• Other systems. Use proprietary design and performance specifications that are commonly accepted and provide adequate odor mitigation.
Chemical or biological additives (E2) – Apply, to stored manure, chemical or biological additives that are scientifically proven to be effective in reducing odor from that manure when applied under applicable conditions and in applicable amounts.
Compost (E3) – Aerobically treat solid or semi-solid manure to create compost. Compost must have a carbon: nitrogen ratio of 25:1 to 40:1, and must consist of at least 40 to 60% moisture by weight. Composted material must be held at a temperature of more than 130° F. (54° C.) for more than 5 days.
Solids Separation and Reduction (E4) – Reduce the solid content of stored manure to an average of less than 2% solids through separation, multi-tiered pits or other means.
Water Treatment (E5) – Install and use a physical, chemical or biological process that removes the majority of contaminants from the waste stream, resulting in a liquid effluent meeting surface water discharge standards. The remaining solid fraction or sludge must be accounted for based on its form, and the management it is subject to.
Aeration (F1) – Use aeration equipment to maintain aerobic activity in stored manure. Aeration must maintain an average of 2 milligrams of dissolved oxygen per liter of manure stored in the upper foot of manure stored in the aerated structure between April and October.
Bio-cover (F2) – Cover the surface of waste storage structure with an 8″ to 12″ thick blanket of dry wheat, barley or good quality straw. The blanket must cover nearly all of the waste surface between the months of April and October. Add to the blanket as necessary (typically every 6 weeks to 4 months) to maintain the required cover.
Geotextile cover (F3) – Cover the surface of waste storage structure with a geotextile membrane that is at least 2.4 mm thick. The membrane must cover nearly all of waste surface between the months of April and October.
Impermeable cover (F4) – Cover the surface of waste storage structure with an impermeable barrier that prevents gas from escaping. Gas must be drawn off, and either treated or burned.
Natural crust (F5) – Maintain a natural crust of dry manure on the surface of stored manure. The natural crust must cover a substantial amount of the surface area of the stored manure, for most of the time between the months of April and October.
Bottom fill (F6) – Add manure to a liquid manure storage structure from the bottom so as to limit disturbance to the surface of the stored manure.
Worksheet 2 (continued)
Windbreak (G1) – Maintain a solid or porous windbreak, 10 to 50 feet from the odor source, which reduces forward momentum of airflow and vertically disperses the odor plume. The length of a windbreak shall be at least half of the perimeter of the waste storage facility. A windbreak may be constructed of vegetation or other materials. Vegetation windbreaks must contain at least 3 rows of trees and shrubs, of both fast and slow-growing species, that are well suited for the site. Windbreaks must be designed and constructed according to NRCS Technical Guide Standard 380 (June, 2002).
Animal Lots
Frequent cleaning of animal lot (H1) – Scrape and remove manure from animal lot surfaces at least once every 3 days. You may leave an undisturbed, compacted manure layer (1 to 2 inches thick) on the surface of unpaved animal lots to provide good surface sealing.
Drag animal lot (H2) – Drag manure in animal lots with harrow or disk at least once every 7 days during the months of April though October, to aerate and dry the manure.
Animal lot moisture control (I1) – Prevent runoff water from flowing onto animal lots from roofs and other surfaces. Use diversions or roof runoff systems identified in s. ATCP 50.70 or 50.85. Animal lots must have a grade of at least one percent to promote drainage and drying. Windbreak (J1) – Maintain a solid or porous windbreak, 10 to 50 feet from the odor source, which reduces forward momentum of airflow and vertically disperses the odor plume. The length of a windbreak shall be at least half of the perimeter of the animal lot. A windbreak may be constructed of vegetation or other materials. Vegetation windbreaks must contain at least 3 rows of trees and shrubs, of both fast and slow-growing species, that are well suited for the site. Windbreaks must be designed and constructed according to NRCS Technical Guide Standard 380 (June, 2002).

1 Treat multiple lots as one animal lot if runoff from the animals lots drains to the same treatment area or if runoff from the animal lot treatment areas converges or reaches the same surface water within 200 feet of any of those treatment areas.
2 Indicated by a solid or dashed blue line on a 1:24,000 scale USGS topographic map.
3 “Minor alterations” are repairs or improvements that do not result in a substantially altered animal lot. “Minor alterations” may include conservation practices such as runoff diversions, contouring, and planting vegetation.
4 Runoff may be diverted by means of earthen diversions, curbs, walls, gutters, waterways or other practices, as appropriate.
5 Use safe methods to dispose of collected leachate. For example, leachate may be transferred to waste storage structures and then applied to land at agronomic rates.
