Phase I & II Site Assessment


ERA’s goal is to form a strategic partnership with our clients to help manage risks associated with property transactions.

 
    Phase I Site Assessment:
  • ERA Scope of Work for performance of Environmental Site Assessments (ESAs) is in compliance with American Society for Testing and Materials (ASTM) Standard E1527-94/97/00/05 and the USEPA 2005 All Appropriate Inquiries Rule for Phase I Assessments. ERA will often tailor the process and final report to match our client’s particular requirements. The general purpose of the ESA process is to identify potential sources of environmental concerns that might exist at or near the subject property, and to make relevant recommendations as to the need for further investigations or analytical work to make more definitive conclusions regarding the presence and extent of potential contamination.
  • Sources of environmental impacts include hazardous substances and waste as defined by or listed under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and/or Resource Conservation and Recovery Act (RCRA), polychlorinated biphenyls (PCBs), asbestos, and petroleum products and by-products. Typically, ESAs involve a historical review of the subject site and area land use, a regulatory status review, a site geological analysis, a site and area reconnaissance, and a report detailing the findings, conclusions and recommendations.
  • ERA staff have audited/inspected virtually every type of residential, industrial, and/or commercial operation including: private and public schools, vacant land transfers, communications tower sites; rocket test laboratories; commercial aviation facilities; waste to energy plants; laundry and household product manufacturing plants; electronics and printed circuit board manufacturing operations; metal finishing operations; bulk petroleum storage facilities; aerospace manufacturing plants; military installations; landfills; educational facilities; and retail operations ranging from individual storefronts to full-size regional shopping malls.
  • Our capabilities are further enhanced by the number of multi-site, multi-year Phase I programs conducted for municipal and federal entities, including redevelopment agencies, financial institutions, transportation clients, and private developers.



 
    Phase II Site Assessment:
  • The primary objectives of conducting a Phase II ESA are to evaluate the recognized environmental conditions or potential environmental conditions identified in the Phase I ESA or transaction screen process for the purpose of providing sufficient information regarding the nature and extent of contamination to assist in making informed business decisions about the property; and where applicable, providing the level of knowledge necessary to satisfy the innocent purchaser defense under CERCLA.  ERA follows ASTM E1903 - 97(2002) and current standard of care protocols for conducting Phase II assessments.  In addition to the standard practices outlines in ASTM E1903, ERA may utilize a range of customized solutions depending on each projects needs. Of particular note is ERA’s use of multi-increment sampling methodologies and the utilization of geographic information system to manage large-scale sampling regimes.
  • As noted elsewhere, ERA staff have been on-call consultants to the HDOH during the years 1999-2005.  As such, ERA staff worked in collaboration with the HDOH to develop the first protocol for multi-increment soil sampling used in Hawai‘i which has served as the basis for all other consultant multi-increment protocols.  Multi-increment soil sampling offers several advantages over traditionally discreet sampling.  Multi-increment samples provide precise representation of the mean contaminant concentrations in decision units, and are far more cost-effective than discreet sampling. An equivalent protocol using discreet sampling would require that an average be calculated from the collection and analysis. Although more effective at determining concentration gradients and “hot spots”, this would be economically inefficient. Generally, site characterizations using discreet sampling methods therefore focus on a much smaller number of collected samples and a significantly more limited extent. Data from a single multi-increment sample rather than a few discreet samples is therefore considered more representative of overall site conditions (the multi-increment sampling approach provides a representative average concentration over the decision unit).ERA also integrates the sampling process into a geographic information system (GIS).  This system enables ease of planning to develop the most cost effective sampling plans, while providing graphical results delivery of contaminant concentrations.

 
 

 
    Phase III Environmental Site Assessment:

  • The primary objectives of conducting a Phase II ESA are to remediate environmental conditions identified in the Phase II Investigation.  ERA may utilize a range of customized solutions depending on each projects needs and obtain necessary governmental approval.
