1.0 PURPOSE

The purpose of this modification is to remove asbestos in overhead evaporator heater units, clean the evaporator coil, modify the condensate drainage system to 1” ID hoses, and install a new small drain pan to capture condensate from the expansion valve to coil piping.

The modification calls for certified contractor removal of accessible asbestos gaskets to eliminate potential future issues. Asbestos will be removed at the drain pan heater box interface, the heater box lower access cover interface, and the insulator mounting block locations. Evaporator coils will be cleaned while drain pans are down to allow a more thorough cleaning and improve heat transfer to the coils. The drain modification opens up the drain tubes to 1” ID and allows condensate moisture to easily drain out the bottom of the railcar without plugging up from debris. The expansion valve drain pan mirrors the Breda design and captures any condensate from the cold refrigerant lines attached to the expansion valve.

2.0 BACKGROUND

This overhaul utilizes EERP funding budgeted for the Rohr HVAC O/H program.

Asbestos Scope of Work Asbestos Removal / Abatement

Rohr HVAC Overhaul Project (284 Cars)

1.0 Summary

Washington Metropolitan Area Transit Authority (WMATA) has 284 Rohr cars that require removal of asbestos-containing gasket material from evaporator units at the front and rear of each car. One (1) asbestos gasket is located between evaporator coil plenum and heater plenum, one asbestos gasket (four pieces) is located on the heater access door and three insulator blocks are located in the heater plenum. Depending on notice to proceed work shall start in August ,2009 and be completed approximately 2 years later.

The schedule shall remain flexible in the event that WMATA/CMNT has to make adjustments to meet other schedule requirements. Therefore, the asbestos contractor shall be on call and be capable of responding within 24 hours after call from WMATA. Contractor shall complete work on one MP in no more than one 8-hour shift.

2.0 Scope of Work

Contractor shall provide for all necessary supervision, labor, materials, equipment and insurance for the removal and disposal of asbestos-containing gasket material from the Evaporator Units at each end of the WMATA Rohr rail cars.

All work shall be performed by a Contractor licensed in the District of Columbia to perform asbestos abatement. Contractor personnel shall be trained on proper cleanup methods, personal protection, and potential health hazards associated with asbestos. The asbestos abatement supervisor and workers shall be licensed by the District of Columbia.

All work shall comply with the following. If there are any discrepancies between this scope of work and the applicable regulations, the most stringent requirements will supersede the other.

3.0 Plan of Work

3.1 General

3.1.1 Abatement work will be completed at WMATA’s Brentwood Rail Yard, located at 601 T Street, NE in Washington, DC.

3.1.2 WMATA will provide a source of power and water for the Contractor’s use. It is the Contractor’s responsibility to route the power and water to the work area.

3.1.3 The Contractor shall provide an asbestos abatement supervisor (OSHA competent person) and asbestos abatement workers as required to complete the work in a proper and timely manner.

3.1.4 The Contractor shall provide all personal protective equipment for its staff to complete the abatement work.

3.1.5 At a minimum, half-face air-purifying respirators with HEPA filters shall be worn at all times during abatement work, including during final cleanup. Airborne fiber concentrations may not exceed 1 f/cc with this minimum respiratory protection.

3.2 Procedures

3.2.1 Contractor shall demarcate the work area (rail cars/married pair) with asbestos warning signs (in both English and Spanish) and caution barrier tape in order to restrict unauthorized access to the work area.

3.2.2 The asbestos workers shall don PPE, including at a minimum respirators and disposable suits.

3.2.10 The Contractor shall remove the three asbestos heater coil insulator blocks/ spacers. This material shall be unbolted from the evaporator unit and disposed of properly. This area shall then be wet wiped and /or HEPA vacuumed.

4.0 Air Monitoring/Analysis

The Contractor shall complete air monitoring as required by OSHA and by this scope of work. The Contractor shall retain the services of an Industrial Hygienist (IH) to collect and analyze samples. The IH shall have successfully completed a NIOSH 582 course or an AIHA-approved NIOSH 582 equivalency course.

Air samples shall be collected and analyzed by Phase Contract Microscopy (PCM), following procedures of NIOSH Method 7400. At WMATA’s option, air samples may be analyzed by Transmission Electron Microscopy (TEM). The Contractor shall submit results of all air monitoring to WMATA upon completion of analysis.

At WMATA’s option, the following samples may be collected and analyzed. At a minimum, WMATA anticipates that background, work area and clearance samples, will be collected during completion of abatement from the first four MPs.

Pre-Abatement Monitoring will determine the fiber concentrations in the work area prior to starting asbestos abatement. This monitoring shall be completed before disturbance of any ACM, including preparation of any work area.

Personal Air Monitoring will determine an individual’s exposure to airborne fibers. The sample is collected outside the respiratory in the person’s breathing zone.

Abatement Air Monitoring will determine the airborne fiber concentration at the monitoring point, inside and/or outside the work area, during abatement activities.

Clearance Air Monitoring will determine the airborne concentration of residual fibers upon conclusion of an asbestos abatement project. The concentration of airborne fibers of less than 0.01 fibers per cubic centimeter (f/cc) using PCM must be attained for successful completion of the abatement project, when final clearance air monitoring is required by WMATA.

5.0 Waste Disposal

All asbestos waste generated on this project shall be sealed into two 6-mil poly bags labeled for asbestos waste. The waste shall be transported to an EPA-approved landfill that accepts asbestos waste and a Waste Shipment Record shall be provided to WMATA upon receipt from landfill.

1.0 PURPOSE


The modification calls for certified contractor removal of accessible asbestos gaskets to eliminate potential, future issues. Asbestos will be removed at the drain pan heater box interface, the heater box lower access cover interface, and the insulator mounting block locations. Note that there are still three gaskets on the side and upper portions of the evaporator / heater box interface that will not be removed due to lack of accessibility. The existence of these gaskets will need to be conveyed to the program manager when the cars are scrapped. Evaporator coils will be cleaned while drain pans are down to allow a more thorough cleaning and improve heat transfer to the coils. The drain modification opens up the drain tubes to 1” ID and allows condensate moisture to easily drain out the bottom of the railcar without plugging up from debris. The expansion valve drain pan mirrors the Breda design and captures any condensate from the cold refrigerant lines attached to the expansion valve.

8.0 GENERAL SAFETY


9.0 TEST RESULTS

To review the procedures, refer to ETP 190389.

During installation it was found that the clearance between the bottom of the stanchion and top of the lower flange was very tight making insertion of the stanchion into the flange difficult. The lower flange diameter was opened up to 1.505” which allowed it to slide over the stanchion to ease installation. Drilling a 1.375” hole in the floorboard facilitated easier installation of the rubber tubing.

The forward bracket of the auxiliary drain pan required slight modification to make the pan level with the drip pan. Future brackets will utilize a stainless steel angle iron design.

Cleaning the coils required the use of wire brushes to thoroughly clean the unit. That procedure will be incorporated into the EMI.

The contractor doing the asbestos removal was instructed in which fasteners to remove and how to remove them. We will emphasis retaining all fasteners on future jobs.

9.1 Pass/Fail Criteria

Proper removal of the accessible asbestos.

Secure installation of the drip plates and drain pans.

Secure installation of the auxiliary drain pan.

Secure installation of the stanchions.

Proper installation of the ceiling and valance panels.

10.0 RECOMMENDATIONS AND DISPOSITION

The car was satisfactorily modified and recommended for release to revenue service.

The test period is complete. This test was to determine if the installation procedures were adequate prior to submitting the EMI. Once the EMI is approved this railcar, 1020/21 should be registered as modified per the EMI.

Recommendation(s):

a) Modify the forward retention bracket for the auxiliary drain pan.

b) Increase the diameter of the lower stanchion flange to ease installation.

c) Use wire brushes to thoroughly clean the evaporator coils.

d) Instruct the contractor to clean and retain all fasteners.

The test plan is concluded:

o Test plan was successful

o EMI 190265 will be submitted for approval

1.0 PURPOSE


The modification calls for certified contractor removal of accessible asbestos gaskets to eliminate potential, future issues. Asbestos will be removed at the drain pan heater box interface, the heater box lower access cover interface, and the insulator mounting block locations. Evaporator coils will be cleaned while drain pans are down to allow a more thorough cleaning and improve heat transfer to the coils. The drain modification opens up the drain tubes to 1” ID and allows condensate moisture to easily drain out the bottom of the railcar without plugging up from debris. The expansion valve drain pan mirrors the Breda design and captures any condensate from the cold refrigerant lines attached to the expansion valve.

At WMATA’s option, air samples may be analyzed by Transmission Electron Microscopy (TEM). The Contractor shall submit results of all air monitoring to WMATA upon completion of analysis.

At WMATA’s option, the following samples may be collected and analyzed. At a minimum, WMATA anticipates that background, work area and clearance samples, will be collected during completion of abatement from the first four MPs.

Pre-Abatement Monitoring will determine the fiber concentrations in the work area prior to starting asbestos abatement. This monitoring shall be completed before disturbance of any ACM, including preparation of any work area.

Personal Air Monitoring will determine an individual’s exposure to airborne fibers. The sample is collected outside the respiratory in the person’s breathing zone.

Abatement Air Monitoring will determine the airborne fiber concentration at the monitoring point, inside and/or outside the work area, during abatement activities.

Clearance Air Monitoring will determine the airborne concentration of residual fibers upon conclusion of an asbestos abatement project. The concentration of airborne fibers of less than 0.01 fibers per cubic centimeter (f/cc) using PCM must be attained for successful completion of the abatement project, when final clearance air monitoring is required by WMATA.

5.0 Waste Disposal

All asbestos waste generated on this project shall be sealed into two 6-mil poly bags labeled for asbestos waste. The waste shall be transported to an EPA-approved landfill that accepts asbestos waste and a Waste Shipment Record shall be provided to WMATA upon receipt from landfill.
