PART 1 REQUIREMENTS

Interpretation

1.—(1) In this Schedule—

“biodiversity units” means the product of the size of an area, and the distinctiveness and condition of the habitat it comprises to provide a measure of ecological value (as assessed using the Defra biodiversity off–setting metric);

“biodiversity off-setting scheme” means a scheme which will deliver biodiversity enhancements which must not be less than the off–setting value;

“Defra” means the Department for Environment, Food and Rural Affairs;

“Defra biodiversity off–setting metric” means the mechanism published by Defra to quantify impacts on biodiversity, which allows biodiversity losses and gains affecting different habitats to be compared and ensures offsets are sufficient to compensate for residual losses of biodiversity;

“heavy commercial vehicle” has the meaning given by section 138 (meaning of “heavy commercial vehicle”) of the 1984 Act(1);

“mean high water springs” or “MHWS” means the highest level which spring tides reach on average over a period of time;

“off-setting value” means the net biodiversity impact of the authorised development, calculated using the Defra biodiversity off–setting metric, measured in biodiversity units; and

“wharf outage” means circumstances caused by factors beyond the undertaker’s control in which waste, clay or sediment has not or could not be received at Work No. 4 for a period in excess of four consecutive days.

(2) References in this Schedule to part of the authorised development are to be construed as references to stages, phases or elements of the authorised development in respect of which an application is made by the undertaker under this Schedule, and references to commencement of part of the authorised development in this Schedule are to be construed accordingly.
