EXECUTIVE SUMMARY
Blantyre Farms Pty Ltd proposes to build a piggery complex to house 2200 sows and their progeny on “Eulie”, Eulie
Road, Harden NSW. There will be a breeder & a grower site, located approximately 1km apart. The breeder site will
house 7400 pigs and the grower site 18,000 pigs. The pigs will be housed in modern sheds with 5 sheds at the
breeder site and 16 sheds at the grower site.
Both effluent systems will incorporate a methane digestion system, which involves covering the main effluent dam,
capturing the biogas and using it to run a generator, which makes power for the site. SEP’s (long contour banks) & a
recycle dam make up the remainder of the effluent system.
The impacts of the development are capable of being managed in a way to minimise harm and risk. The odour wll be
significantly reduced as a result of the main effluent pond being covered. A recommended separation distance has
been calculated, all neighbouring houses fall outside this distance.
Soils have proven suitable for constructing effluent dams. The existing farm, Eulie, owned by the proponents is
capable of utilising all nutrients generated from the waste of the pig farm.
The ground water is a significant distance below ground level. The sites are a reasonable distance from both
Cunningham and Maniac Creeks. A monitoring program will be put in place to ensure pollution of surface or
groundwater does not occur.
Only one small tree needs to be removed for the whole project and aboriginal heritage assessments have been
conducted with no significant findings.
There will be approximately 13 semi-trailer truck movements per week, along the Jugiong Road and Eulie Road. It is
planned to seal a section of the road past the Carnbrae house to minimise the impact of dust and noise. Ramps will
also be upgraded.
Blantyre Farms currently operates a similar size farm at Young & is recognised as an environmental leader in the pig
industry.
At completion of the development, it is expected that an additional 20 full time people will be required. The piggery
will also be a large user of feed quality grain, which where possible will be sourced from local farmers. This should
have a significant positive flow on effect for the Harden community.

OBJECTIVES AND CHARACTERISTICS
B.1.a Pig Numbers
The proposal is to construct a breeder and grower site, comprising 2,200 sows and their progeny. Maximum total
capacity is 25,113 SPU (standard pig units). This is the total pigs that will be housed at any point in time once the
project is completed. The below table provides a breakdown of pig numbers and types.

Pigs will be sourced from a high health herd and after initial inputs will become a closed herd, meaning replacements
will be bred from within, only semen will be imported.
Strict biosecurity measures will be adhered to, which includes a minimum time away from contact with other pigs, a
minimum time away following overseas travel, providing site clothes & shoes for all visitors & maintaining log books
of visitors to the sites. All these factors help minimise the risk of biosecurity outbreaks.
B.1.b Method of Production
Pigs will be produced indoors in conventional buildings, this means a concrete base with raised slatted floors for the
manure to drop into the pit below, which is flushed daily.
At both sites, buildings will be constructed of concrete flooring, steel frames and white sandwich panel walls and
rooves. The buildings will have automatically controlled natural ventilation, this means the blinds that are the full
length of the shed, will open and close automatically, controlled by a thermostat, this maintains optimal
temperatures within the shed for the pigs comfort. The farrowing sheds will be fully insulated and climate
controlled, meaning they will have
Some pictures of similar sheds are below.

an office/amenities block, this will be made of white panel
a maintenance shed, which will be constructed of a concrete floor & beige colour bond walls and roof
a shed housing the feed system, which will be constructed of a concrete floor & beige colourbond walls and
roof
The hours of Operational activities
Both sites will operate during daylight hours between 7am and 5pm, to suit employed staff and avoid potential
nuisance.
B.1.d The number of Employees
It is expected that an additional 20 full time staff will be required at completion. Approximately 10 additional full
time staff will be required for construction.
B.1.e
The Volume and Nature of Wastes, including Water, Nutrient & Salt balances
A similar effluent system will be constructed to the one at Blantyre’s other farm in Young. This has successfully been
operated since construction.
Waste quantities are estimated to include 616 tonnes/year of solids from the SEP’s, which will be stackable, easy to
cart & very low odour. 40 ML/year of recycle liquid to be irrigated on paddocks at Eulie. Calculations for these figures
are at Annexure F.

Waste handling, Treatment & Utilisation
Manure is flushed daily from sheds to covered pond. The liquid goes from the sheds, to the covered dam in
pipes.
Liquid waste water is drained from covered pond continually to the recycle dam or SEPS
Recycle liquid is used to flush sheds. This is pumped from the recycle dam to the sheds. This liquid is not
treated.
Excess recycle liquid, not used for flushing sheds, is irrigated on paddocks as a once per year fertiliser
application. This is done using a travelling irrigator, recycle liquid is sprayed out of the irrigation while it is
pulled by a wire rope, when one run is complete, the irrigator is moved to the next run. Approximately 20ml
of liquid waste is applied on the ground with each pass, this low application rate limits run off. The runs are
across slopes, not down slopes, to minimise run off. This type of irrigator is most suitable to the topography
and quantity of recycle liquid. Drip irrigation is not suitable for application on pasture and the topography of
Eulie does not suit centre pivot irrigators.
Biogas is used to run generator or is flared.
Solid waste is pumped from the covered pond about four times per year to the SEPS & dried out annually.
Dry manure is cleaned out of SEP’s annually and spread on farm as fertiliser or can be sold off farm. It is
unlikely that it will be sold off farm, however if this was required, it is a dry, stackable solid that can easily be
transported.

All 1800 hectares of Eulie will be utilised for solid and liquid effluent reuse. As shown in B.1 e above, Eulie is
large enough to utilise all nutrients from liquid and solid waste.
Exclusion zones will be maintained for the spreading of liquid effluent of 20 metres from gullies, creeks and
the Eulie boundary, these exclusion zones are shown on the paddock map as Annexure B.
No bedding is used.
The following diagram shows the operation of the effluent system
Carcasses from dead pigs and after birth will be composted using spent manure & straw. Carcasses will be covered
with straw to discourage vermin & reduce odour. When bodies have composted waste will be removed and used as
fertiliser on Eulie. This will be situated in a controlled drainage area. This is best industry practise for disposing of
dead pigs, the straw covering reduces odour and provide carbon for the composting process. It is expected to use
about 50 large square bales of straw annually, this may be produced on farm or purchased.
A contingency site for mass burials has been identified at Eulie, this is marked on the Eulie paddock map at Annexure
B. This area is similar in topography to the breeder site and is a significant distance above the water table, it is similar
soil structure to the breeder site, which indicates the soil type which would prevent leaching to the water table. It is
not near any residential dwellings and nor is it close to Cunningham Creek or Maniac Creek.
B.1.g Crop management and nutrient removal
Eulie is 1804 hectares, it operates a productive cropping and grazing operation. All of the waste generated from the
pig farms will be able to be sustainably used on Eulie. Spreading of SEP solids and liquid effluent will be in
consultation with the Eulie agronomist, to ensure nutrients & salts are not overloaded.
When applying manures or fertilisers to soils, a proportion of the phosphorus is adsorbed (ie bound tightly) to the
clay mineral particles and or forms insoluble phosphate precipitates with soil minerals such as Iron. This fraction of
the applied phosphorus is subsequently very stable in the soil and unavailable for immediate plant uptake. Given the
bulk density of the soil is 1.3 to 1.4, and the P Sorption capacity of the soil, it is estimated that of the phosphorus
12
Eulie Pig Farm EIS
applied, 30 kg/P/ha/yr would be fixed by this process. This amount can be added to the soil in addition to plant
uptake needs.
The table below shows a typical break up of production for Eulie, this can be adjusted as required to help balance
nutrients. This shows that Eulie can sustainably use all nutrients produced by the pig farm.

Salt in effluent is mostly potassium chloride, not sodium chloride. This is addressed by the potassium removal in the
table above.
The proponents have no intention of selling any part of Eulie. However if land was sold, there is a market for pig
manure and solid pig manure could easily be sold off farm. This would ensure that with a smaller land area that the
nutrients could be managed.
B.1.h Volume and nature of truck movements
Peak Traffic Volumes will be 13 truck movements per week or 1.9 truck movements per day.
Estimates are based on Blantyre Farms current activities on its existing pig farm, which is a similar size, at Young
NSW.

Initially breeding stock will be brought in via truck, after this the herd will be closed and replacements sourced from
within. There will be no vehicle movements for pigs coming in.
At completion pigs will be exported from Eulie to Melbourne. Pigs are sold on a continual basis, with between 850 to
900 pigs being sold each week. A semi trailer holds approximately 250 pigs per load. Pigs will primarily be loaded
with pigs between 7 and 8am, with trucks departing once loading is complete. Pigs are predominantly loaded on
weekdays.
Pig manure will be utilised as fertiliser on farm, there will be no external vehicle movements for fertiliser/manure
going out.
Previously Eulie would cart approximately 2,000t of grain off farm, this grain will now be kept on farm and utilised
for pig feed.
Truck movements for feed will mostly come from the Windridge Feedmill at Young, deliveries should predominantly
be after 8am, as the trucks are loaded at the mill at 7am. The freight roster of the mill and truck availability
determines the timing of loads, within the operating hours (7am to 5pm) of weekdays. Feed normally takes up to an
hour for a truck to unload.

