Question: Is the proposed development safe and has a safety case been submitted?
A Preliminary Risk Assessment for a Proposed LNG Terminal at Amlwch prepared by Advantica for Canatxx LNG Ltd has been submitted to Anglesey County Council as part of their Planning Application.
Seven different release scenarios have been identified in this assessment. This includes Ship Spill and Ship Tank Spill with failure frequencies and individual risks discussed.
This issue is addressed in Volume 2 Appendix L of the Environmental Statement.
Canatxx LNG Ltd recognises the successful safety record of Octel and Great Lakes achieved by a well-trained and highly skilled local work force. It is Canatxx’s intention to build on this record by recruiting and training local people to operate the site safely and successfully.
In addition to the requirements of planning control there is an extensive regime of legislation, administered by the Health & Safety Executive and other agencies, with which Canatxx will have to comply. The processes associated with these regimes will follow the determination of the planning application.
Question: Why is this regasification so far away from the NTS system and not build nearer to Nateby, near Preston, Lancashire?
There is no other location in Liverpool Bay which can offer a comparable and sufficient depth of water within 3km of the coastline. Canatxx LNG Ltd has considered the feasibility of a mooring and discharge facility in deeper water elsewhere in Liverpool Bay.
However, in order to achieve comparable conditions to those available at Amlwch, it would be necessary to locate such a mooring and discharge facility at a substantial distance, approximately 24km, from the coast of Liverpool Bay.
The technologies required for the operation of such a facility are insufficiently advanced for them to be contemplated in the current decade. The cost of providing the cryogenic pipelines would have been prohibitive.
Overcoming the hydraulics problems caused by the required length of the pipeline would also have been prohibitively expensive.
This issue is addressed in Volume 1 2.8.2 of the Environmental Statement.
Question: How much real local employment will be provided during construction and operation?
As noted above, Canatxx LNG Ltd recognises the successful safety record of the Octel and formerly Great Lakes site, managed by a well trained and highly skilled local work force.
Canatxx acknowledges the work skills available on Anglesey and will be recruiting and training local people to operate the LNG regasification facility. It is anticipated that over 60 local people will be employed when the facility is operational.
Approximately one third of the workforce would work on days and two thirds would work on shift.
This issue is addressed in Volume 2 2.7.5 of the Environmental Statement
Question: Is full site clearance included in the proposal when the operation is decommissioned?
Upon the permanent cessation of the Scheme, a programme for the decommissioning and restoration of the site and platform will be submitted to the Anglesey County Council and other appropriate Authorities for approval in writing.
The restoration would include the removal of all process plant, pipework, storage vessels from the land based site and the removal of the platform structure and supporting piles. Sub-sea pipelines would not be removed.
This issue is addressed in Volume 2 2.4.52 of the Environmental Statement.
Question: How much impact will there be to the local fishing industry and recreational use of the local waters?
It should be noted that the assessment of economic impacts as a result of the Scheme is outside the scope of the Environmental Statement.
Anglesey County Council has confirmed during consultations on the Scoping Report that they would commission a separate Economic Impact Assessment.
For further Information, please see the Environmental Statement Appendix F ‘An Assessment of Potential Fishery-Related Effects of Site Development’ by Stephen J Lockwood, Coastal Fisheries Conservation & Management, Colwyn Bay.
Question: If tugs are to be used what impact will this have on the current users of the port facilities?
Canatxx LNG Ltd proposes to use three tugs to operate safely the discharging of LNG at the jetty head. Tugs could be sited in Amlwch Port, Holyhead Port or on Merseyside.
Discussions need to take place with all the interested parties to establish if Canatxx tugs could be accommodated in Amlwch Port.
Question: The operating history of the Shell facility demonstrated that the positioning of the mooring previously used did not support full operational use due to the effects of the weather and the sea conditions.
How will LNG tankers be discharged safely?
The Shell facility moored tankers around a weather vaining buoy built by Single Buoy Mooring (SBM) Ltd. 30 years on SBM have proposed the design for a fixed platform at approximately the same location as the previous buoy.
Tankers will be docked against the SBM soft quay docking system. They will be assisted by dedicated tugs. The soft quay consists of a 3,000 metric tonnes (MT) plate which is supported from two derricks and which hangs between the ship and the platform.
The plate has rolling fenders located along its length and is located midship. There is a 30m gap between the ship and the platform when the tanker is correctly moored and the object of the soft quay is to provide for a large degree of relative movement between the ship and platform under varying wind, wave and tidal conditions without incurring damage to the ship or platform.
The SBM Ltd soft quay docking system can discharge tankers in seas of 2.5 meters of significant wave height. A meteorological study was prepared for Canatxx LNG Ltd by the Marine Science Laboratories at the University of Wales Bangor.
These data included mean and 100 year data for wave height and period, wind direction and wind speed and tide height, flow and direction.
Based on these data, SBM predict availability for LNG tankers of 98.2%, which equates to 358 days a year.
In conjunction with weather forecasting it would be possible to manage the availability window throughout the year.
The platform would not require any breakwater and would be designed to withstand/survive 100 year severe weather conditions.

Question: Does the council know what local residents and stakeholders think about the proposal?
Canatxx has undertaken a number of initiatives in order to inform the public and local and other stakeholders. They include:
- A 3 day exhibition which was attended by over 300 people
- The exhibition was featured in The Daily Post and The Anglesey Mail on the 12th July and in The Chronicle on the 13th July 2006.
- A half page full colour advertisement was placed in The Anglesey Mail newspaper on the 5th July 2006.
- Posters were distributed to local shops in the Amlwch and surrounding area.
- 2,000 invitations were distributed with the Amlwch Communities First newsletter in the week beginning 10th July 2006.
Canatxx considered that it was important to provide information to and to gather information from the public to promote understanding of what is proposed and to understand what concerns people may have.
Things learned as a result of the Exhibition gave rise to material alterations to Canatxx's original proposals and these are reflected in the planning application. Further reference can be seen in the Planning Statement Appendix 4.
Question: I understand that a recent report recommends that a facility like this is not sited near a residential area, yet this one is being proposed within yards of a residential estate and a primary school?
Canatxx is not proposing to build a gas or LNG storage facility at Amlwch. The proposal for the regasification terminal is unique because as soon as the LNG is pumped on shore it is warmed, turns into gas and sent off by pipeline to the NTS system at Nateby, near Preston, Lancashire.
At a typical regasification site the jetty will extend, into the sea, between ½ and 1 Km. At Amlwch the freestanding platform is located 3 Km offshore. The LNG is pumped ashore through a sub sea cryogenic pipeline.
Most LNG tankers carry 150,000 cubic meters of LNG. A typical regasification site is built to store four tankers of LNG, 600,000 cubic meters approximately.
In contrast at Amlwch there will be two tanks capable of storing approximately 7,000 cubic meters of LNG. These will be total containment tanks built to the highest design codes and standards. They will be built into the ground for added safety.
The process designed for Amlwch uses tried and proven technology. The equipment also has an outstanding safety record of over 30 years of LNG regasification operation.
