(a) Install, calibrate, maintain, and operate a continuous monitoring system
for the measurement of the opacity of emissions discharged into the
atmosphere from the control device. The system shall be located as
specified in paragraph (g), below.
(b) Install, calibrate, maintain, and operate a monitoring device for the
continuous measurement of the temperature of the gas entering the
control device. The system shall be located as specified in paragraph
(g), below.
(c) Reduce all opacity data to 6-minute averages. 6-minute averages shall
be calculated from 24 or more data points equally spaced within each
6-minute period. Data recorded during periods when the monitoring
system breaks down, or is undergoing repairs, calibration checks, or
zero and span adjustments, shall not be included in the data averages
calculated under this paragraph.
(d) Calculate 15-minute averages of the temperature of the gas entering
the control device for each 15-minute operating period.

percent of span value) calibration drifts at least once daily in
accordance with a written procedure. The zero and span shall be
adjusted whenever the 24-hour span drift exceeds 2 times the limits of
the applicable performance specifications in 40 CFR 60, Appendix B.
The system must allow the amount of excess zero and span drift
measured at the 24-hour interval checks to be recorded and quantified,
whenever specified. For continuous monitoring systems measuring
opacity of emissions, the optical surfaces exposed to the effluent gases
shall be cleaned prior to performing the zero and span drift
adjustments except that for systems using automatic zero compensation
exceeds 4 percent opacity.
(f) Unless otherwise approved by the [Agency], adopt the following
procedures for continuous monitoring systems measuring opacity of
emissions. Minimum procedures shall include a method for producing
a simulated zero opacity condition and an upscale (span) opacity

(b) steps taken to minimize arsenic emissions during the period the control
device was bypassed.
D. TEST METHODS AND PROCEDURES
(1) To meet the requirements of Section C of this permit (Reporting & Recordkeeping
Requirements), paragraph (3), the permittee must conduct emission tests, reduce test data,
and follow the procedures specified in this section, unless the [Agency]:
(a) Specifies or approves, in specific cases, the use of a reference method
with minor changes in methodology;

