Emamectin benzoate (EmBz) - environmental quality standard (EQS) - implementation: consultation

Sets out our directions to the Scottish Environmental Protection Agency (SEPA) on the application of a new environmental quality standard (EQS) for Emamectin benzoate (EmBz). We are seeking views on the timescale SEPA should implement to apply the new EQS reducing the discharge limits for these farms.


Implementation of the new proposed emamectin benzoate EQS

SEPA has to make decisions on applications for new or increased discharges of EmBz. SEPA also make proposals to change the location at which authorised discharges take place (i.e. proposals to relocate fish pens).

SEPA makes these decisions based on the best available science on risk to the water environment., As is appropriate, SEPA will apply UKTAG's recommended EQS to protect the water environment against deterioration. SEPA will apply the new EQS to previously authorised discharges once Scottish Ministers provide directions to do so.

Fish production cycles at sea can last up to around 24 months. In identifying the appropriate timescale for applying the new EQS to existing discharges, we consider basing the implementation timescale on a production cycle, or multiple thereof. This is likely to be the best fit with planning and investment horizons across multiple operators.

Taking this approach, we would like your feedback on what would be the appropriate timetable that provides marine finfish farm operators with a reasonable period to make any required adjustments to meet the new EQS standards but that does not unduly delay improvement in the quality of Scotland's coastal waters.
