Byron Barrel & Drum
Byron Township, NY
No meeting scheduled.
The Byron Barrel and Drum site is located in Byron Township, Genesee County, NY, approximately nine miles north of Batavia, NY. The site occupies about two acres of an eight acre parcel, and was used as both a salvage yard for heavy construction equipment as well as a hazardous waste disposal site. The site contained approximately 400 drums of solid and liquid chemicals, reactive and flammable materials and polychlorinated biphenyls (PCBS). The site is bordered by heavily wooded areas and farmland, and is located within two miles of a residential area.
The site was proposed for the National Priorities list on October 1, 1984, and was included as final on June 1, 1986. Testing of residential wells near the site through 1994 did not detect any site-related contaminants.
In 1984, EPA removed drums, contaminated soils, and debris from the site, disposing of them at an EPA-approved hazardous waste disposal facility. EPA also sampled soils, tested nearby private wells, and installed a monitoring well.
In 1989, EPA completed remedial investigations and feasibility studies to determine the nature and extent of the contamination at and emanating from the site and to evaluate remedial alternatives. A Record of Decision (ROD) was subsequently signed, selecting a remedy for the site. The selected remedy featured extracting contaminated water by pumping vapors with activated carbon and the successive reinjection the treated ground water to flush contaminants from the subsurface soil in-place. To enhance the remediation of the contaminated soil in this area, an infiltration gallery consisting of perforated pipe and gravel was installed after the excavation of several feet of contaminated soil. The excavated soil was transported off-site for treatment and disposal. The infiltration gallery method was used in place of discharging the treated water to a recharge basin, which was originally planned in the Record of Decision, This modification to the remedy were documented in the August 2000 Explanation of Significant Difference. The in-situ soil flushing commenced in June 2000. The remediation of the contaminated soils was completed in September 2002. A ground water extraction, treatment, and reinjection system continues to operate at the site.
On September 24, 2002, EPA approved a Preliminary Close-Out Report, documenting the completion of construction activities at the site. Five year reviews are undertaken at sites to ensure that the implemented remedies protect public health and the environment and that they function as intended by site decision documents. EPA completed the first five-year review of the site in September 2007, and completed the second five-year review in September 2012. The reviews show that the implemented actions at the site continue to protect human health and the environment.
