LNAPL Illustrated Handbook is Now Available

CL:AIRE is delighted to announce the publication of the “LNAPL illustrated handbook”, entitled Illustrated handbook of LNAPL transport and fate in the subsurface

The LNAPL illustrated handbook presents best-practice guidance for the assessment and remediation of light non-aqueous phase liquids (LNAPLs) in the subsurface. LNAPLs notably include fuels and oils, for example petrol (gasoline), diesel and heating oils, and are amongst the most commonly encountered organic contaminants in the subsurface environment due to their ubiquitous use, accidental release and, perhaps, poor (historical) disposal. Central to the handbook and the management of risks posed is the development of conceptual models of LNAPL behaviour in common hydrogeological systems.

The LNAPL illustrated handbook provides a blend of technical detail and real world conceptualisation of the LNAPL problem and appropriate methods to investigate and manage it. The handbook also facilitates access to a wealth of detailed research, guidance and case study literature within the various topics covered. It will be useful to the practitioner and research communities, and also provide a valuable educational resource to others having a less direct interest or specialised knowledge.

The LNAPL illustrated handbook has been written by the following authors - Derek Tomlinson (Geosyntec Consultants), Steven Thornton (University of Sheffield), Alan Thomas (ERM), Stephen Leharne (University of Greenwich) and Gary Wealthall (Geosyntec Consultants) - and edited by Michael Rivett (University of Birmingham).

The production of the LNAPL illustrated handbook was funded by Shell Global Solutions (UK) and supported by the Environment Agency.

The LNAPL illustrated handbook can be downloaded for free at www.claire.co.uk/LNAPL (PDF 17MB)

Land Forum Update

The latest Land Forum notes of the meeting held on the 25th November 2014 have been uploaded onto the dedicated web page www.claire.co.uk/landforum. Also uploaded are two draft papers detailing the National Quality Mark Scheme (NQMS) and Suitably Qualified Person (SQP) Declaration that were discussed at the meeting. To access the notes of the meeting and the papers please follow the links.

The National Quality Mark Scheme is an ongoing Land Forum initiative and the Land Forum - professional standards sub-group has been actioned to scope up further the National Quality Mark and role of an SQP.  The sub-group will be doing this before the next Land Forum meeting and further information will be made available as soon as possible.  The next Land Forum meeting will be held at the end of January 2015.

C4SL news

Defra has published an erratum for the C4SL project and this can be seen on the SP1010 project page. On this occasion they have made the amendments to the project documentation as well as detailing them within the erratum.

Following three successful training courses on understanding the use of the C4SLs, CL:AIRE is looking to organise a further three events in London, Manchester and Birmingham.  Dates will be announced in the New Year.

Environment Agency: New and Revised Standard Rules Permit - Public Consultation

A public consultation has recently been announced by the Environment Agency (EA) on new and revised standard rules permits. Readers may be particularly interested in the changes being proposed for recovery permits and soil recycling activities including via mobile plant.  

The EA is asking for views on new and revised rule sets and risk assessments, as summarised below:

  1. Standard rules allow a range of wastes to be used in construction and land reclamation activities. It has identified a risk to groundwater from some of these waste types in some locations. It is proposing the withdrawal of these existing standard rules and replacing them with a single set of rules which will be more restrictive as to the type of waste permissible and location at which they can be adopted. The changes it is proposing will better protect groundwater quality.
  2. It is proposing the revision of standard rules covering land spreading and digestate storage. The changes introduce restrictions affecting land spreading and storage activities which will give better environmental protection. There are also new provisions giving operators greater flexibility in the size of area and choice of acceptable wastes they can spread. The EA is further taking this opportunity to make minor changes to definitions and wording to improve clarity and consistency.
  3. It is proposing three major changes to 13 standard rules permits covering soils recycling activities. The changes are:
  4. Additional advisory text on the need to meet end of waste status for recovered materials
  5. The modification of waste acceptance procedures for soils from known or suspected contaminated sites
  6. The clarification of authorised treatment activities for mobile plant permits for the treatment of soils, materials and products to allow simple segregation and sorting activities as a standalone as well as associated recovery activity.

The consultation closes on 20th March 2015.  To access the consultation please follow the link:

Metal Mine Treatment – Tender Opportunity

The Coal Authority and Environment Agency are working together to clean up pollution from abandoned metal mines in England. They require assistance in identifying treatment technologies that are effective for metals such as cadmium, zinc, copper and lead, and ideally have low operating costs. The Coal Authority has just published an open tender to identify a number of different experts who will be able to provide treatment advice on a range of different metal mine water chemistries and flows.

If you would be interested in submitting a tender, please visit the Coal Authority’s eTender portal, and look at the ‘current opportunities & notices’ section. You will need to register first (free). The closing date for tender submissions is 28 January 2015.

Draft International Standards for Public Comment

The following Draft International Standards (DISs) have been issued for public comment:

  •     ISO/DIS 18400-101 Sampling plan
  •     ISO/DIS 18400-102 Selection and application of sampling techniques
  •     ISO/DIS 18400-103 Safety
  •     ISO/DIS 18400-105 Transport, packaging etc.
  •     ISO/DIS 18400-106 Quality assurance
  •     ISO/DIS 18400-107 Reporting
  •     ISO/DIS 18400-201 Pretreatment in the field

Those shown in bold WILL be adopted as British Standards as they are direct replacements for ISO 10381 series standards that are normative in BS 10175.

Definition of Waste: Development Industry Code of Practice 2015 Training Dates

The training course is based on Version 2 of the Definition of Waste: Development Industry Code of Practice (DoWCoP) and will explain in detail how the various scenarios for material reuse are dealt with, the operational boundaries and interaction with other industry initiatives. Upon completion of the course delegates will be confident to use, or work alongside the DoWCoP.

Venues to be advised.

DoW CoP London and the South East Report

The Environment Agency and CL:AIRE undertook research to provide an analysis of the Definition of Waste: Development Industry Code of Practice (DoW CoP) use in London and the South East. The project focused on the impact the use of the DoW CoP is having on materials reuse and sustainable remediation of brownfield land in London and the South East.

The objectives of the research were to show how the DoW CoP is contributing to:-

  • more brownfield land being reused;
  • resources being managed more sustainably;
  • use of more sustainable remediation practices; and
  • carbon reductions.

The project was split into two phases; the first phase consisted of an audit of 32 projects in London and the South East. The main aim of Phase 1 was to show that the DoW CoP is contributing to more land being reused.

Phase 1 was also used to:-

  • Gain information to demonstrate that the DoW CoP is being applied as it is intended;
  • Identify where the DoW CoP could be improved; and
  • Encourage development of future work.

In the second phase, basic sustainability assessments were undertaken comparing material management using the DoW CoP with an alternative option (Dig & Dump). Three projects which were audited in the first phase were selected for the Phase 2 sustainability assessment. Each of these projects fell under a separate DoW CoP scenario (Site of Origin, Direct Transfer and Cluster).
