Detection and reduction of hazardous substance discharges in water

 

French efforts to detect and minimise the discharge and emission of hazardous substances into water sources contribute to the European goal of improving the quality of the aquatic environment, ensuring clean and safe bodies of water, and safeguarding public health. 

CTC is available to assist you in analysing your discharges and emissions.

The importance of the RSDE programme 

The prevention and mitigation of water pollution are major priorities in European water policy. 

The French national action programme to detect and minimise hazardous substance discharges in water (RSDE) began in 2002, as part of the implementation of the approach outlined in the EU's Water Framework Directive (WFD). 

In April 2004, the programme was extended to include unclassified installations, such as urban waste water treatment stations. 

 

The aims of the RSDE action programme 

The actions set out in the programme align with Europe's ambition to improve the quality of aquatic environments and safeguard public health

These targeted reduction measures form part of France’s efforts to meet the objectives set out in the Water Framework Directive, namely: 

  • to achieve good water quality in all European water bodies; 
  • to reduce or eliminate hazardous substance discharges and emissions in the aquatic environment.

What is a hazardous substance ?

Hazardous substances are compounds that are toxic, persistent and bioaccumulative. Even at very low concentrations, they can be harmful to the aquatic environment and to human health. 

Each substance is assigned a PNEC (predicted no-effect concentration) value determined by laboratory testing and based on which an environmental guideline value (EGV) is then established. When an EVG becomes regulatory, it is referred to as an environmental quality standard (EQS). 

These substances may be present in various industrial processes (in raw materials or consumables) and in the composition of numerous products intended for industrial, agricultural, or domestic use.

Regulatory framework of the RSDE action programme 

The RSDE programme is governed by several pieces of legislation, particularly Directive 2000/60/EC of 23 October 2000, which establishes a framework for Community action in the field of water. 

Specific decrees exist concerning facilities classified for environmental protection (ICPE) and waste water treatment stations. 

For facilities classified for environmental protection (ICPE) 

The Decree of 2 February 1998 relating to water sampling and consumption, as well as emissions of all kinds by environmentally-classified facilities (ICPE) subject to the authorisation procedure. 

The Decree of 24 August 2017 amending, through a series of ministerial decrees, the provisions concerning the discharge of hazardous substances into water from such facilities. 

For waste water treatment stations 

The technical note of 12 August 2016 relating to the detection of micropollutants in the raw and treated waste water of treatment stations, and their reduction. 

It repeals and replaces the circular of 29 September 2010, amended in 2015.

Facilities classified for environmental protection 

Establishments that require prefectural authorisation to operate an ICPE (classified facility for environmental protection) and that discharge into the natural environment are subject to the RSDE obligations. 

In 2004, the action programme was extended to include urban waste water treatment stations with a nominal capacity of at least 600 kg/day of BOD5. 

 

The phases of the RSDE action programme 

There are two main phases to the RSDE action programme: 

 

  • Improving knowledge of hazardous substances in water: this first phase, begun in 2002, is aimed at making an inventory of the chemical substances present in water discharges. 
  • Monitoring and reducing hazardous substances: this phase includes the implementation of initial monitoring, followed by ongoing monitoring, as well as a technical and economic study to propose measures to reduce the substances with the greatest impact.
