TRI FORM R GUIDANCE DOCUMENT
COALMINING
SECTION 1
INTRODUCTION
This guidance document has been prepared to assist coal mining facilities in complying with the
reporting requirements of Section 313 of the Emergency Planning and Community Right-to-
Know Act (EPCRA, Public Law 99-499, Title IE of the Superfund Amendments and
Reauthorization Act of 1986, hereafter EPCRA Section 313) and Section 6607 of the Pollution
Prevention Act (PPA). This guidance document is intended for use along with the Toxic
Chemical Release Inventory Reporting Form R and Instructions document published annually by
the U.S. Environmental Protection Agency (EPA). For further assistance and to obtain copies of
the latest version of this instruction document, contact the EPCRA Hotline at 1-800-535-0202.
The other EPCRA reporting programs are summarized at the end of this section.
One of the primary goals of the EPCRA program is to increase the public's knowledge of, and
access to, information on both the presence of Section 313 chemicals in their communities and on
releases and other waste management activities of Section 313 chemicals into the environment.
Since 1987, certain facilities in the manufacturing sector have been reporting information on
releases and other waste management activities of Section 313 chemicals to EPA and states
throughout the United States. As a result of an EPA rulemaking (62 FR 23834, May 1,1997),
certain additional industry groups, including coal mining facilities (Standard Industrial
Classification (SIC) Major Group 12), are now required to evaluate their chemical use and waste
management activities to determine potential reporting responsibilities under EPCRA Section 313.
Section 313 establishes annual reporting requirements for Section 313 chemicals provided that
certain activity thresholds are met. Section 313 includes a list of over 650 chemicals and chemical
categories. These chemicals and chemical categories were either originally selected by Congress
or were added by EPA through rulemaking.
The Section 313 reporting requirements apply to owners or operators offacilities which meet all
of the following three criteria:
The facility must be in SIC code 10 (except 1011,1081, and 1094), or 12 (except 1241),
or 20-39 (manufacturing facilities), or 4911 (limited to facilities that combust coal and/or
oil for the purpose of generating power for distribution in commerce), 4931 (limited to
facilities that combust coal and/or oil for the purpose of generating power for distribution
in commerce) and 4939 (limited to those facilities that combust coal and/or oil for the
purpose of generating power for distribution in commerce), or 4953 (limited to facilities
regulated under RCRA subtitle C), or 5169, or 5171;, or 7389 (limited to facilities
primarily engaged in solvent recovery services on a contract or fee basis); and,

COALMINING
The facility must have 10 or more full-time employees (or the total hours worked by all
employees is greater than 20,000 hours), and
The facility manufactures (defined to include importing), processes, or otherwise uses any
Section 313 chemical in quantities greater than the established threshold in the course of a
calendar year.
For each Section 313 chemical or chemical category, covered facilities must report the total
annual releases, both routine and accidental, to all environmental media; and other on-site waste
management activities, including quantities recycled, combusted for energy recovery and treated
for destruction, and off-site transfers for disposal, waste treatment, energy recovery and recycling.
This information is submitted on the Toxic Chemical Release Inventory (TRI) Reporting Form,
which is called the "Form R." (As discussed in the following chapter, facilities meeting certain
conditions are eligible to report using an abbreviated Form A.)
The annual Form R or Form A reports are submitted to EPA headquarters and to a state
designated agency, usually a State Emergency Response Commission (SERC) but may be a Tribal
Emergency Response Comission (TERC), annually on or before July 1st for activities occurring
during the previous calendar year (e.g., July 1, 1999, for activities during the period from January
1 to December 31,1998).
EPCRA mandated that EPA establish and maintain a national TRI database to assist in research
and the development of regulations, guidelines, and standards related to Section 313 chemicals
and to make the TRI data available to the general public and any interested parties. The TRI
database is computer-accessible to anyone with a modem via the National Library of Medicine's
TOXNET on-line system. The TRI data are also available through many other sources, including
EPA's Internet Web site; public libraries on microfiche; the Government Printing Office on CD-
ROM; and the National Technical Information Service on magnetic tape and individual state
diskettes.
Facility owners or operators who violate the Section 313 reporting provisions may be assessed
civil penalties of up to $25,000 per day for each violation. In addition, state enforcement
provisions may also be applicable depending on the state's EPCRA Section 313 reporting
regulations.
This document is organized into several sections to provide quick reference. Section 2 presents
an overview of the Section 313 reporting requirements. Section 3 provides a detailed discussion
of how to make threshold determinations regarding the manufacture, processing, and otherwise
use of Section 313 chemicals. Section 4 covers general concepts relating to reporting and release
estimating, and provides potential data sources for determining releases at coal mining facilities

and other amounts managed. Section 5 presents a detailed discussion of EPCRA Section 313
release and other waste management scenarios in the coal mining industry and covers developing
estimates of releases and other waste management activities for several types of operations
commonly encountered by the coal mining industry. Finally, Appendix A provides an alphabetical
listing of the Section 313 chemicals and chemical categories subject to EPCRA Section 313, the
de minimis concentrations for each Section 313 chemical, and the RCRA status of the chemical.
Appendix B provides a bibliography of relevant EPA documents used to help coal mining facilities
in complying with EPCRA Section 313. Appendix C provides relevant on-line information
sources. ;

Reporting Requirements
Sections
302 - 303
Presence of
Extremely
Hazardous
Substances
(40CFR
§355.30)
If a facility has one or more "extremely hazardous substances" present on site in
quantities greater than Threshold Planning Quantities (TPQs) established by EPA, it must
notify its State Emergency Response Commission (SERC) and Local Emergency
Planning Committee (LEPC) that it is subject to the emergency planning requirements of
these sections. A facility representative must be designated to participate in the local
emergency planning process. The facility also must provide any information deemed
necessary for development or implementation of a local emergency plan.
Section 304
Emergency
Notification
(40CFR
§355.40)
A facility must notify the LEPC and SERC immediately of the release of any "extremely
hazardous substance" (listed in 40 CFR Part 355, Appendices A and B) or any hazardous
substance under CERCLA (listed in 40 CFR §302.4), in amounts at or above the
specified Reportable Quantities that EPA establishes for each substance. The facility
must follow up this initial notification with a written statement providing details of the
incident.
Section 311
Material
Safety Data
Sheet
(MSDS)
Reporting
(40 CFR
§370.21)
A facility must submit to the LEPC, SERC, and local fire department a list of Material
Safety Data Sheets (MSDSs), or copies of MSDSs, for any "hazardous chemicals" (as
defined under the Occupational Safety and Health Administration (OSHA) Hazard
Communication Standard) that are present on site in quantities greater than 10,000
pounds. A facility also must report any "extremely hazardous substances" (EHS) (as
defined under Section 302) that are present on site in quantities at or above the TPQ or
500 pounds, whichever is less. Submissions are required within 90 days of the date when
new chemicals are first present at or above specified thresholds or if new information on
previously reported chemicals becomes available. Some states have established lower
activity thresholds.
Section 312
Hazardous
Chemical
Inventory
(40 CFR
§370.25)
A facility must submit to the LEPC, SERC, and local fire department certain information
for any "hazardous chemical" or EHS reportable under Section 311. This information
is most commonly submitted on a Tier I or Tier H Form and includes a description of any
type of hazard the material may pose, the quantities stored, general storage locations, and
type of storage. The reports for each calendar year are due on or before March 1 of the
following year. Most states require or request that facilities submit the more detailed Tier
II reporting form or a state-issued version of that form. In addition, some states have
established lower activity thresholds and require more detailed or additional information.

Reporting
(FormR)
(40CFR
§372)
A facility in certain SIC codes meeting threshold requirements is required to report
annually amounts of listed Section 313 toxic chemicals released or otherwise managed
to EPA and designated state agencies. Section 313 includes a list of over 650
chemicals and chemical categories. Release reporting information is submitted on the
Toxic Chemical Release Inventory (TRI) Reporting Form, Form R or Form A.
The Section 313 reporting requirements apply to owners or operators of facilities
which meet all of the following three criteria:;
Facility must be in SIC code 10 (except 1011, 1081, and 1094), or 12 (except
1241), or 20-39 (manufacturing facilities), or 4911 (limited to facilities that
combust coal and/or oil for the purpose of generating power for distribution in
commerce), 4931 (limited to facilities that combust coal and/or oil for the
purpose of generating power for distribution in commerce) and 4939 (limited
to faculties that combust coal and/or oil for the purpose of generating power
for distribution in commerce), or 4953 (limited to facilities regulated under
RCRA subtitle C), or 5169, or 5171, or 7389 (limited to facilities primarily
engaged in solvent recovery services on a contract or fee basis); and.
Facility must have 10 or more full-time employees (or the total hours worked
by all employees is greater than 20,000 hours), and
» Facility must manufacture (including importation), process, or otherwise use a
listed Section 313 chemical in excess:of specific threshold quantities.
The threshold quantities for reporting under Section 313 are based on the amount of
the Section 313 chemical manufactured, processed, or otherwise used during the
calendar year. Specifically, the thresholds are greater than 25,000 pounds if
manufactured, or 25,000 pounds if processed, or 10,000 pounds if otherwise used.
EPCRA mandated that EPA establish and maintain a national TRI database to assist in
research and the development of regulations, guidelines, and standards related to
Section 313 chemicals and to make the TRI data available to the general public and
any interested parties. The TRI database is computer-accessible to anyone with a

SECTION 2
SECTION 313 REPORTING REQUIREMENTS
WHO MUST REPORT?
A facility is subject to the provisions of the Section 313 reporting requirements if it meets all three
of the following criteria:
The facility must be in SIC code 10 (except 1011,1081, and 1094), or 12 (except 1241),
or 20-39 (manufacturing facilities), or 4911 (limited to facilities that combust coal and/or
oil for the purpose of generating power for distribution in commerce), 4931 (limited to
facilities that combust coal and/or oil for the purpose of generating power for distribution
in commerce) and 4939 (limited to facilities that combust coal and/or oil for the purpose
of generating power for distribution in commerce), or 4953 (limited to facilities regulated
under RCRA subtitle C), or 5169, or 5171, or 7389 (limited to facilities primarily engaged
in solvent recovery services on a contract or fee basis) hereafter "covered SIC codes";
and,
Facility must have 10 or more full-time employees (or the total hours worked by all
employees is greater than 20,000 hours), and
The facility manufactures (defined to include importation), or processes, or otherwise uses
any Section 313 chemical in quantities greater than the established threshold in the course
of a calendar year.
Instructions regarding how to determine the facility SIC code, employee threshold, or activity
follows; for additional detail please consult the Toxic Chemical Release Inventory Reporting
Form R and Instructions, a document published annually by EPA.
In addition, pursuant to Executive Order (EO) 12856 signed by the President on August 3,1993,
Federal facilities are required to determine the applicability of the EPCRA Section 313 reporting
requirements regardless of the facility's SIC codes. Federal facilities that have 10 or more full
time employees or the equivalent and manufacture, process, or otherwise use listed Section 313
chemicals at or above established thresholds are subject to EPCRA Section 313 reporting.
Federal facilities were required to begin reporting no later than reporting year 1994; their first
Form R or Form A reports were due by July 1,1995.
The amount of the chemical released to the environment does not affect the need to report. Even
if there are no releases of a listed Section 313 chemical, a facility must report if it meets the
September 26,1997 2^1 ~~
-------
TRI FORM R GUIDANCE DOCUMENT
COALMINING
requirements regarding SIC code, number of employees, and activity threshold. A threshold
determination must be made individually for each Section 313 chemical.
Thresholds are based on operation year, this includes partial year reporting and reporting by a
facility that is going through closure. The facilities should consider the portion of the year for
which they operated to determine the actual employee hours worked as well as threshold
determination and release reporting. :
Reduced Reporting
On November 30,1994, EPA published a final rule (59 FR 61488) that provides an alternative
reporting option to qualifying facilities. Eligible facilities wishing to take advantage of this
alternative reporting option may report on a simplified two page form referred to as Form A and
do not have to use Form R. The rule entitled "TRI Alternate Threshold for Facilities with Low
Annual Reportable Amounts," provides facilities that otherwise meet EPCRA Section 313 activity
thresholds the option of reporting on Form A, provided that they do not exceed 500 pounds for
the total annual reportable amount (defined below) for that chemical, and that the amounts
manufactured, processed or otherwise used do not exceed 1 million pounds. As with determining
an activity threshold to determine if the chemical activity has been exceeded, facilities must
evaluate each activity threshold separately; for example, a facility that manufactures 900,000
pounds per year of a Section 313 chemical and processes 150,000 pounds per year of a Section
313 chemical would still be eligible to use the Form A.
For the purpose of reporting on Form A, the annual reportable amount is equal to the combined
total quantities released (including disposed) at the facility, treated at the facility (as represented
by amounts destroyed or converted by treatment processes), recycled at the facility, combusted
for the purpose of energy recovery at the facility, and amounts transferred from the facility to off-
site locations for the purpose of recycling, energy recovery, treatment, and/or disposal. These
quantities do not include amounts of the chemical accidentally released. These volumes
correspond to the sum of amounts reported on Form R, as Part n column B of section 8, data
elements 8.1 (quantity released), 8.2 (quantity used for energy recovery on-site), 8.3 (quantity
used for energy recovery off-site), 8.4 (quantity recycled on-site), 8.5 (quantity recycled off-site),
8.6 (quantity treated on-site), and 8.7 (quantity treated off-site). See Section 4 of this document
for more guidance on completing Part n, Section 8 of Form R.
What is a Facility?
Under EPCRA, a "facility" is defined as all buildings, equipment, structures, and other stationary
items which are located on a single site or contiguous or adjacent sites and which are owned or
operated by the same person (or by any person which controls, is controlled by, or under common
control with such person). An "establishment" is generally a single physical location, where
September 26,1997

