Environmental approval and EIA are two means of control that regulate Danish industrial companies. Today, these means of control operate in two separate processes, which causes a variety of weaknesses. The weaknesses are a long review process, a complex legislation and overlaps between the two means of control. The aim with this report is to simplify the environmental regulation of industrial companies, through a proposal for how environmental approval and EIA can be integrated into one law. The law is named the industrial law. In the report environmental approval and EIA are integrated by integrating 11 components of the two means of control. The components are: Aim, Application, Distribution of responsibility, Types of companies, Aspects, Factors, Documentation, Legal effect, Demands and control, Public hearing and Appeal. In the preparation of the industrial law the Law about environmental approval etc. of animal husbandry is used, because this law provides insight in to how environmental approval and EIA can be integrated. Six of the components are integrated like it is done for animal husbandry in Law about environmental approval etc. of animal husbandry. The five remaining components are not integrated like it is done for animal husbandry, because these components are different for husbandries and industrial companies. Therefore, these are integrated specifically for industrial companies. The integration of the components results in a proposal for the industrial law. In the law the comprised industrial companies are divided into three categories. In the law some rules apply for all the comprised industrial companies, while other rules depend on the category of the industrial company. In closing, the proposal for the industrial law is quality-assured and improved through an evaluation.
