Embro Dam Class Environmental Assessment – Alternatives

There are very few thriving Brook Trout populations left in southern Ontario, and it is especially surprising to find them present as far south as London, Ontario. Brook Trout are a sentinel species – the canary in the coal mine. In southern Ontario, Brook Trout populations have seen an 80% decline in their numbers over the last 50 years. Their populations have been under increasing pressure from a warming climate as well as agricultural, urban, rural and industrial development.
Removing the Dam and headpond to create a free-flowing and healthy coldwater Brook Trout fishery would be the perfect place for a family to go for walk, play or picnic in the Embro Conservation Area. It would provide a healthy riverine ecosystem and a beautiful natural environment for the entire community to enjoy!!
Mill Creek Weir Removal Project

The ORA is pleased to partner with Credit Valley Conservation (CVC) in the Mill Creek Weir Removal Project. Mill Creek is home to an at-risk population of native Brook Trout, and the weir is a barrier to fish passage and prime habitat. Mill Creek is the lowest dam before its confluence with the Credit River.
The concrete weir is broken and cracked, and if individuals from the Brook Trout population were to breach the weir, they could be permanently trapped in a small pool on the other side, with no way back. Removing the weir will remove this hazard, open up 5 km of uninterrupted Brook Trout habitat, and increase Mill Creek’s resilience to a warming climate. The ORA applied for and received a $5,000 Lush grant towards the new detailed channel design. Continue reading
Environmental Compliance Approval Number 7877-CALRZU – Erin Water Resource Recovery Facility – Joint

First, the Coalition for the West Credit River (Coalition) would like to express our deepest appreciation that you and your staff worked with our Technical Team over the last several months to incorporate some of our recommendations into the Environmental Compliance Approval (ECA). However, we are concerned that our key recommendations for improvements to the draft ECA, received by you on 2 May, were not reflected in the ECA approved on 3 May 2022.
Delegation Request – Erin Water Resource Recovery Facility – Joint

The Coalition is very appreciative of your strong support in recommending to the Honourable David Piccini, Minister of Environment, Conservation Parks (MECP) and Mayor Allan Alls, Town of Erin, that our draft Monitoring and Adaptive Management Plan be integrated into the Environmental Compliance Approval (ECA). As you are likely aware, the ECA for the Erin Water Resource Recovery Facility was approved on 3 May 2022 by Aziz Ahmed, P.Eng., MECP Manager of Municipal Water & Wastewater Permissions, appointed for the purposes of Part II.1 of the Environmental Protection Act.
Inground Infiltration of Wastewater
In consideration of the ecosystem benefits of a healthy West Credit River and its sensitive Brook Trout and Redside Dace population, we are recommending that inground infiltration of the final wastewater effluent be seriously considered, as a viable alternative to discharging warm sewage effluent directly into the West Credit River. Discharge of treated effluent by way of passive infiltration into the ground with slow percolation into this relatively small stream is the best way to ensure that the final effluent reaches the stream as natural and cold groundwater.
Media Release: Erin Wastewater Treatment Plant – Federal Review Denied

Judy Mabee, Chair of the Coalition and President of the Belfountain Community Organization stated that, “The Coalition is not deterred by the Minister’s Decision. We will continue on with our work to protect this highly valued coldwater Brook Trout population in the West Credit River. We are more than willing to work with the Department of Fisheries and Oceans and other federal and provincial regulators, including the Town of Erin and its consultants, to advocate for a wastewater plant that sets a new best in class industry standard for the protection of sensitive coldwater receiving streams.”
Minister Wilkinson Decision on Designation Request – Letter to Coalition
After careful consideration of the information provided by the Town of Erin, federal authorities, provincial ministries, the local conservation authority, the concerns expressed in your letter, other known public concerns, and advice from the Impact Assessment Agency of Canada (the Agency), I decided that the Project does not warrant designation pursuant to Subsection 9(1) of the IAA.
Proposed Erin Wastewater Treatment Plant – Follow-up Commitments to the Environmental Study Report
The Coalition has carefully reviewed the ESR to see what habitat related to endangered or threatened species, Schedule 1 SARA species, migratory birds or rare and uncommon plants may have been impacted by significant damage that was done on the Solmar property in late December 2020 and into the first quarter of 2021. In particular, the damage related to the premature removal of brush and trees in and around the Project site, as well as significant damage to a first order tributary to the West Credit River in a Provincially Significant Wetland and Greenlands Natural Heritage designated area (Addendum 2). The Coalition has ascertained that there were no permits or authorizations for any of this work to take place. It is very difficult to do additional bird and tree studies when a great number of the trees and habitat were removed and burned.
Erin WWTP – Concerns over Brook Trout and Fish Habitat on the West Credit River

Redds just below culvert.
To confirm our position that the habitat within the culvert is not degraded and supports Brook Trout throughout the year, we draw your attention to a video by Steven Noakes, a local videographer, entitled, Brook Trout fry at proposed outfall location Erin WWTP, taken on the 30th of April 2021 in and around the culvert at the proposed effluent discharge site. The video confirms that Brook Trout fry are abundant in and around the culvert and demonstrates that the culvert habitat is not degraded, removing any question that it supports Brook Trout. In addition, Brook Trout spawning activity occurs a short distance above and below the culvert, where redds are abundant within 75 to 100m of it. There is no question that this area supports Brook Trout in various life stages.
