“The 1598 Bay Site is within the larger Pacific Gas and Electric Former North Beach Manufactured Gas Plant Site (MGP) Site identified and managed as APN 0459007. As part of the PG&E Former North Beach MGP Site, PG&E in 2016 excavated and disposed of approximately 9,000 cubic yards of soil impacted with MGP-residues, primarily polycyclic aromatic hydrocarbons (PAHs). The Removal Action Completion report for PG&E North Beach MGP- APN 0459007 documents the soil removal by PG&E.
As part of redevelopment of the Site into a four-story residential building with a first floor parking garage, the property owner/developer (also under DTSC oversight), installed and conducted verification testing of a vapor mitigation system (VMS). The Site Management Plan Implementation Report for the 1598 Bay Site documents the installation and verification testing of the VMS.
Post-construction indoor air and outdoor air sampling has been conducted and has been demonstrated to be protective for future occupants. Contamination left in place is addressed with institutional controls in the form of a Land Use Covenant and Agreement between DTSC and the property owner. Long term operation and maintenance of the VMS is managed under the Verification, Operation, and Maintenance Plan and Operations and Maintenance Agreement.
