Regarding: ERO #019-2876, “Project-specific proposal to designate and exempt the proposed Reid Road Reservoir Quarry (“Quarry”) in Milton under the Environmental Assessment Act.”

As a citizen concerned about the impact on the health and safety of the proposed Quarry on the community, the development of a comprehensive Terms of Reference is imperative to properly direct the assessment. Defining the Terms of Reference must be open, transparent, and allow the full participation of the public, as well as key stakeholders including ACTION Milton.

Below, I provide a list of issues of particular concern to me. Although many details of these issues have been addressed by the proponent’s consultants and have been reviewed in great detail by the JART organizations and their consultants, I remain concerned that the review has not adequately addressed all my concerns.

Underwater blasting
• I am concerned that blasts detonated adjacent to and below the bottom of the pond, could cause irrecoverable damage to the groundwater supplying private and municipal wells. The groundwater flows slowly meaning that we might not see the impact of the blasting on our wells for several years making it easier for the proponent to deny liability for any future reduction in the quality and/or quantitfy of water supplying both private and municipal wells.

Flyrock
• The potential for flyrock on the 401 does not seem to have been studied adequately. Our understanding is that because the blast takes place adjacent to a pond, risk of flyrock is deemed to be inconsequential. This does not make sense. There are vertical forces as seen when blast mats lift on detonation of a charge; these forces are not 100% controllable and flyrock can be the result. As well, there is exposed vertical rock above the pond water level which is not at all mitigated by the presence of the water.
• The proponent stated that flyrock will not occur because it is not allowed. This is condescending at best and reinforces the need for additional study.

Traffic/Road Safety
• The impact on 401 traffic was not part of the scope of studies done to-date. This is unacceptable. Big fully loaded gravel trucks entering and leaving the 401 will disrupt traffic flow on the 401. A full highway corridor management study needs to be conducted.
• During times of highway congestion, it seems obvious that the gravel trucks will travel on municipal roads. The impact of these trucks travelling through the community has not been adequately studied.

Air Quality
• Fine particulate matter (PM2.5) is a known hazard and greater exposure increases risk. This risk to public health of the additive impact of this invisible dust has not been quantified or studied adequately. Natural Environment
• It is difficult for me to understand how the value of the site’s Provincially Significant Wetlands is being protected. Simply managing water level (if indeed that is achievable) will not protect against the incessant dust, blasting, noise and truck traffic on this important ecosystem.

• The Province states that the value of wetlands includes:
o groundwater storage and release
o provision of habitat for wildlife species, including species at risk
o ecosystem productivity and biological diversity
o flood damage prevention
o harvestable product provision
o improved water quality
o recreational opportunities

• A study needs to be undertaken to determine whether the licensing of this quarry would be consistent with the stated value of these important wetlands which are rated as being Provincially Significant.

Noise
• Along with the blasting vibration, noise would be incessant from the extraction and crushing of rock and the acceleration/deceleration of gravel trucks 6 days per week.

Recycling/Reprocessing Asphalt & Concrete
• Permitting the stockpiling of used asphalt and concrete on the site and the reprocessing of them is a source of potential contamination which I understand has not been adequately studied. Definition of Environment
• Additional areas of concern which were not raised as part of the study include the “social, economic and cultural conditions that influence the life of humans or a community”
• As noted in the ERO posting, over 1000 letters of objection were received by the MNRF. If the EA is conducted, each of these letters needs to be reviewed by the MECP to gain further insight into and to address both the technical and overall societal concerns of the community.

It simply does not make sense to license a quarry so close to the community, adjacent to Provincially Significant Wetlands and beside a 400-series highway.

While I appreciate the work that has been done to-date by the local governments, I remain concerned that there are gaps in the studies which present significant risk to the community.