Heating and cooling
Factors to assist cooling:
 sheds will run east west (to limit sun exposure for the pigs)
 sheds rooves and ends made of insulated panel
 sheds have automatically controlled naturally ventilated sheds & spray coolers. This means the blinds that
run the full length of the shed open and close based on a thermostat in the shed that optimises
temperatures in the shed for the pigs. Generally blinds will be open in summer most of the time & in winter
during the warmer hours of the day.
 Farrowing house is fully climate controlled and kept cool by evaporative coolers
Factors to assist heating:
 insulated rooves
 pigs themselves generate a lot of heat
 weaner sheds are heated with hot water piped through the rooms
14
Eulie Pig Farm EIS

B.1.j
sucker pigs in the farrowing house are heated via hot water reticulating through under floor pads, this water
is on continuous flow, but is topped up with bore water if required. The water is heated via aheat exchanger
on the generators exhaust, stored in a hot water tank and piped through sheds.
The frequency of effluent pond clean out
This has been discussed in B.1.f Waste handling, Treatment & Utilisation above.
B.1.k Chemical usage & storage
Veterinary chemicals & disinfectant used on the piggery will be kept in a refrigerator or storage room, in a locked
room at both the breeder and grower sites. Proper handling and record keeping for chemicals forms part of the APIQ
Quality Assurance Program, which the pig farm will adopt.
B.1.j
The projected life of the operation
The projected life of the operation exceeds 25 years.
B.1.m Staging
The construction will be continuous unless unforeseen circumstances arise.
The drainage and effluent system will all be constructed first.
Sheds will then be built, some sheds will be utilised before the full site is completed.

DESCRIPTION OF OPERATIONS
B.2.a Location, elevation and materials of building
Location & elevation of sheds is shown on the following maps





Annexure A – Topographic map
Annexure B – Eulie paddock map
Annexure C – Surveyed site map
Annexure D – Drainage map
Annexure E – Site plan
All sheds will be constructed within controlled drainage areas. This means all run off from the sites will be collected
and retained on site.
B.2.b Earthworks, fencing, dams and ponds
The sites have been surveyed. All drainage, stormwater containment, earthworks for building pads, covered pond,
SEP’s and recycle dam areas have been designed by the NSW Soil Conservation Service. Annexure D shows the
designs for these works.
Both sites will have perimeter fences installed for quarantine purposes. This will be 2m high and constructed from
normal farm fencing materials, not chain mesh.
All pig sheds will be constructed of concrete floors, steel frames and sandwich panel cladding walls and rooves..
B.2.c Waste management facilities and effluent holding and utilisation areas
The effluent systems will comprise:
Site
Covered Pond
3 x SEP’s
Recycle dam
Breeder
5.02ML
4.425ML
3.8ML
Grower
15.13ML
14.409ML
11.9ML
There will be room between the SEP’s for machinery access to empty the SEP’s and to hold dry manure before
spreading in a controlled drainage area.
The covers for the covers pond will be made out of 2mm LDPE or HDPE. The cover will be anchored by a perimeter
trench, will be backfilled with dirt & compacted. Poly pipe will be filled with water and held in the middle of the
cover to assist in anchoring the cover. Biogas will be cooled with a chiller & cleaned with a scrubber using iron
feroxide before being blown to a generator, which will turn the biogas into electricity. A flare will be installed to burn
excess biogas and as a backup. Photos of a similar system are below.
16
Eulie Pig Farm EIS
Carcase composting will occur between the bottom SEP and recycle dam, which is also a controlled drainage area.
All 1800 hectares of Eulie will be utilised for solid and liquid effluent reuse. Buffer zones will be maintained for the
spreading of liquid effluent of 25metres from creeks and 10m from the Eulie boundary. This is an adequate buffer as
liquid effluent irrigation is only applied at 10mm, which is very light application rate & will be absorbed into the
ground & not run off.
Solid and liquid waste will be utilised in conjunction with Blantyre’s agronomist and cropping program. When it is not
sustainable to use all of the manure on Eulie, excess SEP solids will be sold.
B.2.d Type of machinery to be used
Mixed feed will be purchased from an offsite Feedmill. Grain will be milled on each site through a disc mill. A liquid
feed system will mix and deliver the feed to the pigs troughs. The liquid feed kitchen is located near the sheds, so
feed is pumped in pipe to the pig sheds.
Any feed spills inside sheds will be contained by the effluent system, any feed spills outside sheds can be cleaned up.
Generally feed spills are less than a tonne in quantity, as the feed system know there is a problem and stops.
Each site will have a small tractor or ute for picking up dead pigs and removing to the carcass composting area.
17
Eulie Pig Farm EIS
Annually a loader or excavator will be used to remove dry solids from the SEP’s and load it onto a trucks to deliver to
the paddock for delivery. A muck spreader will be used to spread solids on paddocks.
A travelling irrigator will be used to irrigate liquid effluent on paddocks. Irrigation happens on most week days in
summer, some summer weekends and occasionally in winter. The irrigator applies about 10mm of liquid fertiliser,
which is a low rate and is quickly absorbed into the soil. The paddocks to irrigate is decided by Blantyre’s
management & their agronomic advice. The decision is based on paddock suitability and nutrient requirement.
B.2.e Silt traps, drainage & storm water facilities
A surface water diversion bank will divert water around the site to normal drainage lines, shown in Annexure D.
Spoon drains beside sheds will catch rainwater from rooves & around shed, spoon drains will drain into a sump &
from there into pipes to the 5ML freshwater dam at each site, also showm in Annexure D.
All manure will be captured, in the pits under the sheds, flushed daily to a sump at the end of each shed & piped to
the covered pond.
Drainage works and stormwater design has carried out by NSW Soil Conservation Service, as shown in Annexure D.
The sheds and effluent systems are located on high ground and cannot be effected by flooding.
B.2 f
Storage area and sheds.
Each site will have one 500 tonne grain silo, three 50 tonne silos and one 30 tonne silo to hold pig feed on site.
B.2.g Processing, storage or loading facilities for transport
Weaner pigs are loaded at the breeder site and unloaded at the grower site using a trailer pulled by a ute. The trailer
will have a ramp for the purpose of loading and unloading.
A loading ramp will be constructed at each site. The loading ramp will have the ability to reach three decks on a
semi-trailer. The loading ramp will be approximately 6m in length and be high enough to reach the top deck of a
semi-trailer. The laneway leading to the loading ramp is fenced to prevent pigs from escaping. The location of the
loading ramp can be seen in Annexure E.
B.3.
SITE LAYOUT
B.3.a Vegetation to be cleared or disturbed
There is one small tree at the breeder site which will need to be removed. No other significant vegetation will be
removed. Information regarding this tree has been provided to the Office of Environment & Heritage, who have
indicated that an assessment on impacts of biodiversity is not required.
The area has been extensively cropped for at least the past 50 years, there is no native grasses or vegetation at
either site.
B.3.b Internal access roads, truck parking, loading & turning areas
An internal road to the grower site will be constructed, there is an existing farm road which extends most of the way
to the proposed site, this will be utilised and further built up with gravel.
Access to the breeder site will come directly off Eulie road to the west of the site
A perimeter roadway around each site, will be constructed to give access to all sheds, silos and loading ramps. There
is excessive space for truck parking and turning.
See B.4.e below for more information & a map.
18
Eulie Pig Farm EIS
Internal roads will be constructed from gravel sources on Eulie. The standard of internal roads will be sufficient to
allow all weather access.
B.3.c Effluent storage, land application areas, controlled drainage areas and waste disposal areas
There will at least 6m between the SEP’s to hold dry manure before spreading, this is in a controlled drainage area.
Carcase composting will occur between the bottom SEP and recycle dam, which is also a controlled drainage area.
All 1800 hectares of Eulie will be utilised for solid and liquid effluent reuse. Buffer zones will be maintained for the
spreading of liquid effluent of 25 metres from creeks and 10metres from the Eulie boundary.
Solid and liquid waste will be utilised in conjunction with Blantyre’s agronomist and cropping program. If it is not
sustainable to use all of the manure on Eulie, excess SEP solids could be sold, this is considered highly unlikely.
B.3.d Site drainage, erosion and sediment control during construction.
Annexure D shows surface water diversion banks, these will be constructed prior to internal earthworks or shed
construction.
Storm water will be collected from the shed site and from above the effluent system, this will be diverted to
freshwater dams at each site, via spoon drains beside the sheds and pipes. These are also shown in Annexure D. This
will minimise the liquid waste in the effluent system.
B.3.e Landscaping
Tree lines will be planted to screen the pig farm. The location of these can be seen on Annexure B. Tree lines will be
at least three trees wide and predominantly of native trees. They will be either seeded of tube stock and will be
planted in winter 2016.

