Ymholiad / Enquiry: Glyn Rhonwy DCO Lleoliad / Location: GLYN RHONWY, LLANBERIS, GWYNEDD.

Annwyl Syr/Madam / Dear Sir/Madam,

The Glynrhonwy (Pumped Storage) Order

Section 42 Planning Act 2008

The Infrastructure Planning (Applications: Prescribed Forms and Procedure) Regulations 2009

The Infrastructure Planning (Environmental Impact Assessment) Regulations 2009

Please find this letter as a formal response to the statutory consultation exercise made by Snowdonia Pumped Hydro Limited in pursuant to section 42 of the Planning Act 2008.

It is noted here that Gwynedd Council is also affected by way of it being the owner of land affected by the proposed development. This letter will also therefore include a consultation response under the requirements of section 44 of the Planning Act 2008.

The proposed development is to build, operate and maintain a pumped hydro-electric storage scheme at Glynrhonwy, Llanberis, Gwynedd with a generating capacity of 99.9MW. As the generation capacity of the proposed development exceeds 50MW, an application for a Development Consent Order is required under the Planning Act 2008.

Planning permission has been previously been granted in February 2014 under the Town and Country Planning Act 1990 (TCPA) by Gwynedd Council as the Local Planning Authority (ref. no. C12/1451/15/LL), for a 49.9MW pumped storage scheme at the development site.

For the avoidance of doubt, the following comments are made in relation to an application for Development Consent Order as an identified statutory consultee under the Planning Act 2008.

The following relevant representations contain an overview of the project and are given without prejudice to any further detailed representations that may be made by Gwynedd Council during the examination process. It is also noted that Gwynedd Council may seek to make further representations if supplementary information becomes available in relation to the project.

Snowdonia Pumped Hydro has submitted a preliminary/draft Environmental Statement which “presents a preliminary assessment of the likely environmental effects of the proposed development, together with a non- technical summary of this information”. A review of the draft Environmental Statement and supporting documents dated 9th February 2015 and received on 12th February 2015 has been made by relevant officers within Gwynedd Council and the following are comments received in respect of this information.

Visual Impact

It is recognised that parts of the development site are in very prominent locations within the local landscape. It is therefore understandable that the previous application contained a number of objections based on concerns regarding the impact of the development on the local landscape and its long term effects on both the natural landscape and also on the historical/industrial landscape as well. The site lies within a Landscape Character Area and the Dinorwig Landscape of Outstanding Historical Interest as a consequence of the slate quarry workings dating back to the 19th and 20th century.

The actual difference between the previously approved application and the DCO application is likely to be minimal if relevant at all. It is recognised that there will be no major or fundamental changes proposed to above ground structures or features. As a consequence, it is considered that the issue of visual impact is not likely to be greater than what was previously considered as part of the TCPA application. Previously attached conditions are considered to be relevant in terms of safeguarding the visual aspect.

Effects of Construction

As has been previously stated, the difference between the approved development and proposed DCO application is likely to be minimal. The consequence of the change in the position of the red line defining the development area from what has been approved to what is proposed needs to be given consideration as to whether the additional areas will increase the effect of the development on specific issues/land/residential properties which may not have been highlighted or given as much consideration previously due to the positioning of the red line. The actual difference in terms of the physical development of a 49.9MW scheme to a 99.9MW scheme is somewhat negligible due to the changes being in relation to having more powerful underground turbines and associated equipment.

Notwithstanding the above, clear and informed assessments must be provided within the ES with a clear methodology set out in terms of the proposal. As referred to in the current information, a Code of Construction Practice (CoCP) will be developed into a finalized site specific version at the detailed design stage, as agreed with Gwynedd Council. It is considered that the information provided to date indicates that the methodology is acceptable and the subsequent conclusions and mitigation is also acceptable. This advice is obviously given without prejudice to any further detailed representations that may be made by Gwynedd Council, it is considered that an opportunity to agree upon the final version will be achieved at a later stage.

