In the first part of this series, which appeared in the April/May 1998 issue, we discussed the identification and classification of hazardous waste. In this article, we’ll look at the classification of waste generators and waste-handling techniques and provide tips on preparing for an emergency and choosing a disposal firm.

Categorically speaking
It’s possible that you could fall into one of three categories:

  • Conditionally Exempt Small-Quantity Generator (CESQG)
  • Small-Quantity Generator (SQG)
  • Large-Quantity Generator (LQG) (Some states do not distinguish between CESQGs and SQGs) To determine which category describes your status, you must measure the wastes listed below on a monthly basis:
  • Hazardous wastes generated that have accumulated on site.
  • Hazardous wastes generated and transported off-site for treatment, storage or disposal.
  • Hazardous sludges or water removed from fuel or waste oil storage tanks.
  • Used waste oil that has been mixed with a listed hazardous waste.
  • Used waste oil that is not to be recycled.
  • Waste water in rack or lift pits, and oil/water separators that have hazardous waste in them.
  • Sludges from floor drains or traps that have hazardous wastes in them. Do not include any specifically exempted materials (such as lead-acid batteries) that will be reclaimed, used oil that will be recycled under the used-oil provision or materials that are reclaimed continuously on site without storage, such as antifreeze recycling.


    Don’t waste these tips
    How do you manage hazardous and special wastes? Keep the following tips in mind. To ensure proper handling of your wastes, read and follow all applicable federal, state and local regulations.

    Used oils
    Used oil that is recycled, re-refined, reprocessed or burned for energy is exempt from federal rules for classification as a hazardous waste. Keep your collection tanks or drums closed and labeled, in good condition and secure. Inspect frequently for leaks, corrosion or spillage. Never mix other liquids such as solvents, flammables, antifreeze or water with used oil. Do not dispose of used oil in sewers, drains, waste dumpsters or on the ground, or use as dust or weed control. Have procedures that minimize spillage on the shop floors. Immediately clean up all spills of used oil. Use a transporter who is properly licensed and registered with the state. Keep a record of all used oil generation and disposal.

    Used oil filters
    Properly drained used oil filters are not subject to federal hazardous waste rules. EPA defines proper draining of filters as: Puncturing the filter dome and draining hot — at above room temperature to near engine operating temperature. Filters should be drained for a minimum of 24 hours. Be sure to check state regulations and local landfill bans.

    Used antifreeze
    For waste antifreeze, the regulatory or best-management requirements are as follows: Store used antifreeze in an appropriate container. Keep the container closed, labeled and secure. Inspect frequently for leaks, corrosion or spillage. Label container with the words "Used Antifreeze." Never mix other liquids such as oil, solvents and flammables with used antifreeze. Used antifreeze should be recycled. Keep a file of all waste antifreeze generation and disposal records.

    Used parts-cleaning solvent
    Most parts-cleaning solutions contain solvents or mineral spirits, have a flash point below 140°F and may contain contaminants. Because of this, vehicle maintenance facilities are required to do the following: 1. Verify that used solvent is recycled or burned for energy.
    2. Not use used solvent to clean shop floors.
    3. Properly label solvent tanks.
    4. Keep a record of all used solvent generation and disposal. There are a number of other wastes potentially generated in the operation of a vehicle maintenance facility. Each of them has specific requirements for handling, storage and disposal. Be sure to check all applicable federal, state and local regulations. These wastes include:

  • Used shop rags.
  • Used oil-dry material.
  • Used lead-acid batteries.
  • Used painting supplies.
  • Used drums.
  • Fuel drained from tanks or vehicles.
  • Oil/water separator sludges.


    Store it properly
    When you accumulate hazardous waste in containers you must:

  • Use containers that are compatible with the hazardous waste held in them.
  • Store in secure, contained area.
  • Inspect containers regularly for leaks and deterioration.
  • Properly label containers with accumulation start date, the words "Hazardous Waste," composition and physical state of the waste and name and address of the generator. (There are standard labels available to help you do this.)


