BACKGROUND
The purpose of this document, "Reporting
Requirements for Continuous Releases of Hazardous
Substances - A Guide for Facilities on Compliance"
(Guide), is to help you understand the definitions and
requirements contained in the U.S. Environmental
Protection Agency's (EPA's) Final Rule on "Reporting
Continuous Releases of Hazardous Substances" (55
Federal Register 30166) published on July 24, 1990,
which amended 40 Code of Federal Regulations Parts
302 and 355. The Continuous Release Rule provides
a reduced reporting option for facilities that release
hazardous substances in a manner that is continuous,
and stable in quantity and rate. This Guide has been
designed to provide facilities who choose this reduced
reporting option with the information necessary to
successfully comply with the continuous release
reporting.
The Guide is divided into two parts. Part 1 provides
general information in a question and answer format
regarding the Continuous Release Rule and the
responsibility of the person in charge of a facility to
report releases of hazardous substances. Part 2
contains detailed instructions on how to prepare
continuous release reports that include all of the
information required to qualify for reduced reporting
under the Rule. Although the Rule applies to both
facilities and vessels, because the reporting elements
from vessels are somewhat different from those of
facilities (e.g., vessels by their nature do not have a set
location), this Guide will only address the reporting
requirements for facilities. Much of the information in
this Guide is applicable to vessels, however, persons in
charge of vessels who wish to report under the
Continuous Release Rule should contact EPA to
discuss vessel-specific requirements in detail.

PART 1: REPORTING REQUIREMENTS FOR CONTINUOUS RELEASES
OF HAZARDOUS SUBSTANCES
1.0 Introduction
Part 1 of the Reporting Requirements for
Continuous Releases of Hazardous Substances - A
Guide for Facilities on Compliance (Guide) explains
the general reporting (notification) requirements of the
Comprehensive Environmental Response,
Compensation, and Liability Act of 1980 (CERCLA)
and the Emergency Planning and Community Right-
to-Know Act (EPCRA) for hazardous substances, as
well as a number of relevant terms. In addition, it
provides information on what qualifies as a continuous
release under the Rule, and describes the continuous
release reduced reporting requirements in detail,
including how, when, and to whom such releases must
be reported.
1.1 CERCLA and EPCRA Release
Reporting Requirements
Section 103(a) of CERCLA "as amended" and
EPA's implementing regulations (40 Code of Federal
Regulations (CFR) 302.8) require the person in charge
of a facility to immediately notify the Federal
government (the National Response Center or NRC)
whenever a reportable quantity (RQ) or more of a
CERCLA hazardous substance is released unless the
release is federally permitted. The purpose of this
requirement is to notify officials of potentially
dangerous releases so that they can evaluate the need
for a response action. CERCLA hazardous substances
are defined in Section 101(14) of CERCLA and
include over 800 specific CERCLA listed substances
(40 CFR 302.4), as well as, hazardous substances that
have been defined under other statutes.
Likewise, Section 304 of EPCRA (also known as
Title III of the Superfund Amendments and
Reauthorization Act (SARA)) and EPA's
implementing regulations (40 CFR 355.40) require the
owner or operator of a facility to immediately notify
state and local officials whenever an RQ or more of a
CERCLA hazardous substance is released. These
same Sections also require the owner or operator of a
facility to immediately notify state and local authorities
whenever there is a release of an RQ or more of any of
the 356 listed Extremely Hazardous Substances
(EHSs); approximately 222 of these EHSs are not
CERCLA hazardous substances, but are non-CERCLA
EHSs. Notifications under Section 304 of EPCRA must
be given both to the local emergency planning
committee (LEPC) of any area likely to be affected by
the release and to the state emergency response
commission (SERC) of any state likely to be affected
by the release. If the release is located on Tribal lands
and a Tribal Emergency Response Commission
(TERC) exists, notification must be given to the
appropriate TERC. For the purposes of this Guide, all
references to requirements for reporting to SERCs and
LEPCs under EPCRA should be construed to include
the same requirements for reporting to TERCs, if
appropriate.
The reporting requirements between CERCLA
and EPCRA are slightly different. These differences
are outlined in Exhibit 1-1 and are reviewed in the
following sections.
What is a facility?
A "facility" is defined under CERCLA to include
any building, structure, installation, equipment, pipe or
pipeline, well, pit, pond, lagoon, impoundment, ditch,
landfill, storage container, motor vehicle, rolling stock,
or aircraft or any site or area where a hazardous
substance has been deposited, stored, disposed of or
placed, or otherwise come to be located. There may be
one or more facilities at a particular site. For example,
a site may be comprised of four facilities including one
building, one lagoon, and two storage containers.
The definition of the term "facility" under
EPCRA differs from the CERCLA definition. Under
Section 329(4) of EPCRA, a facility is defined as all
buildings, equipment, structures, and other stationary
items that are located on a single site or on contiguous
or adjacent sites that are owned and controlled by the
same person. For emergency release reporting, the
EPCRA definition of facility also includes motor
vehicles, rolling stock, and aircraft.