-------
TRI FORM R GUIDANCE DOCUMENT
COALMINING
business is conducted or where services or industrial operations are performed. A facility may
contain more than one establishment. For example, a mine, mill, and smelter would be one facility
if aU three units were owned and operated by the same company and are located on contiguous or
adjacent properties. A single facility therefore can be a multi-establishment complex. Such a
facility may submit reports that cover all its establishments, or the individual establishments may
report separately. However, for the purposes of determining thresholds, all chemical activities for
the entire facility must be considered.
How to Determine Your SIC Code*
Standard Industrial Classification (SIC) codes 10 (except 1011, 1081, and 1094), 12 (except
1241), 20-39 (manufacturing facilities), 4911,4931 and 4939 (limited to facilities that combust
coal and/or oil for the purpose of generating power for distribution in commerce), 4953 (limited
to facilities regulated under RCRA subtitle C), 5169, 5171, and 7389 (limited to facilities
primarily engaged in solvent recovery services on a contract or fee basis) are covered under
section 313 of EPCRA. The first two digits of a 4-digit SIC code define a major business sector,
while the last two digits denote a facility's specialty within the major sector. A facility should
determine its own SIC code(s), based on its activities on-site and the "Standard Industrial
Classification Manual 1987." In some cases, a state agency or other organization may have
assigned SIC codes on a different basis than the one used in the SIC Manual. For the purposes of
TRI reporting, state assigned codes should not be used if they differ from ones assigned using the
SIC Manual.
Your facility may include multiple establishments that have different SIC codes. In order to
determine which SIC code best represents the facility, the facility should calculate the value of the
products or services produced or provided at/by or shipped from each establishment within the
facility and then use the following rule to determine if your facility comes within the covered SIC
codes, and the SIC code criterion is met.
If the total value of the products or services shipped, produced or provided at establishments
in "covered" SIC codes is greater than 50 percent of the value of the entire facility's products
and services, the entke facility comes within the covered SIC codes, and the SIC code
criterion is met.
Please note: The North American Industrial Classification System that appeared in the Federal Register on
April 9,1997 will replace the 1987 Standard Industrial Classification System (SIC). Regulatory entities, including
EPA, will take steps to adopt the new classification system over the next few years. In the meantime, facilities should
consider their activities in relation to the 1987 SIC code system.
September 26,1997 2^3~~
-------
TRI FORM R GUIDANCE DOCUMENT
COALMINING
If any one establishment in the specified set of SIC codes produces, provides or ships products
or service whose value exceeds the value of products and services produced or shipped by all
other establishments within the facility, the facility comes within the covered SIC codes, and
the SIC code criterion is met.
The value of production or service attributable to a particular establishment may be isolated by
subtracting the product or service value obtained from other establishments within the same
facility from the total product or service value of the facility. This procedure eliminates the
potential for "double counting" production or service in situations where establishments are
engaged in sequential production activities at a single facility.
How to Determine Your Number of Employees
A "full time employee," for the purpose of Section 313 reporting, is defined as 2,000 work hours
per year. The number of full time employees is dependent only upon the total number of hours
worked by all employees during the calendar year for that facility and not the number of persons
working. To determine the number of full time employees working for your facility, add up the
hours worked by all employees during the calendar year including contract employees and sales
and support staff, and divide the total by 2,000 hours. In other words, if the total number of
hours worked by all employees is 20,000 hours or more, your facility meets the ten employee
threshold.
Facilities may have contract workers present at times to conduct maintenance and service
operations, including equipment, motor vehicle, and building maintenance, construction, and
operating processes and waste management activities (e.g., remediation). The hours of all these
contract workers count toward the employee threshold for reporting under Section 313. In
addition, the hours worked by professionals (e.g., those on salary, that do not clock in or out) also
count towards the facility's employee threshold. Employees that perform activities which
routinely occur off-site such as truck drivers, but who are base
-------
TRI FORMRGUIDANCE DOCUMENT COALMINING
three categories when determining whether an activity threshold has been exceeded. These
categories are:
Manufacture - "Manufacture" means to produce, prepare, compound, or import a listed
Section 313 chemical Import is defined as causing the Section 313 chemical to be imported
into the customs territory of the United States. If you order a listed Section 313 chemical (or
a mixture containing the chemical) from a foreign supplier, then you have imported the
chemical when that shipment arrives at your facility directly from a source outside of the
United States. By ordering the chemical, you have "caused it to be imported," even though
you may have used an import brokerage firm as an agent to obtain the Section 313 chemical.
If the importation was directed by the parent company, then the facility receiving the chemical
is not considered to have imported the chemical.
The term manufacture also includes coincidental production of a listed chemical (e.g., as a
byproduct or impurity) as a result of the manufacture, processing, otherwise use, or waste
management of other chemical substances. The fact that the coincidental manufacturing of
these byproducts is not the primary purpose of coal mining is irrelevant. Listed EPCRA
Section 313 chemicals coincidentally manufactured by a facility must be factored into
threshold determinations and release calculations.
Manufactured Activities and Definitions
Produced or imported for on-site use/processing
A chemical that is produced or imported and then further processed or
otherwise used at the same facility.
Produced or imported for sale/distribution
A chemical that is produced or imported specifically for sale or
distribution outside the facility.
Produced as a by-product
A chemical that is produced coincidentally during the production,
processing, otherwise use, or disposal of another chemical substance or
mixture and, following its production, is separated from that other
chemical substance or mixture. Section 313 chemicals produced and
released as a result of waste treatment for disposal are also considered
byproducts.
Produced as an impurity
A chemical that is produced coincidentally as a result of the
manufacture, processing, or otherwise use of another chemical but is

COALMINING
not separated and remains primarily in the mixture or product with that
other chemical. :
Process - "Process" means the preparation of a listed Section 313 chemical, after its
manufacture, for distribution in commerce. Processing is usually the intentional incorporation
of a Section 313 chemical into a product. Processing includes preparation of the Section 313
chemical in the same physical state or chemical form as that received by your facility, or
preparation that produces a change in physical state or chemical form. The term also applies
to the processing of a mixture or other trade name product that contains a listed Section 313
chemical as one component. Processing activities include use of Section 313 chemicals as
reactants, in formulations, and as article components, and repackaging. Processing may also
include the recycling of a Section 313 chemical for distribution in commerce. For example, if
a facility receives a waste containing a Section 313 chemical from off-site, stabilizes, and
repackages the waste in one calendar year and then distributes the repackaged waste into
commerce in the following year. The facility would count the amount of the Section 313
chemical stabilized as being processed in the year it was treated.
Relabeling or redistributing of the Section 313 chemical where no repackaging of the Section
313 chemical occurs does not constitute processing of the Section 313 chemical.
Processed Activities and Definitions '
As a reactant
A natural or synthetic chemical used in chemical reactions for the
manufacture of another chemical substance or product. This includes,
but is not limited to, feedstocks, raw materials, intermediates, and
initiators. :
As a formulation component
A chemical added to a product (or product mixture) prior to further
distribution of the product that acts as a performance enhancer during
use of the product. Examples of Section 313 chemicals used in this
capacity include, but are not limited to, additives, dyes, reaction
diluents, initiators, solvents, inhibitors, emulsifiers, surfactants,
lubricants, flame retardants, and rheological modifiers.
As an article component
A chemical that becomes an integral component of an article distributed
for industrial, trade, or consumer use.

* Repackaging
Processing or preparation of a Section 313 chemical (or product
mixture) for distribution in commerce in a different form, state, or
quantity. This includes, but is not limited to, the transfer of material
from a bulk container, such as a tank truck, to smaller containers such
as cans or bottles.
Otherwise use - Any use involving a listed Section 313 chemical at a facility that does not fall
under the definitions of 'manufacture" or "process" is an otherwise use of that chemical. A
chemical that is otherwise used by a facility is not incorporated into a product distributed in
commerce and includes use of the Section 313 chemical as a chemical processing aid or as a
manufacturing aid or for ancillary uses such as treating wastes. Otherwise use of a Section
313 chemical does not include disposal, stabilization (without subsequent distribution in
commerce), or treatment for destruction unless:
(1) The Section 313 chemical that was disposed, stabilized, or treated for destruction
was received from off-site for the purposes of further waste management, or
(2) The Section 313 chemical that was disposed, stabilized, or treated for destruction
was manufactured as a result of waste management activities on materials received
from off-site for the purpose of further waste management.
Relabeling or redistributing of the Section 313 chemical where no repackaging of the Section
313 chemical occurs does not constitute the otherwise use of the Section 313 chemical.
Otherwise Used Activities and Definitions
As a chemical processing aid
A chemical that is added to a reaction mixture to aid in the manufacture
or synthesis of another chemical substance but is not intended to remain
in or become part of the product or product mixture. Examples of such
Section 313 chemicals include, but are not limited to, process solvents,
catalysts, inhibitors, initiators, reaction terminators, and solution
buffers.
As a manufacturing aid
A chemical that aids the manufacturing process that does not become
part of the resulting product and is not added to the reaction mixture
during the manufacture or synthesis of another chemical substance.

