Pursuant to the Environmental Protection Act one or more of the following: Impairment to the quality of the natural environment for any use that can be made of it; Injury or damage to property or plan or animal life; Harm or material discomfort to any person; An adverse effect on the health of any person; Impairment of the safety of any person; Rendering any property of plant or animal life unfit for human use; Loss of enjoyment or normal use of property; and Interference with normal conduct of business. The AERMOD model is an advanced dispersion model that has been approved for use in Ontario by the Ministry of the Environment (MOE). AERMOD is a steady-state Gaussian model that is capable of handling multiple emission sources. Within the model, receptor grids as well as discrete receptor locations of interest can be considered. The modelling assessment was conducted in accordance with MOE s Guideline A11: Air Dispersion Modelling Guideline for Ontario, March For stationary sources, the release or discharge of a pollutant from a facility or operation into the ambient air either by means of a stack or as a fugitive dust, mist or vapour. Feasible alternative ways of implementing or carrying out the preferred solution to the identified problem or opportunity. Functionally different ways of solving an identified problem or addressing an opportunity that is considered feasible, from which a preferred solution is identified. Ontario Regulation 337 Ambient Air Quality Criteria defined limits for specific compounds for defined under the Ontario Regulation Point of Impingement Standards and Guidelines. All noises that exist in an area and are not related to a facility under study. Ambient noise may include sound from other existing industrial facilities, transportation sources, animals, and nature. Context for ambient noise should be defined for each project. Permission granted by an authorized individual or organization for an undertaking to proceed. This may be in the form of an Environmental Compliance Approval (ECA). 5

6 Approved Site or Facility Aquifer Aquitard Archaeological Resource Area of Natural and Scientific Interest (ANSI) Baseline Bedrock Berm Best Management Practices (BMP) Biological Diversity / Biodiversity Borehole Buffer Area / Zone Built Heritage Feature Canada Land Inventory (CLI) Canadian Environmental Assessment Act (CEAA) 2012 A landfill site or waste management facility with a current valid A soil or rock formation, group of formations or part of a formation that contains sufficient saturated permeable material to yield economical quantities of water to wells and springs. A confining bed of low permeability along an aquifer that impedes but does not prevent the flow of water to or from an adjacent aquifer. Any material remains of past human life or activity which are of archaeological interest. An area of land and water that represents significant geological and biological features. Refers to the existing air quality surrounding the landfill before the proposed expansion. The baseline is used to determine if there will be a change in the existing environment before the proposed expansion. Bedrock is the rock that underlies the soil; it can be permeable or non-permeable. An earthen embankment or wall, erected to provide protection from the weather; to act as a landscaping screen; or to act as a mitigative measure against visual and noise impacts. A technique or methodology that, through experience or research, has been proven to reliably lead to a desired result. After researching all known management methods, the selection and adaptation of the most suitable practices for achieving the desired outcome. The diversity of plant and animal life in a particular area (e.g., habitat, city, world). A hole drilled to construct a well. In a landfill context, the area between the edge of the waste and property boundary, established to provide space for remedial measures, for the reduction or elimination of adverse environmental impact, and for monitoring. A site with one or more significant buildings, structures, monuments, installations or remains associated with architectural, cultural, social, political, economic or military history and identified as being important to a community. A land classification scheme and mapping which distinguishes all rural land in Canada. The purpose of the Act is to ensure that projects are considered in a careful manner before federal authorities take action in connection with them, in order that such projects do not cause significant adverse environmental effects. In addition, the Act encourages the promotion of sustainable development in federal decision making and public participation in the environmental assessment process. 6

The discharge of chloride from the waste to surface water. CLI defines soils in this class have moderate limitations that restrict the range of crops or require moderate conservation practices. The soils are deep and hold moisture will. The limitations are moderate and the soils can be managed and cropped with little difficulty. Under good management they are moderately high to high in productivity for a fairly wide range of crops. CLI defines soils in this class have moderately severe limitations that restrict the range of crops or require special conservation practices. The limitations are more severe than for class 2 soils. They affect one or more of the following practices: timing and ease of tillage, planting and harvesting, choice of crops, and methods of conservation. Under good management they are fair to moderately high in productivity for a fair range of crops. Landfill that is in the business of accepting and disposing of hazardous waste from customers. Compensation refers to measures that are designed to counterbalance the loss of use or value of a particular parcel of land.

