1 INTRODUCTION

NCC Environmental Services (Pty) Ltd (hereafter referred to as the “NCC”) were appointed by Saldanha Bay

Municipality (Hereafter referred to as the “SBM”) to conduct an external audit in terms of compliance with

the conditions stipulated in the Section 30A Directive, including an approved Environmental Management

Programme (EMPr), issued as part of its Water Resilience Projects located within the boundaries of the

Saldanha Bay Municipality.

This audit focuses on the Langebaan Road Well field intervention only and aims to address Condition 6.3 of

the issued Section 30A Directive which states:

‘The municipality must submit audit reports (per measures or intervention to be implemented)

to this Department for the commenting purposes and acceptance. Copies of these audit reports

must also be submitted to the Department of Water and Sanitation, Heritage Western Cape, and

the Department of Environmental Affairs: Oceans and Coasts for record purposes.’

The direction further outlines requirements for each audit type in Condition 6.3.1.1 and Condition

6.3.1.2

After discussions with the Department of Environmental Affairs and Development Planning (DEADP) it

was understood that the audit required for Condition 6.3.1.1 has been completed and submitted to the

Department in the form of the ECO close out report therefore only a report required for Condition

6.3.1.2 will be compiled.

The requirements include:

‘A second audit report within three (3) months of completion of an emergency measure or

intervention (per measure or intervention). This second audit report must inter alia confirm how

the measures or interventions implemented have contributed to the addressing the current

water supply emergency situation and improved the water supply security in the areas within the

jurisdiction of the municipality. This second audit report must also detail how all environmental

impacts associated with each measure or intervention implemented have been mitigated’

A site visit was conducted on the 1st July 2020 after which a report was compiled and serves to document the

External Audit proceedings, and is a record of all observations, recommendations and conclusions made during

the engagement.


1.1 Audit Scope and Purpose

Although SBM have been exempted from having to acquire an Environmental Authorisation they were

required to produce a Generic Environmental Management Programme (EMPr) in compliance with Section

24N of NEMA requirements.

In accordance to Regulation 34 of the NEMA: EIA Regulations, 2017, as amended, the holder of an

authorisation1 must, for the period during which the environmental authorisation and EMPr, and where

applicable the closure plan, remain valid—

a) Ensure that the compliance with the conditions of the environmental authorisation and the EMPr, and

where applicable the closure plan, is audited; and

b) Submit an environmental audit report to the relevant competent authority.

As such, the scope of the environmental audit report will be based on assessing the conditions of the EMPr,

and where applicable, the closure plan. The Section 30A Directive will also be considered for this audit.

The purpose of the environmental audit is to address the legal requirements to report on the level of

compliance with above mentioned conditions, report on the objectives and outcomes of EMPr and the extent

to which it were achieved. In addition, any new impacts or risks will be assessed, the effectiveness of the EMPr

will be evaluated, and shortcomings or any changes in the EMPr identified.

1 Not applicable for this audit as a result of the Section 30A Directive issued


2 BACKGROUND

2.1 Project Background

On average the municipality uses 37ML of water per day, this includes all domestic and commercial users. The

current usage allocation is approximately 60% Industrial vs 40% domestic. Restrictions put in place showed a

significant reduction in daily consumption. Restriction measure continue, to further reduce consumption.

More interventions were however required to ensure sustainability of SBM supply

During the droughts which the Western Cape suffered from SBM implemented various water augmentation

projects. As part of the interventions the Langebaan Road and Hopefield well fields were established. Both

well fields formed part of the Municipalities Water Intervention Plan (WIP) and was approved with a Section

30A directive. Both projects have been implemented in totality with an Environmental Control Officer (ECO)

forming part of the project team. The ECO compiled monthly reports and a Final Closure report.

Section 6.3.1.2 of the section 30A Directive requires a second audit within 3 months of completion of an

emergency intervention.

The Langebaan Wellfield, traditionally referred to as Langebaan Phase 1, was completed in October 2018 and

involved the addition of four (4) boreholes to an existing four (4) borehole network. This existing system feeds

in to bulk water system originating from the Berg River.

Supply from Western Cape Water Supply System (WCWSS) with its abstraction point being Misverstand dam

was 20 427 000 mᵌ/a prior to the interventions. SBM had to aim to reduce demand to 20.35 ML/day during

level 6 water restrictions which was deemed impossible without major economic damage, due to business and

industry being the SBM’s biggest consumers. Before the drought SBM was utilising 37ML/day which was

already above the previous allocation before the increased allocation figure above

Where possible existing farm roads were utilized to ensure minimal impact on vegetation.

Only Borehole 4 required a new access route in order to gain access.

The Contractor used a portion of the landowner’s property as a laydown area. This was located within the

farmer’s storage area.

No external audit was conducted during the construction period due to the short time frame for construction.

Construction was from April 2018 to July 2018. The ECO Closure Audit Report, for Condition 6.3.1.1 was

completed in October 2018.


2.2 Auditor Background

Nicholas Gates has been working in the Environmental Management Sector for 11 years during which auditing

has been one of his core functions. He has undergone various training courses such as Lead Auditing and SHEQ

IMS Auditors through institutions such as DQS and ISTEC Safety. Over the years he has gained extensive

experience across the various sectors from Mining, Construction, Energy, etc. either being part of an auditing

team and as lead auditor on a number of projects. Clients include Municipalities, Private Companies,

individuals, SOE’s, etc. and range between the auditing of Landfills, Renewable Energy Projects, etc. against

Environmental Authorisations, Environmental Management Plans and Water Use Licences.


3 METHODOLOGY

This section provides an overview of the methods employed by NCC in providing observations,

recommendations and conclusions derived from audit procedures conducted.

Section 6 of the Environmental Management Programme provides for various Performance Specifications

relating to Environmental Management, this would have been used by the Contractor to guide them in

assisting with the mitigation against environmental damage.

It was also highlighted that the Performance Specification tables detailed within Section 6 of the EMPr will be

audited by the WRECO and Environmental Auditor.

3.1 Audit Process

The site visit, data reviews and report drafting were conducted by NCC’s environmental compliance audit

team. The site audit included the following procedures:

Site Inspection (held on the 1st July 2020), which included:

i. Access Routes;

ii. Infrastructure Maintenance; and

iii. Rehabilitated areas;

Review of Available Site Specific Reports and Documents

i. Review and identification of any audit findings;

ii. Review of ECO reports;

iii. Review of Method Statements; and

iv. Review of remedial measures implements.

Compilation of Audit Report which includes key findings and recommendations

i. A comprehensive report is compiled after site inspection and review of all data, relevant reports,

and interviews.

The report provides recommendations on non-compliance identified during the compliance audit.


