Evidence
9The Council filed a statement of facts and bundle of documents which was supplemented by two affidavits the Defendant agreed could be read only for the purposes of the motion being considered. The Defendant tendered Council policy documents referred to in the affidavit of Mr Graeme Bailey dated 5 March 2013 including a letter dated 27 July 2012 from the Defendant to Mr Bailey seeking particulars about the second clean-up notice and rainfall data for the surrounding area for May, June and July 2012. Mr Bailey is a compliance officer employed by the Council. A bundle of documents referred to in the second clean-up notice was tendered by the Defendant which included the NSW Rural Fire Service Planning for Bushfire Protection 2001 Chapter 4, the Council's Vehicular Access Policy and three manuals including the Northern Rivers Local Government Development and Design Manual, section D7 Erosion and Control and Stormwater Management, Northern Rivers Local Government Construction Manual sections C211 and C220 and Department of Water and Energy Guidelines for Controlled Activities: Watercourse Crossings and In Stream Works.
10The affidavit of Graeme Bailey was read. Mr Bailey states that he attended the land on 22 May 2012 following a complaint received by the Council regarding alleged unlawful road construction works. From his initial research Mr Bailey determined the reported road works may be being undertaken without the required consents or other than in compliance with a consent. Mr Bailey observed that an extensive amount of excavation works were being conducted on the side of a steep escarpment. He noticed that no sediment and erosion controls had been installed at any location.
11On the morning of 23 May 2012 Mr Bailey had a telephone conversation with Mr Ihalainen to the effect that Mr Bailey was concerned that there were no sediment and erosion controls which should be in place at all times whether it was raining or not. Mr Bailey requested Mr Ihalainen to stop the construction works until the sediment and erosion controls were installed. Mr Ihalainen agreed and said he would put the controls in place by the following afternoon. Mr Bailey then said that Council would be sending Mr Ihalainen some correspondence in relation to this matter and would be out to ensure the controls are constructed.
12Mr Bailey attended the land on 24 May 2012 when he said to Mr Ihalainen that he was there to inspect the installation of the erosion and sediment controls and to give him a clean-up notice. At this time Mr Bailey was concerned whether the track satisfied the standards required by s 4.3.3 of the NSW Rural Fire Services Planning for Bushfire Protection 2001, whether it complied with the conditions of development consent to DA 2005/842, whether the sediment and erosion control fences being installed conformed with section D7 of the Northern Rivers Local Government Development and Design Manual, and the Council's guidelines for the control of soil erosion and sediment on building and development sites. Mr Bailey considered that the sediment and erosion control measures he observed being installed would not be effective long term solutions.
13Between 28 May 2012 and 1 June 2012 a number of emails passed between Mr Bailey and Mr Ihalainen including a sediment and erosion control plan prepared by Orchard Floor Protection Service dated 31 May 2012. Mr Bailey consulted with Council's development engineers, including Mr Lacey, and came to the view that the sediment and control plan was inadequate to address the requirements of the first clean-up notice. This was communicated to Mr Ihalainen on 1 June 2012 with a request for more detailed sediment and erosion control works.
14On 4 June 2012 Council received four plans from Mr Ihalainen. Mr Bailey believed these plans did not address the necessary issues on large sections of track. Mr Bailey sent Mr Ihalainen a "show cause" letter dated 7 June 2012. On 12 June 2012 Mr Ihalainen responded to this letter. Council did not receive any further information to show that the unacceptable elements of the sediment and erosion control plan had been addressed. On 21 June 2012 Council received an email from Mr Kennedy, a principal of Tricend Design and Engineering, attaching a plan which in Mr Bailey's opinion was substandard. Mr Bailey believes that no serious attempt was made to address the requirements of the first clean-up notice.
15On 27 June 2012 Mr Bailey and Mr Lacey attended the land to conduct a planned meeting with Mr Kennedy whilst it was raining. Mr Ihalainen had emailed Mr Bailey saying that because it was raining he was attempting to reschedule. Mr Bailey did not receive this email. Mr Bailey decided to conduct an inspection in any case to determine the effectiveness of sediment and control measures put in place. Mr Bailey observed that the installed controls were not operating in a manner that captured the sediment transported in the stormwater and protected the environment. Mr Bailey took water samples.
