A NORTH AMERICAN APPROACH TO ENVIRONMENTAL CONCERNS

Three nations working together to protect the environment

The Commission for Environmental Cooperation (CEC) was established byCanada, Mexico and the United States in 1994 to address transboundary environ-mental concerns in North America. While the idea to create such a commissionoriginated during the negotiations of the North American Free Trade Agreement(NAFTA), it derives its formal mandate from the North American Agreement onEnvironmental Cooperation (NAAEC).

The NAAEC builds upon and complements the environmental provisions estab-lished in NAFTA. It creates a North American framework whereby goals related totrade and the environment can be pursued in an open and cooperative way.

In broad terms, the NAAEC sets out to protect, conserve and improve the envi-ronment for present and future generations. How? The parties to the Agreement setout the following objectives:

• to protect the environment through increased cooperation;

• to promote sustainable development based on mutually supportive environmen-tal and economic policies;

• to support the environmental goals of NAFTA and avoid creating trade distor-tions or new trade barriers;

• to strengthen cooperation on the development of environmental laws andenhance their enforcement; and

• to promote transparency and public participation.

In signing the NAAEC, the governments of Canada, Mexico and the UnitedStates committed themselves to a core set of actions, including:

• reporting on the state of the environment;

• striving for improvement of environmental laws and regulations;

• effective enforcement of environmental law; and

• publication and promotion of information.

This is the first of a series of documents comprising a North American Report onPollutant Releases and Transfers prepared by the Secretariat of the Commission forEnvironmental Cooperation (CEC). This first document provides an overview ofthe status and compatibility of the Pollutant Release and Transfer Register programsin Canada, the United States and Mexico. The second document, expected to bepublished at the end of 1996, will analyze the 1994 data reported to Canada andthe US, and profile the pilot project in Mexico. The CEC Secretariat intends topublish an annual report which will analyze the publicly available data reported tothe North American governments.

In the development of this report, the CEC Secretariat invited over 30 interestedpersons throughout North America to comment on the draft work products. TheCEC Secretariat wishes to thank everyone who assisted in this report and who pro-vided extensive reviews of the materials, especially:

33/50 Program: A voluntary program of the EPA encouraging reductions of TRIreleases and transfers of 17 chemicals by 33 percent from 1988 to 1992 and by 50percent from 1988 to 1995 through pollution prevention and other means.

Chemical category: A group of closely-related individual chemicals that are count-ed together for purposes of PRTR reporting thresholds, as well as release and trans-fer calculations. The chemicals are reported to the PRTR under a single name.

Energy recovery: The combustion or burning of a chemical to produce heat.

Environmental management hierarchy: The types of waste management plussource reduction that are prioritized as to environmental desirability. In order ofpreference, the one most beneficial to the environment is source reduction (pollu-tion prevention at the source), followed by recycling, energy recovery and treat-ment; disposal is the least desirable option.

Environmental media: The air, bodies of water such as oceans, rivers, lakes andstreams; land areas; and areas underground.

Incineration: A method of treating solid, liquid or gaseous wastes by burning.

Materials accounting: Data that describe the flow of a chemical through an indus-trial facility. Includes the amount of the chemical brought on-site, put into invento-ry or removed from it, the amount produced and/or consumed (transformed) duringthe production process, the amount shipped as or in a product, and the amountgenerated as waste.

Materials balance: Calculations relating to an entire industrial process that “bal-ance” inputs and outputs.

Inputs OutputsBrought on-site Consumed in productFrom inventory To inventoryProduced on-site Shipped in productRecycled Waste (includes recycled)

Non-production-related waste: Waste that is generated as a one-time event,including large accidental spills, waste from a remedial action to clean up environ-mental contamination from past disposal practices, or other wastes not occurring asa routine part of production operations. This does not include spills occurring as aroutine part of production operations that could be reduced or eliminated byimproved handling, loading or unloading procedures.

Off-site transfers: Chemicals in waste that are moved off the grounds of the facili-ty. Includes transfers of waste sent to other facilities or other locations, such as haz-ardous waste treatment facilities, municipal sewage treatment plants or landfills.

On-site: Within the boundaries of the facility, including areas where wastes may bestored, treated or disposed of that are separate from the production processes butstill within the boundaries of the reporting facility.

Point source: The origin of known or deliberate environmental releases from fixedpoints such as smokestacks and wastewater discharge pipes.

Polynuclear aromatic hydrocarbons (PAHs): A family of organic chemicals basedon the chemical structure of benzene. This family includes a number of petroleumproducts and products of combustion processes.

Production ratio/activity index: The ratio of the production level associated withthe chemical in the current reporting year to the previous year’s level.

Production-related waste: Chemical waste that is generated as a result of routineproduction and could potentially be reduced or eliminated by improved handling,more efficient processes, change in product or product quality, or change in rawmaterials. This does not include spills resulting from large-scale accidents or wastefrom remedial actions to clean up contamination.

Recycling: Extraction of a chemical from a manufacturing process stream thatwould otherwise have been treated as waste, with the extracted chemical beingreused in the original production process, in another production process, or sold as aseparate product.

Releases: Quantities of a chemical in waste released on-site to air, water, land orunderground injection.

Source reduction: A strategy for reducing pollution that involves preventing thegeneration of waste in the first place, rather than cleaning it up, treating it, or recy-cling it after it has been produced.

Source reduction activity: The types of activities undertaken to accomplish sourcereduction. The term includes equipment or technological modifications, process orprocedure modifications, reformulations or redesign of products, substitution of rawmaterials, as well as improvements in housekeeping, maintenance, training orinventory control.

Tonnes: A metric tonne, which is 1000 kg, 1.1023 short tons, or 0.9842 long tons.

Transfers: Chemicals in waste that are sent from the reporting facility to a facilitythat treats or disposes of the chemical. Transfers include chemicals sent off-site forrecycling and energy recovery, under the TRI definition of wastes and transfers.

Treatment: A variety of processes that change the chemical in waste into anothersubstance.

Use: The amount of chemical that is used as an input to or manufacturing aid dur-ing the production process or is produced at a facility. (For RETC, the definition of“use” does not include chemicals produced.)

Waste: The amount of chemical not converted into product, and not consumed ortransformed during the production process. PRTRs differ as to whether materialsdestined for recycling or recovery are included or not in their definition of waste.

Worldwide, people increasingly are seek-ing information about environmentalconditions in their communities.Corporations are responding by publish-ing environmental reports on their oper-ations. Governments are creating pub-licly accessible, national data bankscalled Pollutant Release and TransferRegisters (PRTRs), that list pollutantsreleased into the air, land and water;injected underground; or transferred off-site. PRTRs are a new and innovativeenvironmental tool that can be used foran ever-growing number of purposes.

The oldest PRTR in North America,the US Toxic Release Inventory (TRI),reflects the idea that citizens can play animportant role in helping communitiesachieve tangible results to protecthuman health and the environment. In1993, more than 23,000 industriesreported releasing more than 1,000,000kilograms of pollutants to the TRI, andmore than 2,000,000 kilograms weretransferred to off-site locations. Also in1993, the first year of reporting to thenew Canadian National PollutantsRelease Inventory, close to 1,500 indus-tries reported releasing approximately225,000 kilograms of pollutants to theenvironment, while almost 150,000kilograms were transferred off-site.

To help fulfill its commitments to theOrganization for Economic Cooperationand Development (OECD) and Agenda21, Mexico is developing its PollutantRelease and Transfer Register, to beknown as Registro de Emisiones yTransferencia de Contaminantes (RETC).This spring, approximately 80 industriesin the state of Querétaro reported theirreleases and transfers in a case studydesigned to test the proposed nationalregister.

The uses of the TRI and NPRI databas-es continue to grow, often in ways thatwere not contemplated at the start ofthe inventories. Companies have usedpollutant release and transfer data toreview their operations, set voluntaryreduction targets and report to the pub-lic. Now, banks, insurance companiesand real estate brokers use the releaseand transfer data as a method to assess acompany’s operations. Based on PRTRdata, governments can encourage pollu-tant reductions, set technical assistancepriorities, and measure progress. As ameasure of public interest in the data-bases, an estimated 21,000 searches ofthe TRI data were made in 1995 usingthe Right-to-Know Computer Network(RTK NET).

The Commission for EnvironmentalCooperation (CEC) is interested inhelping citizens fit together information

Executive Summary

xiiiPutting the Pieces Together

Tracking of environmental pollutantsthrough PRTRs is essential to:

• enhance environmental quality;• increase public and industry under-

standing of the types and quantitiesof toxic chemicals or pollutantsreleased into the environment andtransferred off-site as waste;

• encourage industry to prevent pollu-tion, reduce the generation, releaseand transfer of waste, and assumeresponsibility for chemical use;

• track environmental progress; and• assist in identifying government

priorities.

The TRI, NPRI and proposed RETC sharemany characteristics. They are intendedfor regular and active public dissemina-tion, and they all report:

• on individual chemicals;• on individual facilities;• on releases and transfers;• on an annual basis; as well as• using computerized data manage-

ment; and• allowing for limited trade secrecy.

from the North American PRTRs so asto give a picture of pollutant releasesand transfers across North America.

This report describes the three NorthAmerican PRTRs along with their simi-larities and differences, so that appropri-ate and effective data comparisons canbe made. The second report in thisseries, expected in February 1997, willanalyze publicly available 1994 datafrom American and Canadian registersand summarize the experience from theMexican pilot project. This ground-

breaking analysis will assist in leadingthe way for other countries to share andcompare their data.

xiv Putting the Pieces Together

The TRI, NPRI and proposed RETC alsohave differences that can make datacomparisons difficult. They differ in the:

• chemicals to be reported;• thresholds for reporting;• type of facilities required to report;• industrial classification system; and• classification of small releases and

transfers.

A small plume of air rises from theneighborhood factory. What pollutantsare in this plume? For eight years, Americancitizens have been able to get answers tothese questions from the Toxic ReleaseInventory (TRI), a computerized databaselisting pollutants that are released andtransferred into the air, land and wateror else injected underground. For thepast year, Canadians have asked similarquestions of the National PollutantRelease Inventory (NPRI). Mexico iscurrently designing its new system, theRegistro de Emisiones y Transferencia deContaminantes (RETC), which plans tocollect data on pollutant releases andtransfers in 1997.

The Commission for EnvironmentalCooperation (CEC) recognizes theimportance of pollutant release andtransfer registers, such as the TRI, NPRIand proposed RETC as a method ofenhancing the quality of the NorthAmerican environment. The CEC wasset up under the North American Agree-ment on Environmental Cooperation(NAAEC). It facilitates cooperation andpublic participation to foster conservation,protection and enhancement of theNorth American environment for thebenefit of present and future generations,in the context of increasing economic,trade, and social links between Canada,the US and Mexico.

At the Second Annual Regular Sessionof the CEC, the Environment Ministersof the three North American countriesresolved to establish a North AmericanPollutants Release Inventory as noted inthe communiqué:

“This past year, the NAFTA partnersbegan to examine their common needfor an inventory of pollutant emissions.We have decided to create a NorthAmerican Pollutant Release Inventory

that will bring together, for the firsttime, existing national public informationabout emissions and long-rangetransportation of pollutants. This vitaltool for improving the quality of theenvironment will be the result ofharmonized methods of reporting onpollutant emissions of mutual concern.”

