CIV819 Management of Hazardous Wastes and Industrial Wastewaters

Contaminated Land Regime

• Objectives– to understand how the new ‘Contaminated Land

Regime’ provides a statutory framework for dealing with contaminated land

– to understand the responsibilities of polluters, land owners and the regulators

– to know how PPC will be used to control the future contamination of land

The Legacy

Parliamentary Office of

Science and Technology

1993

Expert Estimates:-• 50,000 to 100,000

potentially contaminated sites in UK

• 100,000 to 300,000 hectares

• (significantly less which pose risk to human health)

History of Contaminated Land PolicyUSA

– CERCLA 1980 (SUPERFUND)– SARA 1986

Netherlands– Soil Clean-up Act 1982– policy reversal 1987

UK– ICRCL 1976 (guidance)– EPA 1990 (STATUTORY LAW)– 1993 “consultation”– EA 1995 (STATUTORY LAW)– PPC Regulations (2000) (STATUTORY LAW)

Contaminated Land Regime

Environment Act 1995• Section 57 (EA 1995) inserts Part IIA into

the Environmental Protection Act 1990• Local Authority responsible• LA to formulate Strategy by mid-2002• LA actively identify contaminated sites &

cause them to be remediated

Definition

Contaminated land is any land which appears to be in such a condition, by reason of substances in, on or under that:

a) significant harm is being caused or there is significant possibility of such harm being caused: or

b) pollution of controlled water is being or is likely to be caused.

source “EPA 1990”

Page 8: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

Harm” is defined as:

“harm to the health of living organisms or other interference with ecological systems of which they form part, and in the case of man, includes harm to his property.”

source “EPA 1990”

Definition

Page 9: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

For a contamination to present a risk there must be:

• a potentially harmful Source• a pathway along which the contaminant can

travel.• a Receptor• a plausible Pollution Linkage.

EA 1995 Enforcement Responsibilities

Duties Tasks• Cause their area to be inspected

to identify Contaminated Land

• To determine whether a particular site is “contaminated”

• To Act as enforcing authority for contaminated sites (other than Special Sites)

• Establish responsibility for remediation.

• Determine what remediation is required and to ensure that it takes place.

• Arbitrate on the who bears what proportion of consequent liability.

• Record and maintain prescribed information in a Public Register.

Powers of Inspectors

Section 108 Environment Act 1995 :-• enter at any reasonable time• make any examination or investigation necessary• take photographs or samples• require the giving of information• order that premises or parts be left undisturbed

Page 12: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

12

EA 1995 Information and Inspection

L.A’s may derive information form a number of

sources to enable an assessment to be made

• Other Statutory Bodies

• Its own Land Use records

• Public Complaint

• Land Owners

Page 13: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

Prioritisation/Categorisation

• Part I AssessmentPreliminary prioritisation of sites

into groups for Part II Assessment

under the following headings.

• Development

• Surface Waters

• Groundwater

(This will comprise a desk top study

and can be carried out by

non- specialist personnel)

• Part II AssessmentSites in each group will be

categorised using individual risk

assessment

• Priority given first to group A

• Site information examined

• Site Visit

• Establish contaminants, pathway and risk

• Detailed exploratory survey where indicated

(Expert help will be required)

Appropriate Person

• CLASS “A”

Any person who

causes or knowingly

permitted contaminating

substances to be IN, ON

or UNDER the site

• CLASS “B”

Where reasonable enquiry

has failed to identify a

person fitting the definition

of “Class A”, the owner or

occupier of the land

If no Class A or Class B then site is an Orphan Site (ownership passes to LA)

Page 16: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

16

Appropriate Persons - Exclusions

• Class A – for abandoned mines• Class B - where pollution is to controlled water• Class B – for contaminants escaping to adjacent

land• Class B - when they act in official capacity e.g.

‘insolvency practitioners’, ‘official receiver’• Class A – where land was sold with ‘information’

regarding level of contamination

Apportionment of Liability

Inherited Problems

Contaminated land Adjoining Land

X Y

Contaminant

• “Person A” causes contamination of “Contaminated Land X”

• Innocent “Person B” becomes owner/occupier of “Contaminated Land X”

• “Person B” not liable to remediate “Adjoining Land Y” unless they had knowledge of the contamination at purchase (Caveat emptor)

migration

Page 18: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

Special SitesEnvironment Agency becomes the enforcing authority

after LA designates a site as a Special Site on the basis of:

• Water Pollution Cases– Controlled water used for Drinking Water abstraction– Ecologically important sites (SSSI, reserves)– Major Aquifers

• Industrial Cases– Pollution from sites involving Acid tar, Oil, Explosives,

and Nuclear (excludes coal processing)

• Defence Cases– Army, Navy, Airforce, Weapons Testing sites

Extends to contaminated sites adjacent to above cases

EA 1995 Remediation Notices

Where Pollution Linkage is confirmedRemediation Notice served on each “appropriate person”

• Can cover assessing site condition (detailed intrusive Site Investigation), preventative works, remediation and monitoring

• Must be “reasonable” having regard to cost and seriousness of harm/pollution

• Must be preceded by consultation

Page 20: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

20

Non-Compliance withRemediation Notice

• Enforcing Authority can carry out the remediation and recover costs.

• Non-compliance is a criminal offence punishable by imposition of a fine of up to £20,000 plus £2,000 a day.

Page 21: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

21

Recovery of Costs

Local Authorities must take into account:

• HARDSHIP

LA must consider any hardship that may be caused.

• BUSINESS CLOSURE OR INSOLVENCY

Where remediation costs would make a business insolvent, the authority should consider a reduction in costs. The main aim is to recover as much cost as possible without causing insolvency.

Page 22: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

22

EA 1995 Public Registers

Will be maintained to include:

• Remediation notices and appeals.

• Remediation work carried out following a remediation notice.

• Conviction for offences.

Page 23: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

23

“Suitable for Use” (risk based)• Remediation to a standard appropriate for the intended

end-use of the site

“Multi-functionality”• Remediation to prescribed standards allowing every

potential type of end-use.

“Original Condition”• PPC regulations

Remedial Targets

EA 1995 Conclusion

• CL Regime brought into force 2000.

• Local Authorities publish Strategy 2002

• New regime extremely complex and bureaucratic

• Lack of significant new resources

• Responsibility for “orphan sites”

Page 25: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

25

Pollution Prevention & Control (PPC) Regulations 2000

• IPPC Directive (96/61/EC)– enacted in UK as “The Pollution Prevention

and Control (England and Wales) Regulations 2000”

– Contaminated land covered under requirements for ‘Site Reports’

– Regulator is ‘Environment Agency’

Page 26: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

26

Pollution Prevention & Control (PPC) Regulations 2000

Principle of PPC• Specific Industrial Sectors are regulated

• Aim to preserve land quality rather than deal with Historic pollution (i.e. stop future pollution)

• Linked to Permit Application– authorises the site (or installation) to conduct specified industrial activity

• Process requires ‘Site Report’ – a detailed investigation of current state of the land that acts as a ‘baseline’

• Closure of Site (or Change of Use)– Cessation Site Report compared with Original Site Report– Site must be remediated to ORIGINAL CONDITION (defined by first Site

Report) and not ‘Suitable for use’

Page 27: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

27

Pollution Prevention & Control (PPC) Regulations 2000

• Purpose of a Site Report– To document the condition of the site with particular reference to

substances in, on or under the land that may constitute a pollution risk– All land of the installation is covered

• Phased approach– 1a Desk Study (Conceptual Model)– 1b Further Desk Study and Exploratory Investigations– 2 Main Intrusive Investigation– Complex activities may be zoned– Technical Content

• presentation of lateral and vertical distribution of contaminants

• Site Report sent to LA (as statutory consultee)– Data can be used by LA under Part IIA EA 1995 legislation

Page 28: CIV819 Management of Hazardous Wastes and  Industrial Wastewaters Contaminated Land Regime

28

Other Statutory Law

Water Resources Act (1991)

• Section 85

– criminal offence to “cause or knowingly permit any poisonous, noxious or polluting matter to enter any controlled waters”

– conviction of an offence can incur 3 months imprisonment or up to £20,000 fine

• Section 161

– To prevent polluting matter from entering controlled waters

– To remove or dispose of polluting matter from controlled waters

– To restore waters to their state immediately before the pollution event (as far as is practicable)

– Works notices can be served by EA

• EA can claim costs when pollution enters, or is likely to enter, any controlled water
