US Environmental Legislative Process Overview

Federal House or Senate Bill Federal Act Federal Regulations Federal Rules or Guidelines State Bill State Act State Rules or Guidelines Regional or Local Ordinance Local Regulations Local Rules or Guidelines

Resource Conservation and Recovery Act

– Goals • To protect human health and the environment from the potential hazards of waste disposal • To conserve energy and natural resources • To reduce the amount of waste generated • To ensure that wastes are managed in an environmentally sound manner.

Subtitle C and D

  Subtitle C – Hazardous Waste Management – Establishes a federal program to manage hazardous wastes from cradle to grave to ensure that hazardous waste is handled in a manner that protects human health and the environment. Subtitle D – Solid Waste Management – Focuses on state and local governments as the primary planning, regulating, and implementing entities for the management of nonhazardous solid waste

A waste is “a discarded material including solid, liquid, semisolid (sludge) or contained gaseous material.” May 19, 1980 Federal Register.

Recycled Materials

 Some materials are not solid wastes when recycled, therefore not hazardous wastes, others are wastes, but subject to less-stringent regulatory control

Excluded Wastes

     Exclusions from the definition of solid waste (21) Exclusions from the definition of hazardous waste (17) Exclusions for waste generated in raw material, product storage, or manufacturing units Exclusions for laboratory samples and waste treatability studies Exclusions for dredged material regulated under the Marine Protection Research and Sanctuaries Act or the Clean Water Act

Characteristic Hazardous Waste

 Not excluded  Exhibits a hazardous characteristic

Characteristics of Hazardous Waste

 Ignitibility: » Can create fire under certain conditions » Spontaneously combustible or flash point less than 60oC » E.g. Waste Oils, Used Solvents

Characteristics of Hazardous Waste

 Corrosivity: » Usually pH less than or equal to 2 or greater than or equal to 12.5

» Very strong acids or bases » E.g. Battery Acids

Characteristics of Hazardous Waste

 Reactivity: – Unstable under normal conditions (white phosphorus).

– May be explosive or release toxic fumes – Reacts violently with water (sulfuric acid).

– Forms potentially explosive mixtures with water or generates gases when mixed with water (sodium).

– Generates toxic gases when exposed to corrosive chemicals (cyanide, sulfide).

– Can explode at standard temp. & pressure – Forbidden explosive found in 49 CFR 173.51, 173.53 or 173.88 (detonators, fireworks, munitions

Characteristics of Hazardous Waste

 Toxicity: » Harmful or fatal when ingested or absorbed » E.g Mercury, Lead, Benzene

Is It Listed Waste?

When determining if a waste is “listed”:  Sources of potentially listed contaminant?

 What process generated the chemical?

    F Waste: Generic process using specific solvents.

K Waste: Specific industry process.

P & U Waste: Unused chemical w/sole active ingredient.



Toluene, MEK, Acetone

Typical Industries Generating Hazardous Waste

            Aerospace Automobile Batteries Electronic component manufacturing Electroplating Inorganic Chemicals Inorganic pigments Iron & Steel Leather tanning & Finishing Metal smelting & Finishing Organic Chemicals Paints & Coating           Perfumes & Cosmetics Pesticides & herbicides Petroleum Refining Pharmaceuticals Photographic Equipment & Supplies Printing Pulp & Paper mills Ship building Textile Mills Wood preservation and processing

Mixture Rule

   The mixture rule is intended to ensure that mixtures of listed wastes with nonhazardous solid wastes are regulated in a manner that minimizes threats to human health and the environment. Even if a small vial of listed waste is mixed with a large quantity of nonhazardous waste, the resulting mixture bears the same waste code and regulatory status as the original listed component of the mixture, unless the generator obtains a delisting. A mixture involving characteristic wastes is hazardous only if the mixture itself exhibits a characteristic

Derived-From Rule

 Any residue from the treatment, storage or disposal of a listed waste is till a hazardous waste  Unless the waste is derived from a characteristic waste and does not exhibita characteristic  Or unless the waste is recycled to make new products

Universal Waste

 Wastes that do meet the regulatory definition of hazardous waste, but are managed under special, tailored regulations. These wastes include: – batteries – pesticides – lamps/fluorescent bulbs – mercury-containing equipment/thermostats
