## Text

SUMMARY: Title IV of the Clean Air Act (the Act) authorizes the
Environmental Protection Agency (EPA or Agency) to establish the Acid
Rain Program. The purpose of the Acid Rain Program is to significantly
reduce emissions of sulfur dioxide and nitrogen oxides from utility
electric generating plants in order to reduce the adverse health and
ecological impacts of acidic deposition (or acid rain) resulting from
such emissions. On January 11 and March 23, 1993, the Agency
promulgated final rules governing permitting, the allowance system,
continuous emissions monitoring, excess emissions, and appeal
procedures.
After considering its experience in applying these rules since
1993, the Agency believes that the permitting, excess emissions, and
appeal procedures rules (as well as minor aspects of the monitoring
rule) can be streamlined and improved in order to reduce the burden on
utilities, State and local permitting authorities, and EPA. The rule
revisions in today's proposal streamline the Acid Rain Program while
still ensuring achievement of its statutory goals of reducing sulfur
dioxide and nitrogen oxides emissions.
In addition, EPA is revising allocations of sulfur dixoxide
allowances. Each allowance authorizes the emission of one ton of sulfur
dioxide. Under the Acid Rain Program, utility units (i.e., fossil fuel-
fired boilers or turbines) are allocated allowances and must not emit
sulfur dioxide in excess of the amount authorized by the allowances
that they hold. EPA proposes to revise certain units' allowances in
response to litigation, in light of Agency errors in making the
allocations or errors in data relevant to whether facilities are
covered by the Acid Rain Program, or because of more recent information
concerning the construction or commercial operation of new units.

DATES: Comments on the regulations proposed by this action must be
received on or before January 27, 1997.

I. Part 72: Applicability of and Exemptions From Acid Rain Program

A. Revisions Concerning Applicability

Section 72.6 explains what types of units are ``affected units''
subject to emissions reduction or limitation

[[Page 68341]]

requirements and other requirements of the Acid Rain Program and what
types of units are not affected units. Under Sec. 72.6(b) (5) and (6),
qualifying facilities and independent power production facilities
meeting certain requirements are not affected units. One such
requirement is that the facility had, as of November 15, 1990, a
qualifying power purchase commitment, which may be in the form of a
letter of intent that is followed by a power sales agreement. Under
section 405(g)(6)(A) of the Act, the power sales agreement must be
executed ``within a reasonable time'' following the letter of intent.
In July 1992 (57 FR 29940, 29947 (July 7, 1992)), EPA proposed a two-
year deadline or no later than November 15, 1992 for execution of the
power sales agreement. That deadline was not commented on and was made
final in March 1993 (58 FR 15634, 15648 (March 23, 1993)).
Subsequently, EPA has received public comment that the two-year
deadline created a hardship for independent power producers negotiating
with multiple regulated purchasers.
To implement the statutory language regarding the time frame for
execution of a power sales agreement, EPA could set a fixed deadline
(as in the current rule) or could determine a reasonable time frame on
a case-by-case basis as part of an applicability determination.
Particularly where questions of the applicability of the Acid Rain
Program are involved, EPA maintains that it is preferable to establish
clear-cut lines. Moreover, EPA is concerned that the two-year period in
the current rule for execution of an agreement does not take account of
the time necessary to complete agreements where multiple utility
purchasers are involved.
Therefore, EPA is proposing to revise the deadline to three years
from letter of intent to execution of a power sales agreement. Since
under section 405(g)(6)(A) of the Act, the letter of intent must be in
place by November 15, 1990, this means that the power sales agreement
must have been executed by November 15, 1993, rather than by November
15, 1992 as under the current rule. Public comment indicates that the
additional year is reasonable for independent power producers
negotiating with multiple regulated purchasers. EPA requests comments
on this revision.
Section 72.6(c) sets out procedures for petitioning for a
determination from the Administrator as to whether a unit is an
affected unit covered by the Acid Rain Program. The current regulation
allows the submission of the petition by a certifying official, rather
than requiring that the unit have a designated representative who would
make the submission. However, the regulation has a general reference
to, and requires compliance with, Sec. 72.21, which requires that
submissions be made by a designated representative and include certain
certifications. To prevent confusion, EPA proposes revisions that
pinpoint the certification and notice requirements in Sec. 72.21 that a
certifying official's petition must meet. In addition, language is
added to Sec. 72.6(c)(1) to clarify that it is the certifying official
of an owner or operator of a unit that may submit a petition, and some
superfluous language is removed. Further, this section is revised to
allow a petition to be submitted at any time but indicating that, if
possible, the petition should be submitted before the issuance of an
Acid Rain permit. While EPA wants to facilitate the submission of
petitions where owners or operators are uncertain as to the status of
their unit under the Acid Rain Program, EPA's determination on the
petition may obviate the processing and issuance of a permit for the
unit.

B. Revisions to Exemptions

In the current rule, EPA established two exemptions from Acid Rain
Program requirements. First, in Sec. 72.7 EPA provided for an exemption
from requirements concerning permitting, allowances, and continuous
emissions monitoring for small, new units (i.e., units that commence
commercial operation on or after November 15, 1990 and serve generators
with a total nameplate capacity of 25 MWe or less) burning clean fuels.
The exemption was adopted because emissions from these units were
considered to be de minimis. 58 FR 3390, 3594 (January 11, 1993).
Second, in Sec. 72.8 EPA provided for an exemption from Phase II
permitting requirements for affected units that retire permanently
prior to the issuance of a Phase II Acid Rain permit. Units that
submitted petitions for such an exemption could also be exempted from
monitoring requirements under Sec. 75.67.
1. Fuel Use and Fuel Testing Requirements Under New Units Exemption
EPA is proposing to modify the limitation on fuel use and the
requirements for fuel testing under the new units exemption. Under the
current rule, units must use exclusively fuels with a sulfur content of
0.05 percent or less by weight, and specified tests to measure sulfur
content must be performed for each delivery of fuel (other than natural
gas, which is presumed to meet the sulfur content requirement). The
records of such tests must be retained at the source for 5 years.
In contrast, today's proposal requires units to use only gaseous
fuel with an annual average sulfur content of 0.05 percent by weight or
less and only nongaseous fuel that separately meets this same annual
average sulfur content limit. The proposal includes formulas for
calculating the annual average percentage sulfur content by weight for
gaseous fuels and for nongaseous fuels. Similar to the approach in the
current rule requiring sampling and sulfur content testing of fuel
deliveries, the formulas require use of the measured sulfur content of
periodic samples of fuel deliveries during the year to calculate the
annual average sulfur content of fuel burned during the year. The
formulas require sampling of fuel at least once for each delivery or,
for fuel that is delivered to the unit continuously by pipeline, at
least once each quarter that the fuel is delivered. Unlike the current
rule, the formulas do not require the use of any specific testing
methods to measure sulfur content. Sampling and testing of sulfur
content of fuel, which may be performed by the fuel supplier rather
than the unit's owners and operators, are necessary in order to
demonstrate whether the sulfur content limit is met. As under the
current rule, the owners and operators of an exempt unit bear the
burden of proving compliance with the requirements of the exemption.
However, if the only gaseous fuel burned is natural gas, the
proposal provides that the 0.05 percent annual average limit for
gaseous fuel is assumed to be met without making any calculations or
conducting any sampling or testing. This is consistent with the current
Sec. 72.7(d)(2)(ii), which provides that natural gas (which is defined
as a ``fluid mixture of hydocarbons containing'', inter alia, 20 grains
or less of sulfur (40 CFR 72.2)) is assumed to meet the 0.05 percent
limit on each delivery of fuel. Moreover, consistent with the current
rule, which excludes (through the 0.05 percent sulfur content limit on
each delivery) any use of coal by the units, and because the sulfur
content of a coal delivery is not necessarily uniform, the proposal
expressly bars the use of coal or coal-derived fuel (except coal-
derived gas with a sulfur content no greater than natural gas) by
exempt units.
EPA believes that the fuel use and testing requirements in the
proposal are sufficiently stringent to ensure that minimal emissions
from the exempt units and are significantly less

[[Page 68342]]

burdensome for the owners and operators of the units involved, which in
many cases are municipally owned units. Allowing a unit to burn some
fuel that exceeds 0.05 percent sulfur by weight so long as the annual
average sulfur content of its fuel (weighted by the weight of the fuel)
does not exceed that level will have little effect on the total
SO2 emissions for the year. Separate sulfur content limits are
established by gaseous and nongaseous fuels so that very clean gaseous
fuel (e.g., pipeline natural gas) cannot be used to offset nongaseous
fuel with a sulfur content significantly higher than 0.05 percent. EPA
notes that, under this approach, a unit will be able to use landfill or
digester gas, which has a higher sulfur content than natural gas but
lower than some nongaseous fuels.1 Using the annual average will
give owners and operators more flexibility in that a single delivery of
fuel in excess of the limit will not automatically invalidate the
exemption, as is the case under the current rule.
---------------------------------------------------------------------------

\1\ This is consistent with EPA's efforts to encourage use,
rather than flaring, of such gas. See section V of this preamble.
---------------------------------------------------------------------------

EPA also believes that prescribing more detailed testing methods is
unnecessary because the appropriate testing methods may vary depending
on the specific fuel involved and testing data from the fuel supplier
may be sufficient to establish the sulfur content of the fuel.2
The proposal requires owners and operators to keep records for 5 years
(or longer if required in writing by EPA or the permitting authority)
that demonstrate that the sulfur content limit has been met. This
approach gives owners and operators more flexibility to determine what
type of information will support such a demonstration, but the proposal
also emphasizes that the burden of proof is on the owners and
operators.
---------------------------------------------------------------------------

\2\ With the elimination of the fuel testing requirements in the
current rule, the testing methodologies specified in the current
Sec. 72.7 and incorporated by reference in the current Sec. 72.13
are unnecessary, and EPA therefore proposes to remove them. The
provisions of Sec. 72.13 are renumbered to reflect this change.
---------------------------------------------------------------------------

2. Administration of New Units Exemption
The purpose of the exemption, of course, is to relieve owners and
operators of the burden of complying with permitting, allowance, and
monitoring requirements for clean new units and to reduce the
concomitant administrative burden on permitting authorities. In issuing
new unit exemptions under the current rule, the Agency has found that
the procedures for obtaining and maintaining an exemption are somewhat
less burdensome than the procedural requirements for units required to
have Acid Rain permits. However, the Agency has concluded that the
exemption procedures are still more burdensome than necessary. In
particular, the current rule provides that: a potentially exempt unit
must have a designated representative and submit a petition for a
written exemption; the permitting authority must issue a written
exemption after providing public notice (e.g., in a local newspaper)
and a comment period; and the exemption must be renewed every five
years.
The current rule requires a significant amount of processing for
each unit that seeks to obtain an exemption. The Agency has already
granted about 130 new unit exemptions using current procedures, and,
despite extensive public notice, not one comment has been received
during the public comment periods. Based on its experience with these
exemptions, EPA does not believe that requiring a designated
representative to be appointed for each clean unit and submission and
processing of forms for a new units exemption every five years provides
any significant environmental benefit.
The proposal makes the new unit exemptions largely automatic for
those units that meet the criteria, discussed above, concerning
capacity, annual fuel use, and recordkeeping. In general, no designated
representative, petition for exemption, or renewal petition is
required.3
---------------------------------------------------------------------------

