Tlicho Community Government of Gamètì, NT Sewage and Solid Waste Sites

1 INTRODUCTION

In 2003, Dillon Consulting Limited (Dillon) was attained by Public Works and Services, Government of Northwest Territories to design and develop the sewage treatment and solid waste facilities for the community of Gamètì. As part of the design services, Dillon will provide assistance with the water license application process for the Tlicho Community Government of Gamètì by providing a background report that will accompany the application form. The background report gives an overview of the design and operation for both the sewage treatment and solid waste facilities which is based on previous information from the design stage. This report includes a combination of background information and design data for the community’s municipal infrastructure sewage and solid waste collection, treatment, and management.

2 BACKGROUND

2.1 Community Description

Situated in the North Slave Region of the Northwest Territories between the Great Slave and Great Bear Lakes, the community of Gamètì is located at 64°07' north latitude and 117°21' west longitude, about 177 km northwest of Yellowknife by air. Access to Gamètì is available year around by aircraft and by a winter ice road between January and March. Figure 1 below shows the location of Gamètì with respect to the other communities in the region.

Figure 1: Map of Northwest Territories Source: http://nwt-tno.inac-ainc.gc.ca/mp_e.htm

Dillon Consulting Limited Page 1 Tlicho Community Government of Gamètì, NT Sewage and Solid Waste Sites

Gamètì is located in a traditional hunting area of the Dogrib and Sahtu Dene peoples. For a long time, the area surrounding the community was used as temporary camp. However, during the 1970s, people began to settle in the area when main infrastructure such as an airstrip, school and store were built. Figure 2 below shows an aerial photo of the community.

Figure 2: Aerial Photo of the Community of Gamètì, NT Source: http://www.maca.gov.nt.ca/governments/resimages/north_slave/rae_lakes.jpg

According to the Legislative Assembly of the Northwest Territories, Gamètì means “Gamè’s place” which refers to the surname of the first elder to settle in the area but according to the Prince of Wales Northern Heritage Centre, the word Gamètì means “rabbit-net lake” where 'Gamè' means 'rabbit' and 'ti' means 'lake' and/or water. The community of Gamètì was formally known as Rae Lakes until August 4th, 2005, when it became a Tli Cho community and a part of the Tlicho Government.

3.2 Water Treatment Facility

There are no infrastructural changes to the existing water supply system in Gamètì, NT pertaining to this application; the community wishes to include the current water treatment facility in this water license application. Appendix B contains reports completed by the Government of the Northwest Territories, Public Works and Services which describe the water supply and treatment facility in entirety. Table 3 outlines some of the potential environmental impacts of the existing system.

Table 3: Environmental Impacts IMPACT MITIGATION

• Municipal water supply is required. Draw Down Effect in Rae Lake • Recharge of lake off-sets water use by water supply system.

• An intake screen is in place, to reduce environmental impact of water intake. Drawing Water into Piping System • Screen prevents uptake of large material from lake, including fish and plant life.

• Operators properly handle chemicals according to MSAS. Chlorine Spills • Seal containers when not in use. • Proper storage of containers as per MSDS. Aerial Emissions from Vehicles • Use of trucks is required for delivering water to community.

• Trucks and pumps will be serviced regularly, to ensure they are in proper working order. Fuel Sills from Tucks, Pumps • Spill Contingency Plan.

3.3 Sewage Treatment Facility

3.3.1 System Overview

The sewage treatment facility, situated approximately 1.6 km northeast from the airport, includes the following components: ƒ Sewage collection system. ƒ Access road to disposal site. ƒ Landfill area consisting of designated areas for different types of generated waste.

Sewage treatment facility consists of a constructed lagoon cell and a small wetland area for the treatment of the municipal wastewater. The site is accessible by an access road and truck turnaround area. Annual sewage generation of the community is estimated to be 10,460 cubic meters (m3). The sewage is treated using an annual lagoon cell where the material is broken down by biological activity during the months of May, June, July and August. Discharge occurs once a year, generally in September prior to freeze up, over a period of 10 days.

