CANCELLATION ANALYSIS: DTC Test 70-10

 

DTC Test 70-10 was originally designed to gather data to quantify how much nerve agent vapor and/or aerosol would be removed from the air by soil and vegetation, over time.1 Open air testing was cited as necessary to gather data on the affect of air movement that could not be simulated in then-available enclosed chambers.2 Program delays pushed scheduling of the test into early FY 72.3 Meanwhile, between August 1969 and September 1970, the Dayton Laboratory Division of Monsanto Research Corporation4 collected, evaluated and summarized all available information on the affect of vegetation on nerve agent vapor/aerosol concentration.5 By the March 1971 Deseret Test Center Annual Report of Joint Operational Activities, the fully envisioned test was approved for planning, but execution was indefinitely deferred.6 At the same time, the FY 72 Program Plan listed the test as a 'technical investigation'7 rather than an operational test, projecting that it would cost approximately $290,000 (both FY 72 and total)8 and be completed sometime in FYs 71 or 72.9 Discussions at the annual joint planning conference three months later confirmed that the test had been 'carried over' to the FY 72 program.10 However the test was not listed in the report of conference proceedings as fulfilling any established requirements.11 When the test's Phase I test plan12 was published in June 1971, the test objective had been reduced to gathering data only on the ability of soil to scavenge nerve agent vapors and/or aerosols from the air.13 By the next year's annual planning conference, the only mention of the test is in a table height=400px that indicated that the Phase I laboratory-based work was in progress.14 As of the January 1973 semiannual status report, the laboratory testing had been suspended. The semiannual status report also indicated that a test status report had been published in November 1972. 15,16The next month, the FY 75 outline plan presented an updated collection of validated chemical/biological knowledge requirements that did not include a requirement for data collection on sorption of nerve agents by either soil or vegetation.17 The Deseret Test Center, headquartered at Fort Douglas, Utah, closed in 1973 before approval to conduct the non-laboratory phases of DTC Test 70-10 was obtained; the test is therefore presumed to have been cancelled.

7 A technical investigation was defined as a detailed evaluation of a joint CINC/Service requirement that did not involve the use of large amounts of actual warfare agents or munitions; would often be conducted with simulants and normally within the boundaries of a military installation while conforming to field requirements and conditions. [DTC Program for FY 72, March 1971, page 75.]
8 For reference purposes, DTC 69-14, an operational test, was estimated in the same reference to have FY 72 costs of $800,000 and total costs of $2.5 million. [Ibid., page 2.]

12 Phase I would consist of laboratory trials of sorptivity; Phase II would study sorptivity in a wind tunnel; Phase III would be a field test to confirm data collected in Phases I and II. [DTC Test 70-10 Test Plan, Phase I, June 1971, pages 1-1 and 1-2.]
