Ariz. Admin. Code § R18-2-715.01 - Standards of Performance for Existing Primary Copper Smelters; Compliance and Monitoring
A. The
cumulative occurrence and emission limits in
R18-2-715(F)
apply to the total of sulfur dioxide emissions from the smelter processing
units and sulfur dioxide control and removal equipment, but not uncaptured
fugitive emissions or emissions due solely to the use of fuel for space heating
or steam generation.
B. The owner
or operator shall include periods of malfunction, startup, shutdown or other
upset conditions when determining compliance with the cumulative occurrence or
annual average emission limits in
R18-2-715(F),
(G), or (H).
C. The owner or operator shall determine
compliance with the cumulative occurrence and emission limits contained in
R18-2-715(F) as
follows:
1. The owner or operator shall
calculate annual average emissions at the end of each day by averaging the
emissions for all hours measured during the compliance period defined in
subsection (J) ending on that day. An annual emissions average in excess of the
allowable annual average emission limit is a violation of
R18-2-715(F) if
either:
a. The annual average is greater than
the annual average computed for the preceding day; or
b. The annual averages computed for the five
preceding days all exceed the allowable annual average emission
limit.
2. The owner or
operator shall calculate a three-hour emissions average at the end of each
clock hour by averaging the hourly emissions for the preceding three
consecutive hours provided each hour was measured according to the requirements
in subsection (K).
D.
For purposes of this Section, the compliance date, unless otherwise provided in
a consent decree or a delayed compliance order, shall be January 14, 1986,
except that:
1. The compliance date for the
cumulative occurrence and emissions limits in
R18-2-715(F)(1)
and R18-2-715(G) is
January 15, 2002, and
2. The
compliance date for the cumulative occurrence and emissions limits in
R18-2-715(F)(2), (F)(3),
(G), and (H) is the effective date of this
rule.
E. For purposes of
subsection (C), a three-hour emissions average in excess of an emission level E
violates the associated cumulative occurrence limit n listed in
R18-2-715(F) if:
1. The number of all three-hour emissions
averages calculated during the compliance period in excess of that emission
level exceeds the cumulative occurrence limit associated with the emission
level; and
2. The average is
calculated during the last operating day of the compliance period being
reported.
F. A
three-hour emissions average only violates the cumulative occurrence limit n of
an emission level E on the day containing the last hour in the
average.
G. Multiple violations of
the same cumulative occurrence limit on the same day and violations of
different cumulative occurrence limits on the same day constitute a single
violation of
R18-2-715(F).
H. The violation of any cumulative occurrence
limit and an annual average emission limit on the same day constitutes only a
single violation of the requirements of
R18-2-715(F).
I. Multiple violations of a cumulative
occurrence limit by different three-hour emissions averages containing any
common hour constitutes a single violation of
R18-2-715(F).
J. To determine compliance with subsections
(C) through (I), the compliance period consists of the 365 calendar days
immediately preceding the end of each day of the month being reported unless
that period includes less than 300 operating days, in which case the number of
days preceding the last day of the compliance period shall be increased until
the compliance period contains 300 operating days. For purposes of this
Section, an operating day is any day on which sulfur-containing feed is
introduced into the smelting process.
K. To determine compliance with
R18-2-715(F) or
(H), the owner or operator of any smelter
subject to
R18-2-715(F) or
(H) shall install, calibrate, maintain, and
operate a measurement system for continuously monitoring sulfur dioxide
concentrations and stack gas volumetric flow rates in each stack that could
emit five percent or more of the allowable annual average sulfur dioxide
emissions from the smelter.
1. The owner or
operator shall continuously monitor sulfur dioxide concentrations and stack gas
volumetric flow rates in the outlet of each piece of sulfur dioxide control
equipment.
2. The owner or operator
shall continuously monitor captured fugitive emissions for sulfur dioxide
concentrations and stack gas volumetric flow rates and include these emissions
as part of total plant emissions when determining compliance with the
cumulative occurrence and emission limits in
R18-2-715(F) and
(H).
3. If the owner or operator demonstrates to
the Director that measurement of stack gas volumetric flow in the outlet of any
particular piece of sulfur dioxide control equipment would yield inaccurate
results once operational or would be technologically infeasible, then the
Director may allow measurement of the flow rate at an alternative sampling
point.
