✨ Freshwater Management Amendment
NEW ZEALAND GAZETTE, No. 81 — 10 AUGUST 2017
e. in row D, after "state", insert "(without native macrophyte/seagrass cover),";
f. replace the note under the table with:
"Note: For lakes and lagoons that are intermittently open to the sea, monitoring data should be analysed separately for closed periods and open periods."
- In the "Total Phosphorus (Trophic state)" attribute table:
a. in row B, replace "nutrients" with "nutrient";
b. in row C, replace "nutrients" with "nutrient";
c. in row D, after "state", insert "(without native macrophyte/seagrass cover),";
d. under the table, insert:
"Note: For lakes and lagoons that are intermittently open to the sea, monitoring data should be analysed separately for closed periods and open periods."
- Under the "Periphyton (Trophic state)" attribute table, after the second footnote, insert:
"Note: To achieve a freshwater objective for periphyton within a freshwater management unit, regional councils must at least set appropriate instream concentrations and exceedance criteria for dissolved inorganic nitrogen (DIN) and dissolved reactive phosphorus (DRP). Where there are nutrient sensitive downstream receiving environments, criteria for nitrogen and phosphorus will also need to be set to achieve the outcomes sought for those environments.
Regional councils must use the following process, in the following order, to determine instream nitrogen and phosphorus criteria in a freshwater management unit:
a. either -
i. if the freshwater management unit supports, or could support, conspicuous periphyton, derive instream concentrations and exceedance criteria for DIN and DRP to achieve a periphyton objective for the freshwater management unit; or
ii. if the freshwater management unit does not support, and could not support, conspicuous periphyton, consider the nitrogen and phosphorus criteria (instream concentrations or instream loads) needed to achieve any other freshwater objectives;
b. if there are nutrient sensitive downstream environments, for example, a lake and/or estuary, derive relevant nitrogen and phosphorus criteria (instream concentrations or instream loads) needed to achieve the outcomes sought for those sensitive downstream environments;
c. compare all nitrogen and phosphorus criteria derived in steps a) - b) and adopt those necessary to achieve the freshwater objectives for the freshwater management unit and outcomes sought for the nutrient sensitive downstream environments."
- Under the "Nitrate (Toxicity)" Table, insert:
"Note: This attribute measures the toxic effects of nitrate, not the trophic state. Where other attributes measure trophic state, for example periphyton, freshwater objectives, limits and/or methods for those attributes will be more stringent."
- Replace the E. coli attribute table with:
| Value | Human health for recreation |
|---|---|
| Freshwater Body Type | Lakes and rivers |
| Attribute | Escherichia coli (E. coli) |
| Attribute Unit | E. coli/100 mL (number of E. coli per hundred millilitres) |
| Attribute State ¹ ² | Numeric Attribute State |
