Sierra Chemical Co. <br />Hazardous Waste Management Plan <br />• All waste has been removed that can be removed <br />• less than 1 inch of the residue remains in the container <br />• No more than 3% by weight of the total capacity of the container remains in the container sized <br />lessor equal to 110 gallons; or <br />• No more than 0.3% <br />by <br />weight of the total <br />capacity of the container remains in the container <br />sized 110 gallons. <br />materials, each of which could <br />be classified as a hazardous waste: <br />343. <br />If the containers are not "empty" per the requirements listed above, they must be treated as hazardous <br />waste. Containers should be identified as "empty" to ensure proper disposal. Empty labels are provided <br />in Appendix C. <br />5.4 Contaminated Rags and Absorbents <br />ndustrial rags, also referred to as wipes and absorbents, are typically constructed of absorbent fabric or <br />a related material and used for general equipment cleaning to clean oil, grease and dirt from parts. <br />Whether soiled wipes, absorbents or rags are considered a hazardous waste depends on the type of <br />residues and materials remaining on the absorbent after use. As with any other waste, it is up to the <br />generator to determine the regulatory status of each waste generated and manage them appropriately. <br />Currently, Sierra Chemical Co. has determined that rags and absorbents used to clean up spills involving <br />hazardous materials, including oil are hazardous wastes. Federal regulations listed in 40 CFR and CA <br />specific regulations listed in 22 CCR, define materials that are contaminated with one or more listed <br />wastes or listed by the state of CA as a "non-RCRA" hazardous waste, as hazardous waste and require <br />that they be disposed of in compliance with all applicable laws and regulations. <br />S.S Aerosol Cans <br />An aerosol can typically become waste when 1) the can has lost it's spray nozzle before the contents <br />have been completely used, 2) the aerosol can run out of propellant before the contents have been <br />completely used, 3) the generator no longer has a use for that product, or 4) the product has been <br />completely used and the empty can remains. <br />Aerosols <br />cans pose a unique hazardous <br />waste determination problem due to <br />the fact that they consist <br />of three <br />materials, each of which could <br />be classified as a hazardous waste: <br />343. <br />• The can itself; <br />• The liquid product contained in the can (characteristic orlisted); and <br />• The gaseous propellant (reactive, that is, it is capable of detonation or explosive reaction if it is <br />subjected to a strong initiating source or it is heated under confinement). <br />They can be managed in one of two ways: <br />• Recycled <br />as <br />a scrap metal (see <br />below for requirements prior to meeting this exemption); or <br />• Disposed <br />as <br />hazardous waste <br />343. <br />Sierra Chemical Co. <br />has chosen to manage <br />their waste aerosol cans as <br />hazardous waste under the <br />Federal EPA wastes <br />codes D001 and D035 <br />and the CA EPA waste code <br />343. <br />Disposal of aerosol cans as anon -hazardous waste may only occur if: <br />Prepared By: <br />Issue date: <br />Replaces: <br />Page: <br />ACT Environmental Services, Inc. <br />March 4, 2016 <br />NA <br />12 of 23 <br />
