Important Information for Reporting Year (RY) 2016
Important Information for
Reporting Year (RY) 2016
New Information for RY 2016
Please note that this version of the Toxic Chemical
Release Inventory (TRI) Reporting Forms and
Instructions document supersedes previous versions.
•	New TRI Chemical Category:
Hexabromocyclododecane (HBCD) Category
A rule was published on November 28th. 2016.
(80 FR 85440) adding an HBCD category to the
TRI list of reportable chemicals that would cover
HBCD as identified through two primary
Chemical Abstracts Service Registry Numbers
(CASRNs): 3194-55-6 (1,2,5,6,9,10-
hexabromocyclododecane) and 25637-99-4
(hexabromocyclododecane). Facilities that
manufacture, process, or otherwise use HBCD
should begin collecting release and other waste
management information on the chemical during
2017. Reporting forms will be due July 1, 2018
for HBCD if TRI chemical use and other
thresholds are met.
•	New TRI Chemical: 1-Bromopropane
A rule was published on November 23. 2015.
(80 FR 72906) adding 1-bromopropane (CAS
No. 106-94-5) to the TRI list of reportable
chemicals. Facilities that manufacture, process,
or otherwise use 1-bromopropane should have
begun collecting release and other waste
management information on the chemical during
2016. Reporting forms will be due July 1, 2017
for 1-bromopropane if TRI chemical use and
other thresholds are met.
Important RY 2016 Changes
•	Updates to TRI-MEweb for RY 2016
TRI-MEweb has been updated for RY 2016 to
improve its functionality. For a listing of these
changes for RY 2016, review the RY 2016 TRI-
MEweb Enhancements page under the Welcome
tab or visit: https://www.epa.gov/toxics-release-
inventorv-tri-program/overview-modernized-tri-
meweb.
Other Important Information for
Reporting Year 2016
Pollution Prevention. In order to promote pollution
prevention (P2), EPA has increased the prominence
and accessibility of the P2 information reported in
Sections 8.10 and 8.11 of the Form R. Some
companies reporting P2 are now highlighted in the
annual TRI National Analysis report, and all P2
entries are featured in the TRI P2 Search tool.
P2 data is also newly accessible at the corporate
level through this tool. To learn more, visit:
https://www.epa.gov/toxics-release-inventorv-tri-
program/pollution-prevention-p2-and-tri
Facilities May Submit Optional Facility Level
Information in TRI-MEweb Without Submitting
a Form R or Form A. You can use TRI-MEweb to
update location and contact information for your
facility without having to submit a TRI reporting
form. Additionally, without submitting a TRI
reporting form, you can use TRI-MEweb to indicate
that your facility will no longer be reporting to TRI
or will not be submitting a form for one or more
specific TRI-listed chemicals for the current
reporting year.
EPA's Audit Policy. If you discover your facility is
or may have been in violation of Section 313 of
EPCRA (TRI Reporting), please refer to EPA's
Policy entitled, "Incentives for Self-Policing:
Discovery, Disclosure, Correction, and Prevention of
Violations" (Audit Policy), 65 FR 19618, April 11,
2000. You may qualify for having all gravity-based
penalties waived if your facility meets all nine (9)
conditions of the Audit Policy. For more information
on EPA's Audit Policy, see the Agency's website:
https: //www. epa. gov/compliance/epas-audit-policy.
EPA Enforcement Response Policy for TRI
Revisions. On September 26, 1991, EPA published
a Federal Register notice on revisions to TRI
reporting forms under EPCRA Section 313 (56 FR
48795-03). Section V of the notice refers to the
Agency's enforcement and penalties policy
regarding Form R errors.
Facilities are reminded that there is a legal obligation
to file an accurate and complete Form R report for
each chemical by July 1 each year. EPA may take
enforcement action and assess civil administrative
penalties regarding corrections to errors in Form R
reports that are not changes based on previously
unavailable information or procedures which
improve the accuracy of the data initially reported.
ii
Toxics Release Inventory Reporting Forms and Instructions

-------
Important Information for Reporting Year (RY) 2016
The kinds of errors which may result in enforcement
and in penalties include but are not limited to the
following: (1) Errors caused by not using the most
readily available information, for example, not using
monitoring data collected for compliance or other
purposes with other regulations in calculating
releases; (2) omitting a major source of emissions;
(3) a mathematical or transcription or typographical
error which seriously compromises the accuracy of
the information, and; (4) other errors which seriously
affect the utility of the data, particularly errors in
release reporting for which the facility has no
records showing the derivation of the release
calculation, and cannot provide a sufficient
explanation of the report.
EPA's Small Business Compliance Policy. If you
have 100 or fewer employees and discover that your
facility is or may have been in violation of Section
313 of EPCRA (TRI Reporting), please refer to
EPA's Small Business Compliance Policy. EPA will
eliminate or significantly reduce penalties for small
businesses that meet the conditions of the Policy,
including voluntarily discovering violations and
promptly disclosing and correcting them. This Policy
implements Section 223 of the Small Business
Regulatory Enforcement Fairness Act (SBREFA) of
1996. For more information, see the Agency's
website:
https://www.epa.gov/compliance/small-business-
compliance.
Parent Company Information. In past years, the
Agency found that many facilities report inaccurate
parent companies and/or Dun and Bradstreet
numbers in Sections 4 and 5 of the TRI reporting
forms. All facilities should verify the accuracy of
facility and parent company information (e.g., D&B
number, parent company name). Related questions
and answers are provided in Appendix F.
Please note that EPA pre-loads standardized parent
company names into TRI-MEweb that were
researched from the prior year submissions. This
step was taken to improve the accuracy of parent
company names as well as create a standard format
for the names themselves. For example, only capital
letters are used and all periods are eliminated from
the parent names. In addition, standardized
abbreviations are now used for common terms found
in parent names such as 'CO for Company' and 'INC
for Incorporated.' More detailed explanations and a
facility-by-facility list of standardized parent names
can be found at: https://www.epa.gov/toxics-release-
inventorv-tri-program/standardized-parent-companv-
names.
A.	To verify the accuracy of your facility and parent
company Dun and Bradstreet number and name,
as required in Section 5 of both Form R and
Form A, go to:
https://www.dnb.com/product/dlw/form cc4.htm
or call 1-888-814-1435 to verify your
information. Callers to the toll free phone
number should understand that the Dun and
Bradstreet support representatives will need to
verify that callers requesting the D&B numbers
are agents of the business. Dun and Bradstreet
recommends knowing basic information such as
when the business originated, officer names, and
the name, address, and phone number for the
facility.
B.	Facilities reporting to TRI should also make sure
they are providing the parent company name and
Dun and Bradstreet number as of December 31st
of the current reporting year.
Toxics Release Inventory Reporting Forms and Instructions
in

-------
General Information
A. General Information
Reporting to the Toxic Chemical Release Inventory
(i.e., Toxics Release Inventory (TRI)) is required by
Section 313 of the Emergency Planning and
Community Right to Know Act (EPCRA, or Title
III of the Superfund Amendments and
Reauthorization Act of 1986), Public Law 99 499.
The information contained in the Form R constitutes
a "report," and the submission of a report to the
appropriate authorities constitutes "reporting."
The Pollution Prevention Act, of October, 1990
(Pub. L. 101 508), added reporting requirements to
the Form R. These requirements began with
calendar year 1991 reports and affect all facilities
required to submit a Form R under Section 313 of
EPCRA.
Reporting is required to provide information to the
public on releases and other waste management of
EPCRA Section 313 chemicals in their communities
and to provide EPA with release and other waste
management information to assist the Agency in
determining the need for future regulations.
Facilities must report the quantities of routine and
accidental releases, and releases resulting from
catastrophic or other onetime events of EPCRA
Section 313 chemicals, as well as the maximum
amount of the EPCRA Section 313 chemical on-site
during the calendar year and the amount contained
in wastes managed on-site or transferred off-site.
A completed Form R or Form A must be submitted
for each EPCRA Section 313 chemical
manufactured, processed, or otherwise used at each
covered facility as described in the reporting rules in
40 Code of Federal Regulations (CFR) Part 372
(originally published February 16, 1988, in the
Federal Register and November 30, 1994, in the
Federal Register (for Form A)).
The Electronic Reporting Rule was published in the
Federal Register on August 21. 2013 (78 FR 52860)
and requires all forms to be submitted electronically.
Reports that are not submitted electronically using
TRI-MEweb will not be processed as acceptable
submissions. However, facilities submitting TRI
reports containing trade secrets will still submit their
reports to EPA on paper, not via TRI-MEweb. This
electronic reporting requirement includes late
submissions for prior reporting years, revisions, and
withdrawals.
July 1 is the TRI reporting deadline. There is a
legal obligation to file an accurate and complete
Form R report for each chemical by July 1 each
year. EPA may take enforcement action and assess
civil administrative penalties regarding corrections
to errors in Form R reports that are not changes
based on previously unavailable information or
procedures which improve the accuracy of the data
initially reported. The kinds of errors which may
result in enforcement and in penalties include but
are not limited to the following: (1) errors caused by
not using the most readily available information, for
example, not using monitoring data collected for
compliance or other purposes with other regulations
in calculating releases; (2) omitting a major source
of emissions; (3) a mathematical or transcription or
typographical error which seriously compromises
the accuracy of the information, and; (4) other errors
which seriously affect the utility of the data,
particularly errors in release reporting for which the
facility has no records showing the derivation of the
release calculation, and cannot provide a sufficient
explanation of the report.
A. 1 Who Must Report
EPCRA Section 313 requires that reports be filed by
owners and operators of facilities that meet all of the
following criteria:
•	The facility has 10 or more full-time employee
equivalents (i.e., a total of 20,000 hours or
greater; see 40 CFR 372.3);
•	The facility is included in a North American
Industry Classification System (NAICS) code
listed in Table I; and
•	The facility manufactures (defined to include
importing), processes, or otherwise uses any
EPCRA Section 313 chemical in quantities
greater than the established threshold in the
course of a calendar year. Reporting thresholds
are listed in Section B.4.
Executive Order 13693 extends these reporting
requirements to federal facilities, regardless of their
SIC or NAICS code.

A.2 How to Submit Forms
Facilities must use the TRI-MEweb application to
submit non-trade secret TRI reports. TRI-MEweb is
accessible online and assists facilities reporting TRI
data.
Some facilities prepare TRI reporting forms using
their own software. These facilities still need to load
and submit their TRI reporting forms to EPA using
TRI-MEweb via the online reporting application's
third-party load feature. More information on the
third-party load feature can be found on the TRI-
MEweb webpage: https://www.epa.gov/toxics-
release-inventorv-tri-program/tri-meweb-resources.
Facilities must submit a copy of each reporting form
sent to EPA to the state or tribe in which that facility
is located. Conveniently, TRI-MEweb will
simultaneously send a copy of each reporting form
submitted to EPA to the appropriate state or tribal
official if the state or tribe participates in the TRI
Data Exchange (TDX). (Internet submissions are
not available for trade secret claims). This
simultaneous submission satisfies a facility's legal
obligation to report to EPA and the appropriate state
or tribe. States participating m TDX are shown on
this website.
https://www.epa.gov/toxics-release-inventorv-tri-
program/tri-data-exchange.
Please be aware that if your facility does not reside
in a state or tribe participating in the TDX, just
transmitting TRI forms via the Internet does not
satisfy your state or tribal reporting requirements for
your facility. You must report to your state or tribe
separately and in the required format specified by
your state or tribe. However, if your state or tribe is
not in the TDX then TRI-MEweb can still be used
by the reporting facility to prepare and print the
proper paper TRI forms. A senior management
official must certify the submission by signing the
TRI forms. For non-TDX states and tribes,
completed TRI forms must be printed from TRI-
MEweb and mailed to the designated state or tribal
contact. Do not send forms from the TRI-MEweb
application to EPA's Data Processing Center (DPC),
except for trade secret submissions, which still must
be sent to the DPC.
Toxics Release Inventory Reporting Forms and Instructions

General Information
A.2.a. TRI-MEweb RY 2016 Version
Facilities use TRI-MEweb to fulfill their Emergency
Planning and Community Right-to-Know (EPCRA)
Section 313 and Pollution Prevention Act (PPA)
Section 6607 reporting obligations. TRI-MEweb is
an interactive, intelligent, user-friendly web-based
application tool that guides facilities through TRI
reporting. Using a series of logically ordered
questions, TRI-MEweb streamlines the analysis
needed to determine if a user must complete a Form
R Report or if they meet thresholds that allow them
to use the Form A Certification Statement for a
particular chemical.
The TRI-MEweb software provides guidance for
each data element on the TRI reporting Forms. TRI-
MEweb checks the entered data for common errors
and then prepares it for electronic transmission and
certification in the Agency's Central Data Exchange
(CDX) (see the flow diagram of the TRI-MEweb
reporting process (Figure 1)) TRI-MEweb allows
facilities to submit, revise, and withdraw TRI
reporting forms for RYs 1991 through the current
reporting year, provided the forms do not contain
trade secret information.
A.2.b. How to Begin Using the RY 2016
TRI-MEweb Reporting Tool
TRI-MEweb is accessed through EPA's Central
Data Exchange (CDX). The TRI-MEweb
application uses EPA's CDX network to transmit
and certify electronic submissions to EPA. CDX
allows facilities to submit a paperless report and
receive instant receipt confirmation of their
submission via the Internet. TRI-MEweb supports
most Web browsers; however, should you
encounter any problems in accessing CDX or TRI-
MEweb, consult the TRI-MEweb Resource
webpage. https://www.epa.gov/toxics-release-
inventorv-tri-program/tri-meweb-resources.
Two user roles involved in TRI reporting. There
are two user roles in the TRI reporting process: a
preparer role and a certifying official role. Figure 1
(Page 3) illustrates how these two roles are involved
in the TRI reporting process. The "Preparer" is the
person who prepares TRI forms for submission in
TRI-MEweb but is not authorized to certify them.
The "Certifying Official" is the person of authority
or legal representative at a facility that will be
certifying the data contained in the submitted TRI
Form R or Form A Certification Statement in TRI-
MEweb to EPA and their state or tribe. Certifying
officials may also prepare forms, but the preparer
cannot certify TRI forms that have been transmitted
to CDX. Both TRI roles require a CDX user
account with the TRI-MEweb application added to
the MyCDX profile. Step-by-step instructions for
creating CDX user accounts for new preparers or

Establishing a CDX account and getting started
in TRI-MEweb as a new preparer or certifying
official.
•	Access the CDX login web page at
https://cdx.epa.gov/. Click the Register with
CDX link to begin creating a new CDX user
account.
•	When registering with CDX, search for TRI-
MEweb when adding a Program Service to your
account.
•	Note that CDX passwords expire after 90 days,
so please be sure to provide answers to the three
security questions that you will remember.
•	All certifying officials must submit an
Electronic Signature Agreement (ESA) form to
EPA for approval before certifying and
submitting TRI forms. If you are registering as a
certifying official, then please review the
Electronic Signature Agreement section below
to learn how to become authorized to certify and
submit TRI reporting forms.
•	Users that already have a CDX account for
other EPA reporting programs and have never
reported to TRI before will only need to add
TRI-MEweb by clicking the "Manage Program"
link on their MyCDX page. This will enable
TRI reporting through their CDX account.
Linking your new CDX account to an existing
TRI facility in TRI-MEweb. If your facility has
submitted a TRI reporting form for a prior reporting
year, it will already have a TRI Facility
Identification Number (TRIFID) assigned to it. You
should not create a new TRIFID for your facility if
the facility has previously submitted a TRI reporting
form.
In TRI-MEweb, you can also load information about
an existing TRI facility by providing the technical
contact information and TRIFID used on a report
during the prior reporting year. Or, you can enter a
6-digit access key for your facility. The person who
previously prepared or certified forms for your
facility can use TRI-MEweb to send the access key
Toxics Release Inventory Reporting Forms and Instructions

via email to allow a preparer or certifying official
connect to an existing facility. You can also contact
the CDX Help Desk at (888) 890-1995 to obtain an
access key.
A.2.c. Electronic Signature Agreement
An Electronic Signature Agreement (ESA) is a
statement that declares that the person electronically
signing a document (i.e., a reporting form)
understands the electronic signature is as legally
binding as a handwritten signature. EPA requires a
certifying official to have a signed ESA on record
before the certifying official can certify and submit
a TRI form created in TRI-MEweb. Returning
certifying officials since RY 2013 will likely have
an ESA signed on record and will only need to
navigate to the "Forms" tab and then to the
"Pending Forms" subtab in TRI-MEweb to find
any pending submission(s) that is ready to be
certified.
ESAs are created when the certifying official creates
a new CDX user account with a certifying official
role within CDX. Currently, there are two ways to
obtain an ESA approval from EPA.
Option 1 - LexisNexis real-time ESA approval.
A new certifying official may use a third-party
identity verification vendor to obtain an ESA
electronically. The certifying official will need to
voluntarily provide personal identifying information
to the third-party vendor (EPA does not collect any
personal information from our users) to authenticate
his or her identity. The most significant benefit
gained from using this third-party identify
verification is that users will no longer need to wait
up to 5 business days for EPA to approve an ESA. If
the certifying official does not wish to provide
personal information to a third-party vendor, he or
she should submit a paper ESA form instead well
ahead of the July 1 reporting deadline.
A significant advantage of this real-time method,
besides obtaining immediate ESA approval, is that
the real-time approval is applicable to multiple CDX
system flows. Programs like eTSCA and Risk
Management Plan (RMP e Submit) will be able to
share the security credentials offered by the CDX
ESA obtained under TRI. To obtain this real-time
approval, the certifying official must provide
personal identity authentication information such as
name, address, etc. Please note that EPA does not
collect any personal information from our users. The
use of these third-party verification and
identification widgets is common in banking
systems.
Option 2 - Paper ESA form. A printable ESA form
can be generated during the CDX registration
process. The ESA form must be signed and mailed
to EPA's Data Processing Center (DPC in Figure 1)
for approval before the certifying official can begin
to certify any TRI forms transmitted by the preparer
to CDX using TRI-MEweb. Hard copy ESA
approval may take up to five business days, so
please plan accordingly or consider option one,
LexisNexis. TRI-MEweb is updated when the ESA
is approved.
Paper ESAs can be mailed to the address below:
Attention: TRI ESA Approval Request
TRI Reporting Center
P.O. Box 10163
Fairfax, VA 22038
The hard copy ESA approval process requires
the printing, completion, and mailing of an
electronic signature agreement form. Please
allow adequate time for the mailing and
processing of this form, which is estimated to
take a minimum of five (5) business days.
Certifying officials who do not have a signed ESA,
electronic or hard copy, will not be able to certify
forms in TRI-MEweb. It is recommended that
certifying officials complete their ESA well in
advance of the reporting deadline.
Accidental deletion of ESA in TRI-MEweb. The
TRI-MEweb application also has the capability to
manage user profiles (previously authorized
preparers or certifying officials) that have been
granted access to facility accounts. This capability
includes revoking approved ESA(s) for any
certifying official(s) that has left the facility's
payroll or is no longer authorized to certify forms.
An ESA could also be accidently revoked by the
preparer. If this occurs, there is a 45-day grace
period to get the ESA reactivated by the CDX
helpdesk without having to send a paper form to
EPA for re-approval. An email notification is sent to
the affected certifying official by CDX when an
ESA has been revoked within TRI-MEweb.
TRIFID Signature Agreement. In addition to the
ESA requirement, new certifying officials must sign
a TRIFID Signature Agreement for each facility
they represent. By signing the TRIFID Signature
Agreement, certifying officials are confirming that
they are owner/operators or senior management
Toxics Release Inventory Reporting Forms and Instructions
4

-------
General Information
officials for the reporting facility and are authorized
to certify forms for that facility. Certifying officials
must complete the TRIFID Signature Agreement
only once for each facility they represent as a
certifying official. Returning certifying officials will
be ready to certify any forms for a facility account
that has a signed TRIFID Signature Agreement. A
single CDX ESA will also allow new and returning
certifying officials to represent additional facility
accounts without the need for an ESA approval for
each facility account. All newly added facility
accounts will only require a TRIFID Signature
Agreement to be signed.
To sign the TRIFID Signature Agreement form,
users must be logged into TRI-MEweb using an
account with a certifying official role and users must
have at least one facility account with an approved
ESA. Click on the "Facility Management" tab to
access the Manage TRIFID Signature Agreements
page, where a list of TRIFIDs pending signature is
displayed. Then select the check box next to the
facility's TRIFID in the "Pending Signature" table
and click "Sign Agreement" button. Review the
TRIFID Signature Agreement and click "I Agree"
button. The electronic signature widget will prompt
the certifying official to enter their CDX password,
answer a secret question, and click "Sign" button. A
confirmation box will appear, noting the successful
signature.
ESA and TRIFID Signature Agreement Status in
TRI-MEweb. The ESA and TRIFID Signature
Agreement status of the certifying official(s)
assigned to each facility is listed under the ESA
Status column in TRI-MEweb.
•	A status of © No CDX ESA indicates that no
certifying officials are associated with the
facility.
•	A status of Sign CDX ESA indicates that
either:
o The certifying official has not signed an
ESA. The certifying official must sign a
new CDX ESA.
o The certifying official has provided a paper
copy of ESA prior to RY 2012. The
returning certifying official must
electronically sign a new CDX ESA upon
logging in to CDX for first time in RY
2014. Also note that TRIFID Signature
Agreement has also not been signed.
•	A status of Sign TRIFID Signature
Agreement indicates that the certifying official
has obtain approval of the CDX ESA, but still
needs to sign the TRIFID Signature Agreement
within the TRI-MEweb application.
•	A status of Active Certifying Official
Available indicates that your assigned
certifying official has received approval of the
ESA, signed the TRIFID Certification
Agreement, and is ready to certify any pending
forms transmitted by the preparer.

Import previous year data into current year
chemical forms. TRI-MEweb can import prior year
data (if RY 2015 data were provided by the facility
in the previous year) into each selected current year
TRI chemical form. Although it is optional,
importing data can accelerate data entry if the same
chemicals are reported to EPA each year. Importing
data into any forms that have been already started in
TRI-MEweb will result in the data being
overwritten by the imported data fields.
Error checker software in TRI-MEweb. Once
data entry has been completed or data has been
imported into TRI forms using TRI-MEweb, you
must click the "Check for Errors" button to begin
the error checking software in TRI-MEweb. Error
checking in TRI-MEweb is applicable for any forms
created or revised for RYs 2005- 2016.
Processing TRI forms for Certification. Once you
have check for errors using TRI-MEweb's Error
Checking procedures and have passed with no
detectable critical errors, you can proceed to
process your forms for certification. Processing your
forms means that your designated certifying official

form should a correction to the form be necessary. If
no corrections are needed and the certifying official
is ready to submit the form to EPA, the certifying
official can digitally sign the form and submit it. To
sign and submit a TRI reporting form the certifying
official will need to answer to a security question or
use a SMS text verification service to verify
identity. An email from CDX will confirm that the
form has been properly certified and submitted
Uncertified TRI-ME web Submissions. A facility's
registered certifying official must electronically sign
Form R and/or Form A reports via TRI-MEweb
before the submission is complete. Uncertified TRI-
MEweb electronic submissions are not considered
complete according to the reporting requirements in
EPCRA Section 313. Lack of certification will
prevent the submission from being processed.

to TRI reporting facilities.
A.2.e. Confirmation of TRI
Submission(s) to EPA
You can confirm that you have properly submitted
your TRI Form R/ and Form A Certification
Statement by the following methods:
TRI-MEweb: Confirmation of your Federal and
State/Tribal submission can be found on the
Submission History tab in the TRI-MEweb
application.
CDX Email: A CDX email is sent to the registered
email address of the certifying official, preparer and
technical contact of the reporting facility after the
form has been certified in TRI-MEweb. If you have
not received a confirmation email, verify that your
registered email address has not changed or that the
CDX email is not being diverted to another inbox by
your junk/spam email filter.
Electronic Receipt (e-Receipt). After a form is
certified and submitted it goes through additional
data quality checks. Once the form clears these
checks, which may take several days, it enters
EPA's TRI database. Once this happens, you will be
able to access an e-Receipt in TRI-MEweb by
reviewing the "Submission History" tab in TRI-
MEweb (formerly known as electronic Facility Data
Profile or eFDP).
If the facility's Technical Contact provides an email
address in the Form R/Form A Certification
Statement, they will also receive an email notifying
them when their e-Receipt has been published for
review in TRI-MEweb. Please Note: the technical
contact will typically receive this email following
the certification and submission of a form; however,
data quality checks performed after submittal of the
form could delay for several days the sending of this
e-Receipt email.
A.2.f. State and Tribal Submissions
Facilities that reside in a state or tribe participating
in the TRI Data Exchange (TDX) will have their RY
2005 - 2016 forms sent simultaneously to EPA and
their state or tribal TRI representative in electronic
format. Find which states are participating in TDX
at: https://www.epa.gov/toxics-release-inventory-tri-
program/tri-data-exchange
If the facility is in a state that is not in TDX, then
the facility must also send a copy of the report to the
state. To verify if your state is or is not in the TDX
system, go to: https://www.epa.gov/toxics-release-
inventorv-tri-program/tri-data-exchange. "State"
also includes: the District of Columbia, the
Commonwealth of Puerto Rico, Guam, American
Samoa, Marshall Islands, the U.S. Virgin Islands,
the Commonwealth of the Northern Mariana
Islands, and any other jurisdiction and Indian
country. Refer to Appendix E for the appropriate
state submission addresses.
Facilities located within a tribe's Indian country will
need to provide their three-digit Bureau of Indian
Affairs (BIA) tribal code for their Indian country
name in the "City/County/Tribe/State/ZIP code"
field on the Form R or Form A in Section 4.1. In
TRI-MEweb, these facilities should select the "My
facility is located in Indian Country" checkbox and
"Add BIA Code," which provides a searchable list
of BIA codes and corresponding Indian country
Toxics Release Inventory Reporting Forms and Instructions
6

-------
General Information
names. BIA tribal codes are also provided in Table
III.
Hard copies of TRI forms must be mailed to the
tribe's Chief Executive Officer because most tribal
entities are not members of TDX. If tribes have
entered into a cooperative agreement with states,
report submissions should be sent to the entity
designated in the cooperative agreement. Facilities
using TRI-MEweb to fulfill their federal and tribal
reporting requirements under EPCRA Section 313
will be able to print a hard copy of the TRI form to
mail to their Indian country's Chief Executive
Officer.
RYs 1991 - 2004 submissions: If a facility prepares
and submits a TRI RY 1991 through RY 2004 form
using TRI-MEweb, they must print/save a copy of
their TRI form on a disk and send it to their State or
Tribal TRI coordinator, even if State or Tribal
Country is on the TRI Data Exchange (TDX)
network. TDX is not configured to transmit pre-RY
2005 TRI forms.
A.3 Trade Secret Claims
A trade secret claim may be submitted to prevent
disclosure of the identity of an EPCRA Section 313
chemical. See Appendix G for instructions on
preparing and submitting trade secret claims. Note
that trade secret submissions must be on paper and
that TRI-MEweb does not support the preparation of
trade secret TRI reporting forms.
A.4 Recordkeeping
Sound recordkeeping practices are essential for
accurate and efficient TRI reporting. It is in the
facility's interest, as well as EPA's, to maintain
records properly. Facilities must keep a copy of
each report filed for at least three years from the
date of submission. These reports will be of use
when completing future reports.
Facilities must also maintain those documents,
calculations, worksheets, and other forms upon
which they relied to gather information for prior
reports. In the event of a problem with data elements
on a facility's Form R or Form A report, EPA may
request documentation from the facility that
supports the information reported.
EPA may conduct data quality reviews of Form R or
Form A submissions. An essential component of
this process involves reviewing a facility's records
for accuracy and completeness. EPA recommends
that facilities keep a record for those EPCRA
Section 313 chemicals for which they did not file
EPCRA Section 313 reports.
EPA also recommends keeping records of all
documentation containing your CDX account
information for your preparer(s) and certifying
official(s) that use TRI-MEweb to prepare and
certify the reporting facility's TRI Form R and/or
Form A. These CDX documents include the
Electronic Signature Agreement (ESA) and the
facility's unique 6-digit alphanumeric access key.
Records to maintain include:
•	Previous years' EPCRA Section 313 reports;
•	EPCRA Section 313 Reporting Threshold
Worksheets;
•	Engineering calculations and other notes;
•	Purchase records from suppliers;
•	Inventory data;
•	EPA (NPDES) permits and monitoring reports;
•	EPCRA Section 312 Tier II Reports;
•	Monitoring records;
•	Flowmeter data;
•	RCRA Hazardous Waste Generator's Report;
•	Pretreatment reports filed by the facility with
the local government;
•	Invoices from waste management companies;
•	Manufacturer's estimates of treatment
efficiencies;
•	RCRA manifests;
•	Process diagrams that indicate emissions and
other releases;
•	Records for those EPCRA Section 313
chemicals for which they did not file EPCRA
Section 313 reports; and
•	CDX account information including unique 6-
digit access key to pre-load facility account into
TRI-MEweb and copies of the Electronic
Signature Agreement (s) submitted to EPA for
approval.

