Federal Standards for Marine Tank Vessel Loading Operations and 
National Emission Standards for Hazardous Air Pollutants for Marine 
Tank Vessel Loading Operations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This action promulgates standards under section 183(f) of the 
Clean Air Act (the Act) and requires reasonably available control 
technology (RACT) to limit air emissions of volatile organic compounds 
(VOC) and hazardous air pollutants (HAP) from new and existing marine 
tank vessel loading operations. VOC emissions, together with nitrogen 
oxides are precursors to the formation of tropospheric ozone, which can 
impair lung capacity, cause eye, nose and throat irritation, timber and 
other valuable crops such as soybeans and cotton. The health effects of 
exposure to HAPs can include cancer, respiratory irritation and damage 
to the nervous system. An additional set of standards promulgate 
national emission standards for hazardous air pollutants (NESHAP) under 
section 112 of the Act for marine tank vessel loading operations and 
require existing and new major sources to control emissions using 
maximum achievable control technology (MACT) to control HAP.

EFFECTIVE DATE: This regulation is effective September 19, 1995. See 
Supplementary Information section concerning judicial review.

I. The Standards

    A summary of today's final standards is listed in Table 1. Included 
in this table are applicability cutoffs based on annual throughput 
(under section 183(f)) and HAP emissions (under section 112), 
separation of marine tank vessel loading operations at petroleum 
refineries (which are now included under the petroleum refineries 
source category), and emission standards based on subcategory 
determinations for offshore terminals and the Alyeska Pipeline Service 
Company's (APSC's) Valdez Marine Terminal (VMT). The promulgated 
regulations allow for several alternative compliance technologies to 
allow owners or operators maximum compliance flexibility.

--------------------------------------------------------------------------------------------------------------------------------------------------------

    Sources required to reduce emissions are also required to monitor 
the performance of control technology installed to achieve the required 
emissions reductions. Baseline parameters may be established by owners 
or operators during initial performance tests, or continuous emissions 
monitoring devices may be used to provide indicators of performance. 
The baseline parameters may be based on manufacturer's recommended 
operating parameters or other parameters selected by the source and 
approved by the Administrator. Sources are also required to develop and 
implement an operation and maintenance plan that describes a program of 
corrective action for varying (i.e., exceeding baseline parameters) air 
pollution control equipment and monitoring equipment used to comply 
with these emissions standards. This plan includes operating parameters 
that shall be monitored and recorded as indicators of proper operation 
of the air pollution control devices.
    In developing these final monitoring requirements and compliance 
provisions, the Agency has provided significant flexibility to owners 
or operators of sources required to reduce emissions in regard to 
selecting monitoring protocols, yet has assured compliance with the 
standards. Compliance is assured through reporting and recordkeeping 
requirements that specify annual reports of system performance. This 
reporting interval is compressed to semi-annual for sources that 
experience excess emissions.
    Owners or operators of all marine tank vessel loading operations 
subject to the federal standards promulgated 

[[Page 48390]]
under section 183(f) of the Act (RACT sources) are required to commence 
construction of its vapor collection system and air pollution control 
device(s) within 2 years from September 19, 1995. These RACT sources 
are required to complete the installation of the control technology 
needed to comply with the standards within 3 years from September 19, 
1995. Owners or operators of new RACT sources with an initial startup 
after September 21, 1998 are required to comply with all requirements 
upon startup. A RACT source may request a waiver of final compliance 
for up to 1 year if it can prove that the additional time is necessary 
for the installation of controls.
    Owners or operators of marine tank vessel loading operations 
subject only to the requirements promulgated under section 112(d) of 
the Act (MACT standards) are required to install the control technology 
needed to comply with the standards within 4 years from September 19, 
1995. Owners or operators of new MACT-only sources with initial startup 
after September 20, 1999 are required to comply with all requirements 
upon startup.
    The VMT owners or operators are required to install the control 
technology needed to comply with the standards within 30 months from 
September 19, 1995.

II. Summary of Impacts

    These standards will reduce nationwide emissions of hazardous air 
pollutants (HAP) from marine tank vessel loading operations by 
approximately 4,150 Mg (4,565 tons) after 1999 compared to the 
emissions that would result in the absence of the standards. These 
standards will reduce emissions of volatile organic compounds (VOC) 
from marine tank vessel loading operations by approximately 39,000 Mg 
(42,900 tons) after 1999 compared to the emissions that would result in 
the absence of the standards. No significant adverse secondary air, 
water, solid waste, or energy impacts are anticipated from the 
promulgation of these standards.
    The implementation of this regulation is expected to result in 
nationwide annualized costs for existing marine tank vessel loading 
operations of $60 million to $100 million beyond baseline based on an 
analysis of applying controls to all existing facilities not currently 
controlled to the level of the standards. Nationwide capital costs 
expected to result from these regulations are approximately $266 
million to $440 million.
    As discussed in this preamble under Regulatory Flexibility Act 
Compliance, the economic impact analysis performed for this rulemaking 
showed that the estimated maximum price increases for the affected 
products varied, but were not large (less than 1%). These price-
increase estimates reflect the control cost increases for transporting 
crude and products. Because these increases are small and because the 
elasticities of demand for petroleum products are small, estimated 
percent output reductions were minimal. Correspondingly, estimated 
employment reductions were also relatively small.
    Potentially significant economic impacts on some of the smaller 
affected terminal operations were identified, although the decision not 
to require emission controls for existing smaller operations greatly 
reduces the potential for adverse economic impacts on small terminal 
operations. These potential impacts would result from the high per 
barrel control cost differential between the smaller and larger 
terminal operations that would need to control emissions. Some of these 
smaller terminal operations, to the extent that they are competing with 
nearby larger or unaffected terminal operations, could have had 
difficulty raising prices to cover cost increases and could have been 
significantly adversely impacted by this rule.
    The potential economic impact on marine tank vessel owners was 
substantially reduced because of the decision not to require emission 
controls on small existing terminals in this rulemaking. Because only a 
small percentage of U.S. marine transported volume of products will be 
impacted by the standard, only a relatively small percentage of U.S. 
marine tank vessels will need to retrofit. Thus, only the vessels that 
will need the least cost to retrofit (most likely the larger, newer, 
double-skin vessels) will do so, leading to some degree of dedicated 
service. It is expected that vessel owners that do retrofit will be 
able to pass most retrofit costs forward in terms of higher prices.

III. Significant Changes to the Proposed Standards

    Proposed standards for marine tank vessel loading operations were 
published in the Federal Register on May 13, 1994 (59 FR 25004). Under 
section 183(f) of the Act, the proposed rule would have required a 98 
percent reduction in emissions (or a 95 percent reduction, if recovery 
techniques were used) from marine tank vessel loading and unloading 
operations that load either 100 million barrels per year of crude oil 
or 5 million barrels per year of gasoline. Sources would have had 2 
years to comply with these RACT standards. Under section 112(d) of the 
Act, the proposed rule also would have required owners or operators of 
major sources that emit 1 ton per year or more of HAP from marine tank 
vessel loading and unloading operations to reduce total HAP emissions 
by at least 93 percent. Sources would have had 3 years to comply with 
these MACT standards. The control devices used to meet these standards 
were required to be operated at 98 and 95 percent efficiencies for 
combustion and recovery control technologies respectively. The EPA also 
proposed to regulate emissions from ballasting.
    Three alternatives were proposed to ensure vessel tightness: (1) 
Pressure test the vessel, (2) perform a leak test on all components 
using Method 21 of appendix A of 40 CFR part 60, or (3) load the vessel 
at less than atmospheric pressure.
    Proposed monitoring requirements required owners or operators to 
monitor any valves that could divert flow from a control device if 
those bypass valves could not be secured. Monitoring criteria were also 
proposed for combustion devices, carbon adsorbers, condensers, 
absorbers, and flares. Owners or operators were generally required to 
establish operating parameters during an initial performance test and 
then monitor combustion temperature for combustion devices, VOC 
concentration in the exhaust stream for carbon adsorbers, exhaust 
stream temperature for condensers, VOC outlet concentration for 
absorbers, and continuous presence of a flame and the vent stream flow 
for flares. Criteria to apply for and obtain approval for alternative 
monitoring criteria (and for alternative monitoring devices) were also 
specified in the proposed rule.
    Under the proposed rule, owners or operators of sources required to 
install controls would have had to fulfill the reporting and 
recordkeeping requirements of the part 63 General Provisions, including 
submittal of the following reports: (1) Initial notification that the 
source is subject to the standards, (2) notification of initial 
performance test, (3) initial notification of compliance status, (4) 
annual excess emissions and monitoring system performance report and/or 
summary report, and (5) an annual emissions estimation report. These 
sources would also have been required to maintain documentation that 
vessels loaded at the facility were vapor tight. All information was to 
have been made readily available to the Administrator or 

[[Page 48391]]
delegated State authority for a minimum of 5 years.
    In addition, the Agency requested comment on several issues, 
including the subcategorization of certain types of terminals. On 
August 31, 1994, the Agency published a notice reopening the comment 
period to request comment on amending the Marine Tank Vessel Loading 
and the Petroleum Refinery source categories to move marine terminals 
collocated at petroleum refineries to the Petroleum Refineries source 
category (59 FR 44955). On March 8, 1995, the Agency reopened the 
comment period to request comment on extending the proposed compliance 
dates (60 FR 12703).

A. Public Participation

    Prior to proposal of the standards, interested parties were advised 
by public notice in the Federal Register (56 FR 1186) of a meeting of 
the National Air Pollution Control Techniques Advisory Committee to 
discuss the regulation of this source category. This meeting was held 
on January 31, 1991. The meeting was open to the public, and each 
attendee was given an opportunity to comment on the standards 
recommended for proposal.
    The standards were proposed, and the preamble was published in the 
Federal Register on May 13, 1994 (59 FR 25004). The preamble to the 
proposed standards discussed the availability of the regulatory text 
and proposal TSD, which described the regulatory alternatives 
considered and the impacts of those alternatives. Public comments were 
solicited at the time of proposal, and copies of the regulatory text 
and TSD were distributed to interested parties. Electronic versions of 
the preamble, regulation, and TSD were made available to interested 
parties via the TTN (see ADDRESSES section of this preamble).
    To provide interested persons the opportunity for oral presentation 
of data, views, or arguments concerning the proposed standards, a 
public hearing was held on June 15, 1994 in Research Triangle Park, 
North Carolina. The public comment period was from May 13 to July 18, 
1994. The Agency also reopened the public comment period for specific 
comments on two occasions--August 31, 1994 (59 FR 44955) and March 8, 
1995 (60 FR 12723). In all, over 150 comment letters were received 
(including seven duplicates). Additional information received from 
interested parties but not submitted directly to the docket was 
included in the docket as additional comments on the proposed 
regulation. Information submitted after the close of the comment period 
is also included in the docket and may appear on the docket index as 
public comments in docket category IV-D. The comments have been 
carefully considered, and changes have been made to the proposed 
standards when determined by the Administrator to be appropriate.

