1 IDENTIFICATION OF THE INFORMATION COLLECTION

1(a) Title of the Information Collection

TITLE: Toxics Release Inventory (TRI) Form R and Form A Toxic 

Chemical Release Reporting, Recordkeeping, Supplier 

Notification and Petitions under Section 313 of the Emergency 

Planning and Community Right-to-Know Act

EPA ICR No.: 1363.23

OMB Control No.: XXXX

1(b) Short Characterization/Abstract

This Information Collection Request (ICR) is for the information collection requirements 

associated with EPA’s Toxics Release Inventory (TRI) Program. Pursuant to section 313 of 

EPCRA, certain facilities that manufacture, process, or otherwise use specified toxic chemicals in 

amounts above reporting threshold levels must submit annually to EPA and to their designated 

State or Indian Country officials toxic chemical release forms containing information specified by 

EPA, 42 U.S.C. 11023. In addition, pursuant to section 6607 of the Pollution Prevention Act 

(PPA), facilities reporting under section 313 of EPCRA must also report pollution prevention and 

waste management data, including recycling information, for such chemicals. 42 U.S.C. 13106. 

EPA compiles and stores these reports in a publicly accessible database known as the Toxics 

Release Inventory (TRI).

1

Currently, facilities subject to the TRI reporting requirements may use either the EPA Toxics 

Release Inventory Form R (EPA Form #9350-1), or, if they meet alternate threshold requirements, 

the EPA Toxics Release Inventory Form A Certification Statement2(simply referred to as “Form 

A” - EPA Form #9350-2). With Form R, a facility reports one chemical per form; with Form A, a 

facility may report multiple chemicals per form.3

In the last ICR Renewal, EPA transitioned from issuing two separate ICRs to issuing a single 

ICR—EPA ICR No. 1363.21, OMB Control No. 2025-0009 that encompasses both Form R and 

Form A. In this Renewal, EPA proposes revisions to the Form R and Form A to clarify data 

 

1 Certain sectors are subject to TRI reporting. For a complete listing of the North American Industry Classification 

System (NAICS) codes subject to TRI reporting see Appendix E of this ICR Supporting Statement.

2 The Form A submission requires a Certification Statement confirming that the sum of amounts of the chemical in 

releases and waste does not exceed the appropriate release and waste annual reportable amounts for that reporting year

(see Form A in Appendix A for Certification Statement details).

elements and enhance data utility. Specifically, EPA proposes to make the following changes to 

the forms:4

 Add an optional extension to all phone numbers to allow facility representatives to provide 

the extension needed for a direct connection.

 Add an optional field to allow facilities to indicate the section of the water body that 

received the surface water discharges reported in Section 5.3. Specifically, facilities will be 

able to provide “reach codes,” which are unique codes that identify a continuous piece of 

surface water with similar hydrologic characteristics. 

 Move the header “5.5 Disposal to land on-site” to precede Sections 5.4 and 5.5 on Form R 

so that it covers both 5.4 and 5.5. Re-word 5.4.1 and 5.4.2 to fit under the new header as 

follows: Section 5.4-5.5: Disposal to land on-site, Section 5.4.1: Class 1 Underground 

Injection Wells, Section 5.4.2 Class II-V Underground Injection Wells. The remaining 

sections of Section 5.5 are unchanged.

 Provide the heading, “Production-related waste managed” for Sections 8.1-8.7 and re-label 

Section 8.8 “Non-production-related waste managed.” 

 Add checkboxes to indicate whether facilities have provided a “Production Ratio” or 

“Activity Ratio” in Section 8.9.

 Add a new column (d) in Section 8.10 where facilities have the option to provide a 

percentage range indicating the estimated annual reduction in chemical waste generation 

associated with a given source reduction activity.

 Provide optional barrier codes in Section 8.11 that facilities have the option to use to 

indicate why they could not implement any source reduction activities during the reporting 

year. 

 Allow facilities to categorize optional free-text information entered in Sections 8.11 and 

9.1 by selecting from a list of topics provided in TRI-MEweb.

Pursuant to EPCRA §313 (and PPA §6607 because of its linkage to EPCRA), EPA's Office of 

Environmental Information (OEI) collects, processes, and makes available to the public all of the 

information collected. EPA stores the information gathered under these authorities in a database 

available through the Internet. EPA, other federal, state, and local government agencies; industry; 

and the public use TRI extensively. Program offices within EPA and other government agencies 

have used TRI, along with other sources of data, to establish priorities, evaluate potential exposure 

scenarios, and conduct enforcement activities. Industries use TRI data to identify pollution 

prevention opportunities and set goals for emissions reductions. Environmental and public interest 

groups use TRI data to make the public more aware of releases of chemicals in their communities, 

as well as to initiate direct negotiation and risk reduction with facilities.

EPA developed EPA Information Quality Guidelines to ensure the utility, objectivity, and integrity 

of information that the Agency disseminates. The information supporting this ICR aligns with all 

appropriate EPA policies, including EPA's Information Quality Guidelines. In particular, the EPA 

Agency-wide quality system helps ensure that EPA organizations maximize the quality of 

information disseminated by the Agency. The quality system is documented in EPA Order 5360.1

A2, Policy and Program Requirements for the Mandatory Agency-wide Quality System and the 

EPA CIO Policy 2106.0 US Environmental Policy: Quality Policy Oct 2008. 

An updated Procedure for Quality Policy was published in October 2008.5The information 

supporting this action is also consistent with EPA's Guide to Writing Information Collection 

Requests Under the Paperwork Reduction Act of 1995, revised November 2005. It is EPA's 

intention that collection of information under this ICR will result in information that will be 

collected, maintained, and used in ways consistent with both EPA's Information Quality 

Guidelines and the OMB Information Quality Guidelines.6

The TRI data are unique in providing a multi-media (air, water, and land) picture of toxic 

chemical releases, transfers, and other waste management activities by covered facilities on a 

yearly basis. With a centralized database and electronic data access tools, TRI provides a wide 

range of capabilities for a variety of users. Communities and governments can access the 

identities and quantities of listed toxic chemicals that many industrial facilities in their area 

release, transfer, or otherwise manage as waste. In addition, industries can use TRI as a tool for 

evaluating progress on their pollution prevention goals.

OMB last approved a combined Form R/Form A ICR on October 14, 2011, with an expiration 

date of October 31, 2014. The ICR approved at that time reflected a total program reporting 

burden projection of 73,727 responses, 3.52 million hours and $174.5 million for Form R and 

Form A respondents. For this ICR Renewal, EPA projects total responses, burden, and cost of 

Form R and Form A reporting at 74,869 responses, 3.56 million hours and $183.4 million. This 

slight increase is due to rulemakings since the last OMB approval (see Figure 2 on p. 40 for TRI 

Rulemaking and ICR Chronology). Further, the TRI program proposes to revise data elements 

for the reporting forms, though these proposed revisions should have a negligible impact on form 

burden.

This ICR estimates an average of 35.71 hours per Form R (including all proposed form changes) 

to complete all activities associated with Form R completion (rule familiarization, reporter 

compliance determination, calculations, form completion, and recordkeeping). By comparison, 

EPA estimates an average 21.96 hours for facilities submitting a Form A for a single listed 

chemical (all estimates incorporate proposed changes).7Thus, for a facility filing a Form A 

instead of Form R for a single listed chemical, according to EPA’s TRI burden methodology, the 

alternate threshold yields an average savings of 13.7 hours per chemical.

6 The Office of Management and Budget publishes these guidelines in accordance with the Guidelines for Ensuring 

and Maximizing the Quality, Objectivity, Utility, and Integrity of Information Disseminated by Federal Agencies 

(Government-wide Guidelines) published in interim final form by OMB in the Federal Register in Volume 66, No. 

189 at 49718 on September 28, 2001, and updated in final form in Volume 2, No. 67 at 8452 on February 22, 2002.

7 Actual Form R burden is estimated at 35.70516, which reflects the nominal Form R burden as developed in EPA’s 

Ratio Based Burden Methodology (RBBM, see Section 6 for a discussion of this methodology), with updates for 

subsequent rulemakings (dioxin) affecting unit reporting burden. Similarly, actual Form A burden is estimated at 

21.95867.

2 NEED FOR AND USE OF THE COLLECTION

2(a) Need/Authority for the Collection

This information collection activity is a statutory requirement pursuant to EPCRA §313 

(42 U.S.C. 11001 et seq.) and PPA §6607 (42 U.S.C. 11071 to 11079). According to EPCRA 

§313(h), the purpose of the data collected by the forms is to "inform persons about releases of 

toxic chemicals to the environment; to assist governmental agencies, researchers, and other 

persons in the conduct of research and data gathering; to aid in the development of appropriate 

regulations, guidelines, and standards; and for other similar purposes."

Section 6602 of the PPA establishes a national policy to prevent or reduce pollution at the source 

whenever feasible. To further this goal, EPA collects and disseminates information intended to 

fulfill that responsibility in part and to provide a basis for measuring progress in pollution 

prevention.

EPA’s regulations implementing TRI reporting are codified at 40 CFR part 372. Each covered 

facility must report on each listed chemical manufactured, processed or otherwise used in excess 

of the reporting thresholds established in EPCRA §313(f)(1). 

EPA established an alternate threshold8under EPCRA §313(f)(2) for a category of facilities with 

low amounts of a listed toxic chemical in wastes. A facility with such lower amounts of listed 

chemicals in wastes may submit an EPA Toxics Release Inventory Form A for the reportable 

chemicals instead of a Form R for each reportable chemical. Note that a Form A may contain 

multiple chemicals. Form A submissions foster continued attention to chemical management 

practices and provide important facility identification information. With a Form A, EPA and the 

general public receive a specific indication annually that a facility has a certain chemical; 

however, facilities provide less extensive reporting on chemicals when using the alternate 

threshold. 

