The Site was constructed as a military barracks-type facility in 1943, and was converted into a construction-trucking business center in1956. The trucking business operated until early 2017. A land redevelopment project began at the Site in June 2017. The project included building a three-floor industrial warehouse. 

In 2015, Ecology completed a Site Hazard Assessment (SHA) on the Site. The result was a ranking of “4” on a scale of 1 to 5, where “1” represents the highest risk and “5” represents the lowest risk. The SHA ranking estimates the potential threat to human health and the environment relative to other sites in Washington State.

The Site was cleaned up under the Voluntary Cleanup Program (VCP). Under the VCP, participants can clean up contamination to meet the state cleanup standards under the Model Toxics Control Act, Washington’s hazardous waste cleanup law. Ecology provides technical and regulatory review assistance through the VCP. 

In 1988-2022, cleanup was conducted at the Site. Concentrations of chemicals of concern in soil and groundwater no longer pose a threat to human
 
Ecology has determined that the cleanup action at the Site meets the state cleanup regulations (Model Toxics Control Act). Therefore, Ecology proposes to remove the Site from the Hazardous Sites List.

Site Background

A picture of the Site
A picture of the Site

The Site is located within King County’s Industrial Zone with an area of 13.58 acres. The Property was constructed as a military barracks-type facility in 1943, and was transferred to a construction-trucking business center in 1956.  The trucking business was operated until early 2017.  A land redevelopment project began in June 2017, that included building a three-floor industrial warehouse and the associated construction.

Multiple Site investigations discovered and confirmed that petroleum contaminants in soil and groundwater originated from releases of twelve leaking underground storage tanks (LUSTs) and operations of the former construction-trucking business.  In addition, vinyl chloride (VC) in the groundwater at the Site was determined as the result of migration from the adjacent Model Toxics Control Act (MTCA) cleanup site, West of 4th, to the north.     

Model Toxics Control Act

Model Toxics Control Act Cleanup Process

The Model Toxics Control Act (MTCA) is Washington’s environmental cleanup law. It provides requirements for contaminated site cleanup and sets standards that protect human health and the environment. Ecology enacts the MTCA and oversees cleanups.

​The MTCA site cleanup process is completed in steps over a variable timeline.

Site Cleanup Process

Since 1988, numerous cleanup actions were conducted at the Site, which included:

• Removal of contamination sources. Between 1988 and 2017, 12 gasoline, diesel, lube oil, waste oil, and heating oil USTs were decommissioned, and approximately 6,480 tons of the contaminated soil were removed and disposed of off-Site.

• Extraction of contaminated groundwater.  Approximately 320,000 gallons of the impacted groundwater were extracted, treated, and disposed during the soil removals.

• Performance of enhanced natural attenuation remediation.  Oxygen release compound was placed at the bottoms of the excavations as a soil amendment to promote the biological degradation of the residual COCs in groundwater.

• Implementation of the confirmational monitoring for groundwater quality.  Following completion of the contamination source elimination, groundwater samples were collected from eight monitoring wells to analyze the COCs between 2018 and 2022.  

• The analytical data demonstrated that all the COCs, except for VC, in the samples were at concentrations below either the applicable cleanup levels or the laboratory detection limits for four consecutive quarterly monitoring events. 

• Study of the VC plume occurrence at this Site.  A Site study was performed to determine the source of VC in the groundwater at this Site.  The study concluded that presence of VC in the groundwater at the northern portion of the Property originated from the neighboring MTCA cleanup Site, West of 4th.

     Loại Bỏ Consolidated Freightways Seattle Khỏi Danh Sách Địa Điểm Độc Hại

    Địa Điểm Consolidated Freightways Seattle (Địa Điểm) tọa lạc tại 6050 East Marginal Way South, Seattle, WA. Địa Điểm được xây dựng như doanh trại quân đội vào năm 1943, và được chuyển đổi thành một trung tâm kinh doanh xe tải xây dựng vào năm 1956. Kinh doanh xe tải xây dựng hoạt động cho đến đầu năm 2017. Vào tháng 6 năm 2017, một dự án tái phát triển đất đã bắt đầu tại Địa Điểm. Dự án này bao gồm xây một nhà kho công nghiệp ba tầng.

    Vào năm 2015, Bộ Môi Sinh (Ecology) đã hoàn thành Đánh Giá Nguy Cơ Địa Điểm (SHA). Kết quả là xếp hạng “4” trên thang điểm từ 1 đến 5, trong đó “1” thể hiện nguy cao nhất và “5” thể hiện nguy cơ thấp nhất. Bảng xếp hạng SHA ước tính mối đe dọa tiềm tàng đối với sức khỏe con người và môi trường so với các địa điểm khác ở Bang Washington.

    Địa Điểm đã được tẩy nhiễm theo Chương Trình Tẩy Nhiễm Tự Nguyện (VCP). Theo VCP, những người tham gia có thể làm sạch ô nhiễm để đáp ứng các tiêu chuẩn tẩy nhiễm của tiểu bang theo Đạo Luật Mô Hình Kiểm Soát Chất Độc. Đây là luật tẩy nhiễm chất độc của bang Washington. Ecology hỗ trợ về mặt kỹ thuật và xem xét các quy định thông qua VCP.

    Từ năm 1988 đến 2022, việc tẫy nhiễm đã được tiến hành tại Địa Điểm này. Nồng độ các chất hóa học được quan tâm trong đất và nước ngầm không còn là mối đe dọa đối với sức khỏe con người và môi trường. Ecology đã xác định rằng công tác tẩy nhiễm tại Địa Điểm đáp ứng các quy định về tẩy nhiễm của tiểu bang (Đạo Luật Mô Hình Kiểm soát Chất Độc). Do đó, Ecology đề xuất loại bỏ Địa Điểm này khỏi Danh Sách Địa Điểm Độc Hại.

    從危險站點名單中移除Consolidated Freightways Seattle站點

    Consolidated Freightways Seattle (站點) 位於華盛頓州西雅圖6050 East Marginal Way South。該站點於 1943 年建為軍營式設施,1956 年改建為建築卡車業務中心並一直運營到 2017 年初。 2017 年 6 月,土地再開發項目開始。該項目包括建造一個三層樓的工業倉庫。

    2015 年,Ecology 完成了站點的現場危險評估 (SHA)。結果是從 1 到 5 的等級中的“4”級,其中“1”代表最高風險,“5”代表最低風險。 SHA 排名評估了相對於華盛頓州其它站點對人體健康和環境的潛在威脅。

    根據自願清理項目(VCP)該站點已清理乾淨。在VCP項目裡,根據華盛頓州危險廢物清理法《示範毒物控制法》,參與者要清理污染,達到州清理標準。通過 VCP,Ecology提供技術和監管審查幫助。
    1988-2022 年間,站點清理工作開展。土壤和地下水中關注的化學物質濃度不再對人類健康和環境構成威脅。Ecology已確定站點的清理行動需符合州清理法規《示範毒物控制法》。因此,Ecology提議將該站點從危險站點名單中移除。
