AQ083    §2521;LAd34;LA021.03;AQ083;LR20:1100 to 1101(10/20/1994)

   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.

AQ145   §2521.E;LAd34;LA021.02;AQ145;LR22:1212p22(12/20/1996)
   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 seven 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 ten 
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 bum 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 bum 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 02 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 (HCI) - no refuse incinerators 
shall emit hydrogen chloride in excess of four 
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 HCI control device or shall continuously 
monitor flue gas to show compliance with HCI emission 
limits;
         b. carbon monoxide - 100 ppmv maximum (one hour 
rolling average) dry basis at seven 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:

ash, etc., to become airborne in amounts that will cause a 
public nuisance or cause ambient air quality standards to be
