A Phase I Environmental Site Assessment (ESA) was performed for the Samoa - Redwood Marine Terminal 1 and was separated into four individual reports based on parcel ownership. The Humboldt Bay Harbor, Recreation, and Conservation District portion comprises six parcels and an approximately 185-acre portion of a 300-acre former lumber mill located on the Samoa Peninsula in Samoa, Humboldt County, California (Site). In 1889, the Samoa Land and Improvement Company purchased 270 acres of land on the peninsula opposite of Eureka, California. In 1892, the John Vance Mill and Lumber Company purchased land on the Samoa Peninsula for the construction of a new sawmill after their Eureka, California, mill burned in a fire. In 1893, the Eureka and Klamath River Railroad connected the Samoa Peninsula and Arcata, California, providing a more efficient means of logging imports to the sawmill operations. In 1900, the Hammond Lumber Company acquired the sawmill, adding a sash and door factory in 1909. In 1912, the sawmill was recognized as the "Hammond Lumber Company". Between 1917 and 1919, the Hammond Lumber Company built an emergency shipyard to help with the United States efforts in World War I and seven wooden steam ships were built at the Samoa facility. In 1956, Georgia Pacific acquired the mill, adding a plywood mill in 1958. In 1963, Georgia Pacific developed the bleached kraft pulp mill to the west of the Site and replaced the old sawmill with a modern sawmill in 1964. In 1972, the Louisiana Pacific Corporation acquired the former lumber mill and continued operations until the last old growth timber was milled in 1980. In 1994, the pulp mill to the west of the Site was converted to a chlorine-free pulp mill. The Simpson Timber Company acquired the former lumber mill in 1998 and listed the former lumber mill for sale in 2001. At the time of the Phase I ESA, the Site is currently owned by the Humboldt Bay Harbor, Recreation, and Conservation District and is occupied by a commercial fishing facility operated by the Hag Fish Corporation; a recreational boat repair facility; and a firewood facility operated by Lee Fegis Firewood. The northern portion of the Site is used for dredge spoils from Humboldt Bay Harbor dredging activities. Recommendations from the Phase I ESA are listed below.
Recognized Environmental Conditions (RECs):
*Further characterize the lead and dioxin/furan contamination in soil and metals and total petroleum hydrocarbons as diesel (TPH-d) in groundwater beyond the perimeter of the Samoa Roundhouse Site.
*Further characterize the gasoline, metals, and solvents contamination in soil, soil gas, and groundwater beyond the perimeter of the Evergreen Pulp Mill Site.
*Characterize the dioxin/furan and polycyclic aromatic hydrocarbon (PAH) contamination in soil around the former refuse burners on the Site.
*Collect subsurface soil and groundwater samples within the former sawmill, planing mill cogeneration power plant, powerhouse, fuel house, boiler house, and pipe house building foundation boundary for metals, total petroleum hydrocarbons (TPH), volatile organic compounds (VOCs), methyl tert-butyl ether (MTBE), and benzene, toluene, ethylbenzene, and xylenes (BTEX) analysis.
*Collect grab surface soil samples adjacent to the 200-gallon diesel aboveground storage tank (AST) for TPH-d analysis.
*Collect surface soil samples within former building foundation and drip line boundaries for lead and asbestos analysis.
*Collect dredge spoil pile samples for hazardous waste analysis including metals, TPH, and polychlorinated biphenyls (PCBs).
*Confirmation sampling on the boundary between the Site and the two former 10,000-gallon diesel ASTs to verify contamination has not migrated to the Site or seek regulatory closure by the State of California Water Resources Control Board (SWRCB) for the two former 10,000-gallon diesel ASTs located on the northeast portion of the Samoa Roundhouse Site.
*Confirmation sampling adjacent
