1SEAM is an environmental management consultancy with complementary environmental health services which

commenced operation in 2002. SEAM provides a state wide service specialising in environmental impact assessments, and environmental & public health contracting and consulting. SEAM is a business founded on the premises of sustainability. In Tasmania, the principles of sustainable management (development) are enshrined in a suite of legislation known as the Resource Management and Planning System.


Background to the Report

1.1 General

Hagen Oil are Tasmania’s main oil recycler and in order to accommodate the demand for oil

recycling, they urgently need to obtain a larger premises.

Hagen Oil is a trading name of Gourmet Oil (Australia) Pty Ltd - ACN 076 085 884 and is a small

business engaged in the collection and recycling of used oil for reuse.

A Development Application (DA) prepared by ER & Associates for Hagen Oil was submitted to the

Launceston City Council in October 2013 for the relocation of Hagen Oil from the current premises

in 26 Murphy St Invermay to a bigger and new green field yard at 8 Venure Court, Invermay,

Launceston. The Council as the planning authority referred the DA to the Environment Protection

Authority. In January 2014, Environmental Effects Report Guidelines – Gourmet Oil (Australia) Pty

Ltd Oil Recycling Facility were issued. This report is based on these guidelines. The EER report is

provided in support of the planning application. The EPA Board (or Director by delegation) will

provide environmental permit conditions to Council for inclusion in any permit they issue.

Hagen Oil currently operate under the following permits which will be renewed at the new premises

• Controlled Waste Handler Certificate of Registration.

• Tasmanian Fire Service approved plan and

• Safe Work Tasmania compliance.

A Trade Waste Agreement with Tas Water is in progress. Hagen Oil also have an Environmental

Management System in preparation. All equipment and processing activities from the existing plant

will be relocated by Hagen Oil. Hagen Oil will bring in new equipment to the new facility so as to

ensure the operations are conducted efficiently.

Hagen Oil intend to meet contemporary discharge standards for discharge to sewer in accordance

with an agreed Trade Waste Agreement. The intention is to install / implement pre-treatment

equipment and risk control measures required to meet the Trade Waste Acceptance Criteria

Solid waste will be managed at the Launceston Remount Road landfill or other approved facilities.

Odour, and noise emissions are considered to have a negligible impact based on past practices.

All stored oily materials will be in bunded areas and under cover.

PART B – PROPOSAL DESCRIPTION

B.1 Description of proposal

The main aim of this project is for Hagen Oil to relocate to a larger yard and become more efficient in oil recycling and hydro carbon impacted waste water processing. The relocation will allow expansion to meet its clients increasing demands.

All equipment and processing activities from the existing plant will be relocated by Hagen

Oil. Hagen Oil will bring in new equipment to the new facility so as to ensure the operations

are conducted efficiently.

Hagen Oil intend to meet contemporary discharge standards for discharge to sewer in

accordance with an agreed Trade Waste Agreement. Although some detail of pretreatment

is provided (E.g. Floc tank and carbon filter) such detail and specific equipment will be

finalised at the Building Design phase and it is the intention of Hagen Oil to meet a TWA.

Solid waste will continue to be managed at the Launceston Remount Road landfill. Any controlled waste generated from treatment or pre-treatment will be managed as a controlled waste under a Controlled Waste Handler Certificate of Registration and as approved by the EPA

Odour, and noise emissions are considered to have a negligible impact based on past

practices.

All stored oily materials will be in bunded areas and under cover. The new premises will be

a very significant environmental improvement to that of the old yard.

Hagen Oil are and will remain conveniently located being both centrally and geographically close to its main client markets. Being a state wide service industry, the location will ensure that Hagen Oil will continue to serve its wide range of clients in an efficient manner.

Hagen Oil clients include a broad range of different industry sectors including the following :

• viticulture,

• agriculture,

• food production,

• aquaculture,

• dairy, mining,

• manufacturing,

• educational,

• forestry,

• wind farms and

• Hydro industries, and

• Tourism which is also serviced through the recycling of used oils for the West Coast Wilderness Railway.

Therefore Hagen Oil are an important chain in the cycle of “cradle to grave” sustainable waste management for many industries in Tasmania. Hagen Oil will produce approximately 2900 tonnes of recycled oil products per annum.


