Large Publically Traded Oklahoma Based Exploration & Production Company

Centre & Clearfield County, PA

ARM has been providing comprehensive engineering design and environmental consulting across five counties in Pennsylvania to support this company’s natural gas well drilling and development operations in the Marcellus Shale formation:

Engineering & permitting services – Erosion and Sediment Control General Permits (ESCGP-1), Erosion and Sediment Control Plans, PADEP General Permits, Post-Construction Stormwater Management (PCSM) Plans, and Preparedness, Prevention and Contingency (PPC) Plans.  Air permitting for compressor stations, PADEP General Permits, Centralized Impoundment, PennDOT Highway Occupancy Permit and Driveway Permit, Water Management Plans (WMP), Water Supply Development permitting and consulting.

Centralized Impoundment

Natural resource services – ARM ecologists have been conducting site-specific wetland delineations, threatened and endangered species reviews, surveys, and clearances prior to site construction for pipelines, well pads and impoundments to ensure avoidance and minimization of impacts upon regulated resources and sensitive habitats.

Civil engineering services – ARM engineers have been performing pipeline work for 4.5 miles of 16-inch diameter pipe and 2.6 miles of gathering piping to well locations, compressor station and tap site layouts. This work has entailed stream and wetland crossing and highway boring design services, access road design, stormwater management, erosion control, graded well pad design, and design of a 31-acre centralized wastewater and fresh water storage impoundment system to support the drilling and development operations.

Natural resources
A strong working relationship between the client, wetland scientists, and project engineers has allowed for the development of a long-term natural gas project that minimizes environmental impacts and maximizes the use of previously impacted (strip-mined) land.

Services provided:

  • Conducted identification of regulated resources (wetlands/stream) early in the preliminary design phase allowing for design changes to avoid and minimize these resources
  • Wetland scientists delineated a total of 12 wetlands in a 134-acre investigation area (including three 3.6-acre well pads, a 36-acre centralized water storage impoundment system, 8, 400-linear feet of connecting pipelines and 7, 000 feet of access roads)
  • Use of Global Positioning System (GPS) navigation to guide the investigation and to immediately survey delineated wetlands and streams for inclusion on project mapping
  • Length of the regulatory review by the Pennsylvania Department of Environmental Protection was substantially reduced due to the use of general permits for wetland and stream encroachment
  • Biologists conducted a habitat suitability investigation for a Pennsylvania endangered plant (Carey’s smartweed, Polygonum careyi) along a 1.1 mile pipeline corridor within a 134-acre investigation area and a habitat assessment survey for the Pennsylvania threatened Allegheny woodrat (Neotoma magister) within and adjacent to an existing and planned pipeline corridor (57 acres)
  • Cooperative coordination with jurisdictional agency biologists/regulators throughout the investigation; Pennsylvania Department of Conservation and Natural Resource(PADCNR) and Pennsylvania Game Commission (PGC)
  • Successful completion of Allegheny woodrat habitat suitability survey within a short turnaround time; findings were approved by PGC
  • ARM’s wetland scientist recommended options to relocate a well pad to avoid wetland impacts and maintain required buffer distances for wetlands greater than 1 acre, in accordance with the PA Oil and Gas Act (Act 223)
