recalcining lime, or regenerating activated carbon.

(4) SEWAGE TREATMENT PLANT means any arrangement of devices

and structures for the treatment of sewage and all

and other waste byproducts.

(b) Emission Standard

This rule applies to municipal sewage treatment sludge

incinerators the construction, modification or

reconstruction of which commenced after June 11, 1973.

On and after the date on which the performance test required

to be conducted by Rule 902 (b)(1) is completed, no owner or

gases which:

(1) Contain particulate matter at a rate in excess of 0.65

The owner or operator of any sludge incinerator subject to

the provisions of this rule shall:

(1) Install, calibrate, maintain, and operate a flow

measuring device which can be used to determine either

the mass or volume of sludge charged to the

incinerator. The flow measuring device shall have an

accuracy of +or- five percent over its operating range.

mixed representative grab sample of the sludge can be

obtained.
