existing developments. An aspect of the work is to strive for sustainable management of our resources.


SUMMARY

This Environmental Effects Report (EER) has been prepared to provide supporting

information to the Board of the Environment Protection Authority under Section 27 of the Environmental Management and Pollution Control Act 1994. The Huon Valley

Council have advised that the current approved use of the site is Light Industry and

that no planning approval would be required for the proposed increase in production

to 3000 tonnes per annum, subject to the operating hours remaining at 7am to 7pm

Monday to Saturday.

The following parameters form the basis of the development:

a maximum of approximately 3,000 tonnes per annum of fish will be processed;

and

products will mainly consist of marine farmed salmon, and other fish products on

a much smaller scale (E.g. shell fish, trawl fish and fish harvested on a seasonal

basis. Salmon from Macquarie Harbour will not be processed at this facility.

The key environmental management issues and recommended measures to mitigate

impacts are listed:

1. The operations will continue to focus on dry, clean up of any fish waste and

diligent attention to management of floor drains to minimise any solids to the

sewer.

2. Wastewater will be disposed of to the existing sewage connection within the

premises. Discharge levels will not exceed any trade waste agreement.

3. Solid fish waste will be taken off site by Veolia to the existing fish meal plant at

Triabunna. Solid fish waste will be stored in marked crates in a coolroom and

held for not greater than 48 hours.

4. Odour management is linked to attention to good house keeping. Good

housekeeping will continue to be a feature of the fish processing operations by

Huon Valley Seafoods.

5. Noise management will be managed in accordance with recommendations of a

specialist noise report prepared for the site.

FOREWORD

Huon Valley Seafoods (HVS) has operated since September 2000 as a major processor of

Atlantic Salmon for both Spring Smoked Seafoods and Huon Aquaculture at their Port Huon

site.

In May 2008 the premises at Port Huon was sold to Huon Aquaculture and Huon Valley

Seafoods moved to the current premises at 49 Wilmot Rd Huonville. The premises was originally set up as a fruit processing plant and then in 1995 it was taken over by Osprey

Seafoods Pty Ltd for processing abalone.

Additional to this HVS has been a major supplier of other services to industry within the

Huon area including cold storage, blast freezing and ice production. The company has been

handling and freezing apples, fish heads and frames for pet food, apple juice and Atlantic

Salmon.

Following the sale of the Port Huon site most of these services have been carried out at the

current HVS site at 49 Wilmot Road, Huonville, which has included handling up to 3000 tonnes of product annually. This has all been under the above services of freezing, handling

and storage.

Loss of HVS customers has meant a reduction in work at the site. Therefore HVS is now looking to cover this loss by the expansion of the processing side from the current Level 1 of

100 tonnes of processing to approximately 3000 tonnes per annum. This requires HVS to

move to a Level 2A or 2B permit under the Environmental Management & Pollution Control Act 1994. The class of assessment as to 2A or 2B has to be determined by the Director of the

EPA.

PART B - PROJECT DESCRIPTION

1. Description of Project

An EER is required as Huon Valley Seafoods (HVS) intend to extend their operations

from freezing and packing of fish and a small amount of processing of fish to contract

processing of salmon and other fish products to a maximum of approximately 3,000

tonnes per annum of fish. The EER aims to provide assessment and management of

any potential environmental impacts as a result of the addition of contract processing

of fish at the factory.

The following form the basis of the application:

the amount to be processed is approximately 3,000 tonnes per annum, and

products will consist mostly of marine farmed salmon, shellfish, trawl fish and

other fish harvested on a seasonal basis.

The property is situated at 49 Wilmot Road Huonville (see Figure 1). The area is

Light Industrial with several other businesses surrounding the premises as well as

several dwellings located at the front of the premises on Wilmot Rd.

A Location Plan is shown in Figure 2.

The existing factory layout which will not change in the short term as shown in

Figure 3. It is noted that a proposed freezer extension has already been approved by

the Huon Valley Council and this project will proceed in the next financial year.

The steps in the processing of fish and fish products are outlined in Figure 4. Fish

will be delivered to the factory by truck and unloaded to cool storage by a forklift.

Fish will usually arrive in sufficient time for processing so as to be ready for delivery

to market by the next morning. The business will continue to operate between 7am

and 7 pm Monday to Saturday

The fish will be processed in modern stainless steel equipment and stored on ice for

transport to market. The fish to be processed will be mainly Atlantic Salmon from

local fish farms. There will be no processing of fish from Macquarie Harbour. Fish

will be placed in a blast freezer or one of several coolrooms and be loaded into trucks

and transported to market.

