INTRODUCTION 1.1 Background and Purpose of this Addendum to the Final Environmental Impact Report In April 2004, a Final Environmental Impact Report (EIR) for the Los Angeles International Airport (LAX) Proposed Master Plan Improvements was published by the City of Los Angeles, the lead agency for the project under the California Environmental Quality Act (CEQA). The Final EIR represented the culmination of a comprehensive multi-year evaluation of the potential impacts associated with several alternatives for the LAX Master Plan, including the preparation and public review in 2001 of a Draft EIS/EIR for the proposed project, as well as the preparation and review in 2003 of the Supplement to the Draft EIS/EIR. The Final EIR reflected the information and analyses presented in those documents. Also included as part of the Final EIR were the public and agency comments received during the public review periods for the Draft EIS/EIR and the Supplement to the Draft EIS/EIR, as well as written responses to each of those comments. Subsequent to the publication of the Final EIR, Los Angeles World Airports (LAWA) decided to prepare this Addendum to the Final EIR to provide additional information that clarifies and amplifies the contents of the Final EIR. In accordance with Section 15164(c) of the State CEQA Guidelines, an addendum need not be circulated for public review and an additional round of public comments, but can be included in or attached to
