                     MUNICIPAL CLASS ENVIRONMENTAL ASSESSMENT
                     FOR THE REHABILITATION OF CRANBROOK ROAD BRIDGE

                             NOTICE OF COMPLETION
THE PROJECT:
The Municipality of Huron East is planning to carry out repairs to Cranbrook Road Bridge, which
spans the Middle Maitland River immediately west of the community of Cranbrook (as shown on the
accompanying key plan). Recent engineering inspections of the structure have identified
deterioration with several bridge components. The rehabilitation project would involve the
replacement or repair of the identified bridge elements, including replacement of the existing
concrete railings with solid concrete barrier walls.
At this time, it is anticipated that the bridge rehabilitation project would be completed during the 2010
construction season. The affected road section of Cranbrook Road would be closed during the
construction period and traffic would be diverted around the project site onto adjacent roads.

THE ENVIRONMENTAL SCREENING PROCESS:
The planning for this project is following the environmental screening process set out for Schedule B
activities under the Municipal Class Environmental Assessment. The screening process has been
completed. There were no negative impacts identified with the proposed road project that could not
be mitigated. Subject to any comments received as a result of this Notice and the receipt of
necessary approvals, the Municipality of Huron East intends to proceed with this project.

                          FOR THE REHABILITATION OF
                           CRANBROOK ROAD BRIDGE

                          ENVIRONMENTAL SCREENING REPORT


1.0     INTRODUCTION

1.1     Purpose of the Report
The Municipality of Huron East initiated a Class Environmental Assessment process in
September 2009 to identify the best strategy for resolving deficiencies identified with Cranbrook
Road Bridge. This structure spans the Middle Maitland River along Cranbrook Road
approximately 300 m west of Perrie Line. The process followed the procedures set out in the
Municipal Class Environmental Assessment (Class EA) document, dated October 2000. B. M.
Ross and Associates Limited (BMROSS) was engaged to conduct the Class EA process on
behalf of the proponent.
The purpose of this report is to document the Class EA planning and design process followed for
this project. The report includes the following major components:

•       An overview of the general project area.
•       A summary of the deficiencies associated with the structure.
•       A description of the alternative solutions considered to resolve the identified problems.
•       A synopsis of the decision-making process conducted to select a preferred alternative.
•       A detailed description of the preferred alternative.

1.2     Municipal Class Environmental Assessment (Class EA) Process

Municipalities must adhere to the Environmental Assessment Act of Ontario (EA Act) when
completing road, sewer or waterworks activities. The Act allows the use of Class Environmental
Assessments for most municipal projects. The Municipal Class Environmental Assessment is an
approved planning document which describes the process that proponents must follow in order to
meet the requirements of the EA Act. The Class EA approach allows for the evaluation of
alternatives to a project, and alternative methods of carrying out a project, and identifies potential
environmental impacts. The process also involves mandatory requirements for public input.

The Class EA process is a method of evaluating projects which have the following important
characteristics in common:
•       They are recurring.
•       They are usually similar in nature.
•       They are usually limited in scale.
•       They have a predictable range of environmental effects.
•       They are responsive to mitigating measures.
If a Class EA planning process is followed, a proponent does not have to apply for formal
approval under the EA Act. The development of the Class EA process for this project has
followed the procedures set out in the Class EA document. Figure 1.1 presents a graphical
outline of the procedures.
The Class EA planning process is divided into these five phases:

•       Phase 1 - Problem identification.
•       Phase 2 - Evaluation of alternative solutions to the defined problems and selection of a
        preferred solution.
•       Phase 3 - Identification and evaluation of alternative design concepts in selection of a
        preferred design concept.
•       Phase 4 - Preparation and submission of an Environmental Study Report (ESR) for public
        and government agency review.
•       Phase 5 - Implementation of the preferred alternative and monitoring of any impacts.

Throughout the Class EA process, proponents are responsible for having regard for these
principles of environmental planning:

$       Consultation with affected parties throughout the process.
$       Examination of a reasonable range of alternatives.
$       Consideration of effects on all aspects of the environment.
$       Application of a systematic methodology for evaluating alternatives.
$       Clear documentation of the process to permit traceability of decision-making.

