In environmental assessments, what acreage is required for Phase I pollution plans?

In the context of environmental assessments, a Phase I Environmental Site Assessment (ESA) is a crucial step to identify potential contamination and evaluate the environmental conditions of a property. The standard requirement for conducting a Phase I ESA typically revolves around the specific acreage of a property.

When it comes to the threshold for requiring a Phase I ESA, the common standard is set at 5 acres. This means that for any property that is equal to or greater than this size, a Phase I assessment is generally recommended to assess any potential environmental hazards or liabilities related to past or current land use.

This acreage requirement is aligned with federal guidelines and provides a balance between thorough environmental scrutiny and cost-effectiveness for the assessment process. Properties smaller than 5 acres may still undergo an assessment, but the standard regulatory push is for those at or exceeding this threshold to ensure sufficient detail is captured regarding potential contaminants that might affect human health and the environment.
