Mobuoy Remediation Project Todays Ask of Council Council to endorse - PowerPoint PPT Presentation

Mobuoy Remediation Project

Today’s Ask of Council Council to endorse engagement with DAERA/ NIEA to work in Partnership to co-design future development plans

Overview Site Overview Criminal Case Mobuoy Working Group – Follow up Waste Regulation Site History Protecting the Drinking Water Remediation Options Appraisal DAERA / Council Partnership to develop Site Vision Q&A

Mobuoy Criminal Case Ongoing criminal case; Trial date set for 7 th Sept 2020; Some project information is evidence in the criminal case; We remain limited in what information we are able to share at this point.

Council Mobuoy Working Group - Summary of Issues Raised 1. Provide an explanation of what happened & the extent of investigation; knowledge of extent and type of waste present; 2. Provide an update on the proposed Public Inquiry into all illegal waste in N. Ireland, what was done? 3. How to ensure Polluter Pays Principle is adopted; 4. What are the plans to deal with waste? What decisions have been taken in respect to remediation of the site? Has a preferred option been agreed? 5 Will drinking water will be safe? Can this be guaranteed without removing the waste? 6. Cost estimates appear to be wide ranging; can the Department confirm the estimated costs to remediate the site? 7.What would happen if the waste started to leach? 8. What are repercussions for the proposed A6 (Drumahoe to Stradreagh)? 9. There are reports the water treatment plant has been moved up above Mobuoy.

Response to Failure in Waste Regulation Implementation of Mills and CJI Action plans; Remediation Strategy for Mobuoy under development; Pro-active intelligence led approach to tackling waste crime under development; Regulatory Transformation Programme; Increased partnership working with councils to manage waste; Waste promotion and development of the Circular Economy;

Enforcement What's been achieved: Remediation Enforcement Strategy Cost Recovery Protocol and updated guidance Enforcement Technical Advisory Group Remediation enforcement through Environmental Liability (Prevention and Remediation) Regulations (NI) 2009 process

Protecting Drinking Water

NI Water’s abstraction from the River Faughan Raw water is abstracted from the River Faughan at approx. 2 miles downstream of the landfill site; Oil and Ammonia monitors with alarms ensure automatic shutdown;

Drinking Water Quality - how do we ensure we provide safe, clean drinking water?

Is Our Water Safe to Drink? YES The raw water and final water quality is monitored 24/7 at the Water Treatment Works (WTW); Daily analytical testing of raw water and final water samples; Daily samples are taken at customer taps to monitor water quality; Results are assessed against the requirements of the Drinking Water Regulations.

NI Water’s Contingency Measures Contingency Contingency measures in place to maintain continued supply of high quality drinking water; Contingency Plans in place for all of NI Water WTWs; Interconnectivity to two other WTWs to maintain supply to customers.

Objectives of the Mobuoy Monitoring Programme To protect water quality of the River Faughan; To determine the impacts of the waste on the underlying groundwater body and surface water bodies on site; To update the risk assessments and support NIEA’s enforcement actions; To inform the need for mitigation actions in advance of site remediation.

Overview of Mobuoy Monitoring Programme Programme is supported with new dedicated resources within NIEA’s laboratories; Leachate monitoring and groundwater monitoring; Surface water monitoring; Groundwater level monitoring; Landfill gas monitoring.

Developing the Remediation Strategy - Options Appraisal

Remediation Objectives Protect NI Water’s raw water abstraction and supply; Protect water quality of the River Faughan; Improve and remedy environmental damage; Reduce landfill gas risks to protect site users; Timely and continued engagement with stakeholders.

Appraisal of Remediation Options – Sustainable Remediation Forum UK (SuRF-UK)

Framing the remediation options appraisal • Local stakeholder engagement events on 8 Feb. & 24 Mar. 2017 & with Gov. Agencies on 25 Jan. and 4 Apr. 2017; • Stakeholder questionnaire survey; • Local industrial/regulatory knowledge. • Scoring criteria for economic, environmental and social factors on an equal basis; • Site-specific decision matrix of viable remediation options; • Identified priorities for the selection criteria and decision making.

Other er issues es r raised ed • Very strong feeling that lessons should be learnt to prevent recurrence; • The critical sensitivity of River Faughan to short term impacts is recognised; • The desire for a beneficial end use, with a particular focus on ecology was expressed; • There are still uncertainties regarding control of future end uses; • Strong sense that those responsible for the waste deposition shouldn’t benefit from remedial works.

Stage 1: Shortlisting of Options Options Screening Assessment: Identified range of potentially Options considered for each waste applicable remediation techniques; zone and for the whole site assessed on the basis of;  Direct treatment of wastes (3) Applicability; Permissibility ;  Containment options (5) Sustainability ; Time;  Leachate management options (8) Cost was not included as a decision factor at the shortlisting  Pathway barriers (4) stage; Options that scored zero in any  Source treatment options (13) shortlisting not taken forward Small Business Research Initiative (SBRI) – funded Phase 1 of 5 potential emerging remediation technologies (October 2016 to March 2017)

Stage 2: Detailed Assessment of Options By waste source zone & for the whole site; Weighted scoring system based on stakeholder consultation; Decision by multi-criteria analysis; Budget cost estimates for each shortlisted option considered; Provides for sensitivity analysis and uncertainty.

Integrated Remediation  Integration of options to manage All risks across the site;  Integrated approach needed to take account of DAERA, DfI and NI Water’s interests;  Contingency for failure of certain elements or impact due to climatic variability;  Management of system capacity and maintenance;  Addressing specific waste / site issues

Remediation Strategy – Next Steps Final Costed Remediation Strategy subject to: Remediation • review & update of options via a new Options Appraisal ICT contract; • integration with NI Water’s contingency plans & the A6 scheme (Drumahoe to Stradreagh); • Identify feasible • approval of the business case. options Detailed evaluation of • options • Strategy to provide combination of • Develop & agree the the highest performing options to Remediation Strategy manage risks and support site vision
