INTRODUCTION This Environmental Management Plan (EMP) addresses the management of environmental impacts related to the operation of a service station at Paul Kruger Street in Secunda on Erf 8403/1 of Extension 28. The document should be used as a basis for managing, mitigating and monitoring the environmental impacts associated with the pre-construction (design), construction and operational phases of the Environmental Impact Assessment (EIA) Supplementation study, conducted by SRK Consulting. The original Scoping Report and subsequent Supplementation Study will be valuable as a reference source for understanding this EMP and for placing it into perspective.
2
OBJECTIVES The primary objectives of the EMP are as follows: • •
•
To describe action plans for achieving the mitigation measures described in the EIA. To indicate responsibilities, schedules and staff resources regarding the implementation of these action plans. To highlight a monitoring programme, that will enable review of the success of the EMP and the provision of such information to the relevant decision-makers.
3
RESPONSIBLE PARTIES, SCHEDULING AND STAFF RESOURCES There are at least three role-players participating in the environmental management of the site, including: •
Sasol Oil (oil company);
•
Developer (Mr H. Kruger); and
•
Contractors and Service Providers.
This EMP must be attached as an appendix to tender documents and referred to in the tender documents as special conditions of tender. Overall responsibility for the implementation of the EMP lies with Sasol Oil. This responsibility, in some instances may be delegated to contractors in the employ of Sasol Oil for practical purposes, but Sasol Oil will retain legal responsibility. In that capacity, Sasol Oil should delegate suitably qualified person(s) with the responsibility to ensure implementation of the EMP, and will: •
Know the contents and implications of the EIA and monitor the implementation of EIA findings
• •
using the EMP and Project Aspect Register. Revise the EMP as required and inform the relevant parties of the changes. Protect the environment and rehabilitate the environment as prescribed in the EIA.
The responsibilities of the Developer during the operational phase are inter alia to ensure that:

•
All requirements of the EIA and EMP are, communicated to, understood and followed by all persons working on the project who may have an impact on the environment.
•
A procedure exists for reporting incidents and resolving any problems rapidly.
•
Keep good records relating to the compliance/non-compliance with the conditions of the authorisation. These records must be made available to the relevant authority within seven days of receipt of a written request.
The EMP will be presented to Mpumalanga DEAT (MDALA) on request. Once the authority has approved the EMP for the project, the management guidelines contained in this document will be implemented.

MANAGEMENT OBJECTIVES In line with Sasol Oil’s Safety, Health and Environmental Policy Declaration & Guidelines, the following objectives provide the framework for the environmental principles for environmental management of the project: •
As a minimum requirement, comply with all relevant local, provincial and national legislation.
•
Manage and use land, raw materials and resources responsibly in order to minimise the disturbance of the prevailing ecology.
•
Minimise the potential for deterioration of air quality during all project phases.
•
Avoid “disturbing” noise levels (an increase in the ambient noise level of 7dB (A) or more at the border of the property from which the noise emanates).
•
Minimise the use of clean water and avoid water wastage.
•
Prevent the contamination of surface and ground water as a result of the service station activities.
•
Ensure that an appropriate Emergency Procedure is in place to safeguard the environment, local community and employees.
• •
Practise the reduction and recycling of waste materials. Enhance the creation of direct job opportunities for the surrounding community and contribution of the project to the local economy, especially during labour intensive phases (construction and decommissioning).
•
Reduce the disturbance of the surrounding community from site activities to a minimum.
•
Maintain transparent relations with the Interested & Affected Parties (IAPs) (including surrounding community, authorities and employees).
•
5
Ensure that the community and employees are not subjected to increased safety hazards.
MANAGEMENT PRINCIPLES These guideline principles will form the basis for environmental management on site. Should these principles require modification or additions during the project this should be done at the discretion of the responsible person, who will ensure that any modifications are communicated, explained to and discussed with all affected parties (i.e. the authorities, Sasol Oil, the contractors and service providers, the developer and any infected party who requests this information). Environmental Management Plan: Sasol Convenience Centre, Paul Kruger Street, Secunda
3
The environmental operational procedures and environmental issues are identified and managed, under different phases of the project. The different phases are: •
Pre-construction (including design);
•
Construction Phase;
•
Operational Phase; and
•
Decommissioning Phase
5.1

Environmental Management Plan: Sasol Convenience Centre, Paul Kruger Street, Secunda
4
Proof of compliance with the SANS 10089-3 and 1535 Codes of Practice for the Petroleum Industry must be forwarded by Sasol Oil to the MDALA prior to operation.
