3. How to submit a generator registration report

On this page Skip this page navigation

Generators of subject waste are required to submit a Generator Registration Report (GRR) through the Registry when they first generate subject waste (see section 18(1) of Regulation 347). If you have determined that you are a generator of subject waste, you must register your waste generation facility by completing a GRR through the Registry. As part of the registration process, you will be creating a site profile that describes your site, the company’s officials and your subject wastes. Your site profile will then become part of your generator registration document which will be posted on the Registry.

If there is any change to the information in the GRR, including changes to a generator’s process(es) or waste stream(s), that requires revisions to the site profile, a supplementary generator registration report must be completed and submitted through the Registry within 15 days of the change (see Section 18(6) of Regulation 347). See Supplementary Generator Registration Report (Revisions) for more information.

If the subject waste identified on the GRR is hazardous waste, the generator must determine if the LDR program requirements apply for each hazardous waste stream identified. LDR requirements are explained in the Land Disposal Restrictions (LDR) section. Generators whose waste is subject to the LDR program should also refer to the LDR Handbook for additional details.

For the purpose of recovering its costs, RPRA may set and require payment of fees (S. 41 RRCEA). These fees are posted on RPRA’s Hazardous Waste Program Registry webpage.

Each waste generation facility requires its own GRR. If a generator operates multiple waste generation facilities, separate GRRs must be submitted for each facility.

The Registry is the online generator registration and manifesting system for generators, carriers and receivers of subject waste. The Registry also provides generators of waste that are subject to LDR requirements with a way of notifying the receiver of the waste’s LDR requirements.

Specific "how to" instructions for how to complete registration through the Registry are provided on RPRA’s Hazardous Waste Program Registry webpage.

Please note that you should not attempt to complete the generator registration process until you have properly characterized your waste and determined your appropriate waste class(es).

3.1 Generator registration

This part of the manual describes all the information required for generators submitting their GRR, with explanations to help generators complete the registration process appropriately.

The following sections describe the information that generators must provide when completing their GRR. Additional information may be required for waste streams that are subject to LDR reporting and notification requirements.

3.1.1 Generator identification

3.1.1.1 Legal company name and company operating name

You must register your company’s full legally registered name, as well as the company’s full operating name, if this is different from the legal name.

3.1.1.2 Waste generation activity

For each facility the generator should identify to the best of their knowledge, whether the operations that are generating the subject waste will continue for an extended period of time (for example, on-going waste generation for the foreseeable future), a short period of time (for example, a fixed term project with an estimated end date), a one-time event (for example, clean-up, maintenance, repair, etc.) and how often waste is expected to be shipped off-site from the facility.

3.1.1.3 (Generator) registration number

The Registry issues a unique generator registration number upon completion of registration. For waste generation facilities based outside Ontario, the generator should provide the registration or notification number assigned by the facility’s local environmental authority.

3.1.1.4 Facility location

You must complete a separate registration for each site where your wastes are generated. The definition of a "site" is provided in Regulation 347 and means one property (including nearby properties that are owned or leased by the same person or company, where passage from one property to the next involves crossing but not traveling along a public highway). You must provide the waste generation facility’s full site address. The Municipality refers to lower tier and single tier municipalities and First Nation communities.

3.1.1.5 Mailing address

You must provide your company’s full mailing address (i.e., street name, number and postal code).

3.1.1.6 Primary hazardous waste contact

The primary hazardous waste contact is the individual who is responsible for managing or is responsible for staff that manages the hazardous waste and LIW at the generation facility. This person should be familiar with all the wastes for which they have management responsibility, should be able to answer technical questions relating to the facility and also be able to provide assistance in the event of an emergency.

3.1.1.7 Alternate contact

The generator may also identify an alternate contact who is also responsible for hazardous waste management at the facility.

3.1.1.8 North American Industry Classification System (NAICS) Codes

It is necessary to identify the industry sectors that the generator facility represents, and the Registry uses the North American Industry Classification System (NAICS) for this purpose. Accordingly, you should enter the six-digit NAICS code which best describes the nature of business at the facility (each generation facility requires a separate NAICS code). While more than one NAICS code may apply to a particular facility, generators should enter the primary NAICS code during registration and, if necessary, up to two additional codes.

For a complete description of NAICS codes and further information, visit Statistics Canada’s website.

3.1.1.9 Ontario liquid industrial/hazardous waste receiver sites

Operators of waste generation facilities that are transfer and processing facilities that are approved to receive subject waste and then ship it off-site are required to register as generators. If you are such a facility you must indicate this during the registration process and provide your ECA number. Most generators in Ontario are not approved as waste receivers.

3.1.1.10 Municipal hazardous or special waste (MHSW) depots and contaminated site remediation

MHSW depots and contaminated sites that generate remediation waste need to be registered, and any subject waste that leaves the site needs to be manifested. MHSW depots and contaminated sites that generate remediation waste and that meet the applicable criteria in sections 3 and 4 of Ontario Regulation 323/22 are not required to pay subject waste fees. Most generators in Ontario are not an operator of an MHSW depot or contaminated site. The Ministry will review generator registrations where the waste generation facility has been identified as an MHSW depot or contaminated site and provide confirmation to the Registrar of RPRA that the applicable criteria have been satisfied under O. Reg. 323/22, in which case no subject fees are required to be paid.

3.1.1.11 MHSW depots

Waste generation facilities that are MHSW depots need to submit a GRR through the Registry.

If your site is a MHSW depot, and the waste generated is solely as a result of collection of MHSW from the general public, please submit a copy of documentation showing your approval to operate an MHSW depot (i.e., ECA) with your Generator Registration Report through the Registry. The subject waste fee exemption may be applied upon the review of a Director in the Ministry, where the Director is satisfied that the generator and the waste meet the requirements in Ontario Regulation 323/22. In some cases, a site that generates subject waste as part of its normal operations may also be a MHSW depot. In this case, you should submit two generator registration reports: (1) a GRR for the collected MHSW wastes; (2) a GRR for the subject wastes that are not collected MHSW waste.

3.1.1.12 Contaminated site remediation

Waste generation facilities that generate waste because of contaminated site remediation need to submit a GRR through the Registry.

If the site is located in Ontario and is contaminated and all your waste results from activities that were carried on at the site for the purpose of remediating contaminated soil or other contaminated materials located on, in, or under the site, please submit supporting documentation that shows the site address, reasons for remediation, sources of contamination, types of wastes generated, expected duration of project, etc. along with the Generator Registration Report through the Registry . In some cases, a waste generation facility that generates subject waste as part of its normal operations may also be a contaminated site. In this case, you should submit two generator registration reports: (1) a GRR for the subject wastes that are the remediation wastes from the contaminated site: (2) a GRR for the other subject wastes that are generated as part of normal operations.

Subject waste fees are required unless the Director is satisfied that the subject waste was generated at a waste generation facility in Ontario as a result of one of the following actions undertaken to remediate contaminated soil or other material in, on or under the soil:

actions to complete a Phase II environmental assessment report
actions to complete a risk assessment
actions to comply with any order issued under the Environmental Protection Act
actions to meet the applicable site condition standards in the Ministry’s "Soil, Ground Water and sediment Standards for Use under Part XV.1 of the Environmental Protection Act
an action that the Director is satisfied was undertaken for a purpose that is consistent with the above purposes

The Ministry has accepted a Phase II environmental assessment report, site specific risk assessment, remediation report, a consultant’s proposal or an order issued under the EPA to clean up the site.

3.1.1.13 On-site management

As part of the registration process, for each waste stream you must indicate if your facility stores, processes or disposes of subject waste on-site. Please note that on-site management does not include the blending, bulking or mixing of wastes. Generators should indicate whether they will be registering a waste as temporarily stored (for more than 90 days but 24 months or less), stored for longer than 24 months (i.e., PCB waste, or waste that is being stored in accordance with an ECA), processed (i.e., treated) or disposed of (for example, incinerated or landfilled) on-site.

3.1.2 Waste identification

You must complete waste identification for each waste stream generated at a facility, even if you will be registering several waste streams using the same waste number (waste class and characterization).

This situation can arise if you have a number of different waste generating processes at your facility that produce similar wastes, or a single waste generating process that produces more than one waste stream that will be registered using the same waste number. In such cases, you need to complete a separate waste identification for each of the waste streams, because the description of the waste and the generating process are different, even though the waste number is the same. For example, you may generate waste from tank bottoms as well as spill clean-up residues that will both be registered using the waste number (for example, 221T). You are required to register these waste streams individually because they come from different sources with different waste descriptions, despite their common waste number, and they should be managed separately at the waste generation facility.

The descriptions provided for the waste and the generating process must be detailed enough for both the generator and Ministry inspectors to be able to readily identify the individual waste streams and their origins, and to correlate the registration information to the specific wastes and generating processes within the waste generation facility. The waste description should differentiate between two processes in a facility where the wastes are managed separately but registered with the same waste number. For example, the waste description for two processes registered using the same waste number might be "wastewater treatment sludge - leachate toxic for X (i.e., identify the constituents)", while the waste stream and generating process description might be "sludge containing heavy metals from process #1, building A" and "sludge containing heavy metals from process #3, building C", respectively.

