II. Background Information
On September 4, 2007 (72 FR 50716), EPA proposed several actions
under section 112 of the Clean Air Act (CAA) with respect to petroleum
refineries subject to the 1995 Refinery MACT 1 Rule (40 CFR part 63,
subpart CC). Please refer to the 2007 proposal for additional
background material. See 72 FR 50717-18. In response to comments
received on the 2007 proposed rule, EPA further evaluated that proposal
and is now supplementing its proposal with respect to cooling towers
and storage vessels. In addition, as part of this notice, we are
providing proposed revisions to the regulatory text to clarify and
correct definitions, tables, and regulatory citations.
III. Summary of Supplemental Proposal
A. What are the proposed requirements to meet CAA sections 112(f)(2)
and (d)(6) for Group 1 storage vessels?
In the September 2007 proposed rule, EPA initially proposed two
regulatory options for storage vessels under CAA sections 112(f)(2) and
(d)(6): Option 1 would require no revisions to the Refinery MACT 1 rule
and Option 2 would add the requirements in 40 CFR 63.119(c)(2)(ix) and
(x) for slotted guide poles on existing external floating roof (EFR)
storage vessels (Refinery MACT 1 currently provides an exemption from
these requirements for existing storage vessels). For more detail on
the proposed options, please see 72 FR 50726-27.
Many commenters agreed that, of EPA's proposed options, Option 2,
controls for slotted guide poles, is an appropriate and cost-effective
level of control. However, several commenters supporting Option 2
requested that EPA revise the regulatory text associated with Option 2
to use clear terminology consistent with the most recent rules and
technologies for storage vessels, i.e., the rules at 40 CFR part 63,
subpart WW and the Storage Tank Emission Reduction Partnership Program
(STERPP) (described at 65 FR 19891). Specifically, commenters noted
that subpart WW and STERPP include clearer descriptions and definitions
of control options and provide clear and specific criteria for
requirements such as the required height of a pole float and the
position of a gasket.
Based on our review of public comments and subsequent analysis, we
are proposing an additional option under CAA sections 112(f)(2) and
(d)(6) for storage vessels. Specifically, we are proposing to remove
the exemptions for existing EFR storage vessels and amend the
requirements for all Group 1 storage vessels to be consistent with, and
refer directly to, the requirements of 40 CFR part 63, subpart WW. The
subpart WW requirements include the requirements for fitting controls
on slotted guide poles, which were originally proposed under Option 2,
as well as additional requirements for fittings for unslotted guide
poles and other openings on EFR storage vessels. The proposed
amendments also include the inspection, recordkeeping, and reporting
requirements in subpart WW to account for the additional requirements
for fitting controls for EFR storage vessels. It should be noted that,
while subpart WW was preferred by the commenters and its stringency is
equivalent to the HON, the existing 40 CFR part 63, subpart CC does not
require all the specific tank fitting control requirements in the HON.
While proposed Option 2 in the September 2007 proposal included some
tank fitting control requirements not currently included in subpart CC,
Option 2 did not include all of the tank fitting control requirements
in the HON and subpart WW. Consequently, by proposing to require
compliance with subpart WW, we are proposing full tank
[[Page 66696]]
fitting controls for Group 1 storage vessels, and, therefore, today's
proposed amendments are more stringent than the existing subpart CC
rules and the subpart CC amendments proposed in September 2007.
The subpart WW requirements are being proposed because, in addition
to providing clearer language for fitting controls, they provide an
ample margin of safety to protect public health. This option reduces
hazardous air pollutants (HAP) emissions and risks beyond the current
maximum achievable control technology (MACT) standard using controls
that are technically and economically feasible and that pose no adverse
environmental impacts. We estimate that these changes would reduce the
number of people at cancer risk greater than 1-in-1 million by 20,000
individuals and the cancer incidence by 0.002--0.003 cases per year
(i.e., prevent one cancer case every 400 years). This option would
reduce emissions of volatile organic compounds (VOC) by 14,800 tons per
year (tpy). Reducing VOC provides the added benefit of reducing ambient
concentrations of ozone and may reduce fine particulate matter. The
annualized cost impacts of this option are estimated to be a cost
savings of $6.8 million. Our economic analysis (summarized later in
this preamble) indicates that this cost will have little impact on the
price and output of petroleum products.
Under this option, we are proposing that the owner or operator of
an existing Group 1 storage vessel comply with the requirements in
subpart WW of this part no later than 90 days after promulgation of
these amendments. As provided in 40 CFR part 63, subpart WW, and for
the reasons provided in Section IV, we are proposing that retrofitting
floating roof tanks with the guide pole controls and certain other
requirements is not required until the next time the vessel is emptied
and degassed, or 10 years from the promulgation date of the final
standards, whichever is sooner.
B. What are the proposed requirements for cooling towers under CAA
sections 112(d)(2) and (f)(2)?
