Abstract
The environmental impact assessment has gained a very important role in decision making processes regarding different projects,
investments, actions and proposals. The environmental impact assessment is a systematic process which deals with the
consequences of the future developments in advance. The methodology of the assessment includes several techniques. The
quantitative methods focus on the evaluation of the impacts by assigning importance values to the environmental parameters and
quality scores. A quantitative method devised previously was further developed and a protocol for the determination of the
complex environment state index was devised. This method is adapted for a disposal facility and conclusions are made on the
environmental impacts of the company.
The environmental impact assessment method devised was used for a disposal facility exhibiting high environmental risks. The
objective of the paper is to test this method on a red mud disposal facility in Hungary in light of the legal stipulations and limit
values to support the more efficient operation of the environmental management system of the company with identification of the
significant environmental issues.
