Section 391.303  Off-Site

Interim Storage of Liquid Anaerobic Sludge

The Agency will not issue a

permit for the off-site interim open storage of liquid anaerobic sludge unless

the applicant submits proof that the storage facility will not cause or

threaten to allow air or water pollution.  In addition to the general criteria

under Section 391.302(b), the following items shall be addressed by the

applicant in the design of closed storage facilities.

a)         Closed storage facilities shall have an air breather vent

pipe(s) capped to preclude the entrance of precipitation.  Minimum height from

top of vent to ground level shall be 10 feet.

b)         Appropriate signs shall be posted in the immediate vicinity of

the storage facility, which as a minimum must state, "Danger – No

Smoking."

c)         Closed storage facilities shall incorporate into the vent

system adsorptive devices to minimize emissions of odorants.

d)         An alarm system shall be installed in the storage container

vapor space to actuate should an explosive situation be produced in the storage

facility.

e)         Electrical equipment in, on or in the immediate vicinity of

the closed storage facility shall comply with the National Electric Code

requirements adopted by the National Fire Protection Association, 1981 for

Class 1, Group D, Division 1 locations.  Any forced air ventilation equipment

shall be fabricated from nonsparking material.

f)         Operating personnel access shall be provided for all closed

liquid storage facilities.  Self-contained oxygen-supplying equipment shall be

available for use upon entrance into such facilities.

g)         Closed liquid storage facilities must be constructed with

relatively impermeable materials such as clay, concrete, synthetic liner or

equivalent.
