Objective:

The Rocky Mountain Regional Hazardous Substance Research Center (HSRC) consists of a consortium of Colorado State University, Colorado School of Mines, Montana Tech of the University of Montana, and several academic and nonacademic participants from other regions of the United States and Canada. The Rocky Mountain Regional HSRC was established on November 1, 2001, through funding from the U.S. Environmental Protection Agency (EPA) to address issues related to remediation of mine waste sites. The Rocky Mountain Regional HSRC officially represents EPA Region 8 states (Colorado, Montana, North Dakota, South Dakota, Utah, and Wyoming). The activities of the Rocky Mountain Regional HSRC, however, also pertain to any location within the United States, particularly where remediation of mine waste is required and/or where there is metals contamination.

The objective of the Rocky Mountain Regional HSRC is to develop new, and to improve existing, methods or technologies for remediation of mine waste sites that are cost effective and lead to cleanups that are protective of human health and the environment. The Rocky Mountain Regional HSRC also includes activities pertaining to technology transfer, Technical Outreach Services for Communities (TOSC), and Technical Assistance to Brownfields (TAB). Technology transfer includes such activities as conferences, short courses, workshops, and field demonstrations, with a specific emphasis on the development of new technologies. The TOSC and TAB Programs provide educational information to allow communities to make informed decisions concerning environmental contamination and provide technical assistance to communities and other stakeholders, including the redevelopment of brownfields sites.

Progress Summary:

The consortium member faculty and associated participants for the Rocky Mountain Regional HSRC are listed in Table 1. The consortium member faculties collectively represent an integrated research team comprised of 12 departments (biology, chemical engineering, chemistry and geochemistry, civil engineering, earth resources, environmental health, environmental science and engineering, fishery and wildlife biology, geology and geological engineering, microbiology, mining engineering, and rangeland and ecosystem science) and a much broader range of expertise areas. The associated partners for the Rocky Mountain Regional HSRC, who also are eligible to participate in research and outreach activities through the Center, consist of members from three of the other four HSRCs (Katherine Banks and Paul Schwab, Midwest HSRC; Danny Reible, South & Southwest HSRC; John Westall, Western HSRC), several other academic institutions spread throughout the United States and one in Canada (David Blowes), four researchers at the United States Geological Survey who are involved in mine waste research, and one researcher at Brookhaven National Laboratory. These other participants not only strengthen the research capabilities of the Center but also provide links through which to coordinate research activities with the other HSRCs, academic institutions, and federal agencies.

Charles Shackelford serves as the Director of the Center and the overall research program. Karl Burgher is the Associate Director in charge of training, technology transfer, and community outreach, and Donald Macalady serves as an Associate Director in charge of QA/QC for the Center and coordinating the research activities at the Colorado School of Mines. Tom Wildeman serves as a Co-Director for training and technology transfer and coordinates these activities at the Colorado School of Mines. Linda Hinshaw is employed on a half-time basis as an Administrative Assistant to the Director.

Two major advisory groups guide the activities of the Center. The Science Advisory Committee (SAC) has oversight for all Center research activities, including reviewing the progress of existing research projects, as well as reviewing and recommending proposals that have been submitted for new research projects. The Technology Transfer Advisory Committee (TTAC) oversees the Center's training and technology transfer activities as well as the outreach activities. The members of the SAC and TTAC during this past year are listed in Tables 2 and 3, respectively. As indicated in these tables, SAC and TTAC members represent the full range of stakeholders in the mine waste remediation arena, including both regional and federal EPA personnel, other federal agencies with mine waste issues (U.S. Forest Service, Bureau of Land Management, U.S. Department of the Interior), a regional state environmental agency (Montana Department of Environmental Quality), consulting companies (Knight Piesold, MFG [Shepard Miller]), MSE Technology Applications), industry (DuPont), and several academic institutions. In addition, four of the six Region 8 states (Colorado, Montana, South Dakota, and Wyoming) are represented through SAC and TTAC membership. Finally, although the Center is linked to three of the four HSRCs through other participants, linkage to the fourth HSRC, the Northeast HSRC, is provided through Kevin Hood, who serves as a member of the TTAC.

The Rocky Mountain Regional HSRC is an extension of the previous HSRC located at Kansas State University that represented EPA Regions 7 and 8. With the advent of the five new HSRCs in November 2001, however, EPA Region 7 now is associated with the Midwest HSRC located at Purdue University, and EPA Region 8 now is represented solely by the Rocky Mountain Regional HSRC. As a result, the Rocky Mountain Regional HSRC is the only current HSRC that is affiliated with only one EPA Region, whereas the other four HSRCs represent either two or three EPA Regions. Although this distinction allows the Rocky Mountain Regional HSRC to focus on the primary environmental issue of EPA Region 8, environmental impacts resulting from mining activities and abandoned mine lands, the allocation of funds in proportion to EPA Region representation has ramifications with respect to the number of activities that can be undertaken through the Rocky Mountain Regional HSRC.

The Center funded seven research projects during Year 3. Two of these projects (R829515C007 and R829515C008) represent projects that were initiated during Year 2 of Center activity and continued through Year 3 of Center activity. Project R829515C007 is a 3-year project and therefore will continue on through Year 4 of Center activity (2004-2005), whereas project R829515C008 was a 2-year project that terminated as of the end of Year 3. In addition to these two projects, five new projects (R829515C009, R829515C010, R829515C011, R829515C012, and R829515C013) were funded at the beginning of Year 3 in response to the call for proposals that was released on February 10, 2003.

Subcontracts were awarded to Montana Tech to undertake all TOSC and TAB activities for the Center. These TOSC and TAB activities are undertaken primarily through the direction of Karl Burgher, Associate Director of the Center, and his assistant, Kevin Mellott. During 2004, Karl and Kevin participated in seven TOSC and five TAB projects.

Another important objective of the Center is the education of students interested in careers directed toward finding solutions to environmental problems, particularly mine waste problems. A listing of the students associated with the 11 research projects conducted through the Center to date is given in Table 4. As shown in Table 4, Center research projects provided half-time stipends or partial (hourly) support for 13 students working toward their Ph.D. degrees, 13 students working toward their M.S. degrees, and 7 students working toward their B.S. degrees. Center research also involved three postdoctorates, five visiting scholars, and one visiting professor.

Highlights of Year 3

In addition to the research and outreach activities conducted through the Rocky Mountain Regional HSRC (see Annual Reports for R829515C005 to R829515C013), the Year 3 activities of the Center involved significant efforts to increase the exposure to and networking with as many of the stakeholders as possible. For example, an oral presentation about the Center was given by the Center Director, Charles Shackelford, for EPA's Environmental Research Seminar held at EPA Region 8 Headquarters in Denver, Colorado, on May 12, 2004. The Center Director also gave a presentation on project R829515C007 at this seminar. The Center cosponsored an exhibitor’s booth along with MSE’s (Butte, Montana) Mine Waste Technology Program at the Society for Mining, Metallurgy, and Exploration Annual Meeting held in Denver on February 22-26, 2004. Finally, the Center cosponsored for the third straight year the 2004 Mine Design, Operations & Closure Conference held on April 25-28 in Polson, Montana, and for the second straight year the Tailings and Mine Waste ’04 conference held on October 10-13 in Vail, Colorado. Although both conferences were well received and considered to be highly successful from a technical viewpoint, attendance at the Tailings and Mine Waste ’04 conference was well below expectations, primarily because of unforeseen conflicts with other conferences and workshops pertaining to the professional mining community.

The Center Director also participated in the annual HSRC Directors’ Meeting that was held on November 3, 2004, at EPA’s National Exposure Research Laboratory (NERL) in Las Vegas, Nevada. In addition to a brief overview of the Center by the Center Director to personnel at EPA’s NERL, two graduate student posters on Center projects R829515C007 and R829515C010 were displayed. This Directors’ Meeting was followed by a 2-day workshop, November 4-5, on EPA/Office of Research and Development-HSRC Superfund Research on Risk Characterization and Monitoring. At this workshop, two presentations on Center research were given. First, Ed Redente, co-principal investigator (PI) of Center project R829515C012, gave an overview of the progress of the research on this new Center project. Second, Dr. Jim Ranville, PI of Center project R829515C013, presented the results of the first half year of effort on his Center-sponsored research project.

Another highlight of 2004 was the Center’s third annual meeting held August 8-9 at Colorado State University. This meeting is one of the two semiannual meetings required by EPA for the Center, with the other meeting being the semiannual meeting with only the SAC, which was held on January 30, 2004, at the Denver International Airport. The annual meeting in August consisted of oral presentations, poster presentations, social events, and formal meetings of the SAC and TTAC. The oral presentations were moderated by the Center Director and consisted of presentations by each of the seven PIs for the Year 3 research projects, as well as a presentation by Kevin Mellott on the TOSC and TAB outreach activities being conducted on behalf of the Center at Montana Tech of the University of Montana. The audience consisted of Center administrative personnel, members and participants of the Center, SAC and TTAC members, and students who are involved in Center research. The students were required to generate posters on their research for display and presentation during lunch on the first day. The SAC then used the oral presentations, poster presentations, and progress reports generated by the PIs and distributed to SAC members prior to the meeting as a basis for evaluating the progress of the existing projects on August 10, 2004. The outcome of this evaluation by the SAC was that all projects were making satisfactory progress.
