RCRA trial burns have been satisfactorily completed with GB for LIC- 1 and LIC-2, the MPF, and the DFS. The TSCA trial burn for the DFS had to be redone, however, which delayed the processing of M55 rockets.

From page 15... ...
In actuality, after about one-third of the rockets (11,592 units) had been processed, rocket processing was stopped because some of the exhaust gas samples collected during the first TSCA trial burn contained a specific polychlorinated biphenyl (PCB)

. Once the surrogate trial burns demonstrated that the incinerators met the Army's performance standards, chemical agent trial burns were conducted to satisfy RCRA and TSCA requirements.

Results of Surrogate Trial Burns The TOCDF operates under RCRA permit UT5210090002 issued by the state of Utah. Under the requirements of this permit, the incinerator systems must demonstrate that they meet performance standards that ensure effective and safe destruction of chemical agents before beginning routine operations.

The Army's 99.9999 percent DRE requirement was also demonstrated. Hence, the MPF surrogate trial burns demonstrated that the system could safely proceed to the second phase of the RCRA demonstration and testing requirements the chemical agent trial burn (ATE)

Measurement method detection limits were above the equivalent HRA emission rates for dimethylphthalate, however, so conclusions cannot be drawn about the relation of actual and projected emissions for this SVOC. The list in Table 2-5 includes compounds for which a measured emission rate from LIC-1 or LIC-2 was higher than the value used in the HRA or for which the detection limit was too high to draw a meaningful conclusion.

The PQL is 3.3 times the detection limit. bThe highest concentrations measured during the initial JACADS trial burns were used by the State of Utah DSHW to estimate TOCDF .

The measured emission rates or detection limits for the other VOCs and SVOCs were below those used in the HRA or were not detected at all. Table 2-7 lists compounds for which measured emission rates or detection limits from the DFS were higher than the value used in the HRA.

The detection limits for four SVOCs and 12 VOCs were too high to verify that the maximum emission rates were lower than the assumed HRA emission rate. Table 2-9 lists compounds for which measured emission rates or detection limits from the MPF were higher than the values used in the HRA.

Confidence limits set the bounds of expected long-term emissions performance; tolerance limits set the bounds of selected future emission rates. 27 TABLE 2-10 Trial Burn Results for DFS PCB DREs Run Number PCB Train PCDD/F Train January 1997 > 99.999973 > 99.999596 > 99.999795 Average 2 3 Average > 99.999783 November 1998 > 99.999986 > 99.999986 > 99.999984 > 99.999985 > 99.999950 > 99.999949 > 99.999940 > 99.999946 Source: Adapted from EG&G, 1997d; Holmes, 1999.

Consequently, on December 23, 1998, the facility was authorized to process rockets at a rate equal to one-half the rate demonstrated during the November trial burn. IMPROVING MONITORING SYSTEMS FOR AGENTS AND NONAGENTS Background In 1994, after reviewing monitoring systems for the detection and quantification of chemical agents and the by-products of agent and nonagent destruction at JACADS and proposed for the TOCDF, the Stockpile Committee issued the Review of Monitoring Activities Within the Army Chemical Stockpile Disposal Program (NRC, 1994b)

These units are currently being used to identify interferant compounds that trigger false positive ACAMS alarms so that they can be eliminated from the plant and/or exhaust stream. A GC-MSD unit with a parallel atomic emission detector designed to recognize phosphorus and sulfurcontaining compounds that can trigger the ACAMS flame photometric detectors has been developed and is being tested at CAMDS.

From page 30... ...
Detection limits in the initial field trial at CAMDS, which were affected by the cleanliness of the multipass mirrors and their alignment, were significantly worse than the laboratory values. A second field trial designed to test the feasibility of detecting both agent and products of incomplete combustion in exhaust gases from the CAMDS incinerator stack was unsuccessful because of spectral interference from the high concentration of water vapor in the exhaust samples (Stedman and McLaren, 1996)