It is recognised that the issue of traffic management and any other related traffic issues, are consistently referred to in various aspects not necessarily formal assessments such as a Traffic Management Plan. This is inevitable as this issue does cross into various aspects of the development, but as has been indicated throughout various stages. The Transportation Unit has taken the view that what will be the DCO application, is unlikely to differ from what has already been considered and agreed upon in terms of highway matters. Furthermore, agreements are required regarding various elements which affect the local highway network by way of other legislative requirements such as a s278 agreement to include an extraordinary traffic agreement. It is considered that although current details which refer to highway matters are acceptable in principle, the opportunity to provide further representations can be made at the adoption stage of agreements such as the s278.

The following comments are given by the Public Protection Unit:

x The methods set out in the noise and air draft ES are considered adequate and appropriate. We also accept that the applicant has made reference to the correct guidance and standards. The conclusions drawn at this stage are inevitably fairly broad but we offer no challenge. With regard to the proposed measure of pollution and mitigation, again we see no real problem at this stage. Please confirm code of Construction practice if you wish to obtain our views on this element. We consider this development to be one scheme, however, cumulative impact would be assessed under each Environmental aspect (noise, air quality, lighting etc). In terms of cumulative impact on local residents, there is an option of undertaking a Health impact assessment which could incorporate all these different aspects. x Statement with respect to statutory nuisance – No comment

x Noise – Draft ES chapter 12, paragraph 3.3.4 – it is stated that a period of 4 years is temporary, whilst this may be true in terms of the project’s lifetime, local residents may not consider such a period to be temporary.

Table 12-17 – highlight the different elements of works that need to be carried out at the same time if the project is to be completed within 4 years. It is also advisable that an attempt is made to show a timetable of works during the development period ( unless this is shown separately in another document ). A clearer understanding of the likely noise impact will be gained if the likely noise levels arising from the intended works is shown in terms of previously identified noise sensitive properties adjoining the site.

Paragraph 12:10:2 – reference is made to section 61 of the Control of Pollution Act 1974 in terms of controlling and managing works outside normal working hours. The authority is keen to avoid any duplication in terms of implementing noise control procedures, the use of more than one method in order to control noise has the potential of one not corresponding with the other ( relevant TCPA application conditions ). Attention is drawn to condition 25 attached to the TCPA application approval.

It is noted that due to the proposed amendment to the approved development boundary, some advisory documents contained within the existing permission are also likely to be amended such as SB4142:1997 into SB4142:2014.

x Summary of mitigation – Draft ES chapter 17 – paragraph 17.1.2 of this chapter states, “ the relevance of the planning conditions set out in the planning approval for the 49.9MW T&CPA application has also been provided to demonstrate that the principles of these conditions will be incorporated into the DCO requirements”.

If the developer is able to confirm its continued acceptance of the environmental conditions attached to the previous approval, C12/1451/11/LL, within a 4 year construction timetable, the service will have no objection to the proposed development. Although it is recognised that this may be difficult to achieve in terms of timing, the service is not aware of any reason why this cannot be achieved.

It is suggested that Quarry Battery Company Ltd provides clear reference to documents containing details as referred to above, if this has not already been done in another elsewhere.

Ecology

The following comments are given by Gwynedd Council’s Biodiversity Unit:

The new proposals are similar in nearly all respect to that which was approved for planning application ref. no. C12/1451/15/LL. The main differences are the increased turbine size and the fact that the boundary of the development has been extended to accommodate any possible changes that may occur during the works. No Significant Effects Report

We are satisfied with the No Significant Effects report and concur with its findings. As a Competent Authority for the original planning application Gwynedd Council carried out a Habitat Regulations Assessment and came to the same conclusion regarding possible impacts on Llyn Cwellyn and Afon Gwyrfai - no likely significant effects. However we do have some comments to add:

In the Executive summary dealing with in combination effects, the report states: In relation to the assessment of in-combination effects on the Natura 2000 sites, in agreement with NRW and Gwynedd Council there were no projects or plans in the vicinity of the Development.

