Environmental Effects Discharge of Contaminants April 2019 1.0 INTRODUCTION Rangiora Landscape and Garden Supplies Limited, the applicant, has commissioned Bowden Environmental to act on their behalf in seeking consent to discharge contaminants to land that may enter water, as a result of composting and stockpiling of compost occurring on unsealed surface. Rangiora Landscape and Garden Supplies Limited operates a bulk material processing and storage at 114 Egans Road (Appendix 1); the site is an industrial premise, as the materials are processed for commercial purposes. The application seeks consent for decomposing organic matter, i.e. compost, at a maximum of 8,000 cubic metres of compost on site at any one time. The area within which the compositing is to occur is less than 0.5ha of the 8ha property (area shown with black outline in Appendix 1). This consent is applied for as a retrospective consent as the activity has been occurring on site since January 2006. The materials used in the compositing process include: a. Sawdust and bark; b. Mushroom (composed of Chicken Manure, Wheat Straw, Peat and Lime); and c. Pig Manure The process starts with composting material being delivered to the site. Organic material is immediately mixed with sawdust and, when required, bark. The compost typically consists of 40% sawdust mixed with approximately 60% Mushroom. This blended organic material is placed into windrows of approximately 20 metres long and 4 metres high. The base of the windrow is approximately 0.5m of sawdust which is located over top soil. The sub-surface material under the compacted gravel is composed of top soil underlain by yellow clay (refer to section 3.2.2 and Appendix 3). The windrows are turned every three to four weeks using a loader until the active compost phase is complete. The compost is then left to cure before the product is delivered to the sales yard. The applicant has over 20 years of experience with the manufacturing of compost and use this expertise for making the judgement call on the proportions of materials and timing of when turning is to occur. The applicant also holds consent CRC061256 (Appendix 2) to discharge containments to air (odour and particulate matter) from on-site storage and handling of bulk materials and landscaping supplies and the manufacture of compost material. This compost material is limited to including pig waste, chicken waste, and sawdust; and any mixture of these. The
