Local authorities have various powers under the Environmental Protection Act 1990 to address issues of waste, statutory nuisance and litter in their area.
Mae gan awdurdodau lleol amrywiol bwerau dan Ddeddf Diogelu’r Amgylchedd 1990 i fynd i’r afael â materion gwastraff, niwsans statudol a sbwriel yn eu hardal.
