The purpose of this project, which was funded by the California State Water Resources Control Board (SWRCB), was to evaluate the compliance and wetland condition of compensatory wetland mitigation projects associated with Clean Water Act Section 401 Water Quality Certifications throughout California. This was done by selecting, reviewing and performing field evaluations for 143 permit files distributed across the 12 Water Board regions and sub-regions of the State. For each permit file we assessed the extent to which permittees complied with their mitigation conditions, including acreage requirements, whether the corresponding mitigation efforts resulted in optimal wetland condition, and if the habitat acreages gained through compensatory mitigation adequately replaced those lost through the permitted impacts. We found that permittees are largely following their permit conditions (although one-quarter to one-third of the time these are not met), but the resulting compensatory mitigation projects seldom result in wetlands with optimal condition.

Desalination Plant Entrainment Impacts and Mitigation

Raw seawater is used for a variety of purposes, including as source water for desalination plants and to cool coastal power plants. Raw seawater is, however, not just cold and salty but an ecosystem that contains diverse and abundant organisms including the young stages of numerous invertebrates and fishes. Whether impinged (large individuals stuck on screens prior to entering the plant or killed during other plant processes such as heat treatment) or entrained (small individuals carried into the plant with the water) the organisms are killed, essentially eliminating the living production in the water used (review in York and Foster 2005). Considerable research has have been done in California to better estimate losses to this ecosystem by coastal power plant intakes (York and Foster 2005, Steinbeck et al. 2007), and to determine how these losses can be mitigated (Strange et al. 2004). The information from this research has contributed to State of California policy regulating water used by power plants.

Endangered and Threatened Wildlife and Plants; Endangered Species Act Compensatory Mitigation Policy
Federal Register | December 27, 2016...

SUMMARY: We, the U.S. Fish and Wildlife Service (Service or USFWS), announce the final Endangered Species Act (ESA) Compensatory Mitigation Policy. The new policy steps down and implements recent Executive Office, Department of the Interior, and Service mitigation policies that reflect a shift from project-by-project to landscape-scale approaches to planning and implementing compensatory mitigation.

The new policy is established to improve consistency and effectiveness in the use of compensatory mitigation as recommended or required under the ESA. The ESA Compensatory Mitigation Policy covers permittee-responsible mitigation, conservation banking, in-lieu fee programs, and other third-party mitigation mechanisms, and stresses the need to hold all compensatory mitigation mechanisms to equivalent and effective standards.

DATES: This policy is effective on December 27, 2016.

Greenhouse Gas Emissions Calculator for the Water Sector: User’s Manual
Bureau of Reclamation | September 24, 2013...

The Santa Ana Watershed Basin Study (Basin Study) is a collaborative effort by the Santa Ana Watershed Project Authority (SAWPA) and the Bureau of Reclamation (Reclamation), authorized under the Sustain and Manage America's Resources for Tomorrow SECURE Water Act (Title IX, Subtitle F of Public Law 111-11).

The Basin Study complements SAWPA’s Integrated Regional Water Management (IRWM) planning process, also known as their “One Water One Watershed” (OWOW) Plan. It refines the watershed’s water projections, and identifies potential adaptation strategies, in light of projected effects of climate change. The Climate Change Analysis for the Santa Ana River Watershed (SARW) is a contributing section to the Basin Study.

The Greenhouse Gas (GHG) Emissions Calculator was developed as a tool to support the Climate Change Analysis. It was developed to evaluate mitigation strategies, while the Climate Change Analysis focused primarily on adaption and vulnerability analysis. Development of the tool began in 2012 and was completed in August 2013.

This report explains the methods used to develop the calculator and provides instructions on how to use it by introducing examples. The examples focus on the SARW to show how to develop a GHG emissions baseline, evaluate what it would take to meet specific GHG emission reduction goals, and illustrate how the GHG Emissions Calculator can be used to analyze projects.

Chapter 1 provides an introduction to the project, a literature review, and a summary of California’s GHG legislation. The methods used in the GHG Emissions Calculator can be found in Chapter 2. A guide showing users what data is needed and how to enter that data can be found in Chapter 3. Chapter 4 provides an introduction to the SARW, the GHG emission baseline for the SARW, discusses varies scenarios to reduce GHG emissions, and compares those reduction scenarios. In Chapter 5 SAWPA’s 20 finalist for the Integrated Regional Water Management (IRWM) funding were analyzed using the GHG Emissions Calculator.

The GHG Emission Calculator is a decision-making tool that can be used to explore the links between water resources, energy, and GHG emissions. It can be used to determine water supply and energy demands for the study area, in addition to GHG emissions from 1990 to 2050. It can be used to analyze a study area ranging from a city block to an entire watershed, regardless of the level of detailed data available. The GHG Emissions calculator is a vital tool for decision makers when developing water supply plans for the future. It is also equipped to evaluate long term GHG emission reduction potential for new projects that will alter the water supply portfolio.

Mitigation and Fees for the Intake of Seawater by Desalination and Power Plants

Raw seawater is used for a variety of purposes, including as source water for desalination plants and to cool coastal power plants. Raw seawater is, however, not just cold and salty but an ecosystem that contains diverse and abundant organisms including the young stages of numerous invertebrates and fishes. Whether impinged (large individuals stuck on screens prior to entering the plant or killed during other plant processes such as heat treatment) or entrained (small individuals carried into the plant with the water) the organisms are killed, essentially eliminating the living production in the water used (review in York and Foster 2005).

Considerable research has have been done in California to better estimate losses to this ecosystem by coastal power plant intakes (York and Foster 2005, Steinbeck et al. 2007), and to determine how these losses can be mitigated (Strange et al. 2004). The information from this research has contributed to State of California policy regulating water used by power plants. The policy now applies only to power plants but the intent to protect marine organisms is also broadly applicable to desalination plants and other users of large volumes of seawater.

The State’s Once-through Cooling Policy (Policy) states that plants must implement measures to mitigate interim impacts occurring after October 1, 2015, and until the plant comes into full compliance through conversion to closed cycle cooling or by using operational controls and/or structural control technology that results in comparable reductions in impingement and entrainment (IM&E).
