(2) Unless the context requires another meaning, any term used but not defined in these regulations, but defined in the Act, has the same meaning as in the Act.

4 Meaning of meets the health quality criteria

(1) In these regulations, in relation to drinking water, meets the health quality criteria means drinking water that—
- (a) is tested for determinands—

Water and discharge permits in respect of activities with potential to affect certain drinking-water supplies

6 Type of activity to which regulations 7 and 8 apply

Regulations 7 and 8 only apply to an activity that has the potential to affect a registered drinking-water supply that provides no fewer than 501 people with drinking water for not less than 60 days each calendar year.

7 Granting of water permit or discharge permit upstream of abstraction point where drinking water meets health quality criteria

A regional council must not grant a water permit or discharge permit for an activity that will occur upstream of an abstraction point where the drinking water concerned meets the health quality criteria if the activity is likely to—
- (a) introduce or increase the concentration of any determinands in the drinking water, so that, after existing treatment, it no longer meets the health quality criteria; or
- (b) introduce or increase the concentration of any aesthetic determinands in the drinking water so that, after existing treatment, it contains aesthetic determinands at values exceeding the guideline values.

8 Granting of water permit or discharge permit upstream of abstraction point where drinking water not tested or does not meet health quality criteria

(1) A regional council must not grant a water permit or discharge permit for an activity that will occur upstream of an abstraction point where the drinking water concerned is not tested in accordance with the compliance monitoring procedures in the Drinking-water Standard if the activity is likely to—

- (b) introduce or increase the concentration of any aesthetic determinands in the drinking water so that, after existing treatment, it contains aesthetic determinands at values exceeding the guideline values.
(2) A regional council must not grant a water permit or discharge permit for an activity that will occur upstream of an abstraction point where the drinking water concerned does not meet the health quality criteria if the activity is likely to—
- (a) increase, by more than a minor amount, the concentration of any determinands in the water at the abstraction point that in the drinking water already exceed the maximum acceptable values for more than the allowable number of times as set out in table A1.3 in Appendix 1 of the Drinking-water Standard; or
- (b) increase the concentration of any determinands in the water at the abstraction point that in the drinking water do not exceed the maximum acceptable values for more than the allowable number of times as set out in table A1.3 in Appendix 1 of the Drinking-water Standard to the extent that the drinking water, after existing treatment, exceeds the maximum acceptable values for more than the allowable number of times as set out in the table in relation to those determinands; or
- (c) introduce or increase the concentration of any aesthetic determinands in the drinking water so that, after existing treatment, it contains aesthetic determinands at values exceeding the guideline values.

Permitted activity rules in respect of activities with potential to affect certain drinking-water supplies

9 Type of activity to which regulation 10 applies

Regulation 10 only applies to an activity that has the potential to affect a registered drinking-water supply that provides no fewer than 501 people with drinking water for not less than 60 days each calendar year.

10 Limitations on permitted activity rules for activities upstream of abstraction points

(1) A regional council must not include a rule or amend a rule in its regional plan to allow a permitted activity, under section 9, 13, 14, or 15 of the Act, upstream of an abstraction point where the drinking water concerned meets the health quality criteria unless satisfied that the activity is not likely to—
- (a) introduce or increase the concentration of any determinands in the drinking water so that, after existing treatment, it no longer meets the health quality criteria; or
- (b) introduce or increase the concentration of any aesthetic determinands in the drinking water so that, after existing treatment, it contains aesthetic determinands at values exceeding the guideline values.
(2) A regional council must not include a rule or amend a rule in its regional plan to allow a permitted activity, under section 9, 13, 14, or 15 of the Act, upstream of an abstraction point where the drinking water concerned is not tested in accordance with the compliance monitoring procedures in the Drinking-water Standard unless satisfied that the activity is not likely to—
- (a) increase the concentration of any determinands in the water at the abstraction point by more than a minor amount; or
- (b) introduce or increase the concentration of any aesthetic determinands in the drinking water, so that, after existing treatment, it contains aesthetic determinands at values exceeding the guideline values.
(3) A regional council must not include a rule or amend a rule in its regional plan to allow a permitted activity, under section 9, 13, 14, or 15 of the Act, upstream of an abstraction point where the drinking water concerned does not meet the health quality criteria unless satisfied that the activity is not likely to—
- (a) increase, by more than a minor amount, the concentration of any determinands in the water at the abstraction point that in the drinking water already exceed the maximum acceptable values for more than the allowable number of times as set out in table A1.3 in Appendix 1 of the Drinking-water Standard; or
- (b) increase the concentration of any determinands in the water at the abstraction point that in the drinking water do not exceed the maximum acceptable values for more than the allowable number of times as set out in table A1.3 in Appendix 1 of the Drinking-water Standard to the extent that the drinking water, after existing treatment, exceeds the maximum acceptable values for more than the allowable number of times as set out in the table in relation to those determinands; or