For each subject waste generated at the waste generation facility, you must identify if the waste is being stored or processed on-site, disposed of on-site or shipped off-site. Where the waste is processed on-site, you may need to register the wastes that entered the process, the processed waste and any residuals from the processing. How the waste is registered depends on its waste characterization, whether it is to be land disposed, and whether it has received any treatment. Figure 4: Registration and other regulatory requirements: Wastes not subject to the LDR program or Figure 5: Registration and other regulatory requirements: Wastes subject to the LDR program will help you to determine if you need to register your waste. Figure 6a and 6b: How to complete the intended waste management portion of the waste generator registration process provides a flowchart to help you to identify how each of your subject wastes should be registered.

3.1.2.1 Waste class

Provide the waste class that you identified during your waste characterization. The Ontario waste class is a three-digit number (for example, 263, 121, etc.).

3.1.2.2 Waste type

You must select a general description of your waste from a predetermined list of examples. Select the one that best describes your waste.

3.1.2.3 Primary characterization

You must provide the primary characterization that you identified when you characterized your waste. The primary characterization is the first characterization of a waste found when you follow the waste characterization flowchart (for example, A, B, C, etc.). If you are registering a de-characterized waste that will be land disposed, and the waste is no longer hazardous but remains subject waste (i.e., regulated constituents in Schedule 6 of Regulation 347 still require treatment before land disposal), the primary characterization is U.

3.1.2.4 Hazardous waste number

From the schedules located in Regulation 347, you will need to obtain the primary hazardous waste number that best describes your waste stream. This is the entry in the first column of each schedule (for example, F007 for spent cyanide plating bath solution from electroplating operations). The hazardous waste number must be entered for all wastes with a primary characterization other than D, P or L. If your waste has more than one characterization, you should use the hazardous waste number associated with the primary characterization. If you are registering a de-characterized waste, you should use the original hazardous waste number for the untreated waste.

3.1.2.5 Physical state

Describe the physical state of the waste stream (i.e., either solid, liquid or gas).

3.1.2.6 Specific gravity

If the physical state of the waste is liquid, you must provide the specific gravity of the waste stream.

3.1.2.7 Waste number

The waste number consists of the three-digit number (Ontario waste class) plus a single letter (primary waste characterization), (for example, 263A, 121L, etc.).

3.1.2.8 Description of waste

You must provide a general description of your waste and, where appropriate, include details such as the colour, principal components, contaminants and contaminant concentrations in the waste.

3.1.2.9 Description of generating process

You must provide a general description of the generating process for the subject waste. Where applicable, you should include details such as a generic process name, feed materials and products. If your waste is generated by pollution control equipment, you should provide a description of the process or operation that generated the discharge or emission.

3.1.2.10 Physical state

Describe the physical state of the waste stream (i.e., either solid, liquid or gas).

3.1.2.11 Specific gravity

If the physical state of the waste is liquid, you must provide the specific gravity of the waste stream.

3.1.2.12 Waste number

The waste number consists of the three-digit number (Ontario waste class) plus a single letter (primary waste characterization), (for example, 263A, 121L, etc.).

3.1.2.13 On-site waste management

Information about the management of waste streams on-site must be provided if your waste generation facility is located in Ontario. On-site waste management activities include: (1) storage for more than 90 days but 24 months or less; (2) storage for a period greater than 24 months; (3), processing and (4) disposal of a waste stream - all at the location where the waste was generated.

These four (4) activities require registration: Please note that a waste stream may be managed and reported in more than one activity (for example, waste is processed on-site and also disposed of on-site); or stored on-site and then sent off-site for disposal.

The GRR does not need to include information about on-site waste handling, bulking of like wastes prior to treatment or disposal, and waste transfer to a waste transportation vehicle.

3.1.2.13.1 (1) On-site storage for more than 90 days but 24 months or less

Generators who temporarily store hazardous waste on site for a period of between 90 days and 24 months must register through the Registry. The registration shall contain information about:

the reason for storing the waste
an estimate of the amount of waste to be stored or expected to be stored
the manner in which the waste is stored
the anticipated manner of disposal of the stored waste
the date upon which the generator began storing the subject waste
whether or not the amount of waste to be stored will increase over time and if so, the expected accumulation rate and maximum amount to be stored

A separate registration must be completed for each waste to be stored on site for longer than 90 days.

3.1.2.13.2 (2) On-site storage for a period longer than 24 months

If a generator stores a waste on site for a period longer than 24 month the generator must provide all the information required for waste stored at a facility for a period between 90 days and 24 months.

In addition, generators must provide the PCB storage site approval number or the ECA number that authorizes the storage of the waste.

