Monaghan. The plan replaces the October 2025 OMP for the proposed Debris Reception Building and associated odour-control infrastructure. The revision has been prepared to align the operational odour controls with the updated Odour Impact Assessment and Air Dispersion Assessment prepared in response to Monaghan County Council Planning Ref. 25/60416. The revised assessment recognises the mixed residential, commercial and agricultural receiving environment; the presence of nearby high-sensitivity residential receptors; the presence of three nearby piggeries as separate background odour sources; and the revised OCU design basis. 1.2 Scope and Objectives The OMP provides the management framework for preventing, containing, treating, monitoring and responding to odour associated with the proposed waste-processing activities. It applies to the Debris Reception Building, covered tanks, waste transfer and temporary holding activities, associated drainage and washdown systems, and the odour-control unit (OCU).  Prevent odour generation where practicable and minimise waste-retention times.  Contain potentially odorous activities within the enclosed Debris Reception Building.  Maintain the building under negative pressure during potentially odorous operations.  Capture and treat foul air through the OCU prior to discharge via Emission Point A1.  Maintain the treated OCU outlet at 400 OUE/m³ or lower during normal operation.  Monitor routine site and boundary conditions and respond promptly to complaints or abnormal events.  Distinguish, where practicable, JC Environmental odour from other identifiable local sources, including livestock/manure odour from nearby piggeries.  Maintain records sufficient to demonstrate implementation of the OMP and corrective actions.

REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Odour Management Plan 25.574 TE Rev 1 | 16 September 2026 Page 6 2.0 Odour Management Policy and Responsibilities 2.1 Policy Statement JC Environmental will operate the proposed facility so that potentially odorous activities are effectively enclosed, captured and treated, with the objective of preventing unreasonable odour impact at nearby sensitive receptors. Odour control will be treated as an operational requirement, not as a reactive measure only.  Seek continual improvement in odour-control performance.  Prevent or minimise odour generation at source.  Use enclosure, negative pressure and effective treatment where prevention alone is not practicable.  Maintain the OCU at or below the 400 OUE/m³ normal-operating design target.  Operate in a manner that avoids unreasonable odour annoyance at sensitive receptors.  Investigate complaints promptly and implement corrective action where warranted.  Maintain good housekeeping, preventive maintenance, spill controls and drain-cleaning procedures. Table 2.1 Roles and Responsibilities Role Minimum responsibility Facility Manager / nominated responsible person Overall implementation of this OMP; ensure staffing, maintenance and corrective actions; authorise suspension/restart of odorous operations. Operators Follow waste acceptance, closed-door, extraction and housekeeping procedures; report abnormal odour, spills, fan/OCU alarms or loss of negative pressure immediately. Environmental / competent person Review monitoring records and complaints; undertake or coordinate AG5-style field assessments; review OCU performance and recommend corrective action. OCU supplier / maintenance contractor Commission and maintain the extraction/OCU system, verify airflow and treatment performance, and provide maintenance records and technical support. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Odour Management Plan 25.574 TE Rev 1 | 16 September 2026 Page 7 3.0 Site, Operations and Receiving Environment 3.1 Site and Proposed Operations JC Environmental specialises in drainage services for residential and industrial sectors. Waste associated with drainage and wastewater-related services is proposed to be received at the Mullanarry site, inspected, unloaded/decanted and screened or separated as required. The relevant waste codes identified in the planning documentation are 19 08 01 (screenings), 20 03 03 (street-cleaning residues) and 20 03 06 (waste from sewage cleaning). The proposed maximum annual waste intake is 2,000 tonnes per annum. Waste reception, unloading/decanting, debris handling and screening/separation will be undertaken within the enclosed Debris Reception Building, which has an approximate floor area of 192 m². Solid and liquid fractions will be temporarily contained pending transfer to appropriately authorised receiving facilities. Figure 1 - Revised Further Information site layout showing the Debris Reception Building and odour-control infrastructure. 3.2 Receiving Environment and Sensitive Receptors The receiving environment is mixed. Agricultural lands occur principally to the west and south-west, while established residential properties and residential estates, commercial premises and the urban edge of Carrickmacross occur around the site. The environment is therefore not characterised as predominantly agricultural. Residential properties are treated as high-sensitivity receptors. The controlled OCU discharge A1 is located at ITM E 683929, N 803346. The closest identified residential receptors are summarised below.

