Tacoma Smelter Plume: Model Remedies Guidance gets an update

To encourage cleanup of soil contaminated by the former Asarco smelter in Tacoma, we've updated our Tacoma Smelter Plume Model Remedies Guidance. For almost 100 years, the Asarco Company operated a copper smelter in Tacoma. Air pollution from the smelter settled on the surface soil of more than 1,000 square miles of the Puget Sound basin. Arsenic, lead, and other heavy metals are still in the soil as a result of this pollution.

This guidance was created to encourage cleanup of Asarco contaminated soil during property development. It provides straightforward directions on soil sampling and cleanup of soil contaminated with arsenic and lead within the Tacoma Smelter Plume. In July, we launched a revised version of the guidance, replacing the older, 2012 version.

The guidance was written primarily for developers who build residential housing or commercial buildings. However, anyone who wants to sample and clean up their Asarco contaminated soil within the Tacoma Smelter Plume can use this guidance. The guidance streamlines the sampling and cleanup process and eliminates the need to develop separate sampling and cleanup plans. When developers use the remedies covered in this guidance to clean up their properties before building structures, Ecology is able to issue timely opinion letters stating that the cleanup meets state requirements.

In updating the guidance, we kept the same format, updated some information and links to resources, and added a new chapter. Some of the revisions answered and clarified frequently asked questions, such as calculating the minimum number of soil and duff samples needed. The new chapter describes sampling and remediation in natural areas, such as steep slopes, wetlands and their buffers.

Please, note that the publication number has changed from 12-09-086-A to 19-09-101.

If you have questions about the revised Tacoma Smelter Plume Model Remedies Guidance, contact our Technical Assistant, Eva Barber at 360-407-7094 or Eva.Barber@ecy.wa.gov.

Tacoma Smelter Plume Yard Program

Work on Vashon-Maury Island moves ahead

If you live in the North end of Tacoma or the southern tip of Vashon-Maury Island, you have likely heard about the Tacoma Smelter Plume. However, if you just moved here, the following information may be new.


The former ASARCO smelter stack.



For nearly 100 years a smelter operated in the small town of Ruston. Air emissions from the smelter were carried by the wind to areas in King, Pierce and Thurston County. These air emissions contained heavy metals including arsenic and lead, which settled on surface soils. The highest levels of soil contamination are seen closest to the former smelter and decrease with distance.

 

Soil replacement work

Through our Residential Yard Sampling and Cleanup Program, we are working on 14 yards and a community-park in the southern end of Vashon-Maury Island. Work started on the first yard in early March 2019.

If you live in this neighborhood, you will likely see construction-related traffic. You may notice orange fencing, closed sidewalks, and Ecology’s Yard Program banner. The contractor usually works on a few yards at a time, which means workers may travel between yards with equipment. Construction can be noisy, and it is important to pay attention to trucks and large machinery that are coming and going. This construction will likely go through July 2019.    

Please call us if you see:

• Dust in the air from construction.
• Soil on the sidewalk or street.
• Mud or water running off the property.
• Dump trucks without covers.

 

Soil sampling

If you live on the southern end of Vashon-Maury Island it is likely that your property has already been sampled. To find out if your property has soil sampling results, go to our public database and enter your address. Soil sampling is for existing, residential properties. If you are a new homeowner, and your soil hasn’t been sampled, you can fill out an access agreement and get your yard sampled, too. Soil sampling is free and completely voluntary.

Future soil replacement

Currently, 53 properties qualify for soil replacement on Vashon-Maury Island. By the end of 2019, we will have removed and replaced soil on 35 of these properties. Unfortunately, we are not able to remove and replace soil on all the properties that qualify. Some properties have steep slopes or are located in areas we don’t work, like forests or vacant lots. And, sometimes, we are unable to coordinate with the property owner. At the end of the program, we will offer one last opportunity for residents with qualifying properties to participate in our Yard Program.
 


By the end of 2019, we will have removed and

replaced soil on 35 properties on Vashon-Maury

Island.

Soil left behind

The main objective of the Tacoma Smelter Plume project is to reduce human health risks from arsenic and lead in soils. Soil replacement is focused on the high-use areas around homes and in areas where children play. Soil contamination may remain in undeveloped and forested areas. It is important to practice healthy actions like taking shoes off at the door and washing hands after working or playing in the dirt no matter where you live within the Tacoma Smelter Plume.

New Online Map: Dirt Alert

The new map is mobile friendly, making it easy to access.

from your home computer or your phone.  

