1.1 Purpose of Certification Guide
This certification guide provides information on the requirements to secure and renew a
wastewater operator licence. The guide provides interpretation of the Licensing of Sewage
Works Operators Regulation, O. Reg. 129/04, made under the Ontario Water Resources Act.
This certification guide is provided for information purposes only. Where there is a discrepancy
between this program guide and O. Reg. 129/04, the regulation prevails. Owners, operating
authorities and operators should refer to O. Reg. 129/04 and the Ontario Water Resources Act for
a complete understanding of their legal responsibilities, and certification compliance
1.2 Certification Program Is Administered by a Third Party
The operator/water quality analyst certification program is administered by a third party under
contract with the Ministry. Presently the third party is the Ontario Water Wastewater
Certification Office (OWWCO), also known as the Certification Program Administrator.
The Certification Program Administrator is responsible for possessing certificate and licence
renewal applications, processing exam applications, coordinating and marking exams, notifying
operators of the need to renew their licence, selling exam study guides, informing operators on
continuing education courses that meet the necessary criteria, and providing information to
Details on how to contact the Certification Program Administrator is provided in section 11 of
1.3 Separate Guide to Completing Certification Forms
Supplementary to this certification guide is a 'Guide to Completing MOE Certification Forms',
which can be found on the website of the Certification Administrator. The guide to completing
forms contains a list of all the forms related to facility classification and operator certification
and licence renewal, and provides instructions on when and how to complete specific forms.
(The forms can also be found on this website).
1.4 Separate Drinking Water Operator Certification Program Guide
A separate program guide for the licensing of drinking water operators and water quality analysts
is available at on the ministry's drinking water portal ( www. Ontario . ca/drinkingwater ) .
1.5 Tips on Reading this Guide
The reference to Director throughout the regulation is reference to a person or persons appointed
by the Minister of the Environment as having the authority to make such decisions. The
'Director' under O. Reg. 128/04 and O. Reg. 129/04 is the Manager of Certification, Training
and Client Services within the Drinking Water Programs Branch, Drinking Water Management
Division, Ministry of the Environment.
The meanings of key terms used in this guide are set out in shaded text within the section in
which the term is used. For exact legal definitions of terms, please refer to the relevant
regulations and the Ontario Water Resources Act.
Policy that supplements O. Reg. 129/04 is contained in separate Guidelines, and can be obtained
from the Certification Program Administrator (see section 11 of this guide for contact
information) or on the ministry's website. However, in some instances, part of the policy has
been included in this guide (in boxes within the relevant section).
1.6 Program Mandate
The certification program establishes occupational standards for operators. It is also intended to
give greater assurance of clean surface water and public health to the residents of Ontario
through ensuring that operators have the education, experience and knowledge to perform their
2 Facilities Governed by O. Reg. 129/04
O. Reg. 129/04 applies to:
a) sewage works that requires a certificate of approval from the ministry under section
53 of the OWRA and that is owned or operated by the Crown or a municipality, if
the sewage received by the sewage works is treated; and
b) a sewage works that requires a certificate of approval from the ministry under
section 53 of the OWRA and that is not owned or operated by the Crown or a
municipality, if the 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 storm water, ground water, surface drainage or land drainage
Exception: This regulation does not apply to on-site (e.g. septic) sewage systems which do not
drain or discharge directly or indirectly into a ditch, drain or storm sewer or a well lake, river,
pond, spring, stream, reservoir or other water or watercourse. Such systems with a design
capacity of less than 10,000 litres per day are regulated under the Ontario Building Code.
Systems greater than 10,000 litres per day capacity do require a certificate of approval from the
ministry, but do not require certified operators (unless otherwise indicated in a certificate of
Generally, this regulation does not apply to sewage systems treating industrial sewage which
discharge directly or indirectly into a ditch, drain or storm sewer or a well lake, river, pond,
spring, stream, reservoir or other water or watercourse. The regulation may apply to such
systems if domestic sewage is also treated separately or if the industrial sewage and domestic
sewage are combined and the treatment process includes treatment of the domestic waste. For
further information please consult with the Certification Program Administrator.
A wastewater collection system that is located on private property is considered a plumbing
system. Plumbing systems do not require classification nor licensed operators.
