The Department of Toxic Substances Control (DTSC) of the State of California Environmental Protection Agency is in the process of complying with the Regulatory Structure Update. The Regulatory Structure Update is a comprehensive review and refocusing of California's system for identifying and regulating management of hazardous wastes. As part of this effort, the DTSC proposes to change its current waste classification system that categorizes wastes as hazardous or nonhazardous based on their toxicity. Under the proposed system there would be two risk-based thresholds rather than the single toxicity threshold currently used to distinguish between the wastes. Wastes that contain specific chemicals at concentrations that exceed the upper threshold will be designated as hazardous; those below the lower threshold will be nonhazardous; and those with chemical concentrations between the two thresholds will be "special" wastes and subject to variances for management and disposal. The proposed DTSC system combines toxicity information with short or long-term exposure information to determine the risks associated with the chemicals. Under section 57004 of the California Health and Safety Code, the scientific basis of the proposed waste classification system is subject to external scientific peer review by the National Academy of Sciences, the University of California, or other similar institution of higher learning or group of scientists. This report addresses that regulatory requirement.

TRB's Airport Cooperative Research Program (ACRP) Synthesis 22: Common Airport Pavement Maintenance Practices explores how airports implement a pavement maintenance management program, including inspecting and tracking pavement condition, scheduling maintenance, identifying necessary funds, and treating distresses in asphalt and concrete pavements.

This book argues that the appropriate application of the principles and practices of corporate governance to organisational portfolio, program, and projects (‘3P’) governance brings about highly engaged, knowledgeable, and effective governance practices, which in turn substantially improves business case success. The book addresses all three layers of portfolio, program, and project within an integrated governance framework, and it answers the fundamental questions everyone involved in 3P governance must address: What governance structures (processes, functions, roles, responsibilities) need to be in place to ensure optimal portfolio investment outcomes? How do I know our portfolios, as structured, will deliver expected benefits and value? What should senior management be doing, acting in their portfolio governance roles, to deliver great portfolio outcomes? The book introduces and describes a number of important frameworks and models, designed not just for their practical application, but also to be easily comprehended by senior executives not comfortable with traditional ‘project speak’.

"TRB's Airport Cooperative Research Program (ACRP) Report 90: Impact of Regulatory Compliance Costs on Small Airports explores the cumulative costs of complying with regulatory and other federal requirements at small hub and non-hub airports."--Publisher's description.

Data obtained by population based cancer registries have a pivotal role in cancer control. Now also available in Spanish and French, this volume, which contains 15 authored chapters and four useful appendices, remains a standard reference for those planning to establish new cancer registries and those keen to adopt recognized methodologies. Information is given on the techniques required to collect, store, analyse and interpret data.

"TRB's Airport Cooperative Research Program (ACRP) Report 75: Airport Leadership Development Program is designed to assist existing and future airport leaders to assess, obtain, and refine airport-industry leadership skills. The program includes forms for a full 360-degree individual assessment of core leadership traits. A complete facilitator guide with Microsoft PowerPoint presentations and participant workbooks and materials are also included on the CD-ROM that accompanies the print version of the report. The CD-ROM is also available for download from TRB's website as an ISO image. Links to the ISO image and instructions for burning a CD-ROM from an ISO image are provided below."--Publication info.
