1. DETAIL AND EXPERIENCE OF THE EAP WHO PREPARED THE EMPR
Sillito Environmental Consulting (SEC) has been appointed as the independent Environmental Assessment Practitioner (EAP) to apply for a Waste Licence for the proposed adaptation of an effluent Biodigester plant at the RCL Foods chicken processing facility, McAlister Road, Worcester. This report was prepared by Colleen McCreadie of SEC, and reviewed by Adrian Sillito. Adrian Sillito is a certified environmental assessment practitioner (CEAPSA), Professional Natural Scientist (Pr.Sci.Nat.) and a member of the International Association for Impact Assessment (IAIA). Adrian has over twenty years’ experience in the field of environmental management and impact assessment. Colleen has an Economics Honours degree from UCT and has ten years’ experience in environmental management and impact assessment. She is also a member of IAIA. Please refer to EAP Curriculum Vitae’s contained in Appendix F.
2. INTRODUCTION 1.1 Project Description Introduction The development proposal is for the adaptation of an existing waste-to-value plant, which is situated at the RCL Foods chicken processing plant on Erf 4396, McAlister Road, Worcester Industria. Currently, the waste-to-value plant generates biogas through a process of anaerobic digestion of the effluent sourced from the chicken processing plant. The biogas is then burnt to generate electricity for use by the RCL plant, and the treated effluent is discharged to municipal sewer. This EMPr is therefore to be read together with the EMPr authorised in terms of Environmental Authorisation reference number 16/3/3/1/B2/32/1010/15, dated 6
th January 2016.

- 5 - It is now proposed to include animal manure from nearby RCL Foods poultry farms and other farms as a feedstock for the waste-to-value plant. This will entail the installation of additional digester tanks and associated infrastructure. The design of the adapted waste-to-value plant will allow for up to 10MW of electricity to be generated, which is expected to power a large majority of the RCL Foods processing facility, including the waste-to-value plant itself. This is an expansion from the approximately 1.5MW currently generated by the effluent digestion plant. Waste heat generated during biogas combustion will also be used to generate steam and hot water for integration back into the processing plant. In addition to this, the manure digestion process generates as a by-product a digestate. The digestate provides a high quality agricultural fertilizer, which will be sold to nearby farms. The development proposal is aimed at valorising waste from RCL activities in the Worcester region, in order to: reduce RCL’s natural resource consumption for power and water purposes; provide a stable source of power and treated water to the RCL plant; and produce a biologically stable, high-quality fertilizer for sale by RCL. Please refer to a detailed process description contained in Appendix J. This includes a description of inputs, outputs, emissions and waste; infrastructure required; potential impacts identified with the process; and recommended mitigation to reduce identified impacts to acceptable levels. A summary of the key elements of the process is included here: Anaerobic digestion process Manure will be blended with dilution water from the downstream digestate dewatering process (see “Digestate” below) and added to digestion tanks. The manure digestion tanks are designed to maximise the conversion of the organic matter in the waste through various exothermic reactions to energy-rich biogas for conversion into useful energy. The digestion process will take some 55 days. The manure digesters will have the capacity to convert up to 100 ton per day of manure feedstock. A digestate will be produced as a product of the waste digestion process. This digestate is suitable for use as an agricultural fertilizer. Biogas combustion process The Biodigester will have the capacity to produce approximately 2000m
3/hour of biogas
1, comprising 50-75%
methane; 25-50% carbon dioxide; 0-10% nitrogen; 0-1% hydrogen; 0-3% hydrogen sulphide; and 0-2% oxygen. Compounds in the biogas can cause corrosion and precipitation leading to premature equipment failure. The biogas will be conditioned in a gas treatment unit that employs a process of cooling and filtering to remove these problematic compounds prior to combustion. The biogas will be combusted in combined heat and power engines (CHP’s), which have the capacity to combust all of the biogas produced by the digesters. The electricity produced – up to 10MW - is expected to be sufficient to power the majority of the RCL plant. The waste heat produced will supplement some of the coal energy supply currently used at the coal fired boilers on the site. The plant is anticipated at this stage to include at least five CHP engines. Digestate The biodigestion process will produce approximately 80 tonnes per day of digestate as a by-product. The digestate is biologically stable, resisting further breakdown under normal storage conditions. The digestate comprises about 30% solids and 70% moisture. The digestate is free of pathogens and is a high quality agricultural fertilizer. The digestate will be sold to agricultural users. Digestate exiting the digester tanks will be dewatered using decanter centrifuges. The digestate will be stored in a weatherproof unit for controlled storage and loading. The liquid fraction from the dewatering process will be treated and returned as dilution water to the manure digestion process. Manure and digestate transport and conveyance
1 The biogas is continuously piped to the CHP engine so that at any one time, only up to 500m
3 of storage capacity for the biogas
is required.