5.2
Environmental issues to be managed Pre-Construction Phase 1. The Mpumalanga DEAT (MDALA) must be notified: •
Within 30 days, of change of ownership / developer.
•
Of any change of address of the owner / developer.
•
One month prior to commencement of construction activities.
•
One month prior to commencement of operation.
2. Ensure compliance with the conditions described in the Record of Decision. 3. Records of compliance / non-compliance with the conditions of the authorisation must be kept and be available to Mpumalanga DEAT on request. 4. If required by the Record of Decision, advertise the authorisation for one day for two consecutive weeks in two local newspapers. 5. Records of all environmental incidents must be maintained, and a copy of these records be made available to the Mpumalanga DEAT / DWAF on request throughout project execution. Construction and Operational Phases Unless otherwise indicated, the responsibilities of the construction contractor(s) and service providers will adhere to specified EMP actions for the construction phase. During the operational phase, Sasol Oil will ensure that the following actions are implemented by establishing accountability and responsibility between the different role players. These actions/measures are as follows:
5.2.1
Access control Construction Phase 1.
Ensure compliance with requirements of the Record of Decision.
2.
The Local Traffic Department must be informed at least a week in advance if the traffic in the area is affected during construction.
3.
Person and vehicle access should be restricted during construction so as to control
4.
The remote filler points on the tanks should be so situated that it is possible for the tanker
access to otherwise potential dangerous excavations and materials. to be able to enter and leave the premises without having to reverse, and can park safely when bulk fuel deliveries are being made. 5.
Movement of construction vehicles potentially impacting on urban infrastructure should be mitigated through the use of appropriate warning signs, and not entering or leaving the site during peak traffic hours.
Environmental Management Plan: Sasol Convenience Centre, Paul Kruger Street, Secunda
5
6.
The contractors must comply with the recommendations from the traffic study. Layout design should accommodate the impact on existing traffic flow patters (e.g. access points).
Operational Phase Vehicles should be able to access and exit the site as follows: 1. Left-in slip lane from the north-east for vehicles travelling south-west bound. 2. Stop control at the north-eastern end of the site, which allows vehicles to exit the site into the north-east bound lane of Paul Kruger Street. 3. Stop control for right turning traffic (and access lane) on the south-western end of the site. The lane configuration along Paul Kruger Street would allow for: (1) a lane for the main stream of traffic flowing past the site; and (2) a slip lane for traffic turning into the proposed SCC. 4. Left-out lane into Paul Kruger Street for vehicles exiting the site in a south-west bound direction. 5. Guidelines will be painted for all access and exit movements, including for the right turning movement. Ensure that this is in line with what is proposed in the SDP. 6. Consideration will be given to constructing raised islands, which are designed to prevent motorists from entering and exiting via the wrong access lane. 7. Pedestrian access from the adjoining sports and recreational facilities should be controlled.
5.2.2
Air quality Construction Phase 1.
Dust generated during site clearance and the construction phase should be mitigated through dust control measures.
2.
Vent pipes should be positioned at a point remote form all buildings and neighbouring property boundaries to mitigate the impact of vent gases from vent pipes and the interceptor chamber.
Operational Phase The impact of vent gases from vent pipes and the interceptor chamber is minimised through positioning of the vent pipes at a point remote form all buildings and neighbouring property boundaries.
5.2.3
Consultation with Interested and Affected parties (IAPs) Construction and Operational Phases Open liaison channels should be established between the Sasol Oil, the developer, the contractors and IAPs such that any queries, complaints or suggestions can be dealt with quickly and by the appropriate person(s).
