One consequence is that cell repair mechanisms might be inhibited, which could lead to malignant changes (21. 22).

The potential for panic and overreaction is tremendous--leading to wasted resources and possibly higher asbestos exposures if complete removal is un dertaken in schools where modest containment measures are ap propriate.

On breaking the latter down into indi vidual causes the excess can be shown to be due to deaths from acute myocardial infarction (ICD No 410, 8th revision).8 Mortality from malignant neoplasms is given by site in table 3 for the leading causes of death from cancer in women.

C10172 19 # * i -2- Tom Hendrick: Only seven cases were chosen for the first trial in a test of legal and factual issues which could lead to similar law suits across the nation.

Environmental Quality - Non-Divisional Superfund Sites - Number of sites Dow currently active in stands at nineteen - The Kalkaska, Michigan site (old Dowell facility), currently treating recovered groundwater via Aqua Detox (Air Stripper designed by Dow and available for licensing) at a cost of $ 10,000.00 per month, has cost approximately $ 750,000.00 to date ------ Estimates show that only about 500 gallons of solvent from incidental losses to have been the original source of contamination - A unique soil gas sampling technique was employed at the Cliffs - Dow site in upper Michigan to ascertain the areal extent of contamination, primarily associated with wood tar residues ------ the sampling technique involved the shallow im plantation of activated charcoal coated wires to adsorb indi cator gases, later desorbed and identified via a gas chromatigraph Larry Bone - Dow's assigned representative to the Petro Processor Inc. site ------ an active Superfund site in Louisiana - About two and a half years and $ 5 MM dollars have been spent to date on remedial action planning; actual implementation of the remedial action is expected to take three years and cost an ad ditional $ 50 MM dollars - Have experienced "problems" with peroxide forming wastes - Initial recovery well recharge data indicates a ten year period may be needed to remove the subsurface organic solvents - Using ejector type pumps activated by timers - l.l casing volumes removed every eight hours - Recovered organics will probably be incinerated at Dow's Louisiana Division facilities - Negotiations with the governmental agencies on groundwater monitoring requirements have allowed the reduction of parameters to be analysed for ------ "harbinger" (lead, forerunner) compounds versus "indicator" compounds, will be looked for Note: Indicator parameter monitoring is not normally considered acceptable by the regulating agencies for groundwater monitoring at Superfund sites Special Guests - Non-Dow John Guswa and Charlie Faust of Geo Trans led a discussion on the characteristics of dense Non-Aqueous Phase Liquids (NAPLs) in the subsurface environment ------ methods to estimate residual soil sat uration levels, recovery well design and operation, and vertical hydraulic gradient reversal as a means to deter downward migration of dense organics were some topics of interest covered DOW CONFIDENTIAL DO 074530 OONFIDFNTIAl D.

It should also be emphasized, he said, that an association between patterns of cancer and some environment or other factor does not prove causation* "Whether changing characteristics of the United States population such as in diet, occupation, and residence, are leading to increasing or decreasing rates of cancer ean be evaluated only through epidemiologic studies that collect information on Individuals."

To require all shift supervisors and chief leads to explain pre paration procedures for all jobs.

The seminar leader has asked a number of equipment vendors and manufacturers representatives to supply "demonstrator" equipment on the justification that each seminar participant may represent a potential customei--or at least a quali fied lead.

Lengthy lead times are involved.

The committee discussed what additional comments may be appropriate should such a letter be sent (a statement of who the Vinyl Institute Is; a review of the meeting with Formosa representatives; history of industry compliance with current standard; industry's role In providing information leading to the publication of the new proposed standard; an explanation that the proposed rule is not a "reformat" of the existing standard; a review of EPA's study of gasholders and the safety problems associated with them) and whether VI member companies could expect to benefit from such a letter.

The task group's draft suggestions to OSHA on targeting inspections -- as well as the thrust of the intended ap proach on conveyors, laboratory safety and the lead standard (respiratory protection) -- were also approved by the Com mittee. 8.2 Worker Education - The task group is developing a questionnaTre to determine the extent of member need for infor mation on worker education and also to learn about current practices in this field.