- 6 - The manure and digestate (fertilizer) will be transported to and from site in fully enclosed, moving-floor trucks. These deliveries will take place daily. Manure will be offloaded in a dedicated storage unit. Digestate will be loaded at a dedicated area of the plant. In terms of conveyance of manure and digestate within the plant, this all takes place within a closed system: all pipelines, conveyer belts, screw presses, etc. are enclosed. Water recovery process An additional adaptation to the current waste-to-value plant is the installation of a water recovery plant. A portion of the treated effluent discharged from the effluent digesters (i.e. RCL effluent) will be used to feed the water recovery plant. This plant will treat the treated effluent using a specialised Reverse Osmosis (RO) membrane system designed for high fouling applications. The feed will be separated into a high quality permeate stream and high strength brine stream. The brine, about 200m3/day, will be blended into the remaining final effluent discharged to municipal sewer. The RO plant will consist of the following steps: gravity settling, sand filtration, cartridge filtration and RO. The process will take place in a series of bulk tanks. Recovered water produced will be returned to the factory to reuse at suitable points and applications (filling cooling towers, boilers, cleaning of exterior working areas and crate washing). This represents a reduction in the quantity of effluent currently being discharged to municipal sewer; as well as a reduction in water usage at the chicken processing plant. Infrastructure Infrastructure required will be as follows:
1) Digestion tanks for the anaerobic digestion of the manure to produce biogas 2) An enclosed, purpose-designed structure for the offloading and storage of the manure for up to three days.
The unit will include a receiving bay in which the doors will only be opened during a manure delivery. 3) The manure storage structure will operate under negative pressure, with air extracted to a filtration system for
removing odorous emissions prior to exhausting to atmosphere. 4) The filtration system will be a two-stage chemical scrubber aimed at scrubbing ammonia and hydrogen
sulphide from the air exhausting from the storage unit. 5) Decanter centrifuges for dewatering the digestate. 6) An ammonia stripper (heat exchangers and ammonia scrubber), for stripping ammonia from the liquid fraction
of the digestate. 7) A weatherproof unit for the controlled storage and loading of digestate. 8) A gas train comprising desulphurisation, dehumidification and pressure upgrading stages. 9) At least five Combined Heat and Power (CHP) engines. 10) A series of tanks for water recovery – for gravity settling, filtration, RO and treated water storage prior to return
to the RCL plant. 11) Pipelines for the conveyance of manure; digestate; treated effluent; hot water; processed water; biogas and
steam. 12) Distribution lines for electricity.
There will be no need for additional connections to the municipal water or electricity supply network; or to the municipal sewerage or stormwater systems. The plant will utilise the existing site access off McAlister Street, with the traffic generated by the delivery of manure expected to be up to 5 trucks per day, i.e. a negligible increase in traffic given activities taking place in the surrounding industrial area. It is expected that these same delivery trucks once empty will be loaded with the dried digestate to transport the fertilizer to agricultural users. In terms of standby electricity, the plant will draw power from RCL’s electricity mains only during ramp up and until adequate electricity has been generated by the Biodigester to start the CHP engines. This will entail about 400kW over a period of about two weeks. Also, in the unlikely event of substantial maintenance, where the plant would need to be recommissioned, RCL mains electricity will be used. Waste and effluent disposal and discharge Waste: the manure is conveyed from the storage structure in a closed system to a blending tank, where effluent is added. This floats out the bedding material present in the manure, and settles out the grit (soil), which are unwanted in the Biodigesters. The optimised manure mixture is then conveyed to the Biodigesters. The bedding material is conveyed to the digestate tank via a screw press for dewatering purposes. The grit is discharged to a covered skip, which is emptied periodically and the grit disposed of to landfill.
- 7 - There is no other waste associated with the Biodigester plant. Effluent: A portion of the outflow from the effluent Biodigester (i.e. treated RCL effluent), which is currently all discharged to the municipal sewerage system, will be diverted to the RO plant. The high strength brine stream from the RO process (about 200m
3/day) will be blended into the remaining effluent stream discharged to sewer. The treated
water from the RO plant will be utilised in the boilers, cooling towers, to wash crates, etc. The RO plant therefore represents a nett reduction in effluent outflows to the municipal system. With regards to spent scrubber solution from the emissions scrubbers, this will also be blended into the remaining effluent stream that discharges to sewer. The volumes are very small (<4m
3/day). Any change in the composition of
the effluent being discharged, will be reflected in an amendment of the RCL plant’s effluent discharge permit, if required
2.
2 The applicant is investigating valorising the spent scrubber solution, ammonium sulphate, for sale to the agricultural industry.
Ammonium sulphate is a valuable fertilizer.