Under CAA sections 112(d)(2) and (d)(3), we proposed work practice
standards for cooling towers that would require the owner or operator
of a new or existing source to monitor for leaks in the cooling tower
return lines from heat exchangers in organic HAP service (i.e., lines
that contain or contact fluids with 5 weight percent or greater of
total organic HAP listed in Table 1 of the rule) and, where leaks are
detected, to repair such leaks within a specified period of time. We
proposed two options for new and existing sources, one based on the
MACT floor analysis that accompanied the proposal, i.e., the average
emissions limitations achieved by the top 12 percent of the affected
sources, and the other based on an analysis of beyond-the-floor
techniques. For more detail on those options, please see 72 FR 50722-
24.
In response to public comments that the terms used in the proposed
cooling tower requirements needed to be defined and should focus on
heat exchange systems, we are proposing to add several definitions to
clarify the cooling tower monitoring requirements. We are proposing
that the cooling tower requirements would apply to each ``heat exchange
system.'' A ``heat exchange system'' means a device or series of
devices used to transfer heat from process fluids to water without
intentional direct contact of the process fluid with the water (i.e.,
non-contact heat exchangers) and to transport and/or cool the water in
a closed loop recirculation system (cooling tower system) or a once
through system (e.g., river or pond water). A ``heat exchange system''
can include one or more heat exchangers, all water lines to and from
the heat exchanger(s), and, for recirculating systems, the cooling
tower or towers that receive water from the heat exchanger(s).
In response to public comments that our floor analysis did not
include existing State standards, we collected new information on
existing State and local cooling towers provisions and revised our MACT
floor analysis. More detail regarding the development of the revised
MACT floor for existing and new sources based on review of these
existing State requirements is provided in Section IV.B. of this
preamble and in the docket memorandum entitled ``Cooling Towers:
Control Alternatives and Impact Estimates'' (EPA-HQ-OAR-2003-0146). The
revised proposed requirements are described below and are based on the
revised MACT floor determination. Control techniques considered as
beyond-the-floor options are described in Section IV.B of this
preamble; we are not proposing any of these options because they were
determined not to be cost-effective.
We are proposing that owners and operators of heat exchange systems
that are in organic HAP service at new and existing sources would be
required to conduct monthly sampling and analyses using the Texas
Commission on Environmental Quality's (TCEQ) Modified El Paso method,
Revision Number One, dated January 2003.\1\ For existing sources,
monthly cooling tower monitoring would begin within 18 months of
promulgation of the final amendments. For new sources, monthly cooling
tower monitoring would begin upon start-up or on the date of
promulgation of these amendments, whichever is later. For existing
sources, a leak would be defined as 6.2 parts per million by volume
(ppmv) total strippable VOC in the stripping gas collected via the
Modified El Paso method. For new sources, a leak would be defined as
3.1 ppmv total strippable VOC collected via the Modified El Paso
method. The proposed amendments would require the repair of leaks in
heat exchangers in organic HAP service within 45 days of the sampling
event in which the leak was detected, unless a delay in repair is
allowed. Delay in repair of the leak would be allowed until the next
shutdown if the repair of the leak would require the process unit
served by the leaking heat exchanger to be shut down and the total
strippable VOC concentration is less than 62 ppmv. Delay in repair of
the leak would also be allowed for up to 120 days if the total
strippable VOC concentration is less than 62 ppmv and if critical parts
or personnel are not available. The owner or operator would be required
to continue monthly monitoring and repair the heat exchanger within 45
days if sampling results show that the leak exceeds 62 ppmv total
strippable VOC. Within the first 3 years after promulgation of these
amendments, delay in repair of a leak would also be allowed if the leak
exceeds 62 ppmv total strippable VOC and the repair of the leak would
require the process unit served by the leaking heat exchanger to be
shut down and a shutdown is planned within 60 days or if critical parts
or personnel are not available. Starting 3 years after promulgation of
these amendments, delay of repair beyond 45 days would not be allowed
if the leak exceeds 62 ppmv total strippable VOC.

Determination of Volatile Organic Compound Emissions from Water
Sources,'' Revision Number One, dated January 2003, Sampling
Procedures Manual, Appendix P: Cooling Tower Monitoring, prepared by
Texas Commission on Environmental Quality, January 31, 2003
(incorporated by reference-see Sec. 63.14).
---------------------------------------------------------------------------
Sampling for leaks would be conducted either at individual heat
exchanger return lines (i.e., water lines returning the water from the
heat exchanger to the cooling tower) or the combined cooling tower
inlet water location. That is, if the cooling tower services multiple
heat exchangers, the
[[Page 66697]]
owner or operator may elect to monitor only the heat exchangers ``in
organic HAP service'' or monitor at the combined cooling tower inlet.
If a leak is detected at the combined cooling tower inlet, the owner or
operator may elect to fix the leak regardless of its location or begin
monitoring at each heat exchanger ``in organic HAP service'' to
document that the leak is not originating from a heat exchanger ``in
organic HAP service.''
All new or existing refineries with a heat exchange system ``in
organic HAP service'' would be required to maintain records of the heat
exchangers in organic HAP service, the cooling towers associated with
heat exchangers in organic HAP service, monthly monitoring results, and
information for any delays in repair of a leak.
