Casey Resources, Inc. has the capabilities, resources, and personnel to conduct Environmental Site Assessments (ESAs)
A Phase I Environmental Site Assessment is a report prepared for a real estate holding which identifies specific environmental contamination liabilities. The analysis, often called a Phase I ESA, typically addresses both the underlying land as well as physical improvements to the property; however, techniques applied in a Phase I ESA never include actual collection of physical samples or chemical analyses of any kind. Scrutiny of the land includes examination of potential soil contamination, groundwater quality, surface water quality, and sometimes issues related to toxic uptake by biota. The examination of a site may include: definition of any chemical residues within structures; identification of possible asbestos containing building materials; inventory of toxic substances stored or used on site; assessment of mold and mildew; and evaluation of other indoor air quality parameters.
Actual sampling of soil, air, groundwater, and/or building materials is typically not conducted during a Phase I ESA. The Phase I ESA is generally considered the first step in the process of environmental Due Diligence. This type of study is alternatively called a Level I Environmental Site Assessment. Standards for performing a Phase I ESA have been promulgated by the American Society for Testing and Materials (ASTM) in Standard E1527-05. If a site is considered contaminated, a Phase II ESA may be conducted in accordance with ASTM test E1903, a more detailed investigation involving chemical analysis for toxics.
Actions Triggering a Phase I ESA
- Purchase of real property by a person or entity not previously on title.
- Contemplation by a new lender to provide a loan on the subject real estate.
- Partnership buyout or principal redistribution of ownership.
- Application to a public agency for change of use or other discretionary land use permit.
- Existing property owner's desire to understand toxic history of the property.
- Compulsion by a regulatory agency who suspects toxic conditions on the site.
There are several other report types that have some resemblance in name or degree of detail to the Phase I ESA:
Phase II Environmental Site Assessment is an investigation which collects original samples of soil, groundwater or building materials to analyze for quantitative values of various contaminants. This investigation is normally undertaken when a Phase I ESA determines a likelihood of site contamination. The most frequent substances tested are petroleum hydrocarbons, heavy metals, pesticides, solvents, asbestos, and mold.
Phase III Environmental Site Assessment is an investigation involving toxic remediation of a site. This study normally involves assessment of alternative cleanup methods, costs, and logistics. The associated report details the steps taken to perform site cleanup and the follow-up monitoring for residual contaminants.
Environmental Assessment has little to do with the subject of toxic liability, but rather is a preliminary study to an Environmental Impact Statement, which identifies environmental impacts of a land development action and analyzes a broad set of parameters, including biodiversity, environmental noise, water pollution, air pollution, traffic, geotechnical risks, visual impacts, public safety, and toxic issue.