Trigen Worcester Waste-to-Value Plant: Key Process Steps
2.1. Aspects Covered by this EMP The development proposal entails the construction and operation of additional Biodigesters and associated infrastructure as described above. The potentially significant impacts identified during the EIA process as being associated with the facility are as follows: Construction and decommissioning phases:
1) Natural stormwater drainage channel contamination from contaminated liquid surface spillages 2) Dust 3) Traffic and access 4) Fire, health and safety risk 5) Noise
Operational phase:
1) Groundwater and stormwater system contamination 2) Fire, health and safety risk 3) Health and safety risks and impacts on wellbeing from emissions from manure transport and storage and
digestate handling 4) Health risks from pests (flies), which can spread pathogens associated with manure storage and handling
In order to minimise any negative impacts associated with the facility, therefore, it is imperative that the lifecycle of the facility, as well as all aspects of the facility’s development (infrastructure) and operation (processing, storage, and handling) are subject the conditions set out in this EMP. The conditions directly address the identified potential impacts, in order to ensure that the health, safety and environmental risks associated with the plant can be avoided or minimised. 2.2. Map of Environmental Sensitivities Erf 4396, where the effluent digester plant is situated which is proposed for adaptation, is a heavily transformed site which has been used for industrial purposes for decades. There are therefore no sensitive areas on the site which need to be avoided. The site layout plan contained in Appendix D shows the proposed layout of the plant on the site. 2.3. Legal Framework

4. OBJECTIVES, TARGETS AND MEASURES A variety of potential impacts are associated with the operation of the biodigestion facility. A number of mitigatory measures are proposed to minimise impacts during the operational phase. It is understood that the applicant, the Trigen Group (Pty) Ltd, is responsible for any environmental rehabilitation as identified. It is understood that the applicant, the Trigen Group (Pty) Ltd, is responsible for the implementation of the recommended impact management measures throughout the lifecycle of the development; as well as being responsible for any environmental rehabilitation as identified.
- 11 - 4.1. DESIGN PHASE IMPACTS Timeframe for implementation of design phase measures: The design of the development proposal is aimed at minimisation of health, safety and environmental risks associated with the plant. These design-phase measures must therefore be implemented at the earliest stages so that construction works can proceed in line with these measures.
4.1.1. Groundwater and Stormwater System Contamination Objectives: To prevent contamination of groundwater or stormwater as a result of a spillage, tank or line leak and surface runoff of untreated effluent or acids from the nutrient dosing tank farm; or from manure storage on bare soil or uncontrolled rainwater runoff from manure. Targets: To comply with relevant codes of practice and applicable legislation with respect to prevention of pollution of natural resources. Measures: The Biodigester plant must be designed with the following measures in place:
(a) All process tanks and pipework, and the chemical (nutrient dosing) tank farm to be designed and constructed according to the relevant codes of practice, including:
i. API STD 620 – recommended rules for design and construction of low pressure tanks ii. AWWA D103 – design, construction, inspection and testing of factory coated steel bolted
tanks iii. AWWA D100 - design, manufacture and procurement of welded carbon steel tanks iv. BS2594 - specification for carbon steel welded horizontal cylindrical storage tanks v. BS2654 - manufacture of vertical steel welded storage tanks with butt welded shells vi. SANS 1476 - Fabricated flanged steel pipework, pipe and fittingsSANS310 - storage tank
facilities for hazardous chemicals) vii. BS 8007 - design of concrete structures for retaining aqueous liquids viii. SANS 10100 - the structural use of concrete ix. SANS 10162 - the structural use of steel x. SANS 10108 - the classification of hazardous locations and the selection of equipment for
use in such locations xi. SANS 62305 – protection against lightning
(b) Construction joints will be fitted with appropriate waterproof joints.
(c) Control of surface runoff in such a manner that spillages can be contained and so prevent access to the stormwater system. Please see the Stormwater Management Plan contained in Appendix G. The SWMP should be approved by the Breede Gouritz Catchment Management Agency prior to construction commencing.
(d) Leak detection: All pipework will be designed according to relevant SANS codes, and will be aboveground.
(e) Isolation valves at regular points along the system’s pipework will isolate and minimise any leaks.
(f) A daily infrastructure and equipment inspection schedule will be compiled prior to commissioning for inclusion in the EMP.
(g) The nature of the effluent and manure reticulation system through the plant, and of the various buffer and digester tanks, is that leaks will be detected on the pressure gauges and flow instrumentation.
(h) The digestion mix is slurry and therefore off-site migration is not a risk. Prompt localised leak or spill response will be adequate to prevent contamination.
(i) The manure storage unit should be purpose designed to provide adequate containment of the manure –
to prevent contact with soil and to prevent rainfall ingress. Offloading of the manure should take place within the controlled receiving bay of the storage unit.
- 12 -
(j) The storage unit design is to include reinforced concrete floors.
(k) The hard standing surrounding the manure storage unit will be designed in such a way that rainwater will be diverted away from the unit. Please see the Stormwater Management Plan contained in Appendix G.
(l) Any liquids from the manure storage unit (e.g. wash water) will flow down the sloped floor to a sump within the unit, and from there will be pumped to the Biodigester system
(m) The manure storage facility must be designed, operated and registered in accordance with the requirements of the National Norms and Standards for the Storage of Waste.