3 Facility Classification
The owner of a wastewater facility must file an application with the Director to have the
classification of their facility determined. Facilities are classified by assigning classification
points for facility characteristics in the Tables found in Schedule 1 of O. Reg. 129/04. Facilities
are classified as Class 1, Class 2, Class 3 and Class 4. The larger and more operational complex
a facility is the higher classification rating it will receive.
The owner must ensure that the certificate of classification is conspicuously displayed at the
facility or, if this is not practical (e.g. at some collection systems), the certificate should be
displayed at the premises from which the facility is managed.
If the facility is altered or no longer meets the criteria under which it was originally classified,
the owner must apply to have the classification re-determined. Generally, if a wastewater
treatment facility is undergoing an upgrade or expansion and a certificate of approval for an
amendment is submitted, it is recommended that the owner consult with the Certification
Program Administrator to determine if re-classification is required.
Further, the Director may request that a facility have their classification re-determined if the
classification points in Schedule 1 of the regulation have been amended, or the Director is of the
opinion that the facility no longer meets their original classification.
3.1 Facilities that do not Fall Under Provincial Jurisdiction
Wastewater facilities which do not fall under provincial jurisdiction do not require classification
of their facilities (i.e., federal facilities and First Nations facilities). The owner of the facility
may submit an application to the Certification Program Administrator, who will review the
facility and provide a notional classification. This notional classification will indicate what level
and class the facility would be classified as if the facility fell under provincial jurisdiction.
Operators who work in these facilities can be certified, and the experience gained working in
theses facilities will be evaluated for upgrades and renewals, just as all other operators.
4 Certification of Operators
Section 14 (1) of O. Reg. 129/04 requires that the owner of the facility ensure that every operator
employed, or persons performing operational duties in the facility holds a valid licence.
'Operating' duties are those functions typically performed by an operator as described in the
definition of 'operator' below.
This includes a maintenance worker, a laboratory technician, or other employee who is 'on call'
and is expected to perform operating functions when 'called out' to do so.
4.1.1 Functions that Must be Performed by a Certified Operator
An operator is defined by the functions they perform, not by the job title, union affiliation, or
whether or not they are in a supervisory or management position.
a ■ i i i I'liirii'iii ii
Aii operator means a peison who conducts opeiauonal checks ol oi who adjusts, tests, oi evaluates
process that controls the effectiveness or efficiency of a facility and includes a person who adjusts or
directs the flow, pressure or quality of wastewater within the facility, if that person works in a wastewa
A person must be certified as an operator in order to perform the following
functions (also referred to as 'operating' functions).
Note: this list is not a complete list. Other tasks the treatment or
collection of wastewater may also require an operator's licence to
undertake. For additional information, please contact the Certification
• control flow or pressure of wastewater in a facility
• addition of chemicals to treat wastewater using and/or through making
adjustments to treatment equipment
• monitor gauges, meters and control valves related to disinfection, treatment
or collection of wastewater
• conduct operational tests within the facility
• start and stop pumps, engines and generators to control and adjust flow and
• open and close valves and gates, whether done manually or by remote
control (a non-certified person can open and close valves for the purpose of
'exercising' a valve)
• isolate portions of a sewage collection system through the diversion of
sewage for the purposes of repair or maintenance
• maintain logs (e.g. shift logs) or other forms of record-keeping related to
treatment and collection activities in the facility, make entries into such
logs/records including meter and gauge readings
A person does not need to be certified to perform the following functions:
• repair previously isolated treatment equipment or sewers
• cleaning sewers using a method which does not significantly impact the
flow of sewage
A person or contractor that is not certified as a wastewater operator can perform
functions normally required to be done by a certified operator provided they are
being directly supervised by a certified operator, meaning the certified operator
is physically present and monitoring the work being performed. All operational
work is the responsibility of the certified operator.
4.1.2 Types of Operator Licences
Operator licences correspond to the types of facilities:
Type of Facility
Classes of Licences
4.2 Licence Qualifications - Operators- In-Training
An operator-in-training (OIT) licence allows new operators to gain one year of experience
required in order to become a Class I operator.
To secure an OIT licence a person must:
• successfully complete grade 12 or equivalent (see ministry guideline 3.1 for a list of
Grade 12 equivalents); and
• pass an OIT or Class I exam.
