**Silage/Feedstock Storage Area Evaluation**

Not to be used for vertical silos and silo bags.

1.  Does the feed storage area have appropriate separation to wells?
    (See back of sheet.)

> Yes No (Does not meet NR-812; Check with DNR)

2.  Is there evidence of leachate in the feed storage area (brown stain
    or pools of discolored liquid, concrete surface with cement missing,
    or burned-out vegetation downstream)?

> No *(0 pts)* Yes *(15 pts)* [  ]{.underline} points

3.  Is the feed in the storage area entirely covered to exclude rainfall
    from the feedstock?

> Yes *(0 pts)* No *(20 pts)* [  ]{.underline} points

4.  How much of the "first flush" of runoff is captured and stored from
    the feed storage area?

> 0.2 inches *(0 pts)* 0.05 inches *(10 pts)* None *(20 pts)*
> [  ]{.underline} points

5.  What feedstock is stored?

> Haylage *(0 pts)* Field Corn Silage *(5 pts)* Sweet Corn Silage*(10
> pts)* [  ]{.underline} points

6.  Does runoff from the feed storage area discharge directly (\< 100')
    to a concentrated\
    flow channel or to surface water?

> No *(0 pts)* Yes *(10 pts)* [  ]{.underline} points

7.  Is the feed storage area within a WQMA? (\<300 feet to a solid or
    dashed blue line on a USGS\
    7.5 quad map or site that is susceptible to groundwater
    contamination, or that has the potential\
    to be a direct conduit for contamination to reach groundwater or
    \<1000 feet to a lake)

> No *(0 pts)* Yes *(5 pts)* [  ]{.underline} points

8.  What is the size of the feedstock storage area?

> 0 - 1/4 ac. *(5 pts)* 1/4 - 1/2 ac. *(10 pts)* 1/2 - 1 ac. *(15 pts)*
> \>1 ac. *(20 pts)* [  ]{.underline} points

9.  Are soils map units (immediately down-slope of the feed storage
    area) listed on the\
    Wisconsin Conservation Planning Technical Note WI-1 appendix 1 "List
    of Soils with\
    High Potential for Leaching to Groundwater?"

> No *(0 pts)* Yes *(5 pts)* [  ]{.underline} points

10. Is loose or spoiled feed uncovered and stacked on the feed storage
    area?

> No *(0 pts)* Yes *(10 pts)* [  ]{.underline} points

11. Does the feed storage area have 2 feet of separation to RHWT and
    Bedrock?

> Yes *(0 pts)* No *(10 pts)* [  ]{.underline} points

12. What is the floor surface and soils directly below the floor?

> (See back side of sheet.) [  ]{.underline} points