(n) In the unlikely event that the rate of delivery of manure to the storage unit exceeds the rate at which the manure is fed to the digester system, deliveries of manure will cease until the unit has adequate capacity to accept more manure.
(o) As best practice and for quality control purposes, the digestate storage area must be designed to avoid
rainwater ingress. This includes a roof, side walls and cladding, and a concrete floor.
4.1.2. Fire, Health and Safety Risk Potential health and safety impacts associated with the risk of fire and explosion are associated with methane gas storage. Associated smoke and disturbance related to with the evacuation of the site and surrounding area; risk to life and property. Objectives: To minimise risk through adequate design and operational measures. Targets: To meet best practice design and operational measures
(a) SANS10108: Classification of hazardous locations and SANS 60079-14: Explosive atmospheres electrical installations design, selection and erection must be adhered to in the design and construction of the plant.
(b) An Emergency Response Plan must be compiled for the plant. This will be developed once the final installation plan has been developed, a HAZOP study has been undertaken and all risk management issues addressed and adopted into the final scheme.
(c) The RCL facility is currently a Major Hazard Installation. Once the manure Biodigester has been
commissioned, the MHI for the plant should be updated. (d) Sufficient & suitable storage of flammables must be provided (e) Sources of ignition must be avoided wherever flammable or highly combustible material is present in the
workplace e.g.: i. Notices prohibiting smoking is displayed and enforced ii. Welding and flame cutting is only allowed under controlled conditions that includes written
hot work permits iii. Only spark-free hand and power tools are used iv. No grinding, cutting and shaping of ferrous metals are allowed using electrically driven
power tools that produces sparks
(f) Flameproof switches & fittings are to be used in the flammable atmosphere
(g) In the event of a breakdown of the CHP engines, there is an emergency flare in place. The biogas is diverted from the CHP engines to the flare.
(h) The biogas flare is designed to combust 150% of the peak biogas flow rate to avoid over pressure in the digester and biogas discharge to atmosphere.
(i) Biogas analysis and pressure monitors, together with automated flow control valves and a slam-shut safety valve, are included in the design to ensure minimal risk associated with flaring.
(j) During plant commissioning and ramp-up, RCL mains electricity will be used.

4.1.3. Health and Safety Risks and Nuisance Odours – Emissions from Manure Transport and Storage and Digestate Handling
Objectives: To avoid nuisance odorous emissions impacting on people’s wellbeing; and to minimise health and safety risks for workers due to harmful emissions. Targets: To comply with relevant ambient air quality standards and occupational exposure limits for compounds of concern. Measures: 1. Fully enclosed, moving-bed trucks should be used to transport the manure and digestate to and from site.
2. The service contract between the applicant and the logistics provider must stipulate that the provider maintains the
trucks in a sanitary condition.
3. The service contract between the applicant and the logistics provider must stipulate that incidences with the potential for road safety or nuisance impacts, such as a truck overturning, must be responded to promptly. The truck drivers should be trained in emergency response, and the logistics provider must follow an adequate spill clean-up protocol.
4. A purpose designed, fully enclosed manure storage unit is proposed.
5. Manure should be stored for a period of up to 3 days to prevent anaerobic and aerobic breakdown of the manure.
6. All surfaces of the storage unit will be cleaned regularly according to a cleaning schedule and work instruction. This will prevent leftover residue that is older than 3 days.
7. Offloading of the manure should take place within the controlled receiving bay of the storage unit. Receiving bay doors to remain closed except during a manure delivery.
8. The manure storage unit is designed to store triple the daily quantity of manure delivered: 300T storage capacity;
up to 100T daily quantity delivered.
9. There will be 2 storage lanes for redundancy. This allows for 3 days of storage time (i.e. 300T, or 600m3), so that the digester can be fed over weekends. The additional lane can also serve as redundancy if there are mechanical issues, servicing or cleaning requirements.
10. Air flow in the manure storage unit will be designed to create negative pressure to prevent fugitive emissions escaping from the open receiving bay doors.
11. PVC strip curtains will be installed at the receiving bay entrance to assist in retaining fugitive emissions when the receiving bay doors are open.
12. A standard operating procedure must be compiled and adhered to in order to ensure that opening times for the
doors are kept to a minimum. It is noted that the design means that the manure storage area where offloading is to take place is under a negative pressure so air will flow into the storage area rather than out during loading.
13. A preventative maintenance plan for the loading doors must be compiled to ensure that they operate as designed at all times.
14. An emission scrubbing system must be installed at the manure storage unit, with the manure blending tank, which
is also a potential odour source, tied in. The scrubber is to be designed as follows (please see the design schematic contained in Appendix B):
The scrubber design capacity is 150%. This has been calculated based on the volume of air to be treated; the
number of air changes required; and the air flow rate.
The air entering the scrubber system is known to be NH4-rich, and may also contain H2S.
The scrubber removes NH4 from the air with a sulphuric acid solution; and H2S- with a sodium hydroxide and sodium hypochlorite solution.