The site infrastructure will include existing factory facilities and an approved but yet

to be constructed cool store on the south-west site boundary. The new cool store will

also reduce any operational noise (See later section of Noise Management).

PART C - POTENTIAL ENVIRONMENTAL

EFFECTS

This section describes how the operations are to be managed and operated so as to meet

satisfactory environmental performance standards. It is a statement of proposed service and

potential environmental impacts in the context of adding contract processing of fish to the existing fish storage and handling operations. The development does not require a

Development Application under the Land Use Planning and Approval Act 1993 as determined

by the Huon Valley Council (Appendix C). However as the amount of fish to be processed

will reach level of greater than 100 tonnes of products, an assessment is required by the Board of the Environment Protection Authority (EPA). It is anticipated that the EPA will issue an

environmental protection notice based on this EER for ongoing environmental regulation.

Huon Valley Seafoods Pty. Ltd. is committed to meeting and exceeding all contemporary

environmental standards. It meets its environmental duty and seeks to obtain a Level 2

approval under the Environmental Management and Pollution Control Act 1994 for the operations.

The EER is structured by listing the potential environmental impacts for each aspect, and then

evaluating the impacts and providing measures to mitigate any significant impacts.

1. Flora and Fauna The factory is located behind residential dwellings in Wilmot Road, Huonville and the

facilities cover the entire site, with no remaining vegetation apart from a small strip of lawn along the northern boundary. It is intended to landscape the northern perimeter of the site

with trees. The eastern permitter is already landscaped with a hedge and the southern

permitter boarder other Light Industrial activities (Red Shed Restorations and Total Auto Mechanics). The western permitter extends across open pasture to the Huon River some

250m away.

2. Rivers, creeks, wetlands & estuaries The site is 250m east of the Huon River. Stormwater is collected in the Council stormwater

management system and is discharged to the Huon River.

3. Significant Areas There are no significant reserves within 1 km of the factory. There are sports grounds on the other side of Wilmot Street and the Huonville High School is over 500m to the north also on

the eastern side of Wilmot Rd.

4. Coastal Zone The site is located 250 metres east of the Huon River. It has no coastal impacts.


5. Marine Areas The site is not located in or near any Marine Areas.

6. Air Emissions (includes odour)

Air Emissions Potential Environmental Impacts The major sources of air emissions are:

odours from existing waste in contracted waste transport vehicles

fugitive odours from the fish on receival odours from the solid waste skip bins when being loaded to trucks

any rotten or putrid fish from the processing chain that may emanate from the factory

Factory Emissions Impact Evaluation The premises are positioned to minimise odours as it is surrounded by open space on all sides.

A car park is located at the factory front and provides a buffer zone to yards of three dwellings located on Wilmot Road. A large hedge screens the factory from these dwellings

The most effective way to minimise any odours is to ensure that fish waste is stored in the

coolroom and taken off site as soon as is practicable after processing operations. This measure ensures efficient processing operations and is a sound management practice. The

premises are run on mains electricity so there are no other air emissions.

Air Emissions Mitigation Measures Air emissions are to comply with the relevant provisions of the Environment Protection

Policy (Air Quality)3. The relevant section in the Schedule states that if the regulatory

authority is satisfied that an odour from an activity is likely to cause environmental harm or

an environmental nuisance, the authority should require that the odour emission from the

source not exceed the odour criteria specified in Schedule 3 at or beyond the boundary of the land on which the source is located. Schedule 3 of the policy states that odour emissions

should not exceed 2 odour units for one hour at modelled 99.9% ile concentration. This level

is unlikely to cause complaints from people with normal odour sensitivity.

HVS aims to ensure that nuisance odours will not be detected to any significant degree

beyond the boundary of the premises as determined by odour modelling. HVS will operate a

detection system for nuisance odours which includes checking for fugitive sources regularly.

Greenhouse Gases With respect to green house gas emissions, there is no prior measurement of greenhouse gas

emissions for the operations. The operations have relied on main electricity as well as slow

combustion engine or diesel vehicles and refrigerant units. There are a total of four refrigerant units as follows:

1 blast freezer

1 holding freezer

3 The Environment Protection Policy (Air Quality) 2004.


2 small chillers

The refrigerant units use the following refrigerant gases.

Refrigerant Gases

404A / 507 a mixture of gases including tetrafluoroethane

Table 3 - Refrigerant Gases

Gas 404A is a relatively new refrigerant gas and it does not contain any ozone depleting substances. The usage will be R404A / 507. Therefore the emission of greenhouse gases is

considered to be negligible.

The units will be serviced by Kibbey and Cooper Refrigeration Pty Ltd

Another coolroom is proposed to be installed in the north west corner of the property. It is

also proposed to landscape the property boundaries so as to provide a visual and amenity

improvement to the premises.