C. What other revisions and clarifications are we proposing?
In the September 2007 proposal, we proposed to amend Table 6 to 40
CFR part 63, subpart CC (General Provisions Applicability to Subpart
CC) to bring the table up-to-date with current requirements of the
General Provisions and clarify certain requirements. In conjunction
with the publication of Table 6 in the proposal, we erroneously
included a Table 11. We are clarifying that we are not proposing to
include Table 11 and, thus, do not plan to include it as part of the
final rule.
We received public comments that methyl ethyl ketone (also known as
2-butanone) has been delisted as a HAP. We are, therefore, proposing to
revise Table 1 to delete methyl ethyl ketone from the HAP listed in
Table 1.
We also received several public comments noting that cross-
references to other subparts should be updated. Therefore, we are also
proposing amendments to correct cross-references to subparts R and Y of
part 63 in the rule text, as well as to correct the recordkeeping and
reporting requirement cross-references in Tables 4 and 5 of subpart CC
to part 63. We are also proposing to clarify applicability sections by
specifying the promulgation date of the original subpart CC. Finally,
we are proposing amendments to clarify how owners and operators should
comply with overlapping standards for equipment leaks. These proposed
amendments are included to clarify the requirements of subpart CC.
IV. Rationale for Supplemental Proposed Amendments
A. Storage Vessels
In response to public comments on the original proposal, we revised
and updated the analysis of the options we proposed in September 2007.
We also evaluated a wider range of control options, such as the
requirements included in the Generic Storage Vessel MACT (40 CFR part
63, subpart WW) and STERPP, as well as other specific controls
suggested by the commenters. A detailed explanation of our impacts
analysis for each of the options described in this section is provided
in ``Storage Vessels: Revised Control Options and Impact Estimates'' in
Docket ID No. EPA-HQ-OAR-2003-0146.
The storage vessel controls in 40 CFR part 63, subpart WW and for
STERPP include several compliance options for controlling slotted guide
poles as well as requirements for additional fitting controls on other
EFR deck openings. We determined that, based on emission modeling runs
using a model gasoline storage vessel, the STERPP and subpart WW
requirements for slotted guide poles achieve the same or better
emission reduction efficiencies as the originally proposed Option 2 for
Group 1 storage vessels. And, while additional deck fitting controls on
EFR storage vessels contained in the STERPP and subpart WW provide only
a tenth of the emission reductions as the guide pole controls, these
controls (primarily use of gaskets) are inexpensive. As seen in Table 1
of this preamble, our cost analysis indicates that these fitting
controls are cost-effective. Therefore, we are proposing an additional
option that would require these additional fitting controls for
existing Group 1 storage vessels covered by Refinery MACT 1.
Based on our evaluation of the STERPP and 40 CFR part 63, subpart
WW control requirements, we determined that those standards require
solid, or unslotted, guide poles to be gasketed and have a wiper
system, and we evaluated the impacts of also adding these requirements
to Refinery MACT 1. We determined that, provided the retrofits could be
performed without additional emissions and cost associated with an
unplanned emptying and degassing of the storage vessel (i.e., during a
turnaround or when the vessel is taken out of service for maintenance/
repair), the control requirements for solid guide poles were cost-
effective. That is, over a 10-year cycle using a 7-percent annual
interest rate, these controls yield a net cost savings (from reduced
product losses). The combination of additional deck fitting controls
and full guide pole controls is presented in Table 1 as ``full deck and
guide pole controls.'' Consequently, we are proposing as an additional
option to amend Refinery MACT 1 to refer directly to the storage vessel
control requirements in subpart WW. As the cost-effectiveness of the
control retrofits are predicated on a lack of additional emissions and
cost associated with emptying and degassing the storage vessel, we are
providing up to 10 years for compliance with these requirements as
provided for in 40 CFR 63.1063(a)(ix) of subpart WW. Because these
controls are cost-effective and incrementally reduce public exposure,
we believe this option, in addition to the two options proposed
earlier, would provide an ample margin of safety and meet the
requirements of the technology review.

B. Cooling Towers
To respond to public comments that our floor analysis did not
include existing State standards, we collected additional information
on cooling tower requirements for multiple petroleum refineries in
several States. Using these data, we reanalyzed the MACT floor for new
and existing sources and identified 39 petroleum refineries in
California, Illinois, Indiana, Louisiana, Minnesota, and Texas with
permit requirements for HAP and/or VOC in cooling tower return water
along with cooling tower monitoring requirements. We note that the
permit requirements are based on calculated emission estimates using
the water recirculation rates and monitored concentrations in the
cooling waters. Consequently, the permit requirements effectively
define a maximum allowable concentration limit of strippable organics
in the cooling water so that the effective leak definition could be
determined for each cooling tower. We further note that no refineries
directly measure cooling tower emissions, and we reaffirm our
conclusion that cooling tower work practice standards are appropriate
because the emissions are not emitted through a stack or other
conveyance and are, therefore, not practically measurable.
