About the Compendium

The Definition of Solid Waste Compendium serves as a user-friendly reference to
assist Environmental Protection Agency (EPA) and state staff, industrial facilities
generating and managing solid and hazardous wastes, as well as the general public, in
locating resources addressing specific regulatory issues within the federal Definition of
Solid Waste regulations. Please note that this reference is designed to be web-based;
therefore, the usefulness of the document is maximized when it is viewed on a computer
that is connected to the internet.

A frequently mentioned comment from stakeholders is the need for EPA to
improve the user-friendliness of the existing regulations. Commenters note that the
applicable Definition of Solid Waste regulations and relevant guidance materials are
difficult to locate and use. As a result, stakeholders have difficulty in understanding the
regulations and identifying solid waste. The objective of this document is to address
some of the commenters' concerns by consolidating and streamlining the Definition of
Solid Waste into a helpful reference tool that features a user-friendly format, including
references to EPA FAQs (Frequently Asked Questions), letters, memoranda, and
guidance documents that EPA has provided to the public through the years to help
stakeholders interpret the Definition of Solid Waste. This document does not change any
of the existing solid or hazardous waste requirements.

The resources referenced in the Compendium may include Federal Register (FR)
notices, documents from Resource Conservation and Recovery Act (RCRA) Online (e.g.,
RCRA Hotline Q&A's, letters, and memoranda issued by EPA), and other resources, as
well as relevant Code of Federal Regulations (CFR) language. We have attempted to
identify the relevant resources for each Compendium volume topic. However, please
note that EPA could have inadvertently overlooked a relevant document and did not
reference it. Certain available resources, such as superseded RCRA Online documents
and items that were judged to be not pertinent, have not been referenced. Most of the
referenced resources are not included or reproduced in the Compendium; instead,
hyperlinks to the resources are provided. As an exception, we have included a version of
relevant sections of the most current CFR language (as of the date on the cover of the
Compendium) that we have reformatted to make it easier to read and find citations of
interest. In addition, we also provide links to the Government Printing Office's
Electronic Code of Federal Regulations Web site (e-CFR), which is updated almost daily.

Please note that this document is also not a rulemaking in any way. As well, the
included reformatted CFR language is not a substitute for the CFR itself or the
requirements in the CFR. The Government Printing Office frequently updates the e-CFR

Web site; where appropriate, hyperlinks to the respective CFR section at the e-CFR Web
site are provided.

This reference document presents only the federal Definition of Solid Waste.

Most states are authorized to manage their own solid and hazardous waste generator
regulatory program. Therefore, states may have their own set of regulations that apply in
lieu of federal regulations, and while most state solid and hazardous waste regulations are
based on the federal requirements, some states have developed regulations more stringent
than the federal program. We direct you to the following Web site to determine if the
state regulatory program is different from the federal program:
http://www.epa.gov/epaoswer/osw/stateweb.htm.

The Definition of Solid Waste includes multiple subtopics, and is codified under
40 CFR. To help users of the Compendium more quickly identify the information they
need, and to make the Compendium more user-friendly in an electronic environment, the
Compendium has been divided into multiple volumes. These volumes are available
through EPA's Definition of Solid Waste Web site at

www.epa.gov/epaoswer/hazwaste/dsw/index.htm. Because regulations are promulgated
throughout the year, EPA intends to update the Compendium volumes periodically to
remain up-to-date with regulations relating to the Definition of Solid Waste.

About the By-Products Volume

This volume of the Compendium references resources pertaining to by-products, a
group of materials that appears as included in the Definition of Solid Waste regulations at
40 CFR 261.2(c), Table 1. The definition of "by-product" appears at 40 CFR
261.1(c)(3).

This document is organized into three main sections:

•	Subtopic View - lists subtopics for resources

•	Resources - lists resources for each subtopic

•	CFR View - CFR language we've reformatted for easy reading

The Subtopic View section lists the subtopics among the resources pertaining to the
regulation of by-products under the Definition of Solid Waste regulations. The
Resources section is comprised of a table, arranged by subtopic, that provides basic
details about and a hyperlink to each resource. The CFR View section provides
reformatted versions of the relevant CFR language. As noted previously, this reproduced
language is not a substitute for the CFR itself or the requirements in the CFR.
Additionally, the Government Printing Office frequently updates the e-CFR Web site to
which the document is linked; where appropriate, hyperlinks to the respective CFR
section at the e-CFR Web site are provided. These three main sections are cross-
referenced, where each section includes hyperlinks to the other sections. Please see the
"Navigation Tips" section for document navigation guidance.

(c) For the purposes of §§261.2 and 261.6:

[* * * Preceding part text omitted* * *]

(3) A "by-product" is a material that is not one of the primary products of a production
process and is not solely or separately produced by the production process. Examples are
process residues such as slags or distillation column bottoms. The term does not include a
co-product that is produced for the general public's use and is ordinarily used in the form
it is produced by the process.

(c) Materials are solid wastes if they are recycled—or accumulated, stored, or treated before
recycling—as specified in paragraphs (c)(1) through (4) of this section.

(1) Used in a manner constituting disposal.

(i)	Materials noted with a in Column 1 of Table 1 are solid wastes when they
are:

(A)	Applied to or placed on the land in a manner that constitutes disposal;
or

(B)	Used to produce products that are applied to or placed on the land or
are otherwise contained in products that are applied to or placed on the
land (in which cases the product itself remains a solid waste).

(ii)	However, commercial chemical products listed in §261.33 are not solid wastes
if they are applied to the land and that is their ordinary manner of use.