3.3.2 Waste Collection and Disposal

Presently, 47 buildings are on pump out systems while the remaining 36 buildings have sewage bag collection. Those buildings that have pump out systems sewage is collected via vacuum trucks and delivered to the sewage lagoon by vacuum trucks on a daily basis. Honey bags are collected twice a

Dillon Consulting Limited Page 6 Tlicho Community Government of Gamètì, NT Sewage and Solid Waste Sites week along with the domestic solid waste. Sewage is disposed of in the lagoon cell using the discharge chute.

3.3.3 Access Road and Truck Pad

Access road to the sites is approximately 4 km in length. The truck pad, 14 m in diameter, is located prior to the lagoon cell, where the trucks can turn around and discharge the sewage. Road alignment and truck pad details are illustrated in Figures 101-108.

3.3.4 Discharge System

Truck discharge area consists of discharge flume located at the end of the truck turnaround area, closest to the lagoon cell. Figure 108 shows the details of the discharge system of the lagoon cell.

3.3.5 Lagoon Cell Design

Lagoon cell was designed to hold and treat the sewage generated by the community for one year. Cell has a rectilinear shape with dimensions of 107 m by 107 m, measured from the tops of outside berms. This shape helps to promote plug flow conditions and to minimize mixing of raw effluent with treated effluent. The cell design also takes into account sludge generation over the lifetime of the facility. Figure 108 shows the site layout of the lagoon cell.

3.3.6 Decanting System

As mentioned previously above, decanting occurs once a year usually in the fall prior to freeze up. Decanting system consists of a pipe and pump system that is located at the opposite end of the discharge system and truck and turnaround pad. Details of the decanting system are shown in Figure 108.

3.4 Solid Waste Facility

3.4.1 System Overview

The site for the solid waste facility will be located approximately 1.6 km northeast from the airport. In relation to the sewage treatment facility, the solid waste site is situated on the south side of the existing access road. The system includes the following components: ƒ Solid waste collection system. ƒ Access road to disposal site. ƒ Landfill area consisting of designated areas for different types of generated waste.

Total volume of generated solid waste for the community is about 31,500 m3 in the design year. Due to the topography of the area, solid waste is deposited using the depression/area method. Compaction of the waste is not performed due to the fact that the equipment required for the task is not available in the community.

Dillon Consulting Limited Page 7 Tlicho Community Government of Gamètì, NT Sewage and Solid Waste Sites

3.4.2 Waste Collection and Disposal

Domestic solid waste is collected twice each week, on the same days as bagged sewage, by a two person crew using a 1-tonne Ford F-350 truck.

3.4.3 Access Road

The same access road used to reach the sewage lagoon will also be used to access the solid waste facility. Alignment and details of the access road are shown in Figures 101-107.

3.4.4 Landfill Design

Areas have been mapped out as to where the cells, the bulk materials, hazardous waste materials, and honey bags are to be placed for final disposal. Layout of the solid waste facility is shown in Figure 108.

3.4.4.1 Domestic Waste Area

The solid waste system consists of the four cells, each having a life capacity volume of about 7,900 m3. It is estimated that each cell will accommodate for 5 years worth of generated solid waste for the community, servicing the community for the next 20 years.

The domestic waste area consists of a natural deep depression in the landscape. Solid waste is dumped at the top of the slope of the depression and then spread down into the cell. To improve odors and discourage scavenging, a 100 mm of cover should occasionally be placed on the waste pile. In the spring or fall or when the waste is 3 m wide, the cell will be covered with 300 mm of suitable granular material. A mix of dry sand, peak and clay is the preferred material as it prevents seepage and promotes growth of surface vegetation. New waste is then dumped and spread down the new slope and the process is repeated until the depression is full.