3.2 Observation and Recommendation Determination

All recommendations were made according to the following observations within the period that the Auditor

was on site. Observations were based on, and are limited to, the following information sources:

i. Available documentation and records received prior, subsequent, or during the site visit;

ii. Observations made by the audit team during physical site inspections; and

iii. Information received from both direct and cross-referenced interviews conducted with responsible

staff.

3.3 Findings

Key observations as conveyed in Section 6 of this report highlight areas of non–compliance as well as aspects

that require prioritised attention. Each point under this section identifies the observation which it is pertinent

to.

The purpose of these summarised commentaries is to allow SBM to identify common management challenges

that are affecting compliance with the conditions of the documentation audited.

Where findings and recommendations pertaining to the site are deemed significant through compliance status

or performance, they are documented as specific issues in the report. All site specific observations and

recommendations are correspondingly recorded in the audit table (see Annexures A).

As per Section 34(4) of the EIA Regulations, where the findings of the environmental audit report such as:

(a) insufficient mitigation of environmental impacts associated with the undertaking of the activity; or

(b) insufficient levels of compliance with the environmental authorisation or EMPr and, where applicable

the closure plan;

the holder must, when submitting the environmental audit report to the competent authority include

recommendations for consideration to amend the EMPr or closure plan in order to rectify the shortcomings

identified in the environmental audit report.

Any recommendations to amend must be subjected to a public participation process prior to submitting to the

competent authority.


3.4 Audit Tables and Compliance Ratings

The audit table in Annexure A captures all observations and recommendations made in relation to all

conditions stipulated in both Directive and EMPr. They provide the reader with more detailed information in

terms of what the stipulated requirements are in relation to the organisation’s assessed current compliance

status, according to the observations recorded by the auditor during the site visit.

Ratings are calculated based on a scoring system whereby each auditable condition is provided with a score

as highlighted in the table below. The rating system adopted is that which is utilized by the Western Cape

Department of Environmental Affairs and Development Planning (DEADP) whereby each auditable condition

is provided with a score in order to ensure consistency with future auditing and monitoring.

Description Status

Indicator Compliance

Rating Scoring Action

Compliant C 2 85%-100% Minor Improvements Required

Partially Compliant

PC 1 65%-84% Improvement Required

Non-Compliant NC 0 0-64% Major Improvements Required

Not Applicable / Audited

NA - - No Improvements Required or not

relevant at time of audit

Table 1: Compliance Scoring

Each condition has been ascribed a priority indicator of Non-compliant (Red), Compliant (Green) Partially

Compliant (Yellow), and Not Auditable/Audited (Grey) to assist the reader in determining areas that require

attention to ensure compliance is achieved.

Areas that have been shaded indicate that they are sub-condition requirements, they are necessary in order

for the condition to be compliant, non-compliant or not audited/applicable. They have been broken down to

indicate which areas of the condition need to be rectified.

An overall rating is calculated to provide the reader with the overview of the facilities compliance to the

relevant documentation however each condition should be viewed and dealt with on their own merits as the

rating does not provide for, or calculate the severity or impact which might be presented.

For example a site may have an overall rating of 97% which is perceived as good however the 3% worth of

non-compliant conditions may pose a significant impact


4 ASSUMPTIONS AND LIMITATIONS

The compliance audit and report are based upon the assumptions that:

i. Documentation provided to the auditor by SBM was factual and true.

ii. Evidence provided through interviews was factual and true.

iii. The audit is based purely on the conditions as stipulated in the Directive and EMPr issued to SBM’s.

iv. No independent physical or chemical testing, or verification of any description was conducted by the

auditor or NCC as part of the compliance review.

v. Reports were randomly sampled in order to accommodate time constraints

vi. Where visual observations of equipment were not possible either due to the location or complexity to

access the auditor has used other means to determine compliance, either through written evidence

from service providers which utilize the instruments or through interviews with SBM employees whom

work with the equipment.

vii. Specialist studies may run on a different cycle to that of the external audits therefore aligning with

audit findings, however these can be address in following audits.

5 CONSULTATION PROCESS

The consultation process undertaken during the course of carrying out the environmental audit based on

correspondence between the auditor and project representatives.

No consultation with external stakeholders was undertaken.

The final audit report will be distributed to the following Departments as per the requirement of the Directive.

Western Cape Department of Environmental Affairs and Development Planning

Department of Water and Sanitation

Heritage Western Cape

Department of Environmental Affairs: Oceans and Coasts

A meeting was held on the 29th June 2020 with the Department of Environmental Affairs and Development

Planning to discuss any additional audit requirements that the Department may have.

It was confirmed that on a Condition 6.3.1.2 Audit was required for this water intervention project.


6 FINDINGS

Based on the audit conducted, it was established that the ability of the Directive and in particular the EMPr

(and where applicable, the closure plan) was achieved in terms of:

i. Sufficiently provide for the avoidance, management and mitigation of environmental impacts

associated with the undertaking of the activity on an on-going basis;

ii. Sufficiently provide for the avoidance, management and mitigation of environmental impacts

associated with the closure of the facility; and

iii. Ensure compliance with the provisions of environmental authorisation, EMPr, and where applicable,

the closure plan.

6.1 Section 30A Directive

As per the requirement on the Directive a Water Supply Emergency Intervention Plan was required in terms

of Condition 6.2.1, this was provided to the Auditor and use to inform the various water intervention

measures. Further details can be found in Table 1.

Mitigation against Environmental Impacts Associated with Current Intervention

Pre-Construction

No formal botanical or heritage assessments completed prior to construction, however a Hydrogeological

Report as part of a Water Use Licence was compiled

It was indicated that portions of the project was located on active farmland with little indigenous

vegetation as identified by the Municipality Environmental Department, however it was indicated

that a small portion of the project did impact on indigenous vegetation. The layout of the road

(width) and pipe installation areas were kept to a minimum with the use of existing farms roads and

servitude areas as far as possible. To a large extent existing farm roads were utilised for the pipe

route.

Various documents were drafted and tasks by the Contractor prior. This included SHE Plan, Heritage Recovery

Procedure, and staff induction.

Construction

Topsoil was stockpiled separated from subsoil and designated as a no-area.


An Environmental Control Officer (ECO) was appointed to oversee the construction phase of the project and

monitor adherence to the EMPr.

An ECO conducted site inspection and compiled monthly monitoring reports. No major issues were highlighted

in the sampled reports and it was indicated by the ECO that the site was generally well managed.

The ECO reports highlighted that topsoil was set aside and designated as a no go area to be used for

rehabilitation.

Existing access roads were utilized where possible to minimize unnecessary clearance of vegetation.

