The emergence of biofuels in the energy supply brings some new challenges and precautions to bear. Progress both in the field and lab on biofuel biodegradation shows how apt these leaks may be to develop methane concerns. This session will explore the unexpected behavior of ethanol over time at three Midwestern rail spills. Data arriving from bench studies on decay for several biofuels are analyzed, and we'll look at ways to use ground water monitoring wells to sample soil gases. This session has much to offer on the cautions inherent with these new fuels.

Cathodic protection is one of the more complex and sometimes confusing areas of the UST regulations. This session will allow inspectors to share experiences and learn from other states. First we will hear two different states’ experiences with impressed current (rectifier) systems: Kansas’ requirements for rectifier log review stemming from a fire; and Utah’s experiences with tanks that use statistical analyses to justify the use of impressed current CP. We will then switch to galvanic (sacrificial anode) CP with an overview of the Steel Tank Institute’s Recommended Practice for the Addition of Supplemental Anodes to sti-P3® USTs. Plenty of time will be incorporated for questions and information sharing.

This session will provide information on vapor intrusion of petroleum hydrocarbons. The session will start with a summary of the current status of EPA's petroleum vapor intrusion guidance. Next an overview of the lessons learned from approximately 90 soil gas sampling case studies in Tennessee will be provided; the overview will then be complemented by a detailed vapor intrusion case study on a residential property in Virginia. The final presentation will evaluate several vapor intrusion sampling methodologies. Active and passive sampling approaches will be compared. Since active (pumped) sampling can pull up vapors from more contaminated deeper soils, the potential for overestimation of benzene concentrations will be discussed.

Despite advances in UST equipment design and materials, many releases continue to occur due to spills and overfills during delivery. Spills during delivery usually result from human error and can be avoided if everyone involved in the fuel delivery understands equipment limitations and follows industry standard practices for tank filling. Periodic visual inspection of spill prevention equipment including spill buckets, overfill prevention devices, sumps and secondary containment, can go a long way towards spill prevention. This session will begin with a presentation on spill buckets, one of the weakest components of UST systems and a primary source for releases. The next presentation will focus on overfill prevention devices and their functionality, followed by a presentation on spill prevention problem areas often identified during compliance inspections.

The phone rings. There's fuel seeping through cracks in the pavement at a truck stop. What do you do? You order the owner to shut down his tank system and hire an environmental response team. You require line and tank tightness tests before you let the owner operate again. But when the emergency is over, do you really know exactly what leaked and why? And do you have information that will help prevent similar leaks elsewhere?

UST regulators, inspectors, and fund managers will benefit from this lively session. You'll get real-life, practical advice on how to better identify the "sources and causes" of leaks; how to improve your Leak Scene Investigations; how to work with owners, contractors, equipment manufacturers and testing labs to identify what leaked and why; and how to use those insights to improve your regulatory program.

Light Non-Aqueous Phase Liquids (LNAPLs) have been a driver of corrective action since the beginning of the national tanks program. Most States have regulations that describe corrective action to recover LNAPLs "to the maximum extent practicable". It's been almost 25 years since it all began. What is the State of Art in LNAPL recovery? What is the current thought on the behavior of LNAPL in the subsurface? Is it time for us to revisit our regulations and approaches to conducting LNAPL corrective action? All this and more will be revealed by three speakers discussing a study of LNAPL plume stability, describing the latest in LNAPL conceptual site model application for remediation selection, design and determining remediation endpoints, and describing an innovative technology for addressing LNAPL remediation.

With state and federal mandates encouraging the increased use of biofuels in our fuel supply, one of the key issues for many UST programs has been whether or not existing UST system equipment is capable of handling these new fuels. In particular, leak detection equipment is not tested with biofuels, which have different properties than petroleum, and may affect operability. In this session, panelists will discuss the effects of biofuels and biofuel blends may have on leak detection equipment, and describe the status of testing being done to ensure existing equipment can handle increased biofuel blends. A member of the National Work Group on Leak Detection Evaluations will also discuss a proposal to accept up to 20% biodiesel blends under the current protocols.

