SUPPORTING STATEMENT FOR THE
INFORMATION COLLECTION REQUIREMENTS IN
THE 1,2-DIBROMO-3-CHLOROPROPANE (DBCP) STANDARD
(29 CFR 1910.1044) OMB CONTROL NO. 1218-0101 (June 2022)
This ICR is the extension of a currently approved data collection.
A. JUSTIFICATION
1.

Explain the circumstances that make the collection of information necessary.
Identify any legal or administrative requirements that necessitate the collection.
Attach a copy of the appropriate section of each statute and regulation mandating
or authorizing the collection of information.

The Occupational Safety and Health Administration (OSHA) cites sections of the Occupational Safety and
Health Act (OSH Act) to justify collecting information. Sections of the Occupational Safety and Health
Act may be found at 29 U.S.C. Chapter 15 – Occupational Safety and Health
https://www.law.cornell.edu/uscode/text/29/chapter-15

The main purpose of the Occupational Safety and Health Act (“OSH Act” or Act) is to. . . assure
so far as possible every working man and woman in the Nation safe and healthful working
conditions and to preserve our human resources (29 U.S.C. 651). As one means in achieving this
objective, the OSH Act specifically authorizes the development and promulgation of
occupational safety and health standards (29 U.S.C. 651) to ensure that workers will be furnished
employment and a place of employment free from recognized hazards that are causing or likely
to cause death or serious physical harm.
To protect worker health, the OSH Act authorizes the Occupational Safety and Health
Administration (“OSHA” or “Agency”) to develop standards that provide for “monitoring or
measuring worker exposure” to occupational hazards and “prescribe the type and frequency of
medical examinations and other tests which shall be made available [by the employer] to workers
exposed to such hazards…to most effectively determine whether the health of such workers is
adversely affected by such exposure” (29 U.S.C. 655). Moreover, the Act directs OSHA to
“issue regulations requiring employers to main accurate records of worker exposures to
potentially toxic materials or other harmful physical agents which are required to be monitored
and measured …” (29 U.S.C. 657). In addition, the OSH Act mandates that “[e]ach employer
shall make, keep and preserve, and make available to the Secretary [of Labor] …such records
regarding [the employer’s] activities relating to this Act as the Secretary …may prescribe by
1

1,2-Dibromo-3-Chloropropane Standard
OMB Control Number 1218-0101
Expiration Date: 8-31-2022

regulation as necessary or appropriate for the enforcement of this Act …” (29 U.S.C. 657).
For toxic substances, the OSH Act contains specific statutory language. Thus, as appropriate,
health standards must include provisions for monitoring and measuring worker exposure,
medical examinations and other tests, control and other technological procedures, suitable
protective equipment, labels and other appropriate forms of warning, and precautions for safe use
or exposure (29 U.S.C. 655). In addition, the OSH Act specifically mandates issuing regulations
requiring employers to maintain accurate records of worker exposures to potentially toxic
materials or other harmful physical agents that are required to be monitored and measured, and
further requires that workers exposed to concentrations over prescribed limits be notified of this
fact, and of the corrective action being taken (29 U.S.C. 657).
Using the statutory authority granted to it by the OSH Act, the Occupational Safety and Health
Administration (OSHA) published a health standard governing worker exposure to 1,2-dibromo3-chloropropane (DBCP) in 1978 (29 CFR 1910.1044 1). OSHA published the DBCP Standard
(also referred to as Athe Standard) based on scientific studies demonstrating that DBCP is a
potent carcinogen in experimental animals and causes sterility and infertility in humans. OSHA
limited exposure to DBCP to the lowest feasible level, i.e., an 8-hour time weighted average
exposure limit of 1 part of DBCP per billion parts of air (1 ppb); this exposure level (1 ppb) is
the permissible exposure limit (PEL). The 1979 TSCA (Toxic Substances Control Act)
Inventory identified 3 companies producing 1,000 lbs of DBCP in 1977, and 1 DBCP importer,
but provided no information on import volumes.
The Environmental Protection Agency (EPA) registered DBCP as a soil fumigant for controlling
nematodes during growth of field crops, vegetables, fruits and nuts, greenhouse and nursery
crops, and turf. In 1977, the EPA suspended all registration of DBCP-based end-use products,
except fumigants for Hawaiian pineapples; EPA revoked this exception in 1985. According to
the Eleventh Report on Carcinogens January 31, 2005, compiled by the National Toxicology
Program 2 no current production data are available for DBCP. 3 However, OSHA continues to

