Sewage Self Assessment
This voluntary and anonymous self-assessment will help you evaluate your facility’s compliance level with Ontario’s sewage-related environmental legislation.
Helpful tips for using this self-assessment
This voluntary and anonymous self-assessment has been developed to help you evaluate your facility’s compliance level with Ontario’s environmental legislation related to private, commercial, and industrial sewage.
Keep the following in mind as you use this self-assessment:
- Your "yes" responses will indicate:
- how knowledgeable you are about the relevant legislation
- how well you may be reducing your impact on the environment
- This self-assessment is designed so you can fill it out at your leisure and save your responses for future reference.
- We recommend that you use your initial responses as a benchmark for your facility’s compliance program. Over time, you can refer back to these responses to ensure you continue to increase the number of "yes" responses as you work towards environmental improvement.
- Once you have completed this self-assessment, save and print the entire document so you have the questions, answers and support information.
Introduction
The Ministry of the Environment, Conservation and Parks (MECP) developed this self-assessment tool to help you evaluate your compliance with Ontario’s sewage-related environmental legislation and standards. The following questions will help you understand these responsibilities.
The self-assessment will answer key questions about your regulatory responsibilities and help you prepare for future inspections that the ministry may conduct at your facility.
MECP is transforming the environmental permissions program by implementing a two path, risk-based process that is consistent with leading jurisdictions across Canada, the U.S. and abroad. Moving to a risk-based framework allows the ministry to focus on environmental protection while making the process more effective and user-friendly for businesses. The new risk-based process includes a self-registration process for certain routine, standard and well-understood sectors and activities. Persons engaging in such sectors/activities may register the sector/activity in the Environmental Activity and Sector Registry (EASR).
For more complex and unique sectors and activities, you can apply for an Environmental Compliance Approval to address your business’s emissions, discharges and wastes with a streamlined single ECAs approval.
Contact your local ministry district office if you have any questions about your facility’s operation.

Section 1.0
Do you need an Environmental Compliance Approval or permit for your sewage works?
Question 1.1: Do you know what legislation requires you to obtain a permission for your sewage works?
(Yes / No)
Environmental Compliance Approval (ECA) replaces the term "Certificate of Approval" under the Environmental Protection Act and the term "approvals" under the Ontario Water Resources Act. The MECP administers both acts.
The ECA process includes the ability to apply for a single ECA that addresses all of a business’s emissions, discharges and wastes. For example, if your facility has more than one type of environmental impact (i.e., discharge to water and air emissions) you can apply for the required approvals in one application. Separate approvals for air, noise and waste are no longer required.
An ECA for sewage works is required under the Ontario Water Resources Act, and issued under the Environmental Protection Act:
- Section 53 of the Ontario Water Resources Act requires approval prior to using, operating, establishing, altering, extending or replacing new or existing sewage works.
- Although the requirement to obtain an ECA for sewage works is in the Ontario Water Resources Act, as of October 31, 2011, ECAs are issued under Section 20.2 of the Environmental Protection Act. Sewage works approvals in effect before October 31, 2011, and their terms and conditions, remain in effect and can be amended, reviewed, suspended and revoked as if they were an ECA.
As an alternative to obtaining approvals, the Environmental Protection Act allows for certain routine, standard and well understood sectors and activities to undergo a self-registration process on the Environmental Activity and Sector Registry (EASR). Activities registered on the EASR must comply with eligibility and operating criteria set out in regulation.
There is currently only one EASR Regulation applicable to sewage discharges: Water Taking (Ontario Regulation 63/16 under the Environmental Protection Act). The EASR is applicable to sewage works used solely for the collection, transmission, treatment and disposal of storm water to dewater one or more dewatered work areas within a construction site. It does not require applicable sewage works be registered, but does require that they be operated in accordance with prescribed requirements. It should be noted that a construction site does not include a site associated with mines, mine development, mine reclamation, pits, or quarries for the purposes of the regulation.
A permit for some sewage systems is required under the Building Code Act:
- Sewage systems, or plumbing, as defined in the Ontario Building Code (Ontario Regulation 332/12 under the Building Code Act), require a permit under Section 10.1 of the Building Code Act instead of an ECA. The Ministry of Municipal Affairs and Housing administers the Building Code Act.
Sections 1.0 and 2.0 of this self-assessment will help you determine if you need an ECA or a permit under the Building Code Act, and whether the sewage works/system is exempt from permission requirements.
Question 1.2: Does your facility collect, transmit, store, treat, or dispose of sewage?
In answering this question, you should consider:
- Are there toilets, sinks, and/or laundry or kitchen facilities at your site?
- Are there works in place for collecting and/or transmitting sewage/stormwater or drainage?
- Do commercial or industrial processes at the facility generate wastewater?
