Best Practice Environmental Management (BPEM) Siting, Design, Operation and Rehabilitation of Landfills • Groundwater and leachate management • Landfill gas management • Management of surface water (including stormwater) • Operational considerations to reduce amenity impacts (e.g. noise, odour, litter, dust and vermin) • Rehabilitation and aftercare

4.3 Community engagement Summarise any public consultation that has been undertaken or planned PWM is committed to actively consulting with the community as part of this WA application. Prior to submitting the application, PWM has undertaken the following engagement activities:

• Mapped relevant stakeholders and recruited (through invitation and advertising) a Community Reference Group (CRG).

• Developed a website for easy and open access to information about the development (http://www.peninsulawaste.com.au/)

• Engaged with the CRG to communicate the proposal including the rationale for the landfill, its benefits, information on environmental issues and mitigation measures.

• Heard and acted on the initial concerns of the CRG and others regarding fire management at the site. PWM has engaged the services of TerraMatrix to prepare a fire management plan for the site.

Following submission of the WA application, PWM will continue to engage with the CRG and the wider community to address concerns as they are raised. This would likely include advertising, a letterbox drop and potentially a “drop-in” information day to invite feedback from residents and the broader community. Feedback from stakeholders will be evaluated in consultation with the CRG and the proposal would be amended as far as is practical to accommodate concerns raised. Information would then be provided back to the community regarding any revisions to the WA application and the review and approvals process (including timeframes).

PWM will continue to engage with the community during construction and operation of the landfill to ensure their concerns are heard and acted upon appropriately. Indicate any issues that have been raised Bushfire management. As a result of the initial community consultations, PWM engaged Terra Matrix to prepare a bushfire fire management plan for the site. The recommendations of this plan have been included in the site design and executive summary report. Consultation will also be conducted with the Country Fire Authority.

attachment 1 Mornington Peninsula Regional Waste Management Group. • Review of available information on Australian and international landfill management including UK

Environment Agency LFTGN series of documents and case-studies of previous applications of the liner technology.

Explain why waste generation and resource use cannot be avoided or minimised Landfill gas (LFG) and leachate production cannot be avoided in operating a putrescible waste landfill; however they will be managed throughout and beyond the operational life of the landfill. PWM have undertaken -specialist studies for liner design, gas management, leachate and water management to ensure best practice is achieved and impacts are minimized throughout all phases of the landfill. Amenity impacts (e.g. litter, dust, odour and noise) are not predicted to be significant due to vigilant management and monitoring procedures and abatement protocols; the Peninsula Landfill will operate a management system in accordance with the EPA guidelines to ensure impacts are avoided or reduced where total avoidance is not possible. The site has good buffer distances, and the landfill cell is further concealed due to the local topography. The landfill has been designed to reuse surplus local resources: stone removed for slope stability works will be reused in the groundwater collection system and sump, leachate collection system and sump and the northern bund; The reinforced earth wall portion of the liner will use overburden from the adjacent Hillview quarry. Waste generation and resource use is discussed further in the Executive Summary Report included with this application. Explain options considered and why this process is considered best practice Quarry Rehabilitation: The site currently contains an unsightly former quarry, and is significantly weed infested. The proposed landfill provides an opportunity to beneficially reuse the former quarry, and to rehabilitate the site.

Landfill Design: The landfill has been designed to meet the specification of the BPEM wherever practicable. When specifications have not been met the performance requirements of the BPEM have been met or exceeded. The base, lower wall liner and cap is BPEM compliant.

The performance of the upper liner is in excess of BPEM requirements. To allow for the use of locally available materials, the permeability of the leachate collection aggregate is less than specified within BPEM. However, the required performance standard is exceeded by increasing the thickness of the leachate drainage layer to 2.1 m (0.3 m is required by BPEM) and maintaining a steep hydraulic gradient (average approximately 40º compared to BPEM minimum of 3º).

Groundwater protection measures in addition to those required in BPEM have been included in the design are:

• An additional 1 m of clay fill beneath the compacted clay liner will provide supplementary hydraulic control and additional dispersion and retardation of potential contaminants

• Groundwater extraction from directly beneath the cell and pumped to a retarding basin with periodic testing. This will maintain groundwater typically 4 m below the waste mass, and provide an early detection should there be leakage of the liner

• The permeability of the clay at the base is specified as 5 x 10-10 m/s, half an order of magnitude lower than required by BPEM and will further reduce the potential for leachate seepage from the landfill.

