Introductory note

This introductory note does not form a part of the notice

Under the Environmental Permitting (England & Wales) Regulations 2016 (schedule 5, part 1, paragraph 19) a variation may comprise a consolidated permit reflecting the variations and a notice specifying the variations included in that consolidated permit.

Schedule 1 of the notice specifies the conditions that have been varied and schedule 2 comprises a consolidated permit which reflects the variations being made. Only the variations specified in schedule 1 are subject to a right of appeal.

This variation makes the following changes to the permit:

Addition of EWC waste code 20 03 01 mixed municipal waste to the wastes allowed to be received at the Installation.

The addition of an approved Odour Management Plan (OMP).

Updating the site’s operating techniques to bring in line with site practices, specifically:

Remove the direct discharge of digestate to the feed hopper.

Reflect that Air Pollution Control Residues (APCR) is now sent off-site for recovery.

Brief description of the process

This permit controls the operation of a waste incineration plant. The relevant listed activity is 5.1 A(1)(b). The permit implements the requirements of the EU Directives on Industrial Emissions and Waste.

The main features of the site are as follows:

Furnace technology	Moving Grate
Number of lines	4
Principal waste type	RDF
Stack height	105 m
Permitted plant capacity	1,100,000 tonnes per year
Electrical generation capacity	74 MWe
Heat export capacity	53 MWth

The Energy from Waste (EfW) facility is located to the north of the Runcorn site in an area known as Weston Point. The site includes rail sidings along its eastern boundary running parallel to Picow Farm Road. This provides the site with a rail link to the north bound line at Runcorn Railway Station. The Mersey Estuary at its nearest point is located approximately 200 metres to the west of the site, beyond Weston Docks. The estuary is a Special Protection Area (SPA), designated for its nature conservation importance for feeding and roosting ducks and waders and is also a Ramsar site and Site of Special Scientific Interest (SSSI).

The EfW facility has a total capacity of approximately 360 MW (thermal input) and generates approximately 74 MW of electrical power and 64 tonnes (53 MW) of steam per hour. This provides approximately 20% of the energy requirements at the adjacent Runcorn Halochemicals installation and replaces energy that is currently derived from natural gas.

Waste material burned at the facility is primarily refuse derived fuel (RDF) and digestate produced from the Mechanical and Biological Treatment (MBT) of Municipal Solid Waste (MSW) but it also includes some appropriately treated commercial and industrial (C&I) waste and biomass. All waste material for processing received at the facility is non-hazardous. Mixed municipal waste has been added to the wastes allowed to be accepted at the facility under variation EPR/XP3005LB/V003.

The facility consists of four incinerator lines. In total, accounting for expected losses (primarily in the form of moisture, lost from the waste whilst it is stored in the bunker prior to incineration), the four lines incinerate up to 1,040,000 tonnes per year of waste with a design average net calorific value (NCV) of approximately 11 MJ/kg.

Waste material arrives either by rail or by road and is weighed before proceeding into the tipping hall where it is tipped into the RDF bunker of sufficient capacity to hold several days waste inputs.

Moving grate technology is used for burning the waste material. The furnace design ensures that a temperature of at least 850°C for a period of at least two seconds is achieved in the combustion chamber. To ensure that the temperature does not fall below 850°C, auxiliary burners firing natural gas are automatically triggered by online process monitoring equipment.

Selective Non-Catalytic Reduction (SNCR), involving the injection of ammonia solution, is used for the abatement of nitrogen oxides generated within the furnace.

Hot gases from the furnace pass into a boiler. Steam raised in the boiler is passed to turbines to generate electricity or is exported as steam; both energy streams are used within the Runcorn site processes. The ability to export electricity into the National Grid is also included within the design.

Combustion gases are cleaned before they are released to atmosphere. There are two abatement stages in series. Each stage consists of a reactor where dry lime (to neutralise acid gas components) and activated carbon (to absorb heavy metals, dioxins and furans) are injected and a bag filter unit to remove fine particulates. The residues of the bag filters and the reactor are collected and directed to a residues silo.

