Hazardous Waste Cleanup: Seneca Landfill (Formerly: Vogel Disposal Service) in Harmony, Pennsylvania

On this page:


Cleanup Status

EPA sets national goals to measure progress toward meeting the nation’s major environmental goals.  For Corrective Action, EPA evaluates two key environmental indicators for each facility: (1) current human exposures under control and (2) migration of contaminated groundwater under control.  In September 2002, EPA determined, with Pennsylvania Department of Environmental Protection (PADEP) input, that both the Human Exposures and Groundwater Environmental Indicators have been met.

The landfill operates under PADEP Solid Waste Permit No. 100403.  EPA has evaluated the closure and post-closure measures taken at the Facility under the PADEP permit.  EPA believes that the past actions and current/future requirements under the permit address the corrective action issues.

EPA issued a Corrective Action Statement of Basis (SB) in August 2014. The SB described the environmental conditions at the site and asked for public comments on EPA's tentative decision.  In September 2014, EPA issued a Final Decision requiring continued compliance with the PA Solid Waste Permit

Cleanup Background

The Seneca Landfill (formerly Vogel Disposal Services) is an operating Municipal Waste Landfill.  As such, current and future access is restricted to required operation and maintenance activity.  The facility is fenced to prevent unauthorized access.  Current and future groundwater use is restricted to monitoring and maintenance activities.

The Pennsylvania Department of Environmental Protection (PADEP) routinely inspects the facility for compliance with its permit requirements (Solid Waste Permit No. 100403).   Groundwater is monitored as part of the Facility-wide monitoring required under the State Permit.  There are currently nine groundwater monitoring wells; three upgradient wells, one side-gradient well, and five downgradient wells.  The groundwater is monitored on a quarterly schedule, as prescribed by the State Permit.
 
The groundwater beneath the Facility is contaminated with brines from past oil and gas drilling operations that were conducted near the Facility, and acid mine drainage from past mining operations.  Current monitoring results show no organic compounds in the groundwater.  Indicator parameters and metals are detected at elevated levels; primarily sodium, chloride, sulfate, iron and manganese.  Those parameters are present at elevated levels in both the upgradient and downgradient wells, and are attributed to former oil and gas drilling and coal mining operations near the Facility.

The Facility is located on Hartman Road in Lancaster and Jackson Townships, Butler County, Pennsylvania.  It is situated on approximately 268 acres of land just east of Harmony, Pennsylvania, and is surrounded by a mix of industrial property, farm land and wooded land.

The Facility is an active municipal waste disposal facility permitted under the Solid Waste Permit which was initially issued in July 1973 and most recently reissued in September 2017.  The Facility is also subject to the post-closure requirements of Resource Conservation and Recovery Act (RCRA) under the authorized state hazardous waste program.

The Facility landfill consists of four fill areas.  The four landfill areas occupy approximately 100 acres of the Facility.  Areas A, B, and C pre-date Area D.  Area D is the active landfill area.  It overtops part of Area A and all of Areas B and C.  Area A and Area B contain some hazardous waste.  They were closed under PADEP-approved closure plans, which are incorporated into and enforceable under the Solid Waste Permit.

Leachate from the Landfill is collected and transported by pipe to an on-site treatment system prior to discharge to Connoquenessing Creek.

Institutional and Engineering Controls at this Facility

The PADEP Solid Waste Permit imposes land-use restrictions on the property.  Current and future access is restricted to authorized personnel.  The facility is fenced to prevent unauthorized access.  The landfill sections are being capped as filing operations are completed in each section of Area D.  A RCRA cap will cover the entire landfill area when the landfill reached capacity, as prescribed in the PADEP Permit.  Current and future groundwater use is restricted to monitoring and maintenance activities.