B. Comments on the Proposed Standards

    Comments on the proposed standards were received from 143 
commenters composed mainly of States, environmental groups, private 
citizens, control device vendors, industry, and trade associations. A 
detailed discussion of these comments and responses can be found in the 
promulgation TSD, which is referred to in the ADDRESSES section of this 
preamble. The summary of comments and responses in the TSD serves as 
the basis for the revisions that have been made to the regulations 
between proposal and promulgation. Most of the comment letters 
contained multiple comments. A summary of the revisions to the 
regulations along with discussion of the comments on the major issues 
is provided below. In the TSD, the comments have been divided into the 
following areas:
    (1) Applicability of standards.
    (2) Inclusion of certain terminals with the petroleum refinery 
source category.
    (3) Subcategorization issues.
    (4) RACT/MACT.
    (5) Compliance schedule for Titles I and III standards.
    (6) Compliance, performance testing, and monitoring requirements.
    (7) Vapor tightness requirements.
    (8) Leak detection and repair.
    (9) Reporting and recordkeeping requirements.
    (10) General provisions interaction.
    (11) Wording of regulation.
    (12) Administrative record/sources of information.
    (13) Cost effectiveness/impacts.
    (14) Miscellaneous.
    (15) Comments on proposed appendices to 40 CFR part 64.

C. Significant Changes

    Several changes have been made since the proposal of these 
standards. The majority of the changes have been made to clarify 
portions of the rule that were unclear to the commenters. A summary of 
the major changes is presented below.
    (1) Removal of unloading operations (ballasting) from the source 
category. In the proposed rule, the Agency included regulations 
proscribing emissions from ballasting of vessels following unloading of 
vessels. Comments asserted that ballasting operations are performed by 
vessel operators, not by the regulated terminal sources. The Agency 
agrees with this interpretation of the affected source. The Agency also 
agrees that regulating ballasting operations would be difficult to 
enforce. The Agency's intent in prohibiting ballasting emissions in the 
proposed regulation was to provide a cross-reference with existing 
Coast Guard regulations addressing ballasting in vessels. The Coast 
Guard rules require vessels to have segregated ballast tanks for crude 
oil loadings. The Agency sees no benefit to restating Coast Guard 
requirements for ballasting. Moreover, EPA agrees that the relatively 
low amount of actual emissions associated with ballasting does not 
justify dual regulation of ballasting. As discussed in the proposal 
TSD, the total VOC emissions from crude oil tankship ballasting were 
estimated to be approximately 950 Mg/yr. Based on the portion of HAP in 
crude oil vapor, total HAP emissions from ballasting are less than 120 
Mg/yr. Ballasting emissions will diminish in the future because 
tankships built since 1980 are required by domestic law and 
international agreement to use segregated ballast tanks that do not 
emit vapors during ballasting. Therefore, in order to prevent confusion 
in the regulated community, the Agency does not address ballasting or 
bunkering emissions in the final regulation. The Agency defers to the 
U.S. Coast Guard's existing standards (33 CFR parts 155 and 157; and 46 
CFR parts 30 et al.).
    (2) Extension of the compliance schedule for section 183(f) 
(``Title I'') and section 112 (``Title III'') standards. In the 
proposed rule, EPA proposed to establish compliance deadlines of 2 
years for the section 183(f) standards, and 3 years for the section 112 
standards. The Agency received numerous comments regarding these 
schedules that stated the length of the compliance periods was 
insufficient to comply with the standards. Commenters noted that 
facilities' abilities to install pollution control devices are 
constrained by several factors, including the following: (1) The 
limited number of contractors experienced in installing control 
equipment in marine loading facilities; (2) the numerous facilities 
that will need to meet the standards at the same time; and (3) the lead 
time needed to meet permitting and safety requirements from permitting 
authorities and the U.S. Coast Guard.
    Commenters stated that EPA had discretion to extend the compliance 
period under section 183(f), noting the ambiguity of the term 
``effective date'' and that the evidence indicated that the proposed 
emission control technologies 

[[Page 48392]]
would not be ``reasonably available, considering costs, nonair-quality 
benefits, environmental impacts, energy requirements, and safety 
factors'' within 2 years. Commenters also noted that EPA had the 
authority to provide for a waiver of compliance with MACT standards 
under section 112 for up to 1 year if certain findings were made.
    On March 8, 1995, EPA reopened the comment period to receive more 
comments on the issue of whether the compliance periods for the RACT 
and MACT regulations should be extended. Numerous commenters indicated 
support for extending the compliance periods, generally reiterating the 
views expressed in earlier comments. Some commenters also pointed out 
that greater environmental benefits can sometimes be obtained by 
granting longer compliance periods, which can allow for better 
designed, more robust, safer and more advanced technologies, and in 
this instance, could result in greater use of recovery technologies 
(rather than incineration). Commenters also noted that previous 
attempts by States to regulate tank vessel loading in less than 3 years 
resulted in the need for numerous waivers as it became clear that the 
deadlines could not be met. One commenter provided a list of several 
marine loading terminals in California that had installed emission 
control equipment and indicated that almost all of these installation 
projects took at least 3 years to complete.
    The Agency agrees with the commenters that permitting and safety 
approvals from permitting authorities and the Coast Guard, the dearth 
of skilled engineering and construction firms, and the history of 
facilities being unable to comply with existing regulations compels the 
Agency to extend the date for full compliance with the RACT and MACT 
rules. In these final standards, EPA allows sources regulated under 
section 183(f) 3 years to be in full compliance with the emission 
control requirements promulgated under section 183(f). In addition, 
RACT sources may request a waiver of up to 1 year to achieve full 
compliance with the requirements if they can show that the additional 
period is necessary for the installation of controls. The Agency 
believes that this result is consistent with section 183(f). Section 
183(f) requires the application of ``reasonably available'' control 
technology, considering costs, any non-air quality benefits, 
environmental impacts, energy requirements, and safety factors. The 
overwhelming evidence received by the Agency indicates that most, if 
not all, sources that must install emission control devices cannot do 
so within 2 years. States that have attempted to enforce such a 
requirement have been forced to provide waivers to the regulated 
sources. Given the relative scarcity of qualified contractors and the 
permitting and other requirements necessary for such construction, it 
is clear that the emission control technologies required by this rule 
will not be ``reasonably available'' within 2 years of the promulgation 
of this rule. Moreover, the information provided to the Agency 
indicates that a 2-year deadline may force regulated sources to install 
equipment that is less reliable and that may cause safety concerns. 
Given the emphasis that Congress put on safety in these regulations and 
the fact that the Coast Guard will need to review such installations 
prior to operation, a 2-year deadline seems contrary to Congress' broad 
intent and may result in conflicts with Coast Guard requirements. The 
Agency has in the past provided sources with reasonable time to 
complete actions required by the Clean Air Act. See EPA rulemaking on 
fuel/fuel additives published on June 27, 1994 (59 FR 33042).
    Moreover, EPA believes that the imprecision of the term ``effective 
date'' could also provide EPA with the ability to allow compliance 
after 2 years. The distinction between ``effective dates'' of 
regulations and ``compliance dates'' is important and has been a clear 
part of administrative procedure for many years. See, e.g., section 
112(i)(3); Natural Resources Defense Council v. Environmental 
Protection Agency, 22 F. 3d 1125, 1138 (D.C. Cir. 1994).
    The Agency is requiring regulated RACT sources to provide proof 
that they have commenced construction of vapor collection systems and 
air pollution control devices within 2 years after promulgation of the 
final standards. The Agency believes that these actions can reasonably 
be achieved within 2 years of promulgation.
    The Agency believes that most RACT terminals will be able to meet 
the emissions reduction requirements contained in the final standards 
within the 3 years following the promulgation date. The Agency 
estimates that only 8 terminals subject to the RACT requirements are 
not presently controlling emissions to the level specified in the 
standards. These terminals are among the largest terminals in the U.S., 
and can reasonably be expected to have in-house staff capable of 
assisting in the design and installation of control technology. 
Furthermore, the Agency is aware that some of these terminals are 
already designing control equipment in anticipation of these final RACT 
requirements.
    The EPA shall allow existing sources regulated solely under section 
112 four years to be in full compliance with the emission control 
requirements promulgated under section 112. Sources must generally 
comply with MACT standards under section 112 within 3 years of 
promulgation. However, section 112(i) of the Act specifically allows 
EPA to provide sources with a waiver of up to 1 year to achieve full 
compliance with the requirements if they can show that the additional 
period is necessary for installing the controls. Commenters stated that 
standards containing similar compliance dates for a large number of 
sources would result in numerous facilities competing for a limited 
number of experienced contractors in order to meet the standards at the 
same time. Commenters suggested a staggered compliance schedule for the 
sources affected by the standards. Commenters also stated that many 
sources would require more than 3 years to install the required control 
equipment given the limited number of contractors experienced in 
installing control equipment in marine loading facilities and the lead 
time needed to meet permitting and safety requirements from permitting 
authorities and the U.S. Coast Guard.
    The Agency agrees with the commenters that many MACT sources would 
probably require 1-year waivers if there was a 3-year compliance date 
for MACT sources in the final rule. The Agency notes that these sources 
are typically smaller than the sources regulated under RACT, and would 
not be as likely to have in-house staff capable of assisting in the 
design and installation of control technology. Therefore, the Agency 
believes that the sources controlled under section 112 that are not 
controlled under section 183(f) should automatically receive a waiver 
of 1 year that will allow a total of four years from September 19, 1995 
to comply with the MACT emission reduction requirements. The Agency 
believes that this total of 4 years is sufficient time for the 
estimated 20 sources presently uncontrolled to design and install 
control technologies sufficient to meet the MACT standards. The Agency 
believes that the staggered compliance schedule (i.e., 3 years for RACT 
terminals and 4 years for MACT terminals) coupled with the reduced 
number of terminals required to control emissions under the final rule 
should alleviate commenters' concerns about the scarcity of qualified 
installation consultants and vendors. This extended 

