SEE NOTES NOTES: 1.EACH SITE MUST BE EVALUATED TO DETERMINE THE PROPER LAYOUT, WIDTH, AND DURATION OF THE INSTALLED TRACKOUT CONTROL SYSTEM (TCS) BASED ON SITE CONDITIONS, ENTRY AND EXIT LOCATION(S), TRAFFIC LEVELS, SITE SOIL CONDITIONS, AND ABILITY TO MAINTAIN THE TCS. 2.TCS SHALL BE INSTALLED, UTILIZED, AND MAINTAINED IN ACCORDANCE WITH MANUFACTURER RECOMMENDATIONS. 3.THE ENTRANCE SHALL BE MAINTAINED IN A CONDITION THAT WILL PREVENT TRACKING OR FLOWING OF SEDIMENT ONTO PUBLIC RIGHTS-OF-WAY. THIS MAY REQUIRE SUPPLEMENTAL TOP DRESSING, REPAIR, AND/OR CLEANOUT OF ANY MEASURES USED TO TRAP SEDIMENT. 4.WHEN NECESSARY, WHEELS SHALL BE CLEANED PRIOR TO ENTRANCE ONTO PUBLIC RIGHT-OF-WAY. 5.TCS MATS SHOULD BE CLEANED ONCE TWO-AND-A-HALF INCHES (2.5") OF SEDIMENT HAS BUILT UP ON THE LANE OF TRAVEL. 6.CAUTION IS TO BE USED WHEN CROSSING MATS WITH METAL TRACKED EQUIPMENT. EQUIPMENT WITH AGGRESSIVE METAL TRACKS SHOULD NOT CROSS MATS. 7.DO NOT USE MATS FOR BRIDGING.