1.1 WHAT ARE POLLUTANTRELEASE AND TRANSFERREGISTERS (PRTRS)?

PRTRs, such as TRI, NPRI and theproposed RETC, provide detailed dataon types, locations and amounts ofpollutants released on-site and transferredoff-site by industrial facilities. The federalgovernments then provide annual reports,which are released to the public alongwith the database. Many corporationsalso use the data to publicly report ontheir environmental performance. PRTRsare an innovative tool that can be usedfor a variety of purposes.

Many companies have responded toPRTR results by conducting an internalenvironmental review and setting goalsfor waste reductions. For example, afterreviewing some of its first TRI results,Monsanto both committed to and achieveda 90 percent reduction in air emissions.

Chapter 1.0: Introduction

1Introduction

Tracking of environmental pollutantsthrough PRTRs is essential to:

• enhance environmental quality;• increase public and industry under-

standing of the types and quantities ofpollutants released into the environ-ment and transferred off-site as waste;

• encourage industry to prevent pollution;to reduce waste generation, releasesand transfers; as well as to assumeresponsibility for chemical use;

• track environmental progress; and• assist in the identification of govern-

ment priorities.

Page 14: PUTTING THE PIECES TOGETHER...Putting the Pieces Together iii Retail Price: $20.00 US Diskettes: $15.00 US For more information, contact: Secretariat of the Commission for Environmental

PRTR data are also a useful method totrack environmental progress. Experiencewith American TRI data has shown a 43percent reduction in pollutant releasesreported from 1988 to 1993.

Government priorities can shift basedon situations revealed in the PRTR data.New programs or enforcement measurescan be tailored to accomplish specificgoals, such as reducing the pollutantsreleased in greatest quantities or targettingchemical releases in a particular region.For example, in 1991, the EPA launchedthe 33/50 Program, seeking voluntaryreductions in the releases and transfersof 17 chemicals on the TRI list. Theresult is that industry surpassed the nationalgoal of a 33 percent reduction by 1992(based on 1988 levels) and is expectedto exceed the 50 percent reduction by1995. TRI data are also being used to setenforcement priorities and to targetindustries for technical assistance.

1.2 WHY IS A NORTHAMERICAN REPORT ONPRTRS NEEDED?

North Americans are increasingly askingquestions such as:

• What pollutants are being released in the greatest quantities in NorthAmerica?

• Which companies and industries aremaking the most progress in reducingtheir wastes?

• Are most pollutants released to the air,land or water in North America?

• How do pollutant releases compareamong the US, Canada and Mexico?

• Are more pollutants recycled in theUS, Canada or Mexico?

• What pollutants, in what quantities,are being released near the borders ortransferred across the borders of eachcountry?

• What pollutants could be subject tolong-range transportation to areassuch as the Arctic?

• How do estimates from differentpollutant databases compare?

The CEC wishes to assist citizens inintegrating the existing information inCanada, US and Mexico to answer theseand other questions. Some answers canbe found in toxic release and transferreports from Canada and the UnitedStates. But these systems also haveimportant differences such that super-ficial comparisons are not useful.

How can apples-to-apples comparisonsbe made? The citizen, policy maker,scientist or worker seeking answerswould currently have to review reportsfrom each of the three countries, studythe different pollutant lists, and comparethe differences between the two establishedsystems and the third developing systemto determine what adjustments wererequired to make the comparisons valid.

1.3 REPORT FOCUS

This report describes each of the NorthAmerican PRTRs and describes theirsimilarities and differences so that validdata comparisons can be made. The reportalso puts the PRTRs into an internationalcontext and describes potential uses ofthe data. With the aid of this report and

2 Putting the Pieces Together

The goals of the North American ReportSeries on Pollutant Releases andTransfers are:

• to increase public access and under-standing of pollutant releases andtransfers in North America; and

• to stimulate compatibility across NorthAmerica for basic information fromPRTRs.

the second, forthcoming one summariz-ing the Mexican pilot project data, aNorth American analysis of pollutantreleases and transfers will be possible for

the first time. Hopefully, this series ofreports will also increase communicationand cooperation between the threegovernments on PRTRs.

systems. The Council also instructed itsEnvironment Policy Committee toconsider how the OECD can assist non-member countries establish PRTRs.

While the development of the US ToxicRelease Inventory (TRI) and the CanadianNational Pollutant Release Inventory(NPRI) preceded the Rio Declaration,the proposed Mexican Registro de Emisionesy Transferencia de Contaminantes (RETC)is one of many national initiatives takensince the adoption of the Rio Declaration.It may become the first PRTR to followthe Declaration and, as such, it mayserve as an example for other rapidlyindustrializing countries.

Other international agreements contributeto the fundamental need for the PRTRconcept. The proposal that countriesshould both collect and make publicinformation on chemical emissions hasbeen gaining steady acceptance. Article4 of the 1992 United Nations FrameworkConvention on Climate Change2 includesa commitment from the parties to establish,update, publish and provide nationalinventories of human-generated emissionsof greenhouse gases to the Conference ofParties in accordance with nationallegislation. Article 6 further states thatthe parties shall facilitate public accessto information concerning climate change.

The Montreal Protocol on Substancesthat Deplete the Ozone Layer3 was adoptedin 1987 and amended in 1990, 1991 and1992. It commits the Parties to providestatistical data on the production, importa-tion and exportation of ozone-depletingsubstances. Reference may also be madeto the 1989 Basel Convention on theControl of Transboundary Movements ofHazardous Wastes and their Disposal.4

This requires the Parties to obtain informa-tion on transboundary movements of

wastes and to cooperate in the dissemina-tion of the information. The 1979 GenevaConvention on Long-Range TransboundaryAir Pollution5 was signed by Canada andthe United States. It contains similarprovisions under which the Parties agreeto share information on air pollutionemissions, but remains silent on publicaccess to this data.

In 1983, the US and Mexico bilaterallysigned the La Paz Agreement.6 ItsAnnex IV provides for the monitoring of sulphur dioxide emissions from coppersmelters and the exchange of monitoringdata between the Parties. Article 16 ofthe La Paz Agreement stipulates thatinformation gathered under the Agreementmay be made available to third parties bymutual consent of the signatory nations.

The 1991 Agreement Between Canadaand the US on Air Quality7 provides forthe exchange of information on airemissions between the Parties and thepreparation of biannual data reports.Article VIII stipulates that these reportsshall be made public. In the areas ofwater pollution control, the US andCanada signed the 1978 Great LakesWater Quality Agreement,8 whichprovides for the development of waterpollution control plans, publication ofperiodic reports, and public release ofthese reports. These bilateral agreementscontain provisions which are compatiblewith the development of PRTRs. However,the PRTR concept is unique. It is anintegrated, multimedia report designedto provide public information and toachieve accountability and pollutionreduction objectives.

The development of a North Americanreport combining PRTR data fromCanada, the US and Mexico is a measuredesigned to implement subparagraph (a),

North American Pollutant Release andTransfer Registers (PRTRs) are on theforefront of a worldwide trend towardincreased collection and public disclosureof industrial data on pollutants.

2.1 INTERNATIONALAGREEMENTS

The PRTR concept is unique in that itbrings together two principles that havebeen recognized by international environ-mental accords:

• citizens should have access toenvironmental information; and

• industries should provide informationon emissions of toxic substances intothe environment.

These two underlying principles, embodiedseparately in recent agreements, jointlyrepresent the fundamental need for PRTRs.

As such, there are no internationalagreements that provide specifically forthe preparation of national, bilateral ormultilateral PRTRs. The three NorthAmerican Free Trade countries are notparty to an international agreementspecifically mandating the developmentof PRTRs. However, the countries aresignatories of several internationalconventions and bilateral agreementsthat provide some basis for certaincomponents of PRTRs.

The three North American Free Tradecountries are parties to several interna-tional instruments and bilateral agreementsthat either advocate the preparation ofPRTRs or implement certain componentsof PRTRs.

Certainly, the most prominent multilateralstatement supporting the developmentof PRTRs is the Rio Declaration on theEnvironment and Development,1

adopted by the United Nations Conferenceon the Environment and Developmentheld in Rio de Janeiro in June 1992.This Declaration was adopted togetherwith Agenda 21, an action plan designedto implement the Declaration itself.Canada, the US and Mexico supportedthe resolution adopting both the RioDeclaration and Agenda 21. Theseinstruments have established the mostrecent and up-to-date standards forinternational environmental conduct.

In the Rio Declaration, Principle 10establishes the principle of public partici-pation in environmental decision-making.This principle affirms the right of eachcitizen to have access to environmentalinformation held by national publicauthorities. It stresses the duty of Statesto facilitate citizen participation byproviding that information to the public.Of particular importance to the recentinternational movement towards thedevelopment of PRTRs is Chapter 19 ofAgenda 21. Section 19.50 of Agenda 21encourages industry to recognize itsresponsibility to provide information onpotential risks and waste managementpractices associated with the trade ofchemical products. It also encouragesindustry to adopt voluntary programsrecognizing the community’s right toenvironmental information, includingthe preparation of reports on annualreleases of toxic chemicals into theenvironment. Other sections of Chapter19 in Agenda 21 — such as 19.40 (b),19.44. 19.49 (b) and 19.61 (a) — allencourage governments directly orindirectly to implement emissionsinventories.

Pursuant to Agenda 21, the Council ofthe Organization for Economic Coopera-tion and Development (OECD) issued arecommendation in February 1996 thatits member countries implement PRTR

paragraph 5 of Article 10 in the 1993North American Free Trade Agreementon Environmental Cooperation. Thisstipulates that the Council of the CECshall promote and, as appropriate, developrecommendations regarding:

“(a) public access to informationconcerning the information that isheld by public authorities of eachParty, including information onhazardous materials and activities inits communities, and opportunity toparticipate in decision-making processesrelated to such public access…”

2.2 ACTIVITIES OFINTERNATIONALAGENCIES

The strong recommendations of Chapter19 in Agenda 21 have resulted in numerousactivities to stimulate the developmentof national PRTRs. One of the mostimportant activities is the developmentof a PRTR guidance document for govern-ments by the OECD through a series ofbroadly attended workshops. The finalOECD Guidance Manual for Governments:A Tool for Environmental Policy andSustainable Development (OENE/GD(96)32)includes discussion on:

• the usefulness of instituting a national PRTR;

• developing a list of chemicals;• data management and estimation;• dissemination and use of PRTR data

and results; and• formulating a practical PRTR.

The OECD has also passed a recommenda-tion in February 1996 suggesting thatmember countries adopt a PRTR. Thisresolution will further the encourage thedevelopment and implementation ofnew PRTRs.

