ACDEH Releases Updated VIMS Decision Matrix in 2021

In May 2021, Alameda County Department of Environmental Health (ACDEH) issued an updated decision matrix for the design of vapor intrusion mitigation and migration controls. The updated decision matrix helps the ACDEH select the redundancy for engineering controls and contingency controls — thereby helping Pangea determine what steps to take to address vapor intrusion.

New State Funding for Chlorinated Solvents and More

In 2015, a Site Cleanup Subaccount Program (SCAP) was created by California Senate Bill 445 and administered by the State Water Resources Control Board. The SCAP program provides funding (grant/reimbursement money) for investigation and remediation of impacted groundwater cases. Application evaluation criteria focuses on degree of potential human health and environmental impacts for small or financially disadvantaged communities. This is a new and evolving program for which Pangea has applied for funding for several of our clients. Contact Pangea to see if your project may qualify.

Underground Storage Tank (UST) Cleanup Fund Extended to 2026

In 2014, the passage of California Senate Bill 445 extended the Underground Storage Tank (UST) Cleanup Fund until January 1, 2026. The bill provided additional funding and also required the removal of single-walled USTs by January 1, 2026. Pangea President & Principal Engineer Bob Clark-Riddell assisted with bill support as the Vice President of CORE Environmental, Inc, a non-profit organization.

Vapor Intrusion Mitigation Systems (VIMS) Gain Prominence

Recently, vapor intrusion concerns are a primary driving force for site cleanup for our clients’ development projects and dry cleaner/solvent sites. Pangea has designed and certified installation of VIMS systems to facilitate building occupancy, safeguard human health, and facilitate regulatory case closure.
