h INTRODUCTION
The Hammond Lane Metal eo. Ltd. propose to relocate their Dublin Fragmentation Plant and Scrap Depot from Sir John Rogersons Quay to Pigeon House Road. The Hammond Lane Metal Co. Ltd. has a Fragmentation Plant in Cork as well as other Depots for collection of scrap in Cork, Limerick, Athlone and Galway.
Preliminary discussions on this project with the Dublin Port and Docks Board, Dublin Corporation and the Eastern Health Board (Environmental Section) resulted in a request that an Environmental Impact Statement (E.I.S.) be submitted.
The Hammond Lane Metal eo. Ltd. requested that Mr. Barry Kelleher and Mr. Eanna O'Kelly, Consulting Engineers prepare and submit the E.I.S. for them. Mr. B. Kelleher is the Consulting Engineer appointed by The Hammond Lane Metal Co. Ltd. for this project and they have also retained the services of Mr. O'Kelly of Quaestor Analytic Ltd. to advise on a particular aspect namely Noise Emissions. It should be noted that both of these Consultants were involved in the recently built ( 1991) Cork Fragmentation Plant.
Other information on this study has been obtained from The Hammond Lane Metal Co. Ltd. and M/S. Lindemann (the proposed shredder plant suppliers) and The Hammond Lane Metal eo. Ltd.'s associate Company in the U.K. M/S. Mayer Parry Recycling.
A visit was made to see a new Lindemann Fragmentation Plant operating in Glasgow, Scotland earlier this year. The Lindemann equipment is manufactured to the latest EC Specifications and meets all current safety standards.
Information on existing services roads etc. has been obtained from the Dublin Port and Docks Board, and the Consulting Engineer for the previous occupiers of the site.

~ NON TECHNICAL SUMMARY
The Hammond Lane Metal eo. Ltd. proposal is to relocate the Dublin Fragmentation Plant and Scrap Depot in Pigeon House Road. This Plant is in addition to a similar one in Cork as well as existing Depots for collection of scrap metal in Cork, Limerick, Athlone and Galway.
The new Plant will product 50000 tonnes of high grade fragmented scrap per year. It can deal with truck loads of car bodies, domestic applicances, farm machinery etc.
The scrap is fed into the shredder where it is reduced in size. The changed scrap is reduced to small pieces by a rotor. It is then conveyed via a draw off vibrating conveyor and a following belt conveyor to the separating drum and a magnetic drum where the high guali ty fragmented scrap is separated from the nonferrous metals and waste materials. These 3 11 streams" are deposited in different compartments.
The fragmented scrap is exported for use in a steel mill as a raw material, the non ferrous metals are collected, packed on site and exported onward for further processing and the 'i1vaste materials are taken off site to an approved Local Authority landfill site.
Some steel scrap sections are too large to be processed in the Shredder. These are therefore reduced in size by the Shears. The existing BOO tonne Lindemann Shears will be moved from Sir John Rogersons Quay to the new site. This is a type of guillotine shears which works on the heavier steel sections not able to be processed in the Fragmentation Plant. The resultant steel scrap like the fragmented scrap is sent to a steel mill as a raw material.
As well as Scrap being produced by the Fragmentation Plant and Shears there will also be an area where oversized scrap will be cut to size using Oxygen and Propane cutting equipment. M.C. P. (Multi Cylinder Pack) of Oxygen and Propane will be used and all equipment will be the most modern available.
Space is therefore needed on site for raw material storage, the Plant itself, finished fragmented scrap storage, scrap from the shears, a non ferrous metals building, weighbridges, offices, workshop, ESB building, Car Parking and room for traffic circulation.
Some of these facilities i.e. Offices, Weighbridges, a building suitable for Non Ferrous Metals (existing garage) are already on site together with some services from the previous site user Coal Distributors Ltd.

