Agreed Facts
5The evidence in both sets of proceedings was contained almost exclusively in a comprehensive agreed statement of facts that was filed with the Court. Below is a relevant summary of that evidence.
6The company's business, operating as Robinsons Resources, concerned the receipt, storage and future removal of the disposal of waste on Lot 2822 DP 1050546 near Anna Bay within the Port Stephens Council ("the council") local government area ("the land").
7At all material times Mr Robinson was the sole director of the company. He was responsible for, and personally involved in, the day-to-day operations of the company.
8From approximately 1995 until 2008 Mr Robinson was also a councillor of the council.
9Mr Robinson's mother, Ms Sylvia Robinson, owns the land. However, at all relevant times the company was the occupier of the land and its principal place of business was situated on the land.
10The land was zoned 1(a) Rural Agricultural "a" zone under the Port Stephens Local Environment Plan 2000 ("the LEP").
11Under the LEP, development for the purposes of agriculture is exempt development. Other development is allowed but with development consent. This included "earthworks" which was defined to mean:
The addition to or removal of any solid material on any land or any other work which will alter the existing ground level or character of the surface of that land, including landfilling, drainage works and excavation of open drains.
12It is not disputed that the defendants' activities giving rise to the commission of the offences constituted "earthworks".
13The land itself is dominated by four to five acres of paddock. It contains a mobile telephone tower accessed by a construction road, both of which were constructed in or about 2003. The southern portion of the land contains a number of structures.
14The paddock has the following features:
(a) a modified stream;
(b) a swamp forest;
(c) an area containing a mixture of pasture and wetland;
(d) a culvert or drain under the constructed road; and
(e) a row of casuarinas.
15The southern portion of the land was (and still is) leased in various parcels to third parties.
16It is common ground that at no time did either of the defendants hold an environmental protection licence under s 48 of the POEOA in relation to activities at the land involving the deposit of waste. Similarly, no development consent was obtained from the council as required for the lawful disposal of the waste on the land or for the earthworks.
17On 28 March 2002, development consent was issued to a section of the land leased by the company to a third party permitting a materials recycling facility. Application for the consent was made by a company called Port Stephens Bins ("PSB"). The consent did not relate to any of the land the subject of the charges.
18After the consent was issued, PSB began operating the materials recycling facility and PSB truck drivers brought skip bins onto the leased property. The contents of the skip bins were primarily construction and demolition waste, and household waste. To the best of PSB's knowledge no asbestos contaminated waste was brought onto the leased property. Moreover, PSB took a cautious approach to identifying asbestos waste. However, it was acknowledged that on some occasions, asbestos may have unintentionally come to the PSB leased property in skip bins. Any waste identified to be potentially asbestos was taken to a waste management facility elsewhere.
19PSB processed the waste delivered to them expeditiously so that there was sufficient room to continue accepting more waste onto the PSB leased property. Tipped waste was separated and sorted into recyclable and non-recyclable materials. The non-recyclable sorted material was transported to a waste management facility off the leased property. Metals that were separated during sorting were loaded onto trucks and sold to third parties. Other recyclable materials, such as bricks and concrete, were received by the company under an agreement with PSB.
20Soon after PSB started leasing the PSB property, the company purchased a crusher. Typically an employee of PSB would move the crusher either onto the PSB leased property or onto the border of the PSB leased property on the land and feed the recyclable waste materials into the crusher. The type of waste fed into the crusher included gyprock, dirt and sand, and general building and demolition waste. Then a loader owned by the company was used to move the crushed waste onto the land. Once on the land, the crushed waste was often fed through the crusher again by Mr Robinson.
21From about 2004, the company charged PSB for receiving and processing the crushed waste. Although the amount of waste provided by PSB to the company would vary from month to month, usually the company would charge a fixed rate of about $3,000 per month to PSB for receiving and processing the crushed waste.
22Waste provided by PSB to the company was then taken to a location on the land just north of the PSB leased property to a site known as 'the mound'.
23Waste was also brought onto the land by the general public for a fee from June 2005 onwards. The waste included that brought in by trades people, contractors, lawn mowing contractors and other members of the public. The waste was brought in by a variety of vehicles, including: semi trailers, bogey tippers, small tippers, box trailers, concrete trucks, utes and cars with box trailers. The waste that was delivered was shredded, often screened and placed on the mound. Typically the type of waste included: demolition waste, concrete, gyprock, paint tins, steel, garden waste, tree stumps, household waste and plastic, including plastic bags and bottles. Some of the waste contained asbestos. The defendants, in effect, operated a form of tip on the land.
24Some of the waste received onto the land was not processed and was placed directly onto the mound. Other waste was processed by crushing and/or screening. The screening process produced three piles of waste. However, having screened the waste into separate piles, the defendants moved the screened waste onto the mound or onto other areas on the land known as 'raised areas', thereby intermingling the screened waste.