[[Page 48393]]
schedule is also expected to address concerns regarding permitting 
delays.
    The Agency is providing the VMT with 30 months to be in full 
compliance with these regulations. The Agency believes, per its 
discussions with APSC, that this extension provides sufficient time to 
comply with the promulgated rule.
    (3) Addition of new subcategories under the section 112 regulations 
for offshore terminals and for the Alyeska Pipeline Service 
Corporation's Valdez Marine Terminal. In the proposed rule, the Agency 
established two subcategories based on size for the section 112 MACT 
regulations. The Agency also solicited comments on whether additional 
subcategories should be established under the MACT regulations for 
specific types of terminals based on particular characteristics of 
those types of terminals of which the Agency had no information at that 
time. Based on information received in the public comments, the Agency 
has determined that two additional subcategories exist within the 
marine tank vessel loading operation source category.
    (a) Subcategory for offshore terminals. As stated in the 
solicitation of comments in the proposed rule, the Agency does not 
believe that a facility at least one-half mile offshore is part of a 
land-based contiguous site. The Agency also stated that such offshore 
terminals present unique regulatory challenges such as costs, 
environmental impacts, and/or size constraints. The Agency requested 
information regarding the feasibility and costs of controlling 
emissions from offshore terminals. The Agency also requested comments 
on whether offshore terminals should be grouped into a separate 
subcategory and what the control status of terminals in such a 
subcategory should be. Comments in response to this request indicated 
that these types of vessel loading operations face significant 
challenges in controlling emissions that were different from land-
based, contiguous loading operations. These challenges include high 
costs, technical complications, and permitting requirements that would 
result from requirements to construct new platforms to locate control 
equipment adjacent to the offshore terminal or additional subsea or 
surface lines to route loading vapors to onshore control equipment. 
Commenters noted that these challenges are either non-existent or not 
as pronounced for onshore, contiguous terminals. The Agency has 
therefore determined that a subcategory for these types of terminals is 
justified and has based its definition for offshore terminals on a 
minimum distance of one-half mile from the terminal's furthest loading 
point to the shore, regardless of the existence of subsea lines. [See 
the discussion in section 2.3.2 of the TSD for the rationale supporting 
the one-half mile limit].
    Once the Agency determined that offshore terminals should be placed 
in a subcategory for the MACT standards, the MACT floor was determined 
(see Docket A-90-44, Item Number IV-B-2). Based on information received 
from commenters, (see Docket A-90-44, Item Number IV-D-136) the Agency 
estimates that there are fewer than 20 offshore terminals having subsea 
lines. None of these terminals presently control emissions from marine 
tank vessel loading. The Agency is also aware of additional offshore 
terminals that do not have subsea lines. Two of these terminals are 
known to presently control emissions (see Docket A-90-44, Item Number 
IV-D-80). Based on the information available to the Agency, the MACT 
floor for this subcategory is no control of HAP emissions (see MACT 
floor memorandum in Docket A-90-44, Item Number IV-B-2). Data submitted 
by commenters showed that the costs associated with the control of 
offshore terminals are between two and five times more expensive than 
comparable onshore control techniques (see Docket A-90-44, Item numbers 
IV-D-108 and IV-D-136). Because of the poor cost effectiveness 
resulting from these significantly higher costs, as well as the 
environmental, safety, and technical challenges associated with 
requiring control more efficient than the MACT floor, the Agency has 
selected the MACT floor level of no control for offshore marine tank 
vessel loading operations.
    The Agency also determined that offshore terminals loading 10 
million barrels or more per year of gasoline or 200 million barrels or 
more of crude oil should not be required to control VOC or HAP 
emissions under section 183(f) RACT requirements. Although one 
commenter (see Docket A-90-44, Item Number IV-D-80) noted two 
controlled offshore terminals, no information was submitted regarding 
the specific control techniques used at these two terminals. Since most 
of the other comments noted that the significantly higher costs and 
poor cost effectiveness shown by these sources (see previous paragraph) 
would make control requirements unreasonable for these offshore 
terminals, the Agency determined that requirement for controls at 
offshore RACT terminals would not be consistent with the requirements 
for the technology to be ``reasonable.''
    (b) Subcategory for Alyeska Pipeline Service Company's Valdez 
Marine Terminal. In the proposed rule, the Agency solicited comment on 
the possibility of placing the VMT in a separate subcategory. Comments 
from APSC and several other commenters representing State and local 
governments, industry, private citizens, and environmental groups were 
considered by the Agency in developing this final rule.
    The Agency has determined that the VMT should be placed in a 
separate subcategory for the following reasons: (1) The VMT is the 
largest (by a significant amount) crude oil loading operation in the 
U.S.; (2) special circumstances, including climatic and economic 
conditions, require keeping the oil moving through the pipeline; (3) 
severe meteorological conditions result in increased loading 
irregularity; (4) the VMT throughput projections show declining 
throughput over the next several years. Several comments from 
environmental groups, State and local agencies, and private citizens in 
the Valdez area did not object to placing VMT in a separate subcategory 
provided that emissions were controlled. Based on all of these factors, 
the Agency determined that APSC's VMT should be placed in a separate 
subcategory.
    Once the subcategory for VMT was established, the Agency determined 
the MACT floor for the subcategory (see Docket A-90-44, Item Number IV-
B-2). The VMT presently does not control emissions, therefore the MACT 
floor is no control. However, the Agency noted that in all of the 
comments received concerning the establishment of this subcategory, the 
cost effectiveness associated with requiring controls more stringent 
than the MACT floor is not prohibitive. The annual emissions reductions 
anticipated from controlling VMT are expected to be approximately 
19,000 Mg (20,900 tons) of VOC and approximately 2,500 Mg (2,750 tons) 
of HAP. The annual costs anticipated with today's regulation of VMT are 
expected to be $20 million. The resulting cost effectiveness is 
approximately $1,050 per megagram based on VOC or approximately $8,000 
per megagram based on HAP. The Agency therefore selected a strategy for 
both MACT and RACT standards for VMT that requires a reduction in 
emissions by 98 percent efficiency of all throughput loaded from at 
least two of the terminal's loading berths. Maximum limits for total 
throughput and throughput at uncontrolled berths (above which all VMT 
loading berths would be required to reduce emissions by 98 percent) are 
included as part of these standards. 

[[Page 48394]]
These throughput limits address the projected decreasing throughput 
that would necessitate the use of only two berths for routine loading 
after 2001. Provisions to allow for scheduled maintenance of the 
controlled berths are also established in the VMT standards.
    Some commenters initially noted that the cost of controlling VOC 
may be high relative to the benefits of controlling VOC at a remote 
site in an Arctic ozone attainment area. Additionally, some commenters 
initially stated that the benefits of controlling HAP would not appear 
to justify the costs. However, the Agency has also considered later 
comments from the APSC, the State of Alaska, the Prince William Sound 
Regional Citizens Advisory Committee (a local citizens group) and 
private citizens in determining MACT/RACT for the VMT. These commenters 
agreed that a Federal rule mandating control of primary emissions at 
the APSC was acceptable. After careful consideration of the costs, the 
environmental impacts and the comments, the Agency decided that MACT 
for this subcategory was control beyond the level of the MACT floor 
(see Docket A-44-90, Item Number IV-B-2).
    (4) Expansion of the petroleum refineries source category to 
include marine tank vessel loading operations collocated at petroleum 
refinery operations. The preamble to the proposed petroleum refinery 
NESHAP published in the Federal Register on July 15, 1994 (59 FR 36130) 
requested comments on whether marine tank vessel loading operations at 
refineries should be included in emissions averaging. On August 31, 
1994, the EPA also reopened the comment period for the proposed NESHAP 
for Marine Tank Vessel Loading Operations (59 FR 44955) to request 
comment on whether marine terminals collocated at refineries should be 
moved to the petroleum refinery source category. During the comment 
period for the gasoline distribution NESHAP, commenters requested that 
bulk gasoline terminals contiguous to a refinery be regulated by the 
petroleum refinery NESHAP.
    Several commenters responding to the marine tank vessel loading 
operations proposed NESHAP supported averaging of refinery process unit 
emissions with emissions from marine terminals and gasoline 
distribution operations that are located at refineries. The commenters 
cited more cost effective emission reduction as the advantage of 
including these emission points in emissions averaging and specifically 
commented that the costs per Mg emission reduction of the marine tank 
vessel loading emission controls are high. These commenters also 
claimed that emission calculation procedures for loading are well 
established and that adding marine loading to the averaging provisions 
will not appreciably increase the complexity of enforcement. Other 
commenters opposed including marine tank vessel loading and gasoline 
distribution in emissions averaging. Some commenters claimed that these 
are separate source categories, and the Act does not permit averaging 
across source categories. Others were concerned that including marine 
loading in averages could result in uncontrolled peak emissions.
    In the final rules, emissions from marine tank vessel loading 
operations, bulk gasoline terminal or pipeline breakout station storage 
vessels, and bulk gasoline terminal loading racks at petroleum 
refineries are allowed to be included in emissions averages. The 
petroleum refinery source category and source definitions have been 
changed to include marine tank vessel loading operations, bulk gasoline 
terminal and pipeline breakout station storage vessels, equipment 
leaks, and bulk gasoline terminal loading racks classified under SIC 
codes 5171 (Petroleum Bulk Stations and Terminals) and 4613 (Refined 
Petroleum Pipelines) that are located at refinery plant sites. Note 
that these operations are closely connected with refinery process unit 
operations since they transfer products of the refinery process units.
    A marine tank vessel loading operation or gasoline terminal or 
pipeline breakout station that is collocated at a petroleum refinery 
can be considered part of the same source as the refinery subject to 
this rule. Because these operations are redefined to be part of the 
source subject to the rule, the prohibition against intersource 
averaging is not violated. However, all terminals subject to section 
183(f) regardless of location will not be allowed to average emissions 
with petroleum refinery sources.
    In keeping with EPA's stated goal of increasing flexibility in 
rulemakings, this decision has been made to provide more opportunities 
to average. This decision optimizes the opportunities for refiners to 
find cost-effective emission reductions from overall facility 
operations on-site. Costs and cost effectiveness of controlling a 
particular kind of emission point, such as marine tank vessel loading, 
will vary depending on many site-specific factors. Emissions averaging 
allows the owner and operator to find the optimal control strategy for 
their particular situation.
    Including emissions from marine tank vessel loading operations, 
bulk gasoline terminal or pipeline breakout station storage vessels, 
and bulk gasoline terminal loading racks in emissions averages will 
result in equivalent or greater overall HAP emission reduction at each 
refinery. The averaging provisions are structured such that ``debits'' 
generated by not controlling an emission point that otherwise would 
require control must be balanced by achieving extra control at other 
refinery emission points covered by the NESHAP.
    With regard to commenter's concerns about peak emissions, the 
quarterly cap on the ratio of debits to credits is intended to limit 
the possibility of exposure peaks. Furthermore, because loading 
operations occur fairly frequently and emissions from an individual 
vessel filling or loading event are relatively small, such emissions 
are not expected to cause significant exposure peaks. Moreover, no 
evidence has been presented that emissions averaging would permit a 
very different mix of emissions to occur than would point-by-point 
compliance. That is, peaks of exposures from batch streams, storage, 
and loading operations should be equally likely under point-by-point 
compliance as under emissions averaging; therefore, emissions averaging 
does not represent a less effective control strategy. Furthermore, in 
order to receive approval for an emissions average, the owner or 
operator is required to demonstrate that the emissions average does not 
increase the risk or hazard relative to compliance without averaging.
    (5) Revision to the subcategories established based on annual HAP 
emissions from 1 ton per year to 10 tons per year of any single HAP or 
25 tons per year of total HAP. The proposed standards grouped major 
source terminals into two subcategories based on HAP emissions: 
Terminals with HAP emissions of 1 ton per year or more and terminals 
having HAP emissions of less than 1 ton per year. In the preamble of 
the proposed rule, the Agency requested comment on establishing these 
subcategories based on size (i.e., HAP emissions). In the public 
comments, the Agency found general, though not universal, agreement on 
establishing subcategories based on size for this source category. 
However, some of the comments encouraged the Agency to raise the HAP 
emissions level of the controlled subcategory. The final standards 
continue to group major source terminals into subcategories based on 
HAP emissions; however, these subcategories were changed to terminals 
with emissions of 10 tons per year or more of any single HAP or 25 

