ASTSWMO is pleased to invite State and Territorial (State) Leaking Underground Storage Tank (LUST) managers, U.S. EPA Headquarters and Regional staff, and other guests to the 2019 ASTSWMO LUST Workshop in New Orleans, LA. The two-and-a-half-day Workshop will provide a forum for information sharing and interaction among all participants, training, and national and State policy updates for attendees. Priority attendance will be given to our members, federal officials, and invited guests due to limitations on hotel meeting space capacity and accommodations availability. Additional information on State member reimbursement and participation for this year’s Workshop is provided in the full announcement.

The theme of this year’s Workshop is “Sharing Solutions to Advance LUST Cleanups.” Sessions will identify challenges that State programs encounter in closing LUST sites and offer possible solutions to advancing cleanups. The Workshop has been organized to promote interaction among States, the U.S. EPA, and other attendees, and each session will include opportunities for dialogue and information sharing on the session topic.
Presentations
Welcome and introductions from ASTSWMO, the Louisiana Department of Environmental Quality and the U.S.
EPA Office of Underground Storage Tanks.
Money makes the world go around and it often is the critical factor in accomplishing LUST cleanups. While U.S. EPA cooperative agreements and State Funds have helped States fund site cleanups throughout the years, States have had to create new funding sources to accomplish additional cleanups. Representatives from California and Washington will present details on their creative funding successes. All States will be able to share their creative solutions in an open discussion.

This session will discuss how to get from high resolution site characterization to remediation, how to use
treatment trains, and some of the unexpected results that can come from remediating a site.

Implementation of RBCA to achieve LUST Case Closure has gained more acceptance in many States. There are many sites where case closure cannot be achieved due to the stringent targets and numbers. However, these sites can be evaluated from the risk point of view considering current and future receptors/scenarios using the applicable exposure pathways. This session will focus on the application of RBCA and how it is accelerating case closures. Three States are going to share their experiences that could help others in achieving closures in their States.

Presentation 3
Exploring options to deal with difficult residual contaminant mass after significant effort and resources have been expended and a site displays asymptotic conditions. This session will examine the California low-threat UST case closure policy, the Montana petroleum mixing zone (PMZ) closure policy and look at South Carolina’s pilot study pertaining to the optimization of their RBCA.

States across the nation have struggled with closing old, legacy sites that have lingered for years due to various reasons. This session will cover how States have re-assessed old, stalled cases and their strategies to address them. The speakers will begin the conversation on what their States have done, followed by a group discussion to continue the strategy sharing.

Every State has orphan underground storage tank sites creating environmental issues, hindering development, adding to a State’s backlog of sites to address or are just plain eyesores to the local community. This session will provide examples from a few States on how they are addressing their orphan tank sites and may just provide the information you are seeking to begin a similar type program in your State. There will be plenty of time to ask questions of the presenters or provide feedback on how your State addresses these types of sites.

Presentation 2
How are States using MNA? Are any States closing LUST sites with MNA? How do you determine plume stability? Speakers will share experiences followed by discussion among the States.

Coordinating, communicating, and effectively working with consultants is a critical component of any successful remediation, and may make the difference between a successful remedial action and a site that lingers for years. This session will be a focused discussion on the challenges regulators and consultants face when working together; impacts of new regulations on consultants; development of ideas or practices that benefit both consultants and regulators that ultimately result in more effective or faster remediation; as well as sharing “lessons learned” from both regulators and consultants that led to more effective remediation.
Presentation
Challenges are prevalent in addressing contamination that has migrated offsite. Strategies to coordinate with offsite property owners and developers, addressing offsite NAPL, and applying institutional controls will be presented in this session.
