(1) Small Incinerators. Any incinerator, other than a biological waste incinerator, human or animal crematory, or air curtain incinerator, with a charging rate of less than 50 tons per day shall comply with the following requirements.
    (a) Emission Limiting Standards. Visible emissions shall not exceed 5% opacity except that visible emissions not exceeding 15% opacity are allowed for one six-minute period in any one-hour period.
    (b) Test Methods and Procedures. All emissions tests performed pursuant to the requirements of this subsection shall comply with the following requirements.
    1. The reference test method for visible emissions shall be EPA Method 9, as described at 40 CFR, Part 60, Appendix A-4, adopted and incorporated by reference at Fl. Admin. Code R. 62-204.800
    2. Test procedures shall conform to the procedures specified in Fl. Admin. Code R. 62-297.310 All test results shall be reported to the Department in accordance with the provisions of Fl. Admin. Code R. 62-297.310
    (c) Frequency of Testing. The owner or operator of an incinerator subject to this subsection shall have a performance test conducted for visible emissions prior to submitting the application for an initial air operation permit, and annually thereafter.
    (2) Existing incinerators, other than those which are operated or utilized for the disposal or treatment of biological waste, with a charging rate equal to or greater than 50 tons per day shall comply with the following requirements. For the purposes of this subsection, an “”existing incinerator”” is an incinerator which was in existence, in operation, or under construction, or had received a permit to begin construction prior to January 18, 1972.
    (a) Particulate matter – 0.1 grains per standard cubic foot dry gas corrected to 50 percent excess air.
    (b) No objectionable odor allowed.
    (c) Test Methods and Procedures. All emissions tests performed pursuant to the requirements of this rule shall comply with the following requirements.
    1. The test method for particulate emissions shall be EPA Method 5, as described at 40 C.F.R. part 60, Appendix A-3, adopted and incorporated by reference at Fl. Admin. Code R. 62-204.800 The minimum sample volume shall be 30 dry standard cubic feet. EPA Method 3 or 3A, using Orsat analysis is required for percent excess air correction. EPA Methods 3 and 3A, are described at 40 C.F.R. part 60, Appendix A-2, adopted and incorporated by reference at Fl. Admin. Code R. 62-204.800
    2. Test procedures shall meet all applicable requirements of Fl. Admin. Code Chapter 62-297
    (d) Calculations Correcting Concentrations to 50% Excess Air (EA), EPA Method 3, Section 1.2. When correcting a pollutant emission concentration to 50% excess air, pursuant to this rule, the following equation shall be used:
