Pre-Conference Workshops
Please see the descriptions below of the pre-conference workshops that will be offered at the 2012 National Tanks Conference. You can select a workshop when registering for the conference. Workshops are a reimbursable cost. Space is limited and on-site registration is not accepted.
Making the Most Out of Leak Detection Systems
Sunday, March 18, 1:00 - 3:00 p.m.
Join Mr. John Wagner as he reveals Automatic Tank Gauge's (ATGs) vulnerabilities to tampering, record keeping schemes, and easily employed techniques to defeat leak sensors. Using hands-on interactive demonstrations, Mr. Wagner will clearly explain how to make an ATG confess its secrets with a regulator's scrutiny and professional zeal. This workshop is a must see for any UST inspector.
Site Optimization and Land Revitalization Using Triad Approach
Sunday, March 18, 3:15 - 5:00 p.m.
This workshop will discuss case studies that demonstrate the use of the principles of Triad, including the use of innovative technology (MIP) as a real-time sampling tool and the innovative use of funding to cleanup a stalled site, which led to land revitalization. Sites to be discussed include the Fannon former petroleum bulk terminal that has been redeveloped for residential reuse in Alexandria, VA. In addition, sites in New Jersey that demonstrate the use of high resolution plume delineation and 3d visualization to optimize in situ remediation using ISCO and enhanced bioremediation compared to previously planned excavation that would have likely failed to meet clean-up objectives will be discussed as time allows.
Bio-Vapor Hands-On
Sunday, March 18, 1:00 - 5:00 p.m.
This workshop will start with a brief overview of petroleum vapor intrusion issues, conceptual models, and comparisons to chlorinated solvent vapor intrusion. That groundwork will be used to launch an introduction to the BioVapor Model for estimating the severity of potential petroleum vapor intrusion. The workshop will include a discussion of model fundamentals, selection of parameters, and model output, including BioVapor model sensitivity studies and comparisons with measured data. This workshop is a “hands-On” Case Study Exercise and Software Application of the BioVapor software tool.
The BioVapor model is a Microsoft Excel spreadsheet. Workshop attendees must bring their own (battery-powered) laptop computers loaded with their own Microsoft Excel software.
Biofuel Releases: Prevention, Investigation, and Remediation
Sunday, March 18, 1:00 - 5:00
This workshop is based on the ITRC technical and regulatory guidance document, “ Biofuels: Release Prevention, Environmental Behavior, and Remediation (Biofuels-1, 2011)” and associated internet based training. Participants will learn the scope of potential environmental challenges posed by biofuel releases by learning biofuel fundamentals, regulatory status, and future usage projections. Participants will learn the differences in biofuel and petroleum behavior in the environment; release scenarios, including potential release points within the biofuel supply chain, potential release frequencies, possible volumes, and likely media impacts. The workshop will explore biofuel release prevention measures; how to develop an appropriate conceptual model for the investigation and remediation of biofuels; and how to select appropriate investigation and remediation strategies.
Petroleum Vapor - Field Technical
Sunday, March 18, 1:00 - 3:00
The screening approach being developed by EPA OUST to evaluate petroleum vapor intrusion (PVI) requires information that has not be routinely collected in the past at vapor intrusion sites. What is the best way to collect this data? What are the relevant data quality issues and data quality requirements? How should the data organized and used to inform a decision? Have you ever wondered how this stuff really works? Here is your chance to see it demonstrated.
Instructors will demonstrate the operation of commercially available equipment that provides information on concentrations of oxygen, carbon dioxide, methane, and combustible gases in air. They will demonstrate the use of field meters to determine concentrations of oxygen, methane and carbon dioxide in the soil gas, as well as demonstrate the construction and application of traps packed with Granular Activated Carbon (GAC) to remove gasoline hydrocarbons which can seriously interfere with the measurement of methane in soil gas. In addition, methods will be demonstrated to collect gas samples by water displacement that collects samples into glass serum bottles. The approach is much less expensive than collecting samples into Summa Canisters and analyzing by GC mass spectrometry.
Petroleum Vapor - Continuous Monitoring
Sunday, March 18, 3:15 - 5:00
Typically, petroleum vapor site investigation is carried out using hand held or transportable field instruments coupled with offsite lab analyses. When using field instruments, the data generated represents a snapshot in time and space. More sophisticated field equipment such as GC/MS can provide speciation, but still suffer from poor spatial and temporal resolution.
As an alternative, investigators can choose methods such as Summa canisters that sample for a fixed period, say 24 hours, followed by lab analysis. The data generated provides speciation and the concentrations represent an average for the sampling period.
This workshop includes descriptions of instrumentation used for collecting real time continuous data for multiple parameters such as VOCs, methane, oxygen, carbon dioxide, hydrogen sulfide and carbon monoxide together with atmospheric pressure, as well as speciation of the VOC components.
A comparison between spot sampling and continuous monitoring will highlight the questions about the value of limited spot sampling.
Tribal Corrective Action Training
Sunday, March 18, 3:15 - 5:00
This workshop will be an introduction to Corrective Action at Leaking Underground Storage Tank(LUST) Sites on Tribal land. The workshop will include an overview of the federal UST Regulations for Release Reporting, Investigation, and Confirmation; as well as Release Response and Corrective Action for UST Systems. An example case study walking through the entire corrective action process, starting from suspected to confirmed release, assessment, remediation and cleanup completion will be presented. The workshop will also provide a brief overview of typical remediation technologies used at LUST sites. This workshop is designed for tribal staff who don't have corrective experience but will also serve as an excellent refresher for experienced tribal professionals.
