About the Compendium

The Hazardous Waste Generator Regulations Compendium serves as a user-friendly reference to
assist regulators, industrial facilities generating and managing solid and hazardous wastes, and
the general public in locating resources relevant to specific regulatory topics within the federal
hazardous waste generator program.

The objective of this document is to consolidate and streamline the various resources on a topic
into a user-friendly format, including references to relevant CFR language, Federal Register (FR)
notices, documents posted on RCRA Online (i.e., guidance in the form of memoranda issued by
EPA, Q&As, and other publications), and other resources, such as Frequent Questions webpages.
The Compendium has been divided into multiple volumes that are available here:
www.epa.gov/hwgenerators/hazardous-waste-generator-regulations-compendium.

This document does not change any of the existing solid or hazardous waste requirements, nor
does it offer an exhaustive list of relevant resources, as new resources may come into being or
older ones may be relevant to a specific issue, but not included. Certain available resources, such
as superseded RCRA Online documents, have not been referenced. Rather than including or
reproducing referenced resources, this document generally provides hyperlinks to individual
resources. As an exception, the Compendium does include relevant sections of the most current
CFR regulatory language (as of the date on the cover of the Compendium). The included CFR
language has been reformatted to make it easier to read, but it is not a substitute for the official
CFR itself, or for the requirements in the CFR. The Government Printing Office frequently
updates the e-CFR website; where appropriate, hyperlinks to the respective CFR section at the e-
CFR website are provided.

Most states are authorized to administer their own RCRA Subtitle C hazardous waste program.
Therefore, states may have their own set of regulations that apply in lieu of federal regulations.
State regulations must be at least as stringent as the federal standards, but they can be more
stringent. Please visit the following website to determine if the state regulatory program is
different from the federal program: https://www.epa.gov/hwgenerators/links-hazardous-waste-
programs-and-us-state-environmental-agencies, and check with your state agency.

About the Counting Hazardous Waste and Generator Categories Volume

This volume of the Compendium lists resources and CFR language pertaining to Counting
Hazardous Waste and Generator Category requirements that are found at 40 CFR 262 Subpart A
(262.13). For more information regarding other topics that apply to facilities generating
hazardous waste, refer to other volumes of the Compendium and EPA's Hazardous Waste
Generators Webpage.

Please note that the Hazardous Waste Generator Improvements rule of 2016 created new sections
in Part 262, which contains the regulations pertaining to generators. Accordingly, some citations
in the generator requirements in older resources in this Compendium are outdated, including
references to § 261.5, § 262.34, and others. Please see the preamble to the final Hazardous Waste
Generator Improvements rule for a discussion of the reorganization of the regulations (81 FR

§ 262.13 Generator Category Determination

View Resources | Go to e-CFR | Return to: CFR Index | Resource View | Main Index

A generator must determine its generator category. A generator's category is based on the
amount of hazardous waste generated each month and may change from month to month.
This section sets forth procedures to determine whether a generator is a very small quantity
generator, a small quantity generator, or a large quantity generator for a particular month.

(a)	Generators of either acute hazardous waste or non-acute hazardous waste.

A generator who either generates acute hazardous waste or non-acute hazardous
waste in a calendar month shall determine its generator category for that month by
doing the following:

(1)	Counting the total amount of hazardous waste generated in the calendar
month;

(2)	subtracting from the total any amounts of waste exempt from counting
as described in paragraphs (c) and (d) of this section; and

(3)	Determining the resulting generator category for the hazardous waste
generated using Table 1 of this section.

(b)	Generators of both acute and non-acute hazardous wastes. A generator who
generates both acute hazardous waste and non-acute hazardous waste in the same
calendar month shall determine its generator category for that month by doing the
following:

(1)	Counting separately the total amount of acute hazardous waste and the
total amount of non-acute hazardous waste generated in the calendar month;

(2)	Subtracting from each total any amounts of waste exempt from counting
as described in paragraphs (c) and (d) of this section;

(3)	Determining separately the resulting generator categories for the
quantities of acute and non-acute hazardous waste generated using Table 1
of this section; and

(4)	Comparing the resulting generator categories from paragraph (b)(3) of
this section and applying the more stringent generator category to the
accumulation and management of both non-acute hazardous waste and
acute hazardous waste generated for that month.

