handling and container changes to a minimum to reduce waste generation and potential handling spills. The quantity of finished product stored on site will be in the region of 2,000 tonnes. In addition, a number of additional tallow tanks will be used to store tallow. Thirteen of the tanks will be placed in a general bunded area or tank farm covering an area of 1,622 m2 as shown on Appendix H.1.1 depicting the proposed site layout. The methanol and gas oil tanks will be stored in their own bunded areas within the tank farm as shown on Appendix H.1.1. Both the sulphuric acid and phosphoric acid tanks will be placed together in a separate bunded area within the tank farm. The nitrogen storage tank and the fertiliser silo will be stored in separate areas as shown as shown on Appendix H.1.1. Potassium hydroxide (KOH) (catalyst) together with used KOH big bags will be stored in the main process building. Chemicals will be transferred to and from the process building via an enclosed piped system, the schematic of which is shown on Appendix H.1.2 (with enclosed stream list and equipment list codes). (Note: The information on the pipeline system is considered confidential and as such is presented separately in an envelope). The storage tanks are designed in accordance with latest guidance on energy efficiency, environmental protection and as such represent BAT for materials storage. Table 1 below outlines the storage and list of raw materials, finished products and ancillary materials on site. An internal dedicated chemical store will be used to store all dry materials. This is primarily potassium hydroxide. Drums where used will be properly secured and provided with adequate drip trays.

3.0 MOVEMENT OF MATERIALS ON SITE Materials will move on site via enclosed pipelines within the process building as well as to and from the tank farm. BioDiesel will also be piped to the wharf at Marshmeadows. 3.1 Tank Farm – Loading and Unloading

BioDiesel storage FME (fatty acid methylester) the main product of the BioDiesel process is alternately collected with additives in a BioDiesel quality tank containing a capacity of 200 m³. The BioDiesel complying with the European BioDiesel standard (ascertained by analysis) is pumped from this quality tank to two dedicated long term storage tanks with a capacity of 1000 m³. Finally, BioDiesel from any BioDiesel tank can be loaded to road tankers by the top loading device at the loading station. All BioDiesel storage tanks are equipped with heating coil and with thermal insulation.

Feedstock storage The feedstock is firstly pumped from the unloading station (incoming road tankers) or through the pipeline to any of the raw material storage tanks (capacity of each 200 m³). Tanks are equipped with heating coils to prevent plugging of the feedstock at lower (ambient) temperatures. All feedstock tanks are also equipped with thermal insulation.

Feedstock from ships is pumped into one of the two 1000 m³ storage tanks. Road tankers unload at the designated unloading station on the site while the ship

unloading station takes place at the jetty. Tank farm and port are connected with a pipeline system. Tallow/RVO storage tanks are featured with thermal insulation and a heating coil for an appropriate use.

Crude Glycerine Crude Glycerine, one of the side products of the BioDiesel process, is stored in a dedicated tank with a capacity of maximum 160 m³. The tank is equipped with a heating coil and thermal insulation. Loading is executed by a separated top loading device at the loading station. Fertiliser Fertiliser, another side product, is conveyed to a 25-tonne silo from where it is bagged off, in powder format, into 1-tonne bags and stored undercover for shipment. Potassium hydroxide (KOH) Potassium hydroxide (KOH) is used for the preparation of MEK. The potassium hydroxide (KOH) is delivered in Big-Bags with a weight of about 1000 kg. The transfer to the MEK preparation takes place by fork lift truck and by hoist. Sulphuric acid Sulphuric acid is stored in a dedicated storage tank with a capacity of 25 m³, which is located in a separate bund. The unloading process from the road tankers takes place at the unloading station. Bio-Heating Oil Bio-heating oil side product is stored in a storage tank with a capacity of 40 m³. The tank is equipped with a heating coil and thermal insulation. Gas Oil Gas Oil is stored in a dedicated storage tank with a capacity of approx. 50 m³ and is located in a separate bund. Methanol Methanol is stored in a dedicated storage tank with a capacity of 100 m³, which is erected in a separate bund. The unloading from the road tankers takes place at the unloading station. By filling the storage tank the displaced gas volume is vented back to the emptied road tanker by a separate pipe. There are no emissions of evaporated liquid. The flame arrestor at tank ventilation guarantees that the displacement of gases will take place by having a certain pressure loss.

