Article 4 - General requirements regarding the Technical Regulations for Calculating Threshold Limit Values of Emission of Harmful Substances into the Ambient Air 1. The criteria for determining threshold limit values of emissions ('TLVE') of harmful substances into the ambient air shall be the threshold limit values of concentration ('TLVC') of harmful substances into the ambient air. 2. The TLVE shall be determined by taking into consideration the production development potential, physical and geographic and climate conditions of the location, dispersion of harmful substances in the ambient air, background concentrations created by other enterprises, the relative locations of existing and planned residential buildings, child care centres, schools, higher education institutions, sport centres, parks, public curative and preventive treatment and recreational institutions, public catering facilities, airports, airfields and railway stations. 3. The TLVE shall be determined for all stationary sources of ambient air pollution (facilities), whose activities are subject to ecological examination. The TLVE shall be determined for a term of five years for each source of ambient air pollution and for each harmful substance. 4. The TLVE for the entire enterprise shall be calculated on the basis of the TLVE determined for each source of pollution and for each harmful substance emitted by the enterprise. 5. The TLVE shall be determined for the maximum available workload of technological equipment and for gas and dust trapping devices. 6. If an enterprise has two or more sources of pollution, the dispersion of harmful substances should be calculated electronically, and the software used for such calculation must comply with the requirements of these Technical Regulations. In the case of using a different software, it must be approved by the Ministry of Environment and Natural Resources Protection of Georgia. 7. The TLVE plan shall be prepared and signed by the operator, whose activities cause the emission of harmful substances into the ambient air from the stationary sources of pollution. The TLVE plan may be prepared by the operator independently or by a natural or legal person upon the commission of the operator, as provided for by the legislation of Georgia. 8. The TLVE plan must be approved by the Ministry of Environment and Natural Resources Protection of Georgia. In the case of enterprises located on the territories of the Autonomous Republics of Abkhazia and Ajara, the TLVE plan must be approved first by appropriate agencies of the Autonomous Republics of Abkhazia and Ajara, and then by the Ministry of Environment and Natural Resources Protection of Georgia. Without the above approved document, harmful substances may not be emitted into the ambient air from stationary sources of pollution. 9. The TLVE plan may be annulled on the basis of the application of an operator, or the substantiated argument of the body authorised to approve those documents. 10. The TLVE plan may be assigned or transferred to an authorised person in the case of assignment or transfer of a stationary source of pollution, regarding which an operator must notify in writing an appropriate body authorised to approve those documents. 11. If the capacity and/or profile of a stationary source of pollution is changed, the amount of consumed fuel is increased, the current type of consumed fuel is changed and/or additionally a new type of fuel is consumed, or new sources of release and emission of harmful substances, also gas and dust trapping devices are involved in the technological processes and/or the technical specifications of the existing devices are changed during reconstruction, the approved TLVE plan shall be considered annulled and a new plan shall be prepared and approved in accordance with the new conditions. 12. After the expiration of a five-year validity period of the TLVE plan, an operator shall prepare a new plan and ensure its approval for the next five years. 13. An operator shall be responsible for the correctness of the input data provided by an enterprise for calculating the TLVE. Article 5 - Requirements for determining TLVE 1.
