Test data shall establish the highest level of PM, HCl and D&F that will be emitted from the furnace. Subject to department approval of the OM&M plan, this may be determined by conducting performance tests and monitoring operating parameters while charging the furnace with feed or charge materials containing the highest anticipated levels of oils and coatings and fluxing at the highest anticipated rate.