- Are there any holding/storage tanks on the property?
(Yes / No)
Sewage (wastewater) includes everything that you flush down your toilet or rinse down the drain; water that has been used by industries, businesses, institutions (i.e., hospitals); and rainwater and runoff (stormwater) that go down street gutters or flows into surface water.
If your facility collects, transmits, stores, treats or disposes of sewage, there may be legal requirements you need to be aware of.
Question 1.3: Do you know where your sewage goes?
In answering this question, you should consider:
- Is your facility connected to a municipal sanitary sewage collection system?
- Is there equipment to store or treat sewage on your property?
(Yes / No)
If you do not know where your sewage goes, it is your responsibility to determine whether you are the owner of infrastructure designed to collect, transmit, store, treat or dispose of sewage and obtain any necessary approvals/permits.
Private and Commercial Sewage Works
If your facility is located within a municipality or organized area, your sewage may be collected and treated in a communal (e.g., municipal) sewage works. In this case, you likely receive a bill on at least an annual basis to cover the cost of sewage services and the municipality would be responsible for obtaining an ECA and operating the sewage works.
If your facility is located inside a multi-unit building, it is likely that you are serviced by communal sewage works. In this case the municipality (or owner of the building) would be responsible for operating and obtaining any required approvals for the sewage works.
Industrial Sewage Works
If you operate an industrial facility and do not have an agreement with the municipality to allow you to discharge your sewage into a municipal sanitary sewage collection system, you likely own and operate an industrial sewage works that requires an ECA from the MECP.
Subsection 53(6) of the Ontario Water Resources Act states that an ECA is not required for privately-owned sewage works designed to partially treat sewage that is to drain or be discharged into a sanitary sewer (a legal agreement with the owner of the sanitary sewer is required to satisfy this exemption).
An ECA is required for sewage works which discharge into a municipal stormwater sewer.
Question 1.4: Is your sewage works excepted or exempted from the requirement to obtain an Environmental Compliance Approval?
In answering this question, you should consider:
- Is the sewage works part of an activity that requires registration on the Environmental Activity and Sector Registry (EASR)?
- Does the sewage ultimately drain into a sanitary sewer for treatment offsite?
- Is the sewage works defined as a "drainage works" regulated under the Drainage Act?
- Is the main purpose of the sewage works to drain the land for agricultural activity?
- Is the sewage works a stormwater management facility consistent with the Approval Exemptions Regulation (Ontario Regulation 525/98, as amended by Ontario Regulation 214/22) made under the Ontario Water Resources Act?
- Is the sewage works part of a renewable energy project?
(Yes / No)
Sewage works can be excepted or exempted from the requirement to obtain an Environmental Compliance Approval through subsections 53(2) and 53(6) of the Ontario Water Resources Act, the Approval Exemptions Regulation (Ontario Regulation 525/98, as amended by Ontario Regulation 214/22) made under the Ontario Water Resources Act, and Part V.0.1 (Renewable Energy) of the Environmental Protection Act.
Ontario Water Resources Act subsection 53(2) and 53(6) exceptions include:
- A person is engaging in an activity that requires registration on the Environmental Activity Sector Registry.
- Routine maintenance carried out on any sewage works.
- Sewage works from which sewage is not to drain or be discharged directly or indirectly into a ditch, drain or storm sewer or a well, lake, river, pond, spring, stream, reservoir or other water or watercourse.
- Privately-owned sewage works designed to partially treat sewage that is to drain or be discharged into a sanitary sewer (a legal agreement with the owner of the sanitary sewer is required to satisfy this exemption).
- Sewage system subject to the Building Code Act
- Drainage works under the Drainage Act or a sewage works where the main purpose of the works is to drain land for agricultural activity.
- Drainage works under the Funeral, Burial and Cremation Services Act, the Public Transportation and Highway Improvement Act or The Railways Act, being chapter 331 of the Revised Statutes of Ontario, 1950.
- Such sewage works as may be exempted by regulation.
