ENVIRONMENTAL DISCLOSURE MEMO FOR RELINQUISHMENT 56135
This memo presents an assessment of known or likely hazardous material- and waste-related concerns pertaining to relinquishment 56135 located along Interstate 880 at postmile 27.8 in the city of Oakland.
Site Description
Relinquishment 56135 consists of an approximately 34,000-square-foot parcel as identified on the attached drawing (Attachment 2, right of way relinquishment map).
See Attachment 1 for a site location map.
Current Site Use
The site is largely a local road, Oakport Street, and a partially paved median-type area between Oakport Street and East 8th Street.
Use Prior to Acquisition by Caltrans
Historic aerial photos indicate that the relinquishment parcel was first developed at some point between 1946 and 1958 as a local road/freeway off-ramp (Oakport Street) and a small portion of Alameda Avenue. The roadway layout has been largely unchanged since then.
Utility Easements and Pipelines
A review of Caltrans records indicates that there is one easement for the parcel: a
19.7-foot-wide easement for utilities and maintenance purposes reserved by the state of California. See Attachment 2 for details.
GeoTracker and EnviroStor Data
The regulatory databases GeoTracker and EnviroStor are maintained by the California State Water Resources Control Board and the California Department of "Provide a safe and reliable transportation network that serves all people and respects the environment"

Caltrans, on September 8, 2022, reviewed these regulatory databases and identified eight locations (six different sites) of regulated properties within approximately 500 feet of the relinquishment area.

Aerially Deposited Lead
Tetraethyl lead was first added to gasoline, as an anti-knock additive, in the early 1920s. California ended the use of leaded fuel for any on-road motor vehicles in 1994, with the remainder of the United States banning use in 1996. Lead is still an additive to aviation fuels. Particulate lead was discharged in vehicle exhaust, settling on and along California’s highways. The lead discharged from motor vehicles that accumulated in roadside soil is referred to as aerially deposited lead (ADL). Elevated concentrations of ADL are present in roadside soils throughout California.
Due the use history of the relinquishment area and surrounding area, ADL may be present within the area to be relinquished. Caltrans did not sample for ADL in the relinquishment area. Excavated soil with elevated ADL concentrations must be appropriately managed.

“Provide a safe and reliable transportation network that serves all people and respects the environment” Striping/Pavement Markings
Lead chromate was a constituent of striping paint and pavement marking materials but has been phased out by Caltrans. However, older striping and pavement marking materials having elevated concentration of lead may still be present.
Caltrans did not test these materials to determine if they contain lead chromate.
These materials must be appropriately managed if they contain elevated lead chromate.
California Geologic Survey Mineral Hazard Database Review The California Geologic Survey has compiled maps identifying mineral hazards within California, including petroleum, lithologic units and structures containing naturally occurring asbestos, mercury, asbestos, and other mineral hazards.
These maps indicate that the relinquishment area is not located within a geologic unit known to contain naturally occurring asbestos or other hazardous minerals.
There are no faults mapped on the CGS maps within the relinquishment areas where naturally occurring asbestos may be present on the slip faces.
There are no known gas wells, oil wells, or seeps identified on the Division of Oil, Gas, and Geothermal Resources (DOGGR) maps within or adjacent to the relinquishment area.
Chemically Treated Wood
Wood products, such as sign posts, are commonly treated with chemical preservatives to protect the wood from insects, microorganisms, fungi, and other environmental conditions that can cause wood decay. Treated wood contains elevated concentrations of hazardous chemicals. Once these wood products are removed from service they must be managed under Health & Safety Code §25230 et seq.
Based upon visual survey of the relinquishment area by Google Earth Street View imagery, wooden sign posts may be present within the area to be relinquished.
Spills and Accidental Releases
The Caltrans Maintenance program has no records of spills or accidental releases of hazardous materials within the area of relinquishment.
Visual Observations
Caltrans conducted a visual survey of the relinquishment area by Google Earth Street View imagery and did identify hazardous material and commercial uses adjacent to the relinquishment area located at:
1. Express Oil Change - 569 Howard Street, Oakland

2. Coliseum Sandblasting - 4356 Coliseum Way, Oakland
I
t is unknown whether the identified operations adjacent to the relinquishment area have released hazardous materials that could have entered the parcel being relinquished.
Electronic Waste
Caltrans has installed electronic systems or devices within the relinquishment area, including fluorescent lights, solar panels, electronic controllers, circuit boards, ballasts containing polychlorinated biphenyls (PCBs), et cetera, that are considered electronic waste when removed. These materials must be properly managed when removed for disposal.
