Nickel and Vanadium Emissions (Hansard, 13 December 1994)

§ Mr. Atkins

[holding answer Thursday 8 December 1994]: All large combustion plants burning oil, coal or orimulsion will release vanadium or nickel. The table provides as much information as the inspectorate has been able to assemble without disproportionate expense. This information covers 1993.

¹ No limit specified in the authorisation document.
² Annual actual releases have been calculated from information in the application together with 1993-94 operating data. These figures are believed to be reasonably representative of releases for 1993. There is little information available for the last three years.
³ This power station has limits of 0.435 for vanadium and 0.175 for nickel with respect to releases to water.
