Thus, it does not impose legally binding requirements on EPA, states, municipalities, or the regulated community. The general descriptions provided in this document might not apply to a particular situation based on the circumstances. This document does not confer legal rights or impose legal obligations on any member of the public. Among other things, the document describes existing requirements with respect to industrial dischargers and publicly owned treatment works (POTWs) under the CWA and its implementing regulations at Title 40 of the Code of Federal Regulations, Parts 122, 123, 124, and 403 and chapter I, subchapter N. Although EPA has made every effort to ensure the accuracy of the discussion in this document, a discharger’s obligations are determined, in the case of directly discharging POTWs, by the terms of its National Pollutant Discharge Elimination System permit and EPA’s regulations or, in the case of indirect dischargers, by permits or equivalent control mechanisms issued to POTW industrial users or by regulatory requirements. Nothing in this document changes any statutory or regulatory requirement.

  • Animal Waste and Water Quality: EPA’S Response to the Waterkeeper Alliance Court Decision on Regulation of Cafos
    Animal Waste and Water Quality: EPA’s Response to the Waterkeeper Alliance Court Decision on Regulation of CAFOs Claudia Copeland Specialist in Resources and Environmental Policy November 8, 2011 Congressional Research Service 7-5700 www.crs.gov RL33656 CRS Report for Congress Prepared for Members and Committees of Congress Animal Waste and Water Quality Summary In October 2008, the Environmental Protection Agency (EPA) issued a regulation to revise a 2003 Clean Water Act rule governing waste discharges from large confined animal feeding operations (CAFOs). This action was necessitated by a 2005 federal court decision (Waterkeeper Alliance et al. v. EPA, 399 F.3d 486 (2nd Cir. 2005)), resulting from challenges brought by agriculture industry groups and environmental advocacy groups, that vacated parts of the 2003 rule and remanded other parts to EPA for clarification. The Clean Water Act prohibits the discharge of pollutants from any “point source” to waters of the United States unless authorized under a permit that is issued by EPA or a qualified state, and the act expressly defines CAFOs as point sources. Permits limiting the type and quantity of pollutants that can be discharged are derived from effluent limitation guidelines promulgated by EPA. The 2003 rule, updating rules that had been in place since the 1970s, revised the way in which discharges of manure, wastewater, and other process wastes from CAFOs are regulated, and it modified both the permitting requirements and applicable effluent limitation guidelines. It contained important first-time requirements: all CAFOs must apply for a discharge permit, and all CAFOs that apply such waste on land must develop and implement a nutrient management plan.

  • EPA Regulations: Too Much, Too Little, Or on Track?
    EPA Regulations: Too Much, Too Little, or On Track? James E. McCarthy Specialist in Environmental Policy Claudia Copeland Specialist in Resources and Environmental Policy March 21, 2011 Congressional Research Service 7-5700 www.crs.gov R41561 CRS Report for Congress Prepared for Members and Committees of Congress EPA Regulations: Too Much, Too Little, or On Track? Summary In the two years since Barack Obama was sworn in as President, the Environmental Protection Agency (EPA) has proposed and promulgated numerous regulations implementing the pollution control statutes enacted by Congress. Critics have reacted strongly. Many, both within Congress and outside of it, have accused the agency of reaching beyond the authority given it by Congress and ignoring or underestimating the costs and economic impacts of proposed and promulgated rules. Republican leaders have promised vigorous oversight of the agency in the 112th Congress, and the House has already voted to overturn specific regulations and to limit the agency’s authority. Particular attention is being paid to the Clean Air Act, under which EPA has moved forward with the first federal controls on emissions of greenhouse gases and addressed conventional pollutants from a number of industries. Environmental groups disagree that the agency has overreached, and EPA itself maintains that its pace of regulation under the Clean Air Act is actually slower than the pace during the first years of the Clinton and George W. Bush Administrations. The agency states that critics’ focus on the cost of controls obscures the benefits of new regulations, which, it estimates, far exceed the costs; and it maintains that pollution control is an important source of economic activity, exports, and American jobs.

