Phase I/Phase II
Environmental Site Assessments

 

Hydro Geo Chem performs Phase I and Phase II Environmental Site Assessments (ESAs) that meet the industry standard for environmental due diligence services for acquisitions and financing of commercial and industrial real estate and related consulting services. Environmental assessments associated with these transactions often reveal recognized environmental conditions (RECs) that require follow-up and documented resolution. Our professionals follow the due diligence process from inception through completion, and when RECs are encountered can identify a path that leads to a satisfactory outcome for all parties involved within the due diligence timeframe.

Phase I ESAs are conducted in accordance with ASTM E1527-13 and satisfy the Federal All Appropriate Inquiries rule in 40 CFR 312 to satisfy the requirements of Section 107(a)(1) of CERCLA. The site visit, and other major portions of the Phase I ESA are conducted by experienced Environmental Professionals. Our senior professionals have a history of ESA projects involving successful real estate acquisitions and redevelopment in nearly every state and metropolitan area in the western United States. Our professionals are familiar with local conditions and regulatory settings in these markets, for projects ranging from transactional screening assessments to complete Phase I ESAs, and where necessary Phase II and Phase III responses to findings. Hydro Geo Chem’s professionals are also remediation and risk assessment experts, with extensive experience from the design phase to implementation and completion of remedial and corrective actions. Where applicable, risk assessment and site-specific administrative controls can be recommended, saving the client both time and money.

Hydro Geo Chem’s client experience includes real estate investors taking equity positions in national and international projects; banks and other mortgage lenders; multi-family and single-family subdivision developers; and more. In many instances work for our clients includes portfolios of properties. For each project, our objective is to identify the specific requirements of the project and match them with an appropriate scope of investigation, and to then conduct additional assessment to remediation/regulatory closure, as necessary, in a timely manner. Through our experience working on projects funded by EPA Brownfields grants, Hydro Geo Chem has the ability to understand brownfields transactions from not only a technical standpoint but also from land-development and regulatory perspectives. We provide Phase I ESAs for Brownfields projects, and when Phase II ESAs are recommended we also provide Sampling and Analysis Plans (SAPs) and other required documents prior to initiating Phase II/III activities.

Phase I ESA projects frequently include additional services specific to the type of asset and interests of the client, such as requests for the investigation of the presence of asbestos. Hydro Geo Chem’s staff also includes EPA-certified asbestos building inspectors who have extensive experience to conduct limited transactional asbestos surveys and complete demolition asbestos surveys. Other common additions to the due diligence scope of work conducted by Hydro Geo Chem can include research and testing for radon, mold, and vapor intrusion issues.