Examples include, but are not limited to, process lubricants,
metalworking fluids, coolants, refrigerants, and hydraulic fluids.
Ancillary or other use '
A chemical that is used at a facility for purposes other than aiding
chemical processing or manufacturing as described above. Examples of
such Section 313 chemicals include, but are not limited to, cleaners,
degreasers, lubricants, fuels, and chemicals used for treating wastes.
For purposes of the otherwise use definition, EPA interprets waste management activities to
include recycling, combustion for energy recovery, treatment fpr destruction, waste stabilization,
and release, including disposal. Waste management does not include the storage, container
transfer, or tank transfer of a Section 313 chemical if no recycling, combustion for energy,
treatment for destruction, waste stabilization, or release of thelchemical occurs at the facility.
(See 62 FR 23850)
Recycling for the purposes of EPCRA Section 313 means the following: (1) the recovery for
reuse of a Section 313 chemical from a gaseous, aerosol, aqueous, liquid, or solid stream; or (2)
the reuse or the recovery for use of a Section 313 chemical that is a RCRA hazardous waste as
defined in 40 CFR Part 261. Recovery is the act of extracting or removing the Section 313
chemical from a waste stream and includes: (1) the reclamation of the Section 313 chemical from
a stream that entered a waste treatment or pollution control device or process where destruction
of the stream or destruction or removal of certain constituents of the stream occurs (including air
pollution control devices or processes, wastewater treatment or control devices or processes,
Federal or state permitted treatment or control devices or processes, and other types of treatment
or control devices or processes); and (2) the reclamation for reuse of an "otherwise used" Section
313 chemical that is spent or contaminated and that must be recovered for further use in either the
original or any other operations. (See EPA document, Interpretations of Waste Management
Activities: Recycling, Combustion for Energy Recovery, Waste Stabilization and Release.)
i
Combustion for energy recovery is interpreted by EPA to include the combustion of a Section
313 chemical that is (1) (a) a RCRA hazardous waste or waste fuel, (b) a constituent of a RCRA
hazardous waste or waste fuel, or a spent or contaminated "otherwise used" material; and that (2)
has a heating value greater than or equal to 5,000 British thermal units (BTU) per pound in an
energy or materials recovery device. Energy or materials recovery devices are boilers and
industrial furnaces as defined in 40 CFR §372.3 (See 62 FR 23891). In determining whether an
EPCRA Section 313 listed toxic chemical is combusted for enbrgy recovery, the facility should
consider the BTU value of the Section 313 chemical and not of the chemical stream. If the
heating value of the Section 313 chemical is below 5,000 BTU/lb., the chemical is being treated
for destruction. A facility that blends and subsequently distributes in commerce a waste-derived

fuel "processes" EPCRA Section 313 listed toxic chemicals that are constituents of that waste-
derived fuel. In contrast, if subsequent to blending the waste-derived fuel, that same facility
combusts on-site the waste-derived fuel in an energy recovery unit, the facility "otherwise uses"
EPCRA Section 313 listed toxic chemicals that are constituents of that waste-derived fuel. An
EPCRA Section 313 listed toxic chemical that has a heat value of less than 5,000 BTU/tb. and
that is a constituent of a waste-derived fuel is "otherwise used" if that fuel is combusted in an on-
site energy recovery unit (62 FR 23851).
EPA defines Treatment for destruction to mean the destruction of a Section 313 chemical in
waste such that the substance is no longer the Section 313 chemical subject to reporting under
EPCRA Section 313. Treatment for destruction does not include the destruction of a Section 313
chemical in waste where the Section 313 chemical has a heat value greater than 5,000 British
Thermal Units (BTU) and is combusted in any device that is an industrial boiler or furnace. (See
40 CFR §372.3.) "Treatment for destruction" includes acid or alkaline neutralization if the
Section 313 chemical is the entity that reacts with the acid or base. "Treatment for destruction"
does not include: (1) neutralization of a waste stream containing Section 313 chemicals if the
Section 313 chemicals themselves do not react with the acid or base (See 40 CFR §372.3), (2)
preparation of a Section 313 chemical for disposal, (3) removal of Section 313 chemicals from
waste streams, and (4) activities intended to render a waste stream more suitable for further use
or processing, such as distillation or sedimentation. For example, neutralization of pure nitric acid
is considered treatment for destruction. In contrast, neutralization of nitric acid containing three
percent lead is not considered treatment for destruction of the lead component, because the lead
has not reacted with the neutralizing agent (See 62 FR 23852).
EPA defines Waste stabilization to mean any physical or chemical process used to either reduce
the mobility of hazardous constituents in a hazardous waste or eliminate free liquid as determined
by a RCRA approved test method (e.g., Test Method 9095). A waste stabilization process
includes mixing the hazardous waste with binders or other materials and curing the resulting
hazardous waste and binder mixture. Other synonymous terms used to refer to this process are
"stabilization," "waste fixation," or "waste solidification." (See 40 CFR §372.3.)
Release is defined by EPCRA Section 329(8) to mean any spilling, leaking, pumping, pouring,
emitting, emptying, discharging, injecting, escaping, leaching, dumping, or disposing into the
environment (including the abandonment or discarding of barrels, containers, and other closed
receptacles) of any Section 313 chemical. (See 40 CFR §372.3.)
Disposal is defined by EPCRA to mean any underground injection, placement in landfills/surface
impoundments, land treatment, or other intentional land disposal. (See 40 CFR §372.3.)

COALMINING
Based on EPA's evaluation of the coal mining industry, the Agency believes that coal mining
activities routinely involve or result in the manufacturing, processing, or otherwise use of EPCRA
Section 313 chemicals (62 FR 23834, May 1,1997). The term manufacture includes the
coincidental manufacture of a chemical, such as a byproduct or impurity, from the manufacturing,
processing, otherwise use or waste management of another chemical substance or mixture.
Thresholds must be calculated separately for manufacture, process, or otherwise use of the same
chemical. If any single threshold is exceeded for a listed Section 313 chemical, the facility must
submit a Form R covering all nonexempt activities. Coal mining facilities will be required to
factor into their threshold determinations and reporting calculations the quantities of EPCRA
Section 313 chemicals used in support activities such as froth flotation, non-motor vehicle
equipment maintenance, and dewatering. Chemicals involved in these support activities are
classified under the otherwise use category.
EXEMPTIONS
I
Section 313 provides for exemptions from reporting for specific "processing" or "otherwise use"
activities. The instructions provided in Toxic Chemical Release Inventory Reporting Form R and
Instructions should be reviewed carefully before proceeding. :The following discussion
summarizes the exemption instructions. A facility does not have to consider amounts of listed
Section 313 chemicals involved in any of these processing or otherwise use activities when
determining if activity thresholds have been exceeded or when estimating environmental releases.
Limited exemptions apply to manufacturing activities. For example, manufacturing a Section 313
chemical for research and development purposes and manufacturing as an impurity below a
specified level in a product distributed beyond the facility both can be exempt. The EPA's Toxic
Chemical Release Inventory Questions and Answers, Revised 1990 Version [EPA 560/4/91-003
(will be revised in near future)] and the Toxic Release Inventory Reporting Form R and
Instructions also contain information about these exemptions. (See Appendix B for ordering
information.)
The de minimis exemption allows facilities to disregard certain minimal concentrations of
chemicals in mixtures or trade name products they "process" or "otherwise use" in making
threshold determinations and release and other waste management determinations. The de
minimis exemption does not apply to the "manufacture" of a Section 313 chemical except if
that Section 313 chemical is "manufactured" as an impurity and remains in the product
distributed in commerce below the appropriate de minimis level. The de minimis exemption
does not apply to a byproduct "manufactured" coincidentally as a result of "manufacturing,"
"processing," "otherwise use," or any waste management activities.
September 26,1997
2-10
-------
TRI FORM R GUIDANCE DOCUMENT
COALMINING
This de minimis exemption applies solely to "mixtures" and trade name products. EPA's
long-standing interpretation has been that "mixture" does not include waste. Therefore, the
de minimis exemption cannot be applied to Section 313 chemicals in a waste even if the waste
is being "processed" or "otherwise used."
When determining whether the de minimis exemption applies to a listed Section 313 chemical,
the owner or operator should only consider the concentration of the Section 313 chemical in
mixtures and trade name products in process streams in which the Section 313 chemical is
undergoing a reportable activity. If the Section 313 chemical in a process stream is
"manufactured" as an impurity, "processed," or "otherwise used" and is below the appropriate
de minimis concentration level, then the quantity of the Section 313 chemical in that process
stream does not have to be applied to threshold determinations nor included in release or
other waste management determinations. If a Section 313 chemical in a process stream meets
the de minimis exemption, all releases and other waste management activities associated with
the Section 313 chemical in that stream are exempt from EPCRA section 313 reporting. It is
possible to meet an activity (e.g., processing) threshold for a Section 313 chemical on a
facility-wide basis, but not be required to calculate releases or other waste management
quantities associated with a particular process because that process involves only mixtures or
trade name products containing the Section 313 chemical below the de minimis level.
Once a Section 313 chemical concentration is above the appropriate de minimis
concentration, threshold determinations and release and other waste management
determinations must be made, even if the chemical later falls below de minimis level in the
same process stream. Thus, all releases and other quantities managed as waste which occur
after the de minimis level has been exceeded are then subject to reporting. If a Section 313
chemical in a mixture or trade name product above de minimis is brought on-site, the de
minimis exemption never applies.
The de minimis concentration level is consistent with the OSHA Hazard Communication
Standard requirements for development of Material Safety Data Sheets (MSDSs). The de
minimis level is 1.0 percent except if the Section 313 chemical is an OSHA-defined
carcinogen. The de minimis level for OSHA-defined carcinogens is 0.1 percent. For mixtures
or other trade name products that contain one or more members of a listed Section 313 toxic
chemical category, the de minimis level applies to the aggregate concentration of all such
members and not to each individually. The list of Section 313 chemicals in the publication
Toxic Chemical Release Inventory Reporting Form R and Instructions for the current
reporting year contains the de minimis values for each of the Section 313 chemicals and
chemical categories.

Materials that are processed or used as articles - Quantities of a listed Section 313
chemical contained in an article do not have to be factored into threshold or release
determinations when that article is processed or otherwise used at your facility. An article is
defined as a manufactured item that is formed to a specific shape or design during
manufacture, that has end-use functions dependent in whole or in part upon its shape or
design during end-use, and that does not release a Section 313 chemical under the normal
conditions of the processing or use of that item at the facility.
i
If the processing or otherwise use of like articles results in a total release of less than 0.5
pounds of a Section 313 chemical in a calendar year to all environmental media, EPA will
allow this release quantity to be rounded to zero, and the manufactured items remain exempt
as articles. EPA requires facilities to round off and report all estimates to the nearest whole
number. The 0.5-pound limit does not apply to each individual article, but applies to the sum
of all releases from processing or otherwise use of like articles.
The article exemption applies to the normal processing or otherwise use of an article. It does
not apply to the manufacture of an article. Thus, Section; 313 chemicals processed into
articles manufactured at a facility must be factored into threshold and release determinations.
A closed item containing Section 313 chemicals (e.g., a transformer containing PCBs) that
does not release the Section 313 chemicals during normal use is considered an article if a
facility uses the item as intended and the Section 313 chemicals are not released. If a facility
services the closed item (e.g., a transformer) by replacing the Section 313 chemicals, the
Section 313 chemicals added during the reporting year must counted in threshold
determinations. ;
Materials that are structural components of the facility - Chemicals present in materials
used to construct, repair, or maintain a plant building are exempt from the activity thresholds.
For example, solvents and pigments present in paint used to coat the structural components of
a building would be exempt from threshold determination and release reporting.
Materials used for janitorial or facility grounds maintenance - Chemicals present in
materials used for routine or facility grounds maintenance are exempt from the activity
thresholds. Examples include bathroom cleaners, fertilizers, and garden pesticides in the same
form and concentration commonly distributed to consumers. Chemicals used for equipment
maintenance, such as the use of oil or cleaning solvents, are not exempt.

Materials used with facility motor vehicles - Chemicals present in materials used for
operating and maintaining motor vehicles operated by the facility are exempt from the activity
thresholds. Examples include gasoline, radiator coolant, and windshield wiper fluid used in
equipment such as cars, trucks, forklifts, and tow motors.
Personal items - Chemicals present in materials such as foods, drugs, cosmetics, or other
personal items are exempt from the activity thresholds. Examples include materials used in the
facility cafeteria and infirmary. Chemicals used for heating and air conditioning solely to
provide comfort to personnel are also exempt from reporting. If a building's temperature is
regulated to facilitate a process or treatment operation, the Section 313 chemicals used to heat
or cool the building are not exempt. Units that supply both personal comfort and operational
needs may be apportioned, if it is possible to separate them.
Laboratory materials - Chemicals used in certain laboratory activities that are conducted
under the supervision of a technically qualified individual (as defined under 40 CFR
§720.3(ee)) are exempt from the activity thresholds. The laboratory activities exemption
applies only to sampling and analysis, research and development, and quality assurance and
quality control activities. The exemption does not apply to the use or production of listed
Section 313 chemicals in pilot-plant operations and laboratories for distribution in commerce
(e.g., specialty chemicals) and laboratory support services.
Materials as they are drawn from the environment or municipal sources - Chemicals
contained in intake water (used for processing or non-contact cooling) or in intake air (used
either as compressed air or for combustion) are exempt from the activity thresholds.
Property owners - Property owners that merely own real estate on which a facility covered
by Section 313 is located and have no business interest in the operation of that facility (e.g., a
company owns an industrial park) are exempt for Section 313 reporting. The operator of that
facility, however, is subject to reporting requirements.
SUPPLIER NOTIFICATION REQUIREMENTS
Because manufacturers reporting under Section 313 must know the Section 313 chemical
composition of the products they use to be able to accurately calculate releases, EPA requires
some suppliers of mixtures or trade name products containing one or more of the listed Section
313 chemicals to notify their customers of the identity of the chemical in the mixture or the trade
name product. This requirement has been in effect since January 1,1989.