16After this inspection Mr Bailey, Mr Lacey, Mr Kennedy and Mr Ihalainen conducted another inspection on 6 July 2012. Mr Bailey recalled that Mr Lacey advised Mr Kennedy and Mr Ihalainen what issues should be addressed and suggested solutions. On Mr Bailey's return to the office he drafted a plan of the land and detailed the issues raised at the on-site meeting. This plan was reviewed by Mr Lacey and emailed to Mr Kennedy and Mr Ihalainen on 9 July 2012.
17At a later meeting with Council's development engineers (including Mr Lacey), Environmental Health Coordinator and the Manager of Development and Compliance it was concluded that the sediment and erosion control plans supplied to Council had not satisfactorily addressed the requirements of the first clean-up notice. It was decided that a second clean-up notice should be issued in an attempt to compel compliance with Council's requirements. This was issued on 9 July 2012. Amongst the factors that were considered by Mr Bailey in deciding to issue the second clean-up notice were the occurrence of a pollution event comprising the entry of sediment laden water into the watercourse located on the land because of inadequate installation and poor maintenance practices, and the potential for further pollution events to occur.
18A record of rainfall in the surrounding area from the Bureau of Meteorology for the months of May, June and July was exhibited to Mr Bailey's affidavit.
19The affidavit of Mr Lacey, development engineer employed by the Council, dated 6 March 2013 was also read. Mr Lacey stated that on 27 June 2012 he and Mr Bailey attended the land when it was raining quite heavily. He observed that the fence and gate access at the entrance to the land looked newly constructed. He also observed that the track was incomplete and that sections of the track required substantial cut and fill to form the track, being cut and fill which he estimated to be over 1.2 m high and batters with a slope greater than 45 degrees.
20Following the inspection of 27 June 2012 and reading the development consent granted by the Council for DA 2005/842 Mr Lacey considered whether development consent condition 9 requiring sediment and erosion controls to be implemented had been complied with. Mr Lacey was also aware that Planning for Bushfire Protection 2001 also regulates soil and erosion management associated with fire access tracks such as the partially completed track he had observed on the land. That track is identified in the plan annexed to the development consent for DA 2005/842 and described as "proposed secondary driveway access" depicted by a black dotted line.
21Following Mr Lacey's observations on 27 June 2012 of the construction of the access track he undertook an assessment of the access track against the requirements of Planning for Bushfire Protection 2001, Council's Development Control Plan No. 1 - Residential Development, Council's Guidelines for the Control of Soil Erosion and Sedimentation on Building and Development Sites, Council's Guidelines for Erosion and Sediment Control on Building Sites and the Northern Rivers Local Government Design and Construction Manual.
22Mr Lacey is not aware, following his review of the Council's file concerning DA 2005/842, of any engineered road design being carried out by a practising civil or structural engineer in respect of the access track. Mr Lacey had only seen a concept design or layout for the access track being the plan for consent DA 2005/842 in his review of the files and documents held by Council depicting any specifications of the access track.
23Mr Lacey's opinion is that at the time of the 27 June 2012 inspection, the erosion and sediment controls that had been installed were not being maintained to prevent soil erosion and the transportation of sediment from the land into the natural watercourse present on the land. Excessive cut and fill (batters) had been carried out on the land, an example of which he estimated to be over 1.2 m and a batter of greater than 45 degrees.
24Mr Lacey states that there are various standards for establishing suitable slope for batters. Excess fill for road construction would require consideration in the context of suitability of the material and compaction in order to comply with s 4.3.3 of Planning for Bushfire Protection 2001 and in particular the requirement to have appropriate drainage and erosion controls. The access track needs to be constructed to a standard that would last and serve the purpose for which it was being constructed because it must be maintained in a serviceable condition by the landowner and must be trafficable under all weather conditions. The material used for the road construction appeared to be sourced from the site as Mr Lacey did not observe any stockpiling of imported quality road base material and he observed evidence of quarrying at the site by the presence of large areas of cut in the surface of the land. A lack of quality road base or a reliance on site-sourced material carries a high risk of being inadequate for a fully loaded fire fighting vehicle or of being unsuitable for all water access as required under s 4.3.3. To confirm whether the track could handle the required loading, a suitable engineering design would be needed which Mr Lacey had not sighted on the Council file. In Mr Lacey's opinion, if the road base material had been sourced from a professional supplier, the likelihood of the surface being slippery and muddy, such as observed on the site view of 27 June 2012, would be much lower.
25During the 27 June 2012 inspection, Mr Lacey observed that stormwater drainage along the access track appeared to have a general lack of adequately sized and formed drainage channels along the roadside. There was insufficient depth for open drains and there were open drains with slopes in excess of 12 per cent without a form of suitable lining, which is required to prevent soil erosion and sediment flow into the watercourse.
