While a Phase I Environmental Site Assessment (ESA) is a common method for identifying environmental liabilities during transactional due diligence, the ASTM International standard for Phase I ESAs (E1527-13, with proposed E1527-21 awaiting adoption) omits regulatory compliance from its scope. For properties containing operations that may be applicable to environmental compliance regulations, performing a limited environmental regulatory review can identify potential deficiencies with the environmental management of the facility. A limited environmental compliance review typically evaluates the presence of material findings that may exist in a facility’s management of its environmental compliance requirements. Material findings are defined as a condition of non-compliance that could necessitate expenditures, not including attorney fees or regulatory agency penalties, in excess of a specified dollar amount or materiality threshold. The materiality threshold is based on the client’s risk tolerance and is often in the range of $50,000. However, this amount is arbitrary and can be revised as appropriate. Non-material deficiencies, those identified below the materiality threshold, would still require action but are within the client’s risk tolerance.
