In accordance with the requirements of the Massachusetts Contingency Plan (MCP) in 310 CMR 40.0834, this Phase IIA SOW describes Foster Wheeler and the Joint Defense Group's approach to the proposed environmental investigation and is being submitted to the Massachusetts Department of Environmental Protection (DEP) for approval. The Phase IIA SOW is the first task of a Phase II investigation and is intended to collect initial groundwater information and additional site data to partially fulfill the requirements in 310 CMR 40.0835. The property known as the Fireworks Site (Site) is comprised of approximately 240 acres, portions of which have a history of the use, storage, and disposal of potentially hazardous materials associated with the manufacture and research of munitions and pyrotechnics. A USGS map showing the location of the Site is included as Figure 1. This Phase IIA SOW was developed to address the technical complexities associated with this Site, its large size, and various historical uses in a phased investigation, ultimately leading to completion of a Phase II Comprehensive Site Assessment. The technical approach is designed to develop an understanding of groundwater flow and quality on site and provide more specific hydrogeochemical data at several areas of interest identified by the DEP and in the Phase I Initial Site Investigation Report completed by Foster Wheeler (Foster Wheeler, 1997). Based on the foregoing, the intent of this investigation is to provide groundwater data that can be used in conjunction with data obtained from previous investigations to further determine or evaluate Site Hydrogeological Characteristics, Environmental Fate and Transport of Oil and/or Hazardous Material (OHM) and the Nature and Extent of Contamination pursuant to the requirements of a Phase II Report (310 CMR 40.0835[d-fj). Subsequent to this work, additional environmental investigations may be defined and conducted during one or more successive phases of the Phase II process. The format of this Phase IIA SOW includes Section 1.0 (this section), which describes the objectives of and general approach to this investigation as well as the organization of this Phase IIA SOW. Section 2.0 summarizes current site conditions and site history, and provides an overview of previous site assessment work under the MCP and the intended purpose of the Phase IIA investigation. Section 3.0 describes the field investigation for the groundwater monitoring program. Section 4.0 briefly discusses the format and content of the Phase IIA report or data submittal (the work products of this investigation). Section 5.0 briefly discusses public involvement. Sections 6.0 and 7.0 describe the Foster Wheeler project organization and the anticipated schedule for completion of project activities, respectively. Specific quality assurance (QA) procedures to be implemented during data collection activities are described in the QA Plan (QAP), included in Appendix A. Site specific health and safety procedures are included in the Health and Safety Plan (HASP) in Appendix B. 2.0 MCP INVESTIGATION HISTORY AND PROCESS 2.1 Phase I Investigation and Tier Classification In October 1995, after conducting surface water, sediment, and fish tissue sampling for mercury, lead, and other metals, DEP issued Notices of Responsibility (NORs) to Kerr-McGee Chemical Corporation, Massachusetts Institute of Technology, National Coating Corporation, Susquehanna Corporation and the U.S. Department of Defense based on their alleged status as either owners, operators, generators, 0198.236 I 10/2/8 IsI --- £ OFSIT so I FAREA ____S__ TEBOUNDARY-,; my SIT- L-C--I---A- - 7 n F SRWORSST 1000 0 2000 2000 3000 4000 SCALE IN FEET - SCALE: AS SHOWN Sourc: USGS 7.5 Miln Topographic Maps; Whitman, MA, 1977, and Hanover.

  • Hydrazine Chemical Abstracts Service Registry Number 302-01-2
    Screening Assessment for the Challenge Hydrazine Chemical Abstracts Service Registry Number 302-01-2 Environment Canada Health Canada January 2011 Screening Assessment CAS RN 302-01-2 Synopsis The Ministers of the Environment and of Health have conducted a screening assessment of hydrazine, Chemical Abstracts Service Registry Number 302-01-2. The substance hydrazine was identified in the categorization of the Domestic Substances List as a high priority for action under the Chemicals Management Plan Challenge initiative. Hydrazine was identified as a high priority as it was considered to pose an intermediate potential for exposure of individuals in Canada and is classified by other agencies on the basis of carcinogenicity. The substance did not meet the ecological categorization criteria for persistence or bioaccumulation potential, but it did meet the criteria for inherent toxicity to aquatic organisms. Most hydrazine is imported into Canada in aqueous solutions, the form of the product commonly found on the market. In aqueous solution, all the hydrazine is invariably present as the hydrate. This chemical species has a molecule of water loosely attached to an electronegative nitrogen atom by a weak hydrogen bond. The hydrated form is not considered to be chemically different from the anhydrous substance, and can be considered to represent a mixture of the substance with water. Therefore, this assessment considers that hydrazine and hydrazine hydrate are effectively the same substance. Only minor differences in physical-chemical properties are observed between these two forms due to the association of hydrazine with water in the hydrated form. According to information submitted under section 71 of CEPA 1999, hydrazine was not manufactured by any company in Canada in the calendar year 2006 above the 100 kg reporting threshold.

  • Chapter 8.0 Chemical and Process Safety. Non-Sensitive Version
    8.0 CHEMICAL AND PROCESS SAFETY 8.1 CONDUCT OF REVIEW This chapter of the revised Draft Safety Evaluation Report (revised DSER) contains the staff’s review of chemical and process safety described by the applicant in Chapter 8 of the revised Construction Authorization Request (revised CAR) (Reference 8.3.19), with supporting process safety information from Chapters 5 and 11 of the revised CAR. The objective of this review is to determine whether the chemical process safety principal structures, systems, and components (PSSCs) and their design bases identified by the applicant provide reasonable assurance of protection against the consequences of potential accidents. The staff evaluated the information provided by the applicant for chemical process safety by reviewing the revised CAR, supplementary information provided by the applicant, and relevant documents available at the applicant’s offices but not submitted by the applicant. The staff also reviewed technical literature as necessary to understand the process and safety requirements. The review of aqueous polishing (AP) and mixed oxide process (MP) safety design bases and strategies was closely coordinated with the review of the radiation and chemical safety aspects of accident sequences described in the Safety Assessment of the Design Bases (see Chapter 5.0 of this revised DSER), the review of fire safety aspects (see Chapter 7.0 of this revised DSER), and the review of plant systems (see Chapter 11.0 of this revised DSER). The staff reviewed the chemical process and safety information in the revised CAR and supporting documents against the following regulations: ! Section 70.23(b) of 10 CFR states, as a prerequisite to construction authorization, that the design bases of the PSSCs and the quality assurance program be found to provide reasonable assurance of protection against natural phenomena and the consequences of potential accidents.

These materials may replace the presently used explosives, sooner or later. In this review, the authors try to explore some of these materials viz., polynitropolycyclic cage explosives, cyclic nitramines, cage explosives, nitro derivatized heterocyclic compounds, nickel hydrazine nitrate (NHN) complex, nitrocubanes, hafnium explosives, heat-resistant explosives, new insensitive high explosives and some other novel high energetic materials. There is a need for the development of analytical methods for identification of these materials and their post explosion residues as these are likely to be encountered in crimes. 1.
