Hazardous Waste Disposal

Hazardous Waste and Texas A&M University

      Hazardous waste disposal is governed by the EPA and the TNRCC through State and
      Federal regulations. The purpose of environmentally sound disposal methods is to prevent
      harm to the water, land, and air.

      TAMU complies with hazardous waste disposal regulations by means of the Hazardous
      Waste Management Program and TAMU Policy and Procedure Manual, section 5.3.1,
      "Hazardous Waste Disposal Plan". This program is available from the Environmental Health
      & Safety Department.

Permits and Requirements

      TAMU is a "Large Quantity Generator" of hazardous waste. The University's generator
      permit applies to all System Parts in College Station and Brazos County. Unlike the main
      campus, other System Parts may be "Small Quantity Generators" or "Conditionally Exempt
      Small Quantity Generators." Since each category has specific requirements and regulations,
      System Parts must determine the regulations that apply to their site and attain the correct
      permit. The Environmental Health & Safety Department will assist any department or System
      Part in determining its hazardous waste disposal needs.

Penalties of Noncompliance

      Noncompliance with any hazardous waste regulation may result in substantial fines and
      penalties for the University. In addition, individual generators may be personally liable.
      Generators may be cited or fined for numerous types of violations. Violations range from
      improperly labeling a waste container to intentionally disposing of hazardous waste
      incorrectly.

Role of the Environmental Health & Safety Department

      The Environmental Health & Safety Department administers the Hazardous Waste
      Management Program at TAMU. Compliance with this program is very demanding — it
      requires full cooperation by all campus entities. The main focus of this program is chemical
      waste management. The program does not include procedures for the management of
      radioactive, infectious, biological, or nonhazardous waste.

      The Environmental Health & Safety Department collects, transports, and stores hazardous
      waste until it is shipped for final disposal. EHSD also maintains permanent records of all
      disposed waste. Contact EHSD for more information on hazardous waste disposal.

Definitions

Central Accumulation Area
      Area(s) designated by the Environmental Health & Safety Department to be used for the
      storage of hazardous wastes prior to shipment to permitted disposal facilities.

Disposal
      The discharge, deposit, injection, dumping, spilling, or placing of any solid waste or hazardous
      waste (whether containerized or uncontainerized) into or on any land or water so that such
      solid waste or any constituent thereof may enter the environment or be emitted into the air or
      discharged into any water, including ground waters.

Generator
      Any person, by site, who produces municipal hazardous waste or industrial solid waste; any
      person who possesses municipal hazardous waste or industrial solid waste to be shipped to
      any other person; or any person whose act first causes solid waste to become subject to
      regulation.

Hazardous Waste
      Any solid waste material listed or identified in Title 40 Code of Federal Regulations, Part
      261, Subpart C or D or exhibiting the characteristics of ignitability, corrosivity, reactivity, or
      E.P. toxicity also defined in Part 261. Tables containing the listing and characteristics of
      hazardous wastes are shown at the end of this chapter.

Mixed Waste
      A radioactive waste that is also a hazardous waste.

Satellite Accumulation Area
      An area, system, or structure for temporary accumulation of hazardous waste prior to
      transport to the central accumulation area.

Solid Waste
      Any garbage, refuse, sludge from a waste treatment plant, water treatment plant, or air
      pollution control facility or other discarded material. Solid waste can be solid, liquid,
      semi-solid, or contained gaseous material resulting from industrial, municipal, commercial,
      mining and agricultural operations, and from community and institutional activities.

Waste
      Any useless and valueless material that is to be discarded.

Types of Hazardous Waste

      An item is considered waste when the owner determines that the material is no longer useful
      and needs to be discarded. An item is considered to be hazadous waste if it meets one or
      more of the following characteristics:

• A chemical component is listed on one of the Chemical Tables included at the back of this chapter.
• Mixture contains a listed hazardous waste and a nonhazardous waste.
• Material meets the definition of one of the following:                                                -Ignitability (flashpoint < 60^o C or supports combustion)                                          -Reactivity (e.g., water reactives, cyanides, explosives, unstable chemicals)            -Corrosivity (ph < 4 or > 10)                                                                                           -EP toxicity (e.g., pesticides, heavy metals, poisons)                                                  -Material is not excluded from regulations.

