Es-1 Doe Has More Than 7,000 Surplus Contaminated Executive Summary - Background DOE HAS MORE THAN 7,0001 SURPLUS CONTAMINATED FACILITIES THAT MAY REQUIRE DECOMMISSIONING, COSTING THE DEPARTMENT MORE THAN $20 BILLION, OR ABOUT 10% OF ITS TOTAL ENVIRONMENTAL CLEANUP LIABILITY.

The term "life cycle cost" refers to the cost to complete the mission of the Environmental Management program. The Ten Year Plan was not finalized at the time of report publication. 1 DOE EM-40 "Decommissioning of Facilities" Web Page (http://www.em.doe.gov/dd/), October 4, 1996. 2 Fernald and Weldon Spring decommissioning cost estimates are included under remedial actions. ES-1 Executive Summary - Background THE PURPOSE OF THIS STUDY IS TO ANALYZE PHYSICAL ACTIVITIES IN FACILITY DECOMMISSIONING AND TO DETERMINE APPROACHES TO IMPROVE THE DECOMMISSIONING PROCESS IN DOE'S ENVIRONMENTAL RESTORATION PROGRAM. Facility Life Cycle Facility Construction Operations Shutdown Deactivation Decommissioning End State Planning Processing Operations cease Decontamination Decontamination Site release Siting Manufacturing System shutdown De-energization Dismantlement Facility reuse Designing Testing Process shutdown Stabilization Demolition Permitting Storage STUDY FOCUS DOE's Office of Environmental Restoration is currently responsible for more than 1,000 facilities and accepts deactivated facilities for decommissioning. Note: DOE decommissioning normally excludes: high level waste tanks, spent nuclear fuel, soil and groundwater remediation, and waste transportation and disposal. ES-2 Executive Summary - Analysis Approach THE STUDY FOCUSED ON QUANTIFYING PRODUCTIVITY OF DECOMMISSIONING PHYSICAL ACTIVITIES AND IDENTIFYING HOW PRODUCTIVITY IS AFFECTED BY SPECIFIC WORKING CONDITIONS.

ES-3 Executive Summary - Analysis Approach THE DECOMMISSIONING BENCHMARKING TEAM FOLLOWED A SEVEN STEP BENCHMARKING PROCESS. Step 4 Measure performance of external partners Step 1 Step 2 Step 3 Step 6 Step 7 Determine which Identify Develop benchmarks Formulate and decommissioning Determine the key implement performance variables benchmark and compare functions to partners performance to recommendations/ benchmark to measure benchmarks measure results Step 5 Measure performance of internal partners Note: An Implementation Plan was developed in late 1995 to initiate the Decommissioning Benchmarking Study Steps 1 and 2 were conducted as part of the Implementation Plan development. ES-4 Executive Summary - Products of the Study THE DECOMMISSIONING BENCHMARKING RESULTS ARE THE FOUNDATION FOR SEVERAL DISTINCT PRODUCTS. Benchmarked Developed unit cost productivity ranges factors to improve cost for physical activities estimating capabilities Decommissioning Benchmarking Study Supported refinement of a Decommissioning Served as integral part Technologies Preferred of Process Alternatives Matrix (PAM) Improvement Goals ES-5 Executive Summary - Conclusion AT THE TASK LEVEL AVAILABLE DATA SHOWS THAT THERE ARE NO PRODUCTIVITY DIFFERENCES BETWEEN FEDERAL AND NON-FEDERAL DECOMMISSIONING PROJECTS.

Decommissioning projects should be planned with measurement objectives in mind to achieve the ability to measure performance. DOE should establish a data collection and reporting protocol for DOE and contractors similar to the functions covered in the benchmark, periodically update average and "best-in-class" productivity rates, and continue to seek input from external partners.

  • Prohibited and Restricted Chemical List
    School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List PROHIBITED AND RESTRICTED CHEMICAL LIST Introduction After incidents of laboratory chemical contamination at several schools, DCPS, The American Association for the Advancement of Science (AAAS) and DC Fire and Emergency Management Services developed an aggressive program for chemical control to eliminate student and staff exposure to potential hazardous chemicals. Based upon this program, all principals are required to conduct a complete yearly inventory of all chemicals located at each school building to identify for the removal and disposal of any prohibited/banned chemicals. Prohibited chemicals are those that pose an inherent, immediate, and potentially life- threatening risk, injury, or impairment due to toxicity or other chemical properties to students, staff, or other occupants of the school. These chemicals are prohibited from use and/or storage at the school, and the school is prohibited from purchasing or accepting donations of such chemicals. Restricted chemicals are chemicals that are restricted by use and/or quantities. If restricted chemicals are present at the school, each storage location must be addressed in the school's written emergency plan. Also, plan maps must clearly denote the storage locations of these chemicals. Restricted chemicals—demonstration use only are a subclass in the Restricted chemicals list that are limited to instructor demonstration. Students may not participate in handling or preparation of restricted chemicals as part of a demonstration. If Restricted chemicals—demonstration use only are present at the school, each storage location must be addressed in the school's written emergency plan. Section 7: Appendices – October 2009 37 School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List Following is a table of chemicals that are Prohibited—banned, Restricted—academic curriculum use, and Restricted—demonstration use only.

Title III of SARA, known as the Emergency Planning and Community Right-to-Act, sets requirements for hazardous chemicals, improves the public’s access to information on chemical hazards in their community, and establishes reporting responsibilities for facilities that store, use, and/or release hazardous chemicals. RQ = Reportable Quantity. An amount entered in this column indicates the substance may be reportable under §304 of SARA Title III. Amount is in pounds, a "K" represents 1,000 pounds. An asterisk following the Reporting Quantity (i.e. 5000*) will indicate that reporting of releases is not required if the diameter of the pieces of the solid metal released is equal to or exceeds 100 micrometers (0.004 inches). TPQ = Threshold Planning Quantity. An amount entered in this column reads in pounds and indicates the substance is an Extremely Hazardous Substance (EHS), and may require reporting under sections 302, 304 & 312 of SARA Title III. A TPQ with a slash (/) indicates a "split" TPQ. The number to the left of the slash is the substance's TPQ only if the substance is present in the form of a fine powder (particle size less than 100 microns), molten or in solution, or reacts with water (NFPA rating = 2, 3 or 4).

Naturforsch. 56b,823-825 (2001); received December 20, 2000 Ammonium Permanganate, Oxidation The oxidation or consecutive ammoxidation reaction of benzyl alcohol with solid ammo­ nium permanganate was studied. The first oxidation step leads to the formation of benzalde- hyde, ammonia, and M n02. The M n02 is present in the system in a colloidal form which facilitates the reaction between aldehyde and ammonia, and this latter reactionthen yields benzonitrile. All these products are formed in a heterogeneous system under relatively mild conditions. The yield of benzaldehyde has an optimum at room temperature and increases with increasing reaction time. At higher temperature(e.g. 80 °C) benzonitrile is formed to­ gether with minor amounts of benzyl benzoate. Introduction the reaction of 1 and solid NH4M n04 beside the Benzyl alcohol and its ring-substituted deriva- inorganic residue. After one hour at 22 °C, only ives can be easily oxidized by various permanga­ the formation of benzaldehyde (2) could be ob­ nates [1-14]. Reaction conditions, such as the na- served, and its yield increased with increasing tem­ jure of the oxidant and the medium, temperature, perature. Benzonitrile (3), however, appeared only lie.