26Based on Mr Lacey's observations on 27 June 2012, the access track construction did not comply with the requirements of s 4.3.3 of Planning for Bushfire Protection 2001, for access with respect to bend radius. Section 4.3.3 requires that access curves have a minimum inner radius of 6 m. Based on Mr Lacey's observations and rough estimates, the two hairpin bends each had an inner radius of less than 6 m.
27Section 4.3.3 of Planning for Bushfire Protection 2001 provides a maximum grade of 15 degrees. Mr Lacey observed that a number of sections of the track were above 10 degrees and close to the maximum grade. Mr Lacey considered that although strictly speaking the access track complied with the maximum gradient controls, the manner in which the track had been constructed made the gradients more likely to contribute to sediment laden water entering the watercourse. In his experience steep roads with gradients above 10 degrees which have a dirt and low quality road base are less stable and therefore more likely to cause water pollution.
28During the 27 June 2012 inspection Mr Lacey observed bank instability on a sharp bend with an inner radius of less than 6 m and a small land slop on an embankment. Eroded soil was filling and overloading the silt fencing that was in place as a result of the uncontrolled water flowing over the construction site. As a result, the silt fencing had collapsed because of the pressure put against it by the soil, debris and rock which had come loose from the road surface.
29Following the 27 June 2012 inspection, a further site meeting was arranged to take place on 6 July 2012 with Mr Kennedy. On 6 July 2012 Mr Bailey, Mr Kennedy, Mr Ihalainen and Mr Lacey attended the land. They stopped at various locations along the access track and had conversations at those stops as follows:
(a)Identifying locations where sediment and erosion control measures were ineffective, where Mr Lacey said that the silt fencing needed to be relocated to more suitable positions, observing the stormwater flows when it is raining and other locations where water flow has been going to indicate areas that need protection. Mr Kennedy said "yes" to this.
(b)Identifying locations where further and/or additional sediment and erosion controls were required. Mr Lacey pointed out the long sections or length of drainage channel where there was a reasonable slope with no additional measures to control the water flow. Mr Lacey said that the slope and the need for riprap or rock lining of the drain and measures to slow the water velocity need to be considered suggesting the placement of hay bales or multiple sections of silt fencing across the drain to slow and catch sediment. Mr Kennedy said "yes" to this.
(c)Discussion regarding the timing and manner in which the culvert and creek crossing was to be constructed. Mr Lacey asked whether Mr Kennedy could advise when he could respond to the Council concerning when and how he plans to construct the culvert shown on the plan. The plan needs to describe how Mr Kennedy is going to manage the water flow during the work and what measures he proposed to manage the disturbed soil during the excavation. Mr Kennedy said "yes" to this.
(d)Discussion regarding the sizing of piped culverts and providing some approximate calculation to prove the pipe size election was adequate based on the area of each catchment discharging through each pipe. Mr Lacey asked Mr Kennedy whether he knew who had sized the concrete pipes being used for the crossings and culverts to which Mr Kennedy replied "no." Mr Lacey said that he noticed that all the pipe crossings were the same size and that he would need to use the volumes from each catchment and confirm that the pipe sizing was adequate to which Mr Kennedy replied "yes, I understand I will do that."
(e)Discussion regarding stormwater energy dissipaters on the exist [sic] side of each piped culvert which took place at each section where there was a proposed pipe crossing such as near the landslip. Mr Lacey said to Mr Kennedy that when he submits a plan he would need to show detail of his piped outlets, how he proposed to construct the outlet apron to limit soil and show the spread of flow rather than simply providing a short length of hard surface. Mr Kennedy said "yes, I can do that" in response.
(f)Discussions regarding general compliance of the track with the requirements for access by the Rural Fire Service, other emergency services and reference to Planning for Bushfire Protection 2001. Mr Lacey said that Mr Kennedy needs to comply with the access track requirements for the Rural Fire Service and that Mr Lacey believed the bends in the track did not have proper turning circles. Mr Lacey said Mr Kennedy needed to do an overall assessment on compliance with the standard including nominating or constructing passing bays. Mr Kennedy said "yes, I will do that" in response.
30Mr Bailey then said to Mr Kennedy and Mr Ihalainen words to the effect of "I will put down our requirements in a letter to confirm our expectations." Mr Bailey and Mr Lacey then left the land. The second clean-up notice was served on 9 July 2012.
