CORRAL OR PEN MAINTENANCE

1. Grooming frequency Corrals scraped and groomed at least every 48 hours. Corrals groomed at least twice each week**Required by law in Maricopa County Corrals groomed once each week. Corrals groomed less than once each week.
2. Scraping depth Solids scraping leaves 1-2 inches of solids over the soil. Solids scraping leaves 2-4 inches of solids over the soil. Solids scraping leaves 4-6 inches of solids over the soil. Solids scraping either breaks through manure cap, orleaves morethan 6 inches of manure.
3. Mounds and slopes Corral pens groomed with mounds and slopes to prevent ponding of water.
No mounds or slopes present in corrals/pens, butponded water is not common. No mounds or slopes present in corrals/pens, and ponded water is common.
4. Water troughs and lines All lines maintained in good repair, and

troughs have concrete aprons to prevent soil saturation.


Lines maintained, butthere are noconcrete aprons around troughs. Lines leak, troughs leak, andsoil issaturated with water around troughs.

STORAGE OF SOLID WASTES

5. Storage Pad Solids stored on concrete pad, oron clay pad compacted to 95% of maximum compaction

Solids stored on uncompactedsoil.
6. Run-on water Solids storage area protected from run-on water up to a 25-year 24-hour storm event.* *Storm event size varies statewide. In Maricopa County for example, it is about 3 inches. Call your NRCS office for the storm event size in your area.

Solids storage area notprotected from run-on water up to a 25-year, 24-hour storm event..
7. Corral runoff All rainwater runoff from corrals and pens is routed and conveyed to storm water storage pond or detention basin.

Rainwater runoff from corrals and pens is notrouted and conveyed to storm water storage.
8. Storm water storage Storm water ponds or detention basins are lined with compacted clay, clay loam, or plastic liners.

Storm water ponds and detention basins have nolining at all.
9. Storage design Storm water ponds or detention basins are designed to contain runoff up to a 25-year 24-hour storm event.

Storm water ponds and detention basins cannot contain all runoff up to a 25-year, 24-hour storm event.

FLOOD PROTECTION

10. Flooding of corrals Corrals protected from run-on water by proper siting or berming up to a 25-year, 24-hour storm event.

Corrals notprotected from run-on water by proper siting or berming up to a 25-year, 24-hour storm event.
11. Flooding of ponds Storm water ponds or detention basins protected from run-on water by proper siting or berming up to a 25-year, 24-hour storm event.

Storm water ponds and detention basins notprotected from run-on water up to a 25-year, 24-hour storm event.
12. Site plan for entire facility Site plan has been developed by Natural Resources Conservation Service or qualified private engineer.

No site plan exists.

SAFETY

13. Fencing All storm water ponds or detention basins are fenced to prevent accidents.

No fencing is present to prevent accidents.
14. Ventilation All enclosed solids storage areas are vented to prevent buildup of dangerous gases. (Poultry producers should pay particular attention to this danger.)

No enclosed solids storage areas are vented.
