The integrated environmental permit (AIA) is necessary for carrying out any installations in which one or more activities listed in annex VIII to part two of Legislative Decree 152/2006 are performed.
The AIA also replaces the environmental permits listed in annex IX to part two of Legislative Decree 152/06 necessary to carry out the activities performed and the facilities present at the installation.
The authorisation procedure requires the convening of a local authorities planning conference, to which the relevant authorities on environmental matters are invited, along with the applicant for the permit.
The Single Environmental Permit (AUA) is an environmental authorisational measure which uses a single licence to replace various environmental permits provided for by the sectoral legislation.
The AUA must be requested by small and medium-sized enterprises (as defined by Ministerial Decree on Production Activities of 18 April 2005 in art. 2) and by establishments not subject to the discipline of the AIA (Integrated Environmental Permit) which are subject to the issuance, establishment, renewal or updating of at least one of the qualifying environmental permits (atmospheric emissions, water discharges, etc.).
Equipment and activities that produce atmospheric emissions must receive prior authorisation aimed at preventing and limiting atmospheric pollution, in accordance with the provisions of part five of Legislative Decree 152/2006 and subsequent amendments and additions.
Some types of equipment and activities (included in part I of annex IV of part five) have atmospheric emissions which the legislator has deemed nearly irrelevant to the effects of atmospheric pollution: the facilities in which only these types are present are not subject to authorisation.
For the specific categories of facility (included in part II of annex IV of part five), the legislator has determined that the regions may adopt general authorisations which can be joined by way of simplified authorisation procedures.
For all other facilities which do not belong to the two aforementioned exceptions, a permit for atmospheric emissions must be requested by initiating an ordinary authorisational procedure which other relevant entities (the city, ARPA) may participate in, which can provide for the institution of the local authorities planning conference and which is concluded with a document released by the relevant authority.
All discharges of industrial waste waters must be authorised in advance as provided for by art. 124 of Legislative Decree 152/2006 and subsequent amendments and additions. Art. 74 defines industrial discharge, i.e. industrial waste water, as “any type of waste water discharged from buildings or facilities where commercial activities or the production of goods takes place, other than domestic waste water and run-off rainwater”.
