Project Description


Sunbury Generating Station
Snyder County, PA

L.R. Kimball has provided Surveying/Mapping, Geotechnical and Project Engineering Services at the Sunbury Generating Station for more than 24 years.  These services began with the development of mapping for expansion of the ash basin when the facility was owned by PP&L, and then continued with coal stockpile volume assessments after the acquisition of the site by an affiliate of Robindale Energy Services, Inc.

When Sunbury Generation LP decided to decommission the coal fired power plant, L.R. Kimball assisted with the closure of the coal stockpile and ash basin areas.  This included geotechnical and groundwater investigations, topographic mapping and engineering design and permitting.  The ash basin was subsequently permitted as both a residual waste disposal facility and a permitted dam, and L.R. Kimball provided all necessary services for both the permit issuance and ultimate closure.  The coal stockpile area was also closed under the PADEP Act 2 program.

As part of the decommissioning process, L.R. Kimball also provided an assessment report and specifications for the demolition of the Sunbury Power Plant structure.  The first stage of that demolition was begun in 2019, with environmental cleanup followed by implosion of the main buildings.

L.R. Kimball provided  master planning for redevelopment of the former coal stockpile and ash disposal areas for mixed use industrial, commercial, residential and recreational use.  The plan included conceptual parcel, roadway, and utility layout on a 130 acre site spanning two municipalities.  The project proposed development of on-site canal and towpath remnants into a public trail adjacent to the Susquehanna River with plans for interconnectivity with existing nearby public parks.

Plans were developed for construction of 2 gas fired power plants on the site, the first of which (the 1124 MW Hummel Station) was constructed by Panda Power Funds, for which L.R. Kimball provided multiple engineering and permitting services.  The second plant is under development by Sunbury Generation LP and Arcova.

In addition, a multi-phased 39,000 square foot facility is under construction at the north end of the former coal stockpile area for INSA, LLC, for growing and processing medical marijuana.  L.R. Kimball provided multiple surveying, engineering and permitting services for this facility, which is anticipated to begin operations in early 2020.
