[Note: see also the SWRCB's clean closure requirements under § 21090(f) ]

(a) The operator of a solid waste landfill may submit a closure plan for solid waste landfills that will be closed by removing solid wastes and contaminated soils (clean closure).

(b) The purpose of the plan for clean closure is to:

(1) establish a closure method for a disposal site that will partially or completely remove solid wastes and contaminated soils to provide remediation of a threat to public health and safety, reduce or eliminate the need for postclosure maintenance, prepare the site for postclosure land uses, or recover materials for recycling or reuse;

(2) provide a basis for the operator to establish an accurate detailed cost estimate for clean closure of the site; and

(3) provide a plan and schedule for the operator to implement at the time of closure.

(c) Each submittal shall be certified by a registered civil engineer or a certified engineering geologist. The minimum components of a plan for clean closure shall include, but not be limited to:

(1) a detailed implementation schedule for clean closure activities;

(2) a characterization of the site conditions to define the extent and character of wastes present and the levels and extent of any soil contamination;

(3) a description of the excavation and material management procedures to be followed;

(4) a description of health and safety procedures to be followed and specific measures to protect public health and safety during clean closure activities; and

(5) [Reserved].

(d) The plan for clean closure shall also include a detailed schedule for disbursement of funds for closure activities in accordance with § 21800(d).

(e) After clean closure activities are completed, a verification report confirming that waste and residual contaminated soils have been removed shall be prepared by a registered civil engineer or a certified engineering geologist and submitted for approval to the EA and the CIWMB. The report shall include the following information as appropriate:

(1) if the plan for clean closure was part of a remedial action, a description of any postclosure maintenance activities needed to comply with the implementation of the remedial action plan. In such cases the unit will not be deemed clean closed until completion of the corrective action.

(2) if all solid waste and contaminated soils are not removed, closure and postclosure maintenance plans and a financial assurances mechanism for closure and postclosure maintenance. Such a unit shall not be regarded as having been clean closed (see § 21090(f)).
