From: Slack, Chloe To: DEFA, Planning Subject: 25/90134/B Date: 04 March 2025 11:56:49 Attachments: image001.png image002.png Dear planning,

Please see below comments in relation to the above planning application.

Application Number: 25/90134/B Proposal: Installation of a flue Site Address: 16 Brewery Wharf Castletown Isle Of Man IM9 1EU

Department: Department of Environment, Food & Agriculture (DEFA) Section: Environmental Health Unit Officer/Title: Chloe Slack Environmental Health Officer Contact Number: 685894

General Stance: Please note this opinion is based on the plans provided for the planning application and a site visit has not been carried out.

We do not object to the proposal.

The plans do not appear to indicate an obvious risk of a smoke nuisance, however the following should be considered;

1. Building Regulations do not consider the potential impacts that the products of combustion from solid fuel appliances can have on neighbouring premises. Compliance with building control requirements may not, therefore, be sufficient to prevent smoke nuisance being caused to neighbouring premises.

2. Ensuring that flues discharge at a height that allows products of combustion to disperse upwards into the atmosphere, and not back down to the ground or towards neighbouring properties, is the main method of preventing smoke nuisance.

3. Factors that may affect the likelihood of a nuisance occurring include: The topography of the surrounding land. The height of neighbouring premises in relation to the termination of a flue. Construction characteristics of neighbouring properties, e.g. trickle vents in windows and ventilated soffits that provide ventilation to ‘cold roofs’. Local wind patterns/the prevailing wind direction. The Isle of Man is often windy and is classified in Approved Document C as being a severe/very severe exposure zone for driving rain. Localised effects on the movement of air around buildings, e.g. the formation of eddies can draw smoke towards the ground/ impede its dispersal into the atmosphere above.

4. It may not be possible/ practicable in all circumstances to install a flue that discharges smoke at a height that won’t cause a nuisance to neighbouring premises.

5. Other factors that can affect the impact of smoke on neighbouring premises include: Fuel quality - wet/ damp wood produces more smoke than well-seasoned/dried wood. The burning of rubbish on a fire, particularly plastics, produces particularly pungent smoke and should generally be avoided. Insufficient airflow - this can cause fuel to smoulder and produce excessive smoke. Cowls fitted to the termination of a flue.

The installation of solid fuel stoves/burners is not a necessity in properties with modern heating systems. Where complaints are received concerning a smoke nuisance the matter could be investigated and, where complaints are found to be justified, formal action taken requiring the abatement of the nuisance. Therefore it is recommended that the above matters are considered at this stage to reduce the likelihood of any undue impact on neighbouring premises, and the potential requirement for alterations at a later date.

Kind regards, Chloe
