ENVIRONMENTAL CLEAN-UP PROJECT


Update


The completion of the environmental clean-up at the site of the future Denny Substation in early 2014 marked an important milestone for the project. The soil and groundwater of the former Greyhound Bus Maintenance Facility were contaminated with gasoline, diesel and waste oil and needed to be cleaned up prior to constructing the substation. Site clean-up involved demolishing the maintenance facility, removing underground storage tanks, removing contaminated soils, installing a storm water detention system and backfilling the site with clean dirt. The site is now ready for construction; however, the environmental review and design of the substation need to be completed before construction begins.
