8.6 ENVIRONMENTAL PROTECTION

A. Protection of Natural Resources: Comply with applicable regulations and these specifications.

Preserve the natural resources within the project boundaries and outside the limits of work performed under this Contract in their existing condition or restore to an equivalent or improved condition as approved by the COR.

B. Construction Zone: Arrange construction activities to minimize pollution (i.e., erosion, trash, etc.)

to the maximum practical extent.

1. Work zone is limited to the area described at the preconstruction meeting. A silt fence shall be installed around the work limits.

2. Clearing, excavation, and grading must be limited to those areas of the project site necessary for construction. Minimize the area exposed and unprotected.

3. Clearly mark and delineate the limits of work activities.

4. Equipment must not be allowed to operate outside the limits of work or to disturb existing vegetation.

5. Material must be stored away from locations where water is present to the greatest extent practicable.

6. All construction debris shall be contained and disposed of off the Park in a legal manner.

8.7 UNDER AN ACRE POLLUTION PREVENTION PLAN EXECUTION

A. Review and Acceptance: The Contractor and the COR will jointly review the draft Plan and agree to any needed revisions. The Contractor will incorporate all jointly agreed to revisions, and then sign and submit the final Plan to the COR. The final Plan will be the document enforced on the project.

1. The jointly agreed to Plan will describe and ensure implementation of the practices which will be used to reduce the pollutants in well water discharges and storm water discharges.

2. The Contractor must maintain a current copy of the Plan and all associated records and forms at the jobsite throughout the duration of the project.

GOGA – 334583 Division 1 Specifications - 15

3. The Plan must be available at all times for public inspection and for the inspection and use of the COR.

4. Concurrence by the COR to the jointly agreed to Plan will not relieve the Contractor of responsibility for compliance with other applicable environmental regulations.

B. Implementation: The Contractor must implement the Plan as required throughout the construction period and maintain all erosion control elements in proper working order.

1. Do not perform clearing and grubbing work until the Plan has been implemented.

8.8 SITE INSPECTIONS AND PLAN REVISIONS

A. Inspections: The Contractor and the COR (or authorized representative) will perform weekly inspections of the site.

1. The inspections will look at disturbed areas that have not been completely stabilized, areas used for storage of materials, locations where vehicles enter or exit the site, and all other erosion and sediment controls that are included in the Plan.

2. Inspections must be documented by the Contractor in their Contractor's Daily Quality Control Reports (CDQCR.)

3. Copies of the CDQCRs that include UPPP inspection information must be retained onsite in the Plan notebook throughout the construction period.

B. Plan Revisions: It may be necessary to revise the Plan during construction to make necessary improvements, revisions, or to respond to unforeseen conditions noted during construction or site inspections.

1. The Plan must specify the mechanism whereby revisions may be proposed by the Contractor or the COR.

2. The Contractor and the COR will jointly review each revision to the Plan before changes are incorporated and implemented. The Contractor will then provide a revised copy of the Plan to the COR.

3. Accepted modifications will be implemented within seven (7) calendar days following the date of the inspection when deficiencies or necessary corrections are first noted.

C. Negligence: Provide additional temporary erosion and pollution controls made necessary by Contractor's errors or negligence at no additional cost to the Government.

8.9 EROSION CONTROL MEASURES

A. Erosion control measures must consist of appropriate BMPs stream work and storm water discharges, including but not limited to silt fencing, barrier protectors, straw bales, wattles, temporary soil retention blankets, excelsior drainage filters, and sediment traps. Note: If straw bales are used locally purchased rice straw only is allowed to reduce chance of invasive species introduced to site.

GOGA – 334583 Division 1 Specifications - 16

B. Erosion control measures must be used to contain discharges within the construction zone. A sufficient area should be established to allow the discharged water to infiltrate into the native soil in such a manner that does not result in erosion of the natural ground surface.

C. All opportunities to facilitate the surface water to percolate into the ground must also be considered, such as utilizing sprinkler heads to evenly distribute the water or utilizing a diffuser pipe manifold and adequate vegetated flow paths.

D. Earthen barriers (non-jurisdictional dams) or holding ponds will not be authorized.

E. Precipitation runoff must be directed around and away from all fuel containment, storage, and work areas within the construction site boundary.

F. Divert precipitation runoff away from the worksite.

G. Construction water used for dust control must have a controlled application rate to prevent sheet flow within the project area as well as out from the construction boundary and into other areas of the Park.

H. Furnish, install, maintain, and operate necessary control measures and other equipment necessary to prevent erosion as described in the approved UPPP.

8.10 MAINTENANCE OF TEMPORARY FACILITIES

A. Ensure erosion and sediment control features remain effective throughout the test well work.

Maintain these features as necessary and reconfigure to adapt to changing conditions.

B. Continuously monitor erosion and sediment control features during test well development and pumping test. Inspect these features before and after each significant precipitation event.

Promptly repair weakened, damaged, and lost erosion and sediment control features.

8.11 REPORTING

A. If a discharge occurs or if the project receives a written notice or order from any regulatory agency, the Contractor will immediately notify the COR and will file a written report to the AHJ within seven (7) days of the discharge event, notice, or order. Corrective measures must be implemented immediately following the discharge, notice, or order. The report to the AHJ must contain the following items at a minimum:

1. The date, time, location, nature of operation, and type of discharge, including the cause or nature of the notice or order.

2. The BMPs deployed before the discharge event, or prior to receiving the notice or order.

3. The date of deployment and type of BMPs deployed after the discharge event, or after receiving the notice or order, including additional BMPs installed or planned to reduce or prevent re-occurrence.

4. An implementation and maintenance schedule for any affected BMPs.

8.12 SEDIMENT DISPOSAL

GOGA – 334583 Division 1 Specifications - 17

A. Sediment resulting from stormwater processes removed from temporary sediment control features must be disposed on the site within previously disturbed area at the end of the project as part of the site restoration. Sediment must be dried out prior to use in site restoration. The locations the sediment is applied must not be in areas susceptible precipitation runoff.

B. Sediment resulting from construction processes shall be removed from the site and disposed of in an acceptable manner.

8.13 REMOVAL OF TEMPORARY POLLUTION CONTROL MEASURES

A. All temporary control measures shall be removed with permission of the COR within ten (10) working days after final acceptance of the project, and/or once grading is completed, and slopes have stabilized.