When does a hazardous substance release occur?
Under CERCLA, a "release" occurs when a
hazardous substance enters the environment. A key
element of the definition of release is the phrase "into
the environment." The environment includes all
media: air, land (surface or subsurface strata), surface
water, and ground water (including drinking water
supply). Examples of hazardous substances released
into the environment include: releases from pipes onto
the ground; releases from stacks into the air; or other
uncontained discharges. If such a release of a
CERCLA hazardous substance occurs in a quantity
that equals or exceeds an RQ in a 24-hour period, it
must be reported immediately to the NRC.
The definition of a release is similar under
EPCRA, however generally EPCRA reporting
requirements do not apply if the release results in
exposure to persons solely within the facility (i.e., site)
boundaries. Releases of CERCLA hazardous
substances and EHSs in quantities that equal or exceed
an RQ must also be reported to the SERC and LEPC.
What is a reportable quantity?
Each CERCLA hazardous substance is assigned
an RQ. When an RQ or more of a CERCLA
hazardous substance is released from a facility during
a 24-hour period, it triggers the reporting requirements
of Section 103 of CERCLA. An RQ is not an absolute
measure of the risk associated with the hazardous
substance; the purpose of an RQ is to trigger the
reporting of a hazardous substance release. The actual
risk posed to human health and the environment will
vary with the circumstances of the particular release;
many factors other than the size of the release may
influence the risk and thus the need for a government
response. Except for radionuclides (which are
expressed in curies), the RQ is expressed in pounds
(i.e., 1 lb, 10 lbs, 100 lbs, 1000 lbs, 5000 lbs). You
can find a list of hazardous substances and their
associated RQs in the CFR in Table 302.4 at 40 CFR
Part 302.
EHSs that are not CERCLA hazardous
substances (i.e., non-CERCLA EHSs) are assigned
reporting triggers (RQs) under Section 304 of EPCRA.
RQs for non-CERCLA EHSs were adjusted on May
7, 1996 at 61 FR 20473 and are in 40 CFR Part 355.
EPCRA
2
-------
Section 304 requires that any release of an EHS that
equals or exceeds an RQ established under either
CERCLA or EPCRA be reported immediately to the
appropriate SERC and LEPC.
How are releases of CERCLA hazardous substances
reported?
Generally, CERCLA Section 103(a) requires the
person in charge of a facility to notify the NRC
immediately if that person has knowledge that an RQ
or more of a hazardous substance has been released
from the facility within a 24-hour period. To
determine whether an RQ or more of a specific
CERCLA hazardous substance has been released
within a 24-hour period, the person in charge must
consider the amount released from all sources at the
facility and determine if together the release of the
hazardous substance equals or exceeds an RQ. For
example, if a facility has three sources, each releasing
1/3 of an RQ of a CERCLA hazardous substance X
over the same 24-hour period, and the release of
hazardous substance X is not federally permitted, the
person in charge must report that release to the NRC.
(The NRC's telephone number is listed on page 15 of
this Guide).
The EPCRA Section 304 reporting requirements
parallel the CERCLA notification requirements, but
apply to the owner or operator of a facility, and are
intended to make release information available
immediately to state and local authorities. For the
purposes of EPCRA, to determine whether an RQ or
more of a CERCLA hazardous substance or EHS has
been released over a 24-hour period, the owner or
operator must consider the amount released from all
sources at the facility and determine if together the
release of the hazardous substance equals or exceeds
an RQ. For example, if a facility has three sources,
each releasing 1/3 of an RQ of a CERCLA hazardous
substance or non-CERCLA EHS X over the same 24-
hour period, and the release of hazardous substance X
is not federally permitted, the person in charge must
report that release to the appropriate SERC and LEPC.
You can obtain the telephone numbers for appropriate
state authorities (SERC) and local authorities (LEPC)
by calling the RCRA/Superfund/EPCRA Hotline. See
page 15 of this Guide for telephone numbers.
The primary reason for these notification
requirements is to alert government officials to releases
of CERCLA hazardous substances and EHSs that may
require a timely response action to prevent or mitigate
damage to public health or welfare or the environment.
1.2 Continuous Releases
What is the continuous release reduced reporting
option?
CERCLA Section 103(f)(2) and EPA's
implementing regulations at 40 CFR Parts 302 and
355, provide a special reduced reporting option for
"continuous" releases of CERCLA hazardous
substances and EHSs. This CERCLA and EPCRA
reporting relief applies to facilities that release
CERCLA hazardous substances or EHSs that are
"continuous" and "stable in quantity and rate" under
the regulatory definition of 40 CFR 302.8(b). For
these types of releases, reporting facilities can choose
either to: 1) report on a per occurrence basis, or 2)
report as a "continuous" release in accordance with the
Continuous Release Rule, "Reporting Continuous
Releases of Hazardous Substances" (55 FR 30166)
published on July 24, 1990, which amended 40 CFR
Parts 302 and 355.
The purpose of CERCLA Section 103(f)(2) is to
reduce reporting of predicable release notifications.
CERCLA Section 103(f)(2), however, does not
eliminate the requirement to report. Government
response officials need to receive some notification of
each hazardous substance release that equals or
exceeds an RQ on a continuous basis, so that the
release can be evaluated and if necessary, a response
action can be taken.
What is a continuous release?
A "continuous release" is a release of a hazardous
substance that is "continuous" and "stable in quantity
and rate" under the regulatory definitions of these
terms listed in Exhibit 1-2. A continuous release may
be a release that occurs 24 hours a day (e.g., a radon
release from a stockpile) or a release that occurs during
a certain process (e.g., benzene released during the
production of polymers) or a release that occurs
intermittently (e.g., the release of a hazardous
substance from a tank vent each time the tank is
filled).
3
-------
EXHIBIT 1-2: DEFINITIONS
Continuous. A continuous release is a release
that occurs without interruption or abatement, or
that is routine (i.e., occurs during normal
operating procedures or processes), anticipated,
intermittent, and incidental to normal operations.
Stable in quantity and rate. A release that is
stable in quantity and rate is a release that is
predictable and regular in the amount and rate of
emission.
Some releases resulting from malfunctions may
also qualify for reduced reporting as continuous
releases under Section 103(f)(2) if they are incidental
to normal plant operations or treatment processes, are
stable in quantity and rate, and either (1) occur without
interruption or abatement or (2) are routine,
anticipated, and intermittent. For example, fugitive
emissions from valves that occur at different rates over
the course of a production cycle may be a malfunction
that qualifies for reduced reporting. The determinative
question of whether any release, including a
malfunction, qualifies for reporting under Section
103(f)(2) is whether the release satisfies the definitions
of "continuous" and "stable in quantity and rate."
Releases must be sufficiently predictable and
regular so that the person in charge, or the owner or
operator of the facility can provide a full description of
the release to government authorities. Upon receipt of
continuous release information, government officials
will evaluate the risk associated with the release and
determine the need for a response action.
Do releases that result from unanticipated events
qualify for reduced reporting as continuous
releases?
Releases of CERCLA hazardous substances that
are the result of unanticipated incidents do not qualify
for reduced reporting under Section 103(f)(2). Such
episodic incidents include spills, equipment failures, or
the emergency shutdown of equipment. Also included
are releases from malfunctions that are not continuous
or stable, such as pipe ruptures. Although these
releases may occur with some regular statistical
frequency, unanticipated incidents by their nature do
not produce releases that are continuous or sufficiently
regular or predictable in quantity and rate to satisfy the
requirements for reporting them as continuous
releases. If you are aware that such an episodic release
of a CERCLA hazardous substance has occurred in a
quantity equal to or greater than an RQ, you must
report the release immediately to the NRC, SERC, and
LEPC.
How do you handle simultaneous continuous
releases from several sources and determine
whether such releases must be reported?
To determine whether a hazardous substance
release is reportable under CERCLA, you must identify
whether the release equals or exceeds an RQ. If your
facility is releasing a hazardous substance from several
sources simultaneously, you must aggregate the
releases of the hazardous substance across all of the
facility's sources to determine whether an RQ or more
of a hazardous substance has been released from your
facility.
If you release an RQ or more of the same
CERCLA hazardous substance from more than one
facility (e.g., building, surface impoundment, or
lagoon), the Continuous Release Rule (40 CFR
302.8(1)) provides you with two reporting options
under CERCLA. To meet the requirements of
CERCLA, you may either: 1) aggregate multiple
concurrent releases of the same hazardous substance
from contiguous or adjacent facilities and report them
in a single notification; or 2) consider releases from
each facility separately and submit separate reports on
a facility-specific basis. Under EPCRA the definition
of facility includes all "buildings, equipment,
structures, and other stationary items that are located
on a single site or on contiguous or adjacent sites that
are owned and controlled by the same person"
therefore, all releases from contiguous or adjacent
facilities are, by definition, aggregated. For the
purposes of EPCRA, these items must be reported as
one facility.
Although under CERCLA you may select either
option for reporting continuous releases, whichever
option you select must be used for all continuous
release reporting. For example, if you report releases
on a facility-specific basis, statistically significant
increases (SSIs) in the release must also be reported on
a facility-specific basis. If you select the option of
aggregating releases from contiguous or adjacent
facilities and reporting them in a single notification,
you may have a single SSI trigger for all the releases.
4
-------
How do you establish a basis for reporting releases
as continuous?
To qualify a release for reporting as a continuous
release, you must establish a basis for asserting that the
release is continuous and stable in quantity and rate.
The Continuous Release Rule provides you with
flexibility in establishing this basis. You may report
the release to either the NRC (for CERCLA hazardous
substances) or the appropriate SERC and LEPC (for
CERCLA hazardous substances and non-CERCLA
EHSs) on a per-occurrence basis for the period of time
necessary to establish that the pattern of the release is
continuous and stable. However, if you have a
sufficient basis for establishing the continuity,
quantity, and regularity of a release, multiple reports
are not necessary. A one-time telephone call to each of
the appropriate authorities (the NRC, SERC, and
LEPC for CERCLA hazardous substances, or only the
SERC and LEPC for non-CERCLA EHSs) will alert
them to your intent to report the release as a
continuous release.
You may establish the pattern of the release by
relying on past release data, engineering estimates,
your knowledge of the facility's operations and release
history, or your best professional judgment.
Monitoring data are not required. Regardless of which
method is used, however, all estimates reported for a
particular release must have a sound technical basis.
The basis for asserting that the release is continuous
and stable in quantity and rate will be included in your
written report.
Are the reporting requirements different under
CERCLA and EPRCA?
The reporting requirements for CERCLA and
EPCRA are slightly different. CERCLA covers only
CERCLA hazardous substances. EPCRA covers both
CERCLA hazardous substances, and EPCRA EHSs
(EPCRA EHSs are made up of some CERCLA
hazardous substances and some non-CERCLA
hazardous substances).
CERCLA hazardous substances must be reported:
1) in accordance with CERCLA, to the NRC; 2) in
accordance with EPCRA, to the appropriate SERC and
LEPC. Those listed EHSs which are also CERCLA
hazardous substances fall under both CERCLA and
EPCRA and must also be reported to the NRC, SERC,
and LEPC.
Non-CERCLA EHSs (those EHSs which are not
covered under CERCLA) are governed by EPCRA and
so must only be reported to the appropriate SERC and
LEPC. The remainder of this Guide will discuss
reporting requirements to the NRC, SERC, and LEPC
in detail, and these requirements will also be
illustrated in several exhibits. However, it is
important to remember that in all cases non-CERCLA
EHSs need not be reported to the NRC.
Exhibit 1-1, on page 2, explains the different
reporting requirements under CERCLA and EPCRA,
including the definition of facility, the relevant
chemical list, notification requirements, and
constituents of a release.
What reporting is required for continuous releases
of CERCLA hazardous substances?
Although Section 103(f)(2) provides for reduced
reporting of continuous releases, it does not eliminate
the need to report such releases. The continuous
release reporting requirements for CERCLA hazardous
substances are described in detail in Section 1.2 -
Reporting Continuous Releases. The different types of
continuous release telephone notification and written
reports are explained more fully on the following
pages. There are three standard reporting
requirements: the initial telephone notification; the
initial written report; and the written first anniversary
follow-up report. In all cases, each facility must
submit these reports. These main reporting
requirements are outlined in Exhibit 1-3 on page 6. In
addition to the standard reporting requirements, there
are three additional reports for special circumstances:
a report of an SSI and two types of reports of changes
in previously submitted continuous release
information. These special reports will only be
submitted by those facilities that encounter these
particular situations. The additional circumstantial
reporting requirements are outlined in Exhibit 1-4 on
page 8. Exhibit 1-5, on page 10, outlines where to
submit continuous release reports for release of
CERCLA hazardous substances. In addition, to help
you understand the reporting requirements of the Rule,
Part 2 of this Guide contains specific procedures and
instructions for complying with the requirements for
CERCLA hazardous substances.
What reporting is required for non-CERCLA
EHSs?
Releases of non-CERCLA EHSs may qualify as
continuous releases as long as they satisfy the
regulatory definitions in the Continuous Release Rule.
Therefore, continuous releases of non-CERCLA EHSs
are entitled to reduced reporting requirements under
5
-------
EPCRA. The continuous release notification
requirements for such releases are slightly different
from the requirements for releases of CERCLA
hazardous substances as described below.
If your facility has a continuous release of a non-
CERCLA EHS, you must establish the release as
continuous and stable in quantity and rate by making
an initial telephone call to the appropriate SERC and
LEPC, and by submitting an initial written report to
the SERC and LEPC. These notifications will provide
state and local response officials with sufficient
information to assess the release and to determine
whether it qualifies for reduced reporting.
Additional circumstantial reporting requirements
for non-CERCLA EHSs that are continuous and stable
in quantity and rate include immediate reporting of
SSIs and reporting changes in the source or
composition of the release. Under the requirements of
EPCRA Section 304, you must submit a written
follow-up notice to the SERC and LEPC within 30
days of a report of an SSL
Exhibit 1-6, on page 11, illustrates to whom you
must submit each type of continuous release report for
releases of non-CERCLA EHSs. For a summary of the
information required in the reports you must submit
for continuous releases, please refer to Part 2.
1.3 Reporting Continuous Releases
What are the standard requirements for reporting
a continuous release of a hazardous substance?
There are three steps in the standard continuous
release reporting process. Each step in the process
involves a different type of continuous release
notification. The three types of notification required to
report a CERCLA hazardous substance are
summarized in Exhibit 1-3. The reporting
requirements for non-CERCLA EHSs are slightly
different and will be addressed in detail in the
following sections.
To begin the reporting process for continuous
releases, you must have a sufficient basis for
establishing that the release is continuous and stable in
quantity and rate. Once such a basis has been
established, the initial telephone notification should be
made.
EXHIBIT 1-3:
STANDARD REPORTING
REQUIREMENTS
The reporting requirements for continuous
releases of CERCLA hazardous substances are:
Step 1 Initial telephone notification to
the NRC, SERC, and LEPC;
Step 2 Initial written report to the
EPA Regional Office, SERC, and
LEPC; and
Step 3 A one-time first anniversary follow-up
report to the EPA Regional Office.
Step 1: Initial Telephone Notification
For CERCLA hazardous substances, you must
make an initial telephone call to three separate
government authorities: the NRC, the appropriate
SERC, and the appropriate LEPC. For non-CERCLA
EHSs, you need only call the appropriate SERC and
LEPC. In either case, the initial telephone calls will
alert authorities to your intent to report a release as a
continuous release. When calling, please be certain
that your intent is clear to those receiving your
telephone call. See Part 2 of this Guide for a summary
of the information that must be provided to
government officials in the initial telephone call.
How will EPA identify continuous release reports?
If you are reporting a release of a CERCLA
hazardous substance, when you make the initial
telephone notification, the NRC will assign a case
number to your release report. This case number will
become EPA's identifier for your facility. EPA calls
this number your facility's CR-ERNS number. You
must use this CR-ERNS number on all future release
reports or correspondence related to continuous
releases from your facility. The CR-ERNS number
will identify your facility and will enable EPA to link
all reports about releases from your facility. If you
misplace your CR-ERNS number, contact the
appropriate EPA Regional Office and provide
information identifying your facility.
6
-------
Since your facility has only one overall
"continuous release" (which may be made up of a
number of individual continuous releases of hazardous
substances from a number of sources) your facility
should have only one CR-ERNS number. Once
assigned to your facility, the CR-ERNS number will
not change with different release reports such as the
follow-up report, statistically significant increase
reports, and changed release reports.
If you are reporting a release of a non-CERCLA
EHS, since you do not report to the Federal authorities
you will not receive a CR-ERNS number. CR-ERNS
numbers are only used by EPA to track your
continuous release. Since a release of a non-CERCLA
EHS will not be reported to EPA, and since your SERC
and LEPC will use their own methods to track your
release, no CR-ERNS number is required for a release
of a non-CERCLA EHS.
If you elect to aggregate multiple concurrent
releases of CERCLA hazardous substances from
adjacent or contiguous facilities for purposes of
reporting continuous releases, you will be assigned
only one CR-ERNS number for your aggregated
release in your initial telephone call. This number will
be the CR-ERNS number for the entire site and should
be used on all subsequent release reports and
correspondence.
If you misplace your CR-ERNS number, contact
your EPA Regional Office (see pages 14 and 15 for
telephone numbers), provide information identifying
your facility, and the EPA Regional Office will provide
you with your CR-ERNS number.
Step 2: Initial Written Report
Within 30 days of the initial telephone
notification, you are required to submit an initial
written report to the appropriate EPA Regional Office,
SERC, and LEPC (for releases of CERCLA hazardous
substances) and to only the appropriate SERC and
LEPC (for releases of non-CERCLA EHSs). (See
pages 14 and 15 for a listing of the addresses of the
EPA Regional Offices.) The purpose of this report is
to confirm your intent to report your release as a
continuous release under Section 103(f)(2), and to
provide government response officials with sufficient
information about your release to enable them to
determine if the release qualifies as a continuous
release. The information will also allow government
officials to identify the potential risks associated with
the release.
The initial written report must include specific
information about each source of the continuous
release. This information should include: a brief
statement describing the basis for asserting that the
release is continuous and stable in quantity and rate;
hazardous substance information; the environmental
medium affected (i.e., air, surface water, soil, or
ground water); and certain ecological and population
density information. A detailed discussion of the
requirements of the initial written report is provided in
Part 2 of this Guide.
To assist you in preparing both the initial written
report and the one-time first anniversary follow-up
report discussed below, EPA has included a Suggested
Continuous Release Reporting Format as Appendix
B of this Guide. Using the format will ensure that you
have provided EPA with all the information required
to properly assess your continuous release report. This
format is also available electronically for EPA
Regional Offices. An example of a properly
Completed Suggested Continuous Release Reporting
Format can be found in Appendix D.
Step 3: First Anniversary Follow-up Report
For reports of releases of CERCLA hazardous
substances, within 30 days of the first anniversary of
your initial written report, you are required to reassess
your initial continuous release report and gather the
information on all of the reported substances being
released. After doing this, you must submit a one-
time, written first anniversary follow-up report to the
appropriate EPA Regional Office. Please note that the
first anniversary follow-up report must be sent to the
appropriate EPA Regional Office for all reports of
CERCLA hazardous substances, but is not required for
reports of non-CERCLA EHSs.
The information required in the written follow-up
report is identical to that required in the initial written
report, but it should be based on release data gathered
over the year (i.e., during the period since the
submission of the initial written report). The principal
purpose of the follow-up report is to update and
confirm the information submitted in the initial
written report, thereby providing government
authorities with a more accurate baseline against
which to evaluate the risks associated with the
7
-------
continuous release. After you have submitted the
follow-up report to the EPA Regional Office, you are
responsible for reassessing the release annually, but
you are not required to notify EPA of each
reassessment unless there is a change in the
information previously submitted to EPA.
Are there additional continuous release reporting
requirements?
There are two additional types of continuous
release reporting requirements: a requirement for
notification of an SSI and requirements for notification
of changes to previously submitted continuous release
information. These reports are used during specific
circumstances and are illustrated in Exhibit 1-4.
EXHIBIT 1-4: CIRCUMSTANTIAL
REPORTING REQUIREMENTS
There are two types of additional
reporting requirements for continuous
releases of CERCLA hazardous
substances that are only used during
specific circumstances. These
requirements are:
(1) Notification of an SSI:
- Immediate notification of an
SSI to the NRC, SERC, and
LEPC.
(2) Notification of a change in
previously submitted release
information. Either:
- Notification of a change in
source or composition,
which is treated as if it
were a new release (i.e.,
with a telephone call to the
NRC, SERC, and LEPC,
followed by a written report
and a first anniversary
follow-up report); or
- For CERCLA substances
only, notification of any
other type of change (e.g.,
a change in facility
ownership) in a written
letter to only the EPA
Region.
Statistically Significant Increase Notifications
An SSI is any episodic release of a hazardous
substance that exceeds the release quantity delineated
in the upper bound of the normal range of the facility's
continuous release report. The normal range is defined
to include all the releases of a hazardous substance
(from all sources) occurring over any 24-hour period
under normal operating conditions during the
preceding year. Only those releases that are both
continuous and stable in quantity and rate may be
included in the normal range. The aggregated upper
8
-------
bounds of the normal range of each hazardous
substance is referred to throughout this Guide as the
"SSI trigger." A detailed explanation of the SSI
trigger and instructions for calculating the trigger are
included in Part 2 of this Guide.
An SSI in a continuous release of a CERCLA
hazardous substance must be reported to the NRC,
SERC, and LEPC as soon as the person in charge is
aware that the release exceeds the SSI trigger. SSIs in
a continuous release of a non-CERCLA EHS must be
reported to the appropriate SERC and LEPC. Because
an SSI is a type of episodic release, it is treated as such
by the NRC.
The NRC may provide you with an SSI number.
This number is not to be confused with your facility's
CR-ERNS number. When reporting an SSI, the caller
should anticipate that the NRC will ask for
information that is similar to what is asked when a
person reports any other episodic release incident. SSI
reports to the NRC must include the CR-ERNS
number assigned to
the facility by the NRC during the original initial
telephone notification.
Please note that, it may be possible to adjust the
SSI trigger (i.e., change the normal range of the
release) if a particular continuous release frequently
exceeds the upper bound of the normal range. Specific
procedures for modifying the SSI trigger for a
hazardous substance are contained in Part 2.
Changes in Previously Submitted Release
Information
There are two types of reports of changes in
previously submitted release information: reports of a
change in source or composition; and reports of
changes in other information.
How do you report changes in source or
composition?
If there is a change in the source or composition
of your continuous release of a CERCLA hazardous
substance, the release is considered a "new" release. A
change in the source or composition of a release may
be caused by such factors as equipment modifications
or process changes. To continue reporting the release
under CERCLA Section 103(f)(2), you must establish
the new release as continuous and stable in quantity
and rate, with an initial telephone call to the NRC,
SERC, and LEPC and, within 30 days, submit an
initial written report to the appropriate EPA Regional
Office, SERC, and LEPC. When telephoning the
NRC, clearly identify the release as a change in the
source or composition of a previously reported release
and for reports of releases of CERCLA hazardous
substances, provide the CR-ERNS number assigned by
the NRC in your original initial telephone call. As
with your original continuous release report, you must
submit a first anniversary follow-up report to the EPA
Region for any changes in source or composition of
CERCLA hazardous substances.
If there is a change in source or composition of
your continuous release of a non-CERCLA EHS, it is
also considered a new release. An initial telephone
call must be made to the appropriate SERC and LEPC,
followed by an initial written report.
How do you report changes in other information?
For all other changes (i.e., changes other than in
the source or composition) in the information
submitted in any initial written or follow-up report for
releases of CERCLA hazardous substances, you must
notify the EPA Regional Office by letter within 30 days
of determining that the information previously
submitted is no longer accurate. Although notification
of the SERCs and LEPCs for either CERCLA
hazardous substances or non-CERCLA EHSs is not
required by the Continuous Release Rule, SERCs and
LEPCs should be notified of these changes to properly
update the facility's file.
Examples of changes in other information
include: changes in the facility ownership; changes in
the identity of the person in charge of the facility; or
changes in the sensitive populations and ecosystems.
All notifications of changes in releases of CERCLA
hazardous substances must include the original CR-
ERNS number assigned to the facility by the NRC in
the initial telephone notification. You must also
9
-------
include a signed statement with the notification verifying that all reported
information on the release submitted to date is accurate and current. A
similar signed statement is required in all written correspondence pertaining
to the continuous release. For an example of the statement required under the
Rule, see Part 2 of this Guide.
1.4 Recordkeeping Requirements
What are my recordkeeping responsibilities as a person in charge of a
facility?
To satisfy the specific requirements for reporting continuous releases,
you are responsible for estimating or calculating the quantities of all
continuous releases that you report by whatever methods are appropriate. As
stated above, this may involve reliance upon past release data, engineering
estimates, knowledge of plant operations and release history, your best
professional judgment, or any other method that has a sound technical basis.
All estimates, however, must have a sound technical basis.
In addition, you must keep the information substantiating the estimates
you have reported on file at your facility. Supporting materials must be kept
on file for a period of one year and should substantiate the normal range of
the release, the basis for asserting that the release is continuous and stable in
quantity and rate, and the other information included in the initial written
report, the follow-up report, or the most recent annual evaluation. EPA may
question the basis for your determination that a release is continuous and
stable or any other submitted information, and may ask to review the
substantiating information. It is important, therefore, to keep an accurate
account of the history of all continuous releases at your facility and evaluate
these releases carefully for changes, and for SSIs as well.