Cleaned flue gases exiting the abatement system of each of the incinerator lines are discharged through a four flue, 105 metre tall stack.

A single process water discharge from the facility, primarily comprising cooling water purge from the cooling towers and excess rainwater, is released directly into the disused Runcorn & Weston Canal.

All plant areas are surfaced to the appropriate standards for the activities within those areas. All liquid tanks and drums, whose emissions to water or land could cause pollution, are contained in adequate bunding constructed in line with industry best practice standards and sized to contain 110% of the tank contents. Materials used for surfacing of process areas and bunds are resistant to the stored materials.

There are no direct discharges to groundwater from the facility.

Any potential odours from storage of the waste materials are extracted from above the storage bunker and used as combustion air within the furnace, thereby destroying any potentially odorous compounds.

An odour management plan has been added to the permit under variation EPR/XP3005LB/V003.

The main solid residues produced by the facility are bottom ash and air pollution control (APC) residues. Bottom ash is processed by contractor and may be sent for incorporation within aggregates or building blocks. APC residues are hazardous and are sent off site for recovery..

The operator shall take appropriate measures to ensure that:

the waste hierarchy referred to in Article 4 of the Waste Framework Directive is applied to the generation of waste by the activities; and

any waste generated by the activities is treated in accordance with the waste hierarchy referred to in Article 4 of the Waste Framework Directive; and

where disposal is necessary, this is undertaken in a manner which minimises its impact on the environment.

The operator shall review and record at least every four years whether changes to those measures should be made and take any further appropriate measures identified by a review.

Operations

Permitted activities

The operator is only authorised to carry out the activities specified in schedule 1 table S1.1 (the “activities”).

Waste authorised by this permit shall be clearly distinguished from any other waste on the site.

The site

The activities shall not extend beyond the site, being the land shown edged in green on the site plan at schedule 7 to this permit.

Operating techniques

The activities shall, subject to the conditions of this permit, be operated using the techniques and in the manner described in the documentation specified in schedule 1, table S1.2, unless otherwise agreed in writing by the Environment Agency.

If notified by the Environment Agency that the activities are giving rise to pollution, the operator shall submit to the Environment Agency for approval within the period specified, a revision of any plan specified in schedule 1, table S1.2 or otherwise required under this permit which identifies and minimises the risks of pollution relevant to that plan , and shall implement the approved revised plan in place of the original from the date of approval, unless otherwise agreed in writing by the Environment Agency.

Any raw materials or fuels listed in schedule 2 table S2.1 shall conform to the specifications set out in that table.

Waste shall only be accepted if:

it is of a type and quantity listed in schedule 2 table(s) S2.2; and

it conforms to the description in the documentation supplied by the producer or holder.

Waste paper, metal, plastic or glass that has been separately collected for the purpose of preparing for re-use or recycling shall not be accepted. Waste from the treatment of these separately collected wastes shall only be accepted if incineration delivers the best environmental outcome in accordance with regulation 12 of the Waste (England and Wales) Regulations 2011.

Separately collected fractions other than those listed in condition 2.3.5 shall not be accepted unless they are unsuitable for recovery by recycling.

The operator shall ensure that where waste produced by the activities is sent to a relevant waste operation, that operation is provided with the following information, prior to the receipt of the waste:

the nature of the process producing the waste;

the composition of the waste;

the handling requirements of the waste;

the hazardous property associated with the waste, if applicable; and

the waste code of the waste.

The operator shall ensure that where waste produced by the activities is sent to a landfill site, it meets the waste acceptance criteria for that landfill.

Waste shall not be charged if:

the combustion chamber temperature is below 850 oC,

any continuous emission limit value in schedule 3 table S3.1(a) is exceeded during abnormal operation; or

any continuous emission limit value in schedule 3 table S3.1 is exceeded, other than during abnormal operation; or

continuous emission monitors to demonstrate compliance with any continuous emission limit value in schedule 3 table S3.1 are unavailable other than during abnormal operation; or

there is a stoppage, disturbance or failure of the activated carbon abatement system, other than during abnormal operation.

continuous emission monitors to demonstrate compliance with the emission limit values for particulates, TOC or CO in schedule 3 are unavailable unless alternative techniques, as agreed in writing with the Environment Agency, are used to demonstrate compliance with those emission limit values.