• Engineered steep sided lining system (including 2.1 m reinforced soil block drainage layer which will allow lateral leachate movement to percolate to the base for collection and allow efficient gas extraction of lateral gas movement using extraction infrastructure installed in this media).

Leachate Management: The leachate collection system will be constructed on the base of the engineered landfill lining system. This layer will permit the collection and rapid extraction of any leachate entering the cell and prevents the accumulation of leachate head on the base lining system. Extensive leachate and groundwater monitoring will be completed throughout and following closure of the site to ensure compliance standards are met. The leachate collection drain will be twice as thick as required by BPEM. Rain falling within the quarry but outside the landfill cell will be directed behind the liner to the groundwater sump to reduce leachate volumes. Landfill Gas Management: Staged LFG extraction is considered most suitable for ongoing gas management at the site, due to the depth of the quarry. A primary horizontal collection system will be installed in the waste


7

mass along with a secondary system in the permeable soil block walls. Vertical extraction wells are included in the design as a contingency measure, and will be installed if required. LFG will initially be flared, followed by gas engines with electricity generation as soon as it becomes economically viable. Extensive sub surface and surface LFG monitoring will be completed throughout and following closure of the site to ensure compliance standards are met.

Landfill Operation: The site will operate in accordance with its License requirements incorporating performance requirements set out in the EPA Landfill BPEM and Landfill Licensing Guidelines. Procedures for will be implemented for waste acceptance and placement; daily cover and compaction; environmental monitoring, auditing and reporting; training and supervision, and emergency response and abatement.

Protection of Surface Waters and Groundwater: A best practice, BPEM compliant liner will be installed to control releases from the landfill cell. Groundwater and surface water pumped from beneath the liner will be regularly tested for early indications should there be leakage of the liner. This combined groundwater and surface water will be passed through wetlands for nutrient and turbidity treatment prior to release to Sheepwash creek. An aging pipe directs surface water from the west of the quarry to the low point of the site. This will be replaced by a retarding dam and high capacity pipe to protect the landfill from flooding during periods of extreme rain.

Protection of Amenity: The site will operate within the bounds of its environmental license. Operational controls will be put in place to ensure emissions of dust, odour and litter and the colonization of vermin and pests is managed. Such controls include: efficient LFG and leachate management, daily covers, progressive rehabilitation, movable litter screens, waste compaction, narrow tipping faces and a full program of monitoring including triggers and contingencies for action.

Rehabilitation & Aftercare: Progressive rehabilitation of the landfill will be conducted throughout the operational phase as far as is practicable. Rehabilitation and aftercare for the site following closure will be in accordance with the appropriate post-closure statutory regime requirements imposed by the EPA (currently a Post-Closure Pollution Abatement Notice (PCPAN) and the landfill BPEM). Prior to the license being surrendered, a rehabilitation and aftercare management plan will be developed to ensure the rehabilitation objectives of the BPEM are addressed. It will also consider appropriate longer-term monitoring of the site that might be required. In accordance with BPEM requirements, groundwater will continue to be extracted from beneath the landfill for up to 30 years post closure. Leachate will also continue to be extracted from the landfill for up to 30 years post closure. Please refer to Sections 5, 6, 8 and 9 of the Executive Summary Report included with this application for further information on best practice design and operation of the landfill. Use of Local Resources: The landfill has been designed to utilise local resources during construction to minimise its environmental impact. Quarry safety rehabilitation works require the removal of large volumes of rock from the northern quarry wall which would provide suitable rock for the northern bund wall, groundwater drainage layer and leachate drainage layer. Existing stockpiles of crushed rock left over from the former quarrying and processing remain immediately north of the quarry, which will also be reused during cell construction.

The adjacent quarry, 1.3 km to the west, has suitable stockpiled soils sourced from the removal of the overburden of the quarrying operation and also produces suitable crushed rock and granular fill products. It is proposed that the majority of the granular fill and clay for the lower side lining will be sourced from the Hillview quarry overburden. Other waste soil streams tested from Hillview Quarry are suitable for the general engineered fill proposed in the base of the landfill.