When reporting the generator will provide a start date for the storage, and a review date of up to one year, by which time a generator would need to return to the report and confirm the information or make any necessary changes.

3.1.2.13.3 (3) On-site processing

A waste stream that is managed on-site using any of the following activities must be registered under On-site Processing:

processing (waste ECA required)
processing (exempt from the Act, pursuant to Section 17.1 of Regulation 347)

Generators who process subject waste on-site must register it as On-site Processing if:

the subject waste is processed such that the processed waste remains a subject waste, or
the residual from the processing of the waste is a subject waste

Registration of a subject waste is not required if the waste is processed on-site, and as a result of the processing it is no longer a subject waste, and any residual from the processing is not a subject waste.

A subject waste that is processed on-site by any activity that changes the nature of the waste must be registered as On-site Processing. This requirement includes activities such as mixing of different types of waste to carry out treatment (for example, mixing an acid and a base to effect neutralization), and activities that involve adding other materials to treat the waste (for example, chemical oxidation). Processing does not include mixing of like wastes where there is no change in the nature of the waste. If subject wastes are mixed in accordance with an ECA and no processing takes place, the mixed waste should not be registered under On-site Processing.

If an ECA is required for on-site processing of a subject waste, the waste must be registered as On-site Processing (please see the Regulatory Requirements section for information about when an ECA is required to process waste on-site). Processing does not include the activities listed under On-site Disposal (for example, incineration, OWRA facility, etc.).

Generators who process subject waste on-site must identify whether the processing was carried out in accordance with a waste ECA or if the processing did not require a waste ECA in accordance with Section 17.1 of Regulation 347. If a waste ECA was issued for on-site waste management activities, the generator must provide the ECA number.

If either the processed waste or the residual from the waste processing is a subject waste, the generator must submit information about each processed or residual waste stream through the Registry, according to how it will be managed. If the subject waste is to be shipped off-site or further managed on-site after processing, the generator must submit information about each processed waste or residual through the Registry.

The processed waste or residual may have the same waste number as the waste number for the waste at the point of generation or may be different. For example, where more than one waste is processed on-site using the same treatment method, and the resulting processed waste is a subject waste, the generator must:

register each of the waste streams under On-site Processing
register the resulting subject waste, and
add the waste number for the resulting subject waste to all of the waste streams that were registered under On-site Processing

Generators who process hazardous waste on-site are not required to provide information with respect to the land disposal treatment requirements when they register a waste stream as On-site Processing. However, this information may be required when a subject waste is registered for off-site shipment. Generators who process listed wastes and characteristic wastes on-site may be subject to LDR requirements, including the requirement for a waste analysis plan. The generator may also be subject to LDR notification requirements pursuant to Section 84 of Regulation 347 for a waste stream registered as on-site processing, if a characteristic waste was processed to meet the land disposal treatment requirements and will be disposed of off-site (for more information, see the Notification, record-keeping and waste analysis plan requirements section).

When reporting on-site processing for a waste, the generator may provide a date range of up to a year and an estimated quantity to be processed in that date range. The generator must then report the actual quantity before the end of the date range and update the end date if necessary.

3.1.2.13.4 (4) On-site disposal

A waste stream that is managed on-site using any of the following activities must be registered and reported as On-site Disposal:

incineration
thermal treatment (non-incineration)
landfill
landfarm
discharge to sanitary sewer (hazardous discharges only)
OWRA facility (on-site treatment - hazardous waste discharges to final stage only)
use as a waste-derived fuel
other on-site disposal (the generator must identify the disposal method)

If a subject waste is processed on-site or stored prior to on-site disposal, the waste must also be registered and reported as On-site Processing or as Storage, as the case may be.

If an ECA has been issued for on-site disposal of the waste (for example, thermal treatment, landfill, etc.), the generator must provide the ECA number. When reporting on-site disposal, the generator may provide a date range of up to a year and an estimated quantity to be disposed in that date range. The generator must then report the actual quantity at or before the end of the date range and update the end date if necessary.

If the waste stream that is being disposed of on-site was a listed waste or characteristic waste at the point of generation (i.e., all wastes except those with the primary characterizations of L, D and P) and the waste will be land disposed, the generator must confirm that the on-site activities were conducted in accordance with Ontario’s LDR requirements (i.e., meeting the land disposal treatment requirements and preparing a waste analysis plan).

There may be cases where a residual resulting from one of the disposal practices above is a subject waste (for example, residue from the incineration of hazardous waste or from an OWRA facility) that requires further management, either on- or off-site. In such cases, if a subject waste is to be shipped off-site or further processed or disposed of on-site, it must be registered and reported separately as a new waste stream.

