Part 7 E+W Nutrient pollution standards

168 Nutrient pollution standards to apply to certain sewage disposal works E+W

(1) After section 96A of the Water Industry Act 1991 insert—

“96B Nutrient pollution standards to apply to certain sewage disposal works

(1) A sewerage undertaker whose area is wholly or mainly in England must—

(a) in the case of each nitrogen significant plant comprised in its sewerage system—

(i) secure that, by the upgrade date, the plant will be able to meet the nitrogen nutrient pollution standard, and

(ii) on and after the upgrade date, secure that the plant meets that standard;

(b) in the case of each phosphorus significant plant comprised in its sewerage system—

(i) secure that, by the upgrade date, the plant will be able to meet the phosphorus nutrient pollution standard, and

(ii) on and after the upgrade date, secure that the plant meets that standard.

(2) In carrying out the duty under subsection (1), a sewerage undertaker must consider whether nature-based solutions, technologies and facilities relating to sewerage and water could be used to meet the standard.

(3) “Nitrogen significant plant” means a plant in England that—

(a) discharges treated effluent into a nitrogen sensitive catchment area, and

(b) is not an exempt plant in relation to the nitrogen nutrient pollution standard.

(4) “Phosphorus significant plant” means a plant in England that—

(a) discharges treated effluent into a phosphorus sensitive catchment area, and

(b) is not an exempt plant in relation to the phosphorus nutrient pollution standard.

96C Sensitive catchment areas

(1) Where the Secretary of State considers that a habitats site that is wholly or partly in England is in an unfavourable condition by virtue of pollution from nutrients in water comprising nitrogen or compounds of nitrogen, the Secretary of State may designate the catchment area for the habitats site as a nitrogen sensitive catchment area.

(2) Where the Secretary of State considers that a habitats site that is wholly or partly in England is in an unfavourable condition by virtue of pollution from nutrients in water comprising phosphorus or compounds of phosphorus, the Secretary of State may designate the catchment area for the habitats site as a phosphorus sensitive catchment area.

(3) In determining—

(a) whether a habitats site is in an unfavourable condition by virtue of pollution from nutrients comprising nitrogen, phosphorus or compounds of nitrogen or phosphorus,

(b) the catchment area for a habitats site, or

(c) whether to exercise the power in subsection (4)(e),

the Secretary of State may take into account, in particular, advice from, or guidance published by, Natural England, the Environment Agency or the Joint Nature Conservation Committee.

(4) A designation under subsection (1) or (2)—

(a) must be in writing,

(b) must be published as soon as practicable after being made,

(c) takes effect—

(i) on the day specified in the designation, or

(ii) if none is specified, on the day on which it is made,

(the “designation date”),

(d) if it takes effect after the end of the initial period, must specify the upgrade date (see section 96E(1)(b)), and

(e) may specify the concentration that applies to a plant (which discharges into the catchment area) in relation to a nutrient pollution standard instead of the standard concentration.

(5) A date specified under subsection (4)(d) as the upgrade date must be at least 7 years after the designation date.

(6) Before specifying a concentration under subsection (4)(e), the Secretary of State must consult the Environment Agency.

(7) A concentration specified under subsection (4)(e) ceases to have effect if, after the day on which the designation is made, the plant becomes an exempt plant.

(8) A designation under this section may not be revoked; and it is immaterial for the purposes of the continued designation of an area whether subsection (1) or (2) continues to be satisfied in relation to it.

(9) In this section “catchment area”, in relation to a habitats site, means the area where water, if released, would drain into the site.

96D Exempt sewage disposal works

(1) A plant is exempt in relation to a nutrient pollution standard if—

(a) it has a capacity of less than a population equivalent of 2000 when the designation of the associated catchment area takes effect,

(b) it has been designated by the Secretary of State as exempt in relation to the standard, or

(c) it is exempt in relation to the standard under regulations under subsection (8).

This is subject to subsection (2).

(2) The Secretary of State may designate a plant as not being exempt in relation to a nutrient pollution standard, unless—

(a) the plant has a capacity of less than a population equivalent of 250, and

(b) the designation takes effect after the designation of the associated catchment area takes effect.

(3) A designation under subsection (1)(b) or (2)—

(a) must be in writing,

(b) must be published as soon as practicable after being made, and

(c) takes effect—

(i) on the day specified in the designation, or

(ii) if none is specified, on the day on which it is made.

(4) A designation under subsection (2) that takes effect after the designation of the associated catchment area takes effect must specify the upgrade date (see section 96E(2)(a)).

The upgrade date must be at least 7 years after the designation under subsection (2) takes effect.

(5) A designation under subsection (2) may specify the concentration that applies to a plant in relation to a nutrient pollution standard instead of the standard concentration.

(6) Before specifying a concentration under subsection (5), the Secretary of State must consult the Environment Agency.

(7) A concentration specified under subsection (5) ceases to have effect if, after the day on which the designation is made, the plant again becomes an exempt plant.

(8) The Secretary of State may by regulations specify plants or descriptions of plant that are to be exempt in relation to a nutrient pollution standard.

(9) Subsections (10) and (11) apply where a plant that is exempt under regulations under subsection (8) can, by virtue of the regulations, cease to be exempt.

(10) The regulations must specify or provide for determining the upgrade date (see section 96E(2)(b)) in relation to any plant that ceases, by virtue of the regulations, to be an exempt plant in relation to a standard after the designation of the associated catchment area takes effect.