      Individual departments are responsible for properly identifying the hazardous waste they
      generate and for following University disposal procedures. Refer to the Chemical Tables
      section in this chapter for list of regulated hazardous chemicals.

Containers, Tags, and Collection

      Proper containment, tagging, collection and disposal are essential to the success of the
      Hazardous Waste Program. The following sections discuss these areas.

Filling Containers

      Hazardous waste collection containers must be in good condition, must not leak, and must be
      compatible with their hazardous contents (e.g., do not use metal containers for corrosive
      waste or plastic containers for organic solvents). All containers must have suitable screw
      caps or other secure means of closure. When large waste containers (greater than 10 gallons
      total volume) are warranted, contact the Environmental Health & Safety Department for
      assistance.

      If you are reusing a container to accumulate waste, destroy the original product label. EPA
      regulations require that waste containers be labelled with the accumulation start date, the
      identity of the contents, and the words "Hazardous Waste". Use a new label to identify the
      hazardous waste, do not use the disposal tag for this purpose.

           IMPORTANT:

          Never overfill hazardous waste containers. Expansion and excess weight can lead to
          spills, explosion, and extensive environmental exposure.

      Hazardous waste containers for liquids are generally rated by volume capacity. Allow extra
      room in liquid containers to allow for contents expansion.

• Do not fill jugs and bottles past the shoulder of the container. The shoulder of the container is the place where the container slopes in towards the neck.
• Fill closed head cans (5 gallons or less) to leave approximately two inches of space between the liquid level and the top of the container.
• Fill closed head drums (larger than 5 gallons) to leave approximately four inches of space.

      Hazardous waste containers for solids are generally rated by their weight capacity and
      volume capacity. Take care not to exceed the weight capacity of a solid container. Weight is
      generally not a problem for jars and open head cans (5 gallons or less), but it can be a
      problem for open head drums (larger than 5 gallons). Depending on weight requirements,
      you may fill containers for solids within two inches of the closure.

          IMPORTANT:
          Keep all waste collection containers closed except when adding or removing
          material.

Completing Tags

      When a container is ready for disposal, complete a waste tag (available from the
      Environmental Health & Safety Department) and attach it to the container. A waste disposal
      tag must be attached to each waste container before disposal. A sample Chemical Waste
      Disposal Tag is included on the following page.

      Follow these guidelines for completing hazardous waste tags:

• Completely fill out both the upper and lower sections of the tag. (This information is essential for record keeping.)
• The "REQUESTOR" is the person in charge of the lab.
• Use full chemical names or common names. Chemical formulas or abbreviations are not acceptable.
• List all chemical components in the waste container, including water. Long lists may be continued on the back of the tag.
• Indicate the percent concentration of potentially explosive materials such as picric acid and nitro compounds.
• Place additional hazard information in REMARKS.
• Attach the tag to a string which encircles the container. Rubber bands, tape, and wire are not acceptable.

      After completing the tag, attach the top part of the tag to the container and mail the bottom
      part of the tag to the Environmental Health & Safety Department at MS 4472.

REMARKS:

Collection and Disposal

      After receiving a properly completed waste disposal tag, the Environmental Health & Safety
      Department will collect the waste.

      Containers with improper caps, leaks, outside contamination, or improper labeling will not be
      picked up until these problems have been corrected.

      Improper disposal methods for hazardous chemical waste include the following:

• Disposal down the drain.
• Intentional evaporation in a fume hood.
• Disposal in the regular trash.

Disposing of Empty Containers

      What do I do with empty chemical containers? How do I get rid of them? Can they be
      placed in the trash dumpster? These are questions frequently asked by TAMU personnel.
      The answer is fairly simple but very important.

      EPA regulations stipulate that empty containers must meet the following requirements:

• Containers must not contain free liquid or solid residue.
• Containers must be triple rinsed.
• Product labels must be defaced or removed.
• Container lids or caps must be removed.

