CASE STUDY ONIED BASELINE REPORT

BREAKOUT SESSION ON NICOLE SPRING WORKSHOP IN BERLIN,

2014, MAI 16TH, HORST HERZOG, INFRASERV

CASE STUDY ON BASELINE REPORT IED

TASKS FOR CASE STUDY

21.05.2014 Infraserv Frankfurt/Main, Horst Herzog, Waste and Remediation Management

1. Design an approach for a Baseline Report

2. Please devide into 2x3 groups and focus on following 3 items:

• Team 1: What should be the contet of the Baseline Report? How many exploration pointsare necessary and where shoud they be placed? Are soil and / or groundwater analysisnecessary? If Yes – How many samples and which substances should be analyzed?

• Team 2: Which monitoring of the operation should be implemented? Which substances areof interest? Consider the historical pollution unter the site and the hydraulic barrier. Keep in mindthe possibility of a substance to be used as a indicator for pollution in 20 years! Can organizational standards of the crew or certifications be considered?

• Team 3: Use of Baseline Report at site closure? How to integrate IED requirements and usual remediation practices based on risk management? Is there a conflict between implementing a risk assessment and the direct comparison of concentrations / pollutant charges? How to consider monitoring information? Take into account the relevance of notifications of local authorities, agreements under public law or constructional characteristics.

Time: Team work: 09:30 – 10:15 Collect findings in groups: 10:15 – 10:30Presentation of resuts in plenum: 10:30 – 11:00

PLANT IS LOCATED ON A HUGE CHEMICAL INDUSTRIALSITE, 1.100 ACRES (4,6 KM²)

21.05.2014 Infraserv Frankfurt/Main, Horst Herzog, Waste and Remediation Management 3


UNTIL 1960 FLOODING PROTECTION AND SITE LEVELING WAS ACHIEVED BYFILLING-UP THE SITE WITH WASTE – FROM BUILDING DEMOLITION ANDCHEMICAL PRODUCTION



NORTH SITE, AREA 575 ACRES, INDUSTRIAL USE SINCE 1868


• complete landfill, increasing height from the north rim towards the river from 1 to 12 m, average height 4,5 m; totally 21 Mio. t landfill

• partly heavy contamination of the soil below the filling down to 35 m depth

• heavy contamination by mainly

• several thousand t heavy metals, e.g. chromium and lead

• 1-2 thousand t arsenic

• about 5 thousand t of chlorinated hydrocarbons, aromates, aniline derivates etc.

• other production residues (lime pits, building demolation etc.)

• heterogeneous distribution of all contaminants

• Heavy historical groundwater contamination with increasing concentration toward the river Main

• 1st groundwater level 6-12 m below ground level

• 2nd groundwater level 14-20 m below ground level

• 3rd groundwater level 26-32 m below ground level


CORE ELEMENT OF THE SITE REMEDIATION CONCEPT: THE GROUNDWATER IS CAPTURED BY REMEDIATION WELLS(2.5 MILL. M³/YR)

Southern site(10 wells)

Northern site(24 wells)

HISTORICAL POLLUTION OF GROUNDWATER AND SOILUNTER THE PLANT


Exemplaric concentrations in soil (original sustance and leachate)


HISTORICAL POLLUTION OF GROUNDWATER AND SOILUNTER THE PLANT


Exemplaricconcentrations in groundwater


FRAME: ONGOING REMEDIATION ON INDUSTRIAL SITE

• Complete capture of the groundwater by hydraulic barrier (remediation wells)

• Reduction of contaminations by removal of hot spots if commensurate

• Recycling of former production areas for new building areas (total soil exchange as exception)

• Investigational program for soil, soil-air and groundwater

• All this is based on three General frame directives by order of local authorities, giving Investors certainty (not to have to start additional local remediation activities)

• Each Investor / Lesee gets a description of the pollution situation (soil/groundwater) of hissite

GROUNDWATER UNDER PLANT IS CAPTURED BY2 REMEDIATION WELLS (16N1 AND 17N1)

GW-capture areasArea of interest


NEW PROJECT: PLANNED ENLARGEMENT OF AN EXISTING PLANT WHICH DETERMINS A NEW PERMIT

• Construction of new storage tanks for acetic acid and vinyl acetate in enlargement of an existing plant

• Due to this, a complete Baseline Report is necessary – for both parts of the plant: newtanks ans old production plant

• Product called M* in Presentation is solid, a basic product for plastics / synthetic materials

• 10 additional Substances are listed in the application for production permit

• Plant is surrounded by pipeline bridges

• Area:

• Existing Plant 11.000 m²

• New Tanks: 4.000 m²

• Planned foundation: Excavation ´till 3,5 m under ground level and piling

• Special constructional protection devices(German VAwS)? Yes – see Plan on next pages
