Tacoma Smelter Plume: Reduced Services for Residents


Picture of children playing in dirtWe are reducing some services to residents

Because a state capital budget was not approved, Ecology did not receive any new funding. We are using the money we didn’t spend fully from last biennium to fund our program. We must cut back on the services we offer to the residents of the Tacoma Smelter Plume area for this next year to fit this remaining budget.
 
Throughout the plume area, soil sampling will be limited or temporarily stopped. We will not replace soil on 42 yards and one park play area this next year as planned. This will have a domino effect - residents further down the list will have to wait longer to have their soil replaced. Also, the health departments must reduce their education and outreach work. If a capital budget is not approved in the next 6-12 months, we will need staff restructuring, potential layoffs, and a complete stop of all services in July 2018.

Specifically, we will no longer be able to:

  • Replace soil on 42 yards and one park play area which were planned for this year
  • Complete planning for soil replacement on over 100 properties
  • Sample soil for new residents in the Yard Program service area
  • Sample soil on Vashon-Maury Island
  • Fully fund Pierce and King County Health Departments to do healthy action outreach with residents and handwashing demonstrations in childcares and schools
  • Provide commercials to inform residents about the plume and healthy actions they can take
  • Fund Thurston County for outreach and education work

We will update you when we have more information

Ecology staff are working with the Pierce and King County Health Departments to provide the most cost efficient services and are still working out what we can provide. We will continue to update residents during this limited funding period on any further changes. To stay informed, you can:

The Tacoma Smelter Plume Project has dedicated funding but we depend on the capital budget

The funding for this project is from a bankruptcy settlement with the ASARCO company. However, the money sits in the Cleanup Settlement Account which is a capital budget item. Every biennium the legislature must approve Ecology’s request to spend the funds. For 2017-2019, we requested nearly $24 million to provide full services in the plume area. This year, the capital budget was not passed, and we did not receive funding. We are currently using the money leftover from last biennium, about $4 million to fund our reduced services for one year. In 2018, we will request funding for our work through the last year of the 2017-2019 biennium cycle. If we do not receive additional funds, we will stop all services in the plume area in the fall of 2018.

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.

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.
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.

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.

Tacoma Smelter Plume: Public meetings focus on next phase of sampling, soil replacement work

Contractors meet with staff to review plans for soil replacement 
on a residential yard.
By Jill Reitz, Environmental Planner, Toxics Cleanup Program 

This summer, Ecology will continue a multi-year project to replace soil on yards contaminated decades ago by pollution from an old copper smelter in Ruston. This year, we will dig up, remove and replace soil at about 80 north Tacoma yards.

The former Asarco Company smelter released air pollution for almost 100 years, which settled on the surface soil over more than 1,000 square miles in Pierce, King and Thurston Counties. Arsenic, lead and other heavy metals are still in the soil in the area now known as the Tacoma Smelter Plume.

Three upcoming meetings will focus on yard sampling and replacement, cleanup at parks and childcare facilities, technical assistance, and continuing outreach and education in the Tacoma Smelter Plume.

Tacoma Smelter Plume: 10 years of protecting kids from arsenic and lead in soil

By Jill Reitz and Stacy Galleher, Toxics Cleanup Program


This year marks the ten-year anniversary of Soil Safety Program. The effort provides free soil sampling and cleanup for play areas within the Service Area, an approximately 200-square-mile area within the Tacoma Smelter Plume. The plume is a 1,000-square-mile-area of arsenic and lead contamination from the former Asarco smelter in Ruston/north Tacoma.

Ten years at work!

Since 2006, we have sampled more than 1,000 child play areas including schools, parks, childcares, camps, and multi-family housing. We replaced soil or posted signage at 86 childcares, 25 schools, and 24 parks.

If a play area had an average for arsenic or lead above the state cleanup levels, we offered to replace soil. Some play areas were not accessible for cleanup, such as in forested areas or on steep slopes. In these areas, we instead posted signs to inform visitors.

In the past year we replaced a total of 6,130 tons of soil – the weight of about 13 Boeing 747 airplanes.


Contractors use an excavator to start scraping away soil.
In 2015, we replaced soil at two parks:

  • Baltimore Park – Ecology replaced the top 12 inches of soil in the play area (see map on blog)
  • Optimist Park – Ecology replaced the top six inches of soil in the play area (see map on blog)

We used a total of 980 pounds of grass seed and some sod to cover all that soil with grass. Fences still remain up around the new grass at Baltimore and Optimist parks until later this summer to allow the roots to establish.

New soil is delivered to the site to
back fill the excavated areas.
Also, early in 2016 we replaced soil in Fort Nisqually at Point Defiance Park – we replaced soil both inside the fort and in the nearby meadow (see map on blog.)

This work was a great opportunity to create new pathways for visitors within the Fort’s palisades. Ecology also added new mulch to the picnic area near the parking lot.

Tacoma Smelter Plume: Work begins to clean up contamination at Fort Nisqually in Point Defiance Park

By Stacy Galleher, Public Involvement Coordinator, Toxics Cleanup Program

Ecology’s Soil Safety Program has started construction work to replace contaminated soils at Fort Nisqually Living History Museum within Point Defiance Park. The former Asarco copper smelter in Tacoma, contaminated 1,000 square miles with arsenic and lead from its smokestack.

Construction schedule and closed areas

The Fort will temporarily close in January and February 2016.  We plan to remove soil from inside the Fort and nearby meadow area (see map below). Once the work is finished, fresh sod will be placed and protected so it can take root. Also, we will add mulch to the picnic area near the parking lot.  The Fort will reopen in March, and the first event of 2016 will be "Sewing to Sowing" on April 23.  Fort staff will be available during the temporary closure at (253) 591-5339 or fortnisqually@tacomaparks.com.http://www.ecy.wa.gov/programs/tcp/sites_brochure/dirt_alert/soilSafety/soilsafety.htm

Tacoma Smelter Plume: Work begins to clean up Baltimore and Optimist parks; Vassault Park re-opens

By Stacy Galleher, Public Involvement Coordinator, Toxics Cleanup Program

Ecology’s Soil Safety Program has started construction work to replace contaminated soils at the playfields at Baltimore and Optimist parks in Tacoma. The former Asarco copper smelter in Tacoma contaminated 1,000 square miles with arsenic and lead from its smokestack.

Construction schedule and closed areas
Baltimore Park maps showing closed and construction areas.


Baltimore Park:

Baltimore Park closed Aug. 24 when the construction fence was placed around it. Construction started Aug. 26.


We are replacing the top 12 inches of soil in the play area outlined in orange. We will dig a shallower depth around the trees to protect the roots (see map).





Optimist Park
Optimist Park maps showing closed and construction areas
At Optimist Park, construction will start in mid-September as soon as we place new soil at Baltimore Park. Then both parks will be seeded with grass at the same time.

We will replace the top six inches of soil in the play areas outlined in orange (see map). We will dig a shallower depth around the trees to protect the roots. We are not removing soil within the ball field because it has arsenic and lead below cleanup levels.

At both parks, construction will continue through November. Also, the playfields will remain closed until summer of 2016 to protect the new grass and allow time for it to grow.

Want more information?

Go Enjoy Vassault Park!
After the large 8-acre cleanup effort, Vassault Park re-opened to the public last week. Thanks for your patience during the longer-than-expected closure. The lawn is finally fully grown, healthy, and ready for use.

Tacoma Smelter Plume: What's under the new grass at Vassault Park in Tacoma?

By Jill Reitz, Cleanup Outreach Coordinator, Toxics Cleanup Program

Over the past few months, you may have noticed orange fences, trucks, new dirt, and new grass at Vassault Park in Tacoma. Ecology has been cleaning up soil contamination at playfields in the park as part of the ongoing work to clean up arsenic and lead. These toxic metals were carried by the wind from the former Asarco copper smelter and contaminated soil over a large area of Puget Sound.

1. Contractors prepare the site for digging.

The Soil Safety Program provides free soil sampling and cleanup for play areas at schools, childcares, parks and camps. Vassault Park is the largest cleanup in the program, at eight acres. Cleanup happened quickly, driven by the need to plant and establish grass before the winter weather.


2. Contractors remove the top 6 to 12 inches of soil.
Over the years, Metro Parks Tacoma has also experienced drainage issues in the playfields at the park. Both Ecology and Metro Parks were glad to break ground this summer on this $2.1 million joint project to replace soils and fix the drainage problems.

 

How did Ecology clean up the 8 acres of soil in just a few months?

To give you an idea of how we completed the cleanup work, here's what happened from June to November 2014:

3. Contractors replace the soil with clean soil.
1) In June 2014, contractors did the following to prepare the site for digging:
  • Installed a chain link fence and high-visibility orange fence around the playfields. The fences marked the closed areas and kept park visitors out of the construction zones.
  • Brought equipment to the site and set up a staging area. 
  • Posted signs to inform park visitors of the construction schedule for the park.
4. Metro Parks Tacoma fixes past drainage issues.
2) From July to mid-August, contractors dug up the top 6 to 12 inches of contaminated soil and hauled it to a landfill. Since the cleanup spanned 8 acres, the contractors removed the soil one quadrant at a time. This photo shows the park after excavation and before new soil was backfilled.

