Thema ganolog i lawer o’r ymatebion i'r Papur Gwyn yw bod gofyn am arian ac adnoddau sylweddol i sefydlu a chynnal y drefn newydd.  Mae yna bryderon hefyd ynghylch sicrhau nad oes baich anghymesur yn cael ei roi ar berchnogion tomenni.  Rwy'n cydnabod y pwyntiau hyn ac yn ymrwymo i sicrhau tryloywder ynghylch costau wrth ddatblygu’r ddeddfwriaeth. Mae'n werth ailadrodd hefyd y gall llawer o gyfleoedd economaidd, cymdeithasol ac amgylcheddol ddod o fuddsoddi mewn tomenni segur, gyda llawer ohonynt yn digwydd yn rhai o ardaloedd mwyaf difreintiedig Cymru.
A key theme to emerge consistently in responses to the White Paper is the significant funding and resource requirements to establish and implement the new regime.  There are also separate concerns around ensuring a disproportionate burden is not placed on tip owners.  I acknowledge these points and commit to ensure transparency around costings as the legislation is developed. It is also worth reiterating there are many economic, social and environmental opportunities that might be gained from investing in disused tips, many of which are located in some of the most deprived areas of Wales.
