Provision of National Ecosystems Monitoring Support 2022 to 2026 – Monitoring Air Pollution Impacts across Sensitive Ecosystems

The revised National Emissions Ceiling (NEC) Directive (2016/2284) requires that Member States ensure the monitoring of negative impacts of air pollution upon ecosystems based on a network of sites that is representative of their freshwater, natural and semi-natural habitats and forest ecosystem types, taking a cost-effective and risk-based approach.

The EPA is now advancing with implementation of the NEMN in Ireland, based on guidance and recommendations included in the NEMN Design Report, plus the slight amendments to the sites as submitted to the EEA/Eionet under the Article 9 / Article 10(4) submission.

The EPA Chemicals and Ecosystems Monitoring Team requires specialised technical support and input, to support implementation activities for the period 2022-2024.


The revised National Emissions Ceiling (NEC) Directive (2016/2284) requires that Member States ensure the monitoring of negative impacts of air pollution upon ecosystems based on a network of sites that is representative of their freshwater, natural and semi-natural habitats and forest ecosystem types, taking a cost-effective and risk-based approach.

In 2020 the EPA awarded a framework agreement for technical support and input from a suitably qualified third party to support the review, establishment and operation of the National Ecosystems Monitoring Network (NEMN) over the period from 2020 to 2022. Under this contract, a report entitled ‘National Ecosystem Monitoring Network (NEMN)-Design: Monitoring Air Pollution Impacts across Sensitive Ecosystems[1] (“NEMN Design Report”)’ was developed which proposes methods for air quality monitoring, ecosystem parameters for assessment, as well as sites for inclusion in the NEMN to provide representative coverage across sensitive habitat types and major pollution gradients. This report was the basis of the submission under Article 9 of the NEC Directive that was submitted to the EEA/Eionet during 2022 in accordance with Article 10 (4) of the Directive.

The EPA is now advancing with implementation of the NEMN in Ireland, based on guidance and recommendations included in the NEMN Design Report, plus the slight amendments to the sites as submitted to the EEA/Eionet under the Article 9 / Article 10(4) submission.  The EPA Chemicals and Ecosystems Monitoring Team requires specialised technical support and input, to support implementation activities for the period 2022-2024. 


Waste Water Discharge – Application Form

This is the EPA Form used for the purpose of making an application for a Waste Water Discharge Authorisation under the European Union (Waste Water Discharge) Regulations 2007 to 2020, or for the review of an existing Waste Water Discharge authorisation

It’s useful as it outlines what data the EPA collect on waste water discharges


is it on the EPA Waste Water Priority List?

is it on the EU infringement list?

where is the primary discharge point?

what is the current plant capacity, and the remaining capacity?

is the plant overloaded?

EPA Tender: River Flow Estimation Services

Detailed Specification of Requirements

The tenderer is required to provide a service meeting the following technical and service level specifications;

•          Provide accurate river flow statistics estimates for Ireland, using a proprietary, proven modelling package and using the most appropriate catchment descriptors. The model should be capable of producing natural and artificially influenced annual and monthly flow statistics, flow duration curves and modelled time series (hydrographs) for all river types and catchment scales. The appropriateness of proposed catchment descriptors should be supported by published evidence where necessary. The existing EPA HydroTool methodology may be used for the production of flow duration curve estimates and statistics. Modelled hydrograph estimates for ungauged cachments should be based on a regionalised daily rainfall-runoff type model.

•          The service should be provided in a cloud-based interface with ESRI ArcGIS file types. The service should have a dedicated spatial database for storage of catchment descriptor information, point influence data (impoundments, abstractions and discharges), river flow gauging data and spot gauging data. 

•          The service must provide estimates of both natural flows and of flows impacted by impoundments, abstractions (surface and groundwater), and discharges (flow duration curve).

•          The service must provide estimates that incorporate observed flow data to refine modelled estimates using defendable estimation techniques.

•          Provide generated catchment watershed boundaries for selected river stretches or lake outflow points on an established river line network derived from a DTM model or attributed river catchment area grid. A hydrologically corrected DTM (20m resolution) will be supplied by the EPA, however, this DTM may require editing in conjunction with existing EPA rivers, lakes and catchment boundary GIS data sets to facilitate incorporation into the model. Sufficient allowance for such potential editing requirements should also be included for in the tender if required.

