5.3. The competent authority appraising environmental impact assessments and issuing environmental permits shall specifically determine the pollution parameters to be controlled at the proposal of the investment project owner or facility in the dossier of application for environmental impact assessment appraisal or the dossier of application for issuance, adjustment, re-issuance of an environmental permit. In cases where other pollution parameters are detected exceeding the maximum permissible values prescribed in Table 2 of this Regulation, supplementary control shall be required in accordance with regulations.
6. ORGANIZATION OF IMPLEMENTATION
6.1. The provincial-level People's Committees shall be responsible for reviewing and adjusting local environmental technical regulations on industrial effluent to be consistent with legal regulations, the local socio-economic development situation, and this Regulation.