The United Nations EnvironmentProgramme (UNEP) has recentlydeveloped a prototype internationalPRTR web page on the Internet(http://irptc.unep.ch/prtr/welcome.html.)Designed to provide information oninternational, governmental, industrial,and non governmental organization(NGO) PRTR activities, the page willbe fully implemented in the near future.Furthermore, the United NationsInstitute for Training and Research(UNITAR) is supporting pilot projectsin three countries, including Mexico. Toassist the pilot projects and other interestedcountries, UNITAR has developed a setof guidance and training materials, comple-mentary to the OECD Guidance forGovernments manual, on the process ofdeveloping a national PRTR system aswell as on specific aspects of PRTRdesign and implementation. Otherinternational organizations, such as theInternational Program on ChemicalSafety, the United Nations IndustrialDevelopment Organization, and UNEP,are also actively involved.

Mexico and the US co-chaired theMarch 1996 meeting of the IntersessionalGroup of the Intergovernmental Forumon Chemical Safety, which reviewed thepresent status of PRTRs and highlightedMexico’s recent progress on them. TheGroup also recommended that a discussionand draft recommendations on PRTRsbe reviewed by the full membership ofthe Intergovernmental Forum at theupcoming 1997 meeting.

2.3 PRTR PROGRAMAPPROACHES INOTHER COUNTRIES

PRTRs in other countries are based onsignificantly different approaches thanthe three North American PRTRs. The

Netherlands’ registry, for example, beganas an effort to compile comprehensiveinformation on air pollution sources. Thisincluded assessments of industrial facilityemissions, but also engineering estimatesof small diffuse sources. More recently,this inventory has been expanded by theaddition of water discharge data, and theaddition of waste data is being considered.Thus, it is far more comprehensive withrespect to some sources than the NorthAmerican PRTRs, but is not fullymultimedia in its scope.

Great Britain’s PRTR is based on its permitsystem, which is being integrated acrossall environmental media. Reporting isdetermined by permit requirements.This mode of reporting is directly usefulin the British pollution control system,more so than the North American PRTRs,which include many chemicals but noregulatory limits. However, unlike theNorth American systems, the Britishsystem contains data on chemical releasesonly to the environment media forwhich permits have been issued. Thus,data are not consistent from one facilityto the next and often do not include allmedia at a particular facility. In addition,many of the substances reported in theUnited Kingdom are not individualchemicals but rather complex mixtures(e.g., volatile organic hydrocarbons) orenvironmental engineering parameters(e.g., biological oxygen demand).

Other countries’ reporting systems differin other ways. The Swedish PRTR pilotproject includes chemical use data,Norway’s PRTR tracks only 40 chemicalsand the proposed second phase of aCzech Republic inventory includes bothuse and waste generation data. TheAustralian PRTR may collect differentdata in each of its states, reflecting itsparticular governmental structure andthe diversity of sources and environmentalpriorities across the country.

2.4 PRIVATE-SECTOR INITIATIVES

Complementing these internationalactivities for greater disclosure of envi-ronmental information is a movementtowards increased self-auditing and third-party auditing of companies’ environmen-tal performance, with the results madepublicly available. Because a PRTR canprovide a measure of corporate perfor-mance, this auditing movement contri-butes to the impetus for PRTRs. Severalmajor private-sector initiatives to increasepublic disclosure of environmental datahave recently been undertaken, as follows.

• The Public Environmental ReportingInitiative (PERI),9 initiated in 1994by ten major multinational corpora-tions, outlines the type of informationthat signatories agree to make publicfor their worldwide operations.

• The Coalition for EnvironmentallyResponsible Economies (CERES)10

asks companies to respond to questionson specific social and environmentalissues.

• The European Chemical IndustryCouncil (CEFIC) published Guidelineson Environmental Reporting for theEuropean Chemical Industry.11

• The National Emissions ReductionMasterplan, initiated by the CanadianChemical Producers’ Association,requires reporting of releases andtransfers as a condition of membership.

• Corporate environmental reports areprepared and widely distributed bywell over 100 major multinationalcompanies.

• Development of environmentalmanagement consensus standards(especially the International StandardsOrganization’s 14000 Series) is ongoing.

These private-sector initiatives, combinedwith international, bilateral and nationalactivities, all increase the availability ofenvironmental information to citizens.

This chapter provides an overview andexamines the comparability of the pol-lutant release and transfer programs inthe United States, Canada, and theproposed program in Mexico.

3.1 NORTH AMERICANPOLLUTANT RELEASE ANDTRANSFER REGISTERS(PRTRS)

3.1.1 The US Toxic ReleaseInventory (TRI)

The US TRI, the oldest of the threeNorth American PRTRs, first collectedinformation on releases and transfersfrom manufacturing facilities in 1987.Additional data for on-site waste genera-tion were first reported for the year 1991.Facilities owned by the federal governmentreported for the year 1994.

The US TRI reporting is part of theEmergency Planning and CommunityRight-to-Know Act, which is based onthe principle that citizens have a “right-to-know” about hazardous and toxicchemicals in their communities. Thedata are reported to the federal and stategovernments. Some states supplementtheir TRI reports with more detailed data,including data on chemical use and sourcereduction.

The recent Presidential State of theUnion address supported the principlesof “community right-to-know” regardingtoxic chemicals. President Clinton said:“We must strengthen community right-to-know laws requiring polluters to disclosetheir emissions, but you have to use the

information to work with business to cutpollution. People do have a right to knowthat their air and water are safe”.

The list of toxic chemicals to be reportedto the TRI was compiled from state listsof hazardous chemicals used in manufac-turing. The original list had 309 chemicalsand 20 categories. Chemical categoriesare groups of closely-related chemicals,such as zinc compounds, that are reportedas a single amount. Substances havebeen added and deleted from the list asthe EPA reassesses chemicals based onacute human health effects, carcinogenicityor other chronic human health effects,and/or their adverse effects on theenvironment. For the 1994 list, 346chemicals and 22 chemical categorieswere reported (see Appendix A).

TRI ExpansionThe EPA has developed a three-phaseexpansion approach. Phase One wasimplemented in November 1994 whenthe EPA issued a final rule (40 CFR372.65, 59 Federal Register 61431)adding 286 chemicals to the TRI list,including 160 pesticides. To develop thenew list of chemicals for this first phase,the EPA examined lists of chemicalspreviously regulated or identified asbeing of concern under several environ-mental statutes. Initial reporting onthese chemicals is required for the year1995 with reports due by 1 July 1996.

The expansion to include new chemicalsin TRI reporting has been under attackin Congress and elsewhere. A bill (S. 343),sponsored by Senators Robert Dole, J.Bennett Johnston and Trent Lott, proposedto drop the 286 new chemicals unlessEPA could prove that dropping themwould jeopardize human health or theenvironment. This would require EPA toperform a risk assessment on eachchemical within 60 days. The bill remains

Programs in North America

11Comparative Review of Pollutant Release and Transfer Programs in North America

The primary purpose of the TRI is“community right-to-know”. When informedabout toxic chemicals, citizens can playan important role in helping their commu-nities achieve tangible results in protectingpublic health and the environment.

Page 22: PUTTING THE PIECES TOGETHER...Putting the Pieces Together iii Retail Price: $20.00 US Diskettes: $15.00 US For more information, contact: Secretariat of the Commission for Environmental

under discussion. In September 1995, theChemical Manufacturers’ Associationfiled a lawsuit challenging the EPA’sapplication of screening criteria in theselection of 156 of the 286 chemicalsadded to TRI. Three other chemicalindustries filed suits challenging thespecific listing of three chemicals. AnApril 1996 decision ruled in EPA’s favourand dismissed the lawsuits. Reporting forthe 286 chemicals remains effective forthe 1995 reporting year.

Phase Two of the expansion proposes toincrease the number of industries requiredto report. For the first time, non-manufac-turing industries, which may include thoseinvolved in energy production, materialsdistribution, materials extraction and wastemanagement, would report to TRI. Theproposed approach would add “sectors”within these industrial categories that arerelated to manufacturing and are respon-sible for significant releases of toxic chemi-cals. Phase Two is still under discussion.

Phase Three would expand the type ofinformation gathered. Options for thisphase include a full or partial “materialsaccounting”, adding a data element suchas the quantity of source reduction, ordoing nothing. Full materials accountingwould require an industry to report on the:

• amount of chemical brought on-site,and the amount put into or removedfrom inventory;

• amount of pollutant produced and/orconsumed during the productionprocess;

• amount of chemical shipped in orincorporated as product; and

• amount generated as waste.

Partial materials accounting would requiresome but not all of this information tobe reported. Phase Three is still underdiscussion.

In addition to the TRI expansion, EPAhas established an “alternative thresholdfor facilities with low annual reportableamounts” in an effort to make it easierfor small businesses to comply (40 CFR372.10, 372.22, 372.25, 372.27, 372.95,59 Federal Register 61488). A facilitythat does not exceed 500 pounds ofproduction-related waste of a chemicaland does not manufacture, process, orotherwise use more than 1 million poundsof that chemical does not have to reportfor it. This rule is also effective for the1995 reporting year with reports due by1 July 1996.

3.1.2 The Canadian NationalPollutant ReleaseInventory (NPRI)

The Canadian NPRI is a national, publiclyaccessible database of pollutant releasesand transfers from industrial and trans-portation sources. Under NPRI, facilitieswere first required to submit informationon releases and transfers of 178 pollutantsfor the year 1993. The first summaryreport was issued in April 1995.1

The 178 chemicals and 14 chemicalcategories to be reported under NPRI(see Appendix A) were selected followinga review of the lists used by the TRI andthe Canadian Chemical Producers’ Asso-ciation’s National Emissions ReductionMasterplan (NERM). Substances already

12 Putting the Pieces Together

According to the Multi-stakeholder Committee,the purpose of the NPRI is to help:

• identify priorities for action;• encourage voluntary action to reduce

releases;• track progress in reducing releases;• improve public understanding; and• support targetted regulatory initiatives.1

regulated or scheduled for bans and phase-outs were deleted. Substances appearingin quantities of less than one tonne onthe Domestic Substances list, whichidentifies all substances in commercialuse in Canada, were also deleted. Anadditional ten lists from other regulatoryprograms were also reviewed, and 78“candidate” substances were identifiedfor possible inclusion in future years.

Of the 178 listed substances on the NPRIlist, 53 were not released or transferredin sufficient quantities to require reportingin 1993. Environment Canada will reviewthese substances before proposing changesto the list.

Having analyzed the first year of reporteddata, Environment Canada is anticipatingsmoother data verification proceduresthis year. The responsibility for collectingand verifying the data has shifted fromthe national to the regional offices. Similarto the experience with TRI, the mostcommon errors noted in 1993 NPRIreporting were inaccurate latitude andlongitude (40 percent of the locations),confusion between recycling and transfers

in waste, and unnecessary reporting ofmineral acid releases at high pHs.