The operator shall record the beginning and end of each period of “abnormal operation”.

During a period of “abnormal operation”, the operator shall restore normal operation of the failed equipment or replace the failed equipment as soon as possible.

The operator shall interpret the start of the period of “abnormal operation” as the earliest of the following:

a technically unavoidable stoppage, disturbance, or failure of continuous emission monitors.

a technically unavoidable stoppage, disturbance, or failure of the activated carbon abatement system

any other technically unavoidable stoppage, disturbance, or failure of the plant which is causing or could lead to an exceedance of an emission limit value in table S3.1.

The operator shall interpret the end of the period of “abnormal operation” as the earliest of the following:

when the failed equipment is repaired and brought back into normal operation;

when the operator initiates a shut down of the waste combustion activity, as described in the application or as agreed in writing with the Environment Agency;

The failed equipment has not been repaired and brought back into normal operation and a single period of abnormal operation reaches a duration of 4 hours after the start of abnormal operation on an incineration line

Abnormal operation occurs on an incineration line and the cumulative duration of abnormal operation periods over 1 calendar year has reached 60 hours on that incineration line;

The operator shall have at least one auxiliary burner in each line which shall be operated at start up, shut down and as required during operation to ensure that the operating temperature specified in condition 2.3.9 is maintained as long as incompletely burned waste is present in the combustion chamber. Unless the temperature specified in condition 2.3.9 is maintained in the combustion chamber, such burner(s) shall be fed only with fuels which result in emissions no higher than those arising from the use of gas oil, liquefied gas or natural gas.

Bottom ash and APC residues shall not be mixed.

Improvement programme

The operator shall complete the improvements specified in schedule 1 table S1.3 by the date specified in that table unless otherwise agreed in writing by the Environment Agency.

Except in the case of an improvement which consists only of a submission to the Environment Agency, the operator shall notify the Environment Agency within 14 days of completion of each improvement.

Emissions and monitoring

Emissions to water, air or land

There shall be no point source emissions to water, air or land except from the sources and emission points listed in schedule 3 tables S3.1 and S3.2.

The limits given in schedule 3, subject to condition 3.2.1, shall not be exceeded.

Wastes produced at the site shall, as a minimum, be sampled and analysed in accordance with schedule 3 table S 3.4. Additional samples shall be taken and tested and appropriate action taken, whenever:

disposal or recovery routes change; or

it is suspected that the nature or composition of the waste has changed such that the route currently selected may no longer be appropriate.

Emissions limits and monitoring for emission to air for incineration plant

The limits for emissions to air apply as follows:

The limits in table S3.1 shall not be exceeded except during periods of abnormal operation.

The limits in table S3.1 (a) shall not be exceeded during abnormal operation.

Where Continuous Emission Monitors are installed to comply with the monitoring requirements in schedule 3 table S3.1 and S3.1(a); the Continuous Emission Monitors shall be used such that;

the values of the 95% confidence intervals of a single measured result at the daily emission limit value shall not exceed the following percentages of the emission limit values:

Carbon monoxide	10%

Sulphur dioxide	20%

Oxides of nitrogen (NO & NO2 expressed as NO2)	20%

Particulate matter	30%

Total organic carbon (TOC)	30%

Hydrogen chloride	40%

Ammonia	40%

valid half-hourly average values or 10-minute averages shall be determined within the effective operating time (excluding the start-up and shut-down periods) from the measured values after having subtracted the value of the confidence intervals in condition 3.2.2 (a).

where it is necessary to calibrate or maintain the monitor and this means that data are not available for a complete half-hour or 10 minute period, the half-hourly average or 10-minute average shall in any case be considered valid if measurements are available for a minimum of 20 minutes or 7 minutes during the half-hour or 10-minute period respectively. The number of half-hourly or 10-minute averages so validated shall not exceed 5 or 15 respectively per day;

daily average values shall be calculated as follows:

the average of valid half hourly averages or 10 minute averages over a calendar day excluding half hourly averages or 10 minute averages during periods of abnormal operation. The daily average value shall be considered valid if no more than five half-hourly average or fifteen 10-minute average values in any day have been determined not to be valid;

no more than ten daily average values per year shall be determined not to be valid.