~ PROJECT DESCRIPTION
THE PROJECT
4.1 HISTORY OF THE COMPA_WY
The Company was founded under the banner of The Hammond Lane Foundary eo. Ltd. in 1898. This means that The Hammond Lane Metal eo. Ltd. will be celebrating 100 years in business in 3 years time. The present Company, The Hammond Lane Metal Co. Ltd. was incorporated in 1936 operating in the Dublin area. Branches were established in Cork in 1954, Athlone in 1966, Limerick in 1975 and a further branch in Sir John Rogersons Quay in Dublin in 1977.
The Company presently have a Fragmentation Plant in Sir John Rogersons Quay, Dublin and Ringaskiddy, Cork. A total of approx. 100000 tonnes representing about 90% of the total scrap arising in the Country is processed annually by The Hammond Lane Metal eo. Ltd.
The Companys present Directors are Mr. D. H. Frame (Managing Director), F.P. Donnelly, J.A. Roberts, P. Keogh and M.W. Taylor.
The Company is engaged in the processing of Ferrous and Non Ferrous Metals for supplying to steel mills, foundries and smelters both here in Ireland and abroad.
The main product of the Company is steel scrap for steel mills. The scrap is collected or delivered, sorted, sheared and/or fragmented to strict specifications for the mills. The finished highgrade scrap is either exported or sold to Irish Steel Ltd.
The Hammond Lane Metal Company Ltd. have 2 main reasons for moving. These are:-
1. The proposed relocation of the Dublin Fragmentation Plant from Sir John Rogersons Quay is in accordance with Dublin Corporation's objectives to rejuvenate Sir John Rogersons Quay for residental purposes.
2. Because of the necessity to upgrade the present Processing Plant.
In relocating the Plant to the Pigeon House Road site it is proposed to purchase a new Fragmentation Plant. The Pigeon House Road site was previously used by Coal Distributors for a massive coal handling, bagging, distribution operation and is the site zoned for General Industrial use.
The existence of The Hammond Lane Metal eo. Depots throughout the country ensures that scrap cars etc. are collected from the countryside. It is therefore, environmentally a very desirable facility to have available in this Country.

4o2 DESCRIPTION OF PROJECT
The Hammond Lane Metal eo. Ltd. intend to purchase a new shredder for the Pigeon House Road Sl~e. It is likely that is will be a Lindemann - Zerdirator (a particular type of Shredder) . This would be an upgrade on the present Shredder, also a Lindemann one, on the Sir John Rogersons Quay site.
The new Plant will produce 50000 tonnes of high grade finished scrap per year. The main source of supply will be:-
1. Car bodies from Dismantlers, Breakers etc.
2. The Hammond Lane Metal Co. Ltd.'s Athlone Depot.
3. Approx. 30% of the feedstock would be light iron suitable for the Shredder would come from Commercial and Domestic Suppliers.
The new Plant can deal with lorry loads of car bodies, domestic applicances 1 farm machinery etc. It should be noted that domestic fridges delivered to the site will have had the C.F.C.'s removed prior to delivery.
Car wiring is processed and separated out in the shredding operation.
The plant can process raw materials up to 6mm thick. The shredding machine will be powered by a 2000 HP motor and can process approx. 65000 tonnes per - of scrap material.
It is proposed to have an electric tor on the new site whereas there is a diesel one on the Sir John Rogersons Quay site. It should be noted that the electric motor is much more desirable environmentally both from the point of view of noise and emissions.
The proposed new Plant is shown on Diagrams in Appendix.
The raw material is fed into the shredding mill where the motor reduces the metals in size. The separating drum and the magnetic drum separates the high quality fragmented scrap from the nonferrous metals and from the dirt, dust and light fractions. The latter portion is removed off site daily to an approved Local Authority landfill site.
The Hammond Lane Metal eo. Ltd. presently supply Irish Steel with high quality fragmented scrap from their Ringaskiddy, facility and it is expected that all of high quality scrap the Pigeon House Road site be exported to the U.K. and Continent of Europe.

4.3 SITE SELECTION
The Hammond Lane Metal eo. Ltd. required a site of approx. 4.3 acres in area for this project. It is desirable that the site selected be zoned for General Industry, with good access, water availability and other services on site.
It was also desirable though not essential that the site would be near the present one as the present head orr 1ce on Sir John Rogersons Quay would be used in the short term until the nev-1 Plant is up and running.
The Hammond Lane Metal Co. Ltd. had indicated to the Dublin Port and Docks Board that they would be interested in relocating if a sui table site was available and so this eventuated when Coal Distributors Ltd. vacated the Pigeon House Road site.
The site is in an area where the Dublin Port and Docks Board intend to develop their container operation, is bounded on the west by Industrial sites and the old ESB generating station, on the south by more Industrial Sites and on the east by the Dublin Corporation Sewage Treatment Works.
If The Hammond Lane Metal Co. Ltd. are not able to sell the Scrap to Irish Steel Ltd. for any reason it can be exported to other Steel Mills in the E.C. and with this site there is a first class loading facility available.
The nearest houses are approx. 800 metres away on the southern link road and opposite Irish Glass Bottle Ltd.
The site has a quay on the north side where boats of up to 30000 tonnes capacity can berth.
The site is owned and controlled by Dublin Port and Docks Board. We have had a meeting with them outlining the proposal for this project and they are satisfied with same. All they have asked is to be kept informed as the project progresses.
The site is therefore ideal for the proposed use.

