RCRA Hazardous Waste Number

K174

Wastewater treatment sludges from the production of ethylene dichloride or vinyl chloride monomer (including sludges that result from commingled ethylene dichloride or vinyl chloride monomer wastewater and other wastewater), unless the sludges meet the following conditions: (i) they are disposed of in a subtitle C or non-hazardous landfill licensed or permitted by the state or federal government; (ii) they are not otherwise placed on the land prior to final disposal; and (iii) the generator maintains documentation demonstrating that the waste was either disposed of in an on-site landfill or consigned to a transporter or disposal facility that provided a written commitment to dispose of the waste in an off-site landfill. Respondents in any action brought to enforce the requirements of subtitle C must, upon a showing by the government that the respondent managed wastewater treatment sludges from the production of vinyl chloride monomer or ethylene dichloride, demonstrate that they meet the terms of the exclusion set forth above. In doing so, they must provide appropriate documentation (e.g., contracts between the generator and the landfill owner/operator, invoices documenting delivery of waste to landfill, etc.) that the terms of the exclusion were met

Classification

See the full K list

Source-specific wastes from 13 named industries, including petroleum refining, wood preservation, pesticide manufacturing and iron and steel production. Each K code names both the industry and the exact process residue.

How K174 is handled

01

K codes apply only to the named industry and the named process residue.

02

Many K wastes have established recovery paths inside their industry (e.g. metals reclamation from refinery and steel residues).

03

Land disposal restrictions (40 CFR Part 268) set treatment standards before disposal.

Where can a K174 stream go?

Recognized recovery routes for this waste family, ranked by typical recovery tier. Which route fits depends on your specific stream — composition, volume and region.

In-process reclamation

Medium recovery

Process residues that still carry recoverable product or feedstock value can be reclaimed — processed to recover a usable material or regenerated for reuse — inside or outside the generating industry.

40 CFR 261.1(c)(4) — reclamation

Fuel blending & energy recovery

Medium recovery

Organic-bearing streams with usable fuel value can be blended and burned for energy recovery in permitted boilers and industrial furnaces instead of being incinerated as pure disposal.

40 CFR Part 266 Subpart H — burning for energy recovery

Treatment to LDR standard, then disposal

Low recovery

Where no recovery route fits the stream, land disposal restriction treatment standards define the required treatment before landfill — the compliance floor, not a recovery outcome.

40 CFR 268.40 — LDR treatment standards

These are the typical routes for the K list. Your stream's actual options depend on its composition and where it sits.