[[Page 48395]]
tons per year or more of total HAP and terminals having HAP emissions 
of less than 10 tons per year of all single HAP or less than 25 tons 
per year of total HAP. The Agency based this decision on information 
found in the comments received. Commenters noted that prior state 
regulations generally (though not invariably) distinguished between 
large tank vessel loading facilities that are responsible for the vast 
majority of emissions and small tank vessel loading facilities that are 
substantially less cost effective to regulate. (As discussed below, the 
incremental cost effectiveness of moving from the 10/25 ton per year 
distinction to the 1-ton delineation is between $80,000 and $112,000 
per megagram, while the cost effectiveness of the 10/25 ton delineation 
is between $14,500 and $24,000 per megagram.)
    Though section 112 does not provide any language indicating the 
criteria for subcategorization, section 112(d)(1) of the Act states 
that EPA may distinguish among classes, types, and sizes of sources in 
establishing standards. EPA believes that division of this source 
category into two subcategories based on size is appropriate in this 
instance. (See section 2.3.1 of the promulgation TSD for additional 
discussion of the subcategories based on size.)
    (6) Incorporation of minimum vapor pressure limit. The Agency 
received several comments regarding HAP having low vapor pressures. 
Most of these commenters stated that these low vapor pressure HAPs are 
not presently controlled under existing State regulations and that the 
control of these low vapor pressure compounds presents technical 
challenges and imposes significantly greater costs to the affected 
industry. The proposed rule enabled individual facilities to determine 
which products to control to achieve the 93 percent mass limit. 
Therefore, facilities would not have had to control low vapor pressure 
liquids under the proposed rule if higher vapor pressure liquids were 
available for control. Based on the comments received, the Agency 
altered the format of the MACT standards to explicitly exempt low vapor 
pressure liquids consistent with State requirements and recalculated 
the control requirement for liquids above the vapor pressure limit. 
Therefore, the MACT floor for existing sources is no control for 
liquids having a vapor pressure below 1.5 psia and 97 percent control 
for liquids having a vapor pressure 1.5 psia or greater. Because no low 
vapor pressure liquids are required to be controlled at any of the 
known existing sources, the MACT floor for new sources is also no 
control for liquids having a vapor pressure below 1.5 psia and 98 
percent control for liquids having a vapor pressure 1.5 psia or 
greater. The format of the standard was changed to an efficiency format 
to reflect the new approach.
    The issue of cost effectiveness to control emission streams from 
the loading of these low vapor pressure materials was also a realistic 
concern of the commenters. As the MACT floor for regulation of such 
activities is no control, EPA has discretion, based on section 112(d)'s 
criteria used for going beyond the floor, to institute a vapor pressure 
limit. Because of the high costs cited by commenters, the Agency 
elected not to require controls more stringent than the MACT floor for 
these low vapor pressure HAP. The Agency therefore selected a vapor 
pressure limit of 1.5 psia for determining the HAP emissions reduction 
for the final standards. Control of HAP having vapor pressures below 
this limit is not required to meet the standards.
    (7) Recalculation of the MACT floors. The MACT floors determined 
for this final rulemaking are different than those in the proposed 
rule. These final rule MACT floors reflect changes in the Agency's 
regulation of marine tank vessel loading including: (1) The 
establishment of subcategories for offshore terminals and the VMT 
terminal; (2) the incorporation of a 1.5 psia minimum vapor pressure 
limit instead of the weighted average as was proposed; and (3) the 
increase of the levels of the subcategories based on size (i.e., HAP 
emissions) from 1 ton per year to 10/25 tons per year. The MACT floors 
for the final rule also reflect comments on the proposed rule. However, 
the Agency has not changed the way in which the MACT floors for the 
final rule have been calculated. With the exception of the MACT floor 
for VMT, the MACT floors for existing and new sources in the marine 
tank vessel loading source category are shown in Table 1.
    Using the criteria established in section 112(d)(3) of the Act, and 
after inclusion of information supplied in the public comments, the 
MACT floors for existing source marine terminal subcategories subject 
to regulation under Title III of the Clean Air Act were determined. 
Additional information on the determination of these MACT floors is in 
the docket (Docket Number A-90-44, Item Number IV-A-2). There are 
approximately 44 major source terminals (not including the VMT) that 
emit 10 tons per year or more of any one hazardous air pollutant (HAP) 
or 25 tons per year or more of any combination of HAP. Twenty-three of 
these terminals are controlled. The resulting MACT floor level of 
control is a 97 percent reduction of HAP emissions. There are 
approximately 1,435 terminals that emit less than 10 tons per year of 
all individual HAP and less than 25 tons per year of combined HAP. 
Seventy-nine of these terminals reduce emissions from marine tank 
vessel loading. The resulting MACT floor level of control is no 
reduction in HAP emissions. The Agency estimated that there are less 
than 30 offshore terminals (i.e., loading terminals located 0.5 miles 
or more from shore). The Agency is aware of only 2 controlled offshore 
terminals. Therefore the resulting MACT floor level of control is no 
reduction in HAP emissions. The VMT is presently uncontrolled. Since 
this is the only terminal in the VMT source category, the MACT floor 
level of control is no control.
    The MACT floors for new source marine terminal subcategories 
subject to regulation under Title III of the Act were also calculated 
following the criteria in section 112(d)(3) of the Act. For new major 
source onshore terminals (not including the VMT) regardless of the 
marine tank vessel loading HAP emissions, the best performing source 
achieves a 98 percent reduction of controlled emissions. Therefore, the 
resulting MACT floor for these sources is 98 percent reduction of HAP 
emissions. For new major source offshore terminals whose marine tank 
vessel loading HAP emissions exceed the limits for a major source 
(i.e., 10 tons of any one HAP, or 25 tons of total HAP), the best 
controlled similar source achieves a 95 percent reduction of controlled 
emissions. The resulting MACT floor for new offshore major sources is 
therefore a 95 percent reduction in HAP emissions. Since the VMT 
subcategory only contains a single source, and it is not possible for 
an additional source to be added to this subcategory, no new source 
MACT floor was calculated for the VMT subcategory.
    (8) Incorporation of additional flexibility to the monitoring 
requirements and compliance provisions. The proposed rule required 
parametric monitoring or continuous emissions monitoring (CEM) as a 
means of showing compliance with the standards. Any exceedance of the 
parameters or concentration limits established during a performance 
test would have resulted in a violation of the standard. Comments 
indicated that this approach was too severe and warranted additional 
flexibility. Although the Agency continues to believe that parametric 
monitoring can be used to determine compliance given availability 

[[Page 48396]]
of sufficient test data to establish the relationship between control 
performance and associated parameters, in consideration of the lack of 
test data establishing the relationship between marine tank vessel 
loading emissions control efficiency and parametric monitoring and 
because of the batch nature of marine tank vessel loading operations, 
the Agency has thoroughly revised the monitoring requirements and 
compliance provisions of the final rule. A requirement for an operation 
and maintenance (O & M) plan has been added to the final regulation to 
ensure proper operation of the air pollution control and monitoring 
equipment. The O & M plan contains an inspection schedule for each 
component of the control and monitoring equipment. The ``compliance'' 
language that appeared in Sec. 63.563 of the proposed rule has been 
removed. In its place, the final rule contains provisions that require 
an unscheduled inspection and corrective actions when operating 
parameters exceed the applicable baseline parameters.
    Flexibility has also been added to the methods for determining 
baseline parameters. Owners or operators of a source required to reduce 
emissions may establish baseline parameters during a performance test 
or may choose to set the applicable baseline based on a manufacturer's 
recommended baseline operating parameter.
    Commenters on the proposed rule also requested that additional 
operating parameters be added to the regulation and that sources be 
allowed to apply for alternatives to the Administrator. Additional 
operating parameters have been added to the final regulation for 
several control devices. A cross reference to the general provisions 
found in 40 CFR part 63 (containing requirements for establishing 
alternative monitoring procedures) has been provided to assist sources 
seeking approval of alternative monitoring procedures. Commenters also 
requested that time intervals of the monitoring requirements be made 
consistent for each of the operating parameters. In the final rule, 
sources are required to monitor and record data points every 15 minutes 
for each operating parameter.

