Show agencies to perform a risk assessment and detailed testing each time the facility is operated. The results are found in Tables 14-17. Table 14 Ogden Environmental Services, Inc.

However, the tests indicate that the Destruction and Removal Efficiency criteria are still met for most of the compounds. One compound, SF6, has traditionally given low DREIs, primarily because of its refractory nature with respect to oxidation. Toluene has traditionally been found to be a stable product of reformation( 1) in full-scale hazardous waste combustors. Therefore, it is normally not a good choice as a POHe because credit is not given for destroying the products of reformation when calculating DRE. 1 7 |