Why, sometimes, do leaks seem like nightmares; able to evade all efforts to keep them at bay? It may be that the devil lies in the details. John Wagner probes some technical points with CSLD, looks for clues from SCRs, and argues why operator training is paramount to find leaks hidden from ordinary inspections. Study a case with Bob May to learn why large product loss occurred at his site with the ELLDs in full compliance all the while. Owners and regulators willing to go a bit beyond the norm may avoid their worst nightmares by attending this beneficial session!

This session will start with a side-by-side evaluation of various in-situ chemical oxidization (ISCO) materials currently used to remove BTEX and GRO compounds from soil and groundwater. Speakers will evaluate costs of various ISCO approaches for use in a range of contaminant concentrations, and compare these costs to other available remedial technologies. Case incidents of specific sites will be presented where ISCO was implemented as the primary remediation alternative. The second presentation provides an overview of a project in Kansas where a BTEX/EDB plume was successfully remediated using soil vapor extraction and air sparging. This talk will discuss the assessment and remediation phases of the project, including remediation system design criteria, and system costs and performance. The final presentation describes the results of MTBE and TBA degradation under field conditions at several sites in Maryland following implementation of Delta’s Sulfate Enhanced Biodegradation (SEB) process. The SEB process utilizes magnesium sulfate applications. Final SEB treatment results and associated implementation costs from field applications will be presented.

The Underground Storage Tank program has cleaned up almost 400,000 sites in its relatively short history, yet the program is still evolving. As leak prevention methods stem the tide of incoming cleanup sites and pressures to achieve cleanups are increasing, state programs are compelled to find innovative ways to investigate their cleanup backlog and complete cleanups. To do this, a useful concept to employ is the progress a release makes through the various stages of cleanup. Over the last two years, OUST has been pursuing a study using detailed information from 14 States to understand the pace of LUST cleanups, including what stage of cleanup they are in, and to explore strategies, in partnership with States, to continue and accelerate such cleanups. This session will look at the stages of cleanup from regulatory and industry perspectives and will include a discussion of why releases might get “stuck” along the way. OUST will present the results of their study and facilitate an open discussion on the collaborative effort of working with States and Regions to develop and implement backlog reduction strategies.

With concerns about the impending "blend wall," EPA is considering the use of mid-level ethanol blends such as E15. Many legacy UST systems, however, may be comprised of some components which were only designed and tested to accommodate ethanol blends of up to 10%, and little compatibility data exists for these materials. How will E15 affect these existing tank systems? In this session, panelists will discuss the status of materials testing being performed with mid-level ethanol blends, as well as the new issues this fuel blend may raise for station owners and regulatory agencies.

Regardless of how you approach the money question, the answer typically involves using some sort of algorithm to calculate an average site cleanup cost and applying it to all open sites. Calculating the average site cost is critically dependent on the assumptions made, and can vary widely. Understanding the limitations behind the average site cleanup cost number is critical to understanding what your Fund liabilities truly are. In this session, we will explore many of the key assumptions and conditions that can dramatically affect the calculation of the “average” site cleanup cost. We will then examine this topic from an actuarial perspective and learn how your view of your Fund's liabilities may clash with an actuary’s view.

Accurate and complete site assessment is critical to remediation. New methods are being developed to reduce costs and provide detailed information to speed closure. This session will explore:
- Remote sensing using continuous imaging processing of electrical resistivity data to optimally place LNAPL recovery wells.
- Impacts of changes in gasoline composition, including lead scavengers, ethanol, and the pending nationwide reduction in benzene content.
- Computer modeling to correlate groundwater elevations to nearby stream flow measurements to predict the maximum depth of adsorbed hydrocarbons. Wells can then be installed deep enough to lower the water table and expose all impacted soil to SVE.