We ranked cooling tower requirements based on the projected
emissions that would occur given the specific cooling tower monitoring
provision. Based on preliminary calculations performed using the
cooling tower impacts model (see ``Cooling Towers: Control Alternatives
and Impact Estimates'' memorandum in Docket ID No. EPA-HQ-OAR-2003-
0146), the leak definition was the primary factor influencing the
emissions limitations achieved by a cooling tower monitoring program;
the second most important factor was the specification of time frames
for completing repairs and provisions or limitations for delay of
repair. Monitoring frequency, while a contributing factor to overall
cooling tower emissions performance, was not as important as the leak
definition and specified repair deadlines. We selected the 6th
percentile cooling tower as indicative of the average emission
limitation achieved by the best performing 12 percent of cooling
towers. Based on this, we determined that the MACT floor for cooling
towers at existing sources is cooling water sampling on a monthly basis
for total strippable VOC compounds, where a leak is defined as 6.2 ppmv
of total strippable VOC compounds in the stripping air of the TCEQ
Modified El Paso method. We note that this leak definition is
equivalent to the controlled emission factor in AP-42,\2\ and that many
refineries use this controlled emission factor when estimating and
reporting their cooling tower emissions.

---------------------------------------------------------------------------
Additionally, based on this MACT floor analysis, we determined that
the existing source MACT floor repair requirements include identifying
the source of the leak and repairing within 45 days of originally
finding the leak. Delay of repair is allowed under certain conditions
if the total strippable VOC is less than 62 ppmv, but is not allowed if
the total strippable VOC concentration is equal to or greater than 62
ppmv. When total strippable VOC is less than 62 ppmv, delay of repair
is allowed for up to 120 days if the necessary equipment, parts, or
personnel are not available, and delay of repair is allowed until the
next shutdown if a shutdown is required to effect the repair. For delay
of repair, the refinery must document the basis for the delay,
including the reason for delaying repair, provide a schedule for
completing the repair, and determine the emissions of HAP during the
time duration of the delay.
While these delay of repair provisions are based on our MACT floor
assessment, we note that some of the permits for facilities in the top
12 percent provide time to implement the monitoring requirements before
the ban on delay of repairs for leaks exceeding 62 ppmv becomes
effective. We recognize that when facilities first start to monitor
their cooling towers, the likelihood of finding large leaks is much
greater than after a monthly monitoring program has been implemented.
As
[[Page 66699]]
such, when first implementing the monthly monitoring, they may identify
heat exchange systems that have leaks exceeding 62 ppmv, but may not
have the spare parts or adequate time to plan for the repair of the
heat exchange system that would typically be available after the
monthly monitoring program has been in place for some time. As such, we
propose to phase-in the cooling tower requirements for existing
sources. The monitoring and leak repair provisions for existing sources
would become effective no later than 18 months after promulgation of
the final rule; however, the delay of repair is allowed regardless of
the leak size for the first 18 months of the monitoring program. No
later than 3 years from the promulgation date of these amendments, no
delay of repair is allowed for leaks exceeding 62 ppmv total strippable
VOC.
The new source MACT for cooling towers must be no less stringent
than the best-performing refinery cooling towers. In our ranking of the
information collected on monitoring requirements, the best-performing
cooling tower has a leak definition of 3.1 ppmv of strippable total
organics as methane in the stripping air using monthly Modified El Paso
method sampling and analysis. As such, the MACT floor for cooling
towers at new sources is monthly cooling water sampling for total
strippable VOC, where a leak is defined as 3.1 ppmv of total strippable
VOC in the stripping air using the Modified El Paso method. The repair
requirements for the top-performing cooling towers include identifying
the source of the leak and repairing within 45 days of originally
finding the leak. Delay of repair for the top-performing cooling towers
is allowed if strippable total VOC concentration is less than 62 ppmv,
but not allowed if strippable total VOC concentration is equal to or
greater than 62 ppmv. That is, the delay of repair provisions for the
new source MACT floor cooling towers are the same as those for an
existing source MACT floor cooling towers.
We revised our cooling tower emissions estimates since the 2007
proposal based on reanalysis of the emissions inventory information
obtained from TCEQ for the 2004 reporting year, as well as other
information collected regarding cooling tower monitoring provisions and
flow data from the Industrial Cooling Tower National Emission Standards
for Hazardous Air Pollutants (NESHAP). Model cooling tower emissions
for each refinery facility in the nation were estimated based on crude
throughput data which were used to estimate total cooling water flow
rates and generic refinery stream VOC and HAP compositions. These data
were used with controlled and uncontrolled AP-42 emission factors for
VOC emissions from cooling towers and the fraction of cooling towers
with specific monitoring requirements to estimate cooling tower
baseline HAP emissions. The nationwide baseline HAP emissions were
estimated at 770 tpy as compared to a baseline estimate of greater than
3,000 tpy in the 2007 proposal. These emissions compare reasonably well
with the organic HAP emissions estimate based on the TCEQ data, as
revised, to correct a reporting error identified by a public commenter.
From the updated TCEQ 2004 database, we estimated the organic HAP
emissions from cooling towers to be 95 tpy for Texas refineries alone.