25On 1 December 2004, Mr Robinson on behalf of the company, authored a letter under the Robinsons Resources letterhead to the Environment Protection Authority ("EPA"). The letter referred to the fact that Robinsons Resources was developing a resource recovery facility at the land in alliance with the existing PSB waste transfer station. A description of the operation included the operation of a shredder machine and secondary processing of the waste by screening and crushing. Comment from the EPA was sought in relation to the operation, which would accompany an integrated development application to the council. The letter concluded by stating that "as the Anna Bay operations will not be exceeding 30,000 tonnes per year there is no requirement for a licence at this site." The significance of this letter to the defendants' state of mind at the time of the commission of the offences is explained below.
26On 22 June 2007, an inspection of the land took place with officers of the council. The council officers observed the raised areas, which were made out of uncompacted building and demolition waste. The raised areas were parallel to the waterway and was being used as an access road. The raised areas were approximately 335 m long, about 1.2 m high and about 6 m wide, with batters down to natural ground level. The raised areas appeared to be freshly formed and had two distinct layers. The base layer was composed of shredded building waste such as wood, brick, tile, concrete, plastic, metal, paint cans and plastic drums. The top layer was a soil like material containing small shredded pieces of waste such as plastic and wood. Pieces of the waste from the road had fallen into the waterway and were floating on its surface. Building waste material, such as bits of tile, brick and concrete, was also submerged in the water of the adjacent waterway. The council officers took photos depicting their observations.
27The council officers proceeded further onto the land. In addition to the raised areas, they observed the mound, together with a materials sorting area adjacent to the mound. The mound is a large hill of waste about 80 m long, 10 m wide at the base, 5 m wide across the apex and with batters 5-8 m in length and approximately 4-6 m high. The creation of the mound does not form part of the charges.
28Other smaller stockpiles of material adjoin the mound, including a stockpile of soil type material. All other stockpiles appeared to be of a general building waste material that had been shredded or had been stockpiled in various stages of shredding. There was a stockpile of large pieces of concrete up to 1-2 m in length.
29During the inspection, council officers had a conversation with Mr Robinson who explained the sorting process of the building materials. Mr Robinson told the council officers that the soil material resulting from the sorting and shredding process had value because it could be used for landscaping. Mr Robinson also indicated that he wanted to use the building material for the construction of roads and landscape mounds elsewhere.
30The council officers directed Mr Robinson not to undertake any more work on the raised areas and left the land.
31Following the inspection of the land by the council officers, the council wrote to Mr Robinson requesting him to immediately put into place erosion and sediment controls to protect the surrounding area.
32An officer from the Department of Environment, Climate Change and Water ("DECCW") inspected the land on 6 July 2007. The DECCW officer divided the raised areas into various discrete areas (areas A-G). Area A comprised building and demolition waste, including pieces of tile, glass, plastics, timber, metals, labels, paper, fibreboard, containers, plastic piping and what appeared to be asbestos. The officer observed similar waste floating within the waterway close to one of the sections adjacent to area A.
33The officer also took a number of samples of waste from the mound suspected to be asbestos. Due to the expense of analysing numerous samples for asbestos, only a small number of items of waste that were suspected to be asbestos were collected. In four out of the six areas sampled asbestos was detected.
34On 31 July 2007, a further inspection of the land by DECCW officers occurred. The DECCW officers observed that the condition of the land was similar to that which he had observed during the inspection on 6 July 2007. The only change was the installation of the small sediment fence pursuant to the earlier council request. However, the officers did not consider the fence effective, as it was not long enough and did not prevent waste from falling or blowing into the waterway. The DECCW officers observed that waste had spilled over the top of the fence and into the waterway.
35During this inspection, one of the DECCW officers noticed waste that she suspected to be asbestos every 10 to 20 steps on various sections of the raised areas. A number of samples were taken to determine whether asbestos material was present. Again, due to the expense of analysing numerous samples for asbestos, only a small number of items of waste that were suspected to be asbestos in each area were collected for sampling. With the exception of area F, all other areas in which samples were taken (areas A-G) returned a positive result for asbestos.
36DECCW officers measured each of the separate areas of the raised areas on the land. At its highest the raised areas were 1.2 m. At their widest they measured 8.5 m. The approximate combined length of each of the areas of the raised areas was 548 m.
37On 7 August 2007, Mr Robinson was served with a draft clean up notice. The notice required further sediment fencing and that the waste on the land not be moved. Mr Robinson requested that the notice give further time for compliance. On 14 August 2007, a final clean up notice was issued.
38On 22 November 2007, the land was surveyed by registered surveyors. The results indicated that 2,230 m 3 of waste was contained in the raised areas.
39During the course of interviews with the investigating authorities, Mr Robinson stated his reasons for constructing the raised areas (these are discussed in greater detail below). He also disclosed that the raised areas were constructed by him operating a case loader and its construction commenced in January 2007.
40The waste materials that were fed into the crusher and, ultimately, deposited on the raised areas were sourced from both PSB and the public.
41The waste deposited on and in the raised areas was deposited in an environmentally sensitive area.