Approval Exemptions Regulation (Ontario Regulation 525/98, as amended by Ontario Regulation 214/22) made under the Ontario Water Resources Act exempts:
- Sewer service connections and appurtenances
- Same size and capacity replacement sewers (not including combined sewers)
- Stormwater management facilities designed to
- serve a single lot or parcel of land (excluding industrial land)
- discharge into a storm sewer (but not a combined sewer)
- Low impact development works located on residential properties (but not if there is a sewage system on the property)
- Foundation drainage works that collect, transmit, treat and dispose permanent drainage from the foundation of buildings (but not if a permit is required and issued under Section 34 of the Act for water taking)
- Sewage works related to the removal of groundwater and storm water during dewatering of construction sites (but not if a permit is required and issued under Section 34 of the Act for water taking, and/or if the activity is required to be registered under the Registry, and/or if an Environmental Compliance Approval and/or Director’s Order is issued to the site under the Environmental Protection Act)
- Ultraviolet treatment to control zebra and quagga mussels in water pipes (but not if chemicals are used)
- A sewage works that is part of a municipal residential system, as defined under Ontario Regulation 170/03 under the Safe Drinking Water Act
- Vegetated filter strip systems that manage runoff as part of an agricultural operation (but not if they are exempt from Part IX.2 of Ontario Regulation 267/03 under the Nutrient Management Act)
- Greenhouse nutrient feedwater only at an agricultural operation and if it can transmit from one agricultural operation to another
Environmental Protection Act Part V.0.1 (Renewable Energy)
- Subsection 47.3(2) of the Environmental Protection Act exempts sewage works associated with renewable energy projects from the Ontario Water Resources Act approval requirement.
- Applicable renewable energy projects are required to obtain a comprehensive Renewable Energy Approval which covers all required ministry approvals for the undertaking (i.e., sewage, air, waste, noise).
Question 1.5: Does your sewage works discharge to surface water or the ground surface?
In answering this question, you should consider:
- Is the sewage, or treated sewage, discharged through a pipe to surface water or on top of the ground?
- Is treated sewage applied to land through spray irrigation?
- Is the sewage treated in a lagoon that does not discharge but allows the liquid to infiltrate the ground surface?
(Yes / No)
You must obtain the appropriate permission from MECP before using, operating, establishing, altering, extending or replacing sewage works which discharge to surface water or the ground surface and do not meet the exception criteria in the Ontario Water Resources Act or the exemptions listed in the Approvals Exemptions Regulation (Ontario Regulation 525/98, as amended by Ontario Regulation 214/22) under the Act.
The services of a qualified consulting firm familiar with sewage works impacts and design are generally required to prepare the documentation necessary to support the ECA application. Obtain these services early in the design and decision-making process so you and your consultant can discuss technical details such as the proposed scope and extent of the supporting information requirements with MECP during pre-application consultation.
Question 1.6: Does your sewage works/system discharge below the ground surface?
In answering this question, you should consider:
- Is your facility located in an area where municipal/communal sewage services are not available?
- Is a discharge point visible on the property?
- Do you have a septic system?
If your sewage works/system discharges below the ground surface, the questions in Section 2.0 will help you identify whether you require an Environmental Compliance Approval from the MECP or a permit under the Building Code Act.
(Yes / No)
Sewage works/systems that discharge below the ground surface (e.g. septic systems) are regulated by the MECP through the Ontario Water Resources Act and Environmental Protection Act, or the Building Code Act administered by the Ministry of Municipal Affairs and Housing, depending on their size and characteristics.
The term "sewage works" is used in the Ontario Water Resources Act and the term "sewage works" is used in the Building Code Act.
Question 1.7: Do you know how to apply for an Environmental Compliance Approval from the MECP?
In answering this question, you should consider:
- Do you know how to apply for an Environmental Compliance Approval, and what resources are available to assist with completing the application?
(Yes / No)
The minimum requirements for an application are set out in the Applications for Environmental Compliance Approvals Regulations (Ontario Regulation 255/11) made under the Environmental Protection Act. Ontario Regulation 255/11 sets out information that the ministry needs before it begins to review the application but does not refer to any of the supporting documentation and technical information that may be required for the technical review of the application.
These documents are useful when preparing to apply for an ECA for a sewage works:
- Guide to Applying for an ECA
- Design Guidelines for Sewage Works, 2008
- Manual of Policy, Procedures and Guidelines for Onsite Sewage Systems, 1982
footnote 1
Complex proposals or site-specific conditions may prompt MECP to ask for information over and above the minimum requirements. The Director has the authority to request such information that is necessary to review the application. Application costs will vary considerably depending on complexity and must be provided with the application when it is submitted for review.
It does not matter if the operations at your facility already exist or if you are in the planning and development stage of a project; an approval is required in both cases.It is strongly recommended that you consult the ministry before submitting your approval application to confirm supporting information requirements and site-specific considerations.
You must comply with all of the conditions listed in any ECA issued to you by the MECP.
Visit the Environmental Compliance Approval webpage for more information about ECAs and how to apply for an ECA.
Question 1.8: Does your sewage works require financial assurance?
In answering this question, you should consider:
- Is your sewage works located in an unorganized area?
- Do you have a responsibility agreement with the local government agency (e.g., municipality, Ministry of Municipal Affairs and Housing) to take over the works in the event of default?
(Yes / No)
Financial Assurance is authorized under Part XII of the Environmental Protection Act and allows Directors to require regulated parties to provide financial security as a condition of a Director’s Order (specific type of control document), Environmental Compliance Approval (ECA) or by regulation.