These sizes and volumes have been determined by two models, Pig Bal (Annexure F) and Water Bal (Annexure G).
The PigBal model uses inputs on pig numbers & waste outputs to determine the optimal covered pond size and
design.
The WaterBal model uses effluent quantities, local rainfall and evaporation data to determine the size and design of
the SEP’s and the recycle dam to ensure storage capacity can hold a 1 in 10 year rainfall event. More detail on this in
B.3.g.
A hydraulic conductivity test has been conducted on ten soil samples by the NSW Soil Conservation Service, this has
shown a low permeability, meaning the soil is suitable for construction of effluent ponds with adequate compaction.
19
Eulie Pig Farm EIS
B.3.g Assumption regarding seasonal variations, meteorological conditions and storm events used to
estimate the required capacity.
Annexure G shows report from and an explanation for WaterBal, a model run by Alan Skerman, DAF Qld. This is a
daily water balance model, which uses 50 years of historical rainfall & evapotranspiration data for the site, (this is
Harden, East St data, obtained from the SILO website). It simulates the operation of the effluent storage and
irrigation system, showing graphically the spill events which would have occurred over the 50 year analysis period.
This model states that recycle dam volumes of 3.8 & 11.9ML would be required for breeder and grower units to limit
storage pond spills to a frequency of 1 in 10 years. The sizing of the effluent storage has been based on this model.
Blantyre’s existing pig farm liquid effluent storage is sized in the same manner and has not had an overflow event
since construction. Good management practices also limit the risk of overflowing, this includes keeping freeboard in
recycle dam and seps by irrigating in summer, also ensuring site drainage is functioning well and stormwater runoff
does not end up in the effluent system, minimising leaks in the sheds to keep water out of the effluent system.
Prevention measures for fire and bushfire will be utilised. A fire tanker is currently kept on Eulie and will continue to
be. Fire extinguishers will be placed around both sites. Grass and vegetation around sheds will be maintained at low
levels for approximately a 50m area extending out from the site, particularly in summer. Internal access roads will
provide access to all sheds, these roads will provide a buffer to fires also.
Possible fire sources and mitigation strategies are:



Flares, these will have a 20m gravel pad around them for fire prevention, water will be connected near the
flare.
Generators, located on gravel or concrete bund, extinguishers located at generator & automatic shut off in
generator.
Pig sheds, fire extinguishers and hoses/water access located throughout sheds. Smoke detectors in
farrowing shed with back to base alarm.
B.4 INFRASTRUCTURE AND SERVICES REQUIREMENT
B.4 A Energy supply
New electricity lines & transformers will need to be installed to each site.
At the breeder site an existing power pole will have to be moved. An independent contractor has been consulted
and will complete the required works. Essential Energy will be consulted to ensure their requirements are met.
At the grower site power will be connected from power lines to the south & connected to the site.
The pig farm will generate its own electricity through capturing methane and running it to a generator. Excess
electricity will be sold back to the grid. Connection to the grid is necessary to put power back into the grid and as a
backup.
B.4.b Total water requirements
Water requirement calculations have been determined by Alan Skerman, DAF QLd, using PigBal (a model designed to
determine water usage, amongst other things), a report from Pig Bal is included in Annexure F. This model includes
different classes of pigs & their water requirements, hosing & cooling requirements. The model predicts that the
breeder site requires 15ML per year and the grower site 45ML per year. Maximum water requirements will be 60ML
of water per year.
This is a relatively low quantity of water, for perspective the average cotton crop uses 7.8ML per hectare.
20
Eulie Pig Farm EIS
The extraction of this water from the ground water will not impact the ground water table, as water has to be
purchased from the market, this is only able to be sourced from an existing entitlement in the Murrumbidgee
catchment.
B.4.c Sources of water supply
Some storm water will be captured, in 5ML fresh water dams, from the site, including shed rooves & land between &
around sheds. The approximate area for the breeder site is 181m x 169m = 30,589m 2 & the grower site area of 225m
x 213m = 47,925m2. Using the Harden average annual rainfall of 607mm (see C.3.d), given that 1mm rain equates to
1L/m2, & assuming a 25% soil infiltration, rainwater catch will be approximately 21ML per site per annum or 42ML in
total per annum. These dams will be 5ML in size This will be used in the piggery when storage is over 50% capacity,
at less than 50% dam level the water will be stored for emergency use.
30,000L rainwater tanks will be installed at each site to collect rainwater from office, amenity & maintenance shed
rooves for use in sinks, toilets and showers. The roof areas of the office will be 72m2 and the maintenance shed
100m2, with an average rainfall of 607mm (see C.3.d), given that 1mm rain equates to 1L/m2, rainwater catch will be
104,404L per annum.
The remainder of water will be sourced from groundwater. Existing bores on Eulie do not have the capacity to supply
the pig farms. Two new bores will be drilled, it is planned to locate these near the pig farm sites, so internally
produced power can be utilised. Water reticulation systems will be connected so each bore can act as a backup for
the other.
Following DA approval, an application will be made to the DPI Water for a water access license, works approval and
water will be sourced from the market. This process required development approval before it can be commenced.
Water quality has been tested from an existing bore, veterinarian advice has also been obtained, stating that this
water quality is acceptable for pigs use. The Water testing report & veterinarian advice are attached as Annexure H.
Water for pigs is not required to be treated.
Bore water will be pumped to two header tanks, to be located above each site. These will be hold approximately
200,000L each.
B.4.d Offsite waste disposal requirements
It is unlikely that any waste will be removed from site.
B.4.e Road condition and transport requirements
Semi-trailers (general access heavy vehicles) will be used to cart feed and pigs. These trucks are permissible on Eulie
Road.
Access to both sites is via Eulie road. Eulie Road is unsealed.
Parts of Eulie road will need to be upgraded. This will include widening of 3 stock grids along Eulie Road. (These grids
are marked on the map below), sealing the road for 150m to the west & 100m to the east of the Carnbrae house and
better surfacing on Eulie road for approximately 1km on either side of the Maniac Creek crossing.
Both intersections of Eulie Road with the new internal roads will have stock grids, meaning no recess will be
required. The breeder site intersection has excellent site distance in both directions, visibility is free of trees and
clearly visible from a distance. The grower site intersection is on top of a hill, site distance in both directions is also
excellent.
The intersection of Jugiong Road and Eulie Road does not requires upgrading, as provided by the Intersection
Assessment Report provided by MJM Consulting, attached as Annexure Q.
21
Eulie Pig Farm EIS
Eulie Road currently services three farms, including Eulie. Other road users include trucks and cars coming to and
from these farms. Vehicles accessing the pig farm will comply with speed limits, slow down or stop for stock on road
when correct signage is provided & be considerate of other users.
Map showing access routes to the pig farms & proposed internal roads.
Internal roads connecting Eulie road to each site will be built to allow semi trailer access in all weather conditions
and to minimise routine maintenance. There will be ample space available for construction of turning circles and
truck parking at the sites. The feed system has deliberately been built placed to allow good truck access.
A perimeter road will be built around each site, so farm vehicles can access all sides of the sheds. This will also allow
emergency vehicles access if required.
B.5
PREVIOUS AND EXISTING OPERATIONS ON THE SITE
Eulie has been previously & is currently used for mixed farming, which includes cropping & grazing. Historic soil tests
show no nutrient or salt build up in the soil.
B.6
CONSIDERATION OF ALTERNATIVES
Blantyre Farms already has a similar sized pig farm near Young. The owners & their families live in the area and own
Eulie.
Harden is ideal for producing pigs as grain is competitively priced and readily available and the local climate is
suitable. Labour from the town of Harden should be readily available.
Eulie at 1800 hectares is able to utilise a larger amount of the nutrients generated by the pig farm.
The reasons for choosing the particular sites are:






The area is relatively isolated, there are only a few houses within 3.5 km of each site.
There are no neighbours within the recommended separation distance.
Nearly all the recommended separation distance is on land owned by the proponents.
Road access & other infrastructure distance to the site is reasonable.
The sites are reasonably flat, which makes construction and earthworks possible.
The sites are located a considerable distance from Cunningham Creek & it will not be impacted by the
proposal.
22
Eulie Pig Farm EIS

Only one tree needs to be cleared for the development.
Several other sites on Eulie were considered. Part of Eulie is narrow, as can be seen on Annexure A & B. Sites on the
narrow strip of Eulie were not suitable as a large section of the recommended separation distance fell on
neighbouring properties and the required separation distance to neighbouring houses could not be achieved.
Another site in Road paddock was considered, but was not suitable as the slope of the land did not permit building
sheds in east – west direction and a large amount of native large trees needed to be removed. Other sites were too
close to Maniac Creek. Other sites did not have a sufficient flat area.
The route for vehicles along Eulie Road has been given significant consideration. The other possibility was to use
Bonoak Rd for access. Eulie Road is the best alternative for the following reasons:





Economically more viable
The only downside to Eulie road as the route is the impact on the Carnbrae house from dust and noise, if
Bonoak Road was used this would shift this impact from the Carnbrae house to the Bonoak house.
Eulie Road accesses both sites, the Bonoak Road option would only access the grower site and not the
breeder site
Eulie traffic currently & historically use the Eulie Road for access.
The additional cost of using the Bonoak Road may make the project unviable.

