    (2) Maintaining the integrity and effectiveness of the access road and blocking of entrances, the cap system, and stability of the landfill, including making repairs to the cap system as necessary to correct the effects of slope failure, settling, subsidence, ponding, erosion, leachate outbreaks, or other events, and preventing run-on and runoff from eroding or otherwise damaging the access road or cap system. If vegetative cover is established on less than seventy-five per cent of the cap system, the owner or operator shall reseed and if appropriate, amend the soil.

    (3) Maintaining signs stating that the sanitary landfill facility no longer accepts solid waste for two years after final closure activities have been completed.

    (4) Continuing operation and maintenance of the leachate management system including the following:

    (b) If leachate generation suddenly decreases, visually or physically inspecting the collection pipe network of the leachate management system to ensure that clogging has not occurred.

    (c) For a sump serving a leachate collection system across the bottom of the landfill, maintaining leachate no more than one foot above the top elevation of the sump. Leachate may be stored within the limits of waste placement if authorized in writing by the director.

    (5) Repairing any leachate outbreaks detected at the sanitary landfill facility through completion of the following:

    (a) Containing and properly managing the leachate at the sanitary landfill facility.

    (b) If necessary, collecting, treating, and disposing of the leachate including following the contingency plan for leachate storage and disposal prepared pursuant to rule 3745-27-19 of the Administrative Code.

    (c) Taking action to minimize, control, or eliminate the conditions that contribute to the production of leachate.

    (6) Quarterly inspection of the sanitary landfill facility during each year of the post-closure care period and submittal of a written summary to the appropriate Ohio EPA district office and approved board of health not later than fifteen days after the inspection date detailing the results of the inspection and a schedule of any actions to be taken to maintain compliance with paragraphs (A)(1) to (A)(5) of this rule. At a minimum, the quarterly inspection shall assess the condition and operation of the following:

    (a) The surface water management system.

    (b) The gas management system.

    (c) The access road and access controls.

    (d) For the initial three years of post-closure care, signage.

    (e) The cap system and vegetative cover including any occurrences of settling, subsidence or other effects of slope failure, ponding, erosion, or leachate outbreaks.

    (f) The leachate management system including leachate depth in the sump.

    (7) Fulfilling the monitoring and reporting requirements in accordance with rule 3745-27-10 of the Administrative Code for ground water, rule 3745-27-12 of the Administrative Code for explosive gas, Chapter 3745-76 of the Administrative Code for landfill emissions, and any monitoring and reporting requirements in accordance with any orders or authorizing documents. The frequency of ground water detection monitoring sampling and analysis may be changed in accordance with paragraph (D)(6) of rule 3745-27-10 of the Administrative Code.

    (8) If a substantial threat of water pollution exists from leachate entering surface waters, monitoring of the surface water as required by the director or health commissioner.

    (9) Submitting a report to the appropriate Ohio EPA district office and approved board of health and placing a copy into the operating record not later than the first day of April of each year. At a minimum, the report shall contain the following:

    (a) If a leachate collection system exists, a summary of the quantity of leachate collected for treatment and disposal on a monthly basis during the year, the location of leachate treatment or disposal, and copies of all testing results performed for disposal.