Where applicable, the ECA application must include an estimate of the required amount of financial assurance. See Financial assurance for environmental protection for information about applicable facilities, requirements, acceptable forms (e.g., cash, irrevocable letter of credit), and calculating the necessary amount of financial assurance.
Financial assurance will not normally be required of other provincial ministries, other public bodies or institutions.
Financial assurance may not be required for communal private and commercial sewage works if a responsibility agreement is in place which requires the municipality, or another governmental organization, to become responsible for the operation and maintenance of the facility in the event of default.
The requirement for financial assurance for other private and commercial sewage works, and industrial sewage works, is at the discretion of the ministry. It will generally be required if:
- the proponent has a poor compliance history
- the review engineer feels there is a need due to the size and/or complexity of the works
- there is a sensitive land use on, or adjacent, to the site
- it is recommended by staff in the local District Office of the MECP
Question 1.9: Are you aware of policy, legislation, and agreements that could impact the design or expansion of your sewage works?
In answering this question, you should consider:
- Is your proposed sewage works consistent with the servicing options identified in municipal planning documents?
- Is the sewage works located within a vulnerable area identified in a source protection plan?
- Is the sewage works located in the Lake Simcoe watershed?
- Is the sewage works located within the Great Lakes watershed?
(Yes / No)
You should be aware of any potential limitations and restrictions, and the impact they may have on your sewage works in terms of both planning and long-term operation.
The Ministry of Municipal Affairs and Housing’s Provincial Policy Statement guides planning authorities by helping to define appropriate servicing options, including the type, location, and number of facilities permitted within a given area.
Site specific effluent discharge requirements specified in MECP approvals are determined using:
- Procedure B-1-5: Deriving Receiving Water Based, Point Source Effluent Requirements for Ontario Waters (for discharges to surface water); and
- Guideline B-7: Incorporation of the Reasonable Use Concept into MOEE Groundwater Management Activities (for groundwater impacts).
These procedures and guidelines also provide the basis for direction provided in control documents which the ministry may issue to address non-compliance, or when impairment of human health and/or the environment is anticipated.
The Clean Water Act and Lake Simcoe Protection Act are geared toward protecting water resources and provide mechanisms for applying stringent requirements and/or prohibiting certain activities in vulnerable areas.
The Clean Water Act gives communities in Ontario the authority to develop source protection plans to protect their municipal sources of drinking water. The ministry’s Source Protection Mapping Tool will help you identify whether your sewage works are located within a source protection area and your local municipality or conservation authority can provide more information about any source protection requirements.
The Great Lakes Protection Act came into effect in November 2015, and provides flexible new tools to help protect and restore the Great Lakes. This includes committing to establishing at least one target to reduce algae levels and creating more opportunities for the public to become involved in protection and restoration.
There are also agreements in place that could impact sewage works around the Great Lakes. These agreements are part of the overall Great Lakes Strategy, and aim to protect and restore habitat, prevent pollution, and clean up areas of concern:
- Canada- Ontario Agreement Respecting the Great Lakes Basin Ecosystem
- Great Lakes – St. Lawrence River Basin Sustainable Water Resources Agreement
Section 2.0
Do you know who regulates your subsurface sewage disposal works?
The decision tree helps users move through this section. Each question in the decision tree follows in text and includes questions to be considered when providing a response.
Decision Tree: Who Regulates Your Subsurface Sewage Disposal Works?
Does your sewage works discharge below the ground surface?
- No: the sewage works requires approval from MECP
- Yes: 2.1 Is the design capacity of your sewage works/system greater than 10,000 L/d?
- Yes: the sewage works requires approval from MECP
- No: 2.2 Is there more than on subsurface sewage disposal works on the same lot or parcel of land, with a combined design capacity greater than 10,000 L/d?
- Yes: the sewage works requires approval from MECP
- No: 2.3 Is your subsurface sewage disposal works/system located on a different lot or parcel of land than the building or buildings it is intended to serve?
- Yes: the sewage works requires approval from MECP
- No: If you answered no to questions 2.1, 2.2, and 2.3 you have a subsurface sewage disposal system regulated under the Building Code Act. Permits are required prior to construction of the majority of systems regulated under the Building Code Act and are typically issued by your local municipality or Health Unit.
Please note: If you respond yes to any of the question in Section 2.0, and you do not meet the exemption of exception criteria discussed in Question 1.4, your subsurface sewage disposal works requires approval from MECP. Approval is required before using, operating, establishing, altering, extending or replacing applicable sewage works.
Question 2.1: Is the design capacity of your sewage works/system greater than 10,000 litres per day?
