As you are acutely aware, Sid, all of us connected with this examination process hav. been frustrated by factors essent ia i 1 v beyond our immediate con: ro 1 . Specifically, four different vendors have been contracted with .and their track records have not been exceptional. Data between these vans has not been able to be exchanged. Health Examinetics Inc. does however appear to ne capable of staying in business long enough to work with us. Ae have received in the Medical Division copies of Plant Pop ulation Summaries for 1950 and 1981 for LCCP as well as the other sites tested by HEI. (Similar copies were also provided to representatives in management for all sites). The summaries re flect the number of employees examined, daces of examination, and totals tor each test modality performed at each test site. A comparison of LCCP's p.pulation data with the rest of Conoco tested has not reflectec any health trends - either posicive or PTH 000022Z&4 Page 3 Trend Analy sis Jne ma jo r p r o b1e m that e X ! s t s is tha t a sal islactory c umparisen p o p u La t i o n does nr: t app i r e ri 11 y exist tor most plants and ?:he re b\ or oh i oi` s the dovolopmt n t o t a re a 1 1 y wort hwh i 1 e :eudv.

Unfortunately, tae development of such a system of this magnitudtakes several months to years. During the interim, we can depend 'n tar current sources t> provide allof us with data to review and work with. 'hi Have any epidemiological studies been made which would show what the most appropriate screening test indicators are? Except for the standard liver profile battery of tests for VCM exposure, no specific screening tests, per se, have been developed tor general industry l ype exposures. Certainly a pulmonary function test and chest x-rays pLace specific roles in dusty environments and blood lead results where required are quite useful. The recent studies such s APl/Sloan Kettering for morbidity and mortality are still gathering data. As you are aware, several years worth of data are required to fully appreciate and evaluate health trends of this sort. DTH 000022285
