(a) os bydd disgrifiad y sylwedd hwnnw, y peth a gymysgir neu'r peth a baratoir yng ngholofn 1 o Ran A neu Ran B o Atodlen 1 i'r Rheoliadau Sylweddau Peryglus fel y mae cyn i'r Rheoliadau hyn ddod i rym yn cael ei ddiwygio o ganlyniad i ddyfodiad y Rheoliadau hyn i rym; a

(b) os yw'r cydsyniad sylweddau peryglus yn bodoli mewn perthynas â'r sylwedd hwnnw, y peth a gymysgir neu'r peth a baratoir sydd dan sylw yn union cyn dyfodiad y Rheoliadau hyn i rym.

(2) Mewn perthynas â sylwedd, peth a gymysgir neu beth a baratoir y mae'r rheoliad hwn yn gymwys iddo, caniateir anwybyddu'r diwygiadau a wneir gan y Rheoliadau hyn wrth ddehongli'r cydsyniad sylweddau peryglus i'r graddau y mae'n ymwneud â'r sylwedd hwnnw, y peth a gymysgir neu'r peth a baratoir neu'r maintioli ohono sydd dan reolaeth.

(3) Mae paragraff (2) yn peidio â bod yn gymwys os yw'r cydsyniad sylweddau peryglus mewn perthynas â'r sylwedd hwnnw, y peth a gymysgir neu'r peth a baratoir neu'r maintioli ohono sydd dan reolaeth yn cael ei addasu gan yr awdurdod sylweddau peryglus ar 19 Mawrth 2010 neu wedi hynny.

PART B CATEGORIES OF SUBSTANCES AND PREPARATIONS NOT SPECIFICALLY NAMED IN PART A

Column 1	Column 2
Categories of hazardous substances		Controlled Quantity (Q) in tonnes
NOTES TO PART B 1. Substances and preparations must be classified for the purposes of this Schedule according to regulation 4 of the Chemicals (Hazard Information and Packaging for Supply) Regulations 2009(14) (CHIP) whether or not the substance or preparation is required to be classified for the purposes of those Regulations or, in the case of a pesticide approved under the Food and Environment Protection Act 1985(15), in accordance with the classification assigned to it by that approval. 2. An “explosive” means: a substance or preparation which creates the risk of an explosion by shock, friction, fire or other sources of ignition (risk phrase R2), a substance or preparation which creates extreme risks of explosion by shock, friction, fire or other sources of ignition (risk phrase R3), or a substance, preparation or article covered by Class 1 of the European Agreement concerning the International Carriage of Dangerous Goods by Road (UN/ADR), concluded on 30 September 1957, as amended, as transposed by Council Directive 94/55/EC of 21 November 1994 on the approximation of the laws of the Member States with regard to the transport of dangerous goods by road (16). Included in this definition are pyrotechnics, which for the purposes of these Regulations are defined as substances (or mixtures of substances) designated to produce heat, light, sound, gas or smoke or a combination of such effects through self-sustained exothermic chemical reactions. Where a substance or preparation is classified by both UN/ADR and risk phrase R2 or R3, the UN/ADR classification must take precedence over assignment of risk phrases. Substances and articles of Class 1 are classified in any of the divisions 1.1 to 1.6 in accordance with the UN/ADR classification scheme. The divisions concerned are: Division 1.1: Substances and articles which have a mass explosion hazard (a mass explosion is an explosion which affects almost the entire load virtually instantaneously). Division 1.2: Substances and articles which have a projection hazard but not a mass explosion hazard. Division 1.3: Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard: (a) combustion of which gives rise to considerable radiant heat; or (b) which burn one after another, producing minor blast or projection effects or both. Division 1.4: Substances and articles which present only a slight risk in the event of ignition or initiation during carriage. The effects are largely confined to the package and no projection of fragments of appreciable size or range is to be expected. An external fire will not cause virtually instantaneous explosion of virtually the entire contents of the package. Division 1.5: Very insensitive substances having a mass explosion hazard which are so insensitive that there is very little probability of initiation or of transition from burning to detonation under normal conditions of carriage. As a minimum requirement they will not explode in the external fire test. Division 1.6: Extremely insensitive articles which do not have a mass explosion hazard. The articles contain only extremely insensitive detonating substances and demonstrate a negligible probability of accidental initiation or propagation. The risk is limited to the explosion of a single article.   ” 3. In categories 6, 7, 8 and 9, “flammable”, “highly flammable”, and “extremely flammable” mean— (a) flammable liquids means substances and preparations having a flash point equal to or greater than 21 °C and less than or equal to 55°C (risk phrase R 10), supporting combustion; (b) highly flammable liquids means— (i) substances and preparations which may become hot and finally catch fire in contact with air at ambient temperature without any input of energy (risk phrase R 17); (ii) substances and preparations which have a flash point lower than 55°C and which remain liquid under pressure, where particular processing conditions, such as high pressure or high temperature, may create major-accident hazards; and (iii) substances and preparations having a flash point lower than 21 °C and which are not extremely flammable (risk phrase R 11, second indent); (c) extremely flammable gases and liquids means— (i) liquid substances and preparations which have a flash point lower than 0 °C and the boiling point (or, in the case of a boiling range, the initial boiling point) of which at normal pressure is less than or equal to 35 °C (risk phrase R 12, first indent), (ii) gases which are flammable in contact with air at ambient temperature and pressure (risk phrase R12, second indent), which are in a gaseous or supercritical state, and (iii) flammable and highly flammable liquid substances and preparations maintained at a temperature above their boiling point.
NOTES TO PARTS A AND B 1. Mixtures and preparations must be treated in the same way as pure substances provided they remain within the concentration limits set according to their properties under the relevant provisions specified in CHIP, unless a percentage composition or other description is specifically given. 2. In the case of substances and preparations with properties giving rise to more than one classification the lowest thresholds must apply. 3. Where a substance or group of substances listed in Part A also falls within a category of Part B, the controlled quantities set out in Part A must be used. 4. In the case of an establishment where no individual substance or preparation is present in a quantity above or equal to the relevant controlled quantity for that substance or preparation, the addition of hazardous substances to determine the controlled quantity must be carried out according to the following rule: If the sum— q1 / Q + q2 / Q + q3 / Q + q4 / Q + q5 / Q +  . . . isgreaterthanorequalto1 (where qx = the quantity of hazardous substance x (or category of substance) present, Q = the relevant controlled quantity (Q) from Part A or Part B, except for those substances for which column 3 of Part A contains a quantity Q*, in which case the quantity Q* must be used in place of the controlled quantity Q in column 2) then the controlled quantity of each of the substances which are added together in accordance with each of paragraphs 5(a) to (c) below must be deemed to be present for the purposes of sections 4(2), 14(2)(c), 23(2)(a) and of section 181 (enforcement notice to have effect against subsequent development) of the Town and Country Planning Act 1990(17) as substituted by paragraph 8 of Schedule 4. 5. The addition rule in paragraph 4 will apply for the following circumstances:— (a) for the addition of substances and preparations named in Part A and classified as toxic or very toxic, together with substances and preparations falling into categories 1 or 2 of Part B; (b) for the addition of substances and preparations named in Part A and classified as oxidising, explosive, flammable, highly flammable, or extremely flammable, together with substances and preparations falling into categories 3, 4, 5, 6, 7, 8 or 9 of Part B; (c) for the addition of substances and preparations named in Part A and classified as dangerous for the environment (R50 (including R50/53) or R51/53), together with substances and preparations falling into categories 10(i) or 10(ii) of Part B.

