Covid-19 created an unprecedented situation for our country and Council acknowledges the enormous challenges that many business and landowners currently are facing.

About Stormwater Management Plans

Why are stormwater management plans required?

SMPs are required with the upcoming rule (C 6.2.3) in the Tairawhiti Resource Management Plan to address declining freshwater quality*.

The stormwater on site is to be managed according to that SMP.

Stormwater from industrial or trade sites can contain pollutants such as hydrocarbons; zinc and copper; animal faecal bacteria; sediment and chemicals that can affect our waterways.

To prevent this we have rules for industrial and trade activities to reduce pollution and contamination getting into stormwater and our waterways.
Read the rules in our Tairawhiti Resource Management Plan (TRMP) for the Freshwater Plan.

What needs to be included in the SMP?

The plan should include general information around the site - contact details owner and operator, site operations, hazardous substance use.

Also information around stormwater management, where is stormwater discharged to, does it get in contact with hazardous substances, is a spill management plan in place.

What are the parameters for stormwater discharge?

The Australian and New Zealand Guidelines for Fresh and Marine Water Quality** are used as limit for stormwater contamination.

The stormwater running off your property must not contain hazardous substances, agricultural chemicals or substances that are toxic to aquatic ecosystems.

** Australian and New Zealand Environment and Conservation Council (ANZECC) Guidelines for Fresh and Marine Water Quality (2000)

How do I complete an SMP without a consultant?

We encourage site owners and operators to fill out their own Stormwater Management Plans.
Here's the SMP template and guidance documents.
We're happy to help with questions regarding best management practice. However, treatment devices should be designed and installed by a qualified professionals.

Check this Site Self-Assessment before contacting a consultant.

Is there a cost?

The plan itself is free of cost but if construction or additional treatment are required these may come at a cost.
These physical upgrades do not have to be completed by August 2020, but the timeline plan for the upgrades does.

Who can assist me with Stormwater Management Plans in Gisborne?

Council provides free advice around SMPs.
However, treatment devices should be designed and installed by a qualified professional. We have an incomplete list of qualified professionals doing this type of work that may be able to provide assistance.

What if I don't know where my drains connect to?

Property information can be requested from Council, ask specifically for drainage information. Here's the information and forms  

We also recommend contacting the original drainlayer or getting a camera assessment done to check that the drains are not damaged.

Who is responsible for submitting a SMP?

Land owner and business operators are equally responsible for submitting Stormwater Management Plans for the site.

How can my business benefit from a SMP?

Businesses that don’t have a SMP detailing their current or planned (with timeline) stormwater treatment by 1 August 2020 will need to apply for a resource consent to discharge stormwater into the system.
You therefore save money by not having to apply for a discharge consents by having a SMP in place. 
Good housekeeping reduces the risk of expensive clean-ups and on-going remedial management of the contamination.
A tidy and well managed site is also more attractive to customers.

What happens if the SMP is not submitted by 1 August?

Businesses that don’t have a SMP detailing their current or planned (with timeline) stormwater treatment by 1 August 2020 will need to apply for a resource consent to discharge stormwater into the system. 
Failure to meet either of these requirements will result in compliance visits and enforcement action, if necessary.

Are the requirements likely to change?

We’re constantly aiming to improve the state of our environment and waters. There’s also a greater focus on freshwater quality, including stormwater, within New Zealand and within the government that has resulted in national standards and guidelines for improving water quality.

What is Council doing and do these requirements apply to them?

Council is also required to comply with the new standards and guidelines by submitting SMPs showing an improvement in stormwater quality discharge from the reticulated system.

Trade waste consents are required for businesses that produce commercial or industrial liquid waste (eg. food processors, hospitals, dentists, metal finishers, service stations, restaurants, cafes, freezing works).
It does not include wastewater that goes into the sewer from domestic toilets, kitchens, bathrooms or laundries.
