Section NR 506.07 - Operational requirements for landfillsNo person may operate or maintain a new or existing landfill except in conformance with any approved plan of operation and the following minimum requirements:
(1) GENERAL. (a) Daily disposal of solid waste shall be confined to as small an area as practical.(b) Provisions shall be made to confine windblown material within the active disposal area.(c) At the conclusion of each day of operation, all windblown material shall be collected and properly disposed of in the active area in accordance with the provisions of this section unless the operator establishes, to the satisfaction of the department, that all windblown material cannot be collected using reasonable efforts because of conditions beyond the control of the operator, and windblown material which can be collected using a reasonable effort has been collected and properly disposed and nuisance conditions do not exist.(d) Putrescible materials such as spoiled foods and animal carcasses shall be immediately compacted and covered.(e) Access to the landfill shall be restricted through the use of fencing, natural barriers or other methods approved in writing by the department.(f) Effective means shall be taken to limit access to the active disposal area to minimize exposure of the public to hazards.(g) Effective means shall be taken to control birds, flies, rodents, deer and other animals.(h) Equipment shall be provided to control accidental fires and arrangements shall be made with the local fire protection agency to acquire its services when needed.(i) As required in s. NR 524.05, a trained operator or certified facility manager shall be present at the landfill during all hours of operation, and a list of names of trained operators and certified facility managers shall be maintained at the landfill.(j) A gate shall be provided at the entrance to the operation and it shall be kept locked when an attendant is not on duty.(k) The gate area shall be policed at the beginning of each day of operation to remove any solid waste which has been indiscriminately dumped during periods when the landfill was closed. (l) A sign, acceptable to the department, shall be posted at the entrance of any landfill operated for public use which indicates the landfill name, license number, the hours of operation, waste types accepted, penalty for unauthorized use, necessary safety precautions and any other pertinent information.(m) The landfill shall be surrounded with rapidly growing trees, shrubbery, fencing, berms or other appropriate means to screen it from the surrounding area and to provide a wind break.(n) Fugitive dust shall be controlled in accordance with s. NR 415.04 from all areas of the landfill.(o) Scavenging within the active disposal area is prohibited.(p) Provisions shall be made for back-up equipment in the event of operating equipment breakdown.(q) A minimum separation distance of 20 feet shall be maintained between the limits of filling and adjacent property or the perimeter of the licensed acreage, whichever is closer at nonapproved facilities as defined in s. 289.01(24), Stats. At all other facilities, a minimum separation distance of 100 feet shall be maintained between the limits of solid waste filling and the property boundary or the perimeter of the licensed acreage, whichever is closer. The department may require additional separation distance if necessary to provide for vehicle access, drainage, monitoring, gas migration control, separation to adjacent homes or other landfill development factors.(r) All topsoil within the landfill construction limits shall be salvaged and stored within the property boundaries for use in landfill closure. All stockpiled soil material which is not anticipated to be used within 6 months shall be seeded.(s) All access roads to the active area of the operation shall be of all-weather construction and shall be maintained in good condition.(t) All access roads for the use of solid waste hauling trucks shall be constructed with a maximum grade no greater than 10%. The intersection of the access road with an existing highway shall be constructed to provide sufficient sight distance and minimize interference with traffic on existing highways.(2) SEDIMENTATION AND EROSION CONTROL. (a) All areas of the landfill property, including areas of temporary disturbance, with the potential for off-site migration of sediment shall be designed, constructed and maintained in accordance with the applicable requirements of s. NR 504.09(1), and technical standards developed under subch. V of ch. NR 151, which include the following: 1. Storm water shall be diverted away from the working area and areas already filled with solid waste.2. Storm water from upslope areas shall be diverted around disturbed areas to minimize erosion, entrained sediment and the amount of water contacting the disturbed area.3. The size and duration of disturbances shall be minimized, to the extent practicable, to minimize off-site sediment migration.4. While the site is disturbed, temporary measures shall be used to trap sediment and off-site sediment migration. This could include gravel breaks or the equivalent to minimize the transport of sediments offsite.5. Runoff channels shall be protected to prevent scour and erosion that generates sediment. Note: The technical standards developed by the Wisconsin department of natural resources, runoff management program are available at http://dnr.wi.gov/topic/stormwater/construction/erosion_control.html#7or can be obtained from the department of natural resources, bureau of waste management, 101 S. Webster Street, P.O. Box 7921, Madison, WI 53707-7921, (608) 266-2111, waste.management@dnr.state.wi.us. Copies are also available for inspection at the offices of the legislative reference bureau and the secretary of state.
