emission performance. The analysis shall determine if specific trouble
areas can be identified on the basis of service, operating conditions
or maintenance practices, equipment design, or other process-specific
factors.
(ii) The analysis shall also be used to determine if there are
superior performing pump or pump seal technologies that are applicable
to the service(s), operating conditions, or pump or pump seal designs
associated with poorer than average emission performance. A superior
performing pump or pump seal technology is one with a leak frequency of
less than 10 percent for specific applications in the process unit or
plant site. A candidate superior performing pump or pump seal
technology is one demonstrated or reported in the available literature
or through a group study as having low emission performance and as
being capable of achieving less than 10 percent leaking pumps in the
process unit (or plant site).
(iii) The analysis shall include consideration of the information
specified in paragraphs (d)(5)(iii)(A) through (d)(5)(iii)(C) of this
section.

intracompany program (or through some combination of the two
approaches) and may be for a single process unit, a plant site, a
company, or a group of process units.
(v) The first analysis of the data shall be completed no later than
18 months after the start of the quality improvement program. The first
analysis shall be performed using data collected for a minimum of 6
months. An analysis of the data shall be done each year the process
unit is in the quality improvement program.
(6) Trial evaluation program. A trial evaluation program shall be
conducted at each plant site for which the data analysis does not
identify use of superior performing pump seal technology or pumps that
can be applied to the areas identified as having poorer than average
performance except as provided in paragraph (d)(6)(v) of this section.
The trial program shall be used to evaluate the feasibility of using in
the process unit (or plant site) the pump designs or seal technologies,
and operating and maintenance practices that have been identified by
others as having low emission performance.
(i) The trial evaluation program shall include on-line trials of
pump seal technologies or pump designs and operating and maintenance
practices that have been identified in the available literature or in
analysis by others as having the ability to perform with leak rates
below 10 percent in similar services, as having low probability of
failure, or as having no external actuating mechanism in contact with
the process fluid. If any of the candidate superior performing pump
seal technologies or pumps is not included in the performance trials,
the reasons for rejecting specific technologies from consideration
shall be documented as required in paragraph (e)(3)(ii) of this
section.
(ii) The number of pump seal technologies or pumps in the trial
evaluation program shall be the lesser of 1 percent or two pumps for
programs involving single process units and the lesser of 1 percent or

units. The minimum number of pumps or pump seal technologies in a trial
program shall be one.
(iii) The trial evaluation program shall specify and include
documentation of the information specified in paragraphs (d)(6)(iii)(A)
through (d)(6)(iii)(D) of this section.
(A) The candidate superior performing pump seal designs or
technologies to be evaluated, the stages for evaluating the identified
candidate pump designs or pump seal technologies, including the time
period necessary to test the applicability;
(B) The frequency of monitoring or inspection of the equipment;
(C) The range of operating conditions over which the component will
be evaluated; and
(D) Conclusions regarding the emission performance and the
appropriate operating conditions and services for the trial pump seal
technologies or pumps.
(iv) The performance trials shall initially be conducted at least
for a 6-month period beginning not later than 18 months after the start
of the quality improvement program. No later than 24 months after the
start of the quality improvement program, the owner or operator shall
have identified pump seal technologies or pump designs that combined
with appropriate process, operating, and maintenance practices operate
with low emission performance for specific applications in the process
unit. The owner or operator shall continue to conduct performance
trials as long as no superior performing design or technology has been
identified except as provided in paragraph (d)(6)(vi) of this section.
The initial list of superior emission performance pump designs or pump
seal technologies shall be amended in the future, as appropriate, as
additional information and experience are obtained.
(v) Any plant site with fewer than 400 valves and owned by a
corporation with fewer than 100 employees shall be exempt from trial
evaluations of pump seals or pump designs. Plant sites exempt from the
trial evaluations of pumps shall begin the pump seal or pump
replacement program at the start of the fourth year of the quality
improvement program.
(vi) An owner or operator who has conducted performance trials on
all alternative superior emission performance technologies suitable for
the required applications in the process unit may stop conducting
performance
[[Page 57849]]
trials provided that a superior performing design or technology has
been demonstrated or there are no technically feasible alternative
superior technologies remaining. The owner or operator shall prepare an
engineering evaluation documenting the physical, chemical, or
engineering basis for the judgment that the superior emission
performance technology is technically infeasible or demonstrating that
it would not reduce emissions.
