1-4 Stage V Stage V is an 11.8-acre area as shown on Figure 5. This area includes final fill slopes along the northeast of the northern portion of the landfill up to an elevation of 90 feet AMSL. The closure volume estimates are based on the top of waste fill plan down to the master plan base grades. As part of this project, the area will be cleared and grubbed, as necessary, and the closure improvements constructed (e.g., final cover, permanent drainage, landfill gas system modification, etc.). Stage VI Stage VI is a 20.7-acre area as shown on Figure 6. This area includes the northern final fill slopes adjacent to Stages I, IV, and V up to an elevation of 150 feet AMSL. The closure volume estimates are based on the top of waste fill plan down to the master plan base grades. As part of this project, the area will be cleared and grubbed, as necessary, and the closure improvements constructed (e.g., final cover, permanent drainage, landfill gas system modification, etc.). Stage VII Stage VII is a 166.7-acre area as shown on Figure 7. This area includes the entire deck area of the landfill up to an elevation of 200 feet AMSL. The closure volume estimates are based on a "flat deck" at an elevation of 200 feet AMSL down to the master plan base grades. As part of this project, the area will be cleared and grubbed, as necessary, and the closure improvements constructed (e.g., final cover, permanent drainage, landfill gas system modification, etc.). Stage VIII Stage VIII is a 24.1-acre area as shown on Figure 8. This area includes the entire deck and slope area of the southern most portion of the landfill. The closure volume estimates are based on a "flat deck" down to the master plan base grades. As part of this project, the area will be cleared and grubbed, as necessary, and the closure improvements constructed (e.g., final cover, permanent drainage, landfill gas system modification, etc.). 1.3 Maximum Extent of Landfill That Will Ever Require Closure In accordance with 27 CCR, Section 21790(b)(6),the maximum extent of the landfill that will require closure at any given time during the life of the landfill is approximately 187 acres. Table 1 presents the anticipated staged closure acreages versus the liner development phases to show the maximum extent that would ever require closure. As shown, liner development Phases 1, 2, 3 and 4 would be completed before the Stage I closure is implemented creating the basis for maximum extent. The site's closure staging was developed so as to not interfere with active disposal operations.