We don’t believe this is line with the requirements of the Habitat Regulations. The possible plans or projects which could have an in combination effect on a Natura 2000 site need not necessarily be in the vicinity of the development. They only need to have potential to, or have had an impact on the European site. Many of the sites which are considered are very large so in theory a development not in the vicinity of the development could have an impact. For instance a plan or project in East Anglesey could have an in combination effect with the development on the Menai Straits Conwy Bay SAC with the development. This is hypothetical and in reality we believe there is only one development which could have an in- combination effect on a European Site, and that is the Caernarfon and Bontnewydd bypass. This development is moving on apace after many years of planning and consultation The route of the new road crosses over The Gwyrfai River (SAC) downstream of Bontnewydd. Construction work is scheduled to run from December 2016 to September 2018. It is quite possible that both developments could have construction phases running concurrently. Nant y Betws is the only pathway for the development to have an impact on the Gwyrfai, and because of the mitigation measures proposed any impact on the Afon Gwyrfai it unlikely. It is therefore still unlikely that there would be an in- combination effect. However the issue should be addressed fully in the ES for completeness.

Draft Environmental Statement

We agree that the methodology is adequate and appropriate and the Mitigation is reasonable. We have few comments to make as most of this work has already been assessed during the previous application. Very little has changed apart form the results of more recent surveys which are satisfactory. We understand that there are concerns that the new larger turbine may affect the water temperature which may be reaching Llyn Padarn and so effect the SSI features. We understand that NRW have raised this specific issues in their comments and that you are in discussions with them.

ES Cumulative Impact

We are satisfied with the content of the chapter but note that the proposed Caernarfon/Bontnewydd Bypass is not mentioned. See above.

Extended boundary

Further ecological features may be impacted upon within the extended boundary (order limit), as opposed to the lesser area which has gained planning permission. Therefore, we request that any area within this extension be subject to further survey, and any additional information submitted within the final Environmental Statement. Birds

We believe breeding peregrines used a different nest site in 2014 and moved last year to quarry number 5 having previously nested in quarry 4. This year, ravens appeared to have taken over the nest site in quarry 5 and were busy nest building on 10/03/15. This year, the peregrines appear to be nesting again in quarry 4. It would be prudent to assess the breeding location of peregrines annually as they can alternate between several local nest sites yearly. This should be included in the ES.

The boundary of the development has been extended from the original planning application boundary. Any additional areas inside the order boundary should be surveyed. Any further surveys should target yellowhammers in particular and an assessment made of the impact on them and included in section 6.8.102.

We note that no yellowhammer were discovered during any of the bird surveys. The area is known locally as a stronghold for the species which is red listed UK BAP priority species and included in NERC section 42 list. Singing males were heard just north and south of the order limit along the Clegir road on 10/03/2015.

Transportation/Highway issues

Full consideration and input into acceptable measures and likely effects on the local highway network has previously been given as part of the determination of the application considered under the TCPA. It is not considered that the proposed increase in output and additional number of turbines as a result of the DCO application will lead to a significant increase in construction traffic to and from the site. In order to safeguard the local highway network, it is advised that an ‘extraordinary traffic agreement’ is agreed upon. Information regarding Traffic and Transport ( to include a Construction Method Statement ) should be updated to reflect the increase in construction operations if any are proposed.

Socio economic impacts

The development will be a major economic generator during the construction phase whilst also providing long term opportunities for the area. The long term viability of the site will be enhanced by the proposal.

Section 44 Planning Act 2008

It is hereby stated that Gwynedd Council has an interest in land affected by the proposed application and/or may be affected by the proposed development. In terms of land within the Council’s ownership, this matter has and is currently being discussed between officers of the Council’s Estates service and the developer with an agreement in principle regarding the details of future arrangements. The final agreement will be in the form of a formal lease between Gwynedd Council and the developer. It is understood that a draft version is already in place with a view to formally agree its contents at a later date.

