Armley asbestos disaster
The contamination was the result of the activities of a local asbestos factory, part of the Turner & Newall (T&N) group (often referred to by the name of its founders, J. W. Roberts Ltd.) and occurred between the end of the 19th century and 1959 when the factory eventually closed. At its peak the factory had 250 employees. At least 300 former employees are believed to have died from asbestos-related illnesses, and a number of cancer deaths in the Armley area were traced to the factory in 1988 as a result of an investigation by the "Yorkshire Evening Post". The estate was found to have the highest incidence in the country of mesothelioma. As the interval between exposure and diagnosis can be up to 50 years the number of further deaths which may occur due to the factory's emissions or residual dust since its closure cannot be predicted.
Spodden Valley asbestos controversy
The initial planning application was placed on hold in 2005, and Richard Butler, Principal Planning Officer for Rochdale Borough Council said in October 2008: "The application has not yet been determined and is suspended whilst the applicants and their consultants, together with our own contamination experts, assess a number of issues, the most important being the asbestos risk and the remediation required as part of the redevelopment." In December 2009, despite no decontamination work having been carried out, the council earmarked the site for 568 houses, based on a housing density of 30 dwellings per hectare, in a draft allocation of future brownfield land targets. In January 2010, however, the council deleted references to the redevelopment of the site. Rochdale parliamentary candidate Simon Danczuk warned that the council believe a housing development on the site is an inevitability and iterated that they are "sleepwalking into a catastrophic mistake." MMC have stated that "there is no viable alternative to development led remediation of the site." A National Health and Safety Commissioner who was formerly a Health and Safety Manager at the factory has said that the felling of trees and disturbing of soil on the site is "sheer madness... With the potential amount of asbestos on that site, no development should be built on this land." Hilda Palmer of the Greater Manchester Hazards Centre has said: "Asbestos is a carcinogen and it causes lung diseases. When asbestos gets into the air and can be inhaled by people it can cause those diseases 10, 20, 50 years down the line. So if there is any development on that site there is a potential for serious lung diseases, cancers and death from that development." Spokesman Jason Addy of Save Spodden Valley, stated: "The key issue is contamination. Asbestos from this site has killed far too many people already."