General Information
A. 5 How to Revise, Withdraw or
Cancel TRI Data
A.5.a. Revising TRI Data
Facilities that filed a Form R and/or Form A
Certification Statement under EPCRA Section 313
may submit a request to revise a form that was
previously submitted, stored in EPA's historical
database called the Toxics Release Inventory
Processing System (TRIPS), and made available to
the public through Envirofacts and TRI Explorer.
Facilities may only revise TRI reporting forms
submitted for RY 1991 through the current reporting
year and must do so using TRI-MEweb.
Facilities may request a revision for one or more of
the following reasons:
Revision codes:
•	RR1 - New Monitoring Data
•	RR2 - New Emission Factor(s)
•	RR3 - New Chemical Concentration Data
•	RR4 - Recalculation(s)
•	RR5 - Other Reason(s)
Please note that late submissions for chemicals not
reported in a previous reporting year are not
considered revisions for that year.
Facilities are reminded that there is a legal
obligation to file an accurate and complete Form R
or Form A report for each chemical by July 1 each
year. EPA may take enforcement action and assess
civil administrative penalties regarding corrections
to errors in Form R reports that are not changes
based on previously unavailable information or
procedures which improve the accuracy of the data
initially reported. The kinds of errors which may
result in enforcement and in penalties include but
are not limited to the following: (1) Errors caused
by not using the most readily available information,
for example, not using monitoring data collected for
compliance with other regulations in calculating
releases; (2) omitting a major source of emissions;
(3) a mathematical or transcription or typographical
error which seriously compromises the accuracy of
the information, and; (4) other errors which
seriously affect the utility of the data, particularly
errors in release reporting for which the facility has
no records showing the derivation of the release
calculation, and cannot provide a sufficient
explanation of the report.
How do I revise my submission(s)?
If you plan to revise a TRI submission, send revised
report(s) to EPA and the appropriate state or tribal
agency.
Use TRI-MEweb to submit revisions to TRI
submissions. EPA will only accept revisions for RY
1991 through the current year.
If you have questions about using TRI-MEweb to
revise your Form R/A, please refer to the TRI-
MEweb Tutorials page at:
https://www.epa.gov/toxics-release-inventory-tri-
program/training.
A.5.b. Withdrawing TRI Data
Facilities that filed a Form R and/or Form A
Certification Statement under EPCRA Section 313
may submit a request to withdraw a form that was
previously submitted, stored in the Toxics Release
Inventory Processing System (TRIPS), and made
available to the public through Envirofacts and TRI
Explorer. EPA may periodically review
withdrawals.
Use TRI-MEweb to submit revisions to withdraw
TRI reporting forms submitted for RY 1991 through
the current reporting year.
Facilities may request a withdrawal for one or
several reasons, such as:
Withdrawal codes:
•	WT1 - Did not meet the reporting threshold for
manufacturing, processing, or otherwise use
•	WT2 - Did not meet the reporting threshold for
number of employees
•	WT3 - Not in a covered NAICS Code
•	W01 - Other reason(s)
How do I withdraw my submission(s)?
If you plan to withdraw a TRI submission, send
your request to EPA using TRI-MEweb -
withdrawals on paper forms will not be accepted.
Withdrawal requests for RY 2005 - 2016 forms will
be automatically submitted to states participating in
the TRI Data Exchange (TDX). Non-TDX
state/tribal facilities need to mail in hard copy forms
to their state or tribe. Keep in mind that successfully
completed withdrawal requests permanently delete
the chemical release data that was provided by the
reporting facility and processed into TRI's publicly
available database.
Toxics Release Inventory Reporting Forms and Instructions
8

-------
General Information
If the reporting facility needs to make a correction
to data submitted to EPA, you should revise the
form rather than withdraw and resubmit the form.
Use TRI-MEweb to withdraw TRI forms from RY
1991 through the current year. Withdrawals can
only be done for TRI submissions that have been
properly transmitted, certified and processed by
EPA. If you have questions about using TRI-
MEweb to withdraw your Form R/A, please refer to
the TRI-MEweb Tutorials page at:
https://www.epa.gov/toxics-release-inventorv-tri-
program/training.
A.5.c. Canceling a TRI Submission
Different situations may require a TRI-MEweb user
to cancel an electronic TRI submission. For
instance, a facility's preparer or certifying official
may determine that a draft electronic submission(s)
requires cancellation because the facility's chemical
release did not, in fact, meet the reporting thresholds
of EPCRA Section 313.
Another reason why a TRI-MEweb submission may
require cancellation is if a preparer or certifying
official has determined that a correction is needed
on a TRI form that is pending certification in CDX,
but has not yet been certified. In order to edit a TRI
form in TRI-MEweb that is pending certification to
CDX, the preparer will need to cancel the
submission with a Pending Certification status in
order to make the additional corrections in TRI-
MEweb and reprocess the original submission or
revision to be certified. EPA is considering issuing
a Notice of Non-compliance for TRI Forms that
have been transmitted to CDX but are not certified.
A preparer or a certifying official cannot cancel a
TRI form submission that has already been certified
by the certifying official. If a chemical form has a
status of Certified and Sent to EPA in TRI-MEweb
it cannot be called back to be edited or corrected. To
change or remove data that has already been
certified and submitted to EPA to be processed,
either revise or withdraw the submission.
Note: ALL chemical forms that were included in the
selected submission will be canceled.
How to Cancel a TRI Submission that has not
been Certified. If your facility decides not to
complete the certification process for any pending
electronic submission(s) transmitted to CDX by
TRI-MEweb, you should CANCEL the
submission(s) using one of the following methods:
By the Preparer: The preparer may use the TRI-
MEweb application to cancel any unwanted pending
submission(s). In TRI-MEweb, the preparer must
click the "Forms Home" subtab under the "Form"
tab, choose the Reporting Year corresponding to the
unwanted submission(s), expand the form summary
table by clicking the "+" sign, , and select the
"delete" button for the chemical form to be
cancelled from the Select a Form page. T Note:
ALL chemical forms that were included in the
selected submission will be canceled.
By the Certifying Official: The certifying official
may also cancel any unwanted TRI submission(s)
pending certification (forms that have been assigned
a certifying official). The certifying official must log
into their CDX account and click the TRI-MEweb:
TRI Made Easy -link from their MyCDX page. This
will open the Welcome page of the TRI-MEweb
application and then select the "Forms" tab and
then select the "Pending Forms" subtab. If certifying
official does not find the TRIFID for their reporting
facility with pending submissions listed, they gain
access to that facility account by entering the access
key for the facility listed in the Pending
Authentication section on the Manage Facilities
page and signing the TRIFID Signature Agreement
on the Manage TRIFIDs Signature Agreement page
and clicking the "Next" button. The electronic
signature widget will pop-up to confirm your
authorized access to the facility account. Upon
successful authentication of user identity, you may
begin the cancellation process on the Pending
Forms page. You may view the content of the
submission by clicking the "Check for Errors"
page and navigating to the Passed Forms section to
confirm that this is the correct submission to be
cancelled. Select the "Cancel" button to cancel
submission.
Can I submit a paper form if I cannot certify
forms before the July 1 deadline? Please note that
if you are not able to certify prior to the July 1
deadline, you will not be able to submit on paper.
Please ensure you execute an electronic signature
agreement (ESA) well ahead of the July 1 deadline.
If your certifying official could not certify prior to
the July 1 deadline because he or she had not
established an approved Electronic Signature
Agreement (ESA), he or she should log into CDX
once it becomes approved by EPA and certify any
pending submission(s).
If a facility could not process their ESA on time,
should their certifying official still certify
Toxics Release Inventory Reporting Forms and Instructions

-------
General Information
electronically after the July 1 deadline? Yes. If a
certifying official cannot certify prior to the July 1
deadline because they have not established an
approved ESA, they should log into CDX once it
becomes approved by EPA and certify any pending
submission(s).
A. 6 When the TRIReport Must Be
Submitted
As specified in EPCRA Section 313, the report for
any calendar year must be submitted on or before
midnight on July 1 of the following year whether
using Form R or Form A. If the reporting deadline
falls on a Saturday or Sunday, EPA will accept
forms submitted on the following Monday (i.e., the
next business day).
Any voluntary revision to a report can be submitted
anytime during the calendar year for the current or
any previous reporting year. However, voluntary
revisions for the current reporting year should be
submitted by July 31 in order to be included in that
year's TRI National Analysis.
1.7 How to Obtain the TRI Reporting
Forms
The TRI Form R, Form R Schedule 1, Form A
Certification Statement, and related guidance
documents may be obtained from EPA's GuideME
website at: https://www.epa.gov/toxics-release-
inventorv-tri-program/reporting-forms-and-
instructions. However, non-trade-secret TRI
reporting forms must be submitted to EPA using
TRl-MEweb. Paper forms are no longer processed
by EPA. Please do not send any paper forms, except
for trade secret submissions, to EPA's Data
Processing Center.

How to Determine if Your Facility Must Submit a Form R or Is Eligible to Use Form A
B. How to Determine if Your
Facility Must Submit a
Form R or Is Eligible to Use
Form A
This section will help you determine whether you
must submit an EPCRA Section 313 report (EPA
Form R or Form A Certification Statement). This
section discusses EPCRA Section 313 reporting
requirements such as the number of full-time
employees, primary NAICS code, and chemical
activity threshold quantities. The EPCRA Section
313 chemicals and chemical categories subject to
reporting are listed in Table II (also see 40 CFR
372.65). (See Figure 2 for more information.)
B.l Full-Time Employee
Determination
The number of full-time employees is dependent
only upon the total number of hours worked by all
employees and other individuals (e.g., contractors)
for the facility during the calendar year and not the
number of persons working. Therefore, a full-time
employee, for purposes of EPCRA Section 313
reporting, is defined as 2,000 work hours per year.
When making the full-time employee determination,
the facility must consider all paid vacation and sick
leave used as hours worked by each employee. In
addition, EPA interprets the hours worked by an
employee to include paid holidays. To determine the
number of full-time employees working for your
facility, add up the hours worked by all employees
during the calendar year, including contract
employees and sales and support staff working for
the facility, and divide the total by 2,000 hours. The
result is the number of full-time employees. In other
words, if the total number of hours worked by all
employees for your facility is 20,000 hours or more,
your facility meets the ten employee threshold.
Examples:
•	A facility consists of 11 employees who each
worked 1,500 hours for the facility in a calendar
year. Consequently, the total number of hours
worked by all employees for the facility during
the calendar year is 16,500 hours. The number
of full-time employees for this facility is equal
to 16,500 hours divided by 2,000 hours per full-
time employee, or 8.3 full-time employees.
Therefore, even though 11 persons worked for
this facility during the calendar year, the
number of hours worked is equivalent to 8.3
full-time employees. This facility does not meet
the employee criteria and is not subject to
EPCRA Section 313 reporting.
•	Another facility consists of six workers and
three sales staff. The six workers each worked
2,000 hours for the facility during the calendar
year. The sales staff also each worked 2,000
hours during the calendar year although they
may have been on the road half of the year. In
addition, five contract employees were hired for
a period during which each worked 400 hours
for the facility. The total number of hours is
equal to the time worked by the workers (12,000
hours), plus the time worked by the sales staff
for the facility (6,000 hours), plus the time
worked by the contract employees (2,000
hours), or 20,000 hours. Dividing the 20,000
hours by 2,000 yields 10 full-time employees.
This facility has met the full-time employee
criteria and may be subject to reporting if the
other criteria are met.

B.2 Primary NAICS Code
Determination
The facility should determine its own NAICS
code(s), based on its activities on-site using the by
conducting NAICS keyword and NAICS 2 to 6-digit
code searches on the Census Bureau website at:
http://www.census.gov/eos/www/naics/
or referring to the 2012 NAICS Definitions at:
http://www.census.gov/eos/www/naics/2012NAICS
/2012 Definition File.pdf.
For purposes of EPCRA Section 313 reporting, state
assigned codes should not be used if they differ
from codes assigned using the NAICS Manual.
The full list of 2012 NAICS codes for facilities that
must report to TRI (including exceptions and/or
limitations) if all other threshold determinations are
met can be found in Table I and also at the TRI
website at: https://www.epa.gov/toxics-release-
inventorv-tri-program/mv-facilitvs-six-digit-naics-
code-tri-covered-industry.
Beginning with Reporting Year 2006, the TRI
Program requires North American Industry
Classification System (NAICS) codes instead of
Standard Industrial Classification (SIC) codes.
NAICS codes found in Table I correspond to the
following Standard Industrial Classification (SIC)
Codes: SIC 10 (except 1011, 1081, and 1094), 12
(except 1241), 20-39, 4911 (limited to facilities that
combust coal and/or oil for the purpose of
generating electricity for distribution in commerce),
4931 (limited to facilities that combust coal and/or
oil for the purpose of generating electricity for
distribution in commerce), 4939 (limited to facilities
that combust coal and/or oil for the purpose of
generating electricity for distribution in commerce),
4953 (limited to facilities regulated under RCRA
Subtitle C, 42 U.S.C. Section 6921 et seq.), 5169,
5171, and 7389 (limited to facilities primarily
engaged in solvents recovery services on a contract
or fee basis).
A direct final rule was published in the Federal
Register on July 18, 2013 (78 FR 42875) to adopt
2012 NAICS codes for RY 2013 and subsequent
reporting years.
B.2.a. Auxiliary Facilities
Under the Standard Industrial Classification (SIC)
system, an auxiliary facility was defined as one that
supported another covered establishment's activities
(e.g., research and development laboratories,
warehouses, and storage facilities). An auxiliary
facility could assume the SIC code of another
covered establishment if its primary function was to
service that other covered establishment's
operations. The North American Industry
Classification System (NAICS), that replaces the
SIC system for TRI reporting, does not recognize
the concept of auxiliary facilities and assigns
NAICS codes to all establishments based on
economic activity. In its rulemaking, "Toxic
Chemical Release Reporting Using North American
Industry Classification System," the TRI Program
has adopted NAICS for TRI reporting and also the
NAICS treatment of former "auxiliary facilities" as
entities with their own distinct NAICS code.
B.2.b. Multi-establishment Facilities
Your facility may include multiple establishments
that have different NAICS codes. A multi-
establishment facility is a facility that consists of
two or more distinct and separate economic units. If
your facility is a multi-establishment facility,
calculate the value added of the products produced,
shipped, or services provided from each
establishment within the facility and then use the
following rule to determine if your facility meets the
NAICS code criterion:
•	If the total value added of the products
produced, shipped, or services provided at
establishments with covered NAICS codes is
greater than 50 percent of the value added of the
entire facility's products and services, the entire
facility meets the NAICS code criterion.
•	If any one establishment with a covered NAICS
code has a value added of services or products
shipped or produced that is greater than any
other establishment within the facility (40 CFR
Section 372.22(b)(3)) the facility also meets the
NAICS code criterion (see Figure 3).

Figure 3. Example of a Multi-Establishment Facility
The value added of production or service
attributable to a particular establishment may be
isolated by subtracting the product value obtained
from other establishments within the same facility
from the total product or service value of the
facility. This procedure eliminates the potential for
"double counting" production and services in
situations where establishments are engaged in
sequential production or service activities at a single
facility.
Examples include:
• A facility in coating, engraving and allied
services has two establishments. The first
establishment, a general automotive repair
service, is in NAICS code 811113 (SIC 7537),
which is not a covered NAICS code. However,
the second establishment, a metal paint shop is
in NAICS code 332812 (SIC 3479, which is a
covered NAICS code). The metal paint shop
paints the parts received from general
automotive repair service. The facility
determines the product is worth $500/unit as
received from the general automotive repair
service (in non-covered NAICS code 811113)
and the value of the product is $1500/unit after
processing by the metal paint shop (in covered
NAICS code 332812). The value added by the
metal paint shop is obtained by subtracting the
value of the products from the general
automotive repair service from that of the value
of the products of the metal paint shop. (In this
example, the value added = $l,500/unit -
$500/unit = $l,000/unit.) The value added
($l,000/unit) by the establishment in NAICS
code 332812 is more than 50 percent of the
product value. Therefore, the facility's primary
NAICS code is 332812, which is a covered
NAICS code.
• A food processing establishment in a facility
processes crops grown at the facility in a
separate establishment. To determine the value
added of the products of each establishment the
facility could first determine the value of the
crops grown at the agricultural establishment,
and then calculate the contribution of the food
processing establishment by subtracting the crop
value from the total value of the product
shipped from the processing establishment
(value of product shipped from processing -
crop value = value of processing establishment).

How to Determine if Your Facility Must Submit a Form R or Is Eligible to Use Form A
A covered multi-establishment facility must make
EPCRA Section 313 chemical threshold
determinations and, if required, report all relevant
information about releases and other waste
management activities, and source reduction
activities associated with an EPCRA Section 313
chemical for the entire facility, even from
establishments that are not in covered NAICS codes.
EPA realizes, however, that certain establishments
in a multi-establishment facility can be, for all
practical purposes, separate and distinct business
units. Therefore, while threshold determinations
must be made for the entire facility, individual
establishments which compose the entire facility
may report their individual releases and other waste
management activities separately. However, the
total releases and other waste management
quantities for the entire facility must be represented
by the sum of the releases and other quantities
managed as waste reported by each of the separate
establishments.
B.2.c. Property Owners
You are not required to report if you merely own
real estate on which a facility covered by this rule is
located; that is, you have no other business interest
in the operation of that facility (e.g., your company
owns an industrial park). The operator of that
facility, however, is subject to reporting
requirements.
B.2.d. Federal Facilities
In 1993, pursuant to an Executive Order (EO),
federal facilities began complying with Section 313
of EPCRA regardless of their primary North
American Industry Classification System (NAICS)
code. Subsequent EOs reinforced this requirement,
with EO 13693 being the most recent EO on this
requirement. As a result, all federal facilities,
regardless of NAICS code, must report if they meet
the employment and chemical activity thresholds.
See Appendix A for additional information on
Federal Facility reporting requirements.
B.3 Activity Determination
B.3.a. Definitions of Manufacture,
Process, and Otherwise Use
Manufacture: The term "manufacture" means to
produce, prepare, compound, or import an EPCRA
Section 313 chemical. (See Part II, Section 3.1 of
these instructions for further clarification.)
Import is defined as causing the EPCRA Section
313 chemical to be imported into the customs
territory of the United States. If you order an
EPCRA Section 313 chemical (or a mixture
containing the chemical) from a foreign supplier,
then you have imported the chemical when that
shipment arrives at your facility directly from a
source outside of the United States. By ordering the
chemical, you have caused it to be imported, even
though you may have used an import brokerage firm
as an agent to obtain the EPCRA Section 313
chemical.
Do Not Overlook Coincidental Manufacture
The term "manufacture" also includes coincidental
production of an EPCRA Section 313 chemical
(e.g., as a byproduct or impurity) as a result of the
manufacture, processing, otherwise use or disposal
of another chemical or mixture of chemicals. In the
case of coincidental production of an impurity (i.e.,
an EPCRA Section 313 chemical that remains in the
product that is distributed in commerce), the de
minimis exemption, discussed in Section B.3.c of
these instructions, applies. The de minimis
exemption does not apply to byproducts (e.g., an
EPCRA Section 313 chemical that is separated from
a process stream and further processed or disposed
of). Certain EPCRA Section 313 chemicals may be
manufactured as a result of wastewater treatment or
other treatment processes. For example,
neutralization of wastewater containing nitric acid
can result in the coincidental manufacture of a
nitrate compound (solution), reportable as a member
of the nitrate compounds category.

15

-------
How to Determine if Your Facility Must Submit a Form R or Is Eligible to Use Form A
Process: The term "process" means the preparation
of a listed EPCRA Section 313 chemical, after its
manufacture, for distribution in commerce.
Processing is usually the incorporation of an
EPCRA Section 313 chemical into a product (see
Part II, Section 3.2 of these instructions for further
clarification). However, a facility may process an
impurity that already exists in a raw material by
distributing that impurity in commerce. Processing
includes preparation of the EPCRA Section 313
chemicals in the same physical state or chemical
form as that received by your facility, or preparation
that produces a change in physical state or chemical
form. The term also applies to the processing of a
mixture or other trade name product (see Section
B.4.b of these instructions) that contains a listed
EPCRA Section 313 chemical as one component.
Otherwise Use: The term "otherwise use" means
any use of an EPCRA Section 313 chemical,
including an EPCRA Section 313 chemical
contained in a mixture or other trade name product
or waste, that is not covered by the terms
manufacture or process. Otherwise use of an
EPCRA Section 313 chemical includes disposal,
stabilization (without subsequent distribution in
commerce), or treatment for destruction if:
(1)	The EPCRA Section 313 chemical that was
disposed of, stabilized, or treated for destruction
was received from off-site for the purposes of
further waste management;
Or
(2)	The EPCRA Section 313 chemical that was
disposed of, stabilized, or treated for destruction
was manufactured as a result of waste management
activities on materials received from off-site for the
purposes of waste management activities.
Relabeling or redistributing of the EPCRA Section
313 chemical where no repackaging of the EPCRA
Section 313 chemical occurs does not constitute an
otherwise use or processing of the EPCRA Section
313 chemical. (See 62 FR 23846 and Part II, Section
3.3 of these instructions for further clarification).

B.3.b. Persistent Bioaccumulative Toxic
(PBT) Chemicals and Chemical
Categories Overview
On October 29, 1999, EPA published a final rule (64
FR 58666) adding certain chemicals and chemical
categories to the EPCRA Section 313 list of toxic
chemicals and lowering the reporting threshold for
persistent bioaccumulative toxic (PBT) chemicals.
In addition, on January 17, 2001 EPA published a
final rule (66 FR 4500) that classified lead and lead
compounds as PBT chemicals and lowered their
reporting thresholds. The lower reporting thresholds
for lead applies to all lead except when lead is
contained in a stainless steel, brass or bronze alloy.
Dioxin and dioxin-like compounds, lead
compounds, mercury compounds and polycyclic
aromatic compounds (PACs) are the four PBT
chemical categories with lower reporting thresholds.
The 17 members of the dioxin and dioxin-like
compounds category and the 21 members of the
PACs category are listed in Table lie of these
instructions. The dioxin and dioxin-like compounds
category has the qualifier, "Manufacturing; and the
processing or otherwise use of dioxin and dioxin-
like compounds if the dioxin and dioxin-like
compounds are present as contaminants in a
chemical and if they were created during the
manufacturing of that chemical."
EPA has added six individual chemicals to the
EPCRA Section 313 list of toxic chemicals that also
had their thresholds lowered:
•	benzo(g,h,i)perylene,
•	benzo(j,k)fluorene (fluoranthene),
•	3-methylcholanthrene,
•	octachlorostyrene,
•	pentachlorobenzene, and
•	tetrabromobisphenol A (TBBPA).
Benzo(j,k)fluorene and 3-methyl-cholanthrene were
added as members of the polycyclic aromatic
compounds (PACs) chemical category.
EPA lowered the reporting thresholds for PBT
chemicals to either 100 pounds, 10 pounds, or in the
case of the dioxin and dioxin-like compounds
chemical category, to 0.1 grams. The table at the
beginning of Section B.4 of these instructions lists
the applicable manufacture, process, and otherwise
use thresholds for the listed PBT chemicals.
EPA eliminated the de minimis exemption for all
PBT chemicals (except lead when contained in
stainless steel, brass or bronze alloy). However, this
action does not affect the applicability of the de
minimis exemption to the supplier notification
requirements (40 CFR Section 372.45(d) (1)). In
addition, PBT chemicals are ineligible for range
reporting for on-site releases and transfers off-site
for further waste management. This will not affect
the applicability of range reporting of the maximum
amount on-site as required by EPCRA Section
313(g).
All releases and other waste management quantities
greater than 0.1 pounds of a PBT chemical (except
the dioxin and dioxin like compounds chemical
category) should be reported at a level of precision
supported by the accuracy of the underlying data
and estimation techniques on which the estimate is
based. If a facility's release or other waste
management estimates support reporting an amount
that is more precise than whole numbers, then the
more precise amount should be reported.
PBT chemical values of < 0.1 pounds (e.g., 0.07
pounds) should either be rounded up to 0.1 pound or
reported as they are if the underlying data and
estimation techniques support that level of precision.
It is up to the facility to determine, based on the
accuracy of the underlying data and the estimation
techniques on which the estimate is based, whether
it would be appropriate to round the value to 0.1
pound, report the value as is, or round the value to
zero.
For the dioxin and dioxin-like compounds chemical
category, which has a reporting threshold of 0.1
grams, facilities need only report all release and
other waste management quantities greater than 100
micrograms (i.e., 0.0001 grams). Notwithstanding
the numeric precision used when determining
reporting eligibility thresholds, facilities should
report on the Form R to the level of accuracy that
their data supports, up to seven digits to the right of
the decimal. EPA's reporting software and data
management systems support data precision to
seven digits to the right of the decimal. If a facility
has information on the individual members of the
dioxin and dioxin-like compounds category they
will also need to report the release and transfer
quantities of each congener (see instructions in
Section D).
Toxics Release Inventory Reporting Forms and Instructions

How to Determine if Your Facility Must Submit a Form R or Is Eligible to Use Form A
Lead and Lead Compounds
Lead and lead compounds are classified as PBT
chemicals and are subject to the lower
manufacturing, processing and otherwise use
threshold of 100 pounds. However, when lead is
contained in stainless steel, brass, or bronze alloys it
remains subject to the higher 25,000 pound
manufacturing and processing thresholds and the
10,000 pound otherwise use threshold.
Listed below are some important guidelines to use
when calculating threshold and release and other
waste management quantities for lead and lead
compounds:
1)	quantities of lead not contained in stainless
steel, brass or bronze alloy are applied to both
the 100-pound threshold and the 25,000/10,000
pound thresholds;
2)	quantities of lead that are contained in stainless
steel, brass or bronze alloys are only applied
toward the 25,000/10,000 pound thresholds;
3)	a facility may take the de minimis exemption for
those quantities of lead in stainless steel, brass,
or bronze alloys that meet the de minimis
standard (e.g., manufactured as an impurity).
Accordingly, the de minimis exemption may be
considered for quantities of lead in stainless
steel, brass, or bronze alloys but it may not be
considered for lead not in stainless steel, brass,
or bronze alloys;
4)	If a facility exceeds the 100-pound threshold for
lead other than in stainless steel, brass, or
bronze alloys, the facility may not apply Form
A eligibility for non-PBTs, range reporting in
Sections 5 and 6 of the Form R or the use of
whole numbers and 2 significant digits to any of
the lead they report. If a facility that exceeds the
25,000/10,000 pound threshold for lead in
stainless steel, brass, or bronze alloy without
tripping the 100-pound threshold for non-
alloyed lead, the facility may consider the Form
A requirements for non-PBTs, range reporting
in Sections 5 and 6 of the Form R, and the use
of whole numbers and 2 significant digits.
B.3.c. Activity Exemptions
Otherwise Use Exemptions. Certain otherwise uses
of listed EPCRA Section 313 chemicals are
specifically exempted:
•	Otherwise use as a structural component of the
facility;
•	Otherwise use in routine janitorial or facility
grounds maintenance;
•	Personal uses by employees or other persons;
•	Otherwise use of products containing EPCRA
Section 313 chemicals for the purpose of
maintaining motor vehicles operated by the
facility; and
•	Otherwise use of EPCRA Section 313 chemicals
contained in intake water (used for processing
or non-contact cooling) or in intake air (used
either as compressed air or for combustion).
The exemption of an EPCRA Section 313 chemical
otherwise used 1) as a structural component of the
facility; or 2) in routine janitorial or facility grounds
maintenance; or 3) for personal use by an employee
cannot be taken for activities involving process
related equipment.
Articles Exemption. EPCRA Section 313
chemicals contained in articles that are processed or
otherwise used at a covered facility are exempt from
threshold determinations and release and other
waste management calculations. The exemption
applies when the facility receives the article from
another facility or when the facility produces the
article itself. The exemption applies only to the
quantity of EPCRA Section 313 chemical present in
the article. If the EPCRA Section 313 chemical is
manufactured (including imported), processed, or
otherwise used at the covered facility other than as
part of the article, in excess of an applicable
threshold quantity, the facility is required to report
that use of a chemical (40 CFR Section 372.38(b)).
For an EPCRA Section 313 chemical in an item to
be exempt as part of the article, the item must meet
all the following criteria in the EPCRA Section 313
article definition; that is, it must be a manufactured
item (1) which is formed to a specific shape or
design during manufacture, (2) which has end use
functions dependent in whole or in part upon its
shape or design during end use, and (3) which does
not release a toxic chemical under normal conditions
of processing or use of the item at the facility.

How to Determine if Your Facility Must Submit a Form R or Is Eligible to Use Form A
If the processing or otherwise use of all like items
results in a total release of 0.5 pound or less of an
EPCRA Section 313 chemical in a reporting year to
any environmental medium, EPA will allow this
release to be rounded to zero, and the manufactured
items retain their article status. The 0.5 pound
threshold does not apply to each individual article,
but applies to the sum of all releases from
processing or otherwise use of all like articles. If all
the releases of like articles over a reporting year are
completely captured and recycled/reused on-site or
off-site, those items retain their article status. Any
amount that is released and is not recycled/reused
will count toward the 0.5 pound per year cut off
value.
The articles exemption applies to the normal
processing or use of articles. This exemption does
not apply to the manufacture of the article. EPCRA
Section 313 chemicals incorporated into articles
produced at a facility must be factored into
threshold determinations and release and other
waste management calculations.
If, in the course of processing or use, an item retains
its initial thickness or diameter, in whole or in part,
it meets the first part (i.e., it must be a manufactured
item which is formed to a specific shape or design
during manufacture) of the article definition. If the
item's basic dimensional characteristics are totally
altered during processing or otherwise use, the item
does not meet the first part of the definition. An
example of items that do not meet the definition
would be items that are cold extruded, such as lead
ingots, which are formed into wire or rods. On the
other hand, cutting a manufactured item into pieces
that are recognizable as the article would not change
the original dimensions as long as the diameter or
the thickness of the item remained the same; the
articles exemption would continue to apply. Metal
wire may be bent and sheet metal may be
cut,punched, stamped, or pressed without losing
their article status as long as the diameter of the wire
or tubing or the thickness of the sheet is not totally
changed.
What constitutes a release of an EPCRA Section
313 chemical is important since processing or
otherwise use of articles that result in a release to
the environment (or more than 0.5 pounds) negate
the article status and precludes eligibility for the
exemption. Cutting, grinding, melting, or other
processing of manufactured items could result in a
release of an EPCRA Section 313 chemical during
normal conditions of processing or otherwise use
and therefore negate the exemption as articles.
De Minimis Exemption. The de minimis exemption
allows facilities to disregard certain minimal
concentrations of non-PBT chemicals in mixtures or
other trade name products when making threshold
determinations and release and other waste
management calculations. The de minimis
exemption does not apply to the manufacture of an
EPCRA Section 313 chemical except if that EPCRA
Section 313 chemical is manufactured as an
impurity and remains in the product distributed in
commerce, or if the EPCRA Section 313 chemical is
imported below the appropriate de minimis level.
The de minimis exemption does not apply to a
byproduct manufactured coincidentally as a result of
manufacturing, processing, otherwise use, or any
waste management activities. The de minimis
exemption does not apply to any PBT chemical
(except lead when it is contained in stainless steel,
brass or bronze alloy) or PBT chemical category. A
list of PBT chemicals may be found in Section B.4
of these instructions.

