Are house prices in Welshpool expected to be affected in a negative way, should the application be accepted?

A study undertaken by Cranfield University on Assessing the perception and reality of arguments against thermal waste treatment plants in terms of property prices (K.J.O Phillips et al)concluded that the perceived negative effect of the thermal processing of waste on local property values is negligible. 

This study considered a number of Energy from Waste facilities in the UK which had been operational for at least 7 years.  Property sales data within 5km of the sites was acquired and analised.  The local property sale prices were compared before and after the facilities became operational. The study concluded “No significant negative effect was observed on property prices at any distance within 5 km from a modern operational incinerator. This indicated that the perceived negative effect of the thermal processing of waste on local property values is negligible”.