D. Minor Changes

    (1) Revisions to definitions and phrasing have been made to clarify 
the regulation.
    (2) Based on comments received and on changes to the monitoring and 
compliance provision requirements, the reporting requirements have been 
changed. Under today's final rule, the Agency is requiring the 
following one-time reports as specified in the general provisions found 
in 40 CFR part 63, subpart A: report of startup, construction or 
modification; notification and report of emissions tests and results 
and/or initial notification of compliance status; notification and 
report of physical/operational changes; notification and report of 
waiver applications; and an engineering report describing the vent 
system used to vent each vent stream to a control device.
    The final rule also requires owners or operators to submit yearly 
summary reports and yearly reports of excess emissions and monitoring 
system performance reports. However, in order to provide relief from 
the reporting requirements to well-controlled sources while assuring 
compliance with the standards, the Agency has provided that sources 
whose exceedances have durations that total less than 5 percent of the 
total reporting time for that reporting period and whose CMS downtime 
for the reporting period is less than 10 percent of the total operating 
time for that reporting period may submit only the summary report found 
in 40 CFR part 63 subpart A instead of both the summary report and the 
full excess emissions and continuous monitoring system performance 
report found in Sec. 63.567(d)(2).
    The final rule does not require quarterly reports of excess 
emissions or monitoring parameter exceedances. The Agency agreed with 
commenters that quarterly reporting did not add sufficient compliance 
assurance to warrant the high costs associated with the quarterly 
reporting. Quarterly reporting also did not agree with the revised 
monitoring and compliance determination requirements found in the final 
rule (see section 3(c)(5) of this preamble and section 2.6 of the 
promulgation TSD for additional discussion of the revised monitoring 
requirements contained in the final rule).
    (3) Several commenters requested clarification of the general 
provisions found in 40 CFR part 63 as they relate to this rule. A table 
identifying the relationship of the final General Provisions 
requirements has been added to the final regulation. Language similar 
to that in the General Provisions has been added to subpart Y in cases 
where a direct reference to the General Provisions was not appropriate.
    (4) References to the proposed Performance Specifications 101 and 
102 have been updated to incorporate the Agency's promulgation of 
Performance Specifications 8 and 9.

E. Other Significant Issues

(1) Regulation Under Sections 183(f) and 112
    The EPA proposed to regulate tank vessel loading operations under 
both sections 183(f) and 112 of the Act. Some commenters suggested that 
regulation under section 112 was inappropriate because section 183(f) 
specifically provides for regulation of tank vessel loading operations, 
whereas section 112 is a more general standard. On the other hand, one 
commenter believed that regulation was more appropriate, at least for 
certain facilities, under section 112.
    The Agency believes that the best interpretation of the Clean Air 
Act requires that standards be issued under both sections 183(f) and 
112. The language of section 112 of the Act is clear. ``[T]he 
Administrator shall publish * * * a list of all categories and 
subcategories of major sources and area sources of [HAP].'' Clean Air 
Act section 112(c)(1), 42 U.S.C. Sec. 7412(c)(1) [emphasis added]. 
Further, the Administrator ``shall promulgate regulations establishing 
emission standards for each category or subcategory of major sources 
and area sources of hazardous air pollutants listed for regulation 
pursuant to subsection (c).'' Clean Air Act section 112(d)(1), 42 
U.S.C. Sec. 7412(d)(1). The marine tank vessel loading operations 
source category is clearly a category of major sources, as defined in 
the Act. The Act is thus clear on its face that this source category 
should be regulated under section 112.
    The fact that two separate sections of the Act regulate the same 
source category does not necessitate that one of the sections should be 
ignored. In fact, unless the regulations promulgated under one section 
would create an inescapable conflict with regulations promulgated under 
the other section, both must be followed. The regulations promulgated 
under section 112 are not in conflict with those promulgated under 
section 183(f). EPA believes that any source regulated under both 
sections would have no problem meeting the requirements of both 
standards at the same time.
    Congress often provides for regulation of sources under two 
separate sections. The legislative history indicates that Congress was 
well aware that sources could be subject to dual regulation under 
section 112 and other sections of the Act. See page 167 of the Senate 
Committee Report (Report 101-228). In addition, where Congress wanted 
one section of the Clean Air Act to be exclusive of further regulation 
under 

[[Page 48397]]
section 112(d), they said so explicitly; see sections 129(h)(2), 
112(d)(9). Thus, Congress could have added specific language to section 
183(f) preventing the Agency from regulating this source category under 
section 112; however, it did not do so.
    In addition, neither the statute nor the legislative history 
indicates that Congress intended EPA regulations under section 183(f) 
to be the exclusive regulation of these sources. In fact, section 
183(f) explicitly provides that states may regulate tank vessel loading 
processes and, in fact, requires that any such regulations be as 
stringent or more stringent than the Agency's regulations under section 
183(f).

IV. Administrative Requirements

A. Docket

    The Docket is an organized and complete file of all the information 
considered by the EPA in the development of this rulemaking. The Docket 
is a dynamic file, since material is added throughout the rulemaking 
development. The docketing system allows members of the public and 
industries to readily identify and locate documents so that they can 
effectively participate in the rulemaking process. Along with the 
statement of basis and purpose of the proposed and promulgated 
standards and the EPA responses to significant comments, the contents 
of the Docket will serve as the record in case of judicial review 
[section 307(d)(7)(A)].

B. Paperwork Reduction Act

    The information collection requirements in this rule have been 
approved by the Office of Management and Budget (OMB) under the 
provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq., and 
have been assigned OMB control number (2060-0289). An Information 
Collection Request (ICR) document has been prepared by the EPA (ICR No. 
1679.02) to reflect the changed information requirements of the final 
rule.
    This collection of information has an estimated burden per affected 
facility of about 685 hours for the first year. In subsequent years, 
the burden is approximately 280 hours per affected facility. These 
burden estimates include time for reviewing instructions, searching 
existing data sources, gathering and maintaining the data needed, and 
completing and reviewing the collection of information.
    Send comments regarding the burden estimate or any other aspect of 
this collection of information, including suggestions for reducing this 
burden to Director, Regulatory Information Division, EPA, 401 M St., 
S.W. (Mail Code 2136), Washington, DC 20460, and to the Office of 
Information and Regulatory Affairs, Office of Management and Budget, 
Washington, DC 20503, marked ``Attention: Desk Officer for EPA.''

C. Administrative Designation and Regulatory Analysis

    Under Executive Order 12866 [58 FR 51735 (October 4, 1993)], the 
EPA is required to judge whether a regulation is ``significant'' and 
therefore subject to Office of Management and Budget (OMB) review and 
the requirements of this Executive Order to prepare a regulatory impact 
analysis (RIA). The Order defines ``significant regulatory action'' as 
one that is likely to result in a rule that may: (1) Have an annual 
effect on the economy of $100 million or more or adversely affect in a 
material way the economy, a sector of the economy, productivity, 
competition, jobs, the environment, public health or safety, or State, 
local, or tribal governments or communities; (2) create a serious 
inconsistency or otherwise interfere with an action taken or planned by 
another agency; (3) materially alter the budgetary impact of 
entitlements, grants, user fees, or loan programs, or the rights and 
obligations of recipients thereof; or (4) raise novel legal or policy 
issues arising from legal mandates, the President's priorities, or the 
principles set forth in the Executive Order.
    Pursuant to the terms of Executive Order 12866, it has been 
determined that this rule is a ``significant regulatory action'' 
because it will have an annual effect on the economy of $100 million or 
more. As such, this action was submitted to OMB for review. Changes 
made in response to OMB suggestions or recommendations are documented 
in the public record (see Docket A-90-44, Item Number IV-H-2).

D. Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires the 
EPA to consider potential impacts of proposed regulations on small 
business ``entities,'' which are small businesses, small organizations, 
and small governments. It is EPA's current policy to perform a 
regulatory flexibility analysis whenever a regulation is anticipated to 
adversely affect any small entities. An economic impact and regulatory 
flexibility analysis for this regulation was performed and included 
within the regulatory impact analysis that has been submitted to the 
public docket (Docket Number A-90-44, Item Number IV-A-2).
    The regulatory flexibility analysis identified two types of 
businesses that could incur adverse economic impacts from this 
standard, marine terminal operations and marine vessel operations. With 
regard to marine terminal operations, only the very largest terminal 
operations are expected to be affected by this standard. The decision 
not to require controls at existing smaller operations greatly reduces 
the potential for adverse economic impacts on small terminal 
operations. Nevertheless, some of the smaller terminal operations that 
will be affected by this regulation could be put under increased 
competitive pressure as a result of this rule. Of these terminals, 
however, it is expected that few or none are independently owned. The 
rest are part of large integrated petroleum operations. The number of 
small business terminal operations affected by this regulation is 
expected to be minimal.
    With regard to marine vessel operations, the economic impact 
analysis considered the majority of these operations to be small 
businesses. However, the number of vessel operations significantly 
impacted from the proposed standard is not expected to be substantial. 
Only a relatively small percentage of U.S. marine transported 
throughput will be impacted by the standard. Excluding crude oil volume 
shipped by large tankers from the VMT, no more than one-third of the 
remaining U.S. marine transported throughput is expected be impacted by 
the standard. It is expected that an even smaller percentage of U.S. 
vessels will need to be retrofitted to accommodate the volume of 
affected products. Only the largest and newest vessels (i.e., those 
that will cost least to retrofit) will therefore need to be 
retrofitted. Moreover, it is expected that vessel owners will be able 
to pass forward most retrofit costs in the form of higher prices. 
Vessels that cannot retrofit cost effectively and that cannot pass 
through costs can be dedicated to transporting unregulated products.
Economic Impacts
    The EPA performed an economic impact analysis of the regulatory 
requirements in this regulation. Potential price, output, and 
employment impacts for affected products and for the marine transport 
industry were examined. Detailed results from the analysis are included 
in the regulatory impact analysis for this rule that has been submitted 
to the public docket. 