Environmental Management Plan: Sasol Convenience Centre, Paul Kruger Street, Secunda

5.2.4
Effluent handling The agreement with the Local Authority to handle additional sewage and effluent from the site must be in place. Construction Phase 1. Dirty water areas must be lined by an impermeable material such as concrete to prevent infiltration and contamination of the soils within these areas. 2. Use should be made of the necessary Local Authority Services for sewage removal. 3. The site must be serviced by properly managed and maintained toilet facilities. One toilet should be provided per 1-15 staff members (male/female) on site. The contractor is to ensure that permanent on-site toilet facilities are properly maintained and are in working order. No disposal, or leakage, of sewage should occur. The Managing Contractor should verify if the necessary services are available for the operational phase. Operational Phase 1.
Clean and dirty water systems must be separated to prevent contaminated run-off from entering the surface and groundwater and soil.
2.
The effluent from the driveway area around the diesel dispensers / dispensing pumps must not flow to the street, or into watercourses or into storm water systems without first passing through a gravity-separator.
3.
All waste oils, greases, fuels etc. must be collected and disposed of in an appropriate manner off site. The contents of grease traps or other waste oil, grease and/or fuel disposal/storage containers must under no circumstances be voided to the surrounding area.
4.
All waste from the workshop must be disposed of in a suitable manner at a registered disposal site.
5.
Should an accidental spill event occur, the effluent must be contained as far as possible in the separator pit. If there is a risk that the sump could overflow (such as in a storm event) then the spilled material must be stored in a tanker or other appropriate container until it can be treated and disposed of.
5.2.5
Emergency plan Construction and Operational Phases 1.
An emergency plan should be available for major / minor spills and fire fighting at the service station during construction activities (with consideration of air, groundwater, soil and surface water).
2.
All pollution incidents must be reported to Mpumalanga DWAF and other relevant authorities within 24 hours of occurrence. Record(s) of environmental related incidents should be maintained and communicated to Sasol Oil.
3. An emergency plan should be available for major / minor spills at the service station during operation activities (with consideration of air, groundwater, soil and surface water) Environmental Management Plan: Sasol Convenience Centre, Paul Kruger Street, Secunda

Training should be provided to the staff members in the use of the appropriate firefighting equipment.
5.
There should be close co-operation with the local fire authority to ensure that they know the layout of the facility, what equipment and facilities are available, where they are located, and how they are used.
5.2.7
Illumination Construction and Operational Phases 1. No spotlight should be directed to the residential area. 2. Lighting system should not flicker or cause stroboscopic effects. 3. The receiver should not receive direct illumination. 4. The signage should not allow the light to shine directly into the properties.
5.2.8
Labour and social issues Construction Phase 1.
The criteria for and selection of labourers, contractors and suppliers for the project should demonstrate preference for the local community. Such requirements should be included in contract documents and be monitored by Sasol Oil.
2.
Contractors must ensure proper supervision of employees at all times, undertake regular inspections of the workplace, enforce the wearing of safety equipment/clothing and ensure compliance with all relevant rules and procedures.
3.
Staff should be educated as to the need to refrain from indiscriminate waste disposal and/or pollution of local soil and water resources and receive the necessary safety training.
4.
The provision and proper utilisation, maintenance and management of toilet, wash and waste facilities for staff during construction must be ensured.
5.
Machine / vehicle operators should receive clear instructions to remain within demarcated access routes.
Environmental Management Plan: Sasol Convenience Centre, Paul Kruger Street, Secunda

7.
Contractors must adhere to normal working hours and ensuring that all machinery is in a good state of maintenance to mitigate noise.
8.
Any archaeological findings during construction must be reported to the local Monument's Office.
Operational Phase 1.
Where possible, staff retrenched from existing filling stations following the start-up of the new SCC should be recruited and (re) trained by the owner and /or manager.
2.
Ensure the provision and proper utilisation, maintenance and management of toilet, wash and waste facilities for staff.
3.
Raise awareness under staff to the need to refrain from indiscriminate waste disposal and/or pollution of local soil and water resources.
4.
All employees must undergo the necessary safety, health and environmental training and wear the necessary protective clothing.
5.
Adherence to normal working hours and ensuring that all machinery is in a good state of maintenance would mitigate noise.
5.2.9
Materials handling Construction Phase 1.
