PAINTING OF THE RAILROAD BRIDGE

PART 1 GENERAL

1.1 SUMMARY

This section covers the requirements for the preparation and painting of the entire steel structure of the railroad Bridge, except surfaces as noted in Subpart CLEANING AND PREPARATION OF SURFACES NOT TO BE PAINTED.

Additional steel items to be painted in the machine sheave gear rooms of the bridge towers include the bridge crane and rails, and the elevated platform structural steel, rails, grating, and ships ladder.

In addition to the steel items to be prepared and painted as described above, the Contractor shall also prepare and paint the cast aluminum and bronze decorative elements at the approach span portals.

The preparation methods for all steel work include solvent cleaning ( SSPC SP 1 ) followed by commercial blast cleaning ( SSPC SP 6/NACE No.3 ).

The paint system to be applied for all steel work shall be a three coat system, plus an additional stripe coat. The first coat is a Zinc-Rich Moisture-Cure Polyurethane Primer ( SSPC Paint 40 ). The second and third top coats and the stripe coat are a Moisture-Cured Polyurethane paint ( SSPC Paint 41 ) with aluminum.

Decorative cast aluminum and bronze shall be prepared by solvent cleaning ( SSPC SP 1 ) followed by brush-off abrasive blast cleaning ( SSPC SP 16 ), power tool cleaning ( SSPC SP 3 ), or hand tool cleaning ( SSPC-SP-2), as appropriate. The paint system to be applied includes one coat of primer and three coats of metallic gold leaf paint followed by two coats of a clear acrylic paint.

The Railroad Bridge steel structure was painted with lead-containing primers as part of the original paint system and some subsequent repaintings. While the bridge structure has had the original paints and other subsequent lead-containing paint systems removed to bare steel and has been recoated with paint systems that do not contain lead, the Contractor shall assume that some areas of the steel structure still have remnants of lead-containing systems remaining. Items to be prepared and painted in the machine rooms were originally coated with lead-containing primers and paints and these coatings have never been removed. All existing lead-containing paint remains on these items. Therefore worker and environmental protection for lead, and requirements for lead waste disposal, shall be implemented in accordance with Federal, Commonwealth of Massachusetts, and local regulations, and in accordance with the requirements of this document.

SECTION 09 97 02 Page 6 required by 29 CFR 1910.146 or where the concentration of solvent vapors exceeds 10 percent of the Lower Explosive Limit (LEL). Ventilation must be in accordance with 29 CFR 1910.94 , paragraph (c)(5).

1.3.1.4 Paint Mixing

Provide local exhaust ventilation in the area where coatings are mixed.

This ventilation system must be capable of providing at least 100 linear fpm of capture velocity in the mixing zone. Avoid exposure of skin and eyes by wearing appropriate chemically resistant gloves, safety goggles, and face shields meeting the requirements of ANSI/ISEA Z87.1 . Provide a personal eyewash unit within close proximity to the mixing operation in accordance with ANSI/ISEA Z358.1 , paragraph (9). All powered mixing equipment must be either pneumatic or double insulated (intrinsically safe), in order to guard against fire or explosion. Individuals who have a history of, or develop a sensitivity to epoxy or polyurethane resin systems, must not conduct work tasks or otherwise be exposed to such chemicals.

1.3.1.5 Paint Spraying

Submit a comprehensive written Respiratory Protection Plan in accordance with 29 CFR 1910.134 , 29 CFR 1926.62 , and EM 385-1-1 , Section 5-7.b.

During all spray painting operations, spray painters must use approved SCBA or SAR (air line) respirators, unless valid air sampling has demonstrated contaminant levels to be consistently within concentrations compatible with the Assigned Protection Factor (APF) of an air-purifying respirator. Persons with facial hair that may interfere with the seal or valve function of a half or full facepiece style respirator may wear a hood or helmet respirator provided the APF is sufficient for the exposure. Air-purifying chemical cartridge/canister respirators that have a particulate prefilter and are suitable for the specific type(s) of gas/vapor and particulate contaminant(s) may be used for nonconfined space painting, mixing, and solvent cleaning. These respirators may be used provided the measured or anticipated concentration of the contaminant(s) in the breathing zone of the exposed worker does not exceed the APF for the respirator and the gas/vapor has good warning properties or the respirator assembly is equipped with a NIOSH-approved end of service life indicator for the gas(es)/vapor anticipated or encountered. Where paint contains toxic elements that may become airborne during painting in nonconfined spaces, air-purifying half- and full-facepiece respirators or powered air-purifying respirators equipped with appropriate gas vapor cartridges, in combination with a high-efficiency filter, or an appropriate canister incorporating a high-efficiency filter, must be used.