    Ready for an emergency?
    You must be prepared for an emergency at your facility. The EPA does not require a CESQG or a SQG to develop a written contingency plan, but each is required to have basic safety guidelines and response procedures in an emergency. SQGs and LQGs are required to designate an Emergency Coordinator who must be able to respond and implement the contingency plan. All generators are required to provide training for their employees. LQGs are required to have a formal employee training program that teaches hazardous waste management and emergency response procedures. SQGs, on the other hand, have no formal requirements under the federal Resource Conservation and Recovery Act (RCRA), but employees must know what to do in case of an emergency. In general, employees should be trained to notify the appropriate emergency personnel and monitor the area of the spill or leak to make sure other employees do not go near it. They should also evacuate the area or assist in the evacuation and initiate specific emergency response procedures to assist in emergency control or clean-up procedure. Facilities that generate more than 220 pounds of hazardous waste within any one calendar month must notify the EPA of their activity through a clearly defined manifest system. The manifest provides a standardized record-keeping and tracking system — following each waste from its point of generation to its final disposal. The generator, the transporter and the disposal/treatment facility must each sign the manifest. All SQGs and LQGs must keep the following records for a minimum of three years. (An indefinite retention time is recommended.)

  • Manifests, including all copies from transporters and destination facilities.
  • Notice of land disposal restriction.
  • Exception reports.
  • Laboratory test results.
  • EPA ID number.
  • Waste characterization/analysis.
  • Written plans.
  • Employee training attendance sheets. Also retain any correspondence regarding the hazardous waste transporter and the treatment/storage/disposal facility and records of site visits. For SQGs and LQGs, a biennial report of hazardous waste activity is due to your EPA regional office by March 1 of even-numbered years.


    Choosing a disposal firm
    As the generator, you have "cradle to grave" responsibility and liability for hazardous wastes. Because of the long-term financial risks, it is especially important to use good judgment in the selection of your waste service firm: Always deal with a firm that has an EPA ID number and has obtained the proper EPA permits. This does not limit your liability, however, and is not a guarantee that the firm is in compliance with state or federal rules. Consider an on-site visit and/or conduct an audit of the processing facility. If you can’t visit the final destination, visit the local transfer station. Consider using a full-service firm. This is not always possible, but dealing with one firm that transports and processes your wastes makes it easier to monitor and manage. Check with your state environmental agency to see if the firm has current or past problems. Are there any past or pending lawsuits or actions filed against the company? Check with your colleagues, industry and professional associations and other businesses or consultants for references or recommendations. Be cautious of unusually low pricing. It may cost more to use a more expensive firm but consider the cost difference in terms of environmental liability insurance. The firm you choose should:

  • Assist in manifesting, waste sampling and analysis (if required), and offer a flexible pick-up schedule.
  • Have undergone a rigorous environmental audit from a third party.
  • Be financially stable.
  • Maintain adequate environmental insurance for accidental spills and long-term environmental liability.
  • Not be under any significant orders, actions or claims from government or individuals.
  • Have an environmental and safety program.
  • Provide you with spill, environmental and safety records.


    Practice the three Rs
    The best waste management practice is to not produce the waste in the first place! Good housekeeping and common sense are the cornerstones to sound environmental management. Waste reduction is largely dependent upon these factors and the three Rs — Reduce, Reuse and Recycle. To practice the three Rs, keep the following in mind:

  • Do not mix non-hazardous wastes with hazardous wastes.
  • Do not mix other waste liquids with used oil. You may render the entire quantity of used oil a hazardous waste by doing so.
  • Avoid mixing several different hazardous wastes. This may also make recycling more difficult, if not impossible, and increase treatment/disposal costs.
  • Avoid leaks and spills. Clean-up materials may also be hazardous. Frequent leaks and spills are most likely caused by carelessness and can easily be reduced.
  • Make sure you empty all containers and aerosol cans prior to disposal.
  • Purchase only what you need.
  • Use the least hazardous substance for a particular job.
  • Take immediate action when a release or threatened release of a hazardous substance or waste is suspected or confirmed.
  • Wherever possible, recycle hazardous materials.
  • Implement a training program for employee environmental awareness.