1. A change of previously submitted release information (i.e., source or composition) is treated like a "new release". Therefore, for reports of CERCLA hazardous
substances, the person in charge of the facility must first make an initial telephone notification to the NRC, SERC, and LEPC to report the change. The facility must
then send a written report to the SERC, LEPC, and appropriate EPA Regional Office. Within 30 days of the first anniversary of the Initial Report, for reports of
releases of CERCLA hazardous substances, the facility must send a follow-up report to the appropriate EPA Regional Office.
2. A change in other information is usually a change in general information regarding the facility (i.e., a change in the person in charge of the facility or sensitive
population). According to the Rule, a facility is only required to submit a letter to the appropriate EPA Regional Office stating these changes. Although a facility is
not required to submit the changes to the SERC and LEPC, it is recommended that a reporting facility do so in order to properly update the facility's files.

-------
1.5 EPA's Role in the Continuous
Release Reporting Process
How will continuous release information be
processed?
When EPA receives the CERCLA hazardous
substance continuous release information, the Agency
will create a file for your facility. The information you
submit in the initial written and first anniversary
follow-up report will be entered into the Continuous
Release - Emergency Response Notification System
(CR-ERNS) database. EPA will also enter any reports
of changes in the release into CR-ERNS. CR-ERNS is
a central depository for all continuous release
information received by the NRC and the EPA
Regions. Information in CR-ERNS will be stored in a
national database at the John A. Volpe National
Transportation Systems Center (VNTSC) in
Cambridge, MA.
How will EPA evaluate the potential threat posed
by a continuous release?
The potential threat posed by a continuous
release of a hazardous substance is determined by
assessing its toxicity, the quantity and frequency of the
release, and the proximity and nature of the potentially
exposed population and environment. EPA will
evaluate the health and environmental risks posed by
continuous releases. Information from written reports
will be combined with toxicity information on the
hazardous substance(s) released to generate risk
estimates for each release. It is important, therefore,
that the information you report is as accurate as
possible. If data elements are missing, EPA will be
forced to use conservative estimates.
What assistance will be provided by EPA
throughout the reporting process?
EPA has included a Suggested Continuous
Release Reporting Format for written reports located
in Appendix B of this Guide. This suggested Format
is designed to assist you in completing the written
reports and ensuring that all of the required
information is included in your written reports.
In addition, on page 19 of this Guide, you can
find Exhibit 2-1, a checklist of the information
required in the initial written report and first
anniversary follow-up reports. This checklist provides
an overview of the information required and is another
means that you can use to verify that all required
information has been collected and submitted.
In addition to the detailed explanation of the
specific continuous release reporting requirements
contained in this Guide, your EPA Region or the
RCRA/Superfund/EPCRA Hotline (telephone numbers
are provided on pages 14 and 15) can also provide
assistance in understanding and complying with all
reporting requirements.
What actions may EPA take in response to
continuous release reports?
Under CERCLA, EPA has authority to evaluate
and respond to releases of hazardous substances. EPA
can rely on the broad response authority available
under CERCLA Sections 104, 106, and 107 to respond
to continuous releases, as well as episodic releases.
The actions EPA may choose to take include, but are
not limited to, the following:
If EPA has doubts or questions about any portion
of your report or about the basis reported for
establishing a release as continuous, you may be
asked to clarify your report or to submit
additional information;
If you have not already done so, EPA may
request that you establish a release as continuous
and stable by reporting it for some period of time
on a per-occurrence basis under CERCLA
Section 103(a);
EPA may alert a permit program office or other
office that a release from your facility merits
further evaluation and possible response action;
or
EPA may decide to perform a site inspection or
field response at your facility.
If the person in charge of a facility does not receive
comments from EPA regarding a continuous release
report, should it be assumed that the report is
approved?
EPA's receipt of a continuous release report
without comment does not indicate approval of the
report or the information it contains. EPA, SERCs,
and LEPCs may re-evaluate the information submitted
13
-------
in any continuous release report at any time, and may
contact the person in charge of the facility to review
the basis for reporting the release as a continuous
release under Section 103(f)(2). There is no time limit
for EPA's review.
1.6 Additional Questions
Can the Toxic Release Inventory form be used to
satisfy continuous release reporting requirements?
To minimize any possible duplication in the
reporting process, the Continuous Release Rule allows
you to submit the EPCRA Section 313 Toxic Release
Inventory (TRI) Form R as a substitute for the written
initial or follow-up report, provided that you include
certain additional required continuous release
information. This additional information will provide
EPA with details about the continuous release that are
not available from the EPCRA Section 313 report
(Form R), but that are required to evaluate the risks
associated with the release properly.
This additional information should be reported
on a special CR-ERNS format for TRI reporters called
Suggested CR-ERNS Reporting Format —
Addendum to TRI Form R. This special format
appears as Appendix C to this Guide. The format
includes all elements of information needed to
complement the TRI Form R information in order to
comply with the Continuous Release Rule. Appendix
E is an example of a properly Completed CR-ERNS
Reporting Format — Addendum to TRI Form R.
1.7 Where to Submit Written Reports
Your continuous release report and any written
follow-up reports or changes should be submitted to
your EPA Regional Office. Exhibit 1-7 provides the
addresses of each Regional office and shows the
location of all of the EPA Regions.