      Punch holes in the bottom of metal containers and plastic jugs before disposing of them in the
      regular trash. It is not necessary to break empty glass containers.

          IMPORTANT:
          Containers that do meet the requirements mentioned here must be treated as
          hazardous waste.

Minimization and Substitution

      The cost of commercial waste disposal continues to rise and the amount of waste generated
      continues to increase. TAMU cannot control disposal costs, but it can reduce the amount of
      waste generated. The following sections discuss how to minimize waste sources and waste
      products.

Waste Source Reduction Techniques

      Use the following techniques to reduce waste sources:

Purchasing and Inventory Control

• Use computerized tracking systems to manage purchasing and control inventory.
• Maintain current inventory records to prevent overstocking and to monitor the shelf life of remaining chemicals.
• Develop a campus-wide chemical exchange network to promote chemical sharing and avoid redundant purchases.
• Negotiate with suppliers to gain volume discounts, flexible delivery schedules, and delivery of fewer small-sized containers without cost penalties.
• Purchase quantities for immediate use only. Do not order quantities to obtain a special unit cost savings.
• Obtain compressed gases from vendors who accept return of empty or partially full cylinders.
• Include waste generation as a criteria in equipment selection.
• Rotate chemical stocks to use chemicals before their shelf-life expires.

Chemical Usage

• Use lab procedures that assure the integrity of chemical quality.
• Reduce spills and waste by pre-weighing chemicals for undergraduate use.
• Require proper labeling of all secondary containers. Replace all deteriorating labels on primary and secondary containers.
• Substitute less hazardous chemicals whenever possible (e.g., biodegradable scintillation cocktails instead of xylene or toluene-based cocktails).
• Minimize the use of heavy metals (e.g., silver, chromium, mercury, barium, cadmium, and lead).
• Substitute alcohol or electronic thermal monitors for mercury thermometers.
• Use "No-Chromix", detergents, or enzymatic cleaners to clean laboratory glassware.
• Minimize solvent waste by recycling or substitution.

Waste Minimization Techniques

     Follow these techniques to reduce hazardous waste:

• Establish a Faculty Task Force to review waste streams and recommend waste minimization procedures.
• Do not mix different types of waste.

          - Do not put non-hazardous waste, such as a mixture of water, sodium bicarbonate, and
            acetic acid, into a waste container of hazardous waste .
          - Do not combine inorganic heavy metal waste with organic solvents waste.
          - Segregate halogenated waste solvents from non-halogenated waste solvents
 

• Segregate waste streams by storing them in separate waste containers. Store waste containers separate from reagent containers being used to avoid accidental contamination.
• Decontaminate empty containers to make them non-hazardous.
• Neutralize dilute acids and bases to make them non-hazardous and suitable for drain disposal.
• When possible, redesign experimental protocols so that harmful byproducts are detoxified or reduced.
• Recycle chemicals via purification.
• Make lab employees accountable for waste when labs are decommissioned.

Segregation

      Segregated waste is safer and easier to dispose of than nonsegregated waste. Mixed waste,
      for example, must be handled as both radioactive waste and hazardous waste.

      Each employee who generates waste is personally responsible for the following:

• Ensuring that hazardous wastes are accumulated in safe, transportable containers.
• Ensuring that hazardous wastes are stored properly to prevent possible exposure.

      In addition to the guidelines for waste minimization and substitution, follow these guidelines for
      waste segregation:

• Segregate waste into the following groups:

          •Halogenated solvents
          •Non-halogenated solvents
          •Acids
          •Bases
          •Heavy metals
          •Poisons
          •Reactives

• Do not mix non-hazardous waste, such as water, with hazardous waste.
• Do not combine inorganic heavy metal waste with organic solvent waste in hazardous waste containers.
• Double-bag dry materials contaminated with chemicals (paper, rags, towels, gloves, or kim wipes, etc.) in heavy-duty plastic bags. Do not use biohazard bags. Dispose of these items in the same manner as hazardous waste.
• Encapsulate sharps (e.g., needles, razor blades, etc.) then place them in trash dumpsters.
•

