-------
Reclamation A-l Lumber
In an effort to develop prime Anaconda real
estate, 8.5 acres at the A-l Lumber site have
been stripped of waste and contaminated
soils and replaced with clean-fill.
EPA and Anaconda-Deer Lodge County
targeted cleanup at the site to promote
redevelopment opportunities such as a new
Montana Veterans Center.
The contaminated
soils and waste from
the A-l Lumber site
were hauled to the
Atlantic Richfield
Land Management
Area (A-9 waste cell),
formally known as
Opportunity Ponds.
After placing clean fill at the A-l Lumber
site, Western Reclamation, Inc. of
Anaconda performed the vegetation work.
They added compost to the clean fill and
good seed germination can be seen at the
site.
FOURTH FIVE -YEAR REVIEW
A five-year review is performed wherever final
remedies allow contaminants to remain in place. A
significant part of this five year review focused on
vegetation assessments conducted on capped or treated
fl| soils. Good vegetation is present in the capped Old
Works floodplain adjacent to the historic Red Sands
area. The five year review identified some concerns
about the performance of the remedy. These concerns
include erosion from steep slope areas onto the Old
Work Historic Trail and from unauthorized motor
vehicle access in
the Old Works
Historic Area,
where high levels
of arsenic are «
known to exist.
'.-,*.
Community Soils
Most remaining work in 2010 consisted of residential
yard cleanup outside of Anaconda, such as the Aspen
Hills area. Soil sampling determines the depth of
soil removal. Contaminated soils and mine wastes
are excavated and hauled to the Atlantic Richfield
Land Management Area.

Rock caps and retaining walls prevent
contaminated sediment from reaching
city streets during storm runoff.

Wildlife Occupying Reclaimed Areas In Anaconda
EPA anticipates the same planting of approximately 34,322
shrubs and willows planted in 2010 for the spring of 2011. The
planting crew consisted of mainly Butte and Anaconda
residents.
East Borrow Area (EBA) Wetlands
The EBA wetlands are seeded with
transitional and wetland seed mixes.
The majority of the area is drill
seeded, and the saturated areas are
seeded by hand.
Moose, osprey, long-
billed curlews, Canada geese, antelope, sand-hill
cranes, deer, and many more animals have begun
to frequent reclaimed areas in Anaconda.
The wetland project is one of the largest ever performed in
the country. By August 2010, approximately 550,000
wetland plants inhabited the EBA. Through the 2009-10
period a total of about 1,850,000 plants were installed in
the EBA wetlands. The 2011 wetland planting schedule
will include the South Borrow Wetlands.
Milltown Sediments
Subsurface hydric soils have begun to develop as
evidence by the blue-grey color. Hydric soils favor
the growth and regeneration of wetland vegetation.
2010 should have brought new vegetation to the waste
repository where Milltown sediments are placed. EPA is
dedicated to understanding and providing a solution to the
scarcity on the Milltown sediments.
-------
Atlantic Richfield removed contaminated
soils from the Warm Springs Creek
floodplain in 2010. Additionally, they
seeded approximately 180 acres south of the
creek, and vegetation has started to sprout.
Stucky Ridge
Best management practices (BMPs), including silt
fence and straw bale dikes, prevent sediment
transport to the creek during storm events . The
temporary BMPs are put in place until strong
vegetation is established.
The Montana Department of Justice - Natural
Resources Damage Program assumed certain
remedial action responsibilities for portions of
Remedial Design Unit (RDU) 1 Stucky Ridge
and RDU 15 Mount Haggin under the 2008
Clark Fork River OU Consent Decree. A haul
road, built in the spring of 2010, allows
equipment access from the north side of
Stucky Ridge. Sugar beet lime, a waste '
product from sugar refining in Billings, is
added to the soil to neutralize acidity.
EPA expects construction to last three years. EPA
anticipates the same abundant vegetation as seen in the
demonstration plots on Stucky Ridge and the steep
slope stabilization at Nazer Gulch.