Note that the DBCP Standards for Shipyards (29 CFR 1915.1044) and Construction (29 CFR 1926.1144)
incorporate by reference the General Industry DBCP Standard (29 CFR 1910.1044).

1,2-Dibromo-3-chloropropane (DBCP) was used in the past as a soil fumigant and nematicide on crops; it
is no longer used except as an intermediate in chemical synthesis. Acute (short-term) exposure to DBCP in humans’
results in moderate depression of the central nervous system (CNS) and pulmonary congestion from inhalation, and
gastrointestinal distress and pulmonary edema from oral exposure. Chronic (long-term) exposure to DBCP in
humans causes male reproductive effects, such as decreased sperm counts. Testicular effects and decreased sperm

request approval for the collection of information requirements contained in the Standard to
ensure continued compliance should an employer use DBCP in the future.
The purpose of DBCP Standard is to provide protection for workers from the adverse health
effects caused by occupational exposure to DBCP. To ensure that workers are receiving this
protection, the Standard requires employers to provide OSHA with access to various records.
Items 2 and 12 below list and fully discuss the specific information collection requirements
specified by the Standard.
2.

Indicate how, by whom, and for what purpose the information is to be used. Except
for a new collection, indicate the actual use the agency has made of the information
received from the current collection.

Exposure Monitoring (§1910.1044(f))
Employers must perform initial monitoring to determine the extent of DBCP exposure in their
workplaces. 4 Initial monitoring enables employers to identify areas of operation that may
require additional efforts to reduce worker exposure to DBCP and, therefore, helps them come
into compliance with the Standard. Initial monitoring results also assist employers in
determining the need for engineering controls, instituting or modifying work practices, and
selecting appropriate respiratory protection to prevent workers from overexposure to DBCP. If
the initial monitoring finds that DBCP is at or below the PEL, the employer must repeat these
measurements at least every 6 months. If the initial monitoring indicates that DBCP exposure is
in excess of the PEL, the employer must repeat these measurements at least quarterly; areas in
which worker exposures exceed the PEL are Aregulated areas. Quarterly monitoring must
continue until two consecutive measurements, taken at least 7 days apart, are below the PEL,
after which the employer must monitor at least every 6 months. Periodic monitoring allows
employers to evaluate the effectiveness of exposure-control methods. In addition, these
measurements remind both the employer and workers of the continuing need to protect against
the hazards that could result from a worker’s overexposure to DBCP. Periodic monitoring also
informs the physician responsible for medical surveillance of the existence and extent of a
potential source of occupational disease.
counts were observed in animals chronically exposed to DBCP by inhalation. Available human data on DBCP and
cancer are inadequate. High incidences of tumors of the nasal tract, tongue, adrenal cortex, and lungs of rodents
were reported in a National Toxicology Program (NTP) inhalation study. EPA has classified DBCP as a Group B2,
probable human carcinogen. https://www.epa.gov/sites/production/files/2016-09/documents/1-2-dibromo-3chloropropane.pdf
4

Initial and periodic monitoring must be representative of each worker exposure to DBCP.

3

1,2-Dibromo-3-Chloropropane Standard
OMB Control Number 1218-0101
Expiration Date: 8-31-2022

Employers must perform additional monitoring if any change occurs in production, processes,
controls, or personnel that may result in new or increased worker exposures to DBCP, or if the
employer reasonably suspects that any other condition could result in such exposure. Additional
monitoring ensures that the workplace is safe or alerts the employer to increase the worker
protection.
Paragraph 1910.1044(f)(5) requires that employers must inform each worker of their exposuremonitoring results within 15 working days after receiving these results. Employers may notify
workers either individually in writing or by posting the monitoring results in an appropriate
location that is accessible to the workers. In addition, if the exposure-monitoring results show
that a worker’s exposure exceeds the PEL, the employer must inform the exposed worker of the
corrective action the employer is taking to prevent such overexposure.
Notification provides workers with information about the efforts the employer is taking to lower
their DBCP exposures and to furnish them with a safe and healthful workplace in accordance
with section 8(c)(3) of the OSH Act.
Written Compliance Program (§1910.1044(g)(2))
Employers must establish and implement a written program to reduce worker DBCP exposure to
or below the PEL using engineering and work-practice controls. This program must also include
a detailed schedule for developing and implementing engineering and work-practice controls.
Employers must, at least, review and/or revise the compliance plan at least annually, to describe
the programs current status.
This requirement commits the employer to evaluating worker exposure and establishing an
organized and complete program for reducing worker exposures to or below the PEL. Updating
the program serves to remind employers to implement and maintain the exposure-control
methods required by the Standard.
Respiratory Program (§1910.1044(h)(2))
If employers require respirator use, they must establish a respiratory-protection program in
accordance with 29 CFR 1910.134, paragraphs (b) through (d) (except (d)(1)(iii)), and (f)
through (m)). Paragraph (c) of 29 CFR 1910.134 requires the employer to develop and
implement a written respiratory-protection program with worksite-specific procedures and
elements for respirator use. The purpose of these requirements is to ensure that employers
establish a standardized procedure for selecting, using, and maintaining respirators for each
4

1,2-Dibromo-3-Chloropropane Standard
OMB Control Number 1218-0101
Expiration Date: 8-31-2022

workplace requiring respirator use. Developing written procedures ensures that employers
implement a respirator program that meets the needs of their workers. OSHA incurs the burden
hours and costs resulting from these program requirements under the ICR for OSHA’s
Respiratory Protection Standard (29 CFR 1910.134), OMB Control Number 1218-0099.
Written Emergency-Situation Plan (§1910.1044(i)(1))
The employers must develop and implement a written plan describing the emergency response to
accidental releases of DBCP. This plan provides workers with personal-protection and
evacuation information that minimizes their exposure to DBCP in these situations.
Removal and Storage of Protective Devices and Clothing (§1910.1044(j)(2)(v))
Containers of DBCP-contaminated protective devices or work clothing which are to be taken out
of change rooms or the workplace for cleaning, maintenance or disposal shall bear labels with
the following information:
CONTAMINATED WITH 1,2-Dibromo-3-chloropropane (DBCP), MAY CAUSE CANCER.
Notifying the Laundry Personnel (§1910.1044(j)(3)(ii))
The employer must notify any person who launders or cleans DBCP-contaminated protective
clothing or equipment of the potentially harmful effects of exposure to DBCP. This information
allows such personnel to protect themselves from DBCP exposure.
Medical Surveillance (§1910.1044(m))
General (§1910.1044(m)(1), (m)(2), and (m)(3))
The Standard requires employers to provide a medical surveillance program for workers who
work in regulated areas and workers exposed to DBCP during emergency situations. Employers
must provide workers with medical examinations for workers: When initially assigned to a
regulated area; annually thereafter for as long as they are assigned to a regulated area; and if they
develop signs or symptoms commonly associated with exposure to DBCP. The results of medical
examinations administered under this program must be documented and maintained.
Documentation and maintenance of medical-examination results provide a continuous record of
worker health. Physicians use these records to determine the extent to which workers have
experienced DBCP-related health effects since their last examination. Further, if symptoms of
5

