Waste codes
D011: Silver
The toxicity characteristic code for silver. Regulatory level 5.0 mg/L by TCLP.
D011 is the RCRA waste code for waste that fails the toxicity characteristic for silver. A waste carries D011 when the Toxicity Characteristic Leaching Procedure extract contains 5.0 mg/L or more of silver.
Source: 40 CFR 261.24, Table 1Where D011 waste comes from
The streams that most often carry D011 in Southeast industry:
- Photographic and radiographic film processing
- Mirror and glass silvering
- Electroplating
- Electronics and brazing alloys
- Jewelry manufacturing
Photographic fixer is frequently recoverable at a net gain to the generator.
If you generate a silver bearing stream
The practical question is rarely whether silver is present. It is whether enough of it leaches out under the TCLP to cross 5.0 mg/L. Two plants running the same process can land on opposite sides of that line depending on the matrix the waste sits in, so the determination is made per stream rather than per industry.
That matters commercially as well as legally. A stream that passes is managed as non-hazardous at a fraction of the cost, and a stream that fails carries D011 from the moment it is generated, not from the moment it is tested. Where the result sits close to the threshold, it is worth retesting when the process changes.
If you are working with photographic and radiographic film processing and have not characterized the waste, that is the place to start. Send what you have and a Certified Hazardous Materials Manager will tell you whether testing is needed or whether process knowledge already settles it.
How the determination is made
A generator must determine whether a waste is hazardous under 40 CFR 262.11. For D011 that means either testing by TCLP or applying knowledge of the process.
- TCLP extraction under SW-846 Method 1311, analyzed for silver
- Regulatory level for comparison: 5.0 mg/L
- Process knowledge is acceptable where the input materials and process are documented
- Testing settles the question. Guessing at a code is how a load gets rejected
- The determination and its basis are retained for three years under 40 CFR 262.40
How D011 waste is treated
Electrolytic or chemical recovery. Silver is usually worth reclaiming rather than disposing.

What is the regulatory level for D011?
5.0 mg/L of silver in the TCLP extract. At or above that concentration the waste carries D011 and is regulated as hazardous from the point of generation. The full table is at 40 CFR 261.24.
Does total silver content decide whether my waste is D011?
No. The toxicity characteristic is based on what leaches out under the TCLP, not on total concentration. A waste can hold a high total concentration and still pass, and the reverse is possible where the matrix releases readily.
Can D011 waste go straight to landfill?
Not untreated. Land disposal restrictions at 40 CFR Part 268 require the waste to meet a treatment standard before land disposal, and a land disposal restriction notification travels with every shipment.
Is D011 the only code my waste carries?
Often not. A stream can fail more than one characteristic and can also be listed. Every applicable code goes on the manifest, and the most stringent treatment standard governs how the waste is handled.
Who decides my waste is D011?
You do. The duty to determine sits with the generator under 40 CFR 262.11, not with the transporter or the receiving facility. Greer will characterize the stream and assign codes, but the determination remains yours to make and to document.