\3\ Because the proposed new units exemption and, as discussed
below, the proposed retired units exemption, are automatic and
written exemptions for these units are no longer issued, the
references in the current part 72 to written exemptions under
Secs. 72.7 and 72.8 are revised. The revisions to these references
also reflect, in some cases, the establishment of exemptions for
industrial units under proposed Sec. 72.14, which is discussed
below. For example, the criteria for State acid rain programs in
Sec. 72.72(b) are changed to remove the reference to Secs. 72.7 and
72.8 written exemptions and to refer instead to Sec. 72.14
exemptions. By further example, the reference in Sec. 72.9(c)(6) to
Secs. 72.7 and 72.8 written exemptions is changed to refer to
exemptions under Secs. 72.7, 72.8, and 72.14. The same change--and
the only change proposed to part 74--is proposed in Sec. 74.2.
---------------------------------------------------------------------------

The only exception to this approach is for units that are listed
and allocated one or more allowances on Table 2 or 3 of Sec. 73.10.
Because they are being exempt from the requirement to hold allowances
to cover emissions, they should not retain their allowance allocations.
The proposal requires the designated representative (who handle the
unit's allowance account) to submit to EPA and the State permitting
authority a statement that: the unit meets, and will continue to meet,
the exemption requirements; he or she is surrendering allowances in the
same amount, and of the same or earlier compliance use date as, the
unit's allocated allowances; and he or she is returning the proceeds
for any allowances withheld from the unit for EPA allowance auctions
under subpart E of part 73. However, apparently because the owners and
operators of some small units are small entities and not fully aware of
their obligations under the Acid Rain Program, some potentially exempt
units have still not selected designated representatives even though
the units are allocated allowances. In order to facilitate
implementation of the exemptions by small entities, the proposal
provides that, if there is no designated representative, a certifying
official of each owner of the unit may make this submission. This
reflects the desirability of ensuring that each owner (or the
designated representative representing all owners) is aware of the
allowance surrender. The unit will not be exempt until EPA actually
deducts the allowances from the unit account in the Allowance Tracking
System and receives the allowance auction proceeds. Upon deduction of
the allowances, the unit account is closed.
Although units that meet the exemption criteria and are not
allocated allowances are automatically exempt, the proposal requires
the designated representative (or a certifying official of each owner)
of such unit to submit to EPA and the State permitting authority a
statement that the unit meets and will continue to meet the exemption,
which are referenced in the statement. EPA anticipates providing a
standard form for designated representatives or certifying officials
for exempt units (whether or not they have allocated allowances) to
submit the appropriate information. Providing this type of notice to
EPA and the State permitting authorities imposes little burden on the
exempt units and has important benefits. First, owners of the units are
more likely to consider carefully the basis for the exemption and the
continuing requirements under the exemption if each owners'
representative must sign and submit such a form. Second, submission of
the form will ensure that EPA and State permitting authorities can keep
track of which units are exempt and will not treat such units as
affected units.
Under the proposal, a new units exemption is effective on January 1
of the first full calendar year for which the unit meets the criteria
for an exemption.

[[Page 68343]]

This reflects the annual nature of the Acid Rain Program. As provided
in the current rule, the exemption terminates automatically when the
unit involved no longer satisfies the criteria for an exemption.
Consistent with the approach taken with other exclusions of units from
the Acid Rain Program, a unit that had an automatic exemption that
terminates is an affected unit and cannot requalify for the exemption.
See 40 CFR 72.6(a)(3)(ii) through (vii). As in the current rule,
exemption termination subjects the unit to the permitting, allowance,
and monitoring requirements of the Acid Rain Program. The unit will
have to have a designated representative, who must submit a complete
permit application before the later of January 1, 1998 or 60 days after
the exemption terminates. The unit will have to comply with the
monitoring requirements within 90 days after the termination.
Under the current rule, exempt units are still included in the
definition of ``affected unit.'' As a result, they must generally be
included in title V operating permits issued by State permitting
authorities under part 70 and are not eligible to become opt-in units
under part 74. Part 70 requires sources with affected units to have
operating permits reflecting Acid Rain Program requirements and any
other Clean Air Act requirements to which the sources are subject. If a
unit is subject to other Clean Air Act requirements, the unit must
continue to comply with such non-title IV provisions, and this will be
reflected in the title V operating permit.4 However, if a unit is
not subject to any other Clean Air Act requirements and the unit is
exempt from Acid Rain permitting, allowance, and monitoring
requirements, question has been raised as to whether the current rule
can be read to require the unit to obtain a title V operating permit.
In such circumstances, it makes little sense to require a title V
operating permit; after all, the only requirements put in the permit
will be those for maintaining an exemption and a major purpose of the
exemption is to relieve the unit and the permitting authority of
permitting burdens. Although the Agency maintains that a title V
operating permit is not required for such a unit, the proposal modifies
Sec. 72.6(b) to make this explicit by stating that any exempt new unit
is an unaffected unit. Further, because the purpose of the exemption is
to relieve clean, new units of permitting and other Acid Rain
requirements, EPA continues to believe that exempt units should be
excluded from applying to re-enter the Acid Rain Program as opt-in
sources and the proposal contains such an exclusion.
---------------------------------------------------------------------------

\4\ In order to ensure that owners and operators understand
this, today's proposal states this expressly. The proposed rule also
provides that a permitting authority may use the administrative
amendment procedures under Sec. 72.83 to add to the permit an
exemption under Sec. 72.7, 72.8, or 72.14.
---------------------------------------------------------------------------

Finally, as discussed above, EPA has already approved a number of
written exemptions for new units under the current rule. Since the
proposal provides more flexible requirements for qualifying for and
maintaining the exemption (e.g., more flexible sulfur content
requirements and no renewal requirement), the units with written
exemptions also qualify for the automatic exemption under today's
proposal. The proposal makes this clear by including, as one category
of units that qualify for the automatic exemption, those new units that
have already been granted written exemptions. EPA sees no reason for
denying already exempt units the flexibility and streamlining benefits
of the proposal and also sees no purpose to retaining permanently two
different types of new units exemptions. Consequently, the proposal
provides that already exempt units must meet the requirements for
maintaining an automatic exemption, in lieu of the requirements
contained in the current rule.
However, while the current rule requires exempt units to surrender
any allowances allocated to the units under Sec. 73.10 for years for
which the units are exempt, the written exemptions already granted did
not extend beyond 5 years. The already exempt units have not yet
surrendered Phase II allowances and, under the current rule, will have
to do so when the exemption is renewed. In extending automatically
these exemptions and removing the need for renewal, the proposal
requires those exempt units with allocated allowances to surrender such
allowances and the proceeds from EPA's auctioning of such allowances.
3. Retired Units Exemption
While retaining the basic criteria in the current rule for
qualifying for the retired units exemption, EPA proposes to streamline
the procedures for obtaining and maintaining the exemption. In
addition, EPA proposes to clarify what Acid Rain requirements are
covered by the exemption.
The current rule requires largely the same procedures for the
retired units exemption as for the new units exemption: submission of a
petition, issuance of a written exemption subject to public notice and
comment, and submission of a renewal petition every 5 years. EPA has
approved about 155 retired units exemptions under these procedures
without receiving any public comments on them. Since the purpose of the
exemption is to reduce the burden on the owners and operators of
retired units and the permitting authorities, EPA believes that, as in
the case of new units exemptions, the procedures for retired units
exemptions can be made less burdensome.
The proposal takes essentially the same approach in setting revised
procedures for both new units and retired units exemptions. The
proposed retired units exemption is automatic so long as the unit meets
the criteria for the exemption: i.e., that the unit is permanently
retired and does not emit any SO2 or NOX starting on the
effective date of the exemption. Units that retire are not, of course,
necessarily small and, since they probably have been participating in
the Acid Rain Program until retirement, probably have designated
representatives. Under the proposal, the designated representative of
each exempt unit must submit to EPA and the State permitting authority
a statement that the unit meets, and will continue to meet, the
exemption requirements. EPA anticipates providing a standard form for
the designated representative of an exempt unit to submit the
appropriate information. Units already granted retired units exemptions
also qualify for the automatic exemption and will make no additional
submissions. As under the current rule, exempt retired units retain
their allocated allowances since, even without the exemption, they
would have no SO2 emissions and would not use any allowances. An
exempt unit's Allowance Tracking System account is subject to the
requirements for general accounts under part 73. The owners and
operators of the unit must retain at the source records demonstrating
that the unit qualifies for the exemption. The exemption terminates
automatically if the unit resumes operation and emits any SO2 or
NOX.
EPA is also proposing to modify the current rule to clarify what
Acid Rain requirements are covered by the exemption. Currently
Sec. 72.8 of the regulations exempts retired units only from the
requirements of part 72. Section 75.67(a) currently provides that units
that retire before January 1, 1995 and for which a petition for a
retired units exemption is submitted prior to monitor certification
deadlines may also obtain an exemption from the monitoring requirements
of part 75. The Agency maintains that any unit that retires should be
automatically exempt, starting in the first full year of

[[Page 68344]]

retirement, from both the Phase II permitting requirements of part 72
and the monitoring requirements of part 75 so long as the unit remains
retired. If the unit has no emissions, there is nothing to monitor. The
proposal removes Sec. 75.67(a) and adds the monitoring exemption to
Sec. 72.8.
However, as noted above, retired units may still receive allowance
allocations. Such units must remain subject to subpart B of part 73,
which governs allowance allocations. Reflecting these considerations,
the proposal exempts retired units from all Acid Rain Program
requirements except for the provisions of Secs. 72.2 through 72.6,
Sec. 72.8, Secs. 72.10 through 72.13, and subpart B of part 73.
Moreover, retired units that, but for the exemption under Sec. 72.7,
would be Phase I units, must still comply with the requirements
concerning Phase I Acid Rain permits and reduced utilization of such
units during Phase I.5 The purpose of the retired units exemption
is to exempt the units from Phase II permitting, not to allow them to
avoid requirements implementing statutory permitting and reduced
utilization provisions. In fact, the retired unit exemptions issued by
EPA under the current Sec. 72.8 state expressly that they apply to
Phase II (as distinguished from Phase I) permitting requirements. In
order to clarify that reduced utilization requirements apply to units
with retired unit exemptions, the proposal states that the units must
submit annual compliance certification reports that include the
accounting for reduced utilization and are subject to end-of-year
allowance deduction procedures for Phase I years.
---------------------------------------------------------------------------

\5\ The definition of ``Phase I unit'' in Sec. 72.2 is revised
to make it clear that units that, but for a retired units exemption,
would be subject to an Acid Rain emission reduction requirement or
limitation continue to be treated as Phase I units.
---------------------------------------------------------------------------

