Martell Division: Development, Amador County, CA (ongoing)

This private sector company owns approximately 1 million acres of property in California primarily for timberland management/production, owns and operates electrical cogeneration facilities, and develops commercial and residential property.

Initial work on this project by Stratus personnel involved conducting a Phase I environmental site assessment on an approximate 78-acre portion of land located within a former industrial area in Martell, California. Approximately 110 acres of the site is currently being developed for commercial purposes. The remainder of the site at present undeveloped. Lumber and wood product manufacturing has been conducted at the former industrial area since about 1941. The industrial area was developed with sawmills, planning mills, a box factory, a molding shop, log ponds, log decks, vehicle and equipment maintenance shops and areas, plywood and particleboard factories, dry kilns, sheds and yards, a co-generation facility, a wood-waste landfill, railroad tracks and maintenance shops, lumber preservative dip tanks, tee pee burners, and aboveground and underground petroleum product storage tanks and dispensers. These operations and facilities resulted in wide-ranging impact to soil and groundwater from diesel, gasoline, hydraulic oil, and motor oil. Other constituents requiring remediation included metals, semi-volatile organic compounds, dioxins, and polynuclear aromatic hydrocarbons. The Phase I environmental site assessment consisted of a site reconnaissance; pertinent interviews; a data base search; review of aerial photos, site and topographic maps; and the preparation of a site assessment report.

Following the completion of the Phase I ESA, Stratus personnel conducted several Phase II site investigations at the above-referenced site. Fieldwork consisted of the collection and analysis of sediment, soil and water samples for various analytical constituents. Investigative methods were conducted using equipment ranging from hand tools to heavy construction equipment. Stratus personnel were responsible for coordinating fieldwork, proper documentation, the collection of samples, the oversight of subcontractors, and preparing a report of findings. Contaminants became buried at various elevations during different periods of site changes, layouts and structures. The compressed entitlement and construction schedules of the planned commercial development added further complexity to the project.

In addition to our Phase I and Phase II work, Stratus personnel prepared county and state agency approved remedial action plans establishing clean-up goals and remediation actions for petroleum affected soils. Staff interfaced with county inspectors during identification of impacted materials and negotiations for remediation actions. Stratus personnel’s creative remedial solution of placing petroleum affected soil under finished surface paving helped save the client $300,000 in unnecessary remediation fees and reduced construction costs. Additionally, Stratus personnel coordinated off-site disposal of other designated waste with landfills, excavation contractors and haulers and provided oversight of monitoring well destruction and subsequent replacement following the completion of site improvements. The site has been redeveloped to include Safeway Lowe’s, Staples, Feed Barn, Jamba Juice and several other establishments.