4. For purposes of this
subsection, continuous monitoring means the taking and recording of at least
one measurement of sulfur dioxide concentration and stack gas flow rate reading
from the effluent of each affected stack, outlet, or other approved measurement
location in each 15-minute period. Fifteen-minute periods start at the
beginning of each clock hour, and run consecutively. An hour of smelter
emissions is considered continuously monitored if the emissions from all
monitored stacks, outlets, or other approved measurement locations are measured
for at least 45 minutes of any hour according to the requirements of this
subsection.
5. The owner or
operator shall demonstrate that the continuous monitoring system meets all of
the following requirements:
a. The sulfur
dioxide continuous emission monitoring system installed and operated under this
Section meets the requirements of 40 CFR 60, Appendix B, Performance
Specification 6.
b. The sulfur
dioxide continuous emission monitoring system installed and operated under this
Section meets the quality assurance requirements of 40 CFR 60, Appendix
F.
c. The owner or operator shall
notify the Director in writing at least 30 days in advance of the start of
relative accuracy test audit (RATA) procedures performed on the continuous
monitoring system.
d. The Director
shall approve the location of all sampling points for monitoring sulfur dioxide
concentrations and stack gas volumetric flow rates in writing before
installation and operation of measurement instruments.
e. The measurement system installed and used
under this subsection is subject to the manufacturer's recommended zero
adjustment and calibration procedures at least once per 24-hour operating
period unless the manufacturer specifies or recommends calibration at shorter
intervals, in which case specifications or recommendations shall be followed.
The owner or operator shall make available a record of these procedures that
clearly shows instrument readings before and after zero adjustment and
calibration.
L. The owner or operator of a smelter subject
to this Section shall measure at least 95 percent of the hours during which
emissions occurred in any month.
M.
Failure of the owner or operator of a smelter subject to this Section to
measure any 12 consecutive hours of emissions according to the requirements of
subsection (K) or (S) is a violation of this Section.
N. The owner or operator of any smelter
subject to this Section shall maintain on hand and ready for immediate
installation sufficient spare parts or duplicate systems for the continuous
monitoring equipment required by this Section to allow for the replacement
within six hours of any monitoring equipment part that fails or malfunctions
during operation.
O. To determine
total overall emissions, the owner or operator of any smelter subject to this
Section shall perform material balances for sulfur according to the procedures
prescribed by Appendix 8 of this Chapter.
P. The owner or operator of any smelter
subject to this Section shall maintain a record of all average hourly emissions
measurements and all calculated average monthly emissions required by this
Section. The record of the emissions shall be retained for at least five years
following the date of measurement or calculation. The owner or operator shall
record the measurement or calculation results as pounds per hour of sulfur
dioxide. The owner or operator shall summarize the following data monthly and
submit the summary to the Director within 20 days after the end of each month:
1. For all periods described in subsection
(C) and (R), the annual average emissions as calculated at the end of each day
of the month;
2. The total number
of hourly periods during the month in which measurements were not taken and the
reason for loss of measurement for each period;
3. The number of three-hour emissions
averages that exceeded each of the applicable emissions levels listed in
R18-2-715(F) and
(G) for the compliance periods ending on each
day of the month being reported;
4.
The date on which a cumulative occurrence limit listed in
R18-2-715(F) or
(G) was exceeded if the exceedance occurred
during the month being reported; and
5. For all periods described in subsection
(T) and (U), the annual average emissions as calculated at the end of the last
day of each month.
Q. An
owner or operator shall install instrumentation to monitor each point in the
smelter facility where a means exists to bypass the sulfur removal equipment,
to detect and record all periods that the bypass is in operation. An owner or
operator of a copper smelter shall report to the Director, not later than the
15th day of each month, the recorded information required by this Section,
including an explanation for the necessity of the use of the bypass.
R. The owner or operator shall determine
compliance with the cumulative occurrence and fugitive emission limits
contained in
R18-2-715(G) as
follows:
1. The owner or operator shall
calculate annual average emissions at the end of each day by averaging the
emissions for all hours measured during the compliance period, as defined in
subsection (R)(8), ending on that day. An annual emissions average in excess of
the allowable annual average emission limit is a violation of
R18-2-715(G) if
either:
a. The annual average is greater than
the annual average computed for the preceding day; or
b. The annual averages computed for the five
preceding days all exceed the allowable annual average emission
limit.
2. The owner or
operator shall calculate a three-hour emissions average at the end of each
clock hour by averaging the hourly emissions for the preceding three
consecutive hours provided each hour was measured according to the requirements
contained in subsection (S).
