USEPA CADDIS (Causual Analysis/Diagnosis Decision-making System) evaluations in aquatic systems
The Causal Analysis/Diagnosis Decision Information System, or CADDIS, is a website developed to help scientists and engineers in the Regions, States, and Tribes conduct causal assessments in aquatic systems. It is organized into five volumes. Vol 1: Stressor Identification provides a step-by-step guide for identifying probable causes of impairment in a particular system, based on the U.S. EPA's Stressor Identification process. Vol 2: Sources, Stressors & Responses provides background information on many common sources, stressors, and biotic responses in stream ecosystems. Vol 3: Examples & Applications provides examples illustrating different steps of causal assessments. Vol 4: Data Analysis provides guidance on the use of statistical analysis to support causal assessments. Vol 5: Causal Databases provides access to literature databases and associated tools for use in causal assessments.

Environmental Trading Network
The ETN is dedicated to sharing information related to the development and implementation of successful water quality trading programs and other market-based strategies for achieving healthy, sustainable ecosystems. It is the only national clearinghouse for key policy and regulatory issues, and transferable water quality trading program design elements. The ETN is an international clearinghouse for information on water quality trading projects and other environmental markets. The ETN has led or participated in a variety of market-based environmental market projects since its inception. In the Great Lakes, these projects focused on issues of water quality and water quantity and how markets or market-like mechanisms could be used to help maintain the balance between use and protection of the resource (see Water Quality Trading and Water Quantity Management). More recently, it has primarily focused on accumulating and posting up-to-date information that is relevant to water quality trading program development in the U.S. and internationally. High level information is also posted for other environmental markets focused on wetland and habitat banking including current information on credit stacking.

State Water Programs: Nutrient Reduction Programs and Methods
Reduction of nutrient impairments to our nation’s waters is a top priority for states and interstates. As discussed in detail in the Executive Summary & Overview below, ACWA has a long history of working with the U.S. Environmental Protection Agency (“EPA”) on strategies to reduce nitrogen and phosphorus loadings to waterbodies. EPA has continued to emphasize the importance of state adoption of numeric nutrient criteria (“NNC”) as the most effective mechanism for ensuring accountable and verifiable reductions. However, states have long advanced that reductions also are being achieved via a rich mosaic of approaches that vary by state, pollutant of concern, sources, and collaborators. This report provides a high level summary of each state’s current approach to nutrient reduction. This report’s methodology, which was conducted in phases of survey, narrative drafting, and state review, is described below. We are pleased that this report consists of responses from every state and the District of Columbia [hereinafter “state(s)”].

Nonpoint Source Program
Established by Section 319 of the Clean Water Act, requires States and U.S. territories to identify navigable waters that cannot attain water quality standards without reducing nonpoint source pollution and develop management plans to reduce nonpoint source pollution; Section 319 of the Clean Water Act (CWA) [Public Law 100‐4, February 4, 1987] directed the Governor of each state to prepare and submit a Nonpoint Source Assessment Report and Nonpoint Source Management Plan for reduction and control of pollution from nonpoint sources to navigable waters in the State; Louisiana Revised Statute 30:2011, signed by the Governor in 1987 as Act 272, instructed Louisiana Department of Environmental Quality, designated at the Lead Agency for the state’s Nonpoint Source Program, to develop and implement a NPS Management Program. The NPS Management Program is to be developed in coordination with appropriate state agencies, including, but not limited to, the Department of Natural Resources, the Department of Wildlife and Fisheries, the Department of Agriculture and Forestry, and the State Soil and Water Conservation Committee in those areas pertaining to their respective jurisdictions (La.R.S. 30:20).
