Consultation analysis
11. Benefits and impacts of de-designating SWPAs
There may also be some wider negative impacts of de-designation. While economically significant production of shellfish has not occurred in the last three years in the SWPAs proposed for de-designation, other activities taking place within these SWPAs would lose any potential benefits of being in an SWPA (See Benefits and impacts of new SWPA designations). This could include activities such as seaweed farming or production of other shellfish not considered as part of the current methodology.
There are potential benefits of the de-designation of SWPAs. For example, Scottish Water currently applies additional treatment, such as UV disinfection, to some wastewater treatment plants where it is found to be necessary to protect SWPAs. While the costs of this are likely modest, there are also carbon costs as UV treatment is energy intensive.
