Decision details
A new Environmental Compliance Approval (ECA) was issued to Cornwall Gravel Company Limited for approval of:
- upgrades to the existing works for the collection, transmission, treatment and disposal of up to 15,305 litres/min of water (including precipitation, stormwater runoff, snowmelt, groundwater and aggregate wash water) accumulating within the confines of an approximately 68.8 ha extraction area of the existing Cornwall Gravel Greely Quarry, discharging to the Mutual Agreement Drain and ultimately via the Cassidy Drain to the Middle Castor River
- existing works for the collection, transmission, treatment and reuse of wash water from existing aggregate washing operations located within the existing Cornwall Gravel Greely Quarry site, located in the City of Ottawa
The new ECA approved an increase of the previously approved discharge rate from the upgraded dewatering sump from 7,500 litres/min to 15,305 litres/min to align the ECA discharge limit with the new Permit to Take Water No. 6385-CB9MAF, issued on February 9, 2022.
The approved works consist of:
- one expanded irregularly shaped dewatering sump located in the eastern corner of the extraction area, across John Quinn Road, and
- one new outlet structure from the dewatering sump consisting of the following:
- one appropriately sized for a maximum size of discharge piping maintenance hole
- one 3 m long 575 mm diameter outlet pipe
- one 375 m long, 2.5 m based wide and 0.85 m deep grassed trapezoidal outlet channel located along the eastern site boundary, between approximately 30 m to 40 m from the eastern site boundary, having a bottom grade of 0.5% and 3H:1V side slopes
- one 42 m long, 575 mm diameter outlet pipe located in the eastern corner of the site, discharging via the existing drainage ditch located along the southern site boundary and the existing 1,400 mm diameter CSP culvert located under John Quinn Road to the Mutual Agreement Drain and ultimately via the Cassidy Drain to the Middle Castor River

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

- 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

- 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

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

Original proposal
Proposal details
This proposal is to amend the existing Environmental Compliance Approval No. 4013-9C5P89, issued for the approval of sewage works at the Greely Quarry, located at 7695 Stone School Road in Osgoode, Ontario.
The sewage works that were previously approved are composed of:
- One irregular shaped pumping sump, measuring approximately 34 metre x 50 metre x 10 metre deep equipped with a submersible pump at up to 7,500 litres per minute, discharging to a settling/impoundment pond.
- One closed-loop aggregate wash system that uses water from the sump to wash aggregate and returns wash water through a series of settling ponds, check dams and gravel filters to the sump.
- One settling pond (Inactive Campeau Quarry) with a total effective volume of approximately 76,600 cubic metres, discharging via a vegetated ditch extending to the Mutual Agreement Drain.
- One buried concrete storm pipe for the sump discharge that is 100 metres long, has a diameter of 400 millimetres and is connected to a downgradient pipe.
- One buried concrete pipe that is 250 metres long and has a diameter of 1200 millimetres.
The proposed amendments are:
- One irregular shaped pumping sump (east-west orientation) with a footprint of 1,830 square metres and a settling depth of 8.05 m. Total volume of 14,731.5 cubic metres. It will include an extension of the sump to the north with a footprint of 540 square metres and a settling depth pf 8.0 metres, for a volume of 4,320 cubic metres. The sump is equipped with a submersible pump at up to 15,305 litres per minute to align with the new amended PTTW limit.
- One closed-loop aggregate wash system that uses water from the sump to wash aggregate and returns wash water through a series of settling ponds, check dams and gravel filters to the sump. The trenches within the eastern area of the existing quarry have a footprint of 6,146 cubic metres and 4,600 cubic metres.
- One maintenance hole and one storm pipe. The sump discharges to a maintenance hole and then into the storm pipe of 3 m long, with a diameter of minimum 575 millimetres, and will discharge into an open channel.
- One open channel approximately 357 metres long, 2.5 metres wide and 0.85 metres deep, along inside of eastern berm of the quarry property (along John Quinn Road). The open channel discharges into the storm pipe.
- One buried storm pipe of approximately 42 metres long and a diameter of minimum 575 millimetres, which will go under the southern berm of the quarry property (along Stone School Road) and discharge into the drainage channel along the southern boundary of the quarry property.