7. Wastewater Management

Wastewater Potential Environmental Impacts The most significant potential environmental impact is if fish processing wastewater were to

seep into the stormwater system. However this is extremely unlikely as all drains in the factory drain to the sewer system.

Wastewater Impacts Evaluation Figure 5 shows the floor drainage system for the collection of wastewater at the factory. The

wastewater collection system for the facility has been designed based on state of the art fish

processing plants as originally set by for abalone processing. Essentially the system of management by HVS is based on a waste minimization approach where floor waste is

collected by a dry clean up with broom prior to any hosing down of the floors. In the factory

there are drainage catchpoints as shown in Figure 5.

The drains have a double stainless steel mesh with openings of approximately 5 mm.

Following this initial floor waste dry clean up, the floors are thoroughly cleaned by hosing, as

the factory has an existing concrete floor and drainage system. All floor waste drains to an existing septic tank estimated to be 2700 Litres. The tank is accessible and amenities waste

discharge into the system below the tank.

The existing 2700-litre tank has been installed to allow for the processing of bulky fish and if

there is a need to hold the solids. Solids will be removed as required. The wastewater drains

to Southern Water’s sewage system at Ranelagh. A permit to discharge trade waste to sewer will be obtained from Southern Water. The maximum amount of anticipated to be discharged

to sewer is 7.8 kL / day however processing will usually only occur 3 days per week and the

existing 2700-litre tank will buffer loads to the system.


Fish wastewater from the proposed contract processing conducted monitoring of its

wastewater stream in 2009 as recommended and advised by Southern Water. Results are listed in the table below with an average for each parameters provided as well as the

Standards for Acceptance of Liquid Trade Waste to Sewer obtained from the Tasmanian

Plumbing Regulations. Those results that are above the recommended standard are shown as shaded.

Laboratory results of samples are attached at the end of this report.

Table 4 - Results of Monitoring of Contract Fish processing Wastewater

It is apparent from the results that 2 parametres exceed the Plumbing Regulations for the

Biological Oxygen Demand and the Chemical Oxygen Demand. Obviously the wastewater from the fish processing operations will contain relatively high BOD due to some blood

entering the wastewater stream. It is proposed however that the contract processing of fish

will be managed by separating out congealed blood and conduct dry clean ups prior to hosing

down the premises. Wastewater will also be held in septic tanks so that the quantities of wastewater are managed.

Wastewater Mitigation Measures It is proposed that all solid matter shall be removed from the floors by sweeping prior to the

floors being thoroughly hosed into the drainage system.

The discharge of solid matter and pollutants in liquid waste shall be prevented by all practical

means including:

good housekeeping, provision of adequate containers to avoid loss to the floor the control of spillages by sweeping, brooming, shovelling, vacuum cleaning,

impoundment


pumping out of sludgy wastes from the separation tank if necessary (capacity 2700 litres) which is on the sewer line

separating out congealed blood and conduct dry clean ups prior to hosing down the

premises

installation of further steel mesh in drainage points

To achieve this end HVS will have comprehensive operating instructions and thorough

training and supervision of employees and contractors on site. Cleaning schedules will be conducted in accordance with the Hygiene Cleaning program outlined below.

HVS has applied for a Trade Waste Agreement to Southern Water.

Stormwater will discharge to the Council storm water system which drains to the Huon River.

All process water will be chlorinated and readings taken once daily by the Production Manager. The readings will be recorded on the Daily Hygiene Report. A residual chlorine

level will be maintained.


Figure 5 - Drainage Plan: Wastewater and Stormwater


HYGIENE CLEANING PROGRAM

The Food Processing Accreditation Manual of HVS details the Hygiene Cleaning program as

follows: EQUIPMENT, TABLES AND APRONS

Hosed down and scrubbed with chlorofoam after each production day and rinsed thoroughly

with a high-pressure hose. FLOORS AND DRAINS

Cleaned daily after production, with a high-pressure hose and Hypochlorite. Steam cleaned at

end of each production run. WALLS

Cleaned daily, with high-pressure hose after production.

Scrubbed with cholrofoam and rinsed thoroughly with high-pressure hose when soiled.

Steam cleaned at the end of each production run. CEILINGS AND LIGHTS

Scrubbed and cleaned with chlorofoam when soiled.

LUNCHROOM, TOILETS AND AMENITIES

Cleaned daily, after production with chlorofoam.

Soap dispensers and paper towel dispensers checked daily.

EDIBLE PRODUCT CONTAINERS AND BINS

Rinsed, scrubbed with chlorofoam and rinsed thoroughly with high-pressure hose after each

production day.

