Five-Year Review Completed for Portions of the Site
August 2021
The EPA completed a Five-Year Review evaluating whether cleanup actions across several Operable Units remain protective of human health and the environment.
The review examined water management systems, residential soil remedies, and long-term monitoring programs.
Why this matters: Five-Year Reviews are a key checkpoint for long-term protection. Findings can lead to adjustments or improvements in cleanup systems.
Stormwater Pond Construction Underway
Ongoing
Construction has begun on additional stormwater ponds designed to capture and treat runoff before it enters Silver Bow Creek.
Temporary road changes and construction activity may occur near the work areas.
Why this matters: Stormwater management helps protect waterways and supports long-term recovery, while also creating new green space.
West Side Soils Investigation Continues
Ongoing
Sampling and monitoring activities are ongoing as part of the West Side Soils remedial investigation, including evaluation of soils, groundwater, and Blacktail Creek.
Why this matters: Investigation data help guide future cleanup decisions and ensure risks are understood before action is taken.
Greenway Trail Segments Continue to Open
Ongoing
Additional segments of the Silver Bow Creek Greenway Trail have been completed, extending the network of walking and biking paths along the restored creek corridor.