5.3 Integrated environmental assessment Indicate any areas where there are competing environmental demands The Mornington Peninsula Regional Waste Management Plan recognises that even with improvements in recycling, a replacement site for the Rye landfill is necessary. While the Mornington Peninsula Region diverts more than 50% of waste from landfill, there still remains a requirement for a landfill to manage wastes that cannot be reused or recycled. Alternate waste treatments (AWT) are currently not considered to be economically viable with the majority of domestic waste streams being separated at kerbside and then managed appropriately. As technology and markets increase AWT may become a more viable option in the future; these will be assessed on an ‘as needs’ basis going forward and in line with the Mornington Peninsula Regional Waste Management Strategy.

In addition to servicing the needs of the Mornington Peninsula Shire, the Peninsula Landfill will be able to service adjoining municipalities on the Nepean Peninsula. In the absence of any new approvals, by 2020 the only site capable of accepting municipal waste to the east of Melbourne will be the Hallam Road landfill. The Hallam Road landfill has a finite capacity and increase in the filling rate would reduce the life of that site.

Without additional landfill capacity in the east then additional transport of municipal waste to the west of Melbourne will be required, with associated additional costs and environmental impacts.

Indicate how you will determine net environmental benefit in these areas The development of the Peninsula Landfill will provide a net environmental benefit over the course of its life. The costs associated with its long-term management (in both operational and post-closure phases) are off-set by its availability to receive high volumes of waste from the expanding local community in this part of Victoria rather than for it to be distributed by road to sites across the state.

The completion of the Peninsula Link freeway in 2013 will mean that the Peninsula Landfill will be approximately 30 minutes by road to the intersection of Eastlink and the Monash freeway meaning kerbside collection vehicles from the municipalities of Kingston, Frankston and Casey could readily access this site. The population of these three municipalities is more than 500,000 with the City of Casey as one of the fastest growing municipalities in Victoria, and both Mornington Peninsula and Frankston are also forecast to continue growing.

It is also envisaged that electricity generation will commence at the site when economically viable; further increasing the net environmental benefit of the site over the course of its life.

5.4 Choice of process and technology Process or technology Advantages Disadvantages Groundwater management

• Groundwater will be extracted during landfill operations to keep groundwater level at least 2m below waste mass.

• Energy will be consumed for groundwater pumping.

Liner • Overall the design of the proposed liner exceeds BPEM requirements.

• Staged installation due to quarry depth and steep sidewalls.

Leachate extraction • System enables easy removal of leachate, monitoring, sampling and leveling of leachate.

• Higher suction pressure is required to extract leachate from the base of the quarry.

• Restricted maintenance access of leachate system during later stages of filling.


9

Gas extraction • Early gas management • Combined horizontal and vertical gas

extraction will improve the ability to recover gas over the life of the cell as height increases and waste settles.

• Soil block wall (with gas extraction infrastructure installed) inside the perimeter of the cell will enable any lateral gas movements to be collected an extracted more efficiently.

• Greater costs are associated with sacrificial systems

• Restricted access for maintenance of buried gas manifolds.

Capping • BPEM Compliant cap design with good understanding of performance and management requirements.

• Active post closure management required.

5.5 Choice of location and layout Location or layout Advantages Disadvantages Existing quarry hole • Available airspace for landfilling in the

region. Site has previous industrial use and does and is not being sited on virgin ground.

• Viable option for rehabilitation of the quarry.

• Deep, steep sided walls require preparation and steep-sided liner system. This will have significant cost impacts for the project, but is unlikely to cause detrimental environmental impact.

location • Sited near to major road infrastructure allows easy access for most municipalities of the eastern fringes of Melbourne and is able to accept wastes from these growing areas of Victoria.

• Site topography is such that management of surface waters will need to be managed to a greater degree than would usually be required. This has been accounted for in the design of the landfill.

Environs and buffer distances

• Maintains naturally expansive vegetated buffers to minimize any amenity impacts

• Able to service the communities waste disposal requirements following closure of the Rye landfill.

• Nearest residential receptor is located approximately 480 m away from the landfill cell.

• Buffer is 20 m short of the BPEM recommended 500 m for a landfill of this type.

Infrastructure • Serviced by existing roads capable of heavy truck loads.

• Limited surface water management infrastructure is present already at the site.

• Upgrades will be required to the weighbridge, storm water, site amenity infrastructure and perimeter roads.

• Sewer will need to be extended in later stages of operations to dispose of leachate.

