Environmental Site Assessments (ESA) Phase I and Phase II
The purpose of a Phase I Environmental Site Assessment is to gather sufficient information to develop an independent professional opinion about the environmental condition of the property and to identify actual or potential environmental contamination, which may impact the property value or affect claim to an “innocent land owner” exemption following acquisition (United States Environmental Protection Agency Environmental Assessment Standards). This can include the identification of or the presence or likely presence of any hazardous substances or petroleum products on a property. These identified substances or products can indicate an existing release, a past release, or a material threat of a release into structures on the property, the ground, groundwater and/or surface water.
Phase I Environmental Site Assessments (Phase I ESAs) are often required during real estate transactions. Phase I ESAs are common when commercial and/or industrial properties are sold, re-developed, or re-financed. A Phase I Site Assessment is an essential part of the “due diligence” process during these transactions by identifying and quantifying environmental concerns (e.g. hazardous waste, abandoned storage tanks, underground tanks, etc.) found onsite. Onsite verification of environmental concerns during the Phase I ESA can help lenders and buyers identify and minimize environmental liabilities. A thorough Phase I ESA can expedite real estate transactions, facilitate re-financing of a property, minimize project delays on site re-development projects, and save buyers thousands of dollars.
A Phase II ESA is conducted if issues were identified during the Phase I process. A Phase II ESA is a detailed study where actual physical environmental samples are collected and analyzed to identify if there is contamination. If so, Phase II ESAs will characterize the type, distribution and extent of hazardous substances in the environment.
Arroyo staff have extensive experience in data acquisition regarding Phase I and Phase II ESA’s which encompasses the collection of soil, surface water, groundwater and biological samples for various environmental studies. Also, Arroyo staff has experience working at one of Texas’ environmental contaminants labs analyzing soil, water and biological samples for metals and organic compounds, and therefore is knowledgeable of all sample collection and analysis protocols.
Arroyo staff have ESA Phase I certifications, and are experienced with project planning and design of Phase I and Phase II ESAs, particularly data acquisition (including long-term monitoring), data analysis and reporting. Related to this, experience also consists of projects in which endangered species and/or endangered species habitat was potentially impacted by concerns found during the Phase I ESA process. Endangered species experience is comprised of the review, assessment and monitoring of identified endangered species and/or endangered species habitat.