How to Determine if Your Facility Must Submit a Form R or Is Eligible to Use Form A
When determining whether the de minimis
exemption applies to an EPCRA Section 313
chemical, the owner/operator must consider the
concentration of the non-PBT EPCRA Section 313
chemical in mixtures and other trade name products.
If the non-PBT EPCRA Section 313 chemical in a
mixture or other trade name product is manufactured
as an impurity, imported, processed, or otherwise
used and is below the appropriate de minimis
concentration level, then the quantity of the non-
PBT EPCRA Section 313 chemical in that mixture
or other trade name product does not have to be
applied to threshold determinations nor included in
release or other waste management determinations.
If a non-PBT EPCRA Section 313 chemical in a
mixture or other trade name product is below the
appropriate de minimis level, all releases and other
waste management activities associated with the
EPCRA Section 313 chemical in that mixture or
other trade name product are exempt from EPCRA
Section 313 reporting. It is possible to meet an
activity (e.g., processing) threshold for an EPCRA
Section 313 chemical on a facility wide basis, but
not be required to calculate releases or other waste
management quantities associated with a particular
process because that process involves only mixtures
or other trade name products containing the non-
PBT EPCRA Section 313 chemical below the de
minimis level.
EPA interprets the de minimis exemption such that
once a non-PBT EPCRA Section 313 chemical
concentration is at or above the appropriate de
minimis level in the mixture or other trade name
product threshold determinations and release and
other waste management calculations must be made,
even if that chemical later falls below the de minimis
level in the same mixture or other trade name
product. Thus, EPA considers reportable all releases
and other quantities managed as waste that occur
after the de minimis level has been met or exceeded.
If an EPCRA Section 313 chemical in a mixture or
other trade name product at or above de minimis is
brought on-site, the de minimis exemption never
applies.
De minimis levels for non-PBT EPCRA Section 313
chemicals and chemical categories are set at
concentration levels of either 1 percent or 0.1
percent; PBT chemicals and chemical categories do
not have de minimis levels with regard to this
exemption. The 0.1 percent de minimis levels are
dictated by determinations made by the National
Toxicology Program (NTP) in its Annual Report on
Carcinogens, the International Agency for Research
and Cancer (IARC) in its Monographs, or 29 CFR
part 1910, subpart Z. Therefore, once a non-PBT
chemical's status under NTP, IARC, or 29 CFR part
1910, subpart Z indicates that the chemical is a
carcinogen or potential carcinogen, the reporting
facility may disregard levels of the chemical below
the 0.1 percent de minimis concentration provided
that the other criteria for the de minimis exemption
are met. De minimis levels for chemical categories
apply to the total concentration of all chemicals in
the category within a mixture, not the concentration
of each individual category member within the
mixture.
De Minimis Application to the Processing or
Otherwise Use of a Mixture
The de minimis exemption applies to the processing
or otherwise use of a non-PBT EPCRA Section 313
chemical in a mixture. Threshold determinations and
release and other waste management calculations
begin at the point where the chemical meets or
exceeds the de minimis level. If a non-PBT EPCRA
Section 313 chemical is present in a mixture at a
concentration below the de minimis level, this
quantity of the substance does not have to be
included for threshold determinations, release and
other waste management reporting, or supplier
notification requirements. The exemption will apply
as long as the mixture containing de minimis
amounts of a non-PBT EPCRA Section 313
chemical never equals or goes above the de minimis
limit.

Concentration Ranges Straddling the De Minimis
Value
There may be instances in which the concentration
of a non-PBT chemical is given as a range
straddling the de minimis limit. Example 6
illustrates how the de minimis exemption should be
applied in such a scenario.
De Minimis Application in the Manufacture of
the Listed Chemical in a Mixture
The de minimis exemption generally does not apply
to the manufacturing of an EPCRA Section 313
chemical. However, the de minimis exemption may
apply to mixtures and other trade name products
containing non-PBT EPCRA Section 313 chemicals
that are imported into the United States. (See
Example 5)
The exemption also applies to non-PBT EPCRA
Section 313 chemicals that are manufactured as
impurities that remain in the product distributed in
commerce below the de minimis levels. The amount
remaining in the product is exempt from threshold
determinations. If the chemical is separated from the
final product, it cannot qualify for the exemption.
Any amount that is separated, or is separate, from
the product, is considered a byproduct and is subject
to threshold determinations and release and other
waste management calculations. Any amount of an
EPCRA Section 313 chemical that is manufactured
in a waste stream must be considered toward
threshold determinations and release and other
waste management calculations and accounted for
on Form R even if that chemical is manufactured
below the de minimis level.
The de minimis exemption also does not apply to
situations where a toxic chemical in waste is diluted
to below the de minimis level.

Laboratory Activities Exemption. EPCRA Section
313 chemicals that are manufactured, processed, or
otherwise used in a laboratory at a covered facility
under the direct supervision of a technically
qualified individual do not have to be considered for
threshold determinations and release and other
waste management calculations. However, pilot
plant scale and specialty chemical production does
not qualify for this laboratory activities exemption,
nor does the use of EPCRA Section 313 chemicals
for laboratory support activities, such as the use of
chemicals for equipment maintenance.
Coal Extraction Activities Exemption. If an
EPCRA Section 313 chemical is manufactured,
processed, or otherwise used in extraction by
facilities in NAICS codes 212111, 212112 and
212113, a person is not required to consider the
quantity of the EPCRA Section 313 chemical so
manufactured, processed, or otherwise used when
considering threshold determinations and release
and other waste management calculations (see
Example 8). Reclamation activities occurring
simultaneously with coal extraction activities (e.g.,
cast blasting) are included in the exemption.
However, otherwise use of ash, waste rock, or
fertilizer for reclamation purposes are not
considered part of extraction; non-exempt amounts
of EPCRA Section 313 chemicals contained in these
materials must be considered toward threshold
determinations and release and other waste
management calculations.
Metal Mining Overburden Exemption. If an
EPCRA Section 313 chemical that is a constituent
of overburden is processed or otherwise used by

B.4 Threshold Determinations
EPCRA Section 313 reporting is required if
threshold quantities are exceeded. Separate
thresholds apply to the amount of the EPCRA
Section 313 chemical that is manufactured,
processed or otherwise used.
You must submit a report for any EPCRA Section
313 chemical that is not listed as a PBT chemical
and which is:
•	Manufactured in excess of 25,000 pounds over
the calendar year;
•	Processed in excess of 25,000 pounds over the
calendar year; or
•	Otherwise used in excess of 10,000 pounds over
the calendar year.

How to Determine if Your Facility Must Submit a Form R or Is Eligible to Use Form A
B.4.a. How to Determine if Your
Facility Has Exceeded
Thresholds
To determine whether your facility has exceeded an
EPCRA Section 313 reporting threshold, compare
quantities of EPCRA Section 313 chemicals that
you manufacture, process, or otherwise use to the
respective thresholds for those activities. A
worksheet is provided in Figure 4A to assist
facilities in determining whether they exceed any of
the reporting thresholds for non-PBT chemicals;
Figures 4B-D provide worksheets for PBT
chemicals. (The worksheets can be found at the end
of section B.5.) These worksheets also provide a
format for maintaining reporting facility records.
Use of these worksheets is not required and the
completed worksheet(s) should not accompany
Form R reports submitted to EPA and the state or
tribe. Additionally, EPA provides an online
threshold screening tool at:
https://www.epa.gov/toxics-release-inventorv-tri-
program/tri-threshold-screening-tool.
Complete the appropriate worksheet for each
EPCRA Section 313 chemical or chemical category.
Base your threshold determination for EPCRA
Section 313 chemicals with qualifiers only on the
quantity of the EPCRA Section 313 chemical
satisfying the qualifier.
Use of the worksheets is divided into three steps:
•	Step 1 allows you to record the gross amount of
the EPCRA Section 313 chemical or chemical
category involved in activities throughout the
facility. Pure forms as well as the amounts of
the EPCRA Section 313 chemical or chemical
category present in mixtures or other trade name
products must be considered. The types of
activity (i.e., manufacturing, processing, or
otherwise using) for which the EPCRA Section
313 chemical is used must be identified because
separate thresholds apply to each of these
activities. A record of the information source(s)
used should be kept. Possible information
sources include purchase records, inventory
data, and calculations by a process engineer.
The data collected in Step 1 will be totaled for
each activity to identify the overall amount of
the EPCRA Section 313 chemical or chemical
category manufactured (including imported),
processed, or otherwise used.
•	Step 2 allows you to identify uses of the EPCRA
Section 313 chemical or chemical category that
were included in Step 1 but are exempt under
EPCRA Section 313. Do not include in Step 2
exempt quantities of the EPCRA Section 313
chemical not included in the calculations in Step
1. For example, if Freon contained in the
building's air conditioners was not reported in
Step 1, you would not include the amount as
exempt in Step 2. Step 2 is intended for use
when a quantity or use of the EPCRA Section
313 chemical is exempt while other quantities
require reporting. Note the type of exemption
for future reference. Also identify, if applicable,
the fraction or percentage of the EPCRA
Section 313 chemical present that is exempt.
Add the amounts in each activity to obtain a
subtotal for exempted amounts of the EPCRA
Section 313 chemical or chemical categories at
the facility.
• Step 3 involves subtracting the result of Step 2
from the results of Step 1 for each activity.
Compare this net sum to the applicable activity
threshold. If the threshold is exceeded for any of
the three activities, a facility must submit a
Form R for that EPCRA Section 313 chemical
or chemical category. Do not sum quantities of
the EPCRA Section 313 chemical that are
manufactured, processed, and otherwise used at
your facility, because each of these activities
requires a separate threshold determination. For
example, if in a calendar year you processed
20,000 pounds of a non-PBT EPCRA Section
313 chemical and you otherwise used 6,000
pounds of that same chemical, your facility has
not exceeded any applicable threshold and thus
is not required to report for that chemical.
Worksheets should be retained to document your
determination for reporting or not reporting, but
should not be submitted with the report.
You must submit a report if you exceed any
threshold for any EPCRA Section 313 chemical or
chemical category. For example, if your facility
processes 22,000 pounds of a non-PBT EPCRA
Section 313 chemical and also otherwise uses
16,000 pounds of that same chemical, it has
exceeded the otherwise use threshold (10,000
pounds for a non-PBT chemical) and your facility
must report even though it did not exceed the
process threshold (25,000 pounds for a non-PBT
chemical). In preparing your reports, you must
consider all non-exempted activities and all releases
and other waste management quantities of the
EPCRA Section 313 chemical from your facility,
Toxics Release Inventory Reporting Forms and Instructions
26

-------
How to Determine if Your Facility Must Submit a Form R or Is Eligible to Use Form A
not just releases and other waste management
quantities from the otherwise use activity.
Also note that threshold determinations are based
upon the actual amounts of an EPCRA Section 313
chemical manufactured, processed, or otherwise
used over the course of the calendar year. The
threshold determination may not relate to the
amount of an EPCRA Section 313 chemical brought
on-site during the calendar year. For example, if a
stockpile of 100,000 pounds of a non-PBT EPCRA
Section 313 chemical is present on-site but only
20,000 pounds of that chemical is applied to a
process, only the 20,000 pounds processed is
counted toward a threshold determination, not the
entire 100,000 pounds of the stockpile.
B.4.b. Threshold Determinations for
On-Site Reuse Operations
Threshold determinations of EPCRA Section 313
chemicals that are reused at the facility are based
only on the amount of the EPCRA Section 313
chemical that is added during the year, not the total
volume in the system. For example, a facility
operates a refrigeration unit that contains 15,000
pounds of anhydrous ammonia at the beginning of
the year. The system is charged with 2,000 pounds
of anhydrous ammonia during the year. The facility
has therefore "otherwise used" only 2,000 pounds of
anhydrous ammonia, a non-PBT EPCRA Section
313 chemical, which is below the otherwise use
threshold for anhydrous ammonia and is not
required to report (unless there are other "otherwise
use" activities of ammonia, that when taken
together, exceed the reporting threshold). If,
however, the whole refrigeration unit was recharged
with 15,000 pounds of anhydrous ammonia during
the year, then the facility would have exceeded the
otherwise use threshold, and would be required to
report.
This does not apply to EPCRA Section 313
chemicals "recycled" or "reused" off-site and
returned to a facility. Such EPCRA Section 313
chemicals returned to a facility are treated as the
equivalent of newly purchased material for purposes
of EPCRA Section 313 threshold determinations.
B.4.c. Threshold Determinations for
Ammonia
The listing for ammonia includes the modifier
"includes anhydrous ammonia and aqueous
ammonia from water dissociable ammonium salts
and other sources; 10 percent of total aqueous
ammonia is reportable under this listing." The
qualifier for ammonia means that anhydrous forms
of ammonia are 100 percent reportable and aqueous
forms are limited to 10 percent of total aqueous
ammonia. Therefore, when determining threshold
quantities, 100 percent of anhydrous ammonia is
included but only 10 percent of total aqueous
ammonia is included. If any ammonia evaporates
from aqueous ammonia solutions, 100 percent of the
evaporated ammonia is included in threshold
determinations.
For example, if a facility processes aqueous
ammonia, it has processed 100 percent of the
aqueous ammonia in that solution. If the ammonia
remains in solution, then 10 percent of the total
aqueous ammonia is counted towards the threshold.
If there are any evaporative losses of anhydrous
ammonia, then 100 percent of those losses must be
counted towards the processing threshold. If the
manufacturing, processing, or otherwise use
threshold for the ammonia listing is exceeded, the
facility must report 100 percent of these evaporative
losses in Sections 5 and 8 of the Form R.
B.4.d. Threshold Determinations for
Chemical Categories
A number of chemical compound categories are
subject to reporting. See Table lie for a listing of
these EPCRA Section 313 chemical categories.
When preparing threshold determinations for one of
these EPCRA Section 313 chemical categories, all
individual members of a category that are
manufactured, processed, or otherwise used must be
counted. Where generic names are used at a facility,
threshold determinations should be based on CAS
numbers. For example, Poly-Solv EB does not
appear among the reportable chemicals in Table Ha
or lib but its CAS number indicates Poly-Solv EB is
a synonym for ethylene glycol mono-n-butyl ether, a
member of the certain glycol ethers chemical
category (code N230). For chemical compound
categories, threshold determinations must be made
separately for each of the three activities. Do not
include in these threshold determinations for a
category any chemicals that are also individually
listed EPCRA Section 313 chemicals (see Table Ha
Toxics Release Inventory Reporting Forms and Instructions
27

-------
How to Determine if Your Facility Must Submit a Form R or Is Eligible to Use Form A
or lib). Individually listed EPCRA Section 313
chemicals are subject to their own individual
threshold determination.
Organic Compounds
For the organic compound categories, you are
required to account for the entire weight of all
compounds within a specific compound category
(e.g., glycol ethers) at the facility for BOTH the
threshold determination and release and other waste
management estimates.
Metal Category Compounds
Threshold determinations for metal category
compounds present a special case. If, for example,
your facility processes several different nickel
compounds, base your threshold determination on
the total weight of all nickel compounds processed.
However, if your facility processes both the
"parent" metal (nickel) as well as one or more
nickel compounds, you must make threshold
determinations for both nickel (CAS number 7440-
02-0) and nickel compounds (chemical category
code N495) because they are separately listed
EPCRA Section 313 chemicals. If your facility
exceeds thresholds for both the parent metal and
compounds of that same metal, EPA allows you to
file one combined report (e.g., one report for nickel
compounds, including nickel) because the release
information you will report in connection with metal
category compounds will be the total pounds of the
metal released. If you file one combined report, you
should put the name of the metal compound
category on the Form R. In the example above, the
facility that exceeded reporting thresholds for both
the nickel and nickel compounds chemical category
could submit a single Form R for the nickel
compounds chemical category, which would contain
release and other waste management information for
both nickel and nickel compounds. Do not put both
names on the Form R.
The case of metal category compounds involving
more than one metal should be noted. Some metal
category compounds may contain more than one
listed metal. For example, lead chromate is both a
lead compound and a chromium compound. In such
cases, if applicable thresholds are exceeded, you are
required to file two separate reports, one for lead
compounds and one for chromium compounds.
Apply the total weight of the lead chromate to the
threshold determinations for both lead compounds
and chromium compounds. (Note: Only the quantity
of each parent metal released or otherwise managed
as waste, not the quantity of the compound, would
be reported on the appropriate sections of both Form
Rs. See B.5.)
Nitrate Compounds (water dissociable;
reportable only when in aqueous solution)
For the category nitrate compounds (water
dissociable; reportable only when in aqueous
solution), the entire weight of the nitrate compound
is counted in making threshold determinations. A
nitrate compound is covered by this listing only
when in water and only if dissociated. If no
information is available on the identity of the type
of nitrate that is manufactured, processed or
otherwise used, assume that the nitrate compound
exists as sodium nitrate.
B.4.e Threshold Determination for
Persistent Bioaccumulative Toxic
(PBT) Chemicals
There are two separate thresholds for EPCRA
Section 313 PBT chemicals; these thresholds are set
based on the chemicals' potential to persist and
bioaccumulate in the environment. The
manufacturing, processing and otherwise use
thresholds for PBT chemicals is 100 pounds, while
for the subset of PBTs chemicals that are highly
persistent and highly bioaccumulative, it is 10
pounds. One exception is the dioxin and dioxin-like
compounds chemical category. The threshold for
this category is 0.1 gram. The PBT chemicals, their
CAS numbers or chemical category code, and their
reporting thresholds are listed in a table in the
introductory section of B.4. See Table lie of these
instructions for lists of individual members of the
dioxin and dioxin-like compounds chemical
category and the polycyclic aromatic compounds
(PACs) chemical category.
B.4.f. Mixtures and Other Trade Name
Products
EPCRA Section 313 chemicals contained in
mixtures and other trade name products must be
factored into threshold determinations and release
and other waste management calculations.
If your facility processed or otherwise used mixtures
or other trade name products during the calendar
year, you are required to use the best readily
available data (or reasonable estimates if such data
are not readily available) to determine whether the
toxic chemicals in a mixture meet or exceed the de
minimis concentration and, therefore, whether they
must be included in threshold determinations and
Toxics Release Inventory Reporting Forms and Instructions
28

-------
How to Determine if Your Facility Must Submit a Form R or Is Eligible to Use Form A
release and other waste management calculations. If
you know that a mixture or other trade name
product contains a specific EPCRA Section 313
chemical, combine the amount of the EPCRA
Section 313 chemical in the mixture or other trade
name product with other amounts of the same
EPCRA Section 313 chemical processed or
otherwise used at your facility for threshold
determinations and release and other waste
management calculations. If you know that a
mixture contains an EPCRA Section 313 chemical
but it is present below the de minimis level, you do
not have to consider the amount of the EPCRA
Section 313 chemical present in that mixture for
purposes of threshold determinations and release
and other waste management calculations. PBT
chemicals are not eligible for the de minimis
exemption except lead when it is contained in
stainless steel, brass or bronze alloy.
Observe the following guidelines in estimating
concentrations of EPCRA Section 313 chemicals in
mixtures when only limited information is available:
•	If you only know the upper bound
concentration, you must use it for threshold
determinations (40 CFR Section372.30(b)(ii)).
•	If you know the lower and upper bound
concentrations of an EPCRA Section 313
chemical in a mixture, EPA recommends you
use the midpoint of these two concentrations for
threshold determinations.
•	If you know only the lower bound
concentration, EPA recommends you subtract
out the percentages of any other known
components to determine a reasonable upper
bound concentration, and then determine a
midpoint.
•	If you have no information other than the lower
bound concentration, EPA recommends you
calculate a midpoint assuming an upper bound
concentration of 100 percent.
B.5 Release and Other Waste
Management Determinations for
Metals, Metal Category
Compounds, and Nitrate
Compounds
Metal Category Compounds
Although the complete weight of the metal category
compounds must be used in threshold
determinations for the metal compounds category,
only the weight of the metal portion of the metal
category compound must be considered for release
and other waste management determinations.
Remember that for metal category compounds that
consist of more than one metal, release and other
waste management reporting must be based on the
weight of each metal, provided that the appropriate
thresholds have been exceeded.
Metals and Metal Category Compounds
For compounds within the metal compound
categories, only the metal portion of the metal
category compound must be considered in
determining release and other waste management
quantities for the metal category compounds.
Therefore, if thresholds are separately exceeded for
both the "parent" metal and its compounds, EPA
allows you to file a combined Form R for the
"parent" metal and its category compounds. This
Form R would contain all of the release and other
waste management information for both the
"parent" metal and metal portion of the related
metal category compounds. For example, you
exceed thresholds for chromium. You also exceed
thresholds for chromium compounds. Instead of
filing two Form Rs you can file one combined Form
R. This Form R would contain information on
quantities of chromium released or otherwise
managed as waste and the quantities of the
chromium portion of the chromium compounds
released or otherwise managed as waste. When
filing one combined Form R for an EPCRA Section
313 metal and metal compound category, facilities
should identify the chemical reported as the metal
compound category name and code in Section 1 of
the Form R.
Note that these instructions do not apply to the Form
A. See Section B.6.g for reporting instructions for
reporting metals and metal category compounds
using the Form A. See Appendix B for more
information about reporting the release and other
waste management of metals and metal compounds.
Nitrate Compounds (water dissociable;
reportable only in aqueous solution)
Although the complete weight of the nitrate
compound must be used for threshold
determinations for the nitrate compounds category
only the nitrate portion of the compound should be
used for release and other waste management
calculations.

How to Determine if Your Facility Must Submit a Form R or Is Eligible to Use Form A
B. 6. Facility Eligibility Determination
for Alternate Threshold and for
Reporting on TRI Form A
Certification Statement
This section will help to determine whether you can
submit the simplified Form A Certification
Statement (hereafter referred to as Form A). The
criteria are based on the total annual reportable
amount of the listed chemical or chemical category
and the amount manufactured, processed, or
otherwise used. Note that, effective in Reporting
Year 2008, the TRI Burden Reduction Rule has
been voided by Congress. The criterion for using
Form A has returned to what they were prior to
Reporting Year 2006. The criteria are explained
below. For more information about the final rule,
see the TRI homepage at:
https://www.epa.gov/toxics-release-inventorv-tri-
program/tri-laws-rulemakings-and-notices.
B.6.a. Alternate Threshold
On November 30, 1994, EPA published a final rule
(59 FR 61488) that provides qualifying facilities an
alternate threshold of 1 million pounds. Eligible
facilities wishing to take advantage of this option
may certify on a simplified two-page form referred
to as Form A Certification Statement and do not
have to use Form R. The "TRI Alternate Threshold
for Facilities with Low Annual Reportable
Amounts," provides facilities otherwise meeting
EPCRA section 313 reporting thresholds the option
of certifying on Form A provided that they do not
exceed 500 pounds for the total annual reportable
amount (defined below) for that chemical, and that
their amounts manufactured or processed or
otherwise used do not exceed one-million pounds.
As with determining section 313 reporting
thresholds, amounts manufactured, processed, or
otherwise used are to be considered independently.
This modification does not apply to forms being
submitted on or before July 1, 1995 (covering the
1994 reporting year). If you fill out a Form A for an
EPCRA section 313 chemical, do not fill out a Form
R for that same chemical.
However, there is an exception to the alternate
threshold rule described in the preceding paragraph.
All PBT chemicals (except certain instances of
reporting lead in stainless steel, brass or bronze
alloys) are excluded from eligibility for the alternate
threshold.
B.6.b. What is the Form A Certification
Statement?
The Form A, which is described as the "certification
statement" in 59 FR 61488, is intended as a means
to reduce the compliance burden associated with
EPCRA section 313. If a facility chooses to use
Form A as a substitute for Form R for any eligible
chemical, it must be submitted on an annual basis.
Facilities wishing to take advantage of this burden
reducing option may only submit Form A for
chemicals that meet the conditions described in
section B.6.a, Alternate Threshold, and should not
submit a Form R to the TRI Data Processing Center
for the same chemicals. The information submitted
on the Form A includes facility identification
information and the chemical or chemical category
identity. The information submitted on the Form A
will appear in the TRI data base in the same manner
that information submitted on Form R appears. An
approved Form A can be accessed via TRI-MEweb
or from the EPA TRI website.
B.6.c. What Is the Annual Reportable
Amount (ARA)?
For the purpose of this optional reporting
modification, the annual reportable amount (ARA)
is equal to the combined total quantities of the
following waste management activities:
•	released at the facility (including disposed of
within the facility),
•	treated at the facility (as represented by amounts
destroyed or converted by treatment processes),
•	recovered at the facility as a result of recycling
operations,
•	combusted for the purpose of energy recovery at
the facility, and
•	amounts transferred from the facility to off-site
locations for the purpose of recycling, energy
recovery, treatment, and/or disposal.
These quantities correspond to the sum of amounts
reportable for data elements on EPA Form R as Part
II column B of section 8, data elements 8.1 (quantity
released), 8.2 (quantity used for energy recovery on-
site), 8.3 (quantity used for energy recovery off-
site), 8.4 (quantity recycled onsite), 8.5 (quantity
recycled off-site), 8.6 (quantity treated on-site), and
8.7 (quantity treated off-site).
B.6.d. Recordkeeping
Each owner or operator who determines that they
are eligible, and wishes to apply the alternate
Toxics Release Inventory Reporting Forms and Instructions
35

-------
How to Determine if Your Facility Must Submit a Form R or Is Eligible to Use Form A
threshold to a particular chemical, must retain
records substantiating this determination for a
period of three years from the date of the
submission of the Form A. These records must
include sufficient documentation to support
calculations as well as the calculations made by the
facility that confirm their eligibility for each
chemical for which the alternate threshold was
applied.
A facility that fits within the category description,
and manufactures, processes or otherwise uses no
more than one million pounds of an EPCRA Section
313 chemical annually, and whose owner/operator
elects to take advantage of the alternate threshold, is
not considered an EPCRA Section 313 covered
facility for that chemical for the purpose of
submitting a Form R. This determination may
provide further regulatory relief from other federal
or state regulations that apply to facilities on the
basis of their EPCRA Section 313 reporting status.
A facility will need to reference other applicable
regulations to determine if their actual requirements
may be affected by this reporting modification.
B.6.e. Multi-establishment Facilities
For the purposes of using Form A, the facility must
also make its determination based upon the entire
facility's operations including all of its
establishments (see 59 FR 61488 for greater detail).
If the facility as a whole is able to take advantage of
the alternate threshold, a single Form A is required.
The eligibility to submit a Form A must be made on
a whole facility determination. Thus, all of the
information necessary to make the determination
must be assembled to the facility level.
B.6.f. Metals and Metal Category
Compounds
For metal category compounds, the amount applied
toward the ARA is the amount of parent metal waste
that is reported on Form R, but the thresholds apply
to the amount of metal category compounds
manufactured, processed, or otherwise used. For
Form A certification involving both listed parent
metals and associated metal compounds, the one
million pound alternate threshold must be applied
separately to the listed parent metal and the
associated metal compound(s). Threshold
determinations must be made independently for
each because they are separately listed EPCRA
Section 313 chemicals.
•	If the threshold is exceeded for the listed parent
metal but not the associated metal category
compounds, then the releases of metal reported
on Form R for the parent metal need not include
the releases from the metal category
compounds.
•	If both the parent metal and the associated metal
compounds exceed the alternate threshold, then
the facility has the option of filing one Form R
for both, using the metal category compound
name and reporting total releases based on
parent metal content.
•	If neither the parent metal nor the associated
metal compounds exceed the alternate
threshold, then the facility must use a separate
listing on Form A for each, since the reporting
thresholds must be applied to each listed parent
metal and all compounds in the associated
compound category. EPA believes it is
appropriate to make the distinction between
filing the Form R and Form A because the Form
R accounts for amounts of metal released or
otherwise managed and Form A verifies that the
alternate threshold for each listed chemical or
chemical category has not been exceeded.
Similarly, separate listings on Form A must be
submitted for all other listed chemicals even if EPA
allows one listing on Form R to be filed for two or
more listed chemicals (e.g., o-xylene, p-xylene and
xylene (mixed isomers)). For example, if a facility
processes in three separate process streams, xylene
(mixed isomers), o-xylene, and p-xylene, and
exceeds the conditions of the alternate threshold for
each of these listed substances, the facility may
combine the appropriate information on the o-
xylene, p-xylene, and xylene (mixed isomers) into
one Form R, but cannot combine the reports into
one listing on Form A.
Facilities that process o-xylene, p-xylene, and
xylene (mixed isomers) in separate process streams
and do not exceed the conditions of the alternate
threshold for one or more of the compounds may
submit a separate Form A for each of the forms of
xylene meeting the alternate threshold and report on
Form R for those forms that do not. Similar to
reporting on the parent metals and their associated
category compounds described above, facilities that
separately process all types (i.e., isomers) of xylene
with individual activity levels within the conditions
of the alternate threshold should file a separate Form
A for each type of xylene.

Instructions for Completing TRI Forms R and A
Instructions for Completing TRI
Forms R and A
The following instructions provide information on
how to enter data on Forms R and A for non-trade
secret reporting using TRI-MEweb. Supplemental
instructions for submitting trade secret claims are
provided in Appendix G.
TRI-MEweb collects the same facility identification
information and chemical specific information that
facilities previously submitted on the paper TRI
Forms. In some cases, TRI-MEweb does not
sequentially follow the Sections numerically as
listed on the Forms. As such, the TRI-MEweb
experience differs somewhat from the sequential
nature of the instructions in this document.
Facility identification information provided in Part I
is entered only once per facility in TRI-MEweb and
is duplicated on all forms submitted, with the
exception of technical and public contact which are
collected for each form separately (See Part I,
Sections 4.3 and 4.4). For facilities that have
previously submitted TRI Forms, the facility
information remains with the facility's profile and
needs to be updated only if facility or parent
company changes have occurred.
Chemical specific information on Part II (including
technical and public contact information) is entered
separately for each chemical reported.

