The Right-of-Way & Utilities Office is responsible for managing acquisition and offshoring activities in projects and programs supported at the federal or federal level. The Office also serves to identify and resolve supply conflicts that occur during the installation of municipal plants on highways. DTSC has entered into a binding agreement with the California Department of Transportation (Caltrans) for the management of contaminated soils (ADL) deposited in the air, which are dismantled by Caltrans as part of highway improvement projects (agreement). From 1996 to 30 June 2016, these activities were covered by a derogation from certain hazardous waste laws. In July 2015, DTSC decided to move from a waiver of this new agreement to ensure the protection of human health and the environment. The agreement provides that all soils contaminated with ADL are properly managed by Caltrans, with a lead concentration above its full use (currently 80 mg/kg). The agreement will apply from 1 July 2016 to existing and new Caltrans projects. The variance, which previously covered the management of ADL-contaminated soils excavated as part of Caltrans motorway improvement projects, ended on June 30, 2016. The management activities to which this Agreement generally applies are the storage, disposal, monitoring, transport and final placement of ADL-contaminated soils. DTSC will monitor compliance with the agreement and monitor highway improvement projects that reuse ADL-contaminated soils. It will also serve as a resource for public and local authorities acquiring the right of navigation for federal projects.
