4 I. Introduction Laboratory wastes, whether chemical or biological, can pose a significant risk to human health and the environment if not handled correctly. The University of Texas at Tyler is committed to making sure that all wastes generated on it s campuses are identified, contained, and disposed of in accordance with applicable laws, regulations, and best management practices. The Resource Conservation and Recovery Act (RCRA) of 1976 and subsequent amendments were passed by Congress to provide the legislative basis for hazardous waste management in the United States. The Environmental Protection Agency (EPA) is the federal agency responsible for the administration and enforcement of RCRA. In Texas, the EPA has delegated authority for administrating and enforcing RCRA regulations to the Texas Council on Environmental Quality (TCEQ). EPA and TCEQ hazardous waste regulations are designed to provide for the protection of public health and the environment through stringent requirements for generators, transporters, and processors of hazardous waste. While RCRA s major focus is on the management of hazardous waste from the point of generation to the point of disposal, referred to as cradle to grave, it also covers solid waste management in general and encourages recycling and alternative energy sources. II. Hazardous Waste A solid waste is any solid, liquid, semi-solid or contained gaseous material that is discarded, abandoned, recycled, or is an inherently waste-like material... (20 CFR 261.2). A regulated chemical waste is defined as a waste which, due to its quantity, concentration, or physical and chemical characteristics may cause, or significantly contribute to, an increase in mortality or an increase in serious or incapacitating illness; or pose a substantial present or potential threat to human health or the environment when improperly treated, stored, transported, disposed of, or otherwise managed. RCRA defines a hazardous waste as a sold waste that is either characteristic or listed. A. Characteristic D Waste The EPA has identified four characteristics for hazardous waste: Ignitability, Corrosivity, Reactivity and Toxicity. Any solid waste exhibiting any one or more of these characteristics is hazardous and subject to RCRA regulation. 1. Ignitability D001 a. liquids having a flash point below 140 F b. solids that, under STP, may cause fire through friction, absorption of moisture, or spontaneous chemical changes c. certain ignitable compressed gases 4

5 d. oxidizers 2. Corrosivity D002 Any aqueous solution with a ph of less than or equal to 2 or greater than or equal to 12.5 or any liquid that will corrode steel faster than 1/4 inch per year. 3. Reactivity D003 Any wastes exhibiting one or more of the following characteristics are classified as reactive wastes and require specially storage and handling during transportation to the treatment facility. Unstable materials capable of undergoing violent chemical change (without detonating). Materials which react violently with water. Materials which form potentially explosive mixtures with water. Materials which, when mixed with water, generate toxic gases, vapors, or fumes in a quantity sufficient to present a danger to human health or the environment. Cyanide or sulfide bearing wastes which, when exposed to ph conditions between 2 and 12.5, will generate toxic gases, vapors, or fumes in a quantity sufficient to present a danger to human health or the environment. Materials capable of detonation or explosive reaction when subjected to a strong initiating source or if heated in confinement. Materials which are capable of detonation or explosive decomposition at standard temperature and pressure. Alkali metals, peroxides, and cyanide and sulfide compounds are examples of compounds that become reactive wastes. 4. Toxicity D004-D043 A solid waste whose leachate (extract) contains any of the toxic heavy metals, pesticides, or organics in concentrations equal to or greater than the regulatory levels given in the table Toxicity Characteristic Waste D004 D0043. B. Listed Waste The EPA has also designated hazardous waste to be any solid waste that is listed in one of four following lists: 5

6 1. F List F listed hazardous wastes are generic wastes from non-specific sources. Wastes on this list include spent halogenated and non-halogenated solvents as shown in table F Wastes Non-Specific Source Wastes. The F001 waste code is used ONLY for degreasing wastes. 2. K List K listed hazardous waste are specific wastes from specifically identified industries (sources). This does not apply to UTT. 3. P and U Lists P and U listed hazardous wastes are discarded commercial chemicals, offspecification chemicals, and container or spill residues from such compounds, including unused laboratory chemicals. P listed wastes (Acute Toxic Hazardous Waste P List) are acute hazardous waste, and no more than 1 kg of such waste may be generated in any one month, while U listed wastes (Toxic Hazardous Waste- U List) are toxic waste. Note: If the waste is spent (not in its original form), these lists do not apply. III. Special Waste Many laboratory chemicals used at UT Tyler are known to be toxic or otherwise hazardous but are not characteristic or listed wastes and therefore not RCRA hazardous wastes. Examples include ethidium bromide. The TCEQ recognizes this and has developed a waste category for these special wastes. A special waste is any solid waste that is not regulated as hazardous but because of its quantity, concentration, physical and/or chemical characteristics, or biological properties requires special handling and disposal to protect human health and the environment. The following are considered special waste: 1. Biological/medical (biomedical) waste including research animal tissues or carcasses, cultures, and sharps (razor blade, syringe needles) 2. Waste whose toxic constituent concentration falls below the regulatory limits for the toxicity characteristic 3. Petroleum products, including oil and oil filters 4. Empty hazardous chemical containers 5. Light ballasts and small capacitors containing PCBs 6. Asbestos (friable) 7. Lead acid and Nickel/Cadmium (NiCad) batteries 6

