We invite you to review and comment on the draft periodic review report, which includes the results of our site condition review to ensure cleanup is still protective.
The site was built in 1915 to burn coal and produce steam and electric power. In the mid-1960s, the boilers were converted to use petroleum (Bunker C). Petroleum for the boilers spilled in 1982. Investigations found petroleum in soil and shallow groundwater.
Cleanup included excavating contaminated soil near the ground surface and replacing it with clean soil, capping the area with asphalt, and removing the underground storage tanks. Groundwater monitoring is ongoing, and petroleum is removed from groundwater through extraction wells. A restrictive covenant is on the property, prohibiting the use of groundwater and any activities that would expose remaining contaminated soil.
We visited the site on February 8, 2023, and found the cleanup actions continue to protect people and the environment.
We will review all comments received during the comment period and will update the periodic review, if needed. If no significant changes are made, the periodic review will become final. If significant changes are made, we will hold an additional public comment period. We will hold an online public meeting if 10 or more people request one.
About periodic reviews
We complete a periodic review at least every five years after cleanup construction is complete at any site where institutional controls are part of the cleanup. This is the third periodic review for this site. The purpose of the review is to evaluate site conditions to ensure people and the environment are protected.
