  22. Gwybodaeth Mae copi o lythyr D"{r Cymru wedi'i amgáu, sy'n cynghori ar yr angen am Gymeradwyaeth SUDS gan yr Awdurdod Cymeradwo SUDS (SAB), y potensial i garthffosydd cyhoeddus neu ddraeniau ochrol fod yn bresennol a mesurau effeithlonrwydd d"{r. Mae'r hysbysiad penderfyniad hwn yn ymwneud yn unig â Deddf Cynllunio Gwlad a Thref 1990 (fel y'i diwygiwyd) ac nid yw'n honni rhoi unrhyw gymeradwyaeth, a allai fod yn ofynnol o dan unrhyw ddarpariaethau deddfwriaethol ar wahân. Fe'ch cynghorir i gysylltu â Rheoli Adeiladu i ganfod a fydd angen eu cymeradwyaeth ar gyfer y datblygiad arfaethedig. Mae'r hysbysiad penderfyniad hwn yn ymwneud yn unig â Deddf Cynllunio Gwlad a Thref 1990 (fel y'i diwygiwyd) ac nid yw'n honni rhoi unrhyw gymeradwyaeth, a allai fod yn ofynnol o dan unrhyw ddarpariaethau deddfwriaethol ar wahân neu gan unrhyw berchnogion tir eraill.