The plant will operate from 7 am to 5.30 pm for processing of materials. Recevial of materials may occur outside of these hours to handle emergency or urgent collections. Truck movements can occur at these times.

Figure 1 and Plate 1 below shows the new factory layout which shows the covered areas and separate sections of the floor layout for the 3 main areas namely: - Bunded storage area (with holding capacity greater than the amount to be stroed for drum storage, storage of clean oil re resale, tool shed, forklift and drum washing - Tank farm for processing including up to 18 different sized storage and treatment tanks (also bunded)

- Truck entering and off loading / loading area which will be bunded by ramping above the surrounding gravelled area

Any wastewaters generated from these three areas, apart from being a bunded area, will be blind so that watery oils are collected and pumped back into the overall oil/water treatment system and eventually after appropriate pre treatment discharged to sewer. This is discussed further under liquid waste.

Plate 1 – Model of Factory layout


Materials Management

The site will handle materials in different ways almost on a daily basis. For example

material received after settling may be decanted into up to 8 or 9 tanks. This will allow

materials to settle over longer times. Some of the settling processes may take up to several

months to achieve the objective of separation for reuse or management.

Apart from passive treatment of oily and water wastes, Hagen Oil will continue to carry out

drum washing as has occurred at the old Hagen Oil yard for the last 20 years;

Hagen Oil will not collect for processing or treatment wastes [a, b c and d]. If these waste

are received ( E.g. in mixed loads or otherwise by error) they are to be managed as noted

for each material:

a) Any form of PCB or PBB material; Note: if this material arrives it is not held or processed at the yard 2; note PCB being a transformer liquid, if heated becomes carcinogenic therefore Hagen Oil are aware that heating this material is not an option

b) Any solvents in any form

c) Any Organo chlorine pesticides or organo phosphate pesticides; Note: the current activity may have highlighted some traces of these materials and this is most likely due to residuals from Council bulk tank collections 3; with the new premises such oils will need to be tested for the presence of pesticides prior to collection

d) Grease trap waste Note in the future Hagen Oil may look to expanding its operations to take grease trap waste)

Materials and activities that Hagen Oil do and will continue to accept or carry out include:

• Oily water mixtures

• Some materials that may contain ethyl glycol; this material will be collected and stored for sending off site.

2 some low level material that may arrive at the yard is topped up to a 205 L drum and sent to

Sibelco at Mole Creek with documentation as approved by the EPA 3 it is the policy of Hagen Oil to now only receive liquids in triple rinsed used drums so as to avoid

any pesticide residues;


Solid wastes managed at the site will include oil filters, drums, sludges and sediments that

may be within the oily waste and are spade-able; Oil filters are drained of oil for reuse;

Once the liquid waste is processed by settling on site there remains some solid waste such

as oily sediments; these are decanted into a 205 litre drums and covered and when a drum

is full it is sealed and treated as solid waste. Other solid waste will include solids that will

be periodically removed from other tanks and solid wastes generated by the pre-treatment

system. The amount generated is approximately a maximum of 70 kg per week, equating to

one drum every 3 weeks.

These materials are stored on site pending future disposal; it is intended for this legacy

material estimated to be approximately 70 cubic meters to be relocated to the new yard

and stored there, labelled and in a bunded area until a suitable method of disposal is

identified. The processing and management of this legacy material in not part of this

proposal 4 However an inventory of these waste will be maintained and Hagen Oil commit

to completing an investigation of suitable reuse / disposal alternatives within 6 months of

approval.

In the last 5 years, Hagen Oil have washed and sold approximately 7000 drums, sold

approximately 1000 open topped drums, crushed and sold approximately 9000 drums, and

used 500 drums in-house; this equates to 3,500 drums per annum.

Hagen Oil will ensure that it has the appropriate Work Safe Tasmania approvals.

Quantities Processed

Typically in a year, Hagen Oil will process the following quantities of materials:

Material Quantity per annum (kL) Waste Code Bilge water 400 J 120 Pit waste 200 J 120 Industrial wastewater 200-300 Soluble Oils 200 J100 Service washout wastewater 500

Solid Waste = approximately 3500 kgs per annum (approx. 17 drums @ 205L)

4 Investigations are continuing into the most appropriate disposal options including the treatment by

landfarming prior to disposal in a Category C cell in Tasmania, fixation or transport by a contractor for treatment on the mainland (E.g. ToxFree in Victoria) for blending/separation/high temperature incineration


Figure 1 provides a general flow diagram of materials flow proposed at Hagen Oil

Trucks will enter the yard with tankered materials or individual 205 L drums.