PART 2: INSTRUCTIONS AND PROCEDURES FOR
CONTINUOUS RELEASE REPORTING
2.0 Introduction
2.1 General Overview of How to
Report a Continuous Release
This part of the Guide includes detailed
instructions and procedures for complying with the
reporting requirements for continuous releases. These
instructions are intended to assist you in supplying the
information required by the implementing regulations
"Reporting Continuous Releases of Hazardous
Substances Final Rule" (40 CFR Parts 302.8 and
355.40). The instructions below cover both the
standard reporting requirements and the reporting
requirements for special circumstances. The standard
reporting requirements include the initial telephone
notification, the initial written report, and the one-time
first anniversary follow-up report. Reporting
requirements for special circumstances include reports
of SSIs, as well as reports of any changes in the release
that make the information submitted in the initial
written or follow-up reports inaccurate or out-of-date.
Part 2 of the Guide is organized into six sections.
Section 2.1 provides a general overview of how to
report continuous releases. Sections 2.2 through 2.5
explain each type of required notification. Within each
of these sections are detailed instructions on when and
where to submit each required report, as well as
instructions on what information to include in the
report. Section 2.6 provides a summary of the
information that must be provided by reviewing the
key elements of the Suggested Continuous Release
Reporting Format included in Appendix B of this
Guide. You are strongly encouraged to use this
suggested reporting format when completing your
written initial and follow-up reports to ensure that you
include all of the information required by the Rule.
This part of the Guide also provides other
materials to assist you in completing your written
reports including Exhibit 2-1, the checklist of the
information required in the initial written and follow-
up reports, which appears on page 19. This checklist
is another method that can be used to verify that all
required information has been collected and submitted.
If you have established that your release is
continuous and stable in quantity and rate, you may
begin reporting under CERCLA Section 103(f)(2). As
discussed in Part 1 of this Guide, the continuous
release reporting regulation provides you with two
options for reporting continuous releases of CERCLA
hazardous substances. You may aggregate multiple
concurrent releases of the same hazardous substance
from contiguous or adjacent facilities and report them
in a single notification, or you may consider each
facility separately and submit reports on a per facility
basis. Although you may elect either option for
notification of continuous releases, whichever option
you elect must also be used for reporting statistically
significant increases (SSIs) in the release and reporting
changes in information previously submitted.
To report a continuous release from your facility,
you must comply with the standard reporting
requirements under the Rule which require you to
make an initial telephone notification, an initial
written report, and a one-time, first anniversary follow-
up report. In the written reports (i.e., the initial
written report and the follow-up report), you must
provide specific information that describes your
continuous release. This information includes
identifying the facility and providing certain ecological
and population-density information on the surrounding
area, as well as information on the source of the
release. You must identify all sources of continuous
release from your facility (e.g., smoke stacks, waste
piles, valves) whenever those facility-wide releases
equal or exceed an RQ. You must also provide
substance-specific information on each hazardous
substance released from each identified source (40
CFR 302.8(e)).
In addition to the standard reporting
requirements of the initial telephone notification and
the written reports, under certain circumstances you
must make additional reports. You must report any
16
-------
SSIs in the release, as well as any changes in the
release that make the information submitted in the
initial written or follow-up reports inaccurate or out-of-
date. The specific information required in each of
these types of continuous release reports is outlined in
the sections below. The instructions for reporting
continuous releases contained in this part of the Guide
are written for those who elect to report each facility
separately and therefore they refer to "facilities" rather
than "sites." The instructions for reporting releases
from sites are the same as those described for facilities
below.
2.2 Initial Telephone Notification
When should you notify?
The continuous release reporting regulation
requires that an initial telephone notification be made
as soon as you have a sufficient basis for establishing
that the release is continuous and stable in quantity
and rate. You may rely on release data, engineering
estimates, knowledge of the plant's operations and
release history, professional judgment, or any other
method that has a strong technical basis to establish
the basis for asserting that the release is continuous
and stable in quantity or rate, or you may report the
release (to the NRC for CERCLA hazardous
substances or to the SERC and LEPC for non-
CERCLA EHSs) for a period sufficient to establish the
continuity and stability of the release; (for further
information on how to establish a release as continuous
and stable in quantity and rate, refer to pages 3 and 4
of this Guide).
If a sufficient basis for establishing the release as
continuous exists for a CERCLA hazardous substance,
a minimum of one telephone call may be made to the
NRC, SERC, and LEPC. For non-CERCLA EHSs,
only the appropriate SERC and LEPC need be notified.
In either case, you may report all continuous releases
of hazardous substances at your facility in one
telephone report to each authority.
Who must be notified?
If you are the person in charge, owner or
operator, of the facility from which a continuous
release of a hazardous substance occurs, you must
telephone the following organizations:
• For CERCLA hazardous substances:
National Response Center (NRC)
Toll-free telephone number:
1-800-424-8802;
Washington, DC area: 1-202-267-2675;
• For CERCLA hazardous substances and non-
CERCLA EHSs:
The State Emergency Response
Commission (SERC) of any state likely to
be affected by the release; and
The Local Emergency Planning Committee
(LEPC) of any area likely to be affected
by the release.
Required information
The person in charge (for CERCLA hazardous
substances) or the owner or operator (for non-
CERCLA EHSs) is required to provide the information
listed below to government authorities in the initial
telephone notification.
1. Identify your report as a report of a continuous
release under CERCLA Section 103(f)(2). It is
very important for tracking purposes that the
person at the NRC, SERC, and LEPC to whom
you speak understands that you are giving the
initial telephone notification of a continuous
release (rather than an episodic report).
2. Identify the name and location of the facility
responsible for the release and provide the
corporate affiliation and address.
3. Identify each hazardous substance released.
4. Provide your name and telephone number and, if
different, the name and telephone number of the
person in charge of the facility.
If you are reporting a release of a CERCLA
hazardous substance, when you make this initial
telephone call to the NRC, you will be assigned a CR-
ERNS number. This CR-ERNS number will become
the identifier for your facility. Your CR-ERNS
number will never change; it is the number that
identifies you in the CR-ERNS database.
17
-------
If you are reporting a non-CERCLA EHS to the
appropriate SERC or LEPC you will not receive a CR-
ERNS number as your SERC and LEPC will use their
own methods to track your continuous release.
2.3 Initial Written and Follow-Up
Reports
Where and when to submit initial written and
follow-up reports?
Within 30 days of your initial telephone call to
the NRC, SERC, and LEPC, the initial written report
of CERCLA hazardous substances must be submitted
to the appropriate government authorities. You must
send one copy of the completed initial written report
containing the information described in this Section to
each of the following organizations:
The EPA Regional Office for the
geographical region in which your facility
is located;
The SERC of any state likely to be affected
by the release; and
The LEPC of any area likely to be affected
by the release.
For reports of CERCLA hazardous substances,
the one-time, first anniversary follow-up report must
be submitted within 30 days of the first anniversary
date of the initial written report to the EPA Regional
Office. The first anniversary follow-up report must be
submitted to the EPA Regional Office only. You are
not required to submit the one-time first anniversary
follow-up report to the SERC and LEPC.
Reports of releases of non-CERCLA EHSs must
be reported only to the SERC and LEPC. No
notification of Federal authorities is required.
What information is required?
The information that you are required to submit
for all initial written and follow-up reports can be
divided into three primary sections: general
information: source information: and hazardous
substance information. These sections are described
briefly below and the specific information to be
included in each of these sections is described more
fully in the following pages.
• Section I - General Information. This section
includes identifying information about your
facility, as well as information concerning the
area surrounding your facility.
• Section II - Source Information. This section
includes information on each source of the
release including: the identity of each source; the
basis for stating that the release from a source
qualifies as continuous and stable in quantity and
rate; the environmental medium affected by the
release; the names and quantities of the
CERCLA hazardous substances or EHSs released
from the source; and the normal range and
frequency of the release. This information must
be provided separately for each source of the
continuous release.
• Section III - Hazardous Substance Information.
This section includes the upper bound of the
normal range for each hazardous substance
released across all sources at a facility. This
number is also known as the SSI trigger. Section
II should be completed for each release source
before you calculate the upper bound of the
normal range of the release for each CERCLA
hazardous substance or EHSs across all sources
at the facility.
Section I: General Information
The information required in Section I of the
initial written report and follow-up reports includes
general information identifying your facility, as well as
information regarding the area in which your facility
is located. This general information is important
because it provides a better understanding of the
potential risks resulting from exposure from the
facility's release. A signed statement asserting that the
continuous release is continuous and stable in quantity
and rate, and that the information supplied is accurate
and current to the best of your knowledge, is also
required in Section I.

CHECKLIST OF INFORMATION REQUIRED IN INITIAL AND FOLLOW-UP WRITTEN REPORTS
19
-------
In addition to the information required on the
following pages, Section I must clearly identify the
type of written report that you are submitting (i.e., an
initial written report, a first anniversary follow-up
report, or a written report of the change in source or
composition of a previously reported release). You
must also include information on the initial
notification of the release, such as the date of the
release and the date of the initial call. For CERCLA
hazardous substances, the CR-ERNS number assigned
to you by the NRC will also be required.
Section I: General Information
Part A: Facility Information
In Part A, provide the following information:
1. The complete name of your facility (and
company identifier where appropriate). If
multiple facilities are included in your written
report, provide the plant site name with the name
of the facility.
2. The full address of your facility, including the
street address or highway marker, city, county,
state, and zip code. A post office box number
should not be used as the facility address. The
address provided should be the location of the
facility where the hazardous substance release
occurs.
3. The location of your facility by its latitude and
longitude in units of degrees, minutes, and
seconds. Exhibit 2-2 includes helpful hints on
how to obtain the latitude and longitude
coordinates of your facility.
4. The nine digit number assigned by Dun and
Bradstreet (D&B) to your facility. This number
can be obtained via telephone by an officer of
your company from the national office of Dun
and Bradstreet (at 1-800-234-3867). If your
facility has not been assigned a D&B number,
please specify that the information is not
applicable.
5. For reports of CERCLA hazardous substances,
the CR-ERNS number assigned by the NRC
when you made the initial telephone report. Be
certain to include the CR-ERNS number on each
page of your report.
6. The name, telephone number (including area
code), and an alternate telephone number for the
person in charge of your facility.
EXHIBIT 2-2
SOURCES OF INFORMATION FOR
IDENTIFYING THE LOCATION OF YOUR
FACILITY
Sources of data on latitude and longitude
coordinates of your facility include EPA
permits (e.g., NPDES permits), county
property records, facility blueprints, and site
plans.
In addition, information on the latitude and
longitude of your facility may be obtained
from a United States Geological Survey
(USGS) topographical map. These maps are
available in both the 7.5 minute and 15
minute series. These maps may be obtained
from the USGS distribution center at your
local public library. If you would like to
order a map from USGS, contact:
U.S. Geological Survey
Branch of Distribution
Box 25286 Federal Center
Denver, CO 80225
If you are not certain on which map your site
is located, consult the index of topographic
maps for your state, which may be obtained
from USGS free of charge. USGS maps are
also available at commercial dealers such as
surveyors or outdoor recreation equipment
dealers.

