Current through Register Vol. 50, No. 9, September 20, 2024
A.
Scope. The purpose of this Subchapter is to prevent the operation or
construction of refuse incinerators in such a manner as to cause air
pollution.
B. Applicability. This
Subchapter applies to all incinerators operated or constructed in the state for
the purpose of reducing refuse.
C.
Determination of Incinerator Maximum Burning Capacity. The burning capacity of
a refuse incinerator shall be the manufacturer's or designer's guaranteed
maximum rate or such other rate as may be determined by the department in
accordance with good engineering practices. In case of conflict, the
determination made by the department shall govern.
D. All Incinerators Must Be Approved Prior to
Installation. All refuse incinerators must be approved by the department prior
to installation. Any person planning to install or operate a refuse incinerator
must make suitable application to the department. Forms are available from the
department.
E. Allowable Emissions
from Incinerator. The amount of particulate matter
(PM10) emitted by a refuse incinerator shall be
determined using the test methods from 40 CFR Part 60, Appendix A, as
incorporated by reference at LAC 33:III.3003: Method 5 - Determination of
Particulate Emissions from Stationary Sources ( 40 CFR Part 60, Appendix A, as
incorporated by reference at LAC 33:III.3003).
F. Restrictions on Emissions
1. No person shall cause or permit the
emissions of PM10 from any refuse incinerator (with a
capacity less than 250 pounds-per-hour) in excess of 0.10 grains per dry
standard cubic foot of dry flue gas corrected to 7 percent excess oxygen or 12
percent carbon dioxide. PM10 emission limits for larger
incinerators are:
|
Capacity
|
PM10
|
|
250-499 pounds-per-hour
|
0.08
|
|
500-1000 pounds-per-hour
|
0.06
|
|
Over 1000 pounds-per-hour
|
0.04
|
2.
All refuse incinerators must be multi-chambered or equivalent as determined by
the department. All multi-chambered incinerators must be equipped with
secondary burners of such a design as to assure a temperature in the secondary
chamber of at least 1500°F for at least 0.5 seconds for incinerators with a
capacity less than 250 pounds-per-hour. The minimum secondary chamber
temperature for larger incinerators is:
|
Capacity
|
Temperature
|
|
250-499 pounds-per-hour
|
1500°F for at least 1 second
|
|
500-1000 pounds-per-hour
|
1600°F for at least 1 second
|
|
Over 1000 pounds-per-hour
|
1800°F for at least 1 second
|
3.
All refuse incinerators shall be equipped with an interlock that prevents the
charge door from opening for 10 minutes after the secondary burner is ignited,
or until the secondary chamber exit gases reach 1500°F for incinerators with a
capacity less than 500 pounds-per-hour, 1600°F with a capacity 500-1000
pounds-per-hour, and 1800°F for incinerators with a capacity greater than 1000
pounds-per-hour, whichever occurs first. A visual warning system shall alert
the operator when the interlock is by-passed for service or cleaning.
4. No person shall burn or cause or permit
the burning of refuse in any installation which was designed for the sole
purpose of burning fuel without the authorization of the administrative
authority.
5. All refuse
incinerators shall be designed with a stack emission point which does not
adversely impact the local area air quality. All incinerator stack heights must
be approved by the administrative authority.
6. All secondary combustion chambers shall be
equipped with a continuous temperature recorder to measure and record the exit
flue gas temperature. All refuse incinerators with a capacity greater than 500
pounds-per-hour shall have a continuous monitoring and recording system
installed for CO and O2 concentration in the exit flue
gas.
7. All refuse incinerators
which burn waste generated off-site shall be equipped with an acid gas control
device of 98 percent efficiency, have a continuous monitoring system for CO and
O2, and have a secondary combustion chamber burner
capable of maintaining a minimum temperature of 1800°F for at least one second
in the secondary chamber.
8.
Emission limits for all refuse incinerators shall include:
a. hydrogen chloride (HCl)-no refuse
incinerators shall emit hydrogen chloride in excess of 4 pounds-per-hour, or
they shall operate a control device with a minimum efficiency of 98 percent.
All incinerators over 500 pounds-per-hour design capacity shall be equipped
with a 98 percent efficient HCl control device or shall continuously monitor
flue gas to show compliance with HCl emission limits;
b. carbon monoxide-100 ppmv maximum (one hour
rolling average) dry basis at 7 percent oxygen;
c. nitrogen dioxide-250 ppmv maximum dry
basis at seven percent oxygen;
d.
excess oxygen in flue gas-2 percent minimum by volume dry basis;
e. opacity of stack gases shall not exceed 10
percent; and
f. sulfur dioxide-100
ppmv maximum dry basis at 7 percent oxygen or 70 percent control.
9. All refuse incinerators with a
design charging rate in excess of 250 pounds-per-hour shall conduct emission
tests to verify compliance with this Subsection for PM10
and HCl. In addition, all refuse incinerators with a design charging rate of
500 pounds or more per hour shall conduct emission tests to verify compliance
with the standards for the following pollutants using the test methods from 40
CFR Part 60, Appendix A:
a. Method
5-Determination of Particulate Emissions from Stationary Sources (40 CFR Part
60, Appendix A, as incorporated by reference at LAC 33:III.3003);
b. Method 6-Determination of Sulfur Dioxide
Emissions from Stationary Sources ( 40 CFR Part 60, Appendix A, as incorporated
by reference at LAC 33:III.3003);
c. Method 7-Determination of Nitrogen Oxide
Emissions from Stationary Sources ( 40 CFR Part 60, Appendix A, as incorporated
by reference at LAC 33:III.3003);
d. Method 26-Determination of Hydrogen
Chloride Emissions from Stationary Sources ( 40 CFR Part 60, Appendix A, as
incorporated by reference at LAC 33:III.3003); and/or
e. other tests which may be added at pretest
meetings.
10. At least
30 days prior to performing any emission test, notification of testing shall be
made to the Office of Environmental Services to afford the department the
opportunity to conduct a pretest conference and to have an observer
present.
11. A copy of all
monitoring and tests results shall be submitted to the Office of Environmental
Services for review and approval within 60 days of completion of
testing.
G. Control of
Particulate Matter. No person shall cause or permit the handling, use,
transport, or storage of any material in a manner which allows or may allow
particulate matter, fly ash, etc., to become airborne in amounts that will
cause a public nuisance or cause ambient air quality standards to be
violated.
H. All Incinerator
Equipment to be Kept in Good Working Condition. All equipment, accessories, and
appurtenances, (i.e., secondary burners, etc.) of a refuse incinerator
installation shall be maintained in proper working condition and shall be
operational at all times when the refuse incinerator is in use. (See also LAC
33:III.905 and 915.E)