The reporting year is the calendar year to which the
reported information applies, not the year in which
you are submitting the report. Information for the
2016 reporting year must be submitted on or before
July 1,2017.
Section 2. Trade Secret Information
Trade secret submission is not supported by TRI-
MEweb. As such, Section 2 is not to be completed
by TRI-MEweb users for non-trade secret reports.
For instructions on completing trade secret
submissions, see Appendix G of these instructions.
Section 3. Certification
For both Form R and Form A, the certification
statement must be signed by a senior official with
management responsibility for the person (or
persons) completing the form. A senior management
official must certify the accuracy and completeness
of the information reported on the form by signing
and dating the form.
Electronic certification of completed forms prepared
using TRI-MEweb is performed by certifying
officials who have signed an Electronic Signature
Agreement (ESA) and TRIFID Certification
Agreement. For more information regarding
certification of forms, see Section A.2.
Unlike the certification statement contained on
Form R, the certification statement provided on the
Alternate Threshold Form A pertains to the
facility's eligibility of having met the conditions as
described in 40 CFR Section 372.27.
Section 4. Facility Identification
4.1 Facility Name, Location, TRI Facility
Identification Number and Tribal
Country Name
Enter the full name that the facility presents to the
public and its customers in doing business (e.g., the
name that appears on invoices, signs, and other
official business documents). Do not use a nickname
for the facility (e.g., Main Street Plant) unless that is
the legal name of the facility under which it does
business. Also enter the physical street address,
mailing address, city, county, three digit BIA code,
if applicable, state, and ZIP code in the space
provided. The street address provided must be the
location where the EPCRA Section 313 chemicals
are manufactured, processed, or otherwise used.
You may not use PO Box as a facility address. If
your mailing address and street address are the
same, you should enter NA in the space for the
mailing address. If the mailing address is outside of
the US, include the FIPS country code.
If your facility is not in a county, put the name of
your city, district (for example, District of
Columbia), or parish (if you are in Louisiana) in the
county block of the Form R and Form A as well as
in the county field of TRI-MEweb. "NA" or "None"
are not acceptable entries. TRI-MEweb provides a
drop-down menu for the county name, including
city districts and parish names.
If your facility is located on Indian country as
defined by 18 USC §1151 you must enter the three
digit Bureau of Indian Affairs (BIA) tribal code in
the "City/County/Tribe/State/ZIP code" field. The
BIA tribal codes are listed in Table III of the RFI.
Facilities using TRI-MEweb to complete their forms
will be asked if they are located within a tribe's
Indian country and, upon answering "yes", be taken
to a look-up table to determine the correct BIA
code.
If your facility is not located (overwhelming
majority of TRI facilities are not in Indian Country)
in Indian country as defined by 18 USC §1151 you
must enter only the city, county (as applicable), state
and zip code.
Location information for a facility that has
previously submitted data to EPA.
If your facility has submitted a Form R or A in
previous reporting years, a TRI Facility
Identification Number (TRIFID) has already been
assigned to your facility. If you do not know your
facility's information used in prior years'
submissions, contact your Regional TRI Program
representative, or utilize Envirofacts on the Web to
look up the address, facility name, or TRIFID at:
https://www3 .epa.gov/enviro.
If you have previously submitted data for your
facility using TRI-MEweb, the facility information
including TRIFID remains with your profile. If you
have not submitted using TRI-MEweb, then you can
add your facility to your profile using the 6-digit
access key, which is e-mailed to all technical
contacts, preparers, and certifying officials at
facilities reporting for the prior year, or by
Toxics Release Inventory Reporting Forms and Instructions

Part I Facility Identification Information
submitting the TRIFID and technical contact
information.
Location information for a facility that has
previously submitted data to EPA, but has
changed physical location.
If your facility has moved, you will need to request
that a new TRIFID be assigned to your facility. To
request a new TRIFID, add a new facility account to
TRI-MEweb and choose to report as a new reporting
facility (option 3). TRI-MEweb will automatically
generate a new TRIFID for your facility. The
TRIFID assigned to your new reporting facility
should be used in all future reporting of TRI data.
Location information for a facility that has
changed ownership, but has not changed physical
location.
The TRIFID is established by the first Form R or A
submitted by a facility at a particular location. Only
a change in address warrants filing as a new facility;
otherwise, the TRIFID is retained by the facility
even if the facility changes name, ownership,
production processes, NAICS codes, etc.
If your facility has changed ownership during the
reporting year but not its physical location, the
facility does not require a new TRIFID. Use the
TRIFID assigned to previous owner. TRI-MEweb
can be used to update facility information due to
change of ownership.
Location reporting TRI releases for the first time
to EPA.
If your facility is reporting for the first time, upon
creating your CDX account, and adding the TRI-
MEweb application, you will be prompted to add a
new facility account into TRI-MEweb. TRI-MEweb
will automatically generate a new TRIFID for your
facility. The TRIFID assigned to your new
reporting facility should be used in all future
reporting of TRI data.
4.2 Full or Partial Facility Indication and
Federal Facility Designation
Full or Partial Facility Indication (Form R only)
EPCRA Section 313 requires reports by "facilities,"
which are defined as "all buildings, equipment,
structures, and other stationary items which are
located on a single site or on contiguous or adjacent
sites and which are owned or operated by the same
person (or by any person which controls, is
controlled by, or under common control with such
person). A facility may contain more than one
establishment."
EPCRA Section 313 defines establishment as "an
economic unit, generally at a single physical
location, where business is conducted or where
services or industrial operations are performed."
Under Section 372.30(c) of the reporting rule, you
may submit a separate Form R for each
establishment or for groups of establishments in
your facility, provided all releases and other waste
management activities and source reduction
activities involving the EPCRA Section 313
chemical from the entire facility are reported. This
allows you the option of reporting separately on the
activities involving an EPCRA Section 313
chemical at each establishment, or group of
establishments (e.g., part of a covered facility),
rather than submitting a single Form R for that
EPCRA Section 313 chemical for the entire facility.
However, if an establishment or group of
establishments does not manufacture, process, or
otherwise use or release or otherwise manage as
waste an EPCRA Section 313 chemical, you do not
have to submit a report for that establishment or
group of establishments for that particular chemical.
(See also Section B.2.b of these instructions.)
A covered facility must report all releases and other
waste management activities and source reduction
activities of an EPCRA Section 313 chemical if the
facility meets a reporting threshold for that EPCRA
Section 313 chemical. Whether submitting a report
for the entire facility or separate reports for the
establishments, the threshold determination must be
made based on the entire facility. Indicate in Section
4.2 whether your report is for the entire covered
facility as a whole or for part of a covered facility
(i.e., one or more establishments).
In TRI-MEweb, facilities that wish to submit
separate Form Rs for each establishment or group of
establishments may select "Reporting by Part" with
the Select Facility page to set up unique
Toxics Release Inventory Reporting Forms and Instructions
39

-------
Part I Facility Identification Information
establishments within the particular facility. All
establishments reporting by part use the same
TRIFID but should provide unique facility names.
Note that the reporting by part option is not
applicable for facilities submitting a Form A for a
TRI chemical. Unlike the Form R, the Form A does
not utilize Sections 4.2a or 4.2b, which provide the
option of reporting full or partial facility
information if the facility is composed of several
distinct establishments.
Federal Facility Designation
Executive Order 13423 directs federal facilities to
comply with Right-To-Know Laws and Pollution
Prevention Requirements. In TRI-MEweb, users
should select the appropriate button for: 1) federal
facility (Section 4.2c), 2) GOCO facility (Section
4.2d), or 3) neither. Federal facilities should select
only 'federal facility' even if their TRI reports
contain release and other waste management
information from contractors located at the facility.
Contractors at federal facilities that are required by
EPCRA Section 313 to file TRI reports
independently of the federal facility, should select
GOCO. This information is important to prevent
duplication of federal facility data. (See Appendix A
for further guidance on these instructions.)
4.3 Technical Contact
In TRI-MEweb, facilities must enter the name and
telephone number (including area code) of a
technical representative whom EPA, state, or tribal
officials may contact for clarification of the
information reported on Form R or A. If possible,
this number should be for the technical
representative rather than a general number for the
facility. An email address should also be entered for
this person. EPA encourages facilities to provide an
email address for the Technical Contact on their TRI
submissions because they will be able to receive
important program updates and email alerts
notifying them when their eFDP has been updated
and published for their review. If the technical
contact does not have an email address, leave the
field blank. This contact person does not have to be
the same person who prepares the report or signs the
certification statement and does not necessarily need
to be someone at the location of the reporting
facility. However, this person should be familiar
with the details of the report so that he or she can
answer questions about the information provided.
As facilities may report unique technical contacts
for each form, technical contact details are entered
in TRI-MEweb with chemical-specific data rather
than facility-identification information.
4.4	Public Contact
In TRI-MEweb, facilities must enter the name and
telephone number (including area code) of a person
who can respond to questions from the public about
the form. You should also enter an e-mail address
for this person. If the public contact does not have
an email address, leave the field blank. If you
choose to designate the same person as both the
Technical and the Public Contact, or you do not
have a Public Contact, you may enter "Same as
Section 4.3" in this space. This contact person does
not have to be the same person who prepares the
form or signs the Certification Statement and does
not necessarily need to be someone at the location
of the reporting facility. As facilities may report
unique public contacts for each form, public contact
details are entered in TRI-MEweb with chemical-
specific data rather than facility-identification
information.
4.5	North American Industry Classification
System (NAICS) Codes
Enter the appropriate six-digit North American
Industry Classification System (NAICS) Code that
is the primary NAICS Code for your facility in
Section 4.5(a). Use 2012 NAICS codes for RY 2013
-2016 reporting and 2007 NAICS codes for RY
2006 - 2012 reporting. Enter any other applicable
NAICS for your facility in 4.5 (b)-(f), also called
"secondary NAICS codes" in TRI-MEweb. If you
do not know your NAICS code(s), consult the 2012
NAICS Manual or check the SIC to NAICS
crosswalk tables at: http://www.census. gov.
The North American Industry Classification System
(NAICS) is the economic classification system that
replaced the 1987 SIC code system. A Federal
Register notice was published on June 6, 2006 (71
FR 32464) adopting 2007 NAICS codes for TRI
reporting. A direct final rule was published July 18,
2013 (78 FR 42875), adopting 2012 NAICS codes
for RY 2013 and subsequent years. Table I lists all
industries that are covered under EPCRA 313 and
their corresponding 2012 NAICS codes.

Part I Facility Identification Information
4.6 Dun & Bradstreet Number(s)
Enter the nine-digit number assigned by Dun &
Bradstreet (D&B) for your facility or each
establishment within your facility. These numbers
code the facility for financial purposes. This number
may be available from your facility's treasurer or
financial officer. You can also obtain the numbers
from Dun & Bradstreet by calling 1-888-814-1435,
or by visiting this website:
httos://www.dnb.com/prodiict/dl\\7form cc4.htm.
If a facility does not subscribe to the D&B service, a
number can be obtained, toll free at 800 234-3867
(8:00 AM to 6:00 PM, EST) or on the Web at:
http://www.dnb.com.
If none of your establishments has been assigned a
D&B number, you should check "D&B Numbers
Not Applicable." If only some of your
establishments have been assigned D&B numbers,
enter those numbers in Part I, section 4.6.
Section 5. Parent Company
Information
You must provide information on your parent
company. For TRI Reporting purposes, your parent
company is the highest level company, located in
the United States, and that directly owns at least 50
percent of the voting stock of your company. If
there is no higher level U.S. company, select the
"No U.S. Parent Company (for TRI reporting
purposes)" check box. Corporate names should be
treated as parent company names for companies
with multiple facility sites. For example, the
Bestchem Corporation is not owned or controlled by
any other corporation but has sites throughout the
country whose names begin with Bestchem. In this
case, Bestchem Corporation should be listed as the
parent company. Note that a facility that is a 50:50
joint venture is its own parent company. When a
facility is owned by more than one company and
none of the facility owners directly owns at least 50
percent of its voting stock, the facility should
provide the name of the parent company of either
the facility operator or the owner with the largest
ownership interest in the facility.
5.1	Name of Parent Company
Enter the name of the corporation or other business
entity that is your highest level U.S. parent
company. If your facility has no higher level U.S.
company, select the "No U.S. Parent Company (for
TRI reporting purposes)" check box.
To improve data quality, TRI standardizes parent
company names. TRI-MEweb is preloaded with the
standardized parent company names. A full list of
parent company names for RY 2016 is available for
download at: https://www2.epa. gov/toxics-release-
inventorv-tri-program/standardized-parent-
company-names.
5.2	Parent Company's Dun & Bradstreet
Number
Enter the D&B number for your ultimate U.S.
parent company, if applicable. The number may be
obtained from the treasurer or financial officer of
the company or by calling 1-888-814-1435, or by
visiting this website:
https://www.dnb.com/product/dlw/form cc4.htm.
If your parent company does not have a D&B
number, you should check "Parent Company D&B
Number Not Applicable."

Part II Chemical Identification Information
D. Part II. Chemical
Identification Information
(Form R & A)
In Part II, you are to report on:
•	The EPCRA Section 313 chemical being
reported;
•	The type of reporting form used (i.e., Form R or
Form A);
•	The general uses and activities involving the
EPCRA Section 313 chemical at your facility
(Form R only);
•	On-site releases of the EPCRA Section 313
chemical from the facility to air, water, and land
(Form R only);
•	Quantities of the EPCRA Section 313 chemical
transferred to off-site locations (Form R only);
•	Information for on-site and off-site disposal,
treatment, energy recovery, and recycling of the
EPCRA Section 313 chemical (Form R only);
and
•	Source reduction activities (Form R only).
In TRI-MEweb, chemical specific information is
entered by initiating a blank form for a chemical or
chemical category. You may use the "Add New
Chemical Forms" search tool to look up chemical
and chemical categories by name or Chemical
Abstracts Service (CAS) number to begin a new
TRI reporting form. Alternately, you may use the
Import Data function to create and pre-populate
forms based on prior year forms submitted by the
facility. TRI-MEweb will prompt users to indicate
whether the form should be a TRI Form R or Form
A.
The TRI listed chemicals for RY 2016 are listed
both alphabetically and by CAS registry number in
Table II. Chemical categories are listed separately in
Table lie. TRI-MEweb will not accept forms for
chemicals not listed in a particular reporting year.
For example, TRI-MEweb will not accept forms for
the nonylphenol category prior to RY 2016 as it was
first added for RY 2016. Facilities reporting a
generic name provided by a supplier should see
instructions in Section 2.
Reporting on the Alternate Threshold Form A
Certification Statement for metals, metal category
compounds, and mixed isomers differs somewhat
from Form R reporting. Please refer to Section B.6.g
for these guidelines.

Part II Chemical Identification Information
Section 2. Mixture Component
Identity (Form R&A)
Complete this section only if you are reporting for
an EPCRA 313 chemical whose identity has been
withheld by the chemical supplier. You do not need
to supply trade secret substantiation forms for this
EPCRA Section 313 chemical because it is your
supplier who is claiming the chemical identity a
trade secret.
2.1 Generic Chemical Name Provided by
Supplier
Enter the generic chemical name in this section only
if the following three conditions apply:
1)	You determine that the mixture contains an
EPCRA Section 313 chemical but the only
identity you have for that chemical is a generic
name;
2)	You know either the specific concentration of
that EPCRA Section 313 chemical component
or a maximum or average concentration level;
and
3)	You multiply the concentration level by the total
annual amount of the whole mixture processed
or otherwise used and determine that you meet
the process or otherwise use threshold for that
single, generically identified mixture
component.
To begin a TRI Form R or A for a generic chemical
in TRI-MEweb, navigate to the Forms Home page,
click the "Add Form(s)" button for the facility
reporting on a generic chemical, click the Generic
Chemical Name Provided by Supplier link on the
search window pop-up, and then enter the generic
chemical name. The generic chemical name may not
be that of a listed TRI chemical or chemical
category and must be less than 70 characters in
length. Click the "Begin Form" button next to the
generic chemical added to the list of forms for the
facility to prepare the TRI form.
Section 3. Activities and Uses of the
EPCRA Section 313 Chemical at
the Facility (Form R)
[Note that the remaining Part II Sections apply to
the Form R only.]
Indicate whether the EPCRA Section 313 chemical
is manufactured (including imported), processed, or
otherwise used at the facility and the general nature
of such activities and uses at the facility during the
calendar year (see Figure 5). You are not required to
report on Form R the quantity manufactured,
processed or otherwise used. Report activities that
take place only at your facility, not activities that
take place at other facilities involving your products.
You must check all the boxes in this section that
apply. Refer to the definitions of "manufacture,"
"process," and "otherwise use" in Section B.3.a or
Part 40, Section 372.3 of the CFR for additional
explanations.
3.1 Manufacture the EPCRA Section 313
Chemical
Persons who manufacture (including import) the
EPCRA Section 313 chemical must check at least
one of the following:
a.	Produce — The EPCRA Section 313
chemical is produced at the facility.
b.	Import — The EPCRA Section 313 chemical
is imported by the facility into the Customs
Territory of the United States. (See Section
B.3.a of these instructions for further
clarification of import.)
And check at least one of the following:
c.	For on-site use/processing — The EPCRA
Section 313 chemical is produced or imported
and then further processed or otherwise used
at the same facility. If you check this block,
generally you should also check at least one
item in Part II, Section 3.2 or 3.3.
d.	For sale/distribution — The EPCRA Section
313 chemical is produced or imported
specifically for sale or distribution outside the
manufacturing facility.

-------
Part II Chemical Identification Information
e.	As a byproduct — The EPCRA Section 313
chemical is produced coincidentally during
the manufacture, processing, or otherwise use
of another chemical substance or mixture and,
following its production, is separated from
that other chemical substance or mixture.
EPCRA Section 313 chemicals produced as a
result of waste management are also
considered byproducts.
f.	As an impurity — The EPCRA Section 313
chemical is produced coincidentally as a
result of the manufacture, processing, or
otherwise use of another chemical but is not
separated and remains in the mixture or other
trade name product with that other chemical.
In summary, if you are a manufacturer of the
EPCRA Section 313 chemical, you must check (a)
and/or (b), and at least one of (c), (d), (e), and (f) in
Section 3.1.
3.2 Process the EPCRA Section 313
Chemical
Persons who process the EPCRA Section 313
chemical must check at least one of the following:
a.	As a reactant — A natural or synthetic
EPCRA Section 313 chemical is used in
chemical reactions for the manufacture of
another chemical substance or of a product.
Includes but is not limited to, feedstocks, raw
materials, intermediates, and initiators.
b.	As a formulation component — An EPCRA
Section 313 chemical is added to a product (or
product mixture) prior to further distribution of
the product that acts as a performance enhancer
during use of the product. Examples of EPCRA
Section 313 chemicals used in this capacity
include, but are not limited to, additives, dyes,
reaction diluents, initiators, solvents, inhibitors,
emulsifiers, surfactants, lubricants, flame
retardants, and rheological modifiers.
c.	As an article component — An EPCRA
Section 313 chemical becomes an integral
component of an article distributed for
industrial, trade, or consumer use. One
example is the pigment components of paint
applied to a chair that is sold.
d.	Repackaging — This consists of processing or
preparation of an EPCRA Section 313
chemical (or product mixture) for distribution
in commerce in a different form, state, or
quantity. This includes, but is not limited to,
the transfer of material from a bulk container,
such as a tank truck to smaller containers such
as cans or bottles.
e.	As an impurity — The EPCRA Section 313
chemical is processed but is not separated and
remains in the mixture or other trade name
product with that/those other chemical(s).
3.3 Otherwise Use the EPCRA Section 313
Chemical (non-incorporative activities)
Persons who otherwise use the EPCRA Section 313
chemical must check at least one of the following:
a.	As a chemical processing aid — An EPCRA
Section 313 chemical that is added to a
reaction mixture to aid in the manufacture or
synthesis of another chemical substance but is
not intended to remain in or become part of the
product or product mixture is otherwise used as
chemical processing aid. Examples of such
EPCRA Section 313 chemicals include, but are
not limited to, process solvents, catalysts,
inhibitors, initiators, reaction terminators, and
solution buffers.
b.	As a manufacturing aid — An EPCRA
Section 313 chemical that aids the
manufacturing process but does not become
part of the resulting product and is not added to
the reaction mixture during the manufacture or
synthesis of another chemical substance is
otherwise used as a manufacturing aid.
Examples include, but are not limited to,
process lubricants, metalworking fluids,
coolants, refrigerants, and hydraulic fluids.
c.	Ancillary or other use — An EPCRA Section
313 chemical that is used at a facility for
purposes other than aiding chemical processing
or manufacturing as described above is
otherwise used as an ancillary or other use.
Examples include, but are not limited to,
cleaners, degreasers, lubricants, fuels, EPCRA
Section 313 chemicals used for treating wastes,
and EPCRA Section 313 chemicals used to
treat water at the facility.

If the EPCRA Section 313 chemical present at your
facility was part of a mixture or other trade name
product, determine the maximum quantity of the
EPCRA Section 313 chemical present at the facility
by calculating the weight percent of the EPCRA
Section 313 chemical only.
Do not include the weight of the entire mixture or
other trade name product. These data may be found
in the Tier II form your facility may have prepared
under Section 312 of EPCRA. See Part 40, Section
372.30(b) of the CFR for further information on
how to calculate the weight of the EPCRA Section
313 chemical in the mixture or other trade name
product. For EPCRA Section 313 chemical
categories (e.g., nickel compounds), include all
chemical compounds in the category when
calculating the maximum amount, using the entire
weight of each compound.

Part II Chemical Identification Information
Section 5. Quantity of the Toxic
Chemical Entering Each
Environmental Medium On-site
(Form R)
In Section 5, you must account for the total
aggregate on-site releases of the EPCRA Section
313 chemical to the environment from your facility
for the calendar year.
On-site releases to the environment include
emissions to the air, discharges to surface waters,
and releases to land (including underground
injection wells).
For all toxic chemicals (except the dioxin and
dioxin-like compound category), do not enter the
values in Section 5 in gallons, tons, liters, or any
measure other than pounds. You must also enter the
values as whole numbers (do not use scientific
notation). Numbers following a decimal point are
not acceptable for toxic chemicals other than those
designated as PBT chemicals. For PBT chemicals,
facilities should report release and other waste
management quantities greater than 0.1 pound
(except the dioxin and dioxin-like compounds
category), provided the accuracy and the underlying
data on which the estimate is based supports this
level of precision.
For the dioxin and dioxin-like compounds category,
facilities should report at a level of precision
supported by the accuracy of the underlying data
and the estimation techniques on which the estimate
is based. For the dioxin and dioxin like compounds
chemical category, which has a reporting threshold
of 0.1 gram, facilities need only report all release
and other waste management quantities greater than
100 micrograms (i.e., 0.0001 grams). (See Example
12) Notwithstanding the numeric precision used
when determining reporting eligibility thresholds,
facilities should report on Form R to the level of
accuracy that their data supports, up to seven digits
to the right of the decimal. EPA's reporting software
and data management systems support data
precision up to seven digits to the right of the
decimal.

NA vs. a Numeric Value (e.g., Zero). Generally,
NA is applicable if the waste stream that contains or
contained the EPCRA Section 313 chemical is not
directed to the relevant environmental medium, or if
leaks, spills and fugitive emissions cannot occur. If
the waste stream that contains or contained the
EPCRA Section 313 chemical is directed to the
environmental medium, or if leaks, spills or fugitive
emissions can occur, NA should not be used, even if
treatment or emission controls result in a release of
zero. If the annual aggregate release of that chemical
was equal to or less than 0.5 pound, the value
reported is zero (unless the chemical is a listed PBT
chemical).
For Section 5.1, NA generally is not applicable for
volatile organic compounds (VOCs). For Section
5.5.4, NA generally would not be applicable,
recognizing the possibility of accidental spills or
leaks of the EPCRA Section 313 chemical.
An example that illustrates the use of NA vs. a
numeric value (e.g., zero) would be nitric acid
involved in a facility's processing activities. If the
facility neutralizes the wastes containing nitric acid
to a pH of 6 or above, then the facility reports a
release of zero for the EPCRA Section 313
chemical, not NA. Another example is when the
facility has no underground injection well, in which
case NA should be checked in Part II, Section 5.4.1
and 5.4.2 of Form R. Also, if the facility does not
landfill the acidic waste, NA should be checked in
Part II, Section 5.5.1.B of Form R.
All releases of the EPCRA Section 313 chemical to
the air must be classified as either stack or fugitive
emissions, and included in the total quantity
reported for these releases in Sections 5.1 and 5.2.
Instructions for columns A, B, and C follow the
discussions of Sections 5.1 through 5.5.
Toxics Release Inventory Reporting Forms and Instructions

-------
Part II Chemical Identification Information
5.1	Fugitive or Non-Point Air Emissions
Report the total of all releases of the EPCRA
Section 313 chemical to the air that are not released
through stacks, vents, ducts, pipes, or any other
confined air stream. You must include (1) fugitive
equipment leaks from valves, pump seals, flanges,
compressors, sampling connections, open-ended
lines, etc.; (2) evaporative losses from surface
impoundments and spills; (3) releases from building
ventilation systems; and (4) any other fugitive or
non-point air emissions. Engineering estimates and
mass balance calculations (using purchase records,
inventories, engineering knowledge or process
specifications of the quantity of the EPCRA Section
313 chemical entering product, hazardous waste
manifests, or monitoring records) may be useful in
estimating fugitive emissions. You should check the
NA box in Section 5.1 if you do not engage in
activities that result in fugitive or non-point air
emissions of this listed toxic chemical. For VOCs,
NA generally would not be applicable.
5.2	Stack or Point Air Emissions
Report the total of all releases of the EPCRA
Section 313 chemical to the air that occur through
stacks, confined vents, ducts, pipes, or other
confined air streams. You must include storage tank
emissions. Air releases from air pollution control
equipment would generally fall in this category.
Monitoring data, engineering estimates, and mass
balance calculations may help you to complete this
section. You should check the NA box in Section
5.2	if there are no stack air activities involving the
waste stream that contains or contained the EPCRA
Section 313 chemical.
5.3	Discharges to Receiving Streams or
Water Bodies
In Section 5.3 you are to enter all the names of the
streams or water bodies to which your facility
directly discharges the EPCRA Section 313
chemical on which you are reporting. Facilities may
enter releases to as many unique receiving streams
or water bodies as needed in TRI-MEweb. In
addition, you may also enter the 14-digit reach code,
which is a unique code that identifies a continuous
piece of surface water with similar hydrologic
characteristics, assigned to each receiving water
body by the United States Geographical Society's
(USGS) National Hydrography Dataset (NHD).
Note that reach data are not available for Alaska,
Guam, American Samoa and the Northern Mariana
Islands, so facilities located in these areas should
leave this field blank.
EPA maps all reported discharges to reaches for
purposes of its Risk Screening Environmental
Indicators (RSEI) model, Discharge Monitoring
Reports (DMR) Pollutant Loading Tool, and for
other analyses. Identifying your stream or water
body by entering a reach code in this section ensures
that EPA will map your discharges to the correct
reach.
In TRI-MEweb, facilities have the option of using
an interactive map interface to locate and identify
the receiving stream or water body to which the
chemical was released. TRI-MEweb will
automatically populate the appropriate reach code
field when you select your receiving water body on
the map provided in the user interface for this
section.
The name of the receiving stream or water body and
reach code may be manually entered by following
the Can't find or identify your stream or water
body on the map? link. In such a case, you should
report the name of the receiving stream or water
body and reach code as it appears on a discharge
permit or other appropriate documentation. If the
stream is not included in the NPDES permit or its
name is not identified in the NPDES permit, enter
the name of the off-site stream or water body by
which it is publicly known or enter the first publicly
named water body to which the receiving waters are
a tributary, if the receiving waters are unnamed. Do
not list a series of streams through which the
EPCRA Section 313 chemical flows. Be sure to
include all the receiving streams or water bodies that
receive stormwater runoff from your facility. Do not
enter names of streams to which off-site treatment
plants discharge.
You should check the NA box in Section 5.3 if there
are no discharges to receiving streams or water
bodies of the waste stream that contains or
contained the EPCRA Section 313 chemical (See
discussion of NA vs. a Numeric Value (e.g., Zero)
in the introduction of Section 5).
For each unique stream or water body, enter the
total annual amount of the EPCRA Section 313
chemical released from all discharge points at the
facility to each receiving stream or water body.
Include process outfalls such as pipes and open
trenches, releases from on-site wastewater treatment
systems, and the contribution from stormwater
runoff, if applicable (see instructions for column C
Toxics Release Inventory Reporting Forms and Instructions
48

-------
Part II. Chemical Identification Information
below). Do not include discharges to a POTW or
other off-site wastewater treatment facilities in this
section. These off-site transfers must be reported in
Part II, Section 6 of Form R. Wastewater analyses
and flowmeter data may provide the quantities you
will need to complete this section.
Discharges of listed acids (e.g., hydrogen fluoride,
nitric acid) may be reported as zero if the discharges
have been neutralized to pH 6 or above. If
wastewater containing a listed acid is discharged
below pH 6, then releases of the acid must be
reported. In this case, pH measurements may be
used to estimate the amount of mineral acid
released.
5.4-5.5 Disposal to Land On-site
Eight predefined subcategories for reporting
quantities released to land within the boundaries of
the facility (including underground injection) are
provided. Do not report land disposal at off-site
locations in this section. Consulting accident
histories and spill records may be useful when
preparing this section (e.g., release notification
reports required under Section 304 of EPCRA,
Section 103 of CERCLA, and accident histories
required under Sectionl 12(r)(7)(B)(ii) of the Clean
Air Act). Where relevant, you should check the NA
box in sections 5.4.1 through 5.5.3 if there are no
disposal activities for the waste stream that contains
or contained the EPCRA Section 313 chemical (See
discussion of NA vs. a Numeric Value (e.g., Zero)
in the introduction of Section 5). For 5.5.4, facilities
generally should report zero, recognizing the
potential for spills or leaks.
5.4.1	Class I Underground Injection Wells
Enter the total amount of the EPCRA Section 313
chemical that was injected into Class I wells at the
facility. Chemical analyses, injection rate meters,
and RCRA Hazardous Waste Generator Reports are
good sources for obtaining data that will be useful in
completing this section. You should check the NA
box in Section 5.4.1 if you do not inject the waste
stream that contains or contained the EPCRA
Section 313 chemical into Class I underground wells
(See discussion of NA vs. a Numeric Value (e.g.,
Zero) in the introduction of Section 5).
5.4.2	Class II- V Un dergroun d Injection Wells
Enter the total amount of the EPCRA Section 313
chemical that was injected into wells at the facility
other than Class I wells. Chemical analyses and
injection rate meters are good sources for obtaining
data that will be useful in completing this section.
You should check the NA box in Section 5.4.2 if
you do not inject the waste stream that contains or
contained the EPCRA Section 313 chemical into
Class II-V underground wells (See discussion of NA
vs. a Numeric Value (e.g., Zero) in the introduction
of Section 5).
5.5.1A RCRA Subtitle C Ian dfills
Enter the total amount of the EPCRA Section 313
chemical that was placed in RCRA Subtitle C
landfills. EPA has not required facilities to estimate
leaks from landfills because the amount of the
EPCRA Section 313 chemical has already been
reported as a release.
5.5. IB Other landfills
Enter the total amount of the EPCRA Section 313
chemical that was placed in landfills other than
RCRA Subtitle C landfills. EPA has not required
facilities to estimate leaks from landfills because the
amount of the EPCRA Section 313 chemical has
already been reported as a release.
5.5.2	land Treatment/Application Farming
Land treatment is a disposal method in which a
waste containing an EPCRA Section 313 chemical
is applied onto or incorporated into soil. While this
disposal method is considered a release to land, any
volatilization of EPCRA Section 313 chemicals into
the air occurring during the disposal operation must
not be included in this section but must be included
in the total fugitive air releases reported in Part II,
Section 5.1 of Form R.
5.5.3	Surface Impoundments
A surface impoundment is a natural topographic
depression, man-made excavation, or diked area
formed primarily of earthen materials (although
some may be lined with man-made materials), that
is designed to hold an accumulation of liquid wastes
or wastes containing free liquids. Examples of
surface impoundments are holding, settling, storage,
and elevation pits; ponds, and lagoons. If the pit,
pond, or lagoon is intended for storage or holding
without discharge, it would be considered to be a
surface impoundment used as a final disposal
method. A facility must determine, to the best of its
ability, the percentage of a volatile chemical, e.g.,
benzene, that is in waste sent to a surface
impoundment that evaporates during the reporting
year. The facility must report this as a fugitive air
emission in section 5.1. The balance should be
reported in either section 5.5.3A or 5.5.3B.
Quantities of the EPCRA Section 313 chemical
released to surface impoundments that are used
Toxics Release Inventory Reporting Forms and Instructions