A facility must comply with the Section 313 supplier notification requirements if it owns or
operates a facility which meets all of the following criteria.
The facility is in SIC codes 20-39,
The facility manufactures, imports, or processes a Section 313 chemical, and
The facility sells or otherwise distributes in commerced mixture or trade name product

LISTED SECTION 313 CHEMICALS
i
Appendix A to this document contains an alphabetical listing of the chemicals subject to Section
313 reporting at the time of publication of this document, including their de minimis
concentrations. EPA publications Common Synonyms for Section 313 Chemicals (EPA 745-R-
95-008) and Consolidated List of Chemicals Subject to Reporting Under the Act (Title III List of
Lists) (EPA-550-B-96-015) may also be useful references when reviewing the chemicals at your
facility for Section 313 coverage. '
The list of Section 313 chemicals is amended frequently. Users of this guidance document or
other documents listing Section 313 chemicals are cautioned that changes may have occurred to
the list of Section 313 chemicals since publication of the original list or addition of the chemical
through administrative action. The list of Section 313 chemicals presented in the Toxic Chemical
Release Inventory Reporting Form R and Instructions for the current reporting year should
always be consulted as the most up-to-date source of currently listed Section 313 chemicals. For
the latest information on Section 313 chemical listings, contact the EPCRA Hotline at 1-800-535-
0202. '
Some of the Section 313 chemicals have qualifiers included with thek names. Reporting on these
chemicals are determined by the conditions specified in the qualifiers. Chemicals that are listed
September 26,1997

-------
TRI FORM R GUIDANCE DOCUMENT
COALMINING
without parenthetic qualifiers are subject to reporting in all forms in which they are manufactured,
processed, or otherwise used. Descriptions of the qualifiers are as follows:
Fume or dust - Three of the metals on the list of Section 313 chemicals (aluminum,
vanadium, and zinc) contain the qualifier "fume or dust." Fume or dust refers to dry forms of
these metals, not to "wet" forms such as solutions or slurries. Thus, a facility should
determine if, for example, it generated more than 25,000 pounds of "aluminum (fume or
dust)." Similarly, there may be certain technologies in which one of these metals is processed
in the form of a fume or dust to make other Section 313 chemicals or other products for
distribution in commerce. In reporting releases, the facility would report only releases of the
fume or dusts.
EPA considers dusts to consist of solid particles generated by any mechanical processing of
materials including crushing, grinding, rapid impact, handling, detonation, and decrepitation of
organic and inorganic materials such as rock, ore, and metal. Dusts do not tend to flocculate,
except under electrostatic forces. A fume is an airborne dispersion consisting of small solid
particles created by condensation from a gaseous state, in distinction to a gas or vapor.
Fumes arise from the heating of solids such as aluminum. The condensation is often
accompanied by a chemical reaction such as oxidation. Fumes flocculate and sometimes
coalesce. Other metals, (e.g., such as lead or copper) are not limited by this qualifier and are
subject to reporting in all forms (fume, dust, and wet).
Manufacturing qualifiers -Two of the entries in the Section 313 chemical list contain a
qualifier relating to manufacture. For isopropyl alcohol, the qualifier is "manufacturing -
strong acid process". For saccharin the qualifier simply is "manufacturing." For isopropyl
alcohol, the qualifier means that only facilities manufacturing isopropyl alcohol by the strong
acid process are required to report. In the case of saccharin, only manufacturers of the
Section 313 chemical are subject to the reporting requirements. A facility that processes or
otherwise uses either Section 313 chemical would not be required to report for those
chemicals. In both cases, the facility is not required to provide supplier notification because
only the manufacturer, not the user, of the Section 313 chemical must report.
Ammonia (includes anhydrous ammonia and aqueous ammonia from water dissociable
ammonium salts and other sources; 10 percent of total aqueous ammonia is reportable
under this listing) - The qualifier for ammonia means that anhydrous forms of ammonia are
100 percent reportable and aqueous forms are limited to 10 percent of total aqueous
ammonia. Therefore, when determining thresholds, releases, and other waste management
quantities all anhydrous ammonia is included but only 10 percent of total aqueous ammonia is
included. Any evaporation of ammonia from aqueous ammonia solutions is considered
September 26, 1997

-------
TRI FORM R GUIDANCE DOCUMENT
COALMINING
anhydrous ammonia and should be included in the appropriate threshold and release
determinations.
Phosphorus (yellow or white) - The listing for phosphorus is qualified by the term "yellow
or white" This means that only manufacturing, processing, or otherwise use of phosphorus in
the yellow or white chemical forms require reporting. Conversely, manufacturing, processing,
or otherwise use of "black" or "red" phosphorus does not trigger reporting.
Asbestos (friable) - The listing for asbestos is qualified by the term "friable," referring to the
physical characteristic of being able to be crumbled, pulverized, or reducible to a powder with
hand pressure. Only manufacturing, processing, or otherwise use of asbestos in the friable
form triggers reporting. :
Aluminum oxide (fibrous forms) - The listing for aluminum oxide is qualified by the term
"fibrous forms." Fibrous refers to a man-made form of aluminum oxide that is processed to
produce strands or filaments which can be cut to various lengths depending on the application.
Only manufacturing, processing, or otherwise use of aluminum oxide in the fibrous form
triggers reporting. ,
» Hydrochloric acid and sulfuric acid (acid aerosols including mists, vapors, gas, fog, and
other airborne forms of any particle size) - The qualifier for hydrochloric acid and sulfuric
acid means that only aerosol forms of thiSjChemical are reportable. Aqueous solutions are not
covered by this listing, but airborne forms generated from aqueous solutions are covered.
Nitrate compounds (water dissociable; reportable only when in an aqueous solution) -
The qualifier for the nitrate compounds category limits the reporting to nitrate compounds
that dissociate in water, and thereby generate nitrate ionsJ For the purposes of threshold
determinations, the entire weight of the nitrate compound must be included in all calculations.
For the purposes of reporting releases and other waste management quantities, only the
weight of the nitrate ion should be included in the calculations of these quantities.
WHAT MUST BE REPORTED?
i
If your facility is included in the specified set of SIC codes, has ten or more full-time employees or
the equivalent, and manufactures, processes, or otherwise uses one of the listed Section 313
chemicals in amounts greater than the appropriate thresholds,1 you must report the following

Off-site locations to which you shipped wastes containing the chemical and the quantities of
the chemical sent to those locations;
Information on source reduction activities; and
Treatment methods used for wastes containing the chemical and estimates of their efficiency
for the reportable Section 313 chemical.
A release is defined under EPCRA Section 329(8) as any spilling, leaking, pumping, pouring,
emitting, emptying, discharging, injecting, escaping, leaching, dumping, or disposing into the
environment of any listed Section 313 chemical. The definition of release includes the
abandonment or discarding of barrels, containers, and other closed receptacles. Separate release
estimates must be provided for releases to air, water, and land (e.g., deep well injection, surface
impoundment, permitted landfill).
DOCUMENTING REPORTING EFFORTS
Sound recordkeeping practices are essential for accurate and efficient TRI reporting. EPA
requires that facilities keep a copy of each Form R or Form A report filed for at least three years
from the date of submission (40 CFR §372.10). These reports will also be of use to facilities in
subsequent years when completing future Form R or Form A reports. EPA also requires that

SECTION 3
MAKING THE THRESHOLD DETERMINATION
A separate Toxic Chemical Release Inventory Reporting Form must be submitted for each listed
chemical that is "manufactured," "processed," or "otherwise used" above an activity threshold at
your facility, assuming the SIC code and employee criteria are met. See Table 3-1 for illustrative
examples of these threshold activities.
Table 3-1. Examples of Manufactured, Processed, and Otherwise Used Chemicals
at Coal Mines*
All chemicals that are manufactured during the combustion process are byproducts separate
from the primary product (coal). Because the de minimis exemption does not apply to a
Section 313 chemical manufactured at the facility as a byproduct and does not remain in the
primary product distributed by the facility, metal compounds which were "manufactured during
combustion, are not eligible for the de minimis exemption.
During combustion, if an elemental metal is converted to a metal compound, or if one metal
compound is converted to another metal compound, then a metal compound has been
manufactured, even if it is within the same Section 313 metal compound category. Likewise, if
a metal compound is converted to the Section 313 elemental metal, a Section 313 metal has
been manufactured. The quantity of the Section 313 metal or metal compound manufactured
must be counted towards the 25,000 pound threshold. The question is not whether a metal's
valence state has changed, but whether a new metal or metal compound was created. In these
circumstances, the de minimis exemption does not apply because a Section 313 chemical was
manufactured as a byproduct of the combustion process. Finally, there may be cases in which
the metal compound is not changed at all during combustion. For example, if beryllium oxide in
coal remains as beryllium oxide after combustion, a metal compound has not been
manufactured. In this example, the "otherwise use" of the Section 313 chemical is eligible for
the de minimis exemption.

use activity threshold because the constituents are not incorporated into the product (the
energy produced) and, therefore, the de minimis exemption applies for this activity. Hence,
chemicals present in coal below de minimis levels would not be subject to reporting under the
otherwise use activity.
Activity
As a chemical processing aid
May include conditioners, additives for froth flotation and
thickening/sedimentation, and flocculents for filtration
dewatering.
As a manufacturing aid
May not occur in the coal mining industry.
Ancillary or other use
Combustion of coal, containing Section 313 chemicals
above the de minimis level, for energy production.
Ethylene glycol sprayed on coal to prevent freezing during
transportation of coal from the mine to the beneficiation
plant or for storage at the plant prior to beneficiation.
The use of a listed Section 313 chemical to treat for
destruction another chemical.
The use of EPCRA Section 313 chemicals in support
activities such as cleaning, maintenance, and purification.
* More complete discussions of the industry-specific examples can be found in Section 5 of this guidance document.
CONDUCTING THE THRESHOLD DETERMINATION
An activity threshold determination must
be made individually for each Section 313
chemical by each activity in which the
chemical is manufactured, processed, or
otherwise used at your facility. The
threshold determination is one criterion
used to ascertain whether a Form R or Form A is required to be submitted.
STEP ONE
Identify Section 313 chemicals that are
manufactured, processed or otherwise used.

Coal extraction activities are exempt from reporting, but beneficiation activities are subject to
EPCRA Section 313. Coal beneficiation processes, including crushing and grinding, must be
considered in the threshold determination. In addition, some coal may be combusted to aid in
product coal drying. EPCRA Section 313 chemicals, at above de minimis concentrations, that are
constituents of coal that is combusted are otherwise used and must be considered in making the
threshold determination. However, the combustion of coal may also result in the coincidental
manufacture of other EPCRA Section 313 chemicals. :
Any Section 313 chemicals purchased by
facilities for use as processing or
manufacturing aids or for treating waste
are considered "otherwise used." In
addition, EPCRA Section 313 chemicals in
materials purchased to be used as fuel or
for maintaining equipment operations,
other than for maintaining motor vehicles,
should be included in the threshold ^
determination for "otherwise use"
activities. Any EPCRA Section 313
chemicals in materials purchased to be used in the waste management processes should also be
included in the threshold determination for "otherwise use" activities.
STEP TWO
Identify "processing" and "otherwise use"
activities that are subject to exemptions.
Exclude chemicals associated with these
activities from your threshold
determination.
When performing your threshold determinations, it is important to remember that exemptions
apply to certain facility-related activities. These exemptions were discussed in Section 2 of this
guidance document and may apply only to certain "manufacturing," "processing," or "otherwise
use" activities. For the purposes of an activity threshold analysis, the following areas should be
examined closely to determine whether the TRI Section 313 chemicals subject to certain activities
should be included in the activity threshold and reporting calculations:
Laboratories: Sampling and analysis, research and development (R&D), and QA/QC
activities undertaken in laboratories are exempt if conducted under the supervision of a
technically qualified individual. Pilot plants and support services, such as photo processing,
waste water treatment, and instrument sterilization are not exempt. Wastes generated during
sampling and analysis, R&D, and QA/QC activities in an dn-site laboratory are exempt.
Motor vehicles: Use of products containing Section 313 chemicals for the purpose of most
motor vehicle maintenance activities are exempt, as well as fuel used in those vehicles.