Rehabilitation

After completion of construction t was spread on impacted areas to support regrowth of vegetation

Rehabilitation was conducted post-construction whereby topsoil was spread on impacted areas to support

regrowth of vegetation. The ECO conducted a site visit and compiled a final close out report whereby no major

issues were identified and regrowth was evident.

6.2 EMPr

Section 6 of the Generic EMPr, Performance Specifications: Environmental Management, was the section

audited against. This is specified in the EMPr where it indicates:

‘Section 6 of the Environmental Management Programme provides for various Performance

Specifications relating to Environmental Management, this would have been used by the

Contractor to guide them in assisting with the mitigation against environmental damage.’

Further details can be found in Table 2 & Table 3.

All applicable conditions were audited and the final percentage rating was measured against these conditions,

which excluded not applicable conditions.

The tables below highlight any the short comings of any conditions which were not deemed fully compliant.

Only conditions deemed non-compliant or partially complaint are displayed, the full audit table is found as

Annexure A.


Compliance with Section 7 of the EMPr

The project employed a number of best practice options highlighted in Section 7 of the EMPr in order to satisfy

the auditable conditions and outcomes as set out in Section 6.

This project addressed compliance in addressing this section through implementing the following various

measures:

(i) Application for Water Use Licence

(ii) Induction of Contractor;

(iii) Identification and demarcation of No-Go areas;

(iv) Environmental budget for Construction Monitoring and Rehabilitation was set aside;

(v) Appointment of an External Environmental Control Officer;

(vi) Laydown Areas located in previously disturbed area;

(vii) Clearing of vegetation only in development footprint areas (Operational Access routes and boreholes

points);

(viii) Topsoil stored and maintained;

(ix) Waste management on site;

(x) Unobtrusive lights installed;

(xi) Hazardous Substance management;

(xii) No indication of unapproved fires;

(xiii) All boreholes points fences;

(xiv) Construction was undertaken during normal working hours;

(xv) Batching undertaken in dedicated area; and

(xvi) Rehabilitation with placement of topsoil on disturbed areas.

All the above was referenced in the ECO reports (Monthly or Close Out)

The Generic EMPr provided adequate measures for the avoidance, management, and mitigation of

environmental impacts associated with this intervention project, however it must be noted that not all

conditions were applicable to this project due to type of intervention (boreholes), location (inland) and relative

low impact of the project coupled with the generic nature of the EMPr.

7 CONTRIBUTION TO CURRENT WATER SUPPLY

It was indicated in the SBM Water Intervention Plan that the West Coast District Municipality (WCDM) already

exceeded their current allocation from the Berg River for the last number of years (Pre-2018). The WCDM

applied for an increase in the license volume to 30 Million kl/annum in 2011, but awarding of this license was

still pending at the time of writing of the report. A water balance indicated that a shortfall would have been

experienced shortly after the report was published. By 2040 the shortfall will increase to 7.616 million kl/a

under low growth scenario to 11.229 million kl/a under high growth scenario if no intervention is put in place.

Water supply as per approved WULA’s prior/during implementation of groundwater projects.

To recap the supply from Western Cape Water Supply System (WCWSS) with its abstraction point being

Misverstand dam was 20 427 000 mᵌ/a prior to the wellfield intervention. SBM had to aim to reduce demand

to 20.35 ML/day during level 6 water restrictions which was deemed impossible without major economic

damage, due to business and industry being the SBM’s biggest consumers. Before the drought SBM was

utilising 37ML/day which was already above the previous allocation.

increased the quantity available to the Municipality during times of need.


8 SUMMARY

In terms of the results and findings of the audit on the SBM Water Intervention measure, Langebaan Phase 2,

it was found that the site is mostly compliant with conditions issued to the project, this can be seen in the

score of 77% compliance across both sets of documentation.

Any findings should however be placed in context of the full audit and each condition and its rating should be

looked at individually and dealt with accordingly.

Majority of the conditions of the EMPr were deemed not applicable as they were addressed in the Close out

Audit conducted by the ECO and deemed acceptable by the Department.

All non-compliant and partially-compliant findings observed were applicable during the pre-construction

phases, this was as a result of general misunderstanding of the Section 30A Directive by SBM and DEADP.

Rehabilitation of the disturbed areas seems to be positive with regrowth in majority of the areas.

Every effort has been made to ensure the site is run effectively and efficiently with minimal impact to the

environment and surrounds.

The project has positively contributed to the water supply as highlighted in Section 7.

Rehabilitation activities have contributed to the mitigation of environmental impacts along with measures

implemented during the Construction phase as monitored by the ECO.

1 INTRODUCTION

1.1 Background

Saldanha Bay Municipality (SBM) appointed the Institute for Water Studies at the University of the

Western Cape to provide specialist hydrogeological input related to the yield of the Langebaan Road

and Elandsfontein Aquifer systems as part of potential emergency water supply, but also as longer term

water supply to Saldanha Bay Municipality.

As part of the emergency water supply measures, the expansion of the Langebaan Road wellfield must

be evaluated to alleviate the water shortage of the SBM. The upgrading of the existing and expansion

of the Langebaan Road wellfield is identified as wellfield 1A (existing boreholes) and 1B (new boreholes)

respectively, with other potential wellfields further away named wellfields 2 and 3. The additional water

available from the Langebaan Road 1B wellfield will be supplied into the WCDM pipeline.

Various hydrogeological studies have been conducted in the past in the Langebaan and Elandsfontein

areas. These include investigations by the Department of Water and Sanitation (DWS), CSIR, local

municipalities and private consultants. These, together with existing geological maps and water

monitoring datasets from DWS were consulted to inform the baseline information for this study.

1.2 SCOPE OF WORK

The following scope of work has been agreed on by the client (SBM) and the Institute for Water Studies:

Compile a geohydrological report for the Langebaan Road wellfield to support the Water Use

License Application by the Saldanha Bay Municipality for groundwater supply of 15 120m3/day

(5.53 x 106 m3/year).

2 BASELINE INFORMATION

2.1 PHYSICAL ENVIRONMENT

2.1.1 Locality

The Langebaan Road Aquifer (LRA) is located between the lower sections of the Berg River and

Saldanha Bay. The Langebaan Road Aquifer falls within the Berg Water Management Area, specifically

in quaternary catchment G10M (Figure 2.1).

The topography of the Berg WMA varies considerably, with consequential impact on the climate of the

region. Rainfall is highest on the mountain ranges where the mean annual precipitation is as high as

3000 mm per annum, whilst the coastal sections receives as little as 300 mm per annum.

