Tex
Tin Superfund Site
Texas City, TX |
Description:
140-acre former tin smelter
Regulatory Jurisdiction: EPA Region 6
Problem: Historical WWII site with controversial past
and high profile. Was largest tin smelter in the world during WWII. Technically
complex “poster child” Superfund site (acid pools, As-impacted
catalysts, wastewater pools, NORM piles, dilapidated buildings).
PNL Role: Developed a fast-track, streamlined Design/Build
approach. Approach saved $10MM. Project schedule was reduced by 5 months.
Worked to build excellent relationship with City and EPA. Tailored area
by area remedy, where solution matched long-term development goals.

Malone
Superfund Site
Texas City, TX |
Description:
150-acre former petroleum waste facility
Regulatory Jurisdiction: EPA Region 6
Problem: On-site structures include numerous above ground
storage tanks, a large earthen surface impoundment, concrete-lined separators,
two underground injection wells, and rolloff bins. The entire waste management
facility is surrounded by a flood protection-levee and is bordered on
the northeast and east by swamp/marsh lands which extend to the shore
of Swan Lake and Galveston Bay. The two sources of contamination on the
site are the settling basin surface impoundment/earthen impoundment and
oil pit.
PNL Role: Project Navigator is the project coordinator
and is currently managing all aspects of the RI/FS at this complex site.
In particular we are overseeing the collection of appropriate data to
perform a focused risk assessment. Our responsibilities also include the
management of all associated workplans.

PAB
Oil & Chemical Service, Inc.
Superfund Site
Abbeville, LA |
Description:
9.4-acre oilfield waste disposal facility
Regulatory Jurisdiction: EPA Region 6
Problem: Three onsite pits were used to separate oil,
water, and solids. The site is surrounded by a leaking levee rising 6
to 7 feet above the general grade. An estimated 39,000 cubic yards of
oily sludge are held within the levee. Samples detected barium, chromium,
lead in sludge in the pits.
PNL
Role: This former oilfield waste facility has undergone remediation.
Project Navigator has reduced the scope of O&M, successfully challenged
approximately 40% of EPA's response cost bills.

MAR
Services Oilfield Site
Cankton, LA |
Description:
80-acre former oilfield waste disposal facility
Regulatory Jurisdiction: DNR-lead
Problem: Large site with salt and Ba and As impacts.
Soil volumes exceeding regulatory criteria were in excess of 250,000 cu.
yds. Prohibitive remediation costs to rigorously meet criteria.
PNL Role: Risk-based remedy. Worked diligently with DNR
to limit remediation to 3 feet depth for salts and most metals. $10MM+
in cost savings. Shaved 24 months from original schedule.

Cox
Road Landfill Site
Liberty County, TX |
Description:
80-acre former industrial solid waste landfill
Regulatory Jurisdiction:
Problem: An abandoned landfill site, located in rural Liberty County, became a concern after residences were developed on nearby former agricultural land. Oily filter cake and sludge at the surface is exposed at the site because of erosion of the landfill cover. The potential for surface water and groundwater impacts needs to be investigated.
PNL Role: PNL is working to coordinate closure of the site under the State Voluntary Cleanup Program and move the project forward to closure. The approach is to build consensus with the State and Responsible Parties for site closure using the risk-based Texas Risk Reduction Protocol.

Patrick Bayou Superfund Site
Deer Park , TX |
Description: 3 mile long bayou with impacted sediments
Regulatory Jurisdiction: EPA Region 6
Problem: Patrick Bayou is located in a mixed urban, highly industrialized petrochemical area in southeast Harris County approximately 1 mile north of Deer Park, Texas. Most of the upper portion of the Bayou consists of a series of open, concrete-lined storm water channels and large metal/concrete culverts. These structures were installed to receive storm water runoff and permitted wastewater discharges and for erosion control. Contaminated sediments have been documented within the bounds of Patrick Bayou originating below a series of culverts. Previous investigations confirmed the presence of the following chemicals in Patrick Bayou sediments: metals, PAHs, PCBs, dioxins/furans and others.
PNL Role: Project Navigator is the Project Coordinator for a multi-party PRP Group at this site. A PNL associate was retained in 2003 to coordinate the PRP Group's efforts. Our initial efforts were to assist the Group in AOC/SOW negotiations for the RI/FS and in selecting the RI/FS contractor. The RI/FS is ongoing and PNL provides oversight of the RI/FS and various specialty sediment, hydrodynamic, and risk evaluation contractors for the project. PNL is the primary interface with EPA, the state and other stakeholders. The project utilizes Adaptive Management Strategies to rapidly respond to new information on site conditions. PNL also manages the project budget for the Group.
