Westpork are seeking to have the piggery licenced for 28,368 Standard Pig Units (SPU) under Schedule 1 of the Environmental Protection Regulations 1987, prescribed as Category 2: Intensive Piggery: premises on which pigs are fed, watered and housed in pens. Significant upgrades have been implemented at the site since Westpork took ownership of the operation under Works Approval W6268/2019/1. 1.2 PURPOSE The purpose of this licence application is to request approval to operate an intensive piggery at the premises, as required under Section 57 of the Environmental Protection Act 1986. The premise is prescribed under Category 2 – intensive piggery: premises on which pigs are fed, watered and housed in pens. 1.3 LICENSEE AND OPERATOR OF PREMISES The licensee and operator is Westpork Pty Ltd.

Aurora Environmental WPK2020-014-LIC_002_CH_V1 Page 8 of 21 19 June 2020 Westpork Kojonup – Licence Application 2 PREMISES DESCRIPTION 2.1 PIGGERY TYPE There are five stages in pig production: 1. Breeding. 2. Gestating or dry sows. 3. Farrowing. 4. Weaning. 5. Growing / finishing. Intensive piggeries can include one or more of the stages listed above and generally fall into one of the following categories: • Farrow-to-finish – includes the breeder, weaner and grower / finisher stages. The pigs born at the site are reared until sale age (20-26 weeks of age). • Breeder – includes breeding stock, with the offspring being removed from the piggery at, or just after, the weaning phase. • Weaner – includes only weaner pigs, aged from 3 weeks to 10 weeks of age. • Grower/finisher – includes grower pigs (aged from 10 weeks to 16 weeks of age) and finisher (from 16 weeks up to 26 weeks of age). Westpork propose to operate the Kojonup piggery as a grower facility, accepting weaners (3-10 weeks old) from offsite and growing the pigs onsite until finishing stage (approximately 23.5 weeks). The pigs will be housed in a combination of eco-shelters and conventional sheds. 2.2 STOCK NUMBERS In determining the production or design capacity of intensive piggeries, DWER considers the maximum number of pigs within the premises at any one time, determined using SPU (DWER, 2018). Westpork propose to accept approximately 1,400 weaners per week (average of 72,000 annually) and will house on average 17,870 pigs in eco-shelters and 7,658 pigs in conventional sheds at any one time. The total maximum number of pigs at any given time will not exceed 26,024 animals (29,709 SPU). Table A lists the average stock numbers and SPU housed in conventional sheds and eco-shelters. All of the weaners will be housed in the sheds along with 50% of the porkers and 30% of the growers and finishers. This number may fluctuate but is unlikely to exceed the maximum stock numbers listed in Table A.