Material on arrival is checked against the transmittal papers and logged into the companys

database. A sample of the material is assessed for odour and colour and if there are any

solids present. If the material does not meet Hagen Oil Specifications of its expected load

then the vehicle is send back to the supplier. If material is out of specifications but suitable

for on processing then it will be stored in the main bunded area of the factory and forwarded

onto other processors interstate.

After initial assessment, which may include laboratory analysis, the oil/water mixture is

discharged to a settling tank from which the oil is skimmed off the top and water taken off

near the bottom. Any solid material that settles to the bottom of the tank is treated as solid

waste after any oil is allowed time to drain out.

Oil is sent to a series of oil settling tanks for further refinement and creation of recycled oil.

Any waters generated from the process are sent back to the water treatment line and tanks.

The recycled oil is stored in tanks or drums prior to dispatch as a used product. Hagen Oil

produce approximately 2900 tonnes of recycled oil products per annum.

Any watery material generated from the initial settling tank, and from the oil settling tanks, is

pumped to a series of tanks for further treatment by settling.

Wastewater from the process is treated by settling and decanting and removal of solids.

Final treatment details will be finalised at the BA stage and are likely to involve flocculation

and filtration in a carbon filter if required so that effluent meets Trade Waste Standards to

be set by Tas Water.

As is discussed above waste water and other materials accepted by Hagen Oil are stored

and then settled over time only. No mechanical agitation processes or chemicals are used

to aid the settling. The separation of the water, the oil and the heavy particulate matters

occurs naturally.

B.2 Proposal area

The premises at 8 Venture Court will be undercover and the whole shed will be fully

bunded. This will enable the premises to generate low emissions and therefore low off-site

impacts.

The location is adjacent to the Tea Tree Bend Sewage Treatment Plant run by Tas Water. The proposed lot is adjacent to the Sainty bus depot and other recycling industries. The land is currently owned by others and is zoned as light industrial therefore the proposed use is compatible with the surrounding land use. The land is undeveloped and was once Port of Launceston Authority land and was subject to regular flooding. It has been filled with a range of fill materials so as to be above the local flood levels. The site has been filled to over 1 meter with materials consisting of a mixture of dredged silty / clay material from the Tamar Estuary dredging operations as well as old port gravels. The site will be developed by lot levelling based on the existing surface area shown in Figure 4 and will require minor shooting of present high pints pushed into hollows. The original subdivision planning permit has a condition that any development shall not occur until the site soil and fill materials are assessed. Therefore as part of this assessment, several soil samples were obtained and analysed to ascertain if any of the fill material is contaminated. This is reported elsewhere in this report. Sample locations are shown in Figure 4 The topography is relatively flat with minor undulations and a slight fall towards the east. The site has no vegetation.

B.3 Site Plan

A general location map is shown in Figure 2. As can be seen the premises is in an industrial area of Launceston and nearby to several other industries including Sainty bus depot and the Tea Tree Bend Sewage Treatment Plant. An aerial map of the new site is shown in Figure 3. The former premises was located at 26 Murphys Rd, Invermay (see Figure 3). The old

yard and the new location are very close to each other therefore is discussing the aspects

and environmental impacts of the proposal , consideration has been given to past

operations. Nearby sensitive uses are also marked on Figure 3.

Site plans of the proposed facility are shown in Figures 4, 5 and 6. An access plan and elevations of the new shed are also provided. As can be seen the proposed facility is on land of approximately 4028 m2. This will enable vehicles to access, turn around and egress the factory with convenience and provide ample storage. Storm water locations are shown on the site plan.

