1996
• England lose to Germany in Euro semis• Environment Act 1995 in place; s57 inserted Part 2A into EPA
1990 – not yet in force• Avenue site seen as ripe for industrial redevelopment due to
good road and rail connections• Open cast coal mining seen as revenue stream to pay for
remediation• Environmental insurance wanted by the [private sector]

In a nutshell• Former Avenue Coking Works
• 240-acre brownfield site off Mill Lane, Wingerworth
• thought to be one of Europe's most contaminated locations
• £172.3million, funded largely by National Coalfields Programme
• 15 years remediation, now ready for redevelopment
• Outline planning permission for 469 houses
• By 2033: 1100 properties and ca 12 acres for business use
• Other facilities: new primary school, shops and sports & recreation facilities; cycleways and footpaths; wildlife habitats; green infrastructure; 7000 trees planted

Examining the role of value engineering
• Review panel (Ellis & Nathanail) report 12 December 2007• “The charge as seen by the authors for this report includes
the following questions:– Can the proposed ex situ thermal desorption and bioremediation
technologies treat the materials in the waste tip and lagoons?– Are there viable remediation alternatives to thermal treatment that
would fit within the EP / emda budget and would be implementable before the end of the National Coalfields Programme in March 2012?
– Is this project being managed and delivered effectively?”
“We recommend that emda and EP make absolutely certain that all site data, chemical analyses, original reports, historical records, computer graphic files, and interpretations are always in their hands. All original data bases should be stored on emda servers. Consultants and contractors should only be provided with duplicate copies of emda’s hard copy and electronic data.”

DQRA for Benzo(a)pyrene
• Justified criterion 50% higher than contractual generic criterion
• Enabled reuse of material
• Reduced importation of materials
• Reduced off site disposal of materials

The value of the independent advisor
• Critical friend• Objective advice• Apply innovation• Deliver cost cavings

Public projects as learning and research spaces
• Dissemination and knowledge transfer ought to be part of the contract
• Public funds should result in public knowledge
• emda / HCA & VSD were most generous in this regard
• PhD Projects• MSc projects• UG projects

Exploring public projects promoting UK expertise
• UK has a long track record of brownfield redevelopment
• Limited resources has created resourceful professionals
• Such skills are much needed around the world
• Avenue hosted visits I led from China, EU Common Forum and Iinternational Committee on Contaminated Land (ICCL), conference delegates, student groups– policy makers, practitioners, regulators

Conclusions
• Avenue took a long time & cost a lot• The time to judge its VFM is… 2033+• For now, the job is done… and lessons have
been learnt• OUR challenge is to apply that knowledge
elsewhere so it does not get wasted
