Provision is made for the raising of threshold levels in the 1986 Act – most recently set in section 34 of the 1998 Act – in respect of various industrial incentive instruments, above which Government approval is required for the agency concerned to proceed with payments to individual industrial projects. The existing thresholds were set in 1998 and, taking inflation into account, this has resulted in a significant increase in the number of projects which require Government approval. The threshold for capital grants is raised in section 34(f), that for employment grants is raised in section 28, that for equity provision is raised in section 31, the aggregate threshold for all investment aid is revised and raised in section 32, the threshold for training grants is raised in section 29 and the threshold for research and development grants is raised in section 30. The existing provisions on employment grants and research and development grants are redrafted to take account of current practice in using these instruments – employment grants are dealt with in sections 27 and 28, and research and development grants in section 30.
