SUPPORTING STATEMENT
Safety Defects; Examination, Correction and Records, 30 C.F.R. §§ 56/57.14100,
56/57.13015, 56/57.13030, and 56/57.18002 (pertains to metal and nonmetal surface and
underground mines)

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.

Section 103(h) of the Federal Mine Safety and Health Act of 1977 (Mine Act), 30 U.S.C. §
813, authorizes MSHA to collect information necessary to carry out its duty in protecting
the safety and health of miners.
Title 30 C.F.R. §§ 56.13015 and 57.13015 require compressed-air receivers and other
unfired pressure vessels be inspected by inspectors holding a valid National Board
Commission and in accordance with the applicable chapters of the National Board
Inspection Code, a Manual for Boiler and Pressure Vessels Inspectors, 1979. Safety
defects found on compressed-air receivers and other unfired pressure vessels have
caused injuries and fatalities in the mining industry.
Records of inspections shall be kept in accordance with the requirements of the National
Board Inspection Code and the records shall be made available to the Secretary or
his/her authorized representative.
Title 30 C.F.R. §§ 56.13030 and 57.13030 require that fired pressure vessels (boilers) be
equipped with water level gauges, pressure gauges, automatic pressure-relief valves,
blowdown piping and other safety devices approved by the American Society of
Mechanical Engineers (ASME) to protect against hazards from overpressure, flameouts,
fuel interruptions and low water level.
These sections also require that records of inspection and repairs be retained by the mine
operator in accordance with the requirements of the ASME Boiler and Pressure Vessel
Code and the National Board Inspection Code (progressive records - no limit on
retention time) and shall be made available to the Secretary or his authorized
representative.
Title 30 C.F.R. §§ 56.14100 and 57.14100 require operators to inspect equipment,
machinery, and tools that are to be used during a shift for safety defects before the
equipment is placed in operation. Defects affecting safety are required to be corrected in
a timely manner. In instances where the defect makes continued operation of the
equipment hazardous to persons, the standards require removal from service, tagging to

identify that it is out of use, and repair before use is resumed.
Safety defects on self-propelled equipment account for many injuries and fatalities in the
mining industry. Inspection of this equipment prior to use is required to ensure safe
operation. The equipment operator is required to make a visual and operational check of
the various primary operating systems that affect safety, such as brakes, lights, tires,
steering, and related items. Any defects found are required to be either corrected
immediately, or reported to and recorded by the mine operator prior to the timely
correction.
A record is not required if unsafe conditions are not present upon examination prior to
use if the defect is corrected immediately. The precise format in which the record is kept
is left to the discretion of the mine operator.
Reports of uncorrected defects are required to be recorded by the mine operator and
kept at the mine office from the date the defects are recorded, until the defects are
corrected.
Title 30 C.F.R. §§ 56.18002 and 57.18002 require that a competent person designated by
the operator examine each working place at least once each shift for conditions which
may adversely affect safety or health. A record of such examinations shall be kept by the
operator for a period of one year and shall be made available for review by the Secretary
or his/her authorized representative.
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.

The records are used by industry management and maintenance personnel to ensure
that defects are not overlooked, that repairs are made, and to monitor when and how
often maintenance is performed on certain equipment, machinery, and tools.
Additionally, the inspection records denote any hazards that were discovered and how
the hazards or unsafe conditions were abated. Federal mine inspectors use the records
to ensure that unsafe conditions are identified and corrected.
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.

No improved information technology has been identified that would reduce the burden;
however, in order to comply with the Government Paperwork Elimination Act, mine
operators may retain the records in whatever method they choose, which may include
utilizing computer technology.

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 2 above.

There are no similar records that could be used or modified for use in lieu of the
required records. The Agency requires a record to be kept to comply with requirements
of 30 C.F.R. §§ 56.14100 and 57.14100 only when conditions or situations need close
monitoring, maintenance, or repair to safeguard miners using the equipment. Title 30
C.F.R. §§ 56.13015, 57.13015, 56.13030, 57.13030, 56.18002 and 57.18002 require that
records be kept of inspections. Such records are used to ensure that a regular inspection
schedule is maintained and/or that any unsafe conditions are discovered and corrected.
5. If the collection of information impacts small businesses or other small entities (Item 5 of OMB Form 83I), describe any methods used to minimize burden.

This information does not have a significant impact on small businesses or other small
entities. However, MSHA has made available on our web-site various sources of
information, such as “Technical Assistance,” “Best Practices,” and an “Accident
Prevention” site which may aid such small businesses and other small entities in
complying with and reducing the burden associated with these standards.
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.

Further reductions of these requirements could allow unsafe equipment to remain in
operation; thereby, jeopardizing the safety of miners. Section 101(a)(9) of the Mine Act
prohibits any regulatory action which would reduce the protection given miners by an
existing standard.
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-inaid, 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 unnecessarily impedes sharing of data with other agencies for compatible confidential use; or

July 2007
3

1219-0089
· 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.

This collection of information is consistent with the guidelines in 5 C.F.R. § 1320.5.
8. If applicable, provide a copy and identify the data 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 circumstances should be explained.

MSHA published a 60-day preclearance Federal Register notice on May 9, 2007 (Volume
72, Number 89, Pages 26427-26428), soliciting public comments regarding the extension
of this information collection. No comments were received.
9. Explain any decision to provide any payment or gift to respondents, other than remuneration of
contractors or grantees.

MSHA does not provide payments or gifts to respondents.
10. Describe any assurance of confidentiality provided to respondents and the basis for the assurance in
statute, regulation, or agency policy.

There is no assurance of confidentiality provided to respondents. Records are
maintained by the operator.
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 from whom the information is requested, and any
steps to be taken to obtain their consent.

There are no questions of a sensitive nature.

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 and aggregate the hour burdens in Item 13 of OMB Form 83-I.

·

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.

Burden cost figures used in this section are based on salaries reported by MSHA - 2005
Survey Results. The salary of a mine supervisor is $47.10 per hour; a MNM miner $22.55
per hour; and clerical staff $22.17per hour.
30 C.F.R. §§ 56.13015 and 57.13015
Approximately 12,557mines are subject to the standards. The standards require that
compressed-air receivers and other unfired pressure vessels be inspected by inspectors
holding a valid National Board Commission and in accordance with the applicable
chapters of the National Board Inspection Code, a manual for Boiler and Pressure
Vessels Inspectors, 1979. There are approximately 3,389 compressed-air receivers and
other unfired pressure vessels that must be inspected annually. MSHA estimates that the
time required for recording would be approximately 10 minutes (.166 hour) per vessel.
3,389 vessels x 1 exam/vessel x .166 hour = 563 hours

Approximately 12,557mines are subject to the standards. The standards require that
records of inspection and repairs be retained by the mine operator in accordance with
the requirements of the ASME Boiler and Pressure Vessel Code and the National Board
Inspection Code. There are approximately 504 fired pressure vessels (boilers) that must
be inspected annually. MSHA estimates that the time required for recording would be
approximately 10 minutes (.166 hour).

For the purpose of this analysis, approximately 12,557 metal and nonmetal mines are
subject to these standards. These standards require that an inspection be made for every
shift for equipment that is to be used. Further, a record is required to be made of any
defects affecting safety that are not corrected. A small mine is defined by MSHA as a
mine or mill employing fewer than 20 miners and a large mine is defined as a mine or
mill employing 20 miners or more. Small mining operations usually have only a few
pieces of equipment; larger mines may have 100 or more pieces of equipment.
MSHA estimates that 2,521,568 work shifts occur each year at all mines covered by these
standards. Small mines, as defined above, comprise 88% of Metal and Nonmetal mines;
large mines comprise 12% of Metal and Nonmetal mines. Small mines are estimated to
conduct two inspections every shift. Large mines are estimated to conduct fifteen
inspections each shift. MSHA estimates that it will take an average of 5 minutes (.08
hour) to record the required information.
Small Mine Burden and Cost:
2,521,568 work shifts/year X .88 = 2,218,979 shifts/year
2,218,979 shifts/year x 2 inspections/shift = 4,437,960 inspections/year
4,437,960 inspection/year x .08 hour = 355,037 hours/year
355,037 hours/year x $22.55/hour wage = $8,006,084

