TITLE 40 - PROTECTION OF ENVIRONMENT
CHAPTER I - ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 65 - CONSOLIDATED FEDERAL AIR RULE--Table of Contents
Subpart F - Equipment Leaks
Sec. 65.108 Standards: Connectors in gas/vapor service and in light liquid service.
(a) Compliance schedule. Except as allowed in Sec.
65.102(b) or as specified in paragraph (e) of this section, the owner or
operator shall monitor all connectors in each process unit initially for
leaks by either 12 months after the implementation date as specified in
Sec. 65.1(f) or 12 months after initial startup, whichever is
later. If all connectors in each process unit have been monitored for
leaks prior to the implementation date specified in Sec.
65.1(f), no initial monitoring is required provided either no process
changes have been made since the monitoring or the owner or operator can
determine that the results of the monitoring, with or without
adjustments, reliably demonstrate compliance despite process changes. If
required to monitor because of a process change, the owner or operator
is required to monitor only those connectors involved in the process
change.
(b) Leak detection. Except as allowed in Sec. 65.102(b) or
as specified in paragraph (e) of this section, the owner or operator
shall monitor all connectors in gas/vapor and light liquid service as
specified in paragraphs (a) and (b)(3) of this section.
(1) Monitoring method. The connectors shall be monitored to detect
leaks by the method specified in Sec. 65.104(b) and (c).
(2) Instrument reading that defines a leak. If an instrument reading
greater than or equal to 500 parts per million is measured, a leak is
detected.
(3) Monitoring periods. The owner or operator shall perform
monitoring, subsequent to the initial monitoring required in paragraph
(a) of this section, as specified in paragraphs (b)(3)(i)
[[Page 81]]
through (iii) of this section, and shall comply with the requirements of
paragraphs (b)(3)(iv) and (v) of this section. The required period in
which monitoring must be conducted shall be determined from paragraphs
(b)(3)(i) through (iii) of this section using the monitoring results
from the preceding monitoring period. The percent leaking connectors
shall be calculated as specified in paragraph (c) of this subpart.
(i) If the percent leaking connectors in the process unit was
greater than or equal to 0.5 percent, then monitor within 12 months (1
year).
(ii) If the percent leaking connectors in the process unit was
greater than or equal to 0.25 percent but less than 0.5 percent, then
monitor within 4 years. An owner or operator may comply with the
requirements of paragraph (b)(3)(ii) of this section by monitoring at
least 40 percent of the connectors within 2 years of the start of the
monitoring period, provided all connectors have been monitored by the
end of the 4-year monitoring period.
(iii) If the percent leaking connectors in the process unit was less
than 0.25 percent, then monitor as provided in paragraph (b)(3)(iii)(A)
of this section and either paragraph (b)(3)(iii)(B) or (C) of this
section, as appropriate.
(A) An owner or operator shall monitor at least 50 percent of the
connectors within 4 years of the start of the monitoring period.
(B) If the percent leaking connectors calculated from the monitoring
results in paragraph (b)(3)(iii)(A) of this section is greater than or
equal to 0.35 percent of the monitored connectors, the owner or operator
shall monitor as soon as practical, but within the next 6 months, all
connectors that have not yet been monitored during the monitoring
period. At the conclusion of monitoring, a new monitoring period shall
be started pursuant to paragraph (b)(3) of this section, based on the
percent leaking connectors of the total monitored connectors.
(C) If the percent leaking connectors calculated from the monitoring
results in paragraph (b)(3)(iii)(A) of this section is less than 0.35
percent of the monitored connectors, the owner or operator shall monitor
all connectors that have not yet been monitored within 8 years of the
start of the monitoring period.
(iv) If, during the monitoring conducted pursuant to paragraphs
(b)(3)(i) through (iii) of this section, a connector is found to be
leaking, it shall be re-monitored once within 90 days after repair to
confirm that it is not leaking.
(v) The owner or operator shall keep a record of the start date and
end date of each monitoring period under this section for each process
unit.
(c) Percent leaking connectors calculation. For use in determining
the monitoring frequency as specified in paragraphs (a) and (b)(3) of
this section, the percent leaking connectors as used in paragraphs (a)
and (b)(3) of this section shall be calculated by using Equation 108-1
of this section:
[GRAPHIC] [TIFF OMITTED] TR14DE00.006
Where:
%CL = Percent leaking connectors as determined through
periodic monitoring required in paragraphs (a) and (b)(3)(i) through
(b)(3)(iii) of this section.
CL = Number of connectors measured at 500 parts per million
or greater by the method specified in Sec. 65.104(b).
Ct = Total number of monitored connectors in the process
unit.
(d) Leak repair. If a leak is detected pursuant to paragraphs (a)
and (b) of this section, then the leak shall be repaired using the
procedures in Sec. 65.105, as applicable.
(e) Special provisions for connectors. - (1) Unsafe-to-monitor
connectors. Any connector that is designated, as described in
Sec. 65.103(c)(1), as an unsafe-to-monitor connector is exempt
from the requirements of paragraphs (a) and (b) of this section and the
owner or operator shall monitor according to the written plan specified
in Sec. 65.103(c)(4).
(2) Inaccessible, ceramic, or ceramic-lined connectors. (i) Any
connector that is inaccessible or that is ceramic or ceramic-lined (for
example, porcelain, glass, or glass-lined), is exempt from the
monitoring requirements of paragraphs (a) and (b) of this section and
from the recordkeeping and reporting requirements of
Sec.Sec. 65.119 and 65.120. An inaccessible
connector is one that meets any of the following provisions, as
applicable:
[[Page 82]]
(A) Buried;
(B) Insulated in a manner that prevents access to the connector by 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 that would allow access to connectors up to 7.6 meters (25
feet) above the ground;
(E) Inaccessible because it would require elevating the monitoring
personnel more than 2 meters (7 feet) above a permanent support surface
or would require the erection of scaffold;
(F) 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) If any inaccessible, ceramic, or ceramic-lined connector is
observed by visual, audible, olfactory, or other means to be leaking,
the visual, audible, olfactory, or other indications of a leak to the
atmosphere shall be eliminated as soon as practical.
(3) Connectors referenced from 40 CFR part 60, subpart VV or 40 CFR
part 61, subpart V. For sources referenced to this part from 40 CFR part
61, subpart VV, or from 40 CFR part 61, subpart V, connectors are exempt
from the requirements of paragraphs (a) through (d) of this section and
the owner or operator shall comply with the following paragraphs:
(i) Connectors shall be monitored within 5 days by the method
specified in Sec. 65.104(b) and (c) if evidence of a potential
leak is found by visual, audible, olfactory, or any other detection
method.
(ii) If an instrument reading of 500 parts per million or greater is
measured, a leak is detected.
(iii) When a leak is detected, it shall be repaired using the
procedures in Sec. 65.105, as applicable.
