Health and Safety issues FOG Guidance Document Launch Seminar 26th January 2012

Code of Practice for entry to Confined Spaces FOG Guidance Document Launch Seminar 26th January 2012

Background  Growth in sector during  80% of FOG related blockages occurring in areas with high concentration of FSE  Only 2% of FSE with adequate grease trapping equipment  Limited resources available to tackle problem

FOG Guidance Document Launch Seminar 26th January 2012 The Solution  Prevention at source  DCC launch FOG programme 2008  Locate, identify and survey all FSE  Ensure all FSE hold a Trade Effluent Licence  Ensure grease trapping equipment is sized appropriately  Ensure grease trapping equipment is maintained  Promote Good Kitchen Practice

FOG Guidance Document Launch Seminar 26th January 2012 The Solution (continued)  Regular environmental inspections to ensure compliance  Focus on problem areas  Enforcement of non-compliances  Cost of implementation of programme borne by FSE (Polluter Pays Principle)

FOG Guidance Document Launch Seminar 26th January 2012 Challenges Faced - Resistance to FOG programme - Use of additives - Inadequate grease trapping equipment - Confusion over sizing of grease traps

Challenges Faced Large number of undersized grease trapping equipment installed FOG Guidance Document Launch Seminar 26th January 2012

Additives - Chemicals / surfactants / emulsifiers not acceptable - Bacteria acceptable in conjunction with passive grease trap - Introduction of testing and permitting of bacteria products FOG Guidance Document Launch Seminar 26th January 2012

Typical Quantity of FOG produced per FSE type (Litres per year) - Full Service Restaurant – 828 litres - Hospital – 2352 litres - Fast Food Restaurants – 906 litres - Company/Office Canteen – 1212 litres - Hotel – 1596 litres - Convenience Store/Deli – 232 litres - Nursing Home – 276 litres - Public House – 624 litres FOG Guidance Document Launch Seminar 26th January 2012

Poor Kitchen Practices Waste oil stored in uncovered drums not in bunded area FOG Guidance Document Launch Seminar 26th January 2012

Poor Kitchen Practices FOG Guidance Document Launch Seminar 26th January 2012

Structure of 2008 – 2011 Contract - Schedule of rates - Excellent for the initial survey of FSE - Routine monitoring minimum four times per year FOG Guidance Document Launch Seminar 26th January 2012

Progress to date - Approx 2,100 FSE - Over 22,000 environmental inspections carried out - 90% of FSE currently licensed - 74% of licensed premises compliant - Approx 1,100 tonnes of FOG prevented from entering drainage network in 2011 FOG Guidance Document Launch Seminar 26th January 2012

Progress to date - Significant reduction in the number of JetVac hours spent on call outs to FOG- related blockages - No major blockage requiring man-entry to sewer since March 2010 FOG Guidance Document Launch Seminar 26th January 2012

Enforcement - Commenced legal action against non- compliant FSE in mid 2010 To Date: prosecutions initiated - 10 convictions cases settled out of court - 40 currently in system FOG Guidance Document Launch Seminar 26th January 2012

Annual Licence Charges - Cost of implementation borne by FSE – 2010 fixed charge per type of FSE introduced incentivised payment scheme - Risk based approach with annual charges ranging from €315 - €1255 FOG Guidance Document Launch Seminar 26th January 2012

Best Practice - Regular inspections necessary to ensure compliance - Clear guidance and information must be given to FSE operators - Correct sizing of grease traps very important - Good record keeping very important - Enforcement necessary for successful programme - Positive response to incentivised charging structure FOG Guidance Document Launch Seminar 26th January 2012

Phase 2 / Moving Forward - New contract commenced January Contract to supply suitably qualified resources gives DCC more flexibility & price certainty - Managed in-house - Positive engagement with food industry groups - Better use of IT - FSE also inspected for compliance with Food Waste Regulations - Potential to share services between local authorities FOG Guidance Document Launch Seminar 26th January 2012