The aquifer system is bordered by the Berg River to the north, the Salt River to the east and the

Elandsfontein Aquifer System to the south.

of 33

Figure 2.1: Location of Langebaan Road Aquifer Wellfield.

of 33

2.1.2 Rainfall

Langebaan is situated in a semi-arid Mediterranean climate, with winter rainfall falling between the

months of May and August (Figure 2.2). The study area generally has higher evaporation than mean

annual rainfall and most of the region has an annual rainfall of less than 280mm (DWAF, 2008) (Figure

2.2).

Figure 2.2: Monthly rainfall at Langebaan Road 185-IR.

Figure 2.3: Annual rainfall at Langebaan Road 185-IR.

of 33

2.1.3 Topography

The Langebaan Road Aquifer area has an elevation of approximately 60 mamsl, with a relatively flat

surface The landscape in the Langebaan Road area is not greatly varied. It is characterised by sand

covered plains, fixed dunes, surface limestone ridged and some unvegetated dunes. The Vredenburg

headland, the Darling hills and some isolated koppies are all made up of granite (eg. Vlaeberg and

Konstabelkop) or related instrusives, and reach heights of up to 450m. Otherwise the regional

topography is generally flat to slightly undulating and does not reach elevations beyond 120m

(Timmerman, 1985).

2.2 GEOLOGY

2.2.1 Regional geology

The Langebaan area is dominated by unconsolidated to semi-consolidated sediments that overlay the

basement rock of the Malmesbury Group unconformably (Figure 2.4). The Malmesbury Group consists

of shale outcropping to the west of the wellfield area and along the N7 road from Cape Town to

Piketberg. Deeply weathered shales of the Malmesbury Group and granite plutons of the Cape Granite

form part of the basement rocks.

The Berg River flows approximately parallel to and east of the regional contact between Malmesbury

Group and the Cape Granite suit. The Sandveld Group consists of Springfontyn, Velddrif, Langebaan

and Witzand Formations and extends from False Bay to Saldanha.

2.2.2 Local geology

The coarse Elandsfontyn Formation sand and gravel (do not confuse with the Elandsfontein aquifer

unit) were deposited in a number of paleo-channels, which can be correlated with old courses of the

Kulders-, Berg- and Groen Rivers. These deposits were subsequently covered by clays and peat. The

thickness of the Cenozoic sediments varies between 0 and 120m, with the greatest thicknesses

occurring between Langebaan Lagoon and Hopefield (Timmerman, 1985).

The stratigraphic column of the local geology according to Roberts (2006) is shown in Figure 2.5. The

cenozoic stratigraphy is shown in Table 2.1. Within the Langebaan road wellfield region three formations

are present, namely (in order of oldest to youngest):

the Elandsfontyn Formation, (not be confused with the Elandsfontyn Aquifer or the

Elandsfontein Farm)

the Varswater Formation and

the overlying Langebaan Formation.

2.3 HYDROGEOLOGICAL INFORMATION

2.3.1 Regional Groundwater Occurrence

The Berg WMA does host extensive aquifers. The Klipheuwel and Malmesbury Groups are typically not

known for their high groundwater potential. However, in places – particularly where fracture/fault

systems are well developed – the groundwater potential is very high. In favourable geological settings

borehole yields from these groups can be about 5 ℓ/s and higher whilst the average borehole yield is

lower. The Cape Granites are typically low yielding (~ 1 ℓ/s) and these yields are only obtainable in

highly weathered and faulted zones. Otherwise the granite is very solid and a non-aquifer.

The significant features from the hydrostratigraphy and the palaeotopography that dictate the

groundwater flow regime in the area are (DWAF, 2008):

of 33

The lower (semi-) confined aquifer unit occurs in the palaeo-channels and is unlikely to be

connected between the LRAS and the EAS, as a basement elevation of at least 0 mamsl

separates the two palae-channels.

The upper aquifer unit (UAU) is continuous across the area.

The clay unit confining the LAU is absent along the SW coastline and in the vicinity of the Berg

River.

2.3.2 Local Aquifers

The Langebaan Road Wellfield falls within the Berg River hydrogeological unit of the Sandveld Group

Aquifer. The geological depositional environments and controls determine the most significant

groundwater occurrences. Two significant aquifers exist within the area: the Langebaan Road Aquifer

System (LRAS), which is situated in the northern palaeo-channel and the Elandsfontein Aquifer System

(EAS), which is situated in the southern palaeo-channel.

The LRAS is formed by the thick sand and gravel layers of the Elandsfontyn Formation. The confining

layer is formed by the Elandsfontyn clay and peat. A shallow, unconfined aquifer of lesser extent exists

in the top Bredasdorp calcerous layers.

The clay layer that separates the Elandsfontyn Formation and the Varswater Formation creates (semi)

confined conditions in the basal gravels (GEOSS, 2010). The confined Lower Aquifer Unit (LAU) is the

most significant aquifer in the Langebaan Road area and is generally restricted to paleochannels, which

defines the LRAS and the EAS.

For the Langebaan Road area the geology and hydrogeology are summarized in Table 2.2 (Weaver,

1998a):

3 EXISTING WELLFIELD: HISTORY

Extensive drilling and exploration work was done by DWAF from the mid 1980’s for a period of 10 years.

Documented groundwater assessment studies in the Saldanha Bay/Langebaan Road Area already

started in 1974. The potential of the groundwater resources in the primary aquifers was not only

investigated, but also confirmed as very favourable. The following is a list of the main groundwater

exploration studies:

Timmerman, L.R.A. 1985. Possibilities for the development of groundwater from the cenozoic

sediments in the Lower Berg River region. Geotechnical Report GH3374, Directorate:

The existing wellfield at the Langebaan Road Aquifer was officially established for the DWS in 1998.

Recommendations by Weaver for the sustainable abstraction (based on pumping test interpretation)

from the wellfield are summarised in Table 3.1.

Following these recommendations, the Langebaan Road wellfield became operational in 1999,

providing an additional 4 000m3/day to the water supply for Saldanha Local Municipality. In 2008

and 2009 artificial recharge was tested at the wellfield, showing that it could be a viable option for

the long term sustainable management of the groundwater resources. Monthly abstraction figures

of 33

(Figure 3.1) were available for the period September 2005 to September 2015, with the periods of

no pumping can clearly be extinguished.

Figure 3.1: Total Monthly abstraction for LRA wellfield.

4 GROUNDWATER LEVELS

The water level trends (as recorded in DWS monitoring programme) for the Langebaan Road Wellfield

area are illustrated in Figure 4.1. Water levels response to the local abstraction show drops in water

level of about 10m for the different monitoring holes. Good recovery of the water levels are observed

during pump shutdowns and maintenance events. Currently only monthly hand readings is taking place

at the wellfield due to failure of the data loggers.

Additional available drawdown of 20m to a depth of 35m below casing is available at the wellfield before

the confining conditions of the wellfield are influenced.

