Executive Summary

Introduction

The Municipality of South Huron is located in the southern portion of Huron County, approximately

45km north of London. The Municipality was amalgamated in 2001 and is comprised of two

townships, Stephen and Usborne, and the Town of Exeter. The Municipality has a population of

9,945 (2011) and has an approximate land area of 425 km2. The Municipality has completed the

South Huron Water and Wastewater Master Plan under the Municipal Class Environmental

Assessment (Class EA) process.

The Master Plan is a component of the Municipality’s strategic plan to improve development

opportunities within these settlement areas through an environmentally sensitive and sustainable

framework for the provision of municipal services for existing and future development.

Master Plan and Public Consultation

The Master Plan is being undertaken in accordance with the Master Planning requirements of the

Municipal Engineers Association (MEA) Municipal Class Environmental Assessment (June 2000, as

amended in 2007, 2011 and 2015). Master Plans are not subject to requests for a Minster’s Order

(Part II Order). However, individual projects identified within a Class EA process can be subject to

a Part II Order. As such, the Master Plan can be implemented following Council approval.

The first step in the Class EA process is to identify the problem or opportunity under consideration.

The following was included in all project notices which defines the problem/opportunity statement

developed for the South Huron Water and Wastewater Master Plan:

“The purpose of the South Huron Water and Wastewater Master Plan is to provide a

complete document that compiles and reviews community and municipal level issues and

opportunities at a planning level. The South Huron Water and Wastewater Master Plan will

be a strategic document in the overall planning for a period of twenty years, specifically

for the provisions of water and wastewater servicing.”

Public, Agency, and First Nation communications were undertaken in accordance with the

requirements of the MEA Class EA process.

Study Area

The study area is the Municipality of South Huron and includes four settlement area classifications

as identified in the Municipality’s Official Plan:

• Primary I includes the Town of Exeter;

• Primary II includes Huron Park, Centralia, and Crediton;


ii

• Secondary includes Corbett, Dashwood, Greenway, Mount Carmel, and Shipka; and

• Tertiary includes Elimville, Kirkton, and Woodham.

Review of Existing Infrastructure

The Municipality is currently serviced with water and wastewater infrastructure. Existing servicing

within the Municipality is illustrated in Appendix 1.1.

Alterative Solutions

As part of the Class EA planning process, reasonable and feasible alternative solutions to the

problem opportunity statement were identified. A qualitative evaluation was used to consider

the suitability of alternative servicing strategies for water and wastewater, and to identify

significant advantages and disadvantages with respect to a set of evaluation criteria identified

for each environmental component (natural environment, social/cultural, technical, and

economic/financial).

Water Servicing Issues and Capital Projects

The key issues identified through this process found throughout the Municipality were:

• Low pressure affecting the provision of fire flow;

• Aging distribution system and watermains;

• The condition of the Exeter Elevated Water Tower;

• Loss of cathodic protection on watermains;

• Inadequate watermains;

• Water system security;

• UV alarms on Point of Entry (POE) units;

• Frequent watermain breaks;

• Water losses;

• Feed to the Turnbull subdivision;

• High water pressures in the Lakeshore area;

• Interconnections with the Municipality of North Middlesex; and


iii

• Aging SCADA system

Table E.1 and Table E.2 contain a list of the issues, capital projects and corresponding timing of

each project for water related infrastructure.

Wastewater Servicing Issues and Capital Projects

The key issues identified through this process throughout the Municipality were:

• Aging infrastructure leading to inflow and infiltration;

• William Street Sanitary Pumping Station bypass events and equipment failures;

• Sewer backups;

• Exeter sewage lagoons aeration system and sand filters;

• Sanitary pumping station condition;

• Aging SCADA system; and

• Limited growth and development.

Table E.3 and Table E.4 contain a list of the issues, capital projects and corresponding timing of

each project for wastewater related infrastructure. In Table E.3, Item E-07, was the replacement

of the sewer main on James Street between Main and Edward Street. This project has been

completed and eliminated from the proposed project list.

