About this file
This document contains questions and answers regarding a solicitation for a roof replacement project at a Federal Aviation Administration facility in King Salmon, Alaska. The solicitation seeks a firm-fixed price contract to remove and dispose of an existing roof and materials, including terne metal counterpoise coated with lead-based paint containing PCBs. Test reports confirm PCB levels above recycling thresholds, so the intent is for the contractor to dispose of the materials as hazardous waste, which could make the FAA a one-time large quantity generator. Bidders sought clarification on waste characterization and disposal processes given the hazardous materials involved. The response provides the requested test reports and confirms the materials should be treated and disposed of as RCRA hazardous wastes.

6973GH-20-R-00061 King Salmon, Alaska Questions
In an effort to accurately bid the following scopes of work at AKN VOR-King Salmon, we respectfully request clarification of the FAA intent regarding the following materials waste characterizations and disposal processes:
· Spec section 01110-3 #13 states “Remove and dispose of existing roofing membranes, terne metal counterpoise, metal fascia, fasteners, and plywood down to T&G wood decking. Existing terne metal counterpoise is coated with lead. Orange paint on terne metal counterpoise and teepee base flashing contains lead and PCB’s…terne metal is coated with lead…lead coated counterpoise shall be pried from wood decking without disturbing the lead or asbestos mastic…”
· QUESTION: Please clarify this sentence as referring to terne metal and it should not refer to counterpoise metal?
The existing roof counterpoise is made of terne metal. The terne metal is basically lead coated steel sheeting. The terne metal is painted with an orange colored lead based paint. The orange colored lead based paint contains PCB’s.
· Spec section 01110-6 #1.5 states “test reports are available upon request”
· QUESTION: Please provide reports of PCB and LEAD parts per million to accurately determine cost of waste and disposal processes. Please see next question as it relates to test reports.
See attached Lead and PCB test reports.
· Spec section 01110-7 Hazardous Waste / Generator Status “Contractor shall attempt to maintain FAA VSQG. In the event there is no way to avoid LQG status, Contractor shall provide all administrative and physical requirements for LQG until wastes are shipped off site.”
· QUESTION: is the terne metal material anticipated to be over or under the hazmat classification limits for RCRA waste? Please provide test reports for all demolition related metals anticipated to contain Lead and PCB.
Based on generator knowledge, assume paint and terne metal are RCRA wastes for shipping and disposal.
See attached Lead and PCB test reports.
· QUESTIONS: Does the FAA intend for contractor to recycle the lead/pcb coated metal? If so, does FAA intend to have contractor remove the lead and pcb from the metal? Or does FAA intend for contractor to dispose of hazmat coated metal?
The concentration of PCB’s in the paint on the terne metal are above the level permitted for recycling the metal. Theoretically the contractor could remove the PCB containing paint and recycle the terne metal, but this is not recommended nor encouraged. Original intent was to dispose of the painted terne metal as a RCRA waste realizing this could make the FAA a one-time LGQ generator.
