A. An incinerator shall be operated only between the hours of official sunrise and sunset, except when the following are conditions of the operating permit:
1. The incinerator is equipped with a continuous monitoring and recording opacity meter;
2. The incinerator is used solely for the destruction of materials which would cause or contribute to air pollution if disposed of in any other practical manner;
3. The incinerating process cannot be operated efficiently during only daylight hours;
4. The opacity monitoring-and-recording equipment is calibrated and maintained in accordance with the manufacturer's specifications; and
5. The opacity monitoring records are kept for at least five years.
B. No person shall cause, allow, or permit to be emitted into the atmosphere, from any type of incinerator, smoke, fumes, gases, particulate matter or other gas-borne material which exceeds twenty percent opacity except during the times specified in subsection E of this section.
C. No person shall cause, allow, permit the discharge of particulate matter into the atmosphere in any one hour from any incinerator, in excess of the following limits:
1. For multiple chamber incinerators, controlled atmosphere incinerators, fume incinerators, afterburners or other unspecified types of incinerators, emissions shall not exceed 0.08 grains per cubic foot, based on dry flue gas at standard conditions, corrected to twelve percent carbon dioxide.
2. For wood waste burners other than air curtain destructors, emissions discharged from the stack or burner top opening shall not exceed 0.2 grain per cubic foot, based on dry flue gas at standard conditions, corrected to twelve percent carbon dioxide.
D. Air curtain destructors shall not be used within five hundred feet of the nearest dwelling.
E. Incinerators shall be exempt from the opacity and emission requirements described in subsections B and C of this section as follows:
1. For multiple chamber incinerators, controlled atmosphere incinerators, fume incinerators, afterburners or other unspecified types of incinerators, such exemption shall be for not more than thirty seconds in any sixty-minute period.
2. Wood waste burners shall be exempt both:
a. For a period once each day for the purpose of building a new fire but not to exceed sixty minutes, and
b. For an upset of operations not to exceed three minutes in any sixty-minute period.
F. The owner or operator of any incinerator subject to the provisions of this section shall record the daily charging rates and hours of operation.
G. The test methods and procedures required by this section are as follows:
1. The reference methods in 40 CFR 60, Appendix A, shall be used to determine compliance with the standards prescribed in subsection C of this section as follows:
a. Methods 4 and 5 for the concentration of particulate matter and the associated moisture content;
b. Method 1 for sample and velocity traverses;
c. Method 2 for velocity and volumetric flow rate;
d. Method 3 for gas analysis and calculation of excess air, using the integrated sampling technique.
2. For Method 5, the sampling time for each run shall be at least sixty minutes and the minimum sample volume shall be 0.85 dscm (30.0 dscf) except that smaller sampling times or sample volumes, when necessitated by process variables or other factors, may be approved by the control officer.