The information collected on the Form R, or alternatively on the shorter Form A, fulfills EPA’s 

responsibilities under EPCRA §313(f)(2), addressing the statutory mandates and the public's rightto-know. Table 1 summarizes the information reported by facilities on the two types of TRI 

reporting forms.

 

8

EPA has authority to revise the threshold amounts pursuant to EPCRA §313(f)(2) provided that revised threshold

amounts still result in reporting on a substantial majority of total releases of the chemical at all facilities subject to 

EPCRA §313. A revised threshold may be based on classes of chemicals or categories of facilities.

2(b) Practical Utility/Users of the Data

The overall goal of the Toxics Release Inventory Program is to provide communities with 

information about toxic chemical releases and other waste management activities and to support 

informed decision making by industry, government, non-governmental organizations, and the 

public.9The Program’s success is due, in large part, to the right-to-know provisions contained in 

the legislation. By requiring that the resulting data be made publicly available "by electronic and 

other means," Congress ensured that the general public, the media, environmental advocates, 

researchers, the business community, and others could evaluate and influence industry's efforts to 

manage toxic emissions. Consequently, EPA makes available data collected under EPCRA §313 

and PPA §6607 through access tools such as EPA's Envirofacts, TRI Explorer, TRI.NET, and the 

web-enabled mobile myRTK. 

The TRI Program now provides the TRI Preliminary Dataset within weeks after the annual July 

1st TRI reporting deadline. The release consists of downloadable files on the TRI website (also 

accessible through Data.gov), as well as updated online data access tools (Envirofacts and TRI 

Explorer). 

The EPA generally makes available the annual TRI National Analysis and the final dataset used 

for that analysis within eight months after the reporting deadline. In addition to providing 

information to the public via electronic means, EPA also conducts outreach activities to make key 

groups and the public aware of TRI. Libraries in communities all across the United States (in 

particular, members of the Federal Depository Library Program) provide public access to TRI 

data. Environmental agencies, industry, and the public use TRI data. EPA program offices use 

TRI data, along with other data, to help establish programmatic priorities, evaluate potential

hazards to human health and the natural environment, and undertake appropriate regulatory and/or 

enforcement activities. Environmental and public interest groups use the data to better understand 

toxic chemical releases at the community level and to work with industry, government agencies, 

and others to promote reductions in toxic chemical releases. Industrial facilities use the TRI data to 

evaluate the efficiency of their production processes and to help track and communicate their 

progress in achieving pollution prevention goals. States use the TRI data to compare toxic 

chemical releases and other waste management approaches within specific industries and to set 

environmental priorities at the state level. See EPA’s The Toxics Release Inventory in Action: 

Media, Government, Business, Community and Academic Uses of TRI Data for more detailed 

descriptions of how these organizations use TRI data.10 EPA encourages TRI data users to provide 

feedback on ways to improve TRI products and services. 

3 NONDUPLICATION, CONSULTATIONS, OTHER COLLECTION CRITERIA

3(a) Nonduplication

The basic information requested on Form R/Form A is required to be reported by law. Other 

statutes, however, also necessitate the reporting of information about releases of chemicals to the 

environment, as well as transfers, treatment, and source reduction and recycling activities, creating 

the possibility of overlap or duplication of reporting requirements. EPA anticipates some overlap 

and notes that section 313(g)(2) of EPCRA specifies that respondents may use readily available 

data collected pursuant to other provisions of law to complete the EPCRA §313 reports. 

Information required by these other statutes may not provide readily accessible multi-media release 

and transfer, inventory, or pollution prevention data with the same scope, level of detail, chemical 

coverage, and frequency of collection as data currently included in TRI.

Several existing data sources contain media-specific data on releases and transfers, chemical 

inventory data, or pollution prevention information. In theory, information from these databases 

could be combined to form an analog of release and transfer data contained in TRI. However, 

given the currently available data sources (see Table 2 and Appendix C), this substitution is 

extremely unlikely. For example, differences exist across the databases in chemical coverage and 

facility coverage, as well as differences in the level of public access, reporting frequency, and the 

integration of data from various sources at the facility level. TRI contains information on releases, 

transfers, and other waste management activities for 594 individually listed chemicals and 30 

chemical categories—with total number of chemicals and chemical categories at 683. The following 

sections describe other sources of chemical releases and transfers, chemical inventory, and 

pollution prevention data and compare these sources with TRI.

Chemical Release and Transfer Data

TRI contains information on toxic chemicals handled by facilities, including details on quantities 

of chemicals managed through disposal or other release, recycling, energy recovery or treatment. 

These data include: 1) on-site releases with details on releases by environmental media (e.g., stack 

 

10 http://www2.epa.gov/sites/production/files/documents/tri_in_action_final_report_july_2013.pdf

or point air emissions, discharges to receiving streams or water bodies, etc.), and 2) off-site 

transfer data with details on the off-site locations that receive transfers and the disposal, treatment, 

energy recovery, or recycling methods used to manage the chemicals at the off-site locations. 

Waste management data include quantities that are treated, used for energy recovery, or recycled 

and are discussed in the section on pollution prevention below. 

Table 2 presents a summary of major databases containing release and transfer data that are 

discussed in this section. Appendix C provides a comprehensive list of relevant data sources.

a “Ease of substitution” refers only to the potential of the information in the database to substitute for TRI 

reporting. It does not imply that the database is not adequate for the purposes for which it was designed.

Air Releases

The 1990 amendments to the Clean Air Act require EPA to monitor and regulate the emissions of 

criteria air pollutants (CAPs) and hazardous air pollutants (HAPs), requiring EPA to identify the 

sources of these pollutants, quantify the sources by category, develop regulations, and then assess 
2/6/14

 

10

public health and environmental impacts. To facilitate this process, the Agency created two 

emissions inventories: the National Toxics Inventory (NTI) for HAPs and the National Emission 

Trends (NET) for CAPs. In 1999, the EPA combined these two databases to form the National 

Emissions Inventory (NEI) database.

NEI is EPA's compilation of estimates of air pollutants discharged on an annual basis and their 

sources. Five main categories organize NEI data: point sources (stationary), nonpoint sources 

(stationary), on-road sources (mobile), non-road sources (mobile), and events (fires). The

compilation includes emissions estimates submitted by state, local and tribal air pollution control 

agencies, emissions estimates calculated by EPA, and emissions obtained from other sources. 

EPA uses the NEI to track emissions trends over time, develop regional pollutant reduction 

strategies, set and analyze regulations, perform air toxics risk assessments including inhalation 

risks and multi-pathway exposure, model air pollutant dispersion and deposition, and measure 

environmental performance as required by the Government Performance and Results Act. 

Since 1996, EPA has compiled the NEI every three years. For 2008, the Agency reengineered the 

NEI business process to shorten the period between collecting data for a given inventory year and 

publication of that data. The most recent inventory is the 2011 NEI, which EPA published in 2013.

NEI and TRI data have many differences, including the type and number of pollutants measured, 

the industrial sectors included in the inventory, and the type of information collected (e.g., which 

environmental media releases are measured and what other release or management-specific 

information is collected). TRI includes 594 chemicals and 30 chemical categories known or 

reasonably anticipated to cause acute or chronic health effects or significant adverse environmental 

effects. NEI covers 8 Criteria Air Pollutants (CAPs) (i.e., carbon monoxide, volatile organic 

compounds, oxides of nitrogen, sulfur dioxide, particulate matter ≤ 2.5 microns, particulate matter 

≤ 10 microns, ammonia, and lead) and 187 Hazardous Air Pollutants (HAPs). TRI covers two of 

the CAPs (ammonia and lead) and 181 of the HAPs covered by NEI. NEI covers all sources of 

CAP and HAP emissions, including a number of sectors that are not included in TRI (e.g., 

agriculture, oil extraction and construction). In addition, NEI includes county-level emissions 

estimates for area, mobile and other sources not found in TRI.

Various reporting thresholds also differ between TRI and NEI. For example, a facility must report 

to TRI only if it has 10 or more full-time employee equivalents and manufactures, processes or 

otherwise uses any TRI-listed chemical in quantities greater than the established threshold 

(typically 25,000 pounds for manufacturing and processing and 10,000 pounds for otherwise use). 

PBT chemicals have lower thresholds for reporting to TRI. For HAPs, under NEI, a facility must 

participate in the point source inventory if it has the potential to emit ten or more tons per year of 

one HAP or 25 tons per year or more of any combination of HAPs. 

Information captured by TRI differs from that captured by NEI on a number of counts. TRI 

includes multimedia data on chemical releases, including air emissions and other types of releases 

(e.g., surface water discharges, underground injection, and landfill disposal of toxic chemicals). 

TRI also includes source reduction and waste management data, which can be used to assess 

pollution prevention trends on a facility basis. NEI focuses entirely on air emissions, but provides 
2/6/14

 

11

much more detailed emission source-specific data about releases, such as process descriptions, 

throughput and stack height. The different information captured by the data systems largely 

reflects the different goals behind the development of the inventories. TRI’s main purpose is to 

provide the public with information about potential chemical hazards, whereas NEI, among other 

purposes, seeks to produce data that would support modeling and risk assessment needs.

Water Discharges

The Integrated Compliance Information System–National Pollutant Discharge Elimination System 

(ICIS-NPDES)11 tracks the permit compliance and enforcement status of facilities that discharge to 

surface waters (www.epa.gov/enviro/facts/pcs-icis/search.html). For entities permitted to 

discharge wastewater into navigable waters, ICIS-NPDES contains information on permit issuance 

and expiration dates, quantities facilities are permitted to discharge, and monitoring data 

measuring facilities’ discharges. ICIS-NPDES data are not directly comparable to TRI; permit 

compliance data in ICIS-NPDES typically include monthly monitoring measures of pollutant 

concentrations in effluent discharges while TRI includes estimates of the total amount (in pounds) 

of a pollutant discharged to water. Monitoring required by the National Pollutant Discharge 

Elimination System (NPDES) covers only selected chemicals in the wastewater and does not 

comprehensively cover all TRI chemicals discharged to surface water at specific facilities.