INEDIBLE PRODUCT CONTAINERS (Black)

Rinsed, scrubbed with chlorofoam and rinsed thoroughly with high pressure hose daily after

each production day.

CHILLER

Scrubbed and cleaned with high-pressure hose and chlorofoam when empty, at least once per

week. Cleaned daily, with high-pressure water in vacant areas.

TRANSPORT BINS

Cleaned with high-pressure water, immediately after emptying.

Scrubbed when Soiled.

EXTERIOR

Concrete hosed with high-pressure water immediately after receival of product and at the end

of each production day. Exterior grounds and building maintained on a regular basis as

required.


8. Solid Waste Management

Solid Waste Potential Environmental Impacts Solid wastes are generated throughout the process of fish manufacturing at the following sources:

fish heads, and gut from the filleting line

fish skins from the skinning line putrid or rotten fish

miscellaneous packaging, domestic and commercial waste

Discharge of solid matter and pollutants in liquid waste is and will continue to be prevented

by all practical means with:

good housekeeping

provision of adequate containers to avoid loss to the floor the control of spillages by sweeping, brooming, shovelling, vacuum cleaning

impoundment and pumping out of sludges and solid wastes and collected in a separation

tank (capacity 2700 litres) which is on site.

Solid Waste Impacts Evaluation All solid wastes are to be stored in separate trays and deposited to a skip bin for daily

removal.

All solid wastes handled within the premises shall be contained as far as practicable to

prevent spillage. All wastes stored at the premises shall be held in a leak proof container,

which shall be fitted with a weather proof and animal resistant cover. The cover shall be used

at all times when waste is held in the container. These containers will be clearly marked “waste product only”.

All solid waste will be removed from the premises only by contractors with a current Waste Transport Business Environment Protection Notice licence. It is proposed that Veolia or

another licensed waste transport business continue to take solid waste, as is currently done.

Solid Waste Mitigation Measures All solid waste will be removed to a refuse disposal site or rendering plant licensed and

approved in accordance with the EMPCA. All solid waste is intended to be removed from premises within 48 hours or as soon as is practicable after. It is proposed that Veolia take

solid waste to the Triabunna fish meal plant for processing and it is hoped that in the future

fish gut will also be reused. A contingency is for fish gut to be blast frozen and exported to Asia or failing this sent to George Town Seafoods for making to silage.


9. Noise

Noise Potential Environmental Impacts The main source of noise from the proposed fish processing plant is the refrigeration units used to run the cool rooms. Figure 6 below shows the location of a blast freezer refrigerant

unit (NW of Factory) and three other refrigerant units (SW of factory).

Transport noise is generated from pan techs and other heavy vehicles associated with general industrial activities. Wilmot Road is a major arterial road for traffic travelling to Ranelagh.

Transport impacts are discussed in the next section on Traffic Movements.

The surrounding areas are not tranquil and have noise levels commensurate with a light

industrial area (Ambient back noise levels are at 49d (B)A).

Noise Impact Evaluation Noise emissions from the existing premises have not been a significant issue apart from a

complaint from a resident to the west of the premises in 2009. This noise has been subject to an investigation and report by Pearu Terts Noise Consultant (See Appendix B). Noise

monitoring was conducted on 2/3/09 and 12/5/09. The report was commissioned to identify

the source of any noise and as a consequence works were undertaken to reduce noise levels. It is reported that the house in question is double brick with ceiling insulation and the

windows appear to be the main noise conduit. The blast freezer operates for 24 hours stints

post harvest for various clients at different times of the year and was identified as the source

of the noise.

The property is located approximately 200m away and is by no means the closest neighbour

(there are three dwellings on the eastern side of the factory that front Wilmot Rd). There is also a Furniture Restorer, known as the Red Shed, located adjacent to the factory on the SW

of the site and an auto repairer next to it on Wilmot Rd adjacent to the driveway into HVS.

In summary this is a light industrial area with a commensurate ambient background noise levels and the proposed processing is not expected to lead to an increase in noise levels. The

statistical noise analysis indicated that the area is not tranquil. Rural areas are not usually

tranquil because of farming and associated activities. Wilmot Rd carries traffic including log trucks early in the morning can be heard with an average maximum noise level of 48 dB(A).

The night time noise of the plant according to Mr Terts is likely to be heard at 9 dB(A) less

that is 39 dB(A).

It was reported that the noise level is likely to be acceptable although marginally, because of

the presence of the tonal component which makes low level noises annoying.

The owner of the dwelling that was the subject to the noise complaint to the west has a

proposed subdivision before Council proposed on the south eastern side see Figure 6. Huon

Valley Seafoods has no objection to this subdivision provided that their rights to continue to operate their business is not jeopardised.


