The Ministry of the Environment (MOE) approved the EA to expand the Trail Waste Facility in June 2005. As well, the Trail Road Site is set to commence using the vertical expansion capacity as approved. As a result of a decision made by Waste Management of Canada to rebalance significant quantities of waste as of August 1, 2007 to the Trail Waste Facility (TWF), the City of Ottawa will look at options to best accommodate the increase in waste quantities at the Trail Waste Facility.
This report will:
This report will have no tax levy or solid waste rate implications since sufficient revenue and operating savings will be generated to offset capital costs and operating expenditures. The net budget impact of this report if approved is (19,000) for 2007 and (5,604,000) for 2008.
Trail Road Facility Landfill Expansion
Future Residential Development Impact on Trail Waste
Facility Expansion Sequence
The development sequence of the landfill, as envisioned in the Environmental Assessment was to continue to proceed higher on Stage 4, to the maximum height, then move to Stage 3, 2, 1 and then Stage 5. In 2005, Solid Waste Services staff participated in the Barrhaven South Community Development Plan that considered the development interests to the east of Highway 416. These proposed developments are in close proximity to the Trail Waste Facility. In considering the impacts of development close to the landfill boundaries, staff requested that the MOE Approvals Branch allow alteration of the landfill filling sequence to mitigate dust, odour and noise by staging landfill operations away from future development.
The request to change the landfilling sequence was approved by the MOE and allows operations to commence on Stage 1, proceeding to the west, toward Stages 2, 3, 4 and 5. Therefore, operations will be moving away from the Barrhaven Urban Community to better coordinate with future development.
As a result of the changes to the MOE filling sequence, an opportunity to install an interim barrier cap on Stage 3 and 4 was investigated. It was determined the cap will achieve significant cost savings for the City through the reduction in volume of leachate produced and is therefore being installed commencing this fall. Reduced leachate volumes significantly delay the requirement for an on-site leachate treatment system. In the interim, until on-site treatment is required, the significantly reduced leachate volumes will be discharged to a new short haul distance leachate disposal facility at the Hunt Club Snow disposal site.
The preferred landfill gas management system is
collected through horizontal perforated piping in the waste and converted to
electricity. Power Trail Inc.,
comprised of Energy Ottawa in partnership with Comcor Environmental Ltd. and
Integrated Gas Recovery Services commissioned the 5 MW generation facility in
January 2007. Capital funds are
available to extend the gas collection system as the approved landfilling
operations expand at the Trail site.
Compost Pad Relocation
The existing leaf and yard composting facility currently resides over top of the future Stage 5 landfill footprint. Staff has received approval to utilize a property on Barnsdale Road as the future leaf and yard composting facility.
The new site was cleared of vegetation in 2007 and will be accepting leaf and yard waste this fall. The preparation of the Stage 5 footprint includes removing approximately one million cubic meters of clean fill material.
It is projected that the requirement for this material as daily and intermediate landfill cover will be reduced through the use of alternative cover systems. Therefore, approximately 500,000 cubic metres of sand could be sold, generating $4 million in potential revenue.
A new small load facility is
currently under construction at the Trail site to better handle the increased
tonnage. The facility will ensure the
public has safe access to dispose of their waste by separating smaller vehicles
from larger commercial ones. Also, the
facility design allows for enhanced waste segregation supporting new waste
diversion opportunities.
Provincial environmental regulations require 15 centimetres of daily cover over the waste to prevent odours, vectors and fires. An additional 15 centimetres of interim cover is added to areas of the site that have not had active operations for 90 days.
Under the EA process to expand
the landfill site, it was determined that 1.6 million cubic meters of daily and
intermediate soil cover is required to properly cover the waste over the course
of the remaining landfill site life. Use
of clean soil as daily and intermediate landfill waste cover is not considered
desirable as this material has a relatively high monetary value. Currently, staff use approved daily cover
such as tarps, auto shredder residue, street sweepings and water main break
soils as alternatives to clean soil. In
addition, the City sources mildly impacted soil materials for use as
alternative daily cover to offset some of the site cover requirements when
these materials are available. To
maximize the air space and minimize the use of clean soils, staff proposes to
purchase a spray on alternative daily cover system and a tarp roller system.
Alternative Daily Cover Systems
Recently, new landfill cover technology has been developed that involves a spray on mixture of mineral/cellulose-based product. When water is added to the mixture it can be sprayed over most surfaces, creating a uniform encapsulating layer that meets the requirements of daily cover. These formulations, when properly applied in layers less than 1 centimetre thick, can replace the minimum requirement of 15 centimetres of cover soils. The Trail Waste Facility currently uses tarps to cover waste for short periods of time, and an additional tarp roller will be required due to the increased tonnages.
The spray on cover application machine and tarp roller is considered a fleet purchase. However, as this technology was recently developed this machine was not included in the 2007 Fleet Growth Report, nor identified in the 2007 Capital Budget. The capital cost for the purchase of the spray on cover equipment is estimated to be $85,000 with annual fleet operating costs of $15,000.
Spray on cover materials will cost approximately $5,000/month based on an average of 21 working days /month, for a total annual operating cost of $75,000. The capital cost of the tarp roller system is estimated to be $90,000, but there are no operating costs associated with the use of this system.