These are separate, pre-existing potential sources of livestock/manure odour and must be considered when interpreting ambient odour observations and complaints. The piggeries are not assigned arbitrary numerical odour emission rates within this OMP. Where source attribution is required, the investigation will consider wind direction, odour character, intensity, persistence, receptor location, the operating status of JC Environmental and the presence of other credible odour sources. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Odour Management Plan 25.574 TE Rev 1 | 16 September 2026 Page 9 4.0 Odour Control System and Performance Standard 4.1 Containment, Extraction and Treatment The odour-control strategy is based on containment, capture and treatment. Potentially odorous activities will be undertaken within the enclosed Debris Reception Building. The building will be mechanically extracted and maintained under negative pressure during odorous operations. Foul air from the process area and relevant tank/storage headspace sources will be routed to the proposed Anua Clean Air Dual-Pass Monashell OCU, or an equivalent approved dual-stage system, before vertical discharge through A1. Figure 3 - Proposed biofilter / OCU reference arrangement. 4.2 OCU Design Basis Parameter Design basis Operational requirement Nominal foul-air extraction 4,000 m³/hr (1.111 m³/s) Minimum whole-building design basis Estimated building volume Approx. 950 m³ 192 m² floor area and approx. 4.95 m average height Air-change rate Approx. 4.2 ACH 4,000 m³/hr ÷ 950 m³ Operating pressure Negative pressure During potentially odorous operations Fan arrangement Duty / standby Fault alarm and automatic changeover where practicable Controlled emission point A1 ITM E 683929, N 803346 Stack height 7.45 m Vertical treated-air discharge Outlet diameter 0.240 m Terminal outlet Calculated exit velocity Approx. 24.6 m/s At 4,000 m³/hr REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Odour Management Plan 25.574 TE Rev 1 | 16 September 2026 Page 10 4.3 Normal-Operating Performance Standard Mandatory normal-operation design target The OCU shall be selected, commissioned, operated and maintained to achieve a treated outlet odour concentration of 400 OUE/m³ or lower during normal operation. At 4,000 m³/hr, 400 OUE/m³ corresponds to an odour emission rate of approximately 444 OUE/s. The supporting conservative Gaussian screening assessment predicts approximately 1.30-1.36 OUE/m³ at the four identified residential receptors under the 400 OUE/m³ design case, below the adopted 1.5 OUE/m³ screening benchmark. The 500 OUE/m³ case is retained in the supporting assessment as a sensitivity case and is not the normal-operating design target. 4.4 Failure / Exceedance Response  If extraction or OCU failure prevents effective odour containment, waste reception, unloading, decanting, screening and other potentially odorous processing shall be suspended until effective control is restored.  Any alarm, loss of negative pressure, unusual odour breakthrough or suspected deterioration in OCU performance shall be recorded and investigated promptly.  Where commissioning or verification indicates an outlet odour concentration above 400 OUE/m³, the cause shall be investigated and corrective action implemented before the system is relied upon for normal odorous operations.  Corrective action may include media inspection/replacement, airflow balancing, ductwork repair, fan maintenance, increased local capture, operating-procedure changes or temporary suspension of the relevant activity. 5.0 Odour Sources, Risks and Operational Controls Source / activity Odour risk Normal control Abnormal response Vehicle / tanker opening and unloading Short-duration release of wastewater/septic/debris odour Unload inside enclosed building; extraction on; doors closed except essential access; minimise unloading duration. Suspend unloading if extraction/OCU unavailable. Waste decanting and screening/separation Potentially continuous process odour during activity Operate under negative pressure; local capture where required; route foul air to OCU. Stop activity if containment cannot be maintained. Temporary screened solids Odour increases with storage duration Keep contained; minimise retention time; remove off site as soon as practicable. Prioritise removal and clean affected area. Covered tanks / headspace Headspace displacement during filling/transfer Keep tanks covered; use closed/vapour-tight connections where practicable; route relevant headspace to OCU. Inspect seals/connections and repair leaks. Washdown and drains Organic residues and stagnant material Routine cleaning; drain flushing; prevent build-up; prompt removal of residues. Deep clean drains/process area and inspect drainage. Spills / loss of containment Potential intense local odour Spill prevention, rapid containment and clean-up; keep spill materials available. Suspend affected activity until spill is removed and area cleaned. OCU / fan failure Loss of treatment or negative pressure Duty/standby fans; alarm; preventive maintenance; spare critical items where practicable. Suspend odorous operations until restored. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Odour Management Plan 25.574 TE Rev 1 | 16 September 2026 Page 11 6.0 Odour Monitoring and Assessment 6.1 Monitoring Programme Monitoring activity Minimum frequency Location Key record Operator source-area check Daily when odorous processing is occurring Debris Reception Building / immediate process area Check for unusual odour, extraction operation, doors, spills and housekeeping. Boundary sniff assessment Weekly during representative operation BM1-BM4 fixed boundary locations Record wind direction/strength, odour character, intensity, persistence and likely source. Complaint-response assessment As soon as practicable following a credible complaint Complaint location / public-access receptor route plus site/boundary Follow AG5-style field methodology and source-attribution procedure. OCU / extraction operational check Each operating day Fans, alarms, ductwork, negative pressure, OCU Confirm operating status and identify faults before/during odorous activities. OCU performance verification At commissioning and thereafter when required by maintenance programme, planning requirement or investigation A1 / OCU system Verify airflow, system balance and treated outlet performance against the 400 OUE/m³ design basis. 6.2 Level 1 - Site Odour Assessment A trained operator will carry out a brief daily source-area sniff assessment when the facility is undertaking potentially odorous operations. The check will confirm whether odour is unusual for the activity, whether building extraction and the OCU are operating, whether doors are being managed correctly and whether spills, residues or drain conditions require attention. 6.3 Level 2 - Boundary / Receptor Assessment Four fixed boundary monitoring locations, BM1-BM4, are defined in Appendix C. These locations are selected to cover the northern, eastern, south/south-eastern and west/south-western sides of the site. The same safe standing points will be used consistently. Where a complaint investigation requires assessment nearer a sensitive receptor, observations will be made from safe public-access locations without entering private property unless permission is obtained. 6.4 Field Assessment Method Field assessments will follow an AG5-style approach using FIDOL principles: Frequency, Intensity, Duration, Offensiveness and Location. The observer will record weather conditions, wind direction and strength, observation location, odour persistence, intensity, character and likely source. Particular care will be taken to distinguish wastewater/septic/debris-type odour from livestock/manure odour associated with nearby piggeries.  The observer should be free from a cold, sore throat or sinus condition that could impair smell perception.  Avoid smoking, strongly flavoured food/drink and scented toiletries for at least 30 minutes before the survey.  Do not use an air freshener/deodoriser in the survey vehicle.  Record prevailing wind, recent rainfall, temperature and relevant site activities.  Where odour is detected, record intensity, persistence, character and potential source rather than recording only a yes/no result. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Odour Management Plan 25.574 TE Rev 1 | 16 September 2026 Page 12 7.0 Complaint Management and Source Attribution 7.1 Complaint Intake All odour complaints will be logged. The record will include, where available, the complainant contact details, location, date/time, duration, odour description, intensity, prevailing weather, and whether the complainant is willing to be contacted for follow-up. 7.2 Investigation Procedure 1) Check current and recent site activities, including waste receipt, unloading, screening, tank transfers, washdown and maintenance. 2) Check extraction/OCU operating status, alarms, negative-pressure condition and any abnormal events. 3) Review wind direction and the location of the complaint relative to A1 and other credible odour sources. 4) Undertake a boundary and, where practicable, receptor-area field assessment using the Appendix B record sheet. 5) Compare odour character with likely JC Environmental odours and other local sources, including livestock/manure odour from B1-B3. 6) Classify the complaint as confirmed, not confirmed, or requiring further characterisation; record the basis for the decision. 7) Implement corrective action where the site is identified as a credible source and verify effectiveness. 7.3 Source Attribution and Nearby Piggeries The occurrence of odour within the surrounding area will not automatically be attributed to JC Environmental. Source attribution will consider wind direction, receptor location, odour character, intensity, persistence, the operating status of JC Environmental and the presence of the three identified piggeries or other potential sources. A livestock/manure odour character will be recorded distinctly from wastewater/septic/debris-type odour. 7.4 Escalation and Corrective Action Repeated confirmed complaints, persistent boundary odour, a verified outlet-performance issue or recurrent equipment faults will trigger a formal management review. The review will identify root cause, corrective actions, responsibilities, completion dates and follow-up monitoring. Where necessary, odorous operations will be curtailed until effective control is demonstrated. 