A mining company that employs an independent contractor to conduct mining operations retains ultimate responsibility for ensuring compliance with environmental legislation and approved Environmental Management Programmes, and failure to adequately oversee such compliance constitutes criminal negligence sufficient to establish liability under NEMA and the National Water Act. Activities that mine within wetlands, divert watercourses, fail to implement adequate pollution controls, and commence listed activities without environmental authorization constitute contraventions of Section 28(14)(a) of NEMA, Section 151(1)(a) read with Section 21(c) and (i) of the National Water Act, and Section 24F(1)(a) of NEMA respectively. In sentencing for environmental offences, courts must balance the serious nature of environmental crimes and constitutional environmental rights against mitigating factors, and may impose creative sentences including suspended fines, mandatory rehabilitation, ongoing monitoring, and payments to environmental research and protection institutions to achieve both punitive and restorative objectives. The duty of care expected of those engaged in regulated activities, particularly mining, requires them to take active steps to learn and ensure compliance with applicable environmental law.