[[Page 48398]]

    Estimated maximum price increases for the affected products varied 
but were not large (less than 1%). These price-increase estimates 
reflect the control cost increases for transporting crude and products. 
Because these increases are small and because the elasticities of 
demand for petroleum products are small, estimated percent output 
reductions were minimal. Correspondingly, estimated employment 
reductions were also relatively small.
    Potentially significant economic impacts on some of the smaller 
affected terminal operations were identified, although the decision not 
to require emission controls for existing smaller operations greatly 
reduces the potential for adverse impacts on small terminal operations. 
These potential impacts would result from the high per barrel control 
cost differential between the smaller and larger terminal operations 
that would need to control emissions. Some of these smaller terminal 
operations, to the extent that they are competing with nearby larger or 
unaffected terminal operations, could have had difficulty raising 
prices sufficiently to cover cost increases and could have been 
significantly and adversely impacted by this rule if the rule were 
applicable to such operations.
    The potential economic impact on marine vessel owners was 
substantially reduced because of the decision not to require emission 
controls for small terminals in this rulemaking. Because only a 
relatively small percentage of U.S. marine transported volume of 
products will be impacted by the standard, only a relatively small 
percentage of U.S. marine vessels will need to retrofit. Thus only the 
vessels that will cost least to retrofit (most likely the larger, 
newer, double-skin vessels) will do so, leading to some degree of 
dedicated service. Vessel owners that do retrofit probably will be able 
to pass most retrofit costs forward in terms of higher prices.

E. Unfunded Mandates Act

    Under section 202 of the Unfunded Mandates Reform Act of 1995 
(Unfunded Mandates Act), signed into law on March 22, 1995, the EPA 
must prepare a budgetary impact statement to accompany any proposed or 
final rule that includes a Federal mandate that may result in estimated 
costs to State, local, or tribal governments in the aggregate; or to 
the private sector of $100 million or more. The budgetary impact 
statement must include: (1) An identification of the Federal law under 
which the rule is promulgated; (2) a qualitative and quantitative 
assessment of anticipated costs and benefits of the Federal mandate and 
an analysis of the extent to which such costs to State, local, and 
tribal governments may be paid with Federal financial assistance; (3) 
if feasible, estimates of the future compliance costs and any 
disproportionate budgetary effects of the mandate; (4) if feasible, 
estimates of the effect on the national economy; and (5) a description 
of the Agency's prior consultation with elected representatives of 
State, local, and tribal governments and a summary and evaluation of 
the comments and concerns presented. Section 203 provides that if any 
small governments may be significantly or uniquely impacted by the 
rule, the Agency must establish a plan for obtaining input from and 
informing, educating, and advising any such potentially affected small 
governments.
    Under section 205 of the Unfunded Mandates Act, the Agency must 
identify and consider a reasonable number of regulatory alternatives 
before promulgating a rule for which a budgetary impact statement must 
be prepared. The Agency must select from those alternatives the least 
costly, most cost-effective, or least burdensome alternative for State, 
local, and tribal governments and the private sector, that achieves the 
objectives of the rule, unless the Agency explains why this alternative 
is not selected or unless the selection of this alternative is 
inconsistent with law.
    Because this final rule is estimated to result in the expenditure 
by State, local, and tribal governments in aggregate or by the private 
sector of $60 million to $100 million per year starting in 2000, EPA 
has prepared a supplement to the Regulatory Impact Analysis (RIA) in 
compliance with the Unfunded Mandates Act. The EPA summarizes that 
supplement as follows:
    This final rule is promulgated under section 112 and section 183(f) 
of the Clean Air Act. The analysis in the RIA developed in preparation 
of the proposed rule and revised in preparation of the final rule 
contains the information to be considered in response to the 
requirements of the Unfunded Mandates Act.
    Total expenditures resulting from the final rule are estimated at 
between $60 million and $100 million (of which less than $75,000 is by 
State, local, and tribal governments) per year in 1997-2000; and 
$550,000 (of which $38,000 is by State, local, and tribal governments) 
per year starting in 2001. There are no federal funds available to 
assist State, local, and tribal governments in meeting these costs. 
There are important benefits from VOC and HAP emission reductions 
because these compounds have significant, adverse impacts on human 
health and welfare and on the environment. The rule does not have any 
disproportionate budgetary effects on any particular region of the 
nation, any State, local, or tribal government, or urban or rural or 
other type of community. On the contrary, the rule will result in only 
a minimal increase in the average product rates (less than 1 percent). 
Moreover, the rule will not have a material effect on the national 
economy.
    Prior to issuing this rule, the EPA provided numerous opportunities 
(e.g., National Air Pollution Control Techniques Advisory Committee 
proceedings; public comment period; public hearing; meetings with 
industry, trade associations, state and local air pollution 
representatives; State, local, and tribal governments; and concerned 
citizens) for consultation with interested parties. In general, State 
and local environmental agencies advocated that EPA adopt more 
stringent environmental controls. The Agency evaluated the comments and 
concerns expressed, and the final rule reflects, to the extent 
consistent with sections 112 and 183(f) of the Act, those comments and 
concerns. While small governments are not significantly or uniquely 
affected by the rule, these procedures, as well as additional public 
conferences and meetings, gave small governments an opportunity to give 
meaningful and timely input and obtain information, education, and 
advice on compliance.
    The Agency considered several regulatory options in developing the 
rule. As discussed above, the Agency has found that regulation solely 
under section 183(f) of the Act would not be consistent with the law. 
The options selected in the final rule for all subcategories of sources 
except the VMT subcategory are the least costly and least burdensome 
alternatives currently available for achieving the objectives of 
sections 112 and 183(f) of the Act. Regarding regulation of the VMT, 
the Agency notes that the cost effectiveness of controlling VOC at this 
terminal is approximately $1,050 per Mg and the cost effectiveness of 
controlling HAP is approximately $8,000 per Mg. The Agency initially 
received comments stating that the cost of controlling VOC at this 
terminal is high relative to the benefits of controlling VOC at a 
remote site in an Arctic ozone attainment area. Additionally, some 
commenters initially stated that the benefits of controlling HAP would 
not appear to justify the costs. However, the Agency has also 
considered later comments from the 

[[Page 48399]]
APSC, the State of Alaska, the Prince William Sound Regional Citizens 
Advisory Committee (a local citizens group) and private citizens in 
determining MACT/RACT for the VMT. These commenters agreed that a 
Federal rule mandating control of the primary emissions at the APSC was 
acceptable. After careful consideration of the costs, the environmental 
impacts and the comments, the Agency decided that MACT for this 
subcategory was control beyond the level of the MACT floor (see Docket 
A-44-90, Item Number IV-B-2).

balancing. This does not include the vapor collection system that is 
part of any marine vessel vapor collection manifold system.
    Vapor-tight marine vessel means a marine tank vessel that has 
demonstrated within the preceding 12 months to have no leaks. A marine 
tank vessel loaded at less than atmospheric pressure is assumed to be 
vapor tight for the purpose of this standard.
    Volatile organic compounds or VOC is as defined in 40 CFR 51.100(s) 
of this chapter.

paragraph (d)(2)(iii) with a vapor collection system and air pollution 
control device and shall load marine tank vessels over loading berths 
equipped with a vapor collection system and control device to the 
maximum extent practicable. The owner or operator shall equip all 
loading berths that will be used for routine loading after March 19, 
1998 with a vapor collection system and control device if the annual 
average daily loading rate for all loading berths exceeds the limits in 
paragraphs (d)(2)(i)(A), (B), and (C) of this section.
    (A) For 1995, 1,630,000 barrels per day; and
    (B) For 1996, 1,546,000 barrels per day; and
    (C) For 1997, 1,445,000 barrels per day.
    (ii) Maximum extent practicable means that the total annual average 
daily loading over all loading berths not equipped with a vapor 
collection system and control device shall not exceed the totals in 
paragraphs (d)(2)(ii)(A) and (B):
    (A) Loading allowances for marine tank vessel loading operations at 
loading berths not equipped with control devices. The following maximum 
annual average daily loading rate for routine loading at loading berths 
not equipped with control devices in any of the following years shall 
not exceed:
    (a) For 1998, 275,000 barrels per day;
    (b) For 1999, 205,000 barrels per day;
    (c) For 2000, 118,000 barrels per day;
    (d) For 2001, 39,000 barrels per day; and
    (e) For 2002 and subsequent years, no marine tank vessel loading 
operations shall be performed at berths not equipped with a vapor 
collection system and control device, except as allowed for maintenance 
under paragraph (B).
    (B) Maintenance allowances for loading berths subject under 
paragraph (d)(2)(i). Beginning in the year 2000, the owner or operator 
of the VMT source may have a maximum of 40 calendar days per calendar 
year use of loading berths not equipped with a vapor collection system 
and control device, in accordance with the limits in paragraph 
(d)(2)(ii)(B)(a), (b), or (c), to allow for maintenance of loading 
berths subject to paragraph (d)(2)(i). Beginning in the year 2002, the 
total annual average daily loading of crude oil over all loading berths 
not equipped with a vapor collection system and control device shall 
not exceed the amount stated in paragraph (d)(2)(ii)(B)(b). The 40 days 
allowed for maintenance shall be converted into a compliance measure of 
annual average daily loading over the loading berths not equipped with 
a vapor collection system and control device as follows:
    (a) If the total annual average daily volume of crude oil loaded at 
the facility was greater than or equal to 1,100,000 barrels per day in 
the prior calendar year, the maintenance allowance shall not exceed an 
annual average daily loading of 60,000 barrels per day.
    (b) If the total annual average daily volume of crude oil loaded at 
the facility was less than 1,100,000 barrels per day and greater than 
or equal to 550,000 barrels per day in the prior calendar year, the 
maintenance allowance for the calendar year shall not exceed Qm:
[GRAPHIC][TIFF OMITTED]TR19SE95.000

Where:

Qm = maintenance allowance, barrels per day
P = prior calendar year's average daily volume of crude oil loaded at 
the facility, barrels per day.

