Industry: Gas Station/ Underground Storage Tank Owners

Since 1989 The Reynolds Group has been helping gas station owners assess and remediate the soil and groundwater contamination at their sites, receiving Closure (No Further Action) letters from regulators for hundreds of cases. The Reynolds Group removed thousands of UST's in the 1990's leading to a significant backlog of assessment and remediation cases. In addition, The Reynolds Group continues to take on new cases as the demand for competent, ethical, and proactive consulting services has grown.

The Reynolds Group provides a complimentary initial review by a principal in the firm, of any gas station situation, question, or technical report.Many gas station owners do not know the next steps in advancing their cases and the Reynolds Group can provide such direction. The Reynolds Group is also very familiar with State Leaking Underground Storage Tank Funds (such as the California State Clean-Up Fund)and can assist or direct clients towards seeking reimbursement of their assessment and remediation costs.

The Reynolds Group has provided UST assessment and remediation services under the regulatory auspices of the Federal Environmental Protection Agency (EPA), the California Environmental Protection Agency (Cal EPA), the California Department of Toxic Substances Control (DTSC), the California State Water Resources Control Board (through the nine Regional Water Quality Control Boards), as well as a variety of county and city fire departments and environmental health care agencies.

The Reynolds Group is capable of providing turnkey services including permitting, assessment, pilot testing, remediation, operations and maintenance, groundwater monitoring, and financing. The Reynolds Group pushes projects forward from start to "No Further Action."TRG staff are very comfortable interacting with city officials, regulators, attorneys, property owners and tenants, to ensure that all parties are satisfed and projects stay on track.

MTBE Remediation (6111)

Client:	STRAUB DISTRIBUTING
Proj Mgr:	Angel Cardoza	Completed:	09/13/2002
Industry:	Gas Station/ Underground Storage Tank Owners	Service:	Mtbe Remediation
One of Californias major beverage distributors engaged TRG to close all fueling facilities in its Southern California locations. One site in particular had widespread gasoline and MTBE contamination in the soils and groundwater across a wide area, including the surrounding neighborhood. After fully characterizing the extent and spread of the groundwater contamination throughout the neighborhood, TRG designed, permitted, constructed and operated an air sparging and soil vapor extraction system that significantly reduced the plume size. The Reynolds Group demonstrated that conditions in the soils beneath the site were sufficient for natural attenuation to degrade the remaining low amounts of gasoline, and site closure was granted in 2002.

Service Station Soil/Groundwater Clean Up (5299.VII)

Client:	GREENWOOD
Proj Mgr:	Dwayne Ziegler	Completed:	08/06/2010
Industry:	Gas Station/ Underground Storage Tank Owners	Service:	Mtbe Remediation Soil Vapor Extraction Groundwater Remediation Operations And Maintenance Of Remediation Systems
This case involves gasoline (BTEX and MTBE) impact to soil beneath the site and groundwater beneath and off site. Site assessment was accomplished with a network of 12 groundwater monitoring wells distributed across the site, in city streets and on neighboring properties. The site is located very near the City of Tustin drinking water wells. The gasoline plume extended 80 feet to groundwater. Remediation was accomplished with the installation and operation of soil vapor extraction and groundwater pump and treat systems. Because of the predominately sandy soil matrix at the site, the soil and groundwater cleanup was accomplished with a system of four soil vapor extraction wells and three pumping wells. Active remediation of the 80 foot deep soil plume and groundwater contamination was accomplished in four years. Closure was received from the Orange County Health Care Agency.

Soil Vapor Extraction and Air Sparge (5672)

Client:	ARCO POWER GAS
Proj Mgr:	Dwayne Ziegler	Completed:	08/05/2009
Industry:	Gas Station/ Underground Storage Tank Owners	Service:	Mtbe Remediation Operations And Maintenance Of Remediation Systems
TRG manages the cleanup of three sites for this client. This is the second of the three to achieve closure. Following complete assessment of gasoline impact in soil and groundwater on and off site, a soil vapor extraction and air sparge system was installed and operated at the site. The remediation system employed at the site consisted of 12 air sparge wells connected to a sparge blower and 16 vapor extraction wells connected to an all-electric catalytic oxidizer. Over the course of 18 months of operation, the technician assigned to the project ensured that the project team received relevant and necessary data to analyze the progress of the cleanup and adjust the operational strategy at the site. The technician also ensured the remediation system was operational well over 90% of the time. Following 12 months of post remediation groundwater monitoring, the site was closed by the Los Angeles Regional Water Quality Control Board. TRGs operations and maintenance group is a key component to implementing strategies that lead to site closures.