The first scrubber stage treats NH4. The treated air is then directed to second scrubber for H2S treatment.
- 14 - The scrubbing solution for each stage is sprayed into the top of a chamber, with the air entering
towards the bottom of the scrubber. The chamber contains pall rings to maximise the contact surface area between the air and the scrubber solution.
The scrubber solution collects at the bottom of the chamber and is recirculated through the chamber until
spent. The recirculation solution will be topped up with chemicals in proportion to H2S and NH4 concentrations detected in the off-gas.
The spent NH4 scrubber solution is an ammonium sulphate solution. This comprises <0.5m
3/day and
discharges to sewer, or can be sold as a fertilizer.
The spent H2S scrubber solution comprises sodium sulphate, sodium chloride and elemental sulphur. This comprises <0.05m
3/day and discharges to sewer.
With the available, conservative emissions concentrations from the manure storage unit, the air quality
specialist has indicated recommended that the scrubber system stack is to have a height of 20m to allow for adequate emissions dispersion to ensure low odour impact. During detailed design, more data, including modelling of emissions dispersion if required, should be presented to the CWDM to motivate the required stack height.
Redundancy is built in with: duty and standby pumps; and design capacity of 150%.
Maintenance and repair time is minimised using locally sourced and standardised parts.
Critical spare parts will be stored on site.
The Biodigester plant includes a repair station for all critical mechanical components, such as pumps. The plant is designed so that critical mechanical components can be removed by chain block and gantry to the repair station.
Factoring in maintenance and repair, the scrubber system is expected to have 96% utilisation (i.e. 15 days of downtime per annum).
Pressure monitoring on the gas lines in and out of the scrubbers will detect blockages in the scrubber solution delivery and sprayer system (low pressure on discharge indicates a blockage).
Access manways to scrubber chambers for easy inspection and maintenance.
Scrubber solution dosing pumps will be on a timer and manually adjusted in accordance with off-gas concentrations.
In-line and portable gas monitors to be used downstream of the scrubber chambers to intermittently check H2S and NH4 concentrations. This will assist the operator to monitor and manage dosing of the scrubber solution.
The gas monitors must be fit for purpose, i.e. must be able to operate at the emission gas temperature, moisture content and pressure; and must be regularly calibrated.
The system will be under constant CCTV surveillance, which will assist Trigen to ensure that the system is being operated correctly.
There will be an operator at the plant at all times.
A detailed SCADA system will be in place for remote system supervision.
15. The scrubber design is to allow for possible future adaptations or upgrades that may be required in order to ensure that odours are minimised.
16. The detailed design of the scrubber is to be submitted to the Cape Winelands District Municipality’s air quality officer for approval prior to plant commissioning
17. Operators at the manure storage unit must wear personal gas monitors to detect dangerous gas concentrations.
18. Breathing apparatus will be positioned at critical points in the manure storage facility.
- 15 - 19. An ammonia stripper will be installed for the treatment of the liquid fraction separated out from the
digestate during dewatering. This will enable the liquid fraction to be reused in the Biodigester system as dilution water:
The liquid fraction is heated up using heat exchangers and waste heat from the CHP’s.
Heating the liquid fraction strips the ammonia from the liquid and the nitrogen lean liquid fraction is returned
as dilution water to the Biodigester system.
The ammonia off-gas is sent to an ammonia scrubber utilising acid wash solution (sulphuric acid) in counter-current to the off-gas flow to remove the ammonia and produce ammonium sulphate as a by-product.
The ammonium sulphate is discharged to sewer.
A diagram showing the basic principles of the scrubber is included in Appendix B.
To ensure that the scrubber system operates as designed, the following design and management measures will be implemented:

OPERATIONAL PHASE MITIGATION MEASURES Timeframe for implementation of operational phase measures: The measures for minimising health, safety and environmental risk associated with operations at the new plant, will need to be implemented on an on-going basis throughout the operational lifespan of the development.
4.4.1. Fire, Health and Safety Risk Potential health and safety impacts associated with the risk of fire and explosion are associated with methane gas storage and acid storage. Associated smoke and disturbance related to with the evacuation of the site and surrounding area; risk to life and property. Objectives: To minimise risk through adequate design and operational measures. Targets: To meet best practice design and operational measures. Measures:
(a) The safety of workers is of paramount importance. All workers and managers on site must be sensitised about the safety risks that exist at the plant in terms of fires, vapour cloud explosions and the release of toxic vapours. Workers and management must be trained in the safety and emergency response procedures that apply to the factory and its premises. Regular breathalyser tests must be conducted on site among all workers and management to ensure that no worker consumed alcohol before entering the site or while present on the site. If any worker or manager fails the breathalyser test, he/she must be dismissed with immediate effect.
(b) A specific person must be appointed in accordance with Section 16 (2) of the Occupational Health and Safety Act to take responsibility, together with the appointed Chief Executive Officer, for the health and safety of all workers on site. This safety officer must have the authority to stop any work or action that may pose a health and safety threat to other workers on site.

4.4.2. Groundwater and stormwater system contamination
Contamination of groundwater and stormwater as a result of a spillage, tank or line leak and surface runoff of untreated effluent into the stormwater system. Objectives: To ensure that any spills or leaks at the site from an incident or from day-to-day storage and handling activities, are not able to reach groundwater or the stormwater system. And in the event of an incident, that prompt action is taken to remedy the cause of the spill or leak and to address any potential contamination. Targets: To comply with best practice and legislative requirements. Measures: (a) A groundwater and surface water monitoring programme should be compiled in detail in conjunction with the
Breede-Gouritz Catchment Management Agency. Based on preliminary feedback from the BGCMA, for the first two years after plant commissioning, the programme may include monitoring of nearby drainage channels during the high flow season; and sampling for the following parameters should be undertaken: pH; electrical conductivity; COD; ammonia; nitrates and nitrites; phosphates. In addition, the programme may include the requirement to sample at the existing borehole on Erf 4396.
(b) Any incident that results in ingress of untreated effluent or similar into the soil, groundwater or stormwater system must be reported to all relevant authorities, including DEA&DP and the Breede Gouritz Catchment Management Agency on behalf of the Department of Water Affairs, within 14 days. This is in compliance with Section 30 (10) of the NEMA and Section 20 (3) of the Water Act. The incident report must include the containment and clean-up procedure and the remediation procedure for the impacted area. Containment, clean-up and remediation must commence immediately.
(c) In the event of a leak, prompt response to repair the leak is required. Effluent and manure are non-hazardous. A leak should be rapidly detected and should be small in scale, given the design and monitoring measures in place. Therefore spill response media are not considered necessary. A spill should be cleaned up and returned to the relevant step of the digestion process. If this is not possible, the spill should be disposed of to landfill.
(d) There is an Emergency Response Plan in place for the existing effluent Biodigester plant. This should be updated where required to accommodate the manure Biodigester prior to plant commissioning, and should include spill and leak response procedures, as well as response to tank, line or bund failure.
- 24 - (e) Hazardous and general waste must be separated. All hazardous waste must be disposed of at
a licensed hazardous waste disposal site, with chain of custody documentation retained in the Environmental Register as proof of end recipient.
(f) A spill response kit appropriate to any chemicals stored, handled and processed at the site must be kept at the site at all times.
(g) In the event of a spill or leak, spill response according to the Emergency Response Plan must be implemented.
(h) An Environmental Register must be kept on site. The Incident and Accident Registers may be kept in the Environmental Register. Details of any incidences which may occur, as well as details on how the incident was rectified and / or remediated, must be included in the register. The register should also include chain-of custody receipts from disposal of hazardous waste; copies of any Section 30 Incident Form which may need to be sent to the authorities in the event of an incident; results of any on-going monitoring; details of complaints from neighbouring parties with respect to nuisance impacts such as noise or odours; etc. The Environmental Register should be kept updated by the designated site Safety Officer.
4.4.3. Nuisance Impacts on Neighbours Objectives: To ensure that adjacent occupants and owners are not impacted negatively by nuisance impacts such as noise and odours. Targets: To comply with authority requirements with respect to minimising and managing nuisance impacts on neighbours. Measures: (a) All windblown litter must be collected on site and may not cause a nuisance to neighbours.

the incident has occurred.
(c) Relevant legislation pertaining to allowable noise levels in an industrial area must be adhered to, including the Western Cape Noise Control Regulations.
(d) Noise proof containers must be utilised for the noisiest equipment to ensure compliance with relevant legislation pertaining to noise disturbance.
(e) Manure and digestate transport trucks shall be cleaned and sanitised regularly by the service provider. This stipulation must be included in the service contract between Trigen and the service provider.
(f) Service contracts with manure suppliers must stipulate that only fresh manure may be delivered to the Biodigester plant.
(g) Operations at the plant must adhere to the National Dust Control Regulations.
4.4.4. Hygiene (h) No recovered water is to be used in any food handling area or activity at the plant.
4.4.5. Additional design, management and mitigation measures to prevent failure of the system and minimise all impacts
Digester failure and associated impacts: 1. There will be two smaller reactors operating in parallel instead of one large reactor. This adds an element of
redundancy. Also, the plug-flow operation of the digesters means that feedstock is fed in batches which is further risk mitigation against toxicity, which could lead to biomass death.
2. The mix in the digester tanks is agitated by means of compressed biogas recycled through an intricate distribution network. This is an efficient system with minimal risk of mechanical failure.
- 25 -
3. The temperature in the digester tanks is monitored continuously. The reactions in the digester tanks are exothermic, and waste heat from the CHP’s is used to keep the digester contents at the desired temperature.
