ASTM Phase I Environmental Site Assessment

Our Phase I Environmental Site Assessment (ie. Phase I, Envrironmental Assessment) studies follow the format of ASTM Standard 1527 for Phase I Environmental Assessment studies and include a physical inspection of the site, a review of relevant records, and interviews with occupants, owners, neighbors and selected officials. The Phase I scope is often expanded to address issues specific to the subject property.  All of our Phase I Environmental Assessment Studies are performed by Licensed Professional Engineers who are also Environmental Professionals trained in Phase I studies as defined by the standard.  In addition, our engineers come with local knowledge which is often vital to determining the outcome of the Environmental Assessment.

The primary intent of our Phase I Environmental Site Assessment studies is to identify Recognized Environmental Conditions (RECs) associated with each property, as well as Business Environmental Risks (BERs) as defined within ASTM.  This site visit includes an inspection for issues identified as within the scope of ASTM 1527 for Phase I Evironmental Assessments including:

  • Hazardous Materials Storage & Handling
  • Waste Generation, Storage, Disposal & Emissions
  • Underground Storage Tanks
  • Aboveground Storage Tanks
  • Polychlorinated Biphenyls (PCBs)
  • Stained Soil
  • Drums or Unidentified Containers
  • Drains or Sumps
  • Pits, Ponds, or Lagoons
  • Wells
  • Septic Systems

In addition to the site inspections, we conduct research as part of the Phase I Environmental Site Assessment scope as follows:

  • The apparent current and prior uses of all adjacent properties with respect to the potential for migration of contaminants to the subject property.
  • Readily available public records (local, state and Federal) and previous reports and studies to identify existing or potential sources of contamination to the site.
  • Interview present or past owners or tenants or other knowledgeable persons to the extent available, to assess their knowledge of stored, created or discharged hazardous materials or waste, and review as to whether appropriate procedures, safeguards, permits and notices are in place.

Unless directed by our client, our Phase I Environmental Assessment scope will not include any asbestos sampling or other issues defined as out of scope under the ASTM methodology.  If these additional services are requested, a separate proposal can be prepared.

Sometimes, the degree or even existence of contamination cannot be confirmed without a Phase II Environmental Assessment investigation. Criterium Engineers can coordinate Phase II Environmental Assessment investigations, but does not perform them. We will not recommend unnecessary additional studies when the risk is deemed low.
