South Excavation and Asphalt Plant
1. Where is the south gravel site located?
The south gravel site is located in the Transportation Utility Corridor (TUC) north of Highway 22X, between 37 Street and the community of Bridlewood.
2. Why was this site selected for the gravel operation?
- As part of the construction for the SWCRR an excavation is required for the interchange at 162 Avenue and for the future stormwater ponds.
- With the discovery of gravel in the area, the decision was made to process this resource at a nearby site.
- Much like the north site, the proximity of the resource reduces costs for the SWCRR and improves safety by reducing haul distances and removing trucks from public roads.
3. When did you decide to use the south gravel site?
- The south gravel site was subject to geotechnical investigations in late 2016 and early 2017 to determine the nature and volume of gravel in the area.
- A decision was made to proceed with a gravel operation in early 2017.
- The excavation is required in order to excavate the stormwater ponds being planned for the area around the 162 Avenue interchange.
4. What are the noise level restrictions?
- Construction activities are subject to a noise level restriction set by the Province of an average 65 decibels over a 24-hour period.
5. What are the operating hours?
- The project hours for the construction of the SWCRR are Monday to Friday from 7:00 a.m. to 10:00 p.m. and Sundays and holidays from 9:00 a.m. to 10:00 p.m.
6. How are you addressing concerns regarding dust?
- A 10 to 30-metre buffer zone was left between the community and excavation.
- Regular dust mitigation activities include watering and application of dust palliatives.
- The crushing equipment makes use of a water system on material transfer points.
- The crushing operations are located more than 400 metres away from the community and they are screened by stockpiles to help limit dust.
- Dust monitoring equipment has been installed on the site and all provincial and project thresholds are being observed.
7. Why won’t a berm be built along the community of Bridlewood?
- There is a gas line that runs along the community of Bridlewood, which prevents the construction of a berm in this area.
8. Where is the asphalt plant located?
- The asphalt plant is located immediately north of Highway 22X.
- It is over 700 metres away from the community at the further possible distance while still inside the TUC.
9. How are odours from the plant controlled?
- The asphalt processing plant follows all regulatory requirements, including the Province’s Code of Practice for Asphalt Paving Plants.
- The plant runs on natural gas, rather than traditional bunker fuel oil, to further reduce any odours.
- The plant makes use of emission control technology to limit odours.
10. When are operations expected to conclude at this site?
- Gravel crushing operations are expected to conclude at the south excavation in 2019.
- Road construction and operation of the asphalt plant will continue into 2021.