B.4 Rationale and Alternatives

When Hagen Oil commenced operations approximately 25 years ago, it was classified as a Level 1 environmentally relevant activity pursuant to the Environmental Management and Pollution Control Act 1994 (EMPCA). However after an amendment to the definition of an oil refinery was made under Schedule 2 (1) (c) of EMPCA to include ‘the conduct of works at which used oil is refined or reprocessed by filtration or physical or chemical separation’, Hagen Oil was constituted an oil refinery and therefore became a Level 2 environmentally relevant activity. For this project, the EPA have deemed the activity as a Level 2A project (refer to the EPA website for details on levels of assessment). Level 2A is the lower end with respect to environmental impacts of Level 2 activities. There is not expected to be any major change in operations at the proposed new site. As the site is significantly larger, and better able to handle the activities involved with oily waste processing, it will not generate any likely increase in emission of pollutants. It, in fact, will reduce any likely emissions. All materials will be stored under cover in a bunded large shed with increased space to store materials avoiding the need to triple stack drums There will also be more space improving access and the processing of materials. Hagen Oil provides a critical service in the processing industry chain, including handling used oils from ships and maritime vessels, used oils from the automotive and hydraulic industries, the mining industry, the forestry industry and any industry that uses mechanical equipment. Approval of a state of the art oil reprocessing industry will enhance future industry investment. The lack of an expanded oil and liquid waste reprocessing facility will continue to hinder Tasmania’s economic expansion. This project is complimentary to the need for a Category C cell for solid waste and without this infrastructure, particular future developments may not occur and the developer may choose to move investment to another state of Australia. Sustainable waste management under pins many new projects and the clean green image of the state is under pinned by such practices. Tasmania needs a state of the art oil and liquid waste processing facility in order to fulfil Tasmania’s stated objective of sustainable waste management (EPA 2009). The proposed location of the facility is conveniently site in the most central major city in

Tasmania, Launceston, and provides for easy access to all sectors of the State.


PART C – potential environmental effects

C.1 Flora and Fauna

This site is unusual in that it contains no vegetation as it is essentially on reclaimed land (see cover

photograph).

C.2 Stormwater Management

Figure 4 details the drainage system for the site. As the new yard is under cover, the

amount of storm water is expected to be low, as compared to the combined sewer /

stormwater outfall at other yards in the Launceston area.

In the uncovered areas of the site, which will consist of compacted gravels, there are proposed to be six separate stormwater collection pits connected by a series of 150mm stormwater pipes. All stormwater pits shall be trafficable grated pits. The final pit will contain a triple inceptor trap that will capture any unexpected storm water discharge. The detailed design of the triple inceptor trap is being undertaken by SEMF consulting engineers. There will be no increase in critical storm peak runoff to the existing storm water drain resulting from site development.

C.3 Significant areas

The Natural Values Atlas (NVA), a database held by the State Government, does not list any significant areas at on near the site. The site is the flood plains of the Tamar River. There are no National Parks, State Reserves, Regional Reserves, Forest Reserves or Conservation Areas within 500m of the site.

C.4 Coastal zone

The site is over 45 kilomters from the coastal zone

C.5 Marine areas

There are no marine reserves nearby


C.6 Air emissions

As the site is a concrete yard and compacted gravelled areas that surround the main shed

there are not expected to be any significant dust emissions. The only odour or air

emissions are from hydrocarbon volatilisation from stored oil. This tends to be a low back

ground oily smell and is understood not to be detected off site apart from the access ramp,

and possibly some build up in drainage pits.

C.7 Liquid effluent

Wastewater emanating from the site can be broadly divided into two categories:

• Floor and yard wash down water , and

• Toilet, wash hand basin and kitchen site sullage

Liquid wastes managed at the site are listed in section B1 and makes up to approximately

1.5 million litres per annum. It includes industrial waste waters such as engine room bilge,

soluble oils and coolants. Hagen Oil also receives some commercial waste water, engine

room bilge and industrial waste water.

General domestic wastewater will be discharge directly to the sewer.

Floor waste will be first pre-treated in a series of two triple inceptor tanks where oily material will be skimmed off and sent back to the treatment plant by a pump and pit for reprocessing within the shed. The shed will contain three sumps that will not be connected to any other parts of the drainage system. These are:

� Bunded tank area sump

� Drained driveway sump

� Drained drum storage sump

The sludge at the bottom of the sumps will be periodically removed and treated as a solid,

spade-able waste and solidified. The clearer water will then be discharged to sewer after

a series of tank settling processes and flocculation in a Floc tank. There will be the option of

using a Carbon filter to further improve the quality of the effluent so as to meet Trade waste

Standards as set by Tas Water. Prior to any such pre-treatment being installed, there will

be a commissioning period to determine what level of pre-treatment is necessary. Any solid

wastes generated from pre-treatment will be managed separately as a controlled waste

(See section C 8)

Industrial waste waters include engine room bilge, soluble oils and coolants as products

from the oil recycling process which are on sold as products.

