Purest Water Alert: Ontario government grants CRH permit to take water at Teedon Pit
Posted on the Environmental Registry of Ontario

Over 5,000 comments were received. The decision details what the government considers to be the major concerns raised by “stakeholders” and why it has decided they can be disregarded. There is a 15-day appeal period. The decision is reproduced below.

Here’s the decision posted January 15 2021:
We issued Permit to Take Water No. 6258-BRDJ2M to CRH Canada Group Inc. on January 14, 2021. The Permit is a renewal of CRH Canada’s previous Permit, and will expire on January 13, 2031. This Permit allows water taking from one pond and one well for aggregate washing purposes at Teedon Pit, at rates similar to previous Permits.
Details are as follows:
Permit Type – renewal – Category 3
Sources of water for aggregate washing:
maximum rate per minute (Litres): 950
maximum number of hours of taking per day: 24
maximum volume per day (Litres): 1,368,000
maximum number of days of taking per year: 210
maximum rate per minute (Litres): 7,274
maximum number of hours of taking per day: 12
maximum volume per day (Litres): 5,237,280
maximum number of days of taking per year: 210
At the Teedon Pit, water from the on-site pond (referred to as a Wash Pond) is used for washing the aggregate, and separating silt and sand from coarser material. The water that is used is sent to two settling ponds where the silt and sand settle to the bottom. Water from the settling ponds is directed back to the Wash Pond for reuse. The water level within the Wash Pond is topped up as needed from the on-site Production Well (Well PW 1-09).
Surface water bodies in the area include Hogg Creek, Wye River, the Tiny Marsh (a Provincially Significant Wetland) and the Tiny Bog Wetland Complex (a regionally and locally significant wetland). These water bodies are located at significant distances from Teedon Pit. Therefore, they will not be affected by the water taking from the Wash Pond or from Well PW1-09.
An unnamed stream connected to a small pond, which only flows during snow melt in the spring or periods of extremely heavy rain, is located on the northern property boundary. Water taking/usage at the Teedon Pit is unlikely to adversely impact this unnamed stream.
Water taking at the Teedon Pit is located far from any municipal water supply well. It will not have any impact on any municipal water supply well. Municipal wells in the area are:
Elmvale (Wells 1 & 2),
Perkinsfield (Wells 26-4 & 26-5), and
Wyevale (Well 29-1 & 29-2).
The closest municipal well to the Teedon Pit is Wyevale, which is approximately 5 km to the northwest of the site. The Teedon Pit is also outside the Wellhead Protection Areas (WHPAs) associated with these wells.
The ministry is satisfied that the water taking at Teedon Pit does not interfere with private water supply wells located in the area. This conclusion is based on the review of monitoring data provided in support of the renewal application, and records of investigations of past well interference complaints by well-owners in the area. Past investigations identified that the interference complaints were not related to operations at Teedon Pit. To ensure water supply wells are protected, the renewal Permit has been issued with conditions requiring continued monitoring of water levels at several monitoring locations.

133 submissions were received on-line and an additional 5,113 comments by e-mail (of which 5,092 were identical).
Comments relevant to the water taking proposal were considered as part of the review of the application. The main concerns raised were regarding the following:
-There were comments that the volume of water proposed to be taken from the groundwater system is unsustainable and could result in sinkholes. The ministry’s review has determined that the taking is sustainable and will not result in sinkholes.
-A concern was expressed on the impact of the washing operations on the aquifer and the introduction of dirty water into the aquifer. Teedon Pit will only use water with no additives in their washing process. The silt and sand contained in the used wash water settles to the bottom of the settling ponds. Any water that infiltrates into the ground at the bottom of the ponds is filtered, much like rain water. Therefore, the ministry is satisfied that the operation is unlikely to adversely impact the groundwater quality.
-Stakeholders are concerned about the impact of the water taking and aggregate washing on the local aquifers and the Alliston Aquifer. The ministry’s review has determined that monitoring undertaken by past and current permit holders demonstrates that that there is no long-term impact on groundwater levels in the production well, the monitoring wells, or the monitored domestic wells. The amount of water used in aggregate washing has no visible impact on groundwater levels.
-A concern was expressed regarding the impact of the operations on local wells. As explained above, the ministry’s review has concluded that the water taking does not have adverse impact on local wells.
-Stakeholders have requested a cumulative impact study be completed to determine the short and long term impacts of the overall pit operations. Based on the ministry’s review of the data acquired to date and the analysis completed during the review of this application, the water taking at Teedon Pit is unlikely to have any measurable impact on the aquifer outside of the 350 m radius around the Production Well.
