ADVICE DOCUMENT
FOR THE PREPARATION OF
AN ENVIRONMENT ACT PROPOSAL AND
ENVIRONMENTAL ASSESSMENT FOR AN ALTERATION
TO THE CITY OF BRANDON'S
INDUSTRIAL WASTEWATER TREATMENT FACILITY
BACKGROUND:
This Advice Document has been prepared to provide guidance to the City of Brandon, the Proponent, in the preparation of an Environment Act Proposal for an alteration to their industrial wastewater treatment facility (I-WWTF) to be filed under The Environment Act concurrently with a proposed alteration to be filed by Maple Leaf Foods Inc. respecting the upgrading of the Maple Leaf Pork plant in Brandon from a 1-shift per day operation to a 2-shift per day operation, together with such modifications to the plant as may be necessary. Maple Leaf Foods have already been licenced for a 2-shift operation of the Maple Leaf Pork plant through Environment Act Licence No. 2311 S2R, however, their Licence restricts the operation of that plant to only 1-shift per day operation until the City of Brandon's I-WWTF has received an Environment Act operating licence authorizing the facility to accept the wastewater generated by a 2-shift operation of the Maple Leaf Pork plant.
The 2-shift per day operation of the Maple Leaf Pork plant and the expansion/upgrading of the I-WWTF will, if approved, necessitate revisions to (3) current Environment Act Licences:
In addition, Environment Act Licence No. 2506 issued to the City of Brandon for the land application of biosolids from the anaerobic basin of Brandon's I-WWTF may need to be reviewed in the context of the increased quantity of biosolids that will need to be applied to land versus the long-term sustainable availability of sufficient suitable private agricultural land that may be offered for this purpose by local land owners.
The existing City of Brandon's I-WWTF, its proposed alteration to accommodate the 2-shift per day operation of the Maple Leaf Pork plant, and the process wastewater pre-treatment facility owned and operated by Maple Leaf Foods Inc., will hereafter in this guidance document be referred to simply as "the proposed Development". The term "Proposal" will refer to the City of Brandon I-WWTF proposal to be filed concurrently under The Environment Act with the process wastewater pretreatment facility alteration to be filed by Maple Leaf Foods Inc.
All environmentally significant proposed Developments in Manitoba are regulated by The Environment Act (C.C.S.M. c. E125). Manitoba Regulation 164/88 under this Act sets out the types of Developments which are automatically subject to an assessment and licencing process prior to their construction, operation or alteration. The Proposal will be considered pursuant to Section 11 of the Act. A Clean Environment Commission hearing will be held.
An interdepartmental Technical Advisory Committee (TAC) has been established to provide advice and guidelines for the assessment of potential environmental effects and the preparation of an appropriate Environmental Assessment (EA) report, and to evaluate the final EA report prepared by the Proponent. This TAC consists of provincial department technical staff and Federal representation as a matter of protocol, by agreement between the Province of Manitoba and the Federal Government through "A Canada-Wide Accord on Environmental Harmonization" and its "Sub-agreement on Environmental Assessment", in order to facilitate a coordinated approach to the review of proposed projects where both the provincial and the federal jurisdictions have a legislated requirement or interest in the environmental assessment and review of such projects.
During the EA process and the preparation of the EA report, the Proponent is encouraged to work closely with the TAC assembled for the project. This committee can provide the proponent with any required interpretation of the advice document, and can provide on-going feedback to the Proponent concerning the content and methodology of the assessment. In this way, any problems or new issues that were not accounted for in the EA guidelines can be dealt with, and the Proponent will have the opportunity to fill in deficiencies as the assessment is proceeding rather than after it has been completed.
Persons preparing the EA shall have an appropriate combination of formal education, skills, experience and training to conduct a technically sound and rational EA.
The Proponent is also strongly encouraged to undertake a public consultation process with local and downstream citizens, First Nation bands and environmental interest groups, that may be affected or concerned by the proposed Development so as to: provide a clearer awareness and understanding of the proposed Development; to receive feedback on the environmental issues of particular importance to the potentially affected or concerned parties; and to respond, whenever possible, to questions from the public.
