Colacem is committed to working with the community in an open and collaborative manner. Colacem will establish a Community Liaison Committee (CLC) for the Project, to provide a venue for representatives of Colacem, the local government and the community to meet regularly and learn about the status of the Project and address any concerns or questions, such as the ones that follow:

Who is Colacem Canada?

Colacem Canada is one of the most recent companies acquired by Uniroc Group, a leader in road infrastructure and civil engineering. The Uniroc Group is the result of a partnership between two Canadian pioneer families that came together in 2012. The Uniroc Group works mainly in the fields of paving and concrete.

Why do we need another cement plant in Ontario?

The proposed cement plant will increase the Canadian cement production capacities thus reducing imports. Beside supplying cement to the Canadian Market, it will also serve the American market.

How will this Project benefit the community?

The proposed plant is a significant investment in the community, with the capital costs to construct the project estimated at $225 million.  Once in operation, the local purchases are estimated to be $5 to 6 million annually. 

What will the employment benefits of the Project be?

During construction it is estimated that the Project will employ 200 people over a two year period.  During operations it is estimated that the Project will create 125 direct employment opportunities and 175 indirect employment opportunities.

How much cement will the plant produce?

The cement plant will have an estimated capacity to produce 1.16 million tonnes of cement a year.

What are the key components of the cement plant?

The cement plant will utilize the most advanced production technology available to achieve efficient energy consumption and minimize impact on surrounding ecosystems.   This state of the art technology includes a hybrid air filter to provide reliable dust control, energy generation from excess heat, and zero wastewater discharges to the environment.  The facility will be comprised of structures including material storage, hoppers, conveyors, crushing and grinding systems, raw mill, preheater, rotary kiln, cooler and cooling tower, a 125 m. kiln stack, cement mill, and administrative offices.

What fuel will be used?

The facility will use petcoke to fuel the plant.  Petroleum coke (petcoke) is a solid carbon product that is produced in the oil refining process and commonly used world-wide as an efficient fuel for industrial applications.

What permits are Colacem required to get for the Project?

Colacem is seeking approval to build and operate the proposed cement plant through two regulatory processes: the Planning Act approvals process and the Environmental Compliance Approval process. In order to obtain this permits the company provided a list of technical studies to be found on the download area of this website.

How much truck traffic will be generated by the Project?

The additional regular traffic generated by the proposed plant will represent approximately 1% of the road design capacity. Please refer to the page Traffic and Road Safety

Will excessive emission be generated by the plant? 

No, the new plant will be significantly below standard established by provincial and federal lows. Colacem will be controlling emission at the plant using a state of the art “hybrid” electrostatic precipitator and baghouse filter to provide the best overall efficiency.

How can the public access the emissions data from the plant?

Emissions data from the proposed cement plant will be publically available throughout the life of the project.  Currently, the ESDM report is available on the project website.  The ESDM report will be updated periodically as the project proceeds; for each revision to the ESDM report, the updated Executive Summary and table of emissions data will be publically available in accordance with O. Reg. 419/05.  In addition, annual emission data will be publically available as part of the federal reporting program (National Pollutant Release Inventory) and provincial program (Toxics Reduction Act (O.Reg 455/09)).  CO2 emissions will also be reported in accordance with the Ontario Greenhouse Gas Reporting Regulation 452/09).

Will excessive noise be generated by the plant?

Colacem will use silencers on equipment and acoustical shielding, such as locating other buildings and/or berms between noise sources and neighboring receptors, where necessary, to reduce noise levels for its neighbors and staff.  Where possible, the distance between receptors and significant noise sources will be maximized.

Will the plant cause vibrations in the ground?

Every human activity produces some kind of vibration (eg. road traffic).  Vibrations produced by cement plants  are unperceivable by a human being  just  a few meters away,  and are inconsequential outside the factory area.  


Will operations at the quarry change?

The overall management of the quarry shall be reviewed and improved. All material destined to the cement plant (i.e. 70‐80% of the total) shall be crushed in a modern fixed crusher, that shall be dust exhausted and soundproofed using the best available technology; use of the current mobile crushers, which are more difficult to manage, shall be reduced to the minimum possible degree.
Furthermore, the new plant shall be able to work with larger sized limestone, thus leading to minor use of
explosives even in presence of major volumes.

Will excessive light be generated by the plant?

Illumination shall be such as to guarantee adequate safety conditions for operators at the cement plant.  Generally speaking, illumination shall be inside the various buildings and will be activated only when personnel are present. External areas shall be provided with screens to convey light downwards, towards the interested areas (i.e. there shall be no beams of light directed towards the sky).

Will there be any impacts to groundwater?

Water to operate the cement plant will be obtained from the existing quarry sumps.  There will be no process water discharge to the environment; stormwater from the site will be collected and treated.
There will no changes/impacts to the local groundwater conditions. 

The courts have recently admitted to trial a class action law suit against the Kilmar Plant. Can you describe how this lawsuit came about and what are key points to consider for L’Orignal residents?

The issue was settled by the previous owner of Colacem Canada before court

Will property values be devalued by the cement plant?

The cement plant will open a whole range of new economic opportunities and new employment for the community, which may increase property values.

The regulatory approval processes also include numerous opportunities for public involvement, including
attending a public open house, participating at municipal council meetings, and submitting comments on the
approval applications to the regulatory agencies directly.
