2.4.1.2 Stations Segment
Contaminant Management Plan, SVRT/BART Extension
As described in Sections 2.2.1, 2.2.3, and 2.3.4, the design of the actual stations will reside with the segment
that they fall along (such as the Line Segment, Tunnel Segment, or Yard and Shop Segment). However, for
ease of reference, impacts to soil and ballast are summarized below for each station and/or corresponding
campus. With the exception of the portions of the three stations (future South Calaveras Station,
Montague/Capital Station, and Berryessa Station) that fall within the former UPRR right-of-way under the
Line Segment, there have been no previous environmental investigations performed on behalf of VTA at any
of the stations and corresponding campus areas. However, investigations are in the planning stages and are
expected to occur during the final design phase. The information provided below is generally based on
database searches summarized in the Final Environmental Impact Report (Final EIR) prepared by VTA, or as
otherwise indicated.
Future South Calaveras Station, Montague/Capitol Station and Campus, and Berryessa Station and Campus
The most significant hazardous materials at these station and campus areas are believed to be the impacted
soil and ballast along the former UPRR tracks within the Line Segment, as described in Section 2.4.1.1. Based
on the prior investigations within the former UPRR ROW, there are significant levels of arsenic and lead in
soil and ballast along the former UPRR right-of-way, including the portion that passes through the station
campuses.
Alum Rock Station and Campus
The database search summarized in the Final EIR identified a number of sites with hazardous materials
releases on or near the Alum Rock Station campus. Most of these sites involve petroleum hydrocarbons such
as gasoline or diesel releases from underground fuel storage tanks into soil and/or groundwater. At least three
of these sites are located on the station campus. Although these sites have obtained regulatory agency case
closure, this does not imply that no contamination from these sites will be encountered during construction.
The sites include the following:
• Monarch Truck Center, a truck rental, leasing and repair company at 195 North 30th Street. Monarch
Truck Center released moderate levels of petroleum hydrocarbons to soil and groundwater.
• Mission Concrete Products, at 125 North 30th Street (partially the location of the future transit
oriented development), which released moderate levels of petroleum hydrocarbons to soil and
groundwater.
• Security Contractor Services, at 170 North 28th Street (partially the location of the future transit
oriented development), which released petroleum hydrocarbons to soil.
