B.
Buffer Zones.

				requirements as specified in Table 1. The Department may specify that buffer
				zones be increased, as necessary, depending on site conditions, to prevent
				environmental or health impacts.

C.
Minimum Depth to Bedrock.
A site may not be located on land areas where
				the bedrock is less than thirty-six (36) inches below the ground surface. Up to
				twelve (12) inches of soil meeting U.S.D.A. textural classification of loamy
				sand or finer, as determined by a Maine Certified Soil Scientist, may be placed
				on a septage land application site to meet the minimum depth-to-bedrock
				requirement. This fill material must be properly graded, seeded and mulched to
				prevent erosion.
D.
Suitable
				Soil Drainage Classes.
Septage land application sites may only be sited
				on the soil types which have drainage classes of: excessively-drained, somewhat
				excessively-drained; well-drained; moderately well-drained; or somewhat
				poorly-drained as determined by a Maine Certified Soil Scientist. All sand, or
				gravely soils which are excessively-drained must have a cap of loamy fine sand
				or finer soil which is at least twelve inches in thickness.
E.
Surface Slopes.
Ground
				surface slopes at any part of a site may not exceed eight (8)
				percent.
F.
Traffic.
The following design criteria must be met for all access roads to the site:
(1) On-site roads must be suitable for
				movement of traffic within the facility.
(2) Sight distances at road entrances to the
				facility must be suitable, as determined by one of the following:
(a) The sight distance to the entrance of the
				facility is equal to or greater than a foot value of ten (10) times the posted
				speed limit. Measurements are to be taken from the road entrance, ten (10) feet
				behind the edge of the shoulder and 42" off the ground, to a point down the
				road shoulder, 51" above the pavement; or
(b) The Department of Transportation has
				issued a permanent site entrance permit for the access road; or
(c) The local highway department has issued a
				permanent site entrance permit for the access road.