1.0 INTRODUCTION

1.1 BACKGROUND

The Municipality of South Huron is located in the southern portion of Huron County, approximately

45 km north of London. The Municipality was amalgamated in 2001 and is comprised of the

Stephen Stephen Ward) and Usborne Townships and the Town of Exeter. The Municipality has a

population of 9,945 (2011) and has an approximate land area of 425 km2. Refer to Figure 1.1 for a

map of the Municipality.

The Master Plan project was planned and implemented in accordance with the Municipal Class

Environmental Assessment (Class EA) process for Master Plans (Municipal Engineers Association,

June 2000, as amended in 2007, 2011 and 2015).

The Master Plan for the Municipality is a strategic document in the overall planning for a period of

twenty (20) years and recommendations consist of a series of individual projects grouped into

Priority Projects and Strategic Projects which collectively constitute the preferred Master Plan

scheme. Projects were categorized based on priority and necessity. The priority categories are as

follows:

• Priority Projects (0 – 1 years);

• Strategic Projects (1 – 5 years);

• Strategic Projects (6 – 10 years); and

• Strategic Projects (10 - 20 years).

The Master Plan is a component of the Municipality’s strategic plan to maintain infrastructure and

improve development opportunities within these settlement areas through an environmentally

sensitive and sustainable framework for the provision of municipal services for existing and future

development.

1.2 PROJECT SCOPE & OBJECTIVES

The scope of work being completed as part of this Municipal Class EA includes:

• Background review;

• Technical analysis of each municipal servicing components (municipal water and

wastewater);

• Development of planning level Master Plan solutions for each other municipal services;


Introduction

1.5

• Undertake public consultation in accordance with Phase 1 and 2 of the Class EA process;

and

• Preparation of a Project File.

This Master Plan is a component of the Municipality’s strategic plan to improve the development

opportunities within its settlement areas, through an environmentally sensitive and sustainable

framework for the provisions of municipal services for existing and future infrastructure.

1.3 EXISTING INFRASTRUCTURE

The Master Plan should be reflective of the development and growth goals of the Municipality, in

accordance with the Official Plan. To ensure this, a set of guiding principles and priorities were

developed with consideration for the following:

• Preference for long-term servicing solutions over interim solutions;

• All services to be fully funded through adequate planning, budgeting and identified

revenue streams, development charges, etc.; and

• Servicing solutions should be developed which minimize risk to the Municipality, users, and

others.

A review of existing information which forms the basis for the analysis of the study areas current

infrastructure capabilities and deficiencies was undertaken. Water and wastewater infrastructure

present in the Municipality are listed in Table 1.1Error! Reference source not found.. Existing

servicing within the Municipality is illustrated in Appendix 1.1.

1.3.1 Water Distribution System

The South Huron water distribution system provides service to approximately 8,000 residents in

Exeter, the Township of Stephen and partially to the Township of Usborne. The system consists of

181 km of water mains, booster pumping stations, reservoirs and elevated water towers. The system

is monitored by online analyzers and a Supervisory, Control and Data Acquisition System (SCADA).

Water is supplied by the Lake Huron Primary Water Supply System (LHPWSS). Some residents along

the south boundary of the Municipality are serviced from the adjacent Municipality of North

Middlesex water system; who also obtain their supply from LHPWSS. South Huron also supplies

customers in the Municipality of Bluewater along the north boundary and in the Village of

Dashwood.

1.3.2 Wastewater Treatment Facility and Collection System

The Exeter Wastewater Treatment Facility (WWTF) and South Huron Wastewater Collection System

provides service to approximately 5,000 residents in Crediton, Centralia, Huron Park and Exeter.

The Exeter WWTF is a New Hamburg type sewage lagoon. The collection system consists of

approximately 62 km of sanitary sewers, forcemains and four sanitary pumping stations. The system

is monitored by online analyzers and a SCADA System. The effluent from the WWTF is discharged

into the Ausable River. Residents who are not on municipal sanitary services use private sanitary

septic systems.

The Grand Bend Wastewater Treatment Facility also provides services to customers in South Huron.

Flows are pumped from various sanitary pumping stations both privately and Municipality owned.