Special Concerns

      Employees who generate hazardous waste must maintain and control their hazardous waste
      accumulation areas. Special concerns for hazardous waste include the following:

• Unneeded chemicals that are to be discarded must be handled and managed as hazardous waste.
• Unknown chemical waste will be picked up by Environmental Health & Safety Department Departments will be charged for the chemical analysis to determine proper disposal method.
• Gas cylinders are extremely difficult to discard. They should be returned to the manufacturer or distributor whenever possible. Cylinders that cannot be returned should be tagged as hazardous waste as soon as possible.
• Photographic chemicals containing silver may not be placed in the sanitary sewer. They must be disposed of as hazardous waste.

NOTE:
Some developing equipment has a filter to capture silver before the photographic effluent enters the drain. Please notify the Environmental Health & Safety Department if you have this type of equipment.

The following materials or items are hazardous wastes if and when they are discarded or
intended to be discarded as described in 40 CFR 261.2(a)(2)(i), when they are mixed with
waste oil or used oil or other material and applied to the land for dust suppression or road
treatment, when they are otherwise applied to the land in lieu of their original intended use or
when they are contained in products that are applied to the land in lieu of their original
intended use, they are produced for use as (or as a component of) a fuel, distributed for use
as a fuel, or burned as a fuel.

(a)    Any commercial chemical product or manufacturing chemical intermediate having the
        generic name listed in paragraph (e) or (f) of this section.

(b)    Any off-specification commercial chemical or manufacturing chemical intermediate
         which, if it met specifications, would have the generic name listed in paragraph (e) or (f)
         of this section.

(c)     Any residue remaining in a container or in an inner liner removed from a container that
         has held any commercial chemical product or manufacturing chemical intermediate
         having the generic name listed in paragraphs (e) or (f) of this section, unless the container
         is empty as defined in 40 CFR 261.7(b) of this chapter.

[Comment: Unless the residue is being beneficially used or reused, or legitimately
recycled or reclaimed; or being accumulated, stored, transported or treated prior to
such use, re-use, recycling or reclamation, EPA considers the residue to be intended for
discard, and thus a hazardous waste. An example of a legitimate re-use of the residue
would be where the residue remains in the container and the container is used to hold
the same commercial chemical product or manufacturing chemical intermediate it
previously held. An example of the discard of the residue would be where the drum is
sent to a drum reconditioner who reconditions the drum but discards the residue.]

(d)    Any residue or contaminated soil, water or other debris resulting from the cleanup of a spill into or on any land or water of any commercial chemical product or manufacturing chemical intermediate having the generic name listed in paragraph (e) or (f) of this section, or any residue or contaminated soil, water or other debris resulting from the cleanup off a spill, into on any land or water, of any off-specification commercial chemical product or manufacturing chemical intermediate having the generic name listed in listed in paragraph (e) or (f) of this section.

[Comment: The phrase "commercial chemical product or manufacturing chemical intermediate having the generic name listed in ..." refers to a chemical substance which is manufactured or formulated for commercial or manufacturing use which consists of the commercially pure grade of the chemical, any technical grades of the chemical that are produced or marketed, and all formulations in which the chemical is the sole active ingredient. It does not refer to a material, such as a manufacturing process waste, that contains any of the substances listed in paragraph (e) or (f). Where a manufacturing process waste is deemed to be a hazardous waste because it contains a substance listed in paragraph (e) or (f), such waste will be listed in either 40 CFR 261.31 or 40 CFR 261.32 or will be identified as a hazardous waste by the characteristics set forth in Subpart C of this part.]

(e) The commercial chemical products, manufacturing chemical intermediate offspecification commercial chemical product or manufacturing chemical intermediates referred to in paragraphs (a) through (d) of this section, are identified as acute hazardous wastes (H) and are subject to be the small quantity exclusion defined in 40 CFR 261.5(e).

[Comment: For the convenience of the regulated community the primary hazardous properties of these materials have been indicated by the letters T (Toxicity), and R (Reactivity). Absence of a letter indicates that the compound only is listed for acute toxicity.]