5 GROUNDWATER RECHARGE

The effective groundwater recharge from rainfall is the portion of rainfall that reaches the groundwater.

The remainder of the rainfall comprises surface water runoff, evapotranspiration and soil moisture. The

effective rainfall-recharge is dependent on the catchment geology, soils, surface run-off and stream

morphology but most importantly for the study area, the effective storage.

As the size of the sub-catchment falls within the G10M quaternary drainage area, the rainfall is seen

to be equal across the site, i.e. 14mm/annum.

Two general approaches were utilized to estimate the groundwater recharge in the study area:

• Literature values; and

• Calculation using chloride as an environmental tracer – so called chloride mass-balance

method (CMB method).

5.1 Literature Values

Based on the literature review, a conservative average recharge of 8.2% was taken for the study

area. In Table 5.1 is a summary of the recharge values obtained from the literature review.

area.

5.2 Chloride Mass-Balance (CMB) Method

Environmental tracers such as chloride (Cl) are produced naturally in the Earth’s atmosphere and are

used to estimate recharge rates. Input of chloride occurs in the soil both in rainfall and as dry fallout.

Most plant species do not take up significant quantities of the chloride from soil water, thus chloride is

concentrated by evapotranspiration in the root zone. In the simplest case of piston flow of water in the

unsaturated zone, the chloride concentration in soil water should increase through root zone to a

constant value.

Under steady state conditions flux of chloride at the surface is equal to the flux of chloride beneath the

root zone, thus:

P*Cp = R*Cs,

where Cp = chloride concentration in precipitation Cs = chloride concentration in groundwater

R = mean annual recharge (mm) P = mean annual precipitation (mm).

of 33

The mean annual precipitation (MAP) is 300mm for the study area, with chloride concentration in the

rain water ranging from 5 to 10 mg/l and chloride concentration in groundwater ranging between 114

and 209mg/l (DWS monitoring). The output rainfall recharge obtained by substituting these values then

ranges between 13 and 14mm per year.

6 GROUNDWATER QUALITY

Based on field data from various studies in the area over the last 20 years, the water quality of the

aquifer is good (less than 100 mS/m). Generally the water quality of the LAU is better than that of the

UAU but from the field EC measurements it suggests that all the groundwater is of a good quality.

The upper and lower aquifer units of the study area have different water qualities. Groundwater quality

is good in the Lower Aquifer Unit (LAU) with ECs <100 mS/m. Groundwater from the upper aquifer is

rich in Na/Cl, and has a higher EC than the lower aquifer.

A summary of the groundwater quality analyses for the DWS monitoring stations at the Langebaan

Road Aquifer is provided in Table 6.1. For each of the stations, the first documented analysis as well as

the most current analysis are listed in order to detect prominent changes, in the overall groundwater

quality at the wellfield.

Time series EC is plotted to evaluate if any significant changes in total salts in the system are evident

(Figure 6.1). Most of the boreholes do not show any significant change in Electrical Conductivity, except

for borehole G46032 showing an increase in salts between 2006 and 2010. The increase in salinity does

not seem to be related to the pumping at the wellfield, but rather the impact of nearby waste water

treatment works.

Figure 6.1: Electrical conductivity (EC) trends at the LRA wellfield.

Borehole G46032 is situated in the upper aquifer near the Langebaan Road Airfield wastewater treatment,

and this increase of salt concentrations could be as a result of the impact of the sewage water irrigation at

the treatment works. The nitrate concentrations typically associated with sewage water follows a similar

trend to the Electrical Conductivity (Figure 6.2).

Figure 6.2: Electrical Conductivity and Nitrate for G46032 in Langebaan Road upper

aquifer.

of 33

Consistent monitoring at regular intervals at all of these boreholes will ensure that changing trends are

picked up in advance and adaptive measures be put in place if necessary. Land use activities like irrigation

and wastewater treatment can influence the groundwater quality of the upper aquifer, but should not

influence the lower aquifer. Early warning water quality monitoring in the protection zone of the wellfield

should be conducted to ensure the water quality for drinking water purposes. Studies identifying recharge

areas for the lower aquifer will be important to improve management and prevent contamination reaching

the water supply boreholes.

A Piper diagram (Figure 6.3) was constructed with the same DWS water quality monitoring data. The

Langebaan Road Wellfield has a sodium chloride type of water and this is expected because this area

receives coastal rainfall. The high bicarbonate and calcium content in the water is most likely from the

calcarenite and the lime rich shells, which are present within the geology of this area. Calcarenite is a

type of limestone that is composed of transported sand-sized, carbonate grains, which have accumulated

as coastal sand dunes (Khalifa, Mohamed et al 2009). When this calcium carbonate rich geology comes

in contact with water it dissociates and bicarbonate is formed.

In general the water chemistry in the past is similar to that of the present but this is not evident in

boreholes G46059 and G46105. In 2001, borehole G46059 was more saline (with approximately 90%

sodium and 70% chloride in 2001) than in 2016. In 2008 borehole G46105 was more saline (with

approximately 90% sodium and 80% chloride in 2008) than in 2002.

Spatial distribution of the EC values from the DWS water quality database are plotted in Figure 6.4. The

lower aquifer shows low EC values of between 57 and 78 mS/m. The upper aquifer contains slightly more

salts around the Langebaan Road air force base and ranges between 61 and 614 mS/m. Various samples

from unknown depths are available and ranges from 60 to 1021 mS/m.

7 PROPOSED LANGEBAAN ROAD WELLFIELD EXPANSION

It is realistic to expect that additional groundwater from the Langebaan Road wellfield can

be abstracted, based on the historical sustainable yield assessments and available drawdown

in the aquifer.

Timmerman (1985) estimated a short-term abstraction rate at 53 400 m3/day (19.5 M m3/a)

from the Langebaan Road aquifer based on a 15% recharge using the average rainfall data

that was available in 1985 (1985b). As this value was based on average rainfall measurements

available at the time of the study and a slight over estimation of recharge rates, this available

volume is very likely to be non-sustainable as a result of climate change and an improved

knowledge of the system. This abstraction rate (19.5 M m3/a) is therefore not recommended.

Using the capture principle, Seyler (2016) proposed that between 3.5 to 5.5 M m3/a may be

available for abstraction from the wellfield without significant impact on the aquifer or the

environment, compared to the production abstraction rate of 1.1 M m3/a. This translates to

9 590 - 15 070 m3/day (15Ml/day), see Figure 7.3.

A summary for previous assessments of the potential yield of the Langebaan Road Aquifer, is

provided in Table 7.1:

Weaver, 1998 7.8

Seyler, 2016 3.5 – 5.5

Some limitations to the pump and pipe infrastructure currently in place at the wellfield can

be overcome through the increase of both the number of boreholes and the pipe sizes

supplying the West Coast District municipality pipeline.