1,2-Dibromo-3-Chloropropane Standard
OMB Control Number 1218-0101
Expiration Date: 8-31-2022

organic damage appear, the physician often needs information about a worker’s previous medical
conditions to make an accurate diagnosis of the new condition, ascertain its apparent cause, and
identify a course of treatment. Medical records also permit workers to determine whether or not
they need treatment, or to evaluate the effectiveness of their employer's exposure-reduction
program.
Information Provided to the Physician (§1910.1044(m)(4))
The employer must provide the physician who examines each worker with the following
information: A copy of the Standard, including the appendices; a description of the workers
duties as they relate to the workers DBCP exposure; the level of DBCP exposure to which the
worker is exposed; and a description of personal protective equipment that the worker uses or
will use.
Making the required information available to the physician will aid in the evaluation of the
workers health and fitness for specific job assignments involving DBCP exposure. As noted
earlier, if symptoms of organic damage appear, the physician often needs information about a
worker’s previous medical conditions to make an accurate diagnosis of the new condition, to
ascertain its apparent cause, and to identify the course of treatment required. Medical records
also ensure that workers can determine the need for treatment or other interventions, and to
evaluate the effectiveness of the employer's exposure-reduction program.
Physician's Written Opinion (§1910.1044(m)(5))
Employers must provide a copy of the physician's written opinion to each worker. This opinion
must contain the following information: The results of the medical examination; the physicians
opinion indicating if the worker has any medical conditions that may place the worker at
increased risk of material impairment to health from continued DBCP exposure; and any
recommended limitations on the worker's DBCP exposure or on the use of protective clothing or
equipment such as respirators. This provision requires the employer to instruct the physician not
to reveal certain information to the employer. The purpose of requiring the employer to obtain a
written opinion from the physician is to provide the employer with medical information to aid in
determining the initial placement of workers, and to assess a worker's ability to use protective
clothing and equipment. The physician's opinion also provides the employer with information
about whether or not the worker has a condition indicating overexposure to DBCP. The
requirement that a physician's opinion be written will properly memorialize the information for
later retrieval if needed. The requirement to provide workers with a copy of the physicians
written opinion will ensure that they are informed of the results of the medical examination so
that they can assist in determining the need for, and evaluate the effectiveness of, treatment or
6

1,2-Dibromo-3-Chloropropane Standard
OMB Control Number 1218-0101
Expiration Date: 8-31-2022

other interventions.
Worker Information and Training (§1910.1044(n))
Training is essential to inform workers of the hazards to which they are exposed, and to provide
them with information they can use to minimize the health hazards of DBCP. Having a copy of
the Standard and its appendices available serves to explain and reinforce the information
presented to workers on signs, labels and safety data sheets; these documents (signs, labels and
safety data sheets) will be useful and effective to workers in understanding the health hazards of
DBCP and assuring that they are aware of the actions they can take to avoid or minimize DBCP
exposure. However, the requirements that employers provide training materials to workers under
§1910.1044(n) are not considered to be a collection of information. OSHA is not taking burden
for this activity under Item 12 of this Supporting Statement.
Signs and Labels (§1910.1044(o))
(o) Communication of hazards—(1) Hazard communication—general. (i) Chemical
manufacturers, importers, distributors and employers shall comply with all requirements of the
Hazard Communication Standard (HCS) (§1910.1200) for DBCP. Labels. (1) Where DBCP or
products containing DBCP are, sold, distributed or otherwise leave the employer’s workplace
bearing appropriate labels required by EPA under the regulations in 40 CFR Part 162, the labels
required by this paragraph, (0)(3) need not be affixed.
Signs (§1910.1044(o)(2)(i)
The employer shall post signs to clearly indicate all regulated areas. Posting warning signs
serves to warn workers that they are in or near a regulated area. Such signs warn workers that
they can enter a regulated area only if they have authority to do so and a specific need exists to
enter the area. Warning signs also supplement the training workers receive under the Standard.
Warning labels inform downstream employers and workers of the hazards associated with
exposure to DBCP and DBCP-containing products, alert them to prevent exposure to the
contaminants, and, if such exposure is unavoidable, provide notice to downstream employers that
they must comply with the requirements specified by the Standard.
Recordkeeping (§1910.1044(p))
Exposure-Monitoring and Medical-Surveillance Records (§§1910.1044(p)(1) and (p)(2))

7

1,2-Dibromo-3-Chloropropane Standard
OMB Control Number 1218-0101
Expiration Date: 8-31-2022

Employers must establish and maintain exposure-monitoring records and medical-surveillance
records. This requirement provides both employers and workers with access to useful
information. The exposure-monitoring and medical-surveillance records required by the
Standard assist workers and their physicians in determining the need for treatment or other
interventions as a result of the workers exposure to DBCP. The information also will enable the
employers to better ensure that workers are not being overexposed to DBCP; such information
may alert the employer that steps must be taken to reduce DBCP exposures.
Employers must maintain exposure-monitoring and medical-surveillance records for at least 40
years, or the duration of employment plus 20 years, whichever is longer. OSHA requires
maintenance of these records for this extended period because of the long latency associated with
the development of DBCP-related cancers, sterility, and infertility.
Availability (§1910.1044(p)(3))
Employers must provide exposure-monitoring and medical-surveillance records to workers and
their designated representatives on request.
Workers and their designated representatives use exposure-monitoring and medical-surveillance
records to assess worker medical status over the course of employment, to evaluate the
effectiveness of the employer's exposure-reduction program, and for other reasons.
3.

Describe whether, and to what extent, the collection of information involves the use
of automated, electronic, mechanical, or other technological collection techniques or
other forms of information technology, e.g., permitting electronic submission of
responses, and the basis for the decision for adopting this means of collection. Also
describe any consideration of using information technology to reduce burden.

Employers may use improved information technology when making, keeping, and preserving the
required records. The Standard is written in performance-oriented language, i.e., in terms of
what data to collect rather then how to collect the data.
4.

Describe efforts to identify duplication. Show specifically why any similar
information already available cannot be used or modified for use for the purposes
described in Item A.2. above.

The requirements to collected and maintain information are specific to each employer and
worker involved, and no other source or agency duplicates these requirements or can make the
required information available to OSHA (i.e., the required information is available only from
8

1,2-Dibromo-3-Chloropropane Standard
OMB Control Number 1218-0101
Expiration Date: 8-31-2022

employers).
5.

If the collection of information impacts small businesses or other small entities,
describe any methods used to minimize burden.

The burden of these requirements is an equal obligation for employers who have establishments
or operations in which exposures could occur. Because of the manner in which the standard is
written, the employer can choose to respond to this requirement in a way that is best suited to

9

1,2-Dibromo-3-Chloropropane Standard
OMB Control Number 1218-0101
Expiration Date: 8-31-2022

their work environment. The requirements are based on performance, and compliance is judged
accordingly. There are no set requirements for how the information is documented or
maintained.
6.

Describe the consequence to Federal program or policy activities if the collection is
not conducted or is conducted less frequently, as well as any technical or legal
obstacles to reducing burden.

The Agency believes that the information collection frequencies required by the Standard are the
minimum frequencies necessary to effectively monitor the exposure and health status of workers
exposed to DBCP, and thereby fulfill its mandate Ato assure so far as possible every working
man and woman in the Nation safe and healthful working conditions and to preserve our human
resources as specified by the OSH Act at 29 U.S.C. 651. Accordingly, if employers do not
perform the required information collections, or delay in providing this information, workers will
have an increased probability of developing cancer because of their DBCP exposures.
7.

Explain any special circumstances that would cause an information collection to be
conducted in a manner:
•

requiring respondents to report information to the agency more often than
quarterly; requiring respondents to prepare a written response to a
collection of information in fewer than 30 days after receipt of it;

•

requiring respondents to submit more than an original and two copies of any
document;

•

requiring respondents to retain records, other than health, medical,
government contract, grant-in-aid, or tax records for more than three years;

•

in connection with a statistical survey, that is not designed to produce valid
and reliable results that can be generalized to the universe of study;

•

requiring the use of a statistical data classification that has not been reviewed
and approved by OMB;

•

that includes a pledge of confidentiality that is not supported by authority
established in statute or regulation, that is not supported by disclosure and
data security policies that are consistent with the pledge, or which
10

1,2-Dibromo-3-Chloropropane Standard
OMB Control Number 1218-0101
Expiration Date: 8-31-2022

•

unnecessarily impedes sharing of data with other agencies for compatible
confidential use; or
requiring respondents to submit proprietary trade secret, or other
confidential information unless the agency can demonstrate that it has
instituted procedures to protect the information's confidentiality to the
extent permitted by law.

