714 - PAINTING STRUCTURAL STEEL
700-71 (6) Submit all documentation relative to air and water sample collection and analyses to the ESS within 30
days of completion of the paint removal process. If documentation is not submitted, the Engineer may stop work on the project until such documentation has be en received by the Engineer and ESS.
c.Notifications and Record Keeping. The ESS will submit a SRFS report to the Bureau of Waste Management (BWM), KDHE, Forbes Field, Topeka, Kansas 66620-0001 a maximum of 60 days before beginning work on the bridges. At the same time, a copy will also be provided to the Bridge Management Section and the appropriate KDOT Distri ct Office. The District Office will provide a copy of the Site Review and Field Survey report to the Contractor. At the conclusion of the blasting operations, the ESS will submit a report to the BWM, which includes the results of all air, soil, and surface water samples obtained duri ng the project. A copy of this report will also be provided to the appropriate District Office. The Contractor may receive a copy of this report upon request to the Engineer or ESS.
d.Lead Base Paint Removal. The Contractor engaged in lead base paint removal operations must carry a pollution liability (access liabilit y) policy with a minimum coverage of $1,0 00,000. Maintain this policy in force until the Secretary releases the Contractor from all obliga tions under the contract. The insurance contract must cover claims for such length of time as said claims are permitted by law. Provide a copy of this insurance certificate to the Engineer prior to beginning lead base paint removal operations. Use best industry practices to prot ect the environment, persons and ad jacent property from contamination due to blasting of the existing structure. When "Power Wash" is shown as a bid item, clean the existing steel before initiating the blasting operations. Use a power washer with pr essure in the range of 700 to 1000 pounds per square inch to clean the structure, at a maximum rate of 4 gallons per minute, using potable water. Comply with all applicable regulations contained in K.A.R. 28-16-28 (b) through (f) for protection of water quality, K.A.R. 28-29-1 through
28-29 27 for disposal of solid waste and K.A.R. 28-31-1 through 28-31-14 for disposal of hazardous waste. In
addition, comply with all applicable Occupational Safety and Health Administration standards including those found in 29 CFR 1910.1025 covering the occupationa l exposure to lead and 29 CFR 1926.62 outlining the requirements for the removal of lead-based paint from bridge repair and rehabilitation activities. Contain paint chips, corrosion residues and spent abra sives, referred to as waste materials, resulting from blasting and other cleaning operations. The containment requirements are covered in subsection 714.4e . Use special containment methods or removal procedures over power lines, communication lines, railways or roadways not closed to traffic. Obtain the permits and permission from the line owner on the containment methods and removal procedures. The proposed containment method or removal procedures must be sealed by a licensed Professional Engineer, and submitted to the Engineer before commencing paint removal operations. Clearing of the work area for containment purposes is the responsibility of the Contractor. Clearing may not extend beyond right-of-way. Burning on the right-of-way is prohibited. The area to be cleared and the clearing method must be approved by the Engineer before starting the clear ing operation. Provide locations, approved by the Engineer, and dispose of all the debris at said locations.
e.Removal and Containment Requirements.
1.Class A Bridges. On all Class A bridges, provide a KDHE certified Lead Abatement Supervisor for oversight of all paint removal, storage and disposal operation. These operations shall adhere to work practices established in K.A.R. 28-72-18(g) and K.A.R. 28-72-18d(a). The Lead Abatement Supervisor must have available at the job-site a telephone number for the nearest Local Emergency Planning Commission (LEPC), or if none can be found within a 50 mile radius, the nearest Haz-Mat Response Contractor. Dry abrasive blasting or any other approved method which meets the paint specification may be used to remove the lead paint from the bridge. Use the containment methods shown below to maximize pollution control.
a.Power Tools: Use containment unless the power tools are vacuum equipped and all parts of the vacuum equipment are in a condition that prevents emissions of wast e material. This determination will be made by the Engineer. (b) Dry Abrasive Blasting: Use 100% air impenetrable walls with rigid or flexible framing, fully sealed joints, airlock or resealable entryways, and negative air achieved by forced or natural air flow (verified by instrument or visual monitoring) and exhaust air filtration (See SSPC – Guide 6, Paragraph 4.2.2.1). Design the containment to withst and the effects of negative air pressure equal to the combined volume of all blast nozzles inside the enclosure plus 4 air changes of the enclosure per hour. The 714 - PAINTING STRUCTURAL STEEL
700-72 method of attaching and the effect s of dead load caused by the inst allation of the enclosure to the
bridge shall be sealed by a licensed Professional Engineer. Provide a copy of such plans to the Engineer for approval before commencing paint removal operations. Recyclable or non-recyclable abrasive may be us ed. Use recyclable abrasives with a classifier system rated to remove a minimum of 98% of the non-abrasive material, and free of oil substances. Do not allow the waste material to contact th e ground or water surface. Plywood or other impermeable material may be used, subject to approval by the Engin eer. When the roadway beneath the structure is closed, th e hard surfaces such as asphalt and concrete roadway, sidewalks and sloped paving may be left uncovered if they have an unbroken surface, and can be cleaned by sweeping or vacuuming as described in subsection 714.4f.(1) . If the roadway surface is used for waste material collection, cover the storm drains.
c.Visible emissions are permitted at given frequencies or durations provided they do not extend beyond KDOT right-of-way. Permissible visible emissions for Class A bridges are defined as random emissions of a cumulative duration of a maximum of 1% of the work day, equivalent to 5 minutes in an 8 hour period (See SSPC-Guide 6, Pa ragraph 5.5.1.1). The Engineer will determine if visible emissions limitations ar e being exceeded. Temporary susp ension of work on the project may be ordered by the Engineer if visible em issions exceed limitations. The ordering of a temporary suspension for exceeding emissions limitations will not alter or waive the charging of working days for the project.
