Subject: Preliminary Site
Investigations: Altamont Pass, California (ALT1)
16, 1999 AVES, an Affiliate of ATC Associates, Inc., performed
an initial site investigation in the Altamont Pass area.
The purpose of the investigation was to identify properties in
and around this study area that would meet the siting criteria
for an inter-basin transport site to be used during the CRPAQS
monitoring program. The SJVUAPCD’s Mr. Evan Shipp, and
the BAAQMD’s Mssrs. Jim Cordova and Gary Zoppo
accompanied AVES during the site visit. Their combined
knowledge and assistance during the visit is gratefully
instructed to identify, if available, three sites per selected
area that satisfied the siting criteria presented in Aerometric
Monitoring Program Plan for the California Regional PM2.5 /PM10
Air Quality Study (CRPAQS), specifically Section 8.

selection activities performed in the Altamont Pass study area.
proposed site is located approximately 100m west of the dead end
of Comstock Rd and is readily accessible off Intersate 580 using
the N. Flynn Rd exit. The site is located on the south
side of the freeway approximately 100 meters above the grade of
the freeway. The site is secure and has power and
telephone available. The transmission station is enclosed
by a cyclone fence with barbed wire. GTE apparently leases
the land from the landowner who resides at the farmhouse on the
north side of I-580 due north of the proposed site. The
farmhouse can be seen in photograph P6160016.
proposed site has 360° exposure and has additional space to set
a 10 meter met tower. Photographs P6160016 through
P6160020 show views from the GTE enclosure to the north, east,
south, west, and northeast (through the pass). There
appeared to be no signs of vandalism or suspicious activities at
the site and the land owner appears to keep a watchful eye on
sites UTM coordinate are N 37°43’05.2" and W121°
39’38.2". The GTE call sign is KNKA228, Tower ID is
1016788, and site number is CA0289.
Site 1- GTE MOBILENET
Emergency Number: (800) 621-2622
drive-by observations through the pass did not reveal any
additional sites that would meet the siting specifications
satisfied by the GTE site. A CalTrans met site was
identified, but was within 50 meters of I-580 at grade.
Other potential sites with power would be impacted by the
turbulence generated by the wind power generation systems
interspersed throughout the pass.