Waste Disposal

Under the Resource Conservation and Recovery Act (RCRA), large quantity generators and 

treatment, storage, and disposal facilities submit information on the generation, management, and 

final disposition of RCRA-defined hazardous wastes. Every two years, filers must report the 

following information about each waste generated or managed in the preceding year: constituent 

waste codes; amounts generated; on- and off-site treatment, storage, and management; wastes 

received; and off-site shipment recipients. Facilities submit these biennial Hazardous Waste 

Reports to the state or EPA Regional office. The biennial reports (BR) include one year’s data 

(e.g., 2009 Biennial Report reflects data on waste management during 2009) and are stored 

centrally in EPA’s RCRAInfo. Biennial Reporting System (BRS) data do not duplicate the 

information contained within TRI, as: (1) hazardous waste codes do not necessarily map to unique 

chemicals; (2) quantities of specific chemicals in the waste stream cannot be determined; and (3) 

reporting occurs every other year, as opposed to annually for TRI.

Chemical Inventory Data

In addition to data pertaining to on-site management and transfers, a single element of the TRI form 

R requires reporting of the maximum amount of a chemical on site at any one time. Under EPCRA 

§312, the Emergency Response Program requires regulated facilities to submit annual inventory 

reports of hazardous chemicals stored on site to the state. Tier I requires reporting on broad 

categories of physical hazards, while Tier II requires chemical-specific information by CAS 

number. The information contained in the Tier I and Tier II reports surpasses the chemical inventory 

 

11 Note that ICIS-NPDES recently replaced the former Permit Compliance System (PCS).
2/6/14

 

12

data requested on TRI Form R in terms of the chemicals covered and level of detail. However, 

there is limited public access of Tier I and Tier II data because of restrictions due to security 

concerns.

Under §112(r) of the Clean Air Act, facilities with processes that use or store more than a specified 

amount of certain flammable and toxic substances must develop and implement a risk 

management program and submit to EPA a summary of their program—called a Risk 

Management Plan (RMP). These plans include the amounts (in pounds) of each substance that are 

processed or used, hazard assessments of the potential effects of hypothetical accident scenarios, a 

five-year history of accidental releases involving regulated substances at the facility, and 

information about the facility’s accident prevention and emergency response programs. Facilities 

with processes that use or store more than a threshold amount (500–20,000 pounds) of a listed 

chemical must file an RMP and update their filing at specified times, including following a 

significant accidental release. TRI data do not duplicate RMP data as: (1) RMP covers only 54 of 

the 683 TRI chemical and chemical compound categories;12 (2) some RMP data are considered to 

be confidential business information (CBI) and are therefore not publically available; and (3) RMP 

reporting occurs every five years, as opposed to annually for TRI.13

Under Section 8(a) of the Toxic Substances Control Act (TSCA), chemical manufacturers 

(including importers) must report to EPA’s Chemical Data Reporting (CDR) every four years. 

Facilities must report manufacturing-related information for sites that manufactured (including 

imported) 25,000 pounds or more of a reportable chemical substance during any one calendar year 

between submission periods. Facilities must also report industrial processing and use information 

as well as commercial and consumer use information. CDR contains more detailed inventory 

information than TRI; for example, CDR includes chemical concentration and physical form data 

not found in TRI. CDR also contains a broader range of chemicals than TRI; in a typical CDR 

reporting cycle, EPA collects information for about 7,000 to 8,000 chemicals. However, CDR’s 

base for information collection is much narrower than that for TRI. CDR reporting requirements 

only apply to chemical manufacturers (including importers). CDR reporting requirement do not 

apply to industrial facilities in other sectors that process or otherwise use chemicals.

Pollution Prevention Data

TRI also collects pollution prevention data from reporting facilities. These data include quantities 

of chemicals managed as waste by waste management practice (e.g., recycling, energy recovery, 

etc.) and source reduction activities implemented at the facility. 

Under the Resource Conservation and Recovery Act (RCRA), facilities must report pollution 

prevention data in their Biennial Hazardous Waste Reports (described above). While BR data 

provide qualitative and quantitative pollution prevention information, facility and chemical 

coverage is not directly comparable to data required for TRI reporting. BR contains data on

13

generation, transfer, and management of hazardous wastes; TRI reporting requires data on toxic 

chemicals in waste streams or process by-products (all production phases and media). 

Under various state regulations, at least fourteen states14 implement mandatory pollution 

prevention programs for TRI filers, facilities that use toxic chemicals, or generators of 

hazardous waste. Pollution prevention data are collected under these programs and stored in 

databases administered by state environmental agencies. The types of pollution prevention 

data collected vary by state, and may include both data similar to that collected by TRI (e.g., 

quantities of waste managed, source reduction activities) and details not found in TRI (e.g., 

pollution prevention plans, costs associated with waste management, etc.). However, no 

federal or state program collects all of the pollution prevention data currently required by TRI.

3(b) Public Notice Required Prior to ICR Submission to OMB

This Supporting Statement is part of EPA’s request to renew the existing approved Form R/A 

ICR which is scheduled to expire on October 31, 2014. Before submitting the ICR renewal to 

OMB for review and approval, EPA is soliciting comments on specific aspects of the 

proposed information collection. A Federal Register Notice is being published to announce 

this renewal request and the availability of this Supporting Statement for review by the public.

3(c) Consultations

EPA has consulted with a large number of individuals and organizations throughout all segments 

of the public in the development and continued implementation of the TRI Program. EPA has 

received feedback from environmental and public interest groups, trade associations, educational 

institutions, individual representatives, and others through its outreach efforts in venues such as:

 meetings with stakeholders to provide TRI program updates and obtain input on 

rulemakings; 

 on-line dialogues to discuss issues and obtain input on potential rulemakings;

 webinars to provide training on various topics, including expanding the use of TRI for 

environmental justice; and

 the TRI National Training Conference, held every 18-24 months.

For more specific information on meetings and organizations consulted, see Appendix D. EPA 

continually seeks this feedback and incorporates it into the ongoing evolution of the TRI Program.

3(d) Effects of Less Frequent Collection

Section 313 requires annual reporting. Section 313(i) permits EPA to modify the reporting 

frequency by rulemaking; however, EPA must first notify Congress and then delay the 

initiation of such a rulemaking for at least 12 months, but no more than 24 months, from the

 

14 Arizona, California, Georgia, Maine, Massachusetts, Minnesota, Mississippi, New Jersey, New York, Oregon, 

Tennessee, Texas, Vermont, and Washington. 
2/6/14

 

14

date of the notification. In addition, EPA must find: that the modification is consistent with the 

provisions of subsection (h) of §313 based on:

(i) experience from previously submitted toxic chemical release forms; and

(ii) determinations made under paragraph (3).

Paragraph (3), in turn, provides that EPA must determine:

(A)The extent to which information relating to the proposed modification provided on 

the toxic chemical release forms has been used by the Administrator or other 

agencies of the federal government, states, local governments, health professionals 

and the public.

(B) The extent to which information is (i) readily available to potential users from other 

sources, such as state reporting programs, and (ii) provided to the Administrator under 

another federal law or through a state program.

(C) The extent to which the modification would impose additional and unreasonable 

burdens on facilities subject to the reporting requirements under this section.

Since TRI represents the best available multi-media database for tracking toxic chemical releases 

in the United States, a change in the reporting frequency to less than once a year could have a 

significant impact on the availability of timely toxic chemical data and affect data users, 

particularly at the community level. Additionally, public access to the most current toxic chemical 

release data and other waste management information would become more difficult. 

3(e) General Guidelines

This ICR adheres to the 1995 Paperwork Reduction Act, as amended, OMB's implementing 

regulations, and all applicable OMB guidance.

Although reporting facilities must identify the chemical for which they submit reports, they 

can claim the chemical identity as a trade secret. In such circumstances, facilities provide a 

generic name as part of the information made available to the public. EPA securely stores 

and maintains the true identity of the chemical (see also Section 3(f) below). 

Effective January 21, 2014, EPA requires the electronic submission of TRI Form R/Form A 

through the Internet via EPA’s Central Data Exchange (CDX) by using the Toxics Release 

Inventory Made Easy Web (TRI-MEweb) reporting software. TRI-MEweb helps facilities 

prepare high-quality reports more easily than they could using paper reporting forms due to a 

number of technology advances, including built-in data quality checks. 

Small facilities (with fewer than 10 full-time employees or the equivalent) are exempt from 

reporting under EPCRA §313. Two particular provisions that apply to TRI reporters universally: 
2/6/14

 

15

1) the optional range reporting provision 15 and 2) an alternate threshold allowing Form A 

eligibility, are particularly beneficial to non-exempt smaller facilities with small releases and 

wastes.

3(f) Confidentiality 

Respondents may designate the specific chemical identity of a substance as a trade secret 

according to EPCRA §322. Procedures for submission and review of trade secret claims under 

EPCRA §313 are set forth in 40 CFR 350. When a facility claims the chemical identity to be a 

trade secret and properly substantiates the claim, EPA will not disclose the identity of the 

chemical to the public. EPA securely stores forms with trade secret information and allows 

access to those documents only to persons with Trade Secret clearance. Data made available to 

the public through any means do not include trade secret information.

3(g) Sensitive Questions

This collection does not request any sensitive information.

4 THE RESPONDENTS AND THE INFORMATION REQUESTED 

4(a) Respondents/NAICS Codes

The reporting requirements found in EPCRA §313 apply to owners and operators of facilities that 

have 10 or more full-time employee equivalents (i.e., a total of 20,000 hours worked per year or 

greater; see 40 CFR 372.3); are included in a North American Industry Classification System 

(NAICS) Code listed at 40 CFR 372.23 or under Executive Order 13148, federal facilities 

regardless of their industry classification; and manufacture (defined to include importing), process, 

or otherwise use any EPCRA section 313 (TRI) chemical in quantities greater than the established 

thresholds for the specific chemical in the course of a calendar year. Historically the TRI-covered 

industrial sectors were identified by their Standard Industrial Classification (SIC) codes. 

