Dear Vinyl Chloride Research Coordinators:
A calendar to determine your availability to attend the next VCRC meeting is enclosed. A tentative agenda for the meeting also is enclosed.
Dr. Greg Bond anticipates sending me the draft scope of work for the epidemiology study by*^gpJ00 I will send you the draft as soon as I receive it.
Two activities recently have been initiated by EPA and ATSDR. Dr. James Knaak informs me that EPA has commissioned Clemment Associates to undertake a risk assessment for vinyl chloride. Dr. Richard Reitz, formerly of Dow Chemical, has developed a physiologically-based pharmacokinetic model for predicting cancer risk from vinyl chloride exposure. An abstract of his model is enclosed. Dr. Knaak has expressed an interest in inviting Dr. Reitz to discuss his model with the VCRC at its next meeting. As EPA's risk assessment activities for vinyl chloride already are underway, I think we should meet with Dr. Reitz as soon as possible and develop a strategy to work with EPA from the beginning to ensure a scientifically sound risk assessment.
On March 10, the ATSDR announced various research activities that are underway or are planned for vinyl chloride and other chemicals. The enclosed Federal Register notice describes those research activities. The ATSDR has three different options to develop research data as described in the background section of the Federal Register notice. The VCRC commissioned Can-Tox to review the ATSDR profile for vinyl chloride last year and a final report from Can-Tox was issued early this year.- ~ This report has not been submitted to ATSDR. I will contact Dr. William Cibulas of ATSDR to discuss various research programs underway or planned as described in Tables 1 and 2 of the Federal Register notice. It is important for the vinyl chloride industry to meet with ATSDR and/or EPA to discuss the ATSDR data needs because the ultimate cost of the ATSDR data needs on the industry will be well over $500,000, if th data needs are not minimized. One way or the other, industry ultimately will have to pay for all test costs. We will discuss the enclosed Federal Register notice at our next meeting and decide on a course of action.
Please complete your meeting availability calendar and send it to me by fax at 202/887-1237. If you have any questions, please call me at (202) 887-1192.
Sincerely,
R&S 150632

Currently, 26 priority data needs associated with 11ATSDR substances have been recommended by CPA to be added to its Master TestingList, the first step in test rule development under TSCA. section 4 (Table 2). Please note that although ATSDR has identified priority data needs for oral exposure to tetrachloroethylene, cyanide, and beryllium, in response to other Federal government agency needs, ATSDR will consider proposals to conduct Inhalation studies in conjunction with pharmacokinetic studies for these substances in lieu of bioassays using oral exposures. It is anticipated that inhalation data derived from these studies can be used, in conjunction with pharmacokinetic modeling, to address ATSDR's oral toxicity data needs.
Some of ATSDR'* priority hazardous substances will not be added to EPA'a Master Testing list because they do not fall within the bounds ofTSCA, Section 4 authority. For example. TSCA does not require testing chemicals that are out of production, such as PCBs. Furthermore, TSCA is not considered the appropriate mechanism fortesting PAHs, because the PAHs tie by products of multiple industrial processes and. therefore, it is difficult to identify specific manufacturers. In addition, TSCA guidelines are not available for some of the ATSDR priority data needs such as the development of analytical methods for cadmium and beryllium, mechanistic studies on the neurotoxic effects of lead, and the mitigation of toxicity ofvinyl chloride. Moreover, some of the ATSDR priority hazardous substances are considered more appropriate for FIFRA than TSCA, e.g., arsenic, DDT, and aldrin/dieldrin. The Office of Pollution, Prevention and Toxics (OPPT), EPA,
forwarded the data needs for these substances to the Office ofPesticide
Programs for evaluation.
B. Private Sector Voluntarism
As part of the SSARP, ATSDR initially announced a set of proposed
, procedures for conducting voluntary research on February 7,1992 (58 FR 14758). It was revised based on public
comments and published on November 16,1992 (57 FR 54160). This voluntary z research program fills priority data needs along with other mechanisms - such as test rule development through EPA and CERCLA-funded research. Private sector organizations were
encouraged to volunteer to conduct . research to fill these specific priority
data needs.

establishing registries and surveillance cohorts in the Great Lakes region; and (5) establishing a chemical mixtures database with emphasis on tissue and blood levels in order to identify new cohorts, conduct surveillance and health effects studies, end establish registries and surveillance cohorts.
During FY1992, ATSDR announced a 52 million grant program to conduct research on the impact on human health of contaminated fish consumption in the Great Lakes region. On September 30,1992, ATSDR announced nine awIanrFdsYu1n9d9e3r, tahbisonurtosRfrmamili.ian was

priority data need far 37 of the 38 priority substances (Table 1). ATSDR will obtain this inhumation through
exposure and health effects studies, and through establishing and using substance-specific subregistries of people within the Agency's National Exposure Registry who have potentially
been exposed to these substances. The list of 38 priority hazardous
substances in the SSARP was forwarded to ATSDR's Exposure and Disease Registry Branch (EDRB), Division of Health Studies, for consideration as
potential candidates for suhreglstries of exposed persons, based an criteria described in EDRB*s 1988 document, "Policies and Procedures for Establishing a National Registry of Persons Exposed to Hazardous Substances." To date, ATSDR has elected benzene, chromium, and trichloroethylene as primary contaminants to establish subregistries in the National Exposure Registry. However, aldrin/dialdrin, carbon tetrachloride, chlaroethane. chloroform, cyanide, p,p'-DBT, DDE.DDD, di (2ethylhexyl) nhthalate, mercury, methylene chloride, PAHa, selenium, tetrachloroethylane, and vinyl chloride remain aa a part of the candidate pooL They will be considered for selection as pjrwiy HintMitniBh Airing rii

Finally, arsenic, beryllium, cadmium, lead, nickel PCBs, toluene, and zinc are not considered to be In the pool of candidate substances for an exposure registry at this time. This decision will be re-evaluated as mare information on the chemicals and exposure sites become available.
With regard to epidemiologic studies, ATSDR believes that for many of the 38 priority hazardous substances, an extensive amount of animal data, and some human data, have already been collected; therefore, ATSDR considers It appropriate, where feasible, to conduct
epidemiologic studies on such substances. In response to public comments, the Agency's SSARP will address substance-specific rather than site-specific epidemiologicstudies.
The substance-specific studies are designed to determine substancespecific cause and effect. In this case, ATSDR is not necessarily directed
toward populations exposed via the environment at hazardous substance release sites, aa in a site-specific study.
Instead, any appropriate population of suitable exposure via the environment.
consumer products, or occupation can be used to design a rigorous analytic epidemiologic investigation. Epidemiologic studies on several of ATSDR's 38 priority hazardous substances (such aa DDT, PCBs, and PAHs) are being conducted by the ATSDR (heat Lakes human health effects research program (Table 5).
Two epidemiologic studies on lead (identified as a data need by ATSDR), are also being conducted by the Morehouse School of Medicine and the King/Drew Medical Center of the Charles R. Drew University ofMedfdne and Science via the ATSDR~-MHPF cooperative agreement ATSDR expects
that otheraubstance-apedfic epidemiologic studies, identified as data needs or priority data needs in the SSARP, may potentially be conducted by other Divisions witltin ATSDR.
ATSDR acknowledges that the conduct of epidemiologic studies to determine possible linkages between exposure to hazardous substances and human health effects may be accomplished other than by Agency programs, or under other ATSDR- . sponsored auspices. Toward that end, thg Agency encourages the private sector and other government programs to use ATSDR's priority data needs to plan research activities to identify appropriate populations and conduct studies addressing the specific human
health issues.
Finally, the collection, evaluation, and interpretation of data from contaminated media around hazardous waste sites have hear identified aa priority data needs for all 38 priority hazardous substances by ATSDR. However, the Agency realizes that a lot of information has already been collected through-individual state programs and the EPA's CERCLA activities; therefore, ATSDR will . evaluate the extant information from
these programs in order to help fill data needs on substance-specific exposures.
The results of the research conducted via the SSARP will be used fin public health assessments and to reassess ATSDR's substance-specific priority data needs. The Agency expects to re evaluate the priority data needs for priority hazardous substances every three years.
