Stockholm Convention (2004)Global treaty to protect human health and the

environment from chemicals that remain intact in the environment for long periods, become widely distributed geographically, accumulate in the fatty tissue of humans and wildlife, and have harmful impacts on human health or on the environment.

Prohibit, eliminate or restrict the production and use, as well as the import and export, of the intentionally produced POPs.

Reduce or eliminate releases from unintentionally produced POPs

EU LEGISLATION• EU Member States are free to adopt legislation in the

absence of EU legislation• Where the Community has acted, EU legislation is supreme

and binding, taking precedence over both past and future Member State actions

• Member States must at least, fullfil the requirements of the EU directives

Categories of activities that require environmental permit

Energy industriesProduction and processing of metalsMineral industryChemical industryWaste management

Urban wastewater treatment plants discharging > 50 m3/day wastewater into the environment.

Production and processing of metals

Metal ore (including sulphide ore) roasting or sintering

Production of pig iron or steel (primary or secondary fusion) including continuous casting, with a capacity exceeding 2,5 tonnes per hour

 Processing of ferrous metals: operation of hot-rolling mills with a capacity exceeding 20 tonnes of crude steel per hour; operation of smitheries with hammers the energy of which exceeds 50 kilojoule per hammer,

where the calorific power used exceeds 20 MW; application of protective fused metal coats with an input exceeding 2 tonnes of crude steel

per hour.

 Operation of ferrous metal foundries with a production capacity exceeding 20 tonnes per day

Processing of non-ferrous metals: production of non-ferrous crude metals from ore, concentrates or secondary raw materials by

metallurgical, chemical or electrolytic processes; melting, including the alloyage, of non-ferrous metals, including recovered products and

operation of non- ferrous metal foundries, with a melting capacity exceeding 4 tonnes per day for lead and cadmium or 20 tonnes per day for all other metals.

Surface treatment of metals or plastic materials using an electrolytic or chemical process where the volume of the treatment vats exceeds 30 m3

European Pollutant Release and Transfer Register (E-PRTR) (166/2006)

Releases of listed pollutants that must be reported by the operators of the facilities carrying out the specific activities, such as: Production and processing of metals Urban wastewater treatment plants of > 100.000 p.e.

Urban wastewater directive (91/271/EEC and 98/15/EC)

The Directive require Member States to establish systems of prior regulation or authorisation for discharges of industrial wastewater into urban sewage collecting systems to ensure:

Treatment plant operation and sludge treatment will not be impeded;

No adverse effect on the environment (including receiving waters) will occur; and

The safe disposal of sewage sludge.

Annex I lists general requirements for industrial wastewater discharged into urban collecting systems.

Niina Vieno 14

General requirements Industrial waste water entering collecting systems and urban

waste water treatment plants shall be subject to such pre-treatment as is required in order to : protect the health of staff working in collecting systems and

treatment plants, ensure that collecting systems, waste water treatment plants

and associated equipment are not damaged, ensure that the operation of the waste water treatment plant and

the treatment of sludge are not impeded, ensure that discharges from the treatment plants do not

adversely affect the environment, or prevent receiving water from complying with other Community Directives,

ensure that sludge can be disposed of safety in an environmentally acceptable manner

Niina Vieno 15

Priority substances in the field of water policy (2013/39/EC)

As a matter of priority, causes of pollution should be identified and emissions of pollutants should be dealt with at source, in the most economically and environmentally effective manner.

INDUSTRY MUNICIPAL WASTE WATERTREATMENT PLANT

AGREEMENT

MunicipalityRegional State Administrative Agencies

Centre for Economic Development, Transport and the Environment

Content of the agreement Contains terms in regard to:

Wastewater quantity and quality (e.g. pH, BOD, nutrients, hazardous substances) NOTE that the wastewater treatment plant can decide on the limit

values for hazardous substances How the wastewater is discharged to the public sewer Pre-treatment of the industrial wastewater Obligations regarding communication Monitoring of the wastewater quantity and quality Tariffs Contractual terms (changes, terminations, liability of damages,

sanctions)

Niina Vieno 22

Wastewater tariffs For industrial wastewaters, tariffs are normally defined by

multiplying the residential tariff by factor that is > 1. This factor takes into account additional costs caused to

the municipal wastewater treatment plant due to maintenance of sewers and the treatment plant, and hindrances in the treatment process caused by the

different quality of the industrial wastewater compared to the municipal wastewater

The quantity and quality of the industrial wastewater affects on the tariff Tariff is different for every facility

SWEDEN

Swedish Water and Wastewater Association has published a guide for municipal wastewater treatment plants on receiving industrial wastewater.

Focus is on environmentally hazardous substances The industrial facility is responsible in finding out and reporting

the substances and their concentrations in the wastewater intended to be discharged to the public sewer.

Wastewater treatment plant can decide on the limit values for hazardous substances: Substances can be hazardous to the sewers (e.g. corrosion) Substances can affect the wastewater treatment, the quality of sludge

or the quality of the receiving surface water.

For example: Käppala WWTPGuides for pre-treatment

of industrial wastewatersE.g. WWTP recommends

that the wastewaters from washing hands in metal industry should be pre-treated due to increased concentrations of cadmium in wastewater.

GERMANYGerman Wastewater Regulation defines State of the

Technical Art with respect municipal wastewater as well as regarding wastewater from several industries

Minimum requirements are valid for the whole Federal Republic of Germany.Every state can decide on the specific requirements

Specific demands on wastewater of given industry segments before this sewage is mixed with other wastewaterDemands relate to harmful substances