In answering this question, you should consider:
- What type of facility do you have? Would it be considered residential occupancy or another type of occupancy (e.g., food service operation, doctor's/dentist's office, church)?
(Yes / No)
Onsite sewage disposal works with a design capacity greater than 10,000 litres per day (L/d) require an Environmental Compliance Approval from MECP.
Use Tables 8.2.1.3.A (Residential Occupancy) and 8.2.1.3.B (Other Occupancies) in the Ontario Building Code (Regulation 350 under the Building Code Act) to estimate whether the design capacity of your sewage works is less than or equal to 10,000 L/d
If your onsite sewage disposal works/system has a design capacity less than or equal to 10,000 L/d, the responses to Questions 2.2 and 2.3 need to be considered to determine if approval is required from MECP or a permit is required under the Building Code Act
Question 2.2: Is there more than one onsite sewage disposal works on a lot or parcel of land with a combined design capacity greater than 10,000 litres per day?
In answering this question, you should consider:
- Is the facility serviced by more than one onsite sewage disposal works? If so, what is the total design capacity of all of these works?
(Yes / No)
If there is more than one onsite sewage disposal works on a lot, and they have a combined design capacity greater than 10,000 litres per day (L/d), an Environmental Compliance Approval is required from MECP.
If there is more than one onsite sewage disposal works/systems on a lot, and they have a combined design capacity of 10,000 L/d or less, the responses to Questions 2.1 and 2.3 need to be considered to determine if approval is required from MECP or a permit is required under the Building Code Act.
Question 2.3: Is your onsite sewage disposal works/system located on a different lot or parcel of land than the building or buildings it is intended to serve?
(Yes / No)
Onsite sewage disposal works that are not located on the same lot or parcel of land as the building(s) they are serving require an Environmental Compliance Approval from MECP, regardless of design capacity.
If the onsite sewage disposal works/systems are located wholly within the boundaries of the lot or parcel of land the building(s) they serve the responses to Questions 2.1 and 2.2 need to be considered to determine if approval is required from the MECP or a permit is required under the Building Code Act.
If the answer to all of the questions in Section 2.0 are no, you have an onsite sewage disposal system regulated under the Building Code Act. Permits are required before construction of the majority of systems regulated under the Act and are typically issued by your local municipality or health unit.
Section 3.0
Do you have an existing approval?
Question 3.1: Have you acquired a facility with, or are you thinking about acquiring a facility with, an existing sewage works?
In answering this question, you should consider:
- Does the facility have a sewage works, as defined in Question 1.2?
(Yes / No)
If you are acquiring a facility with an existing sewage works, it is important to make sure that you receive copies of
- All applicable approvals
- Operation and maintenance records
- Past MECP inspection reports (as applicable)
- Copies of any ministry control documents and correspondence.
The owner is responsible for ensuring that all sewage works have, and are operated in compliance with, an Environmental Compliance Approval. When you acquire a sewage works, you become responsible for all obligations associated with the sewage works at the time of purchase.
It is to your benefit to ensure the appropriate ECA is in place, the sewage works is accurately reflected by the ECA and you are aware of any actions required by the ministry. You should also be familiar with monitoring, operational, and maintenance requirements and ongoing costs associated with using the sewage works.
Question 3.2: Has your facility been expanded, or do you suspect it’s been expanded, beyond what was approved?
In answering this question, you should consider:
- Are there sewage works at the facility that are not reflected in the current ECA?
- Are the estimated design flows for the sewage works consistent with the design capacity specified on the approval?
- Have you increased the number of toilets, sinks, laundry facilities?
- Have you recently provided running water to the facility?
- Have you put an addition on a building/structure serviced by the sewage works?
- Has there been a change in an industrial process which has increased water use?
(Yes / No)
Using, operating, establishing, altering, extending, or replacing an applicable sewage works without first obtaining the required ECA is a violation of both the Environmental Protection Act and the Ontario Water Resources Act.
If the sewage works has (or you suspect it has) been extended or altered without the applicable ECA/permit having been obtained, it is the owner’s responsibility to have the sewage works evaluated and to apply for any necessary ECA or amendments.
Question 3.3: Has there been a change in the quality or quantity of sewage?
In answering this question, you should consider:
- Has the use of the facility changed since the sewage works was approved (e.g., addition of a garage or laundromat)?
- Has there been a change in industrial processes, or a new process introduced?
- Has the facility started accepting offsite sewage such as leachate?
- Has the discharge volume increased?
- Has the rate of discharge increased?
(Yes / No)
Information about sewage quality and quantity is required in support of your ECA application, and is a big consideration in determining whether the proposed sewage works is likely to cause adverse human health or environmental impacts. The sewage works ECA is tailored to the specific information provided in support of the ECA application.
