Also present was Alina Martin of Science Applications International Corporation.
SUMMARY OF PREVIOUS CALL
In the first conference call, the group discussed the idea of a new partnership between EPA, the oil industry and several other federal agencies. One reason EPA is pursuing this partnership is to tackle NAPL management on the large scale and to address what technologies are available for aggressive NAPL removal. EPA is interested in the cost and performance of these technologies and how more information can be dispersed. Also, EPA would like to address the question of how to evaluate the costs and benefits of these innovative technologies over traditional methods, such as pump and treat.
The partnership will give the group the opportunity to leverage resources and to take advantage of collaborative efforts to answer these questions.
The four EPA offices that would be involved in this effort would be the Technology Innovation Office, EPA Region 8, the SITE Program, and the Office of Research and Development.
Potential topics for the group were discussed:
Defense Energy Support Center - Paul Rogers
DESC is part of the Defense Logistics Agency. It buys, stores, and distributes all of the petroleum products for military services around the world, making it the single largest buyer of petroleum products in the world. It operates several bulk storage fuel terminals throughout the US and Korea. It funds compliance and cleanup at all of the military bulk storage facilities at military bases throughout the world (about 400 sites).
DESC has not been too involved in innovative technologies, but has looked at some of the following: steam injection systems, barrier walls, slurry trenches, and phytoremediation. Most of the focus has been placed on prevention rather than cleanup, however DESC is very interested in participating in this group.
Equiva Services - David Zabcik
Equiva is a service entity between Equilon and Motiva. It focuses on refineries, terminals, pipelines, and retail locations. It has a wide range of systems installed for remedial operations. Depending on location, it has a full range of focuses, including the following: perimeter control systems, source control, and remediation of broad areas. Equiva has used a variety of technologies ranging from phytoremediation to pump and treat. One interest of Equiva is to look at appropriate endpoints.
Lyondell Chemical - Dick Sloan
Lyondell used to be the petrochemical division of Arco. It spun off a couple of years ago. Lyondell has two broad areas that it is currently involved in:
Lyondell has approximately 40 remediation projects worldwide, all in different stages of remediation. The company usually uses a sequenced approach, involving the following steps:
Lyondell is currently using a full list of technologies, including the following: in situ bioremediation, soil vapor extraction, thermal desorption, and thermal oxidation.
Lyondell has found that every site is unique and a specific approach is needed for each site. The most timely cost-effective approach is to do a good job of defining the physical conditions and the chemical conditions up front. The company usually creates the designs, plans, and strategic approaches in-house and uses contractors to implement the approaches.
Lyondell is extremely active in terms of sites and is very interested in the partnership approach and in sharing information.
Conoco Inc. - Terry Lauck
Greg Fletcher is the Remediation Program Manager for the Conoco Denver refinery. Conoco has done a lot of research with a number of universities and used to do a lot of work through Dupont. The central remediation group is in the Houston office.
The Denver refinery is about 280 acres. Refining activities date back to the 1930s. It was the nation's first continuous processing refinery back in 1931. The Conoco refinery processes about 60,000 barrels per day.
The current remediation project is a joint effort with the Colorado Refining Company. Any effort that Conoco would get involved with would also involve working with the Colorado Refining Company.
The main concern of the site is NAPLs seeping into the creek. The long-term plan is product recovery using dual-phase recovery with some water flooding to reduce the mobility of the pre-phase hydrocarbons to the maximum extent practicable.
Conoco is going to have some boundary control using physical and/or hydraulic barriers. The main focus right now is physical containment along the creek.
PARTNERSHIP KICKOFF MEETING
The partnership kickoff meeting will most likely take place in May 2000. SAIC will send out a calendar and participants can check off the dates on which they are not available. By scheduling the meeting in the near future, the group hopes to keep momentum and interest in the project.
The meeting will be 1 ½ - 2 days long. The first day will focus on more brainstorming and discussing the scope and purpose of the group. There will probably be several presentations. On Day 2, the group may wish to make a site visit to an oil refinery.
One potential location for the site visit is at the Ashland Refinery in St. Paul, Minnesota. It is an operating refinery that is applying the microwave technology for NAPL removal. The group discussed how the site might not have geology characteristics that are relevant to most organizations. In addition, the group discussed the conflict between focusing on operating or closed refineries.
One attendee suggested sending out a list of possible locations with descriptions of the technologies used. Kathy Yager will come up with a list of potential sites and members of the group will be asked for input on their top choices. Please send any location suggestions to Kathy Yager.
Another possible site may be Cape Canaveral where they are looking at two thermal technologies and oxidation. However, this site is very small-scale.
Ali Tavelli suggested going to a site where there is an existing partnership between EPA and industry. It would provide a concrete example to the group on how a partnership works.
At the meeting, the group would like to give organizations the opportunity to highlight strategies and primary issues they face. Technical as well as financial issues should be addressed. It was suggested that two or three presentations be made. Volunteers interested in presenting should contact Kathy Yager.
Kathy Yager posed the question of whether the group should spend time discussing a legal agreement. The group felt that since this meeting is more of a scoping effort, it does not seem necessary at this time.
Randy Breeden and Kathy Yager will put together a preliminary agenda for the meeting and will send it out to the group for comment.
Kathy Yager emphasized that the partnership meeting is open and that anyone may attend.
