Annual Guide 2019 I SOURCE TESTING ASSOCIATION
Any MCP located on an IED regulated site, will fall within the scope of the IED general provisions, creating a regulatory overlap; however, it is clear that any MCPs in this category will be permitted under the IED with MCPD emission limit values also applying as a minimum requirement.
Registration or Permitting
MCPs must be either registered or permitted, as determined by each Member State, before fi rst operation for a new MCP, or at least one year prior to the required ELV compliance date for existing MCPs.
Operators must provide the following information when registering or applying for a permit:
• Rated thermal input of the MCP
• Type of MCP: diesel engine; gas turbine; dual fuel engine; other engine or other medium combustion plants
• Type and share of fuels used by fuel category: solid biomass; other solid fuels; gas oil; other liquid fuels; natural gas; other gaseous fuels
• Date of the start of the operation
• Activity sector of the MCP or the facility in which it is applied (NACE code)
• Expected number of annual operating hours and average load in use
• Signed declaration that the MCP will not be operated > 500 hours per annum (if applicable)
• Name and registered offi ce of the operator and the address where the plant is located.
The time-line for MCPD implementation is shown in the fi gure. Emission Limits Values (ELVs)
the operator can demonstrate to the Competent Authority that a longer period is justifi ed). MCPs that normally fi re low sulphur fuel may similarly be exempted from their SO2
ELVs for a
maximum of six months if there is an interruption in the supply of low sulphur fuel due to a serious shortage.
In addition to these exemptions, there are a number of other optional exemptions that a Member State may or may not adopt. For existing plants, the main provision is an exemption from ELVs for plants operating ≤ 500 hours per annum, as a rolling average over fi ve years, subject to meeting a dust ELV of 200 mg/m3
for
plants fi ring solid fuels. This may optionally be extended to 1000 hours for heating plants during exceptionally cold weather events.
There are also time limited derogations for Isolated Systems (applicable to island communities), district heating systems and gas compressor stations within national transmissions systems noting that, in some cases, less stringent ELVs are imposed.
For new plants, the main optional exemption is again available for plants operating < 500 hours per annum, as a rolling average over three years, subject to meeting a dust ELV of 100 mg/m3
for MCPs
fi ring solid fuels. There is also an optional series of derogations, specifying less onerous NOx
500 and 1500 hours per annum dependent upon engine type and fuelling. This provision for new engines is surprising given that there is no equivalent provision for existing engines.
The most important ELV provisions are described below by technology type.
Gas turbine Emission Limit Values are given in Table 1 for new plants in and Table 2 for existing plants in mg/m3
dry, 273K, 101.3 kPa. NOx ELVs are only applicable over 70% load and there are higher SO2
at 15% O2
ELVs for small MCPs. Table 1. Gas Turbine ELVs for NEW plants (mg/m3

Certain ELV compliance exemptions apply to all classes of MCP. Those located in the Canary Islands, French Overseas Departments, the Azores and Madeira are indefi nitely and fully exempted from ELV compliance. Gas fi red MCPs that suffer a fuel supply interruption may be exempted when fi ring alternative fuels that would require secondary abatement to comply with the applicable ELVs (for ten days interruption unless

Combustion plants - other than gas turbines and engines - have Emission Limit Values as shown in Table 3 for new planst and Table 4 for existing plants in mg/m3 at 3% O2 gas and liquid fuel fi ring and at 6% O2 for solid fuels. There are various SO2