1.3     Classification of Project Schedules

Projects are classified to different project schedules according to the potential complexity and the
degree of environmental impacts that could be associated with the project. There are three levels
of schedules:

$       Schedule A – Projects that are approved with no need to follow the Class EA process.
$       Schedule B – Projects that are approved following the completion of a screening process
        that incorporates Phases 1 and 2 of the Class EA process, as a minimum.
$       Schedule C – Projects that are approved subject to following the full Class EA process.

The Class EA process is self-regulatory and municipalities are expected to identify the
appropriate level of environmental assessment based upon the project they are considering.

1.4     Mechanism to Request a Higher Level of Environmental Assessment

Under the terms of the Class EA document, the requirement to prepare an individual
environmental assessment for approval is waived. However, if it is found that a project going
through the Class EA process has associated with it significant environmental impacts, a
person/party may request that the proponent voluntarily elevate the project to a higher level of
environmental assessment. If the proponent declines, or if it is believed that the concerns are not
properly dealt with, any individual or organization has the right to request that the Minister of the
Environment make an order for the project to comply with Part II of the Environmental
Assessment Act which addresses individual environmental assessments. This request must be
submitted to the Minister within 30 days of the publication of the Notice of Completion of the
Class EA process.

2.0     CLASS EA FRAMEWORK

2.1     General Approach

The Municipality initiated a formal Class EA process in September 2009 to define and evaluate
options for resolving deficiencies identified with Cranbrook Road Bridge (as outlined in section
2.4 of this report). It was identified at the outset of the Class EA process that the proposed
project may include components which would categorize the work as a Schedule B activity (e.g.,
significant repairs to a bridge in excess of 40 years old which could alter the appearance of the
structure). For this reason, the assessment followed the environmental screening process
prescribed for Schedule B projects under the Class EA document. The Schedule B screening
process incorporates these primary components:

i.      Background Review
ii.     Problem/ Opportunity Definition
iii.    Identification of Practical Solutions
iv.     Evaluation of Alternatives
v.      Selection of Preferred Alternative and Implementation

Figure 2.1 illustrates the general tasks associated with the screening process. The following
sections of this report document the findings for each stage of the assessment.

2.2     Background Review

A background review was carried out to obtain a general characterization of the project area and
to identify factors that could influence the selection of alternative solutions to the defined
problem.

The background review for this Class EA process incorporated these activities:

$       Assembly of information on the existing infrastructure and the environmental setting.
$       Review of deficiencies at the bridge site.
$       Preliminary assessment of the identified deficiencies and potential remediation.

A desktop analysis of the project setting was completed as part of the background review
process. The following represent the key sources of information for this analysis:

$       BMROSS. Ontario Structure Inspection Manual (OSIM) report.
$       County of Huron. Mapping services
$       Municipality of Huron East. Files and discussions with staff.
$       Ministry of Natural Resources. Natural Heritage Information Centre website.
$       Maitland Valley Conservation Authority. Discussions with staff.

2.3     Environmental Setting

(a)     Bridge Site

The Cranbrook Road Bridge site is located along Cranbrook Road, approximately 300 west of
the community of Cranbrook (as illustrated on Figure 2.2). The structure, which was constructed
in 1961, is surrounded predominately by farmland and forested areas. A farmstead and a rural
residence are also situated in relative proximity to the structure. Designated municipal structure
G12 Cranbrook Road Bridge is a two-span rigid frame/vertical leg structure situated on Lot 10,
Concession 11 (former Township of Grey). The bridge has a total deck length of approximately
35.6 m and an overall width of 8.37 m. Each bridge span is approximately 16.8 m in length. The
existing structure also has a minimal vertical clearance of 4.4 m from the normal water level and
an east-west orientation with a 31 degree skew.

Cranbrook Road extends in a southeast-northwest orientation approximately 28.5 km between
Road 173 (West Perth) and County of Huron Road No. 4. The roadway serves as a local road
connecting rural properties to nearby urban settlements (e.g., Brussels, Wingham, Blyth) and
major transportation routes in the area (e.g., Provincial Highway No. 23, Huron Road 4).

The main channel of Middle Maitland River meanders approximately 45 km in a northerly
direction from headwaters approximately 10 km east of the bridge to its confluence with the
Little Maitland River immediately south of Wingham. The Middle Maitland River maintains a
permanent baseflow, given the large drainage area contributing to the watercourse. The overall
slope of land along the channel is westerly over a gradual elevation change from approximately
360 m to 320 m (Geodetic Survey of Canada). The land elevation near the bridge is
approximately 350 m. At the bridge site, the floodway is characterized as a broad, shallow
valley incorporating riparian vegetation which appears to be common to the area (e.g., shrubs,
grasses and sedges, deciduous trees).

