Dear Alan, 
 
Request for Information under the Environmental Information Regulations 2004 
 
Further to my letter of 26 July 2013, I am now in a position to provide you with a 
substantive response to your request for information regarding nuclear waste disposal at 
Chatham Docks.   
 
As I confirmed in my letter of 9 July, we do hold information that falls within the scope of 
your request.  I also stated that EIR exception 12(5)(a) (national security, international 
relations and defence) may apply to the information you have requested.  Following a 
detailed review, this exception is not considered to apply.  I shall therefore address each of 
your questions in turn: 
 
Q1. 
I would like to know if there is currently any monitoring taking place of the 
nuclear waste disposed of at Chatham Docks in Pier Road, Gillingham. 
 
Our records show that six monthly routine radiological monitoring is carried out at the 
disposal site within the wooded area adjacent to Pier Road, Chatham. This schedule was 
agreed with the then regulator, Her Majesty‚Äôs Inspectorate of Pollution, (now part of the 
Environment Agency) in 1996. This monitoring comprises groundwater sampling and the 
measurement of surface gamma dose rates in the area.  
 
There is currently no specific Carbon-14 monitoring undertaken of the waste at Chatham.  
 
Q2. 
I would also like to know if any work has been undertaken to ascertain 
whether Carbon-14 is present in the waste.  
 
Our records show that work was conducted in 2000 to determine the quantities of Carbon-
14 transferred to the British Nuclear Fuels Limited site near Drigg, Cumbria.  This work 
considered the total predicted production of Carbon-14 from the Naval Nuclear Propulsion 
Programme.   
 
 
 
 
 


 
Q3. 
If this is the case, I would like details of the work, the levels of Carbon 14 
detected (if indeed there is any) and what the current situation is. 
 
Although not a specific study of the Pier Road, Chatham Docks site, this work indicates 
that the waste disposed of at that site contains up to a maximum of 0.95 GBq of Carbon-
14.  
 
The value of 0.95 GBq of Carbon-14 has been calculated using a methodology known as 
Mass Balance Hypothesis, which is based on the amount of Hard Trash and Compactable 
Wastes disposed of from the Naval Nuclear Propulsion Programme. 
 
If you are not satisfied with this response or wish to complain about any aspect of the 
handling of your request, then you should contact me in the first instance. If informal 
resolution is not possible and you are still dissatisfied then you may apply for an 
independent internal review by contacting the Deputy Chief Information Officer, 2nd Floor, 
MOD Main Building, Whitehall, SW1A 2HB (e-mail [email address]). Please note that 
any request for an internal review must be made within 40 working days of the date on 
which the attempt to reach informal resolution has come to an end. 
 
If you remain dissatisfied following an internal review, you may take your complaint to the 
Information Commissioner under the provisions of Section 50 of the Freedom of 
Information Act. Please note that the Information Commissioner will not investigate your 
case until the MOD internal review process has been completed. Further details of the role 
and powers of the Information Commissioner can be found on the Commissioner's 
website, http://www.ico.gov.uk
 
Yours sincerely,
