Synopsis:

In order to demonstrate that after the development the site could not be classified as ‘contaminated land’ under Part 2A of the Environmental Protection Act a Phase I desk study report was required to support the application for residential redevelopment f the site.

A desk study determines what issues relating to historical contamination may affect the site, this is undertaken by reviewing the site history using a combination of O.S. maps, aerial, plates and street level imagery, a review of data held by regulatory bodies (Environment Agency, local authority, BGS etc.) as well as a site walkover survey.

The history of the site and surrounds were researched using a combination of Ordnance Survey (O.S.) maps, street level imagery and aerial plates, this revealed the site initially developed between 1876 and 1898 when ‘Birchall Lodge’ was present on the site, by 1992 the site had been redeveloped and was occupied by a public house. Street level imagery indicated the business closed between 2012 and 2017.

The planning history of the site was reviewed as part of the desk based research and reports associated with any previous application were located and studied, no salient information was obtained.

The published geological maps identified the site as being in an area where the bedrock (Pennine Middle Coal Measures Formation) was exposed at the surface. The geological maps identified made ground on the southern boundary of the site. The borehole section sheets published by the BGS were reviewed and a borehole on the south eastern boundary weas available,

Information. Obtained from the Coal Authority indicated the site was within a ‘Development High Risk Area’, this revealed a thin layer of drift soils (1.7mbgl) underlain by siltstone.

Data provided by regulatory bodies confirmed the presence the a number of pits and a sewage works within 250m of the site as well as a tank on the site and opencast workings on the site boundaries..

On completion of the desk based research a site reconnaissance visit was undertaken in order to obtain further information on the potential sources identified in the desk based research and to identify any other potential sources. The walkover survey confirmed the site was occupied by a former public house with associated parking and landscaped areas as well as open land.

Once the walkover survey was completed a qualitative risk assessment was undertaken on the potential sources of contamination identified in the desk study report in order to determine if any warranted further investigation, this concluded that the potential for made ground to be present on the site as well as the risk of gas generation from the in-filled open cast workings and possible shallow worked seams further works were proposed.

The report was submitted to support the application and can be accessed via the planning portal.

 

 

The recommendations of the report were accepted and the condition was discharged pending the completion of the remediation.
