Professional kitchen fumes: documents and checks to complete before opening

Emission authorisation exemptions, design and declarations of conformity: what to check before opening and what a Court of Cassation case teaches.

An authorised restaurant may still be liable for nuisance emissions from its kitchen. The case examined in Court of Cassation judgment no. 13324/2020 shows why opening a business and installation adequacy require separate checks. Assessment should take place before service begins: waiting for complaints leaves an essential aspect of the premises' operation unresolved.

Cooking, capture, treatment and evacuation form a single technical route. The air cleaner is one element of it. Assessing the solution requires knowledge of the actual activity, installed configuration and documents describing its characteristics and conditions of use.

Emissions of low significance: what the exclusion means

Article 272(1) of D.Lgs. 152/2006 (reproduced in the notes to D.Lgs. 102/2020) excludes establishments consisting exclusively of installations and activities listed in Annex IV, Part I from the emission authorisation required by the relevant title. Limits and requirements specifically provided by the provisions cited in that article continue to apply.

Letter e of Annex IV, Part I includes kitchens, catering establishments, canteens, rotisseries and frying establishments. The exclusion concerns that specific environmental authorisation: it does not provide blanket permission to install any wall discharge. The configuration must also be checked against other applicable requirements.

Classification must consider all activities present. Where the same establishment also contains installations or activities outside the list, Article 272 distinguishes these for authorisation purposes. The premises' trading description therefore does not replace examination of the actual processes.

AUA depends on the environmental authorisations needed

D.P.R. 59/2013, Article 3 governs the Single Environmental Authorisation (AUA), which combines certain permits and requirements, including discharge authorisations, emission authorisations and specific acoustic formalities. This does not mean AUA is automatically required for every restaurant. Check which authorisations are required in the particular case. For activities subject only to notification or a general authorisation, the regulation allows operators not to use AUA while still proceeding through SUAP.

The declaration of conformity concerns the completed work

D.M. 37/2008 covers installations serving buildings within its scope, including ventilation, air supply and combustion product evacuation. For work falling under the decree, design, execution and declarations of conformity follow specific rules.

Article 7 requires the installing company to issue the declaration after the required checks, including functional checks. The design and materials report form an integral part of it. For partial refurbishments, documentation concerns the work undertaken while considering safety, functionality and compatibility with the existing installation. Article 8 requires the owner to preserve its safety characteristics, taking account of installer and manufacturer instructions.

The restaurant case before the Court of Cassation

Criminal Court of Cassation, Section III, judgment no. 13324 of 30 April 2020 examined a restaurant owner's appeal concerning nuisance vapours and fumes from a kitchen without a chimney. At appeal, the charge under Article 659 of the Criminal Code had been declared time-barred, while conviction under Article 674 had been upheld. The Court of Cassation ruled the appeal inadmissible.

The reasoning links cessation of the conduct relating to fumes to replacement of the existing water filtration with an activated carbon system. This was a finding for that installation: it does not demonstrate that a technology is universally sufficient. The decision provides no basis for transferring that solution to wood or charcoal flue gas. The operational lesson is the need to verify an intervention's actual effectiveness.

Before opening: a verifiable process

To organise discussion with the designer, installer and competent authorities, collect a file relevant to the premises. The following points are a working method to adapt to the obligations actually applicable:

1. Describe cooking appliances, energy supplies, processes and intended operating conditions.
2. Trace the effluent route from capture to terminal, indicating treatment and maintenance access.
3. Check the environmental regime and documents needed, together with the installation's territorial requirements.
4. Compare the design with the completed work; collect required declarations and annexes, manuals and component documents.
5. Document relevant checks and prepare a maintenance programme with records of interventions.

For an ETC supply, these data allow the requested system to be compared with the equipment's declared characteristics. The machine must be selected within the design. Treatment principles are explored in Particulate dynamics and flue gas thermodynamics; nuisance issues are discussed in Professional kitchen odours and the Court of Cassation.
