The property, acquired by a non-profit dance studio in South Central Los Angeles, was found to be impacted by gasoline from former Underground Storage Tanks (USTs). Concerns about property value and health risks lead the property owner to obtain a Brownfield Grant. TRG was selected to advance remediation work under the oversight of the United States Environmental Protection Agency (USEPA), the Community Redevelopment Agency of the City of Los Angeles (CRA/LA), and the City of Los Angeles Fire Department (LAFD). After successful cleanup activities and health risk assessments, case closure is being negotiated for the property.

32 Manufacturing Sites in Mexico (Two Week Turnaround) (6731.XI)

Client:	CONFIDENTIAL MAJOR NEW YORK INVESTMENT BANK
Proj Mgr:	Daniel Nunez	Completed:	09/01/2004
Industry:	Mexico (latin America) Businesses Manufacturers	Service:	Real Estate Due Diligence And Transaction Support
The Reynolds Group (TRG) performed 32 Phase I Environmental Site Assessments and Priority Ranking Studies in the country of Mexico. The engagement required rapidly accessing critical environmental information, performing site inspections around the country, interviewing key personnel and providing an immediate priority ranking of potential environmental concerns. These concerns were identified at the 32 manufacturing plants that were involved in a highly confidential acquisition. The engagement dealt with heavy industrial manufacturing sites, some of which were two miles square in area. TRG was able to mobilize to ten different states in Mexico and rapidly access critical environmental information by performing site inspections and interviewing key personnel. With this information, TRG provided the client with frequent updates and finally a priority ranking of the 32 manufacturing plants. TRG coordinated with the fast-moving Fortune 500 client, conducting extensive research and interviews to acquire difficult to obtain information for a large number of sites. At the completion of the project, TRG completed a summary of the findings in an eyechart, a user-friendly format that highlighted the risks and environmental concerns at each site. TRG has maintained a presence in Mexico for nearly 12 years and performs more than 300 due diligence studies per year.

Groundwater Monitoring (5542)

Client:	BARTHELEMY DAIRY
Proj Mgr:	Daniel Nunez	Completed:	In Progress
Industry:	Real Estate Managers/owners	Service:	Mtbe Remediation
The subject site is a dairy facility that once contained 7 single walled steel underground storage tanks (UST's) and dispensers that served fueling operations. In September 1998, two 8,000 gallon, two 6,000 gallon, one 3,000 gallon and two 450 gallon tanks that contained either diesel or gas were removed from the site by another contractor. In September 1998, analytical lab results suggested high concentrations of gasoline and diesel impacted soils beneath the northern most 450 gallon USTs and beneath the former, southernmost dispenser island. The project involved quarterly groundwater monitoring of 8 wells where the depth to groundwater was 42 feet. Concentrations of benzene ranged from non-detect (ND) to 12,032 parts per billion (ppb). Concentratons of MTBE ranged from ND to 7,161 ppb. The Reynolds Group interacted with the State of California Clean Up Fund to make sure all work was re-imbursable to the client.

MTBE Remediation (6009VIII)

Client:	CHRISTEL SHEARER
Proj Mgr:	Daniel Nunez	Completed:	05/31/2008
Industry:	Insurance Companies	Service:	Groundwater Remediation Operations And Maintenance Of Remediation Systems
This project in Riverside, California involved an insurance company policy that was called into effect. The insurance company, American International Group (AIG), paid for the client's attorney, paid for third party oversight of The Reynolds Group's work and was in-line to provide funding to the project over a certain limit. According to the Santa Ana Regional Water Quality Control Board's (SARWQCB) Ken Williams, The Reynolds Group removed more gasoline from the ground at this site than at all but two other cases he had worked on. Site assessment was accomplished with a network of 17 groundwater monitoring wells spread over an area 800 feet by 300 feet. The gasoline plume extended 100 feet to groundwater. Up to eight feet of free phase gasoline was discovered floating on the groundwater beneath the site. Remediation was accomplished with the installation and operation of free product recovery, soil vapor extraction and air sparge systems. Closure was obtained by working closely with the SARWQCB, understanding the detailed subsurface conditions, applying the most applicable remedial technology to the case and operating it efficiently.

