Solid Waste Disposal Facility - Closure and Post Closure Criteria

COURSE NO: C03-005
COURSE PROVIDER: Gilbert Gedeon, P.E.
Solid Waste Disposal Facility - Closure and Post Closure Criteria
Course Highlights

This online engineering PDH course describes EPA's closure and post-closure criteria for solid waste disposal facilities. The criteria for landfill closure focus on two central themes: (1) the need to establish low-maintenance cover systems and (2) the need to design a final cover that minimizes the infiltration of precipitation into the waste.


Critical technical issues that must be faced by the designer include the following:

  • Degree and rate of post-closure and stresses imposed on soil liner components
  • Long-term durability and survivability of cover system
  • Long-term waste decomposition and management of landfill leachate and gases
  • Environmental performance of the combined bottom liner and final cover system


Full closure and post-closure requirements apply to municipal solid waste landfill (MSWLF) units that have been receiving waste since October 9, 1993. For MSWLF units that stopped receiving wastes prior to October 9, 1993, only the final cover requirements apply.


This 3 PDH online course is applicable to owners, operators of MSWLF units, as well as engineers, designers, managers, construction workers and any other personnel involved with the closure and post-closure of municipal solid waste landfills.

Course Quiz
Once you complete your course review, you need to take a multiple-choice quiz consisting of fifteen (15) questions to earn 3 PDH credits. The quiz will be based on Chapter 6 of this EPA publication.


The minimum passing score is 70%. There is no time limit on the quiz, and you can take it multiple times until you pass at no additional cost.
