Forslag til Rådets Afgørelse om Det Europæiske Fællesskabs tiltrædelse af regulativ nr. 67 fra De Forenede Nationers Økonomiske Kommission for Europa om typegodkendelse af særligt udstyr til LPG-drevne biler /* KOM/99/0014 endelig udg. - AVC 99/0018 */





(forelagt af Kommissionen) BEGRUNDELSE 1. Baggrund EF er ved Raadets afgoerelse 97/836/EF af 27. november 1997 blevet kontraherende part i den reviderede overenskomst af 1958 under FN's OEkonomiske Kommission for Europa (FN/ECE) fra 24. marts 1998 og har samtidig tiltraadt de 78 regulativer, der er knyttet til overenskomsten. Afgoerelsens artikel 3, stk. 3, bestemmer bl.a., at Faellesskabet kan beslutte at anvende et FN/ECE-regulativ, som det ikke tiltraadte ved tiltraedelsen af den reviderede overenskomst, naar Raadet har godkendt regulativet med kvalificeret flertal efter samstemmende udtalelse fra Europa-Parlamentet. Paa det 116. moede i arbejdsgruppen vedroerende koeretoejers konstruktion under FN/ECE blev der vedtaget en aendring til regulativ nr. 67 om typegodkendelse af saerligt udstyr til LPG-drevne biler. Dette regulativ er ikke naevnt paa listen i bilag II til afgoerelse 97/836/EF over regulativer, som EF har tiltraadt. Det saaledes aendrede regulativ nr. 67 tager bl.a. sigte paa at fjerne de tekniske hindringer for samhandelen med motorkoeretoejer mellem de kontraherende parter, samtidig med at der opnaas en hoej grad af sikkerhed og miljoebeskyttelse. De er vigtigt at fremhaeve, at EF kun kan tiltraede det aendrede regulativ nr. 67, hvis aendringerne virkelig traeder i kraft paa de(n) deri anfoerte dato(er). Endvidere skal regulativet integreres i systemet for typegodkendelse af koeretoejer og saaledes supplere gaeldende faellesskabslovgivning. Det understreges, at det er paa grundlag af de dokumenter, der foreligger paa de officielle FN/ECE-sprog (fransk, engelsk og russisk), EF traeffer afgoerelse om tiltraedelse af regulativet. Derfor er teksten til regulativ nr. 67 kun vedlagt paa engelsk og fransk. Som fastsat i artikel 4, stk. 5, i afgoerelse 97/836/EF offentliggoeres regulativ nr. 67 dog i EF-Tidende paa alle de officielle EF-sprog, inden det traeder i kraft. 2. Indholdet i udkastet til beslutning Udkastet til beslutning skal saette Faellesskabet i stand til at tiltraede FN/ECE-regulativ nr. 67 om typegodkendelse af saerligt udstyr til LPG-drevne biler. *** Forslag til RAADETS AFGOERELSE om Det Europaeiske Faellesskabs tiltraedelse af regulativ nr. 67 fra De Forenede Nationers OEkonomiske Kommission for Europa om typegodkendelse af saerligt udstyr til LPG-drevne biler RAADET FOR DEN EUROPAEISKE UNION HAR - under henvisning til traktaten om oprettelse af Det Europaeiske Faellesskab, under henvisning til Raadets afgoerelse 97/836/EF af 27. november 1997 om Det Europaeiske Faellesskabs tiltraedelse af overenskomsten under FN's OEkonomiske Kommission for Europa om indfoerelse af ensartede tekniske forskrifter for hjulkoeretoejer samt udstyr og dele, som kan monteres og/eller benyttes paa hjulkoeretoejer, samt vilkaarene for gensidig anerkendelse af godkendelser, der er meddelt paa grundlag af saadanne forskrifter ("Overenskomst af 1958 som revideret") (1), saerlig artikel 3, stk. 3, og artikel 4, stk. 2, andet led, og (1) EFT L 346 af 17.12.1997, s. 78. under henvisning til forslag fra Kommissionen (2), (2) EFT C under henvisning til samstemmende udtalelse fra Europa-Parlamentet (3), (3) EFT C ud fra foelgende betragtninger: (1) Det aendrede regulativ nr. 67 om typegodkendelse af saerligt udstyr til LPG-drevne biler, fjerner de tekniske hindringer for samhandelen med motorkoeretoejer mellem de kontraherende parter, for saa vidt angaar saerligt udstyr til LPG-drevne biler; med de ensartede forskrifter i naevnte regulativ opnaas en hoej grad af sikkerhed og miljoebeskyttelse; (2) det aendrede regulativ nr. 67 er meddelt de kontraherende parter og traeder i kraft paa de(n) deri anfoerte dato(er) som et til den reviderede overenskomst af 1958 knyttet regulativ for alle de kontraherende parter, der ikke har givet meddelelse om, at de ikke kan tilslutte sig det; (3) regulativet boer integreres i systemet for typegodkendelse af koeretoejer og saaledes supplere gaeldende faellesskabslovgivning - TRUFFET FOELGENDE AFGOERELSE: Eneste artikel Det Europaeiske Faellesskab tiltraeder FN/ECE-regulativ nr. 67 om typegodkendelse af saerligt udstyr til LPG-drevne biler, saaledes som det er aendret og meddelt de kontraherende parter (4), for saa vidt som aendringen traeder i kraft paa de(n) deri anfoerte dato(er).
