Phase I Environmental Site Assessment

The Phase I ESA is performed to determine the presence of Recognized Environmental Conditions (RECs) in association with a property.  A REC is defined by ASTM E 1527-05 as the presence or likely presence of any hazardous substances or petroleum products on a property under conditions that indicate an existing release, a past release or a material threat of a release into the structures on the property or into the ground, groundwater or surface water of the property.  The following are examples of potential RECs:

Poor housekeeping and waste management practices
Stained soils
Regulatory violations
Documented discharges
Buried debris and dumping

Historical RECs may include previous land uses such as gasoline service stations, drycleaning operations, chemical manufacturing sites, and landfills.

Streamline is able to identify RECs through comprehensive research and documentation of the site’s history and surroundings, interviews with current and previous owners and/or occupants, as well as a visual inspection of the property's physical and environmental features.  The findings of each Phase I ESA study are documented in a well formatted report which is easy to read and understand.  Recommendations for additional assessment are typically provided in a separate cover letter.

The advantages of using Streamline for your Phase I needs include the following:

Dedicated Project Management - All of the work is completed by a single Environmental Professional (EP) to maximize efficiency while minimizing cost, and most importantly, risk .  Each of our scientists has an in-depth working knowledge of the liability issues associated with CERCLA, RCRA, State, and local environmental regulations.  Our broad experience is an invaluable asset for the Phase I marketplace. We understand manufacturing processes; we know the hazardous waste and petroleum rules; we can estimate cleanup costs accurately; and we find solutions where others find only problems.

Rapid Turnaround – Streamline is sensitive to situations when an ESA must be accomplished near the closing date of a transaction, usually with the entire transaction dependent upon the results.  Rapid turnaround in as little as five days can be accomplished in many circumstances. 

Phase II Sampling - If requested or recommended, Streamline will perform soil and/or groundwater sampling for physical evaluation of subsurface conditions.  Clearly, sampling is the best way to quantitatively minimize risk to our clients and to Streamline.  Streamline maintains a vast supply of environmental sampling equipment to conduct thorough subsurface investigations and establish soil and groundwater quality conditions on a variety of sites.

Options - Streamline offers a number of valuable options that can be implemented concurrently with a Phase I ESA at minimal additional costs.  These services can include asbestos and lead-based paint surveys, radon studies, mold evaluations, a variety of field-screening applications, and aerial photography services.

We understand that the risk tolerance of our clients varies; therefore our job is not to tell the client whether or not to become involved in a piece of property but rather to provide the client with the information they need to make a sound business decision.

Like many businesses, ours is referral based and we are happy to provide you with references for added assurance that Streamline is your first and best choice for environmental services.
