Idaho facility shall take the following measures to reduce PM-10 
emissions from mini-flushes and to ensure there is no bias toward 
conducting mini-flushes during night-time hours.
    (A) Mini-flushes shall be limited to no more than 50 minutes per day 
(based on a monthly average) beginning January 1, 1999. Failure to meet 
this limit for any given calendar month will be construed as a separate 
violation for each day during that month that mini-flushes lasted more 
than 50 minutes. The monthly average for any calendar month shall be 
calculated by summing the duration (in actual minutes) of each mini-
flush during that month and

[[Page 727]]

dividing by the number of days in that month.
    (B)(1) No mini-flush shall be conducted at any time unless one of 
the following operating parameters is satisfied:
    (i) The flow rate of recirculated phossy water is equal to or less 
than 1800 gallons per minute; or
    (ii) The secondary condenser outlet temperature is equal to or 
greater than 36 degrees Centigrade.
    (2) The prohibition set forth in paragraph (c)(5)(ii)(B)(1) of this 
section shall not apply during periods of malfunction or emergency, 
provided the owner or operator of the Astaris-Idaho facility complies 
with the requirements of paragraph (c)(9) of this section.
    (6) At all times, including periods of startup, shutdown, 
malfunction, or emergency, the owner or operator of the Astaris-Idaho 
facility shall, to the extent practicable, maintain and operate each 
source of PM-10 at the Astaris-Idaho facility, including without 
limitation those sources identified in Column II of Table 1 to this 
section and associated air pollution control equipment, in a manner 
consistent with good air pollution control practices for minimizing 
emissions. Determination of whether acceptable operating and maintenance 
procedures are being used will be based on information available to the 
Regional Administrator which may include, but is not limited to, 
monitoring results, opacity observations, review of operating and 
maintenance procedures, and inspection of the source.
    (7) Maintaining operation of a source within approved parameter 
ranges, promptly taking corrective action, and otherwise following the 
work practice, monitoring, record keeping, and reporting requirements of 
this section do not relieve the owner or operator of the Astaris-Idaho 
facility from the obligation to comply with applicable emission 
limitations and work practice requirements at all times.
    (8) An affirmative defense to a penalty action brought for emissions 
in excess of an emission limitation shall be available if the excess 
emissions were due to startup or shutdown and all of the following 
conditions are met:
    (i) The owner or operator of the Astaris-Idaho facility notifies EPA 
and the Tribes in writing of any startup or shutdown that is expected to 
cause excess emissions. The notification shall be given as soon as 
possible, but no later than 48 hours prior to the start of the startup 
or shutdown, unless the owner or operator demonstrates to EPA's 
satisfaction that a shorter advanced notice was necessary. The notice 
shall identify the expected date, time, and duration of the excess 
emissions event, the source involved in the excess emissions event, and 
the type of excess emissions event.
    (ii) The periods of excess emissions that occurred during startup or 
shutdown were short and infrequent and could not have been prevented 
through careful planning and design.
    (iii) The excess emissions were not part of a recurring pattern 
indicative of inadequate design, operation, or maintenance.
    (iv) If the excess emissions were caused by a bypass (an intentional 
diversion of control equipment), then the bypass was unavoidable to 
prevent loss of life, personal injury, or severe property damage.
    (v) At all times, the facility was operated in a manner consistent 
with good practice for minimizing emissions.
    (vi) The frequency and duration of operation in startup or shutdown 
mode was minimized to the maximum extent practicable.
    (vii) All possible steps were taken to minimize the impact of the 
excess emissions on ambient air quality.
    (viii) All emission monitoring systems were kept in operation if at 
all possible.
    (ix) The owner or operator's actions during the period of excess 
emissions were documented by properly signed, contemporaneous operating 
logs, or other relevant evidence.

notice of the startup or shutdown to EPA and the Tribes within 48 hours 
of the time when emission limitations were exceeded due to startup or 
shutdown. This notice fulfills the requirement of paragraph (g)(5) of 
this section. This notice must contain a description of

[[Page 728]]

the startup or shutdown, any steps taken to mitigate emissions, and 
corrective actions taken.
    (xi) No exceedance of the 24-hour PM-10 National Ambient Air Quality 
Standard, 40 CFR 50.6(a) was recorded on any monitor located within the 
Fort Hall PM-10 nonattainment area that regularly reports information to 
the Aerometric Information Retrieval System-Air Quality Subsystem, as 
defined under 40 CFR 58.1(p), on any day for which the defense of 
startup or shutdown is asserted.
    (xii) In any enforcement proceeding, the owner or operator of the 
Astaris-Idaho facility has the burden of proof on all requirements of 
this paragraph (c)(8).
    (9) An affirmative defense to a penalty action brought for emissions 
in excess of an emission limitation shall be available if the excess 
emissions were due to an emergency or malfunction and all of the 
following conditions are met:
    (i) The excess emissions were caused by a sudden, unavoidable 
breakdown of technology, beyond the control of the owner or operator of 
the Astaris-Idaho facility.
    (ii) The excess emissions;
    (A) Did not stem from any activity or event that could have been 
foreseen and avoided or planned for; and
    (B) Could not have been avoided by better operation and maintenance 
practices.
    (iii) To the maximum extent practicable the air pollution control 
equipment or processes were maintained and operated in a manner 
consistent with good practice for minimizing emissions.
    (iv) Repairs were made in an expeditious fashion when the operator 
knew or should have known that applicable emission limitations were 
being exceeded. Off-shift labor and overtime must have been utilized, to 
the extent practicable, to ensure that such repairs were made as 
expeditiously as practicable.
    (v) The amount and duration of the excess emissions (including any 
bypass) were minimized to the maximum extent practicable during periods 
of such emissions.
    (vi) All possible steps were taken to minimize the impact of the 
excess emissions on ambient air quality.
    (vii) All emission monitoring systems were kept in operation if at 
all possible.
    (viii) The owner or operator's actions in response to the excess 
emissions were documented by properly signed, contemporaneous operating 
logs, or other relevant evidence.
    (ix) The excess emissions were not part of a recurring pattern 
indicative of inadequate design, operation, or maintenance.
    (x) The owner or operator of the Astaris-Idaho facility submitted 
notice of the emergency or malfunction to EPA and the Tribes within 48 
hours of the time when emission limitations were exceeded due to the 
emergency or malfunction. This notice fulfills the requirement of 
paragraph (g)(5) of this section. This notice must contain a description 
of the emergency or malfunction, any steps taken to mitigate emissions, 
and corrective actions taken.
    (xi) No exceedance of the 24-hour PM-10 National Ambient Air Quality 
Standard, 40 CFR 50.6(a), was recorded on any monitor located within the 
Fort Hall PM-10 nonattainment area that regularly reports information to 
the Aerometric Information Retrieval System-Air Quality Subsystem, as 
defined under 40 CFR 58.1(p), on any day for which the defense of 
emergency or malfunction is asserted.
    (xii) In any enforcement proceeding, the owner or operator of the 
Astaris-Idaho facility has the burden of proof on all requirements of 
this paragraph (c)(9).
    (10) For each source identified in Column II of Table 2 to this 
section, the owner or operator of the Astaris-Idaho facility shall take 
appropriate actions to reduce visible emissions from the source if 
opacity exceeds the opacity action level for that source identified in 
Column III of Table 2 of this section. Such actions shall be commenced 
as soon as possible but not to exceed 24 hours after an exceedance of 
the opacity action level is first identified and shall be completed as 
soon as possible. Such actions shall include, but not be limited to, 
those actions identified in

[[Page 729]]

the O&M plan for the source. Exceedance of an opacity action level does 
not constitute a violation of this section, but failure to take 
appropriate corrective action as identified in this paragraph (c)(10) 
does constitute a violation of this section.
    (11) The owner or operator of the Astaris-Idaho facility shall 
notify EPA prior to the construction of a new source of PM-10 at the 
Astaris-Idaho facility or the modification of an existing source at the

