Outcome of Final Workshop of the HELCOM project “Improvement of the quality of data on nutrient inputs with focus on transboundary loads”

Time: 11 March 2014 Venue: Ministry for Environmental Protection and Regional Development of the Republic of Latvia

1. Opening of the Meeting The workshop was opened by the Project Manager (and Chair of the Workshop) Mr. Seppo Knuuttila, Finland.

The participants of the workshop introduced themselves. The list of participants is contained in Annex 1 of this Outcome Report. 2. Introduction The project, funded by the Finnish Ministry of the Environment, has had the main objective to support the assessment of the importance of transboundary loads in the total inputs to the Baltic Sea, in particular the transboundary nutrient loads originating from the Daugava/Western Dvina and Nemunas/Neman catchments. The project has supported the “traditional” Baltic-wide compilation and assessment of nutrient pollution load data (PLC) with additional measures to improve its quality, completeness and consistency, e.g. through building common quality control capacity in participating countries (Latvia, Lithuania and Belarus), initiating support to intercalibration exercises including testing of sampling methodology, and application of common quality assurance methods for collection of data. Preparatory work for harmonizing reporting to HELCOM with relevant EU directives will also be included. The enhanced collection and delivery of nutrient input data is a key to improved monitoring of the progress in the implementation of actions to reduce nutrient loads within EU Strategy for the Baltic Sea Region and fulfilment of the HELCOM Baltic Sea Action Plan (BSAP) regarding nutrient reduction targets. 3. Main results of the Project Mr. Seppo Knuuttila presented the main results of the two common samplings carried out in 2013 in the rivers Daugava and Nemunas on the border of the three countries (Latvia – Belarus, Lithuania – Belarus) and at the national monitoring points near to the mouth of the both rivers (+ at the mouth of the rivers Lielupe, Venta, Barta, and Gauja in Latvia). His presentation is contained in Annex 2 of this Outcome Report.

The results of samples analyzed in different laboratories were in general comparable, especially for total nitrogen. One of the most interesting findings was that concentrations of total phosphorus and nitrogen in river Daugava at the river mouth were during the 2nd sampling round half of the concentrations measured at the border between Latvia and Belarus, suggesting high retention. The existence of several large reservoirs for hydroelectric plants along the Daugava could contribute to the high retention. Conductivity was measured at all sampling sites to determine the effect of meteorological conditions (e.g. possible diluting effect of seawater) and the results were similar between the two samplings, hence the effect of intrusion of seawater could be excluded.

Outcome of Transboundary WS 1-2014

Estimates of the transboundary loads from Belarus based on the samples carried out during the project were compared with previous estimates made by BNI and data reported by Belarus and Lithuania, and these were found to be more or less comparable. In order to be able to follow how agreed and proposed investment projects for reducing nutrient loads from MWWTPs in Belarus will contribute to reaching the BSAP nutrient reduction targets for Daugava and Nemunas, more efforts should be directed to harmonizing monitoring and analysis practices and information exchange between countries as well as between countries and HELCOM.

Mr. Waldemar Jarosinski presented information about Polish monitoring of transboundary pollution as contained in Annex 3 of this Outcome Report. There is no hydrological data available for transboundary rivers from Belarus and Ukraine, meaning that although concentration data is collected, it is not possible to calculate exact transboundary loads.

Mr. Aliaksandr Pakhomau informed on activities in Belarus to assess nutrient pollution from Belarus contributing to inputs to the Baltic Sea and the use of this information to identify projects aiming at reducing pollution from point sources as contained in Annex 4 of this Outcome Report. Belarus has been involved in activities jointly with HELCOM (e.g. PURE, PRESTO and Baltic COMPASS projects) dealing with reduction of nutrient inputs from municipal waste water treatment plants and large-scale animal farms.

Ms. Anete Šturma presented information about Latvian monitoring activities in 2013 and planned for 2014 and the results of nutrient load calculations for 1991-2012 using the PLC methodology for major transboundary rivers as contained in Annex 5 of this Outcome Report. The Workshop appreciated the information that despite lack of reporting of data to the HELCOM PLC database, there has been monitoring on-going in Latvia. Latvia was encouraged to report the load calculations concerning monitored rivers and estimated inputs from unmonitored areas to the PLC database.

Mr. Svajunas Plunge presented information about monitoring of transboundary pollution between Latvia, , Belarus and Russia. The Workshop acknowledged that the Nemunas river is very complicated and that it may not be realistic to separately calculate the inputs from the different countries but that instead the share of the different countries as a proportion of the total input could be calculated more easily on an annual basis. Estimation of retention in the catchment area is likely to be the most challenging part of estimation. 4. Discussion of lessons learned and additional data needs The Workshop discussed how to deal with quality assurance and quality control (QA/QC) related to transboundary loads and the importance to ensure comparability of analysis results of laboratories in participating countries. Although several countries already have bilateral agreements to share data, there is still room for improved cooperation.

It was agreed that transboundary pollution is easier to calculate than inputs from border rivers, where it may not be possible to take measurements in the middle of the river (e.g. flow measurements). It was pointed out that countries could save resources by sharing the monitoring at border rivers, and encouraged countries to consider and discuss such cooperation bilaterally. It was also proposed that stationary measurement devices could be installed in the main rivers to save costs.

