Document Description
Notes: Response to Comments The DTSC pursuant to Ch. 6.5, Division 20, Section 25355(a)(1) of the Health and Safety Code approved the Remedial Action Plan, Ramirez Street Area, Former Aliso MGP, LA, CA, Tetra Tech, March 2016 (RAP or "the project"), which is incorporated by reference. The project or RAP is for the remediation of a portion of Ramirez Street (a public street) located in Downtown LA between Center and Keller streets (referred to as the "Ramirez Street Area" or the "Site"). The Southern CA Gas Company (SoCalGas) sponsored the environmental cleanup of the Ramirez Street Area based on a Voluntary Cleanup Agreement (VCA) [Docket No. HSA-A-00/01-173] executed between the DTSC and SoCalGas dated January 19, 2001. The RAP for the Site serves to remove the contaminated soil by excavation and transport it to a treatment/recycling facility and restore the Site as a street, its current use. The RAP for the Site will be limited to an area approx. 500 feet long 70 feet wide, with a maximum depth of 30 feet. The soil contamination, in part, due to past manufactured gas plant (MGP) and butadiene (the raw material for manufacturing of rubber) operations. contaminants include benzene, naphthalene, polycyclic aromatic hydrocarbons (PAHs), total petroleum hydrcarbons (TPHs), and dicyclopentadiene (DCPD). The project includes removal of contaminated soil in accordance with the methods and procedures presented in the RAP and in the Remedial Design document to be prepared prior to implementing remedial activities.
