40. .Sections 3 and 4: Existing impounding works.
The new restriction on impounding introduced by section 2 does not apply retrospectively. However, there are impounding works that are unlicensed, either because their construction pre-dated the licensing regime or a licence has been revoked and some of these works are, or in the future may, cause environmental problems that cannot be addressed by the Agency under its current powers. Section 3 provides the EA with a new power to serve notice to require that an impounding licence is obtained and failure to comply with such a notice would be an offence. Section 4 provides the EA with a power to serve a works notice on the relevant person (normally the owner) to carry out remedial works on an existing impoundment that is causing environmental damage. Failure to comply with the notice is an offence.
41.Provisions in these sections are devolved to the Assembly.