Nitrogen The nitrogen system consists of a liquid nitrogen storage tank with a capacity of 10 m³. The system is equipped with a vaporizer to supply the plant with gaseous nitrogen. Filling of the tank takes place by the road tankers. Loading system The BioDiesel is pumped from one of the 2 no. 1000 m³ storage tanks to either a road tanker or boat. The road tankers are filled by movable top loading arms. A flow meter counts the amount of the loaded product. A maximum level switch stops the loading procedure for safety reasons.

3.2 Tank Farm to Wharf Connection

BioDiesel will be piped to the wharf at Marshmeadows through a system of pipelines from the tank farm at the GBI facility. It is estimated that they will be used for approximately one import / export per month. The pipelines will be full of product for a period of approximately 6 hours during pumping and will be entirely emptied upon completion of this activity. These pipelines will be constructed of schedule 40 welded heavy-duty steel with pressure testing on completion. They will also be trace heated and insulated as required. The integrity of the pipes will also be tested annually.

3.3 Piping and Reaction Vessels 3.3.1 Piping

All pipelines installed will be in accordance with BS 8000:1989 Part 14, BS 8010: Code of Practice for Pipelines and BS 8301:1985 Code of practice for Building Drainage.

Pipeline connections and monitoring

Outside the process building the piping system to the tank farm, loading/unloading station, methanol tank and to the fire extinguishing basin is mounted on pipe bridges. The pipe bridges are installed at a sufficient height above ground to avoid damage and enable leaks to be visible. The pipe bridges are steel constructions with reinforced concrete pedestals. The extension compensating of the pipes is realized with clamps on movable bearings and with compensators. For equi-potential bonding the pipe bridge is connected with the grounding system. All pipe joints (e.g. flanges) are only situated either inside the tank wall or the process building, both equipped with spill containment to prevent run-off into drains. Continuous pressure monitoring and alarm systems are established to detect accidental spillage during transfer of materials. Pipeline material Material of pipes depends on the medium. The listed pipe classes are referring to a certain standard of material. All available pipe material is mentioned in the list of ‘Pipe classes’ shown below. The required material is a result of the medium inside.

Pipe class / PN / Material of pipes 111 / PN 10 / (EN10088/1-3) 114 / Vakuum / 1.4301 (EN 10088/1-3) 122 / PN 10 / 1.4571 (EN10088/1-3) 132 / PN 10 / 1.4539 (EN10088/1-3) 152 / PN 10 / Hastelloy 161 / PN 10 / S235JRG2 (St.37.0) 172 / PN 10 / PVDF 243 / PN 16 / P235G1TH (St.35.8) 343 / PN 25 / P235G1TH (St.35.8) 443 / PN 40 / P235G1TH (St.35.8) 920 / PN 200 / 1.4571 Ermeto

Corrosion protection Basically in the BioDiesel plant the pipelines are made of stainless steel with exemption of pipelines for steam and hot water, which are made of carbon steel. These pipes are sand blasted and coated with primer and are to be insulated. Heat insulation Due to technical, economical and safety reasons all pipes with extraordinary hot or cold surfaces are thermally insulated. Thereby the thickness and type of insulation depends on the diameter of the pipe and the difference in temperature as well (see below mentioned list is referring separately to hot and to cold pipelines). The standard design of insulation is with Rockwool and cladding with aluminium sheets. Heating Some raw materials and some co-products of the BioDiesel process tend to solidification at lower temperatures (e.g. ambient temperatures). To prevent certain media from solidification the related pipelines are equipped with heat tracing.

In hazardous areas there are used self-limiting heating tapes with a temperature controller. In non hazardous areas, flexible single core heating cable with a temperature controller and an overheating protection are used. Self-limiting heat tracing The power consumption of the self-limiting cable is adjusted in relation to the surface temperature and ambient temperature. The temperature increases the resistance increase in the cable. As consequence the power consumption decreases with increasing temperatures. Additionally the self-limiting cable can be equipped with a temperature controller. Because of the parallel power supply the heating tape can be cut to any required length. Flexible single core heat tracing The flexible single core heat tracing is used for heating of large surfaces to provide appropriate process temperatures, viscosities of media and other conditions. The design is based on a silicon rubber lamination technology. The single core heat tracing is available in a variety of configurations including: drum heaters, tapes, blankets of many sizes with and without adhesives. Drum heaters and some tapes are equipped with integrated thermostatic controllers. Blankets and other tapes require a temperature controller. Approximate diameter of pipelines All pipes of the BioDiesel plant have to comply with ISO class I. The pipe material is specified in accordance with DIN in the following table e.g. 1.4301 = AISI 304; 1.4571 = AISI 316L; 1.4539 = 904L; St 37.0 = carbon steel low quality for hot water; PVDF = Teflon for acids; St 35.8 I = for steam pipes. 3.3.2 Reaction Vessels and Pressure Testing All implemented simple pressure vessels and pressure vessels comply with legal requirements regarding design and manufacture according to the European Pressure Equipment Directives. For this purpose the vessels are verified by pressure tests as well as weld strength. The vessels are featured with a name plate containing details about maximum operating pressure and temperature,