Extrapolation of the Texas data based on direct crude distillation
capacity provides a nationwide emissions estimate for cooling towers of
352 tpy of organic HAP. However, refineries in Texas had the most
stringent cooling tower monitoring provisions of any of the State
requirements, and the Texas refineries used the controlled AP-42
emission factor for their cooling tower emission estimates. If the non-
Texas refineries operate nearer the uncontrolled AP-42 emission factor,
nationwide cooling tower emissions are projected to be 2,300 tpy of
organic HAP. While there is significant uncertainty in the actual
cooling tower emission estimate, the projected baseline emissions fall
easily within the range expected based on reanalysis of the Texas
dataset.
Following reanalysis of the MACT floor for cooling towers, we also
conducted a revised cost analysis for the MACT floor level of control.
We included costs for a strippable total VOC monitoring system,
increased the time needed for sampling and analysis for each cooling
tower, and added costs for sampling and analysis for specific heat
exchangers for triggered monitoring following identification of a
cooling tower leak. We also increased the cost associated with
repairing a leaking heat exchanger. The cost-effectiveness of the MACT
floor control for cooling towers at both new and existing sources was
approximately $4,700 per ton of HAP reduced when considering product
recovery credits and approximately $8,200 per ton when product recovery
credits were not included. See Table 3 of this preamble.
We also evaluated the costs of applying the new source leak
definition to existing sources and implementing this option with
continuous strippable total VOC monitoring systems as a beyond-the-MACT
floor control options. The first alternative reduces an additional 40
tpy of HAP emissions at an incremental cost-effectiveness of almost
$6,000 per ton on HAP emission reduction and the second option with
continuous monitoring reduces HAP emissions by an additional 10 tpy and
has an incremental cost-effectiveness of almost $600,000 per ton of HAP
reduced.
Based on this analysis, we conclude that the beyond-the-MACT floor
control options are not cost-effective and we are proposing standards
for cooling towers commensurate with the MACT floor determinations
under CAA sections 112(d)(2) and (3). Further, we are proposing that
the MACT floor level of control also provides an ample margin of safety
and satisfies the risk review requirements under CAA section 112(f)(2).
For more information on the costing methodology, see Table 3 of this
preamble and the ``Cooling Towers: Control Alternatives and Impact
Estimates'' memorandum in the docket (Docket ID No. EPA-HQ-OAR-2003-
0146).

proposed ample margin of safety determination under CAA section
112(f)(2). Specifically, the table presents the pre-MACT risk, the risk
associated with the proposed MACT floor which is the baseline for our
residual risk analysis, and the risk reduction for the first beyond the

V. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
action is a ``significant regulatory action'' because it may raise
novel legal or policy issues. Accordingly, EPA submitted this action to
OMB for review under Executive Order 12866, and any changes made in
response to OMB recommendations have been documented in the docket for
this action.
B. Paperwork Reduction Act
The information collection requirements in this proposed rule have
been submitted for approval to the OMB under the Paperwork Reduction
Act, 44 U.S.C. 3501, et seq. The Information Collection Request (ICR)
document prepared by EPA has been assigned ICR number 2334.01.
The information requirements in the proposed amendments include
monitoring, recordkeeping, and reporting provisions for storage vessels
and cooling towers. Owners or operators of storage vessels must comply
with the inspection, recordkeeping, and reporting requirements in 40
CFR part 63, subpart WW. Owners or operators of cooling towers must
conduct monthly monitoring of each heat exchanger to identify and
repair leaks. Records of monitoring and repair data also must be kept.
All respondents must submit one-time notifications and semiannual
compliance reports.
The information collection requirements in the proposed amendments
are needed by EPA and delegated authorities to determine that
compliance has been achieved. The recordkeeping and reporting
requirements in this proposed rule are based on the information
collection requirements in the part 63 General Provisions (40 CFR part
63, subpart A). The recordkeeping and reporting requirements in the
General Provisions are mandatory pursuant to section 114 of the CAA (42
U.S.C. 7414). All information submitted to EPA pursuant to the
information collection requirements for which a claim of
confidentiality is made is safeguarded according to CAA section 114(c)
and the Agency's implementing regulations at 40 CFR part 2, subpart B.
The annual burden for this information collection averaged over the
first 3 years of this ICR is estimated to total 13,714 labor hours per
year at a cost of $1,056,081 for one new refinery and 153 existing
refineries. The average annual reporting burden is 353.9 labor hours
for 205.9 total annual responses; the average annual burden per
response is 1.72 hours. Responses include notifications of compliance
status for cooling towers and storage vessels at new and existing
refineries, notification of initial startup for storage vessels at one
new refinery, and semiannual compliance reports containing information
on cooling towers and storage vessels at new and existing refineries.
Capital/startup costs are estimated at $16,306,000. The operation and
maintenance costs associated with the proposed rule amendments are
estimated at $61,711. Burden is defined at 5 CFR 1320.3(b).
An agency may not conduct or sponsor, and a person is not required
to respond to, a collection of information unless it displays a
currently valid OMB control number. The OMB control numbers for EPA's
regulations in 40 CFR are listed in 40 CFR part 9.
