The Environmental Site Assessment has become the standard for meeting "due diligence" requirements necessary to be considered an "Innocent Landowner" in property transactions under United States Law. There are 3 Phases:

Crane.Phase I Environmental Site Assessment consists of a thorough investigation of the current and historical uses of the property in order to determine the potential for environmental risks associated with the property. The Phase I may or may not determine whether such risks are actually present.

A Phase II Environmental Site Assessment consists of subsurface exploration and testing to determine whether the suspected environmental impacts are actually present, and to determine the location and extent of the impacts.

A Phase III Remedial Action may be required when a Phase II identifies contamination above local regulatory levels. A successful Phase III action results in clean-up of he property and case closure.

A Transaction Screen is a low cost alternative to the Phase I ESA for properties which appear to have a low potential for environmental risks. For many smaller properties, a Transaction Screen will provide sufficient information to determine that a full Phase I investigation is not warranted.

PROJECT EXPERIENCE - Environmental Assessment & Remediation

Mr. Tiffany has conducted hundreds of Phase I and Phase II site assessments and remedial investigations and designed and managed dozens of successful remedial actions to convert impacted properties into saleable properties. Examples include:
  • Industrial Facility Decommissioning - Norwalk
    Project Manager for project to decommission and clean up aerospace machine shop facility in Norwalk. Previous site assessments by other consultants revealed the presence of oil and solvent contamination in soil and groundwater. Previous estimates of cleanup costs ranged up to $5M. Mr. Tiffany conducted remedial investigation, designed demolition and remediation projects, managed demolition and cleanup, and obtained site closure for a total cost to client of $750,000 including investigation, demolition, remediation, and oversight. Property sold for approximately $2.5M.

  • Brownfield Redevelopment - West Hollywood
    Formosa.Project Geologist for urban brownfield redevelopment project in West Hollywood. Site consisted of 6 industrial properties, with 4 separate major releases of fuels and solvents to soil and groundwater and numerous minor releases. Mr. Tiffany conducted remedial investigation and then managed oversight and monitoring of remedial actions during excavation for underground parking garage. Removal of 70,000 cubic yards of contaminated soil during excavation of the 210,000 cubic yard garage excavation, and associated construction dewatering, effectively remediated the environmental impacts to permit site closure. Property is currently being developed with a shopping center.

  • Brownfield Redevelopment - Santa Monica
    Big Tank.Project Geologist for urban brownfield redevelopment project in Santa Monica. Site consisted of former clay mine and brick manufactory with releases of fuels and lead-containing ceramic wastes. Mr. Tiffany conducted remedial investigation and then conducted oversight and monitoring of remedial actions during excavation for underground parking garage. Onsite treatment of 65,000 cubic yards of petroleum-contaminated soil and removal of 3,000 tons of lead-containing waste during excavation of the 300,000 cubic yard garage excavation effectively and economically remediated the environmental impacts to permit site closure. Mr. Tiffany developed a field screening method for classification of lead-containing waste, confirmed by laboratory analysis, which saved up to $1M in hazardous waste disposal costs. Property was subsequently developed with two large office towers.

  • Property Transfer - Los Angeles
    Drillrig.Project Manager for Phase I/Phase II site assessment of shopping center property on former oilfield near Farmers Market in Los Angeles. Researched oil production on property and conducted geophysical survey and Phase II subsurface site assessment to define extent of petroleum contamination and establish projected cleanup costs. Located two abandoned oil wells on site using geophysical survey and soil methane survey. Site assessment report and cleanup cost estimates were used to obtain environmental insurance to cap cleanup costs in the event of future development. Property was purchased by client and continues in service with existing shopping center.