An OIT licence allows a person to perform all regular operating functions. However, an OIT
cannot be designated as the overall responsible operator or as an operator-in-charge.
4.2.1 OITs are Valid for Three Years
OIT licences expire at the end of three years from the date it was originally issued. A person
holding a wastewater OIT may renew the licence for an additional 3-year term.
4.3 Licence Qualifications -Class I to IV Licences
The Director will issue an operator's licence provided the applicant meets all of the
qualifications for the specific licence applied for and pays the required fee.
To qualify for an operator's licence, a person must:
• meet education and training requirements;
• meet experience requirements; and
• pass a certification examination.
The higher the level of licence, the more education and experience required. The experience
must be gained in the type of facility corresponding to the licence for which the individual is
applying. For example, if the applicant is applying for a treatment licence, the person must have
experience in a treatment facility. (See Note 6 to Table 2 below for exceptions).
Operating 1 experience is experience performing the functions described in
section 4.1.1 of this guide. For further clarification operating experience means
on-site charge and/or hands-on operating of the facility. On-site charge will only
apply to individuals who make operational decisions and provide detailed
operational instructions to other operators.
The licence qualifications for each type and class of licence are summarized in the following
table (also see Notes to Table immediately following the table).
A description of what constitutes related and different experience is available in a Ministry of the Environment
guideline. 3.4 : Experience as an Operator

Notes to Table:
1. Grade 12 equivalency is generally that described in the box immediately following. For a
detailed description, please refer to the ministry's guideline 3.1.
The following is considered equivalent to having secured grade 12:
a Canadian post secondary diploma or degree
securing the General Educational Development (GED) certificate
a 2-3 year certificate or 3-4 year diploma from a recognized Canadian
university or community college
a secondary school graduation diploma or GED from other Canadian
provinces and territories (CEJEP from Quebec) and the US will be considered
a certificate of apprenticeship from Ontario or other Canadian jurisdictions
• completion of a 2 or 3 year college program related to water or wastewater
successful completion of the first year of a college program in directly related
to water or wastewater (for example engineering technologist or technician)
experience from other countries may be considered as Grade 12 equivalent,
contact the Certification Administrator for details - see section 11 for contact
information, or review guideline 3.1 for more specific information.
2. Only experience gained while certified to do the work will be considered.
3. For the purpose of calculating education or training obtained through continuing
education, 450 hours of education or training equals one year. This translates into 45
Continuing Education Units (CEU), since 1 CEU equals 10 hours of training.
4. Substitute experience for education/training :
a. Class III applicants may substitute up to one year experience as an operator-in-charge
in a Class II, III or IV facility, above that required to meet the experience
qualifications, for one year of education/training (or 450 hours of additional
b. Class IV applicants may substitute up to two years of experience as an operator-in-
charge in a Class III or IV facility, above that required to meet the experience
qualifications, for the two years of additional education/training.
5. Substitute education/training for experience : Class II, III and IV applicants can substitute
education & training (except for elementary and secondary education), above that
required to meet the additional education and training qualifications for up to 50% of the
required operating experience (not applicable for substituting OIC experience).
Eligible substitutions include:
relevant post secondary education such as community college, trade school,
training that meets the 'continuing education' training criteria for purpose of
6. Substitute different experience: Class II, III and IV applicants may be permitted to
substitute experience as an operator in a different system, experience in a system other
than as an operator, or other relevant qualifications, for licence qualifying experience.
However, the Director needs to be satisfied that such experience or qualifications are
relevant to the licence being applied for.
Examples of different experiences that may be considered are:
■ experience gained working in a drinking water system
■ experience gained working in a laboratory conducting tests on drinking
water or wastewater
■ experience gained within a wastewater facility doing electrical or mechanical
maintenance, or work as a technical expert or trades person
The ratio is often 2 to 1 or 3 to 1. For example, 3 years of distribution
experience would be equivalent to one year of treatment experience if applying
for a higher treatment licence.