    (B) An estimate of potential PM-10 emissions from the source on both 
a 24-hour and annual basis, without consideration of any proposed air 
pollution control equipment;
    (C) The expected daily hours of operation of the source, including 
any seasonal variation, and an estimate of actual PM-10 emissions from 
the source on both a 24-hour and annual basis, considering the effect of 
any proposed air pollution control equipment; and
    (D) A description of any PM-10 control technology to be implemented 
at the source along with an analysis of alternative control technologies 
considered but rejected.
    (iii) Any source identified in this section shall continue to be 
subject to the requirements of this section notwithstanding the 
modification of the source.
    (iv) The requirements of this paragraph (c)(11) are in addition to 
any other requirements to obtain a permit under the Clean Air Act.
    (v) This paragraph (c)(11) shall cease to apply if either of the 
following events occur:
    (A) EPA promulgates a minor new source review program for PM-10 that 
applies to the Astaris-Idaho facility; or
    (B) The Tribes promulgate a minor new source review program for PM-
10 that applies to the Astaris-Idaho facility and EPA approves the 
Tribes' program under of this part.
    (vi) If, after receipt of the notice referred to in this paragraph 
(c)(11), EPA notifies Astaris-Idaho in writing that a 90 day delay in 
the commencement of construction or modification is not required, 
Astaris-Idaho may proceed with the commencement of the construction or 
modification as described in the notice, subject to the other 
requirements of this section.
    (d) Reference test methods. (1) For each source identified in Column 
II of Table 1 to this section, the reference test method for the 
corresponding emission limitation in Column III of Table 1 to this 
section for that source is identified in Column IV of Table 1 to this 
section. For each source identified in Column II of Table 2 to this 
section, the reference test method for the corresponding opacity action 
level in Column III of Table 2 to this section for that source is 
identified in Column IV of Table 2 to this section.
    (2) When Method 201/201A or Methods 201/201A and 202 of 40 CFR Part 
60, appendix A, are specified as the reference test methods, the testing 
shall be conducted in accordance with the identified test methods and 
the following additional requirements:
    (i) Each test shall consist of three runs, with each run a minimum 
of one hour.
    (ii) Method 202 shall be run concurrently with Method 201 or Method 
201A. Unless Method 202 is specifically designated as part of the 
reference test method, Method 202 shall be performed on each source for 
informational purposes only and the results from the Method 202 test 
shall not be included in determining compliance with the mass emission 
limit for the source.
    (iii) The source shall be operated at a capacity of at least 90% of 
maximum during all tests unless the Regional Administrator determines in 
writing that other operating conditions are representative of normal 
operations.
    (iv) Only regular operating staff may adjust the processes or 
emission control device parameters during a performance test or within 
two hours prior to the tests. Any operating adjustments made during a 
performance

[[Page 730]]

