Understanding Landfill Gas Standards for Active Sites

This one-day class was entirely classroom based and covered the new landfill gas (LFG) standards for active sites through lecture, real world and class problems.

Class Objectives

  • Understanding how the new standards apply to active landfills with existing LFG monitoring probes/wells
  • Familiarize participants with the requirements for complying with LFG monitoring systems
  • Discuss the Board’s recent studies evaluating the functionality of monitoring probes/wells


This training was attended by 164 staff from local enforcement agencies, solid waste facilities and the CIWMB.

Landfill Gas Monitoring and Control Systems at Active Landfills FAQs: This FAQ, previously published in June 2008, was revised on July 28, 2008 to include additional information about enforcement as well as new information on closed site requirements and a related Board agenda item for August 2008. This FAQ was further revised after new regulations which adjust compliance deadlines and specify submittal and implementation timeframes became effective on February 18, 2009. Provides answers to frequently asked questions (FAQ) by stakeholders regarding the new landfill gas monitoring regulations which now include the more detailed requirements currently applicable to closed disposal sites. Answers discuss the requirements, submittal and approval process, exemptions to the regulations or alternatives to the standards, and required documents.

Monitoring Program Plan Review Approach. Current CIWMB regulations require operators of active landfills to submit landfill gas program plans that demonstrate compliance with landfill gas monitoring criteria to the enforcement agency (EA) and CIWMB for EA review and approval and CIWMB review and concurrence. This page describes the procedures for plan submittal and review and clarifies exemptions for non-municipal solid waste landfills.

Final Best Management Practices (BMP) for Landfill Gas Monitoring Well/Probe Design and Construction. These BMPs were adapted from the SCS Engineers report on Landfill Gas Monitoring Well Functionality at 20 California Landfills. The Board accepted the SCS report and recommendations. The BMPs are intended to provide operators, consultants and LEAs the benefit of the study's findings and recommendations when designing, reviewing, installing or replacing required landfill gas (LFG) monitoring wells/probes. Stakeholder comments, along with those from a Technical Advisory Group, were incorporated by CIWMB staff to finalize the BMPs.

Landfill Gas Control and Monitoring Webpage. A comprehensive resource of information on landfill gas monitoring and control for LEAs and facility operators.

Regulations: Excerpts of Title 27, California Code of Regulations, Division 2, Chapter 3, Article 6 that apply to landfill gas monitoring and control at active disposal sites.
