Jul 01, 2016 · or boiler capacity/heater size, and the effect of the limits keeps emissions below the major source thresholds. The boiler permits also limit fuel sulfur content as a means to keep SO. 2 emissions below the major source thresholds. Visible emissions and opacity requirements are in all of the state permits, but they vary from state to state.