3.1.2.14 Off-site waste management

All waste streams that will be shipped off-site must be registered. For waste streams that are hazardous waste (other than PCB (D) or pathological (P) waste) the GRR includes a series of questions to determine if the information contained in the LDR notification form is required. The generator may determine by answering these questions that the LDR Notification part of the GRR does not need to be completed for the waste stream. If so, additional information (for example, ECA number) may be required where indicated. The questions that help to determine if the completion of the LDR notification form is required are provided in Appendix F: Declaration of wastes subject to land disposal restrictions and in Figure 7: Declaration of waste streams subject to land disposal restrictions.

All generators who produce a listed waste or characteristic waste that will be land disposed are required to fill in the LDR portion of the GRR. The LDR notification form has been designed so that it not only meets generator registration requirements but can also be provided by the generator to the receiver to meet the notification requirements (see Section 84 of Regulation 347). The Registry allows generators to complete the LDR notification form and attach it to the first manifest being sent to the receiver or send it to the receiver ahead of the first shipment of the waste stream. Please note, any change to the treatment requirements of the waste stream would require an updated LDR notification form to be provided to the receiver.

Generators are responsible for identifying whether or not their waste is subject to the LDR requirements when they register each waste stream. Although a generator may ask the receiver or carrier of the waste how the waste will be managed and whether it will be land disposed, it is the generator who must determine whether the LDR requirements apply. If generators are uncertain about whether the LDR requirements apply, they should complete the LDR notification form and forward the information to the receiver of the waste.

3.1.5 How to complete the intended waste management portion of the waste generator registration process (text version)

3.1.5.1 On-site storage

Step 1. Do you store waste on-site? Note that:

stored waste includes PCB waste and waste stored in accordance with an ECA
waste stored for more than 90 days requires registration and a Notice to be submitted through the registry (See 17.2 of Regulation 347)

If yes, go to Step 2. If no, go to the On-Site Processing Section.

Step 2. Register each waste stream by completing the on-site storage section. Information about LDR is not required for stored wastes. Proceed to Step 3.

Step 3. Do you have other subject waste to register? If yes, go to On-Site Processing. If no, complete your registration.

3.1.5.2 On-site processing

Step 1. Do you process subject waste on-site? This does not include mixing, blending or bulking where no treatment is involved, or disposal through OWRA facilities, thermal treatment or waste-derived fuel sites. If no, go to On-Site Disposal. If yes, go to the ‘How to Complete the Intended Waste Management Portion of the Waste Generator Registration Process (continued)’ section.

3.1.5.3 On-site disposal

Step 1. Do you dispose of subject waste on-site? Note that on-site disposal includes:

incineration
thermal treatment (non-incineration)
landfill
landfarm
discharge to sanitary sewer (hazardous discharges only)
OWRA facility (hazardous waste discharges to final stage only)
use as a waste-derived fuel
other on-site disposal

If no, go to Off-Site Waste Management. If yes, go to Step 2.

Step 2. Register each waste stream by completing the on-site disposal section.

If waste is land disposed it must meet LDR treatment standards
A LDR notification form is not required

Go to Step 3.

Step 3. If a new waste stream is generated from the disposal of the waste (e.g. incinerator ash, leachate) the new waste stream may also need to be registered. Go to Step 4.

Step 4. Do you have other subject waste to register? If yes, go to the Off-Site Waste Management section. If no, complete your registration.

3.1.5.4 Off-site waste management

Step 1. Register each waste stream to be shipped off-site.

determine if the LDR notification form is required
complete the LDR notification form if applicable

Complete your registration.

3.1.6 How to complete the intended waste management portion of the waste generator registration process (continued)

3.1.6.1 On-site processing (continued)

Step 1. Will the processed waste or any residual waste be land disposed? If yes, go to Step 2. If no, go to Step 3.

Step 2. Is the processed waste or residual from the processing a subject waste? Note that for listed waste the derived from rule applies and both the processed waste and residuals remain subject waste. If yes, go to Step 4. If no, go to Step 5.

Step 3. Is the processed waste or residual from the processing a subject waste? Note that for listed waste the derived from rule applies and both the processed waste and residuals remain subject waste. If no, go to Step 5. If yes, go to Step 6.

Step 4. Register each waste stream entering the process.

A LDR notification form is not required for waste processed on-site. You must also register the processed waste or residual that is subject waste.
If waste is to be land disposed it must meet LDR treatment requirements.

Go to Step 7.

Step 5. No registration of processed waste or residual required. Go to Step 8.

Step 6. Register these wastes based on how they will be managed (e.g. on-site disposal, off-site, storage, etc.).

Registration of wastes entering the process not required.
Registration of the subject wastes from the processing is required.