1.3.1.6 Explosion Proof Equipment

Electrical wiring, lights, and other equipment located in the paint spraying areas must be of the explosion proof type designed for operation in Class I, Division 1, Group D, hazardous locations as required by the NFPA 70 . Electrical wiring, motors, and other equipment, outside of but within 20 feet of any spraying area, must not spark and must conform to the provisions for Class I, Division 2, Group D, hazardous locations.

Electric motors used to drive exhaust fans must not be placed inside spraying areas or ducts. Fan blades and portable air ducts must be constructed of nonferrous materials. Properly maintain and ground motors and associated control equipment. Electrically bond and ground the metallic parts of all air-moving devices, spray guns, connecting tubing, and duct work.

SECTION 09 97 02 Page 7

1.3.1.7 Further Precautions

Prepare and submit an Air Monitoring Test Plan . Perform air sampling and testing as needed to assure that workers are not exposed to contaminants above the permissible exposure limit. In addition, provide the Contracting Officer with a copy of the Air Monitoring Test Report from the laboratory within five working days of the sampling date, including records of air monitoring plans and tests performed. Submit reports as soon as information is available. Also provide results from direct-reading instrumentation on the same day the samples are collected.

Prepare and submit an Airborne Sampling Plan detailing the NIOSH 2003-154 , Factory Mutual, or Underwriters Laboratories approved equipment, equipment calibration procedures, sampling methods, sampling to be performed, and analytical procedures to be used based on the type of work to be performed and anticipated toxic contaminants to be generated. Include the name of the accredited laboratory, listed by the American Industrial Hygiene Association (AIHA), that will be used to conduct the analysis of any collected air samples.

1.3.2.2 Medical Status

Prior to the start of work, and annually thereafter, submit a Report of Medical Status Records . This report will certify that Medical Status Records, in accordance with the requirements below are maintained for all required employees. The Contractor-maintained Medical Status Reports will document the medical evaluation of all employees working with or around paint systems, thinners, blast media, those required to wear respiratory protective equipment, and those who will be exposed to high noise levels for the particular type of exposure they may encounter. The Contractor-maintained Records must include the employee's name, the tests

SECTION 09 97 02 Page 8 performed and the name of the physician responsible for performing the tests, and a physician's statement that medical status would permit specific task performance. Maintain medical records as required by 29 CFR 1910.20 . The evaluation must include:

a. Audiometric testing and evaluation of employees who will work in a noise environment with a time weighted average greater than or equal to 85 dBA.

b. Vision screening of employees who will require eye protection (employees who use full-facepiece respirators cannot wear contact lenses).

c. Medical evaluation of employees who will be required to wear respiratory protection must include, but is not limited to, the following:

(1) Medical history including, but not limited to, alcohol use, with emphasis on liver, kidney, and pulmonary systems, and sensitivity to chemicals to be used on the job.

(2) General physical examination with emphasis on liver, kidney, and pulmonary system.

(3) Determination of the employee's physical and psychological ability to wear respiratory protective equipment and to perform job-related tasks.

(4) Determination of baseline values of biological indices for later comparison to changes associated with exposure to paint systems and thinners or blast media, which include: liver function tests to include SGOT, SGPT, GGPT, alkaline phosphates, bilirubin, complete urinalysis, EKG (employees over age 40), blood urea nitrogen (bun), serum creatinine, pulmonary function test, FVC, and FEV, chest x-ray (if medically indicated), blood lead and ZPP (for individuals where it is known there will be an exposure to materials containing lead), other criteria that may be deemed necessary by the Contractor's physician.

(5) For lead-based paint removal, prepare and submit a Worker Protection Plan in accordance with the requirements of 29 CFR 1926.62 , addressing all necessary aspects of worker protection. The plan must include medical screening, activities emitting lead, means to achieve compliance, alternative technologies considered, air monitoring program, implementation schedule, work practice program, administrative controls, multi-Contractor site arrangements, and jobsite inspections.

1.3.2.3 Change in Medical Status

Any employee whose medical status has changed negatively due to work related chemical and/or physical agent exposure while working with or around paint systems and thinners, blast media, or other chemicals must be evaluated by a physician, and obtain a physicians statement as described in paragraph MEDICAL STATUS prior to allowing the employee to return to those work tasks. Maintain Change in Medical Status Records detailing any negative changes in employee medical status and the results of the physicians reevaluation statement. Submit a Change in Medical Status Report detailing the negative changes in medical status and a summary of

SECTION 09 97 02 Page 9 the physician's reevaluation without including personal information of the impacted employee.