Client:	GREENWOOD
Proj Mgr:	Daniel Nunez	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 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:	Daniel Nunez	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:	Daniel Nunez	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.

Industry:	Redevelopment Agencies City, County, State And Federal Agencies	Service:	Brownfields/redevelopment Underground Storage Tank Removals
TRG was chosen by the City of Coachella to assess and remediate groundwater contamination of an abandoned brownfield site. The funding for the assessment and cleanup activities is provided through the California Orphane Site Cleanup Fund Account. TRG has been coordinating efforts between, the City, the Colorado River Basin Regional Water Quality Control Board and the OSCF Account to continually advance the case toward closure. This coordination is crucial in changing this blighted property to a beneficial community asset. To date, TRG has fully assess the contaminant plumes on and off-site, cleaned up the source on-site and is coordinating with adjacent property owners to cleanup the off-site remnants of the contaminant plume.

Legal Services for a Car Wash (5316.I)

Client:	ENVIRONMENTAL ATTORNEY
Proj Mgr:	Daniel Nunez	Completed:	In Progress
Industry:	Attorneys	Service:	Litigation Support
The City of Santa Monica has had some of their drinking water wells shut down due to contamination. TRG's Santa Monica based client required multiple aspects of environmental legal services. In one aspect, TRG's client was being pursued by the U.S. EPA for having disposed de minimis wastes in a landfill that subsequently became designated as a Superfund site. The U. S. EPA sought reimbursement for large costs associated with the de minimus waste. TRG prepared technical historical documentation and the environmental attorney was able to resolve the matter in a de minimus manner. Concurrently, the City of Santa Monica threatened action against TRG's client for potential diminution of value due to a contamination emanating from its clients site onto the City of Santa Monica's property. Working with the environmental attorney The Reynolds Groups team was able to placate the City of Santa Monica's concerns.

SB989 Bona Fide Ground Tenant (7564.1)

Client:	ENVIRONMENTAL ATTORNEY
Proj Mgr:	Daniel Nunez	Completed:	09/30/2011
Industry:	Attorneys	Service:	Brownfields/redevelopment
One attorney The Reynolds Group has worked with was instrumental in creating SB989, The Bona Fide Ground Tenant concept. SB989 allows real estate transactions under a lease to own concept to test the property and remediate the contamination. An interested buyer can enter into a lease to develop a contaminated property with an option to buy. The development can be advanced, the property can be developed, and the resulting cash flow can be used to pay for remediation. This law indemnifies the developer from the sellers contamination. The Reynolds Group teamed with this environmental attorney to evaluate SB989 for a project in the Old Town Tustin redevelopment area and facilitated the real estate transaction for a retired couple who needed the property sold for retirement liquidity. In addition, The Reynolds Group has partnered to sponsor a White Paper for a joint DTSC/EPA Region 9 Solar Energy on Landfills and Contaminated Sites Initiative. The Reynolds Group remains close to the cutting edge of legislative activity in the Brownfield area that can match financing, credits or favorable Brownfield laws towards completing assessment and remediation.

Client:	CITY OF COACHELLA
Proj Mgr:	Daniel Nunez	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.

Proj Mgr:	Daniel Nunez	Completed:	In Progress
Industry:	Non-profit Organizations	Service:	Not Assigned
Our client is one of the most well regarded and well respected affordable housing developers in Los Angeles County. The firm came to us after a previous consultants inactivity had caused the project fall out of the regulators good graces. Once engaged, TRG contacted the regulatory agency and negotiated a minimal initial scope of work to bring the case back into compliance and laid out a plan to progress the project at a metered pace while searching for grant funding. TRG is working according to the strategy laid out upon our initial engagement.