Noise Mitigation Measures This issue is being addressed by HVS through the adoption of the recommendations of the

independent noise report. Some enclosures and dampening treatment has been undertaken on

the plant. HVS have also positioned some containers along the south west corner to mitigate the noise impacts. The results of these noise abatement measures has resulted in an ambient

operational noise level L90 = 56d(B)A (11am) and ambient operational noise level L90 =

47.5d(B)A (9.40pm).

The report provides further recommendation as listed below:

The acoustic integrity of the compressor room can be improved;

The plant could be made to be vibration isolated from the enclosing roof and walls

Provide an “acoustic boot” for the small square hole near the door and the an acoustic

noise barrier be installed around the roof mounted fan (i.e. an acoustically lined inner skin of perforated metal with sound absorbing material about 1.5m high)

Consider installing intelligent Reversing Beeper to any vehicles operating on site

(E.g. forklift trucks)

Instigate the practice of sliding material off trucks rather than dropping the material

onto the ground

HVS intend to adopt these practices in a staged approach. It is also proposed to install a

permanent coolroom in the south west corner (see Figures 3 and 6) as a further mitigation

measure. A program of screen plantings of native vegetation is also proposed for the site.

Of note is that HVS have excellent relations with the neighbouring houses and are in regular

communication about their operations. HVS understand any potential noise issues and have been willing to take steps to abate any noise concerns.

Figure 6 – Location of Development with potential Noise Generation points and nearest Noise

Receptors


10. Transport Impacts The traffic movements to the factory have been ongoing since the plant was established over

10 years ago. Recent traffic movements over the last year as reported by HVS were:

Apple deliveries In - February to August three trucks per day into the factory 3 times

per day for 3 day as per week (subtotal = 252 movements)

Apple deliveries Out - February to August two 20 tonne trucks per month (subtotal =

14)

Fish Head and Frame deliveries In – one truck in per day and 2 trucks out per month

(subtotal = 240 + 24 = 264)

Frozen Fish Deliveries – November – April one truck in per day for 6 days per week

and one truck out per day 4 days week (subtotal = 240)

Total Truck movements with existing operations = 870 per annum

With the change to contract fish processing the following transport movements are

anticipated:

Frozen Fish Deliveries – November – April one truck in per day for 6 days per week

and one truck out per day 4 days week (subtotal = 240)

Contract Fish processing – 3 trucks in per week and 3 trucks out per week ( subtotal =

300

Total Truck movements with proposed operations = 540 per annum

Also contract fish processing will lead to more staff movements in their own cars

however the noise impact is not considered to be of the same level as truck noise impacts.

Fort lift trucks will continue to operate with loading and unloading.

Assumptions include breaks on Public Holidays and no processing on Sundays,

operations remain between 7 am and 7 pm

It therefore can be concluded that the transport movements for HVS will in act decrease

to 60% of current traffic movement with the proposed change to the addition on contract

fish processing.

11. Other off Site Impacts There are not considered to be any other impacts apart from those listed herein. The nearest dwellings are located at the front of the premises on Wilmot Road.


12. Dangerous Goods and Chemicals

Hazardous Waste Potential Environmental Impacts Chemical Storage

The chemicals proposed to be stored on site include ezychlor (Sodium Hypochlorite) for

sterilizing the premises. It will be stored separately and handled under strict supervision of the Quality Control Officer. The quantity to be stored is five containers each of 25 litres.

Other chemicals used include:

Alcafoam CL (Foaming chlorinated detergent / sanitiser

Pur – hand 321B (Liquid hand cleaner) Pur-Chlor 127B (Bleach and Steriliser) installed in line

Sewer – Cide (Sewer Cleansing concentrate)

Refrigerant gases including a mixture of gases such as tetrafluoroethane

All chemicals are suitably labelled with warning of toxicity, and directions for use in the

premises. Generators will operate the coolrooms and there is some storage of petrochemical

oils for maintenance. MSD sheets are all held on site.

Hazardous Waste Impact Evaluation There will be very small quantities of hazardous wastes and there are considered to be very

minor environmental issue for this activity.

Hazardous Waste Mitigation Measures All chemicals are suitably labelled with warning of toxicity, and directions for use in the

premises. None of the hazardous materials stored on site requires a Dangerous Goods

Licence. Generators operate the coolrooms and there is some storage of petrochemical oils for

maintenance.

All chemicals, pesticides and poisons will be stored separately and handled under strict

supervision of QC Officer/Manager. All chemicals are to be suitably labelled with warnings of toxicity, and directions for use in premises.

The Manager is responsible for all cleaning programs and trains new personnel on correct cleaning procedures before commencing work.

