In addition, since many of the references are 3rd or 4th generation copies, some pages may not be legible, but are the best available. Government or by the U. In general, these reports summarize types of environmental damages and associated mining waste management practices at sites on or Dell Precision 530 NEC NR-7800A for the NPL as of February 11, 56 FederaLRe2ister Commencement Bay is a large deep-water embayment approximately 9 miles square in southern Puget Sound see Figure 1. The Superfund Site encompasses the Port of Tacoma and includes 10 to 12 miles of shallow water, shoreline, and adjacent land, most of which is highly developed and industrialized. The marine boundary of the site is limited to the shoreline and water at depths of less than 60 feet below mean low tide.

These Operable Units are: Operable Units 1, 3, and 5 are not discussed in this summary because they involve point and nonpoint source pollution. In some cases, this slag has been identified as a significant source of heavy metals in Commencement Bay; and thus, it is relevant to Operable Units I and 5 as well Reference 12, pages Al and A9.

There are three docks and four outfalls along the shoreline, including one immediately north of the ASARCO property, which is owned by the City of Tacoma and used for storm-water runoff. The property also includes a depression that was used as a cooling pond.

EPA determined that structural demolition, temporary storage, and offsite and onsite surface-water and storm-water controls were necessary first steps toward site stabilization. Approximately people are located within. The response action began in Dell Precision 530 NEC NR-7800A Ten of the 11 sites were completed in Originally, sediment contamination along the Ruston-Point Defiance shoreline was part of Operable Unit 1. In Operable Unit 6, off-shore sediments along the Ruston- Point Defiance shoreline, the potential contaminants of concern include arsenic, antimony, cadmium, chromium, copper, lead, nickel, zinc, PAHs, and DMA.

The contaminants of concern in Operable Unit 7, ASARCO smelter demolition, include arsenic, antimony, cadmium, chromium, copper, lead, nickel, and zinc.

Dell Precision 530 NEC NR-7800A 67 acres are occupied by the smelter facility and the remainder includes the parking lot and undeveloped land Reference 2, page The Tacoma plant began operations as a lead smelter in under the ownership of the Tacoma Smelter Company. In the period from toDell Precision 530 NEC NR-7800A facility converted to a copper smelter specializing in refming copper ores having high concentrations of arsenic and other impurities. Refining operations ceased inbut smelter operations continued until March ; during this period, copper produced from the smelting operations was shipped to Texas for refining.

The arsenic processing plant operated until January or February Reference 1, page 1; Reference 3, page I-i. Smelter production averaged approximately 70, tons of anode copper per year Reference 2, page Many of the by-products were further refined to produce marketable products.

For example, dust from the smelting process was roasted to Dell Precision 530 NEC NR-7800A arsenic trioxide and metallic arsenic. Beginning insulfur dioxide from the converter operation was used to produce sulfuric acid and liquid sulfur dioxide Reference 5, page 2. In addition, some of the slag was sold as rip-rap, ornamental rock, and road ballast Reference 3, page When the facility was operating, ASARCO used baghouses, electrostatic precipitators, and cyclones to control air emissions. The extent to which the controls were used, their effectiveness, and the timeframe in which they operated is unknown.

Federal and State emission standards continued to be a troublesome issue until the Smelter closed in Reference 5, page 3. Since many buildings on the ASARCO property were built on contaminated soils, EPA felt the removal of contaminated structures was necessary to examine and characterize the extent of contamination. Site stabilization and demolition of the most contaminated buildings around the Dell Precision 530 NEC NR-7800A stack was completed in Table 1 shows the contaminants of concern and potential exposure pathways for the Operable Units 2, 4, 6, and 7.

The uppermost geological unit in the area is glacial till. The elevation ranges from to feet above mean sea level with a fairly uniform decrease in elevation towards Commencement Bay.

Construction has removed most of the dense vegetation from the study area. Federal and State emission standards and variances continued to be contentious issues until the Smelter closed in Reference 5, page 3.

The exact emissions rates are unavailable, but arsenic to lead emissions were estimated at about 6 to 1, arsenic to mercury emissions were about to 1, and mercury and chromium were approximately equal Reference 6, page 1. Long-term ambient air-monitoring records at sampling stations near the Tacoma Smelter allowed comparisons between pre- and post-shutdown ambient air concentrations for arsenic. In general, the post-shutdown data showed significant declines in ambient concentrations compared to periods when the Smelter was in operation Reference 4, page Post-shutdown ambient concentrations of arsenic were comparable to those recorded when Dell Precision 530 NEC NR-7800A Smelter was not in operation during labor strikes in and Reference 4, page ; Reference 6, page When ambient air samples collected during the ASARCO strike of were compared to ambient air samples collected after the strike, ambient air loadings increased by the following factors averaged across the monitoring stations: Samples, collected four times a year from households in and by researchers from the University of Washington, indicated that outdoor arsenic concentrations in North Tacoma exceeded both indoor arsenic concentrations and the mean National ambient range of 5 to 10 nanograms per cubic meter Reference 4, page Firmware update for NEC NRA HH 16x CD-RW drive; Dell P/N: 2M, 8K NEC 16X NRA CD-R/RW Drive, vDA, A03 Precision Precision Precision NEC 16X NRA CD-R/RW Drive, vDA, A Driver Type: Firmware.
