TITLE 40--PROTECTION OF ENVIRONMENT
CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 63_NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR
SOURCE CATEGORIES--Table of Contents
Subpart AAAAA_National Emission Standards for Hazardous Air Pollutants
for Lime Manufacturing Plants
Sec. 63.7112 What performance tests, design evaluations, and other
procedures must I use?
(a) You must conduct each performance test in Table 4 to this
subpart that applies to you.
(b) Each performance test must be conducted according to the
requirements in Sec. 63.7(e)(1) and under the specific conditions
specified in Table 4 to this subpart.
(c) You may not conduct performance tests during periods of startup,
shutdown, or malfunction, as specified in Sec. 63.7(e)(1).
(d) Except for opacity and VE observations, you must conduct three
separate test runs for each performance test required in this section,
as specified in Sec. 63.7(e)(3). Each test run must last at least 1
hour.
(e) The emission rate of particulate matter (PM) from each lime kiln
(and each lime cooler if there is a separate exhaust to the atmosphere
from the lime cooler) must be computed for each run using Equation 1 of
this section:
[GRAPHIC] [TIFF OMITTED] TR05JA04.000
Where:
E = Emission rate of PM, pounds per ton (lb/ton) of stone feed.
Ck = Concentration of PM in the kiln effluent, grain/dry
standard cubic feet (gr/dscf).
Qk = Volumetric flow rate of kiln effluent gas, dry standard
cubic feet per hour (dscf/hr).
Cc = Concentration of PM in the cooler effluent, grain/dscf.
This value is zero if there is not a separate cooler exhaust to the
atmosphere.
Qc = Volumetric flow rate of cooler effluent gas, dscf/hr.
This value is zero if there is not a separate cooler exhaust to the
atmosphere.
P = Stone feed rate, tons per hour (ton/hr).
K = Conversion factor, 7000 grains per pound (grains/lb).
(f)(1) If you choose to meet a weighted average emission limit as
specified in item 4 of Table 1 to this subpart, you must calculate a
combined particulate emission rate from all kilns and coolers within
your LMP using Equation 2 of this section:
[GRAPHIC] [TIFF OMITTED] TR05JA04.001
Where:
ET = Emission rate of PM from all kilns and coolers, lb/ton
of stone feed.
Ei = Emission rate of PM from kiln i, or from kiln/cooler
combination i, lb/ton of stone feed.
Pi = Stone feed rate to kiln i, ton/hr.
n = Number of kilns you wish to include in averaging.
(2) You do not have to include every kiln in this calculation, only
include kilns you wish to average. Kilns that have a PM emission limit
of 0.60 lb/tsf are ineligible for any averaging.
(g) The weighted average PM emission limit from all kilns and
coolers for which you are averaging must be calculated using Equation 3
of this section:
[[Page 42]]
[GRAPHIC] [TIFF OMITTED] TR05JA04.002
Where:
ETN = Weighted average PM emission limit for all kilns and
coolers being included in averaging at the LMP, lb/ton of stone feed.
Ej = PM emission limit (0.10 or 0.12) for kiln j, or for
kiln/cooler combination j, lb/ton of stone feed.
Pj = Stone feed rate to kiln j, ton/hr.
m = Number of kilns and kiln/cooler combinations you are averaging at
your LMP. You must include the same kilns in the calculation of
ET and ETN. Kilns that have a PM emission limit of
0.60 lb/tsf are ineligible for any averaging.
(h) Performance test results must be documented in complete test
reports that contain the information required by paragraphs (h)(1)
through (10) of this section, as well as all other relevant information.
The plan to be followed during testing must be made available to the
Administrator at least 60 days prior to testing.
(1) A brief description of the process and the air pollution control
system;
(2) Sampling location description(s);
(3) A description of sampling and analytical procedures and any
modifications to standard procedures;
(4) Test results, including opacity;
(5) Quality assurance procedures and results;
(6) Records of operating conditions during the test, preparation of
standards, and calibration procedures;
(7) Raw data sheets for field sampling and field and laboratory
analyses;
(8) Documentation of calculations;
(9) All data recorded and used to establish operating limits; and
(10) Any other information required by the test method.
(i) [Reserved]
(j) You must establish any applicable 3-hour block average operating
limit indicated in Table 2 to this subpart according to the applicable
requirements in Table 3 to this subpart and paragraphs (j)(1) through
(4) of this section.
(1) Continuously record the parameter during the PM performance test
and include the parameter record(s) in the performance test report.
(2) Determine the average parameter value for each 15-minute period
of each test run.
(3) Calculate the test run average for the parameter by taking the
average of all the 15-minute parameter values for the run.
(4) Calculate the 3-hour operating limit by taking the average of
the three test run averages.
(k) For each building enclosing any PSH operations that is subject
to a VE limit, you must conduct a VE check according to item 18 in Table
4 to this subpart, and in accordance with paragraphs (k)(1) through (3)
of this section.
(1) Conduct visual inspections that consist of a visual survey of
the building over the test period to identify if there are VE, other
than condensed water vapor.
(2) Select a position at least 15 but not more 1,320 feet from each
side of the building with the sun or other light source generally at
your back.
(3) The observer conducting the VE checks need not be certified to
conduct EPA Method 9 in appendix A to part 60 of this chapter, but must
meet the training requirements as described in EPA Method 22 in appendix
A to part 60 of this chapter.
(l) When determining compliance with the opacity standards for
fugitive emissions from PSH operations in item 7 of Table 1 to this
subpart, you must conduct EPA Method 9 in appendix A to part 60 of this
chapter according to item 17 in Table 4 to this subpart, and in
accordance with paragraphs (l)(1) through (3) of this section.
(1) The minimum distance between the observer and the emission
source shall be 4.57 meters (15 feet).
(2) The observer shall, when possible, select a position that
minimizes interference from other fugitive emission sources (e.g., road
dust). The required observer position relative to the sun must be
followed.
(3) If you use wet dust suppression to control PM from PSH
operations, a visible mist is sometimes generated by the spray. The
water mist must not be confused with particulate matter emissions and is
not to be considered VE. When a water mist of this nature is present,
you must observe emissions at a point in the plume where the mist is no
longer visible.