Garbage is to be deposited to a height of 2 m or through the entire depth of the depression so that a level surface is created to allow an additional layer of cells to be placed on top using the area method, extending the landfill’s life. Generally, a ratio of 1:4 is used as a standard estimation for the amount of cover material to compacted material. Although waste will not be compacted in this facility, adequate amounts of cover material will still be required to provide intermediate fill as well as final cover between cells as there is no burning of waste permitted at the site.

3.4.4.2 Hazardous Waste

An area, located within the solid waste facility, is designated for the disposal of hazardous waste. Bins are supplied to store hazardous wastes that are generated from the health centre until they can be transferred out of the community for proper disposal.

Dillon Consulting Limited Page 8 Tlicho Community Government of Gamètì, NT Sewage and Solid Waste Sites

3.4.4.3 Bulk Waste

Bulk items and materials for disposal are still to be placed of at the existing site with the exception of certain household items such as fridges, stoves, dishwashers, clothes washers, dryers and hot water heaters. These items will be collected at the new solid waste site at its own designated bulk area. Those items that contain hazardous materials like refrigerant, mercury, and polychlorinated biphenyls (PCBs) will be set aside until a certified technician has removed the hazardous waste/material from the item.

3.4.4.4 Honey Bags

An area within the landfill is designated for the disposal of honey bags. This area consists of a pit where the trucks can off load and store the honey bags as they are collected.

3.4.4.5 Recyclable Materials

There is no recycling established within the community so any items and/or materials that can be recycled are disposed of with the other waste materials at the main landfill disposal site.

3.4.5 Drainage System

The drainage system for the landfill involves a raised berm around the perimeter of the disposal area in addition to ditches and culverts installed to redirect surface water from entering the site and creating more runoff. This will help prevent any leachate or contaminated wastewater to leave the disposal site.

3.4.6 Fencing

Problems have arisen with birds and wildlife entering the disposal area. To ensure that no wildlife can enter the site area, watch-man fencing is installed on the top of the perimeter berm, surrounding the entire area of the solid waste facility. A lockable gate is also be installed to prevent Details of the fencing are shown in Figure 109.

4 OPERATION AND MAINTENANCE PLANNING

Operation and Maintenance (O&M) Manuals will be established for both the sewage and solid waste facilities. These manuals will provide guidelines and procedures to follow during all operations and maintenance of the facilities.

4.1 Sewage Treatment Facility

Monitoring and maintenance of the sewage treatment facility shall include the following procedures: ƒ Berms will be monitored to ensure that there are no leaks. ƒ Discharge flume and truck pad will be monitored, especially during the winter months, to ensure that wastewater does not freeze and build up on the truck pad and discharge flume. Regular

Dillon Consulting Limited Page 9 Tlicho Community Government of Gamètì, NT Sewage and Solid Waste Sites

removal of frozen wastewater is required to reduce the amount of piles accumulated over the season.

4.2 Solid Waste Facility

For the solid waste facility, the following are O&M procedures that will be implemented for the system: ƒ Drainage system will be monitored to help ensure that leachate will not enter any part of the environment outside the disposal area. ƒ The honey bag disposal area will be covered frequently with either soil or lime during the times of warm weather to prevent the breeding of flies. ƒ Surface water monitoring program will be implemented to track changes of any leaking from the disposal site. A minimum of three (3) sampling points - upstream and downstream of the disposal site as well as the entering of the receiving body - will be required. However, other additional and/or specific requirements may be stated in the land and water license. ƒ There have been issues with a potential increase in bird and wildlife activity near the airport area due to the fact that the landfill is in close proximity to the airstrip. Regular covering of the solid waste with granular material is required to minimize the amount of birds and wildlife entering the disposal area. More frequent coverage should occur in the spring, summer and fall as there is a higher increase in bird activity. The airport authorities should be contacted to check if operations of the landfill are causing additional bird and wildlife activities for the area.

