Speaking at the launch of his 1992-93 annual report, Dr Slater said that all sections of industry had responded constructively to IPC.
'We are now over two years into a five year programme of implementation.
'During the period of this report we received 530 applications for authorisation under IPC. This compares with a figure of 212 during the same period last year, an increase of 150%,' he said.
Dr Slater said HMIP maintained its firm stance in enforcing the regulations.
He said: 'HMIP has open to it a range of enforcement powers. We resort to prosecution only when it is clearly in the best interests of the environment, the public, and industry as a whole.
'During 1992-93 we brought 14 cases to court, all of which were successful. Fines totalled £101,000 with costs awarded to us of £64,102. This compares with 11 prosecutions brought in 1991-92.
Environment Minister Tim Yeo today welcomed the publication of the inspectorate's annual report, and said the implementation of IPC was an important cornerstone of the Environment Protection Act, the government's key 'green' initiative.
Mr Yeo said: 'We welcome the European Commission's proposals for a framework directive for integrated pollution control which was instigated by the UK. We look forward to securing an early agreement after the EC Council has discussed these proposals next week.'
