Noise
From the Waimakariri District Plan: Section 23. Land Water Margins Policy 12. 1. 1. 10 – Control noise to a level that is not unreasonable, measured against the character and circumstances of the zone
From the Waimakariri District Plan: Section 23. Land Water Margins Policy 12. 1. 1. 11 – Avoid noise adversely affecting the amenity values and health and safety of people on neighbouring sites or zones
Explanation to Policy 12. 1. 1. 11 Amenity values are affected by noise in the following ways: The length of time, the level, and tonal characteristics of the noise. In most situations occasional noise is tolerated at much higher levels than continuous noise. The nature and location of nearby activities. Residential activities nearby, including camping grounds, will be sensitive to noise. In the Rural Zones, transitory noise associated with farming activities is generally accepted. Excerpts from the Waimakariri District Plan
Amenity Value “Natural or physical qualities and characteristics of an area that contribute to people’s appreciation of its pleasantness, aesthetic coherence, and cultural and recreational attributes. ” Environment Canterbury

World Metrological Organisation document, Guide to Meteorological Instruments and Methods of Observation, chapter 5, paragraph 5. 9. 2; “Wind measurements that are taken in the direct wake of tree rows, buildings or any other obstacle are of little value and contain little information about the unperturbed wind. Since wakes can easily extend downwind to 12 or 15 times the obstacle height, the requirement of 10 times obstruction heights is an absolute minimum”.
Representativeness Is this site the data was collected from representative of the proposed quarry site? Coastal vs Inland? Urban vs Rural? Is the data used accurate and representative?

Groundwater
“The risks of quarrying itself on groundwater quality are generally well managed. Rather, it is what the pits are used for after completion of quarrying that is the greatest concern. ” “Quarrying, mining and extractive activities need to be appropriately located and managed…” Canterbury Land Water Regional Plan

From the Deputy Director of Health “Water suppliers have a duty under Section 69 U of the Health Act 1956, to take reasonable steps to protect the sources of raw water for their supplies. ” From the Drinking-water Standards for New Zealand 2005, Revised 2018 “The public health safety of drinking-water is best protected if multiple barriers to contamination are in place. These barriers include: minimising the extent of contaminants in the source water that the treatment process must deal with. ”