The plan has been prepared to ensure quick access to all the information required in responding to a spill.

1.5 Community Environmental Policy

The Tlicho Community Government of Gamètì has no formal environmental policy; however, Gamèti is committed to operating in an environmentally sensitive manner, and complying with requirements of the Wek'èezhìi Land and Water Board.

1.6 Project Description

This spill contingency plan will be used by the community, for activities associated with community operations. These include:

• Operation of the water treatment plant • Operation of the sewage disposal site • Operation of the solid waste facility • Storage and handling of hazardous materials

1.7 Site Description

Situated in the North Slave Region of the Northwest Territories between the Great Slave and Great Bear Lakes, the community of Gamètì is located at 64°07' north latitude and 117°21' west longitude, about 177 km northwest of Yellowknife by air. Access to Gamètì is available year around by aircraft and by a winter ice road between January and March.

Gamètì is located in a traditional hunting area of the Tlicho and Sahtu Dene peoples. For a long time, the area surrounding the community was used as temporary camp; however, during the 1970s, people began to settle in the area when main infrastructure such as an airstrip, school and store were built. Figure 1 below shows an aerial photo of the community.

Note: Worst case scenario in brackets.

3.2 Potential Environmental Impacts of Spill

Generally, for the hazardous materials discussed below, environmental impacts are lower during the winter, as snow is a natural sorbent ad ice forms a barrier liming or eliminating soil or water contamination. Spills can be recovered more readily recovered when identified and reported.

Gasoline: Environmental Impacts: • Harmful to wildlife and aquatic life • Not readily biodegradable • Has potential to bioaccumulate in environment • Volatilizes easily • Runoff into water bodies must be avoided

Dillon Consulting Limited Page 10 Wek'èezhìi Land and Water Board Gamèti Spill Contingency Plan

Worst Case Scenario: All fuel drums open simultaneously and contents pour onto ground and surrounding environment.

Diesel: Environmental Impacts: • Harmful to wildlife and aquatic life • Not readily biodegradable • Has potential to bioaccumulate in environment • Burns slowly (more readily contained than volatile fuels) • Runoff into water bodies must be avoided

Worst Case Scenario: All fuel drums open simultaneously and contents pour onto ground and surrounding environment.

Waste Oil and Miscellaneous Oils and Grease: Environmental Impacts: • Harmful to wildlife and aquatic life • Not readily biodegradable • Has potential to bioaccumulate in environment • Runoff into water bodies must be avoided

Worst Case Scenario: All storage drums open simultaneously and contents pour onto ground and surrounding environment.

Sewage: Environmental Impacts: • Human health hazard, and unsightly appearance • High nutrient concentrations could negatively impact water bodies and runoff into water bodies must be avoided

Worst Case Scenario: Full sewage truck releases all of its contents onto ground and surrounding environment.

Liquid Chlorine: Environmental/Health Impacts: • Harmful if inhaled, corrosive, causes eye and skin burns, causes digestive and respiratory tract burns • Run-off into water bodies must be avoided

Worst Case Scenario: All pails open simultaneously and contents pour onto ground and surrounding environment.

3.3 Procedures

3.3.1 Procedures for Initial Actions

The following list of actions should be followed by the first person on the scene:

• Ensure safety of all personnel • Identify the product spilled • Assess the hazards and risks to persons in the vicinity of the spill • If possible, without further assistance, control the danger to human life • If it is safe to do so, and if possible, stop the spill (i.e. shut off pump, replace cap, tip drum upward, etc.) • Gather information on the status of the situation, including: o Estimated size of spill o Estimated migration route • Contact Municipal Supervisor, as per flowchart in Figure 3.

3.3.2 Spill Reporting Procedures

Spills should be reported immediately to the Municipal Supervisor, who will notify the SAO. Together they will determine if the spill is to be reported to the NWT 24-Hour Spill Line at 867-920-8130.