Review of the CanadianEnvironmental Protection Act(CEPA)Potential reform to NPRI is part of thereview of the primary federal environ-mental legislation, CEPA. CEPA hasbeen the subject of extensive consultationsand a review by the federal StandingCommittee on the Environment andSustainable Development.2 In December1995, the federal government issued aresponse to the Standing Committee’srecommendations. The public was invitedto comment on the government’s CEPAproposals during a 90-day period thatended in March 1996. Based on commentsreceived, the renewed CEPA legislationis planned for introduction in the fall of1996. Several of the government’s proposalsmay affect NPRI. These are:

• shifting the focus towards minimizingor avoiding the creation of pollutantsand wastes;

• broadening NPRI to provide a meansfor industry to report on pollutionprevention activities;

• creating an explicit statutory basis for NPRI; and

• creating a multi-stakeholderconsultative process to guide thefurther development of NPRI.3

The Standing Committee’s view wasthat NPRI could play a key role inpollution prevention efforts. NPRIwould be broadened considerably torequire information on:

• pollutants released into the wastestream prior to being treated, recycledor incinerated;

• pollutants transferred off-site fortreatment, storage or disposal;

13Comparative Review of Pollutant Release and Transfer Programs in North America

Several changes have been made to the1994 NPRI reporting requirements:

• addition of public liaison and companycoordinators;

• clarification of information to be submittedon the parent company;

• use of only one Canadian and USStandard Industry Classification (SIC)Code, compared to up to five codes inthe past;

• reporting on reuse, recovery, andrecycling was made optional;

• addition of two new transfer treatmentmethods — biological and chemicaltreatment;

• clarification of the definition of “waste”;• improved location codes to indicate

errors; and• deletion of chloromethyl methyl ether

and the addition of i-butyl alcohol.

Page 24: PUTTING THE PIECES TOGETHER...Putting the Pieces Together iii Retail Price: $20.00 US Diskettes: $15.00 US For more information, contact: Secretariat of the Commission for Environmental

• quantities of pollutants generated, usedand stored at facilities; and

• details of the pollution preventioninitiatives undertaken with respect tothe listed pollutants, including pollutionprevention plans and source reductionstrategies.

The Standing Committee noted industry’sgeneral support of the current NPRI andits objections to expanding it. Industrysuggested that reporting throughout thelifecycle of a substance may not have anyrelationship to environmental improve-ments, and that adding additional elementsmay make NPRI less comprehensible tothe public and more costly and complexfor industry and government.

The Committee also made a number ofother recommendations, including:

• requiring specialized reporting on keypollutants such as pesticides, ozonedepleters, and climate change gases;

• lowering the reporting threshold to4.5 tonnes;

• gradually phasing-out exemptions; and• harmonizing the NPRI as much as

possible with the TRI.

In the government’s response to theStanding Committee’s report, only thepollution prevention recommendationwas addressed. The government proposesto revise the NPRI to provide a meansfor industry to report on pollutionprevention activities.

The authority for implementing NPRI iscurrently Section 16 of CEPA. However,the multi-stakeholder committee thatfirst designed NPRI and the StandingCommittee both recommended a specificlegislative authority for NPRI. The govern-ment proposes to enshrine the NPRI inCEPA through the use of a new Ministerial

power to gather a variety of information.This change would clarify rules governingoperation of NPRI, be more appropriatefor an inventory with an annual reportingcycle and remove some of the limitationsof NPRI.

The multi-stakeholder committee andthe Standing Committee recommendedthat additional discussion on NPRI bepursued through a consultation procedure.In response, the government proposes touse multi-stakeholder consultation forchanges in NPRI. The changes in NPRIwhich may be the subject of consultationinclude: reviewing changes to the list ofsubstances, reviewing the criteria forreporting, determining how to incorporatepollution prevention activities, andreviewing the voluntary reporting ofmaterial sent for off-site recycling.

Other ActivitiesIn January 1996, Environment Canadareleased a comparison between 1993NPRI and 1992 TRI data in the GreatLakes Basin.4 The major findings of thereport were a total release of 173,092tonnes of pollutants to the Basin, withapproximately 70 percent originating inthe US and 30 percent from Canadianindustry. Over 70 percent of the totalreleases were to air. Land releases accountedfor 15 percent and underground injectionapproximately 8 percent, with waterreleases making up the smallest compo-nent, at approximately 3 percent. Thetop 25 facilities generated approximately40 percent of all releases within the Basin,and were mainly from the primary metals,and the chemical and allied-productssectors. The top 15 pollutants accountedfor approximately 73 percent of the totalBasin releases.

The environmental staff of Canada, theUS and Mexico are exchanging informa-

tion to increase understanding and com-patibility among the three systems. Forexample, Mexican staff recently visitedCanada to learn more about softwarereporting systems.

Statistics Canada, with its counterpartsin the US and Mexico, is developing aNorth American Industry ClassificationSystem, which would standardize theindustrial SIC codes used to describefacilities. Thirty-one agreements withUS and Mexico are now being finalized(available at http://www.stats.ca). Forsome sectors, such as construction, utilitiesand waste management, consensus wasnot possible, and no common NorthAmerican Code could be developed. Forother sectors, a four-digit code, along witha fifth digit for national detail, is suggested.Canada and the US plan to use the codesstarting with the annual business surveysin 1997, with Mexico implementing thesystem in 1998 to 2000.

The common set of industries are acombination of American and Canadianindustries reporting a US SIC codebetween 20-39.

3.1.3 The Mexican Registro deEmisiones y Transferenciade Contaminantes (RETC)

Mexico is in the exciting process ofdeveloping its own PRTR system, theRETC. This chapter reflects the status ofthat development as of March 1996.

The basis for the RETC is found inChapter 19 of Agenda 21 of the EarthSummit, signed by Mexico in 1992. Mexico

is participating with the United NationsInstitute for Training and Research(UNITAR) to establish and assess thefeasibility of developing PRTR systems.Egypt and the Czech Republic are alsoparticipating with UNITAR. A UNITARadvisor, stationed in the offices of theInstituto Nacional de Ecología (INE),National Institute for Ecology, providestechnical support. In Mexico, the INE isresponsible for implementing the RETC.The institute is leading the GrupoNacional Coordinador (GNC), NationalCoordinating Group, a group of approx-imately 80 government agencies, industryrepresentatives, academicians, and NGOscharged with developing the RETC.

This project will, among other benefits,stimulate discussion in industry and

government on the prevention andcontrol of pollution, provide the publicwith information on substances withpotential human health and environ-mental impacts, and serve as an importanttool for environmental policy planning.

The development of the RETC isscheduled to be completed by July 1996(see Table 3).

In the first half of 1996, the proposedRETC was tested in the State of Querétaro.This trial evaluated the operation of alltechnical, administrative and operationalaspects involved in a PRTR including the:

• list of substances subject to reporting;• reporting forms and data collection;• public use of collected information;

• necessary hardware/softwareinfrastructure;

• medium of data dissemination andpublic consultation;

• required level of inter-ministerialcooperation;

• industry participation; and• operative costs for government and

industry.

The State of Querétaro was chosen forthe case study because of its well-developedindustrial and environmental managementinfrastructure. The state’s industrial censuswas used to select industries. These werethen formally invited to participate inJanuary 1996. The list of participatingindustries is presented in Appendix B.

At present, there is no legal requirementto submit the RETC information, so thecase study relied on voluntary participationof the invited industries. A workshop toassist industries in reporting was held inFebruary 1996. Another one for stategovernment officials was at the same timewith the support of UNITAR, withrepresentatives from the EPA and theState of New Jersey participating andproviding guidance to the Mexican officials.

17Comparative Review of Pollutant Release and Transfer Programs in North America

Objectives of the Mexican RETC:

• Provide information on the emissionsof chemical substances posing risks tohuman health and the environment, andfacilitate risk assessment and itsdisclosure.

• Provide a database of reliable andupdated information quantifying releasesand transfers of specific pollutants toair, water and soil to assist in decisionmaking and the formulation of environ-mental policies in Mexico.

• Allow follow-up and quantification ofprogress in reducing releases andtransfers of pollutants to environmentalmedia (air, water and soil).

• Simplify industrial reporting requirementsand information gathering concerningthe release and transfer of specificpollutants.

• Provide additional information toassist industries in making decisionsthat complement their processes andenvironmental management priorities.

• Enable Mexico to better meet its interna-tional commitments on environmentalinformation.

• Develop a pollutant-emissions informa-tion system to serve as the basis forinformation reports that are accessibleand available to the general public.

The reporting form for the case studyhas been adapted from the US TRI, theCanadian NPRI forms, and the WorldWildlife Fund Benchmark. A guidancedocument has also been prepared. Theversion of the reporting format that wasutilized in the case study is presented inAppendix C.

The selection of the substances for theRETC case study first took into accountchemicals that were already regulated underthe Normas Oficiales Mexicanas (NOMs),official standards. NOMs establish themaximum allowable emissions to the air,water or as components of hazardous wastes.Substances listed under other PRTRprograms, such as the NPRI, TRI, theSwedish Sunset Project for Chemicals(KEMI Report), and the priority lists ofsome OECD countries, were then reviewedfor possible inclusion. These two stepsyielded a list of 407 substances.

Criteria relating to toxicity, environmentalpersistence and the bioaccumulation ofthese substances were applied, reducingthe number of chemicals on the list. Othersubstances were added, named in inter-national agreements signed by Mexico aswell as in industrial operating permits andlicences, and in greenhouse gases. A listof 132 chemicals and 17 categories reachedby consensus of the GNC members wasused for the case study (see AppendixA). Many of the chemicals released ingreatest quantities in the US and Canadaare not included on the Mexican list. Somechemicals released in high volumes, suchas methyl ethyl ketone, that appear onthe American and Canadian lists, do notappear on the Mexican list because theydo not meet Mexico’s specific toxicity,bioaccumulation and persistence criteria.

The GNC agreed that reporting thresholdswould not apply to the case study. Indus-

tries were expected to report on eachlisted pollutant that is released or trans-ferred. Existing material on data-estimationmethods produced by the EPA, UNITAR,and World Health Organization (WHO)was used as guidance during the case study.For the national RETC, special manualswill be developed.

Data gathered in the case study will beused to conduct a general assessment ofreleases and transfers of chemical sub-stances by industry, and their potentialimpacts in the State of Querétaro. Theinformation could be used to evaluatecurrent environmental policies andestablish priority actions.

A report analyzing the data was presentedto the GNC in July 1996 to assist in thedevelopment of the RETC. Based on thisdata and experience, threshold limits maybe designated, the list of substances andthe report format modified, the size andtype of industries required to reportdetermined, and other elements of thenational RETC reconsidered.

3.2 COMPARATIVE OVERVIEWOF NORTH AMERICANPRTRS

The North American PRTRs collect dataon the releases and transfers of chemicalson an annual basis.

18 Putting the Pieces Together

The major elements of the NorthAmerican PRTRs are:

• identification of facilities andchemicals;

• reporting thresholds;• type of releases reported;• type of transfers reported;• chemicals in waste; and• other data elements, including source

reduction activities.

This section compares the majorelements of a PRTR in each country.Table 4 shows how the major dataelements are reported under eachcountry’s PRTR.

Note: CMAP refers to the ClasificaciónMexicana de Actividades y Productos(CMAP), Mexican Classification ofActivities and Products.

3.3 COMPARABILITY OF THEDATA

This section compares the PRTRs ineach country and proposes ways to fitthe pieces of information together.