Any bunding requirements shall be in accordance with the Dangerous Goods Regulations

1998 (Part 7, Section 44), AS 1940 (1993) and AS 3780 (1994). No Dangerous Goods licences are required. As a minimum, all bunding should be impervious to the materials

stored in the bunds and be able to contain at least 110% of the volume of the largest vessel

stored in the bund.

If there is a release of any hazardous material then the Manager will advise both the EPA

Director of Environmental Management and the Huon Valley Council. Containment and

bunding in accordance with the Material Safety Data Sheets will be followed so as to prevent any adverse impacts to the community surrounding the plant.


13. Site Contamination Before being taken over by HVS, the site was used as an abalone canning (retort processing factory) and at one time a fruit processing factory. A full site history has not been undertaken

and the history of pesticide or other chemical storage is unknown. Therefore the site status

should reflect this history and prior to any future change of use to more sensitive use such as residential sue, a detailed site history should be undertaken. However the current and

proposed use will remain as light industrial therefore site contamination investigation is not

considered to be a necessary step with this development.

14. Cultural & Aboriginal Heritage The site has no known cultural or Aboriginal heritage values and the land is not listed on the

any heritage register.

15. Sites of High Public Interest There are no known sites of any high public interest. The premises are located in a light

industrial zone.

16. Rehabilitation The plant and equipment at the premises are all of standard operational condition. The

processing facilities are all stainless steel and there is an existing drainage system for an

existing factory. If the premises close, all portable equipment will be removed and the

premises vacated.

17. Council Information Requirements The premises are in the Huon Valley Light Industrial Zone and connected to both a reticulated sewer system and a reticulated water and storm water system (see Part 7 liquid effluent for

details). It is proposed to employ up to 30 staff. The premises will operate up to 6 days per

week between 7 am and 7 pm. .

18. External Risks HVS has an Emergency Plan for its Huonville premises. The table below lists the likely

emergency events and the mitigation measures to deal with such emergencies

ISSUE MITIGATION STRATEGY Power failure Stop processing, store all fish into coolrooms

and DO NOT OPEN COOLROOMS until power returns, on resumption of power

monitor fish in accordance with Food Safety

Standards

Public safety of premises Premises has an alarm system Table 4 – List of Potential External Risks


19. Public Health The main public health issues are addressed under the following subheadings.

Fly Control If a problem with flies is discovered during a pre operation inspection a fogging knock down fly spray “Settling Day” will be used before production commences. A complete wash down

after fogging would be employed. The same format would be employed if during production

a fly problem existed. A complete clearance of product and the above format will be implemented.

Vermin Control Bait stations will be highlighted in yellow on an internal premises plan. Bait stations to be

clearly labelled “POISON” and are checked weekly by the Manager/QC Officer and recorded

on the Hygiene and Premises Report. HVS engage a reputable pest control firm to bait the premises once per month and report and check all the base stations.

Communicable Diseases HVS has adopted the following procedure with respect to communicable diseases:

No Person, while known or suspected to be suffering from, or to be a carrier of a disease

likely to be transmitted through processed food or while affected with infected wounds, skin infections, sores or diarrhoea, is permitted to work in any food handling area in the

capacity in which there is a likelihood of such a person directly or indirectly

contaminating food with pathogenic micro-organisms.

Any person so affected must immediately report their illness to management.

Injuries Any person who has a cut or wound must not continue to handle processed food or food

contact surfaces until the injury is completely protected by a water proof covering which is firmly secured, and which is conspicuous in colour.

Personal Cleanliness A person in a food handling area must maintain a high degree of personal cleanliness. A

person must not wear any jewellery when engaged in preparing processed food except sleeper

earrings and plain wedding rings.

A person must not wear fingernail varnish if handling food with bare hands.

A person must not engage in any behaviour which could result in contamination of processed

food, such as eating, smoking, chewing anything such as gum, sticks, tobacco or betel nuts, or

any other unhygienic behaviour in food handling areas.

A person who will be engaged in handling food must wash his or her hands at the following

times:

on entering the food handling area immediately after using the toilet

after touching the nose or mouth

after handling contaminated material whenever necessary to avoid contaminating the food in the area


A person who will be engaged in handling food must wash and disinfect his or her hands

immediately after handling any material, which might be capable of transmitting disease.

Protective Clothing A person in a food handling area must at all times:

(a) wear suitable protective clothing and footwear

(b) wear a head-covering that encloses the hair (c) if medium or high risk food is prepared in the area and the person has a beard or

moustache, or both wear a head covering that encloses the scalp hair, and the beard or

moustache, or both; and (d) if the person is wearing gloves – ensure that the gloves are in a sound, clean and

sanitary condition

If a person wears disposable gloves or other disposable protective clothing in a food handling area, the gloves or other clothing must be discarded after use and must not be reused.