The Grand Bend WWTF has recently been upgraded and South Huron is allocated a 35.7% of the

rated capacity and services residents in the Oakwood Park condominiums, Oakwood Park Links

and Grand Cove Estates.

Consultation

2.1

2.0 CONSULTATION

2.1 OVERVIEW

Stantec, in consultation with Municipal staff, has identified stakeholders, agencies and Aboriginal

communities that may have an interest in this study, the methods of contact, and the timing of

contact for this project. This section details the consultation process followed for the Master Plan.

2.2 CLASS ENVIRONMENTAL ASSESSMENT

A Class EA is a planning document which sets out the process that a proponent must follow in

order to meet the requirements of the Environmental Assessment Act (EAA) for a class or category.

Projects are divided into schedules based on the type of project and activity. Schedules are

categorized as A, A+, B, and C regarding the magnitude of their anticipated environmental

impact.

All municipalities in Ontario, including the Municipality of South Huron, are subject to the provisions

of the EAA and its requirements to prepare an Environmental Assessment for applicable public

works projects. The Ontario MEA Municipal Class EA (June 2000, as amended in 2007, 2011 and

2015) document provides municipalities with a five-phase planning procedure approved under

the ESA to plan and undertake all municipal sewage, water, storm water and transportation

projects that occur frequently, are usually limited in scale and have a predictable range of

environmental impacts and applicable mitigation measures.

2.2.1 Schedule A

Schedule A projects are limited in scale, have minimal adverse environmental impacts and

include the majority of municipal sanitary, stormwater and water operations, and maintenance

activities. These projects are pre-approved and therefore may proceed to implementation

without going through the full planning process.

Schedule A projects typically include normal or emergency operation maintenance activities

where the environmental effects of these activities are minimal. Examples of Schedule A projects

include watermain and sewer extensions where all such facilities are located within the municipal

road allowance or an existing utility corridor. As such, these projects are pre-approved and

subsequently do not require any further planning and/or public consultation.

2.2.2 Schedule A+

Schedule A+ projects were introduced as part of the 2007 amendments to the Municipal Class EA

document. This schedule was introduced to ensure that some type of public notification would

occur for pre-approved projects. Although the public is to be notified, no formal public


Consultation

2.2

consultation process is required. The public has the right to comment to municipal staff in their

area; however, considering that the projects are pre-approved there is no appeal process to the

Minister of the Environment and Climate Change on these projects.

2.2.3 Schedule B

Schedule B projects are those which have a potential for adverse environmental impacts. A

screening process must be undertaken which includes consultation with Aboriginal communities,

directly affected public and relevant review agencies. Projects generally include improvements

and minor expansions to existing facilities. The project process must be filed and all

documentation prepared for public and agency review.

Schedule B projects require that Phase 1 and 2 of the Class EA planning process be followed and

a Project File be prepared and submitted for review. If there are no outstanding concerns raised

by the public, review agencies or First Nations communities then the proponent may proceed to

project implementation (Phase 5). However, if the screening process raises a concern that cannot

be resolved, then the Part II Order procedure (formerly referred to as a “bump-up”) may be

invoked. Alternatively, the proponent may voluntarily elect to complete the project as a Schedule

C undertaking.

2.2.4 Schedule C

Schedule C projects have the potential for significant environmental impacts and must follow the

full planning and documentation procedures specified in the Class EA document (Phase 1 to 4).

An Environmental Study Report (ESR) must be prepared and filed for review by the public, review

agencies and First Nations communities. If concerns are raised that cannot be resolved, then the

Part II Order procedure may be invoked. Projects generally include the construction of new

facilities and major expansions to existing facilities.

2.3 PLANNING PROCESS

Figure 2.1 illustrates the process followed in the planning and design of projects covered by a

Municipal Class EA. The figure incorporates steps considered essential for compliance with the

requirements of the ESA that are summarized subsequently.


Consultation

2.3

Figure 2.1: Municipal Class EA Process


Consultation

2.4

There are five key elements in the Class EA planning process. These include:

Phase 1 Identification of problem (deficiency) or opportunity.

Phase 2 Identification of alternative solutions to address the problem or opportunity. Public,

review agency, and First Nations community contact is mandatory during this

phase and input received along with information on the existing environment is

used to establish the preferred solution. It is at this point that the appropriate

Schedule (B or C) is chosen for the undertaking. If Schedule B is chosen, the process

and decisions are then documented in a Project File. Schedule C projects proceed

through the following phases.

Phase 3 Examination of alternative methods of implementing the preferred solution

established in Phase 2. This decision is based on the existing environment, public,

review agency and First Nations input; anticipated environmental effects and

methods of minimizing negative effects; and maximizing positive effects.

Phase 4 Preparation of an Environmental Study Report summarizing the rationale, planning,

design and consultation process of the project through Phases 1 to 3. The ESR is

then made available for public, agency and First Nations review.

Phase 5 Completion of contract drawings and documents; construction and operation to

proceed. Construction is to be monitored for adherence to environmental

provisions and commitments. Monitoring during operation may be necessary if

there are special conditions.

The MEA Class EA document also serves as a public statement of the decision making process

followed by municipalities for the planning and implementation of necessary infrastructure.

The complexity of each project is based on the level of investigation, environmental effects,

technical considerations and agency, Aboriginal communities, and public input, which may

affect the selection of the project schedule. It is the responsibility of the proponent to determine

and/or customize the planning process to meet the projects consultation and technical needs

based on the complexity of the issues.

The Class EA process is a decision making process to promote good environmental assessment

planning, with key features being:

• Early consultation;

• Consideration of reasonable range of alternatives;

• Assessment of environmental effects;

• Systematic evaluation of alternatives; and


Consultation

2.5

• Clear documentation and traceable decision making.

2.4 MASTER PLAN APPROACH

The Master Plan is being undertaken in accordance with the Master Planning requirements of the

MEA Municipal Class EA (June 2000, as amended in 2007, 2011, and 2015). Master Plans are not

subject to requests from the public, agencies or First Nations communities for a Minister’s Order

(Part II Order).

The MEA offers four approaches for undertaking a Master Plan and based on a review of the

Municipal Class EA, Approach #2 appears to be the most accurate. Approach #2 allows for the

preparation of a Master Plan document at the conclusion of Phases 1 and 2 of the Municipal Class

EA process where the level of investigation, consultation and documentation are sufficient to fulfill

the requirements for Schedule B projects. Accordingly, the final public notice for the Master Plan

could become the Notice of Completion for the Schedule B projects within it. Any Schedule C

projects, however, would have to fulfill Phases 3 and 4 prior to filing an ESR for public review. The

Master Plan would provide the basis for future investigations for the specific Schedule C projects

identified within it.

2.5 STAKEHOLDER CONSULTATION

The following potential stakeholders were included:

• Public: this includes individual members of the public including property owners who may

be affected by the project; individual citizens who may have a general interest in the

project; special interest groups; community representatives; and developers.

• Review Agencies: this includes government agencies that represent the policy positions of

their respective departments; ministries; authorities or agencies.

The role of the members of the public with an interest in the study is to provide background

information, to advise the proponent of their support and concerns, and to review and provide

comments and input about the study findings (as the project progresses). Members of the public

with an interest in the study can ask to be placed on the mailing list to receive notification(s) of

the consultation opportunities for this project.

Members of the public were notified of project commencement and were invited to attend one

Public Information Centre (PIC) by way of notices published in two local area newspapers and on

the Municipality’s website.

A list of relevant public and agency contacts was developed at the onset of the project.

Throughout the process, these contacts were sent letters notifying them of the project progress.

Appendix 2.1 contains the contact list developed for this project. Appendix 2.2 contains public

and agency responses.


Consultation

2.6

2.6 ABORIGINAL CONSULTATION

A list of relevant Aboriginal communities was developed at the onset of the project. Throughout

the process, these communities were provided with letters notifying them of project

commencement and an invitation to attend the PIC. The following nine (9) communities were

engaged as part of the consultation process:

• Chippewas of the Thames First Nation;

• Oneida Nation of the Thames;

• Munsee-Delaware Nation;

• Delaware Nation;

• Bkejwanong Territory (Walpole Island);

• Caldwell First Nation;

• Chippewas of Kettle and Stony Point First Nation;

• Aamjiwnaang First Nations; and

• Metis Nation of Ontario.