8.0 Preventive Maintenance, Housekeeping and Abnormal Events 8.1 Preventive Maintenance  Maintain the OCU, fans, ductwork, dampers, seals and alarms in accordance with the supplier preventive-maintenance programme.  Inspect treatment media condition and pressure/drop or other relevant performance indicators as recommended by the supplier.  Keep maintenance and fault records, including corrective work and return-to-service checks.  Confirm duty/standby fan availability and alarm functionality at planned intervals.  Inspect roller-shutter doors, tank covers and transfer connections for defects that could compromise containment. 8.2 Housekeeping and Waste-Retention Controls  Minimise the quantity and duration of potentially odorous material held on site.  Clean process surfaces promptly after spills or visible contamination.  Flush and clean drainage channels routinely to prevent persistent organic build-up.  Keep tanks covered and transfer connections closed/vapour-tight where practicable.  Keep doors closed during odorous operations except for essential vehicle or personnel access.  Remove screened solids and residues from the site as soon as reasonably practicable. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Odour Management Plan 25.574 TE Rev 1 | 16 September 2026 Page 13 8.3 Abnormal Events Abnormal event Minimum response OCU or extraction failure Stop odorous processing if containment cannot be maintained; close doors; investigate fault; record event; restart only when effective control is restored. Loss of negative pressure Check fans, doors, ductwork and extraction balance; minimise door opening; suspend odorous activity if unresolved. Spill / tank leak Stop transfer if safe to do so; contain and recover spill; clean area and drains; inspect cause before restart. Odour breakthrough Check OCU loading/media/airflow; review recent operations; undertake boundary check; implement maintenance/corrective action. Power failure Cease odorous processing and secure waste/tanks until extraction and OCU operation are restored. 9.0 Record Keeping, Training and Review 9.1 Records The following records will be retained as part of the OMP:  Daily source-area odour / operational checks.  Weekly boundary monitoring records.  Complaint logs and complaint-investigation field sheets.  OCU commissioning, airflow and performance-verification records.  OCU/fan inspection, alarm, fault and maintenance records.  Spill, abnormal-event and corrective-action records.  Relevant waste-retention / removal records where used to investigate odour events.  OMP review and training records. 9.2 Training Relevant staff will be trained in the requirements of this OMP, including closed-door operation, negative-pressure and OCU requirements, spill response, daily odour checks, complaint handling, field-observation recording and escalation of faults. Staff undertaking formal field odour assessments will be familiar with the Appendix B methodology and source-attribution requirements. 9.3 Review The OMP will be reviewed at least annually during active operation and following any significant process change, material OCU modification, repeated confirmed odour complaints, significant failure of the odour-control system, or a planning/regulatory requirement. Revised versions will identify the reason for change and the approval date. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Odour Management Plan 25.574 TE Rev 1 | 16 September 2026 Page 14 10.0 CONCLUSIONS  The receiving environment is mixed and includes nearby high-sensitivity residential receptors; it is not treated as predominantly agricultural.  The proposed waste-processing activities will be undertaken within the enclosed 192 m² Debris Reception Building under controlled extraction.  The building will be maintained under negative pressure during potentially odorous operations, with foul air routed to the OCU.  The minimum nominal whole-building extraction duty is 4,000 m³/hr, approximately 4.2 ACH for the estimated 950 m³ building volume.  The controlled discharge A1 uses a 7.45 m vertical stack with a 0.240 m outlet and calculated exit velocity of approximately 24.6 m/s.  The OCU shall achieve 400 OUE/m³ or lower during normal operation, corresponding to approximately 444 OUE/s at the adopted airflow.  The supporting conservative screening assessment predicts approximately 1.30-1.36 OUE/m³ at the identified residential receptors under the 400 OUE/m³ design case, below the adopted 1.5 OUE/m³ screening benchmark.  Three nearby piggeries are recognised as separate background odour sources and are considered explicitly during field observations and complaint source attribution.  Daily source-area checks, weekly fixed boundary monitoring and complaint-response field assessments are incorporated into this OMP.  Potentially odorous operations shall be suspended where extraction or OCU failure prevents effective containment and treatment.  Implementation of this OMP, together with commissioning, preventive maintenance and the 400 OUE/m³ OCU performance requirement, provides the operational framework for controlling odour from the proposed development.
