What is happening?
CYFOETH NATURIOL CYMRU
CYHOEDDIAD O FWRIAD I BEIDIO Â PHARATOIDATGANIAD AMGYLCHEDDOL.
Rheoliad 12B Rheoliadau Asesu Effeithiau Amgylcheddol (Gwaith Gwella Draenio Tir) SI1999/1783 fel y’u diwygiwyd.
Dalgylch Clarach Uchaf – Gosod Grisiau Mynediad a Strwythur Mesur Llif.
Mae Cyfoeth Naturiol Cymru yn rhoi hysbysiad ei fod yn bwriadu gosod grisiau mynediad a x4 strwythur mesur llif yn y safleoedd canlynol yn nalgylch Clarach Uchaf, ger Cwmsymlog Ceredigion:
Ceuffordd Oliver: CGC SN6804183326 Gosod plât cored ‘hollt V’, gan gynnwys dyfais cofnodi, synhwyrydd pwysau a bwrdd mesur.
Ymchwydd Siafft Bushell: CGC SN6950083787 Gosod grisiau mynediad a phlât cored hollt hirsgwar cyfansawdd.
Pwynt Gollwng Tomen Bwlch: CGC SN7013082554 Gosod plât cored ‘hollt V’.
Pwynt Gollwng Ceuffordd Ddwfn Cwmerfyn: CGC SN6928482863 Gosod synhwyrydd cyflymder o fewn y bibell bresennol.
Mae angen gosod y strwythur monitro llif er mwyn monitro gollyngiadau o’r safle a chasglu data, i lywio’r gwaith o ystyried a dylunio mesurau cyweirio mewn mwyngloddiau metel yn y tymor hirach. Mae’r cynigion hyn yn rhan o Raglen Mwyngloddiau Metel Cymru ar y cyd rhwng Cyfoeth Naturiol Cymru a’r Awdurdod Adfer Safleoedd Mwyngloddio.
Mae Cyfoeth Naturiol Cymru o’r farn nad yw’r gwaith gwella yn debygol o effeithio’n sylweddol ar yr amgylchedd ac nid yw’n bwriadu paratoi datganiad amgylcheddol ar ei gyfer. Er nad oes bwriad o lunio datganiad amgylcheddol, mae’r cynllun wedi ystyried ffactorau amgylcheddol sy’n gysylltiedig â’r safle ac mae Cynllun Gweithredu Amgylcheddol yn cael ei baratoi ar gyfer y prosiect.
Gellir cael gwybodaeth am y Cynllun Gweithredu Amgylcheddol a dyluniad y cynllun gan y cyswllt isod.
Dylai unrhyw un sy’n dymuno cyflwyno sylwadau mewn perthynas ag effeithiau amgylcheddol tebygol y gwaith gwella arfaethedig wneud hynny, yn ysgrifenedig, a’u hanfon i’r cyfeiriad a nodir isod, o fewn 30 diwrnod i ddyddiad cyhoeddi’r hysbysiad hwn.

ANNOUNCEMENT OF INTENTION NOT TO PREPARE AN ENVIRONMENTAL STATEMENT.
Regulation 12B of the Environmental Impact Assessment (Land Drainage Improvement Works) SI1999/1783 as amended.
Upper Clarach Catchment – Access Steps and Flow Gauging Structure installations.
Natural Resources Wales gives notice that it proposes to install access steps and x4 flow gauging structures at the following sites in the Upper Clarach catchment, near Cwmsymlog Ceredigion:
Oliver’s adit: NGR SN6804183326 Installation of x1 flow structure install a ‘V-notch’ weir plate monitoring structure, including a logger, pressure sensor and gauge board.
Bushells shaft upwelling: NGR SN6950083787 Installation of access steps and a compound rectangular notch weir plate.
Bwlch reclaimed tip: NGR SN7013082554 install a ‘V-notch weir’ plate.
Cwmerfyn Deep Adit discharge: NGR SN6928482863 install a velocity sensor within the existing pipe.
The flow monitoring structure installation works are required for site discharge monitoring and data collection, to inform the consideration and design of longer term metal mine remediation measures. These proposals form part of the joint Wales Metal Mine Programme between NRW and the Mining Remediation Authority.
Natural Resources Wales considers that the improvement works are not likely to have significant effects on the environment and does not intend to prepare an environmental statement in respect of them. Although an environmental statement is not proposed, the scheme design has considered environmental factors associated with the site and an Environmental Action Plan (EAP) is being prepared for use during the project.
The EAP and scheme design information can be obtained from the contact below.
Any person wishing to make representations in relation to the likely environmental effects of the proposed improvement works should do so, in writing, to the address specified below, within 30 days of the date of publication of this notice.
