6.25 Progress is continuing in the development of the National Policy Statements (NPS), which provide certainty for users of the major infrastructure regime. The NPSs provide predictability for users of the regime, by setting out the need for major infrastructure for delivering energy needs by 2020 and encouraging growth. Six NPSs, related to energy infrastructure, are now designated, the ports NPS is due to be designated shortly, and the final three are due to be completed in 2012. The waste water NPS will be complete by January, the hazardous waste NPS by the summer and the national networks NPS by the end of 2012. In the interim, the Department for Transport have committed to publishing a draft national networks NPS by the end of 2011, and a joint ministerial statement on strategic rail freight interchange policy, which will be reflected in the national networks NPS, has now been made.