Figure 2.2 illustrates the approximate location of the structure and includes photographs of the
bridge site.

(b)   Summary of Natural Features

i.    Physiography and Soils

Table 2.1 summarizes the general physiographic features and soils evident in the vicinity of the
subject property.

                          Physiographic Features and Soil Types

            Feature                                   General Characteristics
          Physiography         •       Located in the Stratford Till Plain physiographic region.
                               •       The Stratford Till Plain is a broad clay plain of
                                       approximately 3,550 km2, which incorporates several
                                       terminal moraines. The moraines are closely spaced in
                                       the southwestern portion of the region.
               Soils           •       Soils in the study area are classified as Burford Loam and
                                       Harriston Loam; both series of the Grey-Brown Podzolic
                                       soil group. Burford Loam is characterized as well sorted
                                       gravely outwash. Harriston Loam is characterized as
                                       medium textured till. Both loam series exhibit good
                                       drainage characteristics.
                               •       Soils within the Middle Maitland River corridor are
                                       classified as Bottomland (part of the Azonal Alluvial
                                       Great Soil Group). This series is comprised of alluvial
                                       soils that exhibit variable drainage characteristics.

ii.     Sensitive Natural Features in the Vicinity of the Project Site

1.      Species of Conservation Interest (Species at Risk)

The Ministry of Natural Resources (MNR) conducted a search of the study area to identify the
possible occurrence of species at risk on, or near the project site. Accordingly to correspondence
dated, November 5, 2009, there are no ‘known’ occurrences for species-at-risk or provincially
rare species identified within the study area. However, there are known occurrences for Wavy-
rayed Lampmussel, upstream of the bridge and suitable habitat for the species in the vicinity of
the bridge.

2.      Natural Areas of Conservation Interest

The MNR Natural Heritage Information Centre (NHIC) database was consulted to verify the
current status of significant features within the study area. The NHIC database compiles,
maintains and distributes information on natural species, plant communities and species of
conservation concern in Ontario. Information is stored in a spatial database, permitting
geographic and juridictional-based inquiries of current conservation data.

Cranbrook Road Bridge Rehabilitation


Utilizing a jurisdictional natural areas search of the Cranbrook Road Bridge area, two natural
areas of conservation interest were identified in the Cranbrook area; the Central Grey Complex
Grey North Complex and the Trowbridge Complex. Both wetland complexes are designated as
Non-Provincially significant. Neither feature appears to be sitauted in the immediate vicinty of
the bridge site.

3.      Breeding Bird Habitat

The most recent Ontario Breeding Birding Atlas (2001-2005) designates the study area within
the geographic survey area entitled Square 17MH83 of Region 6 (Huron-Perth). A total of 34
birds, including species such as the Red-winged Blackbird, Savannah Sparrow, European
Starling and American Robin, have confirmed breeding status in this survey region. An
additional 49 species were categorized with probable or possible breeding status. The survey
area extends over 100 km2 and includes key habitat for the identified species, such as forests in
all stages of growth, wetlands and riverine areas. The project area represents a relatively small
portion of this region (~1,500 m2) and includes limited habitat opportunities, as the bridge site
forms part of an active road transportation route and is largely devoid of vegetation.

2.4     Bridge Assessment

Recent engineering inspections have identified several problems with the structural condition of
the bridge and the associated approach roads. Performance deficiencies associated with bridge
components are identified within the 2007 Ontario Structure Inspection Manual (OSIM) report
prepared by B.M. Ross & Associates (included in Appendix A to this report). Recent site
assessments of the bridge have also confirmed the problems detailed in the OSIM report.

The following are the primary structural deficiencies and safety concerns associated with the
existing crossing:

Identified Deficiencies:

$       Concrete bridge deck exhibits localized delaminated areas
$       Deck drains are undersized and corroded.
$       Concrete curbs exhibit deterioration.
$       Railings are deteriorated and do not conform to current bridge standards.
$       Guardrails are not provided along approach roads.
$       The bridge deck is exposed concrete and is not waterproofed and paved.

