    (2) Emission Limitations. No owner or operator of an electric arc furnace shall cause, permit, or allow emissions of particulate matter in excess of the following standards:
    (a) Phosphorus electric arc furnaces – 0.035 gr/dscf or any visible emissions (greater than five percent opacity) from a control device, except during tapping periods. No visible emissions greater than 60 percent opacity shall be allowed during the tapping period.
    (b) All other electric arc furnaces – 0.010 gr/dscf or any visible emissions (greater than five percent opacity) from a control device, except during charging and tapping periods. No visible emissions greater than 20 percent opacity shall be allowed from the shop during charging periods. No visible emissions greater than 40 percent opacity shall be allowed during tapping periods.
    (3) Test Methods and Procedures. All emissions tests performed pursuant to the requirements of this rule shall comply with the following requirements.
    (a) The test method for visible emissions shall be EPA Method 9, as described at 40 C.F.R. part 60, Appendix A-4, adopted and incorporated by reference at Fl. Admin. Code R. 62-204.800
    (b) The test method for particulate matter emissions shall be EPA Method 5 or EPA Method 5D, 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.