Protective clothing worn by a person in a food handling area must not have an outer breast pocket and must be light coloured; and either washable or disposable.

A person in a food handling area must keep protective clothing clean so as not to present a risk of contamination to the processed food.

Protective outer clothing (including footwear, overalls, aprons, headwear and gloves) used in

a food handling area must not be worn outside the establishment.

New and existing personnel are informed of the above hygiene requirements. All personnel

are supervised and trained by the Manager/QC Officer.

20. Sustainability HVS are committed to ensuring the operations meet sustainability principals as much as

possible. They will incorporate several key environmental initiatives including and not limited to:

The existence of a sealed car park with storm water collection points Installation of their own ice making facility and appropriate disinfection procedures

Compliance with full AQIS requirements for export of their product

Continued use of the existing 2700 septic tank as a tool for pre-treatment / capture of any sludgy waste generated

Landscaping and bordering with native plants and trees

21. Monitoring & Review Monitoring is to be conducted in two parts – quarantine and environmental.

As part of the quarantine requirements there will be a comprehensive program of monitoring

for the following aspects of the operations:

ice water chlorination

sanitation


Ice is to be manufactured from potable standard water, which conforms to Export Control

(Processed Food) Orders – Schedule 2, 24.1. The water is to be sampled not less than

monthly during periods of operation, or more frequently if required. Samples are to be analysed at a NATA registered laboratory and records are to be retained on the premises.

AQIS regional office to be notified in writing by fax within 2 working days of receipt of the

results of examination of any sample of water / ice if it does not comply with the following

any E. coli per 100 ml more than 10 coliform organisations per 100 ml

any two consecutive samples containing 1 to 10 coliforms per 100 ml

any three samples containing 1 to 10 coliforms per 100 ml in any consecutive 12 month period

There is to be a chlorination program for processing water. All process water will be

chlorinated and readings taken once daily by the Production Manager. The readings are recorded on the Daily Hygiene Report. A residual chlorine level will be maintained.

HVS is to have a Listeria sampling and testing program. Listeria analysis results are to be kept on the premises and are to be available for inspection by authorised AQIS personnel.

Testing will be performed by a NATA registered laboratory.

Environmental monitoring will occur with respect to:

wastewater quality and quantity

odour audits

solid waste generation

Wastewater monitoring for quality and quantity will occur as part of a Trade Waste

Agreement with Southern Water. Compliance with water quality objectives of the sewage discharge is expected to be met. Parameters to be analysed will be:

pH

temperature Chemical Oxygen Demand

Biological Oxygen Demand

Total Suspended Solids

Floatable Oils and Grease Rate of Discharge

Odour audits (see section 6) are also proposed to be undertaken if there are any odour complaints.

HVS will review the Environmental Management Plan at an interval of between 3 and 5

years. Reviews should include a comparison of the actual operation versus any predictions with respect to solid waste, noise, odours, trade waste and hygiene made in this document.

All personnel are supervised and trained by the Manager/QC Officer.


22. Responsibilities The standards of Personal hygiene are outlined below.

Dress Code It is a requirement that clean factory issue overalls or coats be worn in the processing areas at

all times.

These overalls or coats must be clean and kept in a hygienic condition. Street clothing is not allowed into processing areas. Overalls, dustcoats etc must be removed before leaving the

premises for the day. Items taken home for washing must not be worn home.

Anyone entering a processing area must wear clean approved gumboots. These can either be gumboots for process workers or leather ankle boots or approved shoes for other staff. No

other footwear is acceptable. Gumboots worn outside the factory must only be worn in transit

between the factor and amenities block. They must not be worn home e.g. off concreted

areas. All personnel entering a processing area must wear factory issue hat. These hats are either

bump hats or soft cloth hats for process workers. All loose hair should be tucked into the hat.

In addition all beards and moustaches must be covered. All hair clips or grips or hair bands must be contained inside the hat, or else removed from the

hair.

Used gloves must be disposed of correctly in the bins provided

Entering processing areas

All boots and gumboots must be sanitised by walking through the footbath positioned in the

main entrance to the processing area. All personnel must wash their hands upon entering and leaving the processing area.

Hands must be washed after going to the toilet - every time.

Street clothing Jackets, jumpers and all other street clothing are not allowed to be worn over overalls in

processing areas.

The top layer of clothing worn in processing areas must be dust/laboratory coat, and warm clothing or jackets should be under these overalls.

No jackets or jumpers are to be left in the processing area. They should be kept in the lockers

provided in the amenities.