BMROSS, in consultation with the representatives of the Municipality of Huron East, conducted
a preliminary review of the nature and scope of the problems associated with the structure. From
this assessment it was determined that given the extent and significance of the identified
deficiencies, the bridge should undergo major repairs.

2.5     Problem Definition

Based upon a review of the deficiencies identified during the July 2003 bridge inspection, the
following problem statement has been developed for this Class EA:

        Key components of the Cranbrook Road Bridge exhibit advanced deterioration
        which, if not remediated, may have an adverse impact on the safe condition of the
        structure and may reduce the service life of the bridge.

In order to resolve the defined problem, the proponent has investigated a limited number of
practical alternatives including the rehabilitation of the bridge. The assessment followed the
planning and design process set out for Schedule B activities. Schedule B projects are approved
subject to a screening process which incorporates Phases 1 and 2 of the Class EA process (i.e.,
Problem Identification, Evaluation of Alternative Solutions). The purpose of the screening
process is to identify potential environmental impacts related to the identified alternative
solutions and to plan for appropriate mitigation of any identified impacts.

The deficiency defined in this section represents the problem statement for Phase 1 of this
Class EA.

2.6     Identification of Alternative Solutions
(a)     Scoping Exercise
Phase 2 of the Class EA process involves the identification and evaluation of alternative
solutions to address the defined problem(s). In this regard, Section A.2.3 of the Class EA
document prescribes that all reasonable and feasible solutions to the defined problem should be
identified, described and evaluated.
For this project, a scoping exercise was conducted to identify practical solutions to the defined
problems (given the nature of the defined problems and the environmental setting of the project
area). The exercise was carried out at the outset of the Class EA process and incorporated
information gathered from preliminary engineering investigations and an initial review of the
environmental setting.

Three potential options were explored during this review process:
$       Bridge Replacement.
$       Bridge Rehabilitation.
$       Do Nothing.

The following were among the general criteria considered to establish a practical set of
alternative solutions:
$       Disruption to Natural Features and Ecosystems.
$       Cultural and Heritage Preservation.
$       Land Use Conflicts.

$       Technical Complexity.
$       Economic Impacts.
$       Property Access.
$       Aesthetic Impacts.

Appendix B summarizes the findings of the alternatives scoping exercise and identifies the key
rationale for selecting specific alternative solutions for further consideration. In review, the
options to repair the bridge and do nothing were considered suitable for further analysis. The
bridge replacement option was determined to be unnecessary, as the service life of the structure
can be extended significantly through rehabilitation (i.e., the overall integrity of the structure
does not warrant consideration of bridge replacement at this time).

(b)     Alternative Solutions
Based upon the findings of the scoping exercise, the following alternative solutions were
identified for this Class EA:

Alternative 1 - Rehabilitate the Existing Structure. This option would involve a series of
major repairs to the existing bridge which, when completed, would remediate the deficiencies
identified by recent engineering inspections. The project would also involve work would
constitutes an aesthetic modification to the structure; replacement of the existing concrete
railings with new concrete barrier walls.

Alternative 2 - Do Nothing. This option proposes that no improvements or changes be made to
address the identified problem. During the Class EA planning and design process, this
alternative may be implemented at any time prior to the commencement of construction. A
decision to “Do Nothing” would typically be made when the costs of all other alternatives, both
financial and environmental, significantly outweigh the benefits.

3.0     EVALUATION OF ALTERNATIVES

3.1     General Process

The second component of Phase 2 of the Class EA process, being the evaluation of the defined
alternatives, is conducted by examining the technical, economic, and environmental
considerations associated with implementing any alternative. Mitigation measures that could
lessen environmental impacts are also defined. A preferred solution or solutions is then selected.

Several activities were incorporated into this assessment process, including a land use analysis, a
site inspection, a review of expert technical opinion and consultation with affected stakeholders,
municipal staff and regulatory agencies.

3.2     Assessment Methodology

(a)     Evaluation Method and Procedures

The evaluation of alternatives process was carried out using a comparative assessment
methodology designed to predict the nature and magnitude of environmental impacts resulting
from each defined option and to assess the relative merits of the alternative solutions. The
evaluation method involves these principal tasks:

•       Identification of existing environmental conditions (baseline conditions, inventories).
•       Assessment of existing land use activities, infrastructure, natural features and socio-
        economic characteristics (i.e., environmental scoping).
•       Review of proposed alternatives and related works.
•       Determination of the level of complexity required to complete the impact assessment.
•       Identification of environmental components and sub-components that may be affected by
        the defined alternatives (i.e., define evaluation criteria).
•       Prediction of environmental impacts (positive, negative) resulting from the construction
        and operation of the defined options.
•       Identification and evaluation of measures to mitigate adverse effects.
•       Prioritization of evaluation criteria, as required (i.e., weigh environmental components
        based on preference).
•       Selection of a preferred alternative following a comparative analysis of the relative merits
        of each option.

