CP Environmental Group -

Wetlands Delineation and Report for a planned Marcellus Shale pipeline and drilling pad site located in north central Pennsylvania.  Work was performed without safety incident in rugged terrain known to contain timber rattlesnakes and ticks.  GPS equipment capable of use with heavy canopy cover was used for field delineation to allow easy correlation with professional survey and GIS maps.

Wetlands Identification Consulting Services were contracted during the planning phase of siting a potable water withdrawal pipeline for use during Marcellus Shale gas well drilling and completion operations.  By visiting the site during the early stages of the planning process, alternative routes were identified that saved wetlands mitigation construction costs.

Marcellus Shale Pipeline Support Services - Mine subsidence investigation at proposed natural gas compressor location, Shinnston, WV. Implemented a geotechnical drilling program to evaluate rock subsidence potential beneath the proposed natural gas compressor pad. The proposed compressor pad surface was located approximately 125 feet above the underlying abandoned Pittsburgh Mine workings which averaged about 6 feet in thickness. Available mine maps of the area indicated several episodes of mining in the Pittsburgh with reported retreat mining as the last activity prior to closure. The project drilling program was designed to evaluate the integrity of the roof rock, extent of the vertical cave-in across the site and presence of groundwater in the mined interval. A CPEG geologist was on site during drilling operations to direct the work, log rock core and make geologic interpretations. In addition, the CPEG geologist prepared a geologic evaluation report based on data obtained in the field cross-referenced with published geologic and mining data, and aided in incorporation of the geologic information into the development of the geotechnical engineering evaluation, provide by another subcontractor, to provide the client a realistic assessment of potential mine subsidence and possible mitigation measures.

Beneficial Use Permit preparation for utilization of Short Paper Fiber® (SPF) for capping coal mining spoil area to address acid mine drainage near Uniontown, Pennsylvania. Project included extensive interaction with PA DEP Abandoned Mine Land group, development of the site grading plan to facilitate SPF placement as well as the Erosion and Sedimentation Plan development.

Hydrogeologic permitting and compliance groundwater monitoring for two municipal solid waste landfills in western Pennsylvania. Work included detailed assessment of site hydrogeological and geologic parameters and development of a detailed site groundwater monitoring system, evaluation of former underground coal mining in the site vicinity with respect to hydrogeological conditions and site stability in support of landfill construction. Extensive interaction with PA DEP personnel. Landfill construction project management support. Management of hazardous waste assessment, excavation and disposal and associated permitting at one of the solid waste facilities.