30 C.F.R. §§ 56.18002 and 57.18002
For the purpose of this analysis there are approximately 12,557 mines that are subject to
these standards. These standards require that a competent person designated by the
mine operator examine each working place at least once each shift for conditions which
may adversely affect safety or health. A record that such examinations were conducted
shall be kept by the operator for a period of one year and shall be made available for
review by the Secretary or his/her authorized representative.
Of the 12,557 mines subject to these standards, 6,687 mines have been designated as
intermittent mines. To determine the number of work place examinations occurring at
intermittent mines, the average number of hours reported was divided by the average
number of employees providing the average number of hours per employee per year.
The resultant figure was divided by eight hours, resulting in the estimated number of
eight hour work shifts per year. The average number of shifts was multiplied by the
number of intermittent mines to obtain 719,187, the total number of workplace
examinations for intermittent mines per year.
To determine the number of work place examinations occurring at other Metal and
Nonmetal mines, the number of shifts for each day was calculated. The number of shifts
each day was multiplied by the calculated number of workdays per year for a total of
1,802,381, the number of work place examinations conducted at all mines except
intermittent mines.
The numbers of work place examinations for intermittent and all other mines were
added to provide the total number of workplace examinations conducted in Metal and
Nonmetal mines for the year. MSHA estimates that the time required for the
recordkeeping activities would be approximately 12 minutes (.20 hour) per mine.

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 part of this cost burden estimate. In developing cost burden
estimates, agencies may consult with a sample of respondents (fewer than 10), utilize the 60-day
pre-OMB submission public comment process and use existing 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.

There are no additional costs.
14. 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.

Records are examined by Federal mine inspectors in the course of routine mine
inspections. Therefore, these requirements do not result in additional cost to the Federal
government.
15.

Explain the reasons for any program changes or adjustments reporting in Items 13 or 14 of the OMB
Form 83-I.

The increase in respondents (from 12,163 to 12,557), responses (from 11,442,570 to
11,502,241), and hour burden (from 1,208,407 to 1,223,104) reflects the increase in the
number of mines. Burden cost remains unchanged at $0.
16. 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.

MSHA does not intend to publish the results of this information collection.
17. If seeking approval to not display the expiration date for OMB approval of the information collection,
explain the reasons that display would be inappropriate.

There are no forms associated with this information collection; therefore, MSHA is not
seeking approval to not display the expiration date for OMB approval of this
information collection.

B.

Collection of Information Employment Statistical Methods

The agency should be prepared to justify its decision not to use statistical methods in any case where such
methods might reduce burden or improve accuracy of results. When Item 17 on the Form OMB 83-I is
checked "Yes", the following documentation should be included in the Supporting Statement to the extent
that it applies to the methods proposed:
1. Describe (including a numerical estimate) the potential respondent universe and any sampling or other
respondent selection methods to be used. Data on the number of entities (e.g., establishments, State and

July 2007
9

1219-0089
local government units, households, or persons) in the universe covered by the collection and in the
corresponding sample are to be provided in tabular form for the universe as a whole and for each of the
strata in the proposed sample. Indicate expected response rates for the collection as a whole. If the
collection had been conducted previously, include the actual response rate achieved during the last
collection.
2.

Describe the procedures for the collection of information including:
·
Statistical methodology for stratification and sample selection,
·
Estimation procedure,
Degree of accuracy needed for the purpose described in the justification,
·
·
Unusual problems requiring specialized sampling procedures, and
·
Any use of periodic (less frequently than annual) data collection cycles to reduce burden.3.
Describe methods to maximize response rates and to deal with issues of non-response. The
accuracy and reliability of information collected must be shown to be adequate for intended
uses. For collections based on sampling, a special justification must be provided
for any collection that will not yield "reliable" data that can be generalized to the universe
studied.

4. Describe any tests of procedures or methods to be undertaken. Testing is encouraged as an effective
means of refining collections of information to minimize burden and improve utility. Tests must be
approved if they call for answers to identical questions from 10 or more respondents. A proposed test or set
of tests may be submitted for approval separately or in combination with the main collection of information.
5. Provide the name and telephone number of individuals consulted on statistical aspects of the design and
the name of the agency unit, contractor(s), grantee(s), or other person(s) who will actually collect and/or
analyze the information for the agency.

As statistical analysis is not required by the regulation, questions 1 through 5 do not
apply.