Section I: General Information
Part B. Population Information
Section II: Source Information
In Part B, provide the following information:
1. Choose the range listed below that most
accurately describes the population density
within a one-mile radius of your facility:
0-50 person(s)
51-100 persons
101-500 persons
501-1000 persons
more than 1000 persons.
2. Identify and describe the location of any sensitive
populations or ecosystems (see Exhibit 2-3 for
definitions and examples) within a one-mile
radius of your facility. If possible, describe the
location of the populations or ecosystems in
terms of distance and direction from your facility
(e.g., located 'A mile northwest of the facility).
Exact addresses are not required.
EXHIBIT 2-3
DEFINITIONS
Sensitive populations are populations likely to
be more susceptible than average individuals to
the effects of exposure to a hazardous substance.
Examples of sensitive populations are elementary
school children, retirement communities, or
hospitals.
Sensitive ecosystems are environments likely to
be more susceptible than average environments to
the effects of exposure to a hazardous substance,
or ecosystems that have been designated for
special protection by Federal or state
governments. Examples of sensitive ecosystems
include wetlands, wildlife refuges, tidal basins,
or endangered species habitats.
General overview
When completing your written reports, you must
take into consideration all sources of the release from
your facility. For example, if the aggregate amount of
a particular hazardous substance released within 24
hours from your facility equals or exceeds an RQ, then
each source of the particular release must be identified,
even if some release amounts from individual sources
do not equal or exceed the RQ. The purpose of
requiring information on the source(s) of the release is
to provide EPA with sufficient information to evaluate
the risk associated with the continuous release.
Providing this information accurately in the initial
written and first anniversary follow-up report will
minimize future requests by EPA for additional
information or clarification.
In this section of the written report, you should
identify and describe separately each continuous
release source. If the continuous release of the same
hazardous substance comes from two or more sources
(e.g., two stacks), then information should be reported
separately for each of the sources. For example, if a
stack is one of several sources of a hazardous substance
release at your facility, you must provide information
on that stack including: the stack height; the identity
of the hazardous substance(s) being released from the
stack; the quantity released; and the frequency of the
release from the stack. If you have a release of a
particular hazardous substance from three stacks, you
should report each stack separately and provide the
required information specified for each stack.
Although the continuous release reporting
regulation allows multiple concurrent releases of the
same CERCLA hazardous substance to be considered
as if they were one continuous release, aggregate
reporting of such releases from different sources
complicates risk analyses. Area sources are most
readily aggregated for purposes of continuous release
reporting and risk evaluation when the frequency of
the release from each source is the same. Similarly,
aggregated stack releases are most readily evaluated if
the frequency of the release from each stack is the
same and the stack configurations (e.g., stack height,
diameter, throughput) are the same. If you elect to
aggregate releases across facilities, be certain to
identify information about each source of the release
21
-------
from all of your facilities. Also, note that if you
aggregate your releases, EPA may request clarifying
information about the releases from each of the
individual sources.
Identification of sources
In Section II, you must identify (i.e., name) and
describe each continuous release source. There are
several ways to name release sources. It is important
to: (1) provide a name that clearly identifies the source
(e.g., centrifugal processor A, rather than Unit A); and
(2) avoid giving two or more sources the same name.
It is also important to remember when naming your
sources that EPA, at any time, may contact you with
questions regarding releases from one of your named
sources. It would be prudent, therefore, to name the
sources at your facility in a manner that will be easy
for you and other employees to identify them. For
example, if your plant has four stacks, two wastepiles,
and twenty-four valves, you may name the sources as
follows: Stack #1; Stack #2; Stack #3; Stack #4;
Wastepile #1; Wastepile #2; and Valves in Building
#2. Note that the "Valves in Building #2" are
aggregated in this example and reported as a single
source.
Required information
Section II, Source Information, contains three
Parts: Part A, Part B, and Part C. You must provide
the information required in each of these Parts for each
continuous release source. Be sure to place the name
of the source on all pages associated with that specific
source. A summary of the type of information required
in each Part is provided below.
Part A - Requests information on the basis for
asserting that the release from each identified
source is continuous and stable in quantity and
rate.
Part B - Requires specific information on the
environmental medium affected by the hazardous
substance release from each identified source.
Part C - Requires information on the hazardous
substance(s) and mixture(s) released from the
identified source, such as the upper bound of the
normal range of the hazardous substance.
The information required in Parts A, B, and C is
described more fully below and is used to assist EPA
and other government authorities in evaluating the
risks associated with the continuous release. It is
important to remember when completing your format
to include for each source all of the information
required in each part of Section II.
There is one exception to this rule. If the release
from any individual source will affect more than one
environmental medium (e.g., a wastepile releasing to
air and ground water) it must be modeled separately.
Therefore, any source that affects two different media
should be treated as two separate sources for purposes
of reporting. This is desirable because EPA must
analyze each release pathway separately to properly
evaluate the risks posed by the continuous release. In
addition, because the hazardous substance releases to
each medium may differ in frequency and quantity, it
is useful to distinguish the releases for purposes of risk
evaluation.
Section II: Source Information
Part A: Basis for Asserting the Release is
Continuous and Stable in Quantity and
Rate
In Part A of Section II, you must first identify the
source of the release (include the name of the source in
all subsequent parts), then briefly describe the basis for
stating that the release is continuous and stable in
quantity and rate. Your description of the basis for
stating that the hazardous substance release is
continuous and stable in quantity and rate should
include whether the release is continuous without
interruption, or is a routine, anticipated, intermittent
release. It should also include information on when
the release is expected to occur (i.e., evidence of
predictability of the release). One example of a release
that may be predictable and regular is fugitive
emissions from valves that occur at different rates over
the course of a production cycle as the pressure inside
the system changes. Although the rate of such fugitive
emissions may not be strictly uniform, it may be
predictable in the sense that the rate and amount of the
release vary in a similar manner each time the process
is operated or decompression occurs.
Your description should also identify the activity
that results in the release (e.g., batch process,
operating procedure, loading/unloading, maintenance
activity, filling of storage tanks). If the release occurs
because of a malfunction, this should be explained
22
-------
fully. Note that only certain releases due to
malfunctions can qualify as a continuous release.
Please refer to the discussion in the preamble of the
continuous release Final Rule at 55 FR 30171 or the
discussion on page 4 of this Guide to determine
whether a malfunction can qualify as a continuous
release.
Finally, your description should include
information on how you established the pattern of the
release and calculated release estimates (e.g.,
engineering estimates, your best professional
judgment, past release data).
In sum, when identifying your sources, refer to
the directions above on how to name sources. For each
source identified, provide the following information.
1. Indicate whether the release is continuous
without interruption or abatement or routine,
anticipated, and intermittent.
2. Identify the activity or activities that cause the
release from the source.
3. If the release results from a malfunction, describe
the malfunction and explain why the release
should be considered continuous and stable in
quantity and rate.
4. Identify how you established the pattern of the
release and calculated release estimates.
Section II: Source Information
Part B. Specific Information on the Source
In Part B of Section II of your written report, you
must identify the environmental medium (i.e., air,
surface water, soil, or ground water) affected by the
hazardous substance release from each source
identified in Section II, Part A. In addition, you must
provide specific information on the source and its
affected environment. It is important to remember that
if you have a release from a single source that affects
two different media (e.g., gypsum stack releasing
radon to air and radionuclides to ground water), you
should treat the release to each medium as separate
source for purposes of reporting. Another important
point to remember when completing all sections of the
written report is to include the appropriate units, such
as kilograms, meters, or curies.
For each source identified in Part B, provide the
following information.
Environmental medium
Identify the environmental medium (i.e., air,
surface water, soil, or ground water) that is affected by
the release from the identified source.
1. Air
If the medium affected is air, provide the
following information:
(a) Indicate whether the source is a stack or
ground-based area source.
(b) If the source is a stack, provide the stack
height in feet or meters. The stack height
is the distance from the ground to the top of
the stack.
(c) If the source is an area source (e.g., a waste
pile, surface impoundment, landfill, valve,
pump seal, or storage tank vent), provide
an estimate of the surface area or area of
the release source including the appropriate
unit such as square feet, square meters, or
acres.
2. Surface Water
If the medium affected is surface water, provide
the following information:
(a) If the release affects any surface water
body, give the name of the water body.
(b) If the release affects a stream, give the
"stream order" or the average flow rate (in
cubic feet per second). This information
can be obtained from your state water
resource division of USGS. If you cannot
locate this information, use the chart in
Exhibit 2-4 to estimate the flow rate
according to the velocity of the stream. If
the velocity of the stream fluctuates during
the year, use the average velocity when
calculating average flow rate.

Optional information
The following information is not required in the
Continuous Release Rule; however, such information
will assist EPA in evaluating the risks associated with
a continuous release. If the information below is not
provided, conservative values will be used to evaluate
the risks associated with the continuous release.
1. If the source is a stack release to air, provide
the: (a) inside diameter of the stack; (b) gas exit
velocity; and (c) gas temperature.
2. If the release affects surface water, provide
the average velocity of the surface water.
(c) If the release affects a lake, or other large surface
water body (e.g., a bay) give the surface area of
the lake (in acres) and the average depth (in feet
or meters). Exhibit 2-5 includes sources of
information on how to determine the average
depth of a lake.
EXHIBIT 2-5
SOURCES OF INFORMATION FOR
ESTIMATING AVERAGE LAKE DEPTH
If the lake is large enough to be navigable, your
local Coast Guard office will have a navigation
chart that will provide the average depth of the
lake. For smaller lakes, you may estimate the
average depth of the lake by relying on your
knowledge of the use of the lake and the
surrounding area, and your best professional
judgment.
3. Soil or Ground Water
If the medium affected is soil or ground water,
provide the following information:
(a) If the release is on or under ground,
indicate the distance to the closest water
well within a two-mile radius of the site.
Section II: Source Information
Part C. Identity and Quantity of Each
Hazardous Substance or Mixture
Released
For each source, you must report information
about the identity and quantity of the hazardous
substances released from the source. In particular, you
must identify the normal range of each release and the
total annual quantity released during the previous year
from each source. The regulatory definition of the
"normal range" of a continuous release is provided in
Exhibit 2-6.
EXHIBIT 2-6
NORMAL RANGE
The normal range of a continuous release
includes all releases of a hazardous substance (in
pounds or kilograms) reported or occurring
during any 24-hour period under normal
operating conditions during the previous year.
Only releases that are both continuous and stable
in quantity and rate may be included in the
normal range.
24
-------
EXHIBIT 2-7: EXAMPLES OF REPORTING SINGLE HAZARDOUS SUBSTANCES
In this example, your facility has a release which may qualify for reduced reporting as a continuous release.
The hazardous substances released from the identified source (Stack A) are nitrogen dioxide (10102440) and
nitric oxide (10102439).
The volume of nitrogen dioxide (N02) released in a 24-hour period is between 0 and 120 lbs. During the
previous year, 960 lbs of N02 was released. The release occurs once per week in February and June for a
total of 8 days per year. The amount of nitric oxide (NO) released is between 1 and 115 lbs. The release of
NO occurs approximately 120 days each year. A total amount released last year was 13,800 lbs.
For these releases from the specific source, you must provide the information outlined below.