Go to Step 8.

Step 7. Will the processed waste or residual that is subject waste be stored or further processed on-site? If yes, go to the On-Site Storage section. If no, go to the On-Site Disposal section.

Step 8. Do you have other subject waste to register? If no, complete your registration. If yes, go to the On-Site Disposal section.

3.1.7 Land disposal restrictions notification form

Generators who produce subject waste that is listed waste or characteristic waste that will be shipped off-site for land disposal must complete the LDR notification form containing the information set out below. Please see Appendix E: Generator registration and land disposal restrictions reporting for additional information.

A separate LDR notification form must be completed for each subject waste stream that is generated at the facility and will be land disposed, or where the final disposition of the waste is unknown. Once the form has been completed, it is also the generator’s responsibility to provide the information in the form to the initial receiver of the waste, in accordance with Section 84 of Regulation 347. This can be done by using the Registry, or by providing the required information in a different format.

3.1.7.1 Aqueous or non-aqueous waste for the LDR notification form

Aqueous wastes are wastes that contain less than 1% total organic carbon by weight, and less than 1% total suspended solids by weight. Non-aqueous wastes are wastes that do not meet the criteria for aqueous wastes. You must identify if your waste is aqueous or non-aqueous.

3.1.7.2 Alternate treatment standards

For wastes that are soil or soil mixtures or debris or debris mixtures, generators may choose to meet the alternate treatment standards. If this is your preferred option, you must indicate that alternate treatment standards apply, and indicate whether your waste is a soil or a soil mixture or a debris or a debris mixture. If you indicate that your waste is a debris or a debris mixture, you must indicate what type of debris or debris mixture it is. The types of debris include glass, metal, plastic, rubber, brick, cloth, concrete, paper, pavement, rock, and wood. If the waste is a mixture of debris types, you must list all the types of debris in the mixture.

3.1.8 Figure 7: Declaration of waste streams subject to land disposal restrictions

This flowchart is a graphical representation of the text contained in Appendix F: Declaration of wastes subject to land disposal restrictions. If you are unsure how your waste will be managed once it is sent off-site, you must complete the LDR notification form.

3.1.8.1 Hazardous waste numbers for the LDR notification form

When characterizing your waste stream (please see Determining the Characterization of your Waste Stream) you may have identified multiple characterizations (i.e., the waste may have more than one waste characterization, for example, H and T). For each waste characterization (except for P, D or L), you must provide the following information:

hazardous waste number(s)
for each hazardous waste number, the generic name and associated CAS #
number if the waste is listed in Part A or Part B of Schedules 2, Schedule 3, or Schedule 5 of Regulation 347; or a description of the waste if the waste is listed in Schedule 1 of Regulation 347, and
the treatment sub-category (if applicable)

Any waste generation facility that mixes wastes that are subject to LDR in accordance with Regulation 347 or applicable ECA, must identify all hazardous waste numbers for each individual waste that entered the combined waste stream.

Some facilities (for example, transfer stations) bulk similar wastes together that are subject to LDR and send the bulked waste to a receiver. These facilities must report in the LDR notification form for their operation all of the hazardous waste numbers from the incoming LDR notification forms that they received from generators for each of the wastes that are bulked together.

Similarly, a processing facility that mixes LDR wastes before treatment to meet land disposal treatment requirements must report in its LDR notification form all hazardous waste numbers from the incoming LDR notification forms that were received from generators for the wastes that were mixed.

Failure to report all hazardous waste numbers from the incoming wastes when registering a waste that is made up of mixed, blended, bulked, or processed wastes could constitute dilution (please see the Waste management section for more information on when like wastes can be bulked).

3.1.8.2 Regulated constituents

Generators must provide additional information in this section of the LDR notification form for all listed wastes in Schedule 1, Part A or Part B of Schedule 2 and Schedule 3 and for all characteristic wastes in Schedule 5. For each hazardous waste number, you must list all regulated constituents (i.e., each constituent with a treatment standard) that are known or expected to be present at concentrations at or above the standard at the point of generation. For most characteristic wastes, this requirement includes all regulated constituents listed in Schedule 6 of Regulation 347 that may require treatment. You must also specify the type of characteristic wastes (for example, corrosivity, ignitability, etc.) in this section.

The Registry will provide you with a menu from which you can select the regulated constituents. The choices in each menu are based on the hazardous waste number(s) you have already entered.

For listed wastes, generators may be registering either a treated or untreated waste. Accordingly, you must list all of the regulated constituents with concentrations at or above the treatment requirements that are or were present in the waste before treatment.

