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. The plan of operation update will be considered a plan of operation modification, but shall follow the completeness, review times, and pre-plan of operation submittal public meeting requirements under s. NR 514.04. The plan of operation for all CCR landfills shall include all of the following: NR 514.07(10)(a)(a) A CCR fugitive dust control plan in accordance with all of the following: NR 514.07(10)(a)1.1. The plan shall identify and describe the CCR fugitive dust control measures the owner or operator will use to minimize CCR from becoming airborne at the facility. The owner or operator shall select and include in the CCR fugitive dust control plan the CCR fugitive dust control measures that are most appropriate for site conditions, along with an explanation of how the measures selected are applicable and appropriate for site conditions. Control measures may include any of the following: NR 514.07(10)(a)2.2. The plan shall include procedures to wet CCR with water to a moisture content that will prevent wind dispersal but will not result in free liquids. In lieu of water, wetting of CCR may be accomplished with an appropriate chemical dust suppression agent. NR 514.07(10)(a)3.3. The plan shall include a description of the procedures the owner or operator will follow to periodically assess the effectiveness of the control plan. At a minimum, the assessment shall include a visual inspection at least every 7 days, unless the CCR landfill is inactive and all areas are covered by intermediate or final cover. NR 514.07(10)(a)4.4. The plan shall be modified in accordance with s. NR 514.04 (6) whenever there is a change in conditions that may substantially affect the plan of operation. NR 514.07 NoteNote: The requirements under par. (a) apply in addition to, not in place of, any applicable standards under the federal Occupational Safety and Health Act.
NR 514.07(10)(b)(b) A run-on and run-off control system plan that includes all of the following: NR 514.07(10)(b)2.2. Plan sheets depicting the location of run-on and run-off control features, detail drawings, and supporting engineering calculations. NR 514.07(10)(b)4.4. Modification every 5 years from the date of the most recent plan approval or whenever there is a change in conditions that may substantially affect the written plan in effect. The modification shall be requested by the owner or operator in accordance with s. NR 514.04 (6) prior to the 5-year deadline.
