EP has produced innovative solutions and substantial savings for builders and owners before and during construction in the following areas:

Maintenance of Schedule and Budget

  • Coordination of environmental tasks between owner, construction manager, program manager, architects, designers, special inspectors, contractors, sub-contractors, state regulators, labor representatives, and field crews.
  • Installation of pre-task soil borings and test pits to better characterize soil disposal options and categorize soil in most-representative, least-cost manner.  This measure reduces stockpiled soil volume and accelerates disposal rate.
  • Application of state and federal regulations to manage highly contaminated soil as non-hazardous waste, resulting in over $2 million savings on one project.
  • Removal of heavily contaminated soil and obstructions during second shift and off-hour operations to minimize schedule impacts and disruptions to work force and neighboring businesses and residents.
  • Participation in project-wide task sequencing and scheduling to optimize simultaneous site remediation, environmental management, and construction task activities.
  • Development of detailed cost estimates for alternative environmental and construction measures and contingency options to support project planning.

Remedial Action Plan (RAP) Preparation, Interpretation, and Implementation

  • Interpretation of site conditions and RAP terms to provide developer, architect, and engineer with Basis of Design requirements to incorporate during preparation of Construction Documents and Contract Drawings.
  • Review of facility and site design elements and determination of remedial measures necessary to accommodate RAP requirements during site re-use.
  • On-site observation of construction activities to ensure RAP, specification, and contract conditions are met during construction.
  • Design data collection, including supplementing existing site characterization by installation of existing borings and test pits to reduce excavation volumes, reduce disposal costs, and avoid potential obstructions.
  • Oversight of perimeter community air monitoring program to prevent construction site organic vapors, odors, or nuisance dust from affecting neighbor businesses and residents.
  • Oversight of seven-acre HDPE liner system to isolate contaminated soil, consistent with RAP requirements.
  • Participation in public and private informational meetings to explain remediation measures and methods.


Soil Management and Disposal

EP has overseen the transportation and disposal of over 200,000 tons of polluted soil since 2002.  Management has involved:

  • Pre-categorization of soil to be excavated and disposed.
  • Preparation of bid and contract documents for procurement of waste transportation and disposal services.
  • Inspection of transportation and disposal insurance coverage.
  • Implementation of detailed waste generation and disposal tracking system, including use of random weight confirmation audit process.
  • Negotiation of best disposal facility terms and pricing.
  • Preparation of waste staging areas.
  • Coordination of excavated soil storage, loading, and transportation.
  • Preparation of disposal approval and transportation paperwork.
  • Evaluation of soil and identification of material suitable for on-site reuse in conformance with RAP and state regulations, producing substantial cost savings and schedule benefits.
  • Use of spray foam to minimize odors and vapor effects in worker breathing zone.


Remediation Standard Compliance

  • Interpretation and communication of CT Remediation Standard Regulation application to sites.
  • Achievement of state cleanup standards in all New England states through excavation, technology application, negotiation and favorable relationships with state and local regulators.

Construction Stormwater and Dewatering Permits

  • Preparation of  General Permit Registrations for construction stormwater management and erosion control
  • Routine inspection and evaluation of erosion control  measures
  • Specification and contract document preparation for automated vehicle decontamination stations (wheel wash) to reduce offsite sediment deposition
  • Preparation of dewatering wastewater discharge General Permit Registrations
  • Specification and contract document preparation for dewatering wastewater treatment systems
  • Preparation of Commercial Stormwater Discharge General Permit Registrations for post-construction operation of facility stormwater measures


Hazardous Waste Management

  • RCRA Contingency Plan Preparation
  • RCRA Awareness Training for customer personnel authorized to order waste disposal and sign disposal paperwork
  • Coordination of disposal of numerous hazardous and non-hazardous waste streams including petroleum and tar impacted soil, PCB-impacted articles, lead-impacted soil, ignitable wastes, and spent solvent-impacted soil.

Underground Storage Tank (UST) Decommissioning

Management and oversight of unforeseen and planned UST removal and abandonment in place, including:

  • Preparation of tank abandonment contracts and regulatory paperwork
  • Removal of numerous unanticipated tanks that have threatened to affect construction sequences or schedules
  • Direction of removal contractor activities, including tank cleaning, tank removal, and residual sampling
  • Negotiation and interaction with regulators regarding extent of further investigation or soil remediation
  • Abandonment-in-place involving tank testing to prove that release has not occurred, subsurface sampling to document line integrity, well abandonment and flowable fill placement to decommission tanks


Release Response

Management of all aspects of release response including:

  • Direction of short-term emergency response activities with state regulators
  • Negotiation with regulators to take over response activities on non-emergency basis
  • Review of site conditions to determine causes of release
  • Modification of site conditions to prevent further release
  • Removal of substantial contaminant mass from source area soil
  • Subsurface site assessment to determine degree and extent of release impact
  • Implementation of long term assessment measures to evaluate effects of release

Health and Safety

  • Preparation of CT DOT-compliant Health and Safety Plans
  • Provision of trained breathing zone monitoring technicians