PLANNING INFORMATION
C.1.a Zoning, permissibility and land use constraints
Eulie lands are zoned RU1 Primary Production. The Harden Local Environment Plan (LEP) 2011, at Part 2, Clause 2.3
Land Use table lists objectives of RU1 lands as being:





To encourage sustainable primary industry production by maintaining and enhancing the natural resource
base.
To encourage diversity in primary industry enterprises and systems appropriate for the area.
To minimise the fragmentation and alienation of resource lands.
To minimise conflict between land uses within this zone and land uses within adjoining zones.
To encourage the development of non-agricultural land uses that are compatible with the character of the
zone.
Intensive livestock agriculture is permitted with consent.

C.1.c
Compatibility with existing and potential land uses
The surrounding lands are used for cropping and grazing. There is scope for the proponent to purchase grain from
surrounding land owners. The proposed development appears compatible with surrounding land use and is unlikely
to restrict the use of surrounding land for agriculture.
C.1 d Urban expansion, rural residential development, recreation, tourism or community facilities.
The surrounding lands are highly productive cropping and grazing lands, to the best of our knowledge no
surrounding land have diversified into recreational or tourism uses.
The Harden LEP (2011) permits sub division of RU1 land to a minimum of 40 hectares, however given the distance
from the Harden town, residential encroachment is not to be considered an issue for the proposed sites.
The recommended separation distance as calculated in Annexure K and shown in the map at Annexure A, shows that
nearly all the separation distance falls on land owned by the proponents, so the sites are protected from residential
encroachment.
C.1.e Heritage Items or environmental protection
The OEH administered database includes aboriginal heritage sites within the area. Three recorded sites are within
200m of the study area and the closest is 40m from the study area. No recorded sites are within the area for the
proposed piggery.
High levels of ground surface disturbance from cropping and farming practices have been used for at least 50 years
across the sites.
OzArk Environmental and Heritage Management have conducted an aboriginal archaeology assessment, which
include a site visual inspection. No aboriginal sites or objects were found within the proposed pig farm area. OzArk’s
report is attached as Annexure P.

There is a 45m easement and right of carriageway held by NSW Electricity Transmission Authority, the breeder site
will be located beside this easement and shall not encroach on the easement, as is shown on the surveyed site map
attached as annexure C. The right of carriageway will not be effected by the development.
The grower site is not near either the transmission line or the access for the right of carriageway in the relevant Lot.

Eulie Pig Farm EIS
A schedule of lands is listed at page 2 and title searches are included at Annexure J.
The proponents have no intention of selling any part of Eulie. However if land was sold, there is a market for pig
manure, solid & liquid pig manure could easily be sold off farm. This would ensure that with a smaller land area that
the nutrients could be managed. Accordingly there is no requirement to group lots.
C.2.c
Surrounding roads
Access to both sites is via Eulie road, which is an unsealed road. There are no crown roads in the direct vicinity of
either site.

A contour bank will be constructed above the development, as shown in the drainage plan at Annexure D, this will
divert run off from above the sites, around the sites & to the existing drainage lines.
A freshwater dam will be constructed at each site to catch the storm water and run off from the sheds and
surrounding area. The location of this can be seen in the drainage plans at annexure D.
C.2.e Adjoining communities, dwellings and existing land uses
The recommended separation distance is 634m for the breeder site and 1214m for the grower site.
There are two Eulie houses within the recommended separation distance, both houses are occupied by staff of
Blantyre Farms. Both houses are located on Lot 2, DP 623790, which is the same Lot as the breeder site.
All non Eulie dwellings are located outside this distance. The nearest non Eulie dwelling to both sites is the Carnbrae
house, a rural dwelling owned by the Demestre family. Carnbrae house is 2km from the breeder site and 1.6kms
from the grower site.
Annexure K provides workings for a recommended separation distance as provided by the National Environmental
Guidelines 2010. An unreasonable odour impact is assumed to occur when separation distances between a piggery
and a receptor are less than those calculated using this method.
The proposed site is located 8.5 kms from Harden-Murrumburrah.
C.2.f
Sight lines from dwellings or public places
Both sites will be visible from the Carnbrae house. There are paddock trees between the house and sites which will
partially obscure the development. The Carnbrae house is located on a hilltop, it was not possible to find a suitable
location outside of Carnbrae’s line of sight.
25
Eulie Pig Farm EIS
Tree lines will be planted to further obscure the view of the pig farm from the Carnbrae house. The tree lines have
been placed in the most effective place to minimise the visual effect of the pig farm and take into account the
topography. See Annexure B for the location of the tree lines.
Lochbuie will have a line of sight to the breeder site, the Lochbuie house is 3.5km from the site. A tree line will be
planted between the breeder site and their house to minimise this effect.
Some other farm houses to the north of the grower site will also have a line of sight, they are all in excess of 3.5kms,
so this is not expected to have a significant impact. Nevertheless a tree line is proposed to the north of the grower
site to minimise this impact.
C.2 g Utilities
New electricity lines & transformers will need to be installed to each site. At the breeder site an existing power pole
will have to be moved. An independent contractor has been consulted and will complete the required works.
Essential Energy will be consulted to ensure their requirements are met.
Breeder site proposed location for new power lines
Grower site proposed location for new power lines
26
Eulie Pig Farm EIS
The portion of the power line to the south of Eulie rd is located on a crown road. Permission from the Department of
Lands for an easement will be required.
These areas surrounding the new power lines have been included in the aboriginal heritage study.

OVERVIEW OF THE AFFECTED ENVIRONMENT
C.3.a Surface water and ground water
Surface water drains along drainage lines or gullies to either to Maniac or Cunningham Creeks
The map below shows the location of bores in the surrounding area, their work summaries, provided by the NSW
Office of Water, are attached as Annexure O. The majority of these bores show a water bearing zone of 30 to 40
metres.
The NSW Office of Water advises that works approvals and licences for groundwater cannot be granted until after
development consent has been received, the proponent proposes to apply to NSW Office of Water for works
approval for two new bores and water access licenses.
27
Eulie Pig Farm EIS
A freshwater dam will be constructed at each site to catch storm water & run off from the sheds and surrounding
area. This can be seen in the drainage plans in Annexure D.
C.3.b Geology
Below is an extract from the Cootamundra Geological Series Sheet S1/55-11.
All of the proposed site is located on Young Granodiorite. To the east is the Jugiong Shear Zone. Granodiorite is
described in the Cootamundra, 1:250,000 Geological Sheet as “The Granodiorite of the Young Granodiorite is
remarkably uniform in composition….However, there is textural variation with porphyritic phases virtually always
present..”
The topography is described in the Cootamundra, 1:250,000 Geological Sheet as “varies from steep, tor scattered
hills with relief commonly exceeding 150m, to gently rolling, commonly cultivated ground with little or no outcrop.
The southwestern part of the body tends to have steeper topography and better exposures”.
C.3.c
Soils
NSW Soil Conservation carried out the soil assessment, refer to Annexure L for a full description of soil types and soil
analyses. The report says the soil is suitable for this type of development. The nutrients/manure produced are
capable of being used on Eulie in a sustainable manner, as discussed in B.1.c and B.1.f.
Four proposed Soil monitoring points have been selected on Eulie. These are shown on the Eulie paddock map
attached as Annexure B & detailed below.