ENVIRONMENTAL ASSESSMENT GUIDELINES
The purpose of these EA Guidelines is to provide the Proponent with an outline for an EA Report that the Director requires to make a licencing decision. These guidelines are intended to address the broadest range of information. The items listed should be considered but not all may necessarily apply to the proposed Development.
In order to assess the impacts of the proposed Development, it is necessary to establish a current environmental baseline of the environmental conditions at the proposed site and in the receiving environment. Furthermore, in the case of this Proposal, the total cumulative effect, not just the incremental additional amount due to the 2-shift per day production implementation, will need to be examined.
Where upon the Proponent finds it difficult to compile some of the following requested information in a timely fashion, the Proponent should consult with the Chairperson of the TAC. The EA report produced as a result of the assessment process should clearly document that information which is lacking and the rationale for not being able to provide it in the EA report. Also, the EA report should outline the options and time frames whereby the lacking information can be collected, evaluated, interpreted and presented to the Department within a practical time frame following the licencing of the proposed Development. New information acquired after the proposed Development is licenced may be used to revise the prevailing Licence through the provisions of The Environment Act.
The EA report should include the following components:
(Note: Existing data and reports can be used to the extent available and appropriate)

- Emissions to the atmosphere, including:
- identification of all air emissions, including:
- identification of their sources by location and characterization of the chemical constituents of the air emission;
- pre-treatment and post-treatment emission rates, concentrations and other measurable levels of pollutants as to their gaseous, particulate, noise and odour characteristics (can be obtained from literature or from the operating data from other similar facilities, except that, if emission factors are used to determine the emission rates, these emission factors should be justified); and

- include such information as materials balances and water balances.
6. Environmental Impact Assessment
The intent of the environmental impact assessment is to identify any significant effect on the environment, and on the social, economic, environmental health and cultural conditions that influence the lives of people or a community in so far as they are caused by environmental effects attributed to the proposed Development. The required environmental impact assessment will involve the following steps:
- Identify all of the sources of both probable and certain impact (whether positive or negative) related to the proposed pollutant releases and activities, associated with the proposed Development.
- Identify the magnitude and duration of these impacts by describing them as major and minor impacts, direct and indirect impacts, short-term and long-term impacts, and the time frame in which these impacts will occur in the future. Estimations should be made of the effects to the receptors either directly or indirectly as a result of air emissions.
- Evaluate and interpret the potential impact of all of these sources for each "Impact Category" described below.
- Evaluate the worst case scenarios of the impacts and their probability of occurrence.
- Support assessment conclusions and statements with data or modeling information.
- Where computer models are utilized to predict the impacts from air emissions, an initial screening should be conducted as a first stage approach to estimate severe emission impacts. The appropriate model and modeling characteristics will depend on the site parameters. Discussion with Manitoba Conservation must take place to ensure the modeling output satisfies the intent of the environmental impact assessment. Depending on the outcome the initial screening, additional detailed modeling may be required.
Impact Categories
a) Environment
Usually referred to as the "natural" environment, this includes:
- surface and groundwater;
- fish and other aquatic organisms, including the habitats that support them;
- air;
- wildlife;
- vegetation both natural and agricultural;
- soils; and
- historic (heritage) resources.
The impacts on the environment should include human, flora and fauna impact of nuisance, annoyance and avoidance caused by the emissions or discharges.
The impacts on the water quality in the Assiniboine River should be assessed relative to the standards, objectives and guidelines contained in the "Technical Draft, Manitoba Water Quality Standards, Objectives, and Guidelines" (MWQOG), dated February 1, 2001, along with the recommended implementation policies including those for design flows, mixing zones and acute lethality, whereby:
- the principle variables of concern are bacteria, protozoa, biochemical oxygen demand, dissolved oxygen, toxic forms of nitrogen such as ammonia and nitrate-nitrite, and plant nutrients including all forms of nitrogen and phosphorus, without excluding any other additional important variables that may be identified;
- suspended solids and 5-day biochemical oxygen demand are each normally regulated at not greater than 30 milligrams per litre;
- the information generated from the Assiniboine River Monitoring Study conducted by the Proponent over the past several years, and the river water quality model developed over the same period, should be used by the Proponent to:
- derive daily effluent loading limits for ammonia as would be applicable and specific to each month of the year whereby no more than a 75% allocation of the calculated total assimilative capacity of the river, at a transect immediately upstream of the effluent outfall from the proposed Development, is utilized (this may necessitate the modeling of impacts from major ammonia inputs upstream of the proposed Development relative to the ambient water quality upstream of the City of Brandon whereby each major ammonia discharger would be entitled up to the same % allocation of the total assimilative capacity available at their respective outfall to the Assiniboine River, excepting those outfalls already restricted by fixed caps); and
- adequately demonstrate that the effluent discharges resulting from the Proposal will not cause exceedances with respect to each applicable criterion laid out in the MWQOG;
- the Proponent should submit a summary report and interpretation of the findings of the nutrient studies conducted on the Assiniboine River over the past several years as part of the Assiniboine River Monitoring Study; and
- no further net increase in total nitrogen and total phosphorus due to the proposed Development will occur to the Assiniboine River unless it can be clearly shown from the river studies and the water quality model that no effect will be observed on algal growth, while bearing in mind that upon the completion of Manitobas Nutrient Management Strategy, it may be necessary to further reduce concentrations of nitrogen and phosphorus releases to the river.