Copies of the Spill Report form are available in each spill kit and at the back of this manual. The form will be filled out by the Public Works Foreman (or designate), and faxed or emailed to the NWT Spill Line. Contact information is as follows:

NWT 24-Hour Spill Line Phone: (867) 920-8130 Fax: (867) 873-6924 Email: [email protected]

3.3.3 Procedures for Containing and Controlling Spill General procedures noted below will be used to contain and control all spills. Specific procedures for spills on land, water, snow and ice follow.

• First anticipate what will be affected by the spill. • Assess direction and speed of spill, and any factors that could affect these. • Determine best location for containing spill.

Dillon Consulting Limited Page 12 Wek'èezhìi Land and Water Board Gamèti Spill Contingency Plan

Spills on Land: Dykes and trenches can be constructed to contain spills on land. Soil surrounding the spill area can be dug out, and piled up, to create a barrier for the spill. A plastic tarp can be placed at the base of the dyke, so that the pooled material can be removed with sorbent materials. Conversely, trenches can be excavated to permafrost, which will provide a natural containment of the spill. Once the material is contained, it can be pumped out, or removed by using sorbent materials. If the spill is moving very slowly, such structures may not be necessary and the material can be removed before migrating away from the spill location.

Spills on Water: Spills on water are considered the most serious types of spills, as there is often no containment of the spilled material and water quality and aquatic life are negatively impacted. Booms and weirs can be installed to contain the spill. Booms are designed to float, and are made of absorbent material to soak up the spilled fuel. They are deployed from the shore or a boat, to create a circle around the spill. Weirs are installed across a stream, to prevent further migration. Plywood or other materials found onsite can be used. Barriers made of fence or netting can be used as well, with sorbent material placed at the base of the barrier. Once contained, the fuel can be removed by absorbent materials, pumped out or allowed to volatilize.

Spills on Snow: Snow acts as a natural sorbent for spilled fuel. Impacted snow is easily visible, and can be shoveled into empty drums or barrels for proper disposal. If the spill is migrating down a hill, a snow dyke can be constructed to contain the spill. A plastic tarp can be placed at the base of the dyke, where spilled fuel is expected to pool. The collected fuel and impacted snow ban be removed with absorbent materials, pumped out, or shoveled into barrels for disposal.

Spills on Ice Ice is considered impermeable to fuel, so these spills are generally easy to clean up. Small spills can be cleaned up by placing absorbent materials on top of the ice. Impacted snow and slush can then be removed by shovels, and placed in barrels for disposal. For larger spills, dykes of snow and trenches can be constructed to contain the spill. Pooled fuel can then be removed by adsorbent materials or pumped out. Impacted snow and slush can be shoveled into barrels for disposal.

Worst Case Scenarios: Worst case scenarios include a dyke or trench overflowing and a large spill on water that cannot be contained with materials available in the community. In the first case, a trench or collection pit could be constructed downstream to collect the fuel. In the second case, an emergency response team would need to be called, with appropriate equipment to deal with the spill.

Dillon Consulting Limited Page 13 Wek'èezhìi Land and Water Board Gamèti Spill Contingency Plan

3.3.4 Procedures for Transferring, Storing and Managing Spill Related Wastes

Spills are generally cleaned up starting at the outer limit of the spill, and working towards the point of the spill. Sorbent materials and hand tools such as cans and shovels are used for smaller spills. Larger spills can be contained with the use of a pump and/or heavy equipment.

Spill wastes include used absorbent materials and containers of impacted water and snow. Sorbent materials should be placed in plastic bags for proper disposal. The containers of impacted water and snow should be sealed and stored until disposal at an approved facility can be arranged.

Following a spill, all used materials need to be properly washed and/or replaced.

3.3.5 Procedures for Restoring Affected Areas

Once a spill has been contained, community personnel will consult with regulatory personnel assigned to the file to determine the level of clean-up required. Regulatory personnel may request that a site specific study be conducted, to ensure appropriate clean-up levels are met.

Attention: Mark Cliffe-Phillips, Regulatory Specialist

Re: Abandonment and Restoration Plan

Dear Mr. Cliffe-Phillips:

Please find attached a copy of the Abandonment and Restoration Plan – Plan Outline as a part of the water license application package. The attached plan is the initial framework document for the final closure plan. The community is currently seeking a licence for new sewage and solid waste facilities. At present they have started road work improvements to access the land at the proposed sites. These road works are part of a broader community plan to access this area.

The project schedule outlined in this document is to have the roads completed by 2009, and the new sewage and solid waste sites constructed (subject to licensing) in 2010. Once the new sites are operational, and existing site will be closed, likely in 2011.

We suggest it would be appropriate to have the full development of the closure pan to be part of the new licence terms and conditions, and that the completion of that closure plan to be in place 6 months prior to the commissioning of the new sites.

We trust you find the attached report to your satisfaction.

Yours truly,

Dillon Consulting Limited

Abandonment and Reclamation Plan Sewage and Solid Waste Facilities

1 INTRODUCTION

1.1 Purpose

The purpose of the Abandonment and Reclamation (A&R) Plan is to assist with the closure of the existing site and help with the monitoring of the site after its closure.

1.2 Schedule

The proposed scheduling for the construction of the new sites and the decommissioning of the existing sites is shown in Table 1 below.

Table 1: Schedule

Proposed Item Completion Date Completion of New Facilities October 2010 Start of Decommissioning of Previous Facilities November 2010 Start of A&R Program for Previous Site April 2011

2 LOCATION

The existing sewage and solid waste facilities are located approximately 1.3 km east of the community, 250 m from the shoreline of Rae Lake, on the south side of the peninsula. Originally built in 1991, the site sits in a natural depression and covers an approximate area of 27,000 m2. Figure 1 shows the location of the existing site in relation to the community. All figures are contained in the appendix and are from the CECL report.

Both the sewage and domestic solid waste facilities occupy the same partially-fenced enclosure at this site. The enclosure contains areas for the sewage pit, bagged toilet waste trench, domestic waste trench and bulky waste area. Refer to the site layout (Figure 1) shown in Appendix A.

2.1 Sewage

Liquid sewage is disposed of in a pit that has approximate dimensions of 20 m x 50 m x 2 m. There is no seasonal discharge from the pit; sewage seeps naturally into the ground. The pit is located at the north end of the site, directly adjacent to the bagged toilet waste trench. Refer to Photo #2 in Appendix A.

2.2 Solid Waste

The waste facility consists of the following areas: ƒ Honeybag Disposal Area ƒ Refuse Solid Waste Area

Page 1 Abandonment and Reclamation Plan Sewage and Solid Waste Facilities

ƒ Bulky Waste Area

2.2.1 Honeybag Disposal Area

Bagged sewage or honeybags are disposed of in the bagged sewage pit that is located at the north end of the site. The bagged sewage pit is essential a trench with dimensions of 27 m x 8 m x 1 m. When the trench is full, the untreated honey bags are buried. Refer to Photo #3 in Appendix A.

2.2.2 Refuse Solid Waste Area

There has been approximately one solid waste trench per year of operation. The dimensions of the trenches are approximately 15 m x 30 m x 2 m. Each spring, a new trench is constructed and garbage is collected and disposed of in the trench. Following the next trench construction, previous trench is covered with granular material. However, periodic covering is not practiced. Waste is sometimes burned in the trench using waste oils collected as ignition. The current trenches are located in the north- east corner of the site. Refer to Photo #4 in Appendix A.

2.2.3 Bulky Waste Disposal Area

Bulky wastes on site include car bodies, appliances and construction waste. The bulky waste disposal area consists of two piles that are located at the west end of the site. Refer to Photos #5 and #6 in Appendix A.