THE ENVIRONMENTAL ISSUES
E.1
CUMULATIVE IMPACTS
E.1.a Baselines conditions
There are no known other intensive pig farms, poultry farms in a 25km radius of the proposed farms.
30
Eulie Pig Farm EIS
E.1.b Impact Analysis
The two proposed pig farm sites are 1.5 kms apart. Piggeries are treated as separate sites if the nearest receptor is
more than half the shortest separation distance from each piggery, according to Technical notes, Assessment &
management of odour from stationary sources in NSW, Nov 2006, Department of Environment and Conservation
NSW.
The nearest receptor to each site is the Carnbrae house, it is more than the shortest separation distance, so the sites
are considered separately.
A 20% increase in separation distance may apply, as the separation distances overlap. There are no receptors within
the separation distance or the additional 20% separation distance.
The nearest receptor, Carnbrae house is outside the additional separation distance. As shown in the table below:
Site
Normal separation distance
Separation distance + 20%
Distance to nearest receptor (Carnbrae house)
Breeder
951m
1,141m
2,000m
Grower
1,214m
1,456m
1,600m
The pig farm sites are sufficiently remote from each other not to have cumulative impacts from noise, traffic or dust .
The sites are cleared so there will be no impact on flora and fauna habitats. Tree lines will be planted to minimise
visual impacts.
The Carnbrae house will be able to see both sites, but they are at a sufficient distance and tree lines will be planted
to minimise this impact.
The land use (cropping and pasture for stock) will not be changed from current practise. Nutrients from waste
disposal will largely replace conventional fertiliser used on the properties and will not impact on soil or water
resources any more than conventional broad acre farming currently conducted on Eulie and the Harden district.
Using pig manure as fertiliser should be economically and environmentally beneficial compared to conventional
fertiliser.
E.1.c
Mitigation, management and monitoring
The piggery will design, with covered ponds will minimise odour. Other practices such as flushing sheds daily, phase
feeding (feeding different diets to different aged pigs, to match their nutritional requirements) & minimising feed
wastage all help minimise odour.
The location and capacity of the proposed development means no neighbouring houses are within the
recommended separation distance, even for cumulative effect.
Although it is unlikely to occur, any odour complaints from the two sites will be monitored and managed. This means
if a complaint is received, if known the complainant is visited to see if the odour is detectable, wind direction and
speed at time of odour will be checked, piggery sites inspected to check everything is functioning as expected & try
to determine a source of odour.
Confidence in these outcomes is high.
E.2.
ODOUR
E.2.a Baselines conditions
Refer to Annexure K, Recommended Separation Distances for location and separation of nearest odour receptors
31
Eulie Pig Farm EIS
E.2.b Impact Analysis
A small amount of odour will be generated from the pig farms, sources of odour include the sheds and the effluent
system. Blantyre’s farm at Young, which is a similar size, emits low odour. The closest neighbour at this famr is 1km
from the piggery. Blantyre has not received a complaint in more than five years.
The closest receptor to both sites is the Carnbrae house, which is 2kms from the breeder site and 1.6kms from the
grower site. The Carnbrae house falls outside the recommended separation distance.
Refer to Annexure K, Recommended Separation Distances for calculation of required separation distances. This
shows no receptors fall within the recommended separation distance.
This is a level 1 formula which offers a high level of protection for community amenity. Level 2 and 3 odour
modelling has not been conducted as no receptors fell within the recommended separation distance and further
modelling would likely show a reduced separation distance, as the level 1 formula is relatively conservative and
“gives the largest separation distance of all models”, p108 National Environmental Guidelines for Piggeries, 2010.
“If a piggery can demonstrate a clear pass at Level 1 odour assessment, there is no need to undertake Level 2 or 3
assessment, regardless of the size of the development, unless there are special risk factors.” Technical notes,
Assessment & management of odour from stationary sources in NSW, Nov 2006, Department of Environment and
Conservation NSW. Given the proposed sites do not have a neighbouring house in the recommended separation
distance ( a clear pass )as calculated in attachment K, which is a Level 1 assessment, a Level 2 or 3 assessment is not
warranted.
The prevailing wind is from the south west. Refer Annexure M, Rose of Wind Direction versus wind speed, 1967 to
1980. The nearest receptor from either pig farm in a north easterly direction is more than 5km away.
All neighbouring residences within a 3.5km radius of the pig farm sites are located at a height above the pig sites,
except for Bumgum. The height of sites and neighbour houses is shown below:

Eulie Pig Farm EIS
The above map shows drainage lines and the most likely direction of katabatic drift. Katabatic drift is the movement
of cold air down a slope, generally under stable atmospheric conditions. Under such circumstances, dispersion of
odour is generally slow and the associated impacts can create stronger concentrations of odour.
Given the undulating nature of the local terrain, some local katabatic air drainage effects are anticipated but would
not be expected to significantly affect neighbouring residences. The Woburn house is downstream of the drainage
lines, following the drainage lines it is approximately 5 kms from each site. Given the long distance to the house, the
tress along the creek that will disperse odour, the trees to be planted by the proponent and that calm conditions are
present only approximately 30% of the time, it is not expected that the Woburn House will be significantly affected
by the katabatic drift.
Temperature inversions occur most often when a warm, less dense air mass moves over a dense, cold air mass. This
can happen for example, when the air near the ground rapidly loses its heat on a clear night. In this situation, the
ground becomes cooled quickly while the air above it retains the heat the ground was holding during the day.
Inversions are more likely to occur between sunset and two hours after sunrise. This can lead to more concentrated
odour, as it cannot escape through the inversion surface between the cool and warm layers. This is not expected to
cause an issue with the proposed development as nearly all receptors are located above the height of the pig farm
and are a reasonable distance from the sites. The Bureau of Meteorology was consulted and asked to provide data
on atmospheric stability, this data was not available for the Harden area.
E.2.c
Mitigation, management and monitoring
The piggery will incorporate best management practices and design which helps minimise odour, such as flushing
sheds daily, phase feeding and covered ponds.
The location of the sites complies with recommended separation distances, no nearby residences will be effected by
the prevailing wind and katabatic drift is not anticipated to effect any neighbouring residence.
Although it is unlikely to occur, any odour complaints from the two sites will be monitored and managed.
Confidence in these outcomes is high.
33
Eulie Pig Farm EIS
E.3 WASTE MANAGEMENT
E.3.a Baselines conditions
The proponent uses some chicken litter waste at present and synthetic fertiliser as part of the cropping and grazing
program on Eulie.
Blantyre Farms operates a similar waste management system at their pig farm at Young. This has been efficient and
successful. This is described in B.1.f.
E.3.b Impact Analysis
Calculation and discussion of wastes generated and management measures for the proposed pig farm are detailed
extensively in sections B.1.e to g and B.2.c.
Eulie is 1800 hectares, it operates a productive cropping and grazing program. This program currently is able to use
all of the nutrients that will be produced by the proposed pig farm, as is shown in B.1.g.
Waste minimisation is achieved through ensuring feeders are not blocked, they are turned off when a pen is empty,
and not over filled; this minimises feed waste entering the waste system. Phase feeding is also used to ensure pigs of
different ages are provided exactly what their nutrient requirements are. Water waste is minimised through
appropriate selection and well managed drinkers and drinker bowls (drinker bowls catch water spilt by pigs & allow
it to be consumed) , storm water from pig shed rooves is diverted away from the effluent system.
The proposed effluent system at both sites has been designed to hold a one in ten year rainfall event, as outlined in
Annexure F attached. The total storage for each effluent system is outlines in 8.3.f, this is sufficient to hold rainfall on
the uncovered effluent ponds and their catchment area and still have some freeboard given a 1 in 10 year rainfall
event.
E.2.c
Mitigation, management and monitoring
Blantyre’s pig farm at Young has been managed since inception to always have adequate space for wet weather
events and has never had a spill event from its effluent system. This effluent system has been in place for 15 years.
The effluent system is the same as the one proposed for the new development.
Freeboard in the SEP’s and recycle dam is maximised at every opportunity. Management practices of irrigating in
summer frequently, keeping all drains unblocked so all storm water (uncontaminated water) is directed to the
freshwater dam, not the effluent system, draining liquid from SEP’s to the recycle dam & emptying SEPS in summer
as they are dried out. All these practices will ensure maximum freeboard.
Confidence in these outcomes is high.
E.4 WATER QUALTIY AND CATHCMENT PROTECTION
E.4.a Baselines conditions
Surface and groundwater are discussed in C.2.d, C.3.a and C.3.h. There are two creeks on Eulie, Maniac Creek &
Cunningham Creek., both are permanent creeks.
NSW Office of Water bore drilling records in the area show a water bearing zone of more than 30m.
The Harden LEP, Natural Resources Map shows the sites are located in a groundwater vulnerability area, as is half
the Harden Shire.
There are no known occurrences of dryland salinity on Eulie. No saline discharge areas have been observed.
Historical soil tests also show low salinity.
34
Eulie Pig Farm EIS
E.4.b Impact analysis
There is minimal danger of flooding of the proposed pig farm sites, as a result of the topography.
There will be no access of pigs to these creeks.
Spreading of solid waste significantly reduces the risk of surface or ground water contamination, as it is solid in form
and does not flow. It stays where it is placed.
Some liquid waste is inevitable. This can be minimised and managed to ensure safe application.
The risk of impact on the ground water quality from liquid effluent, either stored in dams or irrigated on paddocks is
low. The deep water table, the low permeability of soils and construction/compaction techniques mean risk is very
low.
There is some risk of impacting the surface water from irrigation. Irrigation can be managed in a safe and sustainable
manner to mitigate this risk, which results in low risk of surface water contamination, see below for techniques on
minimising this risk.
E.4.c
Mitigation, management and monitoring
All sheds will be constructed with impervious concrete bases to prevent leaching of contaminants.
All rainfall that lands on effluent ponds, the carcass composting area or alleys for moving pigs, which could be
considered contaminated runoff will be contained & diverted to the effluent system. Carcass composting will take
place on an impermeable gravel pad & contained areas.
Effluent holding structures will be built with required level of compaction, this will be determined in conjunction
with the NSW Government Soil Conservation Service. Soils have proven suitable for permeability to prevent leaching
of contaminants, as detailed in the soil monitoring report (Annexure L).
Liquid waste will be minimised using appropriate selection and well managed drinkers and drinker bowls, storm
water from pig shed rooves is diverted away from the effluent system, and all cleaning possible is done using high
pressure hoses or pressure cleaners that minimise the quantity of water used.
The risk of leaching to groundwater is reduced by the spreading of solids, the SEP system uses evaporation to reduce
the quantity of liquid effluent produced. The SEP system produces less liquid waste than any other effluent system
that can operate with conventional sheds. The SEP system is described in B.1.f.
Application of solid and liquid effluent at light rates, up to 5t/ha for solid effluent & 20ml for liquid effluent. These
light rates & the ability for the Eulie farm to utilise all nutrients as detailed in B.1.g will ensure a sustainable system.
The undulating nature of the Eulie landscape makes irrigation more difficult, however the slope of the hills are not so
great that it makes it not possible. Irrigation will not be carried out near either Maniac or Cunningham Creek. The
paddock map attached at Annexure B shows exclusion zones for liquid effluent. Run off from the irrigator is
minimised by:




The irrigator will run across slopes, so run off does not accumulate & flow down hill.
Low application rates of 20ml will maximise infiltration in the top soil & reduce run off.
Ground cover will be maintained to ensure run off does not occur.
Equipment will be maintained in good order to ensure nozzles do not block and the irrigator operates
correctly.
35
Eulie Pig Farm EIS
A piezometer will be installed below each site to a 10 metre depth immediately below the controlled drainage areas
and effluent system. These piezometers are designated monitoring points BH1, BH2 & BH3 and are shown in the Soil
report by NSW Soil Conservation attached at Annexure L. They will be installed to detect any plumes that may arise if
leaching eventuates from the sheds, effluent dams or carcass composting area.
Confidence in these outcomes is high.
E.5
LAND CAPABILITY AND PROTECTION
E.5.a Baselines conditions
A soil assessment was undertaken by NSW Soil Conversation Service, see Annexure L. Baseline soil analysis can be
found in the historical soil tests attached as Annexure I. These show the land is suitable for this type of development.
E.5.b Impact analysis
Soils have been discussed inc.3.c above.
Eulie is a productive cropping and grazing property. Soil tests show it is suitable for plant growth.
Currently fertiliser is imported to Eulie, following the completion of the proposed development, very little external
fertiliser will be needed. This makes Eulie more sustainable and self-sufficient.
E.5.c
Mitigation, management and monitoring
Solid and liquid effluent will be applied sustainably and in conjunction with agronomic advice. B.1.g shows that Eulie
can sustainably use all the nutrients the pig farms will produce. Farming programs can be adapted to manage
nutrient uptake or solids can be sold off site, although this is unlikely.
The use of organic fertiliser is likely to improve soil structure and thus reduce soil erosion and any other form of soil
degradation. Soil structure is capable of utilising the nutrients available from the pig manure.
Four soil monitoring points have been chosen for annual testing, this will allow management changes to be made to
adjust solid and liquid application across Eulie for sustainable reuse.
Confidence in these outcomes is high.
E.6
DRAINAGE AND STORM WATER MANAGEMENT
E.6.a Baselines conditions
Storm water currently follows natural drainage lines to creeks. Currently creek and gullies areas are kept with some
vegetation cover to minimise erosion and sedimentation of creek areas.
E.6.b Impact analysis
Contaminated water will be kept out of surface water and watercourses. This is easily achieved by planning drainage
of the sites. Stormwater, drainage runoff controls and freshwater dams have been designed by Peter Kirwan, NSW
Soil Conservation for each site, see Drainage plan in Annexure D. The drainage plan will ensure that surface water
and watercourses are not affected by the development.
E.6.c
Mitigation, management and monitoring
Storm water is collected around the sheds and effluent system where possible diverted to a freshwater dam at each
site. This minimises the water entering the effluent system and provides a source of freshwater. Freshwater will be
used as emergency water in the pig farm. It does not need to be treated before use.
All effluent and water that has been contaminated will be contained by the effluent system. This includes rainfall on
uncovered effluent ponds or carcass composting.
36
Eulie Pig Farm EIS
A spoon drain will be constructed on each side of each shed, this will catch the storm water from the rooves and
beside sheds to be diverted to the freshwater dams. The spoon drain will be vegetated to prevent erosion.
Stormwater collected on top of the covered ponds and around the covered pond will also be diverted to the
freshwater dams at each site.
Above each set of SEP’s a contour bank will be constructed. This is to keep stormwater out of the effluent system,
this contour bank will catch stormwater to be diverted to the freshwater dams.
This system is effective at Blantyre’s pig farm at Young and has worked successfully since construction.
This drainage plan will prevent erosion both in the construction phase and once the piggery is completed.
Post construction the piggery site and dam banks will be planted with perennial grasses to ensure erosion does not
occur.
Confidence in these outcomes is high.
E.7
FLOODING
E.7.a Baselines conditions
Pig sites are at least 40m above the height of the Cunningham Creek and at least 20m above Maniac Creek. The
topography is undulating.
E.7.b Impact analysis
Eulie land, shed sites and effluent systems are not subject to flooding.
E.7.c
Mitigation, management and monitoring
Natural topography and site location ensures this is not required.
Confidence in these outcomes is high.
E.8
TRAFFIC AND ROAD IMPACTS
E.8.a Baselines conditions
Access to the proposed pig farms will be via Jugiong Road and Eulie Road. Jugiong road is sealed and the
development will not significantly impact current traffic flows.
Eulie road is not sealed & has low traffic volumes.
E.8.b Impact analysis
Peak Traffic Volumes will be 13 truck movements per week or 1.9 truck movements per day.
Detailed information on truck movements is provided in B.1.h. Detailed information on access and road upgrades
required is provided in B.4.e.
Eulie road is an unsealed public road, it passes in close proximity to the Carnbrae house. Noise generated from truck
movements on Eulie Road may be audible at the Carnbrae house. Dust generated from truck movements on Eulie
Road may impact the Carnbrae house.
1.9 truck movements per day would not be expected to create a significant impact.
37
Eulie Pig Farm EIS
E.8.c
Mitigation, management and monitoring
Upgrades required to Eulie road will include sealing 150 metres of road to the west and 100m to the east of the
Carnbrae house, this will reduce the impact of noise and dust for the Carnbrae house.
All trucks coming to the piggery sites will comply with speed limits on Jugiong and Eulie Road. They will consider
other users on the road & slow down or stop for stock on roads. Therefore they should not impact on other road
used safety.
Internal roads will be well maintained and are a significant distance from any neighbouring residences, traffic on
internal roads will not impact on other road users.
Confidence in these outcomes is medium, as it is a public road and the proponent cannot control this.
E.9
NOISE
E.9.a Baselines conditions
The closest receptor is the Carnbrae house at 2kms from the breeder site and 1.6 kms from the grower site.
Some farm noise is currently generated from tractors, trucks and animals.
E.9.b Impact analysis
There may be minimal impact of noise from the development, however is it expected to be minimal and inaudible at
the nearest receptor.
The methane digestion system includes a generator at each site, which will operate constantly and creates a low
level of noise. The level of noise at 1m will be 80db or less.
As a general rule the Sound Pressure Level (SPL), measured in decibels (db), will decrease by 6 db with a doubling of
distance from a point source. At 1m the SPL of the generators is 80db, at 1000m from the generator the noise will be
20db. Given there are no receptors within 1km of either piggery there will be no impact of noise from generators on
any neighbouring residence.
Other noises at pig farms normally arise from feed milling, stock feeding, stock movements, machinery operation
and vehicle movements. This activities are generally undertaken either intermittently or at regular intervals of short
duration, generally less than one hour.
Machinery noises would be similar to those made on extensive farms and those made at Eulie before the
development.
Trucks travelling on the Eulie Road will create additional noise, the Carnbrae house is the only receptor of this noise.
The NSW Road Noise Policy from the NSW Government Department of Environment, Climate Change and Water
provide a table of common sources of noise, which is copied below.
38
Eulie Pig Farm EIS
There will be on average 1.9 truck movements per day, assuming trucks travel at 50km/hr (this is the normal speed
travelled by a semi-trailer on this part of the road), the noise will affect the Carnbrae house for 150m either side of
the house, at this speed trucks will take 23 seconds to pass the Carnbrae house or 46 seconds per truck movement
or 87 seconds per day.
The NSW Road Noise Policy provides:





Day hours are 7am to 10pm (15 hours)
Night hours are 10pm to 7am (9 hours)
Average maximum one hour noise level is calculated using 15 minute intervals.
The equivalent sound pressure level (ie the steady sound level that over a specified period of time, would
produce the same energy equivalence as the fluctuating sound level actually occurring) representing the
average maximum one hour noise level requirement for the day time period is 55db for local roads. This is
for existing residences affected by additional traffic on existing local roads generated by land use
developments.
The equivalent sound pressure level for night time is 50db.
Using 87 seconds of truck noise per day, 90db for truck noise level & 30db for no truck noise level. This equates to 1
x 15 min interval at 90db & 59 x 15 min intervals at 30db. This gives an average day noise level of 31 db. Which is
well below maximum limit of 55db required in the NSW Road Noise Policy.
No planned truck movements are expected at night. If any unplanned night truck movements occur, this will still fall
well below the night period maximum level of 50db per the NSW Road Noise Policy.
The NSW Road Noise Policy also requires relative increase criteria from a new land use development. This requires
new developments to not create an increase in equivalent sound pressure level more than 12db. The additional
39
Eulie Pig Farm EIS
truck movements from the proposed pig farm, create a 1db (31db – 30db) relative increase in noise for the Carnbrae
house, this is well within the minimum requirements.
E.9.c
Mitigation, management and monitoring
The large separation distance to neighbours mean that noise impacts from the site will be minimal and no worse
than normal farming operations in the area. Operating hours mean most noise is generated during daylight hours
and limits evening noise impacts.
Pigs will be fed ad lib at the grower site and mostly ad lib at the breeder site. This means the majority of pigs have
feed in front of them at all times and there is less frequency of pigs creating a noise at feeding time.
The generators are housed in a container and have mufflers, both these design features reduce the noise. At
Blantyre’s farm near Young they are not audible at the boundary and no complaints have been made regarding the
generator operation ever. The generators will not be audible at neighbouring residences.
Truck noise will mostly be during the day, it is well below maximum levels according to the NSW Road Noise Policy,
as discussed above. In addition the road will be sealed for 150m to the west & 100m to the east of the Carnbrae
house to help minimise road noise.
Confidence in these outcomes is high.
E.10
DUST
E.10.a Baselines conditions
The closest receptor is the Carnbrae house at 2kms from the breeder site and 1.6 kms from the grower site.
Some dust is currently generated from farming practices.
E.10.b Impact analysis
In piggery operation dust emissions tend to originate from either site operation or transport movements.
Minimal dust is produced in sheds, as feed is a wet consistency. The pigs are kept in sheds or on concrete alleys, they
do not generate dust.
Some dust will be created from unloading feed trucks, the dust created is not significant and settles within a few
metres of the unloading area.
Most feed will be prepared off site, transported in enclosed trucks, stored in enclosed silos and mixed with water
before being fed to pigs. Very little dust is emitted from this process.
Milling grain may create some dust, the dust created is not significant and settles within a few metres of the milling
area.
Solid and liquid effluent has sufficient moisture to limit dust emissions.
Truck movements on Eulie Road will create an increase in dust. The only effected residence will be the Carnbrae
house.
E.10.c Mitigation, management and monitoring
Any dust created on internal roads or at the piggery sites is unlikely to affect any neighbours given the proximity of
the sites and internal roads to receptors.
Truck movements on Eulie Road, which is a public road, will create dust which will impact on the Carnbrae house.
Trucks will drive at 50km/hr or less past the Carnbrae house to limit dust generation. 150m of road to the west and
40
Eulie Pig Farm EIS
100m to the east will be sealed from the Carnbrae house to minimise the impact the dust will have on the Carnbrae
house.
Confidence in these outcomes is high.
E.11. VISUAL IMPACTS
E.11.a Baselines conditions
The surrounding areas to the proposed sites have existing scattered paddock trees
E.11.b Impact analysis
A description of the building materials and photographs of similar sheds have been provided in B.1.b.
Some houses will be able to see the proposed pig farm. The Carnbrae house is the closest house to the development
and will have the most visual impact.
Most neighbours will not be able to see as a result of undulating topography or are at a significant distance which
reduces the visual impact.
The development cannot be seen from the Jugiong road.
E.11.c Mitigation, management and monitoring
There are paddock trees around the sites which will partially obscure the development.
Tree lines will be planted to further obscure the view of the pig farm, see Annexure B for location of tree lines t be
planted. These tree lines have been placed to obstruct neighbouring houses views of the sites.
Confidence in these outcomes is high.
E.12. PEST AND INSECT CONTROL
E.12.a Baselines conditions
There are no significant pests or insects present.
E.12.b Impact analysis
There are no impacts expected. Farm and other animals are excluded from the pigs sheds.
E.12.c Mitigation, management and monitoring
Good management practices such as site cleanliness, hygiene, rat baiting and fly baiting can control insect and
rodent pests. All silos, feed bins & feed lines are enclosed or constructed to deprive rodent and bird access to any
feed. Feed spills are cleaned up as soon as practicable.
A regular rodent baiting program is in place and will be part of the farm APIQ Quality Assurance program. This
includes rat bait stations external to pig sheds and regular inspection of these to top up baits.
Similar practices are in place at Blantyre’s farm in Young and no pest or insect issues exist.
Confidence in these outcomes is high.
E.13. FLORA AND FAUNA
E.13.a Baselines conditions
Eulie and surrounding district has been settled for excess of 150 years with extensive clearing, cultivation of much of
the country. The lands have been cropped and grazed for more than 50 years.
41
Eulie Pig Farm EIS
There are scattered trees in some paddocks and along water cources.
E.13.b Impact analysis
A positive impact due to increased native tree plantings is expected.
E.13.c Mitigation, management and monitoring
The proposed development only requires one small tree to be removed. The proponent will plant in excess of 500
native trees in tree lines.
Confidence in these outcomes is high.
E.14. HERITAGE
E.14.a Baselines conditions
Aboriginal heritage items have been identified by the NSW Office of Environment & Heritage in the area. No known
European heritage items exist at the pig farm sites.
E.14.b Impact analysis
The proposed pig farm is unlikely to impact on aboriginal heritage as Eulie has been settled for at least 150 years and
has been farmed extensively for at least 50 years.
E.14.c Mitigation, management and monitoring
OzArk, Senior Archaeologist Dr Chris Lovell conducted a visual inspection on the sites. High level of ground surface
disturbance were confirmed across all parts of the study area. No aboriginal objects were found during the
inspection. Report attached at Annexure P.
Should any item of heritage or archaeological significance be unearthed during construction, further disturbance will
cease. The item/s will be assessed by relevant heritage authorities and any necessary preservation measures
enacted, before construction continues.
Confidence in these outcomes is high.
E.15. HAZARDOUS CHEMICALS
E.15.a Baselines conditions
Farm chemicals & fuels are currently used on Eulie for cropping and grazing purposes.
E.15.b Impact analysis
No impact is anticipated.
Chemical usage in the piggery will consist of disinfectants, antibiotics, insecticides and rodenticides. Vaccines may be
used for the control of porcine diseases as required. These products are safe to be in the effluent streams and are at
very low levels, they do not impact on waste decomposition.
All products are registered for their respective uses and will be used in accordance with label directions or as
prescribed by a consulting veterinarian.
No new fuel or oil storage facilities will be required, the existing farm storage is sufficient for the new development
and existing practices.
42
Eulie Pig Farm EIS
E.15.c Mitigation, management and monitoring
Pest control measures and medication, chemical and vaccine usage and storage are subject to annual external
auditing and accreditation. This occurs under the Australian Pig Industry Quality (APIQ) assurance program which will
be adopted at the new sites.
Vaccines will be stored in a locked facility.
Confidence in these outcomes is high.
E.16. ANIMAL WELFARE
E.16.a Baselines conditions
Piggeries must comply with the nationally recognised Model Code of Practise for the Welfare of Animal – Pigs
(Primary Industries Standing Committee 2008), the Model Code of Practise for the Welfare of Animals: :Land
Transport of Pigs (SCARM 1997) and the Animal Welfare Code of Practise – Commercial Pig Production (I&I NSW
2009). The latter NSW Code of Practise is prescribed under the Prevention of Cruelty to Animals (General) Regulation
2006.
E.16.b Impact analysis
No impact is expected, as all welfare requirements will be satisfied.
E.16.c Mitigation, management and monitoring
The minimum space requirements (Welfare Code) and the proposed space in the new sheds are shown in the table
below. This shows that the development complies or exceeds all minimum space requirements as required by the
Welfare Code.

