Agency for Toxic Substances and Disease Registry (ATSDR), U.S. Department of Health and Human Services (HHS).
This notice announces the final priority data needs for two priority hazardous substances (see Table 1) as part of the continuing development and implementation of the ATSDR Substance-Specific Applied Research Program (SSARP). The notice also serves as a continuous call for voluntary research proposals.
The exposure and toxicity priority data needs in this notice were distilled from the data needs identified in ATSDR's toxicological profiles by the logical scientific approach described in a decision guide published in the Federal Register on September 11, 1989 (54 FR 37618). The priority data needs represent essential information to improve the database for conducting public health assessments. Research to address these priority data needs will help to determine the types or levels of exposure that may present significant risks of adverse health effects in people exposed to the hazardous substances.
The priority data needs announced in this notice reflect the opinion of ATSDR, in consultation with other federal programs, about the research needed pursuant to ATSDR's authority under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 Start Printed Page 901(Superfund), or CERCLA, as amended by the Superfund Amendments and Reauthorization Act of 1986 (SARA) [42 U.S.C. 9604(i)]. The needs identified here do not represent the priority data needs for any other agency or program.
Consistent with section 104(i)(12) of CERCLA as amended [42 U.S.C. 9604(i)(12)], nothing in this research program shall be construed to delay or otherwise affect or impair the President, the Administrator of ATSDR, or the Administrator of the Environmental Protection Agency (EPA) from exercising any authority regarding any other provision of law, including the Toxic Substances Control Act of 1976 (TSCA), the Federal Insecticide, Fungicide, and Rodenticide Act of 1972 (FIFRA), or the response and abatement authorities of CERCLA.
ATSDR worked with other federal programs to determine common substance-specific data needs and mechanisms to implement research that may include authorities under TSCA and FIFRA, private-sector voluntarism, or the direct use of CERCLA funds.
Table 1 presents the priority data needs for acrolein and barium, two priority substances included in the ATSDR Priority List of Hazardous Substances (73 FR 12178, March 6, 2008). These priority data needs were initially announced by ATSDR in the Federal Register on September 8, 2006 (71 FR 53102). The public was invited to comment on these data needs for these two substances during a 90-day period. No public comments were received. These priority data needs and accompanying documents were reviewed by EPA and the National Institute of Environmental Health Sciences (NIEHS), and will be addressed by the mechanisms described in the “Implementation of Substance-Specific Applied Research Program” section of this Federal Register Notice.
|Substance||Priority data needs|
|Acrolein||Exposure levels in humans living near hazardous waste sites and other populations.|
|Exposure levels in children.|
|Dose-response data for chronic duration 1 via inhalation exposure.|
|Barium||Dose-response data for acute duration 2 via oral exposure.|
|1 365 days or more.|
|2 14 days or less.|
The substance-specific priority data needs were based on and determined from information in corresponding ATSDR toxicological profiles. Background technical information and justification for the priority data needs in this notice are in the priority data needs documents, available on ATSDR's Web site at http://www.atsdr.cdc.gov/pdns/. Printed copies are also available by written request from ATSDR (see ADDRESSES section of this notice).
Voluntary Research. This notice also serves as a continuous call for voluntary research proposals. Private-sector organizations may volunteer to conduct research to address specific priority data needs in this notice by submitting a letter of intent to ATSDR (see ADDRESSES section of this notice). A Tri-Agency Superfund Applied Research Committee (TASARC), comprised of scientists from ATSDR, the National Toxicology Program (NTP), and EPA will review all proposals.
The ATSDR voluntary research program is a continuous program, and private-sector organizations can volunteer to fill identified data needs from now until ATSDR announces that other research has been initiated for a specific data need.
The priority data needs are available on ATSDR's Web site at http://www.atsdr.cdc.gov/pdns/. Private-sector organizations interested in volunteering to conduct research to fill identified priority data needs should write to Nickolette Roney, Applied Toxicology Branch, Division of Toxicology and Environmental Medicine, ATSDR, 1600 Clifton Road, NE., Mailstop F-32, Atlanta, Georgia 30333; e-mail: NRoney@cdc.gov. Information about pertinent ongoing or completed research that may fill priority data needs cited in this notice should be similarly addressed. Also, use the same address to request printed copies of the priority data needs documents.Start Further Info

CERCLA, as amended by SARA [42 U.S.C. 9604(i)], requires that ATSDR (1) develop jointly with EPA a list of hazardous substances found at National Priorities List (NPL) sites (in order of priority), (2) prepare toxicological profiles of these substances, and (3) ensure the initiation of a research program to address identified priority data needs associated with the substances.
The SSARP was initiated in 1991. A list of priority data needs for 38 priority hazardous substances was announced for public comment in the Federal Register on October 17, 1991 (56 FR 52178) and was published in final form on November 16, 1992 (57 FR 54150). In 1997, after releasing for public comment, ATSDR finalized the priority data needs for a second list of 12 substances and that priority data needs list was announced in the Federal Register on July 30, 1997 (62 FR 40820). ATSDR then identified priority data needs for a third list of 10 hazardous substances; this list was released as a draft for public comment and published in its final form on April 29, 2003 (68 FR 22704). On September 8, 2006 (71 FR 53102), ATSDR released for public comment the priority data needs for the two hazardous substances that are the subject of this final notice.
The ATSDR SSARP supplies the necessary information to improve the database to conduct public health assessments. The link between research and public health assessments and the process for distilling priority data needs from the data needs identified in associated ATSDR toxicological profiles are described in the ATSDR “Decision Guide for Identifying Substance-Specific Data Needs Related to Toxicological Profiles” (54 FR 37618, September 11, 1989).
Implementation of Substance-Specific Applied Research Program
In Section 104(i)(5)(D), CERCLA states that Congress believes the costs for conducting this research program should be borne by the manufacturers and processors of the hazardous substances found under the Toxic Substances Control Act of 1976 (TSCA); by registrants under the Federal Insecticide, Fungicide, and Rodenticide Act of 1972 (FIFRA); or by cost recovery from responsible parties under CERCLA. To execute this statutory intent, ATSDR developed a plan whereby parts of SSARP are being conducted through regulatory mechanisms (TSCA/FIFRA), private-sector voluntarism, and the direct use of CERCLA funds.
CERCLA also requires that ATSDR consider recommendations of the Interagency Testing Committee, established under section 4(e) of TSCA, for the types of research to be done. ATSDR actively participates on this committee. Federally funded projects that collect information from 10 or more respondents and that are funded by Start Printed Page 902cooperative agreements are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act. If the proposed project involves research on human subjects, the applicants must comply with Department of Health and Human Services regulations (45 CFR part 46) regarding the protection of human subjects. The applicants must ensure that the project will be subject to initial and continuing review by the appropriate institutional review committees. Overall, by providing additional scientific information for the risk assessment process, data generated from this research will support other researchers who are conducting human health assessments involving these two substances.
The mechanisms for implementing SSARP are discussed next. The status of SSARP in addressing priority data needs of the first 60 priority hazardous substances through these mechanisms was described in a Federal Register Notice on December 13, 2005 (70 FR 73749).
In developing and implementing SSARP, ATSDR and EPA established procedures to identify priority data needs of common interest to multiple federal programs. Where practicable, these data needs will be addressed through a program of toxicologic testing under TSCA or FIFRA. This part of the research will be conducted according to established TSCA/FIFRA procedures and guidelines.
B. Private-Sector Voluntarism
As part of SSARP, on February 7, 1992, ATSDR announced a set of proposed procedures for conducting voluntary research (57 FR 4758). Revisions based on public comments were published on November 16, 1992 (57 FR 54160). ATSDR strongly encourages private-sector organizations to propose research to address priority data needs at any time until ATSDR announces that research has already been initiated for a specific priority data need. Private-sector organizations may volunteer to conduct research to address specific priority data needs identified in this notice by submitting a letter of intent.
The letter of intent should be a brief statement (1-2 pages) that identifies the priority data need(s) to be filled and the methods to be used. TASARC will review these proposals and recommend to ATSDR the voluntary research projects that should be pursued—and how they should be conducted—with the volunteer organizations. ATSDR will enter into only those voluntary research projects that lead to high-quality, peer-reviewed scientific work. Additional details regarding the process for voluntary research are in the Federal Register Notices cited in this section.
Those priority data needs that are not addressed by TSCA/FIFRA or initial voluntarism will be considered for funding by ATSDR through its CERCLA budget. Much of this research program is envisioned to be unique to CERCLA—for example, research on substances not regulated by other programs or research needs specific to public health assessments. A current example of the direct use of CERCLA funds is a cooperative agreement with the Association of Minority Health Professions Schools (AMHPS) that supports the AMHPS Environmental Health, Health Services, and Toxicology Research programs.
Mechanisms to address these priority data needs may include a second call for voluntarism. Again, scientific peer review of study protocols and results would occur for all research conducted under this auspice.
ATSDR encourages private-sector organizations and other governmental programs to use ATSDR's priority data needs to plan their research activities.Start Signature