3.3.1 Comparability ofIdentification and Threshold ReportingIdentification of Facilities

Individual facilities are identified bylocation and industrial sector. Each ofthe three PRTRs require the facilityname, address and a type of SIC code(see below) and the name of the parentcompany. However, facility and parent-company names and addresses are notstandardized. Slight differences in spellingor abbreviation make it difficult tocompare parent-company data acrossNorth America.

All three countries also ask for otheridentification numbers assigned by govern-ment programs. This helps to link therelease/transfer data to other types ofenvironmental data and expands theusefulness and scope of the PRTR. Identifi-cation numbers also help to match dataon a facility or parent company basis.

Industrial ClassificationStandard industrial classification (SIC)codes are used to group and comparesimilar facilities. All three countries

require reporting of the type of SIC codefor a facility, but the codes are differentin each country. For example, theCanadian SIC code for the IndustrialInorganic Chemicals Industry is 3711,whereas the closest American match isUS SIC code 2819 (also defined asIndustrial Inorganic Chemicals).American and Canadian data can becompared because the Canadian NPRIrequires reporting of both country’s SICcodes. The American code can then becompared with TRI data.

The Mexican industry classificationsystem is the Clasificación Mexicana deActividades y Productos (CMAP), MexicanClassification of Activities and Products.Although this industrial classificationsystem is similar in concept to those inCanada and the US, it is not directlycomparable, just as the Canadian systemis not comparable to the American one.Two conditions need to be overcomebefore Mexican data can be combinedwith American and Canadian data:development of a concordance tablebetween Mexican CMAP and US SICcodes, and adding of the requirement toreport the latter on the Mexican form.Without the two events happening,Mexican data cannot be easily used withother North American data.

In addition to the differences betweenthe systems in the type of SIC code used,each system also requires different typesof industries to report. NPRI covers anyfacility manufacturing, processing, or usinga listed chemical. Exemptions exist forresearch, mining and extraction operations,as well as wholesale and retail sales ofproducts containing the substances. TheTRI covers only manufacturing and federalfacilities. Mexico is still discussing thetype of industries that will be required toreport. A North America-wide dataanalysis could be based only on the set of

19Comparative Review of Pollutant Release and Transfer Programs in North America

facilities common to the three systems,which presently would be drawn mainlyfrom the manufacturing sector.

The TRI requires reporting of all SIC codesapplicable to the operations involvingthe listed chemicals. The Canadian NPRIused this same system in 1993, but hassubsequently changed to a single SICcode that “describes the highest value ofactivities” at the facility. The proposedMexican RETC contemplates reportingonly one CMAP code as well.

The change to reporting only one SICcode will make a North American analysiseven more difficult. For example, in the1993 TRI, facilities with operationscovering more than one major SIC code

(such as an oil refinery and chemicalmanufacturing plant combined at onelocation), represent 6 percent of releasesand 10 percent of transfers. Assigningreleases and transfers to just one SICcode would increase the apparent releasesand transfers of that one SIC code whileunderestimating another. The CanadianNPRI allows large refining and petro-chemical sites, which are adjacent toand owned by the same company butoperated as different business units, toreport separately. This would reduce theassigning of releases and transfers to anincorrect SIC code.

Activity and/or Use IndicatorReporting how a substance is used at afacility is useful because releases and

transfers can be dependent on how thatsubstance is used within a facility. Forexample, higher volumes of releases andtransfers would be expected from a plantwhere a chemical is used as solventrather than being manufactured. Allthree systems ask a facility to indicatehow each reported chemical is used.Since the definitions of “manufactured,processed, or otherwise used” are thesame, the Canadian, US, and proposedMexican data can be compared.

Chemical ClassificationAll three North American PRTRs arebased on reporting amounts for individualchemicals which are identified by aChemical Abstracts Service (CAS)number. The CAS number is an impor-

tant identifier: although chemicals haveonly one number, they can have severaldifferent names. (See Appendix A for acomparison of the three lists of chemicals.)Using the CAS number, chemicalcomparisons among the three systemscan be made.

In addition, each country groups similarindividual chemicals into categories. Eachcountry has different categories: the US has22 categories, Canada has 14 and Mexicois proposing 17. A North American analysiscan be made by regrouping the individualchemicals into common categories.

Threshold for ReportingBoth the US and Canada require reportingif specific threshold quantities are exceeded.

If these are met, then all releases andtransfers must be reported. Mexico isstill discussing thresholds for the RETCand has agreed that no threshold will beused for the case study. This allows datato be collected to help determine thefinal threshold. However, the thresholdsdiffer between the US and Canada. Underthe US system, a report must be submittedif the chemical is manufactured orprocessed in excess of 25,000 pounds(11.34 tonnes) or otherwise used inexcess of 10,000 pounds (4.54 tonnes).Under the Canadian system, a reportmust be submitted if the facility hasmanufactured, processed, or otherwiseused 10 tonnes (22,050 pounds) or moreof the substance. Both systems exemptfacilities that employ the equivalent offewer than ten full-time employees.

In addition, beginning with the 1995reporting year, the TRI will have an“alternate threshold” that will exemptfacilities from reporting a chemical thatdoes not exceed 500 pounds (0.226tonnes) in waste. This criteria applies ifthe facility does not manufacture, processor otherwise use in excess of 1 millionpounds (454 tonnes) of the chemical.

Both countries also have exemptions fora chemical present in a mixture. If thesubstance is present in concentrationsgreater than or equal to 1 percent byweight, it must be reported. The USrequires, in addition, reporting of certainlisted substances at the de minimis levelof 0.1 percent if the chemical meets theUS Occupational Safety and HealthAct (OSHA) carcinogen standard. Thus,in general, US facilities will meet thethreshold requirements at lower levels ofchemical activity and/or use thanCanadian ones.

The difference in threshold requirementsis hard to account for when comparing

the two systems. If one country has moresmall- and medium-sized industries thatdo not reach the threshold for reporting,then each PRTR will represent a differentpercentage of the total releases andtransfers.

The US has estimated that changing toa higher 10-tonne, “otherwise used” thresh-old, similar to the Canadian system, wouldreduce reported releases by only 2 percent.5

On the other hand, the Canadian analysisof NPRI and TRI data in the Great LakesBasin considered that the higher US“manufacture and process” thresholdscause that country’s releases and transfersto be “marginally under-estimated.”6 Theeffect of the lower US alternate thresholdand lower carcinogen threshold is alsohard to judge. In the North Americananalysis, the difference in thresholdsbetween the systems will be pointed outas a reason to interpret the data carefully.

3.3.2 Comparability of Reporting Categories

Facilities meeting the threshold criteriafor any listed chemical are required toreport estimates of releases and theamount of the chemical in off-sitetransfers of waste. Amounts can beestimated using direct measurements,mass balance, emission factors, orengineering estimates. Each country’sPRTR directs the facility to indicatehow release estimates were made, usingthe same estimation categories.

The amounts of pollutants are reportedin tonnes to the Canadian NPRI (allowingfor quantities as small as one kilogram),in pounds to the US TRI, and in kilogramsto the proposed Mexican RETC. Theamounts will be converted to kilogramsin a comparative analysis by the CEC.

Estimates of On-site ReleasesTable 4 shows the types of releases reportedunder each country’s system. While thetotal releases are divided into differentsubcategories, total air emissions, surfacewater discharges, and on-site land releasescan be compared. Canada and the USalso report on on-site undergroundinjection. The proposed Mexican RETCdoes not have this category since thereare no underground injection wells inMexico.

Accidental spills are treated differentlyin each country. For the Canadian system,they are reported as a separate item foreach type of release. Under the US TRI,accidental spills are included in eachtype of release but not broken-out. In aseparate section of the American formare reported the total volumes from allnon-production leaks and spills, as wellas wastes from remedial actions. Underthe proposed Mexican system, accidentalspills would be considered separatelyfrom normal operating releases. If thesespills were added to the total releases, it would mask some of the pollution-prevention activities affecting the normalreleases. Also, spills often involve morethan one medium, so the proposedMexican form has accidental spills reportedseparately by medium. A North America-wide analysis will include spills whencomparing releases.

In addition to the differing release cate-gories, both the American and Canadiansystems use a series of range codes thatcan be chosen for small releases. Smallreleases are defined as less than one tonne(2,205 pounds) under NPRI, and lessthan 1,000 pounds (0.45 tonnes) underTRI. When adding these releases to theother quantities, the midpoint of therange is used in both the NPRI and theTRI summary reports. In addition, theNPRI allows releases amounting to less

than one tonne (2,205 pounds) to betotalled without any breakdown betweenair, water, land, or underground injection.The actual amount (or estimate) of allreleases are to be reported under theproposed Mexican RETC. This differingtreatment of small releases could affectcomparisons made between the twodatabases if the subsets being comparedhad only small releases. However, overthe entire database the effect is small. Inthe Canadian database, for example, smallair releases accounted for less than 0.03percent of the total releases. In the TRIthe reports with range codes represent0.01 percent of the fugitive air emissionsreported.

Estimates of Off-site TransfersOff-site transfers of chemicals in wasteare reported for each chemical. Only thequantity of the pollutant in the waste isreported, rather than the total quantityof waste material.

All three systems require reporting thename and address of the off-site transferlocation. However, while the US andMexican systems require the amount ofthe transfers to be reported for eachtransfer site, the Canadian one does not;it requires only a total amount accordingto method of treatment or disposal. There-fore, it is not possible to get amounts ofCanadian transfers sent to various geo-graphical points within and from Canada,for example, the amounts sent to the USfrom Canada. However, it will be possibleto know the amounts of transfers sentfrom the US to Canada or Mexico, andfrom Mexico to the US or Canada. But,since there is no standardization ofplacenames or addresses it will requirechecking of individual reports to analyzewhere wastes are going.

While each country’s system has differentcategories for reporting the type of transfer,

23Comparative Review of Pollutant Release and Transfer Programs in North America

Page 34: PUTTING THE PIECES TOGETHER...Putting the Pieces Together iii Retail Price: $20.00 US Diskettes: $15.00 US For more information, contact: Secretariat of the Commission for Environmental

they can be summed up into broad cate-gories: transfers to public sewage systems,transfers to treatment, transfers to disposal.In addition, since 1991 both the Americanand the Mexican systems require reportingof transfers to recycling and energyrecovery facilities. Because of difficultieswith the NPRI definition of waste in 1993,and with companies using different wastedefinitions, the quantity of substancesreported under recycling, reuse, andrecovery will not be an accurate estimate.For 1994, the definition of waste has beenclarified as “material that is sent for finaldisposal or treatment prior to disposal”.Therefore, recycled, reused, or recoveredmaterials are not considered a waste, andare not required to be reported to NPRI.A facility may wish to provide this infor-mation voluntarily, but unlike TRI andthe proposed RETC, reporting on recycling,reuse, and recovery is not obligatory.Therefore, any comparisons of the twosystems will have to separate the type ofoff-site transfers. This is already done inthe annual TRI report and also in theCanadian report for 1993.