This month we launched a new online Dirt Alert map. The map focuses on the Tacoma Smelter Plume, but also covers areas in the state where soil contamination may exist from arsenic-related contamination: 

·        Everett Smelter cleanup

·        Upper Columbia River Lake Roosevelt cleanup site 

·        Five Washington counties where soil contamination may exist in former orchard lands

By putting both information and data in one place, we hope to make it easier for residents to find out about arsenic-related soil contamination and resources. The new web application replaces two older, online maps, the Arsenic in Soil Database and the Everett and Tacoma Smelter Search. 

New look- Same data

The upgrade means faster downloading times and the ability to access the map by phone. The map also visually displays soil sampling data. Within the Tacoma Smelter Plume and Everett Smelter cleanup area, the map provides access to:

·        Soil sampling maps

·        Soil replacement paperwork

For yards outside of the Everett Smelter cleanup area or Tacoma Smelter Plume Yard Program service area, the map links to our Healthy Actions webpage that teaches you how to protect yourself from arsenic and lead in dirt, and provides contacts for more information.

Tacoma Smelter Plume Yard Program progress

Steady movement forward

We are breaking ground, removing dirt, and moving forward on cleanup of 39 yards in north Tacoma, and 16 yards on Vashon-Maury Island.  This work is part of Department of Ecology’s (Ecology) larger efforts to address soil contamination left behind by the former Asarco smelter.

For nearly 100 years, the former Asarco Company operated a copper smelter in north Tacoma.  Air pollution from the smelter settled on surface soils over more than 1,000 square miles of the Puget Sound.  Arsenic, lead, and other heavy metals are still in the soil as a result of this pollution.

We have been working on soil replacement in Tacoma
since 2013.  Our work has been focused in Area 1 and 2
 of the Study Area.  The Study Area is colored green.

Ecology’s Yard Program is offering soil replacement to the most highly contaminated yards.  To date, we have found 1,186 yards that qualify for the program.  We have completed soil replacement on 224 of those yards in the Tacoma area (see map), and 245 yards in our Yard Program Service Area.  Our Yard Program Service Area includes parts of North Tacoma, Ruston and the southern end of Vashon-Maury Island.

Work underway

Our funding was put on hold when a capital budget was not passed during the 2017 legislative session.  As a result, last year we scaled back, and worked on a small group of 17 yards in Tacoma.  In early 2018, the capital budget passed, freeing up funding to continue work.

This year we are working on 39 yards in the Tacoma area.  We break the work into groups of yards.  The largest group is 25 yards located in Area 2 of the study area (see map).  The remaining 14 yards are located outside of the study area. To date, yards that we worked on outside of the study area in Tacoma have levels of arsenic over the EPA action level and are funded by the EPA.

If you live in Area 2, you will likely see construction-related traffic.  You may notice orange fencing, closed sidewalks, and Ecology’s Yard Program banner.  The contractor usually works on a few yards at a time, which means they may travel between yards with equipment.  Construction can be noisy, and it is important to pay attention to trucks and large machinery that are coming and going.  Construction in this area will likely start in mid-July.  We hope to start work on Vashon-Maury Island in the fall of 2018.

Tacoma Smelter Plume: New Outreach in Spanish

*Blog en Español*

Ecology launched new Spanish language outreach in Federal Way, last month. In partnership with Public Health Seattle King County and the Latino Community Fund we developed a Facebook advertisement post for the Dirt Alert Program pictured at right.

Based on community feedback, we focused on taking off your shoes. This is an easy way to reduce the risk from arsenic and lead that may be in the dirt that is tracked into your home. The former ASARCO smelter left arsenic and lead in the soil in King, Pierce, and North Thurston counties (see map of affected area here, in English).

The Dirt Alert program has a website with a list of more Healthy Actions (in Spanish and English).  

 We Recommend:

We also created a new page on www.DirtAlert.info (the Dirt Alert Partner website) in Spanish that gives people some basic information and links to more resources about the Dirt Alert program.  

This is not our first Dirt Alert outreach in Spanish. In 2014, Ecology translated several webpages about the Tacoma Smelter Plume into Spanish (see picture below) to reach the Spanish speaking community in the Plume.

Tacoma Smelter Plume: 2016 Yard Program Construction Update

September marks the fast approaching arrival of fall, and a halfway point for this season’s Yard Program work in the Tacoma Smelter Plume.  This year we will be working through the winter, but the sunny, fall days in September have given us lots to be cheerful about. The good weather has helped keep our contractors on pace replacing soil in residential yards.

