         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 63--NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR SOURCE CATEGORIES--Table of Contents
 
 Subpart GGG--National Emission Standards for Pharmaceuticals Production
 
Sec. 63.1255  Standards: Equipment leaks.

    (a) General Equipment Leak Requirements. (1) The provisions of this 
section apply to pumps, compressors, agitators, pressure relief devices, 
sampling connection systems, open-ended valves or lines, valves, 
connectors, instrumentation systems, control devices, and closed-vent 
systems required by this section that are intended to operate in organic 
hazardous air pollutant service 300 hours or more during the calendar 
year within a source subject to the provisions of this subpart.
    (2) Consistency with other regulations. After the compliance date 
for a process, equipment subject to both this section and either of the 
following will be required to comply only with the provisions of this 
subpart:
    (i) 40 CFR part 60.
    (ii) 40 CFR part 61.
    (3) [Reserved]
    (4) The provisions in Sec. 63.1(a)(3) of subpart A of this part do not 
alter the provisions in paragraph (a)(2) of this section.
    (5) Lines and equipment not containing process fluids are not 
subject to the provisions of this section. Utilities, and other 
nonprocess lines, such as heating and cooling systems which do not 
combine their materials with those in the processes they serve, are not 
considered to be part of a process.

[[Page 92]]

    (6) The provisions of this section do not apply to bench-scale 
processes, regardless of whether the processes are located at the same 
plant site as a process subject to the provisions of this subpart.
    (7) Equipment to which this section applies shall be identified such 
that it can be distinguished readily from equipment that is not subject 
to this section. Identification of the equipment does not require 
physical tagging of the equipment. For example, the equipment may be 
identified on a plant site plan, in log entries, or by designation of 
process boundaries by some form of weatherproof identification. If 
changes are made to the affected source subject to the leak detection 
requirements, equipment identification for each type of component shall 
be updated, if needed, within 90 calendar days or by the next Periodic 
Report following the end of the monitoring period for that component, 
whichever is later.
    (8) Equipment that is in vacuum service is excluded from the 
requirements of this section.
    (9) Equipment that is in organic HAP service, but is in such service 
less than 300 hours per calendar year, is excluded from the requirements 
of this section if it is identified as required in paragraph (g)(9) of 
this section.
    (10) When each leak is detected by visual, audible, or olfactory 
means, or by monitoring as described in Sec. 63.180(b) or (c), the 
following requirements apply:
    (i) A weatherproof and readily visible identification, marked with 
the equipment identification number, shall be attached to the leaking 
equipment.
    (ii) The identification on a valve in light liquid or gas/vapor 
service may be removed after it has been monitored as specified in 
paragraph (e)(7)(iii) of this section, and no leak has been detected 
during the follow-up monitoring.
    (iii) The identification on equipment, except on a valve in light 
liquid or gas/vapor service, may be removed after it has been repaired.
    (11) Except as provided in paragraph (a)(11)(i) of this section, all 
terms in this subpart that define a period of time for completion of 
required tasks (e.g., weekly, monthly, quarterly, annual) refer to the 
standard calendar periods unless specified otherwise in the section or 
paragraph that imposes the requirement.
    (i) If the initial compliance date does not coincide with the 
beginning of the standard calendar period, an owner or operator may 
elect to utilize a period beginning on the compliance date, or may elect 
to comply in accordance with the provisions of paragraph (a)(11)(ii) or 
(iii) of this section.
    (ii) Time periods specified in this subpart for completion of 
required tasks may be changed by mutual agreement between the owner or 
operator and the Administrator, as specified in subpart A of this part. 
For each time period that is changed by agreement, the revised period 
shall remain in effect until it is changed. A new request is not 
necessary for each recurring period.
    (iii) Except as provided in paragraph (a)(11)(i) or (ii) of this 
section, where the period specified for compliance is a standard 
calendar period, if the initial compliance date does not coincide with 
the beginning of the calendar period, compliance shall be required 
according to the schedule specified in paragraph (a)(11)(iii)(A) or (B) 
of this section, as appropriate.
    (A) Compliance shall be required before the end of the standard 
calendar period within which the initial compliance date occurs if there 
remain at least 3 days for tasks that must be performed weekly, at least 
2 weeks for tasks that must be performed monthly, at least 1 month for 
tasks that must be performed each quarter, or at least 3 months for 
tasks that must be performed annually; or
    (B) In all other cases, compliance shall be required before the end 
of the first full standard calendar period after the period within which 
the initial compliance date occurs.
    (iv) In all instances where a provision of this subpart requires 
completion of a task during each of multiple successive periods, an 
owner or operator may perform the required task at any time during each 
period, provided the task is conducted at a reasonable interval after 
completion of the task during the previous period.

[[Page 93]]

    (12) In all cases where the provisions of this subpart require an 
owner or operator to repair leaks by a specified time after the leak is 
detected, it is a violation of this section to fail to take action to 
repair the leaks within the specified time. If action is taken to repair 
the leaks within the specified time, failure of that action to 
successfully repair the leak is not a violation of this section. 
However, if the repairs are unsuccessful, a leak is detected and the 
owner or operator shall take further action as required by applicable 
provisions of this section.
    (b) References. (1) The owner or operator of a source subject to 
this section shall comply with the provisions of subpart H of this part, 
as specified in paragraphs (b)(2) through (4) of this section. The term 
``process unit'' as used in subpart H of this part shall be considered 
to be defined the same as ``group of processes'' for sources subject to 
this subpart GGG. The term ``fuel gas system,'' as used in subpart H of 
this part, shall not apply for the purposes of this subpart GGG.

63.174, 63.178, and 63.180, except as specified in paragraphs (b)(4)(i) 
through (vi) of this section.
    (i) Section 63.171 shall apply, except Sec. 63.171(a) shall not apply. 
Instead, delay of repair of equipment for which leaks have been detected 
is allowed if one of the conditions in paragraphs (b)(4)(i)(A) through 
(B) exists:
    (A) The repair is technically infeasible without a process shutdown. 
Repair of this equipment shall occur by the end of the next scheduled 
process shutdown.
    (B) The owner or operator determines that repair personnel would be 
exposed to an immediate danger if attempting to repair without a process 
shutdown. Repair of this equipment shall occur by the end of the next 
scheduled process shutdown.
    (ii) Section 63.172 shall apply for closed-vent systems used to 
comply with this section, and for control devices used to comply with 
this section only, except:
    (A) Section 63.172(k) and (l) shall not apply. The owner or operator 
shall instead comply with paragraph (f) of this section.

[[Page 94]]

    (B) Owners or operators may, instead of complying with the 
provisions of Sec. 63.172(f), design a closed-vent system to operate at a 
pressure below atmospheric pressure. The system shall be equipped with 
at least one pressure gage or other pressure measurement device that can 
be read from a readily accessible location to verify that negative 
pressure is being maintained in the closed-vent system when the 
associated control device is operating.
    (C) The requirements apply at all times, except as specified in Sec. 
63.1250(g). The owner or operator may not comply with the planned 
routine maintenance provisions in Sec. 63.1252(h).
    (iii) Section 63.174 shall apply except:
    (A) Section 63.174(f), (g), and (h) shall not apply. Instead of Sec. 
63.174(f), (g), and (h), the owner or operator shall comply with 
paragraph (f) of this section. Section 63.174(b)(3) shall not apply. 
Instead of Sec. 63.174(b)(3), the owner or operator shall comply with 
paragraphs (b)(4)(iii)(B) through (F) of this section.
    (B) If the percent leaking connectors in a group of processes was 
greater than or equal to 0.5 percent during the initial monitoring 
period, monitoring shall be performed once per year until the percent 
leaking connectors is less than 0.5 percent.
    (C) If the percent leaking connectors in the group of processes was 
less than 0.5 percent, but equal to or greater than 0.25 percent, during 
the initial or last required monitoring period, the owner or operator 
may elect to monitor once every 4 years. An owner or operator may comply 
with the requirements of this paragraph by monitoring at least 40 
percent of the connectors in the first 2 years and the remainder of the 
connectors within the next 2 years. The percent leaking connectors will 
be calculated for the total of all required monitoring performed during 
the 4-year period.
    (D) Except as provided in paragraph (b)(4)(iii)(B) of this section, 
if leaking connectors comprise at least 0.5 percent but less than 1.0 
percent of the connectors during the last monitoring period, the owner 
or operator shall monitor at least once every 2 years for the next 
monitoring period. At the end of that 2-year monitoring period, if the 
percent leaking connectors is greater than or equal to 0.5 percent, the 
owner or operator shall monitor once per year until the percent leaking 
connectors is less than 0.5 percent. If, at the end of a monitoring 
period, the percent leaking connectors is less than 0.5 percent, the 
owner or operator shall monitor in accordance with paragraph 
(b)(4)(iii)(C) or (F) of this section, as appropriate.
    (E) If an owner or operator determines that 1 percent or greater of 
the connectors in a group of processes are leaking, the owner or 
operator shall monitor the connectors once per year. The owner or 
operator may elect to use the provisions of paragraph (b)(4)(iii)(C), 
(D), or (F) of this section, as appropriate, after a monitoring period 
in which less than 1 percent of the connectors are determined to be 
leaking.
    (F) The owner or operator may elect to perform monitoring once every 
8 years if the percent leaking connectors in the group of processes was 
less than 0.25 percent during the initial or last required monitoring 
period. An owner or operator shall monitor at least 50 percent of the 
connectors in the first 4 years and the remainder of the connectors 
within the next 4 years. If the percent leaking connectors in the first 
4 years is equal to or greater than 0.35 percent, the monitoring program 
shall revert at that time to the appropriate monitoring frequency 
specified in paragraph (b)(4)(iii)(C), (D), or (E) of this section.
    (iv) Section 63.178 shall apply except:
    (A) Section 63.178(b), requirements for pressure testing, may be 
applied to all processes (not just batch processes) and to supply lines 
between storage and processing areas.
    (B) For pumps, the phrase ``at the frequencies specified in Table 1 
of this subpart'' in Sec. 63.178(c)(3)(iii) shall mean ``quarterly'' for 
the purposes of this subpart.
    (v) Section 63.180 shall apply except Sec. 63.180(b)(4)(ii)(A) through 
(C) shall not apply. Instead, calibration gases shall be a mixture of 
methane and air at a concentration of approximately, but less than, 
10,000 parts per million methane for agitators; 2,000 parts per million 
for pumps; and 500 parts per million for all other equipment, except as 
provided in Sec. 63.180(b)(4)(iii).

[[Page 95]]

    (vi) When Secs. 63.171, 63.172, 63.174, 63.178, and 63.180 reference 
other sections in subpart H of this part, the references shall mean 
those sections specified in paragraphs (b)(2) and (b)(4)(i) through (v) 
of this section, as applicable.
    (c) Standards for Pumps in Light Liquid Service and Agitators in 
Gas/Vapor Service and in Light Liquid Service. (1) The provisions of 
this section apply to each pump that is in light organic HAP liquid 
service, and to each agitator in organic HAP gas/vapor service or in 
light organic HAP liquid service.
    (2)(i) Monitoring. Each pump and agitator subject to this section 
shall be monitored quarterly to detect leaks by the method specified in 
Sec. 63.180(b) except as provided in Secs. 63.177, 63.178, paragraph (f) of 
this section, and paragraphs (c)(5) through (9) of this section.
    (ii) Leak definition. The instrument reading, as determined by the 
method as specified in Sec. 63.180(b), that defines a leak is:
    (A) For agitators, an instrument reading of 10,000 parts per million 
or greater.
    (B) For pumps, an instrument reading of 2,000 parts per million or 
greater.
    (iii) Visual Inspections. Each pump and agitator shall be checked by 
visual inspection each calendar week for indications of liquids dripping 
from the pump or agitator seal. If there are indications of liquids 
dripping from the pump or agitator seal at the time of the weekly 
inspection, the owner or operator shall follow the procedure specified 
in either paragraph (c)(2)(iii)(A) or (B) of this section prior to the 
next weekly inspection.
    (A) The owner or operator shall monitor the pump or agitator by the 
method specified in Sec. 63.180(b). If the instrument reading indicates a 
leak as specified in paragraph (c)(2)(ii) of this section, a leak is 
detected.
    (B) The owner or operator shall eliminate the visual indications of 
liquids dripping.
    (3) Repair provisions.
    (i) When a leak is detected pursuant to paragraph (c)(2)(i), 
(c)(2)(iii)(A), (c)(5)(iv)(A), or (c)(5)(vi)(B) of this section, it 
shall be repaired as soon as practicable, but not later than 15 calendar 
days after it is detected, except as provided in paragraph (b)(4)(i) of 
this section.
    (ii) A first attempt at repair shall be made no later than 5 
calendar days after the leak is detected. First attempts at repair 
include, but are not limited to, the following practices where 
practicable:
    (A) Tightening of packing gland nuts.
    (B) Ensuring that the seal flush is operating at design pressure and 
temperature.
    (4) Calculation of percent leakers. (i) The owner or operator shall 
decide no later than the end of the first monitoring period what groups 
of processes will be developed. Once the owner or operator has decided, 
all subsequent percent calculations shall be made on the same basis.
    (ii) If, calculated on a 1-year rolling average, the greater of 
either 10 percent or three of the pumps in a group of processes leak, 
the owner or operator shall monitor each pump once per month, until the 
calculated 1-year rolling average value drops below 10 percent or three 
pumps, as applicable.
    (iii) The number of pumps in a group of processes shall be the sum 
of all the pumps in organic HAP service, except that pumps found leaking 
in a continuous process within 1 quarter after startup of the pump shall 
not count in the percent leaking pumps calculation for that one 
monitoring period only.
    (iv) Percent leaking pumps shall be determined by the following 
Equation 3:

%PL = [(PL--PS)/(PT--
PS)] x 100 (Eq. 3)

Where:
%PL = percent leaking pumps
PL = number of pumps found leaking as determined through 
periodic monitoring as required in paragraphs (c)(2)(i) and (ii) of this 
section.
PT = total pumps in organic HAP service, including those 
meeting the criteria in paragraphs (c)(5) and (6) of this section.
PS = number of pumps in a continuous process leaking within 1 
quarter of startup during the current monitoring period.

    (5) Exemptions. Each pump or agitator equipped with a dual 
mechanical seal system that includes a barrier fluid system is exempt 
from the requirements of paragraphs (c)(1) through

calendar week for indications of liquids dripping from the pump/agitator 
seal. If there are indications of liquids dripping from the pump or 
agitator seal at the time of the weekly inspection, the owner or 
operator shall follow the procedures specified in either paragraph 
(c)(5)(iv)(A) or (B) of this section prior to the next required 
inspection.
    (A) The owner or operator shall monitor the pump or agitator using 
the method specified in Sec. 63.180(b) to determine if there is a leak of 
organic HAP in the barrier fluid. If the instrument reading indicates a 
leak, as specified in paragraph (c)(2)(ii) of this section, a leak is 
detected.
    (B) The owner or operator shall eliminate the visual indications of 
liquids dripping.
    (v) Each sensor as described in paragraph (c)(5)(iii) of this

shaft penetrating the pump/agitator housing is exempt from the 
requirements of paragraphs (c)(1) through (3) of this section.
    (7) Any pump/agitator equipped with a closed-vent system capable of 
capturing and transporting any leakage from the seal or seals back to 
the process or to a control device that complies with the requirements 
of paragraph (b)(4)(ii) of this section is exempt from the requirements 
of paragraphs (c)(2) through (5) of this section.
    (8) Any pump/agitator that is located within the boundary of an 
unmanned plant site is exempt from the weekly visual inspection 
requirement of paragraphs (c)(2)(iii) and (c)(5)(iv) of this section, 
and the daily requirements of paragraph (c)(5)(v) of this section, 
provided that each pump/agitator is visually inspected as often as

flow through the open-ended valve or line, or during maintenance or 
repair. The cap, blind flange, plug, or second valve shall be in

[[Page 97]]

place within 1 hour of cessation of operations requiring process fluid 
flow through the open-ended valve or line, or within 1 hour of cessation 
of maintenance or repair. The owner or operator is not required to keep 
a record documenting compliance with the 1-hour requirement.
    (2) Each open-ended valve or line equipped with a second valve shall 
be operated in a manner such that the valve on the process fluid end is 
closed before the second valve is closed.
    (3) When a double block and bleed system is being used, the bleed 
valve or line may remain open during operations that require venting the 
line between the block valves but shall comply with paragraph (d)(1) of 
this section at all other times.

paragraphs (d)(1) through (d)(3) of this section are exempt from the 
requirements of paragraphs (d)(1) through (d)(3) of this section.
    (e) Standards: Valves in Gas/Vapor Service and in Light Liquid 
Service. (1) The provisions of this section apply to valves that are 
either in gas organic HAP service or in light liquid organic HAP 
service.
    (2) For existing and new affected sources, all valves subject to 
this section shall be monitored, except as provided in paragraph (f) of 
this section and in Sec. 63.177, by no later than 1 year after the 
compliance date.
    (3) Monitoring. The owner or operator of a source subject to this 
section shall monitor all valves, except as provided in paragraph (f) of 
this section and in Sec. 63.177, at the intervals specified in paragraph 
(e)(4) of this section and shall comply with all other provisions of 
this section, except as provided in paragraph (b)(4)(i) of this section, 
Secs. 63.178 and 63.179.
    (i) The valves shall be monitored to detect leaks by the method 
specified in Sec. 63.180(b).
    (ii) An instrument reading of 500 parts per million or greater 
defines a leak.
    (4) Subsequent monitoring frequencies. After conducting the initial 
survey required in paragraph (e)(2) of this section, the owner or 
operator shall monitor valves for leaks at the intervals specified 
below:
    (i) For a group of processes with 2 percent or greater leaking 
valves, calculated according to paragraph (e)(6) of this section, the 
owner or operator shall monitor each valve once per month, except as 
specified in paragraph (e)(9) of this section.
    (ii) For a group of processes with less than 2 percent leaking 
valves, the owner or operator shall monitor each valve once each 
quarter, except as provided in paragraphs (e)(4)(iii) through (e)(4)(v) 
of this section.
    (iii) For a group of processes with less than 1 percent leaking 
valves, the owner or operator may elect to monitor each valve once every 
2 quarters.
    (iv) For a group of processes with less than 0.5 percent leaking 
valves, the owner or operator may elect to monitor each valve once every 
4 quarters.
    (v) For a group of processes with less than 0.25 percent leaking 
valves, the owner or operator may elect to monitor each valve once every 
2 years.
    (5) Calculation of percent leakers. For a group of processes to 
which this subpart applies, an owner or operator may choose to subdivide 
the valves in the applicable group of processes and apply the provisions 
of paragraph (e)(4) of this section to each subgroup. If the owner or 
operator elects to subdivide the valves in the applicable group of 
processes, then the provisions of paragraphs (e)(5)(i) through 
(e)(5)(viii) of this section apply.
    (i) The overall performance of total valves in the applicable group 
of processes must be less than 2 percent leaking valves, as detected 
according to

[[Page 98]]

paragraphs (e)(3) (i) and (ii) of this section and as calculated 
according to paragraphs (e)(6) (ii) and (iii) of this section.
    (ii) The initial assignment or subsequent reassignment of valves to 
subgroups shall be governed by the provisions of paragraphs (e)(5)(ii) 
(A) through (C) of this section.
    (A) The owner or operator shall determine which valves are assigned 
to each subgroup. Valves with less than 1 year of monitoring data or 
valves not monitored within the last 12 months must be placed initially 
into the most frequently monitored subgroup until at least 1 year of 
monitoring data has been obtained.
    (B) Any valve or group of valves can be reassigned from a less 
frequently monitored subgroup to a more frequently monitored subgroup 
provided that the valves to be reassigned were monitored during the most 
recent monitoring period for the less frequently monitored subgroup. The 
monitoring results must be included with the less frequently monitored 
subgroup's monitoring event and associated next percent leaking valves 
calculation for that group.
    (C) Any valve or group of valves can be reassigned from a more 
frequently monitored subgroup to a less frequently monitored subgroup 
provided that the valves to be reassigned have not leaked for the period 
of the less frequently monitored subgroup (e.g., for the last 12 months, 
if the valve or group of valves is to be reassigned to a subgroup being 
monitored annually). Nonrepairable valves may not be reassigned to a 
less frequently monitored subgroup.
    (iii) The owner or operator shall determine every 6 months if the 
overall performance of total valves in the applicable group of processes 
is less than 2 percent leaking valves and so indicate the performance in 
the next periodic report. If the overall performance of total valves in 
the applicable group of processes is 2 percent leaking valves or 
greater, the owner or operator shall revert to the program required in 
paragraphs (e)(2) through (e)(4) of this section. The overall 
performance of total valves in the applicable group of processes shall 
be calculated as a weighted average of the percent leaking valves of 
each subgroup according to the following Equation 4:
[GRAPHIC] [TIFF OMITTED] TR21SE98.002

where:

%VLO = overall performance of total valves in the applicable 
process or group of processes
%VLi = percent leaking valves in subgroup i, most recent 
value calculated according to the procedures in paragraphs (e)(6)(ii) 
and (iii) of this section
Vi = number of valves in subgroup i

    (iv) Records. In addition to records required by paragraph (g) of 
this section, the owner or operator shall maintain records specified in 
paragraphs (e)(5)(iv)(A) through (D) of this section.
    (A) Which valves are assigned to each subgroup,
    (B) Monitoring results and calculations made for each subgroup for 
each monitoring period,
    (C) Which valves are reassigned and when they were reassigned, and
    (D) The results of the semiannual overall performance calculation 
required in paragraph (e)(5)(iii) of this section.
    (v) The owner or operator shall notify the Administrator no later 
than 30 days prior to the beginning of the next monitoring period of the 
decision to subgroup valves. The notification shall identify the 
participating processes and the valves assigned to each subgroup.
    (vi) Semiannual reports. In addition to the information required by 
paragraph (h)(3) of this section, the owner or operator shall submit in 
the periodic reports the information specified in paragraphs 
(e)(5)(vi)(A) and (B) of this section.
    (A) Valve reassignments occurring during the reporting period, and
    (B) Results of the semiannual overall performance calculation 
required by paragraph (e)(5)(iii) of this section.

[[Page 99]]

    (vii) To determine the monitoring frequency for each subgroup, the 
calculation procedures of paragraph (e)(6)(iii) of this section shall be 
used.
    (viii) Except for the overall performance calculations required by 
paragraphs (e)(5)(i) and (e)(5)(iii) of this section, each subgroup 
shall be treated as if it were a process for the purposes of applying 
the provisions of this section.
    (6)(i) The owner or operator shall decide no later than the 
implementation date of this subpart or upon revision of an operating 
permit how to group the processes. Once the owner or operator has 
decided, all subsequent percentage calculations shall be made on the 
same basis.
    (ii) Percent leaking valves for each group of processes or subgroup 
shall be determined by the following Equation 5:

%VL = [VL/VT] x 100  (Eq. 5)

Where:

%VL = percent leaking valves as determined through periodic 
monitoring required in paragraphs (e)(2) through (4) of this section.
VT = total valves monitored, in a monitoring period excluding 
valves monitored as required by (e)(7)(iii) of this section

    (iii) When determining monitoring frequency for each group of 
processes or subgroup subject to monthly, quarterly, or semiannual 
monitoring frequencies, the percent leaking valves shall be the 
arithmetic average of the percent leaking valves from the last two 
monitoring periods. When determining monitoring frequency for each group 
of processes or subgroup subject to annual or biennial (once every 2 
years) monitoring frequencies, the percent leaking valves shall be the 
arithmetic average of the percent leaking valves from the last three 
monitoring periods.
    (iv)(A) Nonrepairable valves shall be included in the calculation of 
percent leaking valves the first time the valve is identified as leaking 
and nonrepairable and as required to comply with paragraph (e)(6)(iv)(B) 
of this section. Otherwise, a number of nonrepairable valves (identified 
and included in the percent leaking calculation in a previous period) up 
to a maximum of 1 percent of the total number of valves in organic HAP 
service at a process may be excluded from calculation of percent leaking 
valves for subsequent monitoring periods.
    (B) If the number of nonrepairable valves exceeds 1 percent of the 
total number of valves in organic HAP service at a process, the number 
of nonrepairable valves exceeding 1 percent of the total number of 
valves in organic HAP service shall be included in the calculation of 
percent leaking valves.
    (7) Repair provisions. (i) When a leak is detected, it shall be 
repaired as soon as practicable, but no later than 15 calendar days 
after the leak is detected, except as provided in paragraph (b)(4)(i)) 
of this section.
    (ii) A first attempt at repair shall be made no later than 5 
calendar days after each leak is detected.
    (iii) When a leak is repaired, the valve shall be monitored at least 
once within the first 3 months after its repair. Days that the valve is 
not in organic HAP service shall not be considered part of this 3 month 
period. The monitoring required by this paragraph is in addition to the 
monitoring required to satisfy the definitions of ``repaired'' and 
``first attempt at repair.''
    (A) The monitoring shall be conducted as specified in Sec. 63.180(b) 
and (c) as appropriate to determine whether the valve has resumed 
leaking.
    (B) Periodic monitoring required by paragraphs (e)(2) through (4) of 
this section may be used to satisfy the requirements of paragraph 
(e)(7)(iii) of this section, if the timing of the monitoring period 
coincides with the time specified in paragraph (e)(7)(iii) of this 
section. Alternatively, other monitoring may be performed to satisfy the 
requirements of paragraph (e)(7)(iii) of this section, regardless of 
whether the timing of the monitoring period for periodic monitoring 
coincides with the time specified in paragraph (e)(7)(iii) of this 
section.
    (C) If a leak is detected by monitoring that is conducted pursuant 
to paragraph (e)(7)(iii) of this section, the owner or operator shall 
follow the provisions of paragraphs (e)(7)(iii)(C)(1) and (2) of this 
section to determine whether that valve must be counted as

[[Page 100]]

a leaking valve for purposes of paragraph (e)(6) of this section.
    (1) If the owner or operator elects to use periodic monitoring 
required by paragraphs (e)(2) through (4) of this section to satisfy the 
requirements of paragraph (e)(7)(iii) of this section, then the valve 
shall be counted as a leaking valve.
    (2) If the owner or operator elects to use other monitoring prior to 
the periodic monitoring required by paragraphs (e)(2) through (4) of 
this section to satisfy the requirements of paragraph (e)(7)(iii) of 
this section, then the valve shall be counted as a leaking valve unless 
it is repaired and shown by periodic monitoring not to be leaking.
    (8) First attempts at repair include, but are not limited to, the 
following practices where practicable:
    (i) Tightening of bonnet bolts,
    (ii) Replacement of bonnet bolts,
    (iii) Tightening of packing gland nuts, and
    (iv) Injection of lubricant into lubricated packing.
    (9) Any equipment located at a plant site with fewer than 250 valves 
in organic HAP service in the affected source is exempt from the 
requirements for monthly monitoring specified in paragraph (e)(4)(i) of 
this section. Instead, the owner or operator shall monitor each valve in 
organic HAP service for leaks once each quarter, or comply with 
paragraph (e)(4)(iii), (iv), or (v) of this section, except as provided 
in paragraph (f) of this section.
    (f) Unsafe to monitor/inspect, difficult to monitor/inspect, and 
inaccessible equipment. (1) Equipment that is designated as unsafe to 
monitor, unsafe to inspect, difficult to monitor, difficult to inspect, 
or inaccessible is exempt from the monitoring requirements as specified 
in paragraphs (f)(1)(i) through (iv) of this section provided the owner 
or operator meets the requirements specified in paragraph (f)(2), (3), 
or (4) of this section, as applicable. All equipment must be assigned to 
a group of processes. Ceramic or ceramic-lined connectors are subject to 
the same requirements as inaccessible connectors.
    (i) For pumps and agitators, paragraphs (c)(2), (3), and (4) of this 
section do not apply.
    (ii) For valves, paragraphs (e)(2) through (7) of this section do 
not apply.
    (iii) For connectors, Sec. 63.174(b) through (e) and paragraphs 
(b)(4)(iii)(B) through (F) of this section do not apply.
    (iv) For closed-vent systems, Sec. 63.172(f)(1) and (2) and Sec. 63.172(g) 
do not apply.
    (2) Equipment that is unsafe to monitor or unsafe to inspect. (i) 
Valves, connectors, agitators, and pumps may be designated as unsafe to 
monitor if the owner or operator determines that monitoring personnel 
would be exposed to an immediate danger as a consequence of complying 
with the monitoring requirements referred to in paragraphs (f)(1)(i) 
through (iii) of this section.
    (ii) Any part of a closed-vent system may be designated as unsafe to 
inspect if the owner or operator determines that monitoring personnel 
would be exposed to an immediate danger as a consequence of complying 
with the monitoring requirements referred to in paragraph (f)(1)(iv) of 
this section.
    (iii) The owner or operator of equipment that is designated as 
unsafe to monitor must have a written plan that requires monitoring of 
the equipment as frequently as practicable during safe to monitor times, 
but not more frequently than the periodic monitoring schedule otherwise 
applicable to the group of processes in which the equipment is located.
    (iv) For any parts of a closed-vent system designated as unsafe to 
inspect, the owner or operator must have a written plan that requires 
inspection of the closed-vent systems as frequently as practicable 
during safe to inspect times, but not more frequently than annually.
    (3) Equipment that is difficult to monitor or difficult to inspect. 
(i) A valve, agitator, or pump may be designated as difficult to monitor 
if the owner or operator determines that the valve, agitator, or pump 
cannot be monitored without elevating the monitoring personnel more than 
2 meters above a support surface, or it is not accessible in a

