The relevant facts
4 ML1 was granted on or about 8 January 1948 and was subsequently renewed from time to time. ML2 was granted on or about 8 March 1972 and it has also been renewed from time to time, most recently on 2 March 2000. It will expire on 8 March 2020. On 20 December 2002 both leases were transferred to the second respondent. Both leases are adjoining and are apparently worked concurrently.
5 The second respondent acquired the two mining leases from Nowra Brickworks (NSW) Pty Ltd because of the strong shale reserves. As I understand it, the first respondent is an associated company of the second respondent and is the entity which is actually carrying out the mining on both mining leases. The number of the first respondent's employees fluctuates between 18 and 21. The majority of those employees are apprentices who are also undertaking formal study through the TAFE organisation. It also has a supplier list of mechanics, equipment hire, and general service organisations totalling 117 companies, and it has a contractor list of 227. Mining operations are conducted on ML1 and ML2 on a daily basis simultaneously, and there are units operating on both faces simultaneously. According to Mr J B Green, who is the sole director of both respondents, the operations of the respondents are vital for ongoing projects in the Nowra area and these projects, whether road construction or building projects, provide significant employment in the area.
6 The respondents have, since my previous judgment, engaged City Plan Services Pty Ltd to prepare a development application. Although my judgment was delivered on 5 July 2006, it was not until 8 September 2006 that City Plan Services was engaged. According to Mr A Smith, the planning director of City Plan Services, the recent departure of key planning staff has meant that little work has been done to prepare a development application. Indeed, Mr Smith has not yet inspected the site. And since the development is classified as a designated development, requiring the preparation of an environmental impact statement, it is self-evident that it will be some time before a development application will be ready to be made.
7 Mr Green states that mining operations can continue on ML1 and use can be made of current stockpiles on both ML1 and ML2 (which will run out in January 2007). However, if extraction of material were to be restricted to ML1, it will involve disruption to the overall operations because of the need to re-arrange the infrastructure, such as the need to relocate the stationary plant and the concrete stockpiles, to remove and re-establish the haul roads and remove areas that have been rehabilitated. All this would, of course, involve considerable additional expenditure. For example, the cost of moving plant and concrete stockpiles is said to be about $150,000. Significant work would be needed to move the current location of the tailing pond and wetland area, involving significant environmental degradation.
8 If, however, mining operations are allowed to continue on ML2, it will not be necessary for any of this to occur.
The parties' submissions
9 Mr J A Ayling SC, appearing for the applicants, relies upon the public interest in the orderly development and use of land. Mr Ayling submits that unless this is done: (i) equal justice may not be secured; (ii) damage to the environment may be done without proper environmental controls; (iii) although there are conditions attached to the mining lease they relate to mining operations on the site and not to external environmental impacts such as traffic; (iv) the breach of the EP&A Act is not merely technical; and (v) Mr Green's evidence shows that it is possible for the respondents to meet their contractual obligations from stockpiled material and from working within ML1. Mr Ayling further submits that although the applicants are commercial competitors of the respondents, that fact is not sufficient to deny them the relief that they seek (referring to GPT Re Ltd v Wollongong City Council (No. 2) [2006] NSWLEC 401).
10 Mr I J Hemmings, appearing for the respondents, relies upon the following submissions: (i) the present operations are subject to environmental controls by the conditions of the mining lease and the conditions of the environmental protection licence issued by the Environment Protection Authority; (ii) as to the former, the conditions require the approval of a mining operations plan and annual environmental reports, and rehabilitation of the area on completion of operations; (iii) a mine safety management plan is also in place; (iv) the respondents purchased a business in 2003 that had been in operation for many years and they had no reason to believe that any part of the operations were unlawful; (v) since my judgment of 5 July 2006 the respondents have cooperated with the council and have accepted the need for a development application and they will abide by any decision on the development application; (vi) there is no evidence of environmental harm, nor harm to the general amenity of the surrounding area; and (vii) the respondents would suffer hardship, noted in par [7] above, if they were to be restrained from operating within ML2.