PART C SUBSTANCES USED IN AN INDUSTRIAL CHEMICAL PROCESS

Column 1	Column 2
Hazardous substances	Controlled quantity
NOTES TO PART C 1. The expression “which it is believed may be generated during loss of control of an industrial chemical process” has the same meaning as in the Directive. 2. Where a substance falling within Part A or B also falls within Part C, the classification with the lowest controlled quantity must apply, subject to note 3 to the notes to Parts A and B.”
Where it is believed that a substance, which is within Part A or Part B, may be generated during loss of control of an industrial chemical process ( “HS”), any substance which is used in that process ( “S”).	The amount of S which it is believed may generate, on its own or in combination with other substances used in the relevant industrial chemical process, the controlled quantity of the HS in question.

Nodyn Esboniadol

(Nid yw'r nodyn hwn yn rhan o'r Rheoliadau)

Mae'r Rheoliadau hyn yn rhoi ei heffaith, mewn perthynas â chynllunio gwlad a thref yng Nghymru, i Erthygl 12 o Gyfarwyddeb 96/82/EC ar reoli'r peryglon o ddamweiniau mawr yn ymwneud â sylweddau peryglus (O.J. Rhif L 10, 14.1.1997, t.13)(Cyfarwyddeb Seveso II), fel y'i diwygiwyd gan Gyfarwyddeb y Cyngor 2003/105/EC (O.J. Rhif L 345, 31.12.2003, t.97) (Cyfarwyddeb 2003).

