 EPA will remove asbestos and hazardous substances in drums and containers.
 EPA, in November 2008, began an assessment of potential risks to human health in response to public concerns regarding the
 vacant mill building on South Street, as wel) as soil on an empty lot adjacent to the Neponset River. EPA completed this assessment
 work in March 2009 and determined the need for a short term cleanup separate from those previously announced for the
 Blackburn and Union Privileges Superfund Site.
Ov
era)I Site Status
After considerii>g public comments, in
September 2008 EPA decided on an
overall site cleanup plan. The cleanup
plan indudes these major components:
removal of Neponset River and Lewis
Pond contaminated sediment; cleanup
of contaminated on-site soil; cleanup of
on-site groundwater which could pollute
local surface water; restriction on future
uses of the South Street on-site proper-
ties. EPA is currently negotiating with the
potentially responsible parries that owned
facilities and or operated at the site for
die performance of the cleanup work.
Site History

The Blackburn & Union Privileges site
located in Walpole, MA was added to the
Superfund National Priority List in 1994.
Industrial and commercial processes on
the site date back to the 1600s. Between
1891 and 1915, the site was used for
manufacture of tires, rubber goods, and
insulating materials. The crushing of raw
asbestos in die manufacture of brake and
clutch linings occurred at the site between
1915 and 1937. Various cotton and fabric
production processes were conducted at
the sits from 1937 until 1985.

                                  or pulverized) asbestos,
                                  asbestos-containing
                                  material, and drums and
                                  containers containing

                                  compounds (VOCs),
                                  semi-volatile organic
                                  compounds (SVOCs),

                                  in disrepair, and there
                                  is no fire suppression

                                  ers are a health threat
                                  to anyone on the site
                                  and may pose additional
                                  risks in the event of a
                                  fire. Found at the unsecured vacant lot were
                                  discarded brake pads and asbestos contain-
                                  ing soil which also pose a health threat to
                                  anyone on the lot. Due to the threat to
                                  human health and the environment, a short
                                  term cleanup action  under EPA's Superfund
                                  removal program is warranted.

Removal Actions
The removal action, conducted by EPA's
contractor with EPA oversight, will begin
in June and continue through the summer.
                 Work will occur daily
                 from 7:00 am to 6:00
                 pm, Monday through
                 Friday. As part of the
                 removal action, neigh-
                 bors  will see workers
                 securing the site to
                 prevent unauthorized
                 access. Such efforts
                 may include staffed site
                 security during non-
                 working hours.

                 Former Mill
                 The former mill build-
                 ing has been found by
                 EPA to be structurally
                 adequate. All visible
                 friable asbestos and
                 asbestos-containing ma-
                 terial will be removed.
To prevent any air-borne asbestos from
escaping during the cleanup, the building will
be sealed.The asbestos material removed
from the building will be stockpiled until the
work is complete, at which time it will  be
trucked in sealed containers to a licensed
landfill.The abandoned drums and contain-
ers will  also be removed and disposed  of at
a licensed facility.

                     Using a small excavator, workers wearing
                     respirators and white protective suits will
                     dig test pits to determine if asbestos is
                     located in the soil of the vacant lot Should
                     asbestos be found within the soil, it is likely
                     that a certain portion of the soil will be
                     removed  and then back filled with clean soil.
                     Any contaminated soil which may remain
                     at depth or which can't otherwise be safely
                     excavated will be capped.


                     Air Monitoring

                     EPA will be conducting air monitoring
                     throughout the removal effort to ensure the
                     safety of its workers and the surrounding
                     community.
Lewis Pond

Based on sampling performed, EPA deter-
mined that the contaminated sediment
originating at the Blackburn & Union
Privileges site has  been carried down-
stream by the Neponset River and settled
to the bottom of Lewis Pond.
The site's long-term cleanup plan does ad-
dress the contaminated sediment within
Lewis Pond. In the interim time before
long-term work gets underway, residents
should continue to avoid contact with
Lewis Pond sediment.
