Section 61-43.100.150 - Odor Control Requirements

A. The Animal Facility Management Plan shall contain an odor abatement plan for the swine facility, lagoon, treatment system, manure storage pond, and manure utilization areas. The plan shall consist of the following:

1. Operation and maintenance practices which are used to eliminate or minimize undesirable odor levels in the form of a Best Management Plan for Odor Control;

2. Use of treatment processes for the reduction of undesirable odor levels;

3. Additional setbacks from property lines beyond the minimum setbacks given in this part;

4. Other methods as may be appropriate; or

5. Any combination of these methods.

B. Producers shall utilize Best Management Practices normally associated with the proper operation and maintenance of a swine facility, lagoon, treatment system, manure storage pond, and any manure utilization area to ensure an undesirable level of odor does not exist.

C. No producer may cause, allow, or permit emission into the ambient air of any substance or combination of substances in quantities that an undesirable level of odor is determined to result unless preventive measures of the type set out below are taken to abate or control the emission to the satisfaction of the Department. When an odor problem comes to the attention of the Department through field surveillance or specific complaints, the Department shall determine if the odor is undesirable.

D. If the Department determines an undesirable level of odor exists, the Department may require these abatement or control practices, including, but not limited to, the following:

1. Remove or dispose of odorous materials;

2. Methods in handling and storage of odorous materials that minimize emissions;

a. Dry to a moisture content of fifty percent (50%) or less;

b. Solids separation from liquid manure, and composting of solids;

c. Use disinfection to kill microorganisms present in manure;

d. Aerate manure;

e. Anaerobic digestion in a sealed vessel;

f. Compost solid manure and other swine by-products;

g. Utilize odor control additives.

3. Prescribed standards in the maintenance of premises to reduce odorous emissions;

a. Filtration (biofilters or other filter used to remove dust and odor) of ventilation air;

b. Keep animals clean and separate from manure;

c. Adjust number of animals confined in the pens or paddocks in accordance with Clemson University Animal Space Guidelines;

d. Frequent removal of manure from animal houses;

e. Add a layer of water in the shallow pits after the manure is removed;

f. Feeding areas should be kept dry, and waste feed accumulation should be minimized;

g. Maintain feedlot surfaces in a dry condition (twenty-five to forty percent (25 to 40% moisture content), with effective dust control;

h. Proper maintenance of the dead swine disposal system;

i. Cover or reduce the surface area of manure and other swine by-products storage. (Vents shall be provided for release of pressure created by manure gases if completely sealed covers are used);

j. Plant trees around or downwind of the manure and other swine by-products storage and treatment facilities (trees shall not be planted within 25 feet of the toe of the dike);

k. Incorporate manure and other swine by-products immediately after land application; and

l. Select appropriate times for land application.

4. Best Available Technology to reduce odorous emissions.

E. Nothing in this section prohibits an individual or group of persons from bringing a complaint against a swine facility, including problems at lagoons, treatment systems, manure storage ponds, and manure utilization areas.

F. If the permittee fails to control or abate the odor problems at a swine facility, lagoon, treatment system, manure storage pond, and any manure utilization area to the satisfaction and within a time frame determined by the Department, the permit may be revoked. If the permittee fails to control or abate the odor problems at land application sites, approval for land application of manure on the manure utilization area in question may be revoked. Additional land may be required to be added to the Animal Facility Management Plan, if necessary, to provide a sufficient amount of land for manure utilization.