[[Page 101]]

safe manner when it is in organic HAP service.
    (ii) Any part of a closed-vent system may be designated as difficult 
to inspect if the owner or operator determines that the equipment cannot 
be inspected without elevating the monitoring personnel more than 2 
meters above a support surface, or it is not accessible in a safe manner 
when it is in organic HAP service.
    (iii) At an existing source, any valve, agitator or pump within a 
group of processes that meets the criteria of paragraph (f)(3)(i) of 
this section may be designated as difficult to monitor, and any parts of 
a closed-vent system that meet the requirements of paragraph (f)(3)(ii) 
of this section may be designated as difficult to inspect. At a new 
affected source, an owner or operator may designate no more than 3 
percent of valves as difficult to monitor.
    (iv) The owner or operator of valves, agitators, or pumps designated 
as difficult to monitor must have a written plan that requires 
monitoring of the equipment at least once per calendar year or on the 
periodic monitoring schedule otherwise applicable to the group of 
processes in which the equipment is located, whichever is less frequent. 
For any part of a closed-vent system designated as difficult to inspect, 
the owner or operator must have a written plan that requires inspection 
of the closed-vent system at least once every 5 years.
    (4) Inaccessible, ceramic, or ceramic-lined connectors. (i) A

monitor probe;
    (C) Obstructed by equipment or piping that prevents access to the 
connector by a monitor probe;
    (D) Unable to be reached from a wheeled scissor-lift or hydraulic-
type scaffold which would allow access to equipment up to 7.6 meters (25 
feet) above the ground; or
    (E) Not able to be accessed at any time in a safe manner to perform 
monitoring. Unsafe access includes, but is not limited to, the use of a 
wheeled scissor-lift on unstable or uneven terrain, the use of a 
motorized man-lift basket in areas where an ignition potential exists, 
or access would require near proximity to hazards such as electrical 
lines, or would risk damage to equipment.
    (ii) A connector may be designated as inaccessible if it would 
require elevating the monitoring personnel more than 2 meters above a 
permanent support surface or would require the erection of scaffold.
    (iii) At an existing source, any connector that meets the criteria 
of paragraph (f)(4)(i) or (ii) of this section may be designated as 
inaccessible. At a new affected source, an owner or operator may 
designate no more than 3 percent of connectors as inaccessible.
    (iv) If any inaccessible, ceramic, or ceramic-lined connector is 
observed by visual, audible, olfactory, or other means to be leaking, 
the leak shall be repaired as soon as practicable, but no later than 15 
calendar days after the leak is detected, except as provided in 
paragraph (b)(4)(i) of this section.
    (v) Any connector that is inaccessible or that is ceramic or 
ceramic-lined is exempt from the recordkeeping and reporting 
requirements of paragraphs (g) and (h) of this section.
    (g) Recordkeeping Requirements. (1) An owner or operator of more 
than one group of processes subject to the provisions of this section 
may comply with the recordkeeping requirements for the groups of 
processes in one recordkeeping system if the system identifies with each 
record the program being implemented (e.g., quarterly monitoring) for 
each type of equipment. All records and information required by this

repaired within 15 calendar days after discovery of the leak.
    (A) The owner or operator may develop a written procedure that 
identifies the conditions that justify a delay of repair. The written 
procedures shall be included either as part of the startup/shutdown/
malfunction plan, required by Sec. 63.1259(a)(3), or in a separate document 
that is maintained at the plant site. Reasons for delay of repair may be 
documented by citing the relevant sections of the written procedure.
    (B) If delay of repair was caused by depletion of stocked parts, 
there must be documentation that the spare parts were sufficiently 
stocked onsite before depletion and the reason for depletion.
    (vi) If repairs were delayed, dates of process shutdowns that occur 
while the equipment is unrepaired.