Impacts upon the receiving waterway due to the release of any identified pollutants should also be assessed by addressing the cumulative effects of pollutant releases upon the ecology and downstream uses of the receiving waterway.
The impacts on air quality due to emissions identified in Section 5 should include:
- the impact of the proposed Development's peak daily, monthly average, and project life average projections on the existing ambient air quality beyond the site of the proposed Development for all pollutant releases compared to Manitoba's "Ambient Air Criteria" and "Guidelines for Sound Pollution", and where applicable, to flora and fauna tolerance levels;
- the impact of the atmospheric greenhouse gas emissions from the proposed Development, expressed in terms of annual mass and annual percentage of the total estimated greenhouse gas emissions generated in Manitoba (as provided by Manitoba Conservation); and
- the broader impact of the whole spectrum of air emissions relative to acid rain, ozone depletion, vegetation, soil residuals, local nuisance conditions, cumulative effects, etc.
b) Land Use
This involves assessing the impact of location and operation of the proposed Development relative to the local land use planning program.
c) Natural Resource Uses
This involves assessing the impact of the proposed Development on the current use(s) and identified future use(s) of water and land based resources, including but not limited to:
- surrounding lands, especially those having designated uses (i.e. agricultural, residential, commercial, parks, etc.);
- existing natural resources such as groundwater used by any authorized residents, institutions, or industries sharing the same aquifer;
- existing surface water resources used for irrigation water by downstream authorized users of the Assiniboine River up to and including the City of Portage la Prairie;
- existing surface water resources used directly or indirectly as a drinking water source by communities and First Nations located downstream along the Assiniboine River up to and including the City of Portage la Prairie; and
- existing natural resources such as fisheries, wildlife, forests and other habitat.
d) Traffic Pattern Changes
This involves assessing the impact of the proposed Development upon the comfort, well being and livelihood of the residents, institutions and commercial operations located along the main transportation and haulage roads proposed to serve the proposed Development, as well as any added potential risk to safety due to any increased traffic brought about by operating the proposed Development.
e) Environmental Health
This involves assessing the health risks of pollutants released through the construction and operation of the proposed Development on the environmental health of neighbouring human receptors.
f) Aboriginal People
This involves assessing any effect on the current use of lands and resources for traditional purposes by aboriginal people.
g) Socio-economic
This involves assessing any social and economic effects resulting from the environmental impacts identified through the preceding assessment sub-sections 6(a) to 6(f), and would not be restricted to a 10 kilometre distance from the site of the proposed Development.
7. Mitigative Measures
Describe the measures and/or technologies that will be implemented to prevent, mitigate or eliminate the impacts identified in the course of the environmental impact assessment. Discuss the expected effectiveness of the mitigative measures. Anticipated residual impacts which will remain after all reasonable mitigation measures have been undertaken need to be identified, and their significance assessed. Mitigative measures may include changes in design, chemical reagents or other capital measures, as well as non-capital measures such as changes in process or layout of the process train, improved recycling, re-scheduling and other practices.
Where potential impacts have been identified and no mitigation is contemplated, an explanation is required.
Identify alternative technologies which could mitigate the impacts, together with the reasons for which they were or are rejected.
Describe the proposed environmental management practices to be employed to prevent or mitigate adverse implications from the environmental impacts on environmental health.
