1. CONDITIONS OF USE
1.1. PLASTIC COVERING MAY BE USED ON DISTURBED AREAS THAT REQUIRE COVER MEASURES FOR LESS THAN 30 DAYS.
1.2. PLASTIC IS PARTICULARLY USEFUL FOR PROTECTING CUT AND FILL SLOPES AND STOCKPILES.
1.3. CLEAR PLASTIC SHEETING MAY BE USED OVER NEWLY -SEEDED AREAS TO CREATE A GREENHOUSE EFFECT AND ENCOURAGE GRASS GROWTH.
CLEAR PLASTIC SHOULD NOT BE USED FOR THIS PURPOSE DURING THE SUMMER MONTHS.
1.4. THIS METHOD SHALL NOT BE USED UPSLOPE OF AREAS THAT MIGHT BE ADVERSELY IMPACTED BY RUNOFF. SUCH AREAS INCLUDE STEEP AND
UNSTABLE SLOPES.
2. DESIGN AND INSTALLATION SPECIFICATIONS
2.1. PLASTIC SHEETING SHOULD HAVE A MINIMUM THICKNESS OF 0.06 MILLIMETERS.
2.2. IF EROSION AT THE TOE OF A SLOPE IS LIKELY, A GRAVEL BERM, RIPRAP, OR OTHER SUITABLE PROTECTION SHALL BE INSTALLED AT THE TOE
OF THE SLOPE IN ORDER TO REDUCE THE VELOCITY OF RUNOFF.
2.3. TIRES, SAND BAGS, OR EQUIVALENT MAY BE USED TO WEIGHT PLASTIC.
2.4. SEAMS BETWEEN SHEETS MUST OVERLAP A MINIMUM OF 12 INCHES AND BE WEIGHTED OR TAPED.
3. MAINTENANCE STANDARDS
3.1. TORN SHEETS MUST BE REPLACED AND OPEN SEAMS REPAIRED.
3.2. IF THE PLASTIC BEGINS TO DETERIORATE DUE TO ULTRAVIOLET RADIATION, IT MUST BE COMPLETELY REMOVED AND REPLACED
3.3. WHEN THE PLASTIC IS NO LONGER NEEDED, IT SHALL BE COMPLETELY REMOVED.