Beginning with Reporting Year (RY) 2006, the TRI Program converted from SIC codes to North 

American Industry Classification System (NAICS) codes (71 FR 32464, June 6, 2006). The full 

list of NAICS codes for facilities that must report to TRI (including exemptions and/or 

limitations), if all other threshold determinations are met, can be found in Appendix E. 

 

15 Range reporting provides an option for releases of less than 1,000 pounds to be recorded as a code representing 

one of three ranges (1 to 10 pounds, 11 to 499 pounds, or 500 to 999 pounds) rather than as a specific estimate of 

the release amount. Range reporting is not permitted on Form Rs for PBT chemicals. For further discussion, see 

Section 5(c).
2/6/14

 

16

4(b) Information Requested

(i) Data Items, Including Recordkeeping Requirements 

Appendix A provides a copy of the proposed Form R, Form R Schedule 1 and Form A. For 

instruction revisions associated with the proposed form revisions, see Appendix B. To access 

existing TRI Reporting Forms and Instructions, see http://www.epa.gov/tri/report/#forms.

Form R

Facilities reporting to TRI report releases and other waste management of listed chemicals on 

Form R. The required data items, summarized below, are specified in 40 CFR §372.85. Form R 

consists of two sections. In Part I, respondents report facility identification information including: 

facility identification number; facility name and address; NAICS code; facility Dun and Bradstreet 

(D&B) number; parent company name; parent company D&B number; name, email address, and 

phone of the technical contact; and name, email address, and phone of the public contact. In Part 

II, respondents report:

 Toxic chemical identity,

 Mixture component identity,

 Activities and uses of the toxic chemical at the facility,

 Maximum amount of the toxic chemical on site at any time during the calendar year,

 Quantity of the toxic chemical entering each environmental medium on site,

 Transfers of the toxic chemical in wastes to off-site locations,

 On-site waste treatment methods and efficiency, and

 Source reduction and recycling activities.

On Form R Schedule 1, facilities reporting on dioxin and dioxin-like compounds report the 

individual grams data for each member of the dioxin and dioxin-like compounds category present. 

Form R Schedule 1 is a four-page form that mirrors the data elements from Form R Part II 

Chemical-Specific Information sections 5, 6, and 8 (current year only).

Form A

Form A also consists of two sections. Part I solicits the same information as Part I of Form R 

(see list above) but requires a different certification statement which represents a signed 

statement by a facility owner/operator or senior management official. In contrast to Form R 

where reduced threshold eligibility is not an issue, the Form A’s signed statement certifies that 

the annual reportable amount as defined by 40 CFR 372.27(a) did not exceed 500 pounds for the 

reporting year, and that the amounts manufactured, or processed, or otherwise used did not 

exceed 1 million pounds for that year. In most instances, PBT chemicals may not be reported 
2/6/14

 

17

using Form A.16 In Part II, a facility may report multiple chemicals on a single Form A. 

Specifically Form A solicits: 

 Toxic chemical identity, and

 Mixture component identity.

In addition to annual reporting requirements, facilities must maintain records used to provide the 

information required on the form according to 40 CFR §372.10. Those records may include 

estimation methodology and calculations; engineering reports; inventory, incident, and operating 

logs; and other supporting materials. Facilities must keep a copy of each report filed for at least 

three years.

Proposed Form Revisions

As mentioned above, EPA is proposing revisions to the Form R and Form A that clarify data 

elements and enhance data utility. Specifically, the revisions to the forms and rationale for the 

revisions are presented in Table 3.

 

16 The exception is lead in stainless steel, brass, or bronze alloys, which are not excluded from Form A 

eligibility.
2/6/14

Table 3

Proposed Form Revisions

Form Revision Rationale Form

1 Add an optional extension to all 

phone numbers to allow facility 

representatives to provide the 

extension needed for a direct 

connection. (Part I: Section 4)

The phone number provided is often the main company line. 

Many companies have extensions for direct connection with 

employees. Addition of the optional phone extension would 

allow facilities to ensure that incoming calls are directed to the 

appropriate person. 

R/A

2 Add an optional field for the reach 

code corresponding with the 

receiving water body for each 

surface water discharge. (Part II: 

Section 5.3)

40 CFR §372.85(b)(7) requires facilities to include on their 

form Rs “the name(s) of receiving stream(s) or water body to 

which the chemical is released.” Water body name is not a 

unique identifier, however, and a single water body can cover 

a large and disparate geographic area. Therefore, in order to 

model the potential impact of chemical discharges on 

downstream and intermediate receiving water bodies, EPA and 

other regulatory agencies, researchers, and analysts use the 14-

digit reach code assigned in the USGS’s National 

Hydrography Dataset (NHD). 

These reach codes identify a continuous piece of surface water 

with similar hydrologic characteristics. Once linked to the 

NHD by their reach code, the upstream/downstream 

relationships of water-related entities such as drinking water 

supplies, fish habitat areas, or wild and scenic rivers can be 

analyzed using software tools ranging from spreadsheets to 

Geographic Information Systems (GIS) and the potential 

cumulative environmental impacts of TRI chemical can be 

assessed.

While optional, this field would populate automatically when a 

user selects their receiving water body on the map provided in

the TRI-MEweb interface for this section. 

R

3 Move the header “5.5 Disposal to 

land on-site” to precede Sections 

5.4 and 5.5 on Form R so that it 

covers both 5.4 and 5.5. Re-word 

5.4.1 and 5.4.2 to fit under the new 

header as follows: Section 5.4-5.5: 

Disposal to land on-site, Section 

5.4.1: Class 1 Underground 

Injection Wells, Section 5.4.2 

Class II-V Underground Injection 

Wells. (Part II: Section 5.4-5.5)

This change would clarify that releases to underground 

injection wells are considered releases to land.

R
2/6/14

 

19

4 Provide the heading, “Productionrelated waste managed” for 

Sections 8.1-8.7 and re-label 

Section 8.8 “Non-productionrelated waste managed,” with a 

footnote indicating that this 

Section “includes quantities 

released to the environment or 

transferred off-site as a result of 

remedial actions, catastrophic 

events, or other one-time events 

not associated with production 

processes” (Part II: Section 8.1-

8.8).

Form R does not currently indicate that quantities reported in 

Sections 8.1 through 8.7 are exclusive of the amounts reported 

in Section 8.8. Adding the labels “Production-related” and 

“Non-production-related” waste managed would mirror the 

terminology used to describe these data elements in TRI tools 

and the TRI National Analysis and clearly delineate which 

releases and transfers to report in which Sections. 

R

5 Add checkboxes to indicate 

whether the facility has provided a 

“Production Ratio” or an “Activity 

Ratio” (Part II: Section 8.9).

Section 6607(b)(5) of the PPA requires facilities to submit a 

ratio of production in the reporting year to production in the 

previous year. Where some variable other than production is 

the primary influence on waste characteristics or volumes, 

facilities may base this ratio on the primary influencing 

variable. The existing form does not specify which type of 

ratio was used and thus limits the utility of this metric. 

Additionally, “production or activity ratio” is a more precise 

description of this Section than “production ratio or activity 

index” since the metric reported is a ratio regardless of 

whether production or some other activity variable is used.

R

6 Add a new column where the 

facility can provide an optional 

percentage range indicating the 

estimated annual reduction in 

chemical waste generation 

associated with a given source 

reduction activity (Part II: Section 

8.10).

This change would make it easier to report and assess the 

effectiveness of different types of source reduction activities 

and thus promote the adoption and recognition of successful 

pollution prevention practices. To simplify reporting, facilities 

would report their estimates using one of six percentage ranges 

(just as treatment efficiencies are reported in ranges in Section 

7). While optional, completion of this Section would be a 

simple way for a facility to highlight positive steps it has taken 

to reduce releases of toxic chemicals to the environment.

R

7

Provide optional barrier codes in 

Section 8.11 that facilities can use 

to indicate why they could not 

implement any source reduction 

activities during the reporting year 

(Part II: Section 8.xx).. 

Facilities are required to pick a code if they perform a new 

source reduction activity. However, there is currently no way 

for a facility to indicate why they didn’t implement a source 

reduction activity. While these codes would be optional, it 

would allow EPA to assist facilities in overcoming barriers to 

implementing source reduction activities.

R

8 Allow facilities to categorize 

optional free-text information 

entered in Sections 8.11 and 9.1 by 

selecting from a list of topics 

provided in TRI-MEweb (Part II: 

Section 8.11 and Section 9.1).

Letting facilities flag their free-text entries as relevant to 

certain commonly-used topics would improve TRI tools that 

display free-text information, data quality efforts, and overall 

analytical utility of the dataset.

R

Proposed Revision to TRI-MEweb
2/6/14

 

20

Additionally, the EPA proposes modifying TRI-MEweb to collect, as optional, information that 

some facilities have historically provided, unsolicited, to EPA on matters related to TRI 

(collectively called miscellaneous TRI documents). Examples of these miscellaneous TRI 

documents include updates to contact and location information for the facility and reasons for nonreporting. Some of this information is useful to the Agency and could be useful to the public. 

Currently, the EPA receives this unsolicited information on paper. 

