§ 14-109. Sewage sludge holding tanks.

(a)

It is necessary that all sewage sludge application sites governed by this article have sewage sludge holding tank facilities installed on the premises. These holding tanks are necessary to provide a mechanism for the pathogen and vector reduction process, as well as to provide a temporary holding facility for sewage sludge during periods of adverse weather. These holding tanks shall meet the following requirements:

(1)

No overflow or leakage of sewage sludge may be allowed from the surface onto the ground surface, into the surface waters or the groundwater table.

(2)

A 60-pound turn-down lid shall be installed on the holding tanks and shall be closed at all times, except when employees of the license holder, or other duly authorized individuals, are present.

(3)

Odors from such tanks are to be controlled at all times.

(4)

During periods of pumping into or out of holding tanks, citronella or other odor-controlling spray shall be released in the air sufficient to abate any odor occasioned by the transfer process.

(5)

After periods of pumping sewage sludge into or out of holding tanks, all equipment, tanks, and grounds shall be hosed down such that all sewage sludge is washed off the equipment, tanks, and grounds.

(6)

Sewage sludge is to be removed from the holding tanks to the land application equipment as soon as weather and soil conditions permit.

(b)

Prior to the installation of sewage sludge storage handling tanks, each such tank shall be inspected and approved by a representative of the county. The inspector shall make findings with respect to structural integrity, rusting, holes, cracks, fissures, and any other evidence of deterioration or structural unsoundness. Any tanks determined to be structurally unsound or otherwise susceptible to leaking or failure shall not be approved for installation or use at the facility.