The greatest advantage to the City in switching to the use of alternative daily cover systems is that it saves valuable landfill volume air space. In order to comply with Provincial regulations the annual requirement for typical soil cover would occupy 47,400 cubic metres of air space. Assuming spray on cover and tarps can be applied nine months of the year, the total air space saved each year would be 31,597 cubic metres or space for an additional 30,996 tonnes of revenue generating garbage. This would extend landfill site life by several years as well as add an additional $2.25 million in annual revenue (based on a $75.00/tonne tipping fee).
The use of an alternative daily cover spray system will require an amendment to the Trail Waste Facility certificate of approval. The local office of the Ministry of Environment has been pre-consulted and is amenable to this amendment to the CofA.
A
number of new equipment purchases were identified through Fleet for 2007
including a larger waste compactor. It
is expected that the larger compactor will increase compaction efficiency by
approximately 20%, also contributing to the extension of the landfill site
life.
In preparation for the move from Stage 4 to the expansion of Stage 1 of the Trail Facility, a road was needed to access Stage 1. Through the Infrastructure Services Branch, a notice was placed in the Construction News requesting road building materials. These materials were secured from a private sector demolition project. The use of recycled stripped asphalt and construction debris allowed for cost avoidance in the building of the access road to Stage 1. In 2007, Solid Waste Services have saved $250,000 in material procurement costs, and generated an additional $160,000 in tipping fee revenue creating a $410,000 financial benefit for the City.
As part of the requirements for the expanded landfill operation, material for a clay barrier was sourced along the perimeter of Stages 1 and 2. This generated a tipping fee revenue of $160,000 for the City, rather than a cost.
Impact of Reduced Operations
at the Waste Management Landfill Site in Carp
Waste Management of Canada reduced operations effective August 1, 2007 and is diverting approximately 68,000 tonnes per year of City of Ottawa residential waste and 50,000 tonnes of industrial/commercial/institutional waste to Trail Road Landfill site for at least four years. The Trail Waste Facility previously disposed of less than 170,000 tonnes of waste per year. The additional 118,000 tonne increase will have a significant impact on the operation of the Trail Waste Facility. Staff recommend that the revenue generated by the increased tipping fees be used to purchase equipment and increase staffing levels to handle the increase in tonnage.
The 2007 Solid Waste Services Operating Budget and full-time equivalent (FTE) complement will need to be adjusted to incorporate the following increase in staffing levels:
1.5 Full Time Equivalent (FTE) Scale Attendant
3 FTE Labourers
1 FTE Minor Equipment Maintenance Person
2 FTE Heavy Equipment Operators
Existing 2007 Capital Budget Authority exists for the purchase of the following equipment:
1 - Spray-on-Cover System - $85,000
Additional Capital Budget funding of $2,865,000 M will be required in 2007 to purchase the following additional equipment to accommodate the increase in solid waste tonnages. The cost components are as follows:
1 - additional weigh scale and software package - $175,000
1 - 100,000 tonne waste compactor – $1,200,000
1 - D7 sized bulldozer - $900,000
1 - Tarp Roller Cover System - $90,000
1 - articulated dump truck - $500,000
As identified above, 2 FTE Heavy Equipment Operators will be required in 2007 once the new equipment is acquired and in operation.
Table 1 summarizes the proposed landfill expansion site life. These dates assume that waste received at the site may fluctuate in the next few years as waste disposal technologies are investigated, but will then stabilize as disposal options are implemented. City staff had projected the Trail Waste Facility would have a site life of 23 years. However, the acceptance of an additional 118,000 tonnes/year of waste for four years will affect the fill rate of the Trail Waste Facility as illustrated in Table 1. It is assumed that after the four-year period the increase in tonnage will be redirected away from the Trail Waste Facility.

CITY STRATEGIC DIRECTION
The recommendation in this report have been developed and presented with the following City Strategic Direction priority and objectives in mind:
Landfill
Retain its two-landfill sites in public ownership as strategic assets that benefit the community;
Continue to reserve landfill disposal capacity within the City for locally generated solid waste;
Recognize the value of conserving landfill capacity, and consider the export of residential waste where economics warrants.
Technologies
That the City monitor, test, evaluate and implement initiatives that leverage technology or environmental benefits, as appropriate.
Source Separated Organics
(SSO)
Endorsement of a target of 60% diversion for Ottawa residents to be
achieved by year-end 2008
Implementation of an Organics Collection Program within the next solid waste collection contracts
Staff solicit “Requests for Proposals” from the private sector for organics processing technology.
The utilization of the Carp Road landfill since 2001, to dispose of one third of the residential waste stream, allowed the city to secure landfill capacity for Ottawa generated waste. With limited Carp Landfill capacity remaining, this residential waste is now being directed to Trail Road.
In 2007 Council approved the export of some residential waste to the Lafleche Landfill in Moose Creek to provide additional capacity for Ottawa waste.
The department is continuing the review of new technologies to provide alternatives to landfill, such as the partnership with Plasco Energy Group for a demonstration gasification plant being constructed at Trail Road.
A Request for Proposals for SSO processing was issued and closed this summer, with a report scheduled on 25 September 2007 to the Planning and Environment Committee and on 2 October 2007 to CSEDC. .
ENVIRONMENTAL IMPLICATIONS
Careful management of the Trail Waste Facility will provide a long-term environmentally sound solid waste handling option for the City.
In addition, through the environmental assessment approval process staff put forward a strategy to mitigate dust, odour and noise by:
The Trail Waste Facility has a Public Liaison
Committee, which meets four times a year.
They have been consulted on operational changes and expansion related
issues. In addition, normal notices
were given through the publication of the Planning and Environment Committee
Agenda.
