NR 514.07(9) (9) 

NR 514.07(9)(a) (a) The plan of operation for all new and expanded municipal solid waste landfills submitted to the department after January 1, 2007 shall include a plan for significantly reducing the amount of degradable organic material remaining after site closing in order to materially reduce the amount of time the landfill will take to achieve landfill organic stability. Owners and operators of all municipal solid waste landfills that have a plan of operation approved between January 1, 2004 and January 1, 2007 shall submit a plan modification to the department no later than January 1, 2007 for significantly reducing the amount of degradable organic material remaining after site closing in order to materially reduce the amount of time the landfill will take to achieve landfill organic stability. Owners and operators of all other municipal solid waste landfills at which filling has not exceeded 50% of the landfill’s approved capacity by January 1, 2012, shall submit a plan modification to the department no later than January 1, 2012, for significantly reducing the amount of degradable organic material remaining after site closing in order to materially reduce the amount of time the landfill will take to achieve landfill organic stability. Waste that has already been disposed of prior to the date the plan is approved by the department is not subject to the planning requirement, but may be included in the plan at the discretion of the landfill operator.

NR 514.07 Note Note: “Closing” is defined in s. 289.01 (5), Stats., as “the time at which a solid or hazardous waste facility ceases to accept wastes, and includes those actions taken by the owner or operator to prepare the facility for long-term care and to make it suitable for other uses.”

NR 514.07(9)(b) (b) Landfill organic stability plans required by this subsection shall include the following information:

NR 514.07(9)(b)1. 1. An overview of the plan.

NR 514.07(9)(b)2. 2. An initial analysis of the composition and quantity of materials that will be accepted by the landfill, including a classification of organic materials and percentage of organically inert materials, and a description of how the analysis was performed.

NR 514.07(9)(b)3. 3. A description of measures to be undertaken by the landfill owner or operator, or by others, including diversion to non-landfill management of organic material, pre-landfill mechanical or biological treatment of organic material, or in-landfill treatment of organic material, that will significantly reduce the amount of degradable organic material remaining after site closing and shorten the time the landfill will take to achieve landfill organic stability.

NR 514.07(9)(b)4. 4. A schedule for implementing the plan.

NR 514.07(9)(b)5. 5. The anticipated outcome of implementing the plan, relative to the landfill organic stability goals in par. (c) and the definition of landfill organic stability in s. NR 500.03 (120g).

NR 514.07(9)(b)6. 6. A description of how the effectiveness of the implemented plan will be monitored and evaluated. Plans shall include a description of the methods that will be used to monitor and evaluate the progress of the facility in implementing the plan, and measurements or milestones to be used in evaluating progress towards the goals in par. (c) and the plan’s anticipated outcome.

NR 514.07(9)(b)7. 7. A contingency plan outlining measures to be taken if periodic evaluation of the landfill organic stability efforts indicate the facility is unlikely to achieve the goals in par. (c).

NR 514.07(9)(c) (c) The objective of landfill organic stability plans is achievement of all of the measured goals in subds. 1. to 4. The department may not interpret the goals in subds. 1. to 4. as enforceable environmental quality standards:

NR 514.07(9)(c)1. 1. A monthly average total methane plus carbon dioxide gas production rate less than or equal to 5% of the maximum monthly average total gas production rate observed during the life of the facility, or less than 7.5 cubic feet of total gas per year for each cubic yard of waste in the facility.

NR 514.07(9)(c)2. 2. A steady downward trend in the rate of total methane plus carbon dioxide gas production.

NR 514.07(9)(c)3. 3. Production of total methane plus carbon dioxide gas cumulatively representing 75% or greater of the projected total gas production of the landfilled waste.

NR 514.07(9)(c)4. 4. Reduction of the time necessary to reach landfill organic stability to 40 years or less after site closing.

NR 514.07(9)(d) (d) The landfill owner or operator shall continually evaluate the performance of the implemented landfill organic stability plan, and report progress, results, changes in waste composition and problems to the department no less frequently than annually. The first annual report is due 12 months after the department’s approval of the landfill organic stability plan. The department may approve an alternative reporting schedule. Each annual report shall include an evaluation of whether changes are needed in the plan to correct problems or improve results. In addition, the landfill owner or operator may update the contingency plan.

NR 514.07(9)(e) (e) The landfill owner or operator shall examine progress against the approved plan every 5 years to evaluate the likelihood that the plan will enable the facility to reach the goals in par. (c), and determine whether the contingency plan in par. (b) 7. will be implemented. A report describing the evaluation and determination shall be submitted to the department as part of the annual report for that year. The department may require that the contingency plan be implemented if its review finds that the progress the landfill has made is significantly different than the approved plan.

NR 514.07(9)(f) (f) If the landfill owner or operator submits the landfill organic stability plan as a modification to an existing plan of operation, the department shall either approve or disapprove the plan modification in writing within 90 days after submission of a complete plan. If the landfill organic stability plan is included by the operator as part of a new plan of operation, the review times in s. NR 514.04 (5) shall apply.

NR 514.07(10) (10) Additional requirements for CCR landfills. The owner or operator of a new or existing CCR landfill or lateral expansion of a CCR landfill shall update the plan of operation every 10 years during the landfill’s active life to comply with regulations in place at the time of the update.