Mornington Peninsula Regional Waste Management Plan

• Replacement landfill for existing Rye landfill is required – Peninsula landfill has been confirmed as the long-term replacement.

• None.

Notes 1. UK Environment Agency Landfill Technical Guidance series, LFTGN 03, Guidance on the management of landfill gas

7.2 Discharge to surface water Provide reasons for any discharge to water (rather than to sewer or to land) Groundwater abstraction from the base of the quarry is required to maintain groundwater at least 2 m (and


11

typically 4 m) below the base of the waste and induce an inward hydraulic gradient similar to current conditions. Surface (rain) water within the quarry, but outside the cell will be directed behind the liner to the groundwater sump. Extracted surface water and groundwater will be discharged in a controlled manner to Sheepwash Creek; the expected quality and volume of this water is such that discharge to surface water is the most viable option. Prior to its discharge, groundwater will be pumped into a retarding basin then wetland system for treatment. Periodic water quality testing will be completed at the discharge point to the wetland and the discharge point to the creek. As a contingency measure, should leachate be detected in the groundwater sump, during periods of ‘low flow’ the resulting low volumes of extracted groundwater can be directed to the leachate tanks. Storm water diverted away from the landfill will also be managed and discharged in this manner. Rate of discharge to water; litres per day Indicate water quality or treatment level Discharge to surface water will be proportional to rainfall. During periods of low rainfall, water will be discharge water will be predominantly groundwater (0.6 L/s), which could increase to almost 50 L/s for a 1 in100 year storm event.

• Water quality monitoring will be completed at the discharge point to the wetland system and at the discharge point to the creek.

• Periodic upstream and downstream measurements of water quality in the creek will be collected to monitor this receiving environment.

• Water will be treated by wetlands prior to discharge • Groundwater sump monitoring and bores sampling to

monitor quality of the groundwater

7.3 Discharge to land Rate of discharge or deposit to land, Types of waste and level of treatment litres/or tonnes per day e.g. secondary or tertiary Waste accepted is likely to be in the region of: • Approximately 50,000 tonnes in the first year, • Approximately 100,000 tonnes in the second year • 150,000 tonnes of waste per annum thereafter. All wastes will be placed in engineered cells in accordance with site licence.

Accepted waste is expected to be: • Putrescible waste; • Solid inert waste; and • Asbestos of domestic origin. Waste is to be compacted to a density of 1 tonne per metre cubed (on average).

For reuse, demonstrate that the proposal will meet EPA guidelines Not applicable Provide the reasons for any discharge to groundwater and indicate segment It is not proposed to discharge substances to groundwater.

100 m (as provided in Section 5, table 5-2 of EPA BPEM publication 788.1 (EPA, 2010)

Notes Separation distances and siting of the landfill is considered in Sections 2 & 4 of the Executive Summary Report included with this application.

8.3 Management system Explain the system that will be used to manage environmental risk Environmental risk will be managed in accordance with the site environmental licence, EPA publication 1323.2 Landfill Licensing Guidelines (EPA, 2011) and EPA BPEM Publication 788.1 Siting, Design, Operation & Rehabilitation of Landfills (EPA, 2010).

The preliminary environmental risk assessment will be finalised based on the site-specific risk register completed for the site and this information used to finalise the preliminary environmental monitoring program. The Peninsula Landfill will also be subject to all of the environmental auditing rigors described in the EPA Landfill Licensing Guidelines (EPA, 2011) to demonstrate to the community that it is designed, constructed and operated appropriately.

Monitoring of the operations and impacts is integral to the management of the Peninsula Landfill. The monitoring program will assist the site operator in demonstrating to the community and the EPA that it is in compliance with its Licence. Specifically the environmental monitoring program will:

• Address the findings of the risk assessment • Ensure that all roles and responsibilities are allocated. • Prescribe the required environmental performance standards and the procedures for their achievement. • Provide locations, frequency and procedures for monitoring • Provide trigger points for action and contingencies for failures • Prescribe the requirements for record keeping and reporting

It is envisaged that the risk assessment, monitoring plan and Audit program will form key documents of a wider Environmental Management Plan (EMP). The EMP it will be the umbrella document for all other site-specific procedures, including:

• Occupational Health and Safety (OHS) • Waste acceptance criteria • Site maintenance. • Onsite signage • Stormwater management • Site supervision and training