The Workshop discussed how to pool available data for calculating transboundary inputs, acknowledging that such data is important for following up national progress in fulfillment of the BSAP nutrient reduction scheme. It was noted that in many cases there are available data but that sharing and exchanging data is a challenge that needs to be addressed. It was recognized that with additional resources, coordinated monitoring at the border would be possible, but that also additional research is needed to determine retention in transboundary and border rivers.

It was noted that the challenges and additional needs with regard to data on transboundary inputs will be further discussed during the meeting of HELCOM LOAD 7/2014. 5. Future activities The Workshop was of the opinion that this project has functioned as a “screening project”. The project has provided some interesting results which especially highlight the need for further information, in particular on retention in the rivers. The Workshop suggested that more regular and coordinated monitoring of transboundary inputs should be established to provide better information as support for follow-up of the BSAP nutrient reduction scheme. It was suggested that regular data reporting from Belarus to HELCOM (e.g. for annual PLC data reporting) would be very useful, especially for the future annual follow-up of nutrient inputs and progress in achieving CART. There was a suggestion that the development of a portal for data exchange between countries would be helpful. It was noted that the new modernized PLC-water database will be able to handle transboundary loads and this will also facilitate access to transboundary input data. 6. Conclusions of the day The Workshop provided a good overview of what transboundary pollution load data exists. It was positive to learn that there actually is so much data. The challenge ahead is to consider how all the data can be accessed and made use of by the different countries and for HELCOM purposes.

Main directions of environmental policy of the Republic Belarus up to 2025 year

Important place is given to quality of groundwater and surface water by the reduction of inputs of pollutants into water bodies through measures: - reduction of domestic water consumption up to 150 liters per person per day; -reduction of water losses during intake and transportation to the consumer by 20%; - provide a centralized sewerage systems in towns with a population of over five thousand people; - termination of discharge untreated sewage waters into water bodies; - reclamation of at least 50% filtration fields in 2025 after exploitation - provision local treatment of waste water from industrial plants discharged into sewage systems; - reducing water discharges of heavy metals by 95%, persistent pollutants by 95%, nitrogen and phosphorus by 50%.

Activities in industrial sector under EU BSR Strategy • Priority 1 – To reduce nutrient inputs to the sea to acceptable levels (Poland and Finland)

Assessment of regional nutrient pollution load and identification of priority Investment projects to reduce nutrient pollution from Belarus to the Baltic Sea

Client : NORDIC ENVIRONMENT FINANCE CORPORATION (NEFCO) Beneficiary: MINISTRY OF NATURAL RESOURCES AND ENVIRONMENTAL PROTECTION OF THE REPUBLIC OF BELARUS Implementation period : Nov 2012 – Nov 2013

Project stages and objectives : 1. Baseline study (update information on nutrient pollution from the main wastewater treatment plants and large-scale animal farms as well as diffuse load from the three transboundary river basins on the territory of Belarus, the Western Bug, the Neman and the Western Dvina that discharge to the Baltic Sea. 2. Identification of priority investments to reduce cost efficiently the nutrient pollution to the Baltic Sea and to develop an action plan to implement the priority investment program for selected ten priority targets. 3. Preparation of the feasibility study for the selected investment projects.

.PURE Project on Urban Reduction of Eutrophication Project implements the HELCOM Baltic Sea Action Plan’s Eutrophication Segment and its Recommendation 28E/5 on more stringent requirements for phosphorus removal from municipal WWTPs. Project demonstrates potentials of joint implementation and joint investments in the BSR in combating the eutrophication in a cost-effective way. Brest WWTP – pilot project Project PRESTO (Project on Reduction of the Eutrophication of the Baltic Sea Today)

PRESTO combats eutrophication by improving municipal wastewater treatment with technical studies and concrete investments as well as by increasing human competence

Activities in agriculture sector under BSR Region Programme Project Comprehensive Policy Actions and Investments in the Sustainable Solutions in Agriculture in the Baltic Sea Region (Baltic COMPASS) 2010-2012 Baltic Compass is a Pan Baltic, transnational project aiming to reinforce the connection between agriculture and environment and thus lead to a more sustainable rural economy and healthier ecosystems in the Baltic Sea region

Transboundary rivers of Latvia: national monitoring strategies, programs, results gathered through the existing monitoring programs

Anete Šturma Latvian Environment, Geology and Meteorology Centre Information Analysis Department Inland Waters Division Senior specialist

Final workshop of the HELCOM project “Improvement of the quality of data on nutrient inputs with focus on transboundary loads”, 11 March 2014, Riga, Latvia

National monitoring strategies: transboundary river water quality monitoring stations

 According to Water Framework Directive (2000/60/EC) transboundary river water quality monitoring stations are clasified as surveillance monitoring stations.  According to 2000/60EC surveillance monitoring shall be carried out for each monitoring site for a period of one year during the period covered by a river basin management plan (=1 x 6 years period).  Latvia performs water quality monitoring in transboundary rivers every year (variable frequences).