volume, medium, manufacturer as well as factory-number. The vessels are resistant against their contents and are equipped with level control and an overfill protection. Simple pressure vessels ‘Simple pressure vessels’ are any welded vessel subjected to an internal gauge pressure greater than 0.5 bar which is intended to contain air or nitrogen and which is not intended to be fired. The parts and assemblies contributing to the strength of the vessel are made either of non-alloy quality steel or of non-alloy aluminium or non-age hardening aluminium alloys. The materials used for manufacturing the pressurized components are capable of being welded, ductile and tough, so that a rupture at minimum working temperature does not give rise to either fragmentation or brittle-type fracture and it is not adversely affected by ageing. All un-pressurized components of welded vessels are of materials which are compatible with that of the parts to which they are welded. According to the harmonisation of the laws of the Member States relating to simple pressure vessels (87/404/EEC) all vessels used in the BioDiesel plant meet the standards in terms of certification procedures, EC conformity and marking. Pressure vessels Pressure vessels are made for loadings appropriate to its intended use and other reasonably foreseeable operating conditions. The method of operation specified for pressure equipment is such as to preclude any reasonably foreseeable risk in operation of the equipment. Based on calculations according to AD2000 the vessels used in the plant are up to the Directive of pressure equipment (97/23/EG) and therefore conform to international standards. All pressure vessels delivered by BioDiesel International suppliers are already certified and ready for installation. If necessary, adequate protection against corrosion or other chemical effect is provided, taking due account of the designated use. Adequate measures (e.g. appropriate design, additional material thickness as well as cladding materials) are taken to avoid conditions of erosion or abrasion. Final acceptance of pressure vessels includes a technical inspection for the pressure containment aspect, usually in form of a hydrostatic pressure test.

4.0 BUNDED STRUCTURE MANAGEMENT All liquid wastes and potentially hazardous wastes will be stored either inside the main building, in dedicated containers, or in the bunded tank farm. Furthermore, all areas of the proposed site at Marshmeadows, New Ross will be concrete surfaced, with surface water discharging via a high specification interceptor system. The process building is also designed within a bund. All spillages are collected in the catchpit of the process building and pumped to the wastewater tank. The tank farm bund and methanol bund walls are designed as water retaining concrete structures to BS 8007:1987 to accommodate 25% of the total tank volume in accordance with CIRIA report 163. The contents of the IPPC Guidance Note prepared by the EPA on Storage and Transfer of Materials for Scheduled Activities will be noted. There is no direct connection from the bunds to the drainage system under normal conditions.

GENERAL PROPERTIES1. Gaseous nitrogen is colourless, odourless and tasteless and

is slightly lighter than air at equal temperatures; coldnitrogen vapour is, however, denser than atmospheric air.

2. Liquid nitrogen is odourless, colourless and boils at -195.8°C. One volume of liquid nitrogen givesapproximately 700 volumes of gas at ambient conditions.

3. Nitrogen is not flammable. It is chemically inert, except athigh temperatures and pressures. Its volume concentrationin air is 78%.

4. Liquid nitrogen and cold gaseous nitrogen can cause severeburns or frostbite when in contact with the skin orrespiratory tract.

5. Nitrogen is non-corrosive, non-toxic, does not support lifeand acts as an asphyxiant.

SAFETYThe following information is for guidance of customers usingnitrogen. It is strongly recommended that users know andunderstand the properties of the gas before handling it.