You are not necessarily required to monitor
releases to determine the normal range of the release.
You may establish the normal range by using
engineering estimates of releases under various
operating conditions, knowledge of the operating
history of the facility, experience with operating
processes, professional judgment, or any other method
that has a sound technical basis. EPA will use the
upper bound of the normal range to estimate the risks
to human health and the environment posed by the
hazardous substance release.
To provide the required information regarding
the quantity of the hazardous substance released from
each identified source, you should begin by
determining whether the release is a single hazardous
substance or a mixture of hazardous substances. If the
release is of one or more single hazardous substances,
follow the directions provided below in Example A.
If the release is a mixture of hazardous substances, you
have two options. For a mixture you may complete
Part C either: 1) by reporing each hazardous substance
as if it were a discrete and separate release (as in
Example A); or 2) by reporting the release as a
mixture and identifying the hazardous substance
components of the mixture along with information on
the weighted contribution of each component in the
mixture (as in Example B).
Example A: Single hazardous substances
For each source, follow the directions below to
report each hazardous substance released from the
source that is a single hazardous substance or a
component of a mixture that you wish to report
separately. Exhibit 2-7 provides an example of how to
report releases of single hazardous substances.
1. Identify the hazardous substance released by
name and by Chemical Abstracts Service
Registry Number (CASRN). The CASRN for a
hazardous substance can be located in any
material safety data sheet or in most chemical
supplier company catalogues.
2. Provide the upper and lower bounds of the
normal range of the release from the identified
source (i.e., quantity in pounds, kilograms, or
curies) during the previous year.
3. Estimate the total annual amount (in pounds,
kilograms, or curies) of the hazardous substance
25
-------
released from the identified source during the
previous year.
TABLE 2-8: EXAMPLE OF REPORTING A MIXTURE
In this example, if your facility wants to report the release of a mixture of hazardous substances, you must list
each component of the mixture by hazardous substance and include its percentage by weight. For example,
for the release of mixture Z, you must provide the following information about its components, ethylene
oxide, acrolein, and 2,3,5-tri-chlorophenol:
Name of
Normal Range of Normal Range of Number of Total Quantity
Hazardous
Components Mixture Days Release of Mixture

4. Specify the frequency of the release by indicating
the number of days the release occurs per year
from the identified source. Stating "continuous"
is not sufficient, as one source may be
continuously operating 365 days a year, while
another source may be continuously operating on
weekdays, 261 days a year.
5. Indicate the actual months the release occurs.
Example B: Mixture
For each source, follow the directions below to report
each mixture released from the source. Exhibit 2-8
provides an example on how to report a mixture.
1. Identify the mixture by name (e.g., Blue Pigment
#25).
2. Identify each hazardous substance component of
the mixture by name and CASRN.
3. Estimate the percentage by weight of each
hazardous substance component of the mixture.
4. Provide the upper and lower bounds (i.e.,
quantity in pounds, kilograms, or curies) of the
normal range of each hazardous substance
component of the mixture that was released from
this source. To calculate the upper bound of the
normal range of each hazardous substance
component, multiply the weight percentage of
each component by the upper bound quantity of
the mixture.
5. Provide the upper and lower bounds (i.e.,
quantity in pounds, kilograms, or curies) of the
normal range of the mixture that was released
from the identified source during the previous
year.
6. Specify the frequency of the release by indicating
the number of days the release occurs per year
from the identified source. Stating "continuous"
is not sufficient, as one source may be
continuously operating 365 days a year, while
another source may be continuously operating on
weekdays, 261 days a year.
7. Estimate the total annual quantity (in pounds,
kilograms, or curies) of the mixture that was
released from the identified source during the
previous year.
8. Indicate the actual months the release occurs.
26
-------
Section III: Hazardous Substance Information
After you provide the required information for all
sources of continuous releases from your facility, you
must aggregate information of a hazardous substance
release from aft sources to determine the SSI trigger
(upper bound of the normal range) for each hazardous
substance released at your facility.
The SSI trigger of a particular hazardous
substance is calculated by aggregating the upper
bounds of the hazardous substance released across all
sources at a facility.
If you are aggregating CERCLA hazardous
substance releases from separate, contiguous, or
adjacent facilities and reporting them in a single
report, aggregate the upper bound of the normal range
of the hazardous substance released from all sources at
the site to determine the SSI trigger. If you aggregate
your releases across facilities, the SSI trigger must also
be site-specific, not facility-specific. Aggregating
releases across facilities at the same site may reduce
your reporting burden; however, EPA will evaluate the
risks associated with the releases as if the releases were
from one facility.
To calculate the SSI trigger for each hazardous
substance you should:
1. List each specific source name and enter the
upper bound of the normal range of the release
from that source. If the identified hazardous
substance is a component of a mixture, enter the
upper bound of the normal range for that
component of the mixture (as determined in
Section II, Part C).
2. Aggregate the upper bound quantities from each
source of the release. Report these totals as the
SSI trigger for the hazardous substance. The
example that is provided in Exhibit 2-9
illustrates the calculation of the SSI trigger for a
release of ammonia.
The above method for calculating the SSI trigger
of a hazardous substance assumes that all releases of

facility are the Tank Vents in Building #1 and the
Valves in Building #5.
the same hazardous substance occur simultaneously
(i.e., over the same 24-hour period). To the extent that
the frequency of the release differs, you may adjust the
SSI trigger so that it more accurately reflects the
frequency and quantity of the hazardous substance
released from all sources over a 24-hour period. The
SSI trigger in the final analysis must reflect the upper
bound of the normal range of the release, taking into
consideration all sources of the release at the facility.
The normal range of the release includes all
continuous releases previously reported or occurring
over a 24-hour period during the previous year.
Signed statement
After providing the information required in
Sections I through III, as described above, the person
in charge of the facility must sign a statement asserting
that the information provided is accurate and current
to the best of his or her knowledge. This statement
must be similar to the following:
"I certify that the hazardous substance releases
described herein are continuous and stable in quantity
and rate under the definitions in 40 CFR 302.8(a) or
355.4(a)(2)(iii) and that all submitted information is
accurate and current to the best of my knowledge."
In addition, the person in charge of the facility
must print clearly his/her name and position and date
the certification statement.
27
-------
2.4 Notifications of Statistically
Significant Increases
When do you submit SSI reports?
An SSI is an episodic release that must be
reported whenever the hazardous substance release
exceeds the continuous release SSI trigger (i.e., the
upper bound of the normal range of the release) within
a 24-hour period. The determination of whether a
release is an SSI should be based upon calculations or
estimation procedures that identify the release as
exceeding the upper bound of the reported normal
range of the continuous release. The person in charge
of a facility must report an SSI of a CERCLA
hazardous substance to the NRC, SERC, and LEPC,
and the owner or operator of a facility must report an
SSI of a non-CERCLA EHS to the SERC and LEPC,
as soon as the facility is aware that the release has
occurred.
Who must be notified?
If you are the person in charge, or owner or
operator, of the facility from which an SSI in a
continuous release occurs, you must telephone the
following government organizations:
• For CERCLA hazardous substances:
NRC
Toll-free telephone number:
1-800-424-8802;
Washington, DC area: 1-202-267-2675;
• For CERCLA hazardous substances and non-
CERCLA EHSs:
The SERC of any state likely to
be affected by the release; and
The LEPC of any area likely to be affected
by the release.
In addition to these notifications, under the
requirements of SARA Title III Section 304, you must
submit a written follow-up notice to the SERC and
LEPC. For information on the addresses and
telephone
numbers of SERCs and LEPCs, contact the
RCRA/Superfund/EPCRA Hotline toll free at
1-800-424-9346. (See Exhibit 1-7 on page 14)
What type of information is required in SSI
reports?
In the telephone notification, the release should
be identified as an SSL For reports of releases of
CERCLA hazardous substances, the person in charge
of the facility should also provide the original CR-
ERNS number assigned by the NRC. This will ensure
that the SSI report is recorded correctly and evaluated
properly.
The person in charge will be asked to provide all
of the information required in an episodic release
report under CERCLA Section 103(a). An SSI is a
type of episodic release. It represents a release of a
hazardous substance above an RQ that has never been
evaluated or considered.
What are that requirements for modifying the SSI
trigger?
In the event that a particular continuous release
at a facility frequently exceeds the upper bound of the
normal range, the person in charge may want to
modify the previously established upper bound(s) of
the relevant hazardous substances as an alternative to
reporting successive SSIs.
To modify the SSI trigger, you must report at
least one release as an SSI (to facilitate immediate
evaluation). During such a report, you may also notify
the government authorities of the new upper bound of
the release. For reports of CERCLA hazardous
substances, within 30 days of the telephone
notification, you must submit a written notification to
the EPA Regional Office in your geographical area,
describing the new normal range, the reason for the
change, and the basis for certifying that the release is
continuous and stable at the higher amount. A
modification of the SSI trigger is a type of change in
source or composition and therefore is reported as a
new release under the "old" CR-ERNS number.
Although it is not required, it is also advised that you
notify the appropriate SERC and LEPC.
28
-------
2.5 Reports of Changed Releases
Where and when do you submit reports of changed
releases?
The person in charge of the facility must notify
the appropriate government authorities if there are any
of the following changes in a continuous release.
Change in Source or Composition
If there is a change in the source(s) or
composition of a continuous release, the release is
considered a "new" release. A change in the source(s)
or composition of a release may be caused by factors
such as equipment modifications or process changes.
The new release may pose a hazard that warrants
timely evaluation and, therefore, to report this new
release under CERCLA Section 103(f)(2), you must
establish the new release as continuous and stable in
quantity and rate (i.e., for CERCLA hazardous
substances, call the NRC, SERC, and LEPC; for non-
CERCLA EHSs, call the SERC or LEPC; and in both
cases, submit a new initial written report and follow-up
report).
For CERCLA hazardous substances, when you
make the initial telephone call to the NRC, provide
your original CR-ERNS number. When submitting
your new written initial report to the EPA Regional
Office, SERC, and LEPC (for a report of a release of a
CERCLA hazardous substance), or only the SERC and
LEPC (for a report of a release of a non-CERCLA
EHS), be certain to specify whether you are adding a
new source(s), deleting a source(s), or modifying the
list of hazardous substances previously reported. In
addition, if your change report includes information
that has already been submitted, please clearly
differentiate between the new or changed information
and the previously reported information by either
placing a check mark in the left hand margin,
highlighting the information, or using any other means
to identify the changed or new information. It is
important to clearly identify new or changed
information.
Please note that each time you submit a written
report of a change in the source or composition of a
release, you must recalculate the upper bound of the
normal range for each affected hazardous substance.
For example, if you add a source from which two
single hazardous substances (i.e., HS #1 and HS #2)
are released and you have previously reported releases
of these same substances from other sources, you must
recalculate, in Section III of the reporting format, the
upper bound of the normal range for both HS #1 and
HS #2. To obtain the new upper bound for HS #1, you
must add the upper bound of HS #1 released from the
new source to the upper bound of HS #1 released from
all other sources at your facility. The new upper bound
for HS #2 should be calculated in a similar manner.
Other Changes
If there is a change in the information submitted
in the initial written or follow-up reports of a release of
a CERCLA hazardous substance (other than a change
in the source or composition of the release) the person
in charge must notify the EPA Regional Office in
writing within 30 days of determining that the
information submitted previously is no longer valid.
One example of a change in the information submitted
previously, other than a change in the source or
composition of the release, is a change in ownership in
the facility.
All notifications of changes in releases of
CERCLA hazardous substances must include the CR-
ERNS number assigned by the NRC in your initial
telephone notification that identifies the facility. You
must also include a signed statement (see page 27 of
this Guide) certifying that the release is continuous and
stable in quantity and rate, and that all the reported
information on the release is accurate and current.
Although not required, it is advised that the
appropriate SERC and LEPC be notified of any
changes in other information regarding release of
either CERCLA hazardous substances or non-
CERCLA EHSs.

