A Defra representative said he could not reveal how many responses have been received but officials "are happy with the response".
The proposals in the joint Defra/Department for Communities & Local Government consultation mark a change from previous proposals that required planning authorities to establish separate SuDS approval bodies, but the adoption of these was delayed by problems establishing them and a dispute over who would pay for the SuDS' maintenance.
The consultation proposes strengthening planning policy, with an expectation that SuDS will be provided in all new major developments and planning officers and councillors will be able to consider them as an integral part of the planning process.
It would also give planning authorities the flexibility to ensure that the developer and future landowner have responsibility for maintenance. The consultation closes on 24 October.