    (c) If the total annual average daily volume of crude oil loaded at 
the facility was less than 550,000 barrels per day in the prior 
calendar year, there shall be no maintenance allowance.
    (iii) If the average daily loading rate for the loading berths not 
equipped with a vapor collection system and control device is greater 
than the combined 

[[Page 48407]]
amounts in any year listed in paragraphs (d)(2)(i)(A), (B), and (C) and 
(d)(2)(ii)(A) and (B), then the owner or operator of the VMT source 
shall equip all loading berths used for routine loading with a vapor 
collection system and control device within 2 years of the exceedance 
except that in an emergency situation the Administrator may, instead of 
requiring controls, approve an alternative plan to reduce loading over 
the unequipped berth(s) to a level which will ensure compliance with 
the applicable limit. Beginning in the year 2002, the owner or operator 
of the VMT source shall equip all uncontrolled loading berths used for 
marine tank vessel loading operations beyond the maintenance allowance 
in paragraph (d)(2)(ii)(B) with a vapor collection system and control 
device.
    (iv) The owner or operator of the VMT source shall develop a 
program to communicate to relevant facility operations and marine 
transportation personnel and engage their active and consistent 
participation in honoring the intent and goal of minimizing loaded 
volumes over the unequipped berths and maximizing the loaded volumes at 
the berths equipped with a vapor collection system and control device 
to prevent exceedance of the load volume limits in paragraphs 
(d)(2)(ii)(A) and (B). This program is to be presented semi-annually 
during the first year of compliance and annually thereafter until the 
use of unequipped berths for routine loading is no longer required.
    (3) The owner or operator of the VMT source shall submit annual 
reports on or before January 31 of each year to the Administrator 
certifying the annual average daily loading rate for the previous 
calendar year. Beginning on January 31, 1996, for the reported year 
1995, the annual report shall specify the annual average daily loading 
rate over all loading berths. Beginning on January 31, 1999, for the 
reported year 1998, the annual report shall specify the annual average 
daily loading rate over all loading berths, over each loading berth 
equipped with a vapor collection system and control device, and over 
each loading berth not equipped with a vapor collection system and 
control device. The annual average daily loading rate under this 
section is calculated as the total amount of crude oil loaded during 
the calendar year divided by 365 days or 366 days, as appropriate.
    (e) Operation and maintenance requirements for air pollution 
control equipment and monitoring equipment for affected sources. At all 
times, including periods of startup, shutdown, and malfunction, owners 
or operators of affected sources shall operate and maintain a source, 
including associated air pollution control equipment, in a manner 
consistent with safety and good air pollution control practices for 
minimizing emissions. Determination of whether acceptable operation and 
maintenance procedures are being used will be based on information 
available to the Administrator which may include, but is not limited 
to, monitoring results, review of operation and maintenance procedures, 
review of operation and maintenance records, and inspection of the 
source.
    (1) The Administrator will determine compliance with design, 
equipment, work practice, or operational emission standards by 
evaluating an owner or operator's conformance with operation and 
maintenance requirements.
    (2) The owner or operator of an affected source shall develop and 
implement a written operation and maintenance plan that describes in 
detail a program of corrective action for varying (i.e., exceeding 
baseline parameters) air pollution control equipment and monitoring 
equipment, based on monitoring requirements in Sec. 63.564, used to 
comply with these emissions standards. The plan shall also identify all 
routine or otherwise predictable continuous monitoring system 
(thermocouples, pressure transducers, continuous emissions monitors 
(CEMS), etc.) variances.
    (i) The plan shall specify procedures (preventive maintenance) to 
be followed to ensure that pollution control equipment and monitoring 
equipment functions properly and variances of the control equipment and 
monitoring equipment are minimal.
    (ii) The plan shall identify all operating parameters to be 
monitored and recorded for the air pollution control device as 
indicators of proper operation and shall establish the frequency at 
which the parameters will be monitored (see Sec. 63.564).
    (iii) Owners or operators of affected sources shall incorporate a 
standardized inspection schedule for each component of the control 
device used to comply with the emissions standards in Sec. 63.562(b), 
(c), and (d). To satisfy the requirements of this paragraph, the owner 
or operator may use the inspection schedule recommended by the vendor 
of the control system or any other technical publication regarding the 
operation of the control system.
    (iv) Owners or operators shall develop and implement a continuous 
monitoring system (CMS) quality control program. The owner or operator 
shall develop and submit to the Administrator for approval upon request 
a site-specific performance evaluation test plan for the CMS 
performance evaluation required in Sec. 63.8(e) of subpart A of this 
part. Each quality control program shall include, at a minimum, a 
written protocol that describes procedures for initial and any 
subsequent calibration of the CMS; determination and adjustment of the 
calibration drift of the CMS; preventive maintenance of the CMS, 
including spare parts inventory; data recording, calculations, and 
reporting; and accuracy audit procedures, including sampling and 
analysis methods. The owner or operation shall maintain records of the 
procedures that are part of the quality control program developed and 
implemented for CMS.
    (3) Based on the results of the determination made under paragraph 
(e)(2), the Administrator may require that an owner or operator of an 
affected source make changes to the operation and maintenance plan for 
that source. Revisions may be required if the plan:
    (i) Does not address a variance of the air pollution control 
equipment or monitoring equipment that has occurred that increases 
emissions;
    (ii) Fails to provide for operation during a variance of the air 
pollution control equipment or the monitoring equipment in a manner 
consistent with safety and good air pollution control practices; or
    (iii) Does not provide adequate procedures for correcting a 
variance of the air pollution control equipment or monitoring equipment 
as soon as reasonable.
    (4) If the operation and maintenance plan fails to address or 
inadequately addresses a variance event at the time the plan was 
initially developed, the owner or operator shall revise the operation 
and maintenance plan within 45 working days after such an event occurs. 
The revised plan shall include procedures for operating and maintaining 
the air pollution control equipment or monitoring equipment during 
similar variance events and a program for corrective action for such 
events.
    (5) The operation and maintenance plan shall be developed by the 
source's compliance date. The owner or operator shall keep the written 
operation and maintenance plan on record to be made available for 
inspection, upon request, by the Administrator for the life of the 
source. In addition, if the operation and maintenance plan is revised, 
the owner or operator shall keep previous (i.e., superseded) versions 
of the plan on record to be made available for inspection upon request 
by the Administrator for a period of 5 years after each revision to the 
plan. 

[[Page 48408]]

    (6) To satisfy the requirements of the operation and maintenance 
plan, the owner or operator may use the source's standard operating 
procedures (SOP) manual, an Occupational Safety and Health 
Administration (OSHA) plan, or other existing plans provided the 
alternative plans meet the requirements of this section and are made 
available for inspection when requested by the Administrator.


Sec. 63.563  Compliance and performance testing.

    (a) The following procedures shall be used to determine compliance 
with the emissions limits under Sec. 63.562(b)(1), (c)(2), and (d)(1):
    (1) Vent stream by-pass requirements for the terminal's vapor 
collection system.
    (i) In accordance with Sec. 63.562(b)(1)(i), (c)(2)(i), and 
(d)(1)(i), each valve in the terminal's vapor collection system that 
would route displaced vapors to the atmosphere, either directly or 
indirectly, shall be secured closed during marine tank vessel loading 
operations either by using a car-seal or a lock-and-key type 
configuration, or the by-pass line from the valve shall be equipped 
with a flow indicator, except for those valves used for pressure/vacuum 
relief, analyzers, instrumentation devices, sampling, and venting for 
maintenance. Marine tank vessel loading operations shall not be 
performed with open by-pass lines.
    (ii) Repairs shall be made to valves, car-seals, or closure 
mechanisms no later than 15 days after a change in the position of the 
valve or a break in the car-seal or closure mechanism is detected or no 
later than prior to the next marine tank vessel loading operation, 
whichever is later.
    (2) Ship-to-shore compatibility of vapor collection systems. 
Following the date on which the initial performance test is completed, 
marine tank vessel loading operations must be performed only if the 
marine tank vessel's vapor collection equipment is compatible to the 
terminal's vapor collection system; marine tank vessel loading 
operations must be performed only when the marine tank vessel's vapor 
collection equipment is connected to the terminal's vapor collection 
system, as required in Sec. 63.562(b)(1)(ii), (c)(2)(ii), and 
(d)(1)(ii).
    (3) Pressure/vacuum settings for the marine tank vessel's vapor 
collection equipment. During the initial performance test required in 
paragraph (b)(1) of this section, the owner or operator of an affected 
source shall demonstrate compliance with operating pressure 
requirements of 33 CFR 154.814 using the procedures in Sec. 63.565(b).
    (4) Vapor-tightness requirements of the marine vessel. The owner or 
operator of an affected source shall use the procedures in paragraph 
(a)(4)(i), (ii), (iii), or (iv) of this section to ensure that marine 
tank vessels are vapor tight, as required in Sec. 63.562(b)(1)(iii), 
(c)(2)(iii), and (d)(1)(iii).
    (i) Pressure test documentation for determining vapor tightness of 
the marine vessel. The owner or operator of a marine tank vessel, who 
loads commodities containing HAP not determined to be exempt under 
Sec. 63.560(d) at an affected source, shall provide a copy of the 
vapor-tightness pressure test documentation described in Sec. 63.567(i) 
for each marine tank vessel prior to loading. The date of the test 
listed in the documentation must be within the preceding 12 months, and 
the test must be conducted in accordance with the procedures in 
Sec. 63.565(c)(1). Following the date on which the initial performance 
test is completed, the affected source must check vapor-tightness 
pressure test documentation for marine tank vessels loaded at positive 
pressure.
    (ii) Leak test documentation for determining vapor tightness of the 
marine vessel. If no documentation of the vapor tightness pressure test 
as described in paragraph (a)(4)(i) of this section is available, the 
owner or operator of a marine tank vessel, who loads commodities 
containing HAP not determined to be exempt under Sec. 63.560(d) at an 
affected source, shall provide the leak test documentation described in 
Sec. 63.567(i) for each marine tank vessel prior to loading. The date 
of the test listed in the documentation must be within the preceding 12 
months, and the test must be conducted in accordance with the 
procedures in Sec. 63.565(c)(2). If the marine tank vessel has failed 
its most recent vapor-tightness leak test at that terminal, the owner 
or operator of the non-vapor-tight marine tank vessel shall provide 
documentation that the leaks detected during the previous vapor-
tightness test have been repaired and documented with a successful 
vapor-tightness leak test described in Sec. 63.565(c)(2) conducted 
during loading. If the owner or operator of the marine tank vessel can 
document that repair is technically infeasible without cleaning and gas 
freeing or dry-docking the vessel, the owner or operator of the 
affected source may load the marine tank vessel. Following the date on 
which the initial performance test is completed, an affected source 
must check the vapor-tightness leak test documentation for marine tank 
vessels loaded at positive pressure.
    (iii) Leak test performed during loading using Method 21 for 
determining vapor tightness of the marine vessel. If no documentation 
of vapor tightness as described in paragraphs (a)(4)(i) or (ii) of this 
section is available, the owner or operator of a marine tank vessel, 
who loads commodities containing HAP not determined to be exempt under 
Sec. 63.560(d) at an affected source, shall perform a leak test of the 
marine tank vessel during marine tank vessel loading operation using 
the procedures described in Sec. 63.565(c)(2).
    (A) If no leak is detected, the owner or operator of a marine tank 
vessel shall complete the documentation described in Sec. 63.567(i) 
prior to departure of the vessel.
    (B) If a leak is detected, the owner or operator of the marine tank 
vessel shall document the vapor-tightness failure for the marine tank 
vessel prior to departure of the vessel. The leaking component shall be 
repaired prior to the next marine tank vessel loading operation at a 
controlled terminal unless the repair is technically infeasible without 
cleaning and gas freeing or dry-docking the vessel. If the owner or 
operator of the vessel provides documentation that repair of such 
equipment is technically infeasible without cleaning and gas freeing or 
dry-docking the vessel, the equipment responsible for the leak will be 
excluded from future Method 21 tests until repairs are effected. A copy 
of this documentation shall be maintained by the owner or operator of 
the affected source. Repair of the equipment responsible for the leak 
shall occur the next time the vessel is cleaned and gas freed or dry-
docked. For repairs that are technically feasible without dry-docking 
the vessel, the owner or operator of the affected source shall not load 
the vessel again unless the marine tank vessel owner or operator can 
document that the equipment responsible for the leak has been repaired.
    (iv) Negative pressure loading. The owner or operator of an 
affected source shall ensure that a marine tank vessel is loaded with 
the product tank below atmospheric pressure (i.e., at negative gauge 
pressure). The pressure shall be measured between the facility's vapor 
connection and its manual isolation valve, and the measured pressure 
must be below atmospheric pressure. Following the date on which the 
initial performance test is completed, marine tank vessel loading 
operations for nonvapor-tight vessels must be performed below 
atmospheric pressure 