For characteristic wastes, generators may be registering an untreated waste, a waste that has been treated to address only its hazardous characteristic, or a waste that has been treated to address both the hazardous characteristic and all other regulated constituents in Schedule 6. In all cases, you are required to list all of the regulated constituents with concentrations at or above the treatment requirements that are or were present in the waste before treatment, as well as the type of characteristic(s) that required treatment.

If wastes have been bulked, blended, or mixed before processing, the regulated constituents from all the incoming wastes must be identified for the resulting waste that is being shipped off-site - even if the bulking, blending or mixing process diluted any of the constituent concentrations below the treatment standard.

For all regulated constituents identified on the form you must identify which regulated constituents have been treated to meet the land disposal treatment requirement and which haven’t.

3.1.8.3 Variance from a treatment standard

Most generators will not need to complete this part of the LDR notification form, which must be completed only if the Ministry has issued a variance for a particular waste stream. An explanation is provided in the Variances section. Approval for a variance from a treatment standard may be provided through an ECA for the generator or receiver of the waste, through a Director’s letter of equivalent treatment, or through a regulatory exemption.

If the Ministry has granted a variance for the waste stream, the generator must identify the approval number for the variance that amended the treatment standard on the LDR notification form. If the variance is time-limited, the time limits of the variance must also be provided. Similarly, if an equivalent method of treatment has been approved, the approved treatment method must be identified. The generator should also check to ensure that the receiver has a copy of the variance.

3.1.8.4 Confirmation of treatment status

To identify the treatment status of the waste stream that will be shipped off-site, generators should choose the appropriate statement from the following list:

For characteristic wastes, choose one of the following:

waste has been fully treated to remove the hazardous characteristic and meets the underlying hazardous constituent (UHC) standards in Schedule 6
waste has been partially treated for the regulated constituents identified above and will be shipped off-site for further treatment
waste has been treated to remove the hazardous characteristic, but requires further treatment to meet the underlying hazardous constituent (UHC) standards in Schedule 6 for UHC(s) identified above
waste is being sent off-site to meet the land disposal treatment requirements for the regulated constituents identified above
waste is being shipped out of Ontario

For listed wastes, mixtures that include a listed waste, or waste derived from a listed waste, choose one of the following:

waste has been partially treated for the regulated constituents identified above and will be shipped off-site for further treatment
waste has been treated and meets the land disposal treatment requirements for regulated constituents identified above
waste has no regulated constituents present or all regulated constituents are already below the land disposal treatment requirements
waste is being sent off-site to meet the land disposal treatment requirements for the regulated constituents identified above
waste is being shipped out of Ontario

Although completion of the LDR notification form meets generator registration requirements for LDR wastes, the information on the form must be sent to the facility that will receive the waste, where notification is required for subject wastes (please see the Notification Requirements section for more information on LDR notification requirements).

3.2 Supplementary generator registration report

Should there be a change in the information in a GRR, a supplementary GRR needs to be submitted in accordance with S. 18(6) of Regulation 347. The supplemental registration report shall include the information needed to update the previously submitted GRR information, if that information is no longer correct or valid. Examples of a change include:

a change in company name, mailing address or telephone number
a change in the official responsible or main contact for the generator
the need to register additional waste streams
a change in waste characterization or waste class
a change in treatment requirements for LDR wastes
site closures (facility no longer generates or stores subject waste)

Please note that if you are relocating to a new site, you must register that site as a new facility (i.e., complete a new GRR for the new site). If the facility you are currently operating or for which you have recently ceased operations at is no longer generating subject waste that you are the operator for, this change in operations can be reported by deactivating the facility in the registry.

As a waste generator, it is your responsibility to complete and submit a supplementary GRR if any changes occur. This report must be completed within 15 days of the date the change took place.

3.3 Emergency generator registration

In the event of a spill or environmental emergency, please contact the Ministry’s Spills Action Centre (SAC) at 1-800-268-6060. SAC is staffed on a 24-hour basis to receive and record province wide reports of spills and to co-ordinate appropriate responses. SAC also provides a special emergency generator number (EGN) and a unique incident report number. All spills and environmental emergencies must be reported to SAC before an EGN can be issued. The EGN must be obtained from SAC before any subject waste can be removed from the site.

Once received, the EGN must be used in the Registry to complete a streamlined registration that is intended to facilitate quick access to manifests so as to not impede the removal of the contaminant as expediently as possible. A streamlined registration in the Registry must be completed before any subject waste can be removed from the site and each subsequent manifest in respect of that site related to the spill or environmental emergency must be entered into the Registry before that subject waste can be removed from the site.

3.3.1 Emergency generator registration information requirements

The information required to complete the streamlined EGN registration is as follows:

3.3.1.1 Legal company name and company operating name

You must register your company’s full legally registered name, as well as the company’s full operating name, if this is different from the legal name.

