NZ Air has worked with applicants whom wish to develop new intensive farming operations, increase the scale or size of an existing farm, or retrofit an existing farm to meet new animal welfare standards.
Where possible NZ Air has facilitated non-notified air discharge consent applications, however if the application has been notified, NZ Air has presented expert evidence at the hearing to support the application through to granting.
NZ Air obtained a replacement air discharge consent for an expansion of one of the largest free range pig farms in New Zealand. NZ Air undertook air dispersion modelling in AERMOD to demonstrate the potential increase in off-site odour effects as a result of the farm expansion and assisted in obtaining the required affected party approvals. By working closely with the applicant and Environment Canterbury’s consent processing team, NZ Air was able to facilitate the granting of a non-notified air discharge consent.
Mainland Poultry required a land use consent to develop a new chicken egg layer farm at a greenfield site in Orini, Waikato. NZ Air undertook odour sampling at an exiting farm to develop conservative odour emission rates for the proposed farm. Then NZ Air developed prognostic meteorological data sets for the site, undertook air dispersion modelling in both AERMOD and CALPUFF, and worked with the applicant to refine the shed design to achieve lower off-site impacts.
The application was notified by the Waikato District Council and Donovan Van Kekem presented expert evidence and participated in expert caucusing at the subsequent hearing. After the decision to grant the consent was appealed by submitters, Donovan provided expert advice for Environment Court proceedings.
As a result of the Christchurch earthquakes, the University of Canterbury needed to build a new fire laboratory for its fire engineering department. The fire laboratory is used for fire engineering research and development. A very wide range of materials are/could be burnt in the experimental burns undertaken in this facility. State of the art air pollution control equipment has been installed to minimise potential off-site effects in this sensitive receiving environment. An all encompassing air discharge consent was sought during the design phase. A wide range of complex air dispersion modelling was undertaken to demonstrate compliance with ambient air quality criteria beyond the boundary of the site.
Once the consent was granted, NZ Air designed, facilitated and reported on a stack testing project to assess compliance of the built infrastructure.