Additional abstraction boreholes are recommended to spread the drawdown over a number

of abstraction points to limit localised impacts of the higher abstraction rate, Figure 7.4.

of 33

7.1 Conceptual wellfield design

The current Langebaan Road 1A wellfield production boreholes are spread out and about

300m apart. All of these boreholes must be equipped to address the emergency water supply

needs.

Three (3) additional production boreholes, at 600m apart, must be installed in a northerly

direction (Figure 7.2). Figure 7.1 shows a cross section with the relative placement of the

boreholes from each other. The clay layer separating the upper and lower aquifer is expected

to become thinner, while the bedrock topography is expected to become deeper across the

section.

Figure 7.1: Conceptual cross-section at Langebaan Road Aquifer for existing

and proposed expansion of wellfield.

of 33

Figure 7.2: Position of cross-section line across LRA.

of 33

7.2 Water available from total wellfield

The new expanded and upgraded combined wellfield 1A and 1B will have a maximum

abstraction rate of 175 l/s (15 120 m3/d) based on the limit of the pump and pipe

infrastructure.

Realistically this maximum supply is only needed until the winter rainfall starts and some

surface water becomes available. A reduction in the abstraction rate to 100 l/s (8 640 m3/d)

is expected during winter months.

For the water use license, it is recommended that the total volume of 175 l/s (15 120 m3/d)

is allocated to the Saldanha Bay Municipality on condition that the water level response to

the abstraction do not reach the bottom of the clay layer. The development of Langebaan

Road wellfields 2 and 3, as well as the Hopefield B wellfield should be considered as part of

the long term water supply and the spatial distribution of abstraction points to limit the local

drawdown.

The immediate need for the current drought situation is an allocation of 3.7 M m3 for 2018

and a maximum of 5.53 M m3 for the following years (Figure 7.4). It is realistic to expect that

less water will be abstracted when surface water becomes more available.

8 GROUNDWATER RESOURCE STATUS– LANGEBAAN ROAD AQUIFER UNIT

The geological setting is favourable for the occurrence of groundwater. The volume

requested for abstraction is 5.53 x 106 m3/year.

For approximately the last two (2) years, no abstraction has taken place form the existing

wellfield.

Based on the testing completed during previous investigations as well as the monitoring of

the wellfield during the period it was operational, the license application volume is

considered to be within the sustainable supply volume of the aquifer.

The boreholes have been tested originally (Weaver, 1998) to determine the sustainable yield

that can be abstracted from the aquifer system. The yield test indicated that a sustainable

abstraction rate of 7.8 x 106 m3/a could be achieved from the aquifer system.

The groundwater is of good quality, with EC-values below 100 mS/m from production in 1999

until 2016 (latest analysis results).

of 33

8.1 GROUNDWATER REQUIREMENT

The SBM requires the groundwater supply of 5.53 Mm3/year from the Langebaan Road 1A and

B wellfields, which will be distributed by the municipality for domestic and industrial users.

8.2 GROUNDWATER SUPPLY

A yield of 5.53 x 106 m3/a can be obtained from the planned expansion of the wellfield. Seven

(7) boreholes will be utilized to abstract the required volume, and the scheduling for the short

term is discussed in Section 6. This will need to be closely monitored to ensure sustainable

supply.

Hence, the sustainable groundwater supply of 5.53 x 106 m3/a is requested in this license

application.

Once the proposed infrastructure and hydraulic testing for Langebaan Road Wellfield 1B has

been established, a hydrogeological report will be submitted to the DWS, containing borehole

and drilling data, pumping test results, hydrochemical analyses and yield recommendations.

8.3 Wellfield management

The cumulative abstraction from the wellfield needs to be carefully managed as the boreholes

are abstracting from the same resource. A detailed monitoring plan is discussed in the next

section of this report.

of 33

8.4 Groundwater monitoring and management plan

In terms of DWAF’s overarching water quality management objectives which are (1) protection

of human health and (2) the protection of the environment, the significance of this aquifer

classification is that if any potential risk exists, measures must be triggered to limit the risk to

the environment and other users.

A detailed groundwater monitoring plan is presented in Section 9 of this report.

9 GROUNDWATER MONITORING

9.1 Water Levels

The current Langebaan Road Wellfield 1A monitoring boreholes provide good information

regarding the wellfield response to abstraction, but limited data regarding the responses

towards the Elandsfontein Aquifer to the east and the main Langebaan Road Aquifer towards

the north. The existing monitoring will provide early warning to wellfield drawdown limitations,

but not regarding sustainable resource use.

The monitoring network therefore will need to be expanded to include additional data. Based

on the interpretation of the aquifer structure and basement topography it is recommended that

at least three (3) additional monitoring boreholes be drilled to provide data for management

of the LRA, update of the numerical model and provide data regarding the interaction between

the different aquifer horizons.

Three sites have been identified, expanding the current monitoring network with two (2) lower

aquifer and one (1) upper aquifer monitoring borehole. These are summarised in Table 9.1 and

their positions are indicated on Figure 9.1.

Table 9.1: Additional recommended monitoring boreholes.

Coordinates (WGS84) Borehole Name

Aquifer Unit Depth Lat Long

-32.973864° 18.205147° LRA1B-1M Lower Aquifer 80

-32.970600° 18.184800° LRA1B-2M Lower Aquifer 80

-32.978600° 18.199100° LRA1B-3M Upper Aquifer 20

Continuous monitoring using electronic data loggers should be implemented and maintained

on the existing LRA 1A as well as the new LRA 1B monitoring boreholes. Daily logging intervals

is recommended.

of 33

9.1 Water quality

The additional flow rates can result in unwanted water quality changes due to inflow from

adjacent low yielding formations with different water quality and should be monitored. Some

early waring protection zone monitoring should also be implemented to protect the drinking

water resources from surface activities in the catchment.

Quarterly water quality monitoring on all the production boreholes should be conducted. The

analyses should include Anions, Cations and a trace metal scan. On a bi-annual interval

additional water isotopes 2H and 18O and selected contaminants of emerging concern (Atrazine,

Glyphosate, AMPA) should be included. These additional analyses will form a good baseline

with a view on potential future artificial recharge with surface water and treated wastewater.

9.2 Abstraction volumes

Each of the production wells should be equipped with a flow meter. The total volume abstracted

should be recorded on a monthly interval.

9.3 Monitoring report

A monitoring report with the abstraction volumes, water level response and water quality

changes should be submitted to the Department every year.

The monitoring data should be stored in an acceptable format in a database with sufficient

backup and provided to the Department on an annual basis.

Hard copies of field sheets and laboratory reports must be kept safe so that they can be made

available to the Department or other stakeholders on request.