  • Calculating Water Quality-Based Effluent Limitations for Surface Water Discharges
    BUREAU OF WATER QUALITY PROGRAM GUIDANCE Wastewater Policy and Management Team Wisconsin Department of Natural Resources 101 S. Webster Street, P.O. Box 7921 Madison, WI 53707-7921 Calculating Water Quality-Based Effluent Limitations for Surface Water Discharges 08/10/2020 EGAD Number: 3400-2020-13 This document is intended solely as guidance and does not contain any mandatory requirements except where requirements found in statute or administrative rule are referenced. Any regulatory decisions made by the Department of Natural Resources in any matter addressed by this guidance will be made by applying the governing statutes and administrative rules to the relevant facts. _____________________________________________________________________________________ APPROVED: Adrian Stocks 12/07/2020 _______________________________ __________ Adrian Stocks, Director Date Bureau of Water Quality Summary Section 283.13(5), Wis. Stats., requires that effluent limitations be established in permits for point source discharges to surface water to ensure that applicable state water quality standards are met. These types of effluent limitations are protective of water quality and are referred to as water quality- based effluent limits (WQBEL). The WQBEL calculation process completed by the Wisconsin Department of Natural Resources (the department) involves a site-specific evaluation of the discharge receiving water and effluent characteristics and comparison to state water quality standards. This guidance is intended for use by department staff who are responsible for calculating WQBELs. The document covers how WQBELs are calculated, how staff determine if limits are needed in permits, and how those limits should be expressed in WPDES permits for point source discharges to Wisconsin surface waters. The following guidance documents also provide information on WQBEL calculation procedures and are used by WQBEL calculation staff.

  • Nutrient Water Quality Trading: a Market- Based Solution to Water Pollution in the Natural State*
    Nutrient Water Quality Trading: A Market- Based Solution to Water Pollution in the Natural State* I. INTRODUCTION In the decades since the passage of the Clean Water Act (CWA), our nation’s waters remain impaired by dangerous levels of nutrients such as phosphorous and nitrogen, which can cause serious health impacts.1 Excess nutrients also have a substantial environmental impact on waterbodies,2 which in turn diminishes the recreational value of these resources.3 Efforts to control these nutrient levels place a substantial economic burden on local governments in both providing clean drinking water as well as treating wastewater.4 The CWA’s cooperative federalism approach divides sources of nutrient pollution into * The author thanks Professor Sara Rollet Gosman, and several members of the Arkansas Bar Association Environmental Law Section for their guidance, encouragement, and criticism throughout the drafting of this comment.

  • EPA's Regulation of Coal-Fired Power: Is a “Train Wreck” Coming?
    EPA’s Regulation of Coal-Fired Power: Is a “Train Wreck” Coming? James E. McCarthy Specialist in Environmental Policy Claudia Copeland Specialist in Resources and Environmental Policy August 8, 2011 Congressional Research Service 7-5700 www.crs.gov R41914 CRS Report for Congress Prepared for Members and Committees of Congress EPA’s Regulation of Coal-Fired Power: Is a “Train Wreck” Coming? Summary Given the central role of electric power in the nation’s economy, and the importance of coal in power production, concerns have been raised recently about the cost and potential impact of regulations under development at the Environmental Protection Agency (EPA) that would impose new requirements on coal-fired power plants. Six of the rules, which have drawn much of the recent attention, are Clean Air Act regulations. Two others are Clean Water Act rules, and one is a Resource Conservation and Recovery Act rule. The majority are expected to be promulgated over the next 18 months. All together, these rules have been characterized by critics as a regulatory “train wreck” that would impose excessive costs and lead to plant retirements that could threaten the adequacy of electricity capacity (i.e., reliability of supply) across the country, especially from now through 2017. Although some question why EPA is undertaking so many regulatory actions in such a short time- frame, supporters of the regulations assert that it is decades of regulatory delays and court decisions that have led to this point, resulting in part from special consideration given electric utilities by Congress under several statutes. Further, several of the current regulatory developments have been under consideration for a decade or longer, or are being reevaluated after an earlier action was vacated or remanded to EPA by the courts.
