6.1.16 Implementation Methods - Mineral Extraction, Size Reduction, Screening and Storage

6.1.16.1 Permitted Activity Rule – Mineral Extraction, Size Reduction, Screening and Storage

The discharge of contaminants to air from any mineral extraction, processing and storage operation is a permitted activity subject to the following conditions:

  1. Where the operation occurs within 1000 metres of a property boundary and there is a discharge of particulate matter beyond the property boundary the following measures shall be implemented:
    1. the use of water sprays to suppress dust from crushing and screening plants, access ways, haul roads, stockpiles, load out areas and access roads
    2. the sealing and maintenance of the access road, when it is within 150 metres of a neighbouring residential dwelling.
  2. As specified in Section 6.1.8 a) to e) of this Plan.
  3. Within seven working days of commencing works at a new site, the operator of the new quarrying site shall provide the Waikato Regional Council with written notification of the location of the site.
  4. Should an emission of particulate matter occur that causes adverse effects of an objectionable nature beyond the property boundary as determined in accordance with the decision making guidelines set out in Section 6.4.2.2, the quarry operator shall provide a written report to the Waikato Regional Council within five days of the incident occurring, which specifies:
    1. the cause or likely cause of the event and any factors that influenced its severity
    2. the nature and timing of any measures implemented by the quarry operator to avoid, remedy, or mitigate any adverse effects
    3. the steps to be taken to prevent recurrence of similar events.
  5. There shall be no discharges of hazardous substances into the air,

Advisory Notes:

  • A resource consent will be required for the discharge of particulate matter into air from a quarrying operation or associated ancillary activities, if it is deemed by an officer of the Waikato Regional Council, using the decision-making guidelines given in Section 6.4.2, that all reasonable steps are not being taken to keep dust emissions to a practicable minimum, and the discharge of particulate matter from the site or ancillary activities is having an objectionable or offensive effect beyond the boundary of the site.
  • The operation of an overburden disposal area is considered to be an ancillary activity. Consequently, when stripping and placing overburden for mineral extraction purposes, the conditions in Rule 6.1.16.1 apply. Overburden disposal areas also constitute a discharge of contaminants into or onto land and are addressed in Rule 5.2.5.1.
  • Other Rules that should be considered alongside Rule 6.1.16.1 are Rules 6.1.9.1 part 6 and 6.1.9.2.
  • If any of these conditions are not complied with then the activity is a discretionary activity in accordance with Rule 6.1.9.2.
  • Land use consents may also be required in district plans. These will address issues such as amenity effects, traffic and noise. The thresholds at which resource consents are required vary within each territorial authority area. In some areas the activity may be prohibited under the relevant district plan.

Explanation and Principal Reasons for Adopting Method 6.1.16.1
Rule 6.1.16.1 provides for the discharge of contaminants to air associated with the extraction, size reduction, screening and storage of minerals (including coal, coke, carbon and sand). The rule recognises that the potential for this activity to have adverse effects is generally determined by site management practices and distance to receptors (including vulnerable flora and fauna).

The conditions listed in a) to e) of this Rule constitute a BPO in accordance with Policy 4 of this Chapter, and these conditions must be complied with for the activity to be considered a permitted activity. These conditions address the adverse effects from discharges to air from this activity. Compliance with these conditions will be assessed using the guidelines stipulated in Section 6.4.2.2. If the activity does not meet these conditions the activity becomes a discretionary activity under Rule 6.1.9.2.