At the request of the Caldwell First Nation Community, Stantec and South Huron’s Environmental

Services Director met with their Chief to discuss the material presented at the PIC. The meeting

was on December 14, 2015 in Leamington, Ontario at the Caldwell First Nation office.

At the conclusion of the study, project information will be sent to the above listed communities for

their review and to request final project comments, as outlined in the Aboriginal Communications

Log. Appendix 2.3 contains the Aboriginal Communications Log which was completed for this

project to document the consultation process with Aboriginal communities contacted as part of

the Class EA process. Appendix 2.4 contains a copy of each response received.

2.7 PUBLIC INFORMATION CENTRES

Public Information Centres (PIC) are a method to communicate with the general public,

interested parties, review agencies and First Nations communities. For this project one PIC was

held in two locations. The Municipality covers a large geographic area; therefore the PIC was

advertised in the Exeter Times Advocate and the Lakeshore Advance to ensure the notice

reached all communities.

Due to the large area the Municipality covers, the PIC was held in two separate locations on two

different dates. The first opportunity for the public to engage with the project was on December


Consultation

2.7

9, 2015 from 6:00 pm to 8:00 pm at the Crediton Community Centre in Crediton, Ontario. The

second opportunity was December 10, 2015 from 6:00 pm to 8:00 pm at the South Huron

Recreation Centre in Exeter, Ontario. Both PICs were held as a drop in format with display boards

to introduce agencies, stakeholders, First Nations communities and the public to the project.

Comment sheets were available, as well as an attendance log for people who were interested in

being a part of the mailing list for future communications about the project. Two (2) people signed

the attendance log at the Crediton PIC and four (4) people signed the attendance log at the

Exeter PIC. No comment sheets were submitted at either PIC. Copies of PIC material can be found

in Appendix 2.5

2.8 NOTICES

The Notice of Commencement and Notice of Public Information Centre were published in two

separate news publications; the Exeter Times Advocate and the Lakeshore Advance. The Notice

of Commencement was published on November 4, 2015 and the Notice of Public Information

Centre was published on November 18, 2015 in both news publications and posted on the

Municipality’s website. In addition, both notices were mailed via Canada Post to all project

contacts on the contact list.

The Notice of Completion was posted on the Municipality’s website, published in two separate

news publications (the Exeter Times Advocate and the Lakeshore Advance) and sent out to

agencies and all project contacts via Canada Post. The Notice of Completion informed them the

South Huron Water and Wastewater Master Servicing Plan had been completed. Copies of all

notices are included in Appendix 2.6.

2.9 INTENT OF REPORT

The intent of this report is to outline the steps that the proponent (Municipality of South Huron) has

taken to satisfy the requirements of the Municipal Class EA planning and design process for

Schedule B projects. The report should detail the following:

• Background to the project and earlier studies;

• Nature and extent of the problem and/or opportunity, explain the source of the concerns

or issues and the need for solutions;

• Description/inventory of the environment;

• Identify solutions that are possible and define a preferred solution; and

• Identify the cost to implement the preferred solution.

The MEA Class EA process currently allows a 10-year window for implementation following

completion of the Class EA.


Phase 1 – Problem or Opportunity

3.1

3.0 PHASE 1 – PROBLEM OR OPPORTUNITY

3.1 PROBLEM / OPPORTUNITY STATEMENT

The first step in the Class EA process is to identify the problem/opportunity under consideration.

The following is the problem statement for this project:

“The purpose of the South Huron Water and Wastewater Master Plan is to provide a

complete document that compiles and reviews community and municipal level issues and

opportunities at a planning level. The South Huron Water and Wastewater Master Plan will

be a strategic document in the overall planning for a period of twenty years, specifically

for the provisions of water and wastewater servicing.”