3) Next, the contractors began backfilling the excavated areas with new soil. The top soil they used for the playfields was a mix of sand and compost. This mix is best for sports fields because it helps with drainage and is easy to maintain.

They also created a slight slope from the center out to the edges of the fields. The purpose of this is to drain water off the fields during the wet season.

4) To fix past drainage problems, Metro Parks Tacoma coordinated improvements on the east side of the playfield. After backfilling the topsoil, they excavated trenches and installed a network of drainage pipes every five feet. These pipes are buried 12 inches deep to avoid accidental damage.

5. Landscapers restore the lawn and playfields.
5) Finally, landscapers restored the lawn throughout the park. To make sure there's good grass coverage for sports, they completed the following steps:
  • Drill seeding the lawn, a process that uses a small tractor that tows a planter to plant individual seeds to a shallow depth in the topsoil. This process provides an even seed distribution and thicker grass layer.
  • Installing sod around the sprinkler heads and in drainage swells.
  • Watering and fertilizing the new lawn.

Final steps through May 2015

  • Fences will remain up around the new grass until May 2015. Grass roots need time to establish before visitors can start using the playfields again.
  • Grand Opening Celebration! Ecology and Metro Parks Tacoma are plannng to host a grand opening of the park in early summer 2015. More information coming soon!

Tacoma Smelter Plume: Work begins Monday to clean up contamination and improve drainage at Vassault Park

By Diana Smith, Public Involvement Coordinator, Toxics Cleanup Program

On Monday, Ecology’s Soil Safety Program will begin construction work to replace contaminated soils at the playfields at Tacoma’s Vassault Park. The former Asarco Tacoma smelter contaminated 1,000 square miles with arsenic and lead from its smokestack.

Metro Parks Tacoma will coordinate drainage improvements during the cleanup work. Doing these needed improvements during cleanup work is more cost-effective.

Construction schedule and closed areas

On Monday, June 30, our contractor will begin putting up fencing and moving equipment to the park. Work will run through mid-October.

The playfields will remain closed until summer of 2015 to protect the new grass and allow time for it to grow.

The tennis courts and playground will remain open throughout the project.

A big year for Everett Smelter cleanup

By Meg Bommarito, Everett Smelter Project Manager, Toxics Cleanup Program 


First, we take soil samples
Ecology has a lot of work planned for 2014 in the Everett Smelter cleanup. If you are in the cleanup area, you will definitely see us and construction crews doing a wide variety of work. Read below for details of our work. You can also meet us in person during a public meeting starting at 6:30 p.m. on Wednesday, March 11, at Snohomish County PUD Auditorium to learn more about what is going on with the cleanup.


Lowlands interim cleanup

We have been putting together a clear picture of where contamination is impacting the lowland site. Arsenic is contaminating deep groundwater, and to find the source of contamination, we are planning to dig up a small area in the Lowlands along East Marine View Drive. Before we do any digging, we are seeking your input on the scope of work for this interim cleanup. A public comment period will run from February 20 to March 24. To learn more, see Lowlands Interim Cleanup. If you have any comments, please send them to Sandra Matthews at Sandra.Matthews.@ecy.wa.gov. 


2014 residential cleanup

The photos at right show examples of the kind work we are doing at residential properties. This year, we will be cleaning up 20 properties on 6th, 7th and 8th streets between Winton and Wayne avenues. We expect cleanup construction will start mid- to late summer. We will keep you posted as more details on the construction schedule become available, at the Residential property cleanup website. 

Then, we dig out the contaminated soil

Residential and park mapping and Sampling

To prepare for future years of cleanup, we are undertaking a large soil sampling effort this summer. We plan to sample over 100 properties, which will allow us to determine which residential properties are cleaned up over the next few years. If your property has been selected to participate in this year’s sampling effort you should have received an access agreement request in the mail in January. We are also sampling the overlook area of American Legion Memorial Park. The rest of the park was sampled in 2012. 
Then, we add good soil and rebuild the area


American Legion Memorial Park cleanup

In November, we will begin removing contaminated soil at the American Legion Memorial Park. This effort will likely continue through April 2015. We will share more information as we move forward with this work. If you have any questions or want more information about the cleanup, please give us a call at 425-446-1024.

Learn more about the work planned for this year at a community meeting from 6:30 to 8:30 p.m. Wednesday, March 11, at the Snohomish County PUD Auditorium at 2320 California St. in Everett.

