Tables 1-4 give an overview of current TSP control capabilities of fabric filters on some applications. Very little data is available as to the control of PM{sub 10} and under. Most air toxic limitations will require much higher control as can be seen in Tables 5 and 6. The control of most air toxics is definitely related to the control of TSP and PM{sub 10}, however it appears that meeting current limits of TSP do not ensure meeting the desired air toxic limits. Since TSP is desired to be used as a surrogate and is all that is routinely monitored through opacity or other stack CEM systems, lower TSP limits would have to be met which opens the question of how accurate we can monitor TSP or PM{sub 10} on a continuous basis. Tables 3 and 4 provide some insight as to the uniformity of TSP results between identical operating units and over time at two NSW installation. Except for the 9/10/91 test, the baghouses were inspected for failing bags prior to testing. Tables 7 and 8 show the impact of TSP and air toxic metals of a plant upset. In this case it took up to one day for the emissions to return to normal following a 30 minute complete shutdown of the incinerator and three baghouse systems being tested. Table 9 describes the impact of broken bags on emissions for a typical size baghouse. As emission levels become tighter in attempts to control air toxics, response to broken bags will take on new importance. More importantly, system design changes to promote longer bag life and better emission monitoring will be needed. Once continuous monitoring of outlet particulate is required, the industry will be challenged. Until then it will be business as usual with designs aimed at passing a one time or yearly stack test with the baghouse primed for peak performance. This won`t do much to protect the environment from air toxics to the proposed units.