3.2 GUIDING PRINCIPLES

The following guiding principles were developed for the Master Plan:

• The Master Plan is developed in a logical, consistent, and fair manner that reflects the

values of the Municipality of South Huron (Council, staff, community);

• The Master Plan should align with and build upon the goals and objectives for the

Municipality with respect to servicing of existing and growth areas as noted in the Official

Plan;

• The Master Plan should align with the Municipal Servicing Objectives defined in the Official

Plan ensuring that servicing is provided in a sustainable and financially viable manner and

that planned growth is accommodated through the efficient use of existing municipal

infrastructure;

• The Master Plan developed meets the requirements of current regulations and establishes

a proactive plan to achieve compliance with regulations to be phased in by the federal

and provincial government;

• The Master Plan addresses the state and condition of current infrastructure as well as future

infrastructure needs in order to provide the Municipality with an overall blueprint for

infrastructure management;

• Technical analysis based on data collection is undertaken to provide an understanding of

key systems under the expected range of conditions over the study period to the level

required for decisions to be made;

• Key problems and opportunities facing the Municipality with regard to water and

wastewater infrastructure are properly identified, including opportunities to coordinate

work with other capital projects;



3.2

• Past work, current knowledge and future trends and technology are adequately analyzed

and identified to the Municipality;

• Cost effective, sustainable, and timely solutions are developed; and

• For the Municipality to have an interdepartmental consensus as to the Master Plan strategy

based on Stantec’s work.

3.3 POPULATION PROJECTIONS

Population data was taken from Statistics Canada Census Data (2011) and the Ministry of Finance,

Ontario Growth Projections (2014). There continues to be a slight increase in the population in the

Town of Exeter, but a very small decline in the Municipality as a whole. It is projected that the

Municipality will have a population decrease of 0.07% and Exeter will have a population increase

of 0.5% over the twenty (20) year planning period.

2036 5,422 134

Total

637

These projections are lower than the population projections in the Dillion Consulting

Comprehensive Growth Review (2007). After the report was written, industrial factories closed in



3.3

Exeter which is likely contributing to the slower growth in Exeter and the declining population in

the Municipality.


Policy and Planning Documents

4.1

4.0 POLICY AND PLANNING DOCUMENTS

4.1 POLICY DOCUMENTS

4.1.1 The Planning Act (2005)

The Planning Act (2005) sets out the ground rules for land use planning in Ontario and describes

how land uses may be controlled, and who may control them. Pursuant to the Planning Act, the

Province of Ontario is the primary planning authority in Ontario. The Planning Act enables the

Province to delegate some of its planning authority to the upper-tier municipalities (i.e., counties

and regional/district municipalities, as well as planning boards) while retaining control through the

approval process. Municipalities must conform to approved policies of the Provincial government

and its agencies. Provincial ministries, municipal councils, planners, and other stakeholders

implement the Act when such actions include:

• Preparing Official Plans and planning policies that guide future development considering

provincial interests, such as protecting and managing natural resources; and

• Regulating and controlling land uses through zoning by-laws and minor variances.

4.1.2 Provincial Policy Statement (2014)

The Provincial Policy Statement (PPS) is the complimentary policy document to the Planning Act.

Issued under the authority of Section 3 of the Planning Act, the PPS provides direction on matters

of provincial interest related to land use planning and development, and promotes the provincial

“policy-led” planning system that recognizes and addresses the complex interrelationship among

environmental, economic, and social factors in land use planning. The Planning Act requires that

the PPS be reviewed periodically to ensure its policies are still effective. The new 2014 PPS provides

for enhanced protection of the environment by identifying the significance of the natural heritage

system and water resources, including natural hazards and water quality, air quality and energy

use.

The Provincial Policy Statement provides direction for appropriate development while protecting

resources of provincial interest, public health and safety, and the quality of the natural and built

environment. The Provincial Policy Statement supports improved land use planning and

management, which contributes to a more effective and efficient land use planning system.

The policies of the Provincial Policy Statement may be complemented by provincial plans or by

locally generated policies regarding matters of municipal interest. Provincial plans and municipal

Official Plans provide a framework for comprehensive, integrated, place-based and long-term

planning that supports and integrates the principles of strong communities, a clean and healthy

environment and economic growth, for the long term.



