Phase 1 ESAs cannot completely eliminate the potential for recognized environmental conditions related to a property to not be identified. A user of a Phase 1 ESA may also be further be limited, in that the extent of inquiry cannot be exhausted beyond the cost and time-efficient use of the resources utilized for the assessment. A Phase 1 ESA may also be limited by the property itself. Not every property will mandate the same level of environmental assessment. Only the current conditions of the property, during the time of the assessment, can be judged; not the previous or developing state.