The remainder of the yard, consisting of hard pan compacted gravel surface, is not subject

to any oil storage, and will have stormwater discharged direct to the storm water system.

However as a precaution, there will be a triple inceptor trap at the last pit to treat

stormwater before it leaves the site (see section C2 – Stormwater management)


All stored oily materials will be contained in a bunded area and located under cover. The

arrangement will be a significant environmental improvement on the past site facility that

has been reiterated in correspondence from Tas Water (see Appendix C).

The draft Trade Waste Agreement (TWA) emission standards issued by Tas Water have

been issued and Hagen Oil are currently in discussion with Tas Water to finalise a TWA.

The proponent is seeking a Trade Waste Agreement to allow an average discharge to

sewer of approximately 40,000 L/day with a maximum of not more than 100,000 L/day so

as to allow for daily volumes to vary and to allow for contingencies.

Since this application process commenced, Tas Water, have become more active in

seeking a TWA and have issued draft Trade Waste standards. Consequently Hagen Oil

will need to manage client’s inputs to ensure material entering the waste stream and

leaving the site are compliant.

Environmental Commitment: Hagen Oil is committed to ensure it meets its obligations to discharge an

acceptable waste stream to the sewer and has the intention to implement appropriate pre-treatment

equipment and risk control measures to meet a TWA

C.8 Solid Wastes

Hagen Oil normally generate approximately 50 tonnes per year of solid waste which will be

sent to the Launceston City Councils Remount Road Landfill.

These waste materials consisted of loose mixed waste and assigned to various waste

categories by the LCC including:

Commercial and Industrial Waste groups - C&I -1, C&I -3, C&I -4 and C&I -5

Construction and Demolition Waste groups C&D -2, C&D -4 and C&D -5

Waste will be stored in Tox Free / Jones's skip bins under the roof of the new yard and any skip bins not under cover will be lidded. Any controlled waste generated from treatment or pre-treatment will be managed as a controlled waste under a Controlled Waste Handler Certificate of Registration and as approved by the EPA Environmental Commitment : All solid waste will be stored in waste bins with lids and removed

when full to an approved waste depot; Any controlled waste as defined in the Environmental

Management and Pollution Control (Waste Management) Regulations 2010 will be managed only

with a Controlled Waste Handler Certificate of Registration

Hagen Oil commit to maintaining an inventory of any legacy materials and complete an investigation

of suitable reuse / disposal alternatives within 6 months of approval.

Hagen Oil also commit to providing storage of any material that cannot be processed on site in a

fully bunded area and appropriately labelled.


C.9 Noise Emissions

The site is located adjacent to similar light industries either side including Veolia

Environmental Services, a waste transfer station and the Tea Tree Bend Sewage

Treatment Plant resulting in some relatively consistent background noise .

The operations of Hagen Oil are not a noisy business with the most potential noise being

that of truck coming and going from the yard. There is expected to be approximately 20

truck movements per day. Any pump noise is very low as most of the pumps are in tanks.

The proposed yard will be constructed so as to enable vehicles to drive through and avoid

reversing which can be a noisy operation.

Given the consistent background noise of the sewage treatment plant and similar industrial

operations together with the open and spacious development site, there is not expected to

be any noise issues of concern.

Environmental Commitment – If noise complaints are received and verified then Hagen Oil commits

to conduct an environmental noise survey to ascertain impacts on sensitive receptors.

C.10 Transport Impacts

The proposal involved approximately 20 truck movements per day. It is not expected to lead to any increase in truck movements along Murphys St during business operations. The construction phase will result in a short term slight increase in traffic movements.

C.11 Other off site impacts

The adjacent sewage treatment plant is likely to lead to odours entering the site.

Figure 7 below shows the nearest houses to the proposed activity. There are no schools of

other sensitive uses nearby and the nearest house is 65 m to the south west.

