  • Hazardous Waste: Industrial Waste Requirements
    ENVIRONMENT, SAFETY & HEALTH DIVISION Chapter 17: Hazardous Waste Industrial Waste Requirements Product ID: 182 | Revision ID: 2413 | Date published: 26 May 2021 | Date effective: 26 May 2021 URL: https://www-group.slac.stanford.edu/esh/eshmanual/references/hazwasteReqIndustrial.pdf 1 Purpose The purpose of these requirements is to ensure that industrial wastes are safely managed. They cover characterization, containment, handling, labeling, tracking, and disposal. They apply to workers (as hazardous waste generators and custodians), field construction managers, supervisors, line management, the hazardous waste program manager; and Fleet Services, Facilities and Operations, and Waste Management. 2 Requirements All industrial waste, defined as waste that contains hazardous materials but in concentrations below regulatory thresholds (typically demolition debris and contaminated soil), must be tracked by Waste Management and managed according to the requirements below. 2.1 Waste Characterization Because the concentration of contaminants in industrial waste falls below certain regulatory thresholds, it does not need to be managed the same as hazardous waste. (See Hazardous Waste: Waste Determination and Characterization Guidelines.) Indicators that a waste is industrial include the following: . Waste type. Certain types of waste are known to be classified as industrial waste, such as treated wood; soils contaminated with non-hazardous or low levels of polychlorinated biphenyls (PCBs), metals and petroleum hydrocarbons; non-friable asbestos waste; and concrete slurry. In many cases, these wastes result from construction-related projects under the purview of the Facilities and Operations Division. Such operations include excavations, maintenance, remodeling, and building demolition. Waste generation history. The waste generator’s process knowledge of the waste stream can help identify the proper waste category.

  • EPA's Guide for Industrial Waste Management
    Guide for Industrial Waste Management Protecting Land Ground Water Surface Water Air Building Partnerships Introduction EPA’s Guide for Industrial Waste Management Introduction Welcome to EPA’s Guide for Industrial Waste Management. The pur- pose of the Guide is to provide facility managers, state and tribal regulators, and the interested public with recommendations and tools to better address the management of land-disposed, non-haz- ardous industrial wastes. The Guide can help facility managers make environmentally responsible decisions while working in partnership with state and tribal regulators and the public. It can serve as a handy implementation reference tool for regulators to complement existing programs and help address any gaps. The Guide can also help the public become more informed and more knowledgeable in addressing waste management issues in the community. In the Guide, you will find: • Considerations for siting industrial waste management units • Methods for characterizing waste constituents • Fact sheets and Web sites with information about individual waste constituents • Tools to assess risks that might be posed by the wastes • Principles for building stakeholder partnerships • Opportunities for waste minimization • Guidelines for safe unit design • Procedures for monitoring surface water, air, and ground water • Recommendations for closure and post-closure care Each year, approximately 7.6 billion tons of industrial solid waste are generated and disposed of at a broad spectrum of American industrial facilities. State, tribal, and some local governments have regulatory responsibility for ensuring proper management of these wastes, and their pro- grams vary considerably. In an effort to establish a common set of industrial waste management guidelines, EPA and state and tribal representatives came together in a partnership and developed the framework for this voluntary Guide.

  • Step 1: Evaluate Waste (W-Hw1-01)
    www.pca.state.mn.us Evaluate Waste Step 1 in the 10 Steps to Hazardous Waste Compliance series Every business and government agency creates waste. Improperly managed waste can create risks to human health and the environment. Certain wastes pose greater human health or environmental risks due to their chemical properties; these wastes are called hazardous wastes. Businesses and government agencies that create hazardous wastes are called generators of that waste. In Minnesota, the Minnesota Pollution Control Agency (MPCA) and the metropolitan counties of Anoka, Carver, Dakota, Hennepin, Ramsey, Scott, and Washington (Metro Counties) regulate the management of hazardous wastes generated by businesses and government. What is a waste? The hazardous waste requirements apply only to wastes. A waste is a material that is unusable for its intended purpose, discarded, or intended to be discarded. Products that will be used for their intended purpose are not subject to the hazardous waste requirements. How do I know which wastes are hazardous? You must assume that any waste you generate that could reasonably be a hazardous waste is hazardous unless you document that the waste is exempt or non-hazardous. The process of researching and documenting that a waste is non-hazardous is called evaluation. To evaluate a waste as non-hazardous, you must document that it is both not Listed and not Characteristic. · Listed means that the chemical name of the waste or its ingredients meets the definitions found in the F, K, P, or U-list or is a regulated polychlorinated biphenyl (PCB). · Characteristic means that the waste displays any of the chemical characteristics of Ignitability, Oxidizers, Corrosivity, Reactivity, Toxicity, or Lethality.

  • What Is a Rcra Hazardous Waste?
    3105.9002 APPENDIX A.7: WHAT IS A RCRA HAZARDOUS WASTE? Definition of a Solid Waste • A solid waste is any material that is discarded or disposed; a solid waste does not need to be solid; it may be semi-solid, liquid, or even a contained gaseous material. • A material is discarded when it is -- Abandoned (e.g., disposed of, burned or incinerated, or treated before or in lieu of being abandoned). -- Recycled (in a manner constituting disposal, burned for energy recovery, reclaimed, or accumulated speculatively). -- Considered inherently waste-like (like F020-F023, F026 and F028). • EPA has developed product-like/waste-like distinctions for determining which recycled materials are wastes and which are raw materials. • Under EPA’s “contained-in” interpretation, ground water and soils are not considered solid wastes because they are not “discarded” in the sense of being abandoned, recycled, or inherently waste-like. Exceptions to the Definition of Solid Waste (40 CFR 261.2) • Materials used or reused as ingredients in an industrial process to make a product, provided the materials are not being reclaimed. • Materials used or reused as effective substitutes for commercial products. • Materials returned to the original process from which they are generated, without first being reclaimed. Exclusions from the Definition of Solid Waste (40 CFR 261.4) • Domestic sewage and any mixture of domestic sewage and other wastes that pass through a sewer system to a POTW. • Industrial wastewater discharges regulated under the Clean Water Act. • Irrigation return flow. • Nuclear materials, or by products, as defined by the Atomic Energy Act of 1954.

  • 7 Regulations Governing Agricultural Use of Municipal Wastewater and Sludge
    7 Regulations Governing Agricultural Use of Municipal Wastewater and Sludge Government regulations at both the federal and state levels develop within a complex set of circumstances. To fully understand them, regulations must be examined in terms of the regulatory approach taken, the underlying scientific principles that are applied, the objectives of the regulation, and the effectiveness of implementation. The following section begins with a discussion of the regulatory background for agricultural use of municipal wastewater and sludge. Current federal standards for control of pathogens and toxic chemicals in sludge use are then described and evaluated. Finally, state regulations and United States Environmental Pro-tection Agency (EPA) guidelines for agricultural irrigation with treated effluents are discussed. The implementation of wastewater and sludge reuse programs also involves other reg-ulatory components, including program management, surveillance, and enforcement. Economic considerations, liability issues, and public concerns will likewise play a role. These imple-mentation issues are considered in Chapter 8. REGULATORY BACKGROUND Agricultural Irrigation With Wastewater Irrigation of crops with treated effluent and farmland application of sewage sludge have been conducted without federal regulations for decades in the United States. Early regulations by states addressed infectious disease transmission and the reduction of odor. Wastewater irrigation continues to be regulated at the state level, and those states (such as Arizona, Cal-ifornia, Florida, Hawaii, and Texas) that have active water reuse programs have developed comprehensive, numerical water quality criteria for different water uses, including crop irrigation. Pathogen reduction continues to be the major concern, and microbiological limits for treated effluents are based largely on practical experience within the public health community, and on the expected performance of wastewater treatment processes.