(b)     Level of Complexity

Section A.2.1.1 of the Class EA document prescribes that the level of complexity required to
assess alternatives is predicated on several factors, including the predicted environmental effects,
public and agency input and technical considerations. In this regard, the level of detail
inventoried during the Class EA process should reflect the potential severity of the anticipated
impacts.

At the outset of this Class EA, general impact screening criteria were reviewed to predict the
potential impacts from each of the defined alternative solutions at each bridge site. The Impact
Screening Checklist presented in Appendix B provides a summary of this review. In general,
these conclusions were drawn from the screening process:

•       The implementation of Alternatives 1 and 2 could impact upon environmental features.
•       The works associated with Alternatives 1 and 2 are relatively limited in scale and the
        impacts would be predominately construction-related (i.e., short duration).
•       Specialized studies (e.g., biological investigations) were not warranted to assess the
        identified impacts.
•       A low level of environmental assessment is required to evaluate the potential impacts of
        the alternative solutions.

Given these findings, information inventoried for this Class EA was gathered from the following
sources:

•       Existing policy guidelines and regulations.
•       Comments received through public consultation.
•       Input from review agencies and stakeholders.
•       Technical evaluations and expertise.

(c)     Public Consultation Program

Public consultation is an integral component of the Class EA process. Public consultation allows
for an exchange of information, which assists the proponent in making informed decisions during
the evaluation of alternative solutions.

The Ministry of the Environment (MOE) has established protocols for the design of Class EA
public consultation programs in order to facilitate effective, two-way communication during the
process. In this respect, the Ministry prescribes that to achieve meaningful participation, Class
EA consultation plans should adhere to these key principles:

•       Initiate consultation activities early in the process to promote dialogue and information
        sharing.
•       Ensure project information is disseminated adequately and effectively to affected
        property owners, stakeholders, review agencies and Aboriginal Communities (where
        appropriate).
•       Create multiple opportunities to engage interested parties and to solicit input.
•       Present the assessment process and the project in an open and transparent manner.
•       Establish a systematic method to record, review and consider input received.
•       Promptly acknowledge, and attempt to address, concerns raised.
•       Clearly document input received through consultation.
•       Identify outstanding concerns at the conclusion of the process.

At the outset of this Class EA process, a consultation program was developed that was
considered to be appropriate for the local environmental context and suitable for the nature of the
problem and the scale of the proposed alternatives. The specific elements of the program are as
follows:

•       Circulate a Notice of Commencement to the general public and affected property owners.
•       Distribute background information to government review agencies.
•       Compile and review comments received.
•       Acknowledge and respond to comments received via an appropriate method.
•       Arrange a public meeting to present project information and to solicit input, if needed to
        address concerns from stakeholders and the general public.
•       Circulate a Notice of Completion to interested parties and review agencies.
•       Prepare a Screening Report documenting the findings of the screening process as of the
        Notice of Completion stage. Make the report available for public review.
•       Acknowledge and respond to comments via an appropriate method.

•       Document input received and outstanding concerns within the Screening Report.
•       Attempt to address any outstanding issues.

Appendix B includes a brief synopsis of the rationale for adopting the above-noted consultation
plan.

3.3     Identification of Environmental Components and Sub-Components

(a)     Environmental Features

Section 2.6 (b) of this report listed the alternative solutions that were identified to resolve the
identified deficiencies. As part of the evaluation process, it is necessary to assess what effect
each option may have on the environment and what measures can be taken to mitigate the
identified impacts. The two main purposes of this exercise are to:

$       Minimize or avoid adverse environmental effects associated with a project.
$       Incorporate environmental factors into the decision-making process.

By definition, the EA Act generally separates the “environment” into five general elements:

$       Natural environment.
$       Social environment.
$       Cultural environment.
$       Economic environment.
$       Technical environment.

