Limit Future Liability and Satisfy Due Diligence Requirements
Evaluate the environmental risk of acquiring, leasing or divesting property.
TRC’s environmental phase 1 site assessments review current and historical information on your property and evaluate the risks of developing property for other uses. The Phase I Environmental Site Assessment (Phase 1 ESA) identifies Recognized Environmental Conditions (RECs) pursuant to ASTM standards through comprehensive evaluations of site history and current environmental reports. Through this, we can assess if the property currently or has at any point in the past posed a threat to the environment or the health and safety of the surrounding community.
Facilitate Successful Property Transactions
Environmental site assessments are often a requirement for anyone participating in a property transaction, including owners, buyers and tenants, as well as lenders and property managers. By completing this evaluation prior to purchase, stakeholders can qualify as an innocent landowner, contiguous property owner or bona fide prospective purchaser and avoid Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) liability. Many lending institutions also require environmental site assessments as part of the due diligence process.
At TRC, we have led thousands of environmental site assessments, protecting our clients from being held liable under environmental compliance regulations. Our Phase 1 ESA professionals have worked with lending institutions, real estate developers and public and private entities who demand excellence, and our due diligence has delivered. Together with our Transaction Advisory Services (TAS) team, they develop thorough and detailed assessments that limit future liability and meet innocent purchaser defense requirements.