The upgrade date must be at least 7 years after the plant ceases to be exempt in relation to the standard.

(11) The regulations may provide for the Secretary of State to specify the concentration that applies to a plant that ceases, by virtue of the regulations, to be an exempt plant in relation to a nutrient pollution standard instead of the standard concentration; and, if such provision is made, the regulations must—

(a) require that the Secretary of State consult the Environment Agency before specifying a concentration;

(b) provide for any specified concentration to cease to have effect if, after the day on which the plant ceases to be an exempt plant, the plant again becomes an exempt plant.

(12) A designation under subsection (2) in relation to a plant and a nutrient pollution standard is of no effect if the plant ceases, by virtue of regulations under subsection (8), to be exempt in relation to the standard before, or at the same time as, the designation would otherwise take effect.

(13) In this section “population equivalent” has the meaning given by regulation 2(1) of the Urban Waste Water Treatment (England and Wales) Regulations 1994 (S.I. 1994/2841).

(14) References in this section to the designation of an associated catchment area are to its designation as a sensitive catchment area.

96E Upgrade date

(1) The upgrade date, in relation to a nutrient significant plant, is, unless subsection (2) or (3) applies—

(a) 1 April 2030, if the designation of the associated catchment area takes effect during the initial period;

(b) the date specified under section 96C(4)(d), if the designation of the associated catchment area takes effect after the end of the initial period.

(2) But, if the plant becomes a nutrient significant plant after the designation of the associated catchment area takes effect, the upgrade date is—

(a) the date specified under section 96D(4), where it becomes a nutrient significant plant by virtue of a designation under section 96D(2);

(b) the date specified by or determined under provision made by virtue of section 96D(10), where it becomes a nutrient significant plant on ceasing, by virtue of regulations under section 96D(8), to be exempt.

(3) Where the associated catchment area has ceased to be a catchment permitting area and a date has been specified under section 96H(4)(c), that date is the upgrade date.

(4) “The initial period” means the period of 3 months beginning with the date on which the Levelling-up and Regeneration Act 2023 is passed.

(5) References in this section to the designation of an associated catchment area are to its designation as a sensitive catchment area.

(a) the standard concentration applied to nutrient significant plants, and

(b) the nutrient significant plants were (on that basis) meeting the nutrient pollution standard on and after the applicable date.

(5) For that purpose, a condition imposed on an environmental permit in pursuance of subsection (3)(b) may, in particular—

(a) require, or have the effect of requiring, that the concentration of nutrients in treated effluent discharged by a plant is higher or lower than, or equal to, the standard concentration;

(a) paragraph (a) were omitted, and

(b) in paragraph (b)—

(i) for “those permits” there were substituted “the permit”;

(ii) for “those plants” there were substituted “the plant”;

(iii) for “Chapter 3” there were substituted “Chapter 2”.

(8) It is for the Environment Agency to determine the overall effect on a habitats site of nutrients in treated effluent.

(9) Regulations made by the Secretary of State may specify how such determinations are to be made.

(10) In this section “nutrients”, in relation to an area designated under—

170 Remediation E+W

(1) The Environmental Damage (Prevention and Remediation) (England) Regulations 2015 (S.I. 2015/810) are amended as follows.

(2) After regulation 9 insert—

“9A Nutrient significant sewage disposal works: environmental damage

(1) This regulation applies where a sewerage undertaker whose sewerage system includes a nutrient significant plant fails to secure that the plant is able to meet the related nutrient pollution standard by the upgrade date.

(2) Any excess nutrient pollution is to be treated for the purposes of these regulations as damage to the related habitats site that is environmental damage caused by an activity of the sewerage undertaker that—

(a) requires a permit under the Environmental Permitting (England and Wales) Regulations 2016, and

(b) falls within Schedule 2.

(3) In paragraph (2)—

• “excess nutrient pollution”, in relation to a nutrient significant plant and a related nutrient pollution standard, means the amount by which the total nutrient pollution discharged in treated effluent by the plant during the period—

  (a)

  beginning with the upgrade date, and

  (b)

  ending with the day the plant first meets the related nutrient pollution standard,

  exceeds the total nutrient pollution that it would have discharged in treated effluent during that period had it met the related nutrient pollution standard on and after the upgrade date;

• “total nutrient pollution” means—

  (a)

  in relation to the nitrogen nutrient pollution standard, total nitrogen, and

  (b)

  in relation to the phosphorus nutrient pollution standard, total phosphorus.

(4) Where—

(a) the nutrient significant plant referred to in paragraph (1) is a plant that discharges treated effluent into a catchment permitting area (see section 96G of the Water Industry Act 1991), and

(b) the sewerage undertaker has failed to comply with a condition in the environmental permit for the plant imposed in pursuance of subsection (3)(b) of that section,

the definition of “excess nutrient pollution” in paragraph (3) is subject to the following modifications.

(5) In a case where the condition relates to the total nutrient pollution discharged by the plant specifically, references in that definition to the “upgrade date” are to be read as the “applicable date”.

(6) In a case where the condition relates to the total nutrient pollution discharged by all plants that discharge into the associated catchment area, that definition is to be read as if—

(a) in the words before paragraph (a), after “by the plant” there were inserted “and all other plants that discharged into the associated catchment area for that plant”,
