Alternating schedule defined

Recommendation 2. The end state, end use, and stewardship issues pertaining to closure of any chemical agent disposal facility should be resolved early so that planning can proceed on an assured rather than an assumed basis. If possible, facility end uses should be included in the RCRA operating permit. If end use and end state cannot be defined early in the planning process, risk assessments and cost and schedule estimates for alternative end states and uses should be prepared. 

The Feasibility Test" being conducted must demonstrate for success that a market may be established for the raw material that competes with the alternative uses or disposition of the material. This market will define a schedule of raw material prices such as is indicated by Table III. At the same time, a successful test result will demonstrate that the product densified fuel competes with alternative fuels, establishing a product sales price on the order of the Table IV invitation. Between these schedules, there must be the money to accomplish the physical processing and attract the financing. The "test" is not to presume either of these schedules, but to demonstrate the three-fold mutual benefit 1)... 

The safety assessment now follows a procedure which starts with the calculation of the steady state values for ln(Da ) based on the production requirements for Xs and Ts and the kinetic parameters E/R and n, which must be known. The plausibility of this value may be checked by using the scheduled residence time, the frequency factor and the feed concentration Cgj for an alternative determination, which must result in an identical value. This step is followed by the determination of P using Equ. (4-122) and the known process and plant data. If the point defined by P and ln(Daco) is above the limit curve in the nomogram for the corresponding Stanton munber, the operating point is safe under normal operating conditions. 

Informal and formal trade-off analysis objectives, execution, data collection requirranmts, schedule of activities, analysis of results, and expected outcomes need to be fully defined. Each trade-off analysis is conducted for the purpose of selecting among competing alternatives to support customer needs, system effectivraiess, design-to-cost, or life cycle cost objectives within acceptable levels of risk.