3.3.1.2 Waste generation activity

3.3.1.3 Emergency generator number (EGN)

The Registry requires that the generator provides an Emergency Generator Registration (EGR) number. This is the EGN that was provided by SAC.

3.3.1.4 Facility location

You must provide the waste generation facility’s (in this case, the spill or emergency location) full site address.

3.3.1.5 Mailing address

You must provide your company’s full mailing address (i.e., street name, number and postal code).

3.3.1.6 Primary hazardous waste contact

The primary hazardous waste contact is the individual who is responsible for managing or is responsible for staff that manages the hazardous waste and LIW at the spill or emergency. This person should be familiar with all the wastes for which they have management responsibility, should be able to answer technical questions relating to the facility and also be able to provide assistance in the event of an emergency.

3.3.1.7 Alternate contact

The generator may also identify an alternate contact who is also responsible for hazardous waste management at the facility.

3.3.1.8 North American Industry Classification System (NAICS) Codes

For a complete description of NAICS codes and further information, visit Statistics Canada’s website.

3.3.1.9 Waste class

Provide the waste class that you identified during your waste characterization and select the most appropriate waste type that describes your waste from a drop-down list. The Ontario waste class is a three-digit number (for example, 263, 121, etc.).

3.3.1.10 Primary characterization

3.3.1.11 Hazardous waste number

3.3.1.12 Waste number

The waste number consists of the three-digit number (Ontario waste class) plus a single letter (primary waste characterization), (for example, 263A, 121L, etc.).

3.3.1.13 Physical state

Describe the physical state of the waste stream (i.e., either solid, liquid or gas).

3.3.2 Completion of regular registration requirements after emergency generator registration

By enabling generators to obtain an EGN for the removal of subject waste that has resulted from a spill or environmental emergency, the Ministry recognizes that meeting the regular GRR requirements, including LDR requirements, may not be feasible in the immediate response to a spill or environmental emergency, particularly with respect to the characterization of the waste and treatment that may be required. However, once the immediate threat from the spill has been addressed, the owner of the waste is responsible for its complete characterization and for submitting a supplemental GRR to update the initial registration that was submitted as an emergency generator registration. This must include satisfying LDR requirements and all other registration requirements in section 3.1. The supplemental GRR must be submitted through the Registry within 90 days, as per subsection 18 (13) of Regulation 347.

Emergency generator registration is only intended to facilitate the immediate cleanup and removal of waste from a spill or environmental emergency, to protect public safety, remediate the situation and return the site back to its normal intended use as soon as possible. Emergency generator registration is not available for non-emergency situations such as process aberrations, upsets, one-time waste removals or other unusual circumstances that do not require immediate removal of the waste. In such situations, the registration process is available on a 24/7 basis through the Registry.

3.4 Responsibilities of the generator after registration

After registering successfully, a generator registration document for your facility will be posted on the Registry. The generator registration document contains your generator registration number and waste numbers, and you must use these numbers on manifests during all subsequent transactions involving subject wastes that are generated at your facility.

As a registered generator, you are responsible for ensuring that a generator registration document for your facility has been posted on the Registry, and that the information posted is correct. Please note that subject waste cannot be transferred until the generator has electronically submitted a GRR or the generator has been approved to use paper forms under section 27.1 and a generator registration document has been posted for that facility with the waste number for that subject waste.

Each waste generator is responsible for selecting accurate waste numbers. The waste numbers posted on the generation registration document for your facility should not be considered as confirmation of the accuracy of the information that you submitted during registration. If, due to new information or re-assessment of information submitted, you feel that your waste is incorrectly classified, you will need to revise your GRR by submitting a supplementary GRR.

3.4.1 Post-registration review

After your generator registration document has been posted on the Registry, your facility may be subject to a more detailed review of its waste management practices by the Ministry. The Ministry may conduct a detailed post-registration review that could result in requests for additional information or site visits.

It is also important to note that, as a waste generator, you are responsible for the characterization of your wastes and the information submitted on the generator registration report. The Ministry's review is only intended to assist you in this process. If your waste is found to be incorrectly characterized, or the information on your registration is incorrect even after your generator registration document has been posted, you could be liable for prosecution.

3.5 Information made available to the public

Section 6 of Ontario Regulation 323/22 requires the Registrar to post a generator registration document for each waste generation facility as soon as possible after a GRR for a facility is submitted through the Registry. The information available to the public is the following:

the date on which the Generator Registration Report was submitted through the Registry
the name of the generator, facility location, contact information for the generator and generator registration number
any waste numbers included in the report