4o4 SITE LAYOUT
Entrance to this site is off a side road from the Pigeon House Road - see drawings in Appendix. The entrance will be shared with Irish Cement Ltd.
Inside the entrance will be - on the north east corner - an ESB 38 KV Station with car parking adjacent. The truck traffic entering comes into a 18m - 60 tonne capacity weighbridge. The traffic circulates in an clockwise direction and exits over another 18m - 60 tonne weighbridge.
The offices and also the weighbridge and weighbridges themselves are already there. However owing to the reduction in scale of operations on site from both the traffic and personnel employed point of view approx. 50% of the present office space only is necessary.
A substantial portion of the site is required to give a satisfactory circulation/turning area for delivery of raw materials. These will be deposited onto a raw scrap stockpile and a crane of approx. 20 tonnes capacity will load the scrap onto the conveyor to the shredder (The fragmentation process is described in 4.6 Processing Technology).
The shredder itself, 2000 HP electric motor, major plant support loads, shears etc. will all be supported on piles and as the site was originally filled behind the quay wall. The Shredder Plant for associated end products will be located on the North-Eastern corner of the site. It will have an adjoining building with transformers, switchgear and hydraulic power pack.
Anit-vibration springs and a damper system will be incorporated under the Shredder to isolate the foundations, from most of the vibrations produced at the shredder due to the shredding process. This will minimise any vibrations that could be transferred to surrounding areas.
Noise reduction/sound absorbing wall panels will be located as near as possible to the main noise source, the Shredder itself. The foundation for these wall panels will be isolated from the Shredder foundations.
All structural steelwork supporting the Plant will be painted in a goosening grey colour to the satisfaction of the Planning Authority, Dublin Corporation.
The eastern end of the site is where the high quality fragmented scrap is stored and removed off site.
The non-ferrous metals building is presently a garage and will be refurbished as necessary. Adjoining diesel storage and pumps will be used for truck refilling as necessary.

There will be a workshop approx. 20 metres X 10 metres X 5 metres to the eaves.
The Shears, with adjoining transformer and switchgear, will be located on the southern side of the site.
There will be a screen wall constructed of 215mm concrete block with piers and capped on the southern boundary of the site between the non ferrous metals building and the workshop and also on the south side of the shears.
Use will be made as far as possible of the existing surface water drains, foul sewage direct to piping pumping, water supply piping, electricity and phone lines.

4.5 DESCRIPTION AND WORKING METHOD OF MAIN PLANT
A new shredder - probably a Lindemann Zerdirator - Plant will be purchased.
The follovling is a Plant. (Please note Lindemann) .
Feeding
description and working method of such a that this description was supplied by M/S.
Car bodies or other mixed scrap are charged onto the inclined feeding chute of the Zerdirator by means of a crane or a hydraulic grab. By its own weight, the material glides on to a pair of feed rollers arranged at the lower end of the chute right in front of the Zerdirator opening.
The rollers seize the scrap or the car bodies, squeezing them flat and pushing them onto the Zerdirator at a controlled feeding rate.
Feed roller motions are automatically switched on and off by electrical instruments in order to maintain a constant load on the main motor, thus also avoiding overcharging of the Zerdirator. Provisions have been made for manual operation and reverse movement of the rollers when intricate scrap pieces are to be handled.
The upper feed roller is mounted in a frame in such a way that it is allo'i'Jed to swing up and down so that it is capable of adjusting itself to the various sizes of scrap pieces. Normally, the weight of the roller itself is sufficient for the squeezing process; if not, the machine opera tor can switch on two hydraulic cylinders by actuating a control lever. The upper roller may also be lifted by these cylinders in order to permit high vehicles to be brought between the rollers.
Framnentizinq
The rotor's sense of direction corresponds to the material feeding direction. The charged scrap is torn off at the anvil edge. Those scrap pieces which are small enough leave the Zerdirator through the grid openings of either bottom grid basket or top grid plate.
At a second anvil bar underneath the baffle plate such scrap pieces, which are too big to pass through the grid, 'are further reduced in size. By going through this tearing and bouncing process, the scrap pieces are reduced in size and compressed until they can pass through the grid openings. Coarse pieces which cannot be shredded,· are eiected through a hydraulically operated ejection flap, by-passing the grids, without interrupting the production process.

