Leigh Environmental has conducted multiple Phase I and II Environmental Assessments throughout the United States. By adhering to EPA’s “All Appropriate Inquiry” and ASTM E 1527-13 standards, LEL’s assessments are compliant with EPA’s Brownfields program. LEL specializes in assisting with the SBA Loan process by performing environmental site assessments with a quick turnaround.


The purpose of the PHASE I Environmental Assessment is to define good commercial and customary practice in the United States of America for conducting an environmental site assessment of a parcel of commercial real estate with respect to the range of contaminants within the scope of Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and petroleum products. As such, this practice is intended to permit a user to satisfy one of the requirements to qualify for the innocent landowner defense to CERCLA liability: that is, the practices that constitute all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice.


The purpose of the PHASE II Environmental Assessment is to further evaluate a parcel of commercial property with recognized environmental conditions normally called out from a PHASE I. The primary objectives of conducting a PHASE II are to evaluate the recognized environmental conditions identified in the PHASE I, 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 (Comprehensive Environmental Response, Compensation and Liability Act).