Changes in the type of raw sewage (e.g., addition of oil and grease from a mechanic’s garage), or treated sewage (i.e., increase in speed or volume of discharge) may require different or additional treatment/technology than was initially approved.
If there has been a change in the quality or quantity of sewage since the ECA was granted, the ministry recommends you retain the services of an environmental consultant with relevant experience to discuss the nature of the changes and ensure you have the appropriate ECA.
Question 3.4: Are you planning to perform work on your sewage works?
In answering this question, you should consider:
- Are you planning to alter, extend or replace your sewage works?
- Are you planning to conduct routine maintenance activities?
(Yes / No)
An amendment to your sewage works ECA is required before altering, extending or replacing a sewage works.
Operational and maintenance activities do not typically require ECA unless they will result in a change to the sewage works and/or quantity or quality of the sewage being treated or effluent discharged.
If planned operational/maintenance activities will disrupt sewage treatment, contact your local MECP office well in advance of the planned work to discuss the disruption and measures that will be taken to minimize the potential for raw or partially treated sewage to be discharged to the environment while the work is being performed.
Question 3.5: Do you have bypasses and overflows from your sewage works?
In answering this question, you should consider:
- Do you have a collection system as part of your sewage works?
- Do you occasionally bypass components of your sewage works?
- Do you have combined sewers in your collection system?
- Do you have a Pollution Prevention Control Plan or other program in place to minimize sewage bypasses and overflows?
(Yes / No)
Some sewage works ECAs will specifically address bypasses and overflows, and the associated monitoring and reporting requirements during these events.
Generic direction is also specified in:
- Guideline F-5-1 Determination of Treatment Requirements for Municipal and Private Sewage Treatment Works Discharging to Surface Waters
- Guideline F-5-5 Determination of Treatment Requirements for Municipal and Private Combined and Partially Separated Sewer Systems.
Guideline F-5-5 requires each operating authority with a combined sewer system to develop a Pollution Prevention and Control Plan to address the impact of combined sewer overflows.
Question 3.6: Does your facility need to be classified, and do you require a certified operator, in accordance with Ontario Regulation 129/04: Licensing of Sewage Works Operators?
(Yes /No)
Facility classification and licensing of sewage works operators is regulated under the Licensing of Sewage Works Operators Regulation (Ontario Regulation 129/04) made under the Ontario Water Resources Act. All applicable facilities must be classified in accordance with the regulation and comply with operator certification requirements.
The regulation applies to:
- A sewage works which requires ministry approval and is owned or operated by the Crown or a municipality.
- A sewage works which requires ministry approval that is not owned or operated by the Crown or a municipality, if any sewage received by the sewage works is,
- toilet, sink or culinary liquid waste, or
- other sewage of a kind normally discharged from a residential subdivision, other than stormwater, ground water, surface drainage or land drainage.
Unless specified in the facility’s ECA, subsurface sewage disposal works (e.g., septic systems), and industrial sewage works do not need to be classified or have a certified operator.
The operator certification program (and all applicable testing) is administered by the Ontario Water Wastewater Certification Office (OWWCO) on behalf of MECP.
You can get more information about operator certification Operator Training and Certification page.
Question 3.7: Your facility’s sewage works ECA, control documents (as applicable), and legislation, policies and guidelines list things you must do. Has your facility met all of these requirements?
In answering this question, you should consider:
- Does your ECA specify operation and maintenance requirements?
- Does your ECA specify monitoring and reporting requirements and/or effluent limits?
- Are you meeting the limits and monitoring requirements specified in the ministry’s F-series Guidelines (plants that discharge to surface water)?
- Has a control document been issued for your sewage works?
(Yes /No)
Operation and maintenance requirements, monitoring and reporting requirements, and effluent limits can be specified in a number of ways.
This includes
- ECA requirements
- Control documents
- Regulations made under the Environmental Protection Act
- Documents such as the ministry’s F-series Guidelines and related procedures.
MECP has the power under both the Ontario Water Resources Act and the Environmental Protection Act to initiate abatement and enforcement actions if the specified conditions are not being met.
By not following all the Environmental Compliance Approval and regulatory requirements while operating your facility, you may have the potential to cause harm to human health and/or the environment. The ministry will consider violations on a case-by-case basis, guided by the ministry’s compliance policy.
The ministry’s response may include one or more of the following: voluntary abatement, issuing a control document, and/or investigating which may lead to a possible prosecution.
If you have not met, or know you will not be able to meet, a legal requirement related to constructing, operating or maintaining your sewage works, you should contact your local MECP office to discuss how you can bring the facility into compliance.
Question 3.8: Is hauled sewage (septage) generated by the sewage works picked up by carriers and disposed of at sites with the appropriate Environmental Compliance Approvals?