9 Environmental Assessment (EA) Environmental Assessment Act (EAA) Environmental Compliance Approval (ECA) Environmental Effect Environmental Protection Act (EPA) Equalization Reservoir Evaluation Criteria Existing Conditions Existing Land Uses Extended Site Life A systematic process that is conducted in accordance with applicable laws or regulations aimed at assessing the effects of a proposed undertaking on the environment. Includes evaluation of rationale and opportunity, alternatives, impacts, and mitigative, remedial, and/or monitoring measures. The purpose of the EAA is to provide for the: protection; conservation; and, wise management of Ontario s environment. To achieve this, the EAA ensures that environmental problems or opportunities are considered and their effects are planned for before development or building takes place. An Environmental Compliance Approval (ECA) is required under Part V, Section 27 of the Environmental Protection Act to establish a waste management system or a waste disposal site. This is the licence granted by the regulating agency which permits the operation of the landfill by the applicant or its agents. In Ontario, ECAs are granted by the Ontario Ministry of the Environment (MOE). The ECAs often specify numerous conditions which must be obeyed in order to retain approval to operate the landfill or waste processing facilities. An ECA is required before a waste disposal management system or a waste disposal site can be used, operated, established, altered, enlarged or extended. Any change, whether positive or negative, that an undertaking (project) may cause in the environment. An Ontario Act to provide for the protection and conservation of the natural environment. Treated surface water (also referred to as treated effluent ) is discharged to, and retained in the equalization reservoir prior to release off-site. Evaluation criteria are considerations or factors taken into account in assessing the advantages and disadvantages of various alternatives being considered. The existing conditions that are the physical, chemical, biological, social, economic, and cultural setting in which the proposed project is to be located and where local impacts (both positive and negative) might be expected to occur. In the context of the Environmental Assessment process, existing land uses refer in broad terms to the ways in which lands in the study area are currently being used or occupied. This information is compiled through mapping and verified through field surveys. The landfill might operate beyond the 25 year planning period if actual waste volumes received annually at the landfill might be lower than the volumes predicted. 9

10 Final Cover First Nation Fugitive Emissions Generator A cap constructed over the completed surface of a landfill, usually composed of soil, but sometimes also incorporating synthetic membranes. The cover serves several purposes including: a physical barrier to prevent contact with buried wastes, reducing the infiltration of rain into the waste (to limit the production of leachate) and controlling the escape of any gasses into the atmosphere. Another aspect in designing the final cover is to make it compatible with the ultimate enduse of the site. Although the term First Nation is widely used, no legal definition of it exists. Among its uses, the terms "First Nations people" refers to the Indigenous people in Canada who are not Inuit or Métis, both Status and Non-Status. Some Indigenous people also use the term First Nation to replace the word "band" in the name of their community. Emissions not caught by a capture system. Any person, by site, who through ownership, management, operation or control, creates or stores wastes. Generators include operators of commercial and manufacturing facilities that produce wastes as well as operators of commercial manufacturing facilities that produce waste as well as operators of waste disposal, transfer, bulking, treatment or processing facilities that forward materials off-site. Good Neighbours Program The Good Neighbours Program forms one of the commitments presented in the documentation of the approved 1996 EA for landfill service continuation. The intent of the Good Neighbours Program is to enhance a long lasting positive relationship between Clean Harbors and local residents. Components of this program include minimizing or eliminating impacts of the facility s operations on neighbours, ongoing communication, timely and active response to complaints, annual one-on-one discussion with Eligible Property Owners, Damage Claims Resolution Plan for damages attributable to the facility, and a Property Value Protection Plan which ensures Eligible Property Owners receive fair market value when they sell their property. Groundwater Habitat The mass of water in the ground below the unsaturated zone, occupying the total pore space in the soil or rock. The physical location or type of environment in which an organism or biological population occurs or lives, grows, and carries out life processes. Haul route Hazardous Waste Private and/or public roadway(s) used by vehicles transporting waste to and from a landfill site. By-products of society that can pose a substantial or potential hazard to human health or the environment when improperly managed. Possesses at least one of four characteristics (ignitability, corrosivity, reactivity, or toxicity). 10

11 Hazardous Waste Landfill Household Hazardous Waste Hazardous waste landfills, also known as secure landfills, afford safe hazardous waste disposal by providing a high degree of containment of landfill leachate through increased separation between the landfilled waste and the underlying bedrock or groundwater. See Municipal Hazardous and Special Waste. Hydraulic Conductivity (K) Hydraulic conductivity, symbolically represented as K, is a constant which describes the rate of movement of water through pore spaces or fractures in soil or rock. For example, the lower the hydraulic conductivity, the lower the amount of water that will be conducted. Hydraulic conductivity depends on the intrinsic permeability and the degree of saturation of a material. Saturated hydraulic conductivity describes water movement through saturated media.

