the supervision of the Environmental Agency regarding the impact of waste
disposal due to mining without a permit on the Ongkag River, Dumoga District,
Bolaang Mongondow Regency. And whether there are any obstacles faced by the
Environmental Agwency in monitoring the impact of waste disposal due to mining
without a permit on the Ongkag River, Dumoga District, Bolaang Mongondow
Regency. The legal research used is empirical or field research which focuses on
field data as the primary data source, namely the results of interviews. This study
concludes that the Bolaang Mongondow Regency Environmental Agency, in
carrying out supervision was under its duties and authority. However, the charge
carried out by the Department of the Environment has yet to be maximized. This is
because the Environmental Agency cannot stop mining without a permit
unilaterally, considering the economic and social aspects of Bolaang Mongondow
Regency. In carrying out supervision, the Environmental Agency experienced
several obstacles. The pollution in the Ongkag River came from mining without a
permit, so it could not be measured and monitored. In addition, the
Environmental Agency had limited human resources and tools to carry out
supervision. The Environment Agency conducted data collection, assistance, as
well as guidance on mining without a permit. The Environment Agency also need
to increase the number of human resources and pay attention to the monitoring
tools used hence that monitoring efforts can be carried out optimally.
