• 4.03.1(3) Tert~orary erosion control ~++Aa~~res (ditches, straw dikes)
(d) (x) shall be implemented durirsg ernbarilanent construction to
m;n;m;ze ~i~++Pntation and erosion until permanent control
measures can be established. Irmrediately upon conq~letion,
~a~n-es will be taken to stabilize all embanla[~~ts with
vegetation Dover or other means as approved by the Division to
m;n;m;ze erosion. 4Riere a vegetation cover is used,
consideration shall be given to providing an appropriate
growth medium.
4.03.1(3) Topsoil aryl other material as determined order 4.06.2 will be
(d)(xi) removed frcun the design roadbed, shoulders, and surfaces where
associated structures will be placed, and will be stored in
accordance with 4.06.3.
4.03.1(4) Drainage. Each haul road not within estimated disturbance
• (b)(e) areas (see F~diibit 12-1) will be designed, constructed, aryl
maintained to have adequate drainage using ditches and
culverts to safely convey the peak runoff frmn a 10-year,
24-hour precipitation event to sediment ponds before being
released off the permitted area (see FSd~ibit 7-7 for general
locations and ESdiibit 7-14 for typical details of drainage
structtn-es and Attachment 7-6-4 for design details of ditch
types A, B, and D).
Drainage ditches will be placed at the toe of all cut slopes
formed by the construction of haul roads. Water will be
intercepted before reaching a switchback or large fill aryl
drained safely away in accordance with the requirements of
4.03.1. Water from a fill or switchback fill be released
below the fill through conduits or in riprapped channels aryl
will not be dischan~ed onto the fill. In order to more
effectively protect the slopes below haul roads and access
• roads, Seneca proposes to utilize alternative specifications
for culvert spacing as allowed for in Rule 4, Part
4.03.1(4)(e)(vi). Ditch relief cross drains will not be
