continuous process from project start-up to final acceptance of the Work by the Engineer. PART 2 PRODUCTS 2.01 GENERAL CLEANUP A. Cleanup shall include the regrading, resurfacing, rebuilding
and replacing of all surfaces on which construction took place, and rebuilding or replacing any areas disturbed by the construction. The streets or roads where disturbed shall be resurfaced
by the Contractor, including both gravel and oil roads, and shall be replaced in as good or better condition than that at the start of construction. The Engineer shall be the sole judge
as to whether streets, roads or property have been restored to a condition as good or better than at the start of construction. B. The Contractor shall, at all times, keep property on
which Work is in progress free from accumulation of waste material or rubbish caused by employees or caused by the Work, and he shall carry on a constant program to maintain Work area,
structure sites, right-of-ways and the surface of streets and roads in a condition satisfactory to the appropriate authority, grantor of the right-of-way, and the Engineer. C. Preliminary
cleanup shall commence as soon as the construction site is occupied by the Contractor (including his employees, supplies, materials or equipment) and shall be a continuous process, if
necessary, in order that the site of the Work shall have an appearance and/or utility equal to or better than the start of the Work. D. Upon completion of the Work, the Contractor shall
remove all remaining rubbish, tools, equipment, scaffolds and surplus materials from the job and leave the Work area clean and free of debris. 02700 Finished Grading and Restoration.doc

SECTION 02822 TEMPORARY EROSION CONTROL PART 1 GENERAL 1.01 SUMMARY A. This work consists of furnishing and applying soil binding slurry over disturbed slopes as a temporary soil erosion
inhibitor. Disturbed slopes that will not be reworked and finished slopes that are not scheduled revegetation for a period 21 days or more shall be treated as construction progresses.
As construction progresses into the Fall season, all disturbed slopes that will not be re-worked before spring and finished slopes that are not scheduled for revegetation until spring
shall be treated before the onset of winter and far enough in advance, in order for the treatment to be applied in accordance of the climatic requirements of this specification. Contractor
shall furnish the equipment and labor necessary for performing the work. B. Soil binding agent shall be applied to all disturbed open slopes using standard mechanized hydraulic equipment
used for broadcasting water based slurry products. C. The soil-binding agent shall be added to the proportionate quantity of water and thoroughly mixed per manufacturer's recommendations.
D. This specification shall apply to all disturbed areas outside CDOT right-of-way. PART 2 PRODUCTS 2.01 MATERIALS A. Soil binder shall be Soil Master WR or approved equal. Soil binder
shall be nontoxic, non-flammable and conform to the following properties: Copolymer of methacrylates/acrylates/acrylics/tripolycate Extgoxylated surfactants Silicates Inert ingredients
pH Color Lbs. per U.S. gallon 60% 2% 2% 36% 4 -5.1 Milky white 9 -10 Ibs. B. Wood cellulose fiber mulch shall be Mat-Fiber, or approved equal. Wood cellulose fiber mulch shall conform
to the following requirements: Moisture content (total weight basis) Organic matter (oven-dried weight basis, min.) Inorganic content (oven-dried weight basis, max.) 02822 Temporary

pH at 3% consistency in water slurry (avg.) 4.9 Water holding capacity (min.) Color 1.2 gal/lb. Green C. Water used for establishing the proper dilution ratio shall be clean, free of
sediment and other debris and pollutants. 2.02 OTHER ACCEPTED DUST SUPPRESSION ADDITIVES A. Starch-Based or other 100% Natural Polymer 1. Accepted Product -DustStar by Chemstar or approved
equal. PART 3 EXECUTION 3.01 CONSTRUCTION REQUIREMENTS A. Liquefied soil binder (Soil Master WR) shall be thoroughly mixed with water and wood cellulose fiber mulch (Mat-Fiber) into
a homogeneous mix and applied to the disturbed ground at the following rate per acre: Soil Binder/Acre Cellulose Fiber/Acre Water/Acre 165 gallons 200 pounds 2,000 gallons B. The soil-binding
product and cellulose fiber mulch shall be slowly poured into the slurry tank with agitators activated until a homogeneous slurry is formed. The soil binding slurry shall be applied
when the ground temperature is fifty degrees F. or greater at time of application and sustained while the slurry solidifies and stabilizes for a forty-eight hour period. C. The soil
binding slurry shall be sprayed uniformly over the disturbed areas. Application shall be in the form of a mist and avoid over saturation that results in the slurry running off the slope.
Contractor may need to spray areas more than once to achieve the proper coverage and avoid over-saturation. The slurry shall be applied to a moistened ground, but not in the presence
of freestanding surface water. Any areas not sealed with the soil binder properly or areas damaged due to the negligence of the Contractor shall be repair and retreated. D. The Engineer
may order test sections be established for adjusting the equipment and assure proper application and conformance to the specification. END OF SECTION 02822 Temporary Erosion Control.doc
