Project examples

The main focus of projects undertaken by Air We Breathe has been the preparation of resource consent applications for discharges into air from a range of activities for clients ranging from privately owned New Zealand businesses to multinational industrial companies. However, we also work with local businesses to help them address specific environmental management issues and with regional councils and unitary authorities on policy development and compliance monitoring.

Plastics

   

Alto Packaging, 2017 ongoing

Assessments of environmental effects and preparation of a resource consent application for discharges into air from the manufacture of polystyrene packaging at Alto’s plant in Rosedale, Auckland.

Scope involves ambient monitoring of butane in the immediate environs of the plant, atmospheric dispersion modelling and a quantitative assessment of the effects of butane emissions from the plant, and an assessment against the relevant provisions of the Auckland Unitary Plan Operative in Part.

Combustion

   

Waitikiri Gardens, 2016

Assessment of effects of discharges into air from coal fired boilers at Waitikiri Gardens, Christchurch, for the renewal of their air discharge consent. This involved a largely qualitative assessment, based in part on previous atmospheric dispersion modelling as well as preparation of application documents, response to further information requests from the council and an assessment against the relevant provisions of the Canterbury Regional Policy Statement, the Natural Resources Regional Plan and the Proposed Canterbury Air Regional Plan.

In response to a further information request from the council, the scope was extended to include atmospheric dispersion modelling and assistance with consultation with affected parties.

Construction Materials

   

Asphalt Supply Company, 2016 ongoing

Provision of planning advice to a manufacturer of asphalt roading material regarding alternate locations for possible distribution points and alternate methods of production.

Assessment of environmental effects and preparation of a resource consent application for discharges into air from the client’s existing asphalt plant in Auckland, including a qualitative assessment of effects of emissions from the plant and an assessment against the relevant provisions of the Auckland Regional Policy Statement, Auckland Council Regional Plan: Air Land and Water and the Proposed Auckland Unitary Plan.

   

Stevenson Construction Materials, 2017

Assessment of environmental effects and preparation of a resource consent application for discharges into air from the manufacture of ready mixed concrete at Stevenson’s Penrose plant.

Scope involved a risk-based assessment of potential effects of dust emissions from the plant, based on the approach set out in the Institute of Air Quality Management’s “Guidance on the assessment of dust from demolition and construction”, and an assessment against the relevant provisions of the Auckland Unitary Plan.

Following the successful completion of this project, The Air We Breathe was also contracted to carry out workplace dust monitoring at Stevensons' three concrete batching plant across Auckland, using automatic continuous personal sampling units.

Minerals processing

   

Blue Pacific Minerals, 2015

Assessments of environmental effects and preparation of a resource consent application for discharges into air from Blue Pacific Minerals’ new zeolite processing plant and existing perlite plant in Tokoroa. Scope involved atmospheric dispersion modelling of particulate emissions, consideration of offsets for PM10 and an assessment against the relevant provisions of the Waikato Regional Policy Statement and Regional Plan.

The assessment of effects for the new zeolite plant was one of the first projects in New Zealand to consider the PM10 offset requirements under the NESAQ regulations following the 2011 amendments to the regulations. Atmospheric dispersion modelling was used to determine the proportion of PM10 discharges from the site to be offset and the extent to which reductions in PM10 discharges from Blue Pacific Minerals’ old site could be used to offset those discharges.

Animal feeds

   

Inghams, 2014

Assessment of environmental effects and preparation of a resource consent application for discharges into air from Inghams’ Hamilton feedmill. Scope involved a qualitative assessment of dust emissions from grain elevators and the feedmill and an assessment against the relevant provisions of the Waikato Regional Policy Statement and Regional Plan.

Other Activities 

Review of Technical Publication 152, Auckland Council, 2014

Technical Publication 152 (TP152) provides guidance to council officers and applicants for resource consent on the Auckland Council’s approach to the assessment of discharges to air from industry. It was released in draft form in 2002, but has not been updated since then, and has partially been superseded by other guidance.

The Air We Breathe was commissioned to review and update Chapter 6, which provides guidance on emission control technology, drawing on developments overseas and experience from consent holders in Auckland. My scope also included reviewing the overall structure of TP152, recommending sections that should be retained and updated or removed, as well as additional matters that should be addressed in a revised document.

Emissions control, Browns Bay Barbecue Restaurant, 2016

Browns Bay Barbecue Restaurant was the subject of ongoing complaints regarding emissions of smoke and fume from its kitchen extractor fans. The Air We Breathe was engaged to investigate and to advise on methods to avoid or minimise adverse effects. The solution identified was to replace the existing low vent stacks, fitted with cowls, with taller stacks discharging vertically, thus achieving adequate dispersion of emissions.

Environmental management, Intergroup, 2018 ongoing

Intergroup requested The Air We Breathe's assistance with environmental management at its existing waste treatment facility in East Tamaki, Auckland. This project commenced with assistance with varying the site's current consent for discharges into air, and expanded to include the assessment of upgrades to stormwater treatment and a complete re-write of the Environmental Management Plan, to bring the site into full compliance with all of its consents,
