"With the passage of the Frank R. Lautenberg Chemical Safety for the 21st Century Act on June 22, 2016, the main body of chemical management law in the United States changed dramatically. This guide summarizes the new law, highlights the changes that will have the greatest impact, and offers pertinent analysis on the implementation of the new law."--

Prompted by important developments that have occurred since the publication of the third edition eight years ago, the newly updated TSCA Handbook provides anyone who manufactures, processes, distributes, or uses chemicals with a comprehensive look at their requirements under the Toxic Substances Control Act (TSCA). Practical and informative, this ready reference details current regulation under TSCA. It examines the Environmental Protection Agency's program for evaluation and regulating new substances, and it discusses PMN preparations and follow through, inspections and audits, and more. Developments addressed in this edition include the following: changes to the Inventory Update Rule, new voluntary testing initiatives, new enforcement policies and rules, revised PCB regulations regarding contaminated sites, and increased maximum civil penalties.

Systematic review - a scientific investigation that focuses on a specific question and uses explicit, prespecified scientific methods to identify, select, assess, and summarize the findings of similar but separate studies - has become the foundation for assessing evidence to be used for decision making in a variety of health contexts, including health care and public health. At the request of the Environmental Protection Agency (EPA), this publication reviews EPA's 2018 guidance document Application of Systematic Review in TSCA (Toxic Substances and Control Act) Risk Evaluations and associated materials to determine whether the process is comprehensive, workable, objective, and transparent.

This text is divided into three parts. The first part describes basic toxicological concepts and methodologies used in aquatic toxicity testing, including the philosophies underlying testing strategies now required to meet and support regulatory standards. The second part of the book discusses various factors that affect transport, transformation, ultimate distribution, and accumulation of chemicals in the aquatic environment, along with the use of modelling to predict fate.; The final section of the book reviews types of effects or endpoints evaluated in field studies and the use of structure-activity relationships in aquatic toxicology to predict biological activity and physio-chemical properties of a chemical. This section also contains an extensive background of environmental legislation in the USA and within the European Community, and an introduction to hazard/risk assessment with case studies.

The Toxic Substances Control Act (TSCA) was signed into law on October 11, 1976 by President Ford giving the EPA new regulatory authority while also implementing the transformation of nonregulated sectors of the chemical industry to regulated ones. This guidebook gives guidance to the smaller and medium-sized chemical industry manufacturers, processors, formulators, and users.