7 IV. Waste Management Guidelines These guidelines are very important to avoid unnecessary handling and/or costs and to comply with federal and state regulations. 1. Never discard hazardous or special waste down the drain ( City Of Tyler Drain Discharge Prohibitions) or into the trash. These wastes must be collected for proper disposal. 2. Establish a Satellite Accumulation (SA) area in each laboratory where wastes will be generated. EH&S will help determine the best location for your SA and will provide appropriate labeling as well as emergency telephone number labels. 3. Label each container (Chemical Waste Label) and place in your SA area. Make sure each container has a tight-fitting lid. Principal component (excluding water) should be listed on label if it is a mixture. Labels templates are available from EH&S for small (Avery Label #5294) and large (Avery Label #5164) waste labels. 4. All containers must be clearly identified and labeled with the proper chemical name(s) of the substance(s) at the start of collection. Trade names, acronyms, abbreviations, codes, or formulas are not acceptable. 5. Do not accumulate waste in containers greater than five gallons and do not fill the waste containers entirely; leave a adequate space (such as the entire neck of the bottle) at the top so the contents of the container can be transferred without spillage. 6. Do not mix organic and aqueous waste together in the same waste container. Water decreases the BTU value of flammable organic solvents and therefore reduces its usability as a fuel. 7. Do not mix halogenated organic solvent waste with non-halogenated organic solvent waste. Most halogenated organic solvents are persistent environmental hazards and expensive to dispose of and therefore should be kept separate from other wastes. 8. Evaporation of solvents, especially chlorofluorocarbons (CFCs), for the purpose of disposal is not permitted. 9. Inexperienced laboratory personnel should not perform neutralization of acid and bases waste; instead, contact EH&S for disposal. Bulk neutralization of acid and base waste is prohibited. If experienced personnel perform neutralizations of trace amounts of acid and base waste in the lab, be certain that there are not other hazardous constituents in the wastes and that neutralization is complete and within the City of Tyler drain disposal limits (page 16) before disposing down the drain. Such solutions must have a ph between 5.5 and 10.5 be relatively non-toxic, and not exceed specific metal limits. 10. Some empty containers of chemicals can be disposed of in the ordinary trash. At UT Tyler a chemical container is considered empty if all material has been removed and the container is tripled rinsed with appropriate solvent and the rinsate being handle as hazardous waste. If uncertain about what the appropriate solvent is to use with a particular chemical, or how to triple rinse to minimize generation of hazardous waste, please contact EH&S for assistance. 11. Do not discard into the trash empty chemical containers that contained any of the following: acids, bases, solvents, or any P or U listed chemicals. These 7

8 containers must be rendered unusable before disposal. All empty containers of chemicals must be triple rinsed with an appropriate solvent prior to disposal. The waste solvent must be disposed of as hazardous waste. An alternative is to dispose of the container as hazardous waste. University faculty and staff should contact EH&S at 7011 for guidance on how to prepare these containers for disposal. 12. Spent lubricating oils must be collected for recycling purposes; therefore, do not contaminate with any other wastes. 13. Prevent unknowns by keeping all waste containers labeled. The burden of identifying unknowns lies with the laboratory generating the unknown and not EH&S. Wastes will generally not be accepted if the contents are not known. V. Disposal Procedures Environmental Health & Safety (EH&S) provides chemical and special waste pickup and disposal services for U Tyler. These services are provided at no cost to the requesting department; however the following guidelines must be followed to ensure compliance with federal and state laws and to avoid unnecessary handling and/or costs. A. Chemical Waste 1. Procedure a. Fill out an accumulation log (page 18) using the same waste log number as on the label. This log sheet is required for each waste container. b. The Chemical name (spelled out, no abbreviations or structures), CAS#, solvent (if applicable), must be listed as each waste is added to the container. Identify all chemicals in the waste, including water (unknowns are not acceptable) When container is full, add percentage of each component present. c. Make sure that all wastes are chemically compatible before placing in the container. d. Use only chemically compatible containers and label (page 20) properly. e. Wastes must be segregated according to the type of hazard present. f. Use a waste label to identify the waste, the location, the log sheet number, and the responsible person. The generator is responsible for the identification of the waste. However, if the generator cannot positively identify the waste, the waste will be sent to a contract laboratory for analysis and the generator will be billed for the analytical costs. g. Complete the Chemical and Physical Hazard section. 2. Disposal a. Unless actively receiving wastes, container should be stored in the SA area with the cap securely in place. b. When the waste container is full call the EH&S office at and tape a copy of this waste log to the container. 8

9 B. Biological Waste Bio waste - any solid waste or a combination of solid wastes that because of its quantity or biological properties requires special handling and disposal to protect human health and the environment. Bio waste includes, but is not limited to: infectious and pathological materials from health care facilities, veterinary hospitals or laboratories; such wastes are those containing pathogens or biologically active material that, because of its type, concentration and quantity, is capable of transmitting disease, and any animal tissues or carcasses in need of disposal. 1. Procedure a. Appropriately marked and labeled containers and boxes with liners will be stored for accessible use at collection sites. Collection sites include designated classrooms and laboratories. b. Collection of waste will be coordinated by EH&S. Collection boxes, liners, sharps containers, and red bags are available from EH&S. c. Animal body parts that have been intentionally exposed to pathogens are treated to kill infectious organisms and placed in sealed containers. d. Needles and glass are placed in appropriate sharps containers and sealed. e. All other biomedical waste are placed directly in appropriate biomedical waste containers and sealed. f. All animal carcasses used in laboratories for teaching/research purposes and need disposal. g. Personal protective equipment will be worn when handling biomedical waste. When biomedical waste containers are filled to the maximum level at the site of collection, they are properly sealed and stored pending pick up by EH&S. 2. Collection And Disposal a. When biomedical waste is ready for pick up from a collection site, the respective department will complete the Biowaste Collection Form (page 21). b. Call EH&S at 7011 to arrange for waste pickup. EH&S will pick up the waste and store it in a central location. c. All waste will be picked up from the approved collection sites. Do not place waste in corridors. d. Labeled waste is picked up from a central storage location by an approved contractor, as requested by EH&S. The contractor transports the waste to an approved waste management company for incineration. Records of incineration and completed waste collection forms are kept on file in the EH&S office. VI. Pollution Prevention The following are some source reduction and waste minimization guidelines to assist you in reducing the hazardous waste that your lab generates. 9

10 1. Minimize mixing hazardous waste with non-hazardous waste, such as water. Do not dilute hazardous waste. This not only increases the volume necessary for disposal, but may also affect any reusable properties of the waste, such as BTU value. The only exception is adding water to explosive chemicals to keep them wet. 2. Segregate your waste according to waste streams such as: non-halogenated organic solvent waste (no water); halogenated organic solvent waste (no water); photo fixer waste; aqueous waste with non-halogenated organic solvents; aqueous waste with halogenated organic solvents; aqueous waste with toxic heavy metals; aqueous acidic waste; aqueous basic waste; metallic mercury waste; lubricating oil; formalin; and ethidium bromide, etc. 3. Avoid contamination of stock chemicals. Unused portions of a chemical should not be returned to its original container. Estimate how much of a chemical will be needed for an experiment to avoid removing more chemical than is needed. For teaching labs, preweigh chemicals for undergraduate usage. 4. Substitute less hazardous chemicals in experiments whenever possible. 5. Use spirit-filled thermometers instead of mercury-filled thermometers. 6. If only a small amount of a chemical is needed, ask around other labs before ordering. 7. Avoid buying chemicals in bulk. Cost of disposal usually outweighs any savings obtained by buying in bulk. 10

18 IX. FORMS The following forms may be filled out and sent via campus mail or electronically to request a pickup of material. 17

19 A. Chemical Waste Accumulation Log Waste Log Number Date: Dept: Bldg Room Extension: This log sheet is required for each waste container. The Chemical name (spelled out, no abbreviations or structures), CAS#, solvent (if applicable), quantity and concentration must be listed as each waste is added to the container. Make sure that all wastes are chemically compatible before placing in the container. Use only chemically compatible containers and labeled properly. Wastes must be segregated according to the type of hazard present. The proper name for all wastes will be Waste followed by the chemical name. Use a waste label to identify the waste, the location, the log sheet number, and the responsible person. The generator is responsible for the identification of the waste.