This proposed modification would allow for an online means for the EPA to receive miscellaneous 

documents, therefore reducing the cost of processing their submission and aligning how EPA 

processes such documents with the recent requirement to submit TRI reporting forms 

electronically. In other words, with this change, facilities could use TRI-MEweb to provide details 

on specific categories of information that they have been providing on a voluntary basis to the 

EPA throughout the existence of the program (e.g., supplemental information on updates to the 

facility’s name, status, location, and/or parent company; supplemental information on updates on 

whom to contact for technical and/or public matters; and reasons for not reporting (indicating the 

facility did not meet thresholds or did not report for any other appropriate reason)). Receipt and 

processing of this information would not affect any reporting forms certified and submitted to the 

agency, but rather would allow facilities to provide an electronic means to submit contextual 

information concerning their facilities that can enhance the context of TRI data for the EPA as 

well as for the public.

(ii) Respondent Activities

Facilities engage in a number of activities to comply with the EPCRA §313 reporting 

requirements. These activities fall into two distinct groups: Form Activities, consisting of rule 

familiarization, compliance determination, calculations and form completion, and recordkeeping 

and submission; and Non-Form Activities, consisting of supplier notification, non-reporter 

compliance determination, and petitions. 

Form Activities

 Rule Familiarization: Staff of a facility that is reporting under EPCRA §313 for the first 

time must read the reporting package and become familiar with the reporting requirements. 

This includes the time needed to review instructions, and the time needed to train personnel to 

respond to a collection of information.

 Reporter Compliance Determination: At reporting facilities staff must make the 

determination that the facility meets the criteria for EPCRA §313 reporting. This activity 

includes the time required to become familiar with the definitions, exemptions, and 

threshold requirements under the TRI Program, to review the list of TRI chemicals, and to 

conduct preliminary threshold determinations to determine if the facility is required to 

report.
2/6/14

 

21

 Calculations and Form Completion: Facility staff must gather data and perform 

calculations to provide the information required on the form. This activity includes the time

required to search data sources and the time to complete and review the information.

 Recordkeeping and Submission: Facility staff must maintain recordkeeping systems and 

submit the report to EPA and the state in which the facility is located. This activity includes 

the time required to transmit or otherwise disclose the information.

Non-Form Activities

 Supplier Notification: Certain suppliers of mixtures or trade name products containing 

reportable substances must annually notify their customers of the product's composition, if the

customer is subject to EPCRA §313 reporting. This activity includes the time required to 

inform customers, either by letter or through the materials safety data sheet (MSDS) for the 

product.

 Non-Reporter Compliance Determination: In any given reporting year, a group of eligible 

facilities will complete compliance determination but will not file a Form R or Form A. The 

activity is the same as is presented above under Form Activities; however, given that 

compliance determination applies to all other facilities in NAICS-code-eligible sectors (with 

ten or more employees)—including those that ultimately do not report to TRI—this separate 

activity accounts for the latter category. 

 Petitions: Any person may petition the EPA to add or delete a chemical from the TRI toxic 

chemical list. EPA evaluates the toxicity of the chemical against the listing criteria 

established by Congress and makes a determination whether to grant or deny the petition 

request. If the petition is granted, EPA will propose a rule to either add or delete the 

chemical and after reviewing the public comments will issue a final rule. If the petition is

not granted, EPA issues a notice explaining why the petition was denied. The activities 

required to prepare and file a petition include the following: 

 Read EPA policy and guidance documents and consult with EPA;

 Plan activities;

 Prepare literature search;

 Conduct literature search;

 Process, review, and focus information; 

 Write petition;

 Review and edit petition; and

 Submit petition to EPA and file.

EPA provides the reporting community with instructions, guidance documents, training materials, 

and toll-free hotlines to assist them in completing and submitting their reporting forms to EPA. 
2/6/14

 

22

5 THE INFORMATION COLLECTED—AGENCY ACTIVITIES, COLLECTION

METHODOLOGY, AND INFORMATION MANAGEMENT

5(a) Agency Activities

EPA engages in many activities to fulfill the purpose and requirements of EPCRA. These activities 

fall into the following categories that cover what the Agency does to assist the regulated community 

with compliance, to process the data, to maintain the database, and to make the data available:

 Assistance to Reporters;

 Electronic Reporting;

 Paper-Based Reporting (limited to trade secret reporting forms);

 Data Processing and Quality Control;

 Database Organization;

 Links to State Reporting;

 Making Data Available;

 List Revisions and Petition Reviews;

 Trade Secrecy Reviews.

Assistance to Reporters. The Agency operates an outreach program to assist reporters with 

activities related to Form R (including Schedule 1)/Form A completion. EPA provides TRI 

reporting assistance with a variety of online tools and guidance, including TRI Reporting Forms 

and Instructions and TRI-MEweb (TRI Made Easy) reporting software. TRI-MEweb is a Webbased software application that TRI facilities can use for entering, validating and submitting 

their data. The TRI Program also provides both basic and advanced downloadable TRI training 

slides plus online audio training modules on the TRI website. 

EPA operates two toll-free hotlines to answer general questions and questions pertaining to 

electronic reporting and data certification over the internet. In addition, the Agency maintains a 

website with current program-specific information and guidance (http://www.epa.gov/tri). 

General guidance has been prepared for estimating releases, including 14 industry-specific 

guidance documents. Additionally, EPA provides guidance and assistance for persons or 

organizations regarding petitions to add or delete chemicals from the TRI list.

Electronic Reporting. As observed in 2013 for reporting year (RY) 2012, close to ninety-eight

percent of all TRI Form Rs and Form As were prepared and submitted electronically using 

TRI-MEweb. 17,18 Capabilities in TRI-MEweb include:

 

17 Based on TRI 2012 baseline dataset from EPA 11/08/2013. 

18 Prior to TRI-MEweb, TRI reporting software had been desktop-based, distributed via the TRI Web site and mailed

directly to facilities (via CD-ROM) each year. In RY 2007, TRI-MEweb, the new Web version of TRI-ME, was fully 

launched. The TRI-ME desktop software was retired from service in RY 2009.
2/6/14

 

23

 Easy Upload and Validation Checks. Facilities can key, preload from a prior year 

submission or upload their data into TRI-MEweb. TRI-MEweb also provides facilities 

with extensive data validation checking through point-of-entry edit checks as well as a 

cumulative, mandatory validation checks prior to submission. 

 Submittal to the Central Data Exchange (CDX). After facilities enter and validate 

their data, certifying officials must electronically sign (i.e., certify) forms within TRIMEweb. 

 Automatic Data Transmittal. Once a facility’s certifying official has certified its TRI 

submission, CDX automatically forwards it to the TRI EPCRA Data Processing Center 

(DPC), which loads it into the TRI Processing System (TRIPS) database. The TRIPS 

database is located at EPA’s National Computer Center in Research Triangle Park, NC. 

 TRI Submission shared with States. Through the TRI Data Exchange, facilities can 

submit the data via CDX, which transmits the data to both EPA and the participating 

state government. This reporting option allows facilities to fulfill their legal obligation 

to report to both EPA and the appropriate State through a single transmission of data to 

CDX. 

 Preloaded Forms and Central Data Storage. The TRI-MEweb application allows 

users to preload their forms with prior year data stored in an EPA-maintained database. 

This database is separate from the TRIPS database, which stores certified TRI 

submissions. 

 Quick Lists. TRI-MEweb provides “quick lists” that allow users to narrow their data 

entry to only the pertinent areas. 

 Data Quality Checks. TRI-MEweb contains a number of data quality checks including 

internal consistency and semantic checks that compare a facility’s data to prior year 

submissions. 

 On-Line Revisions and Withdrawals. The application allows online revision and 

withdrawal of data by facilities. Through this feature, facilities can access previously 

submitted forms, and revise or withdraw as needed. 

 Automated Section 8 Calculator. TRI-MEweb automatically calculates Section 8 

Column B (current year) estimates based on data entered in other form sections. Users may 

tailor the calculation's inputs, but cannot enter their own calculated values. This approach 

aims to reduce the frequent mathematical errors in Section 8 and simplify the reporting 

process. 

 TRI Assistance Library. An online TRI Assistance Library (TRIAL) is available to help 

facility reporters complete their TRI submissions. 

Paper-Based Reporting. As of January 21, 2014, only facilities submitting trade secret 

reporting forms are allowed to submit data to TRI on paper forms. Facilities submitting trade 
2/6/14

 

24

secret forms must submit two forms, one that is trade secret and one that is sanitized. The trade 

secret form goes into a separate database, and EPA keys the sanitized information into the 

TRIPS database. Automated data quality checks begin at data entry. At this point, the emphasis 

is on identifying forms that are not completed correctly and cannot be processed further 

because of fundamental errors (e.g. no chemical specified). 

Data Processing and Quality Control. EPA no longer processes paper forms as of RY 2013. EPA 

only performs additional validation checks of electronic data that have been certified by TRIMEweb and sent for processing into TRIPS through CDX. The validation checks look for duplicate 

records and determine if a facility reconciliation is required before the data are released. EPA also 

conducts a set of data quality checks that compare the incoming data with prior years’ data and 

various data threshold checks. 

Upon passing the data validation and quality checks in TRIPS, EPA generates an electronic Facility 

Data Profile (eFDP) report and makes it available for facility review through TRI-ME web. The 

report contains an echoing back of the data and confirms that all validation checks have passed and 

that the facility’s data have been processed into the TRIPS database. However, as of RY 2013, the 

eFDP report can no longer be used by facilities to manually correct data submitted to EPA. 

Database Organization. EPCRA §313(j) requires EPA to make TRI data available to the public 

through computer telecommunications and other means. EPA ensures that each facility has a 

unique identifier—the TRI facility ID (TRIFID). EPA generates a TRIFID for newly reporting 

facilities at the time of data entry. The identification number allows easy retrieval of cross-year 

data, even when a facility is sold or changes its name. Facilities receive notification of their 

TRIFID and must use it consistently over time. 

Links to State and Indian Country Reporting. EPCRA §313 requires facilities to submit forms 

to both EPA and the state or Indian country agency in which they operate. For coordination, 

tracking, and quality assurance purposes, EPA, state, and Indian country agencies reconcile 

their submissions at the end of the reporting cycle. 