3 CLOSURE

The existing landfill should be closed in an environmentally responsible manner in order to eliminate scavenging by wildlife and birds and to mitigate against health and safety risks to the community residents. Wek’èezhìi Land and Water Board requires notification of the site’s pending closure. Finalizing the closure plan will occur at least six months prior to closure of the landfill.

3.1 Future Land Use

Future land use of the existing site should be limited to the types of use that conform to the revision use patterns. It is recommended that the site be used for either one of the following activities: ƒ Related storage area; ƒ Bulk waste storage area; ƒ Waste transfer station; ƒ Passive recreation (ball field); and/or, ƒ Open area or green space.

3.2 Infrastructure and Material Removal

3.2.1 General

The gate and fencing should be removed and reused if possible at the new site, or in other community locations. If not, then these items should be land-filled at the new solid waste facility or sent to an applicable disposal area as part of the closure plan.

Page 2 Abandonment and Reclamation Plan Sewage and Solid Waste Facilities

3.2.2 Sewage

Remaining sewage will either be pumped out of the pit (treated before being released into the environment) or remain in the pit where the sewage will be allowed to dry before any cover material is laid. The sludge accumulated at the bottom of the pit will be removed, dried and sent to the landfill and used as covering material in the new land fill operation, or as part of the closure plan.

3.2.3 Solid Waste

The site will be cleaned up of litter so that all loose waste is adequately covered. This will reduce the likelihood of birds flying back and forth between the old and new landfill sites and keep wind blown waste out of the community.

All hazardous waste such as waste oil, batteries, etc. should be identified and removed to an appropriate storage facility within the community. Disposal of the hazardous waste is not permitted in the NWT. The community will be required to contact a hazardous waste disposal company to remove these wastes periodically.

3.3 Grading and Capping

Once the facility has been cleared of all of items, the site should be capped with 600 mm of clay cover material if available. If clay is not available, fine sandy material should be used. The clay or fine sand material layer should be covered with 200 mm of organic material to allow vegetation to take hold. This final cover should be graded to encourage drainage of precipitation away from the landfill to discourage creation of leachate, and seeded to stabilize the soil and to prevent erosion.

3.4 Survey

A final survey of the site should be performed to map out the exact area of the facility. The mapping will show areas of the site facilities, potential contamination, disturbed areas, borrow material, and monitoring wells.

3.5 Registration

On all land title documents, the site should be identified and registered as a former Sewage Treatment and Solid Waste Management Facility.

3.6 Signs

A sign should be posted at the site location to notify residents that the site has been closed as a sewage lagoon and landfill. The sign should also indicate that the locations of the new facilities (where the sewage and solid waste can now be placed).

Page 3 Abandonment and Reclamation Plan Sewage and Solid Waste Facilities

4 POST CLOSURE

Periodic inspection and monitoring of the site following its closure is necessary to prevent un intended environmental impacts. Regular testing and reporting is necessary until the site no longer releases contaminants or until the regulators are satisfied that there is no long term environmental impact likely to occur.

4.1 Inspections

Inspections of the site will be implemented through a post closure inspection checklist. The checklist will be prepared and sent to the Wek’èezhìi Land and Water Board to be placed on file. It should include the following items: ƒ Timeframe of inspection; ƒ Frequency of inspection; ƒ Items to be inspected; and, ƒ Regulatory compliance requirements (SNP monitoring locations and test parameters).

4.2 Monitoring

Monitoring program of the site shall consist of the following tasks: ƒ Cover material should be monitored for settling and regarded or filled in as required to prevent pooling; ƒ Vegetation should be monitored to ensure sufficient growth; ƒ Drainage pathways should be kept clear of obstructions; ƒ Water as well as leachate draining from the site should be tested for contaminants; ƒ Wildlife levels within the area should be monitored; and, ƒ Reporting of results.

4.3 Regulatory Requirements

The applicable Land and Water Board will be monitoring and require updated reports on the monitoring of the site.
