§ 21790. CIWMB -Preliminary Closure Plan Contents.
(a) The purpose of the preliminary plan is to provide a basis for the operator to establish a preliminary estimate of closure costs certified for accuracy by a registered civil engineer or certified engineering geologist, and enable the CIWMB to assess the reasonableness of the cost estimate for non-water quality aspects of closure.
(b) The plan shall identify the steps necessary to perform either partial final closure, in accordance with §21120, or complete landfill closure and shall include, but is not limited to, the following information:
(1) a closure cost estimate pursuant to §§21815 and 21820;
(2) location maps indicating property boundaries and the existing, permitted, and proposed final limits of waste placement; entry roads; and structures outside the property boundary but within 1000 feet of the property boundary.

(4) a location map of the current monitoring and control systems including: leachate control and drainage and erosion control systems as required pursuant to chapter 3 (§20180 et seq.); landfill gas monitoring and control systems as required pursuant to chapter 3 (§20180 et seq.);
(5) a description of proposed postclosure land uses;
(6) an estimate of the maximum extent of the landfill that will ever require closure at any given time during the life of the landfill;
(7) an estimate of the closure date based on volumetric calculations, including supporting documentation. The estimate shall account for the effects of settlement and for volume occupied by daily cover material; and
