Part 3: National Underground Asset Register Section 56: National Underground Asset Register: England and Wales Section 106A: National Underground Asset Register
A key aspect of the new legislative framework for NUAR is the requirement, imposed by new section 106A(1) which is inserted into NRSWA 1991, for the Secretary of State to keep a register of information relating to apparatus in streets in England and Wales. This register is referred to in this Act as "NUAR" (as defined by subsection (2)) and is the central repository of information into which, in accordance with other provisions being inserted into NRSWA 1991, certain persons are required to enter information. In practice, NUAR is a digital register and the information within it will be used to form a digital underground map displaying information about apparatus installed beneath streets in England, Wales and Northern Ireland.
	Subsection (3) confers a power on the Secretary of State to prescribe, through regulations, the form and manner in which NUAR must be kept. Regulations under this subsection are subject to the negative procedure as provided for in subsection (5).
	Section 57 makes a number of amendments to NRSWA 1991Act, some of which require people to enter information into NUAR. In order to facilitate this, and as required by subsection (4), the Secretary of State must ensure the required people have access to NUAR.
	Section 58 (3) inserts Article 45A(1) into the Street Works (Northern Ireland) Order 1995 (SWNIO 1995). This imposes an obligation on the Secretary of State, equivalent to that set out in section 106A in relation to England and Wales, to keep a register of information relating to apparatus in streets in Northern Ireland. Subsection (6) allows the Secretary of State to discharge both obligations by keeping a single register which covers England, Wales and Northern Ireland.