•          Provide estimates of both natural and influenced annual flow duration curves and modelled daily hydrographs for un-gauged catchments.

•          Provide estimates of both natural and influenced monthly and seasonal flow duration curves for un-gauged catchments.

•          Provide estimates of both natural and influenced defined flow statistics, including:

  • mean monthly flows
  • monthly flow duration statistics
  • annual flow duration statistics
  • defined seasonal flow duration statistics

•          Provide estimates of both monthly mean flows and mean monthly run-off volumes.

•          Provide adjusted derived flow statistics to account for presence of lakes within catchments

•          Provide weighted flow estimates using long term observed flow records from permanent river flow gauging stations.

•          Provide flow duration curves and daily modelled hydrographs for un-gauged catchments using spot flow gauging data and attributed flow duration from gauged catchments of similar character.

•          Provide derived catchment statistics that will assist in understanding surface water/groundwater connectivity, for example BFIHOST, BFI.

•          The service must provide the ability to view, manage and update all artificial influence data, gauged flow data and spot flow gauging data through a graphical user interface.

•          Provide storable and printable reports of summary catchment descriptor information and summary catchment influence data for each flow estimate generated in an appropriate format.  These formats should be of generic type and compatible to upload to standard software packages such as Microsoft Excel, Access and Word (e.g. CSV, dbf, text, etc.).

•          Produce summary reports of calculated errors for any given flow estimate performed.

•          Provide the facility of incorporating actual field flow measurements (spot gauging data) into the model to assist in improving modelled estimates and to be able to update the model on new abstraction and discharge data to ensure artificially influenced statistics are current and accurate.

•          Provide estimates of abstraction pressures based on flow duration curve percentages and waterbody sensitivity classes provided by the EPA in spreadsheet and/or GIS formats.

•          Provide a vector GIS layer based on the EPA Rivers layer which is appended with the naturalised flow statistics for the downstream point of each node to node river reach in the shapefile. This file will be made publicly available by the EPA on their geoportal for view and download. Ideally a Creative Commons Attribution 4.0 open licence would apply.

•          Provide and maintain a hosted service available internally to the staff in the Hydrometric and Groundwater Section of the EPA capable of providing naturalised flow duration curve statistics, modelled hydrographs, as well as scenario modelling, eflow analysis  and water resources management functionality. It is envisaged that up to 5 individual user licences will be required for this service.

•          Hosted Service

EPA’s Water Abstraction Volume Estimator

Registration of a water abstraction is required when then maximum daily abstraction is expected to exceed 25 m3/d and is not required for any abstraction below this amount. This document can be used to estimate abstraction volumes for various sectors where the abstraction volume is not directly monitored.

The estimates in this document have been prepared in consultation with the various sectors who abstract water and following review of relevant studies on abstraction volume

The following sectors are known to have abstractions greater than 25 m3/d:
1. Agriculture (Livestock);
2. Agriculture (Irrigation);
3. Agriculture (Horticulture);
4. Drinking water supply (Public Supplies);
5. Drinking water supply (Group Water Schemes and large private supplies);
6. Aquaculture;
7. Golf course;
8. Hydropower;
9. Industrial (IPC/IED/Waste licensed);
10. Industrial of commercial (unlicensed));
11. Mining and quarrying;
12. Peat extraction;
13. Horse Racing Courses.

EPA Spatial ETL (Extract, Transform, Load) Software

The EPA is seeking to procure spatial ETL (Extract, Transform, Load) software to assist in its spatial dataset development, workflow, and modelling tasks. The EPA receives data from a number of different sources in multiple data formats. From this data the EPA generates and builds additional datasets, import the data into existing system and run analysis and modelling on the relevant datasets

At a minimum the tool will have the ability to support multiple data formats such as (but not limited to): Shapefile, Excel, CSV, Geodatabase, SQL, KML, TAB, DWG, JSON, LiDAR, ECW, PDF, GML, PostgreSQL, GPX.

Management Strategies for the Protection of High Status Water Bodies


The EPA commissioned research in this area to

  • review existing legislation relevant to the protection and management of high status sites
  • review international best practice on protecting these sites; and
  • recommend new approaches to ensuring that high status water bodies remain at high status.

The report proposes key strategies to protect & manage high status waters.
