Document Description
The Department of Toxic Substances Control (DTSC) is proposing to approve a Remedial Action Plan (RAP) for the Former Napa-1 Manufactured Gas Plant (MGP) Site (Site) located at 201, 211, 221, 241, 251 and 267 Riverside Drive, Napa, California pursuant to regulatory authority granted under Chapter 6.8, Division 20, sections 25323.1 and 25356.1, California Health and Safety Code (H&SC). The Draft RAP addresses impacts to soil and groundwater from previous operations at the Site. The Site and surrounding areas have been separated into three operable units (OU) to facilitate remedial action planning, cleanup activities, post remedial action certification, and closure of the project. OU-1 includes the on-site area encompassing the current PG&E property and virtually all of the former Napa-1 MGP footprint. OU-2 is an offsite area that includes a portion of the Elm Street Townhomes property adjacent to the west of the Site. OU-3, also an off-site area, includes the Public right-of-way (ROW) along the Napa River including Riverside Drive, and the adjacent Riverside Park (upper river bank area) to the east of the Site.
