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.

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.

Experts agree: Environment Minister Jonathan Wilkinson must designate Erin Waste Water Treatment Plant for Impact Assessment

Jack Imhof, an Aquatic Ecologist/Watershed Scientist, says “It is essential an independent federal assessment of the Erin Wastewater Treatment Plant be conducted in order to ensure the health of downstream communities and survival of the last healthy Brook Trout and Redside dace populations left in the Credit River watershed. This is NOT a “Fish or People” issue.” Jack Imhof has been involved in the study, assessment and management of the West Credit River since 1979, as well as the data collection and writing of the West Credit Subwatershed Study.

Media Release: Town of Erin pays only $2 for 5 Hectares of Prime Real Estate?

ERIN: Mayor Alls of Erin boasted, “I can reach in my pocket and pay for it” when the Town of Erin announced the purchase of 5 Hectares of land for $2 – land with an estimated value of $210,000 in the Environmental Study Report (ESR). 

Environmental lawyer David Donnelly spoke to the more than 300 people attending the March 25th virtual meeting to discuss the impact of the proposed Erin Wastewater Treatment Plant on dumping 7.2 million liters of sewage effluent daily into West Credit River Brook Trout habitat.
