REMEDIATION. REVIEW THE SURVEY REPORT. UNDERSTAND THE LIMITATIONS OF THE

SURVEY AND CONDUCT ADDITIONAL HAZARDOUS MATERIAL TESTING AS NEEDED.

2. ASSUME AND TREAT ALL PAINTED SURFACES AS LEAD-BASED PAINT (LBP). COMPLY

WITH THE REQUIREMENTS IN SECTION 02 83 00 LEAD REMEDIATION.

3. IF SUSPECT MATERIALS PREVIOUSLY UNFORESEEN BECOME UNCOVERED, TESTING

WILL BE REQUIRED PRIOR TO DISTURBANCE OF SUSPECTED MATERIALS. IN THE

ABSENCE OF TESTING, ASSUME THE MATERIAL CONTAINS HAZARDOUS SUBSTANCES,

AND DISTURB AND HANDLE IN A MANNER CONSISTENT WITH WORKING WITH KNOWN

HAZARDS.

CONTAMINATED SOIL MANAGEMENT:

1. CONDUCT CONTAMINATED SOIL WORK IN ACCORDANCE WITH 1) SECTION 02 61 13

EXCAVATION AND HANDLING OF CONTAMINATED MATERIAL AND 2) SOIL SCREENING

SURVEY FOR FY21 PN70551 CHILD DEVELOPMENT CENTER, ULRICH WAY, SCHOFIELD

BARRACKS, WAHIAWA.

2. THE SELECTED ACTION LEVELS ARE HAWAII DEPARTMENT OF HEALTH (DOH) TIER 1

BARRIER DELINEATING IMPACTED SOIL FROM CLEAN SOIL CAP OR HARSCAPE.

DOCUMENT LOCATIONS AND DEPTHS OF REUSED IMPACTED SOILS IN THE CLOSURE

REPORT.

5. MIXING OF CONTAMINATED SOIL WITH CLEAN SOIL IS NOT PERMITTED. CONTAMINATED

SOIL SHALL BE STOCKPILED SEPARATELY BASED ON THE LOCATION AND/OR TYPE OF

CONTAMINATION.

6. DESIGN AND IMPLEMENT ENGINEERING CONTROLS TO PREVENT THE RELEASE OF

CONTAMINATED SOIL DURING EARTHWORK.

7. EXCESS CLEAN AND CONTAMINATED SOIL THAT WILL BE TRANSPORTED OFF-BASE FOR

WITH FEDERAL, STATE, AND LOCAL LAWS AND REGULATIONS.

2. PROVIDE ALL NECESSARY SAMPLING AND TESTING FOR WASTE CHARACTERIZATION

AND PREPARE WASTE MANIFEST, WHEN APPLICABLE.

TREE LOCATION.

2. CUTTING OR TRIMMING OF ANY TREES OVER 15 FEET TALL IS PROHIBITED DURING THE

BAT PUPPING SEASON, 01 JUNE TO 15 SEPTEMBER. CONTACT UNITED STATES ARMY

GARRISON HAWAII (USAG-HI) NATURAL RESOURCES PROGRAM FOR GUIDANCE ON

TREES THAT MUST BE CUT DURING THE BAT PUPPING SEASON (E.G. EMERGENCY

SITUATION SUCH AS THREATENING POWER LINE). COMPLY WITH THE USAG-HI TREE

CUTTING MEMORANDUM, DATED 20 JANUARY 2017.

3. NO ACCUMULATION OF GREEN WASTE IS ALLOWED ONSITE, TO PREVENT INFESTATION

OF COCONUT RHINOCEROS BEETLE.

4. THE PROJECT SITE IS LOCATED IN AN AREA OF LOW POTENTIAL FOR ENCOUNTERING

ARCHAEOLOGICAL RESOURCES. SHOULD HUMAN REMAINS OR POTENTIAL

ARCHAEOLOGICAL ARTIFACTS BE DISCOVERED DURING THE PROJECT, ALL WORK IN