1.3.3 Environmental Protection

In addition to the requirements of Section 01 57 19 TEMPORARY ENVIRONMENTAL CONTROLS, prepare an Environmental Protection Plan incorporating the submittals for Water Quality Plan, Containment Plan, Waste Disposal Plan, Soil Quality Plan, TSP Monitoring Plan, PM-10 Monitoring Plan, and Visible Emissions Monitoring Plan. The submitted plan must also address all aspects of establishing and demarcating regulated areas, ventilation/containment system performance verification, and reporting of accidental releases. Comply with the following environmental protection criteria.

1.3.3.1 Waste Classification, Handling, and Disposal

Prepare and submit a Waste Disposal Plan in accordance with the requirements of 40 CFR 261 and 40 CFR 262 including classification and handling. The Contractor is responsible for assuring the proper disposal of all hazardous and nonhazardous waste generated during the project.

Regardless of the results of 40 CFR 261 App II, Mtd 1311, all waste generated from abrasive blasting, lead-containing paints with recyclable steel or iron abrasives must be either disposed of as a hazardous waste or be stabilized with proprietary pre-blast additives. Where stabilization is preferred, employ a proprietary blast additive, that has been blended with the blast media prior to use. Place hazardous waste in properly labeled, closed containers shielded adequately to prevent dispersion of the waste by wind or water. Any evidence of improper storage is cause for immediate shutdown of the project until corrective action is taken. Store nonhazardous waste in closed containers separate from hazardous waste storage areas. Transport all hazardous waste by a licensed transporter in accordance with 40 CFR 263 and 49 CFR 171 , Subchapter C. Transport all nonhazardous waste in accordance with local regulations regarding waste transportation. In addition to the number of copies required by 40 CFR 262.22 , supply one copy of each Waste Manifest to the Contracting Officer prior to transportation.

1.3.3.2 Containment System and Span Balancing Plan

Prepare a Containment System and Span Balancing Plan that will be used by the Contractor to provide an enclosure for cleaning and painting work while keeping the moveable span functional. Include drawings, bridge member stress calculations for all applicable load combinations. All lift span and tower span stresses are limited to the allowable stresses indicated on the original structure drawings, including the condition when train live loading is present. Contain debris generated during paint removal operations in accordance with the requirements of SSPC Guide 6 , Class 2A. The Containment Plan shall reflect that not more than three bays of the bridge (approximately 90 feet longitudinally) shall be shrouded at any one time and shrouding of the bridge towers shall occur only when the lift span is not shrouded. A minimum vertical clearance of 130 feet MLLW shall be maintained over the navigation channel.

For all abrasive blasting work on the bridge, the Contractor is responsible for designing a complete containment system including, but not limited to, a fully enclosed containment structure (containment envelope, support structure, and entryways for personnel, equipment and rail traffic); a ventilation system (forced and/or natural air input and

SECTION 09 97 02 Page 10 exhaust); dust collection equipment; and removal of debris from containment structure to a site storage facility. The plan shall include details how the containment structure, pipes, and hoses will be disconnected and secured to accommodate movement of the lift span and passage of trains. The plan shall address procedures to maintain visibility of safety lighting for both navigation and aviation interests.

The containment system shall prevent emissions of dust and debris to the ambient air, soil, and water to the maximum extent practicable; shall provide ventilation to minimize health risks and provide adequate visibility to workers; shall allow for the removal of the existing paint by the methods specified; shall be capable of withstanding wind and weather conditions that can be expected at the project site; shall be specifically designed for the physical conditions at the project site; and shall not compromise the structural integrity or exceed the capacity of the bridge members. The drawings and calculations shall be signed and sealed by a registered Professional Engineer licensed in the Commonwealth of Massachusetts.

The design, materials, configuration, mobility, size, and all other aspects of the containment system, with the criteria specified, are the responsibility of the Contractor. The Contractor shall procure the services of a structural engineer , mechanical engineer, and an industrial hygienist for designing the containment system. Since this is a moveable bridge with mechanical components that balance the span, the Government recommends that the Containment System and Span Balancing Plan be reviewed by a mechanical engineer.

The plan shall describe procedures that will be used to keep the lift span balanced with the existing main counterweights during all phases of work.

