This is a pre-recorded mini-webinar. It is available from 3 October 2022 to 31 March 2023. Fee = £65.00 plus VAT or 1 credit
The purpose of this webinar is to
provide an understanding of short term local air quality impacts that
may occur in the immediate vicinity of chimneys discharging pollutants
mainly from combustion processes. The need to approve the size of the
stack remains a legislative requirement under the Clean Air Act and, is
assessed in determining permits for Environmental Permitting
Regulations activities regulated by Local Authorities. Such calculations
are designed to protect local receptors from short term pollutant
impacts and nuisance from odorous pollutant exposure.
The webinar uses worked examples
to show the basis of the calculation and is designed to enable air
quality and planning professionals to have confidence to be able review
stack height calculations submitted as part of planning and permit
The webinar presents data that
demonstrate that a stack height determined using such calculation
procedures (HMIP D1 or Chimney Height Memoranda methods) should ensure
compliance with NAQS objectives.
