The main control instrument of environmental protection is the Environmental Protection Act, which aims at preventing the pollution of the environment. The Act is applied to activities that lead or may lead to environmental pollution and to activities generating waste and treating waste. The Environmental Protection Act is applied in parallel with the Waste Act. With regard to economic activities the most important feature of the Environmental Protection Act is that it requires that an environmental permit must be applied for activities that may lead to environmental pollution. The Appendix of the Environmental Protection Act lists the forms of activities which require an environmental permit or a written notice as well as the activities that require registration. The activity may also be subject to a permit procedure under the discretionary requirements stipulated in the Environmental Protection Act.