In answering this question, you should consider:
- Does your sewage works generate hauled sewage (e.g., septic system or holding tank)?
- Have you verified that your waste hauler has ECA from MECP to transport waste?
- Do you know where the hauled sewage goes when it leaves your facility?
(Yes / No)
Hauled sewage (septage) is defined as a waste in Ontario Regulation 347: General - Waste Management made under the Environmental Protection Act. Section 27 of the Act requires a MECP ECA for the both the transport (waste management system) and disposal (waste disposal site) of wastes.
It is your responsibility to ensure all hauled sewage removed from your facility is:
- Transported by a carrier with an approved waste management system
- Deposited at an approved waste disposal site or dedicated septage treatment facility (e.g., composting, alkaline stabilization, dewatering trenches).
The ECA number for all carriers and receiving sites should be recorded in your operation and maintenance logs as a best management practice.
Question 3.9: Do you have operation and maintenance programs in place at your facility?
In answering this question, you should consider:
- Do you have an operations and maintenance manual for the sewage works?
- Are procedures (contingency plans) in place to deal with an emergency?
- Are procedures in place to deal with complaints from the public or external parties?
(Yes /No)
Operation and maintenance programs are a typical ECA requirement or condition. One of the primary goals of implementing operation and maintenance programs is to ensure that you limit and maintain your sewage works in accordance with the regulations and your ECA.
Operating procedures required by an ECA usually relate to the proper operation of process and pollution control equipment to minimize the potential to negatively impact the natural environment.
Maintenance manuals outline the nature and frequency of the maintenance to be performed. These manuals should be reviewed regularly and include details on when the maintenance was performed; and documentation (such as a checklist) detailing who services the equipment, what services were performed and when they were performed.
Additional operating procedures and maintenance programs may be required in your ECA and will likely include procedures and programs recommended by the original equipment manufacturer. Refer to the specific condition(s) in your ECA to determine the requirements for your facility.
Operations and maintenance programs should be considered for all sewage works even if they are not required by the ECA. These programs should include, but not be limited to,
- Operating procedures for routine operation
- Inspection programs, including frequency of inspection and the methods or tests employed to detect when maintenance is necessary
- Repair and maintenance programs, including the frequency of repair and maintenance
- Procedures for inspecting and calibrating monitoring equipment (as applicable)
- A spill prevention control and countermeasures plan, consisting of contingency plans and procedures for dealing with equipment breakdowns, potential spills and any other abnormal situation
- Procedures for receiving, responding to, and recording public complaints, including recording any follow up actions taken.
Question 3.10: Have you completed all of the required and recommended actions as a result of any previous inspections completed by the MECP?
(Yes / No)
Facilities are identified for inspection using a risk based process, and may be conducted when:
- Non-compliance items were identified during a previous inspection, and there is a need to verify appropriate corrective actions have been undertaken
- There has not been a previous inspection or there has not been an inspection for a significant period of time
- Spill reports or complaints have been received by the Ministry of the Environment, Conservation and Parks (MECP)
- The sewage works ECA is outdated and may no longer accurately reflects site characteristics
All inspections findings and required actions will be communicated to the owner in the form of an inspection report.
If your facility has been inspected but you do not have the inspection report, you can contact your local ministry district office to obtain a copy.
The ministry will identify required actions in your inspection report that can be based on a number of issues, such as legislative non-compliance or environmental impact. These required actions normally have a completion date by which you must report and verify to the ministry that the identified required work or actions have been completed for your facility. Failure to comply with the required actions resulting from an inspection may cause environmental impacts and could result in further abatement action or charges being laid.
Recommended actions can be based on a number of issues that are not directly related to a legislated requirement; however, these environmental issues are normally preventive in nature. Recommended actions may include, for example, implementing a spill response plan.
Question 3.11: Are you aware of additional legislation that may impact your sewage works?
(Yes / No)
There are numerous regulatory and policy instruments that apply to sewage works in addition to those that have already been discussed:
- The Toxics Reduction Act and the Toxics Reduction Regulation (Ontario Regulation 455/09) apply to Ontario facilities where manufacturing activities or mineral processing activities take place (except physical extraction, crushing and grinding) and the facility is required to provide information under the National Pollutant Release Inventory (NPRI) or the Airborne Contaminant Discharge Monitoring and Reporting Regulation (Ontario Regulation 127/01) made under the Environmental Protection Act for acetone.
- Regulation 267/03 made under the Nutrient Management Act sets rules and guidelines for applying non-agricultural source materials (NASM) to farmland. NASM includes pulp and paper biosolids and sewage biosolids.