Resource consents in respect of activities with potential to affect certain drinking-water supplies

11 Type of activity to which regulation 12 applies

Regulation 12 only applies to an activity that has the potential to affect a registered drinking-water supply that provides no fewer than 25 people with drinking water for not less than 60 days each calendar year.

12 Condition on resource consent if activity may significantly adversely affect registered drinking-water supply

(1) When considering a resource consent application, a consent authority must consider whether the activity to which the application relates may—
- (a) itself lead to an event occurring (for example, the spillage of chemicals) that may have a significant adverse effect on the quality of the water at any abstraction point; or
- (b) as a consequence of an event (for example, an unusually heavy rainfall) have a significant adverse effect on the quality of the water at any abstraction point.
(2) If the consent authority considers that the circumstances in subclause (1) apply, and it grants the application, it must impose a condition on the consent.

(3) The condition must require the consent holder to notify, as soon as reasonably practicable, the registered drinking-water supply operators concerned and the consent authority, if an event of the type described in subclause (1) occurs that may have a significant adverse effect on the quality of the water at the abstraction point.

Consent authority requirements may be more stringent than regulation requirements

13 Consent authority may impose requirements more stringent than requirements in these regulations

A consent authority may do either or both of the following:
- (a) make or amend rules in a regional plan that are more stringent than the requirements of these regulations:
- (b) impose conditions on resource consents that are more stringent than the requirements of these regulations.

Transitional provisions

A regional council is not required to amend an existing rule in a plan that does not comply with regulation 10 until the earlier of the following:
- (a) a scheduled review of the plan; or
- (b) a plan change or variation that relates to the existing rule is introduced.

15 Proposed plan not affected by these regulations if submissions already closed

(1) A regional council is not required to amend a rule in a proposed plan that does not comply with regulation 10 if the closing date for submissions on the plan has passed before the commencement of these regulations.

Explanatory note

This note is not part of the regulations, but is intended to indicate their general effect.

These regulations are the Resource Management (National Environmental Standards for Sources of Human Drinking Water) Regulations 2007. The regulations are made under the Resource Management Act 1991 and come into force 6 months after the date of their notification in the Gazette.

The purpose of the regulations is to reduce the risk of contamination of drinking-water sources by requiring regional councils to consider the effects of certain activities on drinking-water sources when—

granting water permits or discharge permits (regulations 7 and 8); and
including or amending rules in a regional plan in relation to permitted activities (regulation 10).

The regulations also require regional councils and territorial authorities to impose a notification requirement on certain resource consents in the circumstances where an event occurs that may have a significant adverse effect on a drinking-water source (regulation 12).

Under the regulations, different criteria apply for granting resource consents or writing permitted activity rules depending on whether the drinking water concerned currently meets the health quality criteria or does not meet the health quality criteria. These terms are defined in regulations 4 and 5 with reference to the Drinking-water Standards for New Zealand 2005, a Ministry of Health publication, and the Water Information New Zealand database maintained on behalf of the Ministry of Health (currently by ESR (Environmental Science and Research)).

