Works and Emergency Services:
Purpose:
This report is supplemental to the May 15, 1998 report on the implementation of a 100 percent biosolids beneficial
reuse program at the Main Treatment Plant (MTP) and responds to the various motions for further information as
requested by the Works and Utilities Committee at its meeting of May 20, 1998, when the report was considered.
The recommendations contained in this report supersede those of the previous report.
Funding Sources, Financial Implications and Impact Statement:
Approval of the recommendations of this report would require budgetary approval in 1998 for expenditure of
$15,000.00 to support public consultation, $400,000.00 for the retention of technical consultants, $50,000.00 for the
retention of a Project Manager, and up to $250,000.00 to reimburse proponents who develop comprehensive
proposals to support beneficial use of the biosolids from the Main Treatment Plant. Total 1998 expenditures would
thus be projected at up to $715,000.00. Total 1999 expenditures are estimated at up to $115,000.00.

Council Reference/Background/History:
At its meeting held on February 11, 1998, the Works and Utilities Committee recommended that incineration of
sewage sludge at the MTP be stopped no later than January 1, 1999. This recommendation was referred back to the
Committee by City Council. A report dated March 16, 1998, was submitted to the Works and Utilities Committee
meeting of March 25, 1998, by the Commissioner of Works and Emergency Services.
At its meeting of March 25, 1998, the Works and Utilities Committee deferred consideration of the Commissioner's
March 16, 1998 report and requested additional information on 12, 24 and 36-month plans for implementation of
100 percent beneficial reuse of biosolids.
A related report, dated May 15, 1998, was submitted to the Works and Utilities Committee meeting of May 20,
1998, by the Commissioner of Works and Emergency Services. The report was referred back to staff for revision
and additional information.
Comments and/or Discussion and/or Justification:
The Biosolids Multi-Stakeholder Committee (BMSC) will be established immediately to facilitate ongoing public
involvement in the ending of incineration at the Main Treatment Plant. Representatives from the neighbourhood
liaison committees from the Humber and Highland Creek Treatment Plants will be included so that the Biosolids
Multi-Stakeholder Committee will be able to address biosolids on a city-wide basis. The BMSC will have the
following membership:
(i)three City of Toronto Councillors (Chair of the Works and Utilities Committee and one Councillor from each of
the two wards containing the Main Treatment Plant, with the other two Ward Councillors serving as alternates);
(ii)six representatives from the Neighbourhood Liaison Committees (two each from Main Treatment Plant,
Humber Treatment Plant, and Highland Creek Treatment Plant Committees);
(iii)one environmental group representative;
(iv)one representative from the Safe Sewage Committee;
(v)one public health representative;
(vi)two representatives from local industry in the Port Area; and
(vii)one unionized staff representative from the Main Treatment Plant.
Each of the groups to be represented will nominate their own representatives. The group so formed will nominate
the remaining individuals as required. The BMSC will select its own Chair. The BMSC will need to be established
immediately so that they may provide input into the development of the criteria for evaluating the Requests for
Proposals.
The Technical Advisory Committee (TAC) will be established immediately to provide technical advice on all
aspects of the biosolids program. The role of the TAC is to provide outside technical advice as required, to review
and develop recommendations on all documents related to the notification, short-listing and selection of proponents
for beneficial reuse of biosolids from the treatment plants, with the following membership:
(i)Chair of the Works and Utilities Committee (Chair);
(ii)one representative from the Biosolids Multi-Stakeholder Committee;
(iii)General Manager of Water and Wastewater Services;
(iv)one university representative with expertise in a discipline related to biosolids;
(v)two representatives from municipalities which have successfully implemented a beneficial use program; and
(vi)one representative with expertise in biosolids regulations.
The TAC will need to be established immediately so that they may provide input into the development of the
Request for Proposals, the short-listing of the Expression of Interest submissions and the criteria for evaluating the
Requests for Proposals. The consultant will assist staff and the TAC in the preparation and evaluation of the RFPs.
The 36-month plan presented in the report of May 15, 1998, has been revised to allow for an initial Expression of
Interest for the construction of required facilities and the provision of biosolids beneficial reuse programs. This will
allow for the inclusion of technologies other than those presented in previous reports. The Expressions of Interest
will be evaluated in conjunction with the TAC and a short list of qualified companies will be invited to submit
proposals for design/build construction of facilities and/or provision of biosolids reuse programs. The proposals
will be evaluated based on criteria developed with input from the TAC and the BMSC.
(A copy of a preliminary timeline for the EOI and RFP process, is on file in the office of the City Clerk).
At the request of the Works and Utilities Committee, included in the minutes of its May 20, 1998 meeting, the
following information is provided.
Consumers Gas Assistance with Plant Heating Requirements:
As stated in the report of March 16, 1998, we received estimates from private contractors to provide mobile boilers
to provide steam generation. Consumers Gas has indicated that they would follow a similar procedure as they do
not supply industrial boilers or services directly. They would recommend one of their authorized dealers to perform
required work and then finance the purchase through the gas bill. City staff are also investigating the feasibility of a
co-generation project involving the MTP, Toronto Hydro, and local industry which would provide thermal energy
as well as electricity.
Results of Harbour Remediation & Transfer Inc. Pilot Testing:
The pilot testing and sampling at Harbour Remediation & Transfer (HR&T) has quantified the expected air flow
rates, concentrations of particular odorous compounds and typical odour concentrations. The testing has indicated
that a removal efficiency of greater than 99 percent is required and attainable through the use of a carefully selected
series of odour control equipment and some modifications to the HR&T facilities and process equipment. Work is
now proceeding on preliminary design to establish the required capital and operating costs. All of the biosolids sent
to HR&T for the pilot tests has been removed from the HR&T site in accordance with their Certificate of Approval.
A presentation will be made to the Committee by Zorix Consultants on the odour control project at its June 17,
1998 meeting.
MTP Solids Train Audit:
A solids train audit was initiated by our staff at the MTP in November 1996. The sludge audit's goal is to improve
operating performance and increase the effectiveness of the existing facilities. The audit has been proceeding
steadily and has already resulted in significant improvements in the performance of solids handling facilities at the
MTP. For example, digester hydraulic retention time has been increased from 8 days to over 12 days by changes in
process control. A more detailed report will be presented in 1999. The results and progress of the sludge audit will
also be reviewed by the TAC.
Additional work will begin in 1999 as a joint effort between the City of Toronto, the Ontario Ministry of the
Environment, and Environment Canada, focusing on digester optimization and the effects of operating parameters
on biosolids stabilization, and odours. The results of this report and the sludge audit will be used to help develop a
protocol for other sludge audits in Ontario and assist in the further development of sludge stabilization guidelines.
Conclusions:
In order to establish the 100 percent biosolids utilization at the MTP, it will be necessary to implement the
components recommended in this report, and for the Committee to provide the Commissioner with authority to:
-establish the Technical Advisory and Biosolids Multi-Stakeholder Committees as soon as possible;
-retain consultants to assist the department and the Technical Advisory Committee.;
-retain a biosolids project manager to work with the consultant to prepare necessary Expressions of Interest and
Request for Proposals; and
-prepare necessary EOI, short-list submission, and prepare and release RFPs for required facilities and biosolids
management programs.
Attaining a 100 percent biosolids beneficial use program within as short a time as possible will require that all of
the plan's components are tightly integrated. We will submit regular progress reports to the Works and Utilities
Committee, updating the status of the various activities.
Additional reports on the long range plans for the City's biosolids management will developed in concert with the
TAC and the BMSC, and recommendations will be brought to this Committee.
