Plan Change 6A Archive
Proposed Plan Change 6A (Water Quality) seeks to maintain or improve water quality, through control of contaminants discharging from rural land to water. Council notified proposed Plan Change 6A (Water Quality) on 31 March 2012 and released its decisions on 20 April 2013.
The rules of the proposed plan change had legal effect from 31 March 2012.
After resolution of appeals, Plan Change 6A was made operative on 1 May 2014 and was incorporated within the Regional Plan: Water For Otago.

Frequently asked questions (about Proposed Plan Change 6A)
- When were council decisions released?
Council decisions were publicly notified on Saturday 20 April 2013.
- What is Proposed Plan Change 6A trying to achieve?
It aims to maintain good water quality and improve water quality where degraded, whilst meeting the requirements of the National Policy Statement for Freshwater Management.
- What is the plan change’s focus?
It focuses on non-point source discharges to water in rural areas i.e. contaminants coming out of drains, and from runoff and leaching.
- Will this plan change directly affect me?
Yes, if you undertake land-based activities (e.g. agriculture, forestry, subdivision) which may result in contaminants discharging into water, or if you discharge water back into water (e.g. from a dam or irrigation scheme).
- What are the key points from Plan Change 6A?
The targets for good quality water in Otago are proposed in Schedule 15. These ensure that water will be of suitable quality for a variety of purposes, such as contact recreation, fishing, stock drinking water, and mahika kai.
Prohibit objectionable discharges which have never been granted consent.
Permit discharges that meet specified limits for nitrogen, phosphorus, E.coli (Schedule 16), and sediment.
Provide clear consent options for discharges that do not meet the contaminant discharge limits.
Amend provisions on the disturbance of river and lake beds, and Regionally Significant Wetlands to:
- Discourage the use of rivers as regular stock crossings.
- Make it easier to construct crossings over water bodies.
- Reduce the risk of animal waste getting into water from crossings.
- When will these new rules affect me?
The proposed rules have legal effect from 31 March 2012. From that date, two sets of rules must be considered – those in the proposed plan change and those in the operative Water Plan.
New activities need to comply with the rules in both the operative Regional Plan: Water, and the rules in PC6A.
- Will there be a transition time?
Some land owners or managers may need time to modify their land use and water management practices to be able to comply with the proposed discharge limits.
There is an eight-year transition (to 2020) to meet the discharge limits and the nitrogen loading limit.
No transition time is provided for the prohibited discharge rules. They operate as discretionary rules until the plan change becomes operative, once any appeals are resolved.
ORC will continue to enforce the operative Water Plan, and is also able to take compliance action against any person who contravenes a proposed rule, where that rule applies.
Contact the ORC land resources manager for more information about ensuring your farm is compliant.
- What is the difference between Schedule 15 and Schedule 16?
Schedule 15 describes the targets for good quality water in Otago waterways, as required by the National Policy Statement for Freshwater Management. These are an important measure of the health of our waterways for State of the Environment monitoring and reporting on water quality in Otago generally.
Schedule 16 sets limits for contaminants being discharged into waterbodies. The proposed water quality rules relate to Schedule 16 and to sediment. Schedule 16 limits are important measurements for off-farm discharges.
- What contaminants will have a discharge limit?
Limits are proposed for sediment, E-coli, phosphorus (DRP), and nitrogen [nitrite/nitrate nitrogen (NNN) and ammoniacal nitrogen (NH4) for surface water; nitrogen loading for groundwater].
- What are discharge limits?
Discharge limits specify a maximum amount of contaminant that can be discharged into water. For surface water, they are measured as concentrations; for groundwater, nitrogen is calculated as an annual loading. The nitrogen load is calculated as the amount of nitrogen that leaches below the plant root zone using OVERSEER 6.0. For sediment, the limit is described in words rather than numbers.
Stricter surface water limits apply to catchments that are more vulnerable to the effects of contaminants. For groundwater, more stringent loads are proposed to protect sensitive groundwater and the water in Lakes Wakatipu, Wanaka and Hawea.
- What are discharge limits based on?
The proposed limits are based on the State of the Environment monitoring results compiled by ORC for surface and ground water in Otago, recognised water quality guidelines (e.g. ANZECC and others) and discharge sampling results.
- What land use activities will be most affected by the proposed discharge limits?
The effect of the proposed discharge limits on land use activities will depend on many factors, including the type of activity, what land management practices you are using, stocking rates, climate, geology, soil type, slope, and vegetation.
There is a risk of discharges breaching the limits and contaminating water from:
Intensive stocking:
Where there is a high number of stock in a small area, there is likely to be a high concentration of contaminants discharged.
Saturated soils:
Contaminants in wet soils are mobile, which creates a high risk of the contaminants making their way to waterways and into groundwater.
Soil exposure:
Activities such as harvesting forests, undertaking subdivision earthworks, ploughing soil, or using sacrificial or fallow paddocks have a high risk of sediment discharge to water.
- How do I know if the discharges from my land are within the limits?
To find out if your discharge meets the limits, take a sample of the discharge and test for the contaminants specified above. Then, review your land management practices and make any changes needed to reduce the contaminants in your discharge. Following that, test the discharge again, to see how effective your actions have been. You may have to make more than one change to clean up the discharge.
- Where and when should I sample?
The limits apply to all discharges where they are about to enter water in a river, lake or wetland, or in an open drain or water race that flows into a river, lake, or wetland.
Schedule 16 limits only apply when rivers are at or below median flow. Local flow conditions are available on the ORC water info website.
- What should I sample and how?
To check your contaminants are within discharge limits take a sample from seepages, tile drains, by-wash and swales immediately before it enters a river, lake or wetland, or an open drain or water race that flows into a river, lake, or wetland.
To have certainty about whether the limits are being met on your property, take samples from several different locations (in particular, areas where higher risk land use activities are being undertaken) at different times of the year.
A information sheet on sampling will be available soon.
- What happens if I find my discharges do not meet the limits?
Look again at your land management practices. You may have to make several changes to your operations to clean up the discharge. To assist this, you can apply for a resource consent for extra time to complete work required to ensure your property meets the discharge limits.
ORC compliance staff will follow up on breaches of prohibited activities.
- Need some more guidance?
To discuss what you need to do on your farm to comply with these rules phone ORC land resources staff on 0800 474 082.