To comment on the EPA's need for this information, the accuracy of
the provided burden estimates, and any suggested methods for minimizing
respondent burden, including the use of automated collection
techniques, EPA has established a public docket for this action, which
includes this ICR, under Docket ID No. EPA-HQ-OAR-2003-0146. Submit any
comments related to the ICR for the proposed rule to EPA and OMB. See
the ADDRESSES section at the beginning of this preamble for where to
submit comments to EPA. Send comments to OMB at the Office of
Information and Regulatory Affairs, Office of Management and Budget,
725 17th Street, NW., Washington, DC
[[Page 66701]]
20503, Attention: Desk Office for EPA. Because OMB is required to make
a decision concerning the ICR between 30 and 60 days after November 10,
2008, a comment to OMB is best assured of having its full effect if OMB
receives it by December 10, 2008. The final rule will respond to any
OMB or public comments on the information collection requirements
contained in this proposal.
C. Regulatory Flexibility Act
The Regulatory Flexibility Act generally requires an agency to
prepare a regulatory flexibility analysis of any rule subject to notice
and comment rulemaking requirements under the Administrative Procedure
Act or any other statute unless the agency certifies that the rule will
not have a significant economic impact on a substantial number of small
entities. Small entities include small businesses, small organizations,
and small governmental jurisdictions.
For the purposes of assessing the impacts of this proposed rule on
small entities, small entity is defined as: (1) A small business that
meets the Small Business Administration size standards for small
businesses at 13 CFR 121.201 (a firm having no more than 1,500
employees; (2) a small governmental jurisdiction that is a government
of a city, county, town, school district, or special district with a
population of less than 50,000; and (3) a small organization that is
any not-for-profit enterprise which is independently owned and operated
and is not dominant in its field.
After considering the economic impacts of this proposed rule on
small entities, I certify that this action will not have a significant
economic impact on a substantial number of small entities. Based on our
economic impact analysis, the proposed amendments will result in a
nationwide net annualized cost savings of about $3.8 million due to a
return of about $10.5 million per year from reductions in product
losses. Only one oil refining entity would incur net annualized costs
as a result of the proposed amendments; all other refinery entities
would have net savings. This refinery entity is a small parent entity.
Net annualized costs for this affected small entity are well below 0.01
percent of their revenue; therefore, no ``significant'' adverse
economic impacts are expected for any small entity. Thus, the costs
associated with the proposed amendments will not result in any
``significant'' adverse economic impact for any small entity. For more
information, please refer to the economic impact analysis that is in
the docket for this rulemaking.
Although the proposed rule will not have a significant economic
impact on a substantial number of small entities, we nonetheless tried
to reduce the impact of the proposed rule on small entities. We held
meetings with industry trade associations and company representatives
to discuss the proposed rule and have included provisions for small
facilities that address their concerns. We continue to be interested in
the potential impacts of the proposed action on small entities and
welcome comments on issues related to such impacts.
D. Unfunded Mandates Reform Act
This action contains no Federal mandates under the provisions of
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C.
1531-1538 for State, local, or tribal governments or the private
sector.
The proposed rule does not contain a Federal mandate that may
result in expenditures of $100 million or more for State, local, and
tribal governments, in the aggregate, or to the private sector in any
one year. As discussed earlier in this preamble, these amendments
result in nationwide net savings to the private sector. Therefore, the
proposed rule is not subject to the requirements of sections 202 or 205
of the UMRA.
This proposed rule is also not subject to the requirements of
section 203 of UMRA because it contains no regulatory requirements that
might significantly or uniquely affect small governments. The proposed
amendments contain no requirements that apply to such governments, and
impose no obligations upon them.
E. Executive Order 13132: Federalism
Executive Order 13132, entitled Federalism (64 FR 43255, August 10,
1999), requires EPA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' is defined in the
Executive Order to include regulations that have ``substantial direct
effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.''
The proposed amendments do not have federalism implications. They
would not have substantial direct effects on the States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government, as specified in Executive Order 13132. The proposed
amendments add control and monitoring requirements. They do not modify
existing responsibilities or create new responsibilities among EPA
Regional offices, States, or local enforcement agencies. Thus,
Executive Order 13132 does not apply to the proposed amendments.
In the spirit of Executive Order 13132, and consistent with EPA
policy to promote communications between EPA and State and local
governments, EPA specifically solicits comment on this proposed rule
from State and local officials.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications, as specified in
Executive Order 13175 (65 FR 67249, November 9, 2000). The proposed
amendments will not have substantial direct effects on tribal
governments, on the relationship between the Federal Government and
Indian tribes, or on the distribution of power and responsibilities
between the Federal government and Indian tribes, as specified in
Executive Order 13175. The proposed amendments impose no requirements
on tribal governments. Thus, Executive Order 13175 does not apply to
this action.
EPA specifically solicits additional comment on this proposed
action From tribal officials.
G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
This action is not subject to Executive Order 13045 (62 FR 19885,
April 23, 1997) because it is not economically significant as defined
in Executive Order 12866, and because the Agency does not believe the
environmental health or safety risks addressed by this action present a
disproportionate risk to children. This action's health and risk
assessments are contained in the revised Residual Risk Assessment for
MACT 1 Petroleum Refining Sources, which is available in the docket.