For the same reasons as under the proposed new units exemption, EPA
proposes that units under the retired units exemption be unaffected
units and that they be excluded from becoming opt-in sources.
Similarly, retired units already granted written exemptions will be
covered by the automatic exemption and must comply with the
requirements for maintaining such an exemption.
4. Industrial Units Exemption
The purpose of title IV is to reduce the adverse impacts of acid
deposition through reductions of SO2 and NOx emissions.
Congress addressed SO2 emissions of both ``utility units'' and
``industrial sources.'' While ``utility units'' are generally required
(starting in Phase I, if the unit is listed in Table A of section 404
or is otherwise a Phase I unit, or Phase II) to meet SO2 emissions
limitations and to hold allowances to cover their SO2 emissions,
``industrial sources'' are not specifically required to limit emissions
or hold allowances. Instead, section 406 of the Clean Air Act
Amendments of 1990 required the Administrator to prepare and submit to
Congress a report that inventories national annual SO2 emissions
from industrial sources. Whenever the inventory indicates that such
emissions ``may reasonably be expected to exceed 5.6 million tons per
year,'' the Administrator must ``take such actions under the Clean Air
Act as may be appropriate to ensure that such emissions do not exceed''
the 5.6 million ton cap. 42 U.S.C. 7656. These actions may include
promulgation of standards of performance for new or existing sources.
The statutory definitions of ``utility unit'' and ``industrial
source'' draw the line between facilities (utility units) that are
subject to the requirement to hold allowances by no later than January
1, 2000 and industrial sources that are not, but could be, made subject
to unspecified requirements if the industrial source cap is exceeded.
However, ``utility unit'' is broadly defined in section 402 of the Act
to encompass units owned by companies that are generally not treated as
full-fledged public utilities by State and federal utility regulatory
authorities.
Generally, for purposes of State utility regulation, a public
utility is an entity that owns or operates facilities whose product or
service is dedicated to public use. Typically, the company must devote
its facilities to serve the general public or a portion of the general
public, not simply selected contract customers.6 In contrast,
under section 201(e) of the Federal Power Act, any persons that sell
electricity that is in turn resold are ``public utilities'' and are
subject to regulation of their sales rates and other matters by the
Federal Energy Regulatory Commission (FERC). While holding that
industrial companies that sell utilities incidental amounts of
electricity from non-cogeneration units are themselves public
utilities, FERC has imposed less burdensome regulatory requirements on
such industrial sellers. For example, rate schedules for sales by these
industrial sellers must be filed with FERC but the rates are not
required to meet traditional cost-of-service standards, under which a
rate must be based on the seller's costs (including return on capital)
of providing the electricity. See, e.g., Ford Motor Co. and Rouge Steel
Co., 50 FERC para. 61,426 (1990), modified on reh'g, 50 FERC para.

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

Under section 402 of the Clean Air Act, a utility unit is ``a unit
that serves a generator in any State that produces electricity for
sale,'' regardless of the amount of the sale relative to total
generation by the unit or generator or whether the sale is to the
general public or to a public utility for resale to the public. 42
U.S.C. 7651a(17)(A). Consequently, entities (such as independent power
producers, small power producers, and cogenerators) that sell
electricity to a public utility are affected units unless they qualify
for an exemption under other provisions of title IV. Section 402(17)(C)
establishes an exemption for units cogenerating steam and electricity:
a cogeneration unit is not a ``utility unit'' unless

the unit is constructed for the purpose of supplying, or
commences construction after [November 15, 1990] and supplies, more
than one-third of its potential electric output capacity and more
than 25 megawatts electrical output to any utility power
distribution system for sale. 42 U.S.C. 7651a(17)(C).

In addition, section 405(g)(6) establishes an exemption for ``qualifing
small power production facilities'', ``qualifying cogeneration
facilities'', and ``new independent power producers''. 42 U.S.C.
7651d(g)(6). Such entities (which are defined in sections 405(g)(6) and
416(a)(2)) that had a committment--through a power sales agreement, a
order of a State regulatory authority, a letter of intent, or selection
as a winning bidder in a competitive bid

[[Page 68345]]

solilcitation--as of November 15, 1990 to sell power are not affected
units. There are no such exceptions for industrial units that do not
fall within the exempt categories of units under these sections.
As a result, the requirements of title IV cover non-cogeneration
industrial units serving generators that produce electricity almost
exclusively for use by an industrial company and only incidentally for
sale to a public utility. In one such case, three units and three
generators (with a total nameplate capacity of about 190 MWe) are owned
and operated solely by the industrial company. Under the
interconnection agreement with a public utility and a related power
purchase agreement, the public utility provides additional electricity,
through backup and emergency service, for use by the industrial
company. The industrial company is in turn obligated to sell some
electricity on a backup and emergency basis to the public utility and,
starting in 1984, has made such sales, which have been less than 10
percent of total annual generation. The industrial company obtains
backup for its capacity, and the public utility avoids constructing
some additional capacity. Because these industrial units make limited
electricity sales only to the public utility, the company is apparently
not regulated by the State utility regulatory authority and is subject
to relatively light-handed FERC regulation. EPA has received public
comment suggesting that the units be exempt from the Acid Rain Program.
In order to determine the scope of the issue, EPA attempted to
estimate the number of units that might be covered by such an exemption
for industrial units. About 3,400 industrial combustion sources are
included in the 1990 Interim Inventory (a database based on the 1985
NAPAP inventory with emissions projections for 1995). EPA removed, from
this group of possibly affected industrial units, those industrial
units thought to be: self-generators consuming rather than selling
their generation; cogenerators exempt under section 402(17)(C); or
units exempt under section 402(b) because they were serving only
generators with a nameplate capacity of 25 MWe or less. EPA estimated
that about 140 remaining industrial units possibly may be affected
units under title IV. Based on discussions with industry
representatives and on review of the electric rate schedules filed at
FERC for electricity sellers that are not traditional utilities, EPA
concludes that most of these remaining industrial units are not selling
any electricity and that there are about 15 industrial units that sell
some electricity and so are affected units under the current Acid Rain
rules. See Report to Docket: Industrial Units.
Even if electricity sales to a public utility make up a very small
portion of the total amount of electricity produced by an industrial
unit and associated generator, the Acid Rain Program imposes allowance
requirements relating to all SO2 emissions from the unit. In such
a case, no distinction is made between emissions associated with the
small amount of electricity sales and emissions associated with the
vast majority of electricity used by the industrial company itself. An
affected industrial unit must hold allowances, as of the allowance
transfer deadline, that cover all of the unit's SO2 emissions
during the year. 40 CFR 72.9(c)(1)(i). Similarly, any NOx emission
limitation applicable to the industrial unit covers all NOx
emissions from the unit. See, e.g., 40 CFR 76.5, 76.6, and 76.7.
The cost to some industrial companies of holding sufficient
allowances may be exacerbated by the fact that, even though certain
existing industrial units could have qualified for allowance
allocations for Phase II under section 405 of the Act, none were
allocated any allowances. See 40 U.S.C. 73.10 (Tables 2 and 3, which do
not include any such units). Information on such units was not included
in the National Allowance Data Base (NADB), which was used to develop
allowance allocations. However, based on information compiled by the
Department of Energy on electric generators owned by nonutility
electric power producers, EPA developed and published the Adjunct Data
File, which listed units owned by ``nontraditional'' utilities. 57 FR
30034, 30040 (July 7, 1992). EPA noted that the listed facilities
potentially could be affected units, but that it did not have
sufficient information to make an applicabililty determination or to
allocate allowances to those that were affected units. Consequently, in
publishing the file, EPA requested owners or operators of units that
were then or might, in the future, become affected units to provide EPA
the data elements necessary for allocating allowances. In addition, EPA
gave notice that if the data was not provided by September 8, 1992, the
units involved would not be allocated any allowances and, to the extent
allowances were needed, would have to obtain them on the open market.
Id. A number of industrial companies submitted comments on the Adjunct
Data File, each arguing that their units were not affected units.
On March 23, 1993, EPA issued a notice stating that (with a few
exceptions not relevant here) that it ``believes'' that none of the
units in the Adjunct Data File were affected units. 58 FR 15720, 15727
(March 23, 1993). No allowances were allocated to industrial units in
the Adjunct Data File (including some units identified in Report to
Docket: Industrial Units as potentially covered by the proposed
industrial unit exemption) or to any other industrial units. However,
EPA stressed that the omission of a unit from the tables indicating
allowance allocations does not mean that the unit is an unaffected
unit: ``[a]pplicability will be determined under the (Acid Rain) rules
in 40 CFR 72.6.'' Id.
In addition to being required to hold allowances covering all
SO2 emissions and to meet any applicable NOx emission
limitation, an affected industrial unit, like all affected units, must
install, operate, and maintain continuous emission monitoring systems
for all SO2, NOx, and CO2 emissions and for opacity.
After EPA approves certification of the systems, they must be tested
periodically to ensure that the monitoring data is accurate. Further,
monitoring data (including hourly emissions data) must be reported to
EPA on a quarterly basis. The average cost per unit of acquisition,
installation, operation, and maintenance of a continuous emission
monitoring system (including data handling hardware) is estimated to be
about $90,600 (in 1993 dollars). Economic Analysis of the Title IV
Requirements of the 1990 Clean Air Act Amendments at 34 (ICF Resources
Inc. 1995) (estimating total annualized emission monitoring costs under
title IV of $200 million for 2,096 units during the period 1997-2010).
The costs of the Acid Rain Program are more likely to be a problem
for industrial companies than for public utilities, which in general
have greater ability to pass through to customers the costs of
acquiring allowances. First, public utilities generally are subject to
cost of service ratemaking and charge rates covering their costs of
service. Second, virtually all fossil fuel-fired utility generation is
covered by the Acid Rain Program. In contrast, the prices charged by
industrial companies for their industrial products are generally
limited by competitive market prices and relatively few industrial
units are covered by the program. Particularly if one industrial
company, but not its competitors, must meet the costs of the Acid Rain
Program as applied to its units, market prices will not necessarily
cover all such costs. EPA notes that in

[[Page 68346]]

section 405(g)(6)(A) cogeneration units that, as of November 15, 1990,
had already contracted or otherwise committed to sell electricity to a
public utility were exempted from the Acid Rain Program because of
their limited ability to pass through allowance costs to customers. 58
FR 15634, 15638 (March 23, 1993); see also Cong. Rec. S3027-28 (March
22, 1990).
In short, as a result of a very small portion of its operations
(i.e., incidental electricity sales to public utilities under existing
interconnection and power purchase agreements), a non-cogeneration
industrial unit may be subject to allowance and monitoring requirements
affecting all of its electric generation activities and imposing
significant costs.7 Further, once the industrial unit has begun
making any such incidental electricity sales, the unit becomes an
affected utility unit permanently subject to all the requirements of
the Acid Rain Program. In the absence of an exemption, such a unit is
an affected utility unit if, during 1985, it served a generator that
produced electricity sold to a public utility or if, at any time
thereafter, the unit serves such a generator. See 42 U.S.C.
7651a(17)(A). The unit remains an affected utility unit even if the
industrial company subsequently terminates its interconnection
agreement with and stops selling electricity to the public utility.
---------------------------------------------------------------------------

\7\ The Acid Rain Program also requires the owners and operators
of affected industrial units to select a designated representative
and obtain an Acid Rain permit covering the units. While these
requirements impose some costs, the costs are relatively small.
---------------------------------------------------------------------------

