1Wim van der Maas, Netherlands Environmental Assessment Agency
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
Reporting procedures
Reporting requirements:•National•IPCC (CRF)•UNECE (LRTAP)•LCP•IPPC (EPER)

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
