Ultimo aggiornamento: Nov. 26, 2025

The impact assessment (VIncA) - as reported on the website of the Piedmont Region - is the administrative procedure, of a preventive nature, which must be submitted to any intervention, plan or project that could have significant impacts on a site or proposed site of the Natura 2000 network, individually or jointly with other plans and projects, taking into account the conservation objectives of the site itself (pursuant to Directive 92/43/EEC “Habitats” and D.P.R. 357/97).

This procedure applies to general or sectoral plans, projects and interventions whose effects fall within the sites of the Natura 2000 network, in order to verify the possibility that the planned interventions, taken individually or jointly with others, may cause significant negative impacts on a Natura 2000 site, taking into account the conservation objectives of the same.

The VIncA in Piedmont is regulated by the regional law of June 29, 2009, n.19 “Consolidated text on the protection of natural areas and biodiversity” and by the National Guidelines for Impact Assessment (VIncA) - Directive 92/43/EEC "HABITAT" Article 6, paragraphs 3 and 4, implemented by the Piedmont Region with the D.G.R. 55-7222/2023/XI of July 12, 2023.

According to current regulations, the assessment of subjectivity to VIncA is no longer possible; therefore, all Plans, Programs, Projects, Interventions or Activities (hereinafter referred to as P/P/P/I/A), including manifestations and events, that fall entirely or partially within a Natura 2000 Site or that could have indirect impacts on it must be subjected to the Impact Assessment.

The VIncA process is divided into 3 levels called: Screening (Level I), Appropriate Assessment (Level II), and Derogation to Article 6.3 of Directive 92/43/EEC "Habitats" (Level III).

Level I: Screening

Identification process of the potential implications of a P/P/P/I/A on a Natura 2000 site or multiple sites individually or collectively with other P/P/P/I/A and determination of the possible degree of significance of such impacts.

For specific verification formats, correspondence assessment formats, and screening formats, please refer to the dedicated page: link.

Level II: Appropriate Assessment

Identification of the impact of the plan or project on the integrity of the Site/Sites, individually or together with other P/P/P/Is, taking into account the structure and function of the Site/Sites, as well as its conservation objectives.

For specific, appropriate VINCA level 2 specifications, please refer to the following link.

VInCa è l'applicazione web che consente a cittadini, professionisti, enti e soggetti proponenti di presentare all'Ente una nuova istanza, relativamente alla richiesta di Screening (livello I) o di Valutazione Appropriata (livello II) tramite una proceduta guidata passo a passo, facilitando la composizione e la trasmissione della documentazione all'Ente.

Livello III: deroga all'articolo 6.3 della Direttiva 92/43/CEE "Habitat"

Questa fase viene attivata in caso di incidenza negativa, che permane nonostante le misure di mitigazione definite nella valutazione di incidenza appropriata (livello II), e dopo aver esaminato e valutato tutte le possibili soluzioni alternative del P/P/P/I/A, compresa l'opzione zero, qualora si sia in presenza di motivi imperativi di rilevante interesse pubblico opportunamente motivati e documentati (IROPI - Imperative Reasons Of Over Reeding Public Interest). In questo livello si valuta la sussistenza dei motivi imperativi di rilevante interesse pubblico, che consentirebbero in deroga ai disposti dell'articolo sei della direttiva habitat di realizzare comunque un P/P/P/I/A attuando però preliminarmente ogni necessaria misura di compensazione atta a garantire comunque gli obiettivi di conservazione dei siti e la coerenza della rete Natura 2000.