After having passed the grid openings, the shredded scrap pieces are thrown back at the walls of a pivot hood and are carried to the exit opening through a collecting funnel. Simultaneously, any flying, non-metallic dust is carried off by the strong air stream of the connected dedusting equipment.
Separating
After leaving the Zerdirator, the material is conveyed via a draw-off vibrating conveyor and a following belt conveyor to the separating drum.
In the separating drum the shredded non-ferrous metals and the steel scrap are separated from adhering unholstery fluffs and other flying non-metallic material.
The material separated by mechanical action is sucked off by the attached dust extractor in opposite direction to the scrap flow.
The cleaned non-ferrous metal and steel scrap is then steadily fed into the magnetic drum via a vibrating conveyor. The magnetizable steel scrap is picked-up from the material stream, thus non-magnetic metal or waste particles which might have been withdrawn can fall back onto the vibrating conveyor.
During transportation on the drum surface in the magnetic area, the attracted steel parts move due to the changing polarity of the magnetic field on the drum shell. By this "shaking effect", jammed non-magnetic pieces can be separated. The extracted steel scrap will subsequently, in the area of the opposite, nonmagnetic drum-half, be thrown-off onto the steel sorting belt.
At the steel sorting belt parts with ferrous adherences, e.g. copper coils with ferrous core or rubber parts with ferrous enclosures (parts of tyres with steel inserts) are manually picked out. From the steel sorting belt the clean ferrous scrap is loaded direct onto the stockpile via the following slewable steel discharge belt.
The non-magnetic materials drop onto the non-ferrous metal sorting belt underneath the magnetic drum where the sizeable nonferrous metal parts are manually picked out.
The remaining material stream is conveyed into the storage bins.
Zerdirator Dust Extraction
The dust extracting equipment operates on a two-stage separation system. In the first stage, dust-laden air is sucked off and cleaned from coarse dust by centrifugal separation. The dry, separated material is continuously evacuated by a rotary air lock on to a belt conveyor, and led into a storage bin.
In the second stage, the cleaned air enters the VENTURI-wet

scrubber.
The VENTURI equipment consists of four sections: Venturi head, Venturi neck, diffuser and separator. In the convergent part of the Venturi head the cleaned air stream is accelerated and reaches its maximum speed in the Venturi neck. Water is fed in and is atomized into smallest droplets due to the incoming air stream, thus offering a large deposition area for finest dust particles. In the diffuser, speed energy is partly transformed into pressure energy, and the small droplets are condensed into bigger ones. In the adjacent separator, the water containing fine dust particles is separated by mass moment of inertia and centrifugal forces. The clean air is discharged by the fan through a connection piping. Through the conical water collector, the water is fed into the water preparation plant for purification. While the purified water is fed back into the Venturi through pumps, solid materials are removed by means of a scraper conveyor onto the mud conveyor and then to a storage bin.
Separating Drum Dust Extraction
The dust extraction operates with circulating air. The dustladen crude gas sucked off at the separating drum is pre-cleaned from coarse dust and waste by centrifugal force separation in a cyclone.
The separated dry material is continuously evacuated by a rotary air lock onto a belt conveyor. A partial stream of the precleaned air is led to the Venturi-scrubber of the Zerdirator dust extraction via a connected air pipeline for further cleaning.
The main volume of the precleaned air is led back into the separating drum via a circulation air fan.
The waste material from both Zerdirator dust extraction and separating drum dust extraction is conveyed into containers via several belt conveyors.
Painting
In general, the painting of Lindemann machines/plants consists of one prime coat and one top coat.