Figure 7 – Location of nearest sensitive uses


C.12 Hazardous Substances

The terms hazardous waste, prescribed waste and controlled waste are used by various

Australian environment protection agencies and to all intents and purposes are

interchangeable. Tasmania has adopted the terminology of the National Environment

Protection (Movement of Controlled Waste between States and Territories) Measure 2004

which uses the term controlled waste.

Controlled waste includes those wastes that exhibit toxicity, chemical or biological reactivity,

environmental persistence, or the ability to bio-accumulate or enter the food chain. These

wastes may be produced in a gaseous, liquid or solid state. It is environmentally

unacceptable to dispose of controlled waste by the same means as we dispose of the more

common by-products of our everyday lives.

Control wastes are listed in the regulations and the handling of them requires the approval

of the Director of Environmental Management. Gourmet Oil (Australia) Pty Ltd hold a

current Controlled Waste Handler Certificate of Registration.

Hagen Oil are already approved to handle the following controlled waste:

Waste Code Waste Category B100 Acidic solutions or acids in solid form C100 Basic solutions or bases in solid form F100 Waste from the production, formation and use of inks, dyes, pigments,

paints, lacquers and varnish

F110 Waste from the production, formation and use of resins, latex, plasticisers, glues and adhesives

J100 Waste mineral oils unfit for their original intended use J120 Waste oil/water, hydrocarbons/water mixtures or emulsions N100 Containers which are contaminated with residues of substances referred to

in this list * N120 Soil contaminated with controlled waste N160 Encapsulated, chemically-fixed, solidified or polymerised wastes referred to

in this list *

N190 Filter cake contaminated with residues of substances referred to in this list *

*“in this list” means in Schedule A – List 1: Waste Categories, of the National

Environment Protection (Movement of Controlled Wase Between States and Territories)

Measure

Aside from controlled waste, Hagen Oil are also subject to the Dangerous Goods

provisions. However Hagen Oil are exempt from a Dangerous Good licence because the

flammable liquids it manages do not give off flammable vapour at temperatures of not

greater than 60.5 Celsius closed cup test of not more than 60.5 Celsius open-cup test.

Environmental Commitment – Hagen Oil will comply with the management of controlled waste

through a Controlled Waste Handler Certificate of Registration


C.13 Site contamination – historical

The site is understood to have been filled with a range of materials so as to be above the

local flood levels. The fill is well over 1 meter deep with materials consisting of a mixture of

dredged silty / clay material from the Tamar Estuary dredging operations as well as old port

gravels.

Consequently, a series of sediment samples were taken and analysed by the most likely

contaminant, chemical of potential concern, that being heavy metals. Figure 3 above

shows the 3 sampling locations which are:

S1 – Clay type will at approximately 100mm depth

S2 – Natural ground below the fill at approximately 2m in a pit excavated by Tas Water

S3 – Gravel / soil fill at approximately 100mm depth

The results of the heavy metal analysis are provided in Appendix C. If it is assumed that

the natural background levels of heavy metals are those in sample S2, then the following

can be gleaned from the soil sampling program:

• The background levels of Al, As, S, Zn K B and Cd are all higher than the fill material

imported

• The background levels of Fe, Mg, Ca and Na are all lower than the fill material

imported

• The soils on site vary in consistency and heavy metal concentrations however given

the site is mainly clay materials there is unlikely to be any migration of heavy metals

off site

C.14 Climate change

The actual business of recycling oil is inherently a greenhouse house gas and climate

change positive industry

The largest impact however from the operations are the use of trucks to collect the

materials. Hagen Oil has a modern fleet of truck which mostly use low sulphur diesel fuels

and have the capacity of using bio diesel.

C.15 Heritage

The site is not on or near any places on the Tasmanian Heritage register

An assessment of Aboriginal heritage was carried out and the response to the search is

provided in Appendix D.


C.16 Site of high public interest

The site of most public interest to the development is the Tamar River.

C.17 Rehabilitation

It is intended that in the advent of the operations being terminated, the site will be

decommissioned and remediated. The proposed shed will be dismantled and removed as

will the proposed office and amenities building. Concrete slabs will remain on site for future

use.

Environmental commitment – Hagen Oil will prepare and implement a closure and rehabilitation

plant within 6 months of vacating the site.