In 2004, EPA implemented the TRI State Data Exchange (now referred to as the TRI Data 

Exchange (TDX)), which enables facilities to simultaneously submit their data to EPA and the 

State or Indian country in which they are located. There are currently 48 TDX participants. This 

reporting option allows facilities to fulfill their legal obligation to report to EPA as well as the 

State or Indian country through the sole submission of data through CDX. 

Making TRI Data Available. There are many options available for accessing TRI data - ranging 

from data files to refined analyses. The annual TRI National Analysis is an overview of the most 

recently reported TRI data. It includes key findings, in-depth analyses, and information on trends. 

Two on-line data access tools, TRI Explorer and Envirofacts, make TRI data available to the 

public for further analysis. In addition, the public can download a desktop application, TRI.NET, 

from the TRI website. TRI.NET allows users to build custom reports of TRI data, to view and 

analyze TRI data using geospatial capabilities, and to combine TRI data with other related data for 
2/6/14

 

25

further analysis. Envirofacts provides Web services that allow developers to include dynamic TRI 

data queries in their applications.

The TRI Program historically did not release the latest year of TRI reported data until the release 

of the TRI National Analysis. However, starting in 2009, EPA began releasing the most recent 

year of TRI data within weeks after the July 1st reporting deadline. EPA provides the TRI 

preliminary dataset in downloadable data files, as well as via TRI Explorer, Envirofacts and Web 

services. Note, however, that these data have not undergone the manual data quality checks and 

verifications that EPA conducts prior to the TRI National Analysis release.

List Revisions and Petition Reviews. The list of toxic chemicals subject to reporting under 

EPCRA §313 may undergo changes. EPA can initiate regulatory additions or subtractions of 

chemicals from the list of TRI-covered chemicals, either independently or in response to a 

petition. 

Trade Secrecy Reviews. Facilities claiming a chemical identity as a trade secret must substantiate 

the claim by completing the Trade Secret Substantiation Form available from the TRI website 

(www.epa.gov/tri) under "TRI Reporting Materials." For more information on trade secrecy 

reviews, including the costs to EPA, see the ICR for the Trade Secrecy Rule for EPCRA (EPA 

#1428, OMB #2050-0078).

5(b) Collection Methodology and Management

As of January 21, 2014, EPA requires electronic submission of all non-trade secret reporting 

forms through the Internet via EPA’s CDX and the TRI-MEweb application. Note that for RY 

2012, filers prepared close to ninety-eight percent of all TRI submissions using TRI-MEweb and 

submitted electronically to EPA via CDX. 

5(c) Small Entity Flexibility

Under EPCRA §313 (b)(1)(A), facilities with fewer than 10 full-time employees (or the 

equivalent) do not have to report. In addition, EPA has taken several steps to minimize the 

burden for covered small businesses. EPA added a range reporting option to the Final Rule (53 

FR 4500, February 16, 1988), which codified the EPCRA §313 reporting requirements. Range 

reporting was the preferred option from the Regulatory Flexibility Act analysis to provide 

burden reduction for small businesses. Range reporting provides an option for releases of less than 

1,000 pounds to be recorded as a code representing one of three ranges (1 to 10 pounds, 11 to 

499 pounds, or 500 to 999 pounds) rather than as a specific estimate of the release amount. The 

benefit is not, however, limited to small businesses. Note that facilities may not use range 

reporting on Form Rs for PBT chemicals.

In response to a petition from the Small Business Administration, EPA promulgated the alternate 

threshold (59 FR 61488, November 30, 1994), manifested in Form A reporting, as discussed in 
2/6/14

 

26

Section 1(b). Although any reporting facility meeting the criteria may use the alternate threshold, 

this alternate threshold may be particularly advantageous to small entities. 

5(d) Collection Schedule

Facilities must report their information on a calendar-year basis, and submit Form Rs or Form As 

to EPA by July 1 of the following year. In response to public requests to shorten the time frame 

for release of TRI information, TRI began a modernization effort in 2007 that included transition 

to TRI-MEweb from desktop software, and a number of streamlining initiatives. One of the 

resultant improvements was the Preliminary Data Release which provides TRI database 

information as quickly as possible after the reporting deadline. Since 2010, EPA has released data 

less than one month after the reporting deadline in the TRI preliminary dataset with downloadable 

data files and access via TRI Explorer and Envirofacts. 

6 ESTIMATING THE BURDEN AND COST OF THE COLLECTION 

This information collection activity imposes burden and cost on certain facilities affected by 

EPCRA §313 reporting requirements. It also imposes costs on EPA to process and make available 

the data collected and stored in the Toxics Release Inventory. The following sections present the 

derivation of Form R and Form A respondent burden and cost as well as Agency burden and cost. 

For TRI reporters, the following sections present estimates of average Form R and Form A 

reporting burden per respondent. EPA develops unit costs by combining these form-level unit 

burden estimates with an appropriate wage rate. Combining the universe of reporting forms with 

estimates of unit burden and cost provides an estimate of Total Form R and Form A respondent 

burden and costs. This universe of reporting forms consists of reporting in RY 2012 plus updates 

to reflect changes during the year of the ICR project—in this case, the modeled number of 

chemicals and facilities estimated to report under the Addition of ortho-Nitrotoluene rule, 

published on November 7, 2013, and the Electronic Reporting of TRI Data rule, published on 

August 27, 2013. The combined total number of forms and facilities (i.e., respondents) is hereafter 

referred to as the ICR Universe. The methodology used to estimate reporting burden in this ICR 

Renewal—Ratio-Based Burden Methodology (RBBM)19 —is a restructured and simplified 

formulation of the previously employed methodology.20 When estimating reporter burden using 

RBBM, the Nominal Form R unit burden (35.70516 hours) is the base number and Form A unit 

burden is set at 61.5% of that value. These unit burdens reflect burden associated with form 

activities including rule familiarization, reporter compliance determination, calculations and form 

completion, and recordkeeping. In addition to Form R and Form A burden, total TRI program 

burden is captured by adding non-form burden associated with supplier notification, non-reporter 

compliance determination, and petitions to form burden.

OMB approved a combined Form R/Form A ICR on October 14, 2011, with an expiration date of 

October 31, 2014. The OMB approved burden estimate at that time was a total of 3.52 million 

hours. Several changes in the reporting requirements have occurred since OMB’s approval of the 

ICR on October 14, 2011.21 Specifically:

 On October 17, 2011, EPA lifted the Administrative Stay of the Toxics Release Inventory 

reporting requirements for hydrogen sulfide. EPA received the first submissions for 

hydrogen sulfide for reporting year 2012; the total number of form submissions used to 

calculate the overall program burden therefore includes these hydrogen sulfide 

submissions. 

 On April 19, 2012, EPA published a rule requiring facilities located in Indian country to 

report to tribal governments beginning with TRI reporting year 2012 (TRI reports due by 

July 1, 2013). On December 10, 2012, OMB approved a change in the program burden 

hours (due to rule familiarization only) for Form R and Form A to reflect passage of the 

TRI Reporting for Facilities located in Indian Country rule, increasing burden by 6,985 

hours. This burden applies in the first year of the rule only, and is prior to this ICR 

renewal period. Therefore, this rule adds no ongoing steady state burden to the TRI 

program. 

 On July 18, 2013, EPA published a rule updating the list of North American Industry 

Classification System (NAICS) codes subject to reporting under the Toxics Release 

Inventory (TRI) to reflect the Office of Management and Budget (OMB) 2012 NAICS 

revision. Facilities would be required to use 2012 NAICS codes when reporting to TRI 

beginning with TRI reporting forms that are due on July 1, 2014, covering releases and 

other waste management quantities for the 2013 calendar year. EPA estimated no 

additional reporting burden due to this rule as it adds no new reporting requirements.

 On August 27, 2013, EPA published a rule requiring facilities to report non-trade secret 

Toxics Release Inventory (TRI) forms to EPA using electronic software provided by the 

Agency. EPA estimated burden under three possible scenarios for this transition. Expected 

ongoing steady state burden equals approximately $1,000 in capital costs (i.e., total 

ongoing Internet costs for facilities who do not already have Internet access).

 Lastly, on November 7, 2013, EPA added ortho-Nitrotoluene (o-Nitrotoluene) to the list of 

toxic chemicals subject to reporting under section 313 of the Emergency Planning and 

Community Right-to-Know Act (EPCRA) of 1986 and section 6607 of the Pollution 

Prevention Act (PPA) of 1990. EPA estimates that this rule will increase the number of 

newly reporting facilities by 1 and the total number of Form Rs and Form As submitted by 

17 and 5 respectively, with an associated ongoing steady state burden increase of 717 

hours. 

Based on the latest data for RY 2012 with updates to reflect the estimated additional reporting 

resulting from the Addition of the o-Nitrotoluene rule, EPA now estimates the total number of 

combined Form R and Form A responses to be 74,869, the associated total annual burden hours to 

be 3.56 million and the annual cost to be $183.4 million (see Section 6(b) for breakdown by Form

burden, see Figure 2 and Table 18.

R, Form A, and non-Form contributions). These estimates incorporate the proposed revisions to 

Form R and Form A which have been estimated to have a negligible impact on form burden.

Agency burden and cost associated with the TRI Program includes RFI and Compliance 

Assistance; TRI Reporting Software and Related Data Collection/Exchange IT Infrastructure, and 

Data Processing. Section 6(b) presents the Agency’s burden and cost of these activities. 

