What Paragraph 10 exemption permits

At the water treatment works where it was produced Paragraph 10 (1) allows the treatment of 10,000 cubic metres per year of:

  • listed sludges
  • waste water, and
  • bore-hole flushings.

It also allows the storage of these wastes at the site of production, prior to treatment provided:

  • the waste cannot escape, and
  • any unauthorised access to the waste is prevented.

Paragraph 10 also allows 100,000 cubic metres per year of the wastes listed in right hand column of the table and produced from the source alongside, to be recovered and stored within the curtilage of a sewage treatment works.

The wastes must be stored on a sealed surface with a collection sump which prevents wastes escaping except where this is permitted by other legislation.

Examples of activities that would not be suitable for registration under a Paragraph 10 exemption

A sewage treatment works wishes to treat septic tank sludge on an area of farmland outside the boundary of the sewage treatment works.
This activity would not be permitted under the terms of this exemption as it applies specifically to work undertaken within the boundary of the water or sewage treatment works.

A water treatment works wants to import sludge from other water treatment works for treatment.
This activity would not be allowed, as only sludge produced at the same water treatment works can be treated under this exemption. This is different to sewage treatment works who are allowed to take limited types of  waste from other sewage treatment works.
