1. INTRODUCTION<br />
In general, ESAs (<strong>Environmental</strong> <strong>Site</strong> <strong>Assessment</strong>s) are conducted in response to two federal laws:<br />
CERCLA (Comprehensive <strong>Environmental</strong> Response, Compensation and Liability Act) <strong>of</strong> 1980 (Public<br />
Law #96-510) as amended by SARA (Superfund Amendment and Reauthorization Act) <strong>of</strong> 1986 (Public<br />
Law #99-499) and RCRA (Resource Conservation and Recovery Act) <strong>of</strong> 1976 (Public Law #94-580)<br />
as amended by HSWA (Hazardous and Solid Waste Amendments) <strong>of</strong> 1984. RCRA deals with waste<br />
management including the manufacture, storage, transportation, use, treatment, and disposal <strong>of</strong><br />
wastes including hazardous waste. HSWA amended RCRA by establishing bans and restrictions on<br />
the disposal <strong>of</strong> untreated hazardous waste on land; created USEPA’s (United States <strong>Environmental</strong><br />
Protection Agency) RCRA Corrective Action Program; and initiated regulation <strong>of</strong> USTs (Underground<br />
Storage Tanks). CERCLA establishes liability that forces cleanup costs <strong>of</strong> contaminated sites to<br />
responsible parties. SARA modified CERCLA to provide defenses to the liability provisions for<br />
contaminated sites.<br />
Property owners have three defenses to CERCLA liability. They are an act <strong>of</strong> God, an act <strong>of</strong> war, and<br />
an act or omission <strong>of</strong> a third party. The "third party defense" is supported by establishing that "... the<br />
defendant (a) exercised due care with respect to the hazardous substance concerned, taking into<br />
consideration the characteristics <strong>of</strong> such hazardous substance, in light <strong>of</strong> all relevant facts and<br />
circumstances, and (b) took precautions against foreseeable acts or omissions <strong>of</strong> any such third party<br />
and the consequences that could foresee-ably result from such acts or omissions." These two<br />
defenses are commonly referred to as "due care" and "due diligence", respectively. In addition, SARA<br />
provides government agencies an additional defense known as "eminent domain". Case law defines<br />
"sovereign immunity" which provides another layer <strong>of</strong> defense for government agencies.<br />
As directed under the Small Business Liability and Brownfield Revitalization Act, the USEPA published<br />
40 CFR Part 312, also known as the All Appropriate Inquiry Rule or AAI, on November 1, 2005. This<br />
manual has been revised based in part on the AAI rule. The other revisions in the manual are based<br />
on several factors specific to transportation project planning. All transportation projects that receive<br />
federal and/or state funding must address several environmental concerns under the National<br />
<strong>Environmental</strong> Policy Act (NEPA). As required by NEPA, ODOT must consider and potentially<br />
mitigate the impacts to historic and archeological resources, wetlands, endangered species,<br />
environmental justice, and concerns for increased noise and air pollution in addition to assessing the<br />
liability <strong>of</strong> acquiring potentially contaminated property and the proper management <strong>of</strong> contaminated<br />
soils and groundwater generated as part <strong>of</strong> the ESA process or during the construction <strong>of</strong> the project.<br />