It is confirmed that the information provided to date is acceptable, however it is again affirmed that these representations are given without prejudice to any further detailed representations that may be made by Gwynedd Council during the examination process. It is also noted that Gwynedd Council may seek to make further representations if supplementary information becomes available in relation to the project or if amendments are proposed or required in relation to the project.

I’m confident that the above has responded to the relevant matters as raised, if you require any additional information or clarification, do not hesitate to contact Gwynedd Council’s Planning Service.

From: Gruffudd Glyn Llewelyn (Rh-CTGC) [[email protected]] Sent: 27 May 2015 09:58 To: Anderson, Catherine Subject: RE: Glyn Rhonwy - Approval of Socio-economic scope

Bore da/Good morning

Apologies for not responding sooner to your e-mail, i hope this has not caused you any inconvenience.

It is agreed that baseline surveys should be updated to reflect the current situation, although it is not certain to what degree if at all, that changes have occurred since the details provided for the TCPA scheme. Any baseline surveys should also reflect ( if applicable ) the changes that are now proposed to the development area as defined by the amended red line.

Reference should be made within relevant sections to the recently approved Glynrhonwy Caravan site, the development of this site has already commenced, whether it is entirely relevant in terms of bed availability is doubtful, however, it is assumed that it should be referred to in order to reflect current activities.

I hope that the recent public consultation events provided you with a broad but fair reflection of local people’s views regarding the proposed development, it is apparent that a group has been set up due to concerns regarding the impact of developments on Llyn Padarn and surrounding areas, i believe that it is not only in response to proposals at Glynrhonwy but to various other proposals as well.

The Local Planning Authority continues to work from the Gwynedd Unitary Development Plan in terms of adopted policies, the Anglesey and Gwynedd Joint Local Development Plan will eventually supercede the UDP, but it is currently unadopted. I would advise you to liaise with the Joint Planning Policy Unit for updates regarding this matter if it is deemed to be necessary.

If you require a further detailed response, do not hesitate to contact me.

______From: Anderson, Catherine Sent: 21 April 2015 16:49 To: Gruffudd Glyn Llewelyn (Rh-CTGC) Cc: Collins, Sophie Subject: Glyn Rhonwy - Approval of Socio-economic scope

Afternoon Glyn

Hope you are well. In response to our proposed update to the socio-economic chapter for the EIA for the Glyn Rhonwy DCO application, we made the following comment within the 2015 Scoping Report:

1 It is considered that the bed availability study is still valid within the 2012 ES but that the chapter will be updated for any recent recreation activities or events in the area. It is not proposed to undertake the bed availability questionnaire but use other sources of information such as the STEAM reports. It is recognized that there will be applications made for the temporary (construction) and permanent (operation) diversions of PRoW at Q1.

The Secretary of State had the following comment within Section 3.80 of Scoping Opinion:

The Secretary of State notes that the description of baseline conditions will be updated to take into account any changes since the 2012 ES for the TCPA scheme was produced. It is noted that no additional primary data collection is proposed. The applicant should seek agreement on this approach from the relevant planning authority.

Therefore we are requesting confirmation as the Local Planning Authority that you are happy with the approach taken to update the socio-economic assessment to ensure that it fit for the DCO application. The Final ES chapter has now been amended to incorporate the proposed changes described above, and also the following additional updates to reflect comments received during recent consultation exercises:

1. Relevant Planning Policy updates; 2. Review of the study area; 3. Baseline updates where relevant and publicly available, particularly in relation to bedspaces, where baseline information has been obtained from the Welsh Government bedstock surveys; 4. Construction impacts on tourism have been updated to include an assessment of impacts on accommodation from the construction workforce and changes in Order Limits and Rochdale Envelope; 5. Operation impacts on the local economy have been updated to include in a number of additional benefits on the economy due to increased workforce size (up to 5 additional workers) and the increased capacity of the Development; 6. Comments received from relevant bodies and s42 consultees have been considered, with additional detail added to the chapter in relation to impact upon PRoW and recreational receptors such as users of the PRoW network around Cefn Du and the Lagoons of Llyn Padarn; and 7. A review of PRoW has been undertaken, with an up to date record of current PRoWs to be gained in consultation with the Gwynedd Council PRoW Officer, and amendments to the diversions and closures to PRoWs required during construction and operation of the Development.

