Environmental Statement Addendum 1 (January 2010) 1.3 Following submission of the planning application the Consortium continued to consult with key stakeholders and several minor amendments were subsequently made to the proposals as well as additional information provided. These amendments were compiled into the Environmental Statement Addendum (January 2010) which was subject to formal consultation by the Local Planning Authority. Environmental Statement Addendum 2 (June 2010) 1.4 Since January 2010, additional work has progressed regarding the proposals and further consultation undertaken with key stakeholders. The VoG Council commissioned Capita Symonds to review the submitted Transport Assessment and comments were provided on 8 February 2010. An updated Transport Assessment has now been prepared in response to the comments received. The production of the updated Transport Assessment has implications which need to be considered through the EIA in particular the related assessments for air quality and noise. 1078208v5 P1 1.5 In addition, there have also been further minor design changes following dialogue with the VoG Council and the Design Commission for Wales which need to be considered. 1.6 As a result, a second
