Phase I ESA in the State of Ohio are intended to identify Recognized Environmental Conditions (REC) in relation to a parcel of land or property.

When you buy land, you buy everything with it – known and unknown. An environmental site assessment is a report prepared by qualified environmenal professionals that identifies potential and/or existing environmental liabilities found on a parcel of land or property.

The main purpose of an ESA is to research, investigate, and inspect a property to assess if current or past usage may have created hazardous conditions that could pose an environmental or human threat. ESA’s also protect the buyer from potential environmental issues that maybe be unknown or unseen before the purchase. Many financial institutions require an ESA to help reduce their risk as well.

Our Phase I Environmental Site Assessment satisfies all of the requirements of the American Society of Testing Materials Standard Practice for Phase I Environmental Site Assessments and Environmental Protection.

Phase I ESA Frequently Asked Questions

What classifies as a REC?

RECs are the presence or likely presence of any hazardous substances or petroleum products on a property under conditions that indicate an existing release, a past release, or a material threat of a release into structures on the property or the ground, groundwater, or surface water of the property.

What type of report will be generated as a result of an investigation?

Aegis has developed a Phase I ESA protocol that satisfies the American Society for Testing Materials (ASTM) Standard Practice requirements for Phase I Environmental Site Assessments (E1527-13) and Environmental Protection.

What happens if a REC is identified on the property?

We will provide a professional opinion regarding the potential for contamination. When RECs are identified, and additional investigations are warranted, a Phase II investigation is generally recommended. If needed, we have the in-house expertise to deliver turn-key solutions that include further investigation and remediation.

How long does it take?

Generally, it takes 2 to 3 weeks to prepare a Phase I ESA. A Phase I report can be prepared in a shorter timeframe. However, the quicker the turn-around, the more likely there will be data gaps since not all information or data is readily available.
