Land owners, lenders, insurers and investors can inherit liabilities for hazardous-waste disposal and other site risks under environmental laws and regulations that went into effect in 1980. The cost to remediate contaminated property can often exceed the value of the property itself. CGRS possesses the most effective skills, methods and technologies for performing both phases of environmental site assessments (ESAs) as well as assisting with hazardous waste management.

CGRS has in-depth experience performing due-diligence ESAs for all manner of properties including:

  • Undeveloped
  • Industrial
  • Commercial
  • Agricultural

CGRS’s ESA customers throughout the Western United States include:

  • Private citizens
  • Industrial corporations
  • Investment firms
  • Developers
  • Law firms
  • Insurance companies
  • Financial institutions

Phases of Investigation

Generally, ESAs are performed in phases, with a Phase I assessment consisting of a nonintrusive and qualitative investigation, which takes into consideration current and historical uses of the site and whether any conditions exist that indicate a release of hazardous material, such as petroleum or chemicals.

If the Phase I ESA determines a potential environmental risk is associated with the property, a Phase II investigation is recommended. Phase II ESAs involve analytical testing of:

  • Soil and water (depending on contamination source)
  • Building materials (asbestos or lead-based paint)
  • Underground storage tanks and piping (tank integrity testing)
  • Or electrical transformers (PCBs)

CGRS has extensive experience in generating Work Plans, Quality Assurance Project Plans (QAPP), and Sampling and Analysis Plans (SAP), all of which ensure the proper analytical data are generated for each project, and that all sampling and handling are done in accordance with written protocols.

Hazardous Waste Management

Wherever chemicals, fuels, or other hazardous materials are stored, processed or consumed, a risk of releasing that material to the environment exists. In the event of a hazardous material (HAZMAT) release, emergency responders must have all the necessary information to safely control the release and prevent injuries to the public or damage to the environment. For this reason, federal and state regulations require facilities that manage hazardous materials to maintain written HAZMAT Emergency Response Plans.

CGRS typical hazardous waste management services including:

  • Waste characterization, manifesting and disposal
  • Development of waste inventory programs
  • Development of hazardous material management and contingency plans
  • Remedial investigations
  • Liaison between clients and state and/or federal agencies
  • Hazard analysis and spill prevention, control and countermeasure (SPCC) planning
  • Addressing possible on- and off-site consequences and impact of potential releases of hazardous chemicals on humans, the environment and the economy

The SPCC Plan helps minimize the potential for oil product discharges at petroleum facilities and includes:

  • Employee-training protocol
  • Storage tank-inspection guidelines
  • Identifying failsafe engineering to prevent discharges
  • Secondary-containment design to prevent a discharge from impacting the environment in the event of a spill
  • Spill-response protocol
