Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part III - Air › Chapter 25 - Miscellaneous Incineration Rules › Subchapter C - Refuse Incinerators › Section III-2521 - Refuse Incinerators

Current through Register Vol. 50, No. 6, June 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.
