b'Sections 74 (as amendedsee below), 74A, 74B and 75 (subject to potential amendmentsee below) of the 1991 Act enable the Secretary of State to make regulations requiring an undertaker who is executing street works to pay a charge to the highway authority where the duration of the works exceeds such period as may be prescribed and the works are not completed within a reasonable period or in relation to the duration of the works. The charges are to be fixed in regulations but will relate to both for the extra time taken to complete the works and to the extent to which the surface of the highway is affected by the works. Different rates may be applied for different places and times and according to other relevant factors. Section 75 entitles a street authority to charge fees for the carrying out of inspections during the carrying out of street works. The fees are to be prescribed in regulations and are to be distinguished from the costs which the undertaker may have to meet in relation to inspections consequent upon the failure to comply with duties of reinstatement. Section 74 has been amended by the Transport Act 2000 to include sub-section (2A) which provides that the regulations may prescribe exemptions from the requirement to pay charges. The regulations must not provide for charges to be paid unless the Secretary of State has approved this by order (section 74A(2)). Section 75 is to be replaced by different wording as provided by the Traffic Management Act 2004, section 58(2)not yet appointed. The following statutory instruments are now in place: the Street Works (Inspection Fees) (England) Regulations 2002, SI 2002/2092 the Street Works (Inspection Fees) (England) (Amendment) Regulations 2004 (SI 2004/572); the Street Works (Inspection Fees) (Wales) Regulations 2006 (SI 2006/1532); the Street Works (Inspection Fees) (Wales) (Amendment) (No 2) Regulations 2008 (SI 2008/1213); the Street Works (Inspection Fees) (England) (Amendment) Regulations 2009 (SI 2009/104); and the Street Works (Inspection Fees) (Wales) (Amendment) Regulations 2009 (SI 2009/258). The Street Works (Charges for Occupation of the Highway) (England) Regulations 2012 (SI 2012/425) give a local highway authority the power to charge undertakings carrying out works (eg utilities) on a public highway subject to certain conditions and parameters. This will allow local highway authorities to cover the costs (or some of them at least) of providing alternative rates and other assistance. The main restriction on using this power is that each individual scheme will have to be approved by the Secretary of State. To date, two schemes have been approvedthe TFL Lane Rental Scheme and the Kent Lane Rental Scheme. Sections 50, 51 and Schedule 3 to the 1991 Act give authorities a discretion to recover legal and other expenses incurred in granting street works licences to undertakers enabling them to place and maintain apparatus in or under a highway and also to charge an annual fee for administering such licence. Where such licence expires, an authority may remove or alter the apparatus and recover their reasonable expenses. Section 53 requires a street authority to keep a register of street works, and other types of works, and the Secretary of State has power by regulation to make provision requiring the payment of such fees as may be prescribed in respect of the 123'