Describe, as well, further mitigation that could be used if, once the proposed Development is operational, residual impacts are found to be higher than predicted and are found to be unacceptable.
8. Contingency Planning
For acute situations, describe contingency planning (and where possible, actual plans) to be applied in the event of a non-routine occurrence which could adversely affect the environment or public health or safety. Include consideration of the following, where applicable:
- malfunction of process equipment;
- malfunction of emission control equipment or wastewater treatment or pretreatment facilities;
- fire;
- accidental spills or releases of dangerous goods or hazardous wastes;
- transportation accidents;
- surface runoff from an extreme (1 in 100 yr.) rainfall event; and
- level of risk and potential consequences of pollutant transport by floodwater, and if applicable, measures to mitigate the associated impacts.
For chronic situations such as:
- an extended disruption of the I-WWTF;
- an extended disruption of the hog slaughterhouse and processing plant and/or the wastewater pretreatment facilities; or
- an extended disruption of services by the contracted hauler or disposer of the biosolids from the anaerobic cell(s) of the I-WWTF;
describe the contingency planning for disposing of wastewaters and biosolids from the I-WWTF.
In the event that, upon the completion of Manitobas Nutrient Management Strategy, it may be necessary to further reduce concentrations of nitrogen and phosphorus to the Assiniboine River, the proponent should outline a strategy whereby, if required, the nutrient contributions from the proposed Development to the Assiniboine River could be reduced.
9. Proposed Environmental Monitoring
Describe the proposed environmental monitoring facilities, the parameters proposed to be measured, the rationale for selecting these parameters, and the frequency of measurement proposed for obtaining statistically valid monitoring data on the following, where applicable:
- ambient environmental quality:
- air quality (particulate, gaseous, volatile organics, odour and noise respecting air emissions);
- surface receiving water (upstream and downstream); and
- groundwater (up gradient and down gradient);
- point source particulate and gaseous air emissions;
- liquid influent to the I-WWTF;
- liquid effluent from the I-WWTF;
- groundwater subject to potential impact;
- any other point source surface liquid discharges off the site of the proposed Development; and
- plant site property surface runoff.
Provide drawings showing all the proposed sampling locations, along with associated facilities, for the collection of wastewater, groundwater, ambient water quality, point source air emission and ambient air samples.
Outline the proposed technique and equipment to be used for collecting the samples, and for measuring the volumetric rates of discharge of stack emissions and major wastewater streams, where applicable.
10. Decommissioning
Elaborate on the life expectancy of the proposed Development and the projected plans concerning the eventual decommissioning of the proposed Development, including all waste storage and treatment facilities.
11. Principles and Guidelines of Sustainable Development
Address each of the ten principles and six fundamental guidelines of Sustainable Development, listed in the publication of the Manitoba Round Table on Environment & Economy titled "Towards A Sustainable Development Strategy For Manitobans", by providing a summary paragraph on each principle and guideline, describing how the Proposal endeavors to satisfy the respective principle and guideline.
12. Public Participation
Describe the program of public awareness and public input which has been undertaken in respect of the proposed Development, and include the results of that public participation. If such a program has not been undertaken, this should be stated together with an explanation for why not.
13. Technical References
All assessment conclusions should be backed up by credible technical or scientific information. Previous studies and reports may be utilized if they still have relevance. Properly referenced information could include:
- technical studies of similar facilities and processes which are operating elsewhere;
- original studies performed by qualified engineers, scientists and other professionals commissioned by the proponent specific to the proposed facilities;
- facility design documents as prepared by qualified engineers; and/or
- peer reviewed scientific reports and papers on topics relevant to the facility.
Deficiencies in the technical or scientific evidence should be clearly delineated. All null impact conclusions must be supported by credible analysis and documentation.
14. Report Format
The EA report should include an executive summary and should be written with a minimum of technical jargon. Where highly technical portions are essential to the document, definitions or explanations should be included. A glossary of terms should also be provided.
The information presented in the document should maximize the use of maps, charts, diagrams, and photographs to present the information. Maps and diagrams should preferably be presented at a common scale wherever possible to allow direct overlay for ease of reference. Specifically, maps indicating zones of impact to land and water use areas and habitat areas should be of a common scale.
