Mae Rheoliadau’r AEA yn gweithredu proses sgrinio sy’n gwerthuso effaith posib prosiectau amaethyddol arfaethedig ar dir sy’n cael ei gyfrif fel tir lled-naturiol ac/neu heb ei drin.  Nid yw’r Rheoliadau’n cael eu creu i atal gweithgarwch amaethyddol rhag digwydd ac nid ydynt yn rhwystro ffermio.  Caiff hyn ei gefnogi gan data a gasgwlyd ers cyflwyno’r drefn AEA yn 2002.  Hyd yma, mae Llywodraeth Cymru wedi ystyried 924 o geisiadau ac wedi rhoi caniatád i’r prosiectau fynd yn eu blaenau yn 93% o achosion.
The EIA Regulations operate a screening process which evaluates the potential impact of proposed agricultural projects on land which is classed as semi-natural and/or uncultivated. The Regulations are not put in place to prevent agricultural activity from taking place and are not a barrier to farming. This is supported by data collected since the introduction of the EIA regime in 2002.  To date, the Welsh Government has considered 924 applications and given permission for the projects to proceed in 93% of cases.
