Sec. 61.164 Test methods and procedures.
(a) To demonstrate compliance with Sec. 61.162, the owner or
operator shall conduct emission tests, reduce test data, and follow the
procedures specified in this section unless the Administrator:
(1) Specifies or approves, in specific cases, the use of a reference
method with minor changes in methodology;
(2) Approves the use of an equivalent method;
(3) Approves the use of an alternative method the results of which
he has determined to be adequate for indicating whether a specific
source is in compliance; or
(4) Waives the requirement for emission tests as provided under
Sec. 61.13.
(b) Unless a waiver of emission testing is obtained, the owner or
operator shall conduct emission tests required by this section:
(1) No later than 90 days after the effective date of this subpart
for a source that has an initial startup date preceding the effective
date; or
(2) No later than 90 days after startup for a source that has an
initial startup date after the effective date.
(3) At such other times as may be required by the Administrator
under section 114 of the Act.
(4) While the source is operating under such conditions as the
Administrator may specify, based on representative performance of the
source.
(c) To demonstrate compliance with Sec. 61.162(a)(1) when less than
8.0 Mg (8.8 ton) per year of elemental arsenic is added to any existing
glass melting furnace, or to demonstrate compliance with Sec.
61.162(b)(1) when less than 1.0 Mg (1.1 ton) per year of elemental
arsenic is added to any new or modified glass melting furnace, an owner
or operator shall:
(1) Derive a theoretical uncontrolled arsenic emission factor (T),
based on material balance calculations for each arsenic-containing glass
type (i) produced during the 12-month period, as follows:

each glass type (i).
Wci = Weight of cullet melted per unit weight of glass
produced for each glass type (i), g/kg (lb/ton).

(2) Estimate theoretical uncontrolled arsenic emissions for the 12-
month period for each arsenic-containing glass type as follows:

the 12-month period for each glass type, Mg/year (ton/year).
[[Page 131]]
Ti = Theoretical uncontrolled arsenic emission factor for
each type of glass (i) produced during the 12-month period as calculated
in paragraph (c)(1) of this section, g/kg (lb/ton).

produced during the 12-month period, kg/yr (ton/yr).
K = conversion factor for unit consistency, 10\6\ g/Mg (2,000 lb/ton).
(3) Estimate the total theoretical uncontrolled arsenic emissions
for the 12-month period by finding the sum of the values calculated for
Yi in paragraph (c)(2) of this section.
(4) If the value determined in paragraph (c)(3) of this section is
equal to or greater than the applicable limit in Sec. 61.162(a)(1) or
(b)(1), conduct the emission testing and calculations described in
paragraphs (d)(1) through (d)(5) of this section. If the value is less
than the applicable limit, the source is in compliance and no emission
testing or additional calculations are required.
(d) To demonstrate compliance with Sec. 61.162(a)(1) when 8.0 Mg
(8.8 ton) per year or more of elemental arsenic are added to any
existing glass melting furnace, or to demonstrate compliance with Sec.
61.162(b)(1) when 1.0 Mg (1.1 ton) per year or more of elemental arsenic
is added to any new or modified glass melting furnace, an owner or
operator shall:
(1) Estimate the theoretical uncontrolled arsenic emissions for each
glass type for the 12-month period by performing the calculations
described in paragraphs (c)(1) and (c)(2) of this section.
(2) Conduct emission testing to determine the actual uncontrolled
arsenic emission rate during production of the arsenic-containing glass
type with the highest theoretical uncontrolled arsenic emissions as
calculated under paragraph (d)(1) of this section. The owner or operator
shall use the following test methods and procedures:
(i) Use Method 108 in appendix B to this part for determinig the
arsenic emission rate, g/hr (lb/hr). The emission rate shall equal the
arithmetic mean of the results of three 60-minute test runs.
(ii) Use the following methods in appendix A to 40 CFR part 60:
(A) Method 1 for sample and velocity traverse.
(B) Method 2 for velocity and volumetric flowrate.
(C) Method 3 for gas analysis.
(D) For sources equipped with positive pressure fabric filters, use
Section 8.0 of Method 5D to determine a suitable sampling location and
procedure.
(3) Determine the actual uncontrolled arsenic emission factor
(Ra) as follows:

(d)(2) of this section, g/hr (lb/hr).
P = Rate of glass production, kg/hr (ton/hr), determined by dividing the
weight of glass pulled from the furnace during the emission test by the
number of hours taken to perform the test under paragraph (d)(2) of this
section.
(4) Calculate a correction factor to relate the theoretical and the
actual uncontrolled arsenic emission factors as follows:
F = Ra / Ti
Where:
F=the correction factor.
Ra = Actual uncontrolled arsenic emission factor, determined
in paragraph (d)(3) of this section, g/kg (lb/ton).

section.

less than the applicable limit in Sec. 61.162(a)(1) or (b)(1), the
source is in compliance.
(e) To demonstrate compliance with Sec. 61.162(a)(2) or (b)(2), an
owner or operator shall:
(1) Conduct emission testing to determine the percent reduction of
inorganic arsenic emissions being achieved by the control device, using
the following test methods and procedures:
(i) Use Method 108 in appendix B to this part to determine the
concentration of arsenic in the gas streams entering and exiting the
control device. Conduct three 60-minute test runs, each consisting of
simultaneous testing of the inlet and outlet gas streams. The gas
streams shall contain all the gas exhausted from the glass melting
furnace.
(ii) Use the following methods in appendix A to 40 CFR part 60:
(A) Method 1 for sample and velocity traverses.
(B) Method 2 for velocity and volumetric flowrate.
(C) Method 3 for gas analysis.
(D) For sources equipped with positive pressure fabric filters, use

(3) Determine the average percent reduction of arsenic by
calculating the arithmetic mean of the results for the three runs. If it
is at least 85 percent, the source is in compliance.
