updated phase i and limited phase ii environmental site assessment

1.0 INTRODUCTION
1.1 PURPOSE
URS Corporation (URS) was retained by the City of San José (City) to conduct a Phase I and Limited
Phase II Environmental Site Assessment (ESA) for the Mineta San José International Airport –
The West Side Parking Lot, 1120 Coleman Avenue, and 1128 Coleman Avenue are located at Norman Y.
Mineta San José International Airport (SJIA) in the City of San José, Santa Clara County, California
(subject properties or Sites) (see Figure 1). The purpose of this Phase I and Limited Phase II ESA was to
review past and present land use practices and current site conditions to evaluate potential environmental
impacts and to identify recognized environmental conditions (RECs) at the subject properties, including
potential impacts from known environmental problems in the surrounding area. The term “recognized
environmental conditions,” as defined by ASTM Designation E 1527-05, means:
“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 of any hazardous substances or petroleum products into structures of the
property or into the ground, ground water, or surface water of the property. The term
includes hazardous substances or petroleum products even under conditions in compliance
with laws. The term is not intended to include de minimis conditions that generally do not
present a material risk of harm to public health or the environment and that generally would
not be the subject of an enforcement action if brought to the attention of appropriate
governmental agencies. Conditions determined to be de minimis are not recognized
environmental conditions.”
The Phase I ESA was performed in conformance with the ASTM Standard Practice for Environmental
Site Assessments (Standard E 1527-05) approved November 18, 2005 and the United States
Environmental Protection Agency’s standards for All Appropriate Inquiries (AAI). For the purpose of
this report, hazardous substances and petroleum products are jointly referred to as “hazardous materials.”
1.2 SCOPE OF SERVICES
The Phase I ESA was accomplished by, and limited to, a reconnaissance of the Sites, interviews with site
representatives, a visual reconnaissance of the site vicinity, and review of agency databases and other
reasonably ascertainable information regarding past and current land use for indications of the
manufacture, generation, use, storage and/or disposal of hazardous substances at the Sites. The Limited
Phase II ESA was accomplished by, and limited to, advancing four soil borings and collecting soil and
groundwater samples in the area of the former farm operations and waste oil tank identified in the
February 2012 Phase I ESA. Samples were analyzed to assess if waste oil or other associated compounds
are present in the subsurface.
The general scope of work for this Phase I and Limited Phase II ESA is outlined below. The Phase I and
Limited Phase II ESA were completed for the City in general accordance with URS’ proposals dated
December 5, 2011 and May 10, 2012. To meet the objective of this Phase I and Limited Phase II ESA,
URS completed the following tasks:
