izindaba

I. Ukolweni owamukelwe kufanele uhlangabezane nezindinganiso ezithile, njengokuqukethwe komswakamo, ukuminyana ngobuningi kanye nokungcola kufanele uhlangabezane nezidingo zebanga elihambisanayo lokusanhlamvu okungaphekiwe.
B. Ukuhlanza kokuqala kususa ukungcola okukhulu, izitini, amatshe, izintambo zikakolweni.
C. Ukuhlanza ukolweni oluhlaza kususa ukungcola okukhulu (utshani bakakolweni, udaka), ukungcola okuncane, inhlabathi ye-lime, isihlabathi, njll.
D. Ukuhlola umoya kususa uthuli namakhoba kakolweni.
E. Ukuhlukaniswa kukamagnetic kususa ukungcola kwensimbi kazibuthe kukolweni.
F. Uhlamvu olungahluziwe luzofakwa esiseleni sikakolweni ongahluziwe ngemva kokuhlanzwa kokuqala.

Hlangana nezinga elilandelayo ngemva kokuhlanza:
(1) Khipha u-1% wokungcola okukhulu, u-0.5% wokungcola okuncane kanye nomhlabathi womcako.
(2) Khipha u-0.005% wokungcola kwensimbi kazibuthe kunhlamvu eluhlaza.
(4) Khipha u-0.1% wokungcola okukhanyayo ngezinto zokuhlola umoya.
(3) Ukolweni uyophakanyiswa futhi ugcinwe esiseleni sikakolweni oluhlaza.
(4) Umswakama kufanele ulawulwe ngaphansi kuka-12.5%, futhi okusanhlamvu okuluhlaza kufanele kuhlolwe njalo ukuze kuqinisekiswe ikhwalithi.
