New Drilling Rig in Action

STM is proud to announce that we have purchased a new Dando drilling rig

The new rig will enable us to complete more complex investigatory works, having been designed specifically for site investigation and environmental analysis. The rig has an ultra-small footprint and crawler mounted design to enable the user to carry out various sampling methods in confined spaces where access is limited.

The staff here at STM are all excited to begin using the new kit, which has already been utilized on some of our more recent site investigations.

STM assist IPPC Company Owner speed up Acquisition Transaction

STM were recently requested by an IPPC Company owner (Client) to undertake a Environmental Due Diligence Assessment (EDD) for their operational industrial site. The company, a very successful operational metal works, was due to be sold to foreign investors. The transaction had stalled due to the potential that the land may have been contaminated. As a result the purchaser was reluctant to take the next step.

Developer Successfully Appeals Contaminated Land Determination Notice

A developer recently successfully appealed against a Contaminated Land Determination Notice served on him by Walsall Council in respect of a gas works that had been redeveloped to housing in the 1970’s.

In only the second determination by the Secretary of State since the contaminated land regime came into force, this determination shows that Local Authorities need to follow the guidance to the letter when making determinations.

Brownfield registers finally underway

The framework for setting up the brownfield registers is now firmly in place. The Government recently enacted Regulation 3 of the Town and Country Planning (Brownfield Land Register) Regulations 2017 and published the associated  planning guidance.  In an effort to make development land more easily accessible, Local Authorities have been tasked with the job of maintaining registers of  Brownfield land that they consider to be appropriate for residential development. Local planning authorities (LPA) will be able to trigger a grant of permission in principle for residential development for sites in their registers giving developers and lenders more certainty in their development projects. LPAs need to publish these registers before 31 December 2017.

STM have developed the GeoEnviron Contaminated Land Management System which is essentially a Brownfield Register. Over 85 Local Authorities are  currently using the system. The system was designed to allow Contaminated Land Officers (CLOs) to collate and manage diverse information on previously developed land (land that may be contaminated). The system is fully integrated with GIS and includes a site prioritisation system to allow CLOs to decide which sites need to be further investigated as a matter of priority.

Having been developed over the last 15 years, we believe that the system is ideal for use as Brownfield Register. We will be running a webinar on the Thursday 7th September 2017 at 10.30am to provide an introduction to the system and its capabilities in relation to the Brownfield Registers. You can register for the webinar  using the following link:

X Marks the Spot

STM Environmental was recently approached by a local council to map out areas of potentially contaminated land within the local region. This project spanning a number of epochs ranging over 200 years involved sifting through old maps with a fine tooth comb in order to pick out sites of potential contamination, ranging from old industrial factories to more modern hospitals.

Giving Old Maps New Life

STM was recently approached by Hounslow Council to geo-rectify some aeiral maps of the council district. Hounslow provided a wealth of old aerial photo scans, taken from planes throughout the last few decades, with the task of mosaicking the images so that they alligned with Ordnance Survey MasterMap data.

Getting to know Hounslow from the skies over the years proved to be an interesting project, with well known sites being visible from the aerial photos, such as the old Twickenham Stadium, as shown below!