(c) When making the monthly quantity-based determinations required by this part,
the generator must include all hazardous waste that it generates, except hazardous
waste that:

(1)	Is exempt from regulation under 40 CFR 261.4(c) through (f),
261.6(a)(3), 261.7(a)(1), or 261.8;

(2)	Is managed immediately upon generation only in on-site elementary
neutralization units, wastewater treatment units, or totally enclosed
treatment facilities as defined in 40 CFR 260.10;

(3)	Is recycled, without prior storage or accumulation, only in an on-site
process subject to regulation under 40 CFR 261.6(c)(2);

(4)	Is used oil managed under the requirements of 40 CFR 261.6(a)(4) and
40 CFR part 279;

(5)	Is spent lead-acid batteries managed under the requirements of 40 CFR
part 266 subpart G;

(6)	Is universal waste managed under 40 CFR 261.9 and 40 CFR part 273;

(7)	Is a hazardous waste that is an unused commercial chemical product
(listed in 40 CFR part 261 subpart D or exhibiting one or more
characteristics in 40 CFR part 261 subpart C) that is generated solely as a
result of a laboratory clean-out conducted at an eligible academic entity
pursuant to § 262.213. For purposes of this provision, the term eligible
academic entity shall have the meaning as defined in § 262.200; or

(8)	Is managed as part of an episodic event in compliance with the
conditions of subpart L of this part.

17


-------
(9) Is a hazardous waste pharmaceutical, as defined in § 266.500, that is
subject to or managed in accordance with 40 CFR part 266 subpart P or is
a hazardous waste pharmaceutical that is also a Drug Enforcement
Administration controlled substance and is conditionally exempt under §
266.506.

(d)	In determining the quantity of hazardous waste generated in a calendar month,
a generator need not include:

(1)	Hazardous waste when it is removed from on-site accumulation, so long
as the hazardous waste was previously counted once;

(2)	Hazardous waste generated by on-site treatment (including reclamation)
of the generator's hazardous waste, so long as the hazardous waste that is
treated was previously counted once; and

(3)	Hazardous waste spent materials that are generated, reclaimed, and
subsequently reused on site, so long as such spent materials have been
previously counted once.

(e)	Based on the generator category as determined under this section, the generator
mustmeetthe applicable independent requirements listed in § 262.10. A generator's
category also determines which of the provisions of §§ 262.14, 262.15, 262.16 or
262.17 must be met to obtain an exemption from the storage facility permit, interim
status, and operating requirements when accumulating hazardous waste.

(f)	Mixing hazardous wastes with solid wastes -

(1) Very small quantity generator wastes.

(i)	Hazardous wastes generated by a very small quantity generator
may be mixed with solid wastes. Very small quantity generators
may mix a portion or all of [their] hazardous waste with solid waste
and remain subject to § 262.14 even though the resultant mixture
exceeds the quantity limits identified in the definition of very small
quantity generator at § 260.10 of this chapter, unless the mixture
exhibits one or more of the characteristics of hazardous waste
identified in part 261 subpart C of this chapter.

(ii)	If the resulting mixture exhibits a characteristic of hazardous
waste, this resultant mixture is a newly generated hazardous waste.
The very small quantity generator must count both the resultant
mixture amount [and] the other hazardous waste generated in the
calendar month to determine whether the total quantity exceeds the
very small quantity generator calendar month quantity limits
identified in the definition of generator categories found in § 260.10
of this chapter. If so, to remain exempt from the permitting, interim
status, and operating standards, the very small quantity generator
must meet the conditions for exemption applicable to either a small
quantity generator or a large quantity generator. The very small
quantity generator must also comply with the applicable

18


-------
independent requirements for either a small quantity generator or a
large quantity generator.

(iii) If a very small quantity generator's wastes are mixed with used
oil, the mixture is subject to 40 CFR part 279. Any material
produced from such a mixture by processing, blending, or other
treatment is also regulated under 40 CFR part 279.

(2) Small quantity generator and large quantity generator wastes.

(i)	Hazardous wastes generated by a small quantity generator or
large quantity generator may be mixed with solid waste. These
mixtures are subject to the following: the mixture rule in §§
261.3(a)(2)(iv), (b)(2) and (3), and (g)(2)(i); the prohibition of
dilution rule at § 268.3(a); the land disposal restriction requirements
of § 268.40 if a characteristic hazardous waste is mixed with a solid
waste so that it no longer exhibits the hazardous characteristic; and
the hazardous waste determination requirement at § 262.11.

(ii)	If the resulting mixture is found to be a hazardous waste, this
resultant mixture is a newly generated hazardous waste. A small
quantity generator must count both the resultant mixture amount
[and] the other hazardous waste generated in the calendar month to
determine whether the total quantity exceeds the small quantity
generator calendar monthly quantity limits identified in the
definition of generator categories found in § 260.10 of this chapter.
If so, to remain exempt from the permitting, interim status, and
operating standards, the small quantity generator must meet the
conditions for exemption applicable to a large quantity generator.
The small quantity generator must also comply with the applicable
independent requirements for a large quantity generator.

§ 262.213 Lab Clean-outs

View Resources | Go to e-CFR | Return to: CFR Index | Resource View | Main Index

(a) One time per 12 month period for each laboratory, an eligible academic entity
may opt to conduct a laboratory clean-out that is subject to all the applicable
requirements of this subpart, except that:

[...]

(2) For the purposes of on-site accumulation, an eligible academic entity is
not required to count a hazardous waste that is an unused commercial
chemical product (listed in 40 CFR part 261, subpart D or exhibiting one or
