Developers

As a Developer, you know the importance and emphasis the government place on Environmental safety and due diligence on any land mass slated for housing or any type of development project. Phase 1 and Phase 2 Environmental Site Assessment are the best and recognized methods to determine that a piece of land or housing sites are contaminant and pollutant free.

There is a big risk involved when developing an environmentally contaminated property especially if hazardous waste contaminants were discovered on a property you have recently acquired.


Phase I and Phase II Environmental Site Assessments (ESAs)

The ESA report generated from a contaminated site is very important in guiding you through the clean up processes. This pertinent information answer your questions on what should be done to clean up the contaminants. For example, the Phase I and Phase II results can be used in your purchase agreement to require that the current landowner clean up the property prior to the sale, or reduce the cost of the property commensurate with the cost of remediation required. You can also use it to pursue acquisition and clean up alternatives to help control your environmental liability for the property.

Let AEA Environmental Services do Phase I and Phase II environmental site assessment studies prior to acquiring your property and minimize that risk.

Phase I and Phase II Environmental Site Assessment was developed to evaluate environmental concerns at sites changing hands that was previously for commercial purposes.


Phase I

The Phase I Environmental Site Assessments was established under the American Society for Testing and Materials (ASTM). ASTM E1527-13 is currently used as standard for addressing “Recognized Environmental Condition”  (REC)and the EPA “All‐Appropriate‐Inquiry” (AAI) aspect to the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA).

CERCLA is a government National policy, and procedures for containing or removing hazardous substances that have been released into the environment.  CERCLA also provides funding and guidance for cleaning up some abandoned and contaminated hazardous waste sites.

In accordance with the ASTM E1527-13, our highly trained professionals review current and historical records through referenced sources such as:

  • Aerial photographs,
  • Fire insurance maps,
  • Property tax files,
  • USGS topographic maps,
  • Land title records, with lien records for environmental liens or activity and use limitations.
  • Local street directories,

Current and past property use and condition interviews are held with owners, occupants, neighbors and local government officials. Because contamination could occur from the activities on nearby properties, the neighboring sites are also reviewed through Public records.

All ESAs are conducted by AEA’s environmental professionals who are trained in the appropriate standards and procedures.

Because the review of government records and interviews are time consuming, and to ensure a quality assessment, we advise that our clients allow sufficient time for the process.


Phase II

While Phase I ESA identifies potential contaminants and hazardous materials on the site, Phase II ESA involves sampling the potential contaminants and hazardous materials for laboratory analysis to confirm the presence of the contaminants and hazardous materials from the Recognized Environmental Condition (REC).

We adhere to the ASTM E 1903-11 Standard of practice for conducting Phase II Environmental Site Assessment (ESA).

Some Phase II ESA samples for confirmatory tests may include:

  • Surficial soil and water samples
  • Subsurface soil borings
  • Ground water monitoring well installation
  • Sampling, and analysis (may be appropriate on neighboring properties as well to determine the presence of contamination)
  • Drum sampling (if any were left on the property)
  • Sampling of dry wells, floor drains and catch basins
  • transformer/capacitor sampling for Polychlorinated Biphenyls (PCBs)
  • geophysical testing for buried tanks and drums
  • testing of underground storage tanks

Grant funds for assessing and cleaning up contamination may be available through a state or federal Brownfield grants program.