Emissions of substances not controlled by emission limits

Emissions of substances not controlled by emission limits (excluding odour) shall not cause pollution. The operator shall not be taken to have breached this condition if appropriate measures, including, but not limited to, those specified in any approved emissions management plan, have been taken to prevent or where that is not practicable, to minimise, those emissions.

The operator shall:

if notified by the Environment Agency that the activities are giving rise to pollution, submit to the Environment Agency for approval within the period specified, an emissions management plan which identifies and minimises the risks of pollution from emissions of substances not controlled by emission limits;

implement the approved emissions management plan, from the date of approval, unless otherwise agreed in writing by the Environment Agency.

All liquids in containers, whose emission to water or land could cause pollution, shall be provided with secondary containment, unless the operator has used other appropriate measures to prevent or where that is not practicable, to minimise, leakage and spillage from the primary container.

Periodic monitoring shall be carried out at least once every 5 years for groundwater and 10 years for soil, unless such monitoring is based on a systematic appraisal of the risk of contamination.

Odour

Emissions from the activities shall be free from odour at levels likely to cause pollution outside the site, as perceived by an authorised officer of the Environment Agency, unless the operator has used appropriate measures, including, but not limited to, those specified in any approved odour management plan, to prevent or where that is not practicable to minimise the odour.

Noise and vibration

Emissions from the activities shall be free from noise and vibration at levels likely to cause pollution outside the site, as perceived by an authorised officer of the Environment Agency, unless the operator has used appropriate measures, including, but not limited to, those specified in any approved noise and vibration management plan to prevent or where that is not practicable to minimise the noise and vibration.

The operator shall:

if notified by the Environment Agency that the activities are giving rise to pollution outside the site due to noise and vibration, submit to the Environment Agency for approval within the period specified, a noise and vibration management plan which identifies and minimises the risks of pollution from noise and vibration;

implement the approved noise and vibration management plan, from the date of approval, unless otherwise agreed in writing by the Environment Agency.

Monitoring

The operator shall, unless otherwise agreed in writing by the Environment Agency, undertake the monitoring specified in the following tables in schedule 3 to this permit:

point source emissions specified in tables S3.1, S3.1(a) and S3.2;

process monitoring specified in table S3.3;

residue quality in table S3.4.

The operator shall maintain records of all monitoring required by this permit including records of the taking and analysis of samples, instrument measurements (periodic and continual), calibrations, examinations, tests and surveys and any assessment or evaluation made on the basis of such data.

Monitoring equipment, techniques, personnel and organisations employed for the emissions monitoring programme and the environmental or other monitoring specified in condition 3.6.1 shall have either MCERTS certification or MCERTS accreditation (as appropriate) unless otherwise agreed in writing by the Environment Agency. Newly installed CEMs, or CEMs replacing existing CEMs, shall have MCERTS certification and unless otherwise agreed in writing by the Environment Agency have an MCERTS certified range which is not greater than 1.5 times the daily emission limit value (ELV) specified in schedule 3 table S3.1. The CEM shall also be able to measure instantaneous values over the ranges which are to be expected during all operating conditions. If it is necessary to use more than one range setting of the CEM to achieve this requirement, the CEM shall be verified for monitoring supplementary, higher ranges. Newly installed Data handling and acquisition systems (DAHS), or DAHS replacing existing DAHS, shall have MCERTS certification.