Smoking Smoking is strictly forbidden in all processing areas, lunchroom, and fish receivable areas.

Eating

Eating food, including soft drink, and chewing of gum in the processing areas is strictly

forbidden.


First aid dressings It is important that all cuts and sores are covered with an approved dressing and the dressing be covered with a fingerstall or waterproof glove if on the hands, and a sleeve cuff if on the

arms. These can be obtained from the first aid room as appropriate.

If any dressing should get lost during production, then the supervisor should be informed immediately so it can be retrieved.

Sleeves on clothing All personnel handling fish must either roll up their sleeves to above the elbow or wear

protective sleeve cuffs.

Watches

No watches of any sort are to be worn in the processing areas.

Jewellery Because of the serious risk of contamination of product, the wearing of jewellery in

processing areas is prohibited. The only exceptions to this are plain wedding bands.

However if a wedding band contains stones of any sort, then a glove must cover it. Bracelets, brooches, bangles, chains, earrings, nose studs etc., are not permitted.

Nail polish Because nail polish can chip off and some has been found in product which has caused

customer complaints, the wearing of nail polish is forbidden, except when covered by a glove,

at all times.

Wearing of aprons All process workers are required to wear approved aprons as issued and should be kept clean

at all times and always tied back. Personal issued aprons should be used at all times, no on else's.

Sickness Anyone showing symptoms of diarrhoea or vomiting must advise their supervisor or management immediately and go to the doctor for treatment. Under no circumstances must

anyone work in processing areas when they have the above symptoms, as we risk

contaminating product.

Drivers Truck drivers and forklift operators are to obey all safety requirements and to make sure their vehicle is cleaned inside and out at end of use

General All rubbish to be placed in containers provided. Anyone who works on processing lines must report to supervisor immediately any item is

found to be missing and which may have fallen into product. i.e. contact lenses, parts of

spectacles, false teeth etc. We must do everything we can to avoid product contamination


PART D - ENVIRONMENTAL

PART E - CONSULTATION PROCESS

Consultation has been undertaken with the Huon Valley Council and the Environment

Division as follows:

Discussions with Mr Glen Doyle (General Manager) Huon Valley Council and

Mathew Grimsey at the Huon Valley Council offices

Meeting with Dr Sarah Richards (Environmental Scientist) from the Environment

Division on 29 April 2010

Meeting with Dr Judi Marshall of Southern Water on 29 April 2010

Discussions and review of drafts of this report with Mr Shane Hogue

The EPA officers have indicated that the project is likely be a Level 2A project however this

is a matter to be determined by the Director of the EPA. In making this determination consideration needs to be taken into account the fact that the Huon Valley Council does not

require a Development Application for a new planning permit. Also historically this site has

been has very heavy processing of abalone and other foods with regular truck movements and

has not had a history of any complaints or concerns from the community of Council

HVS have prepared this EER as part of its application for the extension of operations to

include contract processing of fish and fish products. The existing permitted use is not expected to have any significant alterations, or changes or additions to transport movements,

solid waste, odour or noise levels. Wastewater discharges are a matter to be resolved with

Southern Water.

AND ANALYSIS

Environmental Effects Report for Huon Valley Seafoods, May 2010

49

Huon Valley Seafoods Field report for noise monitoring, 2/3/2009 and 12/5/2009

General

The blast freezer operation at 49 Wilmot (Ranelagh) Rd is extending noise to the neighbour at

“Inlet Farm”, 49 Wilmot Rd. The neighbours report noise facing the plant, inside adjacent

rooms, and on the riverside of the house (reflecting off the cliffs on the other side of the Huon

River. The house is double brick with steel over a shingle roof with ceiling insulation. The

windows would appear the main noise conduit.

The blast freezer operation (24 hr when in use) occurs post harvest times for various clients at

different times of the year. Some enclosure and dampening treatment has been undertaken on

the plant. The HVS also attempts some physical shielding by positioning stacks of containers

and parking of a truck.

The main source of the complaint was found to be mid-frequency tonal noise from the freezer

compressor plant, combined with the low frequency broadband noise eof the circulatory fan

systems.

height.

Location 5. 1.0 m from walls, inside lean-to compressor enclosure, microphone at 1.2 m

height.

Comments

The outside walls of the compressor enclosure vibrate; an indication of structural

conduction of noise via the internal struts to the roof. During the visit, the compressor/s

were on 50-60% of the time.

. There are unshielded holes in the ceiling and doorway wall of the enclosure.

. The two electric compressor motors, both rated at 2900 rpm, work simultaneously at

times, resulting in interference beating, additional to an 800Hz tonal feature.

The main shed emanates broadband low frequency noise.
