The following requirements shall be met on all sites:
(A) Sediment-laden water flowing from the site shall be detained by temporary sediment basins. Also, water shall not be discharged in a manner that causes erosion in the receiving channel.
(B) Wastes or unused building materials, including but not limited to garbage, debris, cleaning wastes, waste water, toxic materials and hazardous substances, shall not be carried by runoff from a site. Proper disposal of all wastes and unused building materials, in line with the nature of the waste or material, is required.
(C) Sediment being tracked from a site onto public or private roadways shall be minimized. This can be accomplished initially by a well planned layout of roads, access drives and parking areas of sufficient width and length. However, protective covering also may be necessary.
(D) Public or private roadways shall be kept cleared of accumulated sediment. If appreciable sedimentation occurs after a storm event, the sediment shall be deposited on the parcels of land, if in the site, from where it likely originated.
(E) All storm drain inlets shall be protected against sedimentation with straw bales, filter fabric, or equivalent barriers meeting accepted design criteria, standards, and specifications.
(F) The following items apply only to the time period when land disturbing activities are taking place:
(1) Runoff passing through a site from adjacent areas shall be controlled by diverting it around disturbed areas. Alternatively, the existing channel may be improved to prevent erosion or sedimentation from occurring.
(2) Runoff from a disturbed area shall be controlled by one or more of the following measures:
(a) Barring unforeseeable weather conditions, all disturbed ground left inactive for seven or more days shall be stabilized by seeding, sodding, mulching, covering or by other equivalent erosion control measures.
(b) With disturbed areas within a site of less than ten acres, filter fences, straw bales, or equivalent erosion control measures, placed along all sideslope and downslope sides of the site, shall be required. Also, if concentrated runoff passes through the site, filter fences shall be placed along the edges of the concentrated flow area to reduce the amount of sediment removed from the site. However, if these measures are not sufficient to control off-site sedimentation, a sediment basin may still be required.
(3) Erosion from all soil storage piles shall be controlled by placing straw bales, a filter fence or other appropriate barriers around the piles. Adjacent storm drain inlets shall be protected using similar filter barriers. Moreover, any soil storage pile containing more than ten cubic yards of material shall be located at least 25 feet upslope from a roadway or a drainage channel. Furthermore, if remaining in existence for more than seven days, the storage pile shall be stabilized by mulching, vegetative cover, tarps or other means. Storage piles containing less than ten cubic yards of material may be located closer than 25 feet to a roadway or a drainage channel, but shall be covered with tarps or a suitable alternative if in existence for less than seven days. However, if a pile is in existence for more than seven days, barriers also shall be placed around the pile.
