Steps
Check 40 CFR 258.28 (Liquids restrictions) - bulk/noncontainerized liquid waste is generally prohibited in MSW landfills
Note that the household-waste exception under 258.28 explicitly excludes septic waste ("household waste other than septic waste")
Recognize that leachate/gas-condensate recirculation is a separate exception requiring a composite liner and leachate collection system, and it does not cover incoming septage
If a facility does accept septage, look for it operating under a specific state variance, pretreatment/solidification process, or a documented demonstration project rather than routine acceptance
For routine disposal, direct septage to a permitted septage treatment facility, land application site, or wastewater treatment plant instead
Known gotchas
This is a common misconception - claims that "a landfill accepts septage" should be treated skeptically by default since the federal rule specifically excludes septic waste from the household-waste exception
Special demonstration projects (e.g., bioreactor landfills accepting septage under a research permit) exist but are not the general rule and require their own site-specific authorization
State solid waste programs can be stricter than the federal floor - check state rules even where a narrow federal exception theoretically exists