EPA is concerned that, because of an incidental portion of the
operations of a non-cogeneration industrial unit, an industrial company
will be burdened with significant regulatory requirements and resulting
costs that were unanticipated when the incidental electricity sales
were made and that are unavoidable in that they remain even if the
incidental sales are now terminated. However, this concern applies only
where (1) the industrial units are not cogeneration units; (2) these
units serve generators that were contractually obligated to make
incidental sales under an interconnection agreement (and any related
power purchase agreement) and have made only incidential electricity
sales; and (3) this contractual obligation was effective on or before
March 23, 1993. This new exemption is not necessary for cogeneration
units since Congress already provided an exemption for cogeneration
units based on the amount of utility sales. Moreover, non-cogeneration
industrial units making more than incidental electricity sales should
be affected units since, in title IV, Congress generally applied the
Acid Rain Program to units serving generators that sell electricity.
The basis for limiting the exemption to units under a contractual
obligation as of March 23, 1993 is related to the Agency's handling of
allowance allocations for industrial units. After November 15, 1990,
industrial units' owners were on constructive notice that if they
contractually obligated themselves to sell electricity, they would be
subject to title IV requirements. However, as noted above, on March 23,
1993 EPA issued a notice stating that it believed that the industrial
units listed in the Adjunct Data File (a list of units owned by
``nontraditional utilities'') were unaffected units. 58 FR 15727. The
notice did not explain the basis for this ``belief'', which appears to
have been erroneous with regard to at least some of the listed
noncogeneration industrial units. As a result, EPA did not add the
industrial units to the allowance allocation tables and did not
allocate any allowances to these units. Id. Also on March 23, 1993, EPA
issued a final list of the Phase II allowance allocations under section
403(a) of the Act.8 58 FR 15634 (March 23, 1993). As discussed
below, EPA is today correcting certain Agency errors in the March 23,
1993 allocations. However, except for these limited corrections, EPA
will not allocate allowances to units that were not listed as receiving
allowance allocations in the March 23, 1993 notice and that become
affected units after that date. 58 FR 15641. Consequently, if, after
March 23, 1993, a non-cogeneration industrial unit becomes
contractually obligated to sell electricity to a utility and, by making
the sales, becomes an affected unit, the unit will not be allocated
allowances. Non-generation industrial units that were contractually
obligated on or before March 23, 1993 and were affected units probably
should have been, but were not, allocated allowances. Therefore, EPA
proposes to apply the new exemption to non-cogeneration industrial
units that were contractually obligated as of March 23, 1993.
---------------------------------------------------------------------------

\8\ Section 403(a) required the final list of allowance
allocations to be published by December 31, 1992, but the final list
was issued late.
---------------------------------------------------------------------------

Under this approach, the non-cogeneration industrial units that
meet the exemption criteria and are issued an exemption may continue to
serve generators making incidential, contractually required electricity
sales and remain exempt. However, if the units serve generators that
make sales after the contractual obligation is no longer in effect or
to make sales beyond the contractual obligation, the units will become
affected units under the Acid Rain Program.
Exempting non-cogeneration industrial units will exempt their
SO2 emissions from the requirement to hold allowances and thus
from the 8.95 million ton cap in Phase II for utility units. The total
estimated annual SO2 emissions from exempt industrial units are
relatively small: about 47,000 tons. Report to Docket: Industrial
Units. The environmental impact of removing these units from the
utility unit cap is mitigated by the fact that emissions from the
exempt industrial units are still subject to the 5.6 million ton cap
for industrial sources. As discussed above, the Administrator is
required to take action under section 406 of the Clean Air Act
Amendments of 1990 to ensure that the industrial source cap is not
exceeded.
The industrial units exemption will also exempt these units from
Acid Rain NOX emissions limitations to the extent that the units
have coal-fired boilers of the types covered in Phase II. Again, the
total estimated annual NOX emissions from exempt units is
relatively small: about 19,000 tons. Id. In April 1995 EPA promulgated
NOX emission limitations for dry bottom wall-fired or tangentially
fired boilers. 60 FR 18751, 18763 (April 13, 1995). In January 1996,
EPA proposed to revise these limitations and establish new limitations
for most other types of existing coal-fired boilers. 61 FR 1442, 1480
(January 19, 1996).
For these reasons, EPA proposes to establish a narrow exemption for
non-cogeneration industrial units, i.e., non-cogeneration units that
have no owner or operator of which the principal business is
electricity sale, transmission, or distribution or that is a public
utility subject to State or local utility regulation. In determining
whether this requirement is met, any affiliate or subsidiary or parent
company of an owner or operator will be considered so that the
requirement cannot be circumvented through the position of the owner or
operator in a corporate structure. The exemption will apply where there
is a showing that, on or before March 23, 1993, the owners or operators
of the unit entered into an interconnection agreement (and any related
power purchase agreement) with a public utility requiring that
generators served by the unit produce electricity for sale only for
incidental sales of electricity to a public utility. There also must be
a showing that the unit served generators that, in 1985 and any year
thereafter, actually produced electricity

[[Page 68347]]

for sale only for incidental electricity sales to a public utility as
required under that interconnection agreement and any related power
purchase agreement. If any of the requirements of the exemption are not
met, the exemption terminates automatically.
Two aspects of the proposed exemption ensure that it is limited to
situations involving only incidental electricity sales. First, the
sales must be required under an interconnection agreement (and any
related power purchase agreement) between the owners or operators of
the industrial unit and the public utility to which the electricity
sales are made. The fact that the sales are made in connection with the
agreement through which the industrial company obtains electricity for
its own use from the public utility indicates that the sales are
incidental to the industrial company's business. Second, the sales to
the public utility must not exceed, in any calendar year, the lesser of
10 percent of the generating output capacity of the generator served by
the unit (which is the nameplate capacity of the generator times the
number of hours (8,760) in a year) for that year or 10 percent of the
actual annual electric output of the generator. EPA believes that these
limits on the amount of annual sales are reasonable and will help
ensure that the unit's electricity sales are truly incidental. Applying
these limits to a hypothetical industrial unit serving a generator with
nameplate capacity of 75 MWe, the generator output capacity is 657,000
MWe-hr. Assuming that the generator's actual annual electrical output
is 300,000 MWe-hr, this unit can sell up to 30,000 MWe-hr and qualify
for an industrial unit exemption under this proposal.
Because of EPA's lack of experience with this proposed exemption
and because applying the exemption criteria to specific cases may
require analysis and exercise of administrative judgment and may
benefit from public comment, EPA proposes to require submission of an
application for an exemption and provide for public notice and comment
before approving or disapproving the exemption for any industrial unit.
The designated representative of an industrial unit must submit an
application that provides the information necessary to rule on the
exemption. Using the procedures applicable to permit issuance, the
permitting authority will issue a draft exemption or denial of
exemption for public comment and then issue or deny a final exemption
(or proposed exemption if a State is the permitting authority). An
industrial unit with an approved exemption will become an unaffected
unit and will be exempt from the provisions of the Acid Rain Program,
except for the provisions of Sec. 72.14 (the new section providing for
and setting conditions on the exemption), Secs. 72.2 through 72.6,
Secs. 72.10 through 72.13. Like other exempt units, an exempt
industrial unit cannot become an opt-in source. The exemption need not
be renewed and is effective so long as the unit meets the requirements,
discussed above, for maintaining the exemption.
EPA requests comment on all aspects of the proposed industrial unit
exemption.

II. Part 72: Interaction of Acid Rain Permitting and Title V

Section 408 of the Act requires that title IV be implemented by
``permits issued to units subject to this title (and enforced) in
accordance with the provisions of title V, as modified by (title IV) .
. . No permit shall be issued that is inconsistent with the
requirements of (title IV), and title V as applicable.'' 42 U.S.C.
7651g(a).
Title V, in turn, sets forth requirements for permit programs to be
implemented by State and local air pollution control agencies. Under
title V, it is unlawful to operate an affected source in the Acid Rain
Program or other specified sources ``except in compliance with a permit
issued by a permitting authority under (title V).'' 42 U.S.C. 7652b(a).
The permit must include enforceable emission limitations and standards
and other conditions ``as are necessary to ensure compliance with
applicable requirements of (the Act).'' 42 U.S.C. 7652d(a). Title V
states that its provisions ``apply to permits implementing the
requirements of title IV except as modified by that title.'' 42 U.S.C.
7652f(b).
EPA proposes to revise the current regulations governing the
interaction of titles IV and V with regard to several matters: the
provisions explaining the relationship between the Acid Rain rules and
rules implementing title V (i.e., parts 70 and 71); establishment of
State authority to administer and enforce Acid Rain permits; and the
required elements of a State Acid Rain program.

A. Relationship Between Acid Rain Rules and Parts 70 and 71

The current part 72 states that parts 72 and 78 take precedence
over part 70 (which governs title V permitting) to the extent that any
requirements of parts 72 and 78 are ``inconsistent with'' part 70. 40
CFR 72.70(b). The current rules also state that part 72 governs Acid
Rain permitting by the Administrator but do not specifically address
the rules (i.e., part 71) for permitting by the Administrator under
title V since part 71 had not been issued when the current part 72 was
issued. See 40 CFR 72.60(a). As noted above, both titles IV and V
establish the precedence of the Acid Rain regulations over title V
regulations for purposes of administering Acid Rain permits. Since the
issuance of the current part 72 in January 1993, additional Acid Rain
regulations relating to permit administration (i.e., part 74 for opt-in
sources and part 76 for NOx emissions) have been promulgated. In
addition, part 71, setting forth permitting procedures for the
Administrator under title V, has been proposed and then issued as a
final rule. 61 FR 34202 (July 1, 1996).
EPA proposes today to revise the current provisions addressing the
relationship between Acid Rain and title V rules to reflect the
additional rulemaking activity. The revisions also clarify what
constitutes an ``inconsistency'' between the two sets of regulations
and the circumstances under which the Acid Rain rules take precedence.
With regard to State permitting activities, the proposal states in
Sec. 72.70(b) that parts 72, 74, 76, and 78 take precedence to the
extent that such parts ``contain provisions not included in, or
expressly eliminate or replace provisions of, part 70 concerning the
acid rain permit application and the Acid Rain portion of an operating
permit.'' 9
---------------------------------------------------------------------------

\9\ Language in the current Sec. 72.70(b) concerning petitions
for exemption and draft, proposed, and final written exemptions is
removed because it is redundant. The requirements for exemptions are
already included in part 72.
---------------------------------------------------------------------------

An analogous provision is proposed in Sec. 72.60(a) with regard to
permitting by the Administrator. In addition, the proposal explains
that the Acid Rain requirements concerning permit applications,
compliance plans, permit content and permit shield, permit processing
and issuance, permit revision, and administrative appeals replace the
provisions in part 71 with regard to Acid Rain permit applications and
permits. The provision also states that the part 71 provisions
concerning Indian tribes, delegation of a part 71 program, affected
State review of draft permits, and public petitions to reopen a permit
for cause are not eliminated or replaced by the Acid Rain provisions
and so apply to the Acid Rain Program.

