  • the interests of users of the water environment, resulting from the proposed discharge of:
    • Organic matter;
    • Medicine residues;
    • Other chemical emissions.


How we will manage responses

At the end of the consultation, we will publish all comments. You can tell us within the consultation if you do not want your comment published. If this is the case, we will publish a note saying that we received a response but have not made it publicly available.

We will write to everyone who responded to the consultation and provided contact details, outlining the feedback received, how it has been taken into account and our proposed decision.  If you disagree with our decision, you will be given the opportunity to request that Scottish Ministers ‘call-in’ the application for their determination.

Scottish Minister may agree to call-in an application if: 

  • The representation provides clear reason for the objection, supported by evidence, and
  • The objection relates to material considerations raised during determination of the application.

The full criteria for Ministerial consideration are listed on

The final decision will be published on this website along with the authorisation, if granted.

What happens next

SEPA issued a letter outling the proposed determination to everyone who made a representation on 28 March 2024, providing these people with the opportunity to notify Scottish Ministers of any objections to the decision.

Scottish Ministers received objections to the proposed determination and SEPA await confirmation as to whether Scottish Ministers intend to call in the application for their determination.
