A combustion plant is a device in which fuels are burned to make use of the heat generated. This includes boilers, turbines, and engines. The term medium is a reference to the size of the combustion plant.
The burning of fuels in these devices gives rise to emissions of various pollutants into the air, which can include particulates (dust), nitrogen and sulphur oxides, and carbon monoxide. The purpose of the Medium Combustion Plant Regulations is to limit these emissions in order to help improve air quality to the benefit of the environment and human health.
The regulations require the registration of a medium combustion plant except where it is already included on a site holding an Industrial Emissions Licence (IEL) or an Integrated Pollution Control (IPC) licence. More details on the legislation are given below.
The European Union (Medium Combustion Plant) Regulations 2017 were signed into law in December 2017. Their purpose is to limit emissions to the atmosphere from boilers and other stationary combustion plants in the 1-50 MWTH (thermal input) range. It covers all fuel types. The Regulations transpose the Medium Combustion Plant (MCP) Directive (EU 2015/2193) which was adopted in 2015.
The regulations limit the level of emissions allowable from a Medium Combustion Plants (MCP). New MCP's are required to comply with specified Emission Limit Values (ELVs) or limits on annual hours of operation, from 20th December 2018, while operators of existing MCPs will not be required to comply with these limits until 2025 at the earliest. This will assist in limiting the impact on human health, vegetation and biodiversity which can be caused by air pollution. The regulations also specify additional requirements such as monitoring and reporting of emissions to the EPA.
Under the MCP Regulations, the EPA is required to establish and maintain a register of all MCP's that come within the scope of the Regulations, unless the MCP is located on an installation regulated by an IED or IPC licence from the EPA. MCP's which are not located on an IED or IPC licensed installation will need to be registered in accordance with the dates specified in the Regulations. The requirements of the regulations are administered by the EPA through the registration system, or through the relevant IED/IPC licences.
For operators of MCP's which are within the scope of the Regulations, the following information is important and should be read carefully. It is also advised to read the Regulations in full, to fully understand what they require of MCP operators, and of the EPA.
For existing MCP's on an existing EPA Licenced installation
For existing MCP's, no specific action is required of you. Where you propose to operate a new MCP, this will need to be authorised by the EPA prior to operation, either by means of a Condition 1 approval, Technical Amendment or licence review.
Under the European Union (Medium Combustion Plant) Regulations 2017, the operator of a medium combustion plant shall apply to the MCP register through the Agency in accordance with the following time frames:
If you are proposing to operate an MCP for the first time on or after 20th December 2018, it is especially important that you understand the different requirements that apply to ‘new’ versus ‘existing’ MCP in the Regulations, please read our FAQs.
Under the MCP Regulations, the EPA is required to establish and maintain a register of all MCP's that come within the scope of the Regulations unless the MCP is located on an installation controlled by an IED or IPC licence from the EPA. MCP's which are not located on an IED or IPC licensed installation will need to be registered, in accordance with the dates specified in the Regulations.
In order to register an MCP, operators must complete the registration process through the online EDEN portal.
NOTE: If you are a first-time user of the EDEN portal, you will need to create a user login account using the Sign Up option, and follow the instructions provided. On signing up, you should request access to the MCP module. After this, you can log in via the EDEN portal to register a new MCP. There are extensive user instructions in the Help section of the EDEN portal but if you require further assistance in relation to technical issues or queries on EDEN registration, please email us at eden@epa.ie.
On receipt of all the required information, the Agency will register the MCP and issue a Certificate of Registration to the operator. The Agency will also add the MCP to the MCP Register. The MCP Register contains key information relating to the MCP including any relevant Emission Limit Values (ELVs), and it is advisable that the operator consults the MCP regulations to ensure they are fully informed of the requirements placed on the operator of a registered MCP. The operator should also check the applicable footnotes in the Regulations which may provide further information, such as the various exemptions, derogations and variations from the prescribed ELVs. For guidance on a standardised approach to monitoring the emissions to atmosphere the operator should refer to the Agency Guidance Note on monitoring of Stack Gas Emissions from Medium Combustion Plants: Air Guidance No. 11 (AG11).
