Noise Impact Assessment
West Can Seal Coating Gravel Pit LSD 8-35-32-6 W5M
West of Sundre
Objective of the Assessment Assess the sound data of typical equipment and
operations that are proposed for the West Can Seal Coating Gravel Pit.
Predict the noise level from exploration phases, during the Stripping stage, the Crushing, Washing, Asphalt production, and Transportation operation phase at the potentially most affected receiver locations.

Conclusion
The Predicted Sound Level for stripping phase (without berms) exceeds the Permissible Sound Level (55dBA Daytime) at nearest Receiver to the respective phase of operation.
The Predicted Sound Level for the Crushing, Washing & Asphalt production phase (without berms) are within the Permissible Sound Level (55 dBA Daytime) at all Receivers around proposed gravel pit except Receiver 1 and Residence 8.
The predict Sound Level at Receiver 1 & 8 exceed the PSL due primarily to the hauling of product from the site.
The introduction of 3m and 5m high berms brings down the predicted sound level below the PSL during the Striping phase except phase 3 and Phase 4.
In the Crushing, Washing & Asphalt Production phase, berms bring down the predicted sound level at all Receivers except Residence 1 and 8.
Noise levels at Receiver 8 are due almost exclusively to the transportation of product on the adjacent road
