The CO or COR shall inspect by validating actual work performance, physically checking an attribute of the completed task, checking a management information report, investigating customer complaints, conferring with facility managers, or otherwise inspecting the task or its results to determine whether or not performance meets the standards contained in this PWS. The CO or COR shall use the contractor’s work schedule or modified version thereof, to record validation results. Results of the validation then become the official Air Force record of the contractor’s performance. When a performance threshold has not been met or contractor performance has not been accomplished, the COR shall initiate and provide the CO a Contract Discrepancy Report (CDR) DD Form 2772 for issuance to the contractor. The contractor shall respond to the CDR IAW instructions provided and return it to the CO within one (1) calendar day of receipt.

4 GENERAL INFORMATION

4.1 MISSION

The overall Civil Engineer mission at Homestead ARB is to plan, maintain, operate, and protect the infrastructure, facilities, and environment for assigned airmen, families, and civilian employees.

4.2 BACKGROUND

HARB is in the Southern Florida Coastal Plain ecoregion, which covers an area of approximately 22,407 square kilometers (km2) (8,651 square miles [mi2]) across the lower portion of the Florida peninsula, from Lake Okeechobee south to the Florida Keys. It consists of flat plains with wet soils, marshland and swamp land cover with everglades and palmetto prairie vegetation types. Due to this region specialized marsh and wetland grounds maintenance equipment is required.

The environment of this ecoregion is generally nutrient-poor, particularly in the Everglades, which has historically been subject to runoff from urban and agricultural sources, leading to changes in habitat health and diversity. Surface water levels and sheet flow in the Everglades are sensitive to differences in topography. The ecoregion is large and features a flat terrain, with changes of only a few centimeters in elevation; this can have significant impacts on types of plant and animal communities present.

4.3 DAMAGES TO GOVERNMENT BUILDINGS, EQUIPMENT, OR VEGETATION

Damages to Government buildings, equipment, or vegetation are addressed in clause 52.237-2 – “Protection of Government Buildings, Equipment, and Vegetation.”

4.4 ENVIRONMENTAL REQUIREMENTS

In addition to all applicable Federal, State and local environmental codes and regulations, the following specific guidance is provided:

Currently, the USACE regulates wetlands under Section 404 of the Federal Water Pollution Control Act Amendments of 1972 to the CWA. Jurisdictional wetlands are defined by the USACE as “…those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and other areas.” (USACE, 1987).

Natural resource management practices on HARB are designed to meet regulatory requirements and foster sound stewardship of natural resources within the constraints of military mission requirements and BASH and other safety concerns. The primary environmental management issues on HARB include:

• Protecting and maintaining wetland functions

• Restoring pine rockland habitat without using fire

• Controlling/eradicating invasive/exotic species

• Managing water quality

• Maintaining and enhancing natural habitat values and ecosystem functions

4.4.1 HAZARDOUS MATERIALS

The CO shall approve all hazardous materials after approval from CEV (Civil Engineer Environmental office) brought on-site by the contractor prior to use.

Once the process is implemented and contractor is trained, the contractor may submit the AF3952 electronically. The CO with recommendation of CEV has the right to prohibit the use of hazardous materials it deems to be especially hazardous to human health and environment. In the event the CO with recommendation of CEV does not approve a hazardous material for use, the CO with recommendation of CEV may provide the contractor a list of suitable substitutes; however, the contractor shall retain responsibility for finding an acceptable substitute.
