Citation and commencement

1. These rules may be cited as the Mines and Quarries (Tipping Plans) Rules 1971 and shall come into operation on 1st October 1971.

Interpretation

2. The Interpretation Act 1889 shall apply to the interpretation of these rules as it applies to the interpretation of an Act of Parliament.

Application

3. The provisions of these rules shall apply to all such plans and sections of active or closed tips associated with mines and quarries and to all such sections of the strata underlying these tips as are required to be kept in pursuance of regulations 13(c) and 20(1)(c) of the Mines and Quarries (Tips) Regulations 1971 (1).

Scale of plans and sections

4. Every such plan shall be on a scale of not less than 1/2500 and every such section shall be on a scale of not less than 1/1250.

Correlation with Grid

5. Every such plan shall be orientated to and correlated with the Ordnance Survey National Grid and marked with squares corresponding to the 100 metre squares shown on Ordnance Survey sheets on the scale of 1/2500.

Contour Lines, Gradient and Faults

6.-(1) Every such plan shall be marked with contour lines showing vertical variations from Ordnance Datum at intervals not exceeding five metres.

(2) In every case the vertical variation represented by any consecutive contour lines marked on every such plan shall be the same throughout the plan and the lines shall be marked with the height relative to the Ordnance Datum.

(3) Every such plan shall show the general direction and rate of dip of the strata underlying the tip.

(4) Every such plan and section shall show, so far as it can be ascertained, the position of any known fault which may affect the security of the tip.

Topographical features

7. Every such plan shall show all mine workings (whether abandoned or not), previous landslips, springs, artesian wells, watercourses and other natural and other topographical features which might affect the security of the tip or might be relevant for determining whether the land on which tipping operations are to be carried out is satisfactory for the purpose.

Design etc

8. Every such plan and section shall show the land covered or to be covered by the refuse to be deposited, the designed height for the time being of the tip, the designed contours and boundaries for the time being of the tip and the nature and location of the types of refuse deposited at the tip up to a date not more than fifteen months past or such other date as an inspector may require in any particular case.

Correlation

9. Every such plan shall indicate-

(a)the direction of the National Grid North;

(b)the date on which it was made; and

(c)the date on which it was last revised.

EXPLANATORY NOTE

These rules, made under section 6(2) of the Mines and Quarries (Tips) Act 1969, lay down the scales, orientation, correlation with the National Grid and other requirements affecting the plans and sections of tips associated with mines and quarries and of the strata underlying the tips which the Mines and Quarries (Tips) Regulations 1971 require to be kept.