Proper storage facilities for the storage of oils, paints, grease, fuels, chemicals and any hazardous materials to be used must be provided to prevent the migration of spillage into the ground and groundwater regime around the temporary storage area(s).
2.
These storage facilities (including any tanks) must be on an impermeable surface that is protected from the ingress of storm water from surrounding areas in order to ensure that accidental spillage does not pollute local soil or water resources. Additionally, cement and other potential environmental pollutants must be mixed on an impermeable substratum.
3.
The contractor must ensure that its staff is made aware of the health risks associated with any hazardous substances used and has been provided with the appropriate protective clothing / equipment in case of spillages or accidents and have received the necessary training.
Operational Phase 1.
Workers should at all times be made aware of the safety, health and environmental risks associated with all identified hazardous substances used and should be provided with appropriate protective clothing / equipment in case of spillages or accidents. Records of environmental training and incidents should be maintained.
2.
Storage of flammable stocks for sale must be in a secure area with proper fire fighting equipment and hazard signs.
Environmental Management Plan: Sasol Convenience Centre, Paul Kruger Street, Secunda

5.2.10 Noise disturbance Construction Phase 1.
The construction contractor must ensure that construction and other noise generating activities are restricted to normal working hours, unless otherwise approved in consultation with IAPs.
2.
The presence of work force may create noise, which should be mitigated by using as far as feasible local work force and ensuring that equipment is in a good state of maintenance, during construction and operational phase.
3.
The Managing Contractor during construction must ensure the correct layout of the site to address the potential noise impact from the car wash facility.
Operational Phase 1. Staff should not make excessive noise especially during late hours. 2. Equipment used in the operation of the facility must be kept in good state of maintenance so that noise is minimised.
5.2.11 Natural / Resource consumption 1. Water volumes used must at all times remain within permit conditions and the developer must ensure that there is always sufficient capacity available in the event of a fire 2. Whereas it is noted that the facility was not designed to meet the requirement of certification under the International Standards Organisations standard ISO 14001 on sustainable use of energy and water, and that it would probably not be economically viable to expend large capital amounts to ensure compliance with ISO 14001, certain principles embodied in those standards are worth noting and should be considered for implementation where possible: •
Efficiencies in the use of energy can be made in the areas of building, equipment and systems efficiency: less and cheaper energy for the same task.
•
Ensure that sufficient metering systems are installed to be able to monitor the use of energy and water throughout the development.
•
Match the use of resources to changes in time of day, day of week, season, occupancy and weather conditions.
•
Be aware of development in existing and new technology that will provide increased energy and water efficiency.
•
Good training is probably the best investment in terms of making energy and water savings. Empower front line employees, they can make the difference.
5.2.12 Soil Construction and Operational Phases 1.
Stockpiled soil should be protected by erosion-control beams if exposed for a period of greater than 14 days during the wet season.
Environmental Management Plan: Sasol Convenience Centre, Paul Kruger Street, Secunda
10
2.
Soil stockpiles should be located away from drainage lines, watercourses and areas of temporary inundation.
3.
All soil excavated during construction must, where practical, be separated into top- and subsoil.
Subsoil must be used for backfilling and topsoil for landscaping and
rehabilitation of disturbed areas. 4.
On completion of the backfilling of pipe or cable trenches, the topsoil should be replaced
5.
Where topsoil has become mixed with subsoil or is not up to the original standard,
and the ground restored to its former condition, e.g. grass, artificial surface, etc. fertiliser or new topsoil should be provided by the contractor. 6.
Sensitive or high-use areas of the site must be paved to manage the impact of the operations on the ecology of the site.
Operational Phase Where contamination of soil is expected, analysis must be done prior to disposal of excess soil to determine the appropriate disposal route. Proof from an applicable waste disposal site where contaminated soils are dumped should be forwarded to the MDALA.