[[Page 68348]]

B. State Authority To Administer and Enforce Acid Rain Permits

The current rule provides that if a State or local agency receives
full, interim, or partial approval of an operating permits program
under title V by July 1, 1996, that agency becomes the permitting
authority for the issuance of Phase II Acid Rain permits.See 40 CFR
72.73(a). (Under the Acid Rain Program, the term ``State'' is defined
to include the 48 continguous States, the District of Columbia, and
local authorities; henceforth in this preamble, ``State'' will be used
with that meaning.) 10 The State permitting authority must issue
Phase II Acid Rain permits by December 31, 1997. If the State operating
permits program is not approved by July 1, 1996, the Administrator is
the permitting authority for Phase II Acid Rain permits and must issue
them by January 1, 1998. After a State operating permits program is
approved, the Administrator will suspend issuance of Acid Rain permits.
See 40 CFR 72.74.
---------------------------------------------------------------------------

\10\ In the proposal, EPA is expanding the definition of
``State'' to include eligible Indian tribes in order to be
consistent with the treatment of Indian tribes that has been
proposed for parts 70 and 71. See 59 FR 43956 (August 25, 1994)
(proposed regulations implementing section 301(d) of the Act), 60 FR
45530 (August 31, 1995) (proposed revisions to part 70), 60 FR 20804
(April 27, 1995) (proposed part 71), and 61 FR 34213-4 (final part
71). To ensure that the approach taken to Indian tribes under part
72 is consistent with the approach that is ultimately adopted under
parts 70 and 71, today's proposal provides that ``eligible Indian
tribe'' be defined as in part 71. EPA's proposals concerning the
treatment of Indian Tribes were issued subject to public comment and
may be modified before they are issued in final form. EPA may need
to make conforming changes to today's proposal to reflect any
relevant revisions made to those proposals.
---------------------------------------------------------------------------

EPA has found that this approach should be modified. Some States
have submitted, and EPA has granted interim or full approval of,
operating permits programs that do not include all necessary Acid Rain
provisions. State permitting authorities that have approval but lack a
full Acid Rain program are not in a position to process, issue, and
otherwise administer properly Acid Rain permits. Further, some States
have indicated that they want to adopt some portions of the Acid Rain
Program (e.g., the permitting requirements for sources with Phase I and
Phase II units) 11 but not other portions of the program (e.g.,
permitting requirements for opt-in sources).
---------------------------------------------------------------------------

\11\ Phase I units are subject to Acid Rain emissions reduction
requirements or emissions limitations starting in Phase I. Phase II
units are subject starting in Phase II. While only Phase I units
must have Acid Rain permits for Phase I, both Phase I and Phase II
units must have permits for Phase II. Section 72.31 is revised to
clarify that Phase II permit applications must cover all affected
units at the source.
---------------------------------------------------------------------------

Consequently, EPA proposes to revise the current rule to reflect
the variety of circumstances concerning State adoption of Acid Rain
programs. Under the proposal, a State becomes responsible for
administering and enforcing Acid Rain permits for affected sources if
it has both an operating permits program approved under part 70 and
Acid Rain regulations that are accepted by the Administrator through a
notice in the Federal Register that cover the sources. (The term
``administer'' includes all aspects of processing a permit, e.g.,
issuance, renewal, and revision.) Until these requirements are met, the
Administrator will be the permitting authority for purposes of issuing
Acid Rain permits (or the Acid Rain portion of operating permits) for
the sources.
Section 408(d) of the Act requires that Phase II Acid Rain permits
be issued for sources with Phase I and Phase II units by December 31,
1997 if a State is the permitting authority. In order to allow
sufficient time for a State to meet this statutory deadline, the
proposal states that a State must have an approved operating permits
program (whether full or interim approval) and accepted Acid Rain
regulations by January 1, 1997 or such later date as the Administrator
may set (rather than a fixed date of July 1, 1996, as in the current
rule) if the State is to be the permitting authority for the initial
Phase II Acid Rain permits. Otherwise, the Administrator will be
responsible for issuing such permits. EPA has already issued notices
identifying the status of State permitting authorities' acid rain
regulations. See, e.g., 60 FR 16127 (March 29, 1995); 60 FR 52911
(October 11, 1995); and 60 FR 62846 (December 7, 1995).
If EPA is issuing permits and, after January 1, 1997, the State
meets the requirements to become the permitting authority for Acid Rain
permits, the Administrator will cease issuing Phase II Acid Rain
permits to sources in that State. However, the Administrator will
continue to administer and enforce those Acid Rain permits that he or
she has already issued until the permits are replaced by State-issued
Acid Rain permits. The State may issue replacement permits on or before
the expiration date of the EPA-issued permits. Further, the
Administrator may retain jurisdiction over the EPA-issued permits until
any administrative or judicial appeals of them are completed.
The proposal also provides flexibility where a State has proposed a
partial Acid Rain program, e.g., where the proposed program covers
permitting of Phase I and Phase II units but not opt-in sources. In
that circumstance, the Administrator may accept the State Acid Rain
regulations, issue a notice stating that the State is the permitting
authority for Phase I and Phase II units, and retain the authority to
issue permits for opt-in sources.
If a State has become the Acid Rain permitting authority but the
Administrator determines that the State is not adequately administering
or enforcing the State Acid Rain program, the proposal sets forth a
procedure for withdrawal of that program and for administration and
enforcement by the Administrator. The procedure is modeled after, but
not identical to, the analogous procedures under parts 70 and 71.
Because the Acid Rain Program relies on a nationwide, market-based
system of allowances to achieve cost-effective SO2 emissions
reductions, it is particularly important that Acid Rain requirements be
implemented in a uniform manner by permitting authorities throughout
the U.S. In order to provide the Administrator the flexibility to
respond in a timely fashion where Acid Rain requirements are not being
properly implemented, the proposal does not fix the time frames by
which a State must address deficiencies in its program or by which EPA
becomes the permitting authority. The proposal leaves it to the
Administrator to set these time frames based on the specific
circumstances.
The proposal also includes a provision under which the
Administrator may delegate to a State all or part of his or her
responsibility to administer and enforce Phase II Acid Rain permits. If
a State does not meet the requirements for acting as the Acid Rain
permitting authority (e.g., does not yet have Acid Rain regulations
accepted by EPA), the Administrator may delegate to the State the
administration and enforcement of Phase II Acid Rain permits using
regulations established by the Administrator. This approach is
analogous to the approach in part 71.12
---------------------------------------------------------------------------

\12\ The definition of ``permitting authority'' in Sec. 72.2 is
revised to include a State permitting authority to which authority
to administer and enforce Acid Rain permits is delegated.
---------------------------------------------------------------------------

Further, the current rule does not expressly address the question
of whether the provisions of Phase I or Phase II Acid Rain permits
issued by the Administrator constitute ``applicable requirements''
under part 70. It may be argued that under title V the provisions of
federally issued Acid Rain permits are ``applicable requirements''
under part 70 and therefore must be included in State-issued operating
permits. In

[[Page 68349]]

that case, a State would have to formally incorporate, in each
operating permit for an affected source, any federally issued Acid Rain
permit.
However, title IV, which supersedes title V in Acid Rain matters,
requires all Phase I Acid Rain permits to be issued by the
Administrator. There is little purpose in requiring States to duplicate
Phase I permits in their operating permits. Moreover, any revisions of
federal Phase I permits would have to be repeated for any State
operating permits that included Phase I provisions. With regard to
federally issued Phase II Acid Rain permits, the proposal explicitly
requires that States replace the federal permit with a State-issued
Acid Rain permit by the end of the five-year effective period of the
federal permit. It is unnecessarily burdensome to require State
incorporation of the federal permit in the operating permit prior to
the federal permit's expiration. To incorporate the federal permit, the
State must essentially repeat the notice and comment process that was
used to issue the federal permit in the first place. Consequently, the
proposal states that the provisions of federally issued Phase I or
Phase II Acid Rain permits shall not be ``applicable requirements'' for
purposes of part 70.
Finally, the current Sec. 72.73(b)(2) requires State permitting
authorities to reopen Phase II Acid Rain permits by January 1, 1999
``to add'' Acid Rain NOX requirements. It is unclear whether this
language requires the reopening process to be completed or simply to
begin by that date. Under part 76, Phase II NOX compliance plans
must be submitted to permitting authorities by January 1, 1998. It
seems desirable to have a deadline (prior to Phase II) by which Acid
Rain permits will include Phase II NOX requirements. However, EPA
is also concerned that State permitting authorities have sufficient
time to process the permits. EPA therefore proposes to clarify in
Sec. 72.73(b)(2) that the reopening process and the addition of
NOX requirements must be completed by July 1, 1999.13
---------------------------------------------------------------------------

\13\ A similar revision is proposed, in Sec. 72.74(c)(2), where
the Administrator is the permitting authority, except that reopening
must be completed within 6 months of submission of a complete
NOX compliance plan.
---------------------------------------------------------------------------

C. Required Elements for State Acid Rain Program

The current rule sets forth the criteria for approval of the Acid-
Rain-related provisions of State operating permit programs. The basic
approach is that the State Acid Rain program is required to comply with
part 70 requirements and the additional Acid-Rain-specific requirements
listed in Sec. 72.72(b). Where the listed requirements are inconsistent
with part 70 requirements, the listed requirements must be met in lieu
of such part 70 requirements.
EPA has carefully re-examined the listed Acid-Rain-specific
requirements with an eye to minimizing the differences between State
Acid Rain permit procedures and other State operating permit
procedures. EPA recognizes that the Acid Rain permits make up a
relatively small portion of a full State operating permit program.
Minimizing the number of unique Acid Rain requirements and reducing the
number of different procedures that must be followed will reduce the
burden on States and affected-source owners and operators. In addition,
removal of Acid Rain requirements that duplicate provisions already in
part 70 will streamline Sec. 72.72 and reduce the potential for
confusion as to whether something other than the part 70 provisions is
required.
Upon re-examination of the listed requirements in Sec. 72.72(b),
EPA believes that the following requirements are unnecessary or
redundant and proposes to eliminate or revise them in order to allow
States to streamline their Acid Rain programs and permit
administration:
1. The requirement that the State permitting authority submit to
EPA any written notice of the completeness of a permit application and
a copy of each draft permit imposes an unnecessary burden. Therefore,
EPA proposes to remove the requirement. The permitting authority
already must provide EPA copies of the application and the proposed
permit under part 70, and that seems sufficient.
2. The requirement that the permitting authority include a
statement of basis in the draft permit is redundant since that is
already required under part 70. EPA therefore proposes to remove the
provision.
3. The requirement that the permitting authority provide for public
notice of the opportunity to comment and request a hearing is proposed
to be revised to be less burdensome. First, based on its experience in
processing Phase I Acid Rain permits, EPA maintains that, where a unit
is required in a draft permit simply to comply with the standard
SO2 emissions limitation (i.e., the requirement to hold allowances
covering emissions), there is little in the portion of the draft permit
on which to comment. EPA believes that this is also the case to the
extent a draft permit for a unit subject to Acid Rain NOX
requirements imposes only the standard NOX emissions limitations
under Secs. 76.5, 76.6, or 76.7, a NOX averaging plan, or a
NOX early election plan. There is little to comment on because the
requirements for compliance in these circumstances are set forth in
detail in the rule and there is little discretion involved in adopting
such permit provisions. In contrast, other compliance options, such as
Phase II repowering plans or NOX alternative emission limitations,
have more general requirements that must be crafted to fit the unique
circumstances of the unit involved. Few, if any, comments were received
on draft Phase I permits for units that were simply adopting the
standard SO2 or NOX emissions limitations or NOX
averaging plans. The Agency also found that providing notice in a
newspaper local to each source is a time consuming and expensive
process. Consequently, if a draft permit or permit revision only
requires units to meet the standard SO2 or NOX emissions
limitations or a NOX averaging plan, EPA proposes to give
permitting authorities the discretion to give notice by serving a
notice on the appropriate list of persons and omitting publication in a
local newspaper or State publication.14
---------------------------------------------------------------------------

