a. Grass hay bales are not acceptable.

b. In order to prevent deterioration of the bindings, all bales shall be either wire-bound or string-tied so that bindings are oriented around the sides rather than along the tops and bottoms of the bales.

PART 3 - EXECUTION

3.1 CONSTRUCTION

A. Install straw bales at local drainage ways to prevent silt intrusion upon adjacent drainage courses. Remove straw bales following establishment of vegetation cover and utilize as mulch at swales or on steep slopes.

B. Prior to construction, install silt fence along the downhill construction limits to prevent silt intrusion upon adjacent land.

C. Install sediment and erosion control measures on the down slope toe of all topsoil stock piles.

D. Maintain and remove all erosion controls as specified.

3.2 DUST CONTROL

A. In areas subject to surface and air movement of dust, where on-site or off-site damage is likely to occur, one or more of the following preventive measures shall be taken for dust control:

SEDIMENT AND EROSION CONTROL MEASURES 023701-3

1. Minimize the period of soil exposure through the use of temporary ground cover and other temporary stabilization practices.

2. Sprinkle the site with water until surface is wet. Repeat as needed.

3.3 SILT FENCE

A. Silt fences are appropriate for the following general locations:

1. Immediately upstream of the point(s) of runoff discharge from a site before flow becomes concentrated. Below disturbed areas where runoff may occur in the form of overland flow.

2. Along the down slope toe of all topsoil stock piles.

B. Materials.

1. Utilize standard strength synthetic filter fabric for sediment barriers. The filter fabric shall be purchased in a continuous roll cut to the length of the barrier to avoid the use of joints. When joints are necessary, filter cloth shall be spliced together only at a support post, with a minimum 6 inch overlap, and securely sealed.

2. The standard strength filter fabric shall be stapled or wired to the fence and 6 inches of the fabric shall be extended into the ground. Filter fabric shall not be stapled to existing trees.

3. Support posts shall be spaced at a maximum 6 feet and driven securely into the ground a minimum of 24 inches.

4. Filter fabric shall be buried a minimum of 12 inches.

5. The height of a silt fence shall not exceed 36 inches. Higher fences may impound volumes of water sufficient to cause failure of the structure.

C. Maintenance.

1. Silt fences and filter barriers shall be inspected immediately after each rainfall and at least daily during prolonged rainfall.

2. Silt fences shall be inspected for depth of sediment, tears, and to see if the fabric is securely attached to the fence posts, and to see that the fence posts are firmly in the ground. Any deficiencies shall be repaired immediately.

3. Should the fabric on a silt fence of filter barrier decompose or become ineffective prior to the end of the expected usable life and the barrier still be necessary, the fabric shall be replaced promptly.

4. Sediment deposits should be removed after each storm event and/or when deposits reach approximately 1/3 the height of the barrier or when the sediments limit or prevent the flow of water through the fabric hydraulic.

5. Any sediment deposits remaining in place after the silt fence or filter barrier is no longer required shall be dressed to conform with the existing grade, prepared, and seeded.

3.4 STRAW BALE EROSION CONTROL FENCE

A. Straw bale erosion control fences are appropriate for the following general locations:

SEDIMENT AND EROSION CONTROL MEASURES 023701-4

1. Sheet flow applications: Straw bales shall be placed in a single row, lengthwise on the contour with ends of adjacent bales tightly abutting one another.

2. Channel flow applications: Straw bales shall be placed in a single row, lengthwise and oriented perpendicular to the direction of flow with ends of adjacent bales tightly abutting one another. The barrier shall be extended to such a length that the bottoms of the end bales are higher in elevation than the top of the lowest middle bale to assure that sediment laden runoff will flow either through or over the barrier but not around it.

B. The barrier shall be entrenched and backfilled. A trench shall be excavated the width of a bale and the length of the proposed barrier to a minimum depth of 4 inches. After the bales are staked and chinked, the excavated soil shall be backfilled against the barrier.

Backfill shall conform to the ground level of the downhill side and shall be built up to 4 inches against the uphill side of the barrier.

C. Each bale shall be securely anchored by at least 2 stakes or rebar driven through the bale.

The first stake in each bale shall be driven toward the previously laid bale to force the bales together. Stakes or rebar shall be driven a minimum of 12 inches into the ground or deep enough into the ground to securely anchor the bales, whichever is greater.

D. The gaps between bales shall be chinked (filled by wedging with straw to prevent water from escaping between the bales). Loose straw scattered over the area immediately uphill from a straw bale barrier tends to increase barrier efficiency.

3.5 MAINTENANCE

A. Inspection shall be frequent and repair or replacement shall be made promptly as needed.

Straw bale carriers shall be removed when they have served their usefulness, but not before the upslope areas have been permanently stabilized.
