Regulations 2(1) and 16(2)

SCHEDULE 1Conditions for treatment of natural mineral waters and spring waters with ozone-enriched air

1.  Treatment of natural mineral waters and spring waters with ozone-enriched air may only be carried out if—

(a)it is for the purpose of separating compounds of iron, manganese, sulphur and arsenic from water in which they occur naturally at source;

(b)prior to treatment the requirements of paragraphs 3, 4 and 5 of Schedule 4 are satisfied; and

(c)the treatment does not have a disinfectant action.

2.  Treatment of natural mineral waters and spring waters with ozone-enriched air must not—

(a)modify the physico-chemical composition of the water in terms of its characteristic constituents; or

(b)leave residues in the water which could pose a risk to public health, or, in the case of the substances listed below, above the levels specified.

Treatment residueMaximum limit (μg/l)
Dissolved ozone50
Bromate3
Bromoform1

3.  A person seeking to have a treatment with ozone-enriched air authorised must—

(a)make application in writing to the relevant authority within whose area the water is extracted;

(b)permit representatives of that authority to examine the proposed method of treatment, and place of treatment, and take samples for analysis in accordance with regulation 17; and

(c)provide such information in support of the application as is requested by the relevant authority.

4.  The relevant authority must assess the application and any information in its possession and must authorise the treatment if it is satisfied that—

(a)the treatment is justified by the composition of the water at source;

(b)the person carrying out the treatment is taking all necessary measures to ensure that the treatment is effective and safe; and

(c)the treatment otherwise complies with paragraphs 1 and 2.

5.  Where the relevant authority decides to authorise a treatment pursuant to paragraph 4, it must inform the operator of the treatment in writing and state the date from which the authorisation for commercial use of the treatment has effect.

6.  Where the relevant authority refuses to authorise a treatment pursuant to paragraph 4, it must inform the operator of the treatment in writing, stating its reasons.

7.  Where a treatment has been authorised pursuant to paragraph 4, the person carrying out the treatment must, for the purpose of enabling the relevant authority to assess whether the conditions in paragraph 4(a) and (b) continue to be satisfied—

(a)permit representatives of the authority to examine the method of treatment and place of treatment and take samples for analysis in accordance with regulation 17; and

(b)provide such information related to the treatment as is requested by the authority.

8.  If the relevant authority is satisfied that the conditions specified in paragraph 4 are no longer fulfilled, it may withdraw authorisation of a treatment by giving the person operating that treatment a written notice stating the grounds for withdrawal.

9.  Where the relevant authority has informed an operator under paragraph 6 of its refusal to authorise a treatment under paragraph 4 or withdraws authorisation of a treatment under paragraph 8, the person who wishes to carry out the treatment may apply to the Agency for a review of that decision.

10.  Upon receiving the application for review, the Agency must make such inquiry into the matter as may seem to the Agency to be appropriate and, having considered the results of that enquiry and any relevant facts elicited by it, must either confirm the decision or direct the relevant authority to grant or restore, as appropriate, authorisation of the treatment process in operation. In the case of such a direction the relevant authority must thereupon comply with the said direction.

SCHEDULE 7Performance characteristics for analysing the constituents in Schedule 6

ConstituentAccuracy of parametric value in %Precision of parametric valueDetection limit of parametric value in %

Notes:

1.

The method of analysis used to measure the concentration of the constituents in Schedule 6 must be capable of measuring concentrations equal to the parametric value with the specified accuracy, precision and detection limits.

2.

Regardless of the sensitivity of the method of analysis, the result must be expressed to at least the same number of decimal places as the maximum limit set out in Schedule 6 for the particular constituent being analysed.

3.

Accuracy is the systematic error and represents the difference between the average value of a large number of repeated measurements and the exact value.

4.

Precision represents the random error and is expressed in general as the standard deviation (within a batch and between batches) of a sample of results from the average.

5.

Acceptable precision is equal to twice the relative standard deviation.

6.

The detection limit is—

(a)

three times the relative standard deviation within a batch of a natural sample containing a low concentration of the constituent; or

(b)

five times the relative standard deviation within a batch of a virgin sample.

7.

The method should make it possible to determine cyanide in all its forms.