Heavy Metals Contamination Cleanup (7637.X)

Client:	RICHLINE PROPERTIES
Proj Mgr:	Daniel Nunez	Completed:	08/23/2011
Industry:	Metal Finishers	Service:	Hexavalent Chromium Clean-up Mtbe Remediation
TRG assisted a property management company in the wrap up of a tenant lease in Beverly Hills. The former occupant operated a metal plating business in the leased space. As part of the wind down of the lease, the tenant was required to return the property to its original condition. The property manager had been working with another environmental consultant who had identified metals in the soil beneath the former plating operation. However, the property manager retained TRG to perform the cleanup of the property and obtain case closure from the Los Angeles County Fire Department HAZMAT Division. Concentrations of contaminants such as chromium, copper, lead, nickel and zinc in the soil exceeded allowable limits and necessitated the physical excavation of the soils in order to clean up the site. Unfortunately, the impacted soils were beneath the building and below a shallow basement. Approximately 50 cubic yards of soil needed to be dug up, manifested and properly disposed of. TRG was able to mobilized specialized equipment to the site in order to excavate the contamination from the basement level and load it into bins for transport to an appropriate disposal facility. Confirmation sampling showed pockets of contamination still in place after the initial excavation, and additional spot excavation was performed. TRG reported on the excavation activities which confirmed the metals at the site are now below concentrations negotiated with the County Fire Department. Case closure is eminent.

Phase II Environmental Site Assessment (7663.IV)

Proj Mgr:	Daniel Nunez	Completed:	03/17/2011
Industry:	City, County, State And Federal Agencies	Service:	Real Estate Due Diligence And Transaction Support Site Assessment
The Reynolds Group just successfully completed an environmental screening project with the Los Angeles County Metropolitan Transportation Authority (MTA). MTA is expanding light rail service to Santa Monica from Culver City with the Exposition Phase 2 Light Rail Transit Project (Expo Phase II LRT Project). Part of the project involves acquiring properties along the route. MTA was concerned about possible liabilties associated with the past and present uses of these properties. TRG won the project in a competitive bid process and performed subsurface soil sampling and analyses. The work was coordinated with the businesses operating at the sites and was performed with no interruption to their operations. MTA is completely satisfied with the work, and we are pleased to have them as our client.

Dry Cleaner Assessment (7564.VI)

Client:	PRIVATE PROPERTY OWNER
Proj Mgr:	Daniel Nunez	Completed:	09/30/2011
Industry:	Drycleaners Real Estate Managers/owners	Service:	Soil Vapor Extraction Health Risk Assessments Operations And Maintenance Of Remediation Systems Soil Remediation
The Reynolds Group recently completed a controversial assessment and remediation that involved Assessment, Health Risk Assessment and Remediation through the Orange County Health Care Agency (OCHCA). The controversy was that the City in Orange County where the work was conducted wanted to create a complicated chain of regulators: the Department of Toxic Substances Control (DTSC), the Santa Ana Regional Water Quality Control Board (SARWQCB), and the OCHCA. Working through Luis Lodriguezas Voluntary Oversight Program, TRG was able to secure a No further action letter from OCHCA without DTSC or SARWQCB involvement once concentrations in the ground were shown not to pose an elevated health risk.

PCE Sub-Slab Depressurization (7715)

Client:	ARIZONA CIRCLE PARTNERS
Proj Mgr:	Daniel Nunez	Completed:	In Progress
Industry:	Metal Finishers Real Estate Managers/owners	Service:	Vapor Intrusion Mitigation
This project in Los Angeles involves a building that formerly housed a metal plating shop. The processes involved with the plating operations used PCE (a chlorinated solvent that readily volatilizes) and released it into the soil beneath the site. Soil vapor surveys and assessments have identified the threat to the health of the occupants of the building due to the intrusion of PCE vapors into the building. Following a site inspection, the Reynolds Group performed a pilot study to determine the applicability of sub-slab vapor intrusion mitigation to protect the occupants from exposure to PCE. Because the release and subsequent human health threat occurred after the building was constructed, the options for mitigating vapor intrusion were limited. The buildings slab-on-grade construction further limited the options. Through the pilot study, TRG demonstrated that applying a vacuum (depressurization) to the interface between the bottom of the concrete slab and the soil immediately beneath it, PCE vapors could be captured and prevented from entering the building. TRG then designed a simple and practical depressurization system to be installed to protect the workers at the facility from the human health risk.
