Vine Hill Properties LLC owned and IT Corporation (IT operated the
Vine Hill Complex (VHC) Class I Hazardous Waste Management Facility. IT is
hereinafter referred to as the Discharger. The VHC consists of two properties (sites)
separated by Pacheco Creek. The sites are referred to individually as the Vine Hill site
and the Baker site. The VHC is situated close to the intersection of Interstate 680 and
California State Highway 4, just east of the City of Martinez as shown in Figure l.
The 40-acre Vine Hill site is located at 896 Waterbird Way, Martinez, California,
northwest of Pacheco Creek. Access to the Vine Hill site is obtained via Waterbird Way
at the western portion of the site. The Baker site originally covered approximately 130
acres of the VHC and is located at 5030 Imhoff Drive, Martinez, California, between
Pacheco Creek and Walnut Creek. Following the completion of closure activities, the
Baker site now consists of a landfilt (Baker landfill) and support facilities that take up
approximately 26 acres on a 30-acre parcel.
The Vine Hill site is bounded on three sides by property owned by Acme Fill
Corporation. The Martinez Gun Club is located adjacent to the southern boundary. The
Baker site was originally bounded by IT land holdings to the south and north, however
these properties were sold to U.S. Development in late 2001 and Gonsalves & Santucci,
Inc. in 2002. None of the adjacent property is currently developed or being utilized for
commercial/industrial purposes.
The Baker site included 7 surface impoundments covering a total of over 110 acres.
During closure, all wastes and contaminated subsoils were excavated and placed in an
onsite consolidation landfill of approximately 26 acres. As with Vine Hill site, the Baker
landfill is also completely contained by a subsurface slurry wall. A perimeter
groundwater collection trench extends around the Baker landfill and inside this
containment wall removing groundwater impaired by waste. Recovered groundwater is
transferred via pipeline to the Vine Hill evaporation basin. Results of an intensive testing
of subsoils both prior to and after excavation were utilized to verify that cleanup
objectives had been met in all areas other than the consolidation landfill. Following
DTSC approval of cleanup activities in December of 1998, the excavation areas were
backfilled with clean inert fiIl.