H. Executive Order 13211: Actions That Significantly Affect Energy
Supply, Distribution, or Use
The proposed amendments are not a ``significant energy action'' as
defined in Executive Order 13211 (66 FR 28355, May 22, 2001) because
they are not likely to have a significant adverse effect on the supply,
distribution, or use of energy. Further, we have concluded that the
proposed amendments are not likely to have any adverse energy effects
[[Page 66702]]
because they result in overall savings due to product recovery.
I. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act (NTTAA) of 1995 (Pub. L. No. 104-113, 15 U.S.C. 272 note) directs
EPA to use voluntary consensus standards (VCS) in its regulatory
activities, unless to do so would be inconsistent with applicable law
or otherwise impractical. VCS are technical standards (e.g., materials
specifications, test methods, sampling procedures, and business
practices) that are developed or adopted by VCS bodies. NTTAA directs
EPA to provide Congress, through OMB, explanations when the Agency does
not use available and applicable VCS.
This proposed rule involves technical standards. EPA proposes to
use ``Air Stripping Method (Modified El Paso Method) for Determination
of Volatile Organic Compound Emissions from Water Sources,'' Revision
Number One, dated January 2003, and will incorporate the method by
reference (see 40 CFR 63.14). This method is available at http://
www.tceq.state.tx.us/assets/public/implementation/air/sip/sipdocs/2002-
12-HGB/02046sipapp_ado.pdf , or from the Texas Commission on
Environmental Quality (TCEQ) Library, Post Office Box 13087, Austin,
Texas, 78711-3087, telephone number (512) 239-0028. This method was
chosen based on public comments regarding the sampling and analysis of
air emissions from cooling towers, and is required in these proposed
amendments instead of the originally proposed requirements in 40 CFR
61.355(c) for water sample collection, and EPA Method 8260B for
analysis of water samples taken from cooling tower return lines.
This TCEQ method utilizes a dynamic or flow-through system for air
stripping a sample of the water and analyzing the resultant off-gases
for VOC using a common flame ionization detector (FID) analyzer. While
direct water analyses, such as purge and trap analyses of water samples
utilizing gas chromatography and/or mass spectrometry techniques, have
been shown to be effective for cooling tower measurements of heavier
molecular weight organic compounds with relatively high boiling points,
it has been determined that this approach may be ineffective for
capture and measurement of VOC with lower boiling points, such as
ethylene, propylene, 1,3-butadiene, and butenes. The VOC with a low
molecular weight and boiling point are generally lost in the sample
collection step of purge/trap type analyses. Consequently, this TCEQ
air stripping method is used for cooling tower and other applicable
water matrix emission measurements when VOC with boiling points below
140o F need to be evaluated.
Under 40 CFR 63.7(f) and 40 CFR 63.8(f) of subpart A of the General
Provisions, a source may apply to EPA for permission to use alternative
test methods or alternative monitoring requirements in place of any
required testing methods, performance specifications, or procedures in
the proposed amendments.
EPA welcomes comments on this aspect of the proposed rulemaking
and, specifically, invites the public to identify potentially
applicable voluntary consensus standards and to explain why such
standards should be used in the regulations.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
Executive Order 12898 (59 FR 7629, February 16, 1994) establishes
Federal executive policy on environmental justice. Its main provision
directs Federal agencies, to the greatest extent practicable and
permitted by law, to make environmental justice part of their mission
by identifying and addressing, as appropriate, disproportionately high
and adverse human health or environmental effects of their programs,
policies, and activities on minority populations and low-income
populations in the United States.
EPA has determined that these proposed amendments will not have
disproportionately high and adverse human health or environmental
effects on minority or low-income populations because they increase the
level of environmental protection for all affected populations without
having any disproportionately high and adverse human health or
environmental effects on any population, including any minority or low-
income population.
The proposed amendments add new control requirements to established
national standards for petroleum refineries to address risk remaining
after implementation of the 1995 standards and, thus, decrease the
amount of toxic emissions to which all affected populations are
exposed.

13. Sections 63.654 and 63.655 are redesignated as Sec. Sec.
63.655 and 63.656.
14. A new Sec. 63.654 is added to read as follows:
Sec. 63.654 Heat exchange systems.
(a) Except as specified in paragraph (b) of this section, the owner
or operator of a heat exchange system that meets the criteria in Sec.
63.640(c)(8) must comply with the requirements of paragraphs (c)
through (g) of this section.
(b) A heat exchange system is exempt from the requirements in
paragraphs (c) through (g) of this section if it meets any one of the
criteria in paragraphs (b)(1) through (3) of this section.
(1) The heat exchange system operates with the minimum pressure on
the cooling water side at least 35 kilopascals greater than the maximum
pressure on the process side.
(2) The heat exchange system contains an intervening cooling fluid,
containing less than 5 percent by weight of total HAP listed in Table 1
to this subpart, between the process and the cooling water. This
intervening fluid must serve to isolate the cooling water from the
process fluid and must not be sent through a cooling tower or
discharged. For purposes of this section, discharge does not include
emptying for maintenance purposes.
