POLLUTION LOAD COMPILATION - PLC

› Introduce PLC activities within HELCOM with attention to the importance of transboundary inputs and retention › Briefly mention HELCOM Nutrient Reduction Scheme and the importance of transboundary inputs - Bo Gustafsson, BNI Stockholm in the next presentation will have focus on that very important issue › Pollution Load Compilation is an integral part of HELCOM assessment since 1987: focusing on annual and periodical assessment of air- and waterborne inputs and selected hazardous substances entering to the Baltic Sea: collection riverine, direct and atmospheric inputs to the Baltic Sea

Aims of PLC assessments:

  • Air and waterborne nutrient inputs
  • Time-series, trend and changes
  • Main pathways and sources
  • Evaluate effects of measures taken

Assessing progress in fulfilling HELCOM nutrient reduction scheme

› HELCOM have two Recommendation (HELCOM “legal” acts)

  • bliging Contracting Parties to monitor, collect and submit

data for annual and periodic assessments: Airborne inputs: Waterborne inputs:

› Regularly assessments on waterborne inputs started with PLC1 in 1987, since PLC2-PLC5. The latest PLC assessment – PLC5.5 was published earlier this year:

› Some very few examples from the latest assessment (PLC-5.5) › – please note that in most figures we have allocated waterborne inputs to the country with the river outlet as we did not have the necessary information on transboundary inputs and on retention in surface waters of countries receiving transboundary inputs › On airborne inputs EMEP provide information on the source for deposition including inputs transboundary from countries

  • utside EU, Baltic Se and North Sea shipping etc.

› Quantifying transboundary waterborne inputs and the proportion of these reaching the Baltic Sea (retention remove some of the transboundary inputs) is a major challenge

HELCOM REDUCTION SCHEME

› Baltic Sea Action Plan 2007 decided on maximum allowable inputs (MAI) to the Baltic Sea that in the long run will would allow for fulfilment of eutrophication targets and the needed reductions in inputs compared with a reference period (1997-203) › The HELCOM ministers in 2013adopted a revised nutrient reduction scheme with revised MAI and new country allocated reduction targets (CART) › CARTS are based on the net input from the countries taking into account transboundary inputs between contracting parties and from countries (and sources) outside HELCOM. It takes also into account retention in receiving countries surface waters › Bo will tell more about MAI and CART but now follows a couple of extracts from the Ministerial Declaration in 2013

› CART assessment follow-up: draft finalized and forwarded (today) for HOD’s adoption in June 2015 › Will be accessible on HELCOM’s web-site together with the data › CART follows the national inputs (net inputs) by taking into account estimated transboundary inputs and estimated retention in catchment receiving these inputs

› The CART follow-up assessment requires good information on transboundary inputs and on inland surface water retention e.g. for inputs to GUR and for some Countries › HELCOM HOD’s decided to cooperate more closely with transboundary river basin commissions: › - engage them in work to reduce nutrients inputs to the Balti Sea to reach CART › - engage them to improve data on transboundary pollution inputs and on retention within surface waters › - agreed to arrange this workshop on updating knowledge on transboundary inputs and retention coefficients and invite river basin commissions to participate
