Sam Houston Electric Cooperative (SHECO) Transformer
Recovery/Remediation
CCI was contracted to assist SHECO in the recovery and remediation of
PCB contaminated transformers and non-PCB contaminated
transformers. During Hurricane IKE SHECO’s power grid received
significant damage. SHECO still had a low percent of its
pole-mounted transformers that were suspect PCB containing. CCI
set up a staging and collection area for the assessment and sampling of
transformers as they were picked up by CCI. The first priority
was to comb the entire system for transformers damaged and left on
sites for pickup. The transformers were GPS located, assessed for
type and contamination, spills were located and marked, pictures of the
transformer and the spill were taken, and then the transformers
packaged and load on a transport vehicle. The transformers were
then taken to the collection area and given a unique number. If
the transformer was suspect it was sampled for confirmation. Once
the samples were returned the transformers were tagged and segregated
for disposal. The soil was remediated in accordance with the
sample results and/or assessments of the transformers. If the
transformer contained PCBs the excavation had confirmation samples
taken prior to backfilling. The soil was segregated in containers
for disposal. CCI provided all FEMA Recovery documentation for
SHECO.
F5 Tornado Hazardous Waste Cleanup; Del City
and Grady County, OK
CCI responded after an area involving 700+ residential structures
was destroyed by an F5 tornado. The area was contaminated due to
the hazardous waste from households and other structures that were
in the tornado's path. The storm passed through Tinker AFB and a
heavily industrialized section of Oklahoma City just prior to
striking Del City. CCI developed a response plan that included
environmental monitoring and remediation plans. Public access areas
were cleared using a "hazmat sweep" to remove all containers and
identify areas of release. These areas were evaluated and
remediation methods were determined. Methods varied from on-site
treatment to excavation. As property owners authorized
right-of-entries, CCI completed a sweep of the residential
properties and removed all hazardous wastes. Remedial activities
were carried out using the same methodology as with the public
access areas. As the waste was removed and remediated, it was taken
to a temporary storage area. CCI set up the site and developed the
security and monitoring plan. The materials were segregated and
stored in covered roll-off containers. The project continued over a
period of six weeks and accounted for over 3,000 man-hours. More
than 40,000 pounds of waste were collected during this project.
Ice Storm Response; Lowell, Mt. Holly, and
Ranlo, NC
CCI was contracted by Asplundh Environmental Services (AES) to
assist with the operation and management of a temporary debris
storage and reduction site used by the City of Lowell, the City of
Mt. Holly, and the Town of Ranlo. AES was awarded the contract to
remove debris generated from the massive ice storm that struck the
region in December 2002. AES and their clients identified the need
to establish methods to reduce the amount of material that would be
disposed of at the municipal landfill, subsequently decreasing
valuable airspace. The reduction method identified for utilization
was burning by air curtain incineration. Through burning, at least a
97% reduction could be accomplished leaving only 3% residual ash
requiring disposal. CCI mobilized the necessary personnel and
equipment to process and reduce approximately 18,000 cubic yards of
vegetative debris. Although there were shutdowns due to adverse
weather conditions, CCI maintained a vigorous production rate and
completed this project on time. Additionally, DEHNER had shut down
many burn operations in the surrounding area but the CCI site was
allowed to continue. Upon completion of burning operations, CCI
personnel returned the site to nearly its original condition.
Hurricane Katrina Response; Keesler Air
Force Base, Biloxi, MS
In Stage One, CCI sent in a small strike team to set up a temporary
decontamination area, search through the buildings to locate major
problem areas, and started general collection and staging of
materials. The Team – comprised of a supervisor and three
technicians – was on site within 48 hours of Notice to Proceed. The
Team spent three days on site performing reconnaissance, site
set-up, and high hazard removal in areas where chemical mixing was a
threat. In Stage Two, CCI mobilized a larger crew and equipment to
continue with material collection and removal. Debris and other
materials were removed from the buildings using skid steer loaders
with grapplers to gain access to chemicals. A mini excavator was
used to render the debris materials unusable. Chemical-type
materials were removed from the buildings by personnel using carts
and buckets to a staging area. Another contractor at the staging
area worked on packaging, transportation, and disposal. This crew
included one supervisor, one safety officer, two foreman or lead
technicians, three operator technicians, and at times had between
six and eight technicians. All supplies for EPA Level C response
were supplied along with necessary equipment to carry out the above
tasks.
Hurricane Floyd Hazardous Materials Cleanup;
Kinston, NC and Myrtle Beach, SC
CCI responded after Hurricane Floyd swept through regions of
North Carolina and South Carolina, causing devastation for miles.
The Neuse River flooded the banks of Lenior County, causing
widespread petroleum contamination and other hazardous waste
issues. CCI was tasked with assessing the situation in Lenior
County and providing containment activities to keep the
contamination within the areas of origin. CCI used aerial views and
GPS positioning to identify problem that included two large salvage
yards, a chemical storage facility, petroleum tank farms,
agricultural supply areas, and several unknown sheen areas already
in the flow of the Neuse River. CCI was assigned the task of
stopping the flow of contamination in the River and containing the
fixed site contamination to the site of origin. CCI accomplished
these tasks by placing more than 10,000 feet of boom around the
fixed facilities noted by GPS. This task was accomplished both from
the banks with personnel properly protected from the elements and
from CCI- supplied water vessels.
