14 Excavation & Tips Rules (See QNJAC Information Sheet 2)

QR Regulation 31 requires the operator to ensure that suitable and sufficient rules are made to ensure the safe construction and operation of excavations and tips. These rules are known as the Excavations and Tips Rules (E & T). The E & T rules are required to describe the manner in which these activities are carried out, the extent of supervision and the precautions to be taken. The geotechnical specialist must review and comment on the E & T Rules during the assessment or when there is a
significant change.

15 Appraisal of the Excavation and Tips

QR Regulation 32 requires the operator to ensure that a suitable and sufficient appraisal of all excavations and tips are undertaken by a competent person to determine whether or not a significant hazard exists. For those features deemed to represent a significant hazard, a geotechnical assessment is required (QR Regulation 33). For nonsignificant hazards the frequency of appraisals should be determined by the competent person.

16 Definition of a Geotechnical Assessment

QR Regulation 33 defines the “geotechnical assessment” as “an assessment carried out by a geotechnical specialist identifying and assessing all factors liable to affect the stability and safety of a proposed or existing excavation or tip.” A geotechnical assessment must address all relevant parts of Schedule 1. The operator must ensure that a suitably qualified geotechnical specialist (See definition in QR Regulation 2) completes an assessment. If remedial work is required as a result of the assessment, it must be carried out in the required timescale stated in the assessment.

If the conclusion of the assessment is that the feature is a significant hazard, then a geotechnical assessment must be undertaken at least every 2 years or such shorter period as specified by the geotechnical specialist in his report. If the conclusion is that the feature is a nonsignificant hazard then the frequency of appraisals should be determined by the geotechnical specialist.

17 Tip Records

QR Regulation 36 requires the operator to “ensure that sufficient records are kept of the nature, quantity and location of all substances accumulated or deposited in a notifiable tip to enable an accurate assessment of the stability of that tip to be made”.

18 Notification of Excavations and Tips

QR Regulation 37 requires the operator to ensure that he notifies the HSE at least 30 days before commencing or re-commencing work on an excavation or tip that either is or is expected to become a significant hazard. The operator must also inform the HSE when the structure ceases to become a significant hazard. (An example of a notification form is shown in Appendix 1)

19 Worker Participation

QR Regulation 40 requires the operator to make and maintain arrangements to ensure that all managers and operatives (including contractors) are able to review, discuss and continuously improve all aspects of health and safety at the quarry, including the geotechnical management process.