- The Environmental Penalties Regulation (Ontario Regulation 222/07) made under the Environmental Protection Act and Environmental Penalties Regulation (Ontario Regulation 223/07) made under the Ontario Water Resources Act apply to facilities in the nine industrial sectors defined in these regulations and give the ministry the authority to impose monetary penalties when industrial facilities spill. These nine industrial sectors include the metal mining sector, organic chemical manufacturing sector, inorganic chemical sector, industrial minerals sector, electric power generation sector, pulp and paper sector, petroleum sector, metal casting sector, and iron and steel manufacturing sector.
Question 3.12: Do you and your staff (as applicable), know that MECP has a Spills Action Centre that operate 24 hours a day, seven days a week, and can be contacted by phone at 1-800-268-6060 ?
In answering this question, you should consider:
- Is the number for the Spills Action Center prominently displayed at your facility?
- Are there written procedures in place defining what a spill is and outlining the appropriate response to spill events?
(Yes / No)
The ministry’s Spills Action Centre operates 24 hours a day, seven days a week and can be contacted by phone at
When pollutants are spilled into the natural environment, the ministry’s primary role is to ensure that whoever is responsible for the spill mitigates the adverse effect and restores the natural environment in accordance with the applicable environmental legislation and ministry guidelines. Spills are required to be reported immediately or as soon as practicable to the ministry.
The Spills Action Centre receives documents and coordinates responses to province-wide reports of spills and other environmental matters.
“Spills” are defined in Part X of the Environmental Protection Act as the discharge of pollutants into the natural environment originating from a structure, vehicle, or other container, and that are abnormal in quality or quantity in light of all the circumstances of the discharge.
Part X of the Environmental Protection Act requires spills to be reported forthwith by the person having control of the pollutant that is spilled and any person who causes or permits a spill of a pollutant. Part X also requires the owner of the pollutant spilled, and the person who had control of the pollutant spilled to promptly clean up and restore the environment if the spill causes or is likely to cause an adverse effect. There may be other additional measures that have to be taken following a spill, such as correcting the conditions that resulted in a spill and ensuring that preventative measures are implemented. If you believe you may have a spill or another type of environmental emergency, call the Spills Action Centre. Failure to report the spill of a pollutant to the ministry is an offence. It is the responsibility of the owner and controller of the pollutant to clean up a spill. When those under statutory duties cannot or will not respond adequately, the Ministry has the authority under the Environmental Protection Act to order those responsible for the spill to clean up the site. Should they fail to comply with such orders the ministry can undertake the cleanup and recover costs from the polluter.
The Classification and Exemption of Spills and Reporting of Discharges Regulation (Ontario Regulation 675/98) made under the Environmental Protection Act, classifies 11 types of spills, circumstances, industry type or activities that are exempt from all or part of Part X of the Environmental Protection Act duties and responsibilities under specified conditions.
Ontario Regulation 675/98 also encourages those who manage substances that may spill, to evaluate potential risks within their operations and to develop appropriate spill prevention and contingency plans. A “Class X Spill” under Ontario Regulation 675/98 is one addressed in a spill contingency plan that meets certain standards for relatively small and manageable spills.
Under section 91.1 of the Environmental Protection Act, a regulated person shall develop and implement plans to prevent or reduce risk of spills of pollutants, and to prevent, eliminate or ameliorate any adverse effects that result or may result from spills of pollutants. The plan must include:
- Steps to notify the ministry, other public authorities and members of the public who may be affected by the spill.
- Measures to ensure that appropriate equipment, material and personnel are available to respond to a spill.
A spill prevention and contingency plan may provide you with a reporting exemption for spills (under Class X of Ontario Regulation 675/98) and can be used to minimize the impacts and risks of spills. Under the Spill Prevention and Contingency Plan Regulation (Ontario Regulation 224/07) made under the Environmental Protection Act, Spill Prevention and Contingency Plans, the ministry has developed a guideline to assist you with developing and implementing a spill prevention and contingency plan for your facility.
You must fully understand the application of Ontario Regulation 675/98 prior to evaluating whether or not a spill is reportable to the ministry or any other regulatory agency. If you have any questions about spills, refer to the information in this self-assessment and/or contact either the Spills Action Centre or your local MECP district office.
Question 3.13: Are you implementing any beyond compliance measures at your facility?
(Yes / No)
A beyond compliance measure (best management practice) is a plant-based pollution prevention or reduction project that aims to benefit human health or the environment beyond the requirements of the law. Beyond compliance measures may include water conservation to reduce the amount of effluent received by the sewage works, recovery and reuse of process effluents, use of low phosphate/phosphate free soaps, etc.
Beyond compliance measures are proactively put in place to improve operations and minimize the potential for adverse human health and environmental impacts. Examples of best management practices are available from various resources such as the Canadian Water and Wastewater Association, Ontario Onsite Wastewater Association, National Onsite Wastewater Recycling Association, and local Health Units and conservation authorities.
