Solid Waste Facilities: Landfill Gas

Tools and Resources

The following tools and resources are available to LEAs on issues related to landfill gas.

Gas Monitoring Equipment

The principal constituent of interest in monitoring landfill gas is methane. Combustible gas monitoring instruments should be able to detect methane at levels between 0-100 percent by volume in air while being suitably accurate in the range of 0-5 percent by volume in air.

Gas monitoring instruments should be appropriately calibrated and maintained in good operating condition.

There are several instruments which CalRecycle staff currently use to monitor landfill gas:*

  • Landtech (GEM 2000)
  • GSM (GMI Gasurveyor 442R)
  • Scott (Scout)

It is very important that the person using the monitoring instrument receive adequate training prior to its use.

Equipment Loan Program

CalRecycle developed the LEA equipment loan program to support LEA equipment needs. The program is intended to support LEAs whose financial or technical resources limit their ability to obtain and operate instrumentation and other technical and scientific equipment. The equipment loan program is available to all LEAs certified or partially certified by CalRecycle.

The program provides support through:

  • Loaning air monitoring instruments and equipment.
  • Providing technical support and training assistance for all loaned items.
  • Repairing and calibrating of LEA-owned equipment.

Field Staff Health and Safety Program

CalRecycle's Health and Safety Manual is one component of CalRecycle's overall Health and Safety Program. The program has been developed to comply with state and federal laws and regulations designed to protect employees' from toxic, hazardous or infectious materials, and physical hazards they may be exposed to in the work environment.

The Field Health and Safety Program identifies, evaluates, and controls health and safety hazards in the field for the purpose of CalRecycle employee protection, and addresses, as appropriate, site analysis, engineering controls, exposure limits, and waste handling procedures for field work. The Field Health and Safety Procedures are intended for use by field staff to provide them with health and safety guidance when performing field activities. Appendix 2 includes information on training required or recommended for and instrumentation to be taken into the field by different field staff designations (referred to as tier 0, tier 1 or tier 2).