The circumstances in which the regulations apply also vary depending on—

the number of people that are supplied with drinking water; and
the number of days in each calender year that the people are supplied with the drinking water.

Regulation 13 authorises a consent authority to impose requirements in relation to rules in a plan or resource consents that are more stringent than the requirements in the regulations.

Regulations 14 and 15 are transitional provisions and set out when a regional council must comply with regulation 10 (which relates to rules for permitted activities).

Issued under the authority of the Acts and Regulations Publication Act 1989.

Date of notification in Gazette: 20 December 2007.

Notes

1 General

This is a reprint of the Resource Management (National Environmental Standards for Sources of Human Drinking Water) Regulations 2007. The reprint incorporates all the amendments to the Resource Management (National Environmental Standards for Sources of Human Drinking Water) Regulations 2007 as at 21 December 2007, as specified in the list of amendments at the end of these notes.

Relevant provisions of any amending enactments that have yet to come into force or that contain relevant transitional or savings provisions are also included, after the principal enactment, in chronological order.

2 Status of reprints

Under section 16D of the Acts and Regulations Publication Act 1989, reprints are presumed to correctly state, as at the date of the reprint, the law enacted by the principal enactment and by the amendments to that enactment. This presumption applies even though editorial changes authorised by section 17C of the Acts and Regulations Publication Act 1989 have been made in the reprint.

This presumption may be rebutted by producing the official volumes of statutes or statutory regulations in which the principal enactment and its amendments are contained.

3 How reprints are prepared

A number of editorial conventions are followed in the preparation of reprints. For example, the enacting words are not included in Acts, and provisions that are repealed or revoked are omitted. For a detailed list of the editorial conventions, see http://www.pco.parliament.govt.nz/legislation/reprints.shtml or Part 8 of the Tables of Acts and Ordinances and Statutory Regulations, and Deemed Regulations in Force.

4 Changes made under section 17C of the Acts and Regulations Publication Act 1989

Section 17C of the Acts and Regulations Publication Act 1989 authorises the making of editorial changes in a reprint as set out in sections 17D and 17E of that Act so that, to the extent permitted, the format and style of the reprinted enactment is consistent with current legislative drafting practice. Changes that would alter the effect of the legislation are not permitted.

A new format of legislation was introduced on 1 January 2000. Changes to legislative drafting style have also been made since 1997, and are ongoing. To the extent permitted by section 17C of the Acts and Regulations Publication Act 1989, all legislation reprinted after 1 January 2000 is in the new format for legislation and reflects current drafting practice at the time of the reprint.

In outline, the editorial changes made in reprints under the authority of section 17C of the Acts and Regulations Publication Act 1989 are set out below, and they have been applied, where relevant, in the preparation of this reprint:
- •omission of unnecessary referential words (such as “of this section” and “of this Act”)
- •typeface and type size (Times Roman, generally in 11.5 point)
- •layout of provisions, including:
  - •indentation
  - •position of section headings (eg, the number and heading now appear above the section)
- •format of definitions (eg, the defined term now appears in bold type, without quotation marks)
- •format of dates (eg, a date formerly expressed as “the 1st day of January 1999” is now expressed as “1 January 1999”)
- •position of the date of assent (it now appears on the front page of each Act)
- •punctuation (eg, colons are not used after definitions)
- •Parts numbered with roman numerals are replaced with arabic numerals, and all cross-references are changed accordingly
- •case and appearance of letters and words, including:
  - •format of headings (eg, headings where each word formerly appeared with an initial capital letter followed by small capital letters are amended so that the heading appears in bold, with only the first word (and any proper nouns) appearing with an initial capital letter)
  - •small capital letters in section and subsection references are now capital letters
- •schedules are renumbered (eg, Schedule 1 replaces First Schedule), and all cross-references are changed accordingly
- •running heads (the information that appears at the top of each page)
- •format of two-column schedules of consequential amendments, and schedules of repeals (eg, they are rearranged into alphabetical order, rather than chronological).