INSTRUCTIONS FOR USE
MODEL PERMIT SPECIFIC CONDITIONS
CFR 40, Part 61, Subpart N
National Emission Standards for
Inorganic Arsenic Emissions from Glass Manufacturing
I. PREFACE TO INSTRUCTIONS
The model permit specific conditions document has been prepared to reflect the
provisions of Section 502(c) of Title V in the Clean Air Act Amendments of 1990, which
states that a single permit may be issued for a facility with multiple sources. Accordingly,
this permit assumes that the facility being permitted:
• has one or more pieces of equipment covered by the
NESHAPs;
• may have more than one piece of the same type of equipment;
and
• each piece of equipment may have several exhaust gas streams.
When preparing an actual permit, the permitting agency should only use those
sections of the model permit specific conditions document that are relevant.
A. THE USE OF TABLES & BLANK SPACES FOR EMISSION LIMITS
Although the NESHAPs prescribe definite emission limits, the model permit specific
conditions document uses blank tables and blank spaces, in which the permitting agency can
enter appropriate emission limits. The reason for using blank tables and spaces is twofold:
First, some state or local regulations may have emission limits that are more stringent than
those in the NESHAPs. In such instances, the permitting agency may choose to use the
more stringent limit. Second, even if state or local regulations do not prescribe more
stringent emission limits (or do not have emission limits at all), the permitting agency may
choose to use actual emission amounts (or concentrations as appropriate) submitted by the
facility in its application for a permit provided that the amounts (or concentrations) are
within the limits established by the NESHAPs, and any applicable state and local
regulations.
In both the cases outlined in the previous paragraph, however, any emission limits
that differ from those presented in the NESHAPs may not be federally enforceable. This
is an issue that has not been resolved during the preparation of these model permits. To
simplify matters, we have inserted limits or other values that are federally enforceable in the
blanks. Agencies, at their own discretion, may choose to use these or other appropriate
values.
Many of the emission limits in the document may be presented via tables; this is done
for the sake of comprehensiveness and to avoid repetitive use of legal terminology.
Page 1 of 8
-------
Instructions
However, such a form of presentation is not a requirement under the NESHAPs, and the
permitting agency may choose to present emission limits individually in a text format. In
other instances blank spaces have been left in the text, in which the permitting agency may
insert the appropriate limit. (Federally enforceable limits are inserted in square brackets.)
The choice of whether to use tables or blank spaces in the document was made as
follows: Whenever the NESHAPs prescribed an emission limit that could apply to several
exhaust gas streams or several pieces of equipment, a table was chosen. Blank spaces
were chosen whenever the NESHAPs prescribed a single emission limit. Permitting
agencies can insert appropriate limits in the tables and blank spaces. Once again, limits
other than those in the NESHAPs may not be federaUy enforceable.
B. USING & MODIFYING TABLES
The tables presented in the document are meant to be examples of tables that the
permitting agency may choose to use. As such, each table is subject to modification by the
permitting agency to fit its needs. Each table has 2 main features: (i) equipment and/or gas
stream identifiers; and (ii) corresponding emission limits. Because a limit is being applied
uniquely to either a piece of equipment or an exhaust gas stream, it is necessary to identify
the equipment or gas stream. The tables have used generic terminology to denote
identifiers. The permitting agency may choose to amend the terminology to suit its
individual requirements, provided amended terminology uniquely identifies the equipment
or gas stream, typically by cross-reference to a process flow diagram, etc.
There is likely to be considerable variation in the number of pieces of equipment
covered by different sections of a permit (both, within a single permit, as well as between
one permit and another). Therefore, the permitting agency will need to modify each table
to reflect the correct number of pieces of equipment. To complete the emission limit
columns in the tables, the permitting agency may choose to simply use the limits prescribed
by the NESHAPs (as shown in the square brackets). Alternatively, the agency may choose
to insert other appropriate limits.
C. OTHER CONSIDERATIONS
In addition to blank spaces left for emission limits, blank spaces have been left for
other reasons throughout the model permit specific conditions document, including:
• spaces for the permitting agency to insert its name; and
• spaces that allow the permitting agency to insert other
information that may vary from state to state (such as the
length of time that permittees must keep records).
D. A NOTE ON EMISSIONS TESTING
The NESHAPs require facility owners/operators to conduct emission testing as
follows (unless they obtain a waiver of emission testing):
Page 2 of 8
-------
Instructions
• within 90 days of the effective data of the regulations in the case of
existing sources or new sources with an initial startup date preceding
the effective date; or
• within 90 days of startup in the case of new sources that have an initial
startup date after the effective date of the regulations.
These provisions have been interpreted as one-time testing requirements; as such they are
not on-going operational requirements. Furthermore, because they are required only at the
time of startup, these provisions are judged to be more appropriate in a construction permit
rather than an operating permit. For these reasons, these testing requirements are not
included in this model permit document.
II. INSTRUCTIONS
In the sections that follow, information is presented on regulatory requirements under
40 CFR 61, Subpart N. Typically, these sections explain the basis for each of the conditions
in the model permit specific conditions document, and provide references that the
permitting agency may use for additional clarification or details. To facilitate using these
instructions, each section and subsection below corresponds to the sections and subsections
in the permit document.
A. EMISSION LIMITS
(1) This section establishes emission limits for existing glass melting furnaces with and
without control devices. A table is used in this section to clearly show the permittee the
emission limits that apply to each furnace. The permit writer should first determine whether
the glass melting furnace does/does not use an emission control device. If the furnace does
not use an emission control device, the furnace is considered uncontrolled. The emission
limit that applies to existing uncontrolled furnaces according to §61.162 is 2.5 Mg per year]
total arsenic emissions. For new or modified, uncontrolled glass melting furnaces the
emission limit that applies, is 0.4 Mg per year total arsenic emissions.
New or existing/modified glass melting furnaces whose emissions are directed to a
control device are subject to different emission limits. Emission limits for these types of
furnaces are calculated by reducing the total uncontrolled arsenic emissions from the
furnace in proportion to the control efficiency of the device. §61.162 requires a control
efficiency of at least 85 percent. This limit can be calculated by the formula:
E, = Et * (1 - 6)
where:
Ej = emission limit
E, = total uncontrolled arsenic emissions
6 = control efficiency of the control device.