\14\ In addition, the specific references in the current rule
to part 70 provisions stating what persons must be served notice are
superfluous and so are eliminated.
---------------------------------------------------------------------------

Second, the proposal explicitly provides that a State permitting
authority may, in its discretion, use the so-called ``direct final''
procedure in order to meet the requirements for issuing draft permits,
providing notice and comment, and issuing proposed permits. Under the
``direct final'' procedure (which has been used by EPA in rulemakings
and other actions under the Clean Air Act) 15 the State permitting
authority may issue, as a single document, a draft Acid Rain permit and
a proposed Acid Rain permit and provide notice of the opportunity for
public comment on the draft Acid Rain permit. In the notice the State
permitting authority states that, if no significant, adverse comment on
the draft Acid Rain permit is timely submitted, the proposed Acid Rain
permit will be deemed to be issued on a specified date without further
notice. The notice also states that, if such significant, adverse
comment is timely submitted, a proposed Acid Rain permit or denial of a
proposed Acid Rain permit will be issued and the comments addressed.
This procedure streamlines the permitting process in cases where no
adverse comment is anticipated. While EPA believes that the current
rule

[[Page 68350]]

does not bar using this streamlined procedure, the proposed rule makes
explicit the option to use the procedure.16
---------------------------------------------------------------------------

\15\ See, e.g., 60 FR 18462 and 18472 (April 11, 1995).
\16\ For the same reasons, the proposed rule includes an
analogous provision in subpart F, which sets forth the Acid Rain
permit issuance procedures when the Administrator is the permitting
authority.
---------------------------------------------------------------------------

4. The requirements that the permitting authority submit a copy of
the proposed permit for review by the Administrator and affected States
and incorporate changes resolving objections to the proposed permit are
redundant since part 70 already imposes these requirements. These
provisions in Sec. 72.72(b) are unique only to the extent that they
specifically refer to issuance or denial of Acid Rain permits. EPA
believes that such reference is unnecessary because the authority to
deny a permit where basic requirements (e.g., meeting the applicability
criteria for the Acid Rain Program) are not met is obvious. EPA does
not see any reason for addressing the possibility of permit denials
differently in part 72 than in part 70 and part 71.
5. The requirement that invalidation of the Acid Rain portion of
the operating permit not affect the remaining provisions of the permit
and vice versa is redundant. Part 70 already requires that invalidation
of any operating permit provision not affect any other operating permit
provisions.
6. The limitation on the filing of State administrative or judicial
appeals of an Acid Rain permit to no more than 90 days from the
issuance of the permit to be appealed makes appeals of Acid Rain
provisions different from appeals of any other aspect of an operating
permit. Under part 70, the availability of and procedures for
administrative appeals are left entirely to the States; there are no
mandated time limitations on filing such appeals. With regard to
judicial appeals, part 70 provides that appeals may be filed after a
fixed period (which may not exceed 90 days) if the appeal is based
solely on grounds arising after the deadline. EPA has proposed to
lengthen the maximum period under part 70 from 90 to 125 days. 59 FR
44460, 44516 (August 29, 1994). EPA sees no reason for treating appeals
of Acid Rain provisions differently than appeals of other permit
provisions and is concerned that the different appeal periods may
engender confusion. Having different appeal periods could result in
different parts of the same operating permit having different deadlines
for filing appeals. The proposal eliminates the limitation on Acid Rain
appeals.
7. The requirement that a permitting authority give the
Administrator notice of administrative or judicial orders relating to
an Acid Rain permit is retained. The proposal removes language
indicating that, after issuance of such an order, the Administrator
will review and may veto the Acid Rain permit under the procedures for
reviewing proposed permits under Sec. 70.8. The language was intended
to provide for EPA review where, for example, an Acid Rain permit that
had already undergone EPA review under Sec. 70.8 was then significantly
altered on appeal. Upon reconsideration, EPA concludes that this
approach in the current Sec. 72.72 is confusing since it may put into
question whether an ostensibly final permit becomes a proposed permit
when there is a State determination (e.g., a State court order)
modifying the permit. This approach is also unnecessary since the
Administrator already has the authority to reopen permits for cause,
which authority is available in the event of such a State determination
or interpretation.17
---------------------------------------------------------------------------

\17\ For the same reasons, an analogous provision in
Sec. 72.80(e) is also removed.
---------------------------------------------------------------------------

8. The requirement that State administrative appeals not result in
the stay of any provisions that could not be stayed under part 78 is
proposed to be removed for several reasons. First, as discussed below
(in section VII of this preamble), the provision on stays in part 78 is
eliminated because, under current case law, a permit appealed under
part 78 is not a final agency action, and cannot be implemented,
pending the administrative appeal. Further, in reviewing State
operating permit programs, EPA has found that States have a variety of
administrative appeals processes. In many States the administrative
appeal precedes the issuance of a final permit and so the stay
provision in the current part 72 is meaningless. In addition, the
provision bars stays of requirements in the permit (i.e., allowance
allocations, the standard Acid Rain requirements, monitoring and
reporting requirements, and the certificate of representation) that are
imposed, under part 72 and other Acid Rain rules, independently from
the permit. Even if a source has no permit, the source must meet these
requirements. In short, the stay provision has little practical effect.
9. The requirements that State permitting authorities
``coordinate'' with utility regulatory authorities and evaluate the
sufficiency of fees supporting the State acid rain program are proposed
to be removed as unnecessary. The relationship between State agencies
is best left to the States, and part 70 fully addresses issues
concerning fees.
In reconsidering the requirements for State operating permit
programs, EPA has become aware of another issue concerning State
programs. The current rule requires that a permitting authority issue,
for each affected source, only one Acid Rain permit covering all
affected units at that source. EPA received comment that, in a few
cases, States have historically issued separate permits to units that
are at the same source but that were constructed at different times.
The States plan to continue separate permitting of the units under
their operating permits programs. Rather than requiring State
permitting authorities to restructure their permitting of such sources,
EPA proposes to give permitting authorities the discretion to allow
separate Acid Rain permit applications for, and thus to issue separate
Acid Rain permits to, the units at the source. However, this provision
does not change the designated-representative requirements for the
units: all units at the source must still have the same designated
representative and, if applicable, the same alternate designated
representative.
A large number of State permitting authorities have already adopted
Acid Rain regulations consistent with the current provisions of part
72. The most efficient and most frequently used method of State
adoption of Acid Rain regulations has been incorporation of part 72 by
reference. The part 72 rule changes proposed today are primarily aimed
at streamlining Acid Rain permitting (whether EPA or the State is the
permitting authority). EPA therefore anticipates that State permitting
authorities will want to adopt the final revisions relatively soon
after promulgation. However, EPA recognizes that revising State
regulations, even when accomplished through incorporation by reference
of the revised part 72, can be a time consuming process. Moreover,
State permitting authorities are required to issue initial Phase II
Acid Rain permits by December 31, 1997. None of today's proposed
revisions are so fundamental that a State permitting authority with
Acid Rain regulations consistent with the current part 72 should not
start or even complete the process of issuing the Phase II permits
before revising its Acid Rain regulations to conform to today's
revisions. In order to ensure that States have both sufficient
authority to issue Phase II permits and sufficient time to revise their
Acid Rain regulations, EPA will continue to accept State Acid Rain

[[Page 68351]]

rules that conform with the current part 72 until 2 years after the
date on which the final revisions are promulgated. Starting on the date
2 years after the promulgation of the final revisions, EPA expects all
State Acid Rain regulations to incorporate the revisions.
EPA notes that many States have not added to their Acid Rain rules
the provisions of part 74 (opt-in program) and part 76 (NOx compliance
plans and emissions limitations), which were issued relatively recently
in April 1995. Further, EPA has proposed additional part 76 provisions
setting Phase II NOx emissions limitations and expects to issue final
provisions by January 1, 1997. States may want to consider coordinating
adoption of the final revisions based on today's proposal with adoption
of the provisions of parts 74 and 76.

III. Part 72: Miscellaneous Permitting Matters

In addition to the revisions discussed above, EPA proposes a number
of revisions of sections of part 72 concerning matters such as
designated representatives, compliance plans, federal procedures for
permit issuance and revision, and confirmation reports on verified
savings from energy conservation and increased unit efficiency
measures. The primary purpose of these proposed changes is to
streamline the Acid Rain rules and reduce the administrative burden on
owners and operators of affected units.

A. Definitions

In addition to the definition revisions discussed elsewhere in this
notice, the Agency proposes the following revisions.
The definition of ``Acid Rain emissions limitation,'' for purposes
of sulfur dioxide emissions, is revised to make complete the list of
statutory provisions under which affected units may be allocated
allowances. Section 404(h), which is inadvertantly left out of the
current definition, is added. The definition of the term, for purposes
of nitrogen oxides emissions, is revised to remove references to
regulations implementing section 407 of the Act. The NOx Acid Rain
regulations in part 76 became final on May 23, 1995 and so the
definition is revised simply to cite part 76. Analogous changes are
made elsewhere in part 72 to replace general references to regulations
under section 407 by specific references to part 76 or sections of part
76.
The definition of ``coal-fired'' is revised to exclude the
superfluous reference to part 73 and to correct the reference to the
regulations implementing section 407 of the Act (i.e., part 76) to
reflect the fact that part 76 includes its own definition of ``coal-
fired.''
The definition of ``dispatch system'' is eliminated. In light of
the detailed provisions concerning dispatch system in section 72.33,
the definition is superfluous and potentially confusing.
The definition of ``permitting authority'' is revised to omit some
superfluous language and to reference part 70, rather than refering
generally to the regulations promulgated under title V. Such general
references in other provisions of part 72 are also changed to specific
references to parts 70 and 71 as appropriate.
The definition of ``submit or serve'' is revised in order to allow
documents, information, or correspondence to be provided to the
Administrator or any State permitting authority using any service of
the U.S. Postal Service or any equivalent means of dispatch and
delivery. The requirement in the current rule that such delivery be
accomplished using only certified mail or an equivalent service is
eliminated. Based on its experience in operating the Acid Rain Program,
EPA has found that the certified-mail requirement is not necessary and
may be burdensome on private parties.

