ABSTRACTThe state has the power both to enable local communities to regulate land usage, as well as to override local jurisdictions' zoning policies. In Massachusetts, two pieces of legislation have empowered the state to override local land use control for the purpose of constructing two types of facilities: low and moderte income housing and hazardous waste treatment facilities. Both initiatives have stimulated considerable debate and controversy. This paper provides a framework or "test" for understanding the relative appropriateness of state overrides in general. In addition, the two Massachusetts case are discussed and analyzed according to these criteria.

Chemical alternatives assessment is a method rapidly developing for use by businesses, governments, and nongovernment organizations seeking to substitute chemicals of concern in production processes and products. Chemical alternatives assessment is defined as a process for identifying, comparing, and selecting safer alternatives to chemicals of concern (including those in materials, processes, or technologies) on the basis of their hazards, performance, and economic viability. The process is intended to provide guidance for assuring that chemicals of concern are replaced with safer alternatives that are not likely to be later regretted. Conceptually, the assessment methods are developed from a set of three foundational pillars and five common principles. Based on a number of emerging alternatives assessment initiatives, in this commentary, we outline a chemical alternatives assessment blueprint structured around three broad steps: Scope, Assessment, and Selection and Implementation. Specific tasks and tools are identified for each of these three steps. While it is recognized that on‐going practice will further refine and develop the method and tools, it is important that the structure of the assessment process remain flexible, adaptive, and focused on the substitution of chemicals of concern with safer alternatives.