-------
Part II Chemical Identification Information
merely as part of a wastewater treatment process
generally should not be reported in this section.
However, if an impoundment accumulates sludges
containing the EPCRA Section 313 chemical, you
must include an estimate in this section unless the
sludges are removed and otherwise disposed of (in
which case they must be reported under the
appropriate section of the form). For the purposes of
this reporting, storage tanks are not considered to be
a type of disposal and are not to be reported in this
section of Form R.
5.5. J/4 RCRA Subtitle C Surface Impoundments
Enter the total amount of the EPCRA Section 313
chemical that was placed in RCRA Subtitle C
surface impoundments.
5.5.3B Other Surface Impoundments
Enter the total amount of the EPCRA Section 313
chemical that was placed in surface impoundments
other than RCRA Subtitle C surface impoundments.
5.5.4 Other Disposal
Includes any amount of an EPCRA Section 313
chemical released to land that does not fit the
categories of landfills, land treatment, or surface
impoundment. This other disposal would include
any spills or leaks of EPCRA Section 313 chemicals
to land. For example, 2,000 pounds of benzene leaks
from an underground pipeline into the land at a
facility. Because the pipe was only a few feet from
the surface at the erupt point, 30 percent of the
benzene evaporates into the air. The 600 pounds
released to the air would be reported as a fugitive air
release (Part II, Section 5.1) and the remaining
1,400 pounds would be reported as a release to land,
other disposal (Part II, Section 5.5.4).
Section 5 Column A: Total Release
Only on-site releases of the EPCRA Section 313
chemical to the environment for the calendar year
are to be reported in this section of Form R. The
total on-site releases from your facility do not
include transfers or shipments of the EPCRA
Section 313 chemical from your facility for sale or
distribution in commerce, or of wastes to other
facilities for disposal, treatment, energy recovery, or
recycling (see Part II, Section 6 of these
Instructions). Both routine releases, such as fugitive
air emissions, and accidental or non-routine
releases, such as chemical spills, must be included
in your estimate of the quantity released.
Releases of Less Than 1,000 Pounds. For total
annual releases or off-site transfers of an EPCRA
Section 313 chemical from the facility of less than
1,000 pounds, the amount may be reported either as
an estimate or by using the range codes that have
been developed (range reporting in section 5 does
not apply to PBT chemicals). Do not enter a range
code and an estimate in the same box in column A.
The reporting range codes to be used are:
Code	Range (pounds)
A	1-10
B	11-499
C	500-999
Total annual on-site releases of an EPCRA Section
313 chemical from the facility of less than 1 pound
may be reported in one of several ways. You should
round the value to the nearest pound. If the estimate
is greater than 0.5 pound, you should either enter the
range code "A" for "1-10" or enter "1" in column A.
If the release is equal to or less than 0.5 pounds, you
may round to zero and enter "0" in column A.
Note that total annual releases of 0.5 pound or less
from the processing or otherwise use of an article
maintain the article status of that item. Thus, if the
only releases you have are from processing an
article, and such releases are equal to or less than
0.5 pound per year, you are not required to submit a
report for that EPCRA Section 313 chemical. The
0.5-pound release determination does not apply to
just a single article. It applies to the cumulative
releases from the processing or otherwise use of the
same type of article (e.g., sheet metal or plastic film)
that occurs over the course of the reporting year.
If you enter a range code in column A, some TRI
data tools used by the public will display the
midpoint of the range (i.e., 5, 250, or 750 lb).
Releases of 1,000 Pounds or More. For releases to
any medium that amount to 1,000 pounds or more
for the year, you must provide an estimate in pounds
per year in column A.
Data Precision. Generally, estimates provided need
not be reported to more than two significant figures.
This estimate should be in whole numbers.
However, facilities should report releases and other
waste management amounts at a level of precision
supported by the accuracy of the underlying data
and the estimation techniques on which the estimate
is based. If a facility's release or other management
calculations support reporting an amount that is
more precise than two significant digits, then the
facility should report that more precise amount.
Toxics Release Inventory Reporting Forms and Instructions
50

-------
Part II Chemical Identification Information
Calculating On-Site Releases. To provide the
release information in column A, EPCRA Section
313(g) (2) requires a facility to use readily available
data (including monitoring data) collected pursuant
to other provisions of law, or, where such data are
not readily available, "reasonable estimates" of the
amounts involved. If available data (including
monitoring data) are known to be non-
representative, facilities must make reasonable
estimates using the best readily available
information.
Reasonable estimates of the amounts released
should be made using published emission factors,
material balance calculations, or engineering
calculations. You may not use emission factors or
calculations to estimate releases if more accurate
data are available.
No additional monitoring or measurement of the
quantities or concentrations of any EPCRA Section
313 chemical released into the environment, or of
the frequency of such releases, beyond that required
under other provisions of law or regulation or as part
of routine plant operations, is required for the
purpose of completing Form R.
You must estimate the quantity (in pounds) of the
EPCRA Section 313 chemical or chemical category
that is released annually to each environmental
medium on-site. Include only the quantity of the
EPCRA Section 313 chemical in this estimate. If the
EPCRA Section 313 chemical present at your
facility was part of a mixture or other trade name
product, calculate only the releases of the EPCRA
Section 313 chemical, not the other components of
the mixture or other trade name product. If you are
only able to estimate the releases of the mixture or
other trade name product as a whole, you should
assume that the release of the EPCRA Section 313
chemical is proportional to its concentration in the
mixture or other trade name product. See Part 40,
Section 372.30(b) of the CFR for further
information on how to calculate the concentration
and weight of the EPCRA Section 313 chemical in
the mixture or other trade name product.
If you are reporting an EPCRA Section 313
chemical category listed in Table II of these
instructions rather than a specific EPCRA Section
313 chemical, you must combine the release data for
all chemicals in the EPCRA Section 313 chemical
category (e.g., all listed members of certain glycol
ethers or all listed members of chlorophenols) and
report the aggregate amount for that EPCRA Section
313 chemical in that category separately. For
example, if your facility releases 3,000 pounds per
year of 2-chlorophenol, 4,000 pounds per year of 3-
chlorophenol, and 4,000 pounds per year of 4-
chlorophenol to air as fugitive emissions, you must
report that your facility releases 11,000 pounds per
year of chlorophenols to air as fugitive emissions in
Part II, Section 5.1.
For aqueous ammonia solutions, releases must be
reported based on 10 percent of total aqueous
ammonia. Ammonia evaporating from aqueous
ammonia solutions is considered to be anhydrous
ammonia; therefore, 100 percent of the anhydrous
ammonia should be reported if it is released to the
environment.
For dissociable nitrate compounds, release estimates
should be based on the weight of the nitrate only.
For metal category compounds (e.g., chromium
compounds), report releases of only the parent
metal. For example, a user of various inorganic
chromium salts would report the total chromium
released regardless of the chemical compound and
exclude any contribution to mass made by the other
portion of the compound.
Section 5 Column B: Basis of Estimate
For each release and otherwise managed waste
estimate (Sections 5 & 6), you are required to
indicate the principal method used to determine the
amount of release and otherwise managed waste
reported. You should enter a letter code identifying
the method that applies to the largest portion of the
total estimated release and otherwise managed waste
quantity.
The codes are as follows:
Ml Estimate is based on continuous monitoring
data or measurements for the EPCRA Section
313 chemical.
M2 Estimate is based on periodic or random
monitoring data or measurements for the
EPCRA Section 313 chemical.
C Estimate is based on mass balance
calculations, such as calculation of the amount
of the EPCRA Section 313 chemical in
streams entering and leaving process
equipment.
El Estimate is based on published emission
factors, such as those relating release quantity
to through-put or equipment type (e.g., air
emission factors).
E2 Estimate is based on-site specific emission
factors, such as those relating release quantity
Toxics Release Inventory Reporting Forms and Instructions
51

-------
Part II Chemical Identification Information
to through-put or equipment type (e.g., air
emission factors).
O Estimate is based on other approaches such as
engineering calculations (e.g., estimating
volatilization using published mathematical
formulas) or best engineering judgment. This
would include applying estimated removal
efficiency to a waste stream, even if the
composition of the stream before treatment
was fully identified through monitoring data.
For example, if 40 percent of stack emissions of the
reported EPCRA Section 313 chemical were derived
using source testing data, 30 percent by mass
balance, and 30 percent by published chemical-
specific emission factors, you should enter the code
letter "M2" for periodic or random emission
monitoring.
If the monitoring data, mass balance, or emission
factor used to estimate the release is not specific to
the EPCRA Section 313 chemical being reported,
the form should identify the estimate based on other
methods of estimation (O).
If a mass balance calculation yields the flow rate of
a waste, but the quantity of reported EPCRA Section
313 chemical in the waste is based on solubility
data, you should report "O" because engineering
calculations were used as the basis of estimate of the
quantity of the EPCRA Section 313 chemical in the
waste.
If the concentration of the EPCRA Section 313
chemical in the waste was measured by continuous
emissions monitoring equipment and the flow rate
of the waste was determined by mass balance, then
the primary basis of the estimate should be
"continuous emission monitoring" (Ml). Even
though a mass balance calculation also contributed
to the estimate, "continuous emission monitoring"
should be indicated because monitoring data were
used to estimate the concentration of the chemical in
waste.
Mass balance (C) should only be indicated if it is
directly used to calculate the mass (weight) of
EPCRA Section 313 chemical released. Monitoring
data should be indicated as the basis of estimate
only if the EPCRA Section 313 chemical
concentration is measured in the waste. Monitoring
data should not be indicated, for example, if the
monitoring data relate to a concentration of the
EPCRA Section 313 chemical in other process
streams within the facility.
It is important to realize that the accuracy and
proficiency of release estimation will improve over
time. However, submitters are not required to use
new emission factors or estimation techniques to
revise previous Form R submissions.
Section 5 Column C: Percent from Stormwater
This column relates only to Section 5.3 - discharges
to receiving streams or water bodies. If your facility
has monitoring data on the amount of the EPCRA
Section 313 chemical in stormwater runoff
(including unchanneled runoff), you must include
that quantity of the EPCRA Section 313 chemical in
your water release in column A and indicate the
percentage of the total quantity (by weight) of the
EPCRA Section 313 chemical contributed by
stormwater in column C (Section 5.3C).
If your facility has monitoring data on the EPCRA
Section 313 chemical and an estimate of flow rate,
you must use these data to determine the percent
stormwater.
If you have monitored stormwater but did not detect
the EPCRA Section 313 chemical, enter zero in
column C. If your facility has no stormwater
monitoring data for the chemical, you should check
the NA box.
If your facility does not have periodic measurements
of stormwater releases of the EPCRA Section 313
chemical, but has submitted chemical-specific
monitoring data in permit applications, then these
data must be used to calculate the percent
contribution from stormwater. One way to calculate
the flow rates from stormwater runoff is the
Rational Method. In this method, flow rates, Q, can
be estimated by multiplying the land area of the
facility, A, by the runoff coefficient, C, and then
multiplying that figure by the annual rainfall
intensity, I (i.e., Q = A x C x I). The rainfall
intensity, I, is specific to the geographical area of
the country where the facility is located, and may be
obtained from most standard engineering manuals
for hydrology. The flow rate, Q, will have
volumetric dimensions per unit time, and will have
to be converted to units of pounds per year. The
runoff coefficient represents the fraction of rainfall
that does not seep into the ground but runs off as
stormwater. The runoff coefficient is directly related
to how the land in the drainage area is used. (See
table below).

You should choose the most appropriate runoff coefficient for your site or calculate a weighted-average
coefficient, which takes into account different types of land use at your facility:
Weighted-average runoff coefficient =
(Area 1 % of total)(Cl) + (Area 2 % of total)(C2) + (Area 3 % of total)(C3) + ... + (Area i % of total)(Ci)
where
Ci = runoff coefficient for a specific land use of Area i.

Part II Chemical Identification Information
Section 6. Transfer(s) of the Toxic
Chemical in Wastes to Off-Site
Locations (Form R)
You must report in this section the total annual
quantity of the EPCRA Section 313 chemical in
wastes sent to any off-site facility for the purposes
of disposal, treatment, energy recovery, or
recycling. Report the total amount of the EPCRA
Section 313 chemical transferred off-site after any
on-site waste treatment, recycling, or removal is
completed.
For all toxic chemicals (except the dioxin and
dioxin-like compounds category), do not enter the
values in Section 6 in gallons, tons, liters, or any
measure other than pounds. You must also enter the
values as whole numbers. Numbers following a
decimal point are not acceptable for toxic chemicals
other than those designated as PBT chemicals. For
PBT chemicals, facilities should report release and
other waste management quantities greater than 0.1
pound (except the dioxin and dioxin-like
compounds category) provided the accuracy and the
underlying data on which the estimate is based
supports this level of precision.
Dioxin and dioxin-like compounds category.
Facilities should report at a level of precision
supported by the accuracy of the underlying data
and the estimation techniques on which the estimate
is based. Notwithstanding the numeric precision
used when determining reporting eligibility
thresholds, facilities should report on Form R to the
level of accuracy that their data supports, up to
seven digits to the right of the decimal. TRI-MEweb
and EPA's data management systems support data
precision to seven digits to the right of the decimal.
The smallest quantity that needs to be reported on
the Form R for the dioxin and dioxin-like
compounds category is 0.0001 grams (see Example
12).
NA vs. a Numeric Value (e.g., Zero). You must
enter a numeric value if you transfer an EPCRA
Section 313 chemical to a Publicly Owned
Treatment Works (POTW) or transfer wastes
containing that toxic chemical to other off-site
locations. If the aggregate amount transferred was
less than 0.5 pound, then you should enter zero
(unless the chemical is listed as a PBT chemical).
Also report zero for transfers of listed mineral acids
(i.e., hydrogen fluoride and nitric acid) if they have
been neutralized to a pH of 6 or above prior to
discharge to a POTW; do not check NA.
However, if you do not discharge wastewater
containing the reported EPCRA Section 313
chemical to a POTW, you should check the "Not
Applicable" box in Section 6.1. If you do not ship or
transfer wastes containing the reported EPCRA
Section 313 chemical to other off-site locations, you
should check the "Not Applicable" box in Section
6.2. In TRI-MEweb, users may enter as many
unique transfers as needed.
6.1 Discharges to Publicly Owned Treatment
Works
In Section 6.1, facilities using TRI-MEweb can
click "Add New POTW" to use a search tool to
search POTWs by location or NPDES ID. If the
receiving POTW cannot be identified using the
search, the user may enter the POTW information
manually by clicking "Enter New POTW," and
then provide the receiving POTWs' name and
address.
Facilities should report for each POTW to which the
facility discharges or otherwise transfers wastewater
containing the reported EPCRA Section 313
chemical. The most common transfers of this type
will be conveyances of the toxic chemical in facility
wastewater through underground sewage pipes;
however, materials may also be trucked or
transferred via some other direct methods to a
POTW.
Facilities report the total quantity transferred to each
POTW and the basis of estimate for the total
quantity reported in Section 6.1.[ ]A or Section
6.1.[ ]B (for columns A and B, respectively).
When you enter quantities in Section 6.1 in TRI-
MEweb, you will be prompted for information on
the final disposition of the off-site transfer for use in
Section 8 calculations (see instructions for Section
8). Removal and destruction rates for toxic
chemicals sent to POTW (based on experimental
and estimated data compiled by EPA) are pre-
loaded into TRI-MEweb for this purpose but may be
overridden if you have better information on the
final disposition of the chemical readily available.
If you do not discharge wastewater containing the
reported EPCRA Section 313 chemical to a POTW,
enter NA in the box in Section 6.1. (See discussion
of NA vs. a Numeric Value (e.g., Zero) in the
introduction of Section 6).

6.1.[ ]A. Quantity Transferred to Each POTW
Enter the total amount, in pounds, of the reported
EPCRA Section 313 chemical that is contained in
the wastewaters transferred to each POTW. Do not
enter the total poundage of the wastewaters. If the
total amount transferred is less than 1,000 pounds,
you may report a range by entering the appropriate
range code (range reporting in section 6.1.[ ]_A.
does not apply to PBT chemicals). The following
reporting range codes are to be used:
Code	Reporting Range (in pounds)
A	1-10
B	11-499
C	500-999
If you enter a range code in column A, some TRI
data tools used by the public will display the
midpoint of the range (i.e., 5, 250, or 750 lb).
6. l.[ ]B	Basis of Estimate
You must identify the basis for your estimate of the
total quantity of the reported EPCRA Section 313
chemical in the wastewater transferred to each
POTW. You should enter one of the following letter
codes that applies to the method by which the
largest percentage of the estimate was derived.
Ml Estimate is based on continuous monitoring
data or measurements for the EPCRA Section
313 chemical.
M2 Estimate is based on periodic or random
monitoring data or measurements for the
EPCRA Section 313 chemical.
C Estimate is based on mass balance
calculations, such as calculation of the amount
of the EPCRA Section 313 chemical in
streams entering and leaving process
equipment.
El Estimate is based on published emission
factors, such as those relating release quantity
to through-put or equipment type (e.g., air
emission factors).
E2 Estimate is based on-site specific emission
factors, such as those relating release quantity
to through-put or equipment type (e.g., air
emission factors).
O Estimate is based on other approaches such as
engineering calculations (e.g., estimating
volatilization using published mathematical
formulas) or best engineering judgment. This
would include applying estimated removal
efficiency to a waste stream, even if the
composition of the stream before treatment
was fully identified through monitoring data.
If you estimate the total quantities transferred of an
EPCRA Section 313 chemical for one POTW using
more than one calculation method, you should
report the basis of estimate that was used to
determine the largest percentage of the EPCRA
Section 313 chemical that was transferred.
6.2 Transfers to Other Off-Site Locations
In Section 6.2, facilities using TRI-MEweb can
click "New Location" to access a form to search
off-site transfer locations by location or RCRA ID.
to which the facility ships or transfers wastes
containing the reported EPCRA Section 313
chemical for the purposes of disposal, treatment,
energy recovery, or recycling. If the receiving other
off-site location cannot be identified using the
search, the user may enter the off-site location
information clicking "Enter New Location," and
then indicating the receiving other off-site locations'
name and address. Reporters must also indicate if
the receiving location is under the control of the
reporting facility or parent company.
In general, a RCRA ID Number (also called an EPA
Identification Number) will commonly be found on
the Uniform Hazardous Waste Manifest, which is
required by RCRA regulations for the transfer of
hazardous wastes. However, please note that an off-
site transfer of a non-hazardous waste containing a
TRI chemical may be received by a facility with a
RCRA ID. If the receiving facility's RCRA ID is
known, even if it is not associated with the waste
transfer that you are initiating, it should be provided
in Section 6.2. The purpose of the RCRA ID
number is for the identification of the off-site
transfer facility and not just to indicate a hazardous
waste transfer. If you ship or transfer wastes
containing an EPCRA Section 313 chemical and the
off-site location does not have an EPA Identification
Number, enter NA in the box for the off-site
location EPA Identification Number.
Specifically for other off-site transfers, facilities
must also report the type of disposal, treatment,
energy recovery, or recycling methods used by the
off-site location for the reported EPCRA Section
313 chemical (see Section 6.2 Column C). If
appropriate, you must report multiple activities for
each off-site location. For example, if your facility
sends a reported EPCRA Section 313 chemical in a
single waste stream to an off-site location where
some of the EPCRA Section 313 chemical is to be
recycled while the remainder of the quantity
transferred is to be treated, you must report both the
Toxics Release Inventory Reporting Forms and Instructions
56

-------
Part II. Chemical Identification Information
waste treatment and recycle activities, along with
the quantity associated with each activity.
If your facility transfers an EPCRA Section 313
chemical to an off-site location and that off-site
location performs more than four activities on that
chemical, multiple transfers may be listed by
clicking "+ Add Transfer."
If you do not ship or transfer wastes containing the
EPCRA Section 313 chemical to other off-site
locations, you should check the Not Applicable box
in Section 6.2, "Transfers to Other Off-Site
Locations."
If you ship or transfer the reported EPCRA Section
313 chemical in wastes to another country, you do
not need to report a RCRA ID for that waste. You
should check "Not Applicable" for the RCRA ID
field. Enter the location information for the non-
U.S. facility including: location name, address, city,
province, country, and postal code. TRI-MEweb
provides a dropdown for selecting countries and
their Federal Information Processing Standards
(FIPS) codes. There is nothing to enter in the state
field.
6.2a Column A: Total Transfers
For each off-site location, enter the total amount, in
pounds (in grams for dioxin and dioxin-like
compounds), of the EPCRA Section 313 chemical
that is contained in the waste transferred to that
location. Do not enter the total quantities of the
waste. If you do not ship or transfer wastes
containing the EPCRA Section 313 chemical to
other off-site locations, you should enter NA (See
discussion of NA vs. a Numeric Value (e.g., Zero)
in the introduction of Section 6) in the box for the
off-site location's EPA Identification Number
(defined in 40 CFR 260.10 and therefore commonly
referred to as the RCRA ID Number).
If the total amount transferred is less than 1,000
pounds, you may report a range by entering the
appropriate range code (range reporting in section
6.2 does not apply to PBT chemicals). The
following reporting range codes are to be used:
Code	Reporting Range (in pounds)
A	1-10
B	11-499
C	500-999
Note that if you enter a range code in column A,
some TRI data tools used by the public will display
the midpoint of the range (i.e., 5, 250, or 750 lb).
If you transfer the EPCRA Section 313 chemical in
wastes to an off-site facility for distinct and multiple
purposes, you must report those activities for each
off-site location, along with the quantity of the
reported EPCRA Section 313 chemical associated
with each activity. For example, your facility
transfers a total of 15,000 pounds of toluene to an
off-site location that will use 5,000 pounds for the
purposes of energy recovery, will enter 7,500
pounds into a recovery process, and will dispose of
the remaining 2,500 pounds. These quantities and
the associated activity codes must be reported
separately in Section 6.2. (See Figure 6 for a
hypothetical Section 6.2 completed for two off-site
locations, one of which receives the transfer of
15,000 pounds of toluene as detailed.) If you have
fewer than four total transfers in Section 6.2
Column A (see examples in Figure 6), an NA should
be placed in Column A of the first unused row to
indicate the termination of the sequence. If all four
rows are used, there is no need to terminate the
sequence. If there are more than four total transfers,
re-enter the name of the off-site location, address,
etc. in the next row (6.2.2) and then you should
enter NA when the sequence has terminated if there
are fewer than 8 (i.e. anytime there are fewer than 4
transfers listed in a Section 6.2 block, an NA should
be used to terminate the sequence).
Do not double or multiple count amounts transferred
off-site. For example, when a reported EPCRA
Section 313 chemical is sent to an off-site facility
for sequential activities, you should report the final
disposition of the toxic chemical.

You must identify the basis for your estimates of the
quantities of the reported EPCRA Section 313
chemical in waste transferred to each off-site
location. Enter one of the following letter codes that
applies to the method by which the largest
percentage of the estimate was derived.
Ml Estimate is based on continuous monitoring
data or measurements for the EPCRA Section
313 chemical.
M2 Estimate is based on periodic or random

C Estimate is based on mass balance
calculations, such as calculation of the

formulas) or best engineering judgment. This
would include applying an estimated removal
efficiency to a waste stream, even if the
composition of the stream before treatment
was fully identified through monitoring data.
6.2c Column C: Type of Waste Management:
Disposal/ Treatment/Energy
Recovery/Recycling
You should enter one of the following M codes to
identify the type of disposal, treatment, energy
recovery, or recycling methods used by the off-site
location for the reported EPCRA Section 313
chemical. You must use separate transfers and codes
for a single location when distinct quantities of the
reported EPCRA Section 313 chemical are subject
to different waste management activities, including
disposal, treatment, energy recovery, or recycling.
You must use the code that represents the ultimate
disposition of the chemical.
If the EPCRA Section 313 chemical is sent off-site
for further direct reuse (e.g., an EPCRA Section 313
chemical in used solvent that will be used as
lubricant at another facility) and does not undergo a
waste management activity (i.e., release (including
disposal), treatment, energy recovery, or recycling
(recovery)) prior to that reuse, it need not be
reported in section 6.2 or section 8.
Incineration vs. Energy Recovery
You must distinguish between incineration which is
waste treatment, and legitimate energy recovery. For
you to claim that a reported EPCRA Section 313
chemical sent off-site is used for the purposes of
energy recovery and not for treatment for
destruction, the EPCRA Section 313 chemical must
have a significant heating value and must be
combusted in an energy recovery unit such as an
industrial boiler, furnace, or kiln. In a situation
where the reported EPCRA Section 313 chemical is
in a waste that is combusted in an energy recovery
unit, but the EPCRA Section 313 chemical does not
have a significant heating value, e.g., CFCs, you
should use code M54, Incineration/Insignificant
Fuel Value, to indicate that the EPCRA Section 313
chemical was incinerated in an energy recovery unit
but did not contribute to the heating value of the
waste.
Metals and Metal Category Compounds
Metals and metal category compounds will be
managed in waste either by being released
(including disposed of) or by being recycled.
Remember that the release and other waste
management information that you report for metal
category compounds will be the total amount of the
parent metal released or recycled and NOT the
whole metal category compound. The metal has no
heat value and thus cannot be combusted for energy
recovery and cannot be treated because it cannot be
destroyed. Thus, transfers of metals and metal
category compounds for further waste management
should be reported as either a transfer for recycling
or a transfer for disposal. The applicable waste
management codes for transfers of metals and metal
category compounds for recycling are M24, metals
recovery, M93, waste broker - recycling, or M26,
other reuse/recovery. Applicable codes for transfers
for disposal include M10, M41, M62, M64, M65,
M66, M67, M73, M79, M81, M82, M90, M94, and
M99. These codes are for off-site transfers for
further waste management in which the waste
stream may be treated but the metal contained in the

Section 7A: On-Site Waste Treatment
Methods and Efficiency
Most of the chemical-specific information required
by EPCRA Section 313 that is reported on Form R
is specific to the EPCRA Section 313 chemical
rather than the waste stream containing the EPCRA
Section 313 chemical. However, EPCRA Section
313 does require that waste treatment methods
applied on-site to waste streams that contain the
EPCRA Section 313 chemical be reported. This
information is reportable regardless of whether the
facility actively applies treatment or the treatment of
the waste stream occurs passively. This information
is collected in Section 7A of Form R.
In Section 7A, you must provide the following
information if you treat waste streams containing
the reported EPCRA Section 313 chemical on-site:
(a)	The general waste stream types containing the
EPCRA Section 313 chemical being reported;
(b)	The waste treatment method(s) or sequence
used on all waste streams containing the
EPCRA Section 313 chemical; and
(c)	The efficiency of each waste treatment
method or waste treatment sequence in
destroying or removing the EPCRA Section
313 chemical.
When entering on-site treatment data in TRI-
MEweb, use a separate waste treatment profile in
Section 7A for each general waste stream type. Each
profile contains the general waste stream type (7A
Column a) and all waste treatment methods
associated with that stream (7A Column b). In TRI-
MEweb, each profile treatment stream is assigned a
name. Each waste treatment profile generated for a
facility is available to be used for other forms from
the same facility for the same reporting year. Report
only information about treatment of waste streams
at your facility, not information about off-site waste
treatment.
For each waste treatment profile, provide the
appropriate waste treatment efficiency code (7A
Column c) for that chemical.
TRI-MEweb may also simultaneously collect total
quantities treated on-site for the current reporting
year for this chemical (see Section 8.6).
If you do not perform on-site treatment of waste
streams containing the reported EPCRA Section 313
chemical, check the "Not Applicable" box for
Section 7A.
7A Column a: General Waste Stream
For each waste treatment method, indicate the type
of waste stream containing the EPCRA Section 313
chemical that is treated. Select the letter code that
corresponds to the general waste stream type:
A Gaseous (gases, vapors, airborne particulates)
W Wastewater (aqueous waste)
L Liquid waste streams (non-aqueous waste)
S Solid waste streams (including sludges and
slurries)
If a waste is a combination of water and organic
liquid and the organic content is less than 50
percent, report it as a wastewater (W). Slurries and
sludges containing water should be reported as solid
waste if they contain appreciable amounts of
dissolved solids, or solids that may settle, such that
the viscosity or density of the waste is considerably
different from that of process wastewater.
7A Column b: Waste Treatment Method(s)
Sequence
Enter the appropriate waste treatment code from the
list below for each on-site waste treatment method
used on a waste stream containing the EPCRA
Section 313 chemical, regardless of whether the
waste treatment method actually removes the
specific EPCRA Section 313 chemical being
reported. Waste treatment methods must be reported
for each type of waste stream being treated (i.e.,
gaseous waste streams, aqueous waste streams,
liquid non-aqueous waste streams, and solids).
Except for the air emission treatment codes, the
waste treatment codes are not restricted to any
medium.
Waste streams containing the EPCRA Section 313
chemical may have a single source or may be
aggregates of many sources. For example, process
Toxics Release Inventory Reporting Forms and Instructions

-------
Part II Chemical Identification Information
water from several pieces of equipment at your
facility may be combined prior to waste treatment.
Report waste treatment methods that apply to the
aggregate waste stream, as well as waste treatment
methods that apply to individual waste streams. If
your facility treats various wastewater streams
containing the EPCRA Section 313 chemical in
different ways, the different waste treatment
methods must be listed separately.
If your facility has several pieces of equipment
performing a similar service in a waste treatment
sequence, you may combine the reporting for such
equipment. It is not necessary to enter four codes to
cover four scrubber units, for example, if all four are
treating waste streams of similar character (e.g.,
sulfuric acid mist emissions), have similar influent
concentrations, and have similar removal
efficiencies. If, however, any of these parameters
differs from one unit to the next, each scrubber
should be listed separately.