In chemistry, relating to compounds not containing hydrocarbon groups. The zone of hydraulic activity, in which the Basal Till, where present, and the upper of the shale bedrock where fractured, have a comparatively high hydraulic conductivity and have been exploited regionally and locally as a source of water supply. 11

12 Land Disposal Restrictions (LDR) Landfill Landfill Standards Guideline Land Use Designation Leachate Leachate Collection System (LCS) Leachate Mounding Liquid Industrial Wastes Listed Wildlife Species Locally Significant Wetland Ministry of the Environment (MOE) Ontario Mitigation Through an amendment of Ontario Regulation 347, the land disposal restriction prohibits the land disposal of certain wastes unless the waste meets specific treatment standards to reduce the mobility and/or toxicity of its hazardous components. Landfill is a waste disposal site where waste is spread in layers, often compacted to the smallest practical volume, and typically covered by soil. The Ontario Ministry of the Environment Landfill Standards Guideline describes the regulatory and approval requirements for the design, operation, closure and post-closure care of new or expanding municipal (i.e. non-hazardous) waste landfilling sites. Regulatory requirements are contained in Ontario Regulation 232/98 made under the Environmental Protection Act. A land use designation in an Official Plan or Community Design Plan describes an area of land within which a specific set of policies applies. The policies identify the main objective of the designation and provide a framework for making land use decisions in the area that is covered by the designation. Water that collects contaminants as it trickles through wastes, pesticides or fertilizers. Leaching may occur in farming areas, feedlots, and landfills, and may result in hazardous substances entering surface water, ground water, or soil. An engineered system to control and collect leachate within a landfill. It is usually constructed of a combination of wells, coarse drainage layers, pipes and/or pumps. The height of landfill leachate that builds up naturally within the level dependent on the water level in the surrounding soils and the operation of the leachate collection system. Clogging or failure of the leachate collection system can cause an increase in leachate mounding. Liquid wastes that come from industrial or commercial sources. They include spent acid solutions, photoprocessing wastes, emulsified oils, waste oils and lubricants as well as many other waste types. Animals with some conservation status, either provincially or federally. Wetlands identified as locally significant by the Ministry of Natural Resources using evaluation procedures established by the province, as amended from time to time. The MOE monitors pollution and restoration trends in Ontario and uses that information to develop environmental laws, regulations, standards, policies, programs, and guidelines. The MOE works to provide cleaner air, land, and water for Ontarians. Measures taken to reduce adverse impacts on the environment. 12

13 Mitigative Measure Monitoring Monitoring Well Net Effects Action or program intended to offset known impacts to an existing natural resource such as a stream, wetland, or endangered species. Periodic or continuous surveillance or testing to determine the level of compliance with statutory requirements and/or pollutant levels in various media or in humans, plants, and animals. A monitoring well is a well drilled at a specific location on or off a hazardous waste site at which ground water can be sampled at selected depths and studied to determine the direction of ground water flow and the types and quantities of contaminants present in the ground water. The impacts, both positive and negative, of an alternative, which remain after avoidance / mitigation / compensation / enhancement measures have been applied. Night-time Defined as the hours from 22:00 to 07:00. Noise Level Non-hazardous Waste Nuisance Effect Odour Odour Unit Official Plan This is the same as sound level except that it is applied to unwanted sounds, general the sound level at a point of reception. Non-hazardous wastes includes all solid waste that does not meet the definition of hazardous waste and includes designated wastes such as asbestos waste. An effect of a project that is considered to be inconvenient or annoying (e.g., noise, traffic). An odour is deemed as a nuisance if it is detected and considered to be unpleasant. When odour levels are elevated and occur frequently, they can be construed as having an adverse effect. An odour unit is defined as the quantity of odourous substance that, when dispersed in 1 m 3 of odour free air, becomes just detectable by a normal human observer whose sensitivity to the odorant represents the mean of the population. The average odour detection threshold is 1 OU/m 3, although odours at this level are not necessarily a nuisance. Odour concentrations that may cause a complaint due to their ability to annoy typically range from 3 to 5 OU/m³. The objectionable level for odour is considered to be generally in the range of 3 to 5 OU/m³. These levels are more closely related to public complaints. An Official Plan is a statutory document adopted by a municipality, which contains the goals, objectives and policies established primarily to manage and direct physical change and the effects on the social, economic and natural environment of the municipality. An Official Plan consists of text and a series of corresponding maps. 13

Reg. 419/05) Open House Operational Flexibility Organic Overburden Perimeter Berm Point-of-Impingement (POI) POLLUTE Model Post Closure Potential Effect Ontario Regulation 232/98 under the Canadian Environmental Protection Act sets out standards, procedures, and requirements for non-hazardous waste landfilling sites in Ontario. The Regulation applies to every non-hazardous waste landfilling site that comes into existence, or landfilling site that is altered, enlarged or extended, and is intended to have a total waste volume of more than 40,000 cubic metres and to accept only municipal waste for disposal. The Province of Ontario has a regulation under the Environmental Protection Act that deals with local air quality (O.Reg. 419/05). This regulation sets out standards for various contaminants and procedures for assessing and reporting whether or not a proposed emission source is expected to meet the standards or cause them to be exceeded. However, O.Reg. 419/05 does not apply to discharges of contaminants from motor vehicles.