-------
General Overview of How to Report a Continuous Release
If you have established that your release is continuous and stable in quantity and rate, you may begin reporting under the Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA) Section 103(f)(2). The continuous release reporting regulation provides you with two options for reporting continuous releases of
CERCLA hazardous substances. You may aggregate multiple concurrent releases of the same hazardous substance from contiguous or adjacent facilities and report them in a
single notification, or you may consider each facility separately and submit reports on a per facility basis. Although you may elect either option for notification of continuous
releases, whichever options you elect must also be used for reporting statistically significant increases (SSIs) in the release and reporting changes in information previously
submitted.
To report a continuous release from your facility, you must comply with the standard reporting requirements under the Rule which require you to make an initial
telephone notification, an initial written report, and a one-time, first anniversary follow-up report. In the written reports (i.e., the initial written report and the follow-up report),
you must provide specific information that describes your continuous release. This information includes identifying the facility and providing certain ecological and population-
density information on the surrounding area, as well as information on the source of the release. You must identify all sources of continuous release from your facility (e.g.,
smoke stacks, waste piles, valves) whenever those facility-wide releases equal or exceed a reportable quantity (RQ). You must also provide substance-specific information on
each hazardous substance released from each identified source (40 CFR 302.8(e)).
In addition to the standard reporting requirements of the initial telephone notification and the written reports, under certain circumstances you must make additional
reports. You must report any SSIs in the release, as well as any changes in the release that make the information submitted in the initial written or follow-up reports inaccurate
or out-of-date. The specific information required in each of these types of continuous release reports is outlined below.
Initial Telephone Notification
When should you notify? The continuous release reporting regulation requires that an initial telephone notification be made as soon as you have a sufficient basis for
establishing that the release is continuous and stable in quantity and rate. You may rely on release data, engineering estimates, knowledge of the plant's operations and release
history, professional judgment, or any other method that has a strong technical basis to establish the basis for asserting that the release is continuous and stable in quantity or
rate, or you may report the release (to the National Response Center (NRC) for CERCLA hazardous substances or to the State Emergency Response Commission (SERC) and
Local Emergency Planning Committee (LEPC) for non-CERCLA Extremely Hazardous Substances (EHSs)) for a period sufficient to establish the continuity and stability of the
release.
If a sufficient basis for establishing the release as continuous exists for a CERCLA hazardous substance, a minimum of one telephone call may be made to the NRC,
SERC, and LEPC. For non-CERCLA EHSs, only the appropriate SERC and LEPC need be notified. In either case, you may report all continuous releases of hazardous
substances at your facility in one telephone report to each authority.
Who must be notified? If you are the person in charge, owner or operator, of the facility from which a continuous release of a hazardous substance occurs, you must
telephone the following organizations:
1. For CERCLA hazardous substances - NRC (1-800-424-8802)
2. For CERCLA hazardous substances and non-CERCLA EHSs -
o The SERC of any state likely to be affected by the release; and
o The LEPC of any area likely to be affected by the release.
Required in formation. The person in charge (for CERCLA hazardous substances) or the owner or operator (for non-CERCLA EHSs) is required to provide the
information listed below to government authorities in the initial telephone notification.
1. Identify your report as a report of a continuous release under CERCLA Section 103(f)(2). It is very important for tracking purposes that the person at the NRC,
SERC,and LEPC to whom you speak understands that you are giving the initial telephone notification of a continuous release (rather than an episodic report).
2. Identify the name and location of the facility responsible for the release and provide the corporate affiliation and address.
3. Identify each hazardous substance released.
4. Provide your name and telephone number and, if different, the name and telephone number of the person in charge of the facility.
If you are reporting a release of a CERCLA hazardous substance, when you make this initial telephone call to the NRC, you will be assigned a CR-ERNS number.
This CR-ERNS number will become the identifier for your facility. Your CR-ERNS number will never change; it is the number that identifies you in the CR-ERNS database.
If you are reporting a non-CERCLA EHS to the appropriate SERC or LEPC you will not receive a CR-ERNS number as your SERC and LEPC will use their own
methods to track your continuous release.
Initial Written and Follow-up Reports
Where and when to submit initial written and follow-up reports? Within 30 days of your initial telephone call to the NRC, SERC, and LEPC, the initial written
report of CERCLA hazardous substances must be submitted to the appropriate government authorities. You must send one copy of the completed initial written report to each of
the following organizations:
• The EPA Regional Office for the geographical region in which your facility is located;
• The SERC of any state likely to be affected by the release; and
• The LEPC of any area likely to be affected by the release.
For reports of CERCLA hazardous substances, the one-time, first anniversary follow-up report must be submitted within 30 days of the first anniversary date of the initial
written report to the EPA Regional Office. The first anniversary follow-up report must be submitted to the EPA Regional Office only. You are not required to submit the one-time
first anniversary follow-up report to the SERC and LEPC.
Reports of releases of non-CERCLA EHSs must be reported only to the SERC and LEPC. No notification ofFederal authorities is required.
What information is required? The information that you are required to submit for all initial written and follow-up reports can be divided into three primary
sections: general information; source information; and hazardous substance information.
• Section I - General Information - This section includes identifying information about your facility, as well as information concerning the area surrounding
your facility.
• Section II - Source Information - This section includes information on each source of the release including: the identity of each source; the basis for stating
the release from a source qualifies as continuous and stable in quantity and rate; the environmental medium affected by the release; the names and quantities of
the CERCLA hazardous substances or EHSs released from the source; and the normal range and frequency of the release. This information must be provided
separately for each source of the continuous release.
• Section III - Hazardous Substance Information - This section includes the upper bound of the normal range for each hazardous substance released across all
sources at a facility. This number is also known as the SSI trigger. Section II should be completed for each release source before you calculate the upper bound
of the normal range of the release for each CERCLA hazardous substance or EHSs across all sources at the facility.

INSTRUCTIONS
SECTION I: GENERAL INFORMATION
CR-ERNS Number:
If you are reporting a release of a CERCLA hazardous substance(s), you will be assigned a CR-ERNS number when you make this initial telephone call to the NRC
(1-800-424-8802). This CR-ERNS number will become the identifier for your facility. Your CR-ERNS number will never change; it is the number that identifies you in
the CR-ERNS database.
The information required in Section I of the initial written report and follow-up reports includes general information identifying your facility, as well as information
regarding the area in which your facility is located. This general information is important because it provides a better understanding of the potential risks resulting
from exposure from the facility's release. A signed statement asserting that the continuous release is continuous and stable in quantity and rate, and that the
information supplied is accurate and current to the best of your knowledge, is also required in Section I.
In addition, Section I must clearly identify the type of written report that you are submitting (i.e., an initial written report, a first anniversary follow-up report, or a
written report of the change in source or composition of a previously reported release). You must also include information on the initial notification of the release,
such as the date of the release and the date of the initial call. For CERCLA hazardous substances, the CR-ERNS number assigned to you by the NRC will also be
required.
Type of Report - Select from drop-down list.
Initial Written Notification - Within 30 days of the initial telephone notification,
you are required to submit an initial written report to the appropriate EPA
Regional Office, SERC, and LEPC (for releases of CERCLA hazardous
substances) and to only the appropriate SERC and LEPC (for releases of non-
CERCLA EHSs). The purpose of this report is to confirm your intent to report
your release as a continuous release under Section 103(f)(2), and to provide
government response officials with sufficient information about your release to
enable them to determine if the release qualifies as a continuous release.
First Anniversary Follow-up Report - For reports of releases of CERCLA
hazardous substances, within 30 days of the first anniversary of your initial written
report, you are required to reassess your initial continuous release report and
gather the information on all of the reported substances being released. After
doing this, you must submit a one-time written first anniversary follow-up report to
the appropriate EPA Regional Office. Please note that the first anniversary report
must be sent to the appropriate EPA Regional Office for all reports of CERCLA
hazardous substances, but is not required for reports of non-CERCLA EHSs.
Written Notification of a Change to Initial Notification and/or Written Notification of a Change to Follow-up Report -
[NOTE: For these reports, select the report type that reflects the notification or report for which you are reporting a change.]
= Notification of a change in source or composition, which is treated as if it were a new release (i.e., with a telephone call to the NRC, SERC, and LEPC, followed by
a written report and a first anniversary fiollow-up report);
= Notification of a change in the normal range, if there is a change in the release such that the quantity of the release exceeds the upper bound of the reported normal
range, the release must be reported as a statistcally significant increase:
= For CERCLA substances only, notification of any other reported information (e.g., a change in facility ownership) in a written letter to only the EPA Region.
Part A. Facility or Vessel Information-
1. The complete name of your facility (and company identifier where appropriate). If multiple facilities are included in your written report, provide the plant site
name with the name of the facility.
2. The full address of your facility, including the street address or highway marker, city, county, state, and zip code. A post office box number should not be used
as the facility address. The address provided should be the location of the facility where the hazardous substance release occurs.
3. The location of your facility by its latitude and longitude in units of degrees, minutes, and seconds. See below for helpful hints on how to obtain the latitude
and longitude coordinates of your facility.
4. The nine digit number assigned by Dun and Bradstreet (D&B) to your facility. This number can be obtained via telephone by an officer of your company
from the national office of Dun and Bradstreet (at 1-800-234-3867). If your facility has not been assigned a D&B number, please specify that the information
is not applicable uv -i1 i' ' 1 tf.«'
5. For reports of CLRCLA hazatdonb sub Mantes, i)ie LR-hkNS number assigned by the NRC when you made the initial telephone report. Be certain to include
the CR-ERNS number on each page of your report.
6. The name, telephone number (including area code), and an alternate telephone number for the person in charge of your facility.
SOURCES OF INFORMATION FOR IDENTIFYING THE LOCATION OF YOUR FACILITY
Sources of data on latitude and longitude coordinates of your facility include EPA permits (e.g., NPDES permits), county property records, facility blueprints, and site
plans. In addition, information on the latitude and longitude of your facility may be obtained from a United States Geological Survey (USGS) topographical map.
These maps are available in both the 7.5 minute and 15 minute series. These maps may be obtained from the USGS distribution center at your local public library. If
you would like to order a map from USGS contact J LS,Geological Survey - Information Services, Box 25286, Denver, CO 80225, call 1-888-ASK-USGS

Part B. Population Information -
1. Choose the range from the drop down list, the range that most accurately describes the population density within a one-mile radius of your facility.
2. Identify and describe the location of any sensitive populations or ecosystems within a one-mile radius of your facility. If possible, describe the location of the
populations or ecosystems in terms of distance and direction from your facility (e.g., located V4 mile northwest of the facility). Exact addresses are not
required.
Sensitive populations - populations likely to be more susceptible than average individuals to the effects of exposure to a hazardous substance. Examples of sensitive
populations are elementary school children, retirement communities, or hospitals.
Sensitive ecosystems - environments likely to be more susceptible than average environments to the effects of exposure to a hazardous substance, or ecosystems that
have been designated for special protection by Federal or state governments. Example of sensitive ecosystems includes wetlands.

(Part A)
CR-ERNS Number:
If you are reporting a release of a CERCLA hazardous substance (s), you will be assigned a CR-ERNS number when you make this
initial telephone call to the NRC (1-800-424-8802) . This CR-ERNS number will become the identifier for your facility. Your CR-
ERNS number will never change; it is the number that identifies you in the CR-ERNS database.

