Site Cleanup Subaccount Program
CATEGORY OF SERVICE:
Helping our clients to receive fund remediation through the Site Cleanup Subaccount Program (SCAP) of the California State Water Resources Control Board.
TYPE OF CLIENT:
Private parties that are responsible for remediating contaminated properties, such as dry cleaners, industrial facilities, etc. The SCAP is a funding mechanism for responsible parties who lack sufficient financial resources to pay for the required investigation or cleanup of the existing or threatened surface or groundwater contamination.
The Site Cleanup Subaccount Program (SCAP) is a funding program established by Senate Bill 445 (Hill, 2014), allowing the State Water Resources Control Board to issue grants to fund projects that remediate the harm or threat of harm to human health, safety, or the environment caused by existing or threatened surface water or groundwater contamination. The evaluation process includes consideration of the degree of threat, whether the site is located in a small or disadvantaged community, the cost and benefits of the cleanup, and the financial resources of the responsible parties.
The owner of project location where surface or groundwater contamination occurred is financially responsible for cleanup. The SCAP can provide funding for the cost of the investigation and the cleanup.
- Trinity submits a complete Groundwater Quality Funding Program Pre-Application via Financial Assistance Application Submittal Tool (FAAST).
- As the site evaluation proceeds through the SCAP process, Trinity provides support including scopes of work and cost estimates for State approval.
- Trinity works actively with the oversight agency to gain approval for the scope of work and costs, and participates on the contract negotiation.
- Trinity tracks the progress of reimbursement requests through the electronic submittal system. If additional documentation is requested, Trinity provides the information on behalf of the owner of the contaminated site.
- As the cleanup project proceeds, Trinity uploads reimbursement requests to the SCAP utilizing their electronic submittal procedure. The reimbursement requests typically cover progress payments.

Industrial Manufacturing Solvents - Assessment and Remediation, Santa Cruz, California
TYPE OF CLIENT:
Private Owner – Multi-Tenant Commercial Building
The site is a former retail display manufacturing and metal plating facility and has been subject to environmental assessment and remediation for many years. A plume of dissolved halogenated volatile organic compounds (HVOCs) with 1,4-dioxane has been identified in groundwater beneath the existing industrial building, and multiple remediation events in various portions of the plume have been performed. The remediation activities by previous consultants have included subsurface injections of RegenOx, 3DMe, hydrogen-releasing compound, and persulfate with sodium hydroxide activator, at various times and locations. These remedial efforts have not effectively reduced the dissolved contaminant plume concentrations beneath the building, as significantly elevated HVOC concentrations remain in groundwater monitoring wells.
CLIENT GOALS FOR PROJECT:
The client required assistance to assess soil and groundwater data gaps and perform additional remediation to clean up the dissolved contaminant plume in order to achieve site closure from the Central Coast Regional Water Quality Control Board (CCRWQCB).
The site is considered to be a candidate for thermal remediation with soil vapor extraction to remediate the residual dissolved plume. The environmental work was estimated to cost more than three million dollars and was contingent upon the client receiving additional funding. With Trinity’s assistance, the client applied for funds through the State of California Site Cleanup Subaccount Program (SCAP). The SCAP allows the State Water Resources Control Board to issue grants to fund projects for responsible parties who lack sufficient financial resources to pay for the required environmental investigation and remediation. The client received grant approval from SCAP, and Trinity is currently conducting the data gaps assessment and remedial design.

- Conduct soil vapor delineation.
- Conduct subsurface assessment activities utilizing Membrane-Interface Probe (MIP) to determine the three-dimensional extent and mass of HVOCs and 1,4-dioxane in soil and groundwater, and confirm the depth and configuration of bedrock surface beneath the site.
- Prepare a Remedial Action Plan (RAP) proposing thermal remediation with soil vapor extraction to remove HVOCs and 1,4-dioxane from soil, groundwater, and soil vapor.
- Upon CCRWQCB approval of the RAP, complete system installation, and operate system for six months or more as needed to achieve remedial goals.
- Perform post-remediation confirmation sampling and groundwater monitoring to verify the effectiveness of the remedial effort to the satisfaction of the client and the CCRWQCB.
- Continue groundwater monitoring of plume.
- Complete site assessment to close data gaps.
- Prepare a request for proposal to obtain competitive bids for the thermal remediation
- Establish proposed cleanup goals for site chemicals of concern
- Prepare a Remedial Action Plan.
- Oversee construction, operation, and maintenance of the thermal remediation system
- Track progress of SCAP reimbursements throughout duration of environmental work.