FIRE AND EXPLOSION HAZARDSNeither gaseous nor liquid nitrogen is flammable and does not initself constitute a fire or explosion risk. However, both gaseousand liquid nitrogen are normally stored under pressure and thestorage vessels, whether gas containers or liquid tanks, shouldnot be located in areas where there is a high risk of fire or wherethey may normally be exposed to excessive heat. Containerscontaining compressed gaseous nitrogen may rupture violently ifoverheated as a result of exposure to fire.At equal pressures the boiling point of liquid nitrogen is lowerthan that of liquid air. Air will condense on the external surfacesof vessels or pipework containing liquid nitrogen at anequilibrium pressure less than 1.5 bars absolute if the vessels

are either unlagged, or lagged with a porous cellular typeinsulant.

The liquid air produced can result in oxygen enrichment of theatmosphere local to the equipment. Special precautions musttherefore be taken with regard to the insulation of the vesselbefore any maintenance or repair work is started, particularlywhere the use of open flames or other potential sources ofignition is intended.

MATERIAL HAZARDSCertain steels such as carbon steel and some other materials areunsuitable for service at sub-zero temperatures because theylose impact strength and become extremely brittle. Carbon steelcannot be used safely at temperatures below -30°C (-20°F) andis obviously unsuitable for service with liquid nitrogen. Materialsnormally suitable for service at low temperatures are theaustenitic stainless steels, aluminium and copper and its alloys.In an area where liquid nitrogen spillage can occur, care shouldbe taken to ensure that the liquid does not come into contactwith vulnerable steel structures and vehicle tyres. Care should betaken to ensure that liquid nitrogen and cold nitrogen vapour arenot trapped in a closed system without any form of automaticpressure relief. Otherwise pressures well in excess of theequipment working pressure will be generated as the systemwarms up, thus creating a possible rupture hazard.

HEALTH HAZARDSAsphyxiaNitrogen, although non-toxic, can constitute an asphyxiationhazard through the displacement of the oxygen in theatmosphere. The potential for this type of hazard is significantbecause of the widespread use of nitrogen as a purging orblanketing gas in chemical, metallurgical. and other industrialoperations and because neither nitrogen gas nor oxygendepletion are detectable by the normal human senses. Unlessadequate precautions are taken, persons can be exposed tooxygen deficient atmospheres if they enter equipment or areaswhich have contained or have been purged with nitrogen.

BREATHING A PURE NITROGEN ATMOSPHERE WILL PRODUCEIMMEDIATE LOSS OF CONSCIOUSNESS AND ALMOSTIMMEDIATE DEATH.

Cold burnsLiquid nitrogen and cold nitrogen vapours or gases can produceeffects on the skin similar to a burn. Naked parts of the bodycoming into contact with uninsulated parts of equipment mayalso stick fast (because all available moisture is frozen) and theflesh may be torn on separation.

FrostbiteSevere or prolonged exposure to cold nitrogen vapour and gascan cause frostbite. Local pain usually gives warning of freezingbut sometimes no pain is experienced. Frozen tissues arepainless and appear waxy with a pallid yellowish colour. Thawingof the frozen tissues can cause intense pain. Shock may alsooccur if the burns are at all extensive.

Effects of cold on lungsProlonged breathing of extremely cold atmospheres may damagethe lungs.

HypothermiaLow environmental temperatures can cause hypothermia and allpersons at risk should wear warm clothing. Hypothermia ispossible in any environmental temperature below 10°C (50°F).

PRECAUTIONSOperation and maintenanceIt is essential that operations involving the use of gaseous orliquid nitrogen, particularly where large quantities are used, are

N2 %nitrogen plus inert rare gases (guaranteed by % volume) >99.999oxygen (guaranteed ppm by volume) <5water (guaranteed ppm by volume) <2Typical Analysis (by volume)nitrogen 99.999%oxygen <2ppmwater <1ppmCarbon dioxide/carbon monoxide/nitrous oxide/hydrocarbons/methane/acetylene

These impurities maybe present in trace

quantities

The information within this guidance note is believed to be accurateand is given in good faith. It is for the user of the gas to determinethe correct approach to safe use of the gas and the actions to takein any site emergency involving a release of the gas.

Information on all gases supplied by Air Products can also be foundin the material safety data sheets issued to all customers.

conducted in well ventilated areas to prevent the formation ofoxygen deficient atmospheres.

Ideally, nitrogen should be vented into the open air well awayfrom areas frequented by personnel. Nitrogen should NEVER bereleased or vented in enclosed areas or buildings where theventilation is inadequate.