Instructions
The footnote on Page 1 of the permit is for reference purposes of the permitting
agency only, and is not meant to be included in an actual permit.
Example Table 1 illustrates the calculation of emissions limits for different furnaces.
Furnaces 1, 2, and 3 are existing furnaces, and furnaces 4, and 5 are new. Furnaces 1 and
2, being uncontrolled existing furnaces, are subject to a limit of 2.5 Mg/year under the
NESHAPs. In this case, the permit writer has decided to use the current uncontrolled
emission rates of 2.4 Mg/year and 1.2 Mg/year as more stringent requirements for furnaces
1 and 2. Furnaces 3 and 4 have control devices and are subject to the limit of an 85 percent
reduction in uncontrolled emissions. The permit writer has filled in the control device
I.D. # and control efficiency. The emission limits for furnaces 3 and 4 were determined by
using the formula above. Furnace 5 being a new, uncontrolled furnace is subject to an
emission limit of 0.4 Mg/year under the NESHAPs. The permit writer has again chosen to
use the uncontrolled emission rate of 0.3 Mg/year as the limit, which is more stringent than
the NESHAP limit.

According to the NESHAP, Subpart N, uncontrolled emissions may be conveyed to
a control device and reduced by 85 percent. A statement to that effect may be placed into
Section A of the permit. By taking an uncontrolled furnace and installing a control device,
the permittee might be able to increase the uncontrolled emissions of the furnace as long
as the emissions are reduced by 85 percent by the control device. This action would require
that the permittee notify the [Agency] of the action taken and report any increase in
emissions. The [Agency] may also require revision of the permit to incorporate the new
emission limit.
If a furnace has multiple emission points, each emission point for a single furnace
should be listed on consecutive lines in Table 1 of Section A (Emission Limits) in the model
permit specific conditions document. To calculate emission limits for multiple emission
points from a single furnace, the permit writer should consider that the emission limit for
Page 4 of 8
-------
Instructions
a single emission point furnace would be the same as the sum of all the emissions from a
multiple emission point furnace, because the limit is established for a furnace, not for
individual emission points. To calculate the emission limits for a furnace with multiple
sources, divide the total emissions by the number of emission sources (see Example 2).
Example 2: Furnace 1 and Furnace 6 are existing, uncontrolled furnaces
emitting 2.5 Mg per year each. Furnace 1 has a single emission
point, and Furnace 6 has four emission points. According to
the NESHAPs, Furnace 6 has the same total emission limit as
Furnace 1. However, the permitting agency may choose to
impose an emission limit for each emission point as follows:
No. of Emission Points = 4
Emission Limit = (2.5 -=- 4) Mg per year
= 0.63 Mg per year for each emission point.
This calculation assumes that all emission points have equal flow. To determine
emission Limits for points that do not have equal flow, use the percentage of total flow for
each emission point. The percentage of flow for each emission point is multiplied by the
emission amount for the entire furnace to get the emission limits for each emission point.
Note: The sum of the emission limits from sources with multiple emission points must total
the limit as if the source had only a single emission point.
(2) This condition is based on §61.162(c). Application procedures are described in CFR
40 61.165(e).
(3) This condition is based on §61.162(d).
B. EMISSION MONITORING
1) This condition prescribes procedures for the permittee to follow if the permittee has
a furnace that uses an emission control device. If the permittee has only uncontrolled
furnaces, this section may be omitted.
(a) Specific condition for opacity monitoring, as required by §61.163(a)(l).
(b) Specific condition for temperature monitoring, as required by §61.163(a)(2).
(c) This condition specifies data treatment for opacity data, as required by §61.163(g)(l).
(d) This condition specifies data treatment for temperature data, as required by
§61.163(g)(2).
(e) This condition specifies zero and span adjustment for continuous emission monitoring
systems, as required by §61.163(e) and 60.13(d)(l).
Page 5 of 8
-------
Instructions
(f) This condition specifies zero and span adjustment for continuous monitoring systems
measuring opacity, as required by §61.163(e) and §60.13(d)(2).
(g) This condition refers the permittee to the appropriate procedures for installing the
continuous monitoring system, and is based on §61.163(e) and §60.13(f)
requirements. 40 CFR 60, Appendix B is the reference for the procedures.
(h) This condition specifies frequency of operation requirements for continuous
monitoring systems, as required by §61.163(f) and 60.13(e).
C. REPORTING AND RECORDKEEPING REQUIREMENTS
(1) This section describes requirements and procedures used when the furnace has an
emission control device and is subject to continuous monitoring. The permit writer may
delete this section if none of the furnaces have emission control devices and are not subject
to continuous monitoring requirements. §61.165(a) is the basis for this set of conditions.
(2) This section lists the procedures for recording and reporting emission levels and
methods for calculating required emissions information, as required by §61.165(c)(l). It only
pertains to existing glass melting furnaces with uncontrolled total arsenic emissions, where
less than 8.0 Mg per year of elemental arsenic is added to the furnace, and to new or
modified uncontrolled glass melting furnaces where less than 1.0 Mg per year of elemental
arsenic is added to the furnace. This information has been put in square brackets only to
serve as a reference for the permitting agency, and must not appear in the actual permit.
If the facility being permitted does not have uncontrolled total arsenic emissions, then
Section C(2) does not apply, and must not be included in the permit. If a facility has some
furnaces with controlled emissions but others with uncontrolled emissions, Section C(2)
applies only to the furnaces with uncontrolled emissions, and this must be specified in the
permit.
§61.165(c) describes 3 steps that the facility must take:
(i) derive a theoretical uncontrolled arsenic emission factor;
(ii) estimate theoretical uncontrolled arsenic emissions for each arsenic-
containing glass type; and
(iii) estimate the total theoretical uncontrolled arsenic emissions for all
glass types.
These 3 steps are outlined in paragraphs 2(a) through 2(c) of the permit.
(3) This section, which is also required by §61.165(c)(l), only pertains to existing glass
melting furnaces with uncontrolled total arsenic emissions, where 8.0 Mg per year or more
of elemental arsenic is added to the furnace, and to new or modified uncontrolled glass
melting furnaces where 1.0 Mg per year or more of elemental arsenic is added to the
furnace. This information has been put in square brackets only to serve as a reference for
the permitting agency, and must not appear in the actual permit.