The plan shall include detailed procedures to monitor the weight of all materials placed on the bridge and counterweights. The Contractor shall reassess the Balancing Plan whenever the equipment on the bridge is changing and/or being relocated. The plan shall include a sequence that the Contractor will follow for all loads placed on the bridge and counterweighting requirements during installation of the containment system, movement of the containment system on the bridge, and removal of the system. The plan shall describe procedures that will be used to add and remove weights from the counterweights including specific lifting equipment, rigging, materials, and fastening details. The Contractor shall note that on a previous bridge painting contract, a support (similar to a cradle or basket) to hold the blocks to balance the counterweights was installed below the main counterweight location due to lack of space above the countetweight.

The plan shall address variable loading from grit accumulation within containment bays and provide a sequence to account for grit loads with counterweights.

A maximum imbalance of 8,000 pounds per tower between the lift span and the counterweights is allowable. The imbalance at the north end of lift span must be within 3,000 pounds of the imbalance at the south end of the lift span. The Contractor shall always maintain the lift span in a functional condition to move. The differential weight between the lift span and the main counterweights shall not exceed the capability of the motors to drive the span to the up position.

The Contractor shall furnish and install weights as needed to the main counterweights. USACE currently has available for use 84 concrete blocks

SECTION 09 97 02 Page 11 that weigh approximately 120 pounds each and 40 concrete blocks that weigh approximately 60 pounds each. The larger block dimensions are approximately 11.5" X 11.5" X 12". The smaller block dimensions are approximately 11.5" X 11.5" X 6". The Contractor shall confirm the weights of all blocks used for counter-balancing the lift span.

1.3.3.3 Visible Emissions Monitoring

Prepare a Visible Emissions Monitoring Plan including the provisions for halting work and correcting the containment in the event unacceptable emissions are observed. General statements must not be used; specific methods, procedures, and details are required. Measure the time of emissions in accordance with 40 CFR 60 , App A, Mtd 22. Monitor visible emissions for not less than 15 minutes of every hour. Calculate visible emissions for each hour by extrapolation. Visible emissions must not extend greater than 150 feet in any direction horizontal from the containment. Visible emissions must not be observed in the area of any sensitive receptor. If such emissions occur shut down the job immediately and take corrective action. Notify the foreman whenever visible emissions exceed 40 seconds in a 1 hour period. Whenever visible emissions exceed 75 seconds in a 2 hour period notify the foreman, shut down the job, and take corrective action. If the total observed visible emissions from the containment exceeds 1 percent of the work day, shut down the job and take corrective action to prevent such an occurrence. Document each time that the work is halted due to a violation of the visible emissions criteria.

Documentation must include the cause for shutdown and the corrective action taken to resolve the problem.

1.3.3.4 TSP Monitoring

Prepare a TSP Monitoring Plan for monitoring emissions of Total Suspended Particulates (TSP) in compliance with the requirements of EPA regulation 40 CFR 50.12 and this paragraph. The plan must include provisions for halting work and correcting the containment in the event unacceptable emissions occur. Position the air monitoring equipment in accordance with 40 CFR 58 , App E, Subpart (8). A minimum of two TSP monitors must be used at the project site, one downwind from the project and one in the area of greatest public access (e.g. playground, school yard, or homeowner's yard). When the project is in an area where there are critical receptors nearby, TSP-lead monitoring must be conducted throughout the entire period that abrasive blasting and cleanup operations are performed. Otherwise, perform monitoring 4 of the first 8 days and on a regular basis thereafter for a sum total of 25 percent of the time surface preparation and debris cleanup are performed. If air quality regulatory limits are not met, require air monitoring to be repeated immediately after corrective actions have been taken. Also conduct preproject TSP monitoring. Conduct the preproject TSP monitoring a minimum of 2 weeks prior to the beginning of the project and continue the monitoring for a minimum of 3 days to establish background levels. Submit a TSP Test Report to the Contracting Officer within 48 hours including:

a. Name and location of jobsite.

b. Date of monitoring.

c. Time of monitoring (i.e., time monitoring begins and ends each day).

d. Identification and serial number of monitoring units.

SECTION 09 97 02 Page 12

e. Drawing showing specific location of monitoring units.

f. Drawing showing specific location of paint removal operation and the method of removal or work activity being performed.

g. Wind direction and velocity.

h. A flow chart verifying the rate of air flow across the filter throughout the sampling period.

i. Name and address of laboratory.

j. Laboratory test procedure.

k. Laboratory test results.

l. Signatures of field and laboratory technicians conducting the work.