4.2

Relevant excerpts pertaining to the Master Servicing Plan from the Provincial Policy Statement are

found below, but are not limited to the following:

Settlement Areas (Section 1.1.3)

• Section 1.1.3.8 b: Infrastructure and public service facilities which are planned or available

are suitable for the development over the long term, are financially viable over their life

cycle, and protect public health and safety and the natural environment.

Infrastructure and Public Service Facilities (Section 1.6)

• Section 1.6.1: Infrastructure shall be provided in a coordinated, efficient, and cost-

effective manner that considers impacts from climate change while accommodating

projected needs. Planning for infrastructure shall be coordinated and integrated with land

use planning so that they are financially viable over their life cycle, which may be

demonstrated through asset management planning and available to meet current and

projected needs.

• Section 1.6.3 a: Before consideration is given to developing new infrastructure, the use of

existing infrastructure should be optimized.

Sewage, Water and Stormwater (Section 1.6.6)

• Section 1.6.6.1: Planning for sewage and water services shall direct and accommodate

expected growth in a manner that promotes the efficient use and optimization of existing

municipal sewage services and municipal water services, and ensure that these systems

are provided in a manner that can be sustained by the water resources upon which such

services rely, is feasible, finically viable, complies with all regulatory requirements, and

protects human health and the natural environment. Planning should be in accordance

with the servicing hierarchy outlined through policies 1.6.6.2, 1.6.6.3, 1.6.6.4 and 1.6.6.5.

• Section 1.6.6.2: Municipal sewage services and municipal water services are the preferred

form of servicing for settlement areas.

• Section 1.6.6.4: In settlement areas, individual on-site sewage services and individual on-

site water services may only be used for infilling and minor rounding out of existing

development.

• Section 1.6.6.5: Partial services shall only be permitted within settlement areas to allow for

infilling and minor rounding out of existing development on partial services if site conditions

are suitable for the long-term provision of such services with no negative impacts.

• Section 1.6.6.6: Planning authorities may allow lot creation only if there is confirmation of

sufficient reserve sewage system capacity and reserve water system capacity within

municipal sewage services and municipal water services. The determination of sufficient



4.3

reserve sewage system capacity shall include treatment capacity for hauled sewage from

private communal sewage services and individual on-site sewage services.

4.1.3 Municipality of South Huron Official Plan

The purpose of the Official Plan is to:

• Develop a land use planning program that maximizes compatibility and synergies

between different land uses and strives to minimize potential conflicts between different

land uses;

• Ensure that future development and decisions in the Municipality are in keeping with the

vision, goals and policies of this Plan;

• Create a planning environment that addresses the needs and aspirations of the

community;

• Build a vision for the future of the Municipality that is agreed upon by the community and

that the community has an active role in its implementation;

• Create a forum for ongoing community-based dialogue in the design, implementation,

and review of this Official Plan; and

• Provide for capital works programs and implementation of Provincial Legislation.

The goals and policies of the Official Plan were established primarily to guide the physical

development of the Municipality while having regard to relevant social, economic and

environmental matters. Relevant sections for the Master Plan are listed below, but are not limited

to the following:

Settlement Area – Definitions (Section 7.2)

• Primary Settlement Areas:

o South Huron’s largest urban centers are considered primary settlement areas.

These communities have full municipal water and sewer services. These areas are

intended to be the primary location for growth and development and offer a full

range of amenities and employment areas.

o Exeter is a Primary I (PI) Settlement Area because it is serviced by municipal water

and sewer, and provides a broad range of employment opportunities and

community services.



4.4

o Crediton, Centralia, Huron Park and parts of the Port Blake Planning Area are

Primary II (PII) Settlement Areas because they are fully serviced communities and

have potential to accommodate growth, but with less capacity than Exeter.

• Secondary Settlement Areas:

o Corbett, Dashwood, Greenway, Mount Carmel and Shipka are secondary

settlement areas because they are serviced by municipal water only. These areas

are intended to accommodate a limited amount of residential growth, new

community facilities and employment uses.

