CBM Aggregates’ Shelter Valley Plant Receives OSSGA Rehabilitation Award

CBM Aggregates’ Shelter Valley Pit in the Township of Alnwick/Haldimand, Ontario, Canada, received the Ontario Stone, Sand & Gravel Association’s (OSSGA) 2021 Progressive Rehabilitation Award, presented at OSSGA’s 2022 Conference and annual general meeting at the end of February.

Shelter Valley Pit earned its first Progressive Rehabilitation Award for its success in transforming the extraction faces around its east and south perimeter and a portion of the floor into a naturalized forested area. 

The rehabilitation targeted 3.05 hectares of land and was completed in fall 2019. It required the placement of 3,000 cu. meters of overburden to obtain a 3:1 slope at the east face and grading the pit floor with 2,500 cu. meters of overburden. 

The slopes and floors were covered with 6 to 8 in. of topsoil, and the site was seeded with a mix of native grasses such as big bluestem, little bluestem, poverty oat grass, forbes butterfly milkweed and hoary vervain. In May 2021, 500 trees were also planted by the Northumberland Tree Planters.

“We are very pleased to receive the OSSGA Industry Recognition Awards for Progressive Rehabilitation and Property Enhancement,” said David Hanratty, director of land & resources, North America. “CBM Aggregates strives to achieve excellence in all aspects of our operations and we are so appreciative of the recognition from OSSGA in these two categories.”
