Activities that may make up a transmission activities project:
Relocation of poles to enable roading development
Project description: The local district council has requested Transpower to relocate three existing poles (A, B and C) on an existing 110kV transmission line, to enable the extension of an arterial road. Poles A and B are 13 metres high and pole C is 15.5 metres high. All replacement poles will be 18.15 metres high. In accordance with the mandatory requirements of NZECP 34:2001, the proposed increase in pole height is required to maintain safe clearance distances between the transmission line conductors and the ground (in this case the road).
Replacement poles A and B will be relocated 10 metres west of their existing locations. Both poles will be a further 20 metres away from any occupied buildings. Replacement pole C will be relocated 4.7 metres north of its existing location and 10 metres away from any occupied building; this is a further 1.5 metres away from any building in its current location. The project is not located in a historic heritage area or natural area.
| Main activities | Status under NES |
|---|---|
| Relocation of three existing poles with three replacement poles in a different location | These works would not be a permitted activity as the replacement poles would not meet regulation 14(3) and 14(8). The proposed works would be restricted discretionary - regulation 16. |
| Earthworks and vegetation clearance not in a natural area or historic heritage area | Any earthworks or vegetation clearance will be permitted, provided the relevant conditions in regulations 30 and regulation 33 are met. Transpower could choose to apply for a certificate of compliance for the permitted work. |
| Other potentially relevant activities | Status under NES |
| Noise from machinery | Noise from machinery is permitted by regulation 37, provided it meets the limits in NZS6803:1999 Acoustics Construction Noise. Any vibration would need to meet the vibration standard DIN 4150–3:1999. |
| Signs on support structures | Signs are permitted by regulation 23, provided conditions (2) and (3) are met. |