(7) Quality assurance program. Each owner or operator shall prepare
and implement a pump quality assurance program that details purchasing
specifications and maintenance procedures for all pumps and pump seals
in the process unit. The quality assurance program may establish any
number of categories, or classes, of pumps as needed to distinguish
among operating conditions and services associated with poorer than
average emission performance as well as those associated with better
than average emission performance. The quality assurance program shall
be developed considering the findings of the data analysis required
under paragraph (d)(5) of this section, if applicable, the findings of
the trial evaluation required in paragraph (d)(6) of this section, and
the operating conditions in the process unit. The quality assurance
program shall be updated each year as long as the process unit has the
greater of either 10 percent or more leaking pumps or has three leaking
pumps.
(i) The quality assurance program shall meet the requirements
specified in paragraphs (d)(7)(i)(A) through (d)(7)(i)(D) of this
section.
(A) Establish minimum design standards for each category of pumps
or pump seal technology. The design standards shall specify known
critical parameters such as tolerance, manufacturer, materials of
construction, previous usage, or other applicable identified critical
parameters;
(B) Require that all equipment orders specify the design standard
(or minimum tolerances) for the pump or the pump seal;
(C) Provide for an audit procedure for quality control of purchased
equipment to ensure conformance with purchase specifications. The audit
program may be conducted by the owner or operator of the plant site or
process unit or by a designated representative; and
(D) Detail off-line pump maintenance and repair procedures. These
procedures shall include provisions to ensure that rebuilt or
refurbished pumps and pump seals will meet the design specifications
for the pump category and will operate so that emissions are minimized.
(ii) The quality assurance program shall be established no later
than the start of the third year of the quality improvement program for
plant sites with 400 or more valves or 100 or more employees, and no
later than the start of the fourth year of the quality improvement
program for plant sites with less than 400 valves and less than 100
employees.
(8) Pump or pump seal replacement. Beginning at the start of the
third year of the quality improvement program for plant sites with 400
or more valves or 100 or more employees and at the start of the fourth
year of the quality improvement program for plant sites with less than
400 valves and less than 100 employees, the owner or operator shall
replace as described in paragraphs (d)(8)(i) and (d)(8)(ii) of this
section the pumps or pump seals that are not superior emission
performance technology with pumps or pump seals that have been
identified as superior emission performance technology and that comply
with the quality assurance standards for the pump category. Superior
emission performance technology is that category or design of pumps or
pump seals with emission performance that when combined with
appropriate process, operating, and maintenance practices will result
in less than 10 percent leaking pumps for specific applications in the
process unit or plant site. Superior emission performance technology
includes material or design changes to the existing pump, pump seal,
seal support system, installation of multiple mechanical seals or
equivalent, or pump replacement.
(i) Pumps or pump seals shall be replaced at the rate of 20 percent
per year based on the total number of pumps in light liquid service.
The calculated value shall be rounded to the nearest nonzero integer
value. The minimum number of pumps or pump seals shall be one. Pump
replacement shall continue until all pumps subject to the requirements
of Sec. 65.107 are pumps determined to be superior performance
technology.
(ii) The owner or operator may delay replacement of pump seals or
pumps with superior technology until the next planned process unit
shutdown provided the number of pump seals and pumps replaced is
equivalent to the 20 percent or greater annual replacement rate.
(iii) The pumps shall be maintained as specified in the quality
assurance program.
(e) QIP recordkeeping. In addition to the records required by
paragraph (d)(2) of this section, the owner or operator shall maintain

Sec. 65.117 Alternative means of emission limitation: Batch processes.
(a) General requirement. As an alternative to complying with the
requirements of Secs. 65.106 through 65.114 and 65.116, an owner or
operator of a batch process that operates in regulated material service
during the calendar year may comply with one of the standards specified
in paragraphs (b) and (c) of this section, or the owner or operator may
petition for approval of an alternative standard under the provisions
of Sec. 65.102(b). The alternative standards of this section provide
the options of pressure testing or monitoring the equipment for leaks.
The owner or operator may switch among the alternatives provided the
change is documented as specified in paragraph (b)(7) of this section.
(b) Pressure testing of the batch equipment. The following
requirements shall be met if an owner or operator elects to use
pressure testing of batch product-process equipment to demonstrate
compliance with this subpart.
(1) Reconfiguration. Each time equipment is reconfigured for
production of a different product or intermediate, the batch product-
process equipment train shall be pressure-tested for leaks before
regulated material is first fed to the equipment and the equipment is
placed in regulated material service.
(i) When the batch product-process equipment train is reconfigured
to produce a different product, pressure testing is required only for
the new or disturbed equipment.
(ii) Each batch product-process that operates in regulated material
service during a calendar year shall be pressure-tested at least once
during that calendar year.
(iii) Pressure testing is not required for routine seal breaks,
such as changing hoses or filters, that are not part of the
reconfiguration to produce a different product or intermediate.
(2) Testing procedures. The batch product-process equipment shall
be tested either using the procedures specified in paragraph (b)(5) of
this section for pressure vacuum loss or with a liquid using the
procedures specified in paragraph (b)(6) of this section.
(3) Leak detection. (i) For pressure or vacuum tests using a gas, a
leak is detected if the rate of change in pressure is greater than 6.9
kilopascals (1 pound per square inch gauge) in 1 hour or if there is
visible, audible, or olfactory evidence of fluid loss.
(ii) For pressure tests using a liquid, a leak is detected if there
are indications of liquids dripping or if there is other evidence of
fluid loss.
(4) Leak repair. (i) If a leak is detected, it shall be repaired
and the batch product-process equipment shall be retested before
startup of the process.
(ii) If a batch product-process fails the retest or the second of
two consecutive pressure tests, it shall be repaired as soon as
practical but not later than 30 calendar days after the second pressure
test except as specified in paragraph (e) of this section.
(5) Gas pressure test procedure for pressure or vacuum loss. The
procedures specified in paragraphs (b)(5)(i) through (b)(5)(v) of this
section shall be used to pressure test batch product-process equipment
for pressure or vacuum loss to demonstrate compliance with the
requirements of paragraph (b)(3)(i) of this section.
(i) The batch product-process equipment train shall be pressurized
with a gas to a pressure less than the set pressure of any safety
relief devices or valves or to a pressure slightly above the operating
pressure of the equipment, or alternatively the equipment shall be
placed under a vacuum.
(ii) Once the test pressure is obtained, the gas source or vacuum
source shall be shut off.
(iii) The test shall continue for not less than 15 minutes unless
it can be determined in a shorter period of time that the allowable
rate of pressure drop or of pressure rise was exceeded. The pressure in
the batch product-process equipment shall be measured after the gas or
vacuum source is shut off and at the end of the test period. The rate
of change in pressure in the batch product-process equipment shall be
calculated using the following equation:
<greek-D>(P/t)=(|P<INF>f</INF>-P<INF>i</INF>|)/
(t<INF>f</INF>-t<INF>i</INF>) (117-1)
Where:
<greek-D>(P/t)=Change in pressure, pounds per square inch gauge/hr.
P<INF>f</INF>=Final pressure, pounds per square inch gauge.
P<INF>i</INF>=Initial pressure, pounds per square inch gauge.
t<INF>f</INF>-t<INF>i</INF>=Elapsed time, hours.
(iv) The pressure shall be measured using a pressure measurement
device (gauge, manometer, or equivalent) that has a precision of
<INF>#</INF>2.5 millimeters mercury (0.10 inch of mercury) in the range
of test pressure and is capable of measuring pressures up to the relief
set pressure of the pressure relief device. If such a pressure
measurement device is not reasonably available, the owner or operator
shall use a pressure measurement device with a precision of at least
<plus-minus>10 percent of the test pressure of the equipment and shall
extend the duration of the test for the time necessary to detect a
pressure loss or rise that equals a rate of 1 pound per square inch
gauge per hour (7 kilopascals per hour).
(v) An alternative procedure may be used for leak testing the
equipment if the owner or operator demonstrates the alternative
procedure is capable of detecting a pressure loss or rise.
(6) Pressure test procedure using test liquid. The procedures
specified in paragraphs (b)(6)(i) through (b)(g)(iv) of this section
shall be used to pressure test batch product-process equipment using a
liquid to demonstrate compliance with the requirements of paragraph
(b)(3)(ii) of this section.
(i) The batch product-process equipment train or section of the
equipment train shall be filled with the test liquid (for example,
water, alcohol) until normal operating pressure is obtained. Once the
equipment is filled, the liquid source shall be shut off.
(ii) The test shall be conducted for a period of at least 60
minutes unless it can be determined in a shorter period of time that
the test is a failure.
(iii) Each seal in the equipment being tested shall be inspected
for indications of liquid dripping or other indications of fluid loss.
If there are any indications of liquids dripping or of fluid loss, a
leak is detected.
(iv) An alternative procedure may be used for leak testing the
equipment if the owner or operator demonstrates the alternative
procedure is capable of detecting losses of fluid.
(7) Pressure testing recordkeeping. The owner or operator of a
batch product-process who elects to pressure test the batch product-
process equipment train to demonstrate compliance with this subpart
shall maintain records of the information specified in paragraphs
(b)(7)(i) through (b)(7)(v) of this section.
(i) The identification of each product or product code produced
during the calendar year. It is not necessary to identify individual
items of equipment in a batch product-process equipment train.
(ii) Physical tagging of the equipment to identify that it is in
regulated material service and subject to the provisions of this
subpart is not required. Equipment in a batch product-process subject
to the provisions of this subpart may be identified on a plant site
plan, in log entries, or by other appropriate methods.
(iii) The dates of each pressure test required in paragraph (b) of
this section,
[[Page 57851]]
the test pressure, and the pressure drop observed during the test.
(iv) Records of any visible, audible, or olfactory evidence of
fluid loss.
(v) When a batch product-process equipment train does not pass two
consecutive pressure tests, the information specified in paragraphs
(b)(7)(v)(A) through (b)(7)(v)(E) of this section shall be recorded in
a log and kept for 2 years.

process that is subject to the provisions of this subpart is operating.
(iv) The monitoring frequencies specified in paragraph (c)(3)(iii)
of this section are not requirements for monitoring at specific
intervals and can be adjusted to accommodate process operations. An
owner or operator may monitor anytime during the specified monitoring
period (for example, month, quarter, year), provided the monitoring is
conducted at a reasonable interval after completion of the last
monitoring campaign. For example, if the equipment is not operating
during the scheduled monitoring period, the monitoring can be done
during the next period when the process is operating.
(4) If a leak is detected, it shall be repaired as soon as
practical but not later than 15 calendar days after it is detected
except as provided in paragraph (e) of this section.
(d) Added equipment recordkeeping. (1) For batch product-process

(i) When the daily average value of one or more monitored
parameters is outside the permitted range.
(ii) When the period of control or recovery device operation is 4
hours or greater in an operating day and monitoring data are
insufficient to constitute a valid hour of data for at least 75 percent
of the operating hours.
(iii) When the period of control or recovery device operation is
less than 4 hours in an operating day and more than 1 hour during the
period of operation does not constitute a valid hour of data due to
insufficient monitoring data.
(iv) Monitoring data are insufficient to constitute a valid hour of
data as used in paragraphs (d)(1)(ii) and (d)(1)(iii) of this section,
if measured values are unavailable for any of the 15-minute periods
within the hour. For data compression systems approved under
Sec. 65.162(d)(4), monitoring data are insufficient to calculate a
valid hour of data if there are less than four data values recorded
during the hour.
(2) One excused excursion for each control device or recovery
device for each semiannual period is allowed.
(3) The excursions described in paragraphs (d)(3)(i) through
(d)(3)(iii) of this section are not violations, and do not count as
excused excursions.
(i) Excursions which occur during periods of startup, shutdown, and
malfunction, when the source is being operated during such periods in
accordance with its startup, shutdown, and malfunction plan as required
by Sec. 65.6 of subpart A.
(ii) Excursions which occur due to failure to collect a valid hour
of data during periods of startup, shutdown, and malfunction, when the

subpart A.
(iii) Excursions which occur during periods of nonoperation of the
regulated source or portion thereof, resulting in cessation of the
emissions to which monitoring applies.
(4) Nothing in paragraph (d) of this section shall be construed to
allow or excuse a monitoring parameter excursion caused by any activity
that violates other applicable provisions of this part.
(5) Paragraph (d) of this section, except paragraph (d)(3) of this
section, shall apply only to emission points and control devices for
which continuous monitoring is required by this subpart.
(e) Alternative monitoring parameter. An owner or operator may
request approval to monitor control, recovery, halogen scrubber, or
halogen reduction device operating parameters other than those
specified in this subpart by following the procedures specified in
Sec. 65.162(e).
Sec. 65.157 Performance test and flare compliance determination
requirements.
(a) Performance tests and flare compliance determinations. Where
Secs. 65.145 through 65.155 require or the owner or operator elects to
conduct a performance test of a nonflare control device or a halogen
reduction device, or a compliance determination for a flare, the
requirements of paragraphs (b) through (d) of this section apply.
(b) Prior test results and waivers. Initial performance tests and
initial flare compliance determinations are required only as specified
in this subpart.
(1) Unless requested by the Administrator, an owner or operator is
not required to conduct a performance test or flare compliance
determination under this subpart if a prior performance test or
compliance determination was conducted using the same methods specified
in Sec. 65.158 and either no process changes have been made since the
test or the owner or operator can demonstrate that the results of the
performance test, with or without adjustments, reliably demonstrate
compliance despite process changes.
(2) Individual performance tests and flare compliance
determinations may be waived upon written application to the
Administrator per Sec. 65.164(b)(3) if, in the Administrator's
judgment, the source is meeting the relevant standard(s) on a
continuous basis, or the source is being operated under an extension of
compliance under 40 CFR part 63 or a waiver of compliance under 40 CFR
part 61, or the owner or operator has requested an extension of
compliance under 40 CFR part 63 or a waiver of compliance under 40 CFR
part 61, and the Administrator is still considering that request.
(3) Approval of any waiver granted under this section shall not
abrogate the Administrator's authority under the Act or in any way
prohibit the Administrator from later canceling the waiver. The
cancellation will be made only after notification is given to the owner
or operator of the source.
(c) Performance tests and flare compliance determinations schedule.
(1) Unless a waiver of performance testing or flare compliance
determination is obtained under this section or the conditions of
another subpart of this part, the owner or operator shall perform such
tests specified in paragraphs (c)(1)(i) through (c)(1)(vii) of this
section.
(i) Within 180 days after the effective date of a relevant standard
for a new source that has an initial startup date before the effective
date of that standard; or
(ii) Within 180 days after initial startup for a new source that
has an initial startup date after the effective date of a relevant
standard; or
(iii) Within 180 days after the compliance date specified in a
referencing subpart for an existing source or within 180 days after
startup of an existing source if the source begins operation after the
effective date of the relevant 40 CFR part 63 emission standard; or
(iv) Within 180 days after the compliance date for an existing
source subject to an emission standard established pursuant to section
112(f) of the Act; or
(v) Within 180 days after the termination date of the source's
extension of compliance or a waiver of compliance for an existing
source that obtains an extension of compliance under 40 CFR 63.6(i) of
subpart A or a waiver of compliance under 40 CFR 61.11 of subpart A; or
(vi) Within 180 days after the compliance date for a new source,
subject to an emission standard established pursuant to section 112(f)
of the Act, for which construction or reconstruction is commenced after
the proposal date of a relevant standard
[[Page 57865]]
established pursuant to section 112(d) of the Act but before the
proposal date of the relevant standard established pursuant to section
112(f) [see 40 CFR 63.6(b)(4) of subpart A]; or
(vii) When an emission standard promulgated under part 63 is more
stringent than the standard that was proposed [see 40 CFR 63.6(b)(3) of
subpart A], the owner or operator of a new or reconstructed source
subject to that standard for which construction or reconstruction is
commenced between the proposal and promulgation dates of the standard
shall comply with performance testing requirements within 180 days
after the standard's effective date or within 180 days after startup of
the source, whichever is later. If the promulgated standard is more
stringent than the proposed standard, the owner or operator may choose
to demonstrate compliance with either the proposed or the promulgated
standard. If the owner or operator chooses to comply with the proposed
standard initially, the owner or operator shall conduct a second
performance test within 3 years and 180 days after the effective date
of the standard, or after startup of the source, whichever is later, to
demonstrate compliance with the promulgated standard.
(2) The Administrator may require an owner or operator to conduct
performance tests and compliance determinations at the regulated source
at any time when the action is authorized by section 114 of the Act.
(d) Performance testing facilities. If required to do performance
testing, the owner or operator of each new regulated source and, at the
request of the Administrator, the owner or operator of each existing
regulated source, shall provide performance testing facilities as
specified in paragraphs (d)(1) through (d)(5) of this section.
(1) Sampling ports adequate for test methods applicable to such
source. This includes, as applicable, the requirements specified in

safe and adequate testing of a source.
Sec. 65.158 Performance test procedures for control devices.
(a) General procedures. Where Secs. 65.145 through 65.155 require
or the owner or operator elects to conduct a performance test of a
control device or a halogen reduction device, an owner or operator
shall follow the requirements of paragraphs (a)(1) through (a)(3) of
this section, as applicable.
(1) Performance tests shall be conducted at maximum representative
operating conditions for the process unless the Administrator specifies
or approves alternate operating conditions. During the performance
test, an owner or operator may operate the control or halogen reduction
device at maximum or minimum representative operating conditions for
monitored control or halogen reduction device parameters, whichever
results in lower emission reduction. Operations during periods of
startup, shutdown, and malfunction shall not constitute representative
conditions for the purpose of a performance test.
(2) Performance tests shall be conducted and data shall be reduced
in accordance with the test methods and procedures set forth in this
subpart, in each relevant standard, and, if required, in applicable
appendices of 40 CFR parts 51, 60, 61, and 63 unless the Administrator
allows revisions to the test methods as specified in one or more of the
paragraphs (a)(2)(i) through (a)(2)(v) of this section.
(i) The Administrator specifies or approves, in specific cases, the
use of a test method with minor changes in methodology; or
(ii) The Administrator approves the use of an alternative test
method, the results of which the Administrator has determined to be
adequate for indicating whether a specific regulated source is in
compliance. The alternative method or data shall be validated using the
applicable procedures of Method 301 of appendix A of 40 CFR part 63; or
(iii) The Administrator approves shorter sampling times and smaller
sample volumes when necessitated by process variables or other factors;
or
(iv) The Administrator waives the requirement for the performance
test as provided in Sec. 65.157(b)(2) because the owner or operator of
a regulated source has demonstrated by other means to the
Administrator's satisfaction that the regulated source is in compliance
with the relevant standard; or
(v) The Administrator approves the use of an equivalent method.
(3) Each performance test shall consist of three separate runs
using the applicable test method. Except as provided in paragraphs
(a)(3)(i) and (a)(3)(ii) of this section, each run shall be conducted
for at least 1 hour and under the conditions specified in this section.
For the purpose of determining compliance with an applicable standard,
the arithmetic mean of results of the three runs shall apply. In the
event that a sample is accidentally lost or conditions occur in which
one of the three runs must be discontinued because of forced shutdown,
failure of an irreplaceable portion of the sample train, extreme
meteorological conditions, or other circumstances beyond the owner or
operator's control, compliance may, upon the Administrator's approval,
be determined using the arithmetic mean of the results of the two other
runs.
(i) For control devices that are used to control emissions from
transfer racks (except low-throughput transfer racks), and that are
capable of continuous vapor processing but do not handle continuous
emissions or emissions from transfer racks that load simultaneously
from multiple loading arms each run shall represent at least one
complete tank truck or tank car loading period during which regulated
materials are loaded, and samples shall be collected using integrated
sampling or grab samples taken at least four times per hour at
approximately equal intervals of time, such as 15-minute intervals.
(ii) For intermittent vapor processing systems used for controlling
transfer rack emissions (except low-throughput transfer racks) that do
not handle continuous emissions or multiple loading arms of a transfer
rack that load simultaneously, each run shall represent at least one
complete control device cycle, and samples shall be collected using
integrated sampling or grab samples taken at least four times per hour
at approximately equal intervals of time, such as 15-minute intervals.
(b) Test methods. Where Secs. 65.145 through 65.155 require or the
owner or operator elects to conduct a performance test of a control
device or a halogen reduction device, an owner or operator shall
conduct that performance test using the procedures in paragraphs (b)(1)
through (b)(4) of this section, as applicable. The regulated material
concentration and percent reduction may be measured as either total
regulated material or as TOC minus methane and ethane according to the
procedures specified.

total regulated material or TOC (minus methane and ethane) limit, the
owner or operator shall use Method 18 of 40 CFR part 60, appendix A, to
measure either TOC minus methane and ethane or total regulated
material, as applicable. Alternatively, any other method or data that
have been validated according to the applicable procedures in Method
301 of appendix A of 40 CFR part 63, may be used. Method 25A may be
used for transfer racks as detailed in paragraph (b)(3)(iv) of this

shall be between 1.5 and 2.5 times the concentration being measured.
(C) Use of Method 25A of 40 CFR part 60, appendix A, is acceptable
if the response from the high-level calibration gas is at least 20
times the standard deviation of the response from the zero calibration

Sec. 65.161 Continuous records and monitoring system data handling.
(a) Required records. Where this subpart requires a monitoring
device capable of providing a continuous record, the owner or operator
shall maintain the record specified in paragraph (a)(1), (a)(2),
(a)(3), or (a)(4) of this section, as applicable. The provisions of
this section apply to owners and operators of storage vessels and low-
throughput transfer racks only if specified by the applicable
monitoring plan established under Sec. 65.165(c)(1) and (c)(2).
(1) A record of values measured at least once every 15 minutes or
each measured value for systems that measure more frequently than once
every 15 minutes; or
(2) A record of block average values for 15-minute or shorter
periods calculated from all measured data values during each period or
from at least one measured data value per minute if measured more
frequently than once per minute; or
(3) A record of block hourly average values calculated from each
15-minute block average period or from at least one measured value per
minute if measured more frequently than once per minute, and a record
of the most recent 3 valid hours of continuous (15-minute or shorter)
records meeting the requirements of paragraph (a)(1) or (a)(2) of this
section.
(4) A record as required by an alternative approved under
Sec. 65.162(d).
(b) Excluded data. Monitoring data recorded during periods
identified in paragraphs (b)(1) through (b)(3) of this section shall
not be included in any average computed to determine compliance under
this subpart.
(1) Monitoring system breakdowns, repairs, preventive maintenance,

(2) Periods of non-operation of the process unit (or portion
thereof), resulting in cessation of the emissions to which the
monitoring applies; and
(3) Startups, shutdowns, and malfunctions.
(c) Additional records. In addition to the records specified in
paragraph (a) of this section, owners or operators shall also keep
records as specified in paragraphs (c)(1) and (c)(2) of this section
unless an alternative monitoring or recordkeeping system has been
requested and approved under Sec. 65.162(d).
(1) Except as specified in paragraph (c)(2) of this section, daily
average values of each continuously monitored parameter shall be
calculated from data meeting the specifications of paragraph (b) of
this section for each operating day and retained for 5 years. The data
shall be reported in the periodic report as specified in
Sec. 65.166(f), if applicable.
(i) The daily average shall be calculated as the average of all
values for a monitored parameter recorded during the operating day. The
average shall cover a 24-hour period if operation is continuous, or the
number of hours of operation per operating day if operation is not
continuous (for example, for transfer racks, the average shall cover
periods of loading). If values are measured more frequently than once
per minute, a single value for each minute may be used to calculate the
daily average instead of all measured values.
(ii) The operating day shall be the period defined in the operating
permit or the Initial Compliance Status Report. It may be from midnight
to midnight or another daily period.
(2) If all recorded values for a monitored parameter during an
operating day are within the range established in the Initial
Compliance Status Report or in the operating permit, the owner or
operator may record that
[[Page 57870]]
all values were within the range and retain this record for 5 years
rather than calculating and recording a daily average for that
operating day.
(d) Valid data. Unless determined to be excluded data according to
paragraph (b) of this section, the data collected pursuant to
paragraphs (a) through (c) of this section shall be considered valid.
(e) Alternative recordkeeping. For any parameter with respect to
any item of equipment, the owner or operator may implement the
recordkeeping requirements in paragraph (e)(1) or (e)(2) of this
section as alternatives to the continuous parameter monitoring and
recordkeeping provisions listed in paragraphs (a) through (c) of this
section. The owner or operator shall retain each record required by
paragraph (e)(1) or (e)(2) of this section as provided in Sec. 65.4 of
subpart A of this part.
(1) The owner or operator may retain only the daily average value
and is not required to retain more frequently monitored operating
parameter values for a monitored parameter with respect to an item of
equipment if the requirements of paragraphs (e)(1)(i) through
(e)(1)(vi) of this section are met. The owner or operator shall notify
the Administrator of implementation of paragraph (e)(1) of this section
in the Initial Compliance Status Report as required in Sec. 65.165(e)
or, if the Initial Compliance Status Report has already been submitted,
in the periodic report as required in Sec. 65.166(f)(4) immediately
preceding implementation of the requirements of paragraph (e)(1) of
this section.
(i) The monitoring system shall be capable of detecting unrealistic
or impossible data during periods of operation other than startups,
shutdowns, or malfunctions (for example, a temperature reading of -200
deg.C on a boiler) and will alert the operator by alarm or other means.
The owner or operator shall record the occurrence. All instances of the
alarm or other alert in an operating day constitute a single
occurrence.
(ii) The monitoring system shall generate a running average of the
monitoring values, updated at least hourly throughout each operating
day, that have been obtained during that operating day, and the
capability to observe this average is readily available to the
Administrator on-site during the operating day. The owner or operator
shall record the occurrence of any period meeting the criteria in
paragraphs (e)(1)(ii)(A) through (e)(1)(ii)(C) of this section. All
instances in an operating day constitute a single occurrence.
(A) The running average is above the maximum or below the minimum
established limits; and
(B) The running average is based on at least six 1-hour average
values; and
(C) The running average reflects a period of operation other than a
startup, shutdown, or malfunction.
