Hazardous Waste

Hazardous Waste

Facilities regulated under the hazardous waste program will be classified into one of the following categories based on the type and volume of hazardous waste generated onsite. The classification will determine the requirements that the facility shall be expected to adhere to. The classification levels and accumulation time limits are listed below; all other requirements can be found in California Code of Regulations, Title 22.

Small Quantity Generators (SQG)

SQGs are those facilities that generate less than 1,000 Kg in any calendar month. SQGs may generate up to 1 Kg of acutely hazardous waste per month. Facilities that are Small Quantity Generators may store hazardous waste onsite for up to 180 days.

Large Quantity Generators (LQG)

LQGs are those that generate more than 1,000 Kg of hazardous waste, or more than 1 Kg of acutely hazardous waste, within a calendar month. Facilities that are Large Quantity Generators may store waste onsite for up to 90 days.

Hazardous wastes must be stored in a way to prevent accidental discharge. During an inspection you will be evaluated against requirements found in California Code of Regulations and California Health and Safety Code pertaining to the storage of hazardous wastes. Generally speaking, proper storage includes all of the following:

  • Waste stored in a way that minimizes its possibility of fire, explosion, or release
  • Maximum allowable accumulation time limits have been followed. Storage times vary based upon the quantity of waste generated. See the preceding section regarding facility classification for time limits.
  • Incompatible waste streams shall be kept separate
  • Containers must be appropriate and compatible with the type of waste being stored in them
  • Containers must be properly labeled with the words “Hazardous waste,” the name and address of the generator, the composition and physical state of the waste, hazardous properties of the waste, and the accumulation start date
  • Containers must be in good condition (Eg. no cracks, holes, or dents that could potentially decrease structural integrity)
  • Containers cannot be leaking
  • Containers shall be stored closed, except when adding or removing wastes
  • Ignitable or reactive wastes must be stored a minimum of 50 feet from the property line. (Note: this requirement only applies to LQGs.)

Universal Waste is hazardous waste that has been given relaxed standards for generators for the purposes of accumulating and transporting these waste streams until they reach a point where they are properly disposed of or recycled. Following Universal Waste requirements can sometimes benefit a hazardous waste generator as these wastes have a longer accumulation time before proper disposal is required, or can be turned in by an exchange or take-back program, including by self-transporting the waste to a proper Destination Facility. Only the below listed wastes are designated as Universal Waste:

  • Electronic devices (e.g. televisions, cell phones, computer CPUs, portable DVD players, computer monitors, etc.)
  • Batteries (e.g. most household type batteries, including rechargeable nickel-cadmium, silver button, mercury, and alkaline batteries)
  • Electric lamps (e.g. fluorescent tubes and bulbs, high intensity discharge lamps, sodium vapor lamps, etc.)
  • Mercury containing equipment (e.g. thermostats, mercury switches, thermometers, pressure or vacuum gauges, dental amalgams, dilators and weighted tubing, mercury rubber flooring, mercury novelties, etc.)
  • CRTs (glass picture tubes removed from devices such as televisions and computer monitors)
  • CRT glass (a cathode ray tube that has been accidentally broken)
  • Non-Empty aerosol cans
