Synopsis:  Complex MGP Site Remediation in an Urban Setting - A Case Study

This case study is a presentation of a unique and complex MGP Site soil remediation project conducted by ERM in downtown San Rafael, California between 2014 and 2017. Elevated benzene and naphthalene concentrations and the urban setting led to extensive air modeling to complete
permitting, and required mitigation strategies including deployment of a large MaHaffey tent equipped with air treatment units. The further complicating implementation, the project was also subject to strict CEQA limitations for waste transport by truck, and waste was transported to four different non-hazardous waste landfills and two non-RCRA hazardous waste landfills.

Key Elements:

  • Extensive site prep
  • Excavation of over 30,000 cubic yards for offsite disposal
  • Excavations as deep as 25 feet to remove historical gas vessels
  • Strict air monitoring program to ensure public safety
  • Shoring and modified excavation technology to protect surrounding structures
  • Extensive Community Outreach and local hiring