Before entering areas, vessels or other equipment formaintenance (or other purposes in which the atmosphere is, ormay become, deficient in oxygen) action should be taken tomake the equipment safe. Preparatory work will includeequipment isolation from hazardous processes, purging andcontinued ventilation with air as appropriate. Equipment inservice with flammable gases should be purged with nitrogenprior to purging with air to avoid the formation of flammablemixtures.

Prior to entry, the atmospheres should be tested with a portableoxygen analyser (calibrated before use) to ensure that theoxygen content lies between 20% and 22% by volume. The useof a safety work permit system is strongly recommended. Itshould be recognised that although nitrogen is slightly lighterthan air at equal temperatures, liquid nitrogen and cold nitrogenvapour are denser than air and can accumulate in low lying areassuch as pits and trenches. Where large spills of liquid nitrogenoccur, a fog is formed in the vicinity of the spill caused by thecondensation of water vapour in the surrounding air. The fog, inaddition to severely reducing visibility, may contain oxygenconcentrations appreciably lower than that of air, thus presentinga local asphyxiation hazard.

Personnel protectionIt is recommended that persons handling gas cylinders shouldwear safety glasses, safety footwear and clean, stout gloves.

Persons handling equipment in service with liquid nitrogenshould wear protective face shields, loose fitting leather orinsulated gauntlets.

EMERGENCIESIn the event of accident or emergency, the instructionsbelow should be implemented without delay. Afteremergency action has been taken, contact Air Products forfurther advice.

AsphyxiationPersons showing symptoms of oxygen deprivation should bemoved immediately to a normal atmosphere. Persons who areunconscious or not breathing must receive immediate first aid.Medical assistance should be summoned without delay. First aidmeasures include inspection of the victim’s airway forobstruction, artificial respiration and simultaneous administrationof oxygen. The victim should be kept warm and resting.

It is important to note that personnel carrying out rescueoperations must minimise the risk to themselves.

A RESCUER SHOULD NOT ENTER AN OXYGEN DEFICIENTATMOSPHERE WITHOUT USING SUITABLE SELF-CONTAINEDBREATHING APPARATUS, OTHERWISE HE MAY HIMSELF BEOVERCOME.

Many double fatalities have occurred in industry as a result ofpersonnel who, with the best intentions but without properbreathing apparatus and equipment, have entered an oxygendeficient atmosphere in an attempt to rescue a colleague.

Treatment of cold burns and frostbiteCold burns should receive medical attention as quickly aspossible. However, such injuries are not an everyday occurrenceand doctors, hospital staff or works first aid personnel may notbe aware of the basic methods of treatment. The following notes

describe the first aid treatment and recommended advice forfurther treatment to be given by a medical practitioner or ahospital.

1. First aidIn severe cases summon medical attention at once. Flushaffected areas of skin with copious quantities of tepid water toreduce freezing of tissue. Loosen any clothing that may restrictblood circulation. Move the victim to a warm place but not to ahot environment and do not apply direct heat to the affectedparts. Every effort should be made to protect the frozen partsfrom infection and further injury. Dry, sterile, bulky dressingsmay be used but should not be applied so tightly that bloodcirculation is restricted.

2. Treatment by medical practitioner or hospitala) Remove any clothing that may constrict the circulation to

the frozen area. Remove patient to sick bay or hospital.

b) Immediately place the part of the body exposed to thecryogenic material in a water bath which has a temperatureof not less than 40ºC (1O4ºF) but not more than 45ºC(113ºF). (See below for exceptions to this recommendation).NEVER USE DRY HEAT OR HOT WATER. Temperatures in excess of 45ºC will superimpose a burnupon the frozen tissue.

c) If there has been massive exposure to the super-cooledmaterial so that the general body temperature is depressed,the patient must be re-warmed gradually. Shock may occurduring re-warming, especially if this is rapid.

d) Frozen tissues are painless and appear waxy with a pallidyellowish colour. They become painful, swollen and veryprone to infection when thawed. Therefore do not re-warmrapidly if the accident occurs in the field and the patientcannot be transported to hospital immediately. Thawingmay take from 15 to 60 minutes and should be continueduntil the blue, pale colour of the skin turns to pink or red.Morphine or some other potent analgesic is required tocontrol the pain during thawing and should be administeredunder professional medical supervision.

e) If the frozen part of the body has thawed by the timemedical attention has been obtained, do not re-warm.Under these circumstances cover the area with dry, steriledressings with a large, bulky, protective covering.

f) Administer a tetanus booster after hospitalisation.