Pregnant sows will be housed in group housing, which is not required by law, but part of the Australian Pig industry
voluntarily phase out sow stalls. The design of a feeder stall and group area minimises aggression at feeding time as
each sow is in its own feeder stall & a bully sow cannot access a timid sows feed.
Farrowing sows will be housed in piglet protection pens (farrowing crates) which maximise piglet survival. This is the
most effective way to limit the number of piglet deaths from the sow squashing the piglets.
Staff will be trained in animal handling and animal welfare requirements. All pigs will be inspected each day to
ensure their welfare is maintained. Sick pigs will be treated in accordance with veterinarian advice.
All pigs will have constant access to water. The water analysis carried out on an existing bore on Eulie showed the
water quality was suitable for pigs to drink. Water is checked daily and back up water is available from the other
bore or freshwater dams is required in an emergency.
All pigs at the grower site & gilts at the breeder site will have constant access to feed. Pregnant sows are fed once
per day and lactating sows are fed 2 times per day. Feeding will all be done using an computer controlled feed
system, this is checked daily by staff & alerts staff to break downs via alarms on their phones, when the site is
unattended.
43
Eulie Pig Farm EIS
The new pig farm will be accredited under the APIQ program, which includes a section on animal welfare.
Herd health will be maintained through strict quarantine rules, which include restricted access for visitors to the site
at permission from management, the factors considered by management include recent proximity to pigs &
abattoirs, recent travel overseas & record details of visitors to site. Farm clothing and boots are worn on site by all
people. There is no requirement for truck washes or foot baths.
Confidence in these outcomes is high.
E.17. ECONOMIC AND SOCIAL EFFECTS
E.17.a Baselines conditions
In a submission to the Productivity Commission, the Pork Council of Australia (2004) quoted “the income multiplier
for pork was the highest of all industries in the Australian economy ($1 in wages and salaries in pork production
generated $6.57 in incomes in the rest of the economy). The study also found the employment multiplier was
second only to poultry amongst agricultural industries, generating almost one extra job in the economy for each job
in the industry.”
Blantyre Farms currently employs 35 full time staff between its pig farm near Young and broad acre farms in Young
and Harden.
Current demand for sustainable and responsibly produced fresh pork is very strong. This demand is expected to
continue.
E.17.b Impact analysis
At completion the proposed pig farm will employ at least 20 full time staff, this are new positions, most of these
positions will be working directly with pigs, others will be in maintenance, management & administration. This will
have a positive flow on effect for local businesses, as staff pay for goods and services in Harden.
Local grain producers will benefit by this significant expansion of a reliable grain market.
The piggery will use a wide range of other local goods and services on an ongoing basis. This will include feed
ingredients, goods from farm supply shops, hardware, electrical, plumbing, and clothing amongst others.
The proponent anticipates capital expenditure will be approximately $12 million on development costs. Annual
operating costs for the piggery will be in the order of $7 million. Much of this will flow on to local farmers, local
retailers & service providers.
E.17.c Mitigation, management and monitoring
The proposed development will only produce positive economic and social impacts. The positive impact on Harden
should be very significant.
Confidence in these outcomes is high.

COMPILATION OF MITIGATION MEASURES
G.a
Environmental Management Outline
G.a.i
Management of construction impacts
Prior to commencement of construction within the controlled drainage areas at both sites, the perimeter earthworks
and freshwater dams (Annexure D) will be built to divert all external storm water around the sites and capture all
internal stormwater and sediment within.
Construction will occur between 7am and 6pm.
Should any item of heritage or archaeological significance be unearthed during construction, further disturbance will
cease. The item/s will be assessed by relevant heritage authorities and any necessary preservation measures
enacted.
G.a.ii Management of Operational Impacts
Daily visual inspections will occur for the covered pond, SEP’s and recycle dam on both sites. Any problems or break
downs will be rectified.
An irrigation log will be kept, including the paddock in use and period of irrigation
A calculation will be done to determine the quantity of solids removed from the effluent system, the paddocks it is
spread on & quantity if any exported from the site. This will ensure nutrient overloading does not occur. See B.1.g
for more information.
Any odour complaints will be recorded in a log and investigated immediately and followed up with the complainant.
A wind station will be installed near the sites to measure wind direction, as this is a normal requirement of the EPA
for new piggery licences.
Groundwater will be monitored six monthly from four piezometers, one of which is upstream of the proposed pig
farm sites, see Annexure L for the location of the piezometers.
Soil tests will be carried out annually on four selected monitoring points, see Annexure B for their location.
Monitoring results will be reported to the EPA through the annual license return.
G.a.iii Strategies to improve management using monitoring data
Based on annual soil tests, annual soil requirements can be determined prior to crop planting. Adjustments to
application rates can be made according to planned crop and pasture rotations. If additional nutrient is required, the
application rate can be increased or synthetic fertiliser added. If nutrient requirement is less, lower application rates
can be used or the cropping cycle can be changed to increase nutrient uptake. If deep soil nitrogen is noted, deeper
rooted crops or pastures can be grown to catch nutrients lower in the profile.
G.a.iv Training programs for operational staff
Training will be provided for all field staff involved in liquid and solid waste handling and will be made aware that any
unusual occurrence must be reported to senior management immediately.

H
JUSTIFICATION FOR THE PROPOSAL
H.a
The precautionary principle
Namely, that if there are serious threats of serious or irreversible environmental damage, lack of full scientific
certainty should not be used as a reason for postponing measures to prevent environmental degradation
The proponent has operated an environmentally sustainable pig farm near Young for a decade. There is growing
demand for the consumption of pork, the world population is rapidly & the demand for affordable, safe, cheap
protein is growing with it. This is a suitable location, both the sites and the shire, as it is not heavily populated and is
grain growing region with reasonable proximity to abattoirs.
The proponent has used solid and liquid effluent on their farm at Young to replace part of their fertiliser
requirements for cropping and pasture rotations. Effluent releases its nutrients slowly from the organic matter and
are therefore more environmentally safe applied at crop uptake rates. The proponent manages the nutrient levels
with annual agronomic soil tests and agronomic advice. The proponent is confident these practices can all easily be
put in place for the proposed development.
The proponent is confident that this proposal does not contain any threat of serious or irreversible environmental
damage.
H.b
Inter-generational equity
Namely, that the present generation should ensure that the health, diversity and productivity of the environment is
maintained or enhanced for the benefit of future generations.
47
Eulie Pig Farm EIS
It is generally understood that Australian soils are depleted of carbon and nutrient. With careful management and
fertiliser, the proponent’s lands have become a highly productive farming and grazing operation. The proponent is
confident their farming operation will enhance the health, diversity and productivity of the soil and the environment.
H.c
Conservation of biological diversity and ecological integrity
Namely, that conservation of biological diversity and ecological integrity should be a fundamental consideration.
The proponents land shave been cleared and cropped for over 50 years.
Only one small tree will be removed for this development. In excess of 500 native tress will be planted. This will
enhance biological diversity and ecological integrity.
H.d
Improved valuation and pricing of environmental resources
Namely, that environmental factors should be included in the valuation of assets and services, such as:
(1) Polluter pays, that is, those that generate pollution and waste should bear the cost of containment,
avoidance or abatement,
(2) The users of the goods and services should pay prices based on the full life cycle costs of providing goods and
services, including the use of natural resources and assets and the ultimate disposal of any waste,
(3) Environmental goal, having been established, should be pursued in the most cost effective way, by
establishing incentive structures, including market mechanisms, which enable those best placed to maximise
benefits or minimise costs to develop their own solutions and responses to environmental problems.
The proponent will bear the costs of monitoring, reporting of environmental outcomes and other compliance costs.
An intensive piggery integrated with an extensive agriculture provides for efficient recycling of nutrients and
resources that would otherwise be unused. The synergy of the combined system is a clear improvement in valuation
of resources.