Routine janitorial or facility grounds maintenance: The routine maintenance exemption is
intended to cover janitorial or other custodial or plant grounds maintenance activities using
such substances as bathroom cleaners, or'fertilizers and pesticides used to maintain lawns, in
the same form and concentration commonly distributed to consumers. Equipment
maintenance such as the use of oil or grease is not exempt.
Structural component of the facility: This exemption covers Section 313 chemicals that are
incorporated into the structural components of the facility (e.g., metal in pipes) or that are
used to ensure or improve the structural integrity of a structure (e.g., paint). The facility is
not required to report the releases of Section 313 chemicals that result from "passive"
degradation (degradation or corrosion that occurs naturally in structural components of
facilities).
Materials as they are drawn from the environment or municipal sources- Chemicals
contained in intake water (used for processing or non-contact cooling) or in intake air (used
either as compressed air or for combustion) are exempt from the activity thresholds.
However, EPCRA Section 313 chemicals manufactured from use of the air or water are not
exempt and must be considered for the threshold determination.
In making threshold determinations, it is
important that you keep in mind that a de
minimis exemption applies only to Section
313 chemicals in mixtures or trade name
products manufactured as impurities or
processed or otherwise used in mixtures or
trade name products. This exemption
does not apply to chemicals that are
manufactured as byproducts nor does it
apply to chemicals in wastes that are
processed or otherwise used.
Section 313 chemicals present at less than
1 percent (<10,000 ppm) for chemicals
that do not meet the OSHA carcinogen
standard or less than 0.1 percent (<1,000
ppm) for chemicals that do meet the
OSHA carcinogen standard do not have to
be considered when making your threshold
determinations for processing or otherwise use. Appendix A to this document contains the list of

chemicals are present as impurities below
the de minimis concentration threshold in
manufactured products and eliminate from
further consideration in your manufacturing

Section 313 chemicals subject to reporting, along with the de minimis concentration associated
with the chemical. The list of Section 313 chemicals in the publication Toxic Chemical Release
Inventory Reporting Form R and Instructions for the current reporting year should also be
checked to determine whether the list of chemicals has been updated (e.g., changes in listed
chemicals and chemical categories, and de minimis levels).
The combustion process involves the coincidental manufacturing of Section 313 reportable
chemicals (metals, metal compounds, and formaldehyde), usually as a result of oxidation. Coal
mining facilities should closely examine what metals and metal compounds are manufactured
during combustion. ;
The elemental metals aluminum, vanadium, and zinc (with the qualifier "fume or dust") are
considered manufactured when they are converted from a non-fume or non-dust form to a fume
or dust. This may occur during the combustion of fuel. Notice that this qualifier of fume or dust
applies only to the elemental form of the aluminum, vanadium,: and zinc.
If the Section 313 chemicals were manufactured as a result of the combustion process, determine
if the 25,000 pounds threshold for "manufacturing" activities is met. For threshold determinations
for Section 313 metal compound categories, the entire weight of the metal compound must be
applied towards the threshold, not just the weight of the metal Itself. However, only the quantity
of the parent metal released or otherwise managed is reported on the Form R.
Finally, some waste treatment activities will involve the conversion or reaction of chemicals to
produce a new Section 313 chemical, such as occurs with chemical oxidation or chemical
precipitation. j
Threshold determinations are made based
on the best available information in your
possession. If a facility is aware that a
chemical is probably present in a mixture,
but has no information on its
concentration in the mixture, then they are
not required to consider that chemical in
its threshold determinations. Though, in
general, the following methods should be
employed to determine the appropriate
concentrations to use in threshold
determinations:
STEP FOUR
Gather data needed for calculations of
threshold determination, including:
Inventory Data
Consumption Information
Supplier Notification
Ore Sampling and Analysis Data

If the extract concentration is known (e.g., 33.0% toluene), use it.
If only the upper bound is known (e.g., <5% toluene), use it (e.g., 5% toluene).
If concentration range is known (e.g., 10-30% toluene), then use the midpoint (e.g., 20%
toluene).
If only the lower bound is known, assume the upper bound is 100%. Factor out other known
constituents (e.g., 10% water and >60% toluene), create a range (e.g., 60-90% toluene) and
then use the midpoint (e.g., 75% toluene).
In cases where certain materials that have broad ranges or high upper bounds for multiple
constituents (e.g., %x+%y+%z=l 10% of mixture), the total components of a mixture should not
exceed 100%. In these instances, the best available information should be used to estimate the
approximate concentration of the chemicals in the material. However, if a facility is aware that a
chemical is probably present in a mixture, but has no information on its concentration in the
mixture, then they are not required to consider that chemical in its threshold determinations.
Combustion of coal may result in emissions of hydrochloric acid (HC1) in aerosol form, hydrogen
fluoride (HF), sulfuric acid, chlorine, fluorine and/or formaldehyde. Hydrogen chloride, also
called hydrochloric acid, and sulfuric acid are reportable only in the aerosol form. If aerosol forms
of hydrochloric acid or sulfuric acid are produced during or after combustion and are present in
the flue gas, the amount produced must be applied to the manufacturing threshold. In the absence
of better data, facilities can use the HC1 and HF emission factors, of various types of coal,
presented in Table 3-4. Use the emission factor that corresponds to the type of coal being
combusted. If a facility combusts a mixture of coal types, and knows the mixture ratio, it may
apply this ratio to the emission factors in Table 3-4. Facilities that do not know the type of coal
they use should assume the coal is bituminous or subbituminous, since these types are most
commonly used. The factors in Table 3-4 are more appropriate than AP-42 factors, which are
averages of factors for each type of coal. In the absence of facility-specific information, these
emission factors can be used to estimate threshold values. For guidance on calculating the
amount of sulfuric acid manufactured during combustion, refer to: Emergency Planning and
Community Right-to-Know Act-Section 313: Guidance for Reporting Sulfuric Acid (acid
aerosols including mists, vapors, gas, fog, and other airborne forms of any particle size), EPA,
August 1997.

Calculate the quantity of each chemical
manufactured.] processed and otherwise
used, in pounds, to determine whether the
activity threshold has been exceeded. The
Form R must be completed for each
chemical otherwise used in excess of 10,000
pounds and for each chemical processed in
excess of 25,000 pounds, for each chemical
manufactured in excess of 25,000 pounds.
In determining threshold quantities and
release and other waste management
quantities of Section 313 reportable metals
and metal compounds coincidentally
manufactured from the combustion of coal
or from treatment to remove sulfates and
ash-forming materials, it is not necessary
to measure the change in valence state of
the metals. The question is not whether a
metal's valence state has changed, but
whether a new metal or metal compound
was created. These determinations can be
performed by either estimating or ^ ;
measuring the metal compounds that are
created after the combustion process. Calculations are to be based on readily available data.
These data may include monitoring data collected pursuant to ;other laws and regulations, and, if
no such data exist, then calculations should be based on reasonable estimates. Data on what
occurs to metal constituents in coal during the combustion process suggest that most, if not all
metals, are present as some form of metal compound that does not usually survive combustion.
Therefore, if no data are available which identify specific metal compounds being produced, a
facility may assume that the metals in the coal are converted to the lowest weight metal oxide
possible. This engineering assumption can be used in determining the threshold quantities of all
metals in coal. It is unlikely that using this estimation method; would cause any facility that is not
exceeding thresholds to report because at least some, if not many, of the metal compounds
manufactured as a result of combustion will be heavier than the lowest weight metal oxide.
The best available information should be used to estimate the concentration of the toxic chemical
in the coal. If you have data regarding chemical concentrations in the coal, use this data. If
specific concentration data of Section 313 chemicals in coal are not available, your facility may
use the default values provided in Table 3-2. Table 3-2 lists concentrations of Section 313 metals
typically found in different types of coal. If the facility does riot know which type of coal they
use, the facility should calculate threshold determinations using the high-end concentration values
from Table 3-2. Table 3-3 lists concentrations of metals and metal compounds typically found in
coal and, based on the type of coal with high-end metal concentrations, the quantity of coal one
needs to combust to manufacture 25,000 pounds of the metal compound.
i
To calculate the amount of Section 313 metal compounds manufactured during combustion using
the assumption that metals will be converted to the lowest weight metal oxide possible, facilities
must know the amount of elemental metal in the coal.

The one exception to using metal oxides for determining threshold quantities may be mercury.
Data indicate that most mercury remains volatilized as elemental mercury after combustion rather
than converted to a metal compound. Therefore, the weight of the metal, rather than that of the
metal oxide, can be used in threshold determinations, and this amount then applied towards the
manufacture activity threshold for mercury.
The following example illustrates how to determine the quantities of Section 313 chemicals
manufactured.
Calculating Thresholds for Hydrochloric Acid and Selenium
A facility combusts 1 million short tons of bituminous coal in the reporting year. What quantity of selenium
compounds and HC1 (aerosol) are manufactured?
Selenium Compounds:
Based on the high-end concentration of selenium from Table 3-2, as selenium oxide (SeO,) is 11.2 ug/g coal (see
Table 3-3), or 2.24 x 10* Ibs SeOJton coal
2.24 x 10* Ibs SeOjton coalx 1,000,000 tons of coal = 22,400 pounds ofSeO2 emitted.
Therefore, 22,400 pounds of selenium compounds are manufactured and the 25,000 pound threshold was not
exceeded. Form R reporting for selenium compounds is not required.
Hydrochloric Acid:
The emission factor for HCl for "industrial" external combustion burners is 1.9 Ibslton coal (see Table 3-5).
1.9 IbsHCVton coalx 1,000,000 tons coal = 1,900,000 pounds HCl
Therefore, 1.9 million pounds of HCl are manufactured and the 25,000 pound threshold has been exceeded.
Form R reporting for HCl (aerosol) is required.

SECTION 4
OVERVIEW OF SECTION 313 RELEASE ESTIMATION
This section presents general guidelines for preparing Section 313 release estimates. It begins with
a discussion of general ideas on estimating chemical releases. A section-by-section discussion ,of
release and waste management reporting requirements follows.
GENERAL CONCEPTS
Release Estimation
A Form R or Form A must be completed for each Section 313 chemical that meets the applicable
activity thresholds. Each form requests facility specific information and identifies the chemical for
which thresholds were exceeded. Form A (the abbreviated report) includes a statement that the
facility did not exceed specified amounts while, the main components of Form R are
environmental release estimates to all media for the reportable chemical during the preceding
calendar year. This includes all wastes containing the reportable Section 313 chemical that are
sent off-site from the facility for further waste management. Specifically, facility release estimates
must be made for the following release sources:
Releases to air from fugitive or non-point sources (Section 5.1)
Releases to air from stack or point sources (Section 5.2)
Releases to water directly discharged to a receiving stream (Section 5.3)
Releases in wastes that are injected underground (Section 5.4)
Releases to land on-site (Section 5.5)
Releases to water discharged to a publicly owned treatment works (POTW) (Section 6.1)
Wastes transferred off-site for recycling, energy,recovery, waste treatment, or disposal
(Section 6.2)