(See Ministry guideline 3.4 for more detail)
7. Application of part-time experience: The application of part-time experience is defined
in ministry guideline 3.4, and operating experience for contractors is detailed in ministry
Generally an operator, who works in a facility that does not require the operator
to be at the facility full-time but does require the operator to be available full-
time, will receive one year experience credit for each year employed. However,
an operator working part-time in a system requiring full-time operators will
receive credit for the actual time worked.
8. The years of experience indicated in this table are not cumulative. For example, a Class 1
operator is required to obtain 1 year of experience. The Class 2 operator requires a total
of 3 years of experience, which includes the 1 year required to obtain the Class 1.
9. An operator may upgrade their licence only one class higher than the licence they
currently hold, and can only hold a licence one level higher than the highest class of
system for which they are employed.
10. An operator has the choice to challenge the OIT or Class I exam when entering the
program. If the operator does not yet have a year of experience under a valid licence the
operator will receive the OIT licence until this requirement has been met.
11. An operator who holds a Class 1 WWT licence is deemed to hold a Class I WWC
licence, and may apply directly to a Class 2 WWC provided they meet the experience
requirements for that licence (e.g. three years of collection experience).
4.3.1 Exception - Professional Engineer
An owner can employ a professional engineer or a series of professional engineers who do not
hold a wastewater operator licence, as an operator, for up to six months in a 12 month period.
A profession engineer means a professional engineer as defined in the Professional Engineers Act.
4.3.2 Experience Exemption for Professional Engineers
A professional engineer accredited in Ontario does not have to meet the experience qualifications
if the professional engineer obtains a mark of 85% or higher on the exam for the type and class
of licence for which they are applying.
4.3.3 Transferability of Operator Licences
An operator who holds one type of licence may be deemed to hold other licences for the purpose
of being able to work in that facility. The following chart shows this transferability:
Licence Held by Operator
Licence Operator Deemed to Also Hold
Class I to IV Wastewater Treatment
■S Class I Collection licence
Class I to IV Wastewater Collection
Note: The operator does not receive a licence of the type they are deemed to hold.
4.3.4 Conditional Operator Licence
The Director may issue a conditional operator licence for operators holding any type and class of
licence (except for an operator-in-training licence).
The Director may issue a conditional licence if:
• the owner or operating authority that employs or has offered to employ the applicant
satisfies the Director that they cannot obtain the services of an operator of the type and
class required under this regulation (for example, if an owner of a Class III wastewater
treatment facility is unable to find an operator holding a Class III wastewater treatment
• the owner or operating authority gives both the applicant and the Director a written
commitment to help the applicant comply with all the conditions of the facility; and
• the required fee is paid.
A conditional operator's licence is valid only for the facility for which it has been issued. The
operator cannot use it to work in another facility. The Director may impose certain conditions in
a conditional licence. The licence expires three years after it is issued, or on an earlier date
specified on the licence, but may be renewed by the Director, if the renewal requirements are
met. (See section 4.4 of this guide, Licence Renewal below).
Examples of when a conditional licence might be issued by the Director are as
■ when a facility upgrade or expansion changes the classification level of the
facility, and no operator employed in the facility has a licence at the new
classification level of the facility
■ when facilities are unable to hire a person with the required class of licence.
Conditions that may be placed on a conditional licence include, but are not limited
■ the operator meeting specific training requirements in addition to the annual
■ technical support or operational back-up be available to the operator holding the
4.3.5 Operator Licence to be Displayed
The owner or operating authority must clearly display the licence of every operator employed by
them at the operator's workplace, or if this is not practical (such as for a collection system), at
the premises from which the facility is managed.
Under the Agreement on Internal Trade, and Ontario Labour Mobility Act, the Ministry of
Environment recognizes certificates from other Canadian jurisdictions that have certification
programs equal to that held in the Province of Ontario. The Ministry still requires the
completion of the Entry Level Course for the issuance of a class 1 drinking water certificate for
those individuals who are applying from a Canadian jurisdiction which does not have an entry
level program. Contact the certification administrator for more details.
4.4 Licence Renewal
Renewal of an operator licence is the responsibility of the holder of the licence. An expired
licence is not a valid licence. Contravening section 14 of O. Reg. 129/04 - i.e. working as an
operator without holding a valid operator licence - is an offence under the Regulation.
Therefore, it is important that operators notify the Certification Office of a change in address
and renew their licence before it expires.