6(a) Estimating Respondent Burden

This section presents the burden of this information collection activity to Form R and Form A 

respondents in terms of the time required for facility personnel to perform the activities outlined 

in Section 3 of this document. As was done in the previous ICR, this ICR Renewal uses EPA’s 

new Ratio-Based Burden Methodology (RBBM), to estimate TRI respondent burden for both 

Form R and Form A reporting.22

Ratio-Based Burden Methodology simplifies calculations, supports internal consistency, and 

sharpens transparency while retaining the components of the previous methodology and 

maintaining its overall total burden estimate as a starting point.23 For activities associated with 

filing TRI chemical reports, RBBM burden estimates include rule familiarization, reporter 

compliance determination, calculations and form completion, and recordkeeping. Similarly, for 

activities unrelated to form reporting (non-form burden) RBBM estimates include supplier 

notification, non-reporter compliance determination, and preparation and submission of petitions.

Figure 1 presents the equations of RBBM’s primary method: Steady State Total Burden 

Calculation. With RBBM’s calculation of form burden, the only variables/inputs required are total 

counts for Form R Chemicals and Form A Chemicals. The factors/constants of the equations 

include: 1) Nominal Form R unit burden, in units of burden hours per Form R Chemical and 2) 

A/R,24a model for the ratio of Form A (single-chemical)25 to Form R burden. 

As shown in Figure 1, multiplying the Nominal Form R unit burden by the number of Form R 

Chemicals provides an estimate of the total Form R burden. Similarly, multiplying the Form A 

unit burden (formulated as the product of A/R and Nominal Form R unit burden) by the number of 

Form A Chemicals provides an estimate of the total Form A burden.

 

22 For references on methodology development, see RBBM Reference Document (Docket #EPA-HQ-OEI-2010-

0835), EPA, 2011. 

23At the time of transition (the start of the 2008 ICR) the comparison between totals is exact. Later, in an interim spotcheck (April 2010), totals were within 2%. 

24 In A/R, Form A unit burden is derived using the activities associated with the subset of elements from Form R that a 

reporter would complete in order to determine TRI reporting eligibility and file a Form A, ensuring internal 

consistency. For further details, see RBBM Reference Document (Docket #EPA-HQ-OEI-2010-0835), EPA, 2011.

25 Although Form A permits multiple chemical reports on the same form (on average 2.29 Chemicals per Form A), for 

purposes of methods development and modeling, EPA works with chemical counts, referring to “Form R Chemicals” 

and “Form A Chemicals.”
2/6/14

 

29

EPA considers the burden estimates it uses to be average values for the reporting community 

overall. As with any average, some facilities will be above the average, and others will be below 

it. Large, complex facilities may require more than the average time to comply; however, many 

other facilities subject to the rule are not large or complex. Overall, EPA considers the TRI 

Program burden estimates to be reasonably representative of the reporting community overall, 

on average.

Form R and Form A Respondent Requirements 

Facilities engage in a number of activities to comply with the EPCRA §313 reporting 

requirements. These activities can be divided into two distinct groups: Form Activities, 

consisting of rule familiarization, reporter compliance determination, calculations and form 

completion, and recordkeeping and submission; and Non-Form Activities consisting of supplier 

notification, non-reporter compliance determination, and petitions. Section 4(b)(ii) presents a 

detailed description of these activities.

Form Activities

 Rule Familiarization

 Reporter Compliance Determination 

 Calculations and Form Completion

 Recordkeeping and Submission

Non-Form Activities

 Supplier Notification

 Non-Reporter Compliance Determination

 Petitions

Note that for burden unrelated to reporting on a Form R or Form A (Non-Form Activities), 

the RBBM simplifies calculations by holding all of these values at a constant level, as 

estimated in the 2008 ICR Renewal.26

Updating Nominal Form R and Form A Unit Burdens 

As discussed above, since the last ICR Renewal, five changes to the reporting requirements have 

occurred via rulemakings. Two of these rulemakings, tribal reporting and NAICS code updates, 

create no additional steady state programmatic burden. Due to the electronic reporting rule, a 

small number of facilities currently filing non-trade secret reports via paper will have to switch 

to electronic submission. The economic analysis supporting the rulemaking presents estimates 

of burden under a range of possible scenarios for this transition. Given the very small number of 

facilities potentially experiencing burden and the minor compliance costs, distributing this 

burden/cost across the full reporting universe results in negligible incremental per facility 

burden/cost. Therefore, at the margin, the electronic reporting rule does not constitute enough 

change to estimate additional burden. The lifting of the stay on hydrogen sulfide resulted in the 

reporting of 487 hydrogen sulfide reports (464 Form Rs and 23 Form As) by 484 facilities in RY

2012. The baseline for this ICR Renewal captures these reports. EPA estimates that the oNitrotoluene rule will increase the number of first time reporting facilities by 1 and the total 

number of Form Rs and Form As submitted by 17 and 5, respectively. The unit burdens 

associated with filling out Form R and Form A, however, remain unchanged. Section 6(d) 

discusses the anticipated change in the number of Form Rs and Form As filed.

Additionally, EPA is proposing to revise data elements for Form Rs and Form As that would 

improve the consistency and utility of TRI data. However, EPA estimates that the revision of 

data elements will have no measurable impact on Form R and Form A burden. 

The following discussion explains how changes from rulemakings since the last ICR affect form 

unit burdens and how these changes will negligibly affect form unit burdens if EPA finalizes the 

proposed form revisions (analysis is based on RY 2012 data with updates to reflect the estimated 

additional reporting resulting from the Addition of o-Nitrotoluene rule).

Addition of o-Nitrotoluene 

On November 7, 2013, EPA added o-Nitrotoluene to the list of toxic chemicals subject to 

reporting under section 313 of the Emergency Planning and Community Right-to-Know Act 

(EPCRA) of 1986 and section 6607 of the Pollution Prevention Act (PPA) of 1990. EPA 

determined it meets the criteria for listing under EPCRA section 313(d)(2)(B) because the 

National Toxicology Program reasonably anticipates it to be a human carcinogen. Further, EPA 

estimates that facilities currently manufacture, process or otherwise use this chemical above TRI 

thresholds and therefore would file TRI reports. EPA expects facilities to file Form Rs and Form 

As on o-Nitrotoluene. The total number of additional TRI reports expected due to the rule is 17 

Form Rs and 5 Form As, and the number of new facilities reporting to TRI is one. Note that this 

rule does not affect the value of the Nominal Form R unit burden.

Revised Data Elements

EPA is proposing several revisions to Form R and Form A. As mentioned above, these revisions 

will contribute to the standardization of responses and enhancement of data utility. Specifically, 

EPA is proposing: 

 to add an optional extension to all phone numbers to allow facility representatives to 

provide the extension needed for a direct connection. Because this is an optional question, 

by convention, no regulatory burden is imposed on facilities with its addition.

 to add an optional field to allow facilities to indicate of the section of the water body that 

received the surface water discharges reported in Section 5.3. Specifically, facilities will be 

able to provide “reach codes,” which are unique codes that identify a continuous piece of 

surface water with similar hydrologic characteristics. Because this is an optional question, 

by convention, no regulatory burden is imposed on facilities with its addition.

 to move the header “5.5 Disposal to land on-site” to precede Sections 5.4 and 5.5 on Form 

R so that it covers both 5.4 and 5.5. Re-word 5.4.1 and 5.4.2 to fit under the new header as 

follows: Section 5.4-5.5: Disposal to land on-site, Section 5.4.1: Class 1 Underground 

Injection Wells, Section 5.4.2 Class II-V Underground Injection Wells. These changes 

serve only to clarify what is already being reported in these sections and thus do not 

impose any additional regulatory burden.

 to provide the heading, “Production-related waste managed” for Sections 8.1-8.7 and relabel Section 8.8 “Non-production-related waste managed.” These changes serve only to 
2/6/14

 

32

clarify what is already being reported in these sections and thus do not impose any 

additional regulatory burden.

 to add checkboxes to indicate whether a facility has provided a “Production Ratio” or 

“Activity Ratio” in Section 8.9. The existing form already includes a field to submit one of 

these two ratios, so facilities must already decide which type of ratio to report and then 

report the calculated value. The only change is that facilities must now also indicate which 

type of ratio they selected. No additional regulatory burden is imposed as facilities already 

possess this information and are just identifying which ratio they are reporting. 

 to add a new column (d) in Section 8.10 where facilities can provide a percentage range 

indicating the estimated annual reduction in chemical waste generation associated with a 

given source reduction activity. Because this is an optional question, by convention, it 

imposes no regulatory burden on facilities with its addition. Note that while this change 

may create additional burden for facilities choosing to report the information, requesting 

range reporting, rather than the development of a point estimate, minimizes the burden on 

facilities.

 to provide optional barrier codes in Section 8.11 that facilities can use to indicate why they 

could not implement any source reduction activities during the reporting year.

 to allow a facility to categorize optional free-text information entered in Sections 8.11 and 

9.1 by selecting from a list of topics provided in TRI-MEweb. Because this is an optional 

question, by convention, it imposes no regulatory burden on facilities with its addition. 

Note that while this change may create additional burden for facilities choosing to report 

the information, facilities need only read from a short list of topics and select one.

The changes proposed, along with their contributions to the forms and estimated additional 

burden are presented in Table 4.

Any given facility may file only Form Rs, only Form As, or a combination of Form Rs and 

Form As. Table 6 provides more details on the distribution of reporting by form type among 

facilities. Note also that for a given Form A filing (where multiple chemicals can be reported on 

a single form), the average number of chemicals reported is 2.29. Overall, each facility reports 

an average of 3.80 chemicals (Rs and As), with 11.3% of all chemicals filed via Form As.

with updates to reflect additional reporting due to the Addition of o-Nitrotoluene Rule.

2) Approximately 73% percent of affected facilities filed three or fewer Form R chemicals in RY 2012. The most 

common number of Form R chemicals reported is one. 

3) Approximately 94% percent of affected facilities filed two or fewer Form A chemicals in RY 2012. The most 

common number of Form A chemicals reported is zero (by facilities reporting Form A, the most common number of 

Form A chemicals reported is one).

4) The average number of Form A chemicals per Form A is 2.29.

