16. 12 October 201416 Review of the Monitoring Programme This is the seventh year of the revised monitoring programme. The programme continues to work well with no significant omissions. Audited by EA/NII in February 2009 and EU (Article 35) in August 2011 – no major issues identified. A Best Available Techniques style review of the environmental monitoring programme completed in September 2011. –http://sellafieldsites.com/wp-content/uploads/2012/08/Environmental-Monitoring-BAT- Case-12-Dec-2011-for-website.pdfhttp://sellafieldsites.com/wp-content/uploads/2012/08/Environmental-Monitoring-BAT- Case-12-Dec-2011-for-website.pdf No changes to programme for 2014.

17. 12 October 201417 Summary Marine discharges remain at historic low levels. Concentrations of actinides in molluscs continue to decrease. The combination of decreasing concentrations and consumption rates has resulted in a further reduction of marine critical group dose, 130  Sv. Dose to terrestrial critical group remains well below 20  Sv. Doses below 1000  Sv dose limit for the general public. No Marking Required
