Environmental Hazard Control, Inc. performs all environmental site assessments according to the American Society for Testing and Materials (ASTM), Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process, E 1528-00.  This practice is intended to permit a user to satisfy one of the requirements to qualify for the innocent landowner defense to CERCLA liability.

The purpose of the environmental site assessment is to identify, to the extent feasible pursuant to the ASTM process, recognized environmental conditions in connection with the property.  The objective is to provide reasonable assurance that recognized environmental conditions have been addressed.  The term recognized environmental condition means the presence or likely presence of any hazardous substance or petroleum product on a property under conditions that indicate an existing release, a past release, or a material threat of a release of any hazardous substances or petroleum products into structures on the property or into the ground, groundwater, or surface water of the property.  This information is evaluated and a professional opinion is rendered in regards to further recommendations and remediations if necessary.  

According to ASTM a Phase I Environmental Site Assessment shall have four components:

  1. A Records Review of Federal, State, and Local regulatory environmental databases, including: NPL, Delisted NPL, NPL Liens, CERCLIS, CERC-NFRAP, CORRACTS, RCRIS-TSD, RAATS, RCRIS, HMIRS, PADS, ERNS, FINDS, TRIS, TSCA, MLTS, STATE LF, State Hazardous Waste, State LUST List, State UST, State AST, and State Oil and Gas.  The Records Review also includes review of any historical data that may indicate past use of the subject site, including: aerial photographs, fire insurance maps, historical topographical maps, USGS 7.5 minute topographical maps, recorded land title records, soil conservation maps, and City Directory Searches.
  2. An on-site inspection that involves visual and physical observation of the subject property, noting the uses (past and present) and condition, general site setting, and any geologic, hydrogeologic, hydrologic, and topographic conditions.
  3. Interviews and to the extent feasible any past owners and occupants.
  4. A report of the findings for the Phase I Environmental Site Assessment and any recommendations for Phase II Testing
