Landfill Certification Information

Certification Criteria
To be eligible for SWANA certification you must:

  • Successfully complete SWANA’s Manager of Landfill Operations (MOLO) Examination.
  • Meet SWANA’s eligibility requirements, as determined by completion of a Certification Application.

If you would like to apply for certification as a Certified Landfill Manager, Landfill Inspector, or Landfill Technical Associate, you must complete a Certification Application. The State of Washington accepts all three certification levels as suitable for meeting the requirements of landfill operator certification. A Certification application will be available at the class. Applications are available prior to the exam by calling the Certification Coordinator at 301-585-2898, ext. 239, or online at http://www.swana.org and click on the Forms tab on the top of the page.

If you would like your application reviewed for certification eligibility prior to the course, please complete and fax to 301-589-7068 at least 30 days prior to the course date, and indicate “pre-course approval request” across top of the application. Please bring the original application with you to the testing site.

To be eligible for certification as a Certified Landfill Manager an individual must demonstrate that:

  • He or she is responsible for the daily on-site management of a site and for assuring that the landfill complies with its design and permit conditions, and
  • He or she has at least two years experience as a landfill manager and five years in the MSW management field (may be cumulative).

To be eligible for certification as a Certified Landfill Inspector an individual must demonstrate that:

  • He or she is responsible for assuring that the landfills under his or her jurisdiction comply with local, county and/or state permit conditions, and
  • He or she has at least two years experience as a landfill inspector and five years in MSW (may be cumulative).

To be eligible for certification as a Certified Landfill Technical Associate* an individual must demonstrate that:

  • He or she is involved in the operation, planning design or implementation of a MSW landfill but does not qualify as a Certified Landfill Manager or Inspector.

*NOTE: This includes landfill managers and inspectors with less than two years managerial experience and/or five years in MSW. If certified as a Landfill Technical Associate, once required experience is achieved, a change to Certified Landfill Manager or Landfill Inspector may be requested. Certification must be current. The State of Washington accepts the Technical Associate Certification as meeting the Washington Certified Landfill Operator/Inspector requirement.

For those interested in being SWANA Certified as a Landfill Manager, Landfill Inspector or Landfill Technical Associate, there is a mandatory three hour written examination. (Not required for currently certified individuals attending the course for recertification only).

Certification eligible candidates who pass the written examination will receive their certificates as a Landfill Manager, Landfill Inspector or Landfill Technical Associate approximately two months following the course. Individuals who were not deemed certification eligible, but passed the written examination, will receive a letter which states those facts. These individuals can be retroactively SWANA Certified if they meet the eligibility requirements within one year. All students will receive a Certification of Participation.

The Certification offered by SWANA is voluntary. SWANA does not endorse or guarantee the quality of any work or conduct of an applicant who has been certified.