(iii) The monitoring system shall be capable of detecting
unchanging data during periods of operation other than startups,
shutdowns, or malfunctions except in circumstances where the presence
of unchanging data is the expected operating condition based on past
experience (for example, pH in some scrubbers), and will alert the
operator by alarm or other means. The owner or operator shall record
the occurrence. All instances of the alarm or other alert in an
operating day constitute a single occurrence.
(iv) The monitoring system shall alert the owner or operator by an
alarm if the running average parameter value calculated under paragraph
(e)(1)(ii) of this section reaches a set point that is appropriately
related to the established limit for the parameter that is being
monitored.
(v) The owner or operator shall verify the proper functioning of
the monitoring system, including its ability to comply with the
requirements of paragraph (e)(1) of this section, at the times
specified in paragraphs (e)(1)(v)(A) through (e)(1)(v)(C) of this
section. The owner or operator shall document that the required
verifications occurred.
(A) Upon initial installation.
(B) Annually after initial installation.
(C) After any change to the programming or equipment constituting
the monitoring system, that might reasonably be expected to alter the
monitoring system's ability to comply with the requirements of this
section.
(vi) The owner or operator shall retain the records identified in
paragraphs (e)(1)(vi)(A) through (e)(1)(vi)(C) of this section.

which the owner or operator has elected to comply with the requirements
of Sec. 65.162(e).
(B) A description of the applicable monitoring system(s) and of how
compliance will be achieved with each requirement of paragraph
(e)(1)(i) through (e)(1)(v) of this section. The description shall
identify the location and format (for example, on-line storage; log
entries) for each required record. If the description changes, the
owner or operator shall retain both the current and the most recent
outdated description. Owners and operators shall retain the current
description of the monitoring system as long as the description is
current, but not less than 5 years from the date of its creation. The
current description shall be retained on-site at all times or be
accessible from a central location by computer or other means that
provide access within 2 hours after a request. The owner or operator
shall retain the most recent outdated description at least until 5
years from the date of its creation. The outdated description shall be
retained on-site (or accessible from a central location by computer
that provides access within 2 hours after a request) at least 6 months
after being outdated. Thereafter, the outdated description may be
stored off-site.
(C) A description and the date of any change to the monitoring
system that would reasonably be expected to affect its ability to
comply with the requirements of paragraph (e)(1) of this section.
(2) If an owner or operator has elected to implement the
requirements of paragraph (e)(1) of this section and a period of 6
consecutive months has passed without an excursion as defined in
paragraph (e)(2)(iv) of this section, the owner or operator is no
longer required to record the daily average value for that parameter
for that unit of equipment for any operating day when the daily average
value is less than the maximum or greater than the minimum established
limit. With approval by the Administrator, monitoring data generated
prior to the compliance date of this subpart shall be credited toward
the period of 6 consecutive months if the parameter limit and the
monitoring were required and/or approved by the Administrator.
(i) If the owner or operator elects not to retain the daily average
values, the owner or operator shall notify the Administrator in the
next periodic report. The notification shall identify the parameter and
unit of equipment.
(ii) If there is an excursion as defined in paragraph (e)(2)(iv) of
this section on any operating day after the owner or operator has
ceased recording daily averages as provided in paragraph (e)(2) of this
section, the owner or operator shall immediately resume retaining the
daily average value for each day and shall notify the Administrator in
the next periodic report. The owner or operator shall continue to
retain each daily average value until another period of 6 consecutive
months has passed without an excursion.
(iii) The owner or operator shall retain the records specified in
paragraphs (e)(1)(i) through (e)(1)(vi) of this section for the
duration specified in Sec. 65.4 of subpart A of this part. For any
calendar
[[Page 57871]]
week, if compliance with paragraphs (e)(1)(i) through (e)(1)(iv) of
this section does not result in retention of a record of at least one
occurrence or measured parameter value, the owner or operator shall
record and retain at least one parameter value during a period of
operation other than a startup, shutdown, or malfunction.
(iv) For purposes of paragraph (e) of this section, an excursion
means that the daily average value of monitoring data for a parameter
is greater than the maximum or less than the minimum established value
except as provided in paragraphs (e)(2)(iv)(A) and (e)(2)(iv)(B) of
this section.
(A) The daily average value during any startup, shutdown, or
malfunction shall not be considered an excursion for purposes of
paragraph (e) if the owner or operator follows the applicable
provisions of the startup, shutdown, and malfunction plan required by
Sec. 65.6 of subpart A of this part.
(B) An excused excursion as described in Sec. 65.156(d) shall not
be considered an excursion for purposes of paragraph (e) of this
section.
