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 gasborne material which exceeds 20% opacity except during the times specified in subsection (D). B. No person shall cause, allow or 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 0.1 grain per cubic foot, based on dry flue gas at standard conditions, corrected to 12% 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 12% carbon dioxide. C. Air curtain destructors shall not be used within 500 feet of the nearest dwelling. D. Incinerators shall be exempt from the opacity and emission requirements described in subsections (A) and (B) 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 30 seconds in any 60-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 60 minutes, and b. For an upset of operations not to exceed three minutes in any 60-minute period. E. The owner or operator of any incinerator subject to the provisions of this Section shall record the daily charging rates and hours of operation. F. 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 (B) as follows: a. Method 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 60 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 Director.
