Description:
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 U.S. 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 contamination due to metals.
The research goal 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 that 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 and service to communities (TOSC), and technical assistance for 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 and 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 U.S. Geological Survey who are involved in mine waste research, and 14 researchers 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.

Director's Report
November 1, 2002–October 31, 2003 represents the second year of Center activity. The Rocky Mountain Regional HSRC is an extension of the previous HSRC located at Kansas State University that represented U.S. EPA Regions 7 and 8. With the advent of the five new HSRCs in November 2001, U.S. EPA Region 7 now is associated with the Midwest HSRC located at Purdue University, West Lafayette, IN, and U.S. 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 U.S. EPA Region, whereas the other four HSRCs represent either two or three U.S. EPA Regions. Although this distinction allows the Rocky Mountain Regional HSRC to focus on the primary environmental issues of U.S. EPA Region 8 (environmental impacts resulting from mining activities and abandoned mine lands), the allocation of funds in proportion to U.S. 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 six research projects during the second year. The first four projects (Projects 1-4) were initiated the in first year and continued through the second year. Each of these projects was a 2-year project and, therefore, terminated at the end of the second year (i.e., October 31, 2003). In addition to these four projects, two new projects (Projects 5 and 6) were funded beginning the second year (i.e., November 1, 2002) in response to the call for proposals released on April 9, 2002. The scheduled termination of Projects 1-4 freed up funding for new projects that would start in the third year (i.e., November 1, 2003). As a result, a request for proposals for the 2003-2004 funding cycle was released on February 10, 2003, and 15 proposals were received by the deadline of March 31, 2003. These proposals were sent to the SAC for review prior to the Center’s second meeting on May 19-20, 2003, and were evaluated and ranked by the SAC members on May 20, 2003. Based on the ranking of the proposals, and the available budget, five new projects are being funded during the third year. Therefore, a total of seven research projects will be funded during the third year of the Center (see Table 4).
Highlights of Year 2 of the Project
In addition to the research and outreach activities conducted through the Rocky Mountain Regional HSRC, the second-year activities of the Center involved significant efforts to increase the exposure to and networking with as many of the stakeholders as possible. For example, oral presentations about the Center were given by the Center Director at two major mining conferences: (1) the Joint Conference of the 9th Billings Land Reclamation Symposium and the 20th Annual Meeting of the American Society of Mining and Reclamation, Billings, MT, June 3-6, 2003; and (2) the Workshop on Mining Impacted Native American Lands, Reno, NV, September 9-11, 2003.
Other Center personnel made presentations on behalf of the Center, including Dr. Craig Benson (Project 5 Co-Principal Investigator [Co-PI]) at the Mine, Design, Operations and Closure Conference held in Polson, MT, on April 27-30, 2003; and Dr. Linda Figueroa (Project 3 Principal Investigator [PI]) at the Green Brownfields II Conference held in Dresden, Germany, on June 14-19, 2003. Finally, both the 2003 Mine Design, Operations and Closure Conference and the Tailings and Mine Waste 2003 Conference were co-sponsored by the Rocky Mountain Regional HSRC. For the first time in its 10-year history, the Tailings and Mine Waste Conference was held outside the campus of Colorado State University in Vail, CO, on October 12-15, and was such a rousing success that plans already are underway to hold the conference next year at the same time of the year and at the same location and venue.
The Center Director, Charles Shackelford, also participated in the annual HSRC Director's meeting held on August 26-27, 2003, in Cincinnati, OH. Two presentations on Center research were given at this meeting. First, Charles Shackelford, Co-PI of Center Project 5, gave an overview of the research to be conducted on this project. Second, Dr. Pierre Julien, PI of Center Project 2, presented the results of the first approximately 1.5 years of effort on his Center-sponsored research project.
Another highlight of 2003 was the Center’s second annual meeting held on May 19-20 at the Colorado School of Mines, with Center Associate Director Don Macalady serving as organizer and host for the meeting. This meeting is one of the two semi-annual meetings required by the U.S. EPA for the Center, and 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 six PIs for the second-year research projects, as well as a presentation by Karl Burgher, Director of TAB and TOSC, on the 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 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 May 20, 2003. The outcome of this evaluation by the SAC was that all projects were making satisfactory progress. In addition, the SAC also evaluated 15 proposals submitted in response to a Request For Proposal, and recommended that 5 of these 15 proposals be funded beginning the third year.
In addition to the semi-annual Center meetings required by the U.S. EPA, the Rocky Mountain Regional HSRC also organizes internal Center meetings that rotate among Colorado State University, Colorado School of Mines, and U.S. EPA Region 8 Headquarters in Denver. The purpose of these internal meetings is to maintain communication among all interested parties. The meetings generally last about 90 minutes and consist of about 30 minutes for Center news and announcements, followed by a 1-hour seminar given by a PI of one of the funded research projects. For the second year of Center activities, the only internal meeting was held at Colorado State University on March 19, 2003. This meeting included a seminar by Dr. Linda Figueroa, PI for Project 3 of the Center. Only one internal meeting was held during the second year of Center activities because one meeting was conducted late in the first year (i.e., November 8, 2002), and another internal meeting is scheduled for early in the third year (i.e., December 10, 2003). These meetings will be continued throughout the duration of the Rocky Mountain Regional HSRC at a frequency of about one to three per year.
A list of the research projects at the Rocky Mountain Regional HSRC for the second year of Center activity is provided in Table 5. There are separate reports that describe the progress for each of these research projects. However, the entire list of publications for the Center is presented in this report rather than in the separate project reports.