4. The design and management measures included are adequate for preventing failure of the digesters. In the highly
unlikely event that a digester tank fails, an Emergency Response Plan will be implemented. The Emergency Response Plan for the effluent Biodigester should be updated prior to commissioning to include response to tank failure.
5. There is an H2S scrubbing system installed on the gas line downstream of the Biodigester. This is already in place associated with the effluent Biodigester. The scrubber removes H2S from the gas stream before the biogas is piped to infrastructure which can be corroded, which could lead to failure over time (e.g. the CHP engines, which include steel mechanical parts). To ensure that the scrubber system operates as designed, the following design and management measures have been implemented:
Duty and standby pumps are in place for redundancy. Pumps are used alternately to ensure that a single pump is not overworked: operating hours are balanced by the operator.
Pressure monitoring on the gas lines in and out of the scrubbers detects blockages in the scrubber solution delivery and sprayer system (low pressure on discharge indicates a blockage).
Access manways to scrubber chambers for easy inspection and maintenance.
Scrubber solution dosing pumps will be on a timer and manually adjusted in accordance with off-gas concentrations.
In-line and portable gas monitors are used downstream of the scrubber chambers to intermittently check H2S concentrations. This assists the operator to monitor and manage dosing of the scrubber solution.
The scrubber design capacity is 150%.
Mechanical components have been locally sourced and are standardised for ease of replacement.
The system is under constant CCTV surveillance, which assists Trigen to ensure that the system is being operated correctly.
There is an operator at the plant at all times.
A detailed SCADA system is in place for remote system supervision.
Redundancy is built in with: duty and standby pumps; and design capacity of 150%.
Maintenance and repair time is minimised using locally sourced and standardised parts.
Critical spare parts are stored on site.
The Biodigester plant includes a repair station for all critical mechanical components, such as pumps. The plant is designed so that critical mechanical components can be removed by chain block and gantry to the repair station.
Factoring in maintenance and repair, the scrubber system has about 96% utilisation (i.e. 15 days of downtime per annum).
The digestate dewatering stage will also be designed with duty and standby pumps and locally sourced,
standardised components; and will be overseen by a plant operator at all times, as well as supervised by the SCADA system.
6. The pH of the mix inside the digester tanks is continuously monitored by means of pH probes. If the pH drops, an alarm is activated and steps will be taken to correct the pH. This prevents the pH dropping to acidic levels, which results in inefficient biogas production.
7. There will be an on-site laboratory for the regular analysis of the digestate, digestion water and waste water. Independent analysis will also be undertaken periodically.
- 26 -
General:
8. The Biodigester plant must be maintained and operated according to the design specification.
9. The effluent discharge permit currently in place at the RCL facility must be amended accordingly in consultation with the local authority.
10. The grit waste skip must be kept closed, and must be emptied regularly with the contents disposed of to landfill. 4.5. DECOMMISSIONING PHASE IMPACTS
Timeframe for implementation of decommissioning-phase measures: The measures recommended for minimising health, safety and environmental risk associated with the decommissioning of the plant, need to be implemented during the practical decommissioning of the plant. Any rehabilitation measures required will take place for the duration recommended by the specialists compiling the rehabilitation action plan. In the unlikely event that the facility is decommissioned, the construction phase management measures contained in Section 4.3 of this EMP must be implemented.
In addition, the following measures should also be implemented to minimise the health, safety and environmental risks associated with the decommissioning of the infrastructure: (a) Adequate training in emergency response situations of the contractor and construction personnel undertaking
the decommissioning activities will be carried out.
(b) Fire fighting facilities which will include hand-held fire extinguishers and a hose reel. These facilities must be approved by the local fire department.
(c) Minimisation of hot work by using alternative methods and equipment such as air driven tools, cold cutting and pre-fabrication off site.
(d) The use of appropriate shielding and screening such as blanketing with fire fighting foam and water screens to minimise fire risk.
(e) Minimisation of spark quenching by wetting down and/or using construction power tools such as jack hammers under running water.
(f) Use of gas testing at methane gas and acid storage area to ensure there are no residual emissions.
(g) A fire attendant will be on stand-by during the decommissioning process 5. IMPLEMENTATION OF THE EMP 5.1. Roles and Responsibilities, including Monitoring, Auditing and Reporting

- 27 -
(d) If the applicant fails to show adequate consideration to the EMP or the recommendations of the ECO, then the ECO may recommend to the authorities that the aspect of operations to which non-compliance relates, ceases until the non-compliance is adequately rectified.
(e) At the frequency determined by the licensing authority, the site should be audited against the conditions of the EMP and the Waste Licence by an independent ECO. The audit reports should be submitted to the DEA&DP and both the Local and District Municipality for their records.
(f) Recommended frequency of auditing: The EAP recommends biennial auditing during the operational phase, with the first audit to be conducted within six months of commissioning of the plant. The EAP recommends weekly construction phase compliance monitoring site inspections for the first two weeks of construction, with monthly site inspections thereafter. Reporting to be submitted to the authorities on a monthly basis.