B. Designated Representative

The current rule requires the selection of one designated
representative for each affected source and allows the selection of one
alternate designated representative per source. EPA has received
comment requesting that under certain limited circumstances a second
alternate designated representative be allowed. According to the
commenter, in general, the current rules give operating companies the
flexibility of having a designated representative at the upper
management level and an alternate who is closer to the plant operations
level in the company. Allegedly, this flexibility is in effect denied
to operating companies that are part of a holding company if the
holding company plans to use a NOx averaging plan under part 76 to
comply with the applicable Acid Rain NOx emission limitation.
Under Sec. 76.11, units that are subject to the standard NOx
emission limitations (in Secs. 76.5, 76.6, or 76.7), are under the
control of the same owner or operator, and have the same designated
representative may average their NOx emissions through a
compliance plan approved by the permitting authority. The detailed
requirements for determining whether units are in compliance with the
plan are set forth in Sec. 76.11. The commenter states that it is one
of several operating companies in a holding company and that all of the
operating companies intend to participate in a holding-company-wide
NOx averaging plan, which under Sec. 76.11 requires the selection
of a single designated representative for the entire holding company.
According to the commenter, that designated representative must, as a
practical matter, be someone at the holding-company management level.
Since each operating company can select only one alternate, each
operating company will be unable to have a designated representative or
alternate at both the management and the operations levels of the
operating company. Allegedly, this is important because each operating
company operates relatively independently, reflecting the fact that
each is in a different State and is subject to regulation by a
different utility regulatory authority.
In order to accomodate this limited circumstance where additional
flexibility may be needed, EPA proposes to allow the selection of a
second alternate designated representative in this circumstance. The
Agency requests comment on the need for this flexibility in this case.
The current rule also establishes procedures for the selection of a
designated representative and an alternate. Using these procedures, all
Phase I units and many Phase II units have selected designated
representatives. In addition, alternates were originally selected or
were added later in some cases, and some units have changed their
representatives. Based on this experience with the prescribed
procedures, EPA proposes to simplify the procedures and reduce the
burden they impose on owners and operators. The Agency maintains that
this can be done without negatively impacting the rights of minority or
other owners.
In particular, Secs. 72.20(c) and 72.24(a)(5) require that whenever
a designated representative or alternate is originally selected or
changed, notice must be provided daily for one week in a newspaper of
general circulation where the source is located or in a State
publication. The Agency has learned that this provision of newspaper
notice is often expensive and can be particularly cumbersome where a
single designated representative or alternate is selected or changed
for a group of units spread over a relatively wide geographic area
(e.g., a State) or where local newpapers are weekly rather than daily.
While some notice of designated-representative selection seems
desirable, EPA believes that the current rule is

[[Page 68352]]

unduly burdensome. EPA proposes to revise the rules to require only one
notice in the newspaper (i.e., notice for one day), rather than daily
notices for a week. Further, since the designated representative is the
primary person representing the owners and operators and is responsible
for all actions by any alternate, it seems unnecessary to require
notice of selection or change of an alternate.
EPA also proposes a minor correction of Sec. 72.25. That section
currently provides that the Administrator will rely on a certificate of
representation until a superseding one is ``submitted.'' 40 CFR
72.25(a). However, the Administrator will be unaware of any superseding
certificate until he or she receives it. Further, Sec. 72.20(b) states
that a certificate of representation is binding upon receipt of the
complete certificate by the Administrator. Section 72.25 is therefore
revised to provide that a certificate is relied on until ``receipt'' of
a superseding certificate.

C. Compliance Plans

l. Submission of Substitution and Reduced Utilization Plans
Sections 72.41 and 72.42 currently state that a new substitution
plan or reduced utilization plan may be submitted not later than 90
days before the allowance transfer deadline. A submission must be made
by both the Phase I unit and its prospective substitution or
compensating unit so that the plan will be reflected in their Acid Rain
permits. However, there are other provisions of the rules that affect
when such plans may be approved and take effect and that must be
considered in deciding when to submit a plan. An affected unit must, as
of the allowance transfer deadline, hold sufficient allowances to cover
its emissions for the prior year. Consequently, the status of a unit as
an affected unit for a given year (e.g., in Phase I, its status as a
substitution unit or a compensating unit) must be determined as of the
allowance transfer deadline. A new compliance plan designating a new
substitution or compensating unit for a Phase I unit must be approved
and active by the allowance transfer deadline in order to be effective
for the year to which the allowance transfer deadline applies.
A new plan may include both a Phase I unit and a prospective
substitution or compensating unit at a source that has no Phase I units
and so lacks a Phase I permit. Since each unit must have a Phase I
permit that includes the plan, the plan must be added to the Phase I
unit's existing permit and included in a new Phase I permit for the
source with the substitution or compensating unit. Because the Agency
has up to 6 months to act on a new permit, the Phase I unit's plan and
the source's new permit application that includes the plan should be
submitted at least 6 months before the allowance transfer deadline.
Later submission will not ensure approval of the plan in time for use
for the year to which that allowance transfer deadline applies.
If all the units in a new plan are at sources that already have
Phase I permits, then the plan can be added to both the Phase I unit's
permit and the prospective substitution or compensating unit's permit
through a permit revision. If the permit modification procedures are
used, the Agency still has up to 6 months to act. However, if the fast-
track amendment procedures are used, the Agency has 60 days from the
start of the public comment period to act. In the latter case, the
submission deadline of 90 days prior to the allowance transfer deadline
provides sufficient time for approval of the plan.18
---------------------------------------------------------------------------

\18\ Section 72.30(b)(3) references the deadlines in subpart D
of part 72 and part 76 for applying for compliance plans. The
provision is redundant and is therefore removed.
---------------------------------------------------------------------------

In order to ensure that designated representatives consider the
procedures and timing that must be followed in submitting new plans,
EPA proposes to revise Secs. 72.41(b)(3) and (c)(4). The revisions
state that new plans must be submitted no later than 6 months prior to
the allowance transfer deadline but that, if the fast-track amendment
procedures are available, submission must be no later than 90 days
before the allowance transfer deadline.
2. Repowering Extension Plans
The current Sec. 72.44 includes provisions concerning failed
repowering projects. The regulation requires that, if efforts to
complete and test the project are terminated prior to construction or
start-up testing, the designated representative must demonstrate to the
satisfaction of the Administrator that the efforts were in good faith.
Similarly, if the project is properly constructed and tested but is
unable to achieve emission reductions specified in the repowering
extension plan, a demonstration must be provided. Under the current
Sec. 72.81(a), determinations concerning failed projects must be
processed as permit modifications. However, the interaction between the
demonstration requirements in the current Sec. 72.44(g) and the
procedures in Sec. 72.81 is unclear, particularly when the State
permitting authority issued the permit containing the repowering
extension plan and is therefore handling the permit modifications.
EPA proposes to revise Sec. 72.44(g) to clarify the interaction of
the substantive and procedural requirements concerning failed projects.
Under the revisions, the designated representative submits to the
permitting authority a permit modification in which he or she makes the
necessary demonstrations. The Administrator determines whether the
demonstrations have been made. Where the State is the permitting
authority, the State acts on the permit modification consistent with
the Administrator's determination.

D. Federal Permit Issuance

1. The current Sec. 72.60(b) requires that the Administrator issue
or deny an Acid Rain permit within 6 months of receipt of a complete
permit application. However, Sec. 72.74(b) provides that initial Phase
II permits, for which applications are due by January 1, 1996, must be
issued by the statutory deadline of January 1, 1998 if they are issued
by the Administrator. EPA proposes to revise Sec. 72.60(b) to provide
that deadline in Sec. 72.74(b) applies, rather than the 6-month
deadline, to any initial Phase II permits issued by the Administrator.
2. The current Sec. 72.61 provides that a permit application is
deemed complete after 30 days in the absence of notification by the
Administrator that it is incomplete. When additional information is
requested by the Administrator, the designated representative has at
least 30 days to respond. EPA proposes to revise this section to make
it consistent with the currently different completeness provisions of
part 71 (and part 70) in order to avoid having two types of
completeness procedures. Under the revisions, automatic completeness
occurs after 60 days from receipt and additional information must be
submitted within a reasonable period specified by the Administrator. In
addition, language in parts 70 and 71 is added to this section
requiring designated representatives to provide supplementary
information when they become aware that relevant information was not
submitted or incorrect information was submitted.19
---------------------------------------------------------------------------

\19\ This language in parts 70 and 71 is also added to
Sec. 72.80 with regard to permit revisions.
---------------------------------------------------------------------------

3. As discussed above, EPA is proposing to revise the provisions
for Acid Rain permitting by States in order to allow, for certain types
of draft permits, service of notice on a list of persons and foregoing
of newspaper

[[Page 68353]]

notice. For the same reasons, EPA proposes a similar type of revision
for federal Acid Rain permitting. The Administrator may provide Federal
Register notice and notice for a list of persons and omit newspaper
notice where the only Acid Rain emissions limitations in the draft
permit are the requirements to hold sufficient allowances for SO2
or to comply with NOX emission limitations under Secs. 76.5, 76.6,
76.7, or 76.11.
Moreover, the list of persons required to be served notice of draft
and final permits under the current rule is different than the list of
persons required to be served under parts 70 and 71. This difference
complicates the notice process without any significant benefit. EPA
proposes to revise the list of persons for required service of
federally-processed draft and final permits to be consistent with parts
70 and 71.20 For example, parts 70 and 71 do not require service
on the State or local utility regulatory authorities with jurisdiction
over the unit involved or the owners of the unit. No utility regulatory
authorities commented on any of the Acid Rain permits or permit
revisions that have been issued by EPA for Phase I. The proposal
therefore eliminates such authorities from automatically-required
service.21 Any utility regulatory authorities that want to receive
notice of draft and final permits will still have the option of
requesting to be treated as an interested person and thereby receiving
notice.
---------------------------------------------------------------------------

\20\ The same change is proposed for the list of persons on
which requested fast-track amendments submitted to the Administrator
must be served under Sec. 72.82. Where requested fast-track
amendments are submitted to the State as the permitting authority,
the proposal provides that the list of persons is the same persons
on which the State permitting authority must serve notice of draft
permits under the State operating permits program. Further, since
parts 70 and 71 require service of notice on ``affected States'' and
include a definition of that term, today's proposal includes a new
definition that adopts the ``affected State'' definition in part 71.
\21\ The proposal therefore also eliminates the requirement to
identify such authorities in submissions to EPA (e.g., in a source's
certificate of representation).
---------------------------------------------------------------------------