A stockpile of raw material scrap would be retained on site.
Scrap would be continuously fed 1 using a 25 tonne capacity crane to the feed conveyor and there onto the shredder as previously described.
The finished frag. scrap would be stored on site and then loaded on to a boat at the quayside.
The dirt would be removed off site on a daily basis to an approved Local Authority landfill site.
The non ferrous metals would be taken to the non ferrous metals building and packed and exportedo
The overall extra traffic generated by this project would be 150/200 trucks movements per week.
Additiional regular traffic to the Plant would be for suppliers with maintenancejreplacement equipment and employee travel.
The Plant will be run on a single shift operation Monday to Friday 7.a.m. to 7.p.m. and Saturday 7.a.m. to l.p.m. The Hammond Lane Metal eo. Ltd. will avail of the maximum demand tariff on this Plants power supply as offered by the ESB during the months of November, December, January and February. This means that the Plant will cease production during these 4 months at 4.45 p.m. each day.

~ ENVIRONMENTAL EMISSIONS ARISING FROM PROCESS
5.1 NOISE
The process of metal fragmentation is inherently noisy. It lS not practical to reduce the noise emission from the plant by totally enclosing the plant in a building. The plant layout as proposed has been advised by the plant manufacturers as being the optimum for this particular site. Some noise reduction can be achieved by acoustically screening the Shredder Mill on the southern side.
Noise measurements and analysis were carried out by Quaestor at the existing fragmentation plant operated by Hammond Lane Metal Company at Ringaskiddy. This plant, rather than the one at Pigeon House Road, is very similar to the proposed plant, with the exception that the separator at the proposed plant will be a drum type. This will be acoustically damped and screened. A vibratory type separator is used at Ringaskiddy. This is a noisier type of unit.
The results of the survey at Ringaskiddy show that the expected noise level at 135 metres distance in line of sight from the sh:edder would be. an LAeg 1 h~ur level of 69dBA. Extrapolating thls data would glve the ~~ollowlng levels.
(a) Entrance to site (b) Southern Boundary of site (c) Coastguard Cottages
LAeg 1 hour 65 ' 70 50
This assumes acoustic screening to the south of the Shredder Mill and acoustic treatment of the drum separator. It takes account of sound attenuation due to distance only, and in the case of the Coastguard Cottages, additional screening by intervening buildings and storage containers of about 4 to 5 dBA.
The location of the acoustic screening is shown on site layout drawing. The screening should consist of impervious sheeting of surface density not less than 20kgjcubic metre. The mineral wool should be physically protected by perforate metal sheeting with at least 25% open area. The impervious metal sheeting for screening can typically be preformed plastic coated metal cladding of thickness 0. 8mm. The bottom 3 metres of the screening will be 200mm precast or reinforced concrete. The acoustic screening will be 10 metres high (above ground).

The road gulleys on the site have sumps incorporated and there will also be 2 no. sedmentation chambers on the outlet lines of the surface water drains. These will ensure that no extraneous metals from The Hammond Lane Metal Co. Ltd. site will transfer to the outfall from sections of the surface water drains.

5.4 WASTE
The waste arising from this project is the dust and dirt arising from the process. This has been referred to earlier - see 4.5 etc.
On a yearly throughput of 65000 tonnes of raw material scrap the quantity of such waste will be approx. 10000 tonnes per annum.
This is stored temporarily on site in a 3 sided open concrete bin and is removed from site on a daily basis to an approved Local Authority landfill site.
The waste produced is non-toxic.

6.THE EXISTING ENviRONMENT
6.1 SITE DESCRIPTION AND PRESENT USE
The proposed site is part of land owned by the Dublin Port and Docks Board and is leased from the new lessees of the whole, larger, site who are Irish Cement Ltd.
The previous occupier of the vlhole site were Coal Distributers Ltd. who vacated the site probably following a downturn in bituminous coal imports. As far as I am aware they occupied the site for approx. 20 years and carried on a very large coal handling, bagging operation with a large number of people employed.
The existing site therefore contains, at present, a number of buildings i.e. Offices, ESB Rooms, Garage, Weighbridges and Services i.e. Foul Drainage, Surface Water Drainage, Electrical Cables, Water Pumping, Telephone Cables.
The site was originally reclaimed and filled and it will therefore be necessary to have piled foundations for any very heavy loads.
The site has recently been vacated by CDL and lS zoned for General Industrial use.

6o2 ROADS AND TRAFFIC
Access to the site is via the roundabout at the junction of the Pigeon House Road and Sean Moore Road then along the South Bank Road to Whitebank Road and along the Pigeon House Road again for a short distance - see Site Location Plan in Appendix.
The Dublin Port and Docks Board is actively pursuing provision of improved road access to the Port and requires an effective local road system linked to the National Arterial Road Network.

6.3 NOISE BASELINE
The existing ambient noise ~PJas measured at the site and at the nearest houses, which are the Coastguard Cottages located approximately 800 metres from the Shredder Mill. Measurements were made of the following hourly parameters.
LAeq - the equivalent continuous noise level in dBA
LA10 ,LAgo - the noise level equalled or exceeded for 10% and 90% respectively of the sample period.
The mean and standard determined for daytime, 22.00 to 07.00 hr.
deviation of 0 7 . 0 0 to 2 2 . 0 0
these parameters was hr. and for nighttime
The details and results of these measurements are shown in tabular and graphical form in Appendix.
The mean daytime values at the measuring locations were as follows:-
LAeq, 1 hour LA90, 1 hour
Coastguard Cottages 64 50
On site 56 50
Additional short term measurements, over 20 minute intervals, were also carried out at houses along Pigeon House Road and at Lucas Road and Clare Kyle Road. These results are also shown in Appendix.

~ IMPACT OF THIS EMPLOYMENT
7.1 DISPOSAL OF UNWANTED SCRAP VEHICLES
The Hammond Lane Metal eo. Ltd. accepts all unwanted scrap vehicles at its Depots throughout the country. Presently approx. 83000 cars per annum are removed from Irish roads per year.
The Hammond Lane Metal eo. Ltd. offers a service to Local Authorities to collect abandoned cars. This service is quick and efficient and is done with the full approval of the Gardai.
The Hammond Lane Metal eo. Ltd. offer their Multilift Container Services to structural steel fabrication Companies, Engineering shops, and steel stock holders and manufacturers of all items in ferrous and non ferrous metals. This service is also available to demolition firms.
The Hammond Lane Metal Co. Ltd. Authority Landfill sites where on site and the landfill site cars, household appliances etc. is first removed before being Plant.
The Hammond Lane Metal Co. Ltd. hire Companies in the Country.

The fact that these in the past have been abandoned at the side of the road, sometimes in scenic locations, and sometimes on main road routes has given a very bad impression to vi si tors and (potential) visiting industrialists and, indeed, is something that most Irish people would like to see stopped.
The fact that there will be 2 plants i.e this one and the one in Ringaskiddy, Cork available for recycling unwanted scrap vehicles, domestic applicances, farm machinery etc. is a very significant asset to the country.

7o2 EMPLOYMENT
The Hammond Lane Metal Co. Ltd. Fragmentation Plant will employ 25 people at the Pigeon House Road site.
Short term it is not expected to have any effect on local employment as staff will be transferred from the nearby Sir John Rogersons Quay site.
The construction of the Fragmentation Plant on the new site will provide employment for a number of people and it is expected that contracts will be placed \•li th local (Dublin) Contractors ~;...rhere possible.
The provision of goods and services to the Plant will provide additional work as at Sir John Rogersons Quay at present.
This project will be a substantial user of electricity and the ESB will benefit greatly from this.
The export of some 100,000 tonnes, total, of all types of scrap will benefit Dublin Port and Docks Board.

7a3 NOISE
During the daytime the mean value of the existing LAeq outside the Coastguard Cottages is in excess of 60dBA. The· expected contribution from the proposed development is LAeg of 50 dBA. This would not increase the existing noise level. The same applies to houses at Lucas Road and at Pigeon House Road. The houses at Clare Kyle Road would be substantially screeded from the proposed development with the result that the contribution from the proposed plant would be in the order of L~eq of 40 dBA. This would not increase the existing noise level ln this area. Consequently this noise impact on any of the nearest houses would be negligible.

7.4 ROADS AND TRAFFIC
When the operation on this site commences The Hammond Lane Metal Co. Ltd. intend to ship all our ferrous scrap both to Irish Steel Ltd., Cork and to other E.C. Countries.
While this is what is envisaged at present, this could change as some scrap could be delivered to Irish Steel Ltd. Cork by road rail system.
This usually means scrap going in containers from the new off Pigeon House Road across the Toll Bridge direct to Freight section of Iarnrod Eireann at North Wall, Dublin.
We would expect to have 150/200 truck movements per week.
site the
While this development is a modern recycling Plant The Hammond Lane Metal eo. Ltd. still do get in the odd loads of scrap by horse and cart.
The movement of traffic would be far less than movement of traffic which was generated by the previous occupier.
The present road capacity is very much less than its design capacity. Therefore this project would only have a slight increase in the overall level of traffic and the road system would be more than able to cope with same.
