The Point Source Inventory is a compilation of the most recent available documented releases of known sediment contaminants from active municipal, industrial, and federal facilities. The major objectives of this inventory and the analysis presented in this report are: Generate a relative of chemicals and industrial categories based on 1993 Toxic Release Inventory (TRI) and 1994 Permit Compliance System (PCS) chemical relase data; prioritize watersheds for collection of additional information that might lead to the identification of additional monitoring needs or pollution prevention opportunies; and establish a baseline to which additional or future inventories can be compared. Chapter 2 of this report describes the data sources used to develop the Point Source Inventory. Chapter 3 describes the data sources, assumptions, and algorithms used to develop the screening-level chemical load scores. Chapter 4 presents a summary of the results in relationship to chemicals and chemical classes, watersheds, and industrial categories. Appendix A contains the data used to develop chemical load scores for individual chemicals. Appendix B presents the results of the watershed priority groupings, and Appendix C includes detailed results of the analysis by industrial category.