Injection and Monitoring (5671)

Client:	ARCO POWER GAS
Proj Mgr:	Dwayne Ziegler	Completed:	08/27/2007
Industry:	Gas Station/ Underground Storage Tank Owners	Service:	Regulatory Response & Negotiation Mtbe Remediation Groundwater Monitoring Groundwater Remediation
Located on the border of Los Angeles and Culver City, this site lies within the Charnock sub-basin, from which the City of Santa Monica has historically obtained drinking water. The City's production wells in the Charnock sub-basin were shut down in 1996 when MtBE was discovered to have impacted the deep aquifer. Because of its location within the Charnock sub-basin, strict scrutiny was applied to this site by the Los Angeles Regional Water Quality Board, the US EPA and the City of Santa Monica. The gasoline released at this site had impacted the groundwater. The gasoline plume was assessed with a network of 15 groundwater monitoring wells. The remedial approach consisted of air sparging, soil vapor extraction and injection of a chemical oxidant to "polish" the groundwater concentrations and achieve the stringent closure concentrations. Closure was granted by the Los Angeles Regional Water Quality Control Board. The Reynolds Group provided Cleanup Fund approved assessment and remediation services for this project.

Gasoline Plume (6961.VII)

Client:	CITY OF COACHELLA
Proj Mgr:	Sarah Pearcy	Completed:	In Progress
Industry:	Gas Station/ Underground Storage Tank Owners	Service:	Soil Remediation Regulatory Response & Negotiation Soil Vapor Extraction Site Assessment Groundwater Remediation California Cleanup Fund
This project is ongoing and funded by the Emergency, Abandoned, and Recalcitrant (EAR) Account which is administered by the Cleanup Fund. TRG has assessed the gasoline plumes in soil and groundwater (which extends off-site across a city street and beneath neighboring properties), installed soil vapor extraction and air sparge systems and begun active remediation. The core of the groundwater and soil plumes have been cleaned up. Semi-annual groundwater monitoring takes place through a network of 11 groundwater monitoring wells. An MTBE cut off plume remains to be cleaned up. The next phase of the project envisions the installation of six off-site ozone sparge wells to address the plume in the groundwater that has traveled off-site. Additionally, to ensure an even greater impact on the overall project, TRG has coordinated efforts between the regulator on the case and the Clean-up Fund contact to lay out project plans and budgets on an annual basis thereby compressing the typical time-line of a project like this. Our client is kept up to date with every aspect of the project. Closure is expected from the Colorado River Basin Regional Water Quality Control Board within two years.

Case Closure in San Diego (7306.VII)

Client:	SWALL FINANCIAL SERVICES
Proj Mgr:	Al Fuan	Completed:	05/16/2011
Industry:	Gas Station/ Underground Storage Tank Owners	Service:	California Cleanup Fund Regulatory Response & Negotiation Site Assessment
TRGs client had an open case at the San Diego Site Assessment/Mitigation Unit since 1991. When TRG was contracted as the environmental consultant of record in 2008, the case had already been transferred to the San Diego Regional Water Quality Control Board (SDRWQCB). We helped our client gain access to the Underground Storage Tank Cleanup Fund (USTCF) which reimbursed them for previous costs associated with assessment and source removal. TRG then completed the assessment of the contamination at the site and aggressively pursued case closure from the SDRWQCB arguing there was no need for active cleanup at the site. In less than two and a half years, TRG was able to obtain funding and close a case that had lingered for well over a decade. All work performed by TRG was within USTCF cost guidelines and was fully reimbursed by the USTCF. In less than two and a half years, TRG was able to obtain funding and close a case that had lingered for well over a decade.

Remediation at Gas Station Site (6122.CUF)

Client:	MAGIC GAS
Proj Mgr:	Al Fuan	Completed:	11/23/2010
Industry:	Gas Station/ Underground Storage Tank Owners	Service:	Soil Remediation Soil Vapor Extraction Health Risk Assessments California Cleanup Fund
When The Reynolds Group was brought onto this project in the Echo Park neighborhood of Los Angeles, the soil and groundwater contamination had not been fully assessed. The site was, therefore, not eligible for closure consideration. We assisted our client with their Cleanup Fund application and secured funding for the project. Once funding was in place, the cost of all subsequent work was pre-approved by the Cleanup Fund in order to guarantee reimbursement of costs, and the contamination was fully assessed. Upon completion of the assessment, TRG performed a limited amount of soil remediation and demonstrated the groundwater plume was stable (not increasing or spreading in area). Results of soil vapor sampling and a Human Health Risk Analysis (HHRA) demonstrated there was no risk of detrimental effects to human health by way of gasoline vapor intrusion.