written and first anniversary follow-up report will minimize future requests by EPA for additional information or clarification.
In this section of the written report, you should identify and describe separately each continuous release source. If the continuous release of the same hazardous
substance comes from two or more sources (e.g., two stacks), then information should be reported separately for each of the sources. For example, if a stack is one of
several sources of a hazardous substance release at your facility, you must provide information on that stack including: the stack height; the identity of the hazardous
substance(s) being released from the stack; the quantity released; and the frequency of the release from the stack. If you have a release of a particular hazardous
substance from three stacks, you should report each stack separately and provide the required information specified for each stack.
Although the continuous release reporting regulation allows multiple concurrent releases of the same CERCLA hazardous substance to be considered as if they were
one continuous release, aggregate reporting of such releases from different sources complicates risk analyses. Area sources are most readily aggregated for purposes
of continuous release reporting and risk evaluation when the frequency of the release from each source is the same. Similarly, aggregated stack releases are most
readily evaluated if the frequency of the release from each stack is the same and the stack configurations (e.g., stack height, diameter, throughput) are the same. If you
elect to aggregate releases across facilities, be certain to identify information about each source of the release from all of your facilities. Also, note that if you
aggregate your releases, EPA may request clarifying information about the releases from each of the individual sources.
Identification of sources - In Section II, you must identify (i.e., name) and describe each continuous release source. There are several ways to name release sources.
It is important to: (1) provide a name that clearly identifies the source (e.g., centrifugal processor A, rather than Unit A); and (2) avoid giving two or more sources the
same name. It is also important to remember when naming your sources that EPA, at any time, may contact you with questions regarding releases from one of your
named sources. It would be prudent, therefore, to name the sources at your facility in a manner that will be easy for you and other employees to identify them. For
example, if your plant has four stacks, two wastepiles, and twenty-four valves, you may name the sources as follows: Stack #7; Stack #2; Stack #3; Stack #4; Wastepile
#7; Wastepile #2; and Valves in Building #2. Note that the " Valves in Building #2 " are aggregated in this example and reported as a single source.
Required information - Section II, Source Information, contains three Parts (A, B, and C). You must provide the information required in each of these Parts for each
continuous release source. Be sure to place the name of the source on all pages associated with that specific source. There is one exception to this rule. If the release
from any individual source will affect more than one environmental medium (e.g., a wastepile releasing to air and ground water) it must be modeled separately.
Therefore, any source that affects two different media should be treated as two separate sources for purposes of reporting. This is desirable because EPA must
analyze each release pathway separately to properly evaluate the risks posed by the continuous release. In addition, because the hazardous substance releases to each
medium may differ in frequency and quantity, it is useful to distinguish the releases for purposes of risk evaluation.
Part A - Basis for Asserting the Release is Continuous and Stable in Quantity and Rate:
You must first identify the source of the release (include the name of the source in all subsequent parts), then briefly describe the basis for stating that the release is
continuous and stable in quantity and rate. Your description of the basis for stating that the hazardous substance release is continuous and stable in quantity and rate
should include whether the release is continuous without interruption, or is a routine, anticipated, intermittent release. It should also include information on when the
release is expected to occur (i.e., evidence ofpredictability of the release). One example of a release that may be predictable and regular is fugitive emissions from
valves that occur at different rates over the course of a production cycle as the pressure inside the system changes. Although the rate of such fugitive emissions may
not be strictly uniform, it may be predictable in the sense that the rate and amount of the release vary in a similar manner each time the process is operated or
decompression occurs.
Your description should also identify the activity that results in the release (e.g., batch process, operating procedure, loading/unloading, maintenance activity, filling
of storage tanks). If the release occurs because of a malfunction, this should be explained fully. Note that only certain releases due to malfunctions can qualify as a
continuous release. Please refer to the discussion in the preamble of the continuous release final rule at 55 FR 30171, Jul. 24, 1990.
Finally, your description should include information on how you established the pattern of the release and calculated release estimates (e.g., engineering estimates,
your best professional judgment, past release data).
For each source identified, provide the following information:
(1) Indicate whether the release is continuous without interruption or abatement or routine, anticipated, and intermittent.
(2) Identify the activity or activities that cause the release from the source.
(3) If the release results from a malfunction, describe the malfunction and explain why the release should be considered
continuous and stable in quantity and rate.
(4) Identify how you established the pattern of the release and calculated release estimates.

SECTION II: SOURCE INFORMATION
(Part B)
CR-ERNS Number:
If you are reporting a release of a CERCLA hazardous substance (s), you will be assigned a CR-ERNS number when you make this
initial telephone call to the NRC (1-800-424-8802). This CR-ERNS number will become the identifier for your facility. Your CR-
ERNS number will never change; it is the number that identifies you in the CR-ERNS database.
Part B - Specific In formation on the Source:
You must identify the environmental medium (i.e., air, surface water, soil, or ground water) affected by the hazardous substance
release from each source identified in Section II, Part A. In addition, you must provide specific information on the source and its
affected environment. It is important to remember that if you have a release from a single source that affects two different media
(e.g., gypsum stack releasing radon to air and radionuclides to ground water), you should treat the release to each medium as a
separate source for purposes of reporting. Another important point to remember when completing all sections of the written report
is to include the appropriate units, such as kilograms, meters, or curies.
Environmental medium - Identify the environmental medium (i.e., air, surface water, soil, or ground water) that is affected by the
release from the identified source.
1. Air - If the medium affected is air, provide the following information:
a. Indicate whether the source is a stack or ground-based area source.
b. If the source is a stack, provide the stack height in feet or meters. The stack height is the distance from the ground
to the top of the stack.
c. If the source is an area source (e.g., a waste pile, surface impoundment, landfill, valve, pump seal, or storage tank
vent), provide an estimate of the surface area or area of the release source including the appropriate unit such as
square feet, square meters, or acres.
2. Surface Water - If the medium affected is surface water, provide the following information:
a. If the release affects any surface water body, give the name of the water body.
b. If the release affects a stream, give the "stream order" or the average flow rate (in cubic feet per second). This
information can be obtained from your state water resource division ofUSGS. If you cannot locate this
information, use the chart below to estimate the flow rate according to the velocity of the stream. If the velocity of
the stream fluctuates during the year, use the average velocity when calculating average flow rate.
c. If the release affects a lake, or other large surface water body (e.g., a bay) give the surface area of the lake (in
acres) and the average depth (in feet or meters). Below are sources of information for estimating the average lake
depth.
3. Soil or Ground Water - If the medium affected is soil or ground water, provide the following information:
a. If the release is on or under ground, indicate the distance to the closest public water supply well within a two-mile
radius of the site. Information regarding the location ofpublic water supply wells may be available through the
county office that issues permits for wells.

Sources of Information for Estimating Average Lake Depth
If the lake is large enough to be navigable, your local Coast
Guard office will have a navigation chart that will provide the
average depth of the lake. For smaller lakes, you may estimate
the average depth of the lake by relying on your knowledge of
the use of the lake and the surrounding area, and your best
professional judgment.
Optional in formation - The following information is not required to comply with the regulation; however, such information will assist EPA in evaluating the risks
associated with a continuous release. If the information below is not provided, conservative values will be used to evaluate the risks associated with the continuous
release.
1. If the source is a stack release to air, provide the: (a) inside diameter of the stack; (b) gas exit velocity; and (c) gas temperature.
2. If the release affects surface water, provide the average velocity of the surface water.

SECTION II: SOURCE INFORMATION
(Part C)
CR-ERNS Number:
If you are reporting a release of a CERCLA hazardous substance (s), you will be assigned a CR-ERNS number when you make this initial telephone call to the NRC
(1-800-424-8802). This CR-ERNS number will become the identifier for your facility. Your CR-ERNS number will never change; it is the number that identifies you in the CR-
ERNS database.
Part C - Identity and Quantity of Each Hazardous Substance or Mixture Released:
For each source, you must report information about the identity and quantity of the hazardous substances released from the source. In particular, you must identify the normal
range of each release and the total annual quantity released during the previous year from each source.
You are not necessarily required to monitor releases to determine the normal range of the release. You may establish the normal range by using engineering estimates of releases
under various operating conditions, knowledge of the operating history of the facility, experience with operating processes, professional judgment, or any other method that has a
sound technical basis. EPA will use the upper bound of the normal range to estimate the risks to human health and the environment posed by the hazardous substance release.
To provide the required information regarding the quantity of the hazardous substance released from each identified source, you should begin by determining whether the release
is a single hazardous substance or a mixture of hazardous substances.
Normal Range
The normal range of a continuous release includes all releases of a hazardous substance (in pounds, kilograms, or curies) reported or occurring during any 24-hour period under
normal operating conditions during the previous year. Only releases that are both continuous and stable in quantity and rate may be included in the normal range.
Reporting Single Hazardous Substances - For each source, follow the directions below to report each hazardous substance released from the source that is a single hazardous substance or a component of a mixture that you
wish to report separately.
1. Identify the hazardous substance released by name and by Chemical Abstracts Service Registry Number (CASRN). The CASRN for a hazardous substance can be located in any material safety data sheet or in
most chemical supplier company catalogues.
2. Provide the upper and lower bounds of the normal range of the release from the identified source (i.e., quantity in pounds, kilograms, or curies) during the previous year.
3. Estimate the total annual amount (in pounds, kilograms, or curies) of the hazardous substance released from the identified source during the previous year.
4. Specify the frequency of the release by indicating the number of days the release occurs per year from the identified source. Stating "continuous " is not sufficient, as one source may be continuously operating 365
days a year, while another source may be continuously operating on weekdays, 261 days a year.
5. Indicate the actual months the release occurs.
Reporting a Mixture - For each source, follow the directions below to report each mixture released from the source.
1. Identify the mixture by name (e.g., Blue Pigment #25).
2. Identify each hazardous substance component of the mixture by name and CASRN.
3. Estimate the percentage by weight of each hazardous substance component of the mixture.
4. Provide the upper and lower bounds (i.e., quantity in pounds, kilograms, or curies) of the normal range of each hazardous substance component of the mixture that was released from this source. To calculate the
upper bound of the normal range of each hazardous substance component, multiply the weight percentage of each component by the upper bound quantity of the mixture.
5. Provide the upper and lower bounds (i.e., quantity in pounds, kilograms, or curies) of the normal range of the mixture that was released from the identified source during the previous year.
6. Specify the frequency of the release by indicating the number of days the release occurs per year from the identified source. Stating "continuous " is not sufficient, as one source may be continuously operating 365
days a year, while another source may be continuously operating on weekdays, 261 days a year.
7. Estimate the total annual quantity (in pounds, kilograms, or curies) of the mixture that was released from the identified source during the previous year.
8. Indicate the actual months the release occurs.

Calculation of the SSI Trigger
For EACH hazardous substance component of a mixture indicated in Section II, Part C, list the names of
the releasing sources and their upper bounds. Please use a SEPARATE sheet for EACH hazardous
substance.
Name of Hazardous Substance:
To calculate the SSI trigger (i.e., the upper bound of the normal range of a release) for the hazardous substance identified
above, aggregate the upper bounds of the normal range of the identified hazardous substance across all sources identified in
Section II, Part C. If the hazardous substance is also a component of a mixture, be certain to include the upper bound of the
component as calculated in Section II, Part C, in your calculation of the SSI trigger.

* This methodfor calculating the SSI trigger for the hazardous substance assumes that all releases of the
same hazardous substance or mixture occur simultaneously. To the extent that a hazardous substance is
releasedfrom your facility fi-om different sources and at different frequencies, you may adjust the SSI trigger
as appropriate so that it more accurately reflects the frequency and quantity of the release. The SSI trigger
in the final analysis must reflect the upper bound of the normal range of the release, taking into
consideration all sources of the release at the facility or vessel. The normal range of the release includes all
releases previously reported or occurring over a 24-hour period during the previous year.

SECTION III: SUBSTANCE INFORMATION
CR-ERNS Number:
If you are reporting a release of a CERCLA hazardous substance(s), you will be assigned a CR-ERNS number when you make
this initial telephone call to the NRC (1-800-424-8802). This CR-ERNS number will become the identifier for your facility. Your
CR-ERNS number will never change; it is the number that identifies you in the CR-ERNS database.
After you provide the required information for all sources of continuous releases from your facility, you must aggregate
information of a hazardous substance release from all sources to determine the SSI trigger (upper bound of the normal range)
for each hazardous substance released at your facility.
The SSI trigger of a particular hazardous substance is calculated by aggregating the upper bounds of the hazardous
substance released across all sources at a facility.
If you are aggregating CERCLA hazardous substance releases from separate, contiguous, or adjacent facilities and
reporting them in a single report, aggregate the upper bound of the normal range of the hazardous substance released from all
sources at the site to determine the SSI trigger. If you aggregate your releases across facilities, the SSI trigger must also be site-
specific, not facility-specific. Aggregating releases across facilities at the same site may reduce your reporting burden; however,
EPA will evaluate the risks associated with the releases as if the releases were from one facility.
To calculate the SSI trigger for each hazardous substance you should:
1. List each specific source name and enter the upper bound of the normal range of the release from that source. If the
identified hazardous substance is a component of a mixture, enter the upper bound of the normal range for that
component of the mixture (as determined in Section II, Part C).
2. Aggregate the upper bound quantities from each source of the release. Report these totals as the SSI trigger for the
hazardous substance. The example that is provided below illustrates the calculation of the SSI trigger for a release of
The above method for calculating the SSI trigger of a hazardous substance assumes that all releases of the same
hazardous substance occur simultaneously (i.e., over the same 24-hour period). To the extent that the frequency of the release
differs, you may adjust the SSI trigger so that it more accurately reflects the frequency and quantity of the hazardous substance
released from all sources over a 24-hour period. The SSI trigger in the final analysis must reflect the upper bound of the normal
range of the release, taking into consideration all sources of the release at the facility. The normal range of the release includes
all continuous releases previously reported or occurring over a 24-hour period during the previous year.