We hope that these updates to the scope of the socio-economic assessment are satisfactory. Please confirm if this is the case or respond with any queries you may have.

Many thanks Catherine

I have read the attached report. As long as all the recommendations outlined in Sections 9.1 and 9.2 of the report are followed with regard to future ground investigations and works we have no objections.

Any further investigations will have to assess the contamination risks of the chemical residues left behind from the past disposal activities of ordnance at the site.

3 Dear Catherine,

Thank you for consulting us on the "Sitesafe UXO Desk Study" by Zetica, dated 13 February 2015, Report Reference P3300-12-R1-B, received 26th March.

The report explains the methodology for checking for the presence of exploded and unexploded ordnance in advance, or sometimes as part of, the intrusive land contamination ground investigation.

We welcome the report and the proposed investigation. However, we cannot comment on the adequacy or appropriateness of the proposed survey in terms of finding ordnance. This is not within our remit. This possibly falls within the remit of the Health and Safety Executive. We would also advise that Gwynedd Council's Environmental Health officer is consulted.

We note that where material, which is suspected of possibly containing ordnance is proposed for reuse, a visual check is proposed. Further information may be required as to how it will be visually inspected, e.g. will the material be screened through some sort of trommel? You should be satisfied that the inspection regime adequately determines the suitability or otherwise for reuse of the material on the site. This will be required as part of the Material Management Plan.

From: Evans Lewis Alun (Rh-CTGC) [[email protected]] Sent: 24 July 2015 10:56 To: O'Connor, Colin Cc: Anderson, Catherine; Heather, Stuart; Gruffudd Glyn Llewelyn (Rh-CTGC) Subject: RE: Noise survey, Glyn Rhonwy

Morning Colin,

Apologies for not responding sooner.

Thank you for the baseline survey report.

In general the survey followed our agreed terms.

Some niggles…

I note that the survey was hampered by construction works on the A4086 . Where 25% of the monitoring locations were affected by unrepresentative noise (daytime) consideration should have been given to returning to the affected locations at a later date to measure levels.

I also note that minimum non attended measurement period of 24 hours were undertaken at locations where it was practicable to do so / applicable.

Some questions…..

1. Points 3.3 + 3.4 of the report. Construction activities hampered the daytime measurements at positions 3 + 6 . Attended (short term)measurements were undertaken during the evening and night time periods. Why were monitoring stations not left at these locations during the evenings / night times? 2. Point 5.3 / Table 3. Unsure as to what the measurement periods actually were. Daytime survey data between 07:00-23:00 on 14-15/4. Point 1 below table states daytime measurements over 2 consecutive dates. To clarify, do I take it that the results are a combination of two sets of daytime monitoring – i.e., 07:00-23:00 on the 14th and 07:00-23:00 on the 15th ? 3. Point 5.4, Table 4. Again, some confusion as to the actual measurement period. Do I take it that the results were obtained over 1 measurement period i.e. one period from 23:00 on 14th to 07:00 on the 15th?

Hwyl,

Alun

Please find attached our updated baseline noise survey report for the Glyn Rhonwy site.

This has been carried out following the methodology previous issued to you, with inclusion of longer monitoring periods as requested.

As in Stuart’s email below, there were some issues with non-typical noise sources in some areas (e.g. construction works) which did not allow us to do 24-hour continuous unattended measurements at all locations. Instead at some of the locations we carried out attended monitoring in order to allow for observations of the noise climate and measurements of the representative background noise levels (rather than that including extraneous noise sources e.g. construction works).

Can you please advise if you are satisfied with the contents of this report, or if you have any further comments regarding the results?