If exposure monitoring indicates that a worker has been exposed above the PEL, regardless of
whether or not respirators are used, employers must notify the worker individually in writing (or
by posting the results in an appropriate location) of the exposure-monitoring results, and the
steps being taken to reduce the exposure to within the PEL. This notification must be provided to
the worker within 15 working days.
Posting enhances the collective knowledge in the workplace of worker exposures, which in turn
enhances each worker’s understanding of his/her own exposure. Posting the results facilitates
other workers, their designated representatives, supervisor, and employers in becoming aware of
exposure levels within the workplace.
Employers must maintain exposure-monitoring and medical-surveillance records for at least 40
years, or the duration of employment plus 20 years, whichever is longer. OSHA requires
maintenance of these records for this extended period because of the long latency associated with
the development of DBCP-related cancers, sterility, and infertility.
8.

If applicable, provide a copy and identify the date and page number of publication
in the Federal Register of the agency's notice, required by 5 CFR 1320.8(d),
soliciting comments on the information collection prior to submission to OMB.
Summarize public comments received in response to that notice and describe
actions taken by the agency in response to these comments. Specifically address
comments received on cost and hour burden.
Describe efforts to consult with persons outside the agency to obtain their views on
the availability of data, frequency of collection, the clarity of instructions and
recordkeeping, disclosure, or reporting format (if any), and on the data elements to
be recorded, disclosed, or reported.
Consultation with representatives of those from whom information is to be obtained
or those who must compile records should occur at least once every 3 years -- even if
the collection of information activity is the same as in prior periods. There may be
circumstances that may preclude consultation in a specific situation. These
11

1,2-Dibromo-3-Chloropropane Standard
OMB Control Number 1218-0101
Expiration Date: 8-31-2022

circumstances should be explained.
As required by the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 506(c)(2)(A)), OSHA
published a notice in the Federal Register on May 2, 2022 soliciting comments on its proposal to
extend the Office of Management and Budget’s (OMB) approval of the information collection
requirements specified in the 1,2-Dibromo-3-Chloropropane (DBCP) (29 CFR 1910.1044),
(Docket No. OSHA-2012-0010). This notice is part of a preclearance consultation program that
provides interested parties the opportunity to comment on OSHA’s request for an extension by
OMB of previous approval of the information collection requirements found in the above
Standard. The Agency did not receive any substantive comments submitted in response to this
notice.
9.

Explain any decision to provide any payment or gift to respondents, other than
remuneration of contractors or grantees.

The Agency will provide no payments or gifts to the respondents.
10.

Describe any assurance of confidentiality provided to respondents and the basis for
the assurance in statute, regulation, or agency policy.

To ensure that the personal information contained in medical-surveillance records remains
confidential, OSHA developed 29 CFR 1913.10 to regulate access to these records.
11.

Provide additional justification for any questions of a sensitive nature, such as
sexual behavior and attitudes, religious beliefs, and other matters that are
commonly considered private. This justification should include the reasons why the
agency considers the questions necessary, the specific uses to be made of the
information, the explanation to be given to persons form whom the information is
requested, and any steps to be taken to obtain their consent.

None of the provisions in the Standard require sensitive information.

12

1,2-Dibromo-3-Chloropropane Standard
OMB Control Number 1218-0101

12.

Provide estimates of the hour burden of the collection of information. The
statement should:
•

Indicate the number of respondents, frequency of response, annual hour
burden, and an explanation of how the burden was estimated. Unless
directed to do so, agencies should not conduct special surveys to obtain
information on which to base hour burden estimates. Consultation with a
sample (fewer than 10) of potential respondents is desirable. If the hour
burden on respondents is expected to vary widely because of differences in
activity, size, or complexity, show the range of estimated hour burden, and
explain the reasons for the variance. Generally, estimates should not include
burden hours for customary and usual business practices.