• Tertiary Settlement Areas:

o Elimville, Kirkton and Woodham are tertiary settlement areas because they are

serviced by individual or private communal on-site services. Development in these

areas will be small scale and limited to infilling and rounding out.

• Lakeshore Residential areas are also considered settlement areas. Limited growth is

permitted in these areas. However, unlike other settlement areas, Lakeshore Residential

areas are not intended to contain the same range of land uses found in other settlement

areas. Port Blake Planning Area contains all of South Huron’s Lakeshore Residential Area.

General Settlement Area Goals (Section 7.3)

The following goals are established for South Huron’s settlement areas:

1. Growth shall be directed first to primary settlement areas with existing municipal sewer and

water services;

2. Growth within secondary and tertiary settlement areas will primarily be infill and rounding

out, based on available services;

3. Applications for new residential development will be required to demonstrate how it helps

to achieve affordable housing and intensification targets; and

4. Before considering an expansion to any settlement area boundary, intensification and infill

development will be encouraged within existing urban settlement areas, especially where

municipal water and sewer is available.

General Settlement Area Policies – Growth Allocation (Section 7.4.1)

The primary settlement areas (PI and PII) of Exeter, Crediton, Centralia, Huron Park, and parts of

Port Blake will continue to be the focus of development activity in South Huron over the long term.



4.5

Growth and development will be directed first to settlement areas with full municipal services.

Opportunities in secondary and tertiary settlement areas will generally be for infilling, rounding out

and providing limited community facilities, commercial and employment lands consistent with the

rural character of the community.

4.2 DESIGN SPECIFICATIONS

Design standards and specifications were reviewed and considered in the development of the

Master Plan.

4.2.1 MOECC Guideline D-5

MOECC Guideline D-5 (Planning for Sewage and Water Services) is intended to guide municipal

planning for wastewater and water servicing. It describes an approach for municipal planning

for wastewater and water services to ensure an acceptable quantity and quality of water supply

and the proper collection, treatment and disposal of wastewater for development. It is consistent

with the provincial goal to manage growth and change to foster communities that are socially,

economically, environmentally, and culturally healthy, and that make efficient use of land, new

and existing infrastructure, and public service facilities.

This document states that a hierarchy of servicing preferences should be adopted within the

development of Official Plans and Master Plans. The Ministry states that development on full

municipal services is to be the preferred mode of servicing where there is sufficient uncommitted

reserve capacity or where there is the capability for full municipal services to be expanded. New

development should be directed to settlement areas with existing full municipal services or to

where there has been a commitment to new full municipal services consistent with the Provincial

Policy Statement.

4.2.2 MOECC Guideline D-2

MOECC Guideline D-2 (Compatibility between Sewage Treatment and Sensitive Land Use)

recommends minimum separation distances between new residential developments and other

sensitive land uses and existing sewage treatment facilities. The guideline applies to all

applications for Certificates of Approval for new and expanding municipal wastewater treatment

facilities.

Separation distances are measured from the periphery of the noise/odour producing

source/structure to the property line of the sensitive land use. When new facilities are proposed,

an adequate buffer area should be acquired as part of the project. In the case where an

adequate buffer has not been acquired, more effective noise and odour mitigation are necessary

to provide an optimum level of protection between the sewage treatment facilities and adjacent

sensitive land uses. Consideration should be given to silencing specific sources of noise, covering

certain sections of the plant, and treating collected gases. In some cases, a combination of

distance, covering and treatment may be required.



4.6

For sewage treatment plants with a capacity equal or less than 500 m3/d, the recommended

separation distance is 100 m. A separation distance of less than 100 m may be permitted, however

a qualified professional must produce a study showing the feasibility of the distance based on

noise reduction equipment, degree and type of odour mitigation measures and any other

contaminants of concerns. Pre-consultation with the MOECC Southwestern Region Office is

recommended under these circumstances. In the course of reviewing a draft plan of a

subdivision, the MOECC Regional Office may request the MOECC Approvals Branch to review any

study which supports a separation distance of less than 100 m.

For sewage treatment plants with a capacity greater than 500 m3/d but less than 25,000 m3/d, the

minimum separation distance shall be 100 m. The recommended separation distance shall be

150 m.
