Last month I discussed some of the common issues that may be encountered during the procurement, initiation and organization of Phase One Environmental Site Assessments (ESA). This month I will discuss ‘Procedural’ errors related to ESA Research that may occur while conducting a Phase One ESA. Depending on the type of ESA (CSA, RSC, ASTM, Oil & Gas, etc.) there are specific research requirements for mandatory and/or optional data to be reviewed, historical time frame, and search distances – all of which can vary significantly with the respective regulatory regime. Failure to consider and incorporate the specific requirements can lead to regulatory rejection, project delays and unhappy stakeholders. Regardless of the specific research requirements, the consultant must always gather sufficient information to provide an accurate, reliable and defensible assessment of actual and potential liabilities that may be present. Some of the more common deficiencies I encounter during peer review of Phase One ESA reports include:
For the next blog(s) in this series I will discuss some of the problem areas around flawed or deficient ESA interviews and site inspections.
