 The proper disposal of chemicals is important for the protection of employee health and the environment.  The Environmental Protection Agency (EPA) enforces strict laws that govern the proper management of hazardous waste.  The EPA often levies steep fines against institutions and sometimes brings criminal charges against individuals who fail to follow proper procedures.  Government institutions like NMSU are not immune. 

Environmental Health and Safety has developed a hazardous waste manual as a guide for waste disposal.  It provides information on identification, labeling, segregation, storage, packaging, and turn-in of hazardous waste.  This guide is currently available on the EH&S  website ( 

Bottom line:  If you need assistance in determining whether or not you are producing a hazardous waste, call EH&S (646-3327) for assistance.  The following is a general list, non-inclusive, of common materials at NMSU that become hazardous wastes when they can no longer be used for their intended purpose.  These wastes must be turned into EH&S for proper disposal; they cannot be poured down the drain or placed in a dumpster.

  • Most laboratory chemicals
  • Pesticides, herbicides, rodenticides
  • Special metal batteries (Ni-Cad, Lithium, Lead-Acid, Mercury)
  • All elemental mercury and mercury compounds
  • Paint, thinners/solvents, and adhesives
  • Maintenance materials such as degreasing and lubricating agents and fuels
  • Janitorial materials such as floor waxes and strippers
  • All spill clean-up materials involving the above items

 EH&S Waste material tracking forms need to be completed and attached to each waste container. The form needs to be filled out with ALL chemical names and best estimate of the amount of each in the container, to include ALL diluents (water, alcohols, etc.). This form should be attached to the waste container as soon as waste starts to be collected and can serve as the container label.

Place waste materials in compatible containers. When possible avoid mixing waste chemicals from different waste streams. If mixing must occur, always ensure chemicals are compatible.

Waste containers must be tightly closed at all times when not in use. Store waste containers only in designated areas.

When waste containers are 75% full, package compatible wastes in boxes with packaging materials so that they will not break during transportation. Department of Transportation (DOT) approved shipping boxes are required for liquids.

Call the EH&S office (646-3327) to schedule a hazardous waste pick-up. There is no cost to the department for normal waste disposal. However, analytical fees for unlabeled or abandoned wastes may be charged to the responsible department.

Container for waste collection are available free of charge.
