TABLE 8. Compost Site Filter Strip
				  Requirements*

							 Composters
Facilities with > 700 AUs or Commercial
							 Composters
COMMENT
Filter strip width parallel to the contour down slope
							 from compost pad
For pads less than 25 feet in
							 width
:
minimum width of 25 feet along the downslope
							 side of the compost pad
For pads > 25 feet but less than 200
							 ft&
:
Minimum of 1 ft
							 filter width for each 1 ft of impervious pad width up to 50 feet. Then 1 ft of
							 filter strip width for each 2 feet of impervious pad width between 50 and 200
							 ft.
*** Note: Pads must also meet the setback requirements
							 in Table 6, which may be greater than the filter strip width.
Filter strip length perpendicular to the contour
Equal to or greater than the length of the compost pad
							 parallel to the contour
Equal to or greater than the length of the compost pad
							 parallel to the contour
***
Minimum Depth to hardpan or water table+
10 inches
15 inches
Minimum Depth to bedrock+
18 inches
24 inches
Vegetative cover Maintenance**
Herbaceous vegetation
							 (grass):
mow 1 or 2 times/yr ;
forest
							 cover:
maintain forest stand and organic duff layer
Run off flow through filter strip
Grade or use stone or erosion and sediment
							 control mulch berm to direct flow as sheet flow at upslope edge of filter
							 strip. For herbaceous filter strips more than 100 ft in width include a mulch
							 or stone berm every 50' to redistribute flow into sheet flow.
*** Maintain as sheet flow, repair any concentrated
							 flow channels.
Depth to Sand or Gravel Layers+
6"
12"
Erosion and Sediment Control
Disturbed soils shall be stabilized. No
							 traffic shall be allowed in filter strip until vegetation has been well
							 established.
Filter strip slope
<=10% slope++;
* Requirements are for new facilities. For existing
				  facilities or new facilities on existing farming operations that only use farm
				  generated materials, reductions to these standards may be authorized by the
				  Commissioner.
** Vehicle traffic shall be minimized within the filter strip
				  to minimize compaction of the soil, rutting, and damage to the
				  vegetation.
*** May be adjusted with permission of the Commissioner based
				  on site specific conditions and management techniques
& Pads greater than 200 ft in width shall require a
				  filter strip designed on a site specific basis by a qualified
				  professional.
+ May be achieved by engineering techniques such as diversion
				  ditches, curtain drains or adding fill. Permits may be required for altering
				  wetlands to comply with filter strip requirements.
++ For sites > 10% but less than 20%
				  slope:
Site specific modifications may be allowed with permission
				  of the Commissioner.