•

If this request for approval covers more than one form, provide separate
hour burden estimates for each form.

•

Provide estimates of annualized cost to respondents for the hour burdens for
collections of information, identifying and using appropriate wage rate
categories. The cost of contracting out or paying outside parties for
information collection activities should not be included here. Instead, this
cost should be included in Item 14.

After extensive research, OSHA found no U.S. employer who currently produces DBCP or
DBCP-based end-use products, most likely because the EPA registration suspension for this
substance remains in effect (see discussion under Item 1 above); therefore, no cost or time
burdens accrue to employers under the Standard. The Agency requests one hour for OMB to
approve the information collection provisions of the Standard so that it can enforce the
paperwork requirements of the Standard if EPA lifts the suspension or technology develops new
applications for DBCP. The Standards paperwork requirements are:

13.

Provide an estimate of the total annual cost burden to respondents or recordkeepers
resulting from the collection of information. (Do not include the cost of any hour
burden shown in Items 12 and 14).
•

The cost estimate should be split into two components: (a) a total capital and
start-up cost component (annualized over its expected useful life); and (b) a
total operation and maintenance and purchase of services component. The
estimates should take into account costs associated with generating,
maintaining, and disclosing or providing the information. Include
descriptions of methods used to estimate major cost factors including system
and technology acquisition, expected useful life of capital equipment, the
discount rate(s), and the time period over which costs will be incurred.
Capital and start-up costs include, among other items, preparations for
collecting information such as purchasing computers and software;
monitoring, sampling, drilling and testing equipment; and record storage
facilities.

•

If cost estimates are expected to vary widely, agencies should present ranges
of cost burdens and explain the reasons for the variance. The cost of
purchasing or contracting out information collection services should be a

economic or regulatory impact analysis associated with the rulemaking
containing the information collection, as appropriate.

Generally, estimates should not include purchases of equipment or services,
or portions thereof, made: (1) prior to October 1, 1995, (2) to achieve
regulatory compliance with requirements not associated with the information
collection, (3) for reasons other than to provide information or keep records
for the government, or (4) as part of customary and usual business or private
practices.

As noted above in Item 12, no employers are currently producing or using DBCP; therefore, the
Standard imposes no cost burdens on employers.

Provide estimates of annualized cost to the Federal government. Also, provide a
description of the method used to estimate cost, which should include quantification
of hours, operational expenses (such as equipment, overhead, printing, and support
staff), and any other expense that would not have been incurred without this
collection of information. Agencies also may aggregate cost estimates from Items
12, 13, and 14 in a single table.

As noted above in Item 12, no employers are producing DBCP or DBCP-based end-use
products; therefore, the Agency has no annualized costs associated with enforcing the Standard.

Explain the reasons for any program changes or adjustments.

EPA canceled the registration of 1,2-dibromo-3-chloropropane in 1985. According to the TRI (
Toxic Release Inventory ) (2017), a single facility was associated with 1,2-dibromo-3chloropropane in the United States in 2016. This facility is a waste disposal company in Ohio.
(https://www.atsdr.cdc.gov/toxprofiles/tp36-c5.pdf) This information will not affect the 1-hour
place holder for burden purposes because there are less than 10 respondents (industry) that
currently follow the standard.
There are no program changes or adjustments associated with this ICR.

For collections of information whose results will be published, outline plans for
tabulation, and publication. Address any complex analytical techniques that will be
used. Provide the time schedule for the entire project, including beginning and
ending dates of the collection of information, completion of report, publication
dates, and other actions.

OSHA currently collects no information under the DBCP Standard.

If seeking approval to not display the expiration date for OMB approval of the
information collection, explain the reasons that display would be inappropriate.

OSHA lists current valid control numbers in §§1910.8, 1915.8, 1917.4, 1918.4, and 1926.5 and
publishes the expiration date in the Federal Register notice announcing OMB approval of the
Information collection requirement (see 5 CFR 1320.3(f)(3). OSHA believes that this is the most
appropriate and accurate mechanism to inform interested parties of these expiration dates