As we near the end of September, we are wrapping up soil replacement on Group 3 (21 yards) and beginning construction on Group 5 (10 yards) (see map). We removed soil on half of the residential yards in Group 4 (50 yards) and are on track to finish construction on these properties by February 2017.

Prioritizing work on yards with the highest risk

This year, we are mostly working on yards within the Study Area (see map). However, ten (Group 5 on map) of the 81 yards scheduled for this year are located outside of the Study Area.  These properties have the highest levels of soil contamination that we have found within the plume (arsenic over 230 parts per million).

The yards that qualify for soil replacement may appear to be randomly scattered throughout the Yard Program service area. However, we are prioritizing these yards because the levels of arsenic or lead pose a higher risk than other yards. The soil replacement work on these ten yards is partially funded by the Environmental Protection Agency (EPA).

Working with hundreds of property owners each year…

We are working with nearly 300 property owners at any one time.  Each year, we continue to communicate with the previous year’s participants, work with residents currently receiving soil replacement, and plan with residents for next year’s construction. All this planning allows us to remove and replace soil on 80-100 properties annually. For more information on our soil replacement sequence you can go to our Yard Program Updates page.

The Yard Program cleans up arsenic and lead from the former Asarco smelter in Tacoma.  It is a voluntary program that’s offered at no cost to the homeowner.  This work is part of Ecology’s efforts to sample and replace contaminated soil in the Tacoma Smelter Plume.  The plume is a 1,000 square-mile-area of arsenic and lead contamination from the former Asarco smelter in north Tacoma.

Tacoma Smelter Plume: 2016 Yard Program Construction Underway

The Tacoma Smelter Plume Residential Yard Sampling and Cleanup Program work is well underway for 2016.

We started construction on the first yards in early June. Currently our contractors are actively working on 16 yards. The contractors generally work on several properties at a time, removing and replacing the soil in groups to pool resources and localize the construction activity.

Properties receiving soil replacement in 2016.

In 2016, Ecology will remove contaminated soil on a total of 80 residential yards in Tacoma (see map at right). Work hours run from 8 a.m. to 5 p.m. Monday through Friday and some Saturdays with permission from Ecology. With so many properties, you will likely see construction related activity in those neighborhoods through February 2017.

The Yard Program cleans up arsenic and lead from the former Asarco smelter in Tacoma. It is a voluntary program that’s offered at no cost to the homeowner. This work is part of Ecology’s efforts to sample and replace contaminated soil in the Tacoma Smelter Plume. The plume is a 1,000 square-mile-area of arsenic and lead contamination from the former Asarco smelter in north Tacoma.

Tacoma Smelter Plume: Recap of Tacoma Public Meetings

By Jill Reitz, Environmental Planner, Toxics Cleanup Program



This map shows the estimated highest arsenic levels

in the plume. A property is likely to have higher or

lower levels than what is shown on the map. The only way to know for sure is to sample the soil.

Last week, Ecology held two public meetings on the progress of the Tacoma Smelter Plume project.  We had a turnout of over 50 people who came out to learn about yard sampling and cleanup in Tacoma neighborhoods. Please see our slideshow presentation to learn more about the topics we covered. Here are a few of the common questions and answers that were discussed:

How do I sign up for soil sampling?

If you live in the most impacted areas of the plume (see map right), you likely qualify for one of our free soil sampling programs.  Please visit our sampling webpage to learn more and sign up.

Why do I have to wait for soil replacement?

There are around 1,100 properties slated for soil replacement.  We are planning to replace soil on an estimated 100 properties a year.  We are first working in areas with the highest percentage of properties that qualify for soil replacement.


At the meetings, we presented maps showing our schedule for soil replacement in the service area.  Please see the Study Area sequence map and the Tacoma sequence map for more information.



What are the health impacts of arsenic and lead?

Long-term exposure to small amounts of arsenic or lead on a regular basis can increase your risk for certain health problems.  Arsenic can cause cancer, heart disease and diabetes.  Lead can lead to developmental delays or behavioral problems.  Please visit our webpage on the health effects for more information.
 

What do I do if I have elevated arsenic but do not qualify for soil removal?

We recommend healthy actions to reduce your exposure to contaminated soil. This includes things like: 

Health Actions are simple things you can do to protect

yourself and your family.

• Wash your hands before eating
• Take your shoes off at the door
• Vacuum at least once a week
• Peel produce grown in your garden

Please visit the Healthy Actions webpage for more information.