E. Permit Revision

1. EPA proposes to make minor revisions to remove specific
reference to part 70 procedures from, and to add specific references to
Sec. 72.80 in, Sec. 72.81 concerning permit modifications.
2. EPA proposes to lengthen the deadline by which a State
permitting authority must act on a fast-track modification. Under the
current rule, the Administrator or State permitting authority must act
within 30 days of the close of the 30-day comment period. State
permitting authorities must handle many more permits covering a broader
range of types of sources and emission limitations than EPA's Acid Rain
Division, which handles only Acid Rain permits for the Administrator.
EPA is concerned that the 30-day deadline for States to act on a fast-
track modification may be unrealistic in light of their other,
significant responsibilities. To put the 30-day deadline in
perspective, States under title V can take up to 18 months to issue
permits or make significant permit modifications. Under today's
proposal, the 30-day deadline will continue to apply to the
Administrator but a 90-day deadline from the end of the comment period
will apply to State permitting authorities.
3. EPA proposes to remove and replace certain confusing language at
the end of the fast-track modification provisions concerning review by
the Administrator and affected States. The current language makes fast-
track modifications subject to the same review as significant permit
amendments. The proposal states this more directly. Such review is
appropriate since fast-track modifications can involve important
changes to a permit.
4. The current rule concerning administrative permit amendments
relies heavily on, and cites, the part 70 administrative permit
amendment procedures. These part 70 procedures are currently the
subject of an on-going rulemaking in which extensive revisions have
been proposed. See 59 FR 44475-79. EPA proposes to remove the citations
to part 70 and to set forth in Sec. 72.83 itself the procedures for
administrative amendments to Acid Rain permits. EPA believes that the
administrative amendment procedures currently applicable to Acid Rain
permits are simple and, except as discussed below, should not be
substantively changed.
While the proposal continues to require action by the permitting
authority within 60 days of receipt, the period for acting on one
potentially very complicated administrative amendment, i.e., the
addition of an alternative emissions limitation demonstration period
for NOX, is lengthened to 90 days. Before implementing the
addition of an alternative emissions limitation demonstration period, a
permitting authority must determine whether the requirements of
Sec. 76.10 have been met. The designated representative must provide
extensive information, e.g., showing that the unit has a properly
installed and operated NOX emission control system designed to
meet the standard NOX emission limitation (under Secs. 76.5, 76.6,
or 76.7), describing why the unit cannot meet the standard emission
limitation, and outlining the testing and procedures to be undertaken
to determine the maximum emission reduction that can be achieved with
the installed system. EPA maintains that 60 days will likely be
insufficient time, particularly for State permitting authorities, to
evaluate this information and, if the requirements of Sec. 76.10 are
met, grant a requested alternative emissions limitation demonstration
period and that 90 days is a more reasonable deadline.
The proposal also adds a provision explicitly allowing the
permitting authority to make administrative permit amendments (other
than the addition of an alternative emission limitation demonstration
period) on its own motion. This procedure may be used to correct minor
errors in a permit that come to the attention of the permitting
authority.
Also added to Sec. 72.83 are provisions in the current part 70 that
allow immediate implementation of administrative permit amendments that
meet applicable requirements and that eliminate review of such
amendments by the Administrator or affected States. This adds directly
to part 72 provisions that the current Sec. 72.83 makes applicable by
reference to part 70.
5. The current rule concerning permit reopenings relies heavily on,
and cites, part 70 reopening procedures. EPA proposes to eliminate the
references and set forth in Sec. 72.85 the full procedures. Consistent
with the current part 70 provisions, the proposal states that reopening
for cause may occur when: Additional Acid Rain requirements become
applicable; there is a material mistake in the permit; inaccurate
statements were made in establishing a permit term or condition; or a
permit revision is necessary to assure compliance with the Acid Rain
Program.

F. Reduced Utilization Accounting

Under the current rule, Phase I units must account for any
underutilization. A few revisions are proposed with regard to this
accounting.
1. The current rule allows a designated representative to submit an
identification of dispatch system in order to change a unit's dispatch
system from what is listed in the NADB, which indicates the operator of
each unit. A dispatch-system identification must be submitted by
January 30 of the first year for which the new dispatch system is to
take effect. Traditionally, there have been relatively few changes in
the operator and the dispatching of utility

[[Page 68354]]

units. However, in light of increased competition in the electric
industry and the potential of future restructuring of the industry, the
Agency is concerned that changes in owners and operators and in
dispatching of units may occur more frequently and at times that make
it impossible to meet the January 30 deadline. EPA therefore proposes
to give the Administrator the discretion to grant exemptions from that
deadline in order to allow late submissions.
2. The current rule sets forth procedures for claiming kilowatt
hour savings from energy conservation measures or heat rate reductions
from improved unit efficiency measures and using the resulting heat
input reductions to reduce the surrender of allowances to account for
reduced utilization of Phase I units. In the annual compliance
certification reports submitted by March 1, a designated representative
may include estimated savings from energy conservation or estimated
heat rate reductions from improved unit efficiency measures for the
prior year. If any such estimates are included in the annual compliance
certification report, the designated representative must submit a
confirmation report by July 1 that provides and supports the verified
amounts.
The current language in Sec. 72.91(b)(1)(iii) concerning the
methods for supporting the verified amounts of kilowatt hour savings,
heat rate improvement, and resulting heat input reductions needs some
clarification.22 The purpose of the provision is to provide two
alternative approaches to verification: documentation that may follow
the EPA Conservation Verification Protocol; or certification by the
appropriate State utility regulatory authority. The current provision
could be read to require that only one of these approaches be used for
all estimated savings and heat input reductions so that, for example,
if certification is to be used, it must be used for all the estimates.
EPA proposes to revise the provision to make it clear that there is
flexibility to use documentation with regard to improved unit
efficiency measures or some energy conservation measures and to use
certification for other measures.
---------------------------------------------------------------------------

\22\ The verification process, found in Sec. 72.91(b), is
incorrectly cross-referenced in Sec. 72.43(b)(2)(iii)(B) of the
current rule. Today's proposal corrects the reference. In addition,
certain typographical errors in Sec. 72.91(b) (e.g., incomplete
reference to ``improved unit efficiency measures'') are corrected.
---------------------------------------------------------------------------

3. The current regulatory provisions concerning heat input
reductions due to measures that reduce a unit's heat rate need
clarification and revision. A measure that reduces a unit's heat rate
may be treated as a supply-side energy conservation measure by another
unit or as an improved unit efficiency measure by the unit at which the
measure is implemented. Over a given period of time, a number of
specific measures may be implemented at a unit to reduce its heat rate.
However, these measures may be offset by reductions in generation
efficiency at the same unit resulting from other factors, e.g., from
the aging or changed operations of the unit. In that case, even though
each measure may, in itself, reduce the heat rate of the unit below
what the heat rate would otherwise have been, the net effect of all the
measures on the unit's heat rate will be less than the sum of the
reductions attributed to each measure.
It is the net effect of these measures on the unit's heat rate that
should be treated as accounting for reduced utilization. Consequently,
EPA proposes to add a provision that puts a ceiling on the total heat
input reductions that may be claimed for all measures that reduce a
given unit's heat rate, whether the measures are treated as energy
conservation or improved unit efficiency measures. Under the proposal,
the total verified heat input reductions attributed to such measures
may not exceed the difference between the kilowatt hour generation
attributed to the unit for the calendar year times the difference
between the unit's heat rate for 1987 and its heat rate for the
calendar year. This ensures that heat input reductions cannot exceed
the heat input reductions attributable to net heat rate improvement
since the end of the base period (i.e., 1985-1987). Heat rate
improvements made up through 1987 are already reflected in the baseline
utilization and so cannot be used to account for underutilization of a
unit since the base period. See 58 FR 60950, 60961 (November 18, 1993).
In light of this ceiling on heat input reductions claimed for
energy conservation measures improving generation efficiency (as well
as for improved unit efficiency measures), EPA sees no need to burden
State utility regulatory authorities with the verification of claimed
reductions from this limited category of energy conservation measures.
EPA will instead review the verification presented by designated
representatives and will compare the claimed heat input reductions to
the ceiling. Consequently, EPA proposes to remove the option of
verification by State utility regulatory authorities of claimed
reductions from energy conservation measures improving generation
efficiency.
4. The current rule provides that, if the total verified amount of
heat input reductions in the confirmation report differs from the total
estimated amount in the annual compliance certification report, the
confirmation report must calculate the number of allowances, if any, to
be surrendered or returned as a result. EPA maintains that the
provision concerning calculation of allowances to be returned needs
clarification and revision.
a. Under the current rule, if the total verified heat input
reductions exceed the total estimated heat input reductions, returned
allowances are to be calculated using a specified formula in
Sec. 72.91(b)(4) based on the difference between the verified and
estimated amounts. Section 72.91(a)(7) sets a limit on the total amount
of ``plan reductions'' (i.e., offsets to underutilization that are
attributed to energy conservation, improved unit efficiency, sulfur-
free generation, and compensating units). A Phase I unit's plan
reductions minus any compensating generation that it provides as a
compensating unit cannot exceed the Phase I unit's baseline minus its
actual utilization. The purpose of this limitation is ``to prevent plan
reductions from one Phase I unit from being used to offset the
underutilization of another Phase I unit that has no reduced
utilization plan.'' 58 FR 60962. This purpose applies equally whether
the plan reductions involved reflect estimated offsets from
conservation and improved unit efficiency or verified offsets. The
confirmation process simply replaces estimated with verified offset
amounts and corrects for any differences; it is not intended to allow
greater offsets than if the verified offset amounts had been available
when the annual compliance certification report was submitted.
The simplest way to ensure that designated representatives
understand that this limitation applies is to limit the number of
allowances that are to be returned to the total number of allowances
that were deducted from the unit's Allowance Tracking System account
for underutilization based on the annual compliance certification
report. EPA proposes to add language (in Sec. 72.91(b)(4)(iv)) setting
forth this limitation. To the extent allowances were deducted based on
the annual certification report, then those allowances represented
underutilization of the unit (i.e., a positive difference between the
unit's baseline and its actual utilization after accounting for all
offsets). If allowances in excess of the amount of that allowance
deduction were returned, then verified offsets from

[[Page 68355]]

conservation or improved unit efficiency would be used, in effect, to
offset some other unit's underutilization.
b. Under the current rule, if the total verified offsets are less
than the total estimated offsets, surrendered allowances are to be
calculated using the absolute value of the formula specified for
returning allowances in Sec. 72.91(b)(4). EPA has found that this
provision concerning the allowances to be surrendered is not correct in
all cases and should be revised.
Under Secs. 72.91 and 72.92, allowance surrender is determined
initially on a dispatch-system-wide basis so that underutilization of
one Phase I unit in the dispatch system may be offset by
overutilization of another Phase I unit in that dispatch system. Once
it is determined that allowances must be surrendered for the dispatch
system, each Phase I unit's share of the surrender is calculated. The
approach in the current rule is accurate if the Phase I unit had to
surrender allowances based on the annual compliance certification
report. In that case, the unit's underutilization was not offset
completely by other Phase I units and any overstatement of offsets in
the estimates used in the annual compliance certification report must
result in additional surrender of allowances by the unit.
In contrast, if the Phase I unit did not have to surrender
allowances based on the annual compliance certification report, the
overstatement of offsets in the estimates could be offset by
overutilization of other Phase I units. The provisions of the current
Sec. 72.91(b)(5) do not take account of that possibility.
EPA proposes to revise Sec. 72.91(b)(5) to correct this problem and
ensure that the confirmation process does not result in the surrender
of more allowances than if the verified amounts for conservation or
improved unit efficiency offsets had been available when the annual
compliance certification report was submitted. The revision provides
that each Phase I unit that used estimated conservation or improved
unit efficiency offsets must recalculate its adjusted utilization using
the verified amounts and then that the allowance surrender formula in
Sec. 72.92(c) must be reapplied using the recalculated adjusted
utilizations. To the extent this results in greater allowance surrender
than the surrender based on the annual compliance certification report,
the difference must be surrendered.
c. Under the current rule, the designated representative must
include in the confirmation report calculations of any change in the
excess emissions that were previously determined based on the annual
compliance certification report. EPA has de
