FORTUM STARTS AN ENVIRONMENTAL IMPACT ASSESSMENT PROCESS OF A NEW NUCLEAR POWER UNIT AT LOVIISA, FINLAND

28 March 2007, 13:55 EEST

Fortum has decided to commence an environmental impact assessment (EIA) process
at its Loviisa nuclear power plant for a new nuclear power unit possibly to be
built adjacent to the existing two units.

As stipulated in the Finnish Nuclear Energy Act, an EIA process must be carried out before an application for a decision-in-principle can be submitted to the Council of State. “With the EIA process, Fortum raises its preparedness to build a new nuclear power unit in Loviisa. However, the company has not made any decisions on its intentions beyond the EIA,” says Fortum Senior Vice President Tapio Kuula. In the first phase of the EIA process, possible alternatives for carrying out the nuclear power project will be described. In addition, a detailed report on how the new unit's possible impacts on the surrounding communities, the environment, nature and utilisation of natural resources will be studied is composed. During the EIA process, the citizens of Loviisa and surrounding communities as well as other stakeholders will be provided an opportunity to express their opinions on the EIA and to influence how it will be carried out. Later on, stakeholders will have an opportunity to comment on the actual estimated environmental impacts. Fortum will commence the EIA process at its Loviisa power plant in April 2007 and estimates that the process will be completed during the fall 2008.