HypothermiaPersons suspected to be suffering from hypothermia should bewrapped in blankets and moved to a warm place. Slowrestoration of temperature is necessary and forms of locallyapplied heat should not be used. Summon medical attention.

Fire fightingNitrogen is not flammable and no special fire fighting precautionsor equipment are needed. If an outbreak of fire occurs in thevicinity of nitrogen storage equipment the local fire brigadeshould be summoned at once. Unless containers containingcompressed gaseous nitrogen can be removed safely to anunaffected area every effort should be made to keep them coolby spraying them with large quantities of water.

Liquid nitrogen spillageIf large spills of liquid nitrogen occur, large quantities of watershould be used to increase the rate of liquid vaporisation.Vehicles involved in a heavy liquid spillage should not be movedas the tyres may be frozen to the ground and the rubber will bebrittle.

1.0 INTRODUCTION This section of the IPPC Licence application details information on waste materials generated at the Green Biofuels Ireland Limited (GBI) site, including name, description and nature as well as the source(s) of waste and handling arrangements. The process at the (GBI) facility is designed to minimise any waste generated. A small amount of waste will be produced from offices and general day to day activities at the site. This will mainly consist of packaging and canteen waste. However raw materials will generally be delivered by tanker, thus minimising packaging waste. There will be no reject finished product as material will be returned to the distillation process for further distillation if necessary. 2.0 WASTE ARISINGS & STORAGE 2.1 Waste Arisings The plant and process design to be implemented by GBI has been developed to ensure waste generation is minimised at source, as far as possible. The focus of the waste management aspects of the Environmental Management System (EMS) to be implemented will be to ensure that those wastes arising which cannot be reduced or eliminated through changes to plant design and operation will be dealt with in an appropriate manner. GBI activities associated with the installation will generate both solid and liquid wastes. The wastes likely to be generated, the activities generating them and the fate of each waste stream are summarised in Table 1 below, as well as the waste code according to European Waste Catalogue 94/3/EC. Each waste is further categorised into either Hazardous or Non-Hazardous, as far as practicable, as defined in the Waste Management Act, 1996 to 2003. As the facility is not yet operational, there is no empirical data on waste quantities. However, some indication can be gained from the experience of the plant suppliers, BioDiesel International (BDI), at other BioDiesel plants they have constructed. These are also indicated below where possible.

2.2 Waste Storage The GBI production process is designed ecologically. By-products are purified and surplus material streams are led in a closed circuit, e.g. the free fatty acids from the glycerine phase are esterified into methyl ester, the excess methanol is purified and reused in the process. Therefore the amount of waste is limited. All liquid wastes and potentially hazardous wastes will be stored either inside the main building, in dedicated containers, or in the tank farm. All waste stored will be clearly labelled and disposed of / recovered according to waste management procedures. A list of the potential waste arisings and proposed waste storage areas for the GBI facility is presented below:

o Waste KOH bags (within KOH room); o Waste metals and lubrication oil from maintenance (in workshop); o Laboratory waste (within lab); o Interceptor cleaning waste (suctioned directly out of interceptor); o Dirty rags and gloves (workshop); o Batteries and fluorescent tubes; (workshop); o Canteen waste (designated area); o Spent Deionisation concentrate (utilities building); o Spent K2SO4 filters (workshop); o General office waste (designated area); o Paper, cardboard, plastic which may arise (designated area); o Organic and inorganic fluid waste which can arise from maintenance and

repair of process (stored in 200 lt drums in the process area) Appendix H.2.1 contains a plan of waste storage areas for the above waste arisings. Waste streams will be stored in segregated bins or suitable containers such as individual chemistores. Bins / containers will be in good condition and free from corrosion or wear, and located on good quality surfaced and level ground if not within the process building. Access to waste storage bins will be controlled and they will be sign-posted to specify permitted and prohibited wastes. They will also be checked regularly to ensure that only permitted wastes are being deposited in them as agreed with the approved waste contractor. 2.3 Wastewater Storage –Temporary Arrangements

In the short term, wastewater will be stored in Tank No. 19 and regularly pumped to a tanker and disposed of at Wexford County Council’s Wastewater Treatment Plant for Wexford Town, together with sanitary waste which will be pumped from a holding tank into Tank No. 19. This is because the wastewater treatment works for New Ross town and Environs on an adjoining site at Marshmeadows will not be built before the BioDiesel plant is expected to come on-line. The waste from the proposed GBI facility will be tested regularly during the commissioning phase.