(b) Storm water drainage ditches, structures and sedimentation basins shall be cleaned and maintained such that they properly control storm water and limit entrained sediment in accordance with approved engineering designs. The department may waive this requirement on a case by case basis for existing facilities.(c) All areas of the landfill which will not contain solid waste and are planned for vegetative cover shall be topsoiled, seeded and mulched as soon as practical, but no later than 90 days after completion of construction or by October 15, whichever is earlier and, if construction is completed after September 15, no later than June 15 of the following year. This includes, but is not limited to, the landfill entrance, drainage ditches and surrounding areas. Erosion control measures shall be placed within 30 days after completion of construction. The seed type and amount of fertilizer applied shall be selected according to: the type and quality of topsoil, it's compatibility with native vegetation and the final use. Unless otherwise approved by the department in writing, seed mixtures and applications rates shall be in accordance with section 630, Wisconsin department of transportation standard specifications for road and bridge construction. Note: Copies of Wisconsin department of transportation standard specifications for road and bridge construction can be obtained from the department of natural resources, bureau of waste management, 101 S. Webster street, Madison, Wisconsin 53707. Copies are also available for inspection at the offices of the legislative reference bureau and the secretary of state.
(3) WASTE PLACEMENT. (a) Disposal of solid waste shall begin at the edge of each phase. Waste shall be pushed out over the granular blanket. Vehicles may not be driven directly on the granular blanket. Alternative operating procedures may be approved by the department if the consistency of the solid waste prevents vehicular access over a filled area.(b) Except for portions of the sideslope greater than 10 feet above the base liner, a layer of solid waste at least 4 feet thick or an adequate amount of other frost protection material shall be placed over the granular blanket in all portions of the lined area prior to December 1st of the year following the year the clay portion of the liner was constructed. After this date, solid waste may not be placed on any portion of the base liner or lower 10 feet of the sideslope not covered with a 4-foot thick layer of solid waste or other adequate frost protection material. Those portions of the base liner or lower 10 feet of sideslope not covered with a 4-foot thick layer of solid waste or other frost protection material by this date shall be investigated for density and effects from freeze-thaw as specified by the department and shall be repaired and recertified during the next construction season if required, prior to waste placement. The requirements of this paragraph may be waived by the department.(c) To provide for maximum compaction after the initial 4-foot lift of waste is placed, each single layer of municipal solid waste shall be spread and compacted in 2-foot layers.(4) GAS CONTROL. Effective means shall be utilized to prevent the migration of explosive gases generated by the waste fill. At no time shall the concentration of explosive gases in any landfill structure, excluding the leachate collection system or gas control and recovery system components exceed 25% of the lower explosive limit for such gases. At no time shall the concentration of explosive gases in the soils outside of the limits of filling or air within 200 feet of or beyond the landfill property boundary exceed the lower explosive limit for such gases. The department may require the concentration of explosive gases not exceed detectable levels for that gas at the landfill property boundary.(5) LEACHATE COLLECTION SYSTEMS. (a) Leachate shall be removed from all collection tanks, manholes, lift stations, sumps or other structures used for leachate storage as often as necessary to allow for gravity drainage of leachate from the facility at all times or as it is produced, including hours when the landfill is closed, such as overnight and weekends. Unless the facility has received approval from the department to recirculate leachate or gas condensate derived from the landfill as provided in s. NR 506.13(2), all leachate removed from a leachate collection system shall be disposed of at a wastewater treatment facility approved by the department and capable of accepting the leachate in accordance with the requirements of its WPDES permit. The landfill owner or operator shall immediately notify the department of any change in the availability of the designated wastewater treatment facility to accept or dispose of the leachate removed from the landfill. Waste may not be accepted at the landfill unless leachate is being managed in accordance with landfill's approved plan of operation and the requirements of this section.(b) Any liquid which comes in contact with waste or accumulates in a portion of the landfill where active waste disposal operations are occurring shall be handled as leachate and properly treated as specified in par. (a) unless otherwise approved by the department in writing. (c) All leachate collection lines shall be cleaned with a water jet cleanout device with a maximum pressure of 10,000 pounds per square inch immediately after construction, and annually thereafter.(d) All leachate collection lines shall be cleaned with water jet cleanout devices initially after placement of the leachate drain layer using pipe cleaning procedures that insert cleanout devices from each access point to, at a minimum, the toe of the opposite sideslope.(e) A video camera inspection shall be conducted on all leachate collection pipes after the initial pipe cleaning activities required in par. (d) and at 5 year intervals, following the annual pipe cleaning required in par. (c). The video camera inspection shall extend a minimum of 300 feet unto the base grades of each leachate collection line.(f) All blockages of leachate collection pipes, pipe breaks or any impedances to passage of pipe cleaning equipment shall be investigated, defined and a remediation proposed for review and approval by the department.(g) A summary report shall be submitted after each pipe cleaning and each video camera inspection event. The report shall summarize any specialty equipment or chemicals used in collection pipe cleaning. The report shall include a description of all observations, including recording tape or disk of the video camera inspection. The report shall summarize the investigation of blockages or other difficulties in cleaning pipes. The report shall propose remediation if the leachate collection pipes are not restored to function and blockages are not cleared.(h) A summary report shall be submitted after the removal of dams or barriers used to separate clean water in a prepared cell from solid waste and leachate. The report shall document the removal of the separation features and the connection of any separated pipe lengths.(7) PHASED CLOSURE. For all landfills that do not have a department-approved plan for phased development and closure, by October 15th of each year, any areas that are at final grades shall be capped, topsoiled and seeded unless otherwise approved by the department.Wis.
