business days from "Notice to Proceed".

1.1.2. The purpose of a Phase I ESA is to identify and define
recognized environmental conditions within the range of
contaminants within the scope of the Comprehensive
Environmental Response, Compensation, and Liability Act
(CERCLA) and petroleum products. As such, the Phase I ESA
satisfies one of the requirements to qualify for the
innocent Companydefense to CERCLA liability: that is, the
practices that constitute "all appropriate inquiry into the
previous Ownership and uses of the property consistent with
good commercial or customary practice," as defined in 42 USC
9601(35)(B). The ESAs will be conducted in accordance with
American Society for Testing and Materials (ASTM) Standard:
E 1527-94 Practice for Environmental Site Assessments for
Commercial Real Estate, and will consist of four components:
records review, site reconnaissance, interviews, and a Phase
I report. In addition, the Federal Communication
Commission's (FCC) checklist for the National Environmental
Policy Act (NEPA) will be completed as part of the Phase I
ESA report. Each of the Phase I ESA components is discussed
in the following subsections.

1.1.3. Records Review

1.1.3.1. The record review will include a review of
environmental databases, physical setting sources,
and historical use information. The environmental
database search will include both federal and
state databases to ASTM-specified radii of the
site. Databases will include the National
Priorities List; the Comprehensive Environmental
Response, Compensation, and Liability Information
System (CERCLIS); Resource Conservation and
Recovery Information System (RCRIS) treatment,
storage and disposal facilities and generators;
Emergency Response Notification System; state list
of hazardous waste sites; state landfill and/or
solid waste disposal sites; state leaking
underground storage tank sites (USTs); and state
registered USTS. A current U.S. Geological Survey
(USGS) 7.5 minute topographic map will be obtained
for the area in which the property is located to
evaluate the physical setting. USGS or state
ground water and geological maps may be obtained
in some instances to provide further information.
Historical use

information will be obtained from the present to
the property's first developed use or to 1940,
whichever is earlier. Historical sources to be
reviewed may include aerial photographs, fire
insurance maps, property tax files, recorded land
title records, USGS maps, local street
directories, building department records, and
zoning and land use records. In addition, records
will be reviewed to determine designated
wilderness areas or preserve, threatened or
endangered species, Indian religious sites, flood
plains, wetlands, and zoning for high intensity
white lights under the National Environmental
Policy Act.

1.1.4. Site Reconnaissance
-------------------

1.1.4.1. A site reconnaissance will be conducted to obtain
information indicating the likelihood of
identifying recognized environmental conditions in
connection with the property. An environmental
professional will visit the site and visually and
physically observe the property and any structures
on the property. The interiors of any structures
will be inspected. The methodology used and any
limitations to the observations will be
documented. Uses and conditions to be evaluated
include current and past use of the property and
adjoining properties and surrounding area;
geologic, hydrogeologic, hydrologic, and
topographic conditions; structures; roads; potable
water supply; sewage disposal; hazardous
substances to include asbestos and petroleum
products; storage tanks; odors; pools of liquid;
drums; containers; polychlorinated biphenyls
(PCBs); heating/cooling; stains or corrosion;
drains and sumps; pits, ponds, or lagoons; stained
soil or pavement; stressed vegetation; solid
waste; waste water; xxxxx; and septic systems. In
addition, threatened or endangered species, and
wetlands will be identified during the site
reconnaissance.

1.1.5. Interviews
------------------

1.1.5.1. An environmental professional will conduct
interviews with the property owner and occupants
and local government officials to obtain
information indicating recognized environmental
conditions in connection with the property. The
information sought during the interviews will be
the same as the uses and conditions to be observed
during the site reconnaissance. The transaction
screen questionnaire in ASTM Standard E 1528-93
Environmental Site Assessments: Transaction Screen
Process will be used during the interviews. Prior
to the site visit the property owner, site
manager, or user will be contacted to obtain any
helpful documents, such as environmental audit
reports, environmental permits, registrations for
storage tanks, hydrogeological or geotechnical
studies, etc. Local agency officials to be
contacted may include the fire department, public
health department, etc.