All connections between storage and transportation will be secured and procedures will be implemented to ensure that the operation is attended by trained personnel at all times.

3.0 MANAGEMENT OF WASTE MATERIALS Most materials brought onto the GBI site are in bulk, thereby minimising the amount of packaging wastes. The closed nature of the production process and small numbers of personnel on site will help to keep waste emissions to a minimum. GBI will retain accurate records of the type and volume of general and special waste generated by the BioDiesel plant. All waste streams will be managed to ensure compliance with relevant environmental legislation and in such a way that no significant environmental impacts are associated with the wastes whilst on site. 3.1 Overview The main environmental aspects associated with on site waste management are the potential for wastes to spill or to be entrained in rainwater and hence contaminate the drainage system or to become a nuisance such as windblown litter impacting on neighbouring land. Emissions to air may also occur with dusty wastes or if a chemical reaction occurs by mixing acidic and other wastes. These potential releases will be avoided through effective management and storage of waste materials, and appropriate process design. In terms of off-site impact, there is the potential, if the wastes are mismanaged, for them to be disposed of to unlicensed facilities or fly-tipped. However, the waste management and tracking systems to be put in place by GBI will eliminate this possibility. There are not expected to be any significant differences in the types of wastes generated during the commissioning phase. Any sub-standard BioDiesel produced during trials will be recycled back into the process. The plant will utilise waste materials therefore the overall impact on the waste infrastructure in Ireland can only be viewed as positive. 3.2 General Provisions GBI will ensure that all wastes are stored in appropriate containers, clearly sign posted, and are placed in designated, properly contained areas and that all staff are aware of the correct storage arrangements. All staff will have a clear understanding of which wastes can and cannot be placed in certain areas or receptacles. Appendix H.2.1 shows a plan of the proposed waste storage area on the GBI site. GBI will:

o Implement a system for recording production and disposal of different waste types;

o Designate a responsible person(s) for the storage, handling, on-site treatment and disposal of all wastes generated on the site and provide training and instruction on the objectives and tasks of the role;

o Draw up a written procedure and programme of regular, documented inspection of waste storage areas to ensure that only appropriate wastes are being stored in the respective areas and that quantities of wastes stored are kept to a practical minimum; and

o Ensure that waste disposal cannot occur without it being co-ordinated by the facility’s designated waste manager.

All waste arisings at the site will be identified by provenance, quantity and type, and the amounts produced should be minimised to the extent that this is practicable in the context of the business.

3.3 Duty of Care All waste materials produced at the site will be properly handled, stored and managed, so as to prevent their release to the environment, until such time as they are collected by registered or exempted waste carriers for treatment or disposal at properly licensed waste facilities. Responsibility for adequate waste management disposal, including documentation and disposal arrangements, rests with GBI and will not be deferred or delegated to waste contractors. GBI will, under its compliance with the duty of care requirements of the EPA Act 1992, and Protection of the Environment Act 2003, ensure the following is adhered to:

• All wastes, whether regular arisings or one-offs, will be identified and characterised for adequate disposal in line with waste transfer purposes;

• All wastes will be stored and handled so that they cannot ‘escape from the control’ of the company or other parties involved in the disposal chain (i.e. drums will be sealed, bins kept covered etc);

• The contractor used to dispose of the waste is a registered waste carrier, or is legally exempt. The contractor must produce evidence to this effect and GBI will contact the EPA to confirm that the details the contractor has provided are accurate and correct;

• Properly completed waste consignment notes will be produced and maintained;

• The disposal, treatment or transfer facility(s) used for its wastes will be checked to ensure that it is properly licensed or legally exempt to accept those wastes. Further confirmation of this will be checked with the EPA.

When selecting a new waste contractor, GBI will not rely on the price of the contractor’s bid alone, but will also examine and test the contractor’s understanding of and compliance with duty of care and other legislation. Duty of care training and instruction will be given to all new employees and existing employees that either generate or handle wastes. As part of the company’s EMS and environmental audit, GBI will:

• Assess the commitment of the company to good waste management practice; • Check that the information gained by the facility operators is sufficient to be

able to treat / dispose of the waste properly and without risk to health, safety and the environment;

• Ensure that any spills, leaks, air emissions, drainage of wastes or by-products are controlled, so that they are not having any adverse environmental impact; and

• Ensure that the site is managed in a way that complies with legislation governing its operation.

