is grown. This includes range land and land used as pasture.

    (b) Agronomic rate is the whole sludge application rate (dry weight 

basis) designed:

    (1) To provide the amount of nitrogen needed by the food crop, feed 

crop, fiber crop, cover crop, or vegetation grown on the land; and

    (2) To minimize the amount of nitrogen in the sewage sludge that 

passes below the root zone of the crop or vegetation grown on the land 

to the ground water.

    (c) Annual pollutant loading rate is the maximum amount of a 

pollutant that can be applied to a unit area of land during a 365 day 

period.

    (d) Annual whole sludge application rate is the maximum amount of 

sewage sludge (dry weight basis) that can be applied to a unit area of 

land during a 365 day period.

    (e) Bulk sewage sludge is sewage sludge that is not sold or given 

away in a bag or other container for application to the land.

    (f) Cumulative pollutant loading rate is the maximum amount of an 

inorganic pollutant that can be applied to an area of land.

    (g) Forest is a tract of land thick with trees and underbrush.

    (h) Land application is the spraying or spreading of sewage sludge 

onto the land surface; the injection of sewage sludge below the land 

surface; or the incorporation of sewage sludge into the soil so that the 

sewage sludge can either condition the soil or fertilize crops or 

vegetation grown in the soil.

    (i) Monthly average is the arithmetic mean of all measurements taken 

during the month.

    (j) Other container is either an open or closed receptacle. This 

includes, but is not limited to, a bucket, a box, a carton, and a 

vehicle or trailer with a load capacity of one metric ton or less.

    (k) Pasture is land on which animals feed directly on feed crops 

such as legumes, grasses, grain stubble, or stover.

    (l) Public contact site is land with a high potential for contact by 

the public. This includes, but is not limited to, public parks, ball 

fields, cemeteries, plant nurseries, turf farms, and golf courses.

    (m) Range land is open land with indigenous vegetation.

    (n) Reclamation site is drastically disturbed land that is reclaimed 

using sewage sludge. This includes, but is not limited to, strip mines 

and construction sites.
