0 1.0 PRELIMINARY CLOSURE PLAN AMENDMENT 1.1 Introduction The following Preliminary Closure/Post-Closure Maintenance Plan Amendment (PCPCMP) for Forward Landfill (FL) updates the existing Preliminary Plan prepared by Bryan A. Stirrat & Associates, Inc. (BAS), Lewis Engineering, and Geologic Associates (GLA) (2002) and the subsequent revision submitted in 2004 (Amendment No. 2). Specifically, Amendment No. 2 (dated March 2004) included language regarding the phased closure (partial closure) of the site including the associated reduction to the maximum extent of the landfill ever requiring closure, as well as, the accompanying closure cost estimate. Pursuant to CCR Title 27 (27 CCR), Section 21790(a), the purpose of a Preliminary Closure Plan is to provide a basis to establish a preliminary estimate of closure costs and post -closure maintenance costs for the landfill. The 2002 PCPCMP met this requirement; however, the objective of Amendment No. 2 is to identify the information to gain agency approval. The information listed below is included in this PCPCMP Amendment: Engineering Design Plans (Closure Sequencing Plans) presenting the anticipated staged closure of the FL, which also shows existing and proposed final limits of waste placement (liner area); • Stage 1A closure was completed in 2006 in response to actions requested by the Regional Water Quality Control Board, Central Valley Region. A Partial Final Closure/Post-Closure Maintenance Plan (included as Attachment 2) reflecting the closure of the Stage 1A area was submitted and approved by the regulatory agencies in 2005. The Stage 1A area consisted of 30.2 acres. A revised estimate of the maximum extent of the landfill that will ever require closure at any given time during the life of the landfill based on the Staged Closure Sequencing Plans to 187.6 acres reflecting the Stage 1A closure (refer to Section 1.3); Anticipated closure schedule for the initial closure stage based on volumetric calculations; and A revised closure cost estimate based on the maximum extent of the landfill ever requiring closure as based on the Closure Sequencing configuration. This 2008 revision (Amendment No. 3) provides updated information related to the phased closure of the FL (Amendment No. 2), specifically related to the implementation of the Stage IA closure and post -closure cost estimates prepared in compliance with 27 CCR and the subsequent reduction of the maximum extent of area ever needing closure over the active life of the landfill. 1 SWT Engineering Forward Landfill - PCPCMP Amendment (Z:\PROJECTS\Allied Waste\Forward\JN81013 5 yr Review Plan\JTD Amd 3 PCPCMP Amd 3 Dec 08\PCPCMP Amend 3 121808.doc; Amendment No. 3: 12/18/08)