Permanent means of access shall be provided to enable sampling/monitoring to be carried out in relation to the emission points specified in schedule 3 tables S3.1, S3.1(a) and S3.2 unless otherwise agreed in writing by the Environment Agency.

Pests

The activities shall not give rise to the presence of pests which are likely to cause pollution, hazard or annoyance outside the boundary of the site. The operator shall not be taken to have breached this condition if appropriate measures, including, but not limited to, those specified in any approved pests management plan, have been taken to prevent or where that is not practicable, to minimise the presence of pests on the site.

The operator shall:

if notified by the Environment Agency, submit to the Environment Agency for approval within the period specified, a pests management plan which identifies and minimises risks of pollution from pests;

implement the pests management plan, from the date of approval, unless otherwise agreed in writing by the Environment Agency.

“PAH” means Poly-cyclic aromatic hydrocarbon, and comprises Anthanthrene, Benzo[a]anthracene, Benzo[b]fluoranthene, Benzo[k]fluoranthene, Benzo[b]naph(2,1-d)thiophene, Benzo[c]phenanthrene, Benzo[ghi]perylene, Benzo[a]pyrene, Cholanthrene, Chrysene, Cyclopenta[c,d]pyrene, Dibenzo[ah]anthracene, Dibenzo[a,i]pyrene Fluoranthene, Indo[1,2,3-cd]pyrene, Naphthalene

“PCB” means Polychlorinated Biphenyl. Dioxin-like PCBs are the non-ortho and mono-ortho PCBs listed in the table below.

“Pests” means Birds, Vermin and Insects.

“quarter” means a calendar year quarter commencing on 1 January, 1 April, 1 July or 1 October.

“recovery” means any of the operations provided for in Annex II to Directive 2008/98/EC of the European Parliament and of the Council on waste.

“start up” is any period, where the plant has been non-operational, until waste has been fed to the plant in a sufficient quantity to initiate steady-state conditions as described in the application or as agreed in writing with the Environment Agency.

“shut down” is any period where the plant is being returned to a non-operational state as described in the application or as agreed in writing with the Environment Agency.

“TOC” means Total Organic Carbon. In respect of releases to air, this means the gaseous and vaporous organic substances, expressed as TOC. In respect of Bottom Ash, this means the total carbon content of all organic species present in the ash (excluding carbon in elemental form).

“Waste code” means the six digit code referable to a type of waste in accordance with the List of Wastes and in relation to hazardous waste, includes the asterisk

“Waste Framework Directive” or “WFD” means Waste Framework Directive 2008/98/EC of the European Parliament and of the Council on waste

Where a minimum limit is set for any emission parameter, for example pH, reference to exceeding the limit shall mean that the parameter shall not be less than that limit.

Unless otherwise stated, any references in this permit to concentrations of substances in emissions into air means:

in relation to emissions from combustion processes, the concentration in dry air at a temperature of 273K, at a pressure of 101.3 kPa and with an oxygen content of 3% dry for liquid and gaseous fuels, 6% dry for solid fuels; and/or

in relation to emissions from non-combustion sources, the concentration at a temperature of 273K and at a pressure of 101.3 kPa, with no correction for water vapour content

in relation to gases from incineration plants other than those burning waste oil, the concentration in dry air at a temperature of 273K, at a pressure of 101.3 kPa and with an oxygen content of 11% dry,

For dioxins/furans and dioxin-like PCBs the determination of the toxic equivalence concentration (I-TEQ, & WHO-TEQ for dioxins/furans, WHO-TEQ for dioxin-like PCBs) stated as a release limit and/ or reporting requirement, the mass concentrations of the following congeners have to be multiplied with their respective toxic equivalence factors before summing. When reporting on measurements of dioxins/furans and dioxin-like PCBs, the toxic equivalence concentrations should be reported as a range based on: all congeners less than the detection limit assumed to be zero as a minimum, and all congeners less than the detection limit assumed to be at the detection limit as a maximum. However the minimum value should be used when assessing compliance with the emission limit value in table S3.1.
