Free
Release Survey Completed Chase completed a comprehensive free release
survey project for a major California university. The
Chase crew surveyed and released almost 120 cubic yards
of recyclables, scrap, and debris at the university's
central radioactive and hazardous waste handling facility.
Chase also surveyed and released several storage containers
and mobile offices.
The free release survey program was performed concurrently
with the MARSSIM Final Status Survey and Decommissioning
work we were conducting at the facility. This fixed price
project was completed on schedule and budget during the
rush period before Christmas.

Groundwater
Treatment System Improvements Chase
completed full-scale system improvements, including software
upgrades to a groundwater treatment system located at
a former lighting manufacturing facility. The work included
installing a 600 foot long groundwater collection trench,
installing mechanical and digital flow meters to the influent
lines as well as a wellhead air pressure regulator, and
upgrading the system's control circuitry and software
ISACC (Intelligent System for Automatic Control and Communication).
The system was designed to facilitate the extraction,
treatment and discharge of groundwater from on-site shallow
wells. The extracted groundwater is treated by a counter-current,
shallow tray, air-stripping unit. Chase also removed 600
tons of contaminated soil at the facility and managed
it as special waste for disposal.

Baseline
Radiological Survey
Chase completed a baseline
radiological survey for another large industrial client
in the Midwest. Chase's survey team performed detailed
beta and gamma radiation surveys at a facility with
several hundred thousand square feet of area to determine
baseline levels of radiation and radioactivity. Chase
used highly sensitive radiation detectors and laser
ranging to precisely locate and identify survey locations.

Superfund
Site Cap Repair
Chase completed repairing erosion damage to low permeability
caps on a Superfund site. The work entailed clearing,
grubbing, and removing surface debris to prepare for the
installation of concrete infilled Geocells, geosynthetic
liners and HDPE liner systems. The project included detailed
surveys and precision excavation of damaged areas prior
to installing the improved drainage channels.
Nov

Chase
and subcontractor personnel used company-owned equipment
to perform compacting and contouring existing and borrow
material to grade specifications, placing erosion matting,
and installing the final layers of concrete and infilled
Geocells.

Environmental
Management at a Historical Building Renovation
Chase completed a project to abate and manage environmental
concerns associated with the remodeling and refurbishment
of a historical property in Madison, Indiana. The work
included: testing, mobilization, removal of piping and
fittings and associated Asbestos Containing Material (ACM),
demolition and removal of boilers and associated ACM,
removal of ACM floor tile, decorative ceiling removal,
removal of the underground heating oil tank, collection,
inventory and proper disposal of loose chemical and electrical
material hazards (mercury bulbs and PCB ballasts) and
the removal / disposal of building trash and loose materials.
Chase also performed activities to remove the fungi Stachybotrys
chartarum from the building.

Chase
has been awarded a contract for decommissioning a tritium-contaminated
bunker used for storing explosives. Chase was awarded
the decommissioning phase of a contaminated explosives
bunker in the south Texas area. Chase will propose a MARSSIM
approach to the State of Texas in what will be a precedent
setting decommissioning effort.

Asbestos
Abatement
Chase performed asbestos abatement at a major Midwest
university facility undergoing a large-scale renovation.
The work included removing nearly 700 lineal feet of 12-24
inch in diameter transite from piping at the university.
Chase performed all the clearance and personal asbestos
monitoring for the project.

Chase
has added a new piece of equipment to our extensive inventory
of field services equipment. Chase took delivery of a
new CME-55 drill, mounted on a 2001 FL70 Freightliner
carrier. This drill is equipped with a High Torque Rotary
Drive, a 26 foot mast, one 7,000 pound and two 3,200 pound
hydraulic hoist, a Moyno 3L6 water pump and a 140 pound
automatic SPT hammer. This unit will help us keep pace
with the growing demand for geotechnical investigations
and well installation.

Chase
was awarded and completed a contract for decontamination
of Am-241 Foil Manufacturing Facility in the Midwest.
In October, Chase mobilized a team of decontamination
technicians, health physics experts and transportation
specialists to a facility to assist in a decontamination
and decommissioning effort. The Chase team successfully
reduced levels of loose contamination to less than the
guideline limits of the decommissioning plan. Chase also
assisted the customer in the removal of waste materials
to Alaron, our teaming partner’s processing facility in
Wampum, PA. The pace of the project was accelerated due
to the tight decommissioning timetable, and our portion
of the work scope was completed two full days ahead of
schedule and on budget.
Oct

Chase
was awarded a contract to perform groundwater cleanup
at a major university. Chase installed our VAMPIRE (Vacuum
Assisted Multi-Phase In-situ Remediation Equipment) at
a facility to extract subsurface volatile organics from
a contaminated aquifer. Chase’s unit efficiently removed
large volumes of pure product from the groundwater, eliminating
the need for an expensive and time consuming pump and
treat approach.

Chase
Completes Portsmouth Gaseous Diffusion Plant Soil Project.
The partnership of Chase Environmental Group and the Alaron
Corporation along with MHF Logistical Solutions, completed
the PGDP Soil Moisture Absorption Project. The last of
the waste was processed during the first week in October.
The last of the railcars full of processed waste has been
accepted for disposal at Envirocare of Utah. Wastren,
Bechtel Jacob’s waste contracting firm for the Piketon,
Ohio facility, issued the contract for project to Alaron/Chase.
Plans are currently underway for continuing work on similar
waste streams.

Chase met the first
milestone of an aggressive schedule to decommission
a facility in California used to store and treat hazardous
and radioactive waste. The project involved developing
and implementing decommissioning and final status survey
plans using MARSSIM's guidance. The California
DHS, with no comments, approved the first phase Plan
and Report. This paves the way for the second
phase of the decommissioning scheduled later this year.

Chase's
re-vamped Brokerage Services Division has also been awarded
a contract to manage and dispose of high-activity IR-192
with a significant amount of Co-60 impurities. The
seeds will be stored for decay of the IR-192 at a Facility
in Wampum, PA, operated by Alaron, Chase's teaming partner.
Once the decay is completed, the seeds will be stabilized
and disposed of at Barnwell.

Chase
Environmental Group has been awarded a contract to remove
mixed waste sludge from a facility in the Midwest. The
mercury and Am-241/Cs-137 contaminated sludge will be
stabilized by ATG in Richland, WA for stabilization and
disposal at Envirocare of Utah.
Aug
2000
Chase's
Radioactive Field Services Division has been awarded a
contract to remove radioactive waste and perform characterization
surveys of an accelerator laboratory in one of the southern
tier states. These activities will be conducted in advance
of a future license termination activity tentatively scheduled
within the next two years.

With
a week to spare, Chase Environmental Group and teaming
partner Alaron have completed the first milestone of a
large volume processing project by processing and disposing
of the first 20% of over one thousand boxes of waste.
By the second week in August , the project team had crossed
the half-way point. The process involves adding absorbent
materials to filter cake that had been originally loaded
into B-25 and larger boxes. The waste materials are dumped
into mix bins designed by Chase using a box dumping device
designed by Alaron. A Chase operator then adds lime kiln
dust to the bins and mixes the matrix with a track-hoe.
When sufficiently mixed, the waste is loaded into a burrito
wrapper lined gondola rail car (provided by MHF/LS) and
shipped for disposal at Envirocare of Utah.
