  • Subsurface Investigations
  • Monitoring Well and Piezometer Installations
  • Foundation Design Recommendations
  • Slope Stability Analysis
  • Remedial Designs (as they relate to construction, mining, waste disposal, environmental remediation, and other projects)


POTESTA's usual procedure is to attend an initial meeting with the client to establish requirements and expectations, conduct a preliminary site reconnaissance, and develop a recommended exploration program for your review and approval. Supplemental information from the local area is then obtained from readily available sources to assist the engineer or geologist in making final recommendations.

POTESTA can provide field engineers and geologists who are knowledgeable using the latest technologies to assist in collecting and analyzing samples. Our knowledge of the proper procedures and familiarity with local conditions allows office and field personnel to adjust the investigative plan if unanticipated field conditions are found.

Our staff is familiar with the following items which can be associated with subsurface exploration:

  • Drilling and Rock Coring Techniques (augers, rotary bits, Geoprobe™, etc.)
  • Sample Collection Methods (split spoons, shelby tubes, Geoprobe™ sleeves, etc.)
  • Classification and Logging of Soil and Rock Samples
  • Monitoring Well and Piezometer Installation


Slope stability is often a major concern during the design and construction phases of many projects, especially those located in the Appalachian terrain. POTESTA's engineers are familiar with the various methods utilized to predict slope stability and are capable of performing the related analyses. Slope stability is critical for many projects such as analysis of existing or proposed soil embankments, rock fills, dam analysis and design, landfill design and operation, estimating the causation of slope failure, and designing remedial measures. Analyses can involve circular or sliding block methods, interface friction angles, and estimation of the strength parameters of the soil or rock. Slope stability analyses are performed on one of the most technologically advanced computer programs available and can be modified using site specific data.

POTESTA's engineers can also develop preventive measures during initial project design or recommendations to repair slope failures. Based upon the project circumstances, our engineers will consider various remedial measures such as regrading the site to obtain more suitable conditions, management of groundwater, and design of retaining structures. Our staff is familiar with a wide variety of retaining structures, including gabion baskets, soldier beam and lagging walls, sheet piles, reinforced concrete and reinforced earth slopes.


POTESTA's staff has experience with various types of foundations and will recommend the appropriate type of foundation given the anticipated application and site conditions. The different types of foundations with which our staff is familiar are spread and strip footings, steel piles, auger-cast concrete piles, drilled piers, and reinforced mats.

Preliminary foundation design recommendations and cost analyses are commonly performed during the initial phases of a project to assist in determining project feasibility. As project planning progresses, the preliminary alternatives will be revised into a final recommendation which can then be incorporated into the project's construction documents or developed as an independent package for presentation to the contractor.

The final recommendation can include construction drawings, technical specifications, recommendations for allowable bearing capacity, engineer's construction cost estimate, and contractor's bid sheet.

GIS Services

Spill Prevention, Control, and Countermeasure (SPCC) Plan

Spill Prevention, Control, and Countermeasure (SPCC) Plan

The Federal Oil Pollution Prevention regulations (40 CFR Part 112) include requirements to prevent discharges of oil from reaching navigable waters or adjoining shorelines. As a consequence, the EPA requires that certain facilities prepare, amend and implement Spill Prevention, Control, and Countermeasure (SPCC) Plans. If a facility has a total aggregate aboveground storage capacity exceeding 1,320 gallons of oil or oil-based products (for containers of 55 gallons and greater) or underground storage capacity exceeding 42,000 gallons of oil or oil-based product, it is subject to SPCC regulations. Unlike oil spill contingency plans that typically address spill cleanup measures after a spill has occurred, SPCC Plans ensure that facilities put in place containment and other countermeasures that would prevent oil spills that could reach navigable waters. Owners or operators of facilities that drill, produce, gather, store, process, refine, transfer, distribute or consume oil or oil products are subject to the requirements of the SPCC rule.

The SPCC regulations define "Oil means oil of any kind or in any form, including, but not limited to: fats, oils, or greases of animal, fish, marine, mammal origin; vegetable oils, including oils for seeds, nuts, fruits, or kernels; and other oils and grease, including petroleum, fuel oil, sludge, synthetic oils, mineral oils, oil refuse or oil mixed with wastes other than dredged spoil."

A written, certified copy of an SPCC Plan is required to be maintained on site. POTESTA offers broad, in-depth experience and expertise to support clients in complying with these regulations. Our engineering staff, including Registered Professional Engineers, can assist with developing or amending your SPCC Plan. POTESTA can review and certify your self‑developed plan, amend your plan to meet the new requirements or prepare a new plan for you. The regulations require that a Registered Professional Engineer certify that the SPCC Plan has been prepared in accordance with "good engineering practice, including applicable industrial standards."

POTESTA has assisted numerous clients in evaluating their facilities and preparation and certification of SPCC plans. Clients include small commercial businesses, large industrial and chemical complexes, bulk storage facilities, oil and natural gas production companies, natural gas interstate transportation and storage facilities and mining and timbering operations.

Elements of the SPCC Plan are to include:

  • Facility description with a diagram and emergency contact information.
  • Clean up and discharge notification procedures.
  • Tank information.
  • Secondary containment or other discharge prevention methods.
  • Countermeasures for spill containment.
  • Potential spill predictions.
  • Inspection and test procedures.
  • Personnel training.
  • Site security.