Generally the certification office issues a renewal notice and application form to an operator
ninety (90) days prior to the date when their licence expires. Operators who apply for licence
renewal, meet the renewal qualifications, and pay the required fee will receive a new licence
containing the new expiry date.
4.4.2 Renewal of Operator Licences
Operator licences expire every three years. To qualify for renewal, the operator must have:
a. experience in the previous 5 years working as an operator in a facility or related
In general related experience includes a role in the drinking water and
wastewater industry that enables a person to remain knowledgeable and current
on wastewater treatment or collection equipment and methods.
For example, an operator who becomes a drinking water supervisor, trainer or
technical expert would meet the experience requirement during the time that they
are actively engaged in such role.
Other related experience could include experience as an electrical/mechanical or
maintenance employee of the wastewater system, or as a laboratory technician or
scientist who tests water.
See ministry guideline 3.4 for more detail on related experience.
b. pay the required fee.
For a conditional operator's licence to be renewed, the applicant for renewal must also have met
the conditions of the conditional licence.
4.4.3 Training Requirements
The owner of a facility shall ensure that every operator employed in the facility is given at least
40 hours of training every year.
The training may include, for example, training in new or revised operating procedures, reviews
of existing operating procedures, training in safety, and training on studies of information and
technical skills related to environmental subjects.
The owner shall ensure that records are maintained of the training given under this section. Such
records are to include the names and positions of the operators who attend the training, the date
of each training session, the duration and the subjects covered. The owner shall submit copies or
summaries of the records to the Director upon request.
Operators who hold both drinking water and wastewater certificates/licences must meet the
training requirements for both O. Reg. 128/04 and O. Reg. 129/04. Generally training on topics
related to that of a drinking water operator may be used to meet both the requirements of O. Reg.
128/04 and O. Reg. 129/04. Training on topics specific to wastewater may only be used to meet
the requirements for O. Reg. 129/04.
Training records do not have to be submitted at that time of renewal. Records should be
maintained in the event the Ministry requests copies.
Training may not be pro-rated for part time operators (a full 40 hours is required). In addition,
training may not be averaged between years.
4.5 Re-issuance of Operator Licence after It Expires
If the renewal application is made within five years of the expiry date , the applicant must:
• meet the normal licence renewal requirements.
If the renewal application is made more than five years after the expiry date, the applicant must:
• meet the qualifications in Schedule 2 for that type of Class of licence (including passing the
4.6 Replacement of Licence
The Director may issue a replacement licence if an operator's licence has been lost or destroyed,
or if the operator's name has changed and the original licence is returned to the Director. A fee
will be charged.
4.7 Refusal to Issue or Renew an Operator's Licence
The Director may refuse to issue or renew an operator's licence if:
• any of the circumstances under which the Director can revoke or suspend a licence under
• the licence to be renewed was revoked or suspended;
• the applicant is a holder of a wastewater operator's licence under O. Reg. 129/04 that was
suspended or that the Director is authorized to revoke or suspend.
4.8 Revocation or Suspension of an Operator's Licence
The Director may revoke or suspend an operator's licence, including an operator-in-training' s
licence, for reasons described in subsection 11 of O. Reg. 129/04. The Director may issue a
licence of another type and class than the licence suspended or revoked, providing the applicant
meets the necessary qualifications.
The circumstances that might cause a Director to revoke or suspend a licence are:
• The application was fraudulent or contained inaccurate information
• The person was discharged from employment in a facility for gross negligence or for
incompetence in the performance of his or her duties, unless the person has not yet exhausted
the rights of appeal available under a collective agreement 2
• An operator-in-charge has failed to:
> take all steps reasonably necessary to operate the processes within his or her
responsibility in a safe and efficient manner in accordance with the relevant operations
> Ensure the processes within his or her responsibility are measured, monitored, sampled,
and tested in a manner that permits them to be adjusted when necessary;
> Ensure that records are maintained or all adjustments made to the processes within his or
her responsibility; or
> Ensure that all equipment used in the processes within his or her responsibility is properly
monitored, inspected and evaluated and that records of equipment operating status are
prepared and available at the end of every operating shift,
which resulted in:
> the discharge of a pollutant into the natural environment;
> an adverse effect on the health or safety of an individual; or
> an adverse effect on a process in the facility
• The person has failed to meet or has contravened any condition that is set out in his or her
Any licence decision made by the Director under the regulation may be appealed to the
Environmental Review Tribunal. Details on appeal rights are included in all letters issues by the
Director which denies an application for licence.
