That's among the findings of the Industrial and Waste Licence Enforcement Summary.
The Environmental Protection Agency carried out 29 inspections on peat extraction sites last year.
It's one of the highlights in its Industrial and Waste Licence Enforcement Summary for 2023.
The report also states Bord Na Móna submitted 14 rehabilitation plans under the Peatlands and Climate Action Scheme, covering 4,289 hectares.
It also found odour and noise complaints remained the most common last year accounting for 90% of all complaints.
EPA Programme Manager Patrick Byrne says the reduction is mainly due to increased enforcement by the agency.
The EPA says it's engaging with two midlands local authorities to progress enforcement action in relation to peat extraction operations.
It's working with Offaly and Westmeath County Councils on the issue, as well as three other local authorities around the country.
It also revealed its first successful District Court Prosecution for the extraction of peat without a licence.
EPA Programme Manager Patrick Byrne says the majority of inspections are carried out unannounced:
