Cabinet of Ministers Regulations No. 626 in 2004 (27 July. No 45, § 36) provisions on polluting activities-smell detection techniques, as well as the order in which restricts the smell spread Issued in accordance with the law "on pollution" in article 11, second paragraph, point 8 i. General questions 1. determines: 1.1. induced pollutant smell detection methods; 1.2. the procedures for limiting polluting activity caused by the odor from spreading.
2. the terms used in the rules: 2.1 the odor unit (ou)-smelling substances the quantity injected per cubic meter, neutral gases under standard conditions causes a physiological reaction olfactory organs, at least half of the members of the Group of assessors smell; 2.2. the gas under standard conditions – gas if the pressure at a temperature of 293 oK is 101.3 kPa; 2.3. smells assessors – people group, established in accordance with the provisions referred to in paragraph 3 of the base or reference; 2.4. the concentration of the odor-odour units (ou) per cubic metre of gas under standard conditions; 2.5. target smell – air quality regulations for odors that cause or may cause permanent or periodic smell disorders and expressed with the odor concentration (ou/m3) under standard conditions as the average concentration of the scent, which is specified using a temporary concentration measurements an hour; 2.6. smell perception threshold-the concentration of smelling, if at least half the stink of the members of the Group of assessors (in accordance with the provisions referred to in paragraph 3 of the base or reference conditions) confirms the presence of scent and if it's a 1 out/m3; 2.7. the disturbance of smell, smell a negative effects on the well-being of people; 2.8. the smell nuisance threshold-the concentration of smelling, if at least half the stink of the members of the Group of assessors (in accordance with the provisions referred to in paragraph 3 of the base or reference conditions) confirms the negative effects of odors on human well-being. Smell disorder is greater than the threshold odour perception threshold and may exceed the target values or be less than this depending on the frequency, intensity of the smell, the duration, the hedonic tone (revolted) and space character.
II. determination of the Odour 3. Odor concentration in the measurement for the base method (reference) use the standard LVS EN 13725:2003 "air quality. Determination of the concentration of odours by dynamic olfaktometrij method referred to "or other equivalent or a better method.
4. Odor concentration measurements according to the standard LVS EN ISO/IEC 17025:2001 L accredited laboratories for which accreditation has published a statement in the newspaper "journal". 5. the assessment of the concentration of the odor is allowed to use the computer program of dispersal of pollutants mentioned in the Cabinet's April 22, 2003 regulations no 200 "for emissions from stationary sources of pollution limit project development". The modeling process of the odor concentration compared with that rule 6, 7 and 8 of this smell target value. 6. Smell target-5 ou/m3, not to be exceeded more than seven 24-hour annual. The smell is allowed to exceed the target at a time when the implementation of the provisions of paragraphs 17 and 19 of these measures or the programme of action for the prevention of odours (hereinafter referred to as the programme), developed in accordance with the provisions of paragraph 20.
7. Agricultural land will reek target-8 ou/m3, not to be exceeded more than seven 24-hour annual. The smell of the target value of utilised agricultural area will exceed the allowed period, determined in accordance with the provisions of paragraph 22 and 23. 8. Stranglehold-10 target ou/m3 – set in (A), (B) and (C) polluting activities of category, not to be exceeded more than seven 24-hour annual. Polluting activities target the specific smell allowed to exceed, if those provisions are complied with the conditions referred to in paragraph 14.1., as well as the time when measures are being implemented to prevent smell in accordance with the provisions of 14.2.
III. Procedures for limiting polluting activity caused by the odor spread 9. regional environmental administration (hereinafter referred to as the Government) appreciates the smell nuisance. If smell disorder assessment results show that the smell has been exceeded, the administration target prepares the decision on measures for the reduction of interference the smell. 10. the decision on the measures of interference reduction and odor smell disorder evaluation results the Board shall submit to the operator, the legal or natural person who has created the pollutant activities in the smell disorders, local government, as well as the Administration put website on the internet. 11. by paragraph 10 of these rules of receipt of the decision referred to the operator, the legal or natural person or local Government takes steps to reduce disturbance of smell month submit to the Government a plan of measures for the harmonisation of odor elimination of distortions and the timetable for implementation. The agreed action plan and timetable authority placed the site on the internet. 12. If A or B category contaminating activities due to the emission of pollutants causing or likely to cause odour problems, develop emission limit operator. The project includes an application for a permit for a category A or category B polluting activities. 13. If A or B category contaminating activities, emissions of pollutants exceeding target, smell draw up action plans for the prevention and the smell of the timetable for implementation. The plan shall be coordinated with the administration. The Board reviewed the conditions of the permit and, if necessary, to supplement them. Harmonisation of the conditions of the authorization operator is obliged to take certain measures in accordance with the approved schedule. 14. If category A and B activities, best available techniques (category A polluting activity) or cleaner technology (polluting activities of category B) does not provide a reduction to a specific smell smell smell that does not exceed the concentration target: 14.1. issuing to the operator under the category permission for the activity of the pollutant, if the local authority has agreed to sign over the target; 14.2. and in accordance with these rules is not coherent paragraph 14.1. stench of excess, the target operator and local development and local government approved the programme of action, including the provision of the information referred to in the annex.

15. If the polluting activities of category C due to the emission of pollutants into the air causing the odor concentration exceeding the target value, Manager of the smell (C) polluting activities of category certificate defines the operator binding requirements smell disorders. 16. the polluting activities in accordance with the law "on pollution" are not classified as category A, B and C of the polluting activities and resulting in an emission of pollutants in the air can cause odor concentration is higher than the target value, smells, the operator shall ensure compliance with the target values of the smell. 17. to prevent the rules referred to in point 16 smell target, Government technical regulations (transaction that does not require an environmental impact assessment) or in a separate decision by operator binding requirements for the Elimination of distortions of smell. 18. Economic activities related to petroleum products, chemicals and chemical products as well as shipments of waste and which are in accordance with the law "on pollution" are not classified as category A, B and C, as well as polluting operations are due to the emission of pollutants in the air can cause odor concentration exceeding the target smell (near roads, railways, road transport parks (also the bus station), railway stations), operator carrying out polluting activities, ensure compliance with the target values of the smell. 19. in order to prevent the provisions of paragraph 18 of that smell target, Government technical regulations (transaction that does not require an environmental impact assessment) for transaction or in a separate decision by operator binding requirements for the Elimination of distortions of smell. 20.