13

• Daily covers • Site security • Emergency planning • Site vehicles (including traffic management) • Fire prevention & management • Waste placement and segregation • Site plant (including weighbridge

maintenance, wheel-wash facility) • Complaints procedures

Summarise the options considered to avoid or minimise solid waste Not applicable – waste is not generated at the site. Explain why the chosen option is best practice Not applicable – waste is not generated at the site. Indicate where these wastes will go Landfill waste placement will be in a series vertical lifts placed across the entire area of the quarry. To protect infrastructure such as LFG extraction pipes and for geotechnical stability of the landfill liner, it is proposed to initially mound waste in the central portion of the landfill, whilst constructing the side liner around the edges. When the liner is completed and approved the area between the waste and the liner will be filled as soon as possible. Where practical, this filling will be done with fresh waste, however it could also be achieved by moving the placed and mounded waste. The planning and sequencing will be confirmed during the detailed design, using the following general principles: • Filling will occur in 4 m high lifts to provide geotechnical stability for the steep side lining. • Landfilling in the northern portion of the landfill will be completed first, to the extent practicable. This will

allow progressive rehabilitation of the site, and reduce leachate generation (as cell capping commenced earlier) and visual impacts.

I. ENVIRONMENTAL MANAGEMENT I1. Non routine operations Outline the steps taken to identify potential process upsets or failures A preliminary assessment of the environmental risks associated with operation of the proposed landfill has been completed to assist in preparation of the Works Approval. The preliminary risk assessment has been conducted in general accordance with:

• EPA Publication 1321.2 (2011) Licence Assessment Guidelines - Guidelines for Using a Risk Assessment Approach to Assess Compliance with Licence Conditions.

• Environment Agency (UK) Guidance on the Management of Landfill Gas, LFTGN 03 (September 2004). This method is referred to in Appendix 2 of the EPA Victoria Landfill Licensing Guidelines, Publication 1323.2 (EPA, 2011).

• International Standards Organisation ISO31000: Risk Management – Principles and Guidelines (AS/NZS ISO31000:2009)

The preliminary risk assessment has identified and ranked risks and identified the appropriate operational controls and required monitoring for the following environmental segments: • Aesthetics (Litter and Dust) • Land (contamination of) • Vermin • Groundwater (including leachate) • Odour • Vegetation • Noise • Landfill Gas • Surface water (stormwater runoff)

Outline approach to identifying best practice in managing these environmental risks Review of appropriate Victoria, National and international guidelines and standards for risk and contingency management.

Type of process upset Potential environmental Measures to reduce

impact likelihood and impact Aesthetics – litter • Windblown litter being blown

beyond the boundary of the landfill and potentially entering surface waters onsite and offsite. Causing a nuisance and being unsightly and potentially affecting flora and fauna at the site.

• Progressive covering of wastes (daily cover) and maintaining sufficient sources of cover

• Boundary litter fences • Relocatable litter screens • Sheltered tipping face on windy days

(provided by the natural protection of the deep quarry)

• Monitoring for forecast windy weather. • Visual inspections and litter pickers as

required • Complaints response procedure

Aesthetics – dust • Vehicle traffic, waste tipping and placement causing dusts and ambient air emissions to onsite workers and offsite human receptors

• Dust suppression at the tipping face and roads.

• Sealed roads from site entry to gatehouse

• Reduce stockpiling of, or cover, dust-prone materials

• Monitoring for forecast windy weather. • Regular monitoring • Complaints response procedure


23

Vermin (birds, rodents and pests)

• Impact of rats, pests and in particular birds on humans and infrastructure at, and in the vicinity of the landfill.

• Bird frightening techniques such as “Bird Frite”

• Progressive covering of wastes • Maintenance of daily cover • Removal of stagnant standing water • Baited traps • Periodic surveys

Odour • Odours generated from waste delivery and placement (truck movements)

• Odours generated from fugitive emissions of LFG.

• Extracted leachate to be stored in tanks

• Safe operating procedures for leachate treatment and disposal

• Sufficient daily cover and narrow tipping face on windy days

• Monitoring for forecast windy weather. • Regular monitoring • Complaints response procedure

Surface Water • Discharge of leachate from waste or treatment system to surface water environment either from surface run-off or via groundwater discharge

• Discharge of sediments to surface water environment from surface run-off.

