In case of mining, mineral processing and metallurgical processing, further laws have to be considered. The National Environmental Protection and Promotion Act B.E. 2535 (1992) specifies that mining, quarrying and some metallurgical processing activities must conduct an environmental impact assessment (EIA) during the license application process. Additional public hearing and expert opinion acquiring are required for some projects that might generate high environmental and social impacts. The Ministry of Industry also requires an official comment from the Local Administration Office (LAO) during the license application process in case of mining. In 2002, the Mineral Act was amended and additional conditions regarding underground mining are inserted to allow better administration of mining activities. The conditions cover not only the rules and regulations for permission and operation, but also rights of stakeholders and responsibilities relating to above-ground damages.
