Operating criteria.

(1) Procedures for excluding the receipt of prohibited waste.
(a) Owners or operators of all MSWLF units must implement a program at the facility for detecting and preventing the disposal of prohibited wastes. This program must include, at a minimum:
(i) Random inspections of incoming loads unless the owner or operator takes other steps (for example, instituting source controls and restricting the type of waste received) to ensure that incoming loads do not contain prohibited waste;
(ii) Records of any inspections;
(iii) Training of facility personnel to recognize prohibited wastes; and
(iv) Immediate notification of the department and the jurisdictional health department if a prohibited waste is discovered at the facility.
(b) For purposes of this subsection:
(i) "Prohibited waste" means a solid waste that is:
(A) A dangerous waste as defined in WAC 173-303-040 that is not excluded from regulation as a dangerous waste under WAC 173-303-071 or 173-303-073, or was not generated by an exempted small quantity generator as defined in WAC 173-303-070;
(B) Polychlorinated biphenyls (PCBs) regulated under Title 40 C.F.R. Part 761, Polychlorinated Biphenyls (PCBs) Manufacturing, Processing, Distribution in Commerce, and Use Prohibition; and
(C) Asbestos not managed in accordance to 40 C.F.R. Part 61.
(ii) "Random inspection" means:
(A) Discharging a random waste load onto a suitable surface. A suitable surface must be chosen to avoid interference with operations so that sorted waste can be distinguished from other loads of uninspected waste, so as to avoid litter and to contain runoff;
(B) Viewing the contents prior to actual disposal of the waste; and
(C) Allowing the facility owner or operator to return excluded wastes to the hauler, arrange for disposal of excluded wastes at a facility permitted to manage prohibited waste, or take other measures to prevent disposal of the excluded wastes at the facility.
(2) Cover material requirements.
(a) Except as provided in (b) of this subsection, the owners or operators of all MSWLF units must cover disposed solid waste with six inches (fifteen centimeters) of earthen material, i.e., soils, at the end of each operating day, or at more frequent intervals if necessary, to control disease vectors, fires, odors, blowing litter, and scavenging.
(b) Alternative materials of an alternative thickness other than at least six inches (15 centimeters) of earthen material may be approved by the jurisdictional health department. The owner or operator must demonstrate during the permit process of WAC 173-351-700 or through the permit modification process of WAC 173-351-720(6) that the alternative material and thickness will not present a threat to human health or the environment; will not adversely affect gas or leachate composition or collection; will control disease vectors, fires, odors, blowing litter, and scavenging; and provide adequate access for heavy vehicles.
(c) The jurisdictional health department may grant a temporary waiver not to exceed three months from the requirement of (a) and (b) of this subsection if the owner or operator demonstrates that there are extreme seasonal climatic conditions that make meeting such requirements impractical.
(3) Disease vector control.
(a) Owners or operators of all MSWLF units must prevent or control on-site populations of disease vectors using techniques appropriate for the protection of human health and the environment.
(b) For purposes of this subsection, "disease vectors" means any rodents, flies, mosquitoes, or other animals, including insects, capable of transmitting disease to humans.
(4) Explosive gases control.
(a) Owners or operators of all MSWLF units must ensure that:
(i) The concentration of methane gas generated by the facility does not exceed twenty-five percent of the lower explosive limit for methane in facility structures (excluding gas control or recovery system components);
(ii) The concentration of methane gas does not exceed the lower explosive limit for methane at the facility property boundary or beyond; and
(iii) The concentration of methane gases does not exceed one hundred parts per million by volume of methane in offsite structures.
(b) Owners or operators of all MSWLF units must control explosive gases and implement a routine methane monitoring program to ensure that the standards of (a)(i) and (ii) of this subsection are met.
(i) The explosive gas controls and type and frequency of monitoring must be determined based on the following factors:
(A) Soil conditions;
(B) The hydrogeologic conditions surrounding the facility;
(C) The hydraulic conditions surrounding the facility;
(D) The location of facility structures and property boundaries; and
(E) The design and operation of the MSWLF unit.
(ii) The minimum frequency of monitoring must be quarterly.
Note:
All gas monitoring wells must be constructed and decommissioned to ensure protection of the groundwater and to prevent groundwater contamination and follow the requirements of chapter 173-160 WAC, Minimum standards for construction and maintenance of wells, unless otherwise approved by the department and the jurisdictional health department.
(c) If methane gas levels exceeding the limits specified in subsection (4)(a)(i) or (ii) of this section are detected, the owner or operator must:
(i) Immediately take all necessary steps to ensure protection of human health including:
(A) Notifying the jurisdictional health department;
(B) Where subsection (4)(a)(ii) of this section is exceeded, monitoring of offsite structures for compliance with subsection (4)(a)(iii) of this section;
(C) Daily monitoring of methane gas levels unless otherwise authorized by the jurisdictional health department; and
(D) Evacuation of buildings affected by landfill gas must be determined by the jurisdictional health department and fire department.
(ii) Within seven calendar days of detection, place in the operating record, the methane gas levels detected and a description of the steps taken to protect human health; and
(iii) Within sixty days of detection, implement a remediation plan for the methane gas releases, place a copy of the plan in the operating record, and notify the jurisdictional health department that the plan has been implemented. The plan must describe the nature and extent of the problem and the remedy.
(iv) The jurisdictional health department may establish alternative schedules for demonstrating compliance with (c)(ii) and (iii) of this subsection.
(d) For purposes of this subsection, "lower explosive limit" means the lowest percent by volume of a mixture of explosive gases in air that will propagate a flame at twenty-five degrees C and atmospheric pressure.
(5) Air criteria.
(a) Owners or operators of all MSWLF units must ensure that the units not violate any applicable requirements developed under the Washington state implementation plan approved or promulgated by the U.S. Environmental Protection Agency pursuant to Section 110 of the Federal Clean Air Act, as amended.
(b) Open burning of solid waste is prohibited at all MSWLF units, except: For the infrequent burning of agricultural wastes, silvicultural wastes, landclearing debris, diseased trees or debris from emergency cleanup operations, provided that such open burning is not inconsistent with policies, regulations, and permits administered by the jurisdictional air pollution control agency or the department under the Washington Clean Air Act, chapter 70.94 RCW. Household waste must not be open burned.
(6) Access requirements. Owners or operators of all MSWLF units must control public access and prevent unauthorized vehicular traffic, illegal dumping of wastes, and controls to keep animals out by using artificial barriers, natural barriers, or both, as appropriate to protect human health and the environment. A lockable gate is required at each entry to the facility.
(7) Run-on/runoff control systems.
(a) Except as allowed under WAC 173-351-710, owners or operators of all MSWLF units must design, construct, and maintain:
(i) A run-on control system to prevent flow onto the active portion of the landfill during the peak discharge from a twenty-five year storm;
(ii) A runoff control system from the active portion of the landfill to collect and control at least the water volume resulting from a twenty-four hour, twenty-five year storm.
(b) Runoff from the active portion of the landfill unit must be handled in accordance with WAC 173-351-200(8).
(8) Surface water requirements. MSWLF units must not:
