So far la its history the Ccaaslsslon ban adopted four Regulations, together vitb appropriate Gulden for Compliance vitb Regulations. Scoe of the previously adopted Regulations is specific for i any air pollutant and the proposed standard for lead vould be la the first batch of specific sir quality standards.

Mr. Susaaan asked that John CInland, Chief, Abatement Compliance Section and Ban Brodovics, Jr., Chief, Technical Service* Section, alt In on our dlecuctloo. Z reported to theta gentlemen that va had anticipated tha need for air quality ttandarde, had discussed .thla vith tha United States Public Health Service and tha State of California' Department of Public Health (vhlch haa a nandate to set auch standard*) and had all agreed that core Information la needed before logical and reasonable standards can ha sat. Shat about four years ago ve had ashed Kettering laboratory to conduct for us human exposure studies Involving lov level amounts of lead In specially designed chscbere, vhlch studies vould he 'vy&.- relevant to the health of the general public. The state people appeared to he Impressed vith the details of our studies and the scientific approach that our Industry Is talcing throu^i research. Z then asiced upon chat basis the 10 mlcrogrem figure had been derived, sad vaa told that It vaa about l/20th of the Industrial hygiene threshold Value of 200 nlcrogracs per cubic meter of air. Ve then had a technical discussion concerning the fallacy of such an approach to acblent air quality standards, and Mr. Susacan pointed out to me that ve should really he pleased that they had only tales l/20th of th# Industrial hygiene limit, since In the esse of beryllium they had used l/100th of the Industrial hygiene limit. Hr. Susacan further pointed cut to me that in hi* opinion th# Three Cities Survey has hewn that average aaoats of lead In air do not crcesi 3 aierograns per cubic meter and therefore ve had nothing to complain about. When Z pointed out to him that In ay opinion the 10 microgran value would he difficult for 00* of our lead plant# to meet, he told ce of a secondary smelter In Penn* ylvanla at vhlch 2* hour sample* had been tax*a by the Division and that th* highest value obtained had been 5 mlcrograas per cubic meter. \ Za scenery, ve had a very Interesting dlseussloo and the state sir pollution people vere very Interested in our research projects, hut did sot agree that their action la setting a standard at the present time It premature. It teens to me that ve nust take all necessary steps to sake certain that our voice Is heard before the next meeting of the Air Pollution Cosmieeloo. These ceetlngs are held at the call of the Chairman, and the next one has not been scheduled as yet. At the end of this report Z list for you the names of the meabers of this Commission. ' t. Z think ve are faced vith a rather serious situation, a situation that is sore serious In its Implications for the future than It Is right nov, because, ss you know, as s o o q as one govert.-ant agency takes an action of this kind ve vUl have cany others vantlng to do the sane. X have no concrete sug gest lens for action to offer to you at this time, but I think it behooves all of us to make an attempt to accumulate as much factual data as la pos* sib Is about the air outside of our o*m plants.