For further enquiries about the registration process, operators should email the EPA directly at mcpregistration@epa.ie.
NOTE: All applicants should ensure that their registration application has been completed correctly. Applications cannot be edited post-submission. If there is an error with the application, the applicant will be notified and will be required to withdraw their application and submit a new application

What are the EPA requirements for monitoring emissions from MCP?
Monitoring of emissions to atmosphere
The European Union (Medium Combustion Plants) Regulations 2017 require that periodic monitoring of emissions to atmosphere from medium combustion plants is carried out. Air emissions sampling and analysis is a particularly difficult aspect of environmental monitoring, and specialist equipment is required to be used. Both the sampling and analysis stages of air emissions monitoring require a high level of competency and quality control. Most MCP facilities will not carry out their own air emissions monitoring, but will instead employ a specialist contractor to carry out the monitoring and provide a report, which can be submitted to the EPA. The EPA generally supports the approach of using external specialist service providers, and would not recommend that facilities attempt to carry out their own air emissions monitoring.
In order to ensure the generation of consistent, high quality and robust monitoring data from MCP facilities, it is a mandatory requirement that all air emissions monitoring carried out is performed by an ISO 17025 accredited air monitoring contractor. Accredited air emission monitoring contractors operating in Ireland either receive their accreditation from the Irish National Accreditation Board (INAB), or else they operate under the United Kingdom Accreditation Service (UKAS).
The details of the INAB ISO 17025 accredited air emissions monitoring contractors are as follows:
The Irish-based contractors who hold UKAS ISO17025 accreditation for air emissions monitoring are as follows:
You must ensure that the air monitoring contractor you intend to use for EPA compliance monitoring holds ISO17025 accreditation. The EPA will not accept monitoring results from a monitoring contractor, who does not hold accreditation to the ISO17025 standard.
For guidance on a standardised approach to monitoring the emissions to atmosphere the operator should refer to the Agency Guidance Note on monitoring of Stack Gas Emissions from Medium Combustion Plants: Air Guidance Note 11.
What are the Medium Combustion Plant (MCP) Regulations and what is their purpose?

What is a ‘Medium Combustion Plant’?
A “combustion plant” is defined as “…any technical apparatus in which fuels are oxidised in order to use the heat thus generated” covering boilers, turbines, and engines. The regulations apply to both new and existing equipment, between 1 and 50MWth. Regulation 4(3) sets out exemptions for some specific combustion plants.
They are referred to as ‘medium’ because large combustion plants ‘LCP’ (i.e. those >50 MWth) are covered by the Industrial Emissions Directive (2010/75/EC), while small combustion plants (up to 500 kWth) are covered by the Ecodesign Directive (2009/125/EC)
What differentiates a ‘new’ from an ‘existing’ Medium Combustion Plant and why is this important?
An “existing medium combustion plant” means a medium combustion plant put into operation before 20 December 2018. A "new medium combustion plant” is any MCP that is not existing, i.e., an MCP first put into operation on or after 20 December 2018.
A new MCP must meet the relevant requirements of the Regulations from the date it is put into operation. For example, an MCP first put into operation on 20 December 2018 must be registered by this date (unless it is on an installation controlled by an IED or IPC licence), and is required to meet the relevant emission limit values from this date.
An existing MCP is not required to be registered until 2024 (5 – 50 MWth) or 2029 (1 – 5 MWth), and the relevant emission limit values will not apply until 2025 and 2030 respectively.
What do the Regulations require of MCP operators?
The main requirements are as follows:
In addition the regulations require registered operators to keep various records relating to the operation of the plant and emissions monitoring, and specify other obligations such as notifying the Agency of non-compliances. See Regulation 14 for full details.