9.4 Monitoring committee

A monitoring committee should be put in place that includes the surrounding stakeholders,

including the stakeholders from the Elandsfontein aquifer system. The monitoring committee

should meet at least every six (6) months to discuss monitoring results and management of

the wellfield.

The monitoring requirements stipulated in the monitoring protocol must be agreed upon by the

relevant stakeholders that form part of the monitoring committee.

9.5 Numerical model Updates

A regional flow model and a wellfield model be developed and kept up to date with the most

recent monitoring data for wellfield and aquifer management purposes.

Amongst others the flow model should be used to determine the capture zones for the wellfiled

following best practice local and international guidelines to protect the drinking water to the

wellfield.

of 33

It is recommended that the numerical flow model be updated against the new monitoring data

on an annual basis. This will provide improved certainty to DWS regarding the sustainable use

of the Langebaan Road aquifer system.

10 SUMMARY AND RECOMMENDATIONS

10.1 Summary

The geological setting in the Lower Aquifer of the Langebaan Road Aquifer is favourable for the

occurrence of groundwater. The volume requested for abstraction by the Saldanha Bay Municipality

is 15 120 m3/day or 5.53 x 106 m3/year.

Based on the numerical modelling and aquifer testing completed during previous investigations as

well as the monitoring of the wellfield during the period it was operational, the license application

volume 5.53 x 106 m3/year is considered to be within the sustainable supply volume of the aquifer.

A yield of 5.53 x 106 m3/a can be obtained from the planned expansion of the wellfield. Seven (7)

boreholes will be utilized to abstract the required volume. This will need to be closely monitored to

ensure sustainable supply.

The groundwater in the lower aquifer is of good quality, with EC-values between 57 and 78 mS/m.

Monitoring of both water level drawdown response and water quality changes are required to improve

predictions of the system behaviour under these increased abstraction rates. Water levels should not

be allowed to drop below the clay layer and water quality should be monitored to ensure that drinking

water quality is maintained.

Additional monitoring boreholes will be required to provide data for local management of the aquifer,

update of future numerical models and interaction between the different aquifer horizons. Studies

investigating the recharge areas for the lower aquifer will be important to improve management of

the sustainable yield and to protect the aquifer from contamination.

The development of Langebaan Road wellfields 2 and 3, as well as the Hopefield B wellfield should

be considered as part of the long term water supply and the spatial distribution of abstraction points

to limit the local drawdown.

It is recommended that the numerical model be updated every 12 months. This update can then

calibrate against the stresses induced by the expanded wellfield and provide improved certainty for

any future abstraction requirements.

Consulting Engineers on a fortnightly basis in order to ensure continuous improvement with

regards to environmental related matters. The aim is furthermore, to increase the contractor’s

compliance rating in terms of the approved project EMP. The aim of the informal reports are

therefore to assist in identifying environmental related issues and/or concerns in order to take

corrective action on a weekly basis, as environmental degradation is more likely to occur

should Contractors only receive ECO reports on a monthly basis.

This FORMAL report incorporates the findings of the informal reports and furthermore may

include corrective measures/actions which were taken by the contractor and/or Consulting

Engineers. The formal report, which is submitted to the competent authority as well as other

relevant role players and stake holders are prepared on a monthly basis.

GENERAL FINDINGS

No-Go areas

All areas outside the approved development area are strict No-Go areas. Rivers (including

their riparian zones) and wetlands should be treated as No-Go areas outside the approved

footprint and appropriately demarcated as such. No construction machinery or work force is

allowed in the No-Go areas. Please ensure that no machinery or workforce go beyond the

construction footprint. Please note that topsoil is also seen as No-Go area.

Topsoil

Topsoil must be deemed to be the top layer of soil containing organic material, nutrients and

plant/grass seed. For this reason it is an extremely valuable resource for the rehabilitation of

vegetation of disturbed areas. All topsoil should be windrowed (preferred option) to the one

side of the trench and the subsoil to the other side. The backfilling of the subsoil must be done

before the spreading of the topsoil over the disturbed area. Please ensure that topsoil in not

contaminated with construction material. If topsoil is to be stockpiled the stockpiles may not

be higher than 2m. Topsoil management is of the utmost importance when construction takes

place within the natural vegetation area.

Toilets

Please ensure that the construction site is equipped with a sufficient amount of chemical toilets

for the amount of workers on site. At least 1 chemical toilet per 15 workers is required no more

than 150m away from the construction activities. All chemical toilets have to be properly

secured to prevent the toilet from falling over in windy conditions. Penalties will be issued if

workforce is found not using the provided toilets or for a lack of sufficient amount of toilets.

The toilets were secured to the ground and the amount was sufficient.

Fuel storage

If fuel is to be stored on site in the form of a bowser, the bowser must be maintained by the

fuel supplier and/or Contractor and is to be kept clean and leak free. The bowser is to be kept

on site with a drip tray at all times and please ensure that drip trays are used during refuelling

of machinery and generators. A drip tray was found underneath the bowser.

Dust/silt

Please appoint someone to clean the road at the entrance to the site should the need arise.

At the moment dust suppression on site is not a major concern as the construction works takes

place on a farm. As soon as the works takes place close to R45 dust suppression should be

monitored. Please ensure that alternative measures to using potable water are considered for

dust suppression.

Cement

Small and large scale cement batching must be done on mortarboards and/or on plastic

sheeting that serves an impermeable surface to prevent cement water from infiltrating the soil.

Please ensure that mortarboards and plastic sheeting are properly positioned to prevent any

surface runoff. No cement batching may be done directly on the soil as cement water is highly

alkaline and may change the pH of the soil causing decreased soil fertility. Mostly premix

concrete will be used on site. The entire site must be monitored for any concrete spillages, if

any spillages are found, they must be removed from site and be disposed of at a registered

Waste Landfill site or be used as fill material for the road. No concrete spillages/remains may

Page | 3

be spoiled on site. No concrete truck chutes would be permitted to be washed on site. Batching

was done on mortarboards.

Litter

All construction litter, except empty cement bags, must be placed within a litter structure or

bin. Empty cement bags must be placed within a weatherproof bin. The litter structures and

bins must be properly enclosed to prevent any litter from blowing around on site. Please

monitor the soil around the enclosure for any excessive cement water potentially flowing into

the surrounding natural vegetation. Please ensure that a sufficient amount of bins or litterbags

is placed where the workforce is working. Please conduct regular chicken parades to remove

litter from site. Please ensure that empty cement bags are placed within an enclosed bin to

prevent cement leaching during rainy events.

Rubble

Please ensure that the construction rubble do not mix with the topsoil/subsoil as the

construction rubble must be removed from site. Concrete rubble may be disposed at a General

waste facility. Please ensure that rubble is removed on a regular basis.

