Agenda

SLIDE 3

Sediment Pollution

Sediment pollution costs $16bn in environmental damage annually and is the most common pollutant affecting watercourses.

EPA, USA, 2018 Factsheet

In Australia – the effect of sediment on the Great Barrier Reef… $8.2 bn as clean up costs

Environmental Legislative Evolution

SLIDE 5

Environmental Legislations

5 Maturing to Tangible IA on Construction Projects #IAIA19

Universal Principles:

Stakeholder Consultation
Impact Identification
Impact Assessment
Mitigation Measures

NSW, Australia Environmental Planning and Assessment Act, 1979 (Act No. 203 of 1979) (“EPA Act”) South Africa National Environmental Management Act, 1998 (Act No. 107 of 1998) (“NEMA”)

Small-scale Road Project

NSW, Australia

Roads & Maritime Services

(RMS)

Environmental team within RMS

does environmental assessment “fullest extent possible” (using EIS / REF)

RMS is a determining authority,

as delegated by the EPA Act sharing responsibility

Does not overburden the EPA

South Africa

South African National Roads

Agency Limited (SANRAL)

Independent Consultant

appointed for BA / EIA

SANRAL cannot make

environmental decisions as responsibility and jurisdiction with DEA

SLIDE 7

What are the results of such an evolution?

7 Maturing to Tangible IA on Construction Projects #IAIA19

Shared determining authority model One environmental authority model

Focus on infrastructure delivery while considering environmental matters
Responsible and capable environmental team
Unsuccessful if subjected to corruption and sub-standard assessment

SLIDE 8

Environmental Culture on a Construction Site

SLIDE 9

Large-scale Project Small-scale Project

Type of culture to be tolerated and encouraged with a focus on:

Communication
Safety standards
Methodology of construction
Contractual obligations
Project team
Environmental risks

Type of culture to be tolerated and encouraged with a focus on:

Communication
Safety standards
Methodology of construction
Contractual obligations
Project team
Environmental risks

SLIDE 10

Low Environmental Risk → High Environmental Impact

SLIDE 14

1. As the ‘one environmental authority model’ in South Africa

evolves and matures, could elements from the ‘shared determining authority model’ of NSW be considered?

2. Environmental representative to advise on small-scale

construction projects to help the PM / Engineer manage environmental risks.

3. ESCP for tangible and prompt environmental risk management,

even on small-scale construction projects.
