DISPLACEMENT CEASES.

2. AGGREGATE BASE SHALL BE PLACED IN SUCH A MANNER AND TO

SUCH DEPTH THAT, WHEN COMPACTED, IT WILL CONFORM TO THE

GRADES AND SECTIONS SHOWN ON THE PLANS. DO NOT PLACE

AGGREGATE IN LAYERS EXCEEDING 6” COMPACTED THICKNESS.

3. AGGREGATE BASE SHALL BE COMPACTED WITH A VIBRATORY

COMPACTOR. COMPACT A MINIMUM OF THREE PASSES OR UNTIL

VISUAL DISPLACEMENT OF EACH LAYER CEASES. ADD WATER AS

REQUIRED TO ACHIEVE REQUIRED COMPACTION.

GENERAL NOTES:

CONCRETE CONTAINMENT AREA, IDENTIFIED AS "NIC" (NOT IN CONTRACT),

WILL BE INSTALLED BY OTHERS (WCJC CONCRETE TRADE, OR FUTURE

CONTRACT) WITH EXPECTED IMPLEMENTATION BY SEPTEMBER 2013.

TEMPORARY CONTAINMENT AREA WILL BE INSTALLED UNDER THIS

CONTRACT MODIFICATION, SEE SHEET C-4 FOR DETAILS.

TEMPORARY CONTAINMENT AREA SHALL ROUGHLY MATCH THE

DIMENSIONS OF THE PERMANENT CONTAINMENT FACILITY

DEPICTED ON THESE DRAWINGS.

CONTAINMENT SHALL COMPLY WITH NPDES PERMIT SCHEDULE F,

SECTION B.9 WHICH STATES, "SOLIDS, SLUDGES, FILTER

BACKWASH, OR OTHER POLLUTANTS REMOVED IN THE COURSE

OF TREATMENT OR CONTROL OF WASTEWATERS MUST BE

DISPOSED OF IN SUCH A MANNER AS TO PREVENT ANY

POLLUTANT FROM SUCH MATERIALS FROM ENTERING WATERS

OF THE STATE, CAUSING NUISANCE CONDITIONS, OR CREATING

A PUBLIC HEALTH HAZARD."