Alun, 2 My colleagues made a site visit last week and informed me that there is significant construction activity at the Caravan park site. Considering this, there would not be much value in long term unattended monitoring at this location. There are also issues of protecting our equipment from damage and keeping them secure. It is thus instead proposed to undertake only short term attended measurements at this location during day and night time periods. We still propose to undertake longer survey periods at all existing residential/ guest house properties.

Alun,

Following your comments we propose to make minimum 24 hour measurements at each location supplemented with attended ‘spot check’ measurements during daytime and night time periods to make observations on noise climate, weather conditions etc.

Do you find this approach suitable?

Stuart

Morning Stewart,

The short answer to your question is yes.

In establishing background noise levels we take the view that the longer the measurement the more representative the results are likely to be. The fact that such measurements are likely be unattended is an acceptable compromise.

Alun From: Heather, Stuart [mailto:[email protected]] Sent: 23 March 2015 17:00 To: Evans Lewis Alun (Rh-CTGC) Subject: RE: Noise survey, Glyn Rhonwy

Alun,

Thank you for your comments.

Do you consider that unattended longer surveys (24 hours, for instance) may give a better representation of the noise baseline?

Stuart

Good afternoon Stuart.

Thank you for the baseline airborne noise survey methodology for Glyn Rhonwy.

I can confirm that we accept;

1. The choice of monitoring locations 2. The equipment to be used / method of measurement.

However, I think it worthwhile to challenge the proposal in terms of the amount of time you intend to monitor for at each location – 90 minutes?.

90 minutes of additional data at each location cannot be taken to represent the predominant baseline conditions in the locality . The value of obtaining such limited data is questionable.

Alun

Alun,

AECOM is carrying out a update to the Environmental Statement for the Glyn Rhonwy development. This involves a baseline noise survey for the Noise and Vibration chapter. Could you please review the attached methodology and provide your opinions of the scope of monitoring and choice of measurement locations? We would also welcome any other comments you may have on the survey.

Catherine

Sincerest apologies for not responding sooner regarding this matter.

Meeting Minutes

Section 1.3 – please note that the officer’s name is Alun Evans and not Alun Hughes as noted. I’m aware that Alun did respond to Colin O’Connor in an e-mail sent on 24th July 2015, i assume that this was sufficient in relation to the matter of the noise monitoring briefing note previously sent to him on 18th June 2015.

The main content of the notes are in relation to matters of interest to Natural Resources Wales, i’m aware that Gareth Thomas has responded to these matters in a letter to you dated 31st July.

From Gwynedd Council’s point of view, there weren’t many direct issues for us to deal with. You have requested whether both NRW and GC will wish to review the updated Zetica report prior to submission of ES. I’m not sure what the viewpoint of NRW is regarding this matter, i assume that if there aren’t entirely new matters of interest raised, its review would not be necessary prior to the submission of the ES.

Scheme revision briefing note

It is appreciated that as further surveys are carried out within the site, that new or additional information becomes apparent which may require amendments to the scheme as approved. In this instance, survey works carried out within Q6 and Q1 now shows that capacities are now different to what was previously envisaged. You confirm that these changes will not lead to any physical changes in terms of the scale of dams but will result in additional slate waste arisings. This will need to be reviewed in terms of its visual effect and consideration must also be given to any potential run off which may feed into the Nant y Betws stream which is a tributary of Afon Gwyrfai SAC. I would urge you to discuss the matter of waste arisings with the North Wales Minerals and Waste Planning Service.

Noise – any amendments proposed must be considered in terms of noise impact, which you should discuss in full with Alun Evans.

Highways – although unlikely, but further amendments to the scheme may need to be considered in terms of highway impact, it is advised that you discuss any matter with Gareth Roberts.

Llyn Padarn pumping station – it is acknowledged that the re-location of the associated pumping station has been considered in light of concerns shown by members of the public.

It is agreed that the scale of development will not physically alter to any substantive degree, however, the consequence of any changes must be considered and assessed in full when apparent with previously agreed method statements and any other relevant information amended to highlight any new amendments. The Council reserves the right to comment on any further amendments as given and on their own individual merit.

Regards
