Relevant Experiance

Project Director – Site Characterization / Remedial Investigation / Feasibility Study,
Superfund Site, Arvin, CA:

Dr. Estiri conducted a remedial investigation and feasibility (RI/FS) study under EPA, Region IX for a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) site in Arvin, California.
The site is a former pesticide reformulation facility that ceased operation in the mid-1980s. Contamination at the site consisted of pesticide and herbicide residuals in a complex soil and groundwater matrix. In addition to the completion of the RI/FS reports, work involved installing monitoring wells, soil borings, quarterly groundwater monitoring, data analysis, and chemical fate and transport modeling. Characterization of liquid and sludge wastes in on-site aboveground storage tanks (ASTs), and maintenance of the RCRA cap covering a portion of the site were also performed.

Project Director – Site Y at Camp Haan,
Riverside County, CA:

Camp Haan is a former prisoner of war/troop assembly area located next to March Air Reserve Base, and is part of the USACE Formerly Used Defense Sites (FUDS) Program. Site “Y”, at former Camp Haan, consists of a former landfill that contained an incinerator associated with waste and ash.
As the major subcontractor to Panacea, Inc., Eco conducted a preliminary assessment/site inspection for the 76-acre site. The total contract value for Eco was $1.2M. In March 2007, Eco, under Dr. Estiri’s direction, was selected by USACE to continue working at Camp Haan by conducting quarterly groundwater sampling. So far, Dr. Estiri has provided oversight to 22 groundwater samplings.

Project Director – Real Estate Development Authority (RDA), Phase I ESA and Phase II Site Investigation,
City of Carson, CA:

Dr. Estiri performed as project director for an undeveloped property located in the City of Carson, CA that had been identified as a hazardous waste site during a Phase I ESA conducted in 1990. Eco’s excavation activities revealed that the contaminated soil was far in excess of the 5 feet depths estimated by the previous contractor. With the concurrence of the client, Eco collected seven soil samples, which were analyzed for TPH and VOCs, and then excavated six exploratory trenches adjacent to and within the site to delineate the horizontal and vertical extent of impacted soil. Visibly contaminated soil was encountered within four trenches at depths of 17 feet bgs. Based on the results of soil sampling from 11 boring locations analyzed for TPHs and BTEX using photo-ionization, Eco is preparing a conceptual model and high-level-of-confidence Remedial Action Plan for this site.

Project Director – Phase I Environmental Site Assessment (ESA) for Orange County Transportation Authority (OCTA),
Orange County, CA:

Dr. Estiri directed production of a Phase I Environmental Site Assessment (ESA) for each of 14 properties located in Orange County, California within the OCTA Environmental Mitigation Program. Each Phase I environmental site assessment (ESA) was conducted on behalf of Paragon Partners, Ltd. The purpose of the investigation is to gather sufficient information to develop an independent professional opinion about the environmental condition of the parcels as well as identify actual or potential environmental contamination impacting the sites.

Project Director – Los Alamitos Joint Forces Training Base (FJTB), Los Alamitos, CA:

The JFTB is located in the city of Los Alamitos, California in northwestern Orange County in the Los Angeles basin of southern California. USACE retained Eco to remove and dispose of two underground storage tanks (UST) within the JFTB.
Dr. Estiri directed the locating and removal of USTs from the site, as well as the removal of impacted soils surrounding the tanks. Tasks included removal and capping of electrical lines and piping, UST cleaning and removal, confirmation soil sampling and analysis, suppression of odor/vapor emissions, decontamination procedures, and management of investigation-derived wastes.

Project Director – Asbestos, Lead, Mercury, and PCBs, Buildings Survey for March Air Reserve Base (MARB),
Riverside County, CA:

Eco was retained by USACE, Los Angeles District, to conduct an asbestos, lead, mercury, and polychlorinated biphenyls (PCBs) survey at four buildings within the March Air Reserve Base (MARB) in Riverside County, California. This project, under Dr. Estiri’s direction, was to assess the likelihood that asbestos was present in concentrations greater than 1 percent in suspect, accessible construction materials in the buildings and whether lead was present on the painted surfaces of the site buildings at concentrations greater than or equal to 1.0 mg/cm2 using a portable, XRF analyzer. In addition, inventory of MCM and PCB materials at the sites was provided. A minimal intrusive sampling technique to sample suspect construction materials was used for one occupied building. An abatement priority system was developed to delineate the condition of various materials reported to contain asbestos. Results provided the likelihood of contaminated materials and the appropriate (according to regulatory standards) precaution/procedures as well as the possible need for further investigation.

Project Manager – Phase I Temple Avenue 4th Rail ACE Project,
Pomona, CA:

Dr. Estiri was the Project Manager for Eco & Associates who was subcontracted by Paragon Partners, Ltd. to perform Phase I environmental studies at planned construction areas within the Union Pacific Railroad corridor included in the Alameda Corridor East (ACE) construction project. The ACE project consists of railroad improvements along approximately 2.5 miles of railroad corridor in the City of Pomona, California. The site consists of 37 right-of-way takings planned for temporary or permanent easements.
Based on the findings of the Phase I Environmental Site Assessment performed by Eco, a soil investigation was recommended for all areas of planned construction that required excavation of soil beneath the site. Due to the intrusive soil investigation, elevated lead concentrations were deemed to be present in shallow soil at the site. Special handling and placement for lead impacted soil was recommended by Eco. Recommendations for the handling of impacted soil were based on Caltrans variances since the site follows Caltrans construction-related guidelines. Eco also provided recommendations for any excess lead-impacted soil generated during future site construction activities.

Project Manager – Environmental Site Assessment & Aerially Deposited Lead Investigation Workplan,
City of Monterey Park, CA:

Dr. Estiri was the Project Manager for the City of Monterey Park Redevelopment Agency Phase I ESA for the Paramount Boulevard On/Off Ramps of State Highway 60 (SR60) in Montebello, Los Angeles County, California. The project was to improve the interchange by expansion of the existing on/off-ramps to the Pomona Freeway. The Phase I ESA was conducted in general accordance with the scope and limitations of American Society for Testing and Materials (ASTM) E1527-05 standards.
No environmental concerns or associated with the property were identified. However, based on experience with similar projects, Eco recommended investigations for aerially deposited lead (ADL) and weed control chemicals for the unimproved areas adjacent to the roadways where excavations were planned during project improvements. Subsequently, Eco was retained to prepare a Workplan for a Phase II ESA on the site and an investigation into ADL. Eco prepared a Workplan and Health & Safety Plan for the scope of work in December 2007. The lead testing was to be done in accordance with the California Department of Transportations’ (Caltrans) guidelines. Over 100 samples were proposed from both sides of the highway.
