Dept, of Biostatistics School of Hygiene and Public Health Jdhns Hopkins University 615 N. Wolfe St. Baltimore, HD 21205 Dear Richard: Schwartz to your continued concerns regarding ms nancmng o t tne uuKont criticisms of his work (re: your letter of August[20 to me). I have enclosed a copy of that response for your review, along with another memo to which he refers in his cover letter. If there is any way that you could read over this material and send me a copy of your evaluation of it by the end of October, I would be very grateful indeed. I have reviewed the status of your contract with us, and find that there are 5 consulting days left on it for which you have not submitted an invoice. I would think that this should be sufficient time to finish this last lingering task; if you will submit an invoice along with your evaluation, I will have it processed immediately. Thank you for your continued help and cooperation in this matter, Richard. I sincerely hope that this is the last time that I will have to interrupt your schedule, at least for lead?. Best wishes, David E. Weil, Ph.D. Project Manager Air Quality Criteria Document for Lead TEH 0412420