• Storage dams • Maintenance of diversion drains and

earth bunds • Sufficient capacity in receiving

settlement lagoons and wetlands. • Regular monitoring and safe disposal

of leachate ensuring sufficient leachate storage capacity

• Leak detection programs for leachate extraction system

• Appropriate bunding for onsite storage of fuels

• Safe working procedures and practices

• Availability of spill kits. • Potential to develop sewer

infrastructure at the site at the outset of the landfill development to ensure sufficient leachate/contaminated water disposal capacity rather than during the initial years of operation.

Land (contamination of) • Unforeseen discharge on leachate or fuels into the unsaturated zone due to process failure i.e. spillage or leachate extraction (pipework failure at surface level) failure.

• Monitoring of the leachate system • Regular maintenance of the leachate

system • Adequate capacity for leachate

storage • Appropriate signage • Waste acceptance protocols/regular

tipping face inspections • Appropriate bunding for bulk storage

of fuel and chemicals • Safe working and material handling

procedures • Availability of spill kits


24

Groundwater (including leachate)

• Discharge of leachate to groundwater (offsite and onsite) in the unsaturated zone due to extraction system failure.

• Discharge of leachate to groundwater (offsite and onsite) in the unsaturated zone due to landfill liner failure.

• Discharge of leachate to surface water in the unsaturated zone due to landfill liner failure.

•

• Engineered base and sidewall liner system will comprise a minimum of 1 m thick compacted clay and HDPE geomembrane. Clay base specified as 5 x 10-10 m/s (half an order of magnitude lower BPEM requirements).

• leachate collection system • A 2.1 m thick geogrid reinforced soil

buttress with sufficient permeability to allow any lateral leachate movement to percolate to the base of the cell and into the leachate extraction system.

• A groundwater extraction system will be installed to maintain groundwater at least 2 m and typically 4 m below the base of the waste. Rain falling within the quarry, but outside the landfill cell, will be directed beneath the landfill liner to the groundwater extraction system.

• The groundwater extraction system is sized to prevent buoyant uplift of the cell liner for a 72 hour 1 in 100 year rain event near the start of site operations (when the landfill cell is smallest, thus the non-cell catchment area is greatest and the mass of waste is the least).

• Two (2) groundwater pumps are to be installed with redundancy such that each pump would have sufficient capacity to control the groundwater level.

• Maintenance of adequate capacity for leachate in holding tanks.

• Bunding of chemicals and availability of spill kits.

• Safe working procedures. • Potential to manage low yields of

extracted groundwater as ‘leachate’ and be disposed under the appropriate trade waste agreement to prolong the life expectancy of the wetland system or if impacts to the creek are observed.

• Potential to develop sewer infrastructure at the site at the outset of the landfill development to ensure sufficient leachate/contaminated water disposal capacity rather than during the initial years of operation.


25

Vegetation • Weeds and invasive species affecting vegetation at and surrounding the site.

• Fire management procedure (including sufficient water storage, distribution and training).

• Emergency management procedure • Sufficient daily cover • Weed management program • Appropriate capping vegetation to

match surrounding species reduce invasion into threatened ecosystems.

Landfill Gas • LFG migration in the unsaturated zone or through service trenches potentially resulting in asphyxiation (from CO2), death or serious injury from explosion to onsite workers and occupants of site buildings, offsite workers in trenches and pits and onsite and offsite infrastructure.

• Emission of trace component – i.e. H2S in ambient air affecting onsite personnel.

• Fugitive emissions of landfill gas migrating in ambient air and through the unsaturated zone

• 1 m thick compacted clay and HDPE geomembrane which will provide a significant barrier for the prevention of lateral landfill gas migration.

• A complete landfill gas extraction and treatment system is also proposed including horizontal and vertical extraction wells.

• Treatment technologies will be based on LFG generation and flow but will initially comprise high temperature flaring.

• A 2.1 m thick geogrid reinforced soil buttress with sufficient permeability to allow any LFG that has moved laterally to be extracted.

Explain why the buffer distance to residents is acceptable The site has extensive naturally vegetated buffers to reduce impacts on the community. The nearest residence is 480 m to the south east of the fill boundary (20 m short of the recommended buffer for landfills given in the EPA landfill BPEM guidance), but is protected by the natural topography. The current buffers are likely to be maintained with a low potential for future encroachment due to planning restrictions. Further information on separation distances is provided in the Executive Summary Report included with this application.
