Dutch PRTR & eMJV for Bulgarian delegation, 17the of November 2004

Pollution Release and Transfer System (PRTR) in the

Netherlands

From monitoring via validation to presentation to the general public

For EPER, EPRTR and Aarhus

Iksan van der Putte

Information sources: RIVM (National Institute for Public Health and Environment – the Netherlands and TNO- the

Netherlands

30 years PRTR in the Netherlands

• Since 1974 registration of emissions to air, water and soil into one integrated system– the national system

• Started with the big industries (point sources)– Since 2003 electronic reporting and validation tool

• Diffuse sources integrated– Agriculture, traffic, small industries, consumers– Integrated GIS (Geographical Information System)– Based on administrative data / activity data

• Since 2002 datawarehouse available to the public– www.emissieregistratie.nl

General concept: three levels of hierarchy

Emissions

1. Compounds 2. Sources

3. Locations

• Grid 5*5 km / point sources

• Community / Water catchment area

• Provinces

>2000

>3500

>180• Env. Themes

• Profiles & blends

• Individual compounds

• Economical sector

• Individual industry / activity

Diffuse sources

Why diffuse sources– Besides EPER in the future also diffuse source to be

reported in the EPRTR (starting 2007-data in april 2009)– Increasing in importance in the Netherlands

Our implementation of Aarhus:– a Datawarehouse (since 2002)

Non-industrial

sources

Estimates from special task forces

General principles of the inventory:

Industry

Estimates based on statistical data and environmental reports

Major IndividualCompanies in industry

Emission as reported in mandatory annual environmental reports (AER)

Database

How calculated: from the national total per activity

• Some activities are related to line sources – (roads, rivers with number of cars per road)

• Point sources (industries)– Rest of (smaller industries, per number of workers per

sector per 4 digit postal code

• Surface related – Land use (agriculture), consumers (houses)

All the different locations in GIS are related to each other by their surface

Part 2: electronic reporting for the industryA tax-form for the environment?

• Since 1995 mandatory annual reporting by the industry– 250 biggest companies + 500 voluntary

• Questionnaire on paper of 100+ pages (fixed format)• Increasing amount of themes

– air, water, waste, noise, safety, soil...

• 250 (local) authorities for validation– at least 7 copies on paper

• Digitised after validation into one database – quality problems

Electronical: what’s in it for us

• For the industries– Less administrative burden: easy to use, intelligent

support, consistency check, validation, historical data for comparison ...

• For the local authorities– Easier validation and higher quality of the data

• For RIVM-EAA* and the Ministry of environment: – Higher quality of the reported data– Shorter timeframe for the reporting: faster evaluation

of environmental policies– No error-prune digitalisation afterwards

* RIVM: Netherlands Public Institute for Environment and Health

Who is who with the e-MJV (electronic Ann. Rep.)

• Ministry for Housing, Spatial Planning and Environment – owns the system and its data– Ministry of economic affairs / NOVEM added de energy

module

• Deloitte & Touche– developed the e-MJV in co-operation with RIVM-MNP

• Facilitating Organisation for the Industry– runs the helpdesk and support– responsible for digitising the paper versions

• RIVM-MNP (Environmental Assessment Agency)– implementation of the system: hosting and maintaining,

technical support

Introduction eMJV

• In 2003 we finished a pilot (2 provinces)– most problems related to the technology used for

data protection using internet– from single user to multiuser-application

• In 2004 we did a full introduction– goal set on 60 percent participation in two years– the paper route is always the alternative

Introduction eMJV

Results 2005 – 57 % participation of the industrial sites (272 out of 481)– Excluding voluntary reports: 68% – Start of integration with other inquiries related to energy– Less administrative burden for the industries in relation

to the paper format (average from 26 to 20 days per industry)

For years 2006 and further (release 3)– Integration with emission trade– Including IPPC permit registration by the local

authorities

• An intelligent form (100+ pages)– Many checks and balances

The e-MJV system

• A central database with the historical and new data

• A web-site (public and non-public part) to:– Give user support (additional helpdesk)– Reporting of data (to spreadsheets)– Reporting of status information

Technology used

• Disconnected tax-form– Visual Basic application on CD or download

• Synchronising via internet– XML, Soap toolkit, 128 bit encryption, SSL

• Oracle database– Hosting in subnet, at least three components (firewalls)

between internet and the (Oracle) database

• Authentication via login, password and pin-code– (ldap) Verisign certification (comparable with financial

transactions)

Lessons learned

• Keep it simple (the UK)– Dutch system initial costs > 2.000 k€,

Annual costs (central) 6 fte + 300 k€

• Give the history as basis• Standards do help (fixed lists of chemical

compounds, energy carriers etc. etc.) • Give profiles, but don’t make them obligatory

(emission factors, VOC-profiles)• Spend more energy in communication and less in

technology