The identified environmental elements can be further subdivided into specific components and
sub-components, which have the potential to be adversely affected by the construction and/or
operation of the alternative solutions. For this Class EA, the identification of environmental
components and sub-components followed a review of background technical information and the
general environmental settings.

Table 3.1 summarizes the environmental features considered of relevance to this Class EA.

The environmental effects of each project alternative on the identified environmental features are
generally determined through an assessment of the following impact predictors (i.e., impact
criteria):
$       Direction (nil, positive, negative).
$       Nature (direct, indirect, cumulative).
$       Magnitude (level of effect, loss of function).
$       Location/ Extent (where effect occurs, number/ volume affected).
$       Scale (localized or regional effects).
$       Timing (seasonality of effects, immediate or delayed impacts).
$       Duration (period of impact).
$       Frequency (intermittent or continuous).
$       Reversibility (extent of recovery, recovery time).
$       Ecological context (characteristics of population affected, implications for future
        generations).
$       Socio-economic and cultural context (characteristics of affected community, implications
        for recovery).
For the purposes of this Class EA, criteria have been developed to predict the magnitude of
environmental effects resulting from the implementation of a proposed alternative. Table 3.2
summarizes the impact criteria.

    Level of Effect                                  General Criteria
                       Implementation of the project could threaten sustainability of feature and
         High          should be considered a management concern. Additional remediation,
                       monitoring and research may be required to reduce impact potential.
                       Implementation of the project could result in a resource decline below
      Moderate         baseline, but impact levels should stabilize following project completion
                       and into the foreseeable future. Additional management actions may be
                       required for mitigation purposes.
                       Implementation of the project could have a limited impact upon the
         Low           resource during the lifespan of the project. Research, monitoring and/or
                       recovery initiatives may be required for mitigation purposes.
                       Implementation of the project could impact upon the resource during the
     Minimal/ Nil      construction phase of the project but would have a negligible impact on the
                       resource during the operational phase.

Given these criteria, the significance of adverse effects is predicated on these considerations:
$        Impacts from a proposed alternative assessed as having a Moderate or High level of
         effect on a given feature would be considered significant.
$        Impacts from a proposed alternative assessed as having a Minimal/ Nil to Low level of
         effect on a given feature would not be considered significant.

3.4      Preliminary Assessment of Alternatives

(a)      Overview of Alternatives

A preliminary engineering analysis was conducted to determine the works required to implement
each of the identified project alternatives. Table 3.3 summarizes the findings of that assessment.

                        curbs and concrete railings.
                      - Install new steel guardrails along the approach roads.
 Alternative 2        - No additional works planned.

(c)     Environmental Effects Analysis

The potential interactions between the identified alternatives and environmental features (Table
3.1) were examined as part of the evaluation of alternatives phase. The purpose of this analysis
was to determine, in relative terms, the environmental effects of constructing and operating each

3.5     Preliminary Identification of a Preferred Solution

As an outcome of the preliminary assessment of alternatives summarized in Tables 3.4 and 3.5,
the proponent indicated a preference for implementing Alternative 1, Rehabilitate the Existing
Structure.

The following are the key attributes associated with this option which justified its preliminary
selection as the preferred servicing plan:

$       Resolves concerns relating to the deterioration of bridge components.
$       Improves traffic safety with the construction of a concrete barrier walls and the provision
        of guiderails along the approach roads.
$       Represents the most economical and practical option from an engineering perspective.
$       Involves no in-stream construction activities.

4.0     EVALUATION OF THE PRELIMINARY PREFERRED ALTERNATIVE

4.1     Framework of Analysis

Following selection of Alternative 1 as the preliminary preferred alternative, a study framework
was developed to further evaluate the potential impacts of implementing this servicing plan.
The purpose of this review was to assess the environmental interactions resulting from the
construction and operation of the project, and to determine if the identified interactions would
generate potential environmental impacts. Issues relating to the decommissioning of the
proposed works were not part of the scope of this assessment (the Class EA document requires
that proponents conduct separate environmental assessments for the decommissioning of works
considered Schedule B or C activities).

The assessment of the preferred alternative incorporated these activities:

$       Assessment of the construction and operational requirements of the proposed works.
$       Examination of the project implementation plan.
$       Consultation with the public, stakeholder groups and government agencies.
$       Prediction of the environmental interactions between the proposed works and the
        identified environmental components.
$       Identification of specific environmental features that may be impacted, in a significant
        adverse manner, by the proposed works.
$       Evaluation of the potential impacts of the project on the specific environmental features,
        including residual effects following mitigation.

