RESOURCES · RCRA 101 GUIDE
A Practical Guide for Generators
RCRA, the Resource Conservation and Recovery Act, is the federal law that governs how hazardous waste is identified, handled, transported, and disposed of in the United States. This guide walks through the core concepts every manufacturer that generates waste should understand.
It is general information, not legal advice. WTS helps manufacturers apply these rules to their specific operations.
Solid Waste vs. Hazardous Waste
Every RCRA determination starts with two questions: is the material a solid waste, and if so, is it a hazardous waste. Solid waste includes liquids, semi-solids, and contained gases, not just solids.
A solid waste is hazardous if EPA specifically lists it or if it exhibits a hazardous characteristic. Materials that are not solid wastes, such as those legitimately recycled in certain ways, fall outside the hazardous waste rules.
Assigning Hazardous Waste Codes
Hazardous wastes carry EPA waste codes that drive how they must be managed. Characteristic wastes receive D-codes for ignitability (D001), corrosivity (D002), reactivity (D003), and toxicity (D004 through D043).
Listed wastes come from four lists: F-codes from common industrial processes, K-codes from specific industries, and P- and U-codes for discarded commercial chemical products. A single stream can carry multiple codes.
Waste Characterization
Characterization is how a generator determines what a waste is and which codes apply, using process knowledge, safety data sheets, and analytical testing where needed. The generator is responsible for an accurate determination.
It drives classification, packaging, manifesting, transportation, and outlet selection. WTS handles sampling, testing, and classification first.
RCRA Exclusions
RCRA includes exclusions that remove certain materials from the definition of solid or hazardous waste, often to encourage legitimate recycling and reuse, such as commercial product substitutes and specific recycling exclusions.
Applying an exclusion correctly can lawfully keep a material out of the hazardous waste system, but it requires documentation and a demonstrated, legitimate end use. Objective, provider-agnostic guidance helps here, because the goal is the right outcome, not a default to disposal.
Land Disposal Restrictions (40 CFR 268)
Land Disposal Restrictions prohibit hazardous wastes from land disposal until they meet specific treatment standards. Generators must determine whether a waste is restricted and provide the appropriate LDR notification and certification to the receiving facility.
Getting LDR determinations and paperwork right is a common compliance pressure point.
Recordkeeping and Retention
RCRA requires generators to keep records including manifests, waste determinations, LDR notifications, biennial reports for larger generators, and training and inspection records.
Most records must be kept at least three years, longer in some cases. Organized, retrievable records make an inspection straightforward.
Common RCRA Violations
The most frequent violations are avoidable with disciplined execution:
Most trace back to characterization and documentation.
How WTS Helps
WTS turns these requirements into a program that runs cleanly: accurate characterization and coding, correct manifesting and LDR paperwork, audit-ready recordkeeping, and objective routing to legitimate outlets.
