The landfill operator shall maintain in the landfill's written operating record the liquid mass balance for each leachate drainage basin, including leachate extracted, leachate recirculated and precipitation, in all areas where leachate is recirculated, in accordance with the requirements of s. NR 507.215

Leachate application shall be limited to the active area of the landfill.
Leachate may not be applied during wet or windy conditions that would prevent containment of the leachate to the application area.
Truck traffic shall be routed around the application area until the application area is covered to prevent tracking of leachate.
Areas of the landfill where leachate has been applied shall be covered with newly placed waste or soil as soon as possible, but in no case later than the end of the same working day that leachate is applied.
(3) Vertical distribution systems.
Vertical distribution systems shall comply with the following requirements in addition to those in sub. (1)

Leachate shall not be discharged continuously to individual distribution pipes. Periodic rest periods shall be incorporated into the operating schedule to allow for absorption of leachate into the waste mass and for extraction of landfill gas.
Landfill gas may be extracted through leachate distribution pipes to supplement the permanent gas extraction system.
(5) Annual reporting for leachate recirculation.
An annual report shall be submitted to the department by April 30 of each year for leachate recirculation activities occurring during the previous calendar year. The report shall include:
The results of the liquid mass balance measurements for each leachate drainage basin.
Graphs showing the volumes of leachate extracted and recirculated and precipitation received for each leachate drainage basin.
Graphs over the time period since leachate recirculation was initiated, for each parameter required to be sampled in s. NR 507.215
Summary of warning symptoms, terminations, resumptions of leachate recirculation after termination, and any operating problems and resolutions.
Documentation drawings or diagrams showing the installed details of the leachate distribution system added or revised since the previous annual report, including but not limited to piping, pumps and distribution media.

Procedures for excluding the receipt of waste not specifically approved for acceptance at the landfill.
Owners and operators of landfills that accept municipal solid waste shall implement a program at the landfill for detecting and preventing the disposal of waste not specifically approved for acceptance including but not limited to liquids, sludges, regulated hazardous waste and PCB waste. The program shall include the following:
(1) Random inspections of incoming loads.
Random inspections shall be made of every incoming load of solid waste unless the owner or operator receives approval in writing from the department to take other steps to insure that incoming loads do not contain wastes not specifically approved for acceptance.
Inspections shall be conducted on every 5,000 tons of solid waste accepted or one inspection per month, whichever is more frequent. No more than one inspection per week is required. An owner or operator of a landfill which accepts less than 10,000 tons per year of solid waste and demonstrates adequate justification for less frequent inspections may be approved by the department for a minimum of 4 inspections per year. To assure that the inspections are random, the first truckload which exceeds the accumulated total of 5,000 tons of solid waste shall be selected for inspection. Alternate methods of assuring random selection may be approved by the department.
The inspection shall involve discharging the waste load and viewing its contents in an area that clearly segregates the waste from all other solid wastes and is capable of controlling any potentially hazardous waste prior to disposal of the waste.
(2) Records of inspections.
Records of the random load inspections shall include the following information:
The names of the firm transporting the solid waste and the driver of the vehicle.
The vehicle's license plate and the transporter's Wisconsin solid waste license number.
The community or communities where the solid waste was generated.
The type or types of waste such as commercial, industrial, residential or any combination.
The name of the certified facility manager or certified site operator inspecting the load.
All of the observations made by the inspector, including any actions taken to manage or return nonapproved waste or actions taken if extreme toxicity or hazard is discovered.
(3) Training of landfill personnel to recognize waste not approved for acceptance.
Landfill personnel shall be trained in accordance with ch. NR 524
to recognize waste not approved for acceptance.
(4) Notification if a waste not approved for acceptance is discovered at the landfill.
The owner or operator of the facility shall notify the department's district or area solid waste management specialist in writing within 15 days if non-hazardous waste not approved for acceptance is discovered at the landfill. If waste not approved for acceptance is discovered and is suspected of being hazardous or containing PCBs at a concentration of 50 ppm or greater, the owner or operator of the facility shall notify the department's district or area solid waste and hazardous waste management specialists in writing within 2 days.
(5) Rejection of waste not approved for acceptance.
Waste which is not approved for acceptance at the landfill shall be rejected. The waste shall be handled in accordance with all applicable regulations including but not limited to transportation, storage, treatment and disposal.

The certification, shall be prepared and signed by the owner or operator of the landfill, certified facility manager, solid waste manager or person most directly responsible for the landfill's day to day operation. The signer shall certify that he or she is aware of all approved plans for the landfill, all department conditions of approval, and all applicable solid waste statutory and administrative rules, and that to the best of the signer's knowledge, information and belief, the landfill is or is not in substantial compliance with all approved plans and requirements. For landfills which are in full compliance, no narrative is required beyond the certification statement. For other landfills, all known areas of noncompliance shall be clearly indicated. This subsection does not impose personal liability upon certified facility managers or certified site operators.
As specified under s. 289.91
, Stats., the department may perform audits of any landfill. Following a minimum 30-day advance notification, the landfill owner or operator shall ensure that during the period of the audit, a conference room or adequate office space is provided for department personnel, and that proper technical personnel representing the owner are present to respond to department inquiries regarding the landfill. The owner or operator shall also ensure that any of the information in pars. (a)
or any other information specified by the department in its audit notification letter is available in an organized fashion for the department to review. The owner or operator shall provide copies of requested information for the department to take with them following the audit.
