- Document Description
- DTSC has approved a draft Removal Action Work Plan (RAW) for the Osage Inc. 60th Street West Site. The RAW summarizes the findings of site investigation activities, identifies Chemicals of Concern (COCs), assesses risk for the purposes of determining the need for remedial action and identifying appropriate cleanup goals, and defines the extent of environmental media which must be managed in order to protect human health and the environment. The RAW then evaluates removal action alternatives and selects the alternative that best meets the criteria of effectiveness, implementability and costs as required under applicable law, regulation and guidance. The alternative selected for implementation at the Site consists of the excavation and off-site disposal of contaminated soil and use of administrative controls (deed restriction) in a manner that will allow for future industrial/commercial use of the Site, but not sensitive uses such as residences, schools or hospitals. The risk assessment in the DTSC approved Remedial Investigation and Feasibility Study determined the COCs identified in the RAW as follows: arsenic, cadmium, lead, dioxin, and furans.

Notice of Exemption
- Exempt Status
- Type, Section or Code
- Section 15061(b)(3)
- Reasons for Exemption
- Although the Site is on the Hazardous Waste and Substances Sites List compiled pursuant to Government Code section 65262.5 dated January 1990, DTSC has determined that there is no possibility of a significant environmental effect from the project as described above because: 1. The project will serve to restore the Site and to reduce the environmental and human health risk impact caused by the Site conditions by the removal and offsite disposal of contaminated soil. This will serve to eliminate unacceptable exposures to contaminated soil, eliminate the potential for contaminants to impact groundwater, and will effectively remove the potential for offsite contaminated soil, eliminate the potential for contaminants to impact groundwater, and will effectively remove the potential for offsite contaminant migration. The project is in a developed commercial, industrially-zoned area and will not affect any known sensitive biological habitat or cultural resource area. 2. A Rarefind report for the Rosamond and Rosamond Lake quadrants dated December 12, 2005 did not identify the presence of sensitive species at the Site and the surrounding vicinity. The Site is not located in an area of sensitive ecological receptors, or cultural resources based on a review of maps, databases, and a screening field survey. 3. A cultural records search through the Southern San Joaquin Valley Archaeological Information Center (SSJVAIC) was conducted to identify recorded cultural resources within a one-half and one mile radius of the site. The search involved researching for sites within the Rosamond, Little Butte, Willow Springs and Soledad Mountain 7.5 Minute Quadrangles. 4. The remediation contractor will identify and confirm the location of underground utilities prior to the start of work. 5. DTSC has conducted or overseen at least a half dozen projects involving the onsite consolidation and/or capping of metal and dioxin contaminated soils in the Rosamond and nearby Mohave areas over the past 15-18 years. Each of these projects has resulted in the betterment of the environment without creating any adverse impacts either individually or cumulatively. DTSC has not observed any significant environmental effect resulting from the implementation of any of these projects.