Chemicals in Waste Managed On-siteSince 1991, under the Pollution PreventionAct, the TRI has required reporting ofchemicals in waste that is managed on-site.This includes chemicals that are recycled,used for energy recovery, and treated on-site. This section of the TRI was added toreflect the environmental managementhierarchy of priorities for addressingindustrial waste problems. This hierarchyhas prevention of pollution at the sourceas its top priority, followed by recyclingand/or recovery, and waste treatment,with waste disposal as the least desirablemanagement option.

The Canadian NPRI does not requirereporting of chemicals in any wastemanaged on-site, so comparison of these

amounts is not possible. The proposedMexican RETC includes on-site wastemanagement by type of treatment andphysical state, but does not ask forchemical amounts in on-site treatedwastes. On-site recycling, reuse, andrecovery are considered waste treatmentmethods in Mexico.

Future ProjectionsBoth the American and Canadian systemsrequire projections of the amounts ofreleases and transfers. The US TRI hasprojections only for the next two yearswhile the Canadian database projectsthree years into the future, with fourthand fifth years being optional. The devel-oping Mexican RETC has projectionsfor the next year. The Canadian projec-tions are in two parts, total releases andtotal transfers. The US projections haveseven categories: total releases plus transfersto disposal as one number, on-site andtransfers to treatment, on-site andtransfers to recycling, and on-site andtransfers to energy recovery. In addition,the US projections specifically excludeamounts for spills, leaks or remedialactions. The proposed Mexican projec-tions are for total releases only.

To compare projections, an assumptionmust be made about how Canadianfacilities project spills and leaks. Oneassumption could be that they assume aconstant level, in which case the amountof spills and leaks reported in the currentyear could be subtracted as a constantfrom all future projections. Anotherapproach would be to make no changesto the projections and note that theymay differ because of this reportingdifference.

Source ReductionThe TRI requires reporting what types ofsource reduction activities were undertakenduring the reporting year. Data are not

24 Putting the Pieces Together

Page 35: PUTTING THE PIECES TOGETHER...Putting the Pieces Together iii Retail Price: $20.00 US Diskettes: $15.00 US For more information, contact: Secretariat of the Commission for Environmental

collected concerning the amount ofchemicals in waste that may have beenreduced due to these activities. Theproposed Mexican RETC also reports on types of source reduction activitiesusing somewhat different activity cate-gories, but without giving amounts.

The Canadian NPRI does not requireany reporting on source reduction activitiesor amounts of waste reduced due to sourcereduction. It does ask for general reasonswhy the releases and transfers changedfrom the previous year. However, thereare four choices in answer to this question:changes in production levels, changes inestimation levels, other, and no significantchange. None of these specifically indicateschanges due to source reduction activityand “other” is defined as “accidents, spills,breakdowns”.

An indication of how the level of produc-tion has changed from the prior year tothe current year can be given as an activityindex. The actual level of productioninvolved with the chemical is not reported.This type of data is requested becausethe information on releases and transfersdoes not take into account the amountof production at the facility. A largefacility will have greater releases than asmaller facility if both are operating atthe same rate of release per unit of produc-tion. This lack of consideration of therate of release per unit of productionprecludes an assessment of environmentalefficiency of the facility and management.However, it should be noted that somesources of releases, such as fugitive equip-ment leaks from petroleum refineries, arenot sensitive to production levels so thata production activity index would not beappropriate for such releases.

The TRI requires a facility to report aproduction activity index for each chemicalsubstance. The production activity index

is the ratio of the production associatedwith the chemical in the current year tothe previous year’s production level. Thisindex indicates how production levelshave changed without reporting actuallevels of production. The developingMexican RETC appears to be similar tothe TRI that reports on the productionactivity index; the Canadian NPRI doesnot ask for an index.

3.3.3 Requests for Confidentiality

PRTRs include provisions that give afacility an opportunity to protect data itviews as confidential. Under the US TRI,the only type of “trade secret” claim thatcan be made is for the identity of thechemical substance. All data on amountsof releases, transfers or wastes must besupplied and are part of the public database.In the public database, a generic name issupplied for the chemical that is claimedas a trade secret. Claiming trade secrecy isnot widespread — for 1993, only 14 out ofalmost 80,000 reports were accepted trade-secret claims. The EPA routinely reviews allclaims for trade secrecy under four criteria:

1. the information has not already beendisclosed (other than to designatedofficials);

2. the information is not required to bedisclosed under any other law;

3. the information is not readily identi-fiable through reverse engineering; and

4. the claimant can show that disclosureof the information is likely to harmthe firm’s competitive position.

Under the Canadian NPRI system, anyperson may submit a written request thatthe information provided be treated asconfidential. Documentation justifyingthe request is reviewed to see if it meetsthe criteria for confidentiality under thefederal Access to Information Act. Thesecriteria are:

25Comparative Review of Pollutant Release and Transfer Programs in North America

Page 36: PUTTING THE PIECES TOGETHER...Putting the Pieces Together iii Retail Price: $20.00 US Diskettes: $15.00 US For more information, contact: Secretariat of the Commission for Environmental

• the trade secrets pertain to a thirdparty;

• financial, commercial, scientific ortechnical information has beensupplied by a third party and istreated consistently in a confidentialmanner by the third party;

• the information could reasonably beexpected to result in material financialloss or gain or prejudice the competitiveposition of a third party; and

• the information could reasonably be expected to interfere with thecontractual standing or negotiationsof a third party.

All information may then be held confi-dential, in contrast to the TRI whereonly the name of the chemical can beclaimed as trade secret. For the 1993NPRI reporting year, there were 31 tradesecret forms out of approximately 5,200reporting forms.

At present, the GNC has not reached afinal decision on confidentiality provisionsfor the Mexican database. The case studyresults are expected to discuss the extentof permissible disclosure of information.

3.3.4 Communication of Data

Both the US TRI and the Canadian NPRIdata are available to the public in a varietyof formats, including annual summaryreports as well as data tables and databasesin electronic form, including the Internet(see Section 4.2, Figure 2, for Internetaddresses). The RETC information willbe available to government and academicinstitutions, industry, non-governmentalorganizations, and the public. However, thelevel and detail of the information to bemade public has not yet been decided.

3.4 CONTEXT OF THE DATA

The American, Canadian, and proposedMexican systems do have many commondata elements which make comparisonsof releases and transfers possible. Whenputting the data together across NorthAmerica, it is important to consider itscontext. As discussed below, most PRTRsystems do not provide estimates of:

• all releases and transfers from a facility;• pollutants released from non-point

sources such as transportation;• pollutants released from small sources;• pollutants released from a full range

of industrial facilities;• chemical use;• factors responsible for changes in

releases and transfers;• releases and transfers of all chemicals

of concern;• chemical exposure or risk; and• normalized comparisons.

Accounting of All Releases andTransfers from a FacilityOne major impetus for establishing thefirst PRTRs was to get an accounting ofall releases and transfers from a facility.Without reporting on releases to allenvironmental media, it was not possibleto know if a reduction in, for example,land disposal was not accompanied by anincrease in air emissions from an incin-erator. With the advent of PRTRs, thesechanges are noted as shifts in the releasefrom one media to another rather thanreductions. On the other hand, theCanadian NPRI does allow exemptionsfrom mandatory reporting for off-sitetransfers of chemicals destined for recyclingand energy recovery, so a shift in the typeof transfer could be seen as a reduction.

26 Putting the Pieces Together

Page 37: PUTTING THE PIECES TOGETHER...Putting the Pieces Together iii Retail Price: $20.00 US Diskettes: $15.00 US For more information, contact: Secretariat of the Commission for Environmental

Full Accounting of Releases andTransfersThe North American PRTRs requirereporting from industrial facilities, withthe Canadian NPRI having a broaderbase than the US system, which onlyrequires reports from manufacturingfacilities. Less than 70 percent of releasesand transfers reported by facilities to theCanadian NPRI are from the equivalentof the manufacturing type of facilitiesthat report to the US TRI.

Another significant source of chemicalreleases is non-point sources, particularlytransportation vehicles and equipment.Information on these chemicals is notincluded in TRI or the proposed RETCdatabases. The Canadian report on theNPRI for 1993 included release estimatesfor 10 NPRI substances from mobilesources, such as automobiles, trucks,aircraft, boats, and from fuel distribution,which were ten times as great as theamounts reported to NPRI. The thresholdsrequire that only the largest users ofchemicals report to the US TRI and theCanadian NPRI. Smaller users that oftendo not meet the threshold requirements,such as dry-cleaning establishments, maybe large sources of pollutants if taken asa whole or in a particular locale. However,PRTR data can be used together withother monitoring and permit data to obtaina fuller picture of an individual facility.

Use DataChemical use data include the amountof chemicals brought on-site, the amountproduced on-site, the amount used frominventory, the amount recycled as inputto the industrial process, the amountconsumed during the production processand the amount shipped in productsproduced by the industrial process.Chemical use data are not requiredunder the TRI, NPRI, or the proposedRETC.

Reporting on the use of chemicals atindustrial facilities can serve manypurposes. Use data can be combinedwith data on wastes to provide a completepicture of the flow of a particular chemicalthrough a facility. Use data can alsoprovide information on chemicals inproducts, such as ozone-destroying CFCs.It can provide information on potentialworker exposure. Also, progress in reducingwaste and chemicals in products can betracked.

Some companies are concerned thatmaking “use data” public will discloseconfidential information about theirprocesses, products, market share, manu-facturing capacity, the marginal cost ofproduction, or business plans. Such infor-mation could then be used to damage acompany’s competitive position. When a company develops a new process orproduct, for example, the release of suchinformation could enable another companyto adopt the process or product withouthaving to expend the development costs.However, the North American PRTRshave provisions that give a company theopportunity to protect data it views asconfidential. Some American states thathave supplemented the TRI system withtheir own use reporting have found fewtrade-secrecy claims. Such claims underNew Jersey’s system, which collects infor-mation on the full materials balance, havebeen filed by no more than 5 facilities outof about 700 (0.7 percent) since 1987.

Tracking Reductions in Releases andTransfersPRTR data can track reductions in thereleases and transfers from year to year.

However, reductions can be a combinationof source reduction, production levelchanges, pollution control and changesin estimation methods. Several methodscan be used to investigate changes, but

27Comparative Review of Pollutant Release and Transfer Programs in North America

Page 38: PUTTING THE PIECES TOGETHER...Putting the Pieces Together iii Retail Price: $20.00 US Diskettes: $15.00 US For more information, contact: Secretariat of the Commission for Environmental

current PRTR reporting does not indicatehow much of the change was due to whatfactor. To track the reduction in releasesand transfers due to source reductionactivities, this information needs to bereported by the company. None of theNorth American PRTRs collect thisdata. However, the State of New Jerseydoes have some experience in reportingsource reduction activities through itssupplement to TRI.

Production level changes can changethe amount of releases and transfers,increasing the total even in the face ofsource reduction or pollution controls.The TRI and the proposed Mexican RETCdo require the reporting of a productionactivity index, but this number requirescareful interpretation and is not applicableto all types of industrial operations.