5 Certification Examinations
5.1 Exam Application
In addition to meeting the experience and education requirements specific to the different
operator licences, the applicant must also pass a certification exam in order to receive a licence.
2 If a person chooses not to appeal within the time required it would have the same effect as having exhausted their
right of appeal.
Applicants may only write examinations one class higher than the class of licence
that they hold. Applicants must wait a minimum of 90 days from the date of
writing to take the next class level exam or to retry an exam after a failure.
Examination application(s) can be secured from the office of the Certification Administrator.
(See Section 11 of this guide for contact information).
A list of the exam dates and locations can be found on the website of the Certification
Administrator (see Section 11 of this guide for contact information).
5.3 Confirmation Letter
The Certification Administrator will send an examination confirmation letter. This letter will
confirm the following details:
the exam to be written (i.e. WTII)
the date and time scheduled for the exam
location of the exam (map included)
materials required to bring to the exam (personal photo ID and calculator)
licence eligibility requirements (details on the documents that need to be submitted in order
to have the licence issued upon passing the examination). This evaluation may be performed
prior to an exam OR when the applicant receives the exam marks.
It is the applicant's responsibility to ensure that he or she is eligible to obtain the next level of
certification prior to applying or writing an exam.
Note: Under normal circumstances, drinking water examinations are scheduled in the morning,
and wastewater examinations are scheduled for the afternoon. You must bring this
confirmation, plus a government issued photo ID and a document with your address to the
examination session or you will not be able to write the exam on that date .
If an operator writes an examination for a licence they have not yet acquired, the examination
mark is valid for five years from the day of completion. For example, if a class III operator
writes his class IV examination, but is not eligible for the class IV licence, that exam mark is
valid for a five year period. For more information on this policy, review ministry guideline
Following notice of having passed the exam (pass is 70%); operators and water quality analysts
may need to submit the appropriate documentation related to other licence qualifying
6 Operating Standards for Facilities
The owner or operating authority of a facility must ensure that every operator employed in that
facility holds a licence applicable to that type of facility, or a conditional licence applicable to
that particular facility.
6.1 Overall Responsible Operator (ORO)
The owner or operating authority must designate an overall responsible operator (ORO) to
ensure that a knowledgeable, experienced staff person is available at all times to provide advice
to all operators working within the facility and to respond to emergencies.
An overall responsible operator means an operator designated as overall responsible operator of a
facility under section 15 ofO. Reg. 129/04
The owner or operating authority of each facility must designate as overall responsible operator,
an operator who holds a licence for that type of facility and that is of the same class as or higher
than the class of that facility. For example, the overall responsible operator of a Class III
wastewater treatment facility must hold a Class III or Class IV wastewater treatment licence.
To 'designate' means to appoint an operator as holding the position of overall
responsible operator. It must be clear to other operators working in the facility, and
to the ministry inspector, who the overall responsible operator is for each shift. The
expectation is that the overall responsible operator would be identified either
through recording the ORO's name in the daily log, through a memo that is posted,
The intent of the regulation is that there be an ORO designated for a facility at all
times. In order to achieve this goal, an owner or operating authority can designate
one operator to be the ORO for particular shifts or days and another operator as the
ORO for the other shifts or days, provided there is only one ORO designated at any
given time (and that whoever is designated as the ORO meets the requirements of
holding a licence for that type of facility, of the same class or higher than that
facility and is fully aware that they are the ORO assigned at that time).
The ORO may have responsibility for more than one facility provided it does not
affect their ability to perform their responsibilities.
The ORO can be off-site; however, he or she must be able to respond immediately
and effectively to an emergency at the site.
If a designated overall responsible operator holding the proper qualifications is absent or unable
to act, the owner or operating authority or, if the owner or operating authority authorizes it, the
overall responsible operator, may designate an operator who holds a licence applicable to that
type of facility and no more than one class lower to act on their behalf (for example, if the
overall responsible operator for a Class IV collection facility is absent, an operator holding a
Class III collection facility licence can act in their place).
