14.0 Summary of the Existing Environmental Statement
for the Site and Impacts of the Proposal
14.0.1 The environmental impact statement for the existing landfill (ref 15) describes the
impacts from hazardous waste disposal operations.
14.0.2 It is submitted that the addition of a LLW stream to the inventory of waste
acceptable at the site makes no significant change to the existing environmental
impact assessment or current/future use of the site.
14.0.3 The following table is a summarised version of table 15.1 from ref 15 which
summarises the existing environmental impact assessment and to which has
been added comments on the changes introduced by the LLW stream.