PART D - Management Commitments Hagen Oil provides a critical step in the cycle of hydrocarbon management. They manage a range

of waste materials such as oily water, used oil, oil filters, sludge containing oily products and other

hydrocarbon derivatives.

Hagen Oil products include recycled oil for use as a fuel or lubricant.

The new premises will provide contemporary oil recycling premises that will serve Tasmanian industries and waste oil generators

Throughout section C of this report there are a number of environmental commitments listed.

These, together with associated issues identified in conducting the environmental impact

assessment, are collated in the Table below:

obligations to discharge an acceptable waste

stream to the sewer and has the intention to

implement appropriate pre-treatment

equipment and risk control measures to meet

a TWA

5 Solid Waste Management

Capture and containment of solid waste

All solid waste will be stored in waste bins

with lids and removed when full to an

approved waste depot.

Hagen Oil also commit to providing

storage of any material that cannot be

processed on site in a fully bunded area

and appropriately labelled

6 Solid Waste Management

Management of legacy waste

11 Fire Emissions of noxious odours

Develop and seek approval for a Fire

Management Plan prior to commencement

Immediately contact the Tasmanian Fire

Service and activate the Fire Management

Plan


Part E – Public consultation

Once the EPA and the LCC have sufficient information, there is a formal period of advertising in

which interested parties may lodge representations about the proposal. This is expected to be a 2

week period and it is at this time that the formal public consultation will take place.

The following consultation has taken place to date:

• Discussions and site visit with the current site owner

• Discussions with existing site operators of other blocks of land within the industrial

subdivision

• Preparation of a 3D model (suitable for display if desirable during the consultation period)

Consultation with Government has included:

• An on site meeting between officers of the LCC, EPA, Tas Water and Hagen Oil was held in

November 2013

• Communication and discussion with DHHS representative

• Meetings and discussions with EPA officers

Mr Doug Hagen

Dear Mr Hagen

Proposed Relocation of Hagen Oil Pty Ltd

I write to you to express my support of your proposal to relocate your business, Hagen Oils from 26 Murphy

Street, Invermay to an alternative location better suited to conducting your expanded business operations.

As per our recent discussions I have concerns regarding the risk of your current operations and location, in

particular the discharge of trade waste into sewer. This concern is intensified by the fact that your business

is currently located in an area serviced by a combined sewerage system increasing potential for accidental

spills of stored products to enter the sewer.

During our discussions you have indicated that relocating your business will allow you to address the

following restrictions of your current site:

• Material currently stored in open areas will be able to be stored under cover in a securely bunded

area to protect against spills;

• Current pre-treatment will be upgraded as necessary to meet TasWater sewer acceptance limits;

• Larger footprint will allow you to more appropriately segregate different waste products to ensure

sufficient risk controls are in place.

I view your proposed relocation as an ideal opportunity for TasWater to assist you in ensuring all relevant

legislation and regulatory requirements are understood and attended to as part of the process.

I look forward to assisting you should you receive the relevant approvals to develop your business at an

alternative location. If you have any further enquiries or require additional information from TasWater

during this process please contact Mr David Holman on 6237 8285.

Yours sincerely

Travis Richards

State Manager – Trade Waste

RE: ABORIGINAL HERITAGE DESKTOP ASSESSMENT

HAGEN OIL RELOCATION TO VENTURA DRIVE INVERMAY

Aboriginal Heritage Tasmania (AHT) has completed a search of the Tasmanian Aboriginal Site

Index (TASI) regarding the proposed relocation of Hagen Oil to 8 Ventura Drive, Invermay and can

advise that there are no Aboriginal heritage sites recorded within or close to the property. Due to a

review of previous reports it is believed that the area has a low probability of Aboriginal heritage

being present.

Accordingly there is no requirement for an Aboriginal heritage investigation and AHT have no

objection to the project proceeding.

Please be aware that all Aboriginal heritage is protected under the Aboriginal Relics Act 1975. If at

any time during works you suspect Aboriginal heritage, cease works immediately and contact AHT

for advice. Attached is an Unanticipated Discovery Plan, which you should have on hand during

ground disturbing works, to aid you in meeting your requirements under the Act should Aboriginal

Heritage be uncovered.

If you have any queries please do not hesitate to contact AHT.

Kind Regards,