Owners/operating authorities of facilities can only rely on "backup" overall responsible operators
for up to 150 days in any 12-month period in a facility. The Director can make an exception if
the Director is satisfied that the owner or operating authority cannot reasonably hire an operator
holding a class of licence as high or higher than the class of facility. The Director must also be
satisfied that extending the time period will not result in a significant risk to the natural
The duties of an overall responsible operator cannot be delegated to an operator-in-training.
6.2 Operator-in-Charge (OIC)
The owner or operating authority of each facility must designate one or more operators-in-charge
An operator-in-charge means an operator or professional engineer who is designated as an operator-in-
chargeofa facility under section 17 ofO. Reg. 129/04.
An operator-in-charge can be any operator, except an operator-in-training.
The owner or operating authority can also designate a professional engineer, who does not have
an operator's licence, as operator-in-charge. However, the owner can only rely on a professional
engineer or series of professional engineers to be the operator-in-charge for up tol80 days in any
A professional engineer means a professional engineer as defined in the Professional Engineers Act
The owner or operating authority must ensure that records are maintained of the amount of time
each operator works as operator-in-charge.
6.2.1 Duties of Operator-in-Charge
An operator-in-charge is authorized to:
• set operational parameters for the facility or for a process that controls the effectiveness
or efficiency of the facility; and
• direct or instruct other operators in the facility to set such operational parameters.
The operator-in-charge shall:
take all steps reasonably necessary to operate the processes within his or her
responsibility in a safe and efficient manner, in accordance with the relevant operations
ensure that the processes within his or her responsibility are measured, monitored,
sampled and tested in a manner that permits them to be adjusted when necessary;
ensure that records are maintained of all adjustments made to the processes within his or
her responsibility; and
ensure that all equipment used in the processes within his or her responsibility is properly
monitored, inspected and evaluated and that records of equipment operating status are
prepared and available at the end of every operating shift.
The main purpose of creating an operator-in-charge (OIC) position is to ensure
that operators securing a higher class of licence have had the experience and
responsibility reflected in the duties of an OIC. For example, to secure a Class III
or IV licence, the operator must have a specific number of years of experience as
For more information on the roles and responsibilities of the ORO and OIC, please review
ministry guideline 5.1.
6.3 Strikes and Lock-outs
During a strike or a lockout involving operators employed in a facility, the Director may direct
that the facility be allowed to operate without the presence of an overall responsible operator or
certified operator for that type of facility. However, the Director must be satisfied the facility
can be operated without risk to human health or the natural environment.
To assist the Director in making such determination, the owner or operating authority
must submit a 'strike plan' containing specific information. Details on the
information required can be secured from the office of the Certification Administrator.
Information on how to prepare for a strike or lock-out can be found in ministry guideline 5.2.
6.4 Record-keeping re: Operation of Facility
The owner or operating authority must ensure that logs or other forms of record-keeping are
available to record information about the operation of the facility.
Entries into such records must be made chronologically. Entries can only be made by the overall
responsible operator or the operator-in-charge or by a person authorized to do so by the owner,
operating authority, overall responsible operator or the operator-in-charge. The person who
makes the entry must be clearly identified on the record.
The operator-in-charge or another authorized person must record the following information on
each operating shift:
• date, time of day the shift began and ended, and number or designation of the shift;
• names of all operators on duty during the shift;
• any departures from normal operating procedures that occurred during the shift and time
• any special instructions that were given during the shift to depart from normal operating
procedures and the person who gave the instructions;
• any unusual or abnormal conditions that were observed in the facility during the shift,
any action that was taken and any conclusions that were drawn from the observations;
• any equipment that was taken out of service or ceased to operate during the shift and any
action taken to maintain or repair equipment during the shift.
The owner or operating authority must ensure that all records are accessible at the facility for at
least two years after the last entry in it has been made. Copies or summaries of the records must
be given to the Director when requested.
6.5 Operators and Maintenance Manuals
The owner or operating authority shall ensure that operators and maintenance personnel must
have ready access to the operations and maintenance manuals that contain the plans, drawings
and process descriptions necessary for the safe and efficient operation of the facility.
7 Owner/Operating Authority Responsibilities