The following section of the report summarizes the findings of the evaluation process.

4.2     General Project Scope

(a)     Construction Phase

i.      General Construction Sequence

The construction plan for this project generally includes the following general tasks:

$       Provide temporary construction signage at major intersections.
$       Mobilize to the site.
$       Implement the traffic control plan (including all necessary signs, barricades and
        signalization).
$       Complete site layout, including service locates.
$       Install temporary shoring.
$       Remove existing concrete curbs and railings.
$       Remove and replace deck drains.
$       Construct new concrete barrier walls with handrails.
$       Complete patch repairs and waterproofing of bridge deck.
$       Complete asphalt paving of deck surface and approach roads.
$       Install new steel guide rails for the approach roads.
$       Carry out standard site restoration activities.
$       Complete all required documentation and reporting on the works.
$       Conduct of any required remediation (e.g., concrete crack sealing, surface sealing).

ii.     Construction Mitigation

Construction-related activities associated with project implementation have the potential to
impact upon existing environmental features, the general public and construction workers. The
Contractor will therefore be responsible for carrying out these activities in accordance with
industry safety standards and all applicable legislation. Mitigation measures will also be
incorporated into the construction specifications to ensure that operations are conducted in a
manner which limits detrimental effects to the environment.

Table 4.1 outlines a series of mitigation measures that are typically incorporated into
construction specifications. For this project, contract specifications may need to be modified
depending upon the nature of the construction activity and any additional requirements of the
regulatory agencies.

4.4     Impact Assessment and Mitigation

(a)     Environmental Interactions

An assessment was conducted to identify and evaluate the environmental interactions which
could arise from project implementation. The assessment examined the potential impacts of
constructing and operating the proposed works on the defined environmental sub-components.
Table 4.3 summarizes the findings of the interactions assessment.

    (b)     Assessment of Interactions
    i.      Potential Adverse Impacts
    Based upon the findings of the general impact assessment (Tables 3.4 and 3.5) and the
    environmental interactions analysis (Table 4.3), the project has the potential to adversely impact
    upon a limited number of specific environmental features. They are as follows:

    •       Traffic Movement.
    •       Stream Ecology.

    The potential impacts to each identified feature are described in this section of the report and
    measures to mitigate the impacts are also presented. The selection of mitigation measures
    incorporated an assessment of mitigation requirements and an evaluation of alternative forms of
    mitigation. This assessment was based on the consideration of three broad approaches to
    mitigation; avoidance, minimization of adverse effects and compensation.

Cranbrook Road Bridge Rehabilitation




ii.     Discussion of Impacts

1.      Traffic Movement

As discussed, it is proposed that Cranbrook Road will be closed at the bridge site for the duration
of the construction period (approximately six weeks). The road closure would occur
immediately prior to the contractor mobilization to the site and traffic would be diverted onto
adjacent local roads. Appropriate signage would be provided prior to the road closure and
throughout the construction period.

The road closure proposed for this project will disrupt local traffic patterns throughout the
construction period. The overall impact of the plan, however, is expected minor in nature,
considering the limited traffic volume evident at the bridge site and the availability of suitable
alternate routes in the vicinity of the crossing.

2.      Stream Ecology

Construction activities associated with the bridge repairs could pose a minor risk to the ecology
of the project area, given the proximity of construction activities to the stream channel. In order
to address these concerns, a series of common protective measures will be incorporated into the
construction plans to help mitigate any identified impacts, including the provision of temporary
silt control measures (generally summarized in Table 4.1). However, it is anticipated that the
project will not require extensive mitigation as the construction plan does not incorporate in-
stream activities.

iii.    Residual Environmental Effects

The prediction of residual effects involved an impact analysis of the planned works on the
specific environmental features following the application of mitigation. The determination of
residual effects involved the evaluation of the potential negative impacts of the project with
respect to factors such as magnitude, duration, reversibility, frequency and geographic extent.

Taking the proposed works and the planned mitigation measures into consideration,
implementation of the project is not expected to have a significant adverse effect upon the
identified environmental features. In this regard, the anticipated residual environmental effect of
this project would be considered Minimal/ Low in magnitude based upon the impact criteria
presented in Table 3.2.

