21. The owner and the operator of a landfilling site shall ensure that, (a) within three months after each anniversary of the date on which waste was first accepted at the site, an annual report is prepared respecting the operation of the landfilling site, including a summary of results from monitoring programs; and (b) all of the reports are retained until at least two years after the site is closed.  O. Reg. 232/98, s. 21. Burning

22. (1) The owner and the operator of a landfilling site shall ensure that no municipal waste is burned at the site as part of the landfilling operation.  O. Reg. 232/98, s. 22 (1).

Reg. 232/98, s. 22 (2). Scavenging

23. The owner and the operator of a landfilling site shall ensure that there is no scavenging at the site.  O. Reg. 232/98, s. 23. Surface Water Monitoring

24. The owner and the operator of a landfilling site shall ensure that a program is carried out for monitoring the quality and quantity of the surface water features on the site and of the surface water features that receive a direct discharge from the site.  O. Reg. 232/98, s. 24. Ground Water Monitoring

25. The owner and the operator of a landfilling site shall ensure that a program is carried out for monitoring ground water quality and quantity.  O. Reg. 232/98, s. 25. Leachate Monitoring

26. The owner and the operator of a landfilling site shall ensure that a program is carried out for monitoring leachate quality and quantity.  O. Reg. 232/98, s. 26. Leachate Contingencies

27. (1) The owner and the operator of the landfilling site shall ensure that investigative activities are carried out with respect to the cause of an increase in contaminant concentrations if any of the trigger criteria described under paragraph 5 of subsection 12 (2), as they may have been modified under paragraph 2 of subsection (3) of this section, is exceeded for any single monitoring event. O. Reg. 232/98, s. 27 (1). (2) The owner and the operator of the landfilling site shall ensure that the steps described in subsection (3) are taken if the investigative activities required by subsection (1) indicate that, (a) the potential exists for a liner or leachate collection system to fail or for leachate to otherwise leave the waste fill zone in a quantity greater than expected or with a quality worse than expected; (b) the potential exists to exceed any maximum allowable contaminant concentration described under paragraph 2 of subsection 12 (2); (c) an expected contaminant level predicted by studies and modelling previously carried out under paragraph 4 of subsection (3) has been exceeded; or (d) the highest previous observation of the background concentration of a contaminant in the ground water of the receptor aquifer has been exceeded, if studies and modelling have not previously been carried out under paragraph 4 of subsection (3).  O. Reg. 232/98, s. 27 (2). (3) The steps referred to in subsection (2) are the following: 1. Previously identified contingency measures must be reviewed and any necessary or desirable modifications made. 2. Previously identified trigger criteria must be reviewed and any necessary or desirable modifications made. 3. The monitoring programs for ground water, surface water and leachate must be reviewed and any necessary or desirable modifications made. 4. If they have not previously been carried out, studies and modelling that meet the following conditions must be carried out: i. The studies and modelling must provide predictions of expected contaminant concentrations at least annually for the contaminating life span of the site. ii. The studies and modelling must include predictions related to potential increases in contaminant concentrations in the ground water at the property boundary and in any surface water feature on the site, as well as at any ground water monitoring stations. 5. If studies and modelling described in paragraph 4 have previously been carried out, they must be reviewed and any necessary or desirable modifications made. 6. Implementation criteria for implementation of the contingency measures must be identified and the related activities and timing must be described.  O. Reg. 232/98, s. 27 (3). (4) If the monitoring results, investigative activities and implementation criteria indicate the need to implement contingency measures, the owner and the operator of a landfilling site shall ensure that the following steps are taken: 1. The Director must be notified of the need to implement contingency measures. 2. Detailed plans, specifications and descriptions for the design, operation and maintenance of the contingency measures must be prepared. 3. The contingency measures must be implemented.  O. Reg. 232/98, s. 27 (4). Daily Cover

28. (1) The owner and the operator of a landfilling site shall ensure that all waste accepted for disposal at the site is disposed of in the waste fill zone and is covered at the end of each working day by daily cover in accordance with this section.  O. Reg. 232/98, s. 28 (1). (2) The daily cover shall consist of soil, foundry sand, wood chips, compost or other material.  O. Reg. 232/98, s. 28 (2). (3) When tested using the Toxicity Characteristic Leaching Procedure, the daily cover must not produce leachate containing any of the contaminants listed in Schedule 4 to Regulation 347 of the Revised Regulations of Ontario, 1990 (General — Waste Management) made under the Act at a concentration equal to or in excess of the concentration specified in that Schedule for the contaminant.  O. Reg. 216/08, s. 3. (4) Subsection (1) does not apply to a landfilling site associated with forest products operations, such as the operations of a lumber mill, sawmill, pulp mill or similar facility, if the waste to be deposited at the site is produced by the forest products operations and is predominantly solid, non-hazardous process waste, such as woodwaste, effluent treatment solids, hog fired boiler ash, recycling process rejects, lime mud, grits or dregs.  O. Reg. 232/98, s. 28 (4). Final Cover

29. (1) The owner and the operator of a landfilling site shall ensure that the following materials are applied to the waste fill zone as final cover, from bottom to top: 1. A minimum of 0.6 metres of cover material. 2. A minimum of 0.15 metres of topsoil or other material approved by the Director as able to sustain plant growth. 3. A vegetative cover consisting of vegetation that is suited to local conditions and that is capable with minimal care of providing vigorous, plentiful cover not later than its third growing season.  O. Reg. 232/98, s. 29 (1). (2) The owner and the operator of a landfilling site shall ensure that the final cover is designed so that, (a) the infiltration rate through the final cover is in accordance with the design for the site respecting ground water protection prepared under section 10; (b) any existing or anticipated facilities for the control, collection, use or discharge of landfill gas are accommodated; and (c) the requirements for the end use of the site, as described in the site design report prepared under section 6 and the closure report prepared under section 31, are met.  O. Reg. 232/98, s. 29 (2). Final Slopes
