Chapter 1
Introduction
Publication: Total Maximum Daily Load Development and Implementation: Models, Methods, and Resources
Abstract
The 1972 US Clean Water Act (CWA) as amended in 1977, 1987, and 2000, requires that all states, territories, and approved tribes to biennially list all waterbodies or specific segments of waterbodies that fail to meet jurisdictional water quality standards. An approved total maximum daily load (TMDL) document is a set of actions designed to restore water to as close to its pristine quality as required to meet the prevailing water quality standards, by examining water quality problems, identifying sources of pollutants, and specifying actions that solve the problem. The TMDL process provides for nonpoint source control tradeoffs. The CWA was amended to support updated water quality standards for monitoring of pathogen indicators in recreational waters. An implementation plan is nonetheless recommended to be submitted so that watershed management, monitoring, logistics, and operations can be documented. This chapter also presents an overview on the key concepts discussed in this book.