Mae Erthygl 12 o Gyfarwyddeb Seveso II yn ei gwneud yn ofynnol i bolisïau defnyddio tir roi sylw i'r amcanion o rwystro damweiniau mawr a chyfyngu ar ganlyniadau damweiniau o'r fath; ac fod yr amcanion hyn yn cael eu cyflawni drwy reolaethau a'r gofyniad i sicrhau fod awdurdodau cynllunio yn llunio gweithdrefnau ymgynghori priodol er mwyn hwyluso rhoi'r polisïau hyn a pholisïau eraill a sefydlwyd o dan yr Erthygl hon ar waith. Mae hefyd yn ei gwneud yn ofynnol i Aelod-wladwriaethau roi sylw i'r angen, dros y tymor hir, i gynnal pellteroedd priodol rhwng sefydliadau a gwmpesir gan y Gyfarwyddeb ac ardaloedd preswyl, ardaloedd a ddefnyddir gan y cyhoedd, ac ardaloedd o sensitifrwydd naturiol neu o ddiddordeb naturiol. Mae Cyfarwyddeb 2003 yn estyn y gofyniad hwn i gynnwys adeiladau a ddefnyddir gan y cyhoedd, prif lwybrau trafnidiaeth cyn belled ag y mae modd, ac ardaloedd hamddena.

Mae'r diwygiadau a wnaed gan Gyfarwyddeb 2003 hefyd yn estyn cwmpas Cyfarwyddeb Seveso II drwy ddiwygio Atodiad I i Gyfarwyddeb Seveso II (cymhwyso Cyfarwyddeb Seveso II). Mae Atodiad I yn gymwys i bresenoldeb sylweddau peryglus (gan gynnwys pethau a gymysgir a phethau a baratoir) mewn unrhyw sefydliad. Wrth wneud felly, mae Atodiad I yn penderfynu cymhwysedd Erthygl 12. Mae'r Atodiad I newydd yn cynyddu'r amrediad o sylweddau peryglus, ac yn adolygu'r diffiniadau o'r sylweddau peryglus a restrwyd yn Atodiad I o Gyfarwyddeb Seveso a'r maintioli ohonynt sy'n dod â hwy o fewn cwmpas y Gyfarwyddeb. Ymhlith y sylweddau peryglus hynny sydd bellach wedi'u cynnwys yn rhinwedd y diwygiadau a wnaed gan Gyfarwyddeb 2003 y mae'r rheini sy'n gysylltiedig â pheryglon sy'n codi o weithgareddau storio a phrosesu penodol mewn mwyngloddio.

Mae rheoliad 3 yn diwygio Rheoliadau Cynllunio (Sylweddau Peryglus) 1992 (y Rheoliadau Sylweddau Peryglus) drwy osod yn ei lle Atodlen 1 newydd sy'n rhagnodi'r sylweddau sy'n sylweddau peryglus a'r maintioli ohonynt sydd dan reolaeth, er mwyn rhoi eu heffaith i'r diwygiadau a wnaed i Atodiad I o Gyfarwyddeb Seveso II gan Gyfarwyddeb 2003. Mae rheoliad 2 hefyd yn gwneud rhai mân ddiwygiadau i adlewyrchu'r ffaith bod Atodlen 1 newydd wedi cael ei gosod yn ei lle.

Mae rheoliad 4 yn gwneud darpariaeth drosiannol er mwyn sicrhau nad yw cydsyniadau presennol ar sylweddau peryglus yn cael eu trin fel rhai annilys oherwydd fod sylweddau peryglus wedi cael eu hail enwi neu eu hail gategoreiddio.

Mae rheoliad 5 yn rhoi imiwnedd drosiannol rhag erlyniad ac achosion o dramgwydd am gyfnod o chwe mis o'r diwrnod pan ddaw'r Rheoliadau hyn i rym. Yn ystod yr adeg hon, caniateir gwneud cais am gydsyniad.

Paratowyd asesiad effaith mewn perthynas â'r Rheoliadau hyn. Fe'i gosodwyd yn Llyfrgell Llywodraeth Cynulliad Cymru a gellir cael copïau ohono oddi wrth y Gyfarwyddiaeth Gynllunio, Llywodraeth Cynulliad Cymru, Parc Cathays, Caerdydd CF 10 3NQ.

1990 p.10; cafodd adran 4 ei diwygio gan O.S. 1999/981; mae yna ddiwygiadau eraill nad ydynt yn berthnasol i'r Rheoliadau hyn. Mae'r pwerau hyn bellach wedi'u breinio yng Ngweinidogion Cymru i'r graddau y maent yn arferadwy o ran Cymru. Fe'u trosglwyddwyd i Gynulliad Cenedlaethol Cymru gan Erthygl 2 o Orchymyn Cynulliad Cenedlaethol Cymru (Trosglwyddo Swyddogaethau) 1999 ac Atodlen 1 iddo (O.S. 1999/672) a'u trosglwyddo wedi hynny i Weinidogion Cymru gan adran 162 o Ddeddf Llywodraeth Cymru 2006 a pharagraff 30 o Atodlen 11 iddi (p.32).
