[RCRA waste code finder](https://complyonsite.com/tools/rcra-waste-codes) # U154 RCRA waste code Flammable wood alcohol used as a solvent & fuel. > U154 RCRA waste code. Ignitable U-listed hazardous waste for unused methanol, a flammable alcohol used as a solvent, antifreeze & fuel. > Web page: https://complyonsite.com/tools/rcra-waste-codes?code=u154 - Free, no account - Based on 40 CFR 261.33 and EPA guidance - Nothing is stored ## Is U154 hazardous waste? **Yes, when the listing applies.** U154 covers unused methanol that is thrown away, including off-specification product and qualifying residues. It is a U-listed waste, not an acute P-listed one, so the listing depends on the product and how it is discarded, not on a TCLP result alone. The listing rests only on ignitability, corrosivity or reactivity. Under 261.3(g) it stops applying when the waste shows no hazardous waste characteristic. Another listing can still apply, and land disposal restrictions can continue. When it applies, U154 is nonacute hazardous waste. On a required [hazardous waste manifest](https://complyonsite.com/tools/hazardous-waste-manifest), put U154 in Item 13. For [VSQG exemptions and empty-container rules](https://complyonsite.com/tools/rcra-waste-codes?list=routes) and [pharmaceutical containers](https://complyonsite.com/tools/rcra-waste-codes?waste=pharmaceuticals), follow the linked guides. ## What does U154 cover? This covers unused methanol thrown away pure or technical grade, or in a formulation where it is the only active ingredient. Off-specification batches, residues in non-empty containers and spill cleanup residues of those products count too. Inactive ingredients don't stop it being the only active ingredient. - **CAS**: 67-56-1 - **Table entries**: Methanol (I) and Methyl alcohol (I) - **Hazard codes in the record**: I (ignitable) - **Rule**: [40 CFR 261.33(f)](https://www.ecfr.gov/current/title-40/chapter-I/subchapter-I/part-261/section-261.33) ## Is methanol waste always U154? | Code | When it fits | | --- | --- | | U154 | The unused chemical is thrown away, pure or technical grade or as the sole active ingredient. Qualifying product residues count too. | | [F003](https://complyonsite.com/tools/rcra-waste-codes?code=f003) | It is spent after solvent use, alone or blended only with F003 solvents before use. Recovery still bottoms count too. | | [F001–F005](https://complyonsite.com/tools/rcra-waste-codes?list=spent-solvents) | Before use, the blend held an F003 solvent plus at least 10% by volume of total F001, F002, F004 or F005 solvents. | | Characteristic waste (D001–D043) | A used chemical or a different formulation meets a hazardous waste characteristic. Any process listings that apply need assessing too. | A listed unused product can also exhibit a characteristic, so both rows can apply. Having this chemical in a manufacturing waste doesn't make the waste U154. What counts is the waste’s origin, formulation and use history. Mixing listed waste with solid waste, or treating it, generally doesn't remove the listing. That takes an applicable exclusion, exception or approved delisting. Using the chemical as an ingredient or reactant doesn't by itself make it a spent F-listed solvent. Each listing has its own before-use blend conditions. ## Which wastes take U154? | Waste | When it’s U154 | | --- | --- | | Unused methanol | The discarded commercial product is pure or technical-grade methanol, or has methanol as its sole active ingredient | ## Which codes sit beside U154? | Code | What it is | | --- | --- | | [U150](https://complyonsite.com/tools/rcra-waste-codes?code=u150) | Melphalan — a chemotherapy drug | | [U151](https://complyonsite.com/tools/rcra-waste-codes?code=u151) | Mercury | | [U152](https://complyonsite.com/tools/rcra-waste-codes?code=u152) | Methacrylonitrile | | [U153](https://complyonsite.com/tools/rcra-waste-codes?code=u153) | Methanethiol | | [U155](https://complyonsite.com/tools/rcra-waste-codes?code=u155) | Methapyrilene | | [U156](https://complyonsite.com/tools/rcra-waste-codes?code=u156) | Methyl chlorocarbonate | | [U157](https://complyonsite.com/tools/rcra-waste-codes?code=u157) | 3-Methylcholanthrene | | [U158](https://complyonsite.com/tools/rcra-waste-codes?code=u158) | 4,4′-Methylenebis(2-chloroaniline) | ### Sources - [40 CFR 261.33 — Discarded commercial chemical products, off-specification species, container residues, and spill residues thereof](https://www.ecfr.gov/current/title-40/chapter-I/subchapter-I/part-261/section-261.33) - [40 CFR 261.3 — Definition of hazardous waste](https://www.ecfr.gov/current/title-40/chapter-I/subchapter-I/part-261/section-261.3) - [40 CFR 261.7 — Residues of hazardous waste in empty containers](https://www.ecfr.gov/current/title-40/chapter-I/subchapter-I/part-261/section-261.7) - [40 CFR 260.10 — Definitions](https://www.ecfr.gov/current/title-40/chapter-I/subchapter-I/part-260/section-260.10) - [40 CFR 262.14 — Conditions for exemption for a very small quantity generator](https://www.ecfr.gov/current/title-40/chapter-I/subchapter-I/part-262/section-262.14) - [40 CFR 262.20 — General requirements](https://www.ecfr.gov/current/title-40/chapter-I/subchapter-I/part-262/section-262.20) - [40 CFR 266.507 — Residues of hazardous waste pharmaceuticals in empty containers](https://www.ecfr.gov/current/title-40/chapter-I/subchapter-I/part-266/section-266.507) - [Hazardous Waste Manifest Instructions](https://www.epa.gov/sites/default/files/2020-04/documents/manifest_instructions_web.pdf) - [40 CFR 261.31 — Hazardous wastes from non-specific sources](https://www.ecfr.gov/current/title-40/chapter-I/subchapter-I/part-261/section-261.31)