2.Class B Bridges. Dry abrasive blasting or any other approved method which meets the paint specification may be used to remove the lead paint from the bridge. Use the containment methods shown below to maximize pollution control.
a.Power Tools: The Contractor is subject to th e limitations for Class A Bridges as described in subsection 714.4e.(1)(a) .
b.Dry Abrasive Blasting: Use 100% impermeable tarpaulins or heavy plastic (6 mil minimum thickness) to prevent disposition of waste material on the soil or water surf ace. Plywood or other impermeable material may be used subject to approval by the Engineer. Overlap the ground cover a minimum of 1 ½ feet and weight them as needed to prevent separation. Cover all bare soil and vegetated areas inside the curtains required by items below, and extend a minimum of 20 feet beyond in all directions except at abutments. When the roadway beneath the structure is closed, the hard surfaces such as asphalt and concrete roadway, sidewalks and sloped paving may be left uncovered if they have an unbroken surface, and can be cleaned by sweeping or vacuuming as described in subsection 714.4f.(1) . If the roadway surface is used for waste material collection, cover the storm drains. Curtains: Use curtains in the form of rigid or flexible walls, rated by the manufacturer at a minimum of 85% impermeable to contain lead paint particles and dust generated from the blasting operation. Use curtains with adequate strength to withstand wind velocity. Plywood or other impermeable material may be used, subject to approval by the Engineer. Attach and overlap the edges of the walls a minimum of 3 feet, unless the edges ar e completely joined. Girders and Deck Trusses: Rigid or flexible walls may be suspended from the bridge deck to the ground so that the work area is contained on all 4 sides. Attach and overlap the edges of the walls a minimum of 3 feet, unless the edges are completely joined. Extend the wall up between the girders to seal this space. Extend th e walls to the ground, an d anchor or weight at the bottom. An exhaust fan with an adequate filter system may be required to protect the personnel within the confinement. Thru and Overhead Trusses: If the roadway is open to traffic, suspend rigid or flexible 85% impermeable walls both inside and outside of the truss from a height greater than the point to be removed, with the inside edge resting on the deck and secured by weights, and the bottom outside edges fastened within the lower walls attached to the bridge deck in the manner required for girders. If the roadway is closed to traffic, susp end rigid or flexible 85% impermeable walls outside from a height greater than the point of paint removal with the lower edges fastened within the lower walls attached to the bridge deck in a manner required for girders; or suspend a rigid barrier outside the truss with the bottom edge resting on or directly above the roadway and inclined at an angle of 45° with the truss to deposit waste material on the closed roadway. 714 - PAINTING STRUCTURAL STEEL
700-73 The height must be at a minimum, equal to the height of the truss, and with the space
between the end of the barrier and truss closed with impermeable material. Suspend rigid or flexible walls across the bridge deck between th e opposite trussed at both ends of the area to be blasted. On truss bridges provide a document sealed by a licensed Professional Engineer noting the amount of work area allowed for containment. Over a Body of Water: If a project site is located within 0.5 mile upstream of any public water supply intake, the ESS will notify the app licable public entity of project activity within 30 days of commencing paint removal operations. Rigid or flexible 100% impermeable material may be suspended horizontally beneath the bridge deck to contain the waste material; or suspend scaffolding that supports a platform beneath the bridge deck lined with impermeable material to contain the waste material; or for bridge decks within 50 feet of the water surf ace, anchor a barge beneath the bridge and use impermeable material to direct waste material to the barge; or for bridge decks that are within 50 feet of a frozen water surface, collect and remove waste material from the ice surface with ground cover as required in subsection 714.4e.(2)(b) . Extend the distance of ground cover in a downwind direction to a distan ce greater than the highest point of the paint removal. Extend the material used to contain the girders and trusses from outside the paint surfaces to inside of the containment walls, the platform, inside the barge or inside the containers on the barge. Over a narrow body of water, the following methods may be used as an alternate to the methods shown above. Cover a platform abov e the water surface with 100% impermeable material that overlaps the ground covers; or suspend an impermeable material across the underside of the bridge deck at a point more than halfway across the water body to direct paint particles to the farther bank. Anchor the containment at the bank so that it overlaps the ground covers, and seal the space above the cont ainment in between the beams. Repeat the procedure in the opposite direction. The rigid or flexible walls used to contain the material from the girders or the trusses shall extend from outside the painted su rfaces to the platform or inside the horizontal containment material. In addition, employ floating booms down gradient of the structure if any waste material is detected floating on the water surface. Use a skimmer or wet vacuum to capture any waste material or paint chips.
3.Wind Speed Limitations: Do not conduct paint removal operations whenever wind speed or other weather conditions render the containmen t ineffective or unsafe. If excessive visible emissions of particulate matter occur in the air or in visible deposits on the ground or water surface due to adverse weather conditions, either halt operations until the weather and/or wind