(3) The heat exchange system cools process fluids that contain less
than 5 percent by weight of total HAP listed in Table 1 to this subpart
(i.e., the heat exchange system is not in organic HAP service as
defined in this subpart).
(c) You must perform monthly monitoring to identify leaks of total
strippable volatile organic compound (VOC) from each heat exchange
system subject to the requirements of this subpart according to the
procedures in paragraphs (c)(1) and (2) of this section.
(1) Collect and analyze a sample from each cooling tower return
line prior to exposure to air for each heat exchanger system in organic
HAP service or from each heat exchanger exit line for each heat
exchanger in organic HAP service within that heat exchange system to
determine the total strippable VOC concentration (as methane) from the
air stripping testing system using ``Air Stripping Method (Modified El
Paso Method) for Determination of Volatile Organic Compound Emissions
from Water Sources'' Revision Number One, dated January 2003, Sampling
Procedures Manual, Appendix P: Cooling Tower Monitoring, prepared by
Texas Commission on Environmental Quality, January 31, 2003
(incorporated by reference-see Sec. 63.14).
(2) For a heat exchange system at an existing source, a leak is a
total strippable VOC concentration (as methane) in the stripping gas of
6.2 ppmv or greater. For a heat exchange system at a new source, a leak
is a total strippable VOC concentration (as methane) in the stripping
gas of 3.1 ppmv or greater.
(d) If a leak is detected, you must repair the leak to reduce the
measured concentration to below the applicable action level as soon as
practicable, but no later than 45 days after identifying the leak,
except as specified in paragraphs (e) and (f). Actions that can
[[Page 66707]]
be taken to achieve repair include but are not limited to:
(1) Physical modifications to the leaking heat exchanger, such as
welding the leak or replacing a tube;
(2) Blocking the leaking tube within the heat exchanger;
(3) Changing the pressure so that water flows into the process
fluid;
(4) Replacing the heat exchanger or heat exchanger bundle; or
(5) Isolating, bypassing, or otherwise removing the leaking heat
exchanger from service until it is otherwise repaired.
(e) If you detect a leak when monitoring a cooling tower return
line under paragraph (c)(1), you may conduct additional monitoring to
identify leaks of total strippable VOC emissions using Modified El Paso
method from each heat exchanger in organic HAP service associated with
the heat exchange system for which the leak was detected. If the
additional monitoring shows that the total strippable VOC concentration
in the stripped air at the heat exchanger exit line for each heat
exchanger in organic HAP service is less than 6.2 ppmv for existing
sources or less than 3.1 ppmv for new sources, the heat exchange system
is excluded from repair requirements in paragraph (d).
(f) You may delay the repair of a leaking heat exchanger when you
meet one of the conditions in paragraphs (f)(1) through (3) of this
section. You must determine if a delay of repair is necessary as soon
as practicable, but no later than 45 days after first identifying the
leak.
(1) If the repair is technically infeasible without a shutdown and
the total strippable VOC concentration (as methane) is initially and
remains less than 62 ppmv for all monthly monitoring periods during the
delay of repair, you may delay repair until the next scheduled shutdown
of the heat exchange system. If, during subsequent monthly monitoring,
the total strippable VOC concentration (as methane) is 62 ppmv or
greater, you must repair the leak within 30 days of the monitoring
event in which the leak was equal to or exceeded 62 ppmv total
strippable VOC (as methane), except as provided in paragraph (f)(3) of
this section.
(2) If the necessary equipment, parts, or personnel are not
available and the total strippable VOC concentration (as methane) is
initially and remains less than 62 ppmv for all monthly monitoring
periods during the delay of repair, you may delay the repair for a
maximum of 120 calendar days. You must demonstrate that the necessary
equipment, parts, or personnel were not available. If, during
subsequent monthly monitoring, the total strippable VOC concentration
(as methane) is 62 ppmv or greater, you must repair the leak within 30
days of the monitoring event in which the leak was equal to or exceeded
62 ppmv total strippable VOC (as methane), except as provided in
paragraph (f)(3) of this section, or the original 120 day delay of
repair deadline, whichever occurs first.
(3) Prior to [3 years after the date of publication of the final
amendments in the Federal Register], you may delay the repair of a heat
exchanger for which the total strippable VOC concentration (as methane)
is 62 ppmv or greater as provided in paragraphs (f)(3)(i) through
(f)(3)(iii) of this section. On and after the date [3 years after
publication of the final amendments in the Federal Register], you are
not allowed to delay the repair of a heat exchanger for which the total
strippable VOC concentration (as methane) is 62 ppmv or greater.
(i) If the repair is technically infeasible without a shutdown and
a shutdown of the unit is scheduled within 60 days of determining a
delay of repair is necessary.
(ii) If the necessary equipment, parts, or personnel are not
available, may delay the repair for a maximum of 120 calendar days.
(iii) If the repair is technically infeasible without a shutdown
and a shutdown of the unit will cause more emissions than the delay of
repair.