7A Column c: Waste Treatment Efficiency
Estimate
In the space provided, enter the range code, based
upon the codes listed below, indicating the
percentage of the EPCRA Section 313 chemical
removed from the waste stream through destruction,
biological degradation, chemical conversion, or
physical removal. The waste treatment efficiency
(expressed as a range of percent removal) represents
the percentage of the EPCRA Section 313 chemical
destroyed or removed (based on amount or mass),
not merely changes in volume or concentration of
the EPCRA Section 313 chemical in the waste
stream. The efficiency, which can reflect the overall
removal from sequential treatment methods applied
to the general waste stream, refers only to the
percent destruction, degradation, conversion, or
removal of the EPCRA Section 313 chemical from
the waste stream; it does not refer to the percent
conversion or removal of other constituents in the
waste stream. The efficiency also does not refer to
the general efficiency of the treatment method for
any waste stream. For some waste treatment
methods, the percent removal will represent removal
by several mechanisms, as in an aeration basin,
where an EPCRA Section 313 chemical may
evaporate, biodegrade, or be physically removed
from the sludge.
Toxics Release Inventory Reporting Forms and Instructions
66
-------
Part II Chemical Identification Information
Percent removal can be calculated as follows:
a-ei x 100%
i
where:
I = amount of the EPCRA Section 313 chemical in
the influent waste stream (entering the waste
treatment step or sequence) and
E = amount of the EPCRA Section 313 chemical in
the effluent waste stream (exiting the waste
treatment step or sequence).
Calculate the amount of the EPCRA Section 313
chemical in the influent waste stream by multiplying
the concentration (by weight) of the EPCRA Section
313 chemical in the waste stream by the total
amount or weight of the waste stream. In most
cases, the percent removal compares the treated
effluent to the influent for the particular type of
waste stream. For solidification of wastewater, the
waste treatment efficiency can be reported as code
El (greater than 99.9999 percent) if no volatile
EPCRA Section 313 chemicals were removed with
the water or evaporated into the air. Percent removal
does not apply to incineration because the waste
stream, such as wastewater or liquids, may not exist
in a comparable form after waste treatment and the
purpose of incineration as a waste treatment is to
destroy the EPCRA Section 313 chemical by
converting it to carbon dioxide and water or other
byproducts. In cases where the EPCRA Section 313
chemical is incinerated, the percent efficiency must
be based on the amount of the EPCRA Section 313
chemical destroyed or combusted, except for metals
or metal category compounds. In the cases in which
a metal or metal category compound is incinerated,
the efficiency is reported as code E6 (equal to or
greater than 0 percent, but less than or equal to 50
percent).
Similarly, an efficiency of zero must be reported for
any waste treatment method(s) that does not destroy,
chemically convert or physically remove the
EPCRA Section 313 chemical from the waste
stream.
For metal category compounds, the calculation of
the reportable concentration and waste treatment
efficiency must be based on the weight of the parent
metal, not on the weight of the metal compound.
Metals are not destroyed, only physically removed
or chemically converted from one form into another.
The waste treatment efficiency reported must
represent only physical removal of the parent metal
from the waste stream (except for incineration), not
the percent chemical conversion of the metal
compound. If a listed waste treatment method
converts but does not remove a metal (e.g.,
chromium reduction), the method must be reported
with a waste treatment efficiency of code E6 (equal
to or greater than 0 percent, but less than or equal to
50 percent.
EPCRA Section 313 chemicals that are strong
mineral acids neutralized to a pH of 6 or above are
considered treated at 100 percent efficiency.
When calculating waste treatment efficiency,
EPCRA Section 313(g)(2) requires a facility to use
readily available data (including monitoring data)
collected pursuant to other provisions of law, or,
where such data are not readily available,
"reasonable estimates" of the amounts involved.
Waste Treatment Efficiency Range Codes:
El =
greater than 99.9999%
E2 =
greater than 99.99%, but less than or equal

to 99.9999%
E3 =
greater than 99%, but less than or equal to

E6 =

Section 7B: On-site Energy Recovery
Processes
In Section 7B, you must indicate the on-site energy
recovery methods used on the reported EPCRA
Section 313 chemical.
EPA considers an EPCRA Section 313 chemical to
be combusted for energy recovery if the toxic
chemical has a significant heat value and is
combusted in an energy recovery device. If a
reported EPCRA Section 313 chemical is
incinerated on-site but does not contribute energy to
the process (e.g., chlorofluorocarbons), it must be
considered waste treated on-site and reported in
Section 7A. Metals and metal category compounds
cannot be combusted for energy recovery and
should NOT be reported in this section. Do not
include the combustion of fuel oils, such as fuel oil
#6, in this section. Energy recovery may take place
only in an industrial kiln, furnace, or boiler.

Section 8. Source Reduction and
Waste Management (Form R)
This section includes the data elements mandated by
Section 6607 of the Pollution Prevention Act of
1990 (PPA).
In Section 8, you must provide information about
source reduction activities and quantities of the
EPCRA Section 313 chemicals managed as waste.
For all appropriate questions, report only the
quantity, in pounds, (or, for the dioxin and dioxin-
like compounds category, grams) of the reported
EPCRA Section 313 chemical itself. Do not include
the weight of water, soil, or other waste constituents.
When reporting on the metal category compounds,
you should report only the amount of the metal
portion of the compound as you do when estimating
release amounts.
Sections 8.1 through 8.9 must be completed for each
EPCRA Section 313 chemical. Section 8.10 must be
completed only if a source reduction activity was
newly implemented specifically (in whole or in part)
for the reported EPCRA Section 313 chemical
during the reporting year. Section 8.11 allows you to
submit additional optional information on source
reduction, recycling, or pollution control activities
implemented for the reported EPCRA Section 313
chemical at any time at your facility. For example,
you may provide additional information on new or
on-going practices.
Sections 8.1 through 8.7 require reporting of
production-related waste management quantities for
the current reporting year, the prior year, and
quantities anticipated in both the first year
immediately following the reporting year and the
second year following the reporting year (future
estimates).
Do not enter the values in Section 8 in gallons, tons,
liters, or any measure other than pounds (or, for the
dioxin and dioxin-like compounds category, grams).
For non-PBT chemicals, you must generally enter
the values as whole numbers; numbers following a
decimal point are not acceptable for non-PBT
chemicals except as noted in the instructions for
Sections 8.1c-d and 8.7. For PBT chemicals (except
the dioxin and dioxin-like compounds category),
facilities should report release and other waste
management quantities greater than 0.1 pound
provided the accuracy and the underlying data on
which the estimate is based supports this level of
precision.
For the dioxin and dioxin-like compounds category,
facilities should report at a level of precision
supported by the accuracy of the underlying data
and the estimation techniques on which the estimate
is based. However, the smallest quantity that need
be reported on the Form R for the dioxin and dioxin-
like compounds category is 0.0001 grams (see
Example 12). Notwithstanding the numeric
precision used when determining reporting
eligibility thresholds, facilities should report on
Form R to the level of accuracy that their data
supports, up to seven digits to the right of the
decimal. EPA's reporting software and data
management systems support data precision to
seven digits to the right of the decimal.
NA vs. a Numeric Value (e.g., Zero). You should
enter a numeric value in the relevant sections of
Section 8 if your facility has released, treated,
combusted for energy recovery or recycled any
quantity of an EPCRA Section 313 chemical during
the reporting year. If the aggregate quantity of that
toxic chemical was equal to or less than 0.5 pound
for a particular waste management method, you
should enter the value zero (unless the chemical is a
PBT chemical) in the relevant section. In the case
of PBTs (excluding dioxin) if the aggregate quantity
of the toxic chemical is equal to or less than 0.1
pound for a particular waste management method,
you should enter the value zero in the relevant
section. For dioxin, if the aggregate quantity is
equal to or less than .0001 grams for a particular
waste management method, you should enter the
value zero in the relevant section. For both PBTs
and dioxin, the accuracy of the underlying data on
which the estimate is based must support the
specified level of precision in order to round to zero.
However, if there has been no on-site or off-site
treatment, combustion for energy recovery, or
recycling of the waste stream containing the EPCRA
Section 313 chemical, then you should enter NA in
the relevant section. (Note: for metals and metal
category compounds, you should enter NA in
Sections 8.2, 8.3, 8.6 and 8.7, as treatment and
combustion for energy recovery generally are not
applicable waste management methods for metals
and metal compounds). For Section 8.1b, NA
generally is not applicable recognizing the potential
for spills, leaks, or fugitive emissions of the EPCRA
Section 313 chemical. You should enter NA in
Section 8.8 if there were no remedial actions,
catastrophic events such as earthquakes, fires, or
floods or one-time events not associated with
normal or routine production processes for that toxic
Toxics Release Inventory Reporting Forms and Instructions
71
-------
Part II Chemical Identification Information
chemical. If there was a catastrophic event at your
facility, but you were able to prevent any releases
from occurring, then enter zero in Section 8.8.
Relationship to Other Laws
The reporting categories for quantities recycled,
used for energy recovery, treated, and disposed of
apply to completing Section 8 of Form R as well as
to the rest of Form R. These categories are to be
used only for TRI reporting. They are not intended
for use in determining, under the Resource
Conservation and Recovery Act (RCRA) Subtitle C
regulations, whether a secondary material is a waste
when recycled. These categories also do not apply to
the information that may be submitted in the
Biennial Report required under RCRA. In addition,
these categories do not imply any future redefinition
of RCRA terms and do not affect EPA's RCRA
authority or authority under any other statute
administered by EPA.
Differences in terminology and reporting
requirements for EPCRA Section 313 chemicals
reported on Form R and for hazardous wastes
regulated under RCRA occur because EPCRA and
the PPA focus on specific chemicals, while the
RCRA regulations and the Biennial Report focus on
waste streams that may include more than one
chemical. For example, assume that a RCRA
hazardous waste containing an EPCRA Section 313
chemical is recycled to recover certain constituents
of that waste, but not the toxic chemical reported
under EPCRA Section 313. The EPCRA Section
313 chemical simply passes through the recycling
process and remains in the residual from the
recycling process, which is disposed of. While the
waste may be considered recycled under RCRA, for
TRI purposes, the EPCRA Section 313 chemical
constituent would be considered to be disposed of
(as part of the residual from the recycling process).
An EPCRA Section 313 chemical or an EPCRA
Section 313 chemical in a mixture that is a waste
under RCRA must be reported in Sections 8.1
through 8.8.

EPA expects reasonable future quantity estimates
using a logical basis. Information available at the
facility to estimate quantities of the chemical
expected during these years include (but are not
limited to) planned source reduction activities,
market projections, expected contracts, anticipated
new product lines, company growth projections, and
production capacity figures.
Quantities Reportable in Sections 8.1 - 8.7
Section 8 of Form R uses data collected to complete
Part II, Sections 5 through 7. For this reason,
Section 8 should be completed last. The relationship
between Sections 5, 6, and 8.8 to Sections 8.1, 8.3,
8.5, and 8.7 are summarized below in a table
(Relationship between Form R Sections 8.1-8.7 and
Sections 5, 6 and 7) and explicitly described in
equation form in the text. EPA recommends that you
use these equations to complete Sections 8.1, 8.3,
8.5, and 8.7 for the current year and discourages
rounding. For Column B (current year), TRI-
MEweb will use these equations to complete these
Sections automatically.
Note on Equations. Where an equation includes a
value followed by a parenthetical, this means that
the equation is referring only to the portion of that
value described by the parenthetical. For example,
"Section 6.2 (recycling)" refers to the portion of the
value for Section 6.2 that is recycled, while
"Section 6.2 (treatment)" refers to the portion of
the value for Section 6.2 that is treated.
8.1 On- and Off-Site Disposal and Other
Releases
In Section 8.1, facilities report disposal and other
releases. This includes on-site disposal and other
releases reported in Section 5 and off-site disposal
and other releases reported in Section 6, but
excludes quantities reported in Section 5 and 6 due
to remedial actions, catastrophic events, or non-
production related one-time events (see the
discussion on Section 8.8). Note that EPCRA
Section 329(8) defines release as "any spilling,
leaking, pumping, pouring, emitting, emptying,
discharging, injecting, escaping, leaching, dumping,
or disposing into the environment (including the
abandonment of barrels, containers, and other closed
receptacles)."
Metals and metal category compounds reported in 1)
Section 6.2 as sent off-site for
stabilization/solidification (M41) or wastewater
treatment (excluding POTWs) (M62) and/or 2)
Section 6.1 - discharges to POTWs, should be
reported in Section 8.1. These quantities should
NOT be reported in Section 8.7 because the metals
are not ultimately destroyed.
Beginning in the 2003 reporting year, Section 8.1
was divided into four Subsections (8.1a, 8.1b, 8.1c
and 8.Id). Please refer to the following equations
that show the relationship between Sections 5, 6,
8.8, and 8. la through 8. Id.
Sections 8.1a and 8.1b. Toxic chemicals disposed
of or otherwise released on-site are reported in 8.1a
or 8.1b as appropriate. Toxic chemicals sent off-site
for disposal are reported in 8. lc or 8. Id.
Section 8.1a (Total on-site disposal to Class I
Underground Injection Wells, RCRA Subtitle C
landfills, and other landfills) = Section 5.4.1 +
Section 5.5.1A + Section 5.5.1B - Section 8.8 (on-
site disposal to landfills or UIC Class I Wells)2
Section 8.1b (Total other on-site disposal or other
releases) = Section 5.1 + Section 5.2 + Section 5.3
+ Section 5.4.2 + Section 5.5.2 + Section 5.5.3A +
Section 5.5.3B + Section 5.5.4 - Section 8.8 (on-
site disposal or other releases, other than disposal
to landfills or UIC Class I Wells)2
§ 8.8 includes quantities of toxic chemicals disposed of
or otherwise released on-site or managed as a waste off-
site due to remedial actions, catastrophic events, or one-
time events not associated with the production process. In
each equation, the parenthetical following "Section 8.8"
indicates which portion of § 8.8 is subtracted.

Part II Chemical Identification Information
Sections 8.1c and 8.1d. Toxic chemicals transferred
off-site to POTWs or other off-site locations and
then disposed of or otherwise released should be
reported in 8. lc or 8. Id as appropriate. For example,
quantities of a toxic chemical sent to a landfill, or
sent to a POTW and subsequently sent to a landfill
are reported in Section 8.1c, while quantities of a
toxic chemical sent to a surface impoundment, or
sent to a POTW and subsequently released to a
stream, are reported in Section 8.Id. Metals and
metal category compounds sent to POTWs should
be reported in one of these two sections and should
not be reported as treated for destruction in Section
8.7.
Section 8.1c (Total off-site disposal to Class I
Underground Injection Wells, RCRA Subtitle C
landfills, and other landfills) = Section 6.1
(portion of transfer that is not treated for
destruction and is ultimately disposed of in
landfills or UIC Class I Wells) + Section 6.2
(quantities associated with M codes M64, M65
and M81) - Section 8.8 (off-site disposal to
landfills or UIC Class I Wells)3
Section 8.1d (Total other off-site disposal or
other releases) = Section 6.1 (portion of transfer
that is not treated for destruction and is
ultimately disposed of or otherwise released,
other than disposal to landfills or UIC Class I
Wells) + Section 6.2 (quantities associated with M
codes M10, M41, M62, M66, M67, M73, M79,
M82, M90, M94, and M99) - Section 8.8 (off-site
disposal or other releases, other than disposal to
landfills or UIC Class I Wells)3
Some chemicals in addition to metals and metal
category compounds might not be treated for
destruction at a POTW. If you know that some or all
of a chemical is not treated for destruction at the
POTW, you should report that quantity in Section
8.1 (as indicated in the equations above) instead of
Section 8.7 (which is the quantity treated off-site).
In such cases, you may report using up to two
decimal places.
Removal and destruction rates for toxic chemicals
sent to POTWs, based on experimental and
estimated data, can be found in Table IV.
Sections 8.2 and 8.3: Energy Recovery
These relate to an EPCRA Section 313 chemical or
a mixture containing an EPCRA Section 313
chemical that is used for energy recovery on-site or
is sent off-site for energy recovery, unless it is a
commercially available fuel (e.g., fuel oil no. 6). For
the purposes of reporting on Form R, reportable on-
site and off-site energy recovery is the combustion
of a waste stream containing an EPCRA Section 313
chemical when:
(a)	The combustion unit is integrated into an
energy recovery system (i.e., industrial
furnaces, industrial kilns, and boilers); and
(b)	The EPCRA Section 313 chemical is
combustible and has a significant heating
value (e.g., 5000 BTU)
Note: Metals and metal category compounds cannot
be combusted for energy recovery. For metals and
metal category compounds, you should enter NA in
Sections 8.2 and 8.3.
Quantities used for energy recovery off-site that are
reported in Section 8.8 are excluded from Section
8.3.
Section 8.2 (Energy recovery on-site) = All
quantities used for on-site energy recovery
associated with methods reported in Section 7B
(on-site energy recovery processes)
Section 8.2 is not related to Sections 5 or 6.
Section 8.3 (Energy recovery off-site) = Section
6.2 (energy recovery) - Section 8.8 (off-site
energy recovery, not related to production)3
Sections 8.4 and 8.5: Recycling
These relate to an EPCRA Section 313 chemical in a
waste that is recycled on-site or is sent off-site for
recycling. Quantities recycled off-site that are
reported in Section 8.8 are excluded from Section
8.5.
3 § 8.8 includes quantities of toxic chemicals disposed of
or otherwise released on-site or managed as a waste off-
site due to remedial actions, catastrophic events, or one-
time events not associated with the production process. In
each equation, the parenthetical following "Section 8.8"

Section 8.4 is not related to Sections 5 or 6.
Section 8.5 (Recycling off-site) = Section 6.2
(recycling) - Section 8.8 (off-site recycling) 4
Sections 8.6 and 8.7: Treatment
These relate to an EPCRA Section 313 chemical
(except for most metals and metal category
compounds) or a waste containing an EPCRA
Section 313 chemical that is treated for destruction
on-site or is sent to a POTW or other off-site
location for treatment for destruction. Most metal
and category compounds are not reported in this
section because they cannot be destroyed (see
Appendix B). Quantities treated off-site that are
reported in Section 8.8 are excluded from Section
8.7.
Section 8.6 (Treatment on-site) = All quantities
used for on-site treatment associated with
methods reported in Section 7A (on-site waste
treatment methods and efficiency)
Section 8.6 is not related to Sections 5 or 6.
Section 8.7 (Treatment off-site) = Section 6.1
(portion of transfer that is ultimately treated) +
Section 6.2 (treatment) - Section 8.8 (off-site
treatment)4
Some chemicals in addition to metals and metal
category compounds might not be treated for
destruction at a POTW. If you know that some or all
of a chemical is not treated for destruction at the
POTW, you should report that quantity in Section
8.1 instead of Section 8.7. Facilities should use their
best readily available information to determine the
final disposition of the toxic chemical sent to the
POTW, and then distribute the amount reported in
Section 6.1 among Sections 8.1c, 8. Id, and 8.7, as
appropriate. Removal and destruction rates for toxic
chemicals sent to POTWs, based on experimental
and estimated data, can be found in Table IV.

8.8 Non-Production-Related Waste
In Section 8.8, enter the total quantity of the EPCRA
Section 313 chemical disposed of or released
directly into the environment or sent off-site for
recycling, energy recovery, treatment, or disposal
during the reporting year due to any of the following
events:
(1)	remedial actions;
(2)	catastrophic events such as earthquakes,
fires, or floods; or
(3)	other one-time events not associated with
normal or routine production processes.
These quantities should not be included in Sections
8.1,8.3, 8.5, or 8.7.
The purpose of this section is to separate quantities
recycled, used for energy recovery, treated, or
released (including disposals) that are associated
with normal or routine production operations from
those that are not. While all quantities released,
recycled, combusted for energy recovery, or treated
may ultimately be preventable, this section separates
the quantities that are more likely to be reduced or
eliminated by process oriented source reduction
activities from those releases that are largely
unpredictable and are less amenable to such source
reduction activities. For example, spills that occur as
a routine part of production operations and could be
reduced or eliminated by improved handling,
loading, or unloading procedures are included in the
quantities reported in Section 8.1 through 8.7 as
appropriate. A total loss of containment resulting
from a tank rupture caused by a tornado would be
included in the quantity reported in Section 8.8.
Similarly, the amount of an EPCRA Section 313
chemical cleaned up from spills resulting from
normal operations during the reporting year would
not be included in Section 8.8. However, the
quantity of the reported EPCRA Section 313
chemical disposed of from a remedial action (e.g.,
RCRA corrective action) to clean up the
environmental contamination resulting from past
practices should be reported in Section 8.8 because
they cannot currently be addressed by source
reduction methods. A remedial action for purposes
of Section 8.8 is a waste cleanup (including RCRA
and CERCLA operations) within the facility
boundary. Most remedial activities involve
collecting and treating contaminated material.
Also, releases caused by catastrophic events are to
be incorporated into the quantity reported in Section
8.8. Such releases may be caused by natural
disasters (e.g., hurricanes and earthquakes) or by
large scale accidents (e.g., fires and explosions). In
addition, releases due to other one-time events not
associated with production (e.g., terrorist bombing)
are to be included in Section 8.8. These amounts are
generally unanticipated and cannot be addressed by
routine process oriented accident prevention
techniques. By checking your documentation for
calculating estimates made for Part II, Section 5,
"Quantity of the Toxic Chemical Entering Each
Environmental Medium On-site," you may be able
to identify disposal and release amounts from the
above sources. Emergency notifications under
CERCLA and EPCRA as well as accident histories
required under the Clean Air Act may provide
useful information. You should also check facility
incident reports and maintenance records to identify
one time or catastrophic events.
Note: While the information reported in Section 8.8
represents only remedial, catastrophic, or other one-
time events not associated with production
processes, Section 5 of Form R (on-site disposal and
other releases to the environment) and Section 6
(off-site transfers for further waste management)
must include all on-site disposal and other releases
and transfers for disposal as appropriate, regardless
of whether they arise from catastrophic, remedial, or
routine process operations.
Avoid Double Counting in Sections 8.1 Through
8.8
Do not double or multiple count quantities in
Sections 8.1 through 8.8. The quantities reported in
each of those sections should be mutually exclusive.
In TRI-MEweb, any amounts that you designate as
non-production-related-waste (Section 8.8) will be
automatically excluded from production-related-
waste (Sections 8.1-8.7).

8.9 Production Ratio or Activity Ratio
For Section 8.9, you must provide either a
production or activity ratio and indicate which type
of ratio you reported using the checkboxes provided.
The production or activity ratio allows year-to-year
changes in release and other waste management
quantities to be viewed within the context of
production. For example, your production ratio lets
data users know whether your releases per unit of
output have gone up or down.
What Variable is Used to Calculate the
Production or Activity Ratio?
To calculate a production or activity ratio, you must
first select the variable(s) on which the ratio will be
based. In all cases, the production or activity_ratio
must be based on the variable(s) that best reflect the
output or outcome of the process(es) in which the
EPCRA Section 313 chemical is involved.
Examples of production or activity variables
selected by various industries can be found in
Example 25. Instructions for calculating a
production or activity ratio based on either a single
variable or multiple variables can be found below.
Production Ratio
A production ratio is a ratio of reporting year
production to prior year production. Calculate a
production ratio when the chemical is involved in
production processes. The equation for production
ratio is as follows:
[Production Variable] Current Year
Production Ratio =
[Production Variable] Pn0r Year
A production ratio may be based on production
levels for either the facility's end product or on the
intermediate product of the process in which the
chemical is manufactured, processed, or otherwise
used. If an EPCRA Section 313 chemical is used in
the production of refrigerators, for example, the
production ratio would be based on the number of
refrigerators produced. This is shown in Example 22
and in the sample equation below:
#	of refrigerators produced current Year
Example P.R. =	
#	of refrigerators produced pri0r Year
If the EPCRA Section 313 chemical is itself the
final product, the production ratio would be based
on the amount of the chemical manufactured.
Generally, however, the production ratio would be
based on a variable other than the quantity of the
EPCRA Section 313 chemical manufactured,
processed, or otherwise used.
Toxics Release Inventory Reporting Forms and Instructions
78
-------
Part II Chemical Identification Information
Activity Ratio
An activity ratio is also a ratio of current year to
prior year values, but is reported when a chemical is
involved in an activity not directly related to
production or production levels. An activity ratio is
appropriate if a chemical is used in an auxiliary
activity such as cleaning or pollution control, for
example, and is calculated as follows:
[Activity Variable] Current Year
Activity Ratio = 	
[Activity Variable] pri0r Year
In all cases, the variable used to calculate an activity
ratio should represent the intended outcome of the
activity in which the chemical is used or produced,
not the inputs of throughputs for the activity. If the
EPCRA Section 313 chemical is used to clean
molds, for example, the activity ratio could be based
on the number of cleanings or the number of molds
cleaned. It would not be based on the usage of the
EPCRA Section 313 chemical or the total volume of
cleaning solution used. This is shown in Example 23
and in the sample equation below:
#	of Molds Cleaned Current Year
Example A.R. =
#	of Molds Cleaned Pn0r Year
Production or Activity Ratios Based on Multiple
Variables
In some cases, your facility may use the same
EPCRA Section 313 chemical in more than one
process. If there is no single variable that adequately
reflects the output or outcome of the process(es) in
which the reported EPCRA Section 313 chemical is
involved, a production or activity ratio can be
calculated by weighting the different production or
activity variables for the different processes in
which the chemical is involved. The procedure for
this calculation is described in Example 26.
If the reported value is based on both production and
activity variables, you would report the final value
as a "production ratio" if the production ratio(s)
were weighted more heavily than the activity
ratio(s) in the calculations (and as an "activity ratio"
if the opposite were true).
Reporting Tips:
•	TRI-MEweb includes a production or
activity ratio wizard to help you calculate
your ratio automatically.
•	The ratio must be reported to the nearest
tenths or hundredths place (i.e., one or two
digits to the right of the decimal point) for
all EPCRA 313 chemicals, including PBT
chemicals. A zero is not an acceptable
response unless the calculated value is less
than 0.005, which can be rounded to zero.
•	If the manufacture, processing, or other use
of the reported EPCRA Section 313
chemical began during the current reporting
year, select NA as the production or activity
ratio. Otherwise, you must enter a value
even if your facility did not exceed a
reporting threshold for the chemical in the
previous reporting year.
•	The ratio is not to be reported as a percent
change between years (i.e., for a 10 percent
increase, you would report the ratio 1.10,
not 10% or 10). A production ratio of 1
indicates no change in production from the
prior year.
•	It is important to realize that if your facility
reports more than one reported EPCRA
Section 313 chemical, the production or
activity ratio may vary for different
chemicals if the chemicals are used in
different processes with different outputs.
•	Details regarding the method used to
calculate the Production or Activity Ratio
can be included in Section 9.1, "Additional
Information." This information will provide
context for the production or activity ratio

Example 26: Determining the Production Ratio Based on a Weighted Average
At many facilities, a reported EPCRA Section 313 chemical is used in more than one production process.
In these cases, a production ratio or activity ratio can be estimated bv weighting the production ratio for
each process based on the respective contribution of each process to the quantity of the reported EPCRA
Section 313 chemical managed as waste (recycled, used for energy recovery, treated, or disposed of).
Your facility paints bicycles with paint containing toluene. Sixteen thousand bicycles were produced in
the reporting year and 1.4.500 were produced in the prior year. There were no significant design
modifications that changed the total surface area to be painted for each bike. The production ratio for
bicycles is 1.1 (16.000/14.500). You estimate 12.500 pounds of toluene w as managed as waste (recycled,
used for energy recovery, treated, disposed of or released) as a result of bicy cle production processes.
Your facility also uses toluene as a solvent in a glue that is used to make components and add-on
equipment for the bicy cles. Thirteen thousand components were manufactured in the reporting y ear as
compared to 15.000 during the prior year. The production ratio for the components using toluene is 0.87
(13.000/15.000). You estimate 1.000 pounds of toluene w as managed as w asted as a result of components
production processes. The reported production ratio can be calculated by weighting the ratios for the
different variables based on the relative contribution each has to the total quantity of toluene managed as
waste during the reporting year (.13.500 pounds). The production ratio is calculated as follows:
Production ratio =1.1 x (12.500/13.500) + 0.87 x (1.000/13.500) = 1.08

8.10 Did Your Facility Engage in Any Newly
Implemented Source Reduction
Activities for This Chemical During the
Reporting Year?
Section 8.10 must be completed if a source
reduction activity involving the reported EPCRA
Section 313 chemical was newly implemented at
your facility. An activity is considered newly
implemented if it went into effect, in whole or in
part, during this reporting year. Some activities may
be multi-faceted or multi-phased and impact
different facility processes or span across multiple
years. For those activities, report on the discrete
projects that went into effect entirely or in part
during the reporting year. Accordingly, in
successive reporting years, you may report on later
facets or phases of the activity.
What Is Source Reduction?
Source reduction, as defined by the Pollution
Prevention Act, means any practice that:
•	Reduces the amount of any hazardous
substance, pollutant, or contaminant entering
any waste stream or otherwise released into the
environment (including fugitive emissions) prior
to recycling, energy recovery, treatment, or
disposal; and
•	Reduces the hazards to public health and the
environment associated with the release of such
substances, pollutants, or contaminants.
The term "source reduction" does not include any
practice that alters the physical, chemical, or
biological characteristics or the volume of a
hazardous substance, pollutant, or contaminant
through a process or activity that itself is not integral
to and necessary for the production of a product or
the providing of a service.
Source reduction activities include equipment or
technology modifications, process or procedure
modifications, reformulation or redesign of
products, substitution of raw materials, and
improvements in housekeeping, maintenance,
training, or inventory control. Newly implemented
source reduction activities include activities that
were implemented, in whole or in part, during the
reporting (e.g., improved loading procedures).
How Does Source Reduction Relate to the
Quantities Reported in Sections 8.1-8.8?
Source reduction activities reduce the amount of the
reported EPCRA Section 313 chemical disposed of
or otherwise released (as reported in Section 8.1),
used for energy recovery (as reported in Sections
8.2-8.3), recycled (as reported in Sections 8.4-8.5),
or treated (as reported in Sections 8.6-8.7).
Recycling, energy recovery, and treatment are not
themselves considered source reduction activities
because these practices occur after the chemical has
entered a waste stream.
The focus of the section includes only those
activities that are applied to reduce routine or
reasonably anticipated releases or other quantities of
the reported EPCRA Section 313 chemical managed
as waste). Thus, you do not report in this section any
activities taken to reduce or eliminate the quantities
reported in Section 8.8.
Why Is Reporting on Source Reduction Activities
Important?
The Pollution Prevention Act established the
national policy "that pollution should be prevented
or reduced at the source whenever feasible..."
Reporting on source reduction activities provides
important information for assessing progress
towards this goal.
To promote pollution prevention, EPA has increased
the prominence and accessibility of the pollution
prevention information reported in Sections 8.10
and 8.11 of the Form R. For example, companies
reporting source reduction are featured in the annual
TRI National Analysis report and the popular TRI
Pollution Prevention (P2) Search Tool. To learn
more, visit: https://www.epa.gov/tri/p2.
How Do I Report Source Reduction Activities
and Methods?
Instructions on how to report source reduction
activities (as defined above) and the methods used
to identify such activities are provided below.
• If Your Facility Implemented Source
Reduction Activities. If your facility
implemented a new source reduction activity for
the reported EPCRA Section 313 chemical
during the reporting year, report the activity or
activities that were implemented by selecting
the most relevant activity code(s) from the drop
down list in TRI-MEweb (see W-codes listed
below).
For each source reduction code you enter in
TRI-MEweb, a text box allows you to provide
additional details on that source reduction
practice. Similarly, to describe how each source
reduction practice was identified, a text box
Toxics Release Inventory Reporting Forms and Instructions
82
-------
Part II Chemical Identification Information
allows you to enter additional information on
the identification method(s) you selected.
Optional additional information about source
reduction provided via these text boxes is then
added to the next section of the Form R (Section
8.11, Optional Pollution Prevention
Information) preceded by the W- or T-code to
which it relates.
For each source reduction code you enter in
TRI-MEweb, a button to the right of the entry
opens a text box that allows you to provide
additional details on that source reduction
practice. Similarly, to describe how each source
reduction practice was identified, a button to the
right of the entry opens a text box that allows
you to enter additional information on the
identification method(s) you selected. Optional
additional information about source reduction
provided via these text boxes is then added to
the next section of the Form R (Section 8.11,
Optional Pollution Prevention Information)
preceded by the W- or T-code to which it
relates.
• If Your Facility Did Not Implement Source
Reduction Activities. If your facility did not
implement any new source reduction activity for
the reported EPCRA Section 313 chemical,
check the "NA" box in Section 8.10. TRI-
MEweb then provides you with the option of
selecting from one or more possible barriers that
your facility might be facing with regard to the
implementation of source reduction activities. A
list of barrier codes is provided below. For each
code, you also have the option to provide
additional information in a text box. (This
information is then added to your entry in
Section 8.11; see Section 8.11 instructions for
additional information on barriers to P2.)
How Do I Report Estimated Annual Reduction?
For each "Source Reduction Activity" reported, you
have the option to provide an estimate of the
resulting reduction in the annual amount of the
chemical managed as waste (i.e., released, recycled,
treated, or used for energy recovery). The estimated
annual reduction can be calculated as follows:
CB-A) x 100%
B
where:
A= estimated amount of the EPCRA Section 313
chemical to be managed as waste in the year
after the source reduction activity has been
implemented and
B = estimated amount of the EPCRA Section 313
chemical that would have been managed as
waste had the source reduction activity not
been implemented.
If you choose to complete this field, the reductions
associated with your pollution prevention efforts
will be featured on EPA's website through the TRI
Pollution Prevention Search Tool at
https://www.epa.gov/tri/p2. The estimated annual
reduction should be reported using the range codes
listed beneath the source reduction method codes.
Reporting Tips:
•	This estimate is based on the facility's best
readily available information at the time the
activity is reported and will not necessarily
reflect the actual reduction once implementation
of the activity is completed.
•	The estimated annual reduction only accounts
for the impact of the particular source reduction
activity. For example, if production is expected
to double, but chemical quantities are expected
to remain constant (when they also would have
doubled if not for the source reduction activity),
then the estimated annual reduction for the
activity is 50%.
Source Reduction Activity Codes
Source reduction activity codes are listed below. In
recent years many facilities have implemented green
chemistry and green engineering practices to
prevent pollution. In order to more closely represent
these practices, EPA has developed six new source
reduction codes. These codes are represented as:
W15; W43; W50; W56; W57; and W84 and are
provided in the list of source reductions below.
Scenarios as to when these codes should be used are
provided in Example 28.
Good Operating Practices
W13 Improved maintenance scheduling, record
keeping, or procedures
W14 Changed production schedule to minimize
equipment and feedstock changeovers
W15 Introduced in-line product quality

8.11 Optional Pollution Prevention
Information
In Section 8.11, you have the opportunity to provide
more detail about activities your facility undertook
to reduce releases of the EPCRA Section 313
chemical, including source reduction, recycling,
energy recovery, treatment or other pollution
controls. EPA encourages you to provide detail in
Section 8.11, as it offers your organization the
opportunity to showcase its achievements in
preventing pollution.
You can use the provided text boxes in TRI-MEweb
to describe your source reduction, recycling, or
pollution control activities.
While EPA welcomes submissions about recycling
and pollution control activities, the Agency is most
interested in collecting information about innovative
and effective source reduction activities, such as
green chemistry or green engineering practices. In
addition, the Agency wishes to encourage reporters
to provide enough detailed information about their
most effective source reduction activities to spur
other facilities to adopt similar practices, as well as
to inform the public about such activities being
implemented in their communities.
To encourage submissions with additional pollution
prevention information, EPA is increasing the
prominence and accessibility of this information.
Visit https://www.epa. gov/tri/p2 to learn how to
access this information (e.g., through the P2 Search
Tool tool) and to view examples of optional

source reduction activities/initiatives.
B2. Require technical information on pollution
prevention techniques applicable to specific
production processes.
B3. Concern that product quality may decline as
a result of source reduction.
B4. Source reduction activities were
implemented but were unsuccessful.
B5. Specific regulatory/permit burdens

B6. Pollution	prevention	previously
implemented- additional reduction does not
appear technically or economically feasible.
B7. No known substitutes or alternative
technologies.
B 8. Other barriers.
Each category you select in TRI-MEweb will be
included in your Section 8.11 entry, followed by the
additional details you provided on that topic (if any).
EPA believes this information is valuable in giving
a full picture of the source reduction activities your
facility engages in and what barriers you face in the
implementation of source reduction activities. EPA
also believes this information may allow for an
exchange between those that have knowledge of
source reduction practices, such as the EPA P2
Program, and those that are seeking additional help.
In addition, it will better enable EPA to identify
those technological areas for which EPA can
support basic research to identify alternative
technologies that are less polluting.

-------
Instructions for Completing Form R Schedule 1 (Dioxin and Dioxin-like Compounds)
E. Instructions for Completing
Form R Schedule 1 (Dioxin
and Dioxin-like Compounds)
E. 1 What is the Form R Schedule 1 ?
The Form R Schedule 1 is an adjunct to the Form R
that mirrors the data elements from Form R Part II
Chemical-Specific Information sections 5, 6, and 8
(current year only) and requires the reporting of the
individual grams data for each member of the dioxin
and dioxin-like compounds category present.
Facilities that file Form R reports for the dioxin and
dioxin-like compounds category are required to
determine if they have any of the information
required by the Form R Schedule 1. Facilities that
have any of the information required by Form R
Schedule 1 must submit individual member data via
the Form R Schedule 1 in addition to the Form R.
E.2 Who is required to file a Form R
Schedule 1?
Only facilities that file reports for the dioxin and
dioxin-like compounds category may be required to
file a Form R Schedule 1. Facilities that have any of
the data required by Form R Schedule 1 for the
individual members of the dioxin and dioxin-like
compounds category must submit a Form R
Schedule 1, in addition to the Form R. EPA notes
that dioxin and dioxin-like compounds are not
measured as a total quantity; the measurements are
based on the individual compounds within the
category. Emission factors for dioxin and dioxin-
like compounds are also based on emission factors
for the individual compounds within the category.
EPA's guidance document for dioxin and dioxin-
like compounds (Emergency Planning And
Community Right-To-Know Act - Section 313:
Guidance for Reporting Toxic Chemicals within the
Dioxin and Dioxin-like Compounds Category, EPA-
745-B-00-021, December 2000) includes tables that
contain the emission factors for the individual
members of the dioxin and dioxin-like compounds
category. Since measured data and emission factor
data are based upon data for the individual members
of the dioxin and dioxin-like compounds category,
the information required by Form R Schedule 1
should be available to facilities that file Form R
reports for the dioxin and dioxin-like compounds
category.
E.3 What information is reported on
the Form R Schedule 1 ?
The only data reported on the Form R Schedule 1 is
the mass quantity information required in sections 5,
6, and 8 (current year only) of the Form R. All of
the other information required in sections 5, 6, and 8
of the Form R (off-site location names, stream or
water body names, etc.) would be the same so this
information is not duplicated on Form R Schedule 1.
For example, if a facility reported 5.3306 grams on
Form R Section 5.1 for fugitive or non-point air
emissions for the dioxin and dioxin-like compounds
category then the facility would report on the Form
R Schedule 1 the grams data for each individual
member of the category that contributed to the
5.3306 gram total. The sum of the gram quantities
reported for each individual member of the category
should equal the total gram quantity reported for the
category on Form R for each data element (see
examples in Figure 8). The NA box has the same
meaning on Form R Schedule 1 as it does on the
Form R and should only be marked if it is marked
on the Form R.
It is extremely important that facilities enter their
grams data for the individual members of the
category based on the order shown in the Individual
Members of the Dioxin and Dioxin-like
Compounds Category table on page 91. This
information will be used to calculate toxic
equivalency values using toxic equivalency factors
that are specific to each member of the category. As
with reporting on the Form R, facilities should
report on the Form R Schedule 1 to the level of
accuracy that their data supports, up to seven digits
to the right of the decimal. EPA's reporting software
and data management systems support data
precision to seven digits to the right of the decimal.

The Form R Schedule 1 provides boxes for recording the gram quantities for all 17 individual members of
the dioxin and dioxin-like compounds category. The boxes on the Form R Schedule 1 for each release type
are divided into 17 boxes. Each of the boxes (1-17) corresponds to the individual members of the dioxin
category as presented in Table I.

E.4 How do I report Form R
Schedule 1 Data?
The Electronic Reporting of Toxics Release
Inventory Data rule requires that all Dioxin and
Dioxin-like Compound data must be submitted
electronically via TRI-MEweb. For each data
element in Sections 5, 6, and 8 (current year only),
TRI-MEweb has a clickable button labeled
"Schedule 1" that loads a separate page
Release/Transfer Quantities by Category Member.
In this page, you can enter the individual quantities
for each category member. TRI-MEweb will
automatically calculate the category total. If any
releases or transfer were due to non-production-
related wastes (see Chapter 2, Part II, Section 8.8),
enter those values on the same page. If your facility
does not have individual member data, you can
select the checkbox labeled "I would like to enter
total grams of Dioxin and Dioxin-like Compounds"
and the "Next" button to enter total quantities.

Optional Facility-Level Information and Non-Reporting
F. Optional Facility-Level
Information and Non-
Reporting
Although there is no requirement to inform the
EPA of updates to a facility's contact and location
information outside of what is required on a TRI
reporting form, each year some facilities
voluntarily elect to provide this information to the
EPA. Additionally, each reporting year some
facilities contact EPA to indicate that they will no
longer be reporting to TRI or will not be submitting
a form for one or more specific TRI-listed
chemicals.
Facilities can use TRI-MEweb to provide optional
facility-level information for the following
categories:
•	Facility name has changed
•	Facility technical contact has changed
•	Facility public contact has changed
•	Facility has relocated to a new physical
address
•	Facility merged with another location
•	Facility has closed
•	Facility was temporarily shut down
•	Facility did not have 10 or more full-time
employee equivalents
•	Facility is not in a covered NAICS sector
•	Facility fell below reporting threshold for
one or more chemicals due to source
reduction
•	Facility fell below reporting threshold for
one or more chemicals due to exemption
Facility fell below reporting threshold for
one or more chemicals due to reason(s)
other than source reduction or use of an
exemption

the de minimis exemption is not available for these chemicals (an asterisk appears where a de minimis limit would otherwise appear
in Table II). However, for purposes of the supplier notification requirement only, such limits are provided in Appendix C.
Chemical Qualifiers
Certain EPCRA Section 313 chemicals listed in Table II have parenthetic "qualifiers." These qualifiers indicate that these EPCRA
Section 313 chemicals are subject to the section 313 reporting requirements if manufactured, processed, or otherwise used in a
specific form or when a certain activity is performed. An EPCRA Section 313 chemical that is listed without a qualifier is subject to
reporting in all forms in which it is manufactured, processed, and otherwise used. The following chemicals are reportable only if
they are manufactured, processed, or otherwise used in the specific form(s) listed below:

Table II EPCRA Section 313 Chemical List for Reporting Year 2016
Supplier Notification Implications
There are no supplier notification requirements for isopropyl
alcohol and saccharin since the processors and users of these
chemicals are not required to report. Manufacturers of these
chemicals do not need to notify their customers that these are
reportable EPCRA section 313 chemicals.
Qualifier Definitions
Fume or dust. Two of the metals on the list (aluminum and
zinc) contain the qualifier "fume or dust." Fume or dust refers to
dry forms of these metals but does not refer to "wet" forms such
as solutions or slurries. As explained in Section B.3.a of these
instructions, the term manufacture includes the generation of an
EPCRA Section 313 chemical as a byproduct or impurity. In
such cases, a facility should determine if, for example, it
generated more than 25,000 pounds of aluminum fume or dust in
the reporting year as a result of its activities. If so, the facility
must report that it manufactures "aluminum (fume or dust)."
Similarly, there may be certain technologies in which one of
these metals is processed in the form of a fume or dust to make
other EPCRA Section 313 chemicals or other products for
distribution in commerce. In reporting releases, the facility
would only report releases of the fume or dust.
EPA considers dusts to consist of solid particles generated by any
mechanical processing of materials including crushing, grinding,
rapid impact, handling, detonation, and decrepitation of organic
and inorganic materials such as rock, ore, and metal. Dusts do
not tend to flocculate, except under electrostatic forces.
EPA considers a fume to be an airborne dispersion consisting of
small solid particles created by condensation from a gaseous
state, in distinction to a gas or vapor. Fumes arise from the
heating of solids such as lead. The condensation is often
accompanied by a chemical reaction, such as oxidation. Fumes
flocculate and sometimes coalesce.
Manufacturing qualifiers. Two of the entries in the EPCRA
Section 313 chemical list contain a qualifier relating to
manufacture. For isopropyl alcohol, the qualifier is "only persons
who manufacture by the strong acid process are subject, no
supplier notification." For saccharin, the qualifier is "only
persons who manufacture are subject, no supplier notification."
For isopropyl alcohol, the qualifier means that only facilities
manufacturing isopropyl alcohol by the strong acid process are
required to report. In the case of saccharin, only manufacturers
of the EPCRA Section 313 chemical are subject to the reporting
requirements. A facility that only processes or otherwise uses
either of these EPCRA Section 313 chemicals is not required to
report for these EPCRA Section 313 chemicals. In both cases,
supplier notification does not apply because only manufacturers,
not users, of these two EPCRA Section 313 chemicals must
report.
Ammonia (includes anhydrous ammonia and aqueous
ammonia from water dissociable ammonium salts and other
sources; 10 percent of total aqueous ammonia is reportable
under this listing). The qualifier for ammonia means that
anhydrous forms of ammonia are 100% reportable and aqueous
forms are limited to 10% of total aqueous ammonia. Therefore
when determining threshold and releases and other waste
management quantities all anhydrous ammonia is included but
only 10% of total aqueous ammonia is included. Any
evaporation of ammonia from aqueous ammonia solutions is
considered anhydrous ammonia and should be included in
threshold determinations and release and other waste
management calculations.
Sulfuric acid and Hydrochloric acid (acid aerosols including
mists, vapors, gas, fog, and other airborne forms of any
particle size). The qualifier for sulfuric acid and hydrochloric
acid means that the only forms of these chemicals that are
reportable are airborne forms. Aqueous solutions are not covered
by this listing but any aerosols generated from aqueous solutions
are covered.
Nitrate compounds (water dissociable; reportable only when
in aqueous solution). The qualifier for the nitrate compounds
category limits the reporting to nitrate compounds that dissociate
in water, generating nitrate ion. For the purposes of threshold
determinations the entire weight of the nitrate compound must be
included in all calculations. For the purposes of reporting
releases and other waste management quantities only the weight
of the nitrate ion should be included in the calculations of these
quantities.
Phosphorus (yellow or white). The listing for phosphorus is
qualified by the term "yellow or white." This means that only
manufacturing, processing, or otherwise use of phosphorus in the
yellow or white chemical form triggers reporting. Conversely,
manufacturing, processing, or otherwise use of "black" or "red"
phosphorus does not trigger reporting. Supplier notification also
applies only to distribution of yellow or white phosphorus.
Asbestos (friable). The listing for asbestos is qualified by the
term "friable," referring to the physical characteristic of being
able to be crumbled, pulverized, or reducible to a powder with
hand pressure. Only manufacturing, processing, or otherwise use
of asbestos in the friable form triggers reporting. Supplier
notification applies only to distribution of mixtures or other trade
name products containing friable asbestos.
Aluminum Oxide (fibrous forms). The listing for aluminum
oxide is qualified by the term "fibrous forms." Fibrous refers to a
man-made form of aluminum oxide that is processed to produce
strands or filaments which can be cut to various lengths
depending on the application. Only manufacturing, processing,
or otherwise use of aluminum oxide in the fibrous form triggers
reporting. Supplier notification applies only to distribution of
mixtures or other trade name products containing fibrous forms
of aluminum oxide.

Table IV. Removal and Destruction Rates for POTWs
When completing Section 8 of the Form R, facilities should use their best readily available information to determine the final
disposition of toxic chemical sent to the publicly owned treatment works (POTW) and then distribute the amount reported in Section
6.1 among Sections 8. lc, 8. Id, and 8.7, as appropriate. Table VI presents data from EPA's Risk-Screening Environmental Indicators
(RSEI) model that can be used to assist with these calculations.
To predict the fate and transport of TRI chemicals, the RSEI model uses estimates of chemical removal efficiencies at POTWs and
of the ultimate fate of the chemical amount removed. The amount of the chemical removed is divided into the percentages removed
by (1) sorbing to sludge, (2) volatilizing into the air or (3) being biodegraded by microorganisms. Table VI assigns the portion of the
influent diverted to sludge to Section 8.1c (off-site disposal to landfills and Class IUIC wells), the portion volatilizing into the air to
Section 8. Id (other off-site releases), and the portion being biodegraded to Section 8.7 (off-site treatment). The percentage of the
influent chemical that passes through the POTW and is not removed is also assigned to Section 8. Id.
POTW removal efficiencies are a function of many factors, including the treatment technology in place at the POTW. Information
about the final disposition of chemicals at the specific POTW in question should therefore be used in place of the percentages in
Table VI if available. Additional documentation for the values presented in Table VI can be found in Technical Appendix B of the
RSEI Model Documentation, available at: http://www2.epa.gov/toxics-release-inventorv-tri-program/documentation-potw-removal-
rates.
TRI-MEweb will use the percentages below to calculate values for Sections 8. lc, 8. Id, and 8.7 unless you replace these default
percentages with location-specific estimates of removal and destruction rates for the POTW in question. For chemicals not included
in this table, TRI-MEweb's default assumption is that 100% of the chemical sent to the POTW is treated for destruction.

Appendix A. TRI Federal Facility Reporting
Information
Special Instructions for TRI Federal
Facility Reporting
A.1 Why Do Federal
Facilities Need to Report?
Executive Order 13693, "Planning for Federal
Sustainability in the Next Decade," requires federal
agencies to comply with the Emergency Planning and
Community Right-To-Know Act of 1986 (EPCRA) and
the Pollution Prevention Act of 1990 (PPA). Federal
facilities have been subject to EPCRA section 313 and
PPA since reporting year 1994. TRI submissions are due
to EPA on July 1 of the year following each reporting
(calendar) year. Reporting by the federal facility does not
alter the reporting obligation of on-site contractors.
Contracts entered into after the date of this order for
contractor operation of government-owned facilities or
vehicles require the contractor to comply with the
provisions of this order with respect to such facilities or
vehicles to the same extent as the agency would be
required to comply if the agency operated facilities or
vehicles.
For more information on Executive Order 13693, please
refer to the implementing instructions which can be found
on the TRI web page: https://www.epa.gov/toxics-
release-inventorv-tri-program/tri-laws-rulemakings-and-
notices
A.2 Identifying Federal
Facility Reports
Federal facility reports are identified as federal by several
indicators on the form. The facility name and parent
company name are critical indicators and must be
reported as described below. Another critical indicator is
the federal facility report box, Part I, 4.2c. Federal
facilities only should check this box to indicate that the
report is from a federal agency for a federal facility;
federal facilities should not check the GOCO box, (Part I,
Section 4.2d of the Form R). Contractors located at
federal facilities (GOCOs) should check the GOCO box
(Part I, Section 4.2d of the Form R); they should not
check the box 4.2c. Facilities should also complete the
partial or complete facility blocks (Form R page 2, block
4.2a and 4.2b) as appropriate. If you are a federal facility
reporting for the first time, you should write "new" in the
TRI Facility ID (TRIFID) box, even if a contractor has
reported for your facility in the past. The contractor will
retain the original TRIFID. You will be assigned a new
TRIFID the first time you report.
A.3 The "Double
Counting" Problem
As structured, the law and the executive order require
both regulated industries and the federal government to
report TRI data, sometimes for the same site. In order to
prevent duplicate data in the TRI database, which could
result in "double counting" data for some chemicals and
locations, EPA must be able to identify and distinguish
the GOCO reports submitted by the federal contractor
from the federal facility reports which contain data for
the same site. To accomplish this, federal facility reports
should be accompanied by either 1) exact electronic
copies of all contractor TRI reports, including when the
totals reported by the federal facility are greater than
those reported by the contractor(s), or 2) a cover letter
with a list of the facility contractors that submit TRI
reports to EPA, identifying each contractor by name, TRI
technical contact, and TRI facility name and address.
Additionally, federal facilities should check Form R, Part
I, Section 4.2c, while contractors at federal facilities
should check Form R, Part I, Section 4.2d.
A.4 How to Report Your
Facility Name
Facility name is a critical data element. It is used by EPA
to create the TRI facility ID number (TRIFID), which is a
unique number designed to identify a facility site. The
facility name and TRIFID number are used by all TRI
data users to link data from a single site across multiple
reporting years. A federal facility is assigned a new
TRIFID number when the federal report is entered into
the Toxics Release Inventory system for the first time.
This TRIFID number, generated when the first report is
entered into the Toxics Release Inventory System, will be
included in future reporting packages sent to the federal
facility, and should be used by the federal facility in all
future reports.
Federal facilities should report their facility name in
Section 4.1 as shown in the following example:
U.S. DOE Savannah River Site
It is very important that the agency name appear first,
followed by the specific plant or site name.
Federal contractors at GOCO facilities should report their
names as shown in the following example:
U.S. DOE Savannah River Site - Westinghouse
Operations.
Toxics Release Inventory Reporting Forms and Instructions
A-l
-------
Appendix A
A.5 How to Report Your
North American Industry
Classification System
(NAICS) Code
Federal facilities should report the NAICS code which
most closely represents the activities taking place at the
site. Section A. 10 lists the Public Administration NAICS
codes covering executive, legislative, judicial,
administrative and regulatory activities of the Federal
government. Government-owned and operated business
establishments are classified in major NAICS groups
according to the activity in which they are engaged. For
example, a Veterans Hospital would be classified in
Group 806 - Hospitals.
A.6 How to Report Your
"Parent Company" Name
Federal facilities should report their parent company
name on page 2 of the Form Rs (Section 5.1) by reporting
their complete Department or Agency name, as shown in
the following example:
U.S. Department of Energy
Block 5.2, Parent Company's Dun & Bradstreet Number,
should be marked NA.
Federal contractors at GOCO facilities should not report a
federal department or agency name as their parent
company. A federal name in the parent company name
field will classify the report as federal, and the GOCO
may be identified as a non-reporter.
A.7 How to Revise Your
Data After It Has Been
Submitted
Effective January 21, 2013, facilities may only revise TRI
reporting forms submitted for Reporting Year 1991
through the current reporting year. Use TRI-MEweb to
submit revisions to non-trade secret TRI submissions.
If you have questions about using TRI-MEweb to revise
your Form R/A, please refer to the TRI-MEweb tutorial
page at: https://www.epa.gov/toxics-release-inventorv-
tri-program/training.
Facilities may request a revision for one or more of the
following reasons:
Revision codes:
•	RR1 - New Monitoring Data
•	RR2 - New Emission Factor(s)
•	RR3 - New Chemical Concentration Data
•	RR4 - Recalculation(s)
•	RR5 - Other Reason(s)
Please note that late submissions for chemicals not
reported in a previous reporting year are not considered
revisions for that year.
Facilities are reminded that there is a legal obligation to
file an accurate and complete Form R or Form A report
for each chemical by July 1 each year. EPA may take
enforcement action and assess civil administrative
penalties regarding corrections to errors in Form R
reports that are not changes based on previously
unavailable information or procedures which improve the
accuracy of the data initially reported. The kinds of errors
which may result in enforcement and in penalties include
but are not limited to the following: (1) Errors caused by
not using the most readily available information, for
example, not using monitoring data collected for
compliance with other regulations in calculating releases;
(2) omitting a major source of emissions; (3) a
mathematical or transcription or typographical error
which seriously compromises the accuracy of the
information, and; (4) other errors which seriously affect
the utility of the data, particularly errors in release
reporting for which the facility has no records showing
the derivation of the release calculation, and cannot
provide a sufficient explanation of the report.
How do I revise my submission(s)?
If you plan to revise a TRI submission, you must send
revised report(s) to EPA and the appropriate state or
tribal agency.
You must use TRI-MEweb to submit revisions to non-
trade secret TRI submissions. EPA will only accept
revisions for Reporting Year 1991 through the current
year.
A.8 Who Should Sign
Federal Form R Reports?
Federal Form R reports should be certified by the senior
federal employee on-site. If no federal employee is on-
site, federal Form R reports must be certified by the
senior federal employee with management responsibility
for the site. Federal Form R reports should be certified by
a federal employee. Contractor employee certifications
are not considered valid on federal reports.

B.2 Reporting the Waste Management of Metals
This appendix outlines how the TRI-MEweb reporting software restricts reporting for metals when the specific data
element or waste management code is not applicable for a particular chemical. Below is a list of metals divided into
four groups along with charts that help explain where quantities of these chemicals can and cannot be reported on the
Form R using TRI-MEweb. In addition, there are charts that explain restrictions on reporting waste management codes
for the toxic chemicals in each of the four groups. This appendix only shows where reporting is restricted in TRI-
MEweb, it does not indicate every situation where a metal should not be reported in a specific section of the form. For
example, TRI-MEweb does not restrict the reporting of most individually-listed metal compounds as used for energy
recovery (Sections 8.2 and 8.3) even though some of these chemicals do not have a heat value greater than 5000 British
thermal units (Btu) and, thus, cannot be combusted for energy recovery. It is left to the facility to decide which of these
toxic chemicals can be used for energy recovery. If you are not using TRI-MEweb this appendix can serve as a guide to
help you understand where it is not appropriate to report certain quantities of toxic chemicals or waste management
codes on your Form R.

Section 7A. On-site Waste Treatment Methods and Efficiency
TRI-MEweb allows any toxic chemical to be reported in Section 7 A, however, it limits reporting in two ways. First,
TRI-MEweb limits the treatment codes that can be reported based on the General Waste Stream Code selected. If a
TRI-MEweb user selects General Waste Stream code "A - Gaseous", all Waste Treatment Codes are made available.
However, if a user selects from the remaining three General Waste Stream Codes (W - Wastewater, L - Liquid waste
streams, or S - Solid waste streams), the "Air Emissions Treatment" Waste Treatment Codes are not made available.
Second, the software restricts reporting for certain toxic chemicals with qualifiers. When reporting zinc (fume or dust)
or aluminum (fume or dust) TRI-MEweb will not allow the user to select General Waste Stream Codes W-Wastewater
and L-Liquid waste streams because the fume or dust form of a toxic chemical cannot exist in a liquid or water waste.
For asbestos (friable) only S - Solid or A - Gaseous can be selected. When reporting hydrochloric acid (acid aerosols)
or sulfuric acid (acid aerosols) only A - Gaseous can be selected.

1	Although TRI-MEweb does not restrict reporting of most individually-listed metal compounds as transferred off site for
energy recovery, only chemicals with a heat value greater than 5000 British thermal units that are combusted in a device
that is an industrial furnace or boiler (40 CFR Section 372.3) should be reported as used for energy recovery.
2	The toxic chemical category barium compounds (N040) does not include barium sulfate. Because barium sulfate is not a
listed toxic chemical, the conversion in a waste stream of barium or barium compound to barium sulfate is considered
treatment for destruction (40 CFR Section 372.3).

