Aggregate Facilities

Aggregate Extraction Projects (gravel pits) present unique challenges for noise modeling, noise monitoring and impact assessments. In particular, the noise sources are rarely stationary and often vary between operational stages and phases.  Each of which affects the noise produced.  In addition, due to the current demands of aggregate within Western Canada, these facilities are being pushed further and further into remote areas with little to no existing industrial presence. 


Within the past 15 years ACI has worked on more than 100 Aggregate related noise projects ranging from large permanent plants run by international corporations to small gravel pits run by local entrepreneurs. Despite their differences, the ultimate goal of each project is to mitigate the acoustical impacts on local residents.


ACI has a vast library of Aggregate Facility related noise sources ranging from earth movers to rock crushers and wash plants to haul trucks. ACI is well versed in the acoustical requirements set forth in noise regulations such as the Alberta Energy Regulator (AER) Directive 038 and other local bylaws within many of Alberta's municipal districts (e.g. Parkland County, County of Lac St. Anne, Rocky View County, Red Deer County, etc.)


In addition to noise impact assessments, ACI has the equipment and expertise to conduct long term noise (and Dust) monitorings from several days up to several months and even permanent installations.