5.2.13 Solid waste management Construction Phase 1. In general, no littering, discarding or burying of any materials are allowed on site and roadways and sidewalks shall be left clear of waste materials. 2. All waste material must be contained and disposed of according to the relevant legal requirements. 3. Waste must be stored in such a manner that no pollution of the environment occurs at any time. 4. All domestic waste generated must be disposed of in a proper manner at the Local Authorities Municipal Landfill site (i.e. no burial on site). 5. All accumulated and surplus material must be disposed of in a suitable place and manner to prevent translocation of invasive plant species, modification of drainage and contamination of surface water. 6. Hydrocarbon (oil, diesel, petrol) waste as well as all hydrocarbon contaminated material must be regarded as hazardous waste and separated from general waste. 7. Spill cleanup kits and absorbent material must be kept on site to assist in immediate cleanup of any hazardous material spills 8. All building rubble must be either: •
removed from site and disposed of at the Local Authorities Municipal Landfill site, subject to all relevant regulations and approval by the Managing Contractor; or
•
temporarily stored in a clearly demarcated area on site for future use.
Operational Phase 1.
All waste material must be contained and disposed off according to the relevant legal requirements.
Environmental Management Plan: Sasol Convenience Centre, Paul Kruger Street, Secunda
11
2.
All domestic waste generated must be disposed of in a proper manner at the Local Authorities Municipal Landfill site.
3.
Any hazardous waste (this will need to be clarified and explained to the developer) generated must be disposed off at an appropriately classified waste site (unless it is to be recycled by approved methods). In all cases proof of safe disposal should be obtained and kept.
4.
In general, littering, discarding or burying of any materials must not be allowed on site.
5.
In the event of any spill requiring the use of absorbent materials during clean-up operations, contaminated material is to be disposed of at an appropriately registered and classified waste site. The resulting chain of custody documentation is to be retained on file together with a record of the spill details. This should be made available for inspection by the relevant authorities whenever required.
9. A waste management inventory must be compiled during the operational phase to include all waste types generated on site. 10. Waste management procedures stipulating hazard classification, separation, storage, handling, transport, recycling, reduction strategy, cleanup and disposal requirements as well as personnel responsible for each of these aspects, must be developed and kept on site. All employees must be trained with regard to hazardous waste procedures. 11. Waste management procedures must conform to the DWAF Minimum Requirements for waste disposal by landfill. 12. As a minimum requirement, all hazardous waste must be separated and recycled / disposed of according to the DWAF Minimum Requirements for the Handling, Classification and Disposal of Hazardous Waste. Safe disposal certificates of hazardous waste are to be obtained and kept on site. 13. Spill cleanup kits and absorbent material must be kept on site to assist in immediate cleanup of any hazardous material spills. 14. Environmentally friendly degreasers for washing and cleaning and bioremediation of contaminated soils must be used where practicably possible. 15. Suitable on-site ablution facilities must be provided during the construction and operational phases to cater for all personnel and customers using the site.
5.2.14 Rehabilitation Once construction is completed, the contractor must ensure that all redundant construction materials and waste are removed from site and disposed off in an appropriate manner.
5.2.15 Underground Storage Tanks and Equipment Construction Phase 1.
The Managing Contractor to ensure that, at locations where conditions of high ground water or flood water are known to exist or likely to occur, the tank is safeguarded against movement or floating by means of a reinforced concrete slab cast on top of the tank or by
Environmental Management Plan: Sasol Convenience Centre, Paul Kruger Street, Secunda
12
means of concrete saddles. The permeability of soils must be taken into consideration when installing the tank(s). 2.
Where required by the Local Authority, the tanks must be installed in brick lined or concrete pits.
3.
The Managing Contractor to ensure that the design include:
A filler box, which can contain the contents of a bulk delivery vehicle, discharge hose.
Earthing and snap-tight-quick-coupling for loading of material into tanks to minimise risk of fires and prevent spillage and loss of material.
An overfill protector fitted on the tanks.
A leak detector on all submersible pumps that automatically checks the integrity of the pipework on the pressure side of the pump.
That the pipelines do not retain product after use and no joints are made underground.
4.
The Managing Contractor must ensure that the underground storage tanks are thoroughly inspected prior to installation for fracture and damage and that the inspection authority has issued test certificates. Leak and pressure tests must be conducted on tanks and pipelines to ensure integrity prior to operation and the inspection authority must issue pressure test certificates. An Emergency shut-off valve must be supplied between the supply pipeline and dispenser inlet.
5.
