Protection of Sensitive and Endangered Species Refer to the attachment Biological Assessment for Federally Listed Species and Critical Habitat for Pisgah National Forest in full for guidance with attention to Appendix A for special considerations. Endangered Species Act (ESA) requirements during culvert replacement also include the following:

1. General Identification and Avoidance: The Government has identified protected plant and animal species within the project vicinity. The Contractor shall restrict all ground-disturbing activities, equipment staging, and material storage to the designated areas.

2. Physical Protection Measures Flagging and Fencing: The Contractor shall maintain all Government-installed flagging or orange construction fencing. If any flagging or fencing is damaged or removed, the Contractor must stop work in that immediate area and notify the Contracting Officer Representative (COR) for replacement. No-Entry Zones: Areas shall be flagged to represent "No-Entry" zones for personnel and equipment. No soil, debris, or equipment shall be pushed into or stored within these zones. Contact COR when entry into these areas are unavoidable to discuss potential options.

3. Mitigation and Best Management Practices (BMPs) Erosion Control: Since the project involves upsizing culverts on a slope, the Contractor must use weed-free certified straw wattles or silt fencing to prevent sediment runoff from entering sensitive habitat or downstream reaches. Invasive Species Prevention: To protect native plant species, all heavy equipment must be pressure-washed and inspected for weed seeds and soil before entering National Forest System lands. Pollution Prevention: All refueling must occur at least 100 feet away from the drainage inlet and sensitive plant zones. All heavy equipment (excavators, loaders) must be inspected daily for hydraulic or fuel leaks. Any equipment found leaking must be removed from the project site immediately.

8.0 Quality Control Plan

The Contractor shall submit to the CO, a Quality Control Plan (QCP) as part of their proposal that will detail the methods the Contractor will use to perform self-inspection to ensure the requirements of this contract are performed in accordance with the contract documents. The QCP shall at a minimum record the reference pay item, location, frequency, type of test and resulting outcome. QCPs shall be submitted with the Accomplishment Report and no payment will be made prior to receipt of these records and acceptance of the work performed.

At a minimum, the QCP shall contain:

Inspection System. An inspection system must cover all of the services listed in the contract documents. It must specify the work items to be inspected on either a scheduled or unscheduled basis, how often inspections will be accomplished, and the title of the individual(s) who will perform the inspection. The inspection system must provide for a written record of inspections and results.

Methods. Identify the proposed methods for identifying and preventing defects before the level of performance becomes unacceptable.

Records. The contractor shall maintain on-site records of all inspections and necessary corrective action(s) taken. This documentation shall be furnished at the time payment is requested, or when requested by the Contracting Officer’s Representative during the term of the contract. Project inspectors reserve the right to check contractor’s Quality Control Inspections at any time during the life of the project.

9.0 Government Quality Assurance

The Government will monitor progress to ensure that the Contractor is providing the quality promised in their QC Plan and that work meets performance standards. Visual observation may be used. The Government reserves the right, if deemed necessary to ensure compliance with the contract, to make random or 100% full inspections of the work. Each road and culvert will be inspected separately.

Government inspections will be documented on Daily Diaries and placed in the contract file. If work in part of an area is not acceptable, a Notice of Non-Compliance will be issued to the Contractor. See attached for sample of form. The CO may issue other cure notices if work is not being performed in a timely manner or does not comply with contract specifications.

Upon completion of a culvert or road and notification by the Contractor, the COR or designated Inspector shall make an overall inspection of that/those culverts/roads.