5.0     CONCLUSIONS AND PROJECT IMPLEMENTATION

5.1     Conclusions

Based upon the findings of the environmental impact evaluation, no potential impacts were
identified with Alternative 1 that could not be adequately mitigated. In this regard,
implementation of the proposed project appears to be appropriate for the study area and should
Municipality of Huron East
Class EA Environmental Screening Report                                                      Page 31
Cranbrook Road Bridge Rehabilitation


not result in adverse environmental effects provided the defined mitigation measures are
implemented. The merits of this option were also seen to substantially outweigh those identified
for the other alternative solutions considered in this process.

5.2     Selection of a Preferred Alternative

(a)     Preferred Alternative

Given the foregoing, Alternative 1 – Bridge Rehabilitation was selected as the preferred
solution to the identified problem. The works associated with the preferred alternative are
presented in Table 3.3 and illustrated in Appendix D. This recommendation was presented to,
and supported by, the proponent.

(b)     Class EA Project Schedule

The recommended solution is considered a Schedule "B" project under the terms of the Class EA
document, as the project involves a change to the aesthetic value of a bridge in excess of 40
years old (being the replacement of the steel railings with concrete barrier walls). This project is
approved following the completion of the environmental screening process summarized in
Figure 2.1.

5.3     Final Public Consultation

A Notice of Completion, dated February 10, 2010, will be circulated to local residents,
stakeholders and government review agencies (refer to Appendix C). The notice identifies the
preferred alternative, detailed the availability of the Screening Report and provided the basis for
appeal of the selected alternative solution (i.e., a Part II Order request to the Minister of the
Environment prior to the conclusion of the review period). The Notice will be advertised in the
February 10, 2010 and February 17, 2010 issues of the Huron Expositor and Blyth Citizen.

The review period for the Notice concludes March 12, 2010.

5.4     Approvals

(a)     General

Implementation of the recommended solution is subject to the receipt of all necessary approvals.
Following a review of the existing framework of legislation, and comments from regulatory
agencies it was determined that one formal approval would be required to permit construction of
the proposed works.

(b)    Navigable Waters Protection Act

The affected watercourse is classified as a navigable waterway and, consequently, the proposed
works are subject to the Navigable Waters Protection Act (NWPA). In accordance with the
NWPA requirements, an application has been made to Transport Canada to obtain approval for
Municipality of Huron East

Cranbrook Road Bridge Rehabilitation


the project. The application will set out the measures proposed to minimize the effects of the
project on waterway access and safety. Transport Canada may require additional measures be
incorporated into the construction plan as part of the approvals process.

5.5     Construction Schedule

A general schedule for the construction phase of the project has been prepared based on the
assumption that all necessary approvals will be obtained in the near future. The tentative
schedule for the completion of major tasks is summarized below:

$       Completion of final design drawings and receipt of required approvals (December 2009).
$       Tendering for contracts (January 2010).
$       Initiation of works (May 2010).
$       Completion of works and site restoration (September 2010).

5.6     Probable Capital Costs

The probable capital cost of the project is approximately $360,000 (including engineering). The
proponent intends to finance the capital costs of the work through its public works budget
(incorporated into the annual municipal budget).

6.0     ENVIRONMENTAL COMMITMENTS

As an outcome of this Class EA planning process, the Municipality of Huron East is committed
to carrying out these measures to mitigate the potential environmental impacts of project
implementation:

$       Typical construction mitigation will be prescribed in contract documentation as generally
        presented in Table 4.1, where appropriate (e.g., sediment and erosion controls, site
        restoration).
$       A series of common protective measures will be incorporated into the construction
        specifications to help minimize potential fish habitat impacts.
$       An Ontario Operational Statement Notification Form (Bridge Maintenance) will be
        forwarded to the Fisheries and Oceans Canada and the Maitland Valley Conservation
        Authority.
$       Emergency services (fire, police, ambulance), school transportation services, and
        adjacent property owners will be notified of the construction start date prior to the
        erection of traffic barricades.

7.0     SUMMARY

This report documents the Municipal Class Environmental Assessment process conducted by the
Municipality of Huron East to resolve the identified deficiencies with the Cranbrook Road
Bridge. The preferred solution, to repair the deteriorated bridge components and to construct
solid concrete barrier walls, represents the most practical approach to resolving the defined
problems with the existing structure.
