(a) Common requirements. Requirements common to all composting facilities:

1. (1) The operation shall be conducted in a manner which precludes:

   1. (A) Pollution;
   2. (B) Public health hazards;
   3. (C) Nuisances;
   4. (D) Odors; and
   5. (E) The harborage of vectors;
2. (2) Operation of the facility shall follow acceptable methods of composting which result in the aerobic biochemical degradation of the organic material received; and
3. (3) All operations shall be performed by licensed on-site operators who are certified in accordance with Licensing of Operators of Solid Waste Management Facilities and Training and Certification Requirements for Environmental Officers, 8 CAR pt. 62, of the Arkansas Pollution Control and Ecology Commission during all hours of operation, and access to the facility shall be prohibited during nonoperating hours.

(b) Type Y operating requirements:

1. (1) A written operating record shall be maintained in accordance with 8 CAR § 60-808(a); and
2. (2) The operation shall conform to an approved written operating narrative that includes or addresses the requirements of this subpart.

(c) Type O and Type S operating requirements:

1. (1) The composting of sewage sludge shall meet the criteria for a process to further reduce pathogens and vector reduction as provided by 40 C.F.R. pt. 503;

2. (2)

   1. (A) The facility shall monitor and document the temperature of composting material to ensure that pathogen reduction criteria are met.
   2. (B) Temperature readings shall be recorded each operating day during the active composting period.
   3. (C) Once the pathogen and vector reduction requirements have been met or exceeded, monitoring may occur less frequently;

3. (3)

   1. (A) In order to minimize odors, the attraction of vectors and percolation of liquid waste through soils at the site, liquid and semiliquid wastes, sludges, sewage sludge (bio-solids), and septage shall be mixed with bulking agents or compost material as soon as practicable on the day they are received unless the operator satisfactorily demonstrates that severe conditions prohibit such activities.
   2. (B) In any event, all incoming waste shall be incorporated into the composting process within a maximum of three (3) days such that the liquid or sludge is promptly absorbed and not allowed to flow as free liquid from the bulking material or from the compost windrows.
   3. (C) Otherwise, the waste shall be disposed of at a permitted landfill at the end of the three-day period;
4. (4) Stored, finished compost that is not sold within six (6) months shall be removed or reprocessed for use or sale;
5. (5) A written operating record shall be maintained in accordance with 8 CAR § 60-808(b); and
6. (6) The operation shall conform to an approved written operating plan that includes or addresses the requirements of this subpart.
