value shall be given in column 8 of Table A.2. The preliminary parameter 1 is determined separately for each item as the separate row of Table A.2. If the distance from graphs cannot be subtracted for a small value of effective quantity, the preliminary parameter 1 of 50 m shall be determined.
(f) Determination of parameter L
The L parameter shall be determined as the maximum achieved value of all preliminary parameters 1 obtained in accordance with the procedure referred to in point (e) of this section. The L parameter shall be entered in column 9 of Table A.2.

Rules for setting the L parameter using the results of the analysis and risk assessment
1. Selection of the type scenario: it is related to the individual physicochemical properties of chemicals and mixtures and the method of handling and respects the type scenarios according to Table A. 3 and A. 4.
2. Quantities of dangerous substances and mixtures: account is taken of the quantity which is actually expected to be involved in the accident. This does not need to be the quantity proposed in the installation, but the reduction must be defined and justified, for example by the nature of the technological process.
3. The speed of release of hazardous substances into the air: the release rate respects the physical state and conditions of the substance (e.g. storage form as liquefied or compressed gas, steam tension above the surface, concentration of hazardous substance in the mixture during leakage, powder or compact form of the substance).
4. Reducing factors: can only be counted for effective separation to prevent leakage, possibly reducing leakage from equipment (passive safety barriers). Organisational measures, i.e. mitigation requiring active intervention by operators or rescue personnel, cannot be counted.
5. Limit effects on human health (substance concentration, heat flow, overpressure): recommended are the lowest estimated values that can cause death to a person who is not an extremely susceptible individual.
6. Fire-related technical and explosive characteristics of substances / mixtures: use of only supported values of fire-related technical and explosive characteristics of substances / mixtures.
7. Atmospheric conditions: it is recommended to use air stability class D according to Pasquill and wind speed 3 m / s or less, or worse, values of dispersion conditions. If other variance conditions are used, this choice shall be justified.
8. Temperature of dangerous substance: the temperature of the substance is taken into account in equipment, including in exceptional technological conditions.
9. Gas density for the dispersion model: the choice is made according to the molecular mass of the hazardous substance, the concentration and temperature of its mixture with air (e.g. the diffusion model "Heavy gas dispersion").
10. Time and speed of leakage of dangerous substance from the device: both values must be justified. If this is not the case, the time of leakage of all expected quantities in 30 minutes shall be taken into account. If justified leakage time values are used, these values shall be equal to at least the time needed to identify the accident plus 10 minutes.
11. Calculation of liquid leakage: the nature of the device shall be taken into account. From an escaped substance formed by a puddle of justified dimensions, or a puddle of an area corresponding to the dimensions of the canister.
12. Quantities of hazardous substances involved in reaction: for explosives, the maximum quantity present in a particular warehouse or facility. In the case of flammable gases and vapours, it shall be stated which part of the leaked quantity is involved in the reaction, the models used and the input conditions used.

Annex No 2 to Decree No. 226 / 2015 Coll.
Content and structure of the external emergency plan
The external emergency plan contains a text and graphic section. The text section contains information and operational information and plans for specific activities. The graphical part serves for the graphic display of the basic information of the text section and contains maps, graphs, diagrams, deployment of forces and means, deployment methods and so on.
The territory of the emergency planning zone may be divided into two or more sectors and their sections for the purpose of addressing the major accident of the installation. Depending on the direction or route of the release of the hazardous substance and the monitoring results, the protective measures provided for in the external emergency plan shall be applied in these sectors (their sections). The relevant measures shall be processed according to the specific characteristics of the dangerous substance and the scenarios for its operation outside the installation in an accident for each sector. In the immediate vicinity of the installation or near the penetration of the substance into the environment (water, soil or air), appropriate and pre-determined measures shall, as a general rule, be applied regardless of the extent of the spread of hazardous substances in the event of an accident and of the results of the monitoring of the situation ("emergency measures'). The process of sectoral borders will be adapted to local urban, terrain, demographic and climate conditions, or other factors of interest.
Safeguard measures shall be planned in the form of specific action plans for the relevant parts of the emergency planning zones, their selection and the way in which they are processed shall be chosen in proportion to the size of the zone and the nature of the threat.
Where the requirements for the contents of the individual parts of the external emergency plan are contained in at least the same range for the emergency planning zone in another planning documentation addressing the problem of population protection, a reference may be made to this dossier and only specify the specificities of the emergency planning zone in the external emergency plan.
The external emergency plan shall be divided into:
A. Information
The information part contains:
(a) identification of the operator, description of the objects and equipment, identification of the source of the risk;
(b) the characteristics of the territory of the emergency planning zone, in particular geographical, demographic, climatic, hydrogeological, and description of the infrastructure;
(c) an overview of buildings in which more people can be expected to be present (e.g. school, health and social facilities, sports facilities, shopping centres),
(d) definition of the emergency planning zone;
(e) an overview of the number of persons in the emergency planning zone (including persons present in the emergency planning zone temporarily, for example in employment, school, health and social facilities),
(f) emergency preparedness organisation in the emergency planning zone;
(g) the list and characteristics of the major accident effects considered, including a description of their expected impacts (including the domino effect); and
(h) basic information on the effects of a dangerous substance on the human organism and the basis of the provision of first aid for the use of a dangerous substance by individuals.
B. Operational part
The operational part shall provide an overview of the measures prepared, which shall be carried out after notification, warning and informing the operator of the suspicion or occurrence of an accident. It shall develop solutions to individual measures depending on the expected situation and its expected time sequence, including agreements on the security tasks of individual administrations or legal and business individuals in implementing urgent measures. The implementation of individual measures shall be ensured according to the plans for specific activities, depending on the nature of the accident.
The operational part contains:
