As our society has changed over time, so have the amount andtypes of wastes we produce. Not only do households discardtrash and garbage, but industrial and manufacturing process-es create many different types of wastes as well. As technolo-gy has advanced, we have continually updated and improved

our methods of waste treatment and management. Today, althoughmany individuals, organizations, and businesses take steps to preventor reduce the amount of waste they generate, it is inevitable thatsome materials still must be discarded. Environmental controls andsound management practices allow us to balance industrial growthwith ecological and human health needs.

In 1965, to encourage environmentally sound methods for dis-posal of household, municipal, commercial, and industrial refuse,Congress passed the first federal law to require safeguards on theseactivities, the Solid Waste Disposal Act. Congress amended this lawin 1976 by passing the Resource Conservation and Recovery Act(RCRA) (pronounced “Ric-ra”). The primary goals of RCRA are to:

n Protect human health and the environment from the potentialhazards of waste disposal.

n Conserve energy and natural resources.

n Reduce the amount of waste generated.

n Ensure that wastes are managed in an environmentally soundmanner.

As more information about the health and environmentalimpacts of waste disposal became available, Congress revised

RCRA in 1980 and in 1984. The 1984 amendments are referred to as theHazardous and Solid Waste Amendments.

RCRA is divided into sections called Subtitles. Subtitles C and D set forth aframework for the U.S. Environmental Protection Agency’s (EPA’s) comprehen-sive waste management program:

n EPA’s Subtitle C program establishes a regulatory framework for managinghazardous waste from generation until ultimate disposal.

n EPA’s Subtitle D program establishes a system for managing solid (primarilynonhazardous) waste, such as household waste.

RCRA also regulates underground storage tanks (USTs) that store petroleumor certain chemical products under Subtitle I. Requirements exist for thedesign and operation of these tanks and the development of systems to preventaccidental spills. Examples of facilities using these tanks include petroleumrefineries, chemical plants, and commercial gas stations.

The Medical Waste Tracking Act of 1988 was a 2-year demonstration pro-gram that expired in June 1991. It created a Subtitle J program designed totrack medical waste from genera-tion to disposal. At present, nofederal EPA tracking regulationsare in effect for medical waste,but many states have adoptedtheir own programs.

The ComprehensiveEnvironmental Response,Compensation, and Liability Act(known as Superfund or CERCLA) is a related statutethat deals with cleaning up inac-tive and abandoned hazardouswaste sites. RCRA, on the otherhand, deals with materials thatare currently destined for dispos-al or recycling.

The term “RCRA” is oftenused interchangeably to refer tothe law, regulations, and EPA

TThhee RRoollee ooff tthhee SSttaatteessIn a given state, the hazardous waste regu-

latory program described in this document maybe run by either EPA or a state hazardouswaste agency. Both of these entities can bereferred to as the “regulatory agency,” depend-ing on the state.

RCRA encourages states to assume prima-ry responsibility for implementing the RCRAprogram, instead of EPA. States that want toadopt and implement the RCRA Subtitle C pro-gram must develop a program for the manage-ment of hazardous waste that is at least asstringent as the EPA program. State programscan be more stringent or broader in scope,however. This process ensures that minimumstandards are met nationwide, while providingflexibility to states in implementing rules.

policy and guidance. The law describes the waste management program man-dated by Congress that gave EPA authority to develop the RCRA program.EPA regulations carry out the Congressional intent by providing explicit, legallyenforceable requirements for waste management. These regulations can befound in Title 40 of the Code of Federal Regulations (CFR), Parts 238 through282. EPA guidance documents and policy directives clarify issues related to theimplementation of the regulations. These three elements are the primary partsof the RCRA program.

This booklet is intended to provide an overall perspective on how RCRAworks, including the roles of EPA, states, tribes, the public, and the regulatedcommunity. It focuses primarily on Subtitle C and presents some informationon Subtitle D as well.

Hazardous wastes come in many shapes and forms. They canbe liquids, solids, contained gases, or sludges. They can bethe byproducts of manufacturing processes or simply dis-carded commercial products, like cleaning fluids or pesti-cides. Whatever their form, proper management and dis-

posal are essential to protect human health and the environment.

RCRA provides a general definition of the term “hazardouswaste.” EPA has defined by regulation which specific materials areconsidered hazardous waste under Subtitle C. Under this defini-tion, the universe of potential hazardous wastes is extremely largeand diverse. The regulatory definition evolves and changes as newinformation becomes avail-able. EPA works closely withindustry and the public todetermine which of thesewastes should be subject tothe RCRA hazardous wasteregulations. The Agencydeveloped four definingcharacteristics of haz-ardous waste and fourlists of specific haz-ardous wastes.

Subtitle C: What Is aHazardous Waste?

According to EPA estimates, of the 13 billiontons of industrial, agricultural, commercial, andhousehold wastes generated annually, more than

279 million tons (2 per-cent) are “hazardous,”

as defined by RCRA regu-lations.

Characteristic WastesA waste is hazardous if it exhibits one or more of the following characteristics:

n Ignitability. Ignitable wastes can create fires under certain conditions or arespontaneously combustible. Examples include waste oils and used solvents.

n Corrosivity. Corrosive wastes are acids or bases that are capable of corrodingmetal, such as storage tanks, containers, drums, and barrels. Battery acid is agood example.

n Reactivity. Reactive wastes are unstable under “normal” conditions. They cancause explosions, toxic fumes, gases, or vapors when mixed with water.Examples include lithium-sulfur batteries and explosives.

n Toxicity. Toxic wastes are harmful or fatal when ingested or absorbed. Whentoxic wastes are disposed of on land, contaminated liquid may drain (leach)from the waste and pollute ground water. Toxicity is defined through a lab-oratory procedure called the Toxicity Characteristic Leaching Procedure(TCLP). The TCLP helps identify wastes likely to leach concentrations ofcontaminants that may be harmful to human health or the environment.Certain chemical wastes and heavy metals are examples of potential toxic wastes.

Listed WastesBy definition, EPA determined that some specific wastes are hazardous.

These wastes are incorporated into lists published by the Agency. These lists areorganized into three categories:

n Source-specific wastes. This list includes certain wastes from specific indus-tries, such as petroleum refining or pesticide manufacturing. Certain sludgesand wastewaters from treatment and production processes in these industries areexamples of source-specific wastes.

n Nonspecific source wastes. This list identifies wastes from common manufac-turing and industrial processes. These include solvents that have been used incleaning or degreasing operations.

n Commercial chemical products. This list includes specific commercial chemi-cal products in an unused form. Some pesticides and some pharmaceuticalproducts become hazardous waste when discarded.

To be considered “hazardous waste,”materials must first meet the legal defini-tion of “solid waste.” Solid waste is dis-carded material, including garbage,refuse, and sludge (solids, semisolids, liquids, or contained gaseous materials).

Solid wastes that meet any of the following criteria are considered hazardous andsubject to EPA regulations. Hazardous wastes are those that:

n Possess one or more of the four characteristics of hazardous waste.

n Are included on an EPA list of hazardous waste.

n Are a mixture of nonhazardous and hazardous waste listed solely for a characteristic(e.g., dirty water mixed with spent solvents).

n Derive from the treatment, storage, or disposal of a hazardous waste (e.g., incinera-tion ash or emission control dust).

n Are soil, ground water, or sediment (environmental media) contaminated with haz-ardous waste.

n Are either manufactured objects, plant or animal matter, or natural geological materi-al (debris) containing hazardous waste that are intended for disposal (e.g., concrete,bricks, industrial equipment, rocks, and grass).

WWhhaatt IIss nnoott aa RReegguullaatteedd HHaazzaarrddoouuss WWaassttee??The following are some of the wastes that have been excluded from RCRA haz-

ardous waste regulations:

n Domestic sewage.

n Irrigation waters or industrial discharges allowed under the Clean Water Act.

n Nuclear material regulated by the Atomic Energy Act.

n Household wastes, even when they include hazardous materials, such as paints andpesticides.

n Certain mining and mineral processing wastes.

All listed wastes are presumed to be hazardous regardless of the concentra-tions of their constituents. They must be handled according to EPA’s SubtitleC hazardous waste regulations. If, however, a company can demonstrate that itsspecific waste is not hazardous, the waste may be “delisted.” Delisted wastes areno longer subject to Subtitle C regulations.

Expanding DefinitionsRCRA regulations were written so that all characteristic and listed hazardous

wastes are regulated under Subtitle C. As newer technologies have becomeavailable and new multimedia (land, air, and water) modeling tools haveemerged, EPA has been able to better evaluate the risks posed by different haz-ardous constituent concentration levels. Consequently, RCRA regulations canbe refined to more closely match the risk of a waste with the appropriate man-agement approaches. The Agency is altering its current approach to managinghazardous wastes so that some wastes will not be subject to full regulation ashazardous wastes. Some may fall out of the realm of Subtitle C requirementsand will be managed as nonhazardous solid waste instead.

EPA designed the RCRA regulations to ensure proper man-agement of hazardous waste from the moment the waste isgenerated until its ultimate disposal—“cradle to grave.” Thisstep-by-step approach monitors and controls hazardouswaste at every point in the waste cycle, thereby protecting

human health and the environment from the dangers of misman-agement. This approach has two key elements:

n Tracking. A tracking system requires each facility handlingwaste to obtain an identification number. Generators must pre-pare a uniform manifest document to accompany any trans-ported hazardous waste from the point of generation to thepoint of final disposal.

n Permitting. EPA or the states must issue a permit to facilitiesbefore they can treat, store, and dispose of hazardous waste.The permit prescribes enforceable management standards forthe wastes.

The regulated community in this system includes those whogenerate, recycle, transport, treat, store, and dispose of hazardouswastes.

The Regulated CommunityGenerators

The hazardous waste management cycle begins with a genera-tor—any person or business that produces hazardous waste or firstcauses hazardous waste to become subject to RCRA regulations.

Examples of generators include owners and operators of large manufacturingfacilities, small businesses, universities, and laboratories.

Under the RCRA regulations, generators are responsible for determiningwhether their waste is hazardous and accounting for the final disposal of theirwaste. Generators are regulated according to the amount of waste they produceand are categorized into three groups:

n Large Quantity Generators (LQGs) are those that generate the largest amountof hazardous waste—more than 2,200 pounds (1,000 kilograms) per calen-dar month, which is about five full 55-gallon drums. Since this categoryincludes about 20,000 companies that produce the majority of the nation’swaste, these generators are regulated more stringently than their counter-parts who generate less waste. Examples of LQGs include pharmaceutical com-panies and chemical manufacturers.

n Small Quantity Generators (SQGs) are those that generate between 220pounds (100 kilograms) and 2,200 pounds (1,000 kilograms) of hazardouswaste per calendar month. Examples of SQGs include laboratories, printers,and dry cleaners.

n Conditionally Exempt Small Quantity Generators (CESQGs) are those thatgenerate less than 220 pounds (100 kilograms) of hazardous waste per cal-endar month. Because these generators produce a small amount of haz-ardous waste and because full regulation would present an economic burdenon businesses, CESQGs are subject to very minimal requirements. Examplesof CESQGs include 1-hour photo labs and dental offices.

RCRA regulations apply to facilities that manage waste on site, as well as tothose that ship waste off site. About 98 percent of the nation’s hazardous wasteis treated or disposed of by generators on site. These generators are typicallylarge businesses that can afford treatment equipment and possess the necessaryspace for storage and disposal. Smaller firms, and those in crowded urban loca-tions, are likely to transport their waste off site where it is managed by a com-mercial firm or a publicly owned and operated facility.

Generators that send their waste off site are required to package, mark, andlabel their waste properly for transportation. Proper packaging ensures that nohazardous waste will escape from containers during transport. Marking andlabeling enables transporters and public officials, including those who respondto emergencies, to rapidly identify the waste and its hazards.

Hazardous Waste MinimizationProper hazardous waste management requires a waste minimization plan. To

reduce the amount or toxicity of hazardous waste that must be managed (andtherefore the amount of waste subject to regulation), many generators reduce,reuse, or recycle as part of their everyday practices. The most environmentallysound and economically efficient way of managing any waste is not to generateit in the first place (source reduction). Facilities can avoid creating hazardouswastes, or limit the amount created, by not mixing hazardous and nonhaz-ardous wastes, by changing some materials or processes, and by safely storinghazardous products and containers to avoid spills and leaks.

If hazardous wastes are generated, they often can be recycled in an environ-mentally sound manner. In the context of hazardous waste management, thereare certain practices or activities that are defined as recycling. A recycled mater-ial is one that is used, reused, or reclaimed. For example, cleaning solvents thatbecome dirty through use can be filtered (reclaimed) and used again instead ofbeing disposed of. The term “waste minimization” includes source reductionand environmentally sound recycling.

Wastes that cannot be recycled must be treated to reduce the toxicity of thehazardous constituents and the ability of the constituents to move throughoutthe environment. Treatment residues must be disposed of in an environmen-tally sound manner.

TransportersTransporters pick up properly packaged and labeled hazardous waste from

generators and transport it to designated facilities that recycle, treat, store, ordispose of the waste. They must put proper symbols on the transport vehicle toidentify the type of waste being transported. The U.S. Department ofTransportation (DOT) jointly regulates the transportation of hazardous waste.DOT specifies the markings, labels, and packaging required to ship hazardouswaste. These symbols, like the labels on the hazardous waste containers, enablefirefighters, police, and other officials to identify the potential hazards immedi-ately in case of an emergency. Because an accident involving hazardous wastecould create very serious problems, EPA regulations also require transporters tocomply with procedures for hazardous waste spill cleanup.

Treatment, Storage, and Disposal FacilitiesTreatment, storage, and disposal facilities (TSDFs) receive hazardous waste

from generators or other TSDFs. Treatment facilities use various processes to

alter the character or composition of a hazardous waste. Some treatmentprocesses enable waste to be recovered and reused in manufacturing settings,while other treatment processes reduce the volume or hazard of waste to facili-tate further storage or disposal. Storage facilities hold hazardous waste temporar-ily until it is treated or disposed of. Treatment and storage activities take placein various units such as tanks, containers, incinerators, surface impoundments,containment buildings, and waste piles. Disposal facilities usually place haz-ardous waste in landfills or surface impoundments after it has been treatedproperly (see page 14 for more information).

One common method of treatment (and disposal) of hazardous waste isincineration, or combustion. In the United States, almost 300 facilities burnalmost 4 million tons of hazardous waste in incinerators each year. Another 1million is disposed of in other types of combustion facilities, known as boilersand industrial furnaces. These units offer an effective technology for managingmuch hazardous waste. The RCRA program specifically subjects these units tostrict emissions controls and other requirements. In addition, all new unitsmust receive a permit from the state or federal permitting agency to operate

13

AApppprrooaacchheess ttoo WWaassttee MMiinniimmiizzaattiioonnn Substitution of raw materials might offer the greatest opportunity for waste mini-

mization. By replacing a raw material that generates a large amount of hazardouswaste during its processing with one that generates little or none, manufacturers cansubstantially reduce their waste volume.

n Manufacturing process changes consist of either eliminating a process that producesa hazardous waste or altering a process so that it no longer produces the waste.

n Substitution of products can also be effective. For example, citrus-based solventsoften can be used instead of chlorinated solvents for cleaning or coating.

n Recycling (also referred to as recovery and reuse) is the process of removingreusable elements from a waste and returning them to productive use. Generatorscommonly recycle solvents, acids, and metals.

n Source separation (or segregation) keeps hazardous waste from contaminating nonhaz-ardous waste through management practices that prevent the wastes from coming intocontact with each other. This is the cheapest and easiest method of reducing the vol-ume of hazardous waste to be disposed of and is widely used by industry. In addition toreducing disposal costs, source separation reduces handling and transportation costs.

and must pass a test known as a trial burn, before operation begins to ensurethat these units will not endanger human health or the environment (see page19 on permitting). EPA continually evaluates the safety of hazardous wastecombustion by examining and revising emissions standards.

Land Disposal RestrictionsAbout 23 million tons of hazardous waste are land disposed annually. This

widespread disposal of hazardous waste in units located directly on the landhas the potential to contaminate soil and ground water. To adequately protect

TTyyppeess ooff LLaanndd DDiissppoossaalln Landfills are disposal facilities where hazardous waste is placed in or on land. Properly

designed and operated landfills are double-lined to prevent leakage. They also areequipped with systems that collect surface water runoff (like rain) that can come in con-tact with waste and become contaminated.

n Surface impoundments are double-lined natural or fabricated depressions or dikedareas that can be used to treat, store, or dispose of hazardous waste. Surfaceimpoundments may be any shape and any size (from a few hundred square feet tohundreds of acres in area). Surface impoundments are often referred to as pits, ponds,lagoons, and basins.

n Underground injection wells are steel- and concrete-encased shafts into which haz-ardous wastes are deposited by force and under pressure. Liquid hazardous wastesare commonly disposed of in underground injection wells. Injecting wastes intoencased wells deep in underground land formations protects ground-water aquifersfrom risk of contamination.

n Waste piles are noncontainerized, lined accumulations of solid, nonflowing hazardouswaste. While some are used for final disposal, many waste piles are used for tempo-rary storage until the waste is transferred to its final disposal site.

n Land treatment is a disposal process in which hazardous waste is applied onto orincorporated into the soil surface. Natural microbes in the soil break down or immobi-lize the hazardous constituents. Land treatment facilities are also called land applica-tion or land farming facilities.

CCoommmmoonn HHaazzaarrddoouuss WWaassttee TTrreeaattmmeenntt TTeecchhnnoollooggiieessSeveral processes exist for making hazardous wastes less hazardous:

n Biological treatment uses micro-organisms to break down hazardous organic com-pounds in a waste stream and make the waste less toxic.

n Carbon adsorption is a chemical process that removes hazardous substances from thewaste using specially treated carbon. This method is particularly effective in removingorganic compounds from liquid waste.

n Dechlorination removes chlorine from a substance to make it less toxic.

n Glycolate dehalogenation uses chemical substances to react with hazardous contami-nants to change their structure and toxicity.

n Incineration (or combustion) destroys waste or makes it less hazardous through burn-ing. Incineration is frequently used to destroy organic wastes.

n Thermal treatment uses elevated temperatures as the primary means of changing thechemical, physical, or biological character of a waste. (Examples include wet air oxi-dation, molten salt pyrolysis, and calcination.)

n Neutralization makes certain substances less acidic and other substances less alkaline.

n Oxidation makes a waste less toxic by combining it with oxygen.

n Precipitation removes solids from a liquid waste so that thehazardous solid portion can be disposed of safely.

n Soil washing uses water or a washing solution in mechanicalprocesses to scrub soils and remove hazardous contami-nants.

n Solidification and stabilization removes wastewater from awaste or changes it chemically, making it less likely to betransported by water.

n Solvent extraction separates haz-ardous constituents from oily wastes,oils, sludges, and sediments toreduce the volume of waste thatmust be disposed of.

treated so that the concentration of hazardous constituents is below a certainlevel established for each waste. There are numerous treatment technologiesavailable and new ones continually being developed (see box on page 16).

Used Oil Management StandardsEPA has established a set of required practices, or management standards,

for recycling used oil and burning it for energy recovery. These are common-sense, good-business practices designed to maximize recycling and minimizedisposal of used oil, as well as to ensure its safe handling. Used oil comes fromautomotive crankcases, machine lubricants, and industrial processes. Duringnormal use, impurities, such as dirt, metal scrapings, water, or chemicals, canget mixed in with the oil so that in time the oil no longer performs well.Eventually, this oil must be replaced with virgin or re-refined oil to do the jobat hand. Then, used oil must be either disposed of, recycled, or burned forenergy recovery.

Used oil can be treated to remove hazardous contaminants and reused as anew lubricating oil or as a fuel. An estimated 380 million gallons of used oilare recycled each year. It takes 42 gallons of crude oil, but only 1 gallon of usedoil, to produce 2-1/2 quarts of new, high-quality lubricating oil.

The used oil management system is designed to minimize the potential risksassociated with used oil. These standards impose requirements on used oil gen-erators, collection centers, transporters, and processors. The used oil programalso imposes standards on used oil burners and marketers to ensure that theburning of used oil for energy recovery is conducted in a manner that is pro-tective of the environment. For example, used oil destined for burning must betested for hazardous contaminants and burned in units that can control haz-ardous air emissions. Used oil generators also can burn used oil in space heatersused at their place of business.

The RCRA StructureThe Tracking System

To assist in tracking shipments of waste, EPA requires LQGs, SQGs, trans-porters, and TSDFs to obtain EPA identification numbers. LQGs and SQGsmust also prepare Uniform Hazardous Waste Manifests for each shipment of haz-ardous waste. A manifest is a form containing copies for all participants involvedin the waste shipment. It identifies the type and quantity of waste and the gener-

ator, transporter, and facility to which the wasteis being shipped. Generators must also certify onthe manifest that they are minimizing theamount and toxicity of their waste and that themethod of treatment, storage, or disposal theyhave chosen will minimize the risk to humanhealth and the environment. When the wastereaches its final destination, the owner of thatfacility returns a copy of the manifest to the gen-erator to confirm that the waste has arrived.

If the waste does not arrive as scheduled,generators must immediately notify EPA or the authorized state agency so thatit can investigate and take appropriate action. Generators, transporters, andTSDFs must retain copies of the manifest for 3 years. Every other year, genera-tors also must provide information on their activities to their authorized stateagency or EPA.

The Permitting SystemOwners or operators of TSDFs must obtain a permit in order to operate. A

permit specifically allows a facility to treat, store, or dispose of hazardous wasteand outlines the precautions that must be taken to manage the waste in a man-ner that adequately protects human health and the environment.

New TSDFs must receive a permit before they begin construction. OperatingTSDFs with expiring permits must submit new permit applications 6 monthsbefore their existing permits run out. TSDFs operating under interim status mustalso apply for a permit. Congress granted interim status to facilities that alreadyexisted when RCRA was enacted or that were already operating when new wasteswere listed. Interim status allows facilities to continue operating while their permitapplications are being reviewed by the federal or state permitting agency. Whileboth permitted and interim status TSDFs are subject to similar standards, theinterim status standards are designed to be self-implementing. Generally, permit-ted and interim status TSDFs must:

n Analyze and identify wastes prior to treatment, storage, and disposal.

n Prevent the entry of unauthorized personnel into the facility by installingfences and surveillance systems, and by posting warning signs.

n Inspect the facility on a periodic basis to determine if there are any problems.

n Train employees in safe use of equipment and emergency response procedures.

A hazardous waste mani-fest must accompany everywaste shipment. The result-ing documentation tracks thewaste’s progress to TSDFs. Amissing form alerts the gen-erator to investigate, whichmay mean calling the stateagency or EPA.

n Prepare a contingency plan for emergencies and establish other emergencyresponse procedures.

n Comply with the manifest system and with various reporting and record-keeping requirements.

n Comply with facility-specific standards as dictated in the permit.

In addition to these general requirements, all TSDFs must comply withspecific design and operating standards for their hazardous waste treatment,storage, and disposal units. These standards are especially important for dis-posal units, which must ensure that disposed waste will not leach or otherwiseescape into soil or ground water. Disposal unit standards:

n Ban liquids from landfills.

n Ban underground injection of hazardous waste within 1/4-mile of a drink-ing water well.

n Require stringent structural and design conditions, such as double liners,leachate collection systems, and ground-water monitoring.

n Limit facility sitings in unstable hydrogeologic areas.

EPA also established regulations to address air emissions from hazardous wastedisposal since some hazardous waste compounds can evaporate into the air. Toprevent such escapes into the atmosphere, EPA requires certain equipment to beused for recycling, treatment, storage, and disposal of some hazardous wastes.

Closure and Financial AssuranceRCRA regulations and permits set forth certain procedures that are designed

to protect the environment and surrounding communities when owners andoperators of hazardous waste facilities close their sites. In addition, RCRA setsstandards for ground-water monitoring, disposal unit maintenance, and securitymeasures that some owners and operators of hazardous waste facilities will needto follow for up to 30 years after the facility closes (known as postclosure care).

