Détails de la décision
Approval was granted to the Ontario Power Generation Inc. (OPG) Darlington Nuclear Generating Station (DNGS) to amend existing ECA (industrial sewage) No. 0827-CJANMM to reflect the proposed plan to construct, commission, operate and maintain a new Darlington Nuclear (DN) Demineralized Water Plant (DWP). Approval was granted to OPG to initiate a new DWP project to replace the existing aging water treatment plant (WTP) to continue supply of demineralized water for DNGS.
A highly reliable supply of demineralized water utilizing current proven technologies is required to support station operation on a continuous basis 24 hours per day, 7 days per week, 365 days per year beyond the end of Darlington station life (estimated in 2055). The existing WTP has been in service since 1987, however, it has come to its design end of life.
In addition, the existing WTP is required to be in operation during commissioning of the new DWP. As such, there will be a period for about 12 months when both facilities are required to be operated at the same time.
The OPG new DWP facility will have a capacity to generate a maximum flow of 120 L/s [10,368 m3/d] high purity demineralized water, with an annual average water demand of about 45 L/s [3,888 m3/d].
The WTP is located outside of the protected area and will replace the existing WTP. The proposed location of the new DWP facility is east of the DN Station.
Approval was granted for basic processes to include pre-treatment, ultrafiltration for suspended solids removal, reverse osmosis for dissolved solids removal, granular activated carbon for removal of chlorine and chlorinated hydrocarbons, and continuous electrode ionization for residual ion removal, followed by final mixed bed ion polishing.
The main liquid waste effluent stream, originating from ultrafiltration maintenance wash/cleaning and reverse osmosis cleaning/concentrate waste, is to be discharged to Condenser Cooling Water (CCW) duct from the new DWP after neutralization, chemistry control, and verification at an estimated maximum flowrate of 51.4 L/s [4,440.96 m3/d]. Monitoring and sampling are to be conducted prior to discharge to the CCW duct discharge line, which leads to Lake Ontario.
In addition, approval was granted for a a new stormwater management pond and an oil/grit separator will be installed between the outlet at the pond and the outfall at the ditch to accommodate the post development site hydrological conditions of the new DWP building, prior to ultimately discharging to Lake Ontario.

Start the process to appeal
If you’re an Ontario resident, you can start the process to appeal this instrument decision.
First, you’ll need to seek leave (i.e. get permission) from the relevant appellate body to appeal the decision.
If the appellate body grants leave, the appeal itself will follow.
Seek leave to appeal
To seek leave to appeal, you need to do these three things:
- prepare your application
- provide notice to the minister
- mail your application to three parties
1. Prepare your application
You’ll need to prepare an application. You may wish to include the following things in your application:
- A document that includes:
- your name, phone number, fax number (if any), and/or email address
- the ERO number and ministry reference number (located on this page)
- a statement about whether you are a resident in Ontario
- your interest in the decision, and any facts you want taken into account in deciding whether you have an interest in the decision
- the parts of the instrument that you’re challenging
- whether the decision could result in significant harm to the environment
- the reason(s) why you believe that no reasonable person – having regard to the relevant law and to any government policies developed to guide decisions of that kind – could have made the decision
- the grounds (facts) you’ll be using to appeal
- the outcome you’d like to see
- A copy of the instrument (approval, permit, order) that you you are seeking leave to appeal. You’ll find this in the decision notice on the Environmental Registry
- Copies of all supporting documents, facts and evidence that you’ll be using to appeal
What is considered
The appeal body will consider the following two questions in deciding whether to grant you leave to appeal:
- is there is good reason to believe that no reasonable person, with respect to the relevant law and to any government policies developed to guide decisions of that kind, could have made the decision?
- could the decision you wish to appeal result in significant harm to the environment?
2. Provide your notice
You’ll need to provide notice to the Minister of the Environment, Conservation and Parks that you’re seeking leave to appeal.
In your notice, please include a brief description of the:
- decision that you wish to appeal
- grounds for granting leave to appeal
You can provide notice by email at minister.mecp@ontario.ca or by mail at:
College Park 5th Floor, 777 Bay St.
Toronto, ON
M7A 2J3
3. Mail your application
You’ll need to mail your application that you prepared in step #1 to each of these three parties:
- appellate body
- issuing authority (the ministry official who issued the instrument)
- proponent (the company or individual to whom the instrument was issued)