TRI FORM R GUIDANCE DOCUMENT
COALMINING
Development of accurate and comprehensive release estimates requires consideration of all
possible release pathways. The threshold determination provides valuable information when
beginning the release estimation process for a Section 313 chemical: each material containing a
Section 313 chemical is identified. For each of these materials, the facility should identify all
potential release sources. A useful way to do this is to draw a process flow diagram that traces
the material's path through the plant. The process flow diagram should identify each major piece
of equipment (including pollution control devices) through which the material passes, from its
initial entry into the facility to its final disposition. The diagram should also identify all potential
release sources and pollution control equipment for the chemical.
i
After you have identified all the potential release sources for a chemical, you can estimate releases
for each source. Often, the starting point for a release estimate is chemical throughput data,
which are typically available from threshold determination calculations.
Given the chemical throughput quantities for a process, you must apply other data and
assumptions to complete the estimates. This information includes process-specific data (e.g.,
scrubber efficiency) and any data developed for other environmentally oriented purposes (e.g., air
and wastewater monitoring data, air and water permits and permit applications, RCRA manifest
data, monitoring data).
Section 313 does not require any new monitoring to be performed. Facilities should use existing
data to calculate release estimates. The accuracy of a release estimate is proportional to the
quantity and quality of the data used in its preparation. Situations may arise where estimates
based on one set of data contradict estimates based on another^ In such cases, the facility should
document the rationale for using one data set (or method) versus another. If a facility is aware
that a chemical is probably present but has no method to estimate releases or quantities on site,
then they are not required to report on that chemical. ,
i
Release estimates can be developed by combining all available data with assumptions concerning
the fate of each chemical in the process. There are four general methods for developing a release
estimate. These methods may be used together or in sequence! in developing release estimates.
Direct measurement (basis of estimate code = M; entered in Part H Sections 5 and 6) -
These are estimates based on actual monitoring of the concentration of a chemical. The
chemical's concentration in the waste stream multiplied by the flow rate or volume of the
waste stream yields the mass of the chemical released. Direct measurement is typically

ensure compliance with applicable environmental regulations. Although this estimation

method should yield the most accurate results, only rarely are sufficient data available for
direct measurement data to be applied without also resorting to other techniques (e.g.,
engineering calculations, mass balance). The frequency of the direct measurements should
be taken into account when determining if monitoring data alone are sufficient for making
a reasonable estimate. For example, if a facility has only gathered monitoring data once
throughout the year, other methods may provide a more accurate estimate.
Note an indication that reportable chemical is below detection is not equivalent to stating
that the chemical is not present. If the reportable Section 313 chemical is known to be
present, a concentration equivalent to half the detection limit should be used in subsequent
calculations of release estimate quantities (i.e., if the limit of detection is 10 mg/1, release
calculations should be performed using a concentration of 5 mg/l). If the reportable
Section 313 chemical is not known to be present in the waste, then 0 percent can be
assumed.
Mass balance (basis of estimate code = C entered in Part II, Sections 5 and 6) - These are
estimates based on a knowledge of the quantity of a chemical entering and leaving a
process. An imaginary boundary is first drawn around the process, and all streams
entering or leaving the boundary are identified. Assuming the amount of the chemical in
the process input streams is known, a facility could calculate the quantity in waste streams
by difference. A facility would need to account for any accumulation or depletion of the
chemical within the mass balance boundary. The equation for mass balance is:
Input + Generation = Output + Amount Reacted + Accumulation
Using a mass balance to estimate a relatively small release of a chemical with a large
throughput can lead to inaccurate, or even negative release estimates. Even a small
percentage error in a large throughput could amount to a greater quantity than the
calculated release. When several large values each with their respective errors are used to
calculate a small release, propagation of errors occurs which could yield a highly
inaccurate value. Other techniques should be considered in these situations.
Mass balance estimates usually require engineering calculations or assumptions to be made
(e.g., all usage results in air or water releases). These assumptions should be explicitly
stated in the documentation and should be checked for reasonableness.
* Emission factors (basis of estimate code = E entered in Part II, Sections 5 and 6) -
Release information derived from facilities or processes similar to yours can be used to
September 26,1997 43

TRI FORM R GUIDANCE DOCUMENT
COAL MINING
estimate releases. Emission factors come in two forms. The first expresses releases as a
ratio of the amount of chemical released to facility throughput or production (e.g., 0.5
pound of Chemical X released per every pound of Material Y used). The second provides
a typical concentration of a chemical in a waste streami (e.g., 0.1 mg/L of Chemical Z in
wastewater from scrubbers). These factors, combined !with process throughput or waste
stream flow data, can be used as a basis for the release estimate. Many emission factors
are available in Compilation of Air Pollutant Emission] Factors (AP-42). AP-42 can be
accessed via the Internet at http ://www.epa. gov/ttn/chief/ap42etc. html. The basis of
estimate code "E" can only be used for published Section 313 chemical-specific emission
factors.
The reliability of emission factors depends on the quality and quantity of data used in then-
derivation, plus the similarity of the process to which they are applied and the quality of
raw materials for the process.
Engineering calculations and assumptions (basis of bstimate code = O entered in Part
II, Sections 5 and 6) - Estimates that do not fall into any of the above categories are
considered engineering calculations. Typically, these estimates are based on standard
engineering principles using properties of the chemicals involved, process data, or process
knowledge. Example chemical properties include vapqr pressure, solubility in water, and
density. Example process parameters include temperature, pressure, and material flow
rate. Other examples of engineering calculations would be the use of general equipment
emissions factors or non-published, facility-developed emissions factors.
Reasonable Estimates: Significant Figures and Use of Range Codes
EPA recommends that two significant figures be used when reporting release and off-site transfer
quantities in Part II, Sections 5 and 6 of Form R. Use of two significant figures may prevent
errors from being reported on Form R, because a small calculating error may not impact the final
reported quantity if the quantity is rounded to two significant figures. If you have reason to
believe that your best estimate of a release quantity is particularly imprecise, you could use one
significant figure or one of the range codes in reporting releases in Part II, Sections 5 and 6 of the
Form R, if applicable: ' ;

TRI FORM R GUIDANCE DOCUMENT COAL MINING
Range Code A = 1 to 10 pounds
Range Code B = 11 to 499 pounds
Range Code C = 500 to 999 pounds
"NA" versus "0"
If you have no releases of a Section 313 chemical to a particular medium, report either "NA," not
applicable, or "0," as appropriate. Report "NA" only when there is no possibility a release could
have occurred to a specific medium or off-site location. If a release to a specific medium or off-
site location could have occurred, but either did not occur or the annual aggre-gate release was
less than 0.5 pounds, report zero. However, if you report zero releases, a basis of estimate must
be provided. If use of the Section 313 chemical began in the reporting year, enter "NA" as the
production ratio or activity index (Part n, Section 8.9 of the Form R).
For example, if nitric acid is involved in the facility's processing activities but the facility
neutralizes the wastes to a pH of 6 or above, then the facility reports a "0" release for the Section
313 chemical. If the facility has no underground injection well, "NA" would be written in Part I,
Section 4.10 and checked in Part n, Section 5.4.1 and 5.4.2 of Form R. Also, if the facility did
not use the Section 313 chemical in the previous year, the facility would have no basis to develop
a production ratio or activity index, "NA" would be checked in Part n, Section 8.9 of Form R.
REPORTING RELEASES IN FORM R, PART H
The following sections discuss the types of release reporting required on the Form R. Releases
must be partitioned into land and air releases and should not be inadvertently "double counted."
For example, a single wastewater discharge should not be listed as both a release to water (on-
site) and a discharge to a POTW (off-site), nor should a release to land be listed as a release to
both knd (on-site) and a transfer to an off-site landfill. Also, subsequent releases from land (such
as a leak from an impoundment) to groundwater is included as a land release in the year the
leakage occurred. No reporting is required past the year in which it occurred. Even if it leaches
out to ground water in the next year.
It is important to note that historical releases are not included in release reporting. For example,
contamination around an underground storage tank (UST) is discovered, but there is no active
leak from the tank. If you know that the contamination occurred during the reporting year (RY),
then report the leak as a release to land. However, if the leak did not occur during the RY, it
should not be included in release reporting.

Finally, the amount of leaks or spills onto pads or containment areas should not automatically be
reported as released to land. The amount should be considered as treated or disposed depending
on type of management activity. After releases to air, amounts cleaned up and disposed of off-
site, amounts recycled, and amounts released to water are considered, then the amount remaining
on the pad is considered to be released to land. Amounts spilled into containment that are directly
reused within the same reporting year without requiring treatment prior to reuse are not subject to
release reporting. ;
Fugitive or Non-Point Emissions (Part H, Section 5.1 of Form R)
Fugitive emissions can occur from almost any part of a facility's operation. Potential sources
include the following:
Normal leakage of valves, pump seals, flanges, connectors, and other devices
Sampling, Packaging, Loading, and unloading of chemicals
Cleaning and maintenance activities such as blowing out pipes
Containers of raw materials, intermediates, or wastes j

TANKS
The TANKS program is designed to estimate emissions
of organic chemicals from several types of storage tanks.
The calculations are performed according to EPA's

contents, the system produces a report which estimates
the chemical emissions for the tank on an annual or
partial year basis. The user can also determine individual
component losses by using one of the specification
options available in the program.
The TANKS program relies on a chemical database of
over 100 organic liquids and a meteorological database
which includes over 250 cities in the United States; users
may add new chemicals and cities to these databases by
providing specific information through system utilities.

the release estimation approach is similar for both types of wastewater discharges, they are
discussed here together. ;
A facility that discharges or has the potential to discharge water containing regulated wastes must
operate under the terms of Federal, State, and/or local permits, such as a NPDES direct discharge
permit, or a POTW indirect discharge agreement. The permit(s) or agreement usually require
measurements of the water volume and monitoring and analyses of some generalized wastewater
parameters including concentrations of various constituents. In some cases, the constituent
analyses required for permit compliance includes Section 313 'chemicals. In these instances,
releases can be calculated by multiplying the volume of wastewater released by the concentration
of the chemical released. Releases discharged to a POTW should be reported as off-site transfers
on Part II, Section 6.1 of Form R.
Based on the concentration and
wastewater flow data available, an
estimate of discharges to water can
be calculated. Facilities should
calculate the daily average
discharges of a reportable Section
313 chemical in pounds and must
use those estimates to determine
the annual discharge in pounds per
year. Using the daily concentration
data available for the reportable
chemical combined with the
wastewater flow data for each of
the sampling dates, calculate an
estimate of pounds per day for
each sampling date. After the
calculations are made for each
monitoring point (e.g., daily,
monthly), the pounds discharged
are averaged to determine an
average daily discharge amount
which would be multiplied by the
number of days discharges were
possible (e.g., 365 days a year).
Example Calculation of Yearly Wastewater
Discharge
A facility has monitoring data on discharges to water of xylene, a
listed Section 313 chemical, and a Form R report is required. In
this example, monitoring data on this chemical are only available
for two days in the year. The daily quantities of pounds of xylene
released for those two dates would then be divided by the number
of sample dates to determine the daily average for the whole
reporting year, which would be used to estimate the annual
discharge of xylene in wastewater:

If no monitoring data exist, NPDES permit applications or POTW agreements may provide
information useful to estimating releases. Otherwise, process knowledge (or in some cases, mass
balance) needs to be utilized to develop an estimate.
Discharges of listed acids may be reported as zero if all discharges have been neutralized to pH 6
or above. If wastewater containing a listed acid is discharged below pH 6, then releases of the
acid must be calculated and reported. For more information on calculating such discharges of
acids, seeEPA's Estimating Releases of Mineral Acid Discharges Using pH Measurements
(EPA745/F-97-003, June 1991).
Underground Injection On-Site (Part n, Section 5.4 of Form R)
A facility that has an underground injection well for waste disposal is regulated by Safe Drinking
Water Act (SDWA) permits. The permit(s) usually require measurements of the waste volume
and analyses of some generalized waste parameters including concentrations of various
constituents. When the constituents for which the permit requires analyses include reportable
Section 313 chemicals, releases via underground injection can be calculated by multiplying the
volume of waste injected by the concentration of the chemical in the waste. Facilities must report
amounts of Section 313 chemicals injected into Class I wells (Part II, Section 5.4.1 of Form R)
and amounts injected into Class II-V (Part II, Section 5.4.2 of Form R).
Release to Land On-Site (Part n, Section 5.5 of Form R)
In most circumstances involving the disposal of many Section 313 chemicals, land disposal is
regulated by RCRA and state regulations. In part n, Section 5.5, TRI is concerned with the total
amount of the specified reportable Section 313 chemical released to land, regardless of the
potential for the chemical to leach from the disposed waste.