3. For
purposes of subsection (R)(2), a three-hour emissions average in excess of an
emission level Ef violates the associated cumulative
occurrence limit n listed in
R18-2-715(G) if:
a. The number of all three-hour emissions
averages calculated during the compliance period in excess of that emission
level exceeds the cumulative occurrence limit associated with the emission
level; and
b. The average is
calculated during the last operating day of the compliance period being
reported.
4. A
three-hour emissions average only violates the cumulative occurrence limit n of
an emission level Ef on the day containing the last hour
in the average.
5. Multiple
violations of the same cumulative occurrence limit on the same day and
violations of different cumulative occurrence limits on the same day constitute
a single violation of
R18-2-715(G).
6. The violation of any cumulative occurrence
limit and an annual average emission limit on the same day constitutes only a
single violation of the requirements of
R18-2-715(G).
7. Multiple violations of a cumulative
occurrence limit by different three-hour emissions averages containing any
common hour constitutes a single violation of
R18-2-715(G).
8. To determine compliance with subsections
(R)(1) through (7), the compliance period consists of the 365 calendar days
immediately preceding the end of each day of the month being reported unless
that period includes less than 300 operating days, in which case the number of
days preceding the last day of the compliance period shall be increased until
the compliance period contains 300 operating days. For purposes of this
Section, an operating day is any day on which sulfur-containing feed is
introduced into the smelting process.
S. To determine compliance with
R18-2-715(G), the
owner or operator of the smelter subject to
R18-2-715(G)
shall install, calibrate, maintain, and operate a measurement system for
continuously monitoring sulfur dioxide concentrations of the converter roof
fugitive emissions.
1. For purposes of this
subsection, continuous monitoring means the taking and recording of at least
one measurement of sulfur dioxide concentration from an approved measurement
location in each 15-minute period. Fifteen-minute periods start at the
beginning of each clock hour, and run consecutively. An hour of smelter
emissions is considered continuously monitored if the emissions from all
approved measurement locations are measured for at least 45 minutes of any hour
according to the requirements of this subsection.
2. The owner or operator of a smelter subject
to the requirements of this subsection shall conduct quality assurance
procedures on the continuous monitoring system according to the methods in 40
CFR 60, Appendix F, except that an annual relative accuracy test audit (RATA)
is not required.
T. TThe
emission limit in
R18-2-715(G)
applies to the total of uncaptured fugitive sulfur dioxide emissions from the
smelter processing units and sulfur dioxide control and removal equipment, but
not emissions due solely to the use of fuel for space heating or steam
generation. The owner or operator shall determine compliance with the emission
limit contained in
R18-2-715(G) as
follows:
1. The owner or operator shall
calculate annual average fugitive emissions at the end of the last day of each
month by averaging the monthly emissions for the previous 12-month period
ending on that day. To determine monthly fugitive emissions, the owner or
operator shall perform material balances for sulfur according to the sulfur
balance procedures prescribed in Appendix 8 of this Chapter.
2. An annual emissions average in excess of
the allowable annual average emission limit violates
R18-2-715(G) if
the fugitive annual average computed at the end of each month exceeds the
allowable annual average emission limit.
U. The emission limit in
R18-2-715(H)
applies to the total of stack and uncaptured fugitive sulfur dioxide emissions
from the smelter processing units and sulfur dioxide control and removal
equipment, but not emissions due solely to the use of fuel for space heating or
steam generation. The owner or operator shall determine compliance with the
emission limit contained in
R18-2-715(H) as
follows:
1. The owner or operator shall
calculate annual average stack emissions at the end of the last day of each
month by averaging the emissions for all hours measured during the previous
12-month period ending on that day according to the requirements contained in
subsection (K).
2. The owner or
operator shall calculate annual average fugitive emissions at the end of the
last day of each month by averaging the monthly emissions for the previous
12-month period ending on that day. To determine monthly fugitive emissions,
the owner or operator shall perform material balances for sulfur according to
the sulfur balance procedures prescribed in Appendix 8 of this
Chapter.
3. An annual emissions
average in excess of the allowable annual average emission limit violates
R18-2-715(H) if
the total of the stack and fugitive annual averages computed at the end of each
month exceeds the allowable annual average emission limit.
V. The owner and operator of the copper
smelter located near Hayden, Arizona at the latitude and longitude provided in
R18-2-715(F)(1)
shall comply with Section
R18-2-715.01 until the effective
date of R18-2-B1302 as determined by