Changes in the methods of estimatingreleases and transfers can change thequantities reported. To reduce the costto industry of reporting, the data givenare estimates; facilities are not requiredto make precise measurements of theirreleases or transfers. These estimates canbe based on monitoring data, materialsbalance calculations, or best engineeringjudgement. The type of estimation methodused may change from year to year. If itdoes, then the amounts reported may alterwithout any change in the actual release.

Data on Exposure and RiskPRTRs do not collect data on eitherexposure to or risk associated withchemical releases. Strictly speaking,these types of analysis are dependent onspecific geographic and populationcharacteristics at the site, but PRTRscan provide some of the data needed tomake them. For example, public healthagencies can use the data on releases fromlocal facilities as one piece of informationto compile a picture of local exposure.

Normalized ComparisonsA number of factors need to be consideredwhen reviewing the total amounts ofchemicals released and transferred: sizeand type of the industrial base, possibleuse of pollution control equipment, andproduction levels. Some experts havesuggested that “normalizing” the data(expressing it as total amounts of chemicalsper unit of production, per job or per energyuse) would increase understanding. Forexample, the US may have high totalreleases and transfers because of its largemanufacturing sector. Expressing thereleases as chemicals per unit of produc-tion or per job would allow a comparisonadjusted for the size of the industry. Othershave suggested that these “normalized”measures have built-in assumptions thatmay not be valid. The US, Canadian, andproposed Mexican systems do not usenormalized measures.

3.5 CONCLUSIONS

The US TRI and the Canadian NPRIcontain enough comparable informationin common that meaningful compilationsof North American data are possible. Asfar as identification and classification areconcerned, they have similar reportingrequirements, they both require geograph-ical location data, the lists of chemicalsoverlap, the Canadian system providesthe US SIC codes, and they requirereporting on an annual basis.

For the amounts of the substances inreleases and transfers, the systems eachprovide different details, but releases canbe summarized into air, water, land andunderground injection categories, andtransfers summarized as transfers to publicsewage, treatment and disposal. Theproposed Mexican system can also becompared if an industry classificationscheme that translates to the US SICcode is adopted.

Comparisons of releases and transferswill be based on the set of chemicalsthat are reported to both systems, or allthree systems, once data is available fromthe Mexican RETC. Substances listed ascarcinogens on the TRI list and, therefore,subject to a lower reporting thresholdshould be highlighted in a comparisonanalysis and the differences noted, becausethe exact effect of the threshold is notpossible to determine.

For comparable chemical sets, the greatestdifference is in the facilities with smallamounts of chemicals in releases andtransfers. Each system treats thesedifferently, but the quantities involveddo not represent a significant portion ofthe total database. However, if only asubset is being compared, the analysismust determine whether the subset hasbeen produced by a disproportionatenumber of facilities with small releasesor transfers.

4.1 USES OF CANADIANNATIONAL POLLUTANTRELEASE INVENTORY(NPRI) DATA

The early uses and users of the first yearof data released under NPRI mirrors theearly TRI years. Generally, the users ofNPRI data fall into three main groups:industry, government, as well as acade-micians and NGOs.

4.1.1 Industrial Use of NPRI

As had been true of TRI, the data collectedunder NPRI gave some companies the fir s tcomprehensive picture of chemical releasesand transfers they had ever had. Oftenthe results were surprising. For example,Sunworthy Wallcoverings found it releasedand transferred 862 metric tonnes ofpollutants, and is now taking action tocapture 90 percent of the volatile chemicalsolvents in its wallpaper inks. Other com-panies, such as members of the CanadianChemical Producers’ Association, hadalready started an emission reportingsystem and so were more prepared forthe results. Some industrial associations,such as the Canadian Petroleum Prod u c t sInstitute, expressed concern over thelarge discrepancies between releases andtransfers of its members, and are workingto improve consistency in estimatingreleases. Industrial groups in Canada, asin the US, have created a number ofprograms that benefit from NPRI data.Two of these, the Responsible Care andthe Accelerated Reduction/Eliminationof Toxic (ARET) programs, are describedbelow.

The Canadian Chemical Producers’Association requires companies to reportemissions publicly as a condition ofmembership. The CCPA system predates

NPRI, has a broad list of chemicals toreport (369 chemicals in 1994), a 1 kilo-gram reporting threshold for persistent,bioaccumulative and toxic compounds,and a five year projection. In 1994, themembers achieved approximately a 35 per-cent reduction in emissions compared to1993, and a 50 percent reduction com-pared to 1992. Members are projectingthat total emissions for 1999 will be 72percent lower than amounts reported in1992. Results are publicly released in anannual report.1

The second industry-supported program,the ARET is designed to reduce or elim-inate toxic substance releases quicklythrough voluntary action.2 The ARETprocess has identified 101 chemicals andplaced these on one of five lists: A1chemicals are persistent, bioaccumulativeand toxic; A2 chemicals are those forwhich there is no ARET consensus onhow to characterize them; whereas thethree subsets of B chemicals meet thetoxicity criteria, in addition to somecriteria for persistence or bioaccumulation.The goal for the 30 A1 chemicals isvirtual elimination, beginning with a 90 percent reduction in releases by theyear 2000. The goal for the two A2chemicals and 69 B chemicals is thereduction in releases to levels which areinsufficient to cause harm. The challengefor A2 and B chemicals is a 50 percentreduction in releases by the year 2000.

In 1994, ARET challenged selectedcompanies and government departmentsto achieve these reduction targets. In itsrecent update, 207 organizations havepledged support to the program, and somehave committed to a reduction in ARETreleases of approximately 9,800 tonnesby the year 2000. Companies reportedreductions of almost 11,000 tonnes of

ARET substances at the start of the ARETchallenge. Companies submit public actionplans to ARET detailing how emissionreduction will be achieved.

ARET differs from NPRI in several ways:it has no reporting threshold, its intentis a voluntary reduction of releases,companies chose their own base year,and its list of chemicals is based on ascientific review of environmental andhealth criteria. About half of the ARETsubstances are on the NPRI list. Somecompanies use NPRI data to report toARET. NPRI is also used as a method oftracking progress on ARET goals.

NPRI is also starting to be used in a varietyof other ways. Real estate, banks andother companies are checking a facility’senvironmental record before purchasingland or lending. Legal and engineeringfirms are using NPRI data in environmentalaudits on a facility as part of an environ-mental management system. Industrialassociations are examining the records oftheir members, and vendors of pollutionprevention or control technology use theNPRI to identify prospective clients.

4.1.2 Government Use of NPRI

The data from NPRI are used by variousdepartments of the federal and provincialgovernments. For example, some chemicalswere reconsidered under the prioritysubstances listing process of the CEPAbecause of the higher than expectedemissions shown in NPRI. EnvironmentCanada uses NPRI to target key industrialsectors for pollution prevention efforts.NPRI data are also fed into discussionsof air issues. Government departmentssuch as Transport Canada are checkingtheir own releases and transfers, andformulating reduction plans with the aidof the data. Even politicians have used

NPRI data to determine releases and trans-fers from facilities in their constituencies.

Regional offices of Environment Canadaalso review NPRI data for facilities intheir area, and identify priorities for action.For example, the Ontario office of Envi-ronment Canada has prepared a summaryof total releases and loadings to the GreatLakes Basin using NPRI and TRI data.This report will assist the developmentof Lakewide Management Plans byproviding an indication of pollutantloadings to each of the Great Lakes.

Provincial governments use NPRI datain different ways. Some governments,such as Ontario, use the data to generatepictures of chemical loadings to the GreatLakes. The Ontario and federal govern-ments also use NPRI data to help trackprogress in reducing chemical releasesunder memoranda of understandingw i t h industrial groups.

4.1.3 Academic, NGO, andPublic Use of NPRI

Environment Canada receives thousandsof inquiries on the Internet and over thetelephone from universities, schools,NGOs, and the public. One school groupasked for specific information on whichcompanies were emitting a particular chem-ical, because they wished to ask themdetailed questions about their reductionplans. From April to December 1995,3,416 queries were received on the Internetdatabase. Inquiries have come from allover the globe: Australia, Mexico andGreat Britain.

Many newspapers across the country rana story on NPRI when the first year of datawere released. As had been the experiencewith TRI, many papers customized theresults to report on facilities in their locale.

32 Putting the Pieces Together

NPRI data were also used by the largestnewspaper in the country to produce anaward-winning special section on LakeOntario, and another report on theGreat Lakes.

In summary, even with only one year ofdata reported under NPRI, uses of NPRIdata are diverse and numerous. Uses and users are expected to increase asadditional years of data become availableand familiarity with the database increases.(See Figure 1 for information aboutaccessing NPRI.)

4.2 US E S O F US TOX I C RE L E A S EINVENTORY (TRI) DATA

The TRI is widely regarded as the EPA’smost important, most frequently usedenvironmental database. The CanadianNPRI and the proposed Mexican RETCdatabases are likely to grow to similarimportance. TRI was created to be publiclyavailable, but even with public accessibilityas its foundation, it is probably safe toassume that no one in government orindustry anticipated the current level ofinterest in TRI data (see Figure 2). As soonas the EPA was given the responsibilityto collect and disseminate TRI data, itsought to identify the key users and usesfor the data. However, it was rapidlyrealized that the users and their uses forTRI data were too numerous and farreaching to summarize. Therefore, theEPA built a highly structured databasewith common identifiers for most entries(i.e., standardized geographical andchemical names). The result has beenuses that were not even contemplatedwhen TRI was first enacted.

Over the eight years that TRI data havebeen collected, its uses have evolvedfrom exposure and confrontation to thebeginnings of cooperation between stake-holders. These stakeholders includeindustry, government, communities, andother organizations concerned with pro-tecting human health and the environ-ment. This chapter illustrates only a fewof the many uses of TRI data to date. Moreare emerging each year.

4 . 2 . 1 Industry and TRI Reporting

For many companies, the 1987 TRI wastheir first comprehensive record of releasesand transfers. Prior to 1987, in additionto Toxic Substances Control Act data,facilities reported various environmental

data to separate offices within EPA, mostlyon surface water discharges and hazardouswaste generation. No comprehensive sourceon facility-wide releases and transfers ofspecific chemicals was available. Somecompanies may have estimated all releasesand transfers before 1987, but these wereinternal estimates. TRI added publicaccountability.

Industry has come to see the value in publicinventory reporting, and the very fact thatTRI is public is the factor most responsiblefor the decrease in TRI releases and trans-fers since 1987. Industry groups, companiesand facilities have created a number of

programs linked directly to TRI datawhich thus provide a publicly accessibleand verifiable baseline that would nototherwise be available.

