CORRAL OR PEN MAINTENANCE
1 Grooming frequency Corrals scraped and groomed at least every 48 hours. Corrals groomed at least twice each week* 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, or

leaves more than 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,

but

ponded 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, but

there are no concrete aprons around troughs.

Lines leak, troughs leak, and

soil is saturated with water around troughs.

5 Storage pad Solids stored on concrete pad, or

on clay pad compacted to 95% of maximum compaction

------ ------ Solids stored on uncompacted soil.
6 Run-on water Solids storage area protected from run-on water up to a 25-year 24-hour storm event.* ------ ------ Solids storage area not protected 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 not routed 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 no lining 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 not protected 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 not protected 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.
