In 2015, the U.S. Environmental Protection Agency (EPA) passed a new rule addressing the handling, storage and disposal of coal combustion residuals (CCRs). CCRs are the materials that remain after coal is burned.
The Clinch River Plant ash pond, known as Pond 1, is included in the program. However, this ash pond initially was not covered by the CCR rule. It was added to the program at a later date. Because of that, this facility has different compliance dates.
The ash pond has been closed and capped. Clinch River Plant ceased burning coal in 2015 and no longer produces CCR material. The Plant now uses natural gas as fuel.
- Coal Combustion Residuals Monitoring & Reporting
Appalachian Power Company (APCO) has begun the new groundwater monitoring program at Clinch River Plant.
APCO has installed 12 monitoring wells. It recently began the process of gathering the initial eight sample sets. The data from these samplings will establish baseline levels for 21 different substances in the groundwater at the ash storage site.
- Alternate Source Reviews
Independent third parties will conduct Alternate Source Reviews for the Clinch River ash pond. The review will consider other factors that could impact sampling results as the groundwater passes the CCR storage site. This work has not yet been completed for the ash pond because it was brought into the program at a later date and is on a different monitoring and compliance schedule.
- Location Restrictions
The CCR rule establishes location restrictions for coal ash storage sites. It requires that storage site locations be evaluated regarding proximity to
- The Groundwater aquifer,
- Fault areas,
- Seismic zones and
- Unstable areas (example: presence of quicksand).
The Clinch River ash pond is on a different compliance schedule and will be evaluated by April 2020. This pond has been closed.
- Next Steps
APCO continues to conduct groundwater monitoring and other activities as outlined in the rule.