A monitoring well must be placed at each corner of the excavation for each underground tank prior to backfilling. In sensitive areas, a plastic sheet, which slopes towards the monitoring wells, must be provided below the tank.
6.
Sasol Oil to ensure that a groundwater-monitoring plan is in place prior to the initiation of construction activities on site. This plan should address a strategy for the management of any groundwater contamination detected as part of the groundwater monitoring strategy, and should include the frequency of monitoring, as well as details of stock reconciliations.
Operational Phase 1.
Regular monitoring (three-monthly) of the monitoring wells must be undertaken to prevent pollution. Records of monitoring must be kept and made available to the Mpumalanga DEAT / DWAF on request. Should contamination be detected, monitoring must be extended to the monitoring boreholes as identified during the hydro census. If contamination is detected in the extended borehole survey, a rehabilitation plan must be compiled and executed.
2.
Monthly stock reconciliations must be taken and reported monthly to Mpumalanga DWAF.
3.
The leak detectors must be regularly tested and records kept.
4.
All machinery must be maintained in good working order as to prevent soil or water pollution from oil, fuel or other leaks.
Environmental Management Plan: Sasol Convenience Centre, Paul Kruger Street, Secunda
13
5.2.16 Visual Impact Construction and Operational Phases 1. During construction, the contractor must provide a sufficient fence around the site and storage spaces to visually screen off these activities from the surrounding areas. 2. There should be a planted landscape that would reduce dust creation and which will only start in terms of establishing and retaining long-term ecological values on site. Subsequent management of the scheme will either remove potential ecological value or could substantially enhance it. 3. Removal of invasive alien species must be undertaken on continuous basis.
5.2.17 Water issues Construction Phase 1.
The Managing Contractor must ensure that impediments to natural water flow is avoided wherever possible, or if unavoidable, be allowed for in the design by means of appropriately sized and positioned drains, culverts etc.
2.
The Managing Contractor must ensure that water use remains at all times within the permit conditions and that there is always sufficient capacity available in the event of a fire.
5.2.18 Removal/replacement of old fuel tank Decommissioning phase 1. Contaminated metal must be steam-cleaned prior to disposal.
Routing of effluent
dependant on contaminants. 2. If any metal, including piping, have future value it may be moved, after cleaning, to a storage area for redundant materials. 3. Reference to Sasol Oil’s existing procedure for the disposal of metal to the scrap metal dealer. 4. On the day of excavation, the site engineer, contractor and environmental consultant (contamination expert) must be present either as the tanks are being removed or immediately afterwards. 5. The area to be excavated must be cordoned off with red danger tape and no smoking signs displayed around the site. 6. All fuel inside the tank must be removed and the tank degassed, with the site then excavated to expose the tank. In order to ensure the tank is not damaged during excavation especially in areas of limited space, a small backactor must be used or the area must be manually excavated, with the removed soil stockpiled in a demarcated area on site. 7. All other electrical, stormwater or water pipelines must be located prior to excavation to ensure they are not damaged in the excavation process. All pipes and vents connected to the tank must be disconnected and sealed before the tank is removed. 8. If there are no suspected leaks or contamination, the new tank can be installed. Environmental Management Plan: Sasol Convenience Centre, Paul Kruger Street, Secunda
14
9. If a leak is suspected, soil samples must be taken from a number of points in the excavation as well as from the stockpiled soil. Water samples must also be taken if there are free-standing pools in the excavated pit. Background soil and water samples must also be taken off-site. 10. The pit must be left open while the samples are sent to an appropriate laboratory for analysis. Should the analysis indicate the soil to be contaminated, soil must be removed from the pit until all of the contaminated material has been removed. Contaminated water must be pumped out, collected and disposed of in an appropriate manner. Further soil samples must be taken and sent for analysis with the process repeated until analysis shows contamination to be within acceptable levels. 11. The contaminated soil must be stockpiled separately and remediated on site or removed to an appropriate landfill site. 12. The new tank can then be placed in the existing hole. 13. The removed tank will be loaded onto a flat-bed trailer and taken to the contractor’s storage yard or to a storage area designated by the Sasol Oil. The tank will be flushed to remove any remaining residues with the flushed water either stored for future flushing or processed to remove the fuel.
