Applies to establishments engaged in the disposal of refuse by processing or destruction, or in the operation of incinerators, landfills or other sites for disposal of such materials. Sanitary landfilling involves spreading typical household waste, in thin layers, compacting them to the smallest practical volume, and covering them with soil each working day in a manner that minimizes environmental impact. Sanitary landfills must have permits issued by a state regulatory program. Also included in this classification are solid waste landfills which are designed to accept construction debris such as plasterboard, cement, dirt, wood, and brush. Compactors may be used to compact the trash before it is discarded in the landfill. Incinerator operations reduce the volume of refuse with the remaining material and ashes being discarded in a landfill. Front end loaders are frequently used to feed the refuse into the incinerator. This classification includes:

• Cashiers collecting fees from customers;

• Incidental recycling or sorting operations conducted in connection with a landfill or garbage works operation by employees of an employer subject to this classification; and

• Establishments that only sort refuse. (Refuse sorting centers are distinguished from "buy back centers" in that "buy back centers" collect recyclable materials which they sell to others while refuse sorting centers collect and dispose of materials.)

This classification excludes:

• Establishments engaged in solid waste, refuse or ashes collecting, including curbside recycle services which are to be reported separately in classification 4305-18;

• Cities or towns engaged in solid waste, refuse or ashes collecting, including curbside recycle services which are to be reported separately in classification 0803;

• Counties and taxing districts engaged in operating garbage works, landfill, reduction or incineration operations which are to be reported separately in classification 1501;

• Establishments engaged in hazardous waste and toxic material processing or handling, including processing of medical or septic tank waste, drug lab or hazardous spill cleanup (excluding oil spill cleanup on land), and reprocessing or handling of low-level radioactive materials, which are to be reported separately in classification 4305-20;

• Establishments engaged in tire dumps or collection centers which are to be reported separately in classification 4305-21; and

• Buy back (recycle) center operations that include the collecting, buying from customers, sorting and the baling and sales of materials which are to be reported separately in classification 2102.

Applies to establishments engaged in collecting and removing waste from private homes, commercial establishments, industrial facilities, and other sites. Refuse may be picked up on a daily, weekly, or other regular basis. Drivers are usually assigned designated routes to collect curbside garbage or transport metal dumpsters for commercial businesses. This classification also includes the curbside collection of recyclable material when performed by employees of an employer subject to this classification. Garbage collection companies have contracts to dump refuse at landfills or local transfer stations where refuse is compacted and later transferred to a landfill. Independent owners may also contract to run the services for a county or city. This classification also includes establishments engaged in mobile paper shredding services. A truck, similar to a small moving van, is outfitted with a paper shredder. Empty bins or cans are left at establishments such as banks and law offices which need to have documents shredded, the filled containers are picked up either on a regular basis or on call, and the paper shredded on-site. The shredded paper is delivered to recyclers or other businesses who use shredded paper.

This classification excludes:

• Establishments engaged in garbage works, landfill, reduction or incineration operations which are to be reported separately in classification 4305-06;

• Counties or taxing districts engaged in garbage works, landfill, reduction or incineration operations which are to be reported separately in classification 1501;

• Cities or towns engaged in solid waste, refuse or ashes collecting, including curbside recycling services which are to be reported separately in classification 0803;

• Establishments engaged in hazardous waste and toxic material processing or handling, including processing of medical or septic tank waste, drug lab or hazardous spill cleanup (excluding oil spill cleanup on land), and reprocessing or handling of low-level radioactive materials, which are to be reported separately in classification 4305-20;

• Establishments engaged in tire dumps or collection centers which are to be reported separately in classification 4305-21; and

• Recycle ("buy-back") center operations that include the collecting, buying from customers, sorting, and the baling of materials which are to be reported separately in classification 2102.

Applies to establishments engaged in the processing or handling of hazardous/toxic materials not covered by another classification (N.O.C.), including the processing of medical or septic tank waste, drug lab or hazardous spill cleanup (excluding oil spill cleanup on land), and reprocessing or handling of low-level radioactive materials. This classification is distinguished from classification 3701-27, in that 4305-20 applies to the processing or cleanup of hazardous/toxic materials while 3701-27 includes the identifying and repackaging for disposal of such materials as drugs, pesticides, chemicals, and toners. Hazardous waste can be defined as any material that contains hazardous elements in amounts high enough to pose a significant threat to human health and the environment and therefore should be isolated. Hazardous characteristics include the ability to bioconcentrate, ignite, corrode, react with water or other materials, or show toxicity such as toxic metals including lead, cadmium and mercury; organic solvents such as benzene and trichloroethylene; and toxic materials such as asbestos.

This classification excludes:

• Establishments engaged in garbage works, landfill, reduction or incineration operations which are to be reported separately in classification 4305-06;

• Establishments engaged in solid waste and refuse or ashes collecting, including curbside recycle services and mobile paper shredding operations, which are to be reported separately in classification 4305-18;

• Establishments engaged in tire dumps or collection centers which are to be reported separately in classification 4305-21;

• Soil remediation, including oil spill cleanup on land, which is to be reported separately in classification 0101;

• Asbestos abatement, all operations, which is to be reported separately in classification 0512;

• Processing of waste oils, solvents, antifreeze, paints, and other hazardous materials, which is to be reported separately in classification 3407; and

• Hazardous/toxic material repackaging for disposal, including drugs, pesticides, chemicals, and toners, which is to be reported separately in classification 3701.

Special note: See asbestos certification and training requirements at www.lni.wa.gov.

Applies to establishments engaged in operating tire dumps or collection centers. The primary source of used vehicle tires are tire retailers who remove the tires from their customers' vehicles when replacement tires are sold. Occasionally community or charitable groups will hold a fund raising event where the public can drop off their used tires for a fee. Operations include, but are not limited to, picking up and hauling the used tires to a location where the tires can be stored or manually sorted into those with enough tread to be used on the highways; those casings suitable for retreading (either of which have a resale value); and those with no resale value which are hauled to an appropriate disposal site. This classification includes drivers as well as workers involved in the sorting operations.

Applies to establishments engaged in the collecting and removing of construction site debris left by construction crews. The debris may consist of scrap lumber, metal, wire, drywall, carpet and any other materials used in the construction of residential or commercial projects. This classification also includes the collecting and removal of nonconstruction debris. This includes, but is not limited to:

• Basement debris;

• Household junk;

• Garden waste;

• Furniture; and

• Appliances.

The debris is loaded into dump trucks, utility trucks, dump trailers, or roll off dumpsters then transferred to a landfill or local transfer station.

This classification excludes:

• Establishments engaged in residential or commercial construction that remove and haul their own debris which is to be reported in the construction classification applicable to the work being performed;

• Establishments engaged in garbage works, landfill reduction or incineration operations which are to be reported separately in classification 4305-06;