Closure activities can be expensive, and some facilities might not be able tocover these costs at the time of closure. For example, if a company undergoesbankruptcy and has little money left at the time of the closure of its TSDF, itmight not be able to provide the required closure and postclosure care. To addressthis situation, RCRA regulations require owners and operators to:

n Establish separate, secure financial assurance mechanisms (such as trustfunds, surety bonds, and letters of credit) to pay for completion of all clo-sure and postclosure operations.

n Be prepared to pay for 30 years of ground-water monitoring, disposal unitmaintenance, and security measures after the facility closes.

n Demonstrate financial assurance for third-party liability to cover any acci-dents or mismanagement that results in the release of hazardous waste. Suchfunds can be used to compensate citizens or other third parties for any dam-age to neighboring property or injury to human health.

SSttaattee AAuutthhoorriizzaattiioonnThe hazardous waste regulatory program described in this document may be run by

EPA or a state hazardous waste agency. Currently 47 states and two territories havebeen granted authority to run Subtitle C RCRA programs. As EPA continues to promul-gate new or revised rules, states must become authorized to implement those rules.Thus, state authorization is an ongoing process.

EPA’s regional offices implement and enforce RCRA in states and territories that donot have authorized programs. In states that are authorized, EPA can step in to assiststates in enforcing the law, if needed. Otherwise, states that are authorized to operateRCRA programs oversee the hazardous waste tracking system in their state, operate thepermitting system for hazardous waste facilities, ensure public participation require-ments are met, act as the enforcement arm in cases where individuals or companiespractice illegal hazardous waste management, and implement all other aspects of theRCRA program.

In terms of permitting hazardous waste facilities, authorized states are generally con-sidered to be the “permitting agency.”

The public plays an important role in the permitting process for both haz-ardous and municipal solid waste facilities. Facilities applying for a permit mustinvolve the public in some aspects of the process. Businesses and the state orfederal permitting agency also must make information available to the public.The public has opportunities to submit comments and request public hearings.The following are some of the ways in which the public can stay involved:

n When a business submits a permit application, it must hold an informal meet-ing with the public and advertise the meeting with signs and/or advertisementsin the paper or radio. The business must explain the plans for the facility,including information about the proposed processes it will use and wastes itwill handle. Members of the public can sign up on the facility’s mailing list.

n When the permitting agency receives a permit application from the busi-ness, it sends a notice to everyone on the mailing list. The application isthen available for public review.

n The permitting agency may require the business to set up a library for thepublic with available relevant documents, such as the permit applicationand reports.

n The permitting agency announces its decision about granting or denyingthe permit by sending a letter to everyone on the mailing list and placing anotice in a newspaper or broadcasting over the radio. It also issues a factsheet to explain the decision. Once the notice is issued, the public has 45days to comment on the decision. Citizens may request a public hearing bycontacting the permitting agency.

n The permitting agency must consider and respond to all public commentswhen making its decision.

n The public has the right to appeal the final permit decision.

Cleaning up hazardous waste facili-ties, known as corrective action, is alsoof concern to citizens and local com-munities. Since spills from TSDFs canaffect entire municipalities, RCRAguarantees that the public will have arole in the facility cleanup process. Forexample, the corrective action processgives the public access to facilityinspection information, requires publicnotice of remediation proceedings, andallows the opportunity for public com-ment and participation in the remedyselection process.

Public participation initiatives arealso used to remedy the disproportion-ate effects of environmental pollutionon particular groups, such as minorityand low-income populations. Forexample, through efforts to ensure environmental justice, EPA is analyzing howto incorporate public participation into decisions concerning the siting of haz-ardous waste facilities and the prioritization of corrective action cleanups.

Many avenues exist for citizens tolearn about and participate in what ishappening around them, in addition tothose offered under the RCRA pro-gram. A related law, known as theEmergency Planning and CommunityRight-to-Know Act, establishes a citi-zen’s right to obtain information abouttoxic and hazardous chemicals handledat facilities in the community. Onesuch avenue is the Toxics ReleaseInventory (TRI). Through this program,facilities across the country arerequired to report the quantities of 643different toxic chemicals that arereleased into the environment eachyear. Facilities must report whetherthese toxic chemicals were releasedinto the air or water or disposed of inunderground injection wells or landfills.Facilities also have to indicate whichreleases were sent to a commercialSubtitle C landfill.
