Frequently Asked Questions

Environmental Site Assessments (ESAs) identify and assess property environmental threats and contaminants. An ESA evaluates the site’s hazardous substances, compounds, and pollutants to determine their health and environmental risks. Phase I and II ESAs are common.

A Phase I Environmental Site Assessment is a non-intrusive investigation of the property’s history, land use, and environmental damage. Site inspections, historical document reviews, and interviews with municipal officials, property owners, and other relevant parties are included. Phase I ESAs identify property-related recognized environmental conditions (RECs).

When a Phase I evaluation identifies an environmental threat, a Phase II Environmental Site Assessment is performed. It involves the sampling of soil and laboratory analysis to assess contamination and pollutant types. Phase II ESAs affirm or deny hazardous compounds and offer extensive cleaning details.

A qualified environmental consultant conducts Phase I and Phase II ESAs, and the report should follow ASTM standards.

Before a real estate transaction, a Phase I Environmental Site Assessment (ESA) is performed to detect and assess any environmental dangers or contaminants on a property. The evaluation identifies recognized environmental conditions (RECs)—hazardous substances or pollutants on the property or nearby that could influence its value or future tenants’ health and safety.

Phase I ESAs are needed for numerous reasons:

Due diligence: Lenders, investors, and other stakeholders involved in real estate transactions generally demand a Phase I ESA to identify environmental concerns.

Compliance: Federal and state laws like the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as the Superfund Law, and the Resource Conservation and Recovery Act (RCRA) require certain parties to conduct a Phase I ESA before buying or leasing a property or performing certain activities on it.

Liability: A Phase I ESA can identify and assess environmental liabilities that may affect a property’s value and the buyer, lender, or other interested party’s financial exposure.

Environmental Risk Management: A Phase I ESA can identify and assess a property’s environmental risks, which can inform property usage and remedial or mitigation decisions.

A Phase I ESA does not guarantee that a property is free of environmental dangers or contaminants, but it can uncover potential concerns and assess risk, which may lead to a Phase II ESA.

San Antonio Phase I Environmental Site Assessments (ESAs) require a certified environmental consultant. The consultant will examine the property’s history and use and test for environmental dangers and contaminants. The consultant will report their findings and recommendations. To determine the amount of environmental pollution, a Phase II ESA may be needed. The consultant should know the local, state, and federal regulations and the ASTM standard for Phase I ESAs.
