COURSE OF ACTION. THE CONTRACTOR IS RESPONSIBLE FOR ADHERENCE TO THE

NPDES PERMIT AND SHALL UPDATE THE STORM WATER POLLUTION PREVENTION

PLAN PER SPECIFICATION 01 57 20.00 25 - ENVIRONMENT PROTECTION.

FILTER FABRIC FENCE:

1. FILTER FABRIC SHALL BE A CONTINUOUS ROLL CUT TO LENGTH OF BARRIER AS

NEEDED. IF JOINTS ARE NECESSARY, FABRIC SHALL BE SPLICED TOGETHER ONLY

AT SUPPORT POSTS WITH A MINIMUM OF SIX (6) INCH OVERLAP. BOTH ENDS SHALL

BE SECURED AS REQUIRED.

2. FILTER FABRIC SHALL BE INSTALLED TO FOLLOW CONTOURS.

3. A TRENCH SHALL BE EXCAVATED, ROUGHLY EIGHT (8) INCHES WIDE BY EIGHT (8)

INCHES DEEP UPSLOPE AND ADJACENT TO THE POSTS TO ALLOW THE FILTER

FABRIC TO BE BURIED.

4. ALL FENCING SHALL BE INSPECTED WEEKY DURING CONSTRUCTION AND AFTER

EACH SIGNIFICANT RAINFALL EVENT UNTIL SITE HAS BEEN PERMANENTLY

STABILIZED. ANY REQUIRED REPAIRS SHALL BE MADE IMMEDIATELY.

5. REMOVAL OF TRAPPED SEDIMENT SHALL BE PERFORMED WHEN AMOUNTS REACH

APPROXIMATELY 1/3 HEIGHT OF THE FENCE.

6. FILTER FENCING SHALL REMAIN IN-PLACE UNTIL SITE HAS BEEN REVEGETATED OR

AS DIRECTED BY COR. CONTRACTOR SHALL BE RESPONSIBLE FOR FENCING

REMOVAL FROM THE SITE WITHIN 30 DAYS OF SITE STABILIZATION.

SAND FENCE:

1. INSTALL SAND FENCE IN THE PRIMARY STAGING AREA, MATERIAL OFFLOAD

STAGING AREA, AND JETTY ROOT STAGING AREAS WHEN NOT USED FOR STAGING

OR STOCKPILING OF JETTY STONES OR EQUIPMENT FOR PERIODS GREATER THAN 3

MONTHS BETWEEN MAY AND OCTOBER.

2. INSTALL SAND FENCE IN THE STAGING AREAS AT THE END OF CONSTRUCTION

ACTIVITIES AS PART OF THE SITE RESTORATION ACTIVITIES. SEE LS101 AND

SECTION 32 31 29.13 25 SAND FENCING.

CONSTRUCTION ENTRANCES:

1. QUARRY SPALLS SHALL BE IN-PLACE AND FUNCTIONAL BEFORE SITE PREPARATION

ACTIVITIES COMMENCE. ANY DEBRIS TRACKING ONTO ADJACENT ROADWAYS

SHALL BE CLEARED DAILY. AT NO TIME SHALL ONLY WATER BE PLACED ON