(g) Audit reports must contain monitoring laboratory results, chain-of-custody receipts to show safe disposal of hazardous waste, incident reports from the environmental register, etc.
(h) Should modifications to this document be required, these must be agreed to by all parties concerned.

It is the client responsibility to ensure that all appointed parties fulfil their obligations in terms of this EMP, i.e. the implementation of this EMP is the Client’s responsibility, and the Client must ensure that all activities taking place on the site are conducted in an environmentally responsible manner and in accordance with the requirements of this EMP. Council Representative The Council Representative will be an appropriately qualified environmental officer of the local municipality. This representative will monitor compliance of this EMP by the client through the ECO. 5.2. Documentation and Record Keeping (a) List of onsite documentation
An environmental register must be kept at the site, which must include the following:
An accident and incident register;
Complaints register;
Emergency Response Plan
Site evacuation plan/maps; and
Method statements
In addition, this EMP, the Emergency Response Plan, as well as the Waste Licence must be kept at the site. The right of the public to information shall be respected in accordance with relevant legislation.
- 28 - (b) Environmental Register The environmental register should be used to record any relevant daily information related to the operations and current status of the site, including the following information:
Details of audits and inspections carried out by the ECO and/or as detailed in this EMP and follow-ups
Instances of non-conformances found in the EMP, the date of their occurrence, date of corrective action, and date of completion of preventive action
Details of chain of custody documentation
Any other relevant/pertinent daily events
The environmental register should also contain the accident and incident register and/or the complaints register.
(c) Accident and Incident Register An accident and incident register must be kept and should include the following information:
Time, date and place of the accident and/or incident
Who and what was involved
A detailed description of the accident or incident.
(d) Complaints register
A complaints register must be kept for the recording of all complaints lodged regarding the proposed biodigester plant. It is important that the complainant feels that their concerns have been listened to and that appropriate action (within reason) has been taken to address these. The complaints register must include: Detail of the complaint in clear, well-structured language Time and date of complaint and details of complainant for follow-up purposes. Name of the person who received the complaint. Description of action that was taken to address the complaint, including date and time of action. (e) Method statements Method Statements (a template for these purposes is appended to this EMP) will be required for activities that may result in significant impacts according to the ECO. These must address the following aspects:
What – a brief description of the work to be undertaken
How – a detailed description of the process of work, methods and materials
Where – a description of the location of the work (if applicable)
When – the sequencing of actions with commencement and completion date estimates
All Method Statements (MS) must be in place at least 5 working days prior to the relevant construction activities taking place and must be approved by the ECO prior to being implemented. The following MS must as a minimum be made available to address the following decommissioning related impacts:
Stormwater Management
Fire Risk Management
Waste Management
5.3. Environmental Awareness and Training a) For the construction phase, the ECO should conduct on-going Basic Environmental Awareness Training
sessions with the Contractor, his staff and subcontractors prior to any work taking place. The Contractors are required to provide a facility and interpreter (if required).
b) For day to day operations at the site, it is the responsibility of the Client to ensure that all employees and sub-contractors are fully aware of the operational procedures that must be followed in order to minimise health, safety and environmental risks associated with operations at the facility.
- 29 - 5.4. Matters Pertaining to Non-Conformance onsite
“Non-conformances” would occur when there are deviations from any of the requirements of this EMP. This may also include non-compliance with the relevant environmental regulations. During the construction phase, the Contractor is responsible for reporting non-conformance with the EMP, to the ECO. The Client and the Contractor, in consultation with the ECO must, thereafter, undertake the following activities:
Investigate and identify the cause of non-conformance;
Implement suitable corrective action (appropriate to the magnitude of the environmental impact), as well as prevent recurrence of the problem, with responsibilities assigned for both.
Non-conformances and corrective action must be recorded in the environmental register, and included in the audit reports compiled by the ECO. The Client may introduce some form of penalty system for contractors onsite if compliance with the EMP proves problematic. During the operational phase, it is the Client’s responsibility to appoint an independent ECO to audit the site once every two years. The audit report must be submitted to the DEA&DP, the DEA, Water Affairs and Rustenburg Local Municipality and must include any incidences of non-conformance and recommendations for any corrective action required. In addition, the Client, their contractors, sub-contractors and employees are legally bound by Section 24(h) National Environmental Management Second Amendment Act, Act No. 107 of 1998, which states that it is “an offence for any person to contravene conditions applicable to any environmental authorization granted for a listed activity. A person convicted of an offence is liable to a fine not exceeding R5 million or to imprisonment for a period not exceeding ten years, or to both such fine and such imprisonment” This Environmental Management Programme, when approved, constitutes a Condition applicable to an Environmental Authorisation (or Waste Licence) and any transgression would thus trigger Section 24(h) of the above-mentioned Act. The exact penalty and fines will be decided on, subsequent to consultation with DEA&DP and the local municipality. All staff working on-site must be made aware of the consequences of non-conformance.
