We have a hospital in Lodi that is adding a new wing and they want to install a <br /> decontamination tank for emergency response/emergency preparedness. This tank would receive their rinsate <br /> from washing off people contaminated with unknown materials. I have attached their letter explaining the <br /> purpose of the tank. <br /> Historically, people in this area have been exposed to pesticides and other fumigants related to agriculture but <br /> any chemical used in any local industry could contaminate people and find its way into this tank. This tank is <br /> being installed to immediately rinse off people prior to entering the hospital to prevent contamination of the rest <br /> of the hospital staff. <br /> We told them this would be considered an underground storage tank and we would have to review the plans. <br /> Somebody else told them they might be exempt. I didn't consider them exempt because, in my mind, it didn't fit <br /> the exemption definition"An emergency containment tank kept empty to receive accidental spills and approved <br /> for such use by the appropriate local agency"as the tank is designed to collect decon liquid not accidental spills. <br /> In the event it can possibly be considered an exempt tank it is my understanding it must still be designed and <br /> installed pursuant to the current laws/regulations and that would mean VPH, is that correct? <br /> The minimal plans they submitted show a double-wall"approved vinyl ester resin or equivalent lined"Xerxes tank <br /> with single-wall cast iron piping without cathodic protection. There is a limited 1 year warranty for"chemical <br /> tanks"from Xerxes referenced on the plan, not sure how that would fit in to an approval. It will be difficult for <br /> them to show this tank's compatibility with what is stored because that is an unknown. Any suggestions on how <br /> to deal with this would be appreciated. <br /> Please let me know if you think it would be excluded from regulation altogether or could be considered exempt <br /> and if exempt if it there is a way around installing VPH. <br /> Thanks for any help. <br /> Kasey Foley, REHS <br /> Program Coordinator <br /> San Joaquin County Environmental Health Department <br /> 600 East Main Street <br /> Stockton, CA 95202-3029 <br /> (209) 468-3451 <br /> kfoley@sicehdcom <br /> 6/20/2008 <br />