Estimating Releases for Accidental Losses
On-site disposal includes disposal in an on-
site RCRA Subtitle C landfill (Part E,
Section 5.5.1 A of Form R), disposal in
other on-site landfills (Part n, Section
5.5. IB of Form R), disposal in a land
treatment/application farming unit (Part n,
Section 5.5.2 of Form R), and disposal in a
surface impoundment (Part n, Section
5.5.3 of Form R). Data concerning these
types of "intentional" on-site disposal are
usually readily available because facilities
are required to monitor the quantity of
waste and will have a waste profile that
describes typical concentration ranges for
waste constituents. In some cases,
concentrations of constituents in the waste
have been measured. If on-site waste
treatment occurs prior to on-site land
disposal, the treatment efficiency and a
mass balance can be conducted to
determine the quantity of a chemical that is
land disposed. For example, a facility can
determine the amount of the chemical
present in the untreated waste, determine
the efficiency of treatment in removing or
destroying the chemical in the waste,
account for other releases (i.e., fugitive
emissions, leaks, spills, accidental releases,
losses to air pollution control devices,
etc.), and determine that the remainder is
the quantity of the chemical land disposed.
Releases to land on-site/other disposal
(Part II, Section 5.5.4 of Form R) include
the amount of chemical released to land on
site not covered by any of the above
categories. Releases to land on-site/other
disposal includes spills, leaks, or
"unintentional" disposal, such as metal dust that is deposited onto soil. Incident logs or spill
reports can provide useful information.
Leaks, spills, and drips from the loading and transfer of
chemicals received at the facility should be considered
and reported in your release estimates. Data concerning
specific incidents (such as notification reports or incident
logs) should be used to estimate releases. Equations
found in Section 6 of EPA's Estimating Releases and
Waste Treatment. Efficiencies for the Toxic Chemical
Release Inventory Form (EPA 560/4-88-002, December
1987), provides guidance on calculating releases from
chemical spills or leaks, including liquid discharges,
fraction of discharge flashed, vaporization, two-phase
discharges, and gas discharges.
EXAMPLE: A facility uses more than 10,000 pounds of
ethylene glycol during the year to prevent freezing of coal
piles. While unloading on a windless overcast day, a
malfunction occurs and onsite personnel visually estimate
that 50 gallons of ethylene glycol are spilled. Most of the
spill remains on the pad, however, an estimated ten
percent flows off. the pad and onto the soil. Absorbent
material used to remove the ethylene glycol from the
concrete pad is transferred offsite for disposal. How
would these releases be reported on the Form R? The
density of ethylene glycol is 9.3 pounds per gallon, and
the vapor pressure is 0.06 mm Hg at 68° F.
Quantity spilled == 50 gal x 9.3 IbsJgal = 465 Ibs.
Amount spilled onto pad = 465 x90% = 418.5 Ibs.
Amount spilled onto soil = 465 x 10% - 46.6 Ibs.
Air emissions of ethylene glycol are expected to be
negligible due to the low vapor pressure and
environmental conditions, provided response and cleanup
are immediate. Therefore, the total amount spilled onto
the concrete pad (418.5 pounds) is transferred offsite and
should be reported in Sections 6.2, and the total amount
spilled onto the soil (46.6 pounds) should be reported in
Section 5.5.4, other disposal.

Transfers in Wastes to Other Off-site Locations (Part n, Section 6.2 of Form R)
Similar to on-site disposal, data concerning off-site waste transfers are usually readily available
because facilities are required to monitor the quantity of waste and either measure concentrations
of chemicals or develop a waste profile that describes typical concentration ranges. Under
Section 313, off-site transfer estimates are based on the final, known disposition of the reportable
Section 313 chemical in the waste sent off-site for further waste management. For example, a
reportable Section 313 metal is contained in a waste solvent sent off-site for energy recovery
purposes. Even though the waste stream as a whole has a sufficient heat value to warrant energy
recovery, metals do not have a significant heat value and, therefore, cannot be combusted for
energy recovery. Unless the facility had additional information on the fate of the reportable
Section 313 metal in this waste, the facility must assume the metal is being disposed and should
report the quantity sent off-site accordingly in Part n, Sections 6.2 and 8.1 of Form R.
Even wastes that were minimally processed, such as wastes that were repackaged, such as small
containers removed from a lab pack that were not otherwise opened or managed, may need to be
reported if the article exemption (as discussed in Section 2) is not applicable.
On-site Waste Treatment Methods and Efficiency (Part n, Section 7 A of Form R)
In Section 7A, the following information must be reported:
General waste stream types containing the Section 313 chemical being reported;
Waste treatment methods or sequence used on all waste streams containing the Section
313 chemical;
Range of concentration of the Section 313 chemical in the influent at the first step in a
waste treatment system;
Efficiency of the waste treatment method or sequence in destroying or removing the
Section 313 chemical; and
Indication of whether the efficiency estimate was based on actual operating data.
Report any waste treatment step through which the reportable Section 313 chemical passes
regardless of treatment efficiency. Report all non-identical parallel steps and all sequential steps.
Waste treatment for the purpose of Section 7 A is defined as removal of the Section 313 chemical
from the waste through destruction, biological degradation, chemical conversion, or physical

removal. Note that this definition of waste treatment is broader than the definition used in Part II,
Section 8 of Form R (discussed later). Section 7A treatment efficiency is calculated as follows:
percent efficiency = (input - output) x 100%
input :
i
If your facility has a measurement of the pollutant concentration of input and output at the
treatment unit, these data should be used to calculate the treatment efficiency. If these
measurements are not available, data from literature or the equipment manufacturer can be used
for estimation purposes. Equipment manufacturer data on treatment efficiencies often represent
ideal operating conditions with an ideal waste matrix. Thus, you may want to adjust such data to
account for downtime, process upsets, and other less than optimum conditions during the year

CALCULATING RELEASE ESTIMATIONS AT COAL MINING FACILITIES
In section 4, the tools and techniques available for estimating releases to the environment and
reporting of the disposition of wastes (including off-site transfer, land disposal, underground
injection, and wastewater discharges) were discussed. In this section, typical beneficiation
processes utilized by coal mines, such as size reduction, screening/classification, cleaning, and
dewatering, are discussed. Coal mining facilities should evaluate their technologies on a site-
specific basis. This guidance is merely a starting point for considering possible releases and
estimation methods. Developing accurate and comprehensive release estimates requires the
consideration of all possible release pathways.
The following discussions presume that threshold determinations reveal the need to complete a
Form R report for one or more Section 313 chemicals.
EXTRACTION
Coal extraction involves accessing and removing ore deposits from the ground. Raw coal is
generally obtained by surface, strip, or underground mining. During surface or strip mining the
overburden, defined as the "unconsolidated material that overlies a deposit of useful materials or
ores" (40 CFR §372.3), is removed to expose the coal deposits; underground mining involves
creating a series of shafts and corridors to access the coal seam. Coal mining extraction
processes, and therefore the overburden, are exempt from the EPCRA Section 313 reporting
requirements; however, coal transport and beneficiation activities are subject to EPCRA Section
313 reporting, with the exception of applying the motor vehicle exemption to earth-moving
vehicles. '.

Although coal beneficiation plants are generally at or near coal mines, the coal still must be
transported a distance from the mine to the plant either by truck, rail, or conveyer belt depending
on distance and terrain. In addition, clean coal must be transported from the site after
beneficiation. When dry mining processes are involved, particulate matter may be released from
transportation through wind removal. However, this possibility is low because a large portion of
coal mines employ wet processes, thus reducing the potential for blowing during transport.
Depending on regional weather conditions, ethylene glycol or calcium chloride may be sprayed on
coal to prevent freezing in transport and storage. Air emissions from the application of these
chemicals are possible due to overspray or volatilization. Facilities should also be aware that
when storing in land-based coal piles, dripping and over spray releases may occur to the land.
Releases on-site to air, water, or land as a result of spraying activity are reportable.

Coal beneficiation, or preparation, includes all the methods utilized to upgrade or clean the raw
coal in order to improve the energy value and to remove non-coal impurities. Beneficiation
encompasses several different processes. The four main stages are: size reduction, screening/
classification, coal/impurity removal (cleaning), and dewatering/drying. Fine coal conditioning
with sulfuric acid may manufacture the aerosol form of the acid. For guidance on estimating
releases for sulfuric acid aerbsol, refer to Emergency Planning and Community Right-to-Know
Act-Section 313: Guidance for Reporting Sulfuric Acid (acid aerosols including mists, vapors,
gas, fog, and other airborne forms of any panicle size), EPA,; August 1997. The cleaning and
dewatering processes are different depending on the coal particle sizes. Not all plants conduct all
the processes. Some plants may only size and classify the coal while others may undertake all
four stages. Figure 5-1 presents a process flow diagram for coarse and intermediate grade coal.
Figure 5-2 presents a process flow diagram for fine-grade coal At the plant, the coal is cleaned of
several types of impurities, including sulfur compounds and ash-forming elements. The sulfur
content in the run-of-mine coal can be in three forms: pyritic sulfur, sulfates, and organic sulfur.
In the US, the total sulfur in coal is generally high but varies from 1-4 percent. Eastern
(Appalachian) coal has a higher percentage of sulfur than western coal. The pyrite and sulfates
can be removed through physical cleaning, but the organic sulfur can only be removed with
chemical or biological cleaning. As of 1993, organic sulfur removal had only taken place on the
demonstration level. Therefore, the amount of organic sulfur sets the lowest limit as to the
amount of physical cleaning that can be carried out. Ash-forming elements are associated with a
large portion of the Section 313 chemical releases in coal. Aluminum, arsenic, calcium,
chromium, lead and iron are only a few of these elements found in coal. Facilities should be
aware that releases will vary depending on the estimated starting concentration of impurities and
on the chosen cleaning techniques. Fugitive particulate matter (PM) (e.g., coal dust from
roadways, stock piles, refuse areas, railroad cars, conveyor belt pouroffs, crushers and classifiers)
should be considered when estimating releases.

TRI FORM RGUIDANCE DOCUMENT COALMINING
Size Reduction
The run-of-mine coal must be crushed, ground and/or broken in order to prepare the coal for the
washing process. Some size reduction occurs inside mines during extraction and is exempt from
EPCRA Section 313 reporting. Size reduction allows the plant to handle the coal more easily
while at the same time helps to remove impurities by breaking the coal down into smaller pieces.
This process is performed using large machines, such as rotary brokers and rollers. These
operations are conducted either in the open or in enclosed structures. Size reduction usually
occurs as a wet process because the run-of-mine coal is either received wet from the mine or is
slurried at this time. No Section 313 chemicals are added at this point. The possibility of air
releases is very low when the coal is processed wet because it suppresses dust, thereby reducing
the possibility of PM emissions. Another technique for reducing emissions during loading,
crushing and screening involves enclosing the process, area and circulating air through fabric
filters. With these control techniques, some low level emissions of natural coal constituents may
still occur but they will be less in magnitude than those occurring at facilities without these
measures. Some Section 313 metals found in coal include aluminum, arsenic, barium, chromium,
lead, manganese, selenium, and vanadium.
Screening/Classification
Following size reduction, the raw coal is screened or classified. Screening is performed to match
size specifications of cleaning equipment and also to meet market demand. Generally the coal is
divided into three groups; coarse (>10 mm), intermediate (0.6-10 mm) and fine (<0.6 mm). Some
plants, however, only make coarse and fine distinctions. Classification mechanisms used include
screening through a mesh of perforated plates or metal wires/rods of fixed aperture. These
processes can be carried out in open or enclosed structures and either wet or dry. The coal is
now ready to be cleaned in house or transported to another facility. Again, no Section 313
chemicals are added at this stage. Any releases would be low, if not negligible, because a majority
of the preparation plants utilize wet screening processes. However, special attention should be
paid to any particulate matter emissions of the ash-forming elements mentioned above.

Coal Cleaning
At this stage, the coal is cleaned and impurities, such as sulfur and ash-forming elements, must be
removed. Two primary techniques are used: (1) gravity concentration or separation, and (2)
flotation. The equipment used is determined based on coal particle size. Gravity concentration
and dense medium separation typically are used for coarse and intermediate coal, while flotation is
used exclusively for fine coal. Special attention should be given to fine coal treatment because of
its reliance on chemical additives. ]
i
Course/Intermediate Coal Cleaning
\
There are two types of gravity methods (coal washing) performed on intermediate and coarse
coal, gravity concentration and dense medium separation. Gravity methods rely on differences in
specific gravities between the coal and the refuse minerals. ;
i
i
Gravity Concentration
\
Gravity concentration methods used to clean coal include jigs, cyclones, shaking tables, and
Reichert cones. A significant portion of coal preparation plants use jigs to separate coal from
non-coal material. The majority of jigs process wet coal, but some pneumatic jigs are used and
emissions of particulate matter should be evaluated to determine if releases of Section 313
chemicals are occurring. Like jigs, the shaking tables, cyclones, and Reichert cones rely on water
flow and motion of the equipment to separate more dense impurities from the lighter coal. Any
emissions are generally low because much of the coarse separation occurs as a wet process.
1 r
Dense Medium Separation (DMS) \
Another commonly used gravity method is dense medium separation. This process usually occurs
in a large, open tank, and pulverized magnetite in water is the preferred medium in industrial coal
separation. The density of the medium is adjusted to lie between the dense inorganic matter and
the less dense organic, combustible fraction of coal. As a result, the inorganic material sinks to
the bottom of the tank and the organic coal floats to the top of the tank where it is skimmed from
the tank. However, reportable releases should not be significant unless other chemicals were
added to the medium to adjust its density.