[[Page 48409]]
(i.e., at negative gauge pressure) in the product tank.
    (b) Compliance determination for affected sources. The following 
procedures shall be used to determine compliance with the emissions 
limits under Sec. 63.562(b), (c), and (d).
    (1) Initial performance test. An initial performance test shall be 
conducted using the procedures listed in Sec. 63.7 of subpart A of this 
part according to the applicability in Table 1 of Sec. 63.560, the 
procedures listed in this section, and the test methods listed in 
Sec. 63.565. The initial performance test shall be conducted within 180 
days after the compliance date for the specific affected source. During 
this performance test, sources subject to MACT standards under 
Sec. 63.562(b)(2), (3), (4), and (5) and (d)(2) shall determine the 
reduction of HAP emissions, as VOC, for all combustion or recovery 
devices other than flares. Sources subject to RACT standards under 
Sec. 63.562(c)(3), (4), and (5) and (d)(2) shall determine the 
reduction of VOC emissions for all combustion or recovery devices other 
than flares.

requirements in Sec. 63.7 of subpart A of this part in accordance with 
the provisions for applicability of subpart A to this subpart in Table 
1 of Sec. 63.560 and the performance testing requirements in this 
section.
    (b) Pressure/vacuum settings of marine tank vessel's vapor 
collection equipment. For the purpose of determining compliance with 
Sec. 63.563(a)(3), the following procedures shall be used:
    (1) Calibrate and install a pressure measurement device (liquid 
manometer, magnehelic gauge, or equivalent instrument) capable of 
measuring up to the maximum relief set pressure of the pressure-vacuum 
vents;
    (2) Connect the pressure measurement device to a pressure tap in 
the terminal's vapor collection system, located as close as possible to 
the connection with the marine tank vessel; and
    (3) During the performance test required in Sec. 63.563(b)(1), 
record the pressure every 5 minutes while a marine tank vessel is being 
loaded and record the highest instantaneous pressure and vacuum that 
occurs during each loading cycle.
    (c) Vapor-tightness test procedures for the marine tank vessel.

recordkeeping and monitoring requirements specified in this subpart and 
subpart A of this part.
    (3) The frequency of reporting of excess emissions and continuous 
monitoring system performance and summary reports required may be 
reduced only after the owner or operator notifies the Administrator in 
writing of his or her intention to make such a change and the 
Administrator does not object to the intended change. In deciding 
whether to approve a reduced frequency of reporting, the Administrator 
may review information concerning the source's entire previous 
performance history during the 5-year recordkeeping prior to the 
intended change, including performance test results, monitoring data, 
and evaluations of an owner or operator's conformance with operation 
maintenance requirements. Such information may be used by the 
Administrator to make a judgement about the source's potential for 
noncompliance in the future. If the Administrator will notify the owner 
or operator in writing within 45 days after receiving notice of the 
owner or operator's intention. The notification from the Administrator 
to the owner or operator will specify the grounds on which the 
disapproval is based. In the absence of a notice of disapproval within 
45 days, approval is automatically granted.

accuracy testing of temperature, pressure, or flow monitoring devices. 
The written report shall also include the name, title, and signature of 
the responsible official who is certifying the accuracy of the report. 
When no excess emissions or exceedances have occurred or monitoring 
equipment has not been inoperative, repaired, or adjusted, such 
information shall be stated in the report. This information will be 
kept for a minimum of 5 years and made readily available to the 
Administrator or delegated State authority upon request.
    (5) If the total duration of excess emissions or control system 
parameter exceedances for the reporting period is less than 5 percent 
of the total operating time for the reporting period, and CMS downtime 
for the reporting period is less than 10 percent of the total operating 
time for the reporting period, only the summary report of 
Sec. 63.10(e)(3)(vi) of subpart A of this part shall be submitted, and 
the full excess emissions and continuous monitoring system performance 
report of paragraph (e)(4) of this section need not be submitted unless 
required by the Administrator.
    (6) If the total duration of excess emissions or process or control 
system parameter exceedances for the reporting period is 5 percent or 
greater of the total operating time for the reporting period, or the 
total CMS downtime for the reporting period is 10 percent or greater of 
the total operating time for the reporting period, both the summary 
report of Sec. 63.10(e)(3)(vi) of subpart A of this part and the excess

all valves and vent pipes that could vent the stream to the atmosphere, 
thereby bypassing the control device, and identify which valves are 
car-sealed opened and which valves are car-sealed closed.
    (g) If a vent system, or vapor collection system, containing valves 
that could divert the emission stream away from the control device is 
used, each owner or operator of an affected source shall keep for at 
least 5 years up-to-date, readily accessible continuous records of:
    (1) All periods when flow bypassing the control device is indicated 
if flow indicators are installed under Sec. 63.563(a)(1) and 
Sec. 63.564(b), and
    (2) All times when maintenance is performed on car-sealed valves, 
when the car-seal is broken, and when the valve position is changed 
(i.e., from open to closed for valves in the vent piping to the control 
device and from closed to open for valves that vent the stream directly 
or indirectly to the atmosphere bypassing the control device) if valves 
are monitored under Sec. 63.564(b).
    (h) The owner or operator of an affected source shall keep the 
vapor-tightness documentation required under Sec. 63.563(a)(4) on file 
at the source in a permanent form available for inspection.
    (i) Vapor tightness test documentation for marine tank vessels. The 
owner or operator of an affected source shall maintain a documentation 
file for each marine tank vessel loaded at that source to reflect 
current test results as determined by the appropriate method in 
Sec. 63.565(c)(1) and (2). Updates to this documentation file shall be 
made at least once per year. The owner or operator shall include, as a 
minimum, the following information in this documentation:
    (1) Test title;
    (2) Marine vessel owner and address;
    (3) Marine vessel identification number;
    (4) Loading time, according to Sec. 63.563(a)(4)(ii) or (iii), if 
appropriate;
    (5) Testing location;
    (6) Date of test;
    (7) Tester name and signature;
    (8) Test results from Sec. 63.565(c)(1) or (2), as appropriate;
    (9) Documentation provided under Sec. 63.563(a)(4)(ii) and (iii)(B) 
showing that the repair of leaking components attributed to a failure 
of a vapor-tightness test is technically infeasible without dry-docking 
the vessel; and
    (10) Documentation that a marine tank vessel failing a pressure 
test or leak test has been repaired.
    (j) Emission estimation reporting and recordkeeping procedures. The 
owner or operator of each source complying with the emission limits 
specified in Sec. 63.562(b)(2), (3), and (4) shall comply with the 
following provisions:
    (1) Maintain records of all measurements, calculations, and other 
documentation used to identify commodities exempted under 
Sec. 63.560(d);
    (2) Keep readily accessible records of the emission estimation 
calculations performed in Sec. 63.565(l) for 5 years; and
    (3) Submit an annual report of the source's HAP control efficiency 
calculated using the procedures specified in Sec. 63.565(l), based on 
the source's actual throughput.
    (4) Owners or operators of marine tank vessel loading operations 
specified in Sec. 63.560(a)(3) shall retain records of the emissions 
estimates determined in Sec. 65.565(l) and records of their actual 
throughputs by commodity, for 5 years.
    (k) Leak detection and repair of vapor collection systems and 
control devices. When each leak of the vapor collection system, or 
vapor collection system, and control device is detected and repaired as 
specified in Sec. 63.563(c) the following information required shall be 
maintained for 5 years:
    (1) Date of inspection;
    (2) Findings (location, nature, and severity of each leak);
    (3) Leak determination method;
    (4) Corrective action (date each leak repaired, reasons for repair 
interval); and
    (5) Inspector name and signature.