-------
Instructions
Section C(3) does not apply if the permitted facility does not have uncontrolled total
arsenic emissions, and must not be included in the permit. If a facility has some furnaces
with controlled emissions but others with uncontrolled emissions, Section C(3) applies only
to the furnaces with uncontrolled emissions, and this must be specified in the permit.
§61.165(d), which is referenced in §61.165(c)(l), requires emissions testing. This
requirement is reflected in paragraph (3) of the permit.
(4) This is a requirement of §61.165(c)(2).
(5) This section establishes notification deadlines for emission tests, as required by
§61.165(d)(2), (4), and (5).
(6) This condition applies to permittees who are required to operate a continuous opacity
monitoring system. The condition reflects the requirements of §61.165(f)(l) and (2). If
continuous opacity monitoring is not required of the permittee, this condition should be
omitted from the permit.
(7) This condition outlines additional information that the permittee must report, if
required to operate a continuous opacity monitoring system. The condition reflects the
requirements of §61.165(f)(3). If continuous opacity monitoring is not required of the
permittee, this condition should be omitted from the permit.
(8) This condition refects the requirements of §61.165(b), and only applies to permittees
with agency approval to bypass a control device under Condition A(l) of the permit. This
condition should be omitted if the permittee is not bypassing control devices.
D. EMISSIONS TESTING REQUIREMENTS
(1) This paragraph, based on §61.164(a), outlines circumstances when the permittee may
deviate from emission testing and calculation procedures required by the permit.
(2-6) These steps are part of the emissions testing procedures, described in §61.164(d).
These conditions only apply to permittees with existing with uncontrolled total arsenic
emissions, where 8.0 Mg per year or more of elemental arsenic is added to the furnace, and
to permittees with new or modified uncontrolled furnaces where 1.0 Mg per year or more
of elemental arsenic is added to the furnace; or when emissions testing is required for some
other reason, as outlined in §61.164(b)(3) and (4).
The steps, as outlined in paragraphs (2) through (6), that the facility must take are:
(i) derive a theoretical uncontrolled arsenic emission factor and estimate
theoretical uncontrolled arsenic emissions for each arsenic-containing
glass type;
(ii) conduct emissions testing;
(iii) determine actual uncontrolled arsenic emission factor;

(iv) calculate a correction factor for the theoretical emission factor; and
(v) determine the uncontroled emission rate.
(7) This condition is based on the requirements of §61.165(d)(l).