TRI FORM R GUIDANCE DOCUMENT COAL MINING
Fine (Advanced) Coal Cleaning
Fine coal cleaning involves chemical conditioning of the coal followed by flotation to recover
clean coal. These steps remove the inorganics.
Conditioning
Depending on the characteristics of the coal, some of the chemicals used include lime, sodium
carbonate, sodium hydroxide, and sulfuric acid. Only aerosol forms of sulfuric acid must be
reported. Conditioners and regulators adjust pH, so as to facilitate the flotation process. There
are many advanced cleaning techniques. Only froth flotation, however, has been proven effective
at the industrial level Many other treatments show promise but as of yet have been performed
only on the demonstration level.
Froth Flotation
Froth flotation is the most widely used method of flotation in coal preparation facilities. Flotation
typically will be conducted using air, water, the coal slurry, and flotation agents (e.g., collectors,
activators, depressants, dispersants, or flocculents) specially selected to recover the desired fine
coal. Collectors (promoters), such as fuel oil and kerosene, cause adherence between the fine
coal particles and the air bubbles. Table 5-1 shows the chemical constituents in commonly used
collecting agents. Depressants, including amyl xanthate, are used to depress or cause the
inorganic impurities to sink to the bottom of the tank. Activators promote flotation in the
presence of collecting agents. Methyl isobutyl carbitol and even pine oil are common frothers that
stabilize air bubbles by reducing surface tension, thus allowing froth formation. During froth
flotation, the coal-water slurry is passed through a series of "rougher" and "cleaner" cells that are
spragged with air from below. Particles in this slurry are preferentially wetted by various agents
causing the hydrophobic coal particles to adhere to the surfaces of air bubbles. As the air bubbles
rise to the surface, the coal slimes are transported to the surface and are removed by skimming
with a mechanical scraper. This step could generate fugitive air emissions along with releases in
wastewater.

Note: If specific concentration data of Section 313 chemicals in the collecting agents are not available, your facility may
use the default values provided in Table 5-1 to estimate concentration values of constituents.
Each facility must review its own process to identify all reagents used in flotation and thickening.
Current MSDSs provided by the supplier should identify Section 313 chemicals present in the
flotation agents and the concentrations of the chemicals. If an activity threshold is exceeded for
any Section 313 chemical in a flotation agent (e.g., 10,000 pbunds or more of the Section 313
chemical are otherwise used on a facility-wide basis), a Form R is required for that chemical and
releases must be estimated.
i
After the flotation, tailings (in a wastewater slurry) may be sent to a thickener. The thickener
process may also use chemicals to accelerate settling and agglomeration. Some of these
chemicals are disposed of either along with the tailings or separately. Water from the thickeners is
recycled to the mill. The tailings are generally sent to a tailings impoundment. As the solids settle,
decanted water is reclaimed. Reportable Section 313 chemicals contained in any discharges to
surface water would be reported as a discharge to a receiving stream or water body (Part n,
Section 5.3 of Form R). Even those facilities subject to "zero discharge" requirements of 40 CFR
September 26, 1997

-------
TRI FORM R GUIDANCE DOCUMENT COAL MINING
Part 440, Subpart J may have authorized discharges due to the storm exemption or from overly
contaminated process solutions, and these would be reportable as well. Similarly, the reportable
Section 313 chemicals contained in the tailings disposed in the impoundment (less the quantity
discharged from the impoundment) should be reported as a release to land on-site: surface
impoundment (Part n, Section 5.5.3 of Form R). In addition, there is inevitably some seepage
from the impoundment during settling. Information on the facility's water balance and
composition of its tailings water, solids, and discharge can be used to calculate estimates of
reportable releases.
The 1982 Final Effluent Guidelines document for coal mining summarized a study to determine
the presence and concentration of the 129 toxic or "priority" pollutants in the coal mining point
source. Both raw wastewater and final effluent wastewater were sampled at seven sites. Of the
pollutants identified as possible additives to froth flotation, benzene, ethylbenzene, naphthalene,
and toluene were found in the preparatory plant wastewater; benzene and toluene were found in
the "associated areas." Many of the following metals were present in all wastewater sampled:
antimony, arsenic, beryllium, cadmium, chromium, copper, iron, lead, manganese, mercury,
nickel, selenium, silver, thallium, and zinc. The organics in the wastewater may have originated
from treatment of the fine coal during froth flotation. The metals could potentially enter the
wastewater as runoff from coal piles, any of the rinsing steps, tank wastewater from froth
flotation or sedimentation, and dewatering.
Dewatering and Drying
The purpose of dewatering and drying is to remove excess moisture and prepare the cleaned coal
for shipment. All cleaning operations utilizing water require some type of mechanical or thermal
drying. Figure 5-3 presents a process flow diagram for thermal dewatering using a coal-fired
furnace. Fuels used for thermal drying are considered to be otherwise used. Usually, the more
coarse coal does not undergo as extensive drying as the fines. More advanced techniques,
including thermal drying, must be utilized with fines because they possess a greater surface area to
volume ratio then more coarse coal. Once the clean coal is dewatered, the wastewater is either
recycled on-site or sent to a POTW. Facilities should be aware that Section 313 chemicals are
reportable when released to a POTW or receiving stream. Calculations will differ because each
water treatment system is site specific. Below, some common dewatering techniques will be
discussed.

Course and Intermediate Dewatering :
Coarser coal is predominantly dewatered using mechanical methods including drying screens, and
centrifuge dewatering. Generally, no Section 313 chemicals are added. However, particulate
matter releases may occur while the coal is drying.
Fine Dewatering .,
Several techniques are available to accomplish fine coal dewatering such as vacuum filtration and
thermal dewatering. ;
Vacuum Filtration Dewatering
Vacuum filtration is used for dewatering of the cleaned fines and of the tailings. Tailings
dewatering is preceded by thickening (as discussed earlier). FJocculents are frequently used as
filter aids. Section 313 chemicals are reportable when released in wastewater to a POTW or
receiving stream. These releases should be estimated based on monitoring data or best engineering
judgement and be reported as a release to receiving streams or water bodies (Part n, Section 5.3
of Form R) or as a discharge to a POTW (Part H, Section 6.1 of Form R).
i
Thermal Dewatering , !
At this stage, the fine coal has been cleaned using froth flotation and usually vacuum filtration
dewatering has occurred. Due to the large surface area of the small particles, further dewatering
is needed. Thermal drying or dewatering is especially successful at drying fine particles.
Generally, coal preparation plants reserve thermal dewatering as the final step for drying fine coal.
This process involves combustion of coal in furnaces to sufficiently dry the wet coal to marketable
levels. The coal used in thermal dewatering is considered to be otherwise used. If thermal
dewatering is utilized, elaborate dust collection is required and the facility must be aware of all the
wastes generated from coal combustion. The remainder of this section covers potential releases in
detail.

Fly and Bottom Ash
Coal combustion generates considerable amounts of both bottom ash and fly ash. Bottom ash is
unburned matter that collects at the bottom of the boiler, and is present mainly at facilities
combusting coal. Fly ash is a fine, light ash borne in flue gas, collected by mechanical ash
collectors and particulate control devices such as electrostatic precipitators, baghouses, or
wetscrubbers. Cyclones are used to gather particulate matter from combustion. Fly ash is
produced at preparation plants during coal combustion. :
Because the de minimis exemption does not apply to a Section 313 chemical manufactured at the
facility that does not remain in a product distributed by the facility as an impurity, metal
compounds in ash which were manufactured during combustion are not subject to the de minimis
exemption. If the manufacturing threshold for a Section 313 compound category is met or
exceeded, then all releases must be reported on Form R, regardless of concentration. However,
only the weight of the EPCRA Section 313 metal itself, not the weight of the entire metal
compound, is used to report quantities released and transferred off-site for waste management.
In the absence of facility-specific data, typical concentrations of metals in ash byproducts from the
combustion of coal presented in Table 5-2 can be used as a basis for estimating quantities released
during coal combustion.
Applicable codes for treatment of ash are P13 (Sludge Dewatering), Pll (Settling/Clarification),
F83 (Thermal Drying/Dewatering) (Part H, Section 7A). The quantity of a Section 313 chemical,
except for metals or metal compounds, destroyed or chemically converted would be reported in
Part II, Section 8.6, Quantity treated on-site, of Form R, Section 313 metals cannot be reported

section. The facility should consider amounts of metals managed as waste and potentially
distributed in product as a mass balance compared to amounts of the metal originally contained in
fuels used.
Air Emissions from Combustion
The combustion of coal may result in the volatilization of various Section 313 chemicals which
become part of the flue gas. Amounts of these chemicals not caught in particulate control devices
may result in stack emissions of arsenic, beryllium, cadmium, chromium, formaldehyde, lead,
manganese, mercury, nickel, methanol, polycyclic aromatics (such as naphthalene), and other
Section 313 chemicals. To calculate the amount of metals emitted to the air, only the weight of
the parent metal must be considered. Section 313 chemicals which form during combustion are
considered "manufactured" and releases of these chemicals are not subject to the de minimis
exemption. Combustion of coal may also result in emissions of hydrogen chloride (HC1),
hydrogen fluoride (HF), chlorine, and fluorine. Hydrogen chloride, also called hydrochloric acid,
is only reportable in aerosol form. If aerosol forms of hydrochloric acid are produced during or
after combustion and are present in the flue gas, the amount produced must be applied to the
manufacturing threshold.
Releases of Section 313 chemicals to the air may be calculated using information from monitoring
data, air permits, and air permit applications. Emissions information from equipment vendors,
particularly emission performance guarantees or actual test data from similar equipment is another
potential source of information for release
calculations.
In the absence of facility-specific data, emission
factors can be used to estimate emissions of
Section 313 chemicals. AP-42 emission for
metals and organic compounds are given in
Tables 5-2, and 5-3 respectively. These tables
are specific to certain conditions (e.g., fuel
type). To estimate releases of HC1 and HF when
no better data are available, assume the amount
released is the amount manufactured (calculated
using the factors presented in Table 3-4, in
Section 3 of this document) minus amounts
removed by air control devices. Emission
estimates will vary, depending on the efficiency
Use of Emission Factors
The general equation for emission estimation is:
E = AxEFx(l-ER/100)
where:
E = emissions,
A = activity rate,
EF = emission factor, and
ER= overall emission reduction efficiency, %.
ER is further defined as the product of the control device
destruction or removal efficiency and the capture
efficiency of the control system. When estimating
emissions for a long time period (e. g., one year), both
the device and the capture efficiency terms should
account for upset periods as well as routine operations.

dust control devices. Therefore, the fugitive particulate matter emissions from these systems are
anticipated to be minimal.
Fugitive emissions and stack emissions are reported in Sections 5.1 and 5.2, respectively, in Part
n of Form R.
Emission Factor Ratings for Tables 5-3 and 5-5 are as follows:
A Excellent. Factor is developed from A- and B-rated source test data taken from many
randomly chosen facilities in the industry population. The source category population is
sufficiently specific to minimize variability.
B Above average. Factor is developed from A- or B-rated test data from a "reasonable number"
of facilities. Although no specific bias is evident, it is not clear if the facilities tested represent a
random sample of the industry. As with an A rating, the source category population is sufficiently
specific to minimize variability.
C Average. Factor is developed from A-, B-, and/or C-rated test data from a reasonable number
of facilities. Although no specific bias is evident, it is not clear if the facilities tested represent a
random sample of the industry. As with the A rating, the source category population is
sufficiently specific to minimize variability.
D Below average. Factor is developed from A-, B- and/or C-rated test data from a small
number of facilities, and there may be reason to suspect that these facilities do not represent a
random sample of the industry. There also may be evidence of variability within the source
population.
B Poor. Factor is developed from C- and D-rated test data, and there may be reason to suspect
that the facilities tested do not represent a random sample of the industry. There also may be
evidence of variability within the source category population.
