A wnaiff y Gweinidog roi rhesymau pam y bydd cost Rheoliadau Adnoddau Dŵr (Rheoli Llygredd Amaethyddol) (Cymru) 2021 dros 20 mlynedd £904 miliwn yn fwy na gwerth datganedig y buddion?

The Regulatory Impact Assessment (RIA) provides a detailed cost benefit analysis, demonstrating the range of costs and benefits varies considerably in different scenarios. The RIA assesses the possible cost benefit of the Regulations using the Net Present Value (NPV). The central estimates for the NPV, the costs and environmental benefit prices at medium levels, range between a net cost of £140million to a net benefit of £28 million, over 20 years.
