Hangar 7 - Remove Paint Booth Ventilation System

1. SCOPE OF WORK:

Historic painting, sanding and corrosion control activities for aircraft has led to the accumulation of heavy metals (Cadmium, Chromium and Lead) within settled dust and overspray throughout the subject structure.

This area has been cleaned, however there is remaining dust and particulates within the previous paint filtration ventilation system. The purpose of this project is to carefully remove and dispose of the previously used ventilation system that was a part of the paint spraying operation, while being cautious to capture any contamination that may be released in the process. Up to two wipe downs and decontaminations may be required as part of the statement of work.

The contractor shall provide all personnel, equipment, tools, materials, supervision, transportation, and other items and services necessary to complete the work as described in this Statement of Work (SOW).

Work location is Building 7 at the 109th Airlift Wing (109 AW), 1 Air National Guard Road, Scotia New York 12302.

2. AREA OF WORK:

Contractor shall work only in the areas designated by Contracting Officer Representative (COR). Hangar 7, the former Corrosion Control Facility (Paint Booth), is the location for this work. A floor plan of the work area is included as Attachment A.

3. DESCRIPTION OF WORK:

3.1. The work specified by this section consists of furnishing all labor, equipment, tools, appliances, transportation, materials, and quality control reports required to remove contaminated ductwork and ventilation system, and to fully remediate any hazardous levels of cadmium, chromium and lead identified within the work area. These areas include but are not limited to the former paint booth area, paint storage area, paint mixing room, abrasive blast room, and tool room. Rooms are identified on floor plan included in Attachment A. All work must be completed without damage to any government property.

3.2. All work performed under this SOW shall be conducted in accordance with all applicable state and federal laws and regulations, ANG policies and regulations, and this SOW as outlined below.

3.3. Removal of all dust/overspray accumulation from all surfaces within the work area utilizing wet wipe/scraping methods and HEPA vacuum methodologies. This includes a thorough decontamination of fixtures, walls, ceilings, floor, structural members and drain surfaces. Any water accumulation as part of the cleaning process must be treated (filtered to remove all contaminates), tested and approved by the Base prior to discharge.

3.4. Contractor shall remove and dismantle all “paint booth” and “abrasive blast” ventilation and exhaust equipment and components (fans, filters, etc..) along with associated duct work located within the Building 7 former Corrosion Control Facility (CCF) with the exception of the current roof top units HV- 21 and HV-22 and associated ductwork that supply heat to the area. All ductwork associated with HV-23 is to be decontaminated and removed from within the CCF. If unable to decontaminate ductwork onsite, all contaminated ductwork is to be characterized through representative lab sampling (TCLP), containerized and handled appropriately, potentially as hazardous waste.

Attachment B displays the original plans to scale for the CCF area. Length of ductwork and size can be calculated from this attachment. The HV units were moved to the rooftop approximately 10 years ago, however are shown in their original location on Attachment B.

3.4.1. Supply Air Paint Booth System – Twin supply ductwork, as shown below, is to be removed.

Material removed from the supply air system is anticipated to be non-hazardous and should be isolated from all exhaust materials removed. Material to be recycled by Contractor. All recycling documentation and/or disposal records are to be supplied to the COR and the Base Environmental Manager.

3.4.2. Exhaust Air Paint Booth Ductwork – The previous filter wall has three exhaust outlets, and corresponding ductwork. The residue within the exhaust system is anticipated to be hazardous and all dust is to be controlled during removal of the ductwork. Any residual dust in Paint Room is to be cleaned with both a Hepavac, and wet method, and then surrounding walls and floors are to be tested utilizing swipe test as described in Section 3.11. All exhaust ductwork is to be removed up until the hangar wall penetration is reached, approximately 50 feet away from the filter wall outlet connection.

Contractor to use either a site visit or plans to confirm actual distance and amount of ductwork to be removed. At this project end point for each duct, Contractor is to seal off the wall (and/or roof penetration) to matching conditions, per Section 3.6. Hangar wall repairs are to be 2 hr fire rated. Roof penetrations are to be insulated (2” board), and then capped with galvanized sheet metal, taped and sealed with a weather proof material approved by COR. Proposed materials and methods are to be submitted to the COR for approval in advance of performing the seal.

The exhaust ductwork was tested and analytical was performed for the toxicity characteristic leaching procedure (TCLP). Results are included in Attachment C, page 5. It is anticipated that the exhaust ductwork will be characterized as hazardous waste due to the paint particulate that has settled within.

Red = Three exhaust lines from previous filter wall. Each line is to be completely removed back to the hangar wall and/or roof penetration. Top of filter casing (horizontal), along with any filter structures that remain are also to be removed. Note: this is elevated work and contractor required to provide their own lift.

3.4.3 Abrasive Blast Ductwork – The abrasive blast room also requires removal of an exhaust system.

Ducts to be removed from floor level to first penetration with roof and/or hangar wall. Penetrations to be sealed per SOW.