1.3.3.5 Water Quality

Prepare a Water Quality Plan for all job sites where lead-containing or other hazardous paint will be removed, including provisions for halting work if spills or emissions are observed entering into bodies of water or found in areas where storm water runoff could carry the debris into bodies of water or storm sewers. The plan must also address cleanup and reporting procedures. Conduct operations in such a manner that lead-containing and other hazardous paint debris do not contaminate the water and so that NPDES permits in accordance with EPA regulation 40 CFR 122 are not required for the project. Any release of lead paint debris into the waterways having a reportable quantity of hazardous substance pursuant to Section 311 of the Clean Water Act, must be reported to the EPA in accordance with 40 CFR 117 and 40 CFR 355 . The plan must require the thorough documentation of any release or spill that carries into waterways or storm sewers. Include the time and location of the release, amount of material released, actions taken to clean up the debris, amount of debris recovered, and corrective action taken to avoid a reoccurrence. Also report releases to the Coast Guard and other state and local authorities as appropriate. If the release is equivalent to 10 pounds or more of lead-containing material in a 24-hour period, it is considered to be a reportable quantity under CERCLA. Comply with

40 CFR 302 .

1.3.3.6 Soil Quality

Prepare a Soil Quality Plan for all job sites where lead-containing or other hazardous paint will be removed. The plan must include provisions for halting the work should soil contamination occur, correcting the deficiencies responsible for the contamination, and provide procedures for removing and replacing contaminated soil. Establish and implement practices and procedures for preventing contamination of the soil from the removal of lead-containing or other hazardous paints. Unless otherwise directed by the Contracting Officer, soil is considered to have been contaminated by the Contractor's operation if an increase in the total lead content of 100 PPM or greater over background levels occurs. For purposes of computing the increase compute the mean background levels and the mean post-removal levels. The 100 PPM criteria is met if the difference between the means is less than 100 PPM plus the 95 percent confidence limit. Conduct soil sampling and testing prior to the beginning of the project and after the project is completed. Interim

SECTION 09 97 02 Page 13 testing may also be performed in the event the Contractor or Contracting Officer wants to confirm that the containment system and work practices continue to provide satisfactory protection of the soil. Unless otherwise directed by the Contracting Officer, the following minimum test locations must be selected for soil analysis. Select two locations beneath or immediately adjacent to the structure being prepared. Take additional samples within 100 feet in each direction of the project (i.e., N, S, E, W) in which soil is present. The number of soil sample locations must be sufficient to adequately characterize the soil contaminant levels within and around the project area. Collect five composite samples at each location. Each of the five samples must be comprised of five individual plugs of soil combined in a single bag. Use the following procedure to collect the composite samples:

a. Place a 1-square foot template at each location.

b. Remove a sample of soil 3/4 inch in diameter and 1/2 inch in depth at the center of the template and at each of the four corners. Place the five soil plugs into a single bag. This represents one of the three samples to be removed at a given location.

c. Move the template 1 inch in any direction and repeat the process to collect the second sample. Place all plugs in a separate bag. Move the template 1 inch farther to collect the third sample.

d. Identify each sample bag with the date, specific location of the sample, name and signature of the sampling technician, and complete chain of custody records.

e. It is critical that the specific location of each sample be thoroughly measured and documented as the final project testing (and any interim testing) must be sampled in the precise locations.

Analyze three samples collected at each location. One of the remaining two samples is to be maintained by the Contractor for the duration of the project and the other by the Contracting Officer in the event reanalysis is required. Analyze lead-containing samples in accordance with EPA testing guidance as published in 40 CFR 261 , App III, by a laboratory listed by the American Industrial Hygiene Association (AIHA) as being proficient in conducting the test. Note that if it is determined that contamination of the soil has occurred as a result of the paint removal operations, TCLP testing must be employed to determine if the soil must be handled and disposed of as a hazardous waste. The initial sampling of the soil for total lead content does not establish whether the soil will be considered hazardous by TCLP testing. As a result, at the Contractor's option, additional prework soil samples may be removed (minimum of 105 grams is required for a single test at each site) to conduct TCLP testing to establish whether the soil would be classified as hazardous prior to project startup. In the event that there is a release of lead paint debris onto the soil and if the release is 10 pounds or more of lead-containing material in a 24-hour period, it is considered to be a reportable quantity under CERCLA. Comply with 40 CFR 302 . Thoroughly document the occurrence of any spills of lead debris into the soil. The documentation must include the time and location of the release, amount of material released, actions taken to clean up the debris, amount of debris reclaimed, and corrective action taken to avoid a reoccurrence. Provide the documentation to the Contracting Officer including the Soil Quality Test Report with results of the prework and post work soil quality tests.
