Case Study: Sand & Gravel Mine Permitting Support

Client: Various Location: Multiple sites in WA Contact for water resource projects: Tim Flynn

Project Background & Challenges

Because of many recent water-resource policy changes, developing environmentally responsible gravel mines is challenging — particularly in growing suburban areas where gravel is needed most. The design and permitting processes must address how to protect water resources, secure rights for water usage, and mitigate impacts via engineered stormwater systems. They must also incorporate appropriate monitoring programs, because mines typically occur in areas where aquifers receive recharge, provide drinking water supplies, and feed stream baseflow.

Solution

Aspect works hard to provide feasible, cost-effective solutions that are consistent with the mining business needs. We have developed strategies to not only address these problems but also to enhance fisheries. In addition to characterizing water resources, our solutions involve designing grading and drainage systems, water quality treatment systems, infiltration facilities, and performance-based monitoring programs. Currently, we are providing support for EIS processes, grading permits, NPDES, and water-rights permitting at several mining sites.