In 1988, the Chemical Manufacturers’Association (CMA) began its ResponsibleCare Program, an initiative to integrateimproved environmental managementpractices into all areas of operation inthe American chemical industry. Two ofResponsible Care’s Codes of ManagementPractices relate to TRI: The CommunityAwareness and Emergency Response Cod eexplicitly acknowledges the right-to-knowprinciple. The Pollution Prevention Cod e

Figure 2. Public Access to TRI Dataand Information

TRI was the first environmental databasemandated by statute to be accessible elec-tronically to the public. TRI data were firstmade available in 1989, both in a summaryre p o rt and through the US National Libraryof Medicine’s Toxnet computer system(301-496-6531 to register). Also in 1989,the Right-to-Know Computer Network (RTKNET) was established by two public intere s to rganizations at the Unison Institute to pro v i d eadditional access to environmental data-b a s e s. While the EPA distributes thousandsof paper copies of national summaryreports each year and has made suchreports available on the Internet, theNational Library of Medicine and RTK NETcontinue to be the two major nationalelectronic sources of TRI data. Both allowsearches on a number of geographic,chemical and other identifiers, and theiruser patterns give a glimpse of the popu-larity and utility of TRI data. Other informa-tion on use and user profiles is availablef rom the EPA, which maintains user telephonesupport of TRI, and from organizationspublishing analyses of and guides to TRIdata.

Online Data Access

RTK NET (202-234-8494 for information on free access to TRI data, or online at 202-234-8570) has approximately 3,000subscribers: 50 percent of users are NGOs,

30 percent are from representatives of thebusiness community who are seeking tomarket their services to companiessubmitting re p o rts to TRI, and the re m a i n i n g20 percent are from government, the pressand academia. RTK NET estimates that ithosted more than 21,000 TRI data searchesin 1995. The RTK NET web page is on theInternet at http://www.rtk.net.

TRI Telephone Support

The EPA’s TRI User Support (TRI-US) (800-533-0202 within the US and 202-260-1 5 3 1 outside the US) provides TRI technicals u p p o rt in the form of general information,reporting assistance and data requests.The EPA reports that requests come from amix of industry, NGOs, and individuals withspecific concerns.

Publications

A number of publications explaining theuses of TRI data have been available since1989, including guides produced by theEPA1 and Chrysler Corporation.2

“promotes industry efforts to protect theenvironment by generating less waste andreducing pollutant emissions.”3 The Cod eof Management Practices, approved in1990, requires members to implement apollution prevention program that leadsto ongoing reductions in releases and wastegeneration, and requires them to s u b m i t

their TRI data to CMA each year forreview and compilation. By publishingrelease totals each year, CMA uses TRIdata to measure progress.

Responsible Care does not require membersto adopt numerical TRI reduction goals;however, many companies are using TRIreporting to create voluntary reductiongoals. Many American company reportscontain summaries of TRI data, and atleast ten companies have set forth reduc-tion goals linked explicitly to TRI data(see Figure 3). These goals are in additionto those made for EPA’s 33/50 Program.

Companies have developed publicly-available environmental reports as ameans of providing context and explana-tion for environmental activities, especiallythose not readily visible in yearly TRItotals. The Public Environmental ReportingInitiative (PERI) recognizes the importanceof TRI data as an indicator of a company’senvironmental status, and although thePERI guidelines4 do not require companiesto provide TRI data in their reports, PERIencourages them to do so. Another envi-ronmental reporting initiative, the Coali-tion for Environmentally ResponsibleEconomies (CERES)5 asks explicitly forTRI data and information on reductionstrategies.

Companies and industries find uses forTRI other than public reporting. It providesa convenient measure for releases andtransfers that, when combined with otheravailable information such as p r od u c t i o nlevels and number of employees, helps toset an industry standard. In turn, thisallows companies to compare theirenvironmental performance and formulatecompetitive initiatives. A recent surveyby the Minnesota Center for SurveyResearch asked facilities which informationsources they used to analyze processesand operations.6 Eighty-three percent

reported using TRI data for these purposes,more than any other measure such as envi-ronmental audits or materials accountingrecords. Companies often cite emissionsreduction projects as money savers.7 TRIprovides a way for facilities to identifyprocess and operations generating themost emissions.

4.2.2 Government Use of TRIData

Although US facilities had to submitvarious release and hazardous waste datato federal and state agencies before theadvent of TRI, this data is unique in thatfacilities submit a single form for eachchemical. Having all the information inone database is an important step in settingnational priorities, and TRI has resultedin a number of governmental initiatives.

The 33/50 Program is a voluntary EPAinitiative to reduce releases and transfersof 17 priority pollutants 33 percent by1992 and 50 percent by 1995, based on1988 TRI data. Companies are allowedto formulate any reduction goal for anychemical; in fact, setting a goal is not arequirement for participation. The EPAselected the 17 chemicals based on toxicityand released amounts, so TRI was usedin formulating the program as well asproviding measurement. To date, the 33/50Program has over 1,200 participating com-panies pledging some 350 million poundsin reductions of releases and transfers, andindustry is expected to achieve its 50 per-cent reduction in 1994, one year aheadof schedule.

The EPA regional offices and stategovernments use TRI as a source of datafor reduction and technical assistanceinitiatives. The Merit Program in southernCalifornia is an EPA initiative to reduceTRI emissions. EPA officials work withfacilities to identify areas for reductionand to develop reduction goals. Two

additional programs, the Great LakesInitiative and the Chesapeake Bay Program,both have TRI reduction componentsthat allow measurement of progress. TheEPA also considers facilities’ TRI data inassessing penalties for compliance viola-tions: several companies have reporteddecreased fines based on demonstratedTRI reductions.8

States use TRI data in a number of ways,from setting environmental filing fees tousing TRI as the basis for collecting addi-tional data on materials accounting anduse. New Jersey and Massachusetts haveboth expanded on TRI reporting andrequire facilities to supply additionaldata. In addition, both states have insti-tuted pollution-prevention planningrequirements that seek reductions inTRI production-related waste. Minnesotahas its own 33/50-type reduction programcalled “Minnesota-50”, and requiresfacilities to develop pollution preventionplans using TRI data as a baseline.

Local governments are finding TRI to bean indicator of environmental performancethat can be used in a number of decision-making processes. Since most PubliclyOwned Treatment Works (POTWs) arerun by municipalities, local governmentsfind the TRI POTW data useful as asupplement to their own operating data.In addition, many governments are linkingcompanies’ proposed expansion plans andchanges in operation to demonstratedTRI reductions by basing approval ofbuilding permits, zoning changes, andinvestment of funds in infrastructureimprovement on performance as measuredby TRI.

4.2.3 Academic, NGO andPublic Use of TRI data

TRI has probably been of most benefit tocommunities and individuals who use thedata to learn more about sources of chem-

icals in their environment. Initially,government and industry questioned ifanyone was really interested in the amountof detail required by TRI. Every year,however, major American newspapersprint articles after the EPA releases thenew TRI data, creating a flurry of interestin facilities that top the list. However,beyond these national glimpses, mostinterest in TRI is at the local level, andthe EPA no longer doubts the usefulnessof TRI data to communities and indivi-duals. In a recent presentation to represen-tatives of other countries considering PRT Rreporting, Susan Hazen of EPA affirmedthat, “an informed public protects theenvironment”.

From questions about odours comingfrom the factory at the end of the streetto concerns about environmental justice,citizens and NGOs have many uses forTRI data. While the stories that makenews are usually accounts of confrontation,TRI’s most important use is in providingthe basis for informed discussion betweeninterested parties seeking common solutions.

In 1994, for example, a neighborhood groupin Columbus, Ohio, voiced its concernabout lead use at a local facility manu-facturing television picture tubes. Facilityrepresentatives were initially reluctantto meet with the neighborhood group,and issued statements that the facilitywas in compliance with all regulations.The neighborhood group contactedOhio Citizens’ Action, which determinedthat the facility’s TRI data showed noabnormal level of releases. This informationbecame the basis of discussion betweenthe citizens’ group and the facility. Theend result was a series of articles in thelocal newspaper describing improvementsat the plant, and an agreement to meeton a regular basis and discuss neighborhoodconcerns.9 A small specialty chemicalmanufacturer in New Jersey reports thatlocal residents monitor their TRI data

every year, and the data form a basis fordialogue between the facility and theneighborhood.

Facilities sometimes find that addressingn e i g h b o r h o od concerns leads to fin a n c i a lsavings. Residents in Flat Rock, Michigan,contacted the Ecology Center in AnnArbor to ask about odours from a localautomobile manufacturing plant. Theplant’s TRI data indicated an eight-foldincrease in toluene air emissions over atwo-year period. The residents’ complaintswere an important factor in the facility’sdecision to install a solvent recovery sys-tem that will save money as well as addressthe neighborhood odour problem.10

4.4 CONCLUSIONS

The uses of PRTR data are broad andcontinue to evolve significantly. Today,the TRI data are being used in ways neverimagined by its initial proponents. Fromlifecycle analysis to community-basedrisk assessment, academic and socialstudies, or linkage with a host of otherdatabases on population, demographics,employment, and financial earnings, TRIhas become the pre-eminent environ-mental database in the United States. TheCanadian NPRI and proposed MexicanRETC are likely to be of similar value asthey become known to potential users.And, as more countries develop PRTRs,uses for the data will increase. To theextent that the data are able to providecomparable information, PRTRs fromdifferent countries can provide insightsinto regional and global environmentalissues. Just as the uses of TRI data haveevolved over the past eight years, so toowill uses for international data.

This report has described the NPRI,TRI, and proposed RETC systems andhas suggested ways to fit the pieces ofinformation from the individual systemstogether into a picture with pan-NorthAmerican significance. In fact, the NPRI,TRI and proposed R E T C share many keyPRTR characteristics that increase theability to compare data.

H o w e v e r, the NPRI, TRI and the proposedRETC also have differences which mustbe taken into account when comparingdata. The decisions made in designingthe R E T C will determine the final degreeof compatibility between the forthcomingMexican PRTR and the other two NorthAmerican systems.

The PRTR systems in all three countriesare evolving. There are proposed legislativechanges to the NPRI in Canada, a majorexpansion to the TRI list of chemicals,along with other proposals to expand thenumber of reporting industries and thecontent of such reports in the US, andthe completion of a case study in Mexico.

The eight years of TRI data have beenused in countless ways by a wide array ofusers in the public, academia, media,industry and government, from trackingenvironmental performance to estimatingrisks, setting priorities, and taxing pollution.Each year sees new uses. Data from themore recently enacted NPRI are startingto gain a similarly broad application.

Later this year, the CEC will release thesecond report in this series, an analysisof NPRI and TRI data and an update onthe Mexican case study. This analysiswill be an important step towards increasedunderstanding of North America dataon the releases and transfers of toxicchemicals. It also promotes a discussionof industrial efforts to reduce wastegeneration, as well as releases andtransfers of pollutants, and a tool totrack environmental progress. It will alsobe an occasion for CEC to underscoreimportant PRTR innovations in allthree North American countries.

Chapter 5.0: Summary

39Summary

The North American PRTRs are intendedfor active and regular public dissemination.They will all report:

• on individual chemicals;• on individual facilities;• on releases and transfers;• on an annual basis; as well as• using computerized data management;

a n d• allowing for limited trade secrecy.

The North American PRTRs will have:

• different chemical lists with only aportion of the chemicals overlapping;

• different reporting thresholds;• different treatment of small releases

and transfers;• different types of facilities required to

re p o rt, with the majority of the facilitiesoverlapping; and

• choice of diff e rent industrial classific a t i o nsystems.