Tacoma Smelter Plume: Soil cleanup in progress at Tacoma parks

By Hannah Aoyagi, Toxics Cleanup Program

Loading soils into a truck to send to the landfill (Jane Clark Park).
Scraping off the top layer of soil from Jane Clark Park in Tacoma.
Ecology's Soil Safety Program is spending the summer at several parks, cleaning up arsenic and lead soil contamination from the old Tacoma Asarco smelter

The largest project is at Jane Clark Park in north Tacoma, where we will remove and replace 2.2 acres of soil! 

Other projects include finishing some soil replacement at Titlow Park in west Tacoma, and finishing last fall's work at American Lake in Lakewood.


Why do park work in the summer?

Unfortunately, construction season in the Pacific Northwest overlaps with summer break.  To keep our cleanup work from interfering with summer camps and sports, we work with local park districts as we plan each project.  We have also spaced cleanups out over several years so we don't have too many parks under construction in the same area.

How can I find out what's in my own yard?

Depending on where you live, you may qualify for free soil sampling, or we might already have sampling results for your yard. You can search your address on our interactive map to see if you live in an area that could have soil contamination.

Tacoma Smelter Plume: Fall park cleanups wrap up

By John Zinza, Field Coordinator, Toxics Cleanup Program





Dockton Park, Vashon Island
Fencing will remain until the grass is established
Just in time for the rainy season, park soil cleanup work wrapped up last week.  We cleaned up over two acres of play area, removing 2,846 cubic yards of contaminated soil—enough to fill 150 truck loads!
Parks completed:
  • Dottie Harper (Burien)
  • McMicken Heights (SeaTac)
  • Sunset Playfields (SeaTac)
  • Lake Grove (Federal Way)
  • Dockton (Vashon Island)

Getting to the "root" of the problem at Lakewood parks

During the start of cleanup activity at American Lake, we ran into tree roots after removing the sod. Trees can easily be harmed by moving the soil around their roots. We stopped work and capped the area we disturbed.  We are looking into capping the rest of the play area at American Lake, instead of doing any more digging.

Out of concern for root damage, we cancelled work at Kiwanis Park. This winter, we will explore our options for Kiwanis, including capping. We expect to finish the work in 2013.

Tacoma Smelter Plume: What park cleanup looks like

By John Zinza, Field Coordinator, Toxics Cleanup Program

We're on week two of our schedule for cleaning up contaminated soil at seven parks and making good progress.

This work is part of the Soil Safety Program, which cleans up park, school, childcare, and camp play areas contaminated by air emissions from the old Asarco smelter in Tacoma.

To give you an idea of what our program looks like, here is a series of photos from Dottie Harper Park in Burien...

Under the play structures did not need any cleanup, but children also play in the surrounding grassy area. We dug up the contaminated soils and this picture shows the new soil we put in, all ready to be seeded with grass.


Digging up contaminated soil around a popular sculpture.


We don't normally clean up wooded areas of parks because digging can damage trees. In this case, kids often use the slide (on the right edge of the photo). There is a lot of exposed dirt, so we covered it with bark to reduce possible exposure.


The bark is all finished. The slide in the background has a black fabric liner underneath and will soon be getting play chips. The play chips look different and are better for fall protection than the landscaping bark you see here.

Tacoma Smelter Plume: Park cleanups underway this week

By Hannah Aoyagi, Tacoma Smelter Plume Project, Toxics Cleanup Program

The Soil Safety Program will be busy this fall season, cleaning up play areas at seven parks in a six week span.  We are removing soils contaminated with arsenic and lead from the former Asarco smelter in north Tacoma.

The parks are:
  • Dottie Harper (Burien)
  • Sunset Playfields (SeaTac)
  • McMicken Heights (SeaTac)
  • Lake Grove (Federal Way)
  • Dockton (Vashon Island) - pictured here
  • American Lake (Lakewood)
  • Kiwanis (Lakewood)
While the arsenic and lead levels we have found at parks do not pose an immediate threat, there is a long-term risk, especially for children. For more information about contaminated soils and risk, see our blog post on Dottie Harper Park from earlier this year.

Why clean up only the play areas at parks?

Play areas are generally where children spend the most time.  We talk to parks staff about where they see kids playing and coming into contact with dirt.  So, a "play area" could be the dirt under picnic tables or a grassy field next to the playground.

Also, for many parks, the space outside of the designated play areas is wooded.  Because soil removal damages tree roots, we can't do much cleanup in the woods.  It's okay to play there.  We just recommend healthy actions like washing hands after playing in the dirt, and taking off shoes before entering the house. 

More about the soil contamination...

Read our news release about the park cleanups.  Visit the Tacoma Smelter Plume website for more information about the 1,000 square mile area impacted by air emissions from the former Asarco smelter.

We will post more blogs on our cleanup progress and other Tacoma Smelter Plume work!