3.4 Hazardous Waste Management GBI recognise that problems and uncertainties may arise when attempting to define whether certain wastes are sufficiently hazardous to be classified as such. In these instances, the identification of these substances as hazardous wastes or otherwise will be agreed with the EPA. If in doubt the waste will be consigned as hazardous

waste. All liquid wastes and potentially hazardous wastes will be stored either inside the main building, in dedicated containers, or in the tank farm. All hazardous waste will be stored to minimise the risk of escape and release into the environment or risk to the health of people on-site.

• All waste containers will be in good condition and not subject to corrosion or wear.

• Liquid waste containers will be secondarily contained in a bunded area, with the capability of holding 110% of a single container capacity.

• Waste containers will be labelled immediately to minimise the incidence of “unknowns”.

• Incompatible waste materials will be segregated. 3.5 Packaging Waste It is not anticipated that a significant quantity of packaging materials will be used and handled by the BioDiesel plant. Notwithstanding this, in the development and maintenance of waste contracts, GBI will preferentially contract with firms that offer recycling and recovery options for the waste streams in question. 3.6 Empty Drums Empty drums may arise from maintenance chemical storage. It will be assumed that empty drums will usually contain residues of material, unless the contents have evaporated. If drums contain residues, they will be referred to as “nominally empty” and the waste classification given will relate to the nature of the residues. For this waste, the following options for disposal will be considered:

• Return to the supplier, where the supplier will be requested to take back any empty drums.

• Drum reclamation company, where drums in good condition can be cleaned and ‘reclaimed’ by specialist companies.

• Scrap metal – drums in poor condition may only have value, in terms of recycling, as scrap metal. However, unless the scrap merchant has the facilities to properly handle residues (this will be checked) or the drums are uncontaminated, this route will be avoided.

• Waste disposal – if drums have significant residues of hazardous materials or residues of a particularly hazardous nature, a waste disposal contractor will be employed to safely dispose of them.

Nominally, empty drums will be either stored horizontally or vertically in a contained area, within the maintenance area in order to protect site drainage from any leaks. Drums will be lidded, capped or in a covered area to prevent water ingress. Drums will also be labelled to show that they are empty, however, information on possible residues will be included for proper handling by recycling and waste contractors. All wastes will be removed from site by local authority licensed waste collection agents, for disposal at permitted waste disposal facilities as discussed above. 3.7 Waste Disposal Arrangements In the case of waste generated at the GBI facility to be disposed of off-site, GBI will,

with final approval from the EPA, agree a contract with suitable and licensed waste disposal contractors for both hazardous and non-hazardous waste types. A provisional guidance list of suitable waste undertakers for the GBI facility is outlined below:

o ENVA - comprehensive chemical and biological treatment and disposal options for hazardous / non-hazardous wastes generated by all industries. The recovery and disposal of a diverse range of waste.

o Indaver Ireland– Recovery and disposal of wastes; waste management facility.

o Cork Metals – Recovery and recycling of metals. o Domestic type waste – Greenstar –recycling and materials recovery; Wexford

County Council local authority.

The contracted waste disposal company(s) will be approved by the EPA in terms of its suitability and compliance with current legislative standards when dealing with the recovery of wastes arising from the GBI facility and potential disposal at suitably licensed landfills. 4.0 WASTE HANDLING SUMMARY The whole process at GBI is designed to minimise waste generation. However, the GBI installation at Marshmeadows, New Ross will generate small quantities of both liquid and solid wastes from the process and auxiliary activities. It is only possible to make estimates at the moment in terms of the level of generation of these wastes. It should be noted that waste handling will form an intrinsic part of the EMS and will be applied across the entire BioDiesel facility, in the form of a suitable waste management plan. Good industry practice (i.e. through the application of Best Available Technology (BAT)) will be adopted for waste handling. This will include clear sign posting and labelling of all waste receptacles, auditing of waste areas and waste contractors, segregation of incompatible wastes (either through statutory designation or chemical incompatibility) and prevention of the escape of wastes from receptacles and storage areas. As part of its drive for continual improvements in environmental performance GBI will keep accurate records of all waste arisings and agreed and approved waste disposal arrangements. This information will be provided annually to the Environmental Protection Agency in the facility’s annual environmental (AER) report.