test, which are a result of consultation during the tests with source 
testing personnel, equipment vendors, or other consultants may render 
the source test invalid.
    (v) For all reference tests, the sampling site and minimum number of 
sampling points shall be selected according to EPA Method 1 (40 CFR part 
60, appendix A).
    (vi) EPA Methods 2, 2C, 2D, 3, 3A, and 4 (40 CFR part 60, appendix 
A) shall be used, as appropriate, for determining mass emission rates.
    (vii) The mass emission rate of PM-10 shall be determined as 
follows:
    (A)(1) Where Method 201/201A is identified as the reference test 
method, the mass emission rate of PM-10 shall be determined by taking 
the results of the Method 201/201A test and then multiplying by the 
average hourly volumetric flow rate for the run.
    (2) Where Methods 201/201A and 202 are identified as the reference 
test methods, the mass emission rate of PM-10 shall be determined by 
first adding the PM-10 concentrations from Methods 201/201A and 202, and 
then multiplying by the average hourly volumetric flow rate for the run.
    (B) The average of the three required runs shall be compared to the 
emission standard for purposes of determining compliance.
    (viii) Two of the three runs from a source test of each Medusa-
Andersen stack on the furnace building (Table 1 of this section, sources 
18d, 18e, 18f, and 18g) shall include at least 20 minutes of slag 
tapping and a third run shall include at least 20 minutes of metal 
tapping.
    (ix) At least one of the three runs from a source test of the excess 
CO burner (Table 1 of this section, source 26b) shall be conducted 
during either a mini-flush or hot-flush that lasts for at least 30 
minutes.
    (3) Method 5 shall be used in place of Method 201 or 201A for the 
calciner scrubbers (Table 1 of this section, source 9a) and any other 
sources with entrained water drops. In such case, all the particulate 
matter measured by Method 5 must be counted as PM-10, and the testing 
shall be conducted in accordance with paragraph (d)(2) of this section.
    (4) Method 5 may be used as an alternative to Method 201 or 201A for 
a particular point source, provided that all of the particulate measured 
by Method 5 is counted as PM-10 and the testing is conducted in 
accordance with paragraph (d)(2) of this section.
    (5)(i) An alternative reference test method or a deviation from a 
reference test method identified in this section may be approved as 
follows:
    (A) The owner or operator of the Astaris-Idaho facility must submit 
a written request to the Regional Administrator at least 60 days before 
the performance test is scheduled to begin which includes the reasons 
why the alternative or deviation is needed and the rationale and data to 
demonstrate that the alternative test method or deviation from the 
reference test method:
    (1) Provides equal or improved accuracy and precision as compared to 
the specified reference test method; and
    (2) Does not decrease the stringency of the standard as compared to 
the specified reference test method.
    (B) If requested by EPA, the demonstration referred to in paragraph 
(d)(5)(i)(A) of this section must use Method 301 in 40 CFR part 63, 
appendix A to validate the alternative test method or deviation.
    (C) The Regional Administrator must approve the request in writing.
    (ii) Until the Regional Administrator has given written approval to 
use an alternative test method or to deviate from the reference test 
method, the owner or operator of the Astaris-Idaho facility is required 
to use the reference test method when conducting a performance test 
pursuant to paragraph (e)(1) of this section.
    (6) For the purpose of submitting compliance certifications or 
establishing whether or not a person has violated or is in violation of 
any requirement of this section, nothing in this section shall preclude 
the use, including the exclusive use, of any credible evidence or 
information relevant to whether a source would have been in compliance 
with applicable requirements if the appropriate performance or reference 
test or procedure had been performed.
    (e) Monitoring and additional work practice requirements. (1) The 
owner or

[[Page 731]]

operator of the Astaris-Idaho facility shall conduct a performance test 
to measure PM-10 emissions as follows:

(e)(9), the owner or operator of the Astaris-Idaho facility may conduct 
a visible emission observation of any source subject to the requirements 
of this paragraph (e)(9) using the reference test method for the opacity 
limit, in which case corrective action must be taken only if opacity 
exceeds the opacity action level.
    (iii) Should, for good cause, the visible emissions reading not be 
conducted on schedule, the owner or operator of the Astaris-Idaho 
facility shall record the reason observations were not conducted. 
Visible emissions observations shall be conducted immediately upon the 
return of conditions suitable for visible emissions observations.
    (iv) If, after conducting weekly visible emissions observations for 
a given source for more than one year and detecting no visible emissions 
from that source for 52 consecutive weeks, the frequency of observations 
may be reduced to monthly. The frequency of observations for such source 
shall revert to weekly if visible emissions are detected from that 
source during any monthly observation or at any other time.
    (v) With respect to slag handling (Table 1 of this section, source 
8a):
    (A) Visible emission observations shall be made of the slag tapping 
area as viewed from the exterior of the furnace building and in the 
general area of the old slag pits;
    (B) For the first three months after the effective date of the 
opacity limit, the owner or operator of the Astaris-Idaho facility shall 
conduct a visual observation of this source three days each week and 
shall submit the results of such observations at the end of the three 
month time frame. Thereafter, such observations shall be conducted 
weekly or as otherwise provided in this paragraph (e)(9).
    (10) Except for, as applicable, monitoring malfunctions, associated 
repairs, and required quality assurance or control activities

adjustments), the owner or operator of the Astaris-Idaho facility shall 
conduct all monitoring with the monitoring devices required by 
paragraphs (e)(2), (e)(3), (e)(4), (e)(5), (e)(6), and (e)(7) of this 
section in continuous operation at all times that the monitored process 
is in operation. Data recorded during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
shall not be used for purposes of this section, including data averages 
and calculations, or fulfilling a minimum data availability requirement. 
The owner or operator of the Astaris-Idaho facility shall use data 
collected during

[[Page 738]]