Appendix C. Supplier Notification Requirements
EPA requires some suppliers of mixtures or other trade
name products containing one or more of the EPCRA
section 313 chemicals to notify their customers. This
requirement has been in effect since January 1, 1989.
This appendix explains which suppliers must notify their
customers, who must be notified, what form the notice
must take, and when it must be sent.
C.1 Who Must Supply
Notification
You are covered by the section 313 supplier notification
requirements if you own or operate a facility which meets
all of the following criteria:
1.	Your facility is in a North American Industry
Classification System (NAICS) code that
corresponds to Standard Industrial Classification
[SIC] codes 20-39;
2.	You manufacture (including import) or process
an EPCRA section 313 chemical; and
3.	You sell or otherwise distribute a mixture or
other trade name product containing the EPCRA
section 313 chemical to either:
-	A facility in a covered NAICS code (see
Table I).
-	A person that then may sell the same
mixture or other trade name product to a
firm in a covered NAICS code (see Table
I).
Note that you may be covered by the supplier
notification rules even if you are not covered by the
section 313 release reporting requirements. For
example, even if you have fewer than 10 full-time
employees or do not manufacture or process any of the
EPCRA section 313 chemicals in sufficient quantities to
trigger the release and other waste management reporting
requirements, you may still be required to notify certain
customers.
C.2 Who Must Be Notified
Industries whose primary NAICS code does not
correspond to SIC codes 20 through 39 are not required
to initiate the distribution of notifications for EPCRA
section 313 chemicals in mixtures or other trade name
products that they send to their customers.
However, if these facilities receive notifications from
their suppliers about EPCRA section 313 chemicals in
mixtures or other trade name products, they should
forward the notifications with the EPCRA section 313
chemicals they send to other covered users.
An example would be if you sold a lacquer containing
toluene to distributors who then may sell the product to
other manufacturers. The distributors are not in a
covered NAICS code, but because they sell the product to
companies in covered NAICS codes, they must be
notified so that they may pass the notice along to their
customers, as required.
The language of the supplier notification requirements
covers mixtures or other trade name products that are
sold or otherwise distributed. The "otherwise distributes"
language includes intra-company transfers and, therefore,
the supplier notification requirements at 40 CFR Section
372.45 apply.
C.3 Supplier Notification
Content
The supplier notification must include the following
information:
1.	A statement that the mixture or other trade name
product contains an EPCRA section 313
chemical or chemicals subject to the reporting
requirements of EPCRA section 313 (40 CFR
372);
2.	The name of each EPCRA section 313 chemical
and the associated Chemical Abstracts Service
(CAS) registry number of each chemical if
applicable. (CAS numbers are not used for
chemical categories, since they can represent
several individual EPCRA section 313
chemicals.); and
3.	The percentage, by weight, of each EPCRA
section 313 chemical (or all EPCRA section 313
chemicals within a listed category) contained in
the mixture or other trade name product.
For example, if a mixture contains a chemical (i.e., 12
percent zinc oxide) that is a member of a reportable
EPCRA section 313 chemical category (i.e., zinc
compounds), the notification must indicate that the
mixture contains a zinc compound at 12 percent by
weight. Supplying only the weight percent of the parent
metal (zinc) does not fulfill the requirement. The
customer must be told the weight percent of the entire
compound within an EPCRA section 313 chemical
category present in the mixture.
Toxics Release Inventory Reporting Forms and Instructions
C-l
-------
Appendix C
OA How the Notification
Must Be Made
The required notification must be provided at least
annually in writing. Acceptable forms of notice include
letters, product labeling, and product literature distributed
to customers. If you are required to prepare and
distribute a Safety Data Sheet (SDS) for the mixture
under the Occupational Safety and Health Act (OSHA)
Hazard Communication Standard, your section 313
notification must be attached to the SDS or the SDS must
be modified to include the required information. (A
sample letter and recommended text for inclusion in an
SDS appear at the end of this appendix.)
You must make it clear to your customers that any copies
or redistribution of the SDS or other form of notification
must include the section 313 notice. In other words, your
customers should understand their requirement to include
the section 313 notification if they give your SDS to their
customers.
C.5 When Notification
Must Be Provided
You must notify each customer receiving a mixture or
other trade name product containing an EPCRA section
313 chemical with the first shipment of each calendar
year. You may send the notice with subsequent
shipments as well, but it is required that you send it with
the first shipment each year. Once customers have been
provided with an SDS containing the section 313
information, you may refer to the SDS by a written letter
in subsequent years (as long as the SDS is current).
If EPA adds EPCRA section 313 chemicals to the section
313 list, and your products contain the newly added
EPCRA section 313 chemicals, notify your customers
with the first shipment made during the next calendar
year following EPA's final decision to add the chemical
to the list. For example, if EPA adds chemical ABC to
the list in September 1998, supplier notification for
chemical ABC would have begun with the first shipment
in 1999.
You must send a new or revised notice to your customers
if you:
1.	Change a mixture or other trade name product
by adding, removing, or changing the percentage
by weight of an EPCRA section 313 chemical;
or
2.	Discover that your previous notification did not
properly identify the EPCRA section 313
chemicals in the mixture or correctly indicate
the percentage by weight.
In these cases, you must:
1.	Supply a new or revised notification within 30
days of a change in the product or the discovery
of misidentified EPCRA section 313 chemical(s)
in the mixture or incorrect percentages by
weight; and
2.	Identify in the notification the prior shipments of
the mixture or product in that calendar year to
which the new notification applies (e.g., if the
revised notification is made on August 12,
indicate which shipments were affected during
the period January 1-August 12).
C.6 When Notifications
Are Not Required
Supplier notification is not required for a "pure" EPCRA
section 313 chemical unless a trade name is used. The
identity of the EPCRA section 313 chemical will be
known based on label information.
You are not required to make a "negative declaration."
That is, you are not required to indicate that a product
contains no EPCRA section 313 chemicals.
If your mixture or other trade name product contains one
of the EPCRA section 313 chemicals, you are not
required to notify your customers if:
1. Your mixture or other trade name product
contains the EPCRA section 313 chemical in
percentages by weight of less than the following
levels (These are known as de minimis levels)
-	0.1 percent if the EPCRA section 313
chemical is defined as an "OSHA
carcinogen;"
-	1 percent for other EPCRA section 313
chemicals.
De minimis levels for each EPCRA section 313 chemical
and chemical category are listed in Table II. PBT
chemicals (except lead when contained in stainless steel,
brass or bronze alloys) are not eligible for the de minimis
exemption. Therefore, de minimis levels are not provided
for these chemicals in Table II. However, for purposes of
supplier notification requirements only, such notification
is not required when the following PBT chemicals are
contained in mixtures below their respective de minimis
levels:

packaged for distribution to the general
public.

management. The supplier notification
requirements apply only to mixtures and trade
name products. They do not apply to wastes.

5169, or 5171, or 7389 (limited to facilities
primarily engaged in solvents recovery services
on a contract or fee basis).
C.7 Trade Secrets
Chemical suppliers may consider the chemical name or
the specific concentration of an EPCRA section 313
chemical in a mixture or other trade name product to be a
trade secret. If they consider:
1.	The specific identity of an EPCRA section 313
chemical to be a trade secret, the notice must
contain a generic chemical name that is
descriptive of the structure of that EPCRA
Section 313 chemical (for example,
decabromodiphenyl oxide could be described as
a halogenated aromatic);
2.	The specific percentage by weight of an EPCRA
section 313 chemical in the mixture or other
trade name product to be a trade secret, the
notice must contain a statement that the EPCRA
section 313 chemical is present at a
concentration that does not exceed a specified
upper bound. For example, if a mixture contains
12 percent toluene and you consider the
percentage a trade secret, the notification may
state that the mixture contains toluene at no
more than 15 percent by weight. The upper
bound value chosen must be no larger than
necessary to adequately protect the trade secret.
If you claim this information to be trade secret, you must
have documentation that provides the basis for your
claim.
C.8 Recordkeeping
Requirements
You are required to keep records of the following for
three years:
1.	Notifications sent to recipients of your mixture
or other trade name product;
2.	All supporting materials used to develop the
notice;
3.	If claiming a specific EPCRA section 313
chemical identity a trade secret, you should
record why the EPCRA section 313 chemical
identity is considered a trade secret and the
appropriateness of the generic chemical name
provided in the notification; and
4.	If claiming a specific concentration a trade
secret, you should record explanations of why a
specific concentration is considered a trade
secret and the basis for the upper bound
concentration limit.
Information retained under 40 CFR 372 must be readily
available for inspection by EPA.

Appendix F. Questions and Answers Regarding
Facility Identification Information	
F.1 Categories
This document provides additional information about TRI
reporting procedures based on some frequently asked
questions. The questions and their answers are organized
into three groups:
Section 1.2 Identifying the parent company.
Section 1.3 Reporting after a change in name or
ownership.
Section 1.4 Reporting for multiple sites and/or owners.
F.2 Identifying the Parent
Company
A. Question
When a facility changes ownership after a Form R has
been submitted, who is required to respond to a Notice of
Noncompliance (NON) related to the Form R? Is the
current or prior owner/operator required to respond to the
NON?
A. Answer
The current owner/operator has the primary responsibility
for responding to a NON. However, all prior
owners/operators back to January 1 of the reporting year
may also be held responsible if the current
owner/operator does not respond to the NON in an
accurate, complete, and timely manner.
(Source: 1998 EPCRA Section 313 Questions and
Answers Document, Question #52 (EPA 745-B-98-004)).
B. Question
Who is the parent company for a 50/50 joint venture?
B. Answer
The 50/50 joint venture is its own parent company.
(Source: 1998 EPCRA Section 313 Questions and
Answers Document, Question #54 (EPA 745-B-98-004)).
F.3 Reporting After a
Change in Name or
Ownership
A. Question
The owner/operator of a covered facility is preparing
Form Rs for a facility. The facility and its parent
company both changed their names after the reporting
year. What names should be reported by the
owner/operator (for both the facility and the parent
company) on the Form Rs covering the reporting year?
A. Answer
The facility should report the names used by the facility
and parent company during that reporting year. When the
owner/operator submits Form Rs for the next reporting
year, these reports should reflect the names used by the
facility and parent company during the new reporting
year. Note that the TRI facility identification number
will not change.
(Source: 1998 EPCRA Section 313 Questions and
Answers Document, Question #614 (EPA 745-B-98-
004)).
B. Question
If a covered facility does not have a Dun & Bradstreet
(D&B) number but the parent corporation does, should
this number be reported?
B. Answer
Report the D&B number for the facility. If a facility does
not have a D&B number, enter "NA" in Part I, Section
4.7. The corporate D&B number should be entered in
Part I, Section 5.2 relating to parent company
information.
(Source: 1998 EPCRA Section 313 Questions and
Answers Document, Question #621 (EPA 745-B-98-
004)).
C. Question
Mom and Pop Plastics is a wholly owned subsidiary of a
major chemical company which is a wholly owned
subsidiary of Big Oil Corporation, located in St. Paul,
Minnesota. Which is the parent company?
C. Answer
Big Oil Corporation is the parent company.

Appendix F
C. Question
In October 2015, Facility X changes ownership and is
purchased by Company Y. For the 2015 reporting year,
which facility is obligated to submit the Form R or Form
A, and whose name and what TRI identification number
should be on the form?
C. Answer
The owner or operator of the facility on the annual July 1
reporting deadline (i.e., Company Y) is primarily
responsible for reporting the data for the entire previous
year's operations at that facility. Any other owner or
operator of the facility before the reporting deadline may
also be held liable. The form submitted for a given
reporting year must reflect the names used by the facility
and its parent company on December 31 of that reporting
year, even if the facility changed its name or ownership at
any time during the reporting year. In this scenario,
because Facility X changed ownership before December
31 of the reporting year, Company Y's name should
appear on the form. The TRI identification number is
location-specific; thus, the identification number will stay
the same even if the facility changes names, production
processes, or NAICS codes.
(Source: Monthly Call Center Report Question EPA530-
R-98—5j; October 1998).
F.4 Reporting for Multiple
Sites and/or Owners
A. Question
If two plants are separate establishments under the same
site management, must they have separate D&B
numbers?
A. Answer
They may have separate D&B numbers, especially if they
are distinctly separate business units. However, different
divisions of a company located at the same facility
usually do not have separate D&B numbers.
(Source: 1998 EPCRA Section 313 Questions and
Answers Document, Question #622 (EPA 745-B-98-
004)).
B. Question
An electricity generating facility (EGF) is comprised of
multiple independent owners. Each individual owner runs
his/her own separate operation, but each has a financial
interest in the operation of the entire facility. What name
should be entered as the parent company in Part I,
Section 5.1 of the Form R? Should the facility report
under one holding company name?
B. Answer
The EGF should enter in Part I, Section 5.1 of the Form R
the name of the holding or parent company, consortium,
joint venture, or other entity that owns, operates, or
controls the facility.
(Source: 1998 EPCRA Section 313 Questions and
Answers Document, Question #625 (EPA 745-B-98-
004)).
C. Question
A covered facility sells one of its establishments to a new
owner. The operator of the newly sold establishment,
however, does not change. The same operator operates
the newly sold establishment and the rest of the facility.
Although the facility makes its threshold determinations
based on the activities at the entire facility (including the
newly sold establishment), the facility chooses to report
separately for the different establishments. What parent
name should the newly sold establishment use, the parent
name of the owner or the parent name of the operator
(i.e., the same as the rest of the facility)?
C. Answer
All establishments of a covered facility must report the
parent name of the facility. Therefore, in the instance
described above, the newly sold establishment should use
the parent name of the facility operator (i.e., the same
parent name the rest of the facility is using).
(Source: 1998 EPCRA Section 313 Questions and
Answers Document, Question #626 (EPA 745-B-98-
004)).
D. Question
Two distinct NAICS code operations that are covered
under EPCRA Section 313 (e.g., an electricity generating
unit and a cement plant) are located on adjacent
properties and are owned by the same parent company.
The two operations are operated completely
independently of one another (e.g., separate accounting
procedures, employees, etc.). Are these two operations
considered one facility under EPCRA Section 313?
D. Answer
Yes. Under EPCRA Section 313, a facility is defined as,
"all buildings, equipment, structures, and other stationary
items which are located on a single site or on contiguous
or adjacent sites and which are owned or operated by the
same person." Because these two operations are located
on adjacent properties and are owned by the same person
they are considered one facility for EPCRA Section 313
reporting purposes. Additional information can be found
in the 2015 Toxic Release Inventory Reporting Forms
and Instructions.

Answers Document, Question #9 (EPA 745-B-98-004)).

Appendix F
E. Question
Company A purchases a facility from Company B
between January 1, 2015 and June 30, 2015. For the
2015 reporting year, which company's name and
identification number should appear on the Form R or
Form A submission?
E. Answer
In the case that a facility is purchased between January 1
and June 30, the form submitted for the previous year
must reflect the name used by the facility on December
31 of that reporting year. In this example, company B's
name should appear on the form because it owned the
facility for the duration of the reporting year. The TRI
identification number is location-specific; thus, the
identification number will stay the same even if the
facility changes names, production processes, or NAICS
codes.
With regard to reporting, the owner or operator of the
facility on the annual July 1 reporting deadline (Company
A) is primarily responsible for reporting the data for the
previous year's operations at that facility. However, all
prior owners and operators back to January 1 of the year
covered in the report may also be held responsible if the
current owner or operator does not submit a report.
(Source: 1998 EPCRA Section 313 Questions and
Answers Document, Question #52 (EPA 745-B-98-004)).
F. Question
A piece of contiguous property consists of three covered
sites with various buildings, structures and equipment.
The three sites are owned by two different companies -
Company A and Company B. All three sites operate
completely independently of each other and have separate
personnel, finances, and environmental reporting
systems. Site 1 and its buildings and structures are
owned and operated by Company A and site 3 and its
buildings and structures are owned and operated by
Company B. The middle site, site 2 and its surrounding
buildings and structures, are owned by Company A and
operated by Company B. Are all three sites and their
buildings and structures considered separate facilities
under EPCRA Section 313? Who is responsible for
reporting for each?
F. Answer
Under 40 CFR Section 372.3 a facility is defined as "all
buildings, equipment, structures, and other stationary
items which are located on a single site or on contiguous
or adjacent sites and which are owned or operated by the
same person." Because all buildings and structures
located on sites 1 and 2 are located on contiguous
property and are owned by the same person, they are
considered one facility. Because all buildings and
structures located on sites 2 and 3 are located on
contiguous property and are operated by the same person,
they are also considered one facility. Therefore, for
purposes of determining thresholds, the toxic chemicals
manufactured, processed, and otherwise used at site 2
must be counted toward both Facility A's and Facility
B's threshold determinations. Because the operator is
primarily responsible for reporting, estimating and
reporting releases and other waste management
calculations for sites 2 and 3 are the primary
responsibility of Company B, and the release and other
waste management reporting for site 1 is the primary
responsibility of Company A. EPA allows the release
and other waste management reporting to be done in this
manner to avoid "double counting" releases and waste
management activities at site 2. However, provided
thresholds have been exceeded, if no reports are received
from a covered facility, determinations can be found in
the 2015 Toxic Release Inventory Reporting Forms and
Instructions.

Answers Document, Question #59 (EPA 745-B-98-004)).
Toxics Release Inventory Reporting Forms and Instructions

Appendix G. Trade Secret Submissions
G.1 Instructions for Trade
Secret Submissions
For any EPCRA Section 313 chemical whose identity is
claimed as trade secret, two versions of the substantiation
form must be submitted to EPA as prescribed in 40 CFR Part
350, published July 29, 1988, in the Federal Register (53 FR
28772) as well as two versions of the EPCRA Section 313
report. Trade secret reporting must be done via hard-copy,
paper reporting.
The current substantiation form is available on the TRI
website at: https://www.epa.gov/toxics-release-inventorv-tri-
program/trade-secret-reporting. One set of reports, the
unsanitized version, must provide the actual identity of the
EPCRA Section 313 chemical. The other set of reports, i.e.,
the "sanitized" version, must provide a generic class or
category for the chemical that is structurally descriptive of the
EPCRA Section 313 chemical. If EPA deems the trade secret
substantiation form valid, only the sanitized set of forms will
be made available to the public.
Paper submissions must be sent to both EPA and the state or
the designated official of an Indian tribe and follow the
requirements for reporting trade secrets. If a report is not
received by both EPA and the state (or the designated official
of an Indian tribe), the submitter is considered out of
compliance and subject to enforcement action. Facilities
submitting paper forms must use the corresponding reporting
year forms. These reporting forms can be found on the TRI
website: https://www.epa.gov/toxics-release-inventorv-tri-
program/reporting-forms-and-instructions.
E-mailed submissions will not be accepted.
Form R Reporting
EPA requests that the EPCRA Section 313 chemical, chemical
category, or generic name also be placed in the box marked
"Toxic Chemical, Category, or Generic Name" in the upper
right-hand corner on all pages of Form R. While this space is
not a required data element, providing this information will
help you in preparing a complete Form R report.
Form A Reporting
When making a trade secret claim on a Form A submission,
EPA is requiring that a facility submit a unique Form A for
each EPCRA Section 313 chemical meeting the conditions of
the alternate threshold. Facilities may assert a trade secrecy
claim for a chemical identity on the Form A as on the Form R.
Reports submitted on a per chemical basis protect against the
disclosure of trade secrets. Form As with trade secrecy claims,
like Form Rs with similar claims, will be separately handled
upon receipt to protect against disclosure. Commingling trade
secret chemical identities with non-trade secret chemical
identities on the same submission increases the risk of
disclosure.
All Submissions
A complete report to EPA for an EPCRA Section 313
chemical claimed as a trade secret must include all of the
following:
•	A completed unsanitized version of Form R or Form A
report including the EPCRA Section 313 chemical
identity (staple the pages together); and
•	A sanitized version of a completed Form R or Form A
report in which the EPCRA Section 313 chemical identity
items (Part II, Sections 1.1 and 1.2) have been left blank
but in which a generic chemical name that is structurally
descriptive has been supplied (Part II, Section 1.3) (staple
the pages together); and
•	A completed unsanitized version of a trade secret
substantiation form (staple the pages together); and
•	A sanitized version of a completed trade secret
substantiation form (staple the pages together).
Securely fasten all four reports together.
Some states or tribes also require submission of both sanitized
and unsanitized reports for EPCRA Section 313 chemicals
whose identity is claimed as a trade secret. Others require only
a sanitized version. Facilities may jeopardize the trade secret
status of an EPCRA Section 313 chemical by submitting an
unsanitized version of the EPCRA Section 313 report to a
state agency or Indian tribe that does not require unsanitized
forms. You may identify an individual state or tribe's
submission requirements by contacting the appropriate state or
tribe designated EPCRA Section 313 contact (see Appendix
D).

G.2 Supplemental Form R
and Form A Instructions
The sections below are supplemental instructions to Chapters
C and D for completing hard copy forms submitted with a
trade secret submission.
Part I. Facility Identification
Information
Section 2. Trade Secret Information
2.1	Are you claiming the EPCRA Section 313
chemical identified on Page 2 a trade secret?
The specific identity of the EPCRA Section 313 chemical
being reported in Part II, Section 1 may be designated as a
trade secret. If you are making a trade secret claim, mark
"yes" and proceed to Section 2.2. Only check "yes" if you
manufacture, process, or otherwise use the EPCRA Section
313 chemical whose identity is a trade secret. If you checked
"no," you should submit your non-trade secret form data
electronically using TRI-MEweb.
If facilities wish to report more than one eligible chemical on
the same Form A, then all chemicals included must be non-
trade secrecy claims. Any trade secrecy claims should be
made on a separate form, and then the process is the same as
using the Form R and as described in the following
instructions.
2.2	If "yes" in 2.1, is this copy sanitized or
unsanitized?
Answer this question only after you have completed the rest of
the report. Check "sanitized" if this copy of the report is the
public version that does not contain the EPCRA Section 313
chemical identity but does contain a generic name that is
structurally descriptive in its place, and if you have claimed
the EPCRA Section 313 chemical identity trade secret in Part
I, Section 2.1. Otherwise, check "unsanitized."
4.1 Facility Name, Location, TRI Facility
Identification Number and Tribal Country Name
Facilities filing a trade secret paper form should leave a blank
in the BIA field if the facility is not located within tribal
boundaries.
Location information for a facility that has previously
submitted data to EPA.
Enter your TRIFID in Part I, Section 4.1.
Location information for a facility that has previously
submitted data to EPA, but has changed physical location.
If your facility has moved, do not enter your previously
assigned TRIFID, enter "New Facility". If you are filing a
separate Form R or A for each establishment at your facility,
you should use the same "New Facility" field for each
establishment. If you are uncertain if a TRIFID has been
assigned to your new facility location, use Envirofacts on the
Web to look up the address or facility name at:
http://www.epa. gov/enviro.
Location information for a facility that has changed
ownership, but has not changed physical location.
The TRIFID will always stay with the physical location of a
facility. If a new facility unit moves to this location it should
use this TRIFID. Establishments of a facility (for facilities that
report by part) that report separately should use the TRIFID of
the primary facility.
Location reporting TRI releases for the first time to EPA.
If you are preparing a hard copy TRI form for the first time for
your facility's location and have never reported to TRI in
previous years, you should enter "New Facility" in the space
on the hard copy form designated for the TRI Facility
Identification number (TRIFID).
Part II. Chemical
Identification Information
Section 1. EPCRA Section 313
Chemical Identity (Form R & A)
1.1	CAS Number
You must report the CAS number or category code on your
unsanitized Form R or A and unsanitized substantiation form.
Enter the CAS registry number exactly as it appears in Table
II of these instructions for the chemical being reported. CAS
numbers are cross-referenced with an alphabetical list of
chemical names in Table II. If you are reporting one of the
EPCRA Section 313 chemical categories (e.g., chromium
compounds), you should enter the applicable category code in
the CAS number space. EPCRA Section 313 chemical
category codes are listed below and can also be found in Table
lie.
Do not include the CAS number or category code on your
sanitized Form R or A, or sanitized substantiation form.
1.2	EPCRA Section 313 Chemical or
Chemical Category Name
You must report the specific EPCRA Section 313 chemical
identity on your unsanitized Form R or A and unsanitized

substantiation form. Enter the name of the EPCRA Section
313 chemical or chemical category exactly as it appears in
Table II. If the EPCRA Section 313 chemical name is
followed by a synonym in parentheses, report the chemical by
the name that directly follows the CAS number (i.e., not the
synonym). If the EPCRA Section 313 chemical identity is
actually a product trade name (e.g., Dicofol), the Chemical
Abstracts 9th Collective Index name is listed below it in
brackets. You may report either name in this case.
Do not list the name of a chemical that does not appear in
Table II, such as individual members of an EPCRA Section
313 chemical category. For example, if you use silver
chloride, do not report silver chloride with its CAS number.
Report this chemical as "silver compounds" with its category
code, N740.

Chemical Entering Each
Environmental Medium On-site
(Form R)
5.3 Discharges to Receiving Streams or
Water Bodies
Enter the receiving stream(s) and water body or bodies in
Column A. A total of three spaces is provided on Page 2 of
Form R. If you discharge the EPCRA Section 313 chemical to
more than three streams or water bodies, you should
photocopy Page 2 of Form R as many times as necessary and
then number the boxes consecutively for each stream or water
body. At the bottom of Page 2 you will find instructions for
indicating the total number of Page 2s that you are submitting
as part of the Form R as well as indicating the sequence of
those pages.
Section 6. Transfer(s) of the Toxic
Chemical in Wastes to Off-Site
Locations (Form R)
Number the boxes for reporting the information for each
sequential POTW or other off-site location in Sections 6.1 and
6.2. In the upper left hand corner of each box, the section
number is either 6.1.[ ]._.or 6.2.[ ]. This section is required
only for paper filers (trade secret submissions only); TRI-
MEweb does this task automatically for the reporting facility.
If you report a transfer of the listed EPCRA Section 313
chemical to one or more off-site locations, POTWs, you
should number the boxes in Section 6.1 as 6.1.1, 6.1.2, etc. If
you transfer the EPCRA Section 313 chemical to more than
one POTW, you should photocopy Page 3 of Form R as many
times as necessary and then number the boxes consecutively
for each POTW (e.g., 6.1.2, 6.1.3, etc.). At the bottom of each
page 3 that is submitted, indicate the total number of pages
numbered "3" that you are submitting as part of Form R, as
well as indicating the sequence of those pages. For example,
your facility transfers the reported EPCRA Section 313
chemical in wastewaters to two POTWs. You would
photocopy Page 3 once, indicate at the bottom of each Page 3
that there are a total of two pages numbered "3" and then
indicate the first and second Page 3. The box for the first
POTW on the first Page 3 should be numbered 6.1.1 and while
the box for second POTW on the second Page 3 should be
numbered 6.1.2.
If you report a transfer of the EPCRA Section 313 chemical to
one or more other off-site locations, you should number the
boxes in section 6.2 as 6.2.1, 6.2.2, etc. If you transfer the
EPCRA Section 313 chemical to more than two other off-site
locations, you should photocopy Page 4 of Form R as many
times as necessary and then number the boxes consecutively
for each off-site location. At the bottom of Page 4 you will
find instructions for indicating the total number of Page 4s that
you are submitting as part of the Form R as well as indicating
the sequence of those pages. For example, your facility
transfers the reported EPCRA Section 313 chemical to three
other off-site locations. You should photocopy page 4 once,
indicate at the bottom of Section 6.2 on each Page 4 that there
are a total of two Page 4s and then indicate the first and
second Page 4. The boxes for the two off-site locations on the
first Page 4 would be numbered 6.2.1 and 6.2.2, while the box
for the third off-site location on the second Page 4 should be
numbered 6.2.3. Please note that section 6.2 starts on Page 3
and continues on Page 4.

Section 7. On-Site Waste Treatment,
Energy Recovery, and
Recycling Methods (Form R)
Section 7A: On-Site Waste Treatment Methods
and Efficiency
If your facility performs more than eight sequential waste
treatment methods on a single general waste stream, continue
listing the methods in the next row and renumber
appropriately those waste treatment method code boxes you
used to continue the sequence. For example, if the general
waste stream in box 7 A. la had nine treatment methods applied
to it, the ninth method would be indicated in the first method
box for row 7A.2a. The numeral "1" would be crossed out,
and a "9" would be inserted.
Section 8. Source Reduction and
Waste Management (Form R)
8.10	Did Your Facility Engage in Any Newly
Implemented Source Reduction Activities for
This Chemical During the Reporting Year?
Instructions on how to report source reduction activities on
hard copy From R are provided below.
•	If Your Facility Implemented Source Reduction
Activities. Source reduction activity codes must be
entered in the first column of Sections 8.10.1 through
8.10.4. Next, indicate any methods to identify the
reported source reduction activity using the T-codes
provided below.
•	If you have fewer than four source reduction codes in
Section 8.10, an NA should be placed in the first
column of the first unused row to indicate the
termination of the sequence. If all four rows are used,
there is no need to terminate the sequence.
•	If Your Facility Did Not Implement Source
Reduction Activities. If your facility did not
implement any new source reduction activity for the
reported EPCRA Section 313 chemical, check the
"NA" box in Section 8.10.
8.11	Optional Pollution Prevention
Information
In Section 8.11, you have the opportunity to provide more
detail about activities your facility undertook to reduce
releases of the EPCRA Section 313 chemical, including source
reduction, recycling, energy recovery, treatment or other
pollution controls. EPA encourages you to provide detail in
Section 8.11, as it offers your organization the opportunity to
showcase its achievements in preventing pollution.
While EPA welcomes submissions about recycling and
pollution control activities, the Agency is most interested in
collecting information about innovative and effective source
reduction activities, such as green chemistry or green
engineering practices. In addition, the Agency wishes to
encourage reporters to provide enough detailed information
about their most effective source reduction activities to spur
other facilities to adopt similar practices, as well as to inform
the public about such activities being implemented in their
communities.
To encourage submissions with additional pollution
prevention information, EPA is increasing the prominence and
accessibility of this information. Visit
https://www.epa.gov/tri/p2 to learn how to access this
information (e.g., through the P2 Search tool) and to view
examples of optional pollution prevention information
highlighted in EPA's annual TRI National Analysis report.
The following tips can help you provide meaningful additional
information.
Be Specific:
•	Which processes and products were affected?
•	Which technologies and materials were used?
•	Which release (to air, water land) or waste
management quantities changed?
•	Were there other benefits (e.g., costs, product
quality?)
•	Who provided the idea or assisted with
implementation?
•	Why did you implement this activity?
Enter useful URLs:
•	For equipment manufacturers
•	To other information sources related to the
activity described
A tip-sheet with additional guidance and sample entries can be
found	at
https://www.epa.gov/sites/production/files/documents/tri p2 t
ipsheetpdf. If you wish to provide additional information that
is not related to pollution prevention or other environmentally
friendly practices, use Section 9.1.
Barriers to Implementing Pollution Prevention Activities
Bl. Insufficient capital to install new source reduction
equipment or implement new source reduction
activities/initiatives.
B2. Require technical information on pollution
prevention techniques applicable to specific
production processes.
B3. Concern that product quality may decline as a result
of source reduction.
B4. Source reduction activities were implemented but
were unsuccessful.
B5. Specific regulatory/permit burdens

B6. Pollution prevention previously implemented-
additional reduction does not appear technically or
economically feasible.
B7. No known substitutes or alternative technologies.
B8. Other barriers.
EPA believes this information is valuable in giving a full
picture of the source reduction activities your facility engages
in and what barriers you face in the implementation of source
reduction activities. EPA also believes this information may
allow for an exchange between those that have knowledge of
source reduction practices, such as the EPA P2 Program, and
those that are seeking additional help. In addition, it will better
enable EPA to identify those technological areas for which
EPA can support basic research to identify alternative
technologies that are less polluting.
Section 9. Miscellaneous Information
(Form R)
9.1 Miscellaneous, Optional, and Additional
Information for Your Form R Report
Your facility may provide additional information pertaining to
any portion of your Form R submission in the box provided in
the free text box provided. Your submissions to Section 9.1
regarding miscellaneous, additional, optional information may
provide the Agency and/or the public with useful data that
helps explain why your facility submitted data in one or more
data elements that might appear unusual or inconsistent with
previous TRI Form R submissions or with other data supplied
by your facility during this reporting year. Such additional
data may help EPA reduce the need for additional data quality
control as well as additional TRI-related enforcement and
compliance efforts.
EPA suggests you consider the following topics should you
provide optional information in the 9.1 box:
•	Changes in Production Levels
•	Calculation Methods, e.g., Emission Factors
•	One-time or Intermittent Events Impacting Reported
Quantities
•	Issues or Difficulties Encountered in Submitting
Form
•	Other Regulatory Requirements Related to This
Chemical
•	No TRI Reports Expected for This TRIFID Next
Year
•	No TRI Report Expected for This Chemical Next
Year
Do not submit information you consider to be CBI or
otherwise protected on your Form R.
