Recirculated leachate application rate (in inches/year) is the total volume of leachate recirculated from company records or engineering estimates and applied to the landfill divided by the area of the portion of the landfill containing waste [with appropriate unit conversions].\nDry climate = precipitation plus recirculated leachate less than 20 inches/year;\nModerate climate = precipitation plus recirculated leachate from 20 to 40 inches/year (inclusive);\nWet climate = precipitation plus recirculated leachate greater than 40 inches/year.\nAlternatively, landfills that use leachate recirculation can elect to use the k value for wet climate rather than calculating the recirculated leachate rate.\nb Kraft Recovery Wastes include green liquor dregs, slaker grits, and lime mud, which may also be referred to collectively as causticizing or recausticizing wastes.\nc A facility that can segregate out pulp and paper industry wastewater sludge must apply the 0.12 DOC value to that portion of the sludge.","path":["Title 40—Protection of Environment","CHAPTER I—ENVIRONMENTAL PROTECTION AGENCY","SUBCHAPTER C—AIR PROGRAMS","PART 98—MANDATORY GREENHOUSE GAS REPORTING","Subpart TT—Industrial Waste Landfills"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-40.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:04Z","sha256":"b9224935f59f060bda98b1465c54cb2a06410712b470e43e6afa16491bf7c98e","source_id":"us-cfr","stale":true,"prev":"us/40-cfr-98.468","next":"us/40-cfr-98.470"},"notice":"GroundRules: Original legal text.
