Item Appendix to Bioaccumulation Testing and Interpretation for the Purpose of Sediment Quality Assessment: Status and Needs - Chemical-Specific Summary Tables(United States Environmental Protection Agency, 2000-02) United States Environmental Protection Agency Office of Water; United States Environmental Protection Agency Office of Solid WasteThe document is an appendix to Bioaccumulation Testing and Interpretation for the Purpose of Sediment Quality Assessment: Status and Needs. It summarizes information on chemical characteristics, including water solubilities, half-lives, and partition coefficients (log Kow and Log Koc); human health concerns; wildlife and aquatic organism partitioning factors; and food chain multipliers. A brief profile of the chemical's toxicity, mode of action, and potential for bioaccumulation is also included. Daily intake levels of concern for the protection of human health were compiled, including estimated values for carcinogenic endpoints (slope factors) and noncarcinogenic endpoints (reference doses) for the oral ingestion exposure pathway, and EPA's carcinogenic classifications are provided. Factors affecting partitioning of the chemical in relation to wildlife and aquatic organisms, food chain multipliers (biomagnification factors), toxic effects and mode of action, and other information were compiled from various sources. Data in the chemical summary tables will be useful in addressing the following issues pertaining to bioaccumulation: What species are potentially available for testing?; How should we account for differential partitioning of bioaccumulative contaminants among tissues?; How can bioaccumulation methods be used to assess population-level effects?; How can tissue-specific residue levels be coupled with chronic toxicity response data to develop dose-response relationships for bioaccumulative contaminants?Item Bioaccumulation Testing and Interpretation for the Purpose of Sediment Quality Assessment: Status and Needs(United States Environmental Protection Agency, 2000-02) United States Environmental Protection Agency Office of Water; United States Environmental Protection Agency Office of Solid WasteThe purpose of this document is to describe existing knowledge on the use of bioaccumulation data as part of sediment quality assessments. This document: Provides a comprehensive summary of existing knowledge on bioaccumulation; Provides a compilation of exposure and effects data for persistent, bioaccumulative chemicals; Discusses factors that affect the bioavailability of sediment-associated contaminants; Identifies how various programs currently use bioaccumulation data for sediment management decisions; Identifies issues and research needs for interpreting bioaccumulation data for the purpose of assessing sediment quality.Item Exemption of Oil and Gas Exploration and Production Wastes from Federal Hazardous Waste Regulations(United States Environmental Protection Agency, 2002-10) United States Environmental Protection Agency Office of Solid WasteThis publication provides and understanding of the exemption of certain oil and gas exploration and production (E&P) wastes from regulation as hazardous wastes under Subtitle C of the Resource Conservation and Recovery Act (RCRA). The information contained within this booklet is intended to furnish the reader with: A basic background on the E&P exemption; Basic rules for determining the exempt or non-exempt status of wastes; Examples of exempt and non-exempt wastes; Status of E&P waste mixtures; Clarifications of several misunderstandings about the exemption.
