Box 50426 ENVIRONMENTAL HEALTH <br /> Yndianapolis, Indiana 46230-0426 PERMIT/SERVICES <br /> Dear Mr. Peterson: <br /> REGULATiON OR FERROUS SULFATE GENERATED FROM OXSITE SULFURIC ACID <br /> RECYCLING <br /> Thins is in roar on2Q to your Cctobe�r 23, 1991 request for <br /> info=ation concerning the regulation of ferroug sulfate orystalls <br /> which aro ganaratod from onsite sulfuric acid recycling <br /> oporationa, It Jo aur understanding that Crown Technology Ina. <br /> manufacturoarss and mark4tss in-lino acid regeneration equipment, <br /> sons of whioh produce ferrous sulfate crystals as a by-product of <br /> acid recovery. Ferrous sulfate is typically used in water <br /> treatment, fertilizer, food supplaament, paint pigment, and other <br /> applications. <br /> It is our undor6tanding that the United States Environmental. <br /> protection Aganoy (Va WA) would not regulate ferrous sulfate <br /> crystals because they do not: exhibit a characteristic of a <br /> ham&rdouja waoto within federal waste characterization guidolinee. <br /> if the crystals did exhibit a charavteristic of a hazardous waste <br /> under the federal guidelines, they would probably not be <br /> regulated as a waste since trey would ba considarod a by-product <br /> that is to be recl.aitted (Section 261.21 Title 40 of the anode of <br /> Federal Regulations) . <br /> Ferrous sulfate crystals have been shown to be toxic at <br /> levoin which are regulated in California. wriaretore, recovered <br /> crystals arae regulated as hazardous waste in California unless <br /> they are excluded from regulation as provided in the recyclable <br /> material exclusions or exemptions found in Section 25143.2, <br /> Chapter 6. 5, Division 20 of the Health and Safety Coda (HSC) . <br /> The recyclable material proviciono•contain two provisions <br /> that would allow onsite recycling to coeur without further <br /> authorization from the Departnent. Section 25143.2(c) (2) , H50 <br /> allows onsite recycling of Resource, conservation +Ind Recovery <br /> Act (RCRA) or non-MRA hazardous waste without a hazardous waste <br /> facility permit if the following conditional aro met. <br /> The material is recycled and mo*d at the facility at <br /> whioh the material was 9en0=t0d, <br />