Erosion and sedimentation control

Silt traps have to be utilized during all dewatering activities to prevent siltation of watercourses

or storm water systems. Silt traps either have to partially filter the suspended solids or allow

settlement in a manageable location. Please ensure that silt traps are being used during

dewatering.

MAJOR AREAS OF CONCERN

No major areas of concern were found on site.

CONCLUSION

The construction activities at the site during the time of audit were well managed. The general

impression of the site was orderly and tidy.

PRINCIPLES OF THE EMP WHICH WERE AUDITED

The EMP was compiled using the following concepts and implementation requirements so that

the higher principles of sustainable development are realised: The EMP can therefore be seen

as a flexible and responsive document.

Continuous improvement. The project proponent (or implementing organisation) must be

committed to review and to continually improve environmental management, with the

objective of improving overall environmental performance.

Broad level of commitment. A broad level of commitment will be required from all levels of

management as well as the workforce in order for the development and implementation of

this EMP to be successful and effective.

Flexible and responsive. The implementation of the EMP must be responsive to new and

changing circumstances, i.e. rapid short-term responses to problems or incidents. The EMP

is a dynamic “living” document and thus regular planned review and revision of the EMP

must be carried out.

Integration across operations. This EMP is integrated across existing line functions and

operational units such as health, safety, and environmental departments in a

company/project. This is done to change the redundant mindset of seeing environmental

management as a single domain unit.

Legislation. It is understood that any development project during its construction phase is

a dynamic activity within a dynamic environment. The Developer, Engineer, Contractor,

and sub-contractor must therefore be aware that certain activities conducted during

construction may require further licensing or environmental approval, e.g. river or stream

diversions, bulk fuel storage, waste disposal, etc. The Contractor must consult the RE,

EO and ECO on a regular basis in this regard.

Dear Sir

COMMENTS ON THE ENVIRONMENTAL AUDIT REPORT SUBMITTED AS THE SECOND AUDIT REPORT FOR

THE LANGEBAAN AQUIFER GROUNDWATER INFRASTRUCTURE PROJECT WITH RESPECT TO THE SECTION

30A DIRECTIVE FOR THE PROVISION OF ADEQUATE WATER SUPPLY TO THE AREAS WITHIN THE

JURISDICTION OF THE SALDANHA BAY MUNICIPALITY.

1. The updated Water Supply Emergency Intervention Plan dated July 2018 and received by this

Directorate on 10 July 2018 (Ref. No. 16/6/F4/17/3140/17), this Directorate’s acknowledgement thereof

dated 17 July 208, the addendum to the updated Water Supply Emergency Intervention Plan dated 19

February 2020 and received by this Department on 05 March 2020, this Directorate’s acceptance

thereof dated 02 April 2020, the Environmental Audit Report dated and received by this Department via

electronic mail correspondence on 07 August 2020 and this Directorate’s acknowledgement thereof

dated 19 August 2020, refer.

2. Comments on the Audit Report (dated 07 August 2020) are as follows:

2.1. According to the Audit Report (dated 07 August 2020), a 77% compliance rating has been

achieved.

2.2. Reporting of compliance with the requirements of the Section 30A Directive (Ref. No.

16/6/F4/17/3140/17):

2.2.1. Although non-compliance with paragraph 6.3.1.2 of the Section 30A Directive (Ref. No.

16/6/F4/17/3140/17), in terms of the submission of the second audit report within three (3)

months of completion of the emergency measure or intervention, was noted by the auditor,

the submission of the Audit Report dated (07 August 2020) is in fulfillment of this requirement.

http://www.westerncape.gov.za/eadp



REFERENCE NUMBER: 16/6/1/F4/17/Langebaan Phase 1 Page 2 of 3

2.2.2. The Audit Report (dated 07 August 2020) indicates that the Langebaan Phase 1 project has

contributed significantly to the water supply emergency situation and has improved the

water supply security in the area by 3 030 000m³ of water per annum.

2.2.3. The Section 30A Directive (Ref No. 16/6/F4/17/3140/17) requires that the Audit Report detail

how all the environmental impacts associated with each measure or intervention

implemented, have been mitigated. The Audit Report (dated 07 August 2020) does not

indicate the environmental impacts associated with the proposed development and does

not report on how each impact has been mitigated.

2.2.4. Proof of submission of the Audit Report (dated 07 August 2020) to the Department of Water

and Sanitation, Heritage Western Cape and the Department of Environmental Affairs:

Oceans and Coasts has not been provided.

2.3. Reporting of compliance with the Environmental Management Programme (“EMPr”)

2.3.1. Although the Audit Report (dated 07 August 2020) reports on compliance with the

performance specifications tables detailed in Section 6 of the EMPr (dated 14 December

2017), it is unclear as to whether the mitigation measures detailed in Section 7 of the EMPr

(dated 14 December 2017) were implemented during the planning, pre-construction and

construction phases of the proposed development.

2.3.2. Based on the fact that the ability of the EMPr to sufficiently provide for the avoidance,

management and mitigation of environmental impacts associated with the proposed

development was based on the assessment of compliance with Section 6 of the EMPr

(dated 14 December 2017), the outcome of the Audit Report (dated 07 August 2020) is

deemed to be premature. The ability of the EMPr to sufficiently provide for the avoidance,

management and mitigation of environmental impacts associated with the proposed

development must be based on the assessment of compliance with Section 7 of the EMPr

(dated 14 December 2017).

3. The Audit Report (dated 07 August 2020) must therefore be amended to include the following;

3.1. In terms of the reporting of compliance with the Section 30A Directive (Ref No. 16/6/F/17/3140/17),

the amended Audit Report must, inter alia:

3.1.1. Detail how all the environmental impacts associated with each measure or intervention

implemented have been mitigated; and

3.1.2. Include proof of the submission of a copy of the Audit Report to the Department of Water

and Sanitation, Heritage Western Cape and the Department of Environmental Affairs:

Oceans and Coasts.

3.2. In terms of the reporting of compliance with the EMPr, the amended Audit Report must, inter alia:

3.2.1. Report on compliance with Section 7 of the EMPr (dated 14 December 2017);

3.2.2. Report on the ability of the EMPr to sufficiently provide for the avoidance, management and

mitigation of environmental impacts associated with the proposed development must be

based on the assessment of compliance with Section 7 of the EMPr (dated 14 December

2017).

4. The amended Audit Report must be submitted to the Competent Authority for approval by no later than

30 November 2020.

5. You are advised that compliance site audits may be forthcoming and that you may be informed of such

site audits accordingly.

The Department reserves the right to revise or withdraw comments or request further information based on

any information received.
