TSA and Phase I Phase II SIte Cleanup Construction

Environmental Assessments are being developed in order to attempt to clarify what constitutes the initial assessment of a property. Congressman Weldon introduced legislation that would clarify specifically what is necessary to meet the due diligence requirement of Superfund. It appears that the standards in development will divide the initial assessment into two categories: Transaction Screen Assessment (TSA) and Phase I.
   
 
TSA
The TSA, which involves a walk-through service, is conducted to evaluate a preliminary environmental assessment at the specific property. This is the initial look at a property, consisting of an objective observation. For smaller properties, it may be all that is necessary to give the parties involved with the property the information needed to make a decision regarding environmental concerns. It generally consists of a visual inspection of the site and adjacent properties, a search of government records, interviews with current owners and/or operators and other readily available information, such as equipment operation permits at the subject site. The procedures for commercial and industrial properties will generally be more comprehensive than those for residential or smaller commercial properties. The discretion of the person performing the Transaction Screen Assessment is important in determining how much information should be gathered on a subject property. Communication with the client is particularly important at this stage so that the client is aware of any applicable laws and regulations that may affect the decision on the depth of the assessment. Our Transaction Screen Assessment reports meet the ASTM E-1528, including property reconnaissance, site location map, site plot plan, inspection photographs, environmental government records, conclusion, and recommendation. The property reconnaissance categories consist of air pollutants, asbestos visual survey, PCB, UST, AST, hoist units, hazardous materials, unknown containers, distressed vegetation, stockpile soils, waste treatment units, solid waste disposals, chemical spills, pits, ponds, lagoons, biological hazardous wastes, radioactivity, etc.
   
 
PHASE I
The scope of services for the Environmental Site Assessment (Phase I) meets the ASTM E-1527, and includes the following tasks:

a. Site Reconnaissance: Visual investigation of the subject site to obtain information regarding obvious visual signs of adverse environmental conditions, contamination, hazardous material usage, storage and handling on and in the vicinity of the subject site. The property reconnaissance categories consist of air pollutants, asbestos visual survey, lead-based paint, PCB, UST, AST, hoist units, hazardous materials, unknown containers, distressed vegetation, stockpile soils, waste treatment units, solid waste disposals, chemical spills, pits, ponds, lagoons, biological hazardous wastes, radioactivity, etc.

b. Provide Site Location Map

c. Hydrogeology survey

e. Site Plot Plan: The site plot plan generally consists of property boundary, dimension, building or factory location, equipments, environmental concerned area, scale, date, four sides, etc.

f. Neighboring Property Survey: Visual survey of the adjacent properties uses and determination of any current nearby operations that may potentially pose an environmental risk to the subject site. Environmental effect from the adjacent properties may be related to Hydrogeologic study, lithologic information, hazardous material use, contamination, and environmental government records.

g. Environmental Related Government Records Search: Review of a 1-mile radius based on Environmental Regulatory Agency's search records. EPC will use its best efforts but makes no claims as to the completeness or accuracy of the referenced government sources or the completeness of the search.

h. Historical review of tenants and/or building permits available, using database or the city records to identify any potential past on-site operation, which may have environmental implications.

i. Conclusion and Recommendation: It generally consists of the reconnaissance summary, site information, decision regarding environmental concerns, and recommendations with estimated cost breakdown.