5) The total average number of chemicals per facility across all types of facilities filing the form (Form A only, Form R 

only, Both Form R and Form A) is calculated by dividing the total number of chemicals by the total number of unique 

facilities.

Table 7 presents the annual estimated burden hours for the overall average conditions. These 

estimates represent the burden on a "typical" facility as defined by the facility filing the 

average number of chemicals (as represented by overall averages). As shown in Table 6, there 

are a variety of patterns for Form R and Form A Chemical filings by facility. Section 6(d) 

discusses the total annual burden to all facilities.

6(b) Estimating Respondent Costs

EPA calculates the steady state total cost to respondents based on the time needed to complete the 

activities listed in Section 6(a) and the weighted average wage rate (WAWR) which is the average 

loaded cost for a mix of managerial, technical, and clerical labor (in proportions of .03, .89, and 

.08, respectively) per hour of TRI reporter burden.27 There are no specific capital and operation 

and maintenance costs associated directly with this information collection activity. There may be 

some small additional costs for mailing and supplies, although with the recent promulgation of the 

electronic reporting rule, these costs are minimized. Section 6(d) discusses total annual costs for 

all facilities.

(i) Estimating Labor Costs

EPA estimates labor burden for three separate labor categories (management, technical, and 

clerical) across multiple activities; it is necessary to obtain wage rates for each labor category in 

order to estimate labor costs and compute WAWR, as shown in Table 8. 

 

27

 For the derivation and justification of the WAWR, see RBBM Reference Document (Docket #EPA-HQ-OEI-2010-

0835), EPA, 2011.

Note that these estimates assume non-form burden to be a constant at 825,517 hours with an 

associated cost of $42,580,167. The components of this burden are:

 Petitions – 925 hours

 Supplier Notification – 89,616 hours

 Non Reporters’ Compliance Determination – 734,976 hours

EPA estimates the total cost associated with non-form burden by multiplying this constant by the 

WAWR (see Section 6(d) for total respondent cost associated with the TRI Program).

This section estimates the burden and costs to EPA to process Form R and Form A reports based 

on information characterizing the resources used in previous years. EPA incurs burden and costs 

for three categories of activities: RFI and Compliance Assistance; TRI Reporting Software and 

Related Data Collection and Exchange; and Data Processing. Table 10 outlines these activities

in detail.

a E-mail communication with TRI Data Processing Center, January 10, 2014.

b Based on actual headcounts for RY2012.

The estimated Data Processing costs include fixed costs (overhead) and variable costs, which 

depend on the number and type of form submissions. The cost of processing TRI forms is 

approximately $27.86 per chemical for paper submissions and $6.05 per chemical for TRI-MEweb

submissions.28 Based on reporting year 2012, the total annual Agency cost for items, as shown in 

Table 11, is $4,630,771. Note that, due to the Electronic Reporting Rule, EPA expects that data 

processing costs will decrease, however, the magnitude of this decrease is unclear at this time. 

While it will no longer be necessary for EPA to key the data from paper forms, TRI-MEweb 

submissions sometimes require other manual steps (i.e., facility reconciliation). In addition, in the 

first year of mandatory electronic reporting, EPA has developed a process to reject (return) any 

paper forms submitted.

6(d) Estimating the Respondent Universe and Total Burden and Costs

Estimated Total Annual Burden for All Respondents

This section presents the total annual burden hours for all respondents, incorporating both 

form and non-form burden (see detailed bases in Section 6(a)). EPA uses the Steady State 

Total Burden method to estimate the total burden hours for all respondents under this ICR, as 

depicted in Figure 1. EPA calculates Form R burden and Form A burden using unit burdens 

and single-chemical form counts; non-Form burden is a constant. These three burden 

components sum to calculate the Steady State Total Burden. Table 12 shows the assumed 

universe of TRI facilities and forms for both Form Rs and Form As for this ICR Renewal.

Notes: 

1) Facilities filed 25 Form As for lead in RY 2012, likely associated with lead in stainless steel, brass or bronze alloys 

which are not excluded from Form A eligibility.

2) The total unique number of facilities reporting in RY 2012 was 21,025 (see footnote 4). The sum of facilities 

reporting Form R and Form A above does not equal 21,025 because some facilities report both Form Rs and Form As 

(see Table 7). The average number of Form R chemicals per facility is 3.37. The average number of Form A chemicals 

per facility is 0.43. The average number of chemicals per facility is 3.80. The average number of Form A chemicals 

per Form A is 2.29.

3) The number of Form As is equal to the number of facilities reporting Form A chemicals (3,931). The number of 

chemicals per Form A is 2.29 (9,000 Form A chemicals ÷ 3,931 Form As). Note that burden per Form A chemical is 

the key unit for tracking burden associated with a Form A, and that the conversion to number of Form As (i.e., number 

of Form A responses) is done to satisfy certain burden accounting and reporting requirements.

4) The universe includes the modeled number of Form Rs, Form As, and facilities estimated to report under the 

Addition of the o-Nitrotoluene Rule. It is estimated that under the rule, 1 new facility will be added to the regulated 

community and an additional 17 non-PBT chemical Form Rs and 5 Form As will be submitted.

Estimated Total Annual Cost for All Respondents

EPA determined the total annual reporting cost for all respondent facilities by multiplying the

WAWR by the steady state total burden. Table 14 presents the total annual reporting cost for 

Form R and Form A.

6(e) Bottom-Line Burden Hours and Cost Tables

This section presents the total burden and cost to the regulated industry to comply with the 

information collection requirements under EPCRA §313 and under PPA §6607, as well as the 

cost to EPA to process Form R and Form As annually.

a The total number of facilities reporting (21,025) is not equal to the sum of Form R and Form A respondents as some 

facilities may file both Form Rs and Form As.

b The average number of responses per respondent is 3.56.

c The basis for the estimates of facilities and responses is derived from RY 2012 TRI reporting with updates to reflect the 

estimated impacts of the Addition of o-Nitrotoluene Rule, published November 7, 2013.

(ii) The Agency Tally

EPA estimates the total annual program burden to the Agency to be $4.63 million, and 5.2 FTEs. 

These costs reflect the burden to conduct the EPA activities described above. 

(iii) Variations in the Annual Bottom Line

EPA does not expect significant variation in the annual respondent reporting/recordkeeping burden 

and cost over the course of the ICR approval period.

6(f) Reasons for Change in Burden

Change in burden estimates since OMB approved of the combined Form R/A ICR on October 14, 

2011 include:29

 the lifting of the Administrative Stay of the Toxics Release Inventory reporting 

requirements for hydrogen sulfide on October 17, 2011. EPA received the first 

submissions for hydrogen sulfide for reporting year 2012; the total number of form 

submissions used to calculate the overall program burden therefore includes these 

hydrogen sulfide submissions. 

 the Addition of o-Nitrotoluene Rule, which the Federal Register included in its publication 

on November 7, 2013. EPA estimates this rule will increase the number of reporting 

facilities by 1 and the number of Form Rs and Form As submitted by 17 and 5 

respectively, with an associated ongoing steady state burden increase of 717 hours. 

 

29 As noted in Section 6(a) given the very small number of facilities potentially experiencing burden and the minor 

compliance costs due to the electronic reporting rule, distributing this burden/cost across the full reporting universe 

results in negligible incremental per facility burden/cost. Therefore, at the margin, the electronic reporting rule does 

not constitute enough change to estimate additional burden.
2/6/14

 

42

Over the last few years, there has been a slight increase in the number of facilities reporting to 

TRI. Based on the latest data for RY 2012 with updates to reflect the estimated burden due to the 

addition of o-Nitrotoluene, EPA now estimates the total number of combined Form R and Form 

A responses to be 74,869, the associated total annual burden hours to be 3,555,998, and the 

annual cost to be $183,418,361. Further, the TRI program is proposing to revise data elements 

for the reporting forms. EPA estimates that the revised data elements will have a negligible 

impact on form burden.

Since the ICR approval on October 14, 2011, the increase in the estimate of total burden of 39,530 

hours (exclusive of o-Nitrotoluene reports which have not yet been received) primarily resulted 

from the filing of approximately 1,124 more forms in RY 2012 than was projected in the 2011 

ICR Renewal (based on RY 2009 data). Refer to Figure 2 and Table 17 for background 

information on the chronology of both TRI rulemakings and ICR renewals which outlines changes 

that have occurred due to rulemaking.

6(g) Burden Statement (To appear on Collection Instrument)

EPA estimates the annual public burden for form calculations such as rule familiarization, 

compliance determination, calculations and form completion, and recordkeeping, which is 

approved under OMB Control No. 2025-0009, to average 35.70516 hours per response for a 

facility filing a Form R and 21.95867 hours for a facility filing a Form A for one chemical. 

There is additional non-form burden associated with non-reporter compliance determination, 

petitions and supplier notification. 

Burden is defined as the total time, effort, or financial resources expended by persons to 

generate, maintain, retain, or disclose or provide information to or for a federal agency. This 

includes the time needed to review instructions; develop, acquire, install, and utilize technology 

and systems for the purposes of collecting, validating, and verifying information, processing and 

maintaining information, and disclosing and providing information; adjust the existing ways to 

comply with any previously applicable instructions and requirements; train personnel to be able 

to respond to a collection of information; search data sources; complete and review the 

collection of information; and transmit or otherwise disclose the information. 

An agency may not conduct or sponsor, and a person does not have to respond to, a collection of 

information unless it displays a currently valid OMB control number. The OMB control 

numbers for EPA's regulations are listed in 40 CFR Part 9 and 48 CFR Chapter 15.

To comment on the Agency's need for this information, the accuracy of the provided burden 

estimates, and any suggested methods for minimizing respondent burden, including the use of 

automated collection techniques, EPA has established a public docket for this ICR under Docket 

ID No. EPA-HQ-OEI-2013-0803 which is available for online viewing at www.regulations.gov,
