Cabinet of Ministers Regulations No. 580 in 2015 (13 October. No 54 4) requirements for biogas and biomass-produced gas and gaseous state into liquefied natural gas for transport to enter and natural gas transmission system, Issued in accordance with article 26.2 of the energy law fifth 1. determines the technical and security requirements for biogas and biomass-produced gas and gaseous state into liquefied natural gas for transport to enter and natural gas transmission system as well as gas quality characteristics to enter the transport of gas and natural gas transmission system would be safe. 2. the terms used in the rules: pamatgāz 2.1-natural gas transported in the natural wells for natural gas; 2.2. aizvietotājgāz – the biogas or biomass-produced gas (hereinafter biometān) and gaseous state converted to liquefied natural gas, which is the same gas pressure, temperature and gas installations in the same framework show the identical pamatgāz combustion characteristics. Aizvietotājgāz is used in place of pamatgāz; 2.3. additive gas – biometān, which is different from the quality characteristics of pamatgāz and that adding pamatgāz to obtain the necessary quality characteristics or mixing with conditioning gas acquires aizvietotājgāz; 2.4. conditioning of gas-gas or gas mixture with the corresponding combustion technical parameters and values that are mixing with additive gas acquires aizvietotājgāz; 2.5. system service agreement-agreement concluded between the system operator with the system of the natural gas transmission system services and other services; 2.6. connection point-the place where aizvietotājgāz is entered in the natural gas transmission system; 2.7. the mixing point, the place where the gas additive are homogeneous mixing with conditioning or pamatgāz, gets a aizvietotājgāz. 3. enter a Aizvietotājgāz natural gas transmission system in accordance with the service agreement which switch system user and system operator. 4. The system provides for biogas and biomass-produced gas and gaseous state converted to liquefied natural gas entry and transport natural gas transmission system according to the law and the Latvian National Standard (EN) requirements, as well as Latvian National Standard status and other adapted International Organization for Standardization standards and standards in www.lvs.lv tīmekļvietn is published by the national standardization bodies. 5. Natural gas transmission system, minimum pressure of 25 bar. To ensure the input of aizvietotājgāz natural gas transmission system, its pressure must exceed the actual pressure of pamatgāz not more than 5 bar. 6. the user shall ensure that the construction of the gāzapgād system, which turns off the option to enter a natural gas transmission system in gas, which do not conform to the quality characteristics of these rules, the requirements set out in the annex. 7. the user is obliged to ensure that the natural gas transmission system in the treatment of aizvietotājgāz of ammonia and amines, as well as the homogeneous mixing of the mixture formation. 8. The users of the system will ensure the mixing obtained and entered in the natural gas transmission system in compliance with the provisions of the aizvietotājgāz specified in the annex can be entered to the natural gas transmission system and transported aizvietotājgāz quality characteristics. 9. System user access point continually make natural gas transmission system that can be entered into the aizvietotājgāz of inventory and quality characteristics by using the appropriate certification and verification of measuring equipment, as well as provide this data accumulation and the continuous remote access to aggregated data. 10. the system operator shall have the right to legal and system service in the cases laid down in the Treaty, to stop the entry of aizvietotājgāz natural gas transmission system. The Prime Minister is the Rapidity of economic Newsletters, Minister Dana Reizniec-Oak annex Cabinet 13 October 2015 regulations No 580 in the natural gas transmission system can be entered and transported the quality characteristics of aizvietotājgāz No. PO box Parameters measurement value 1.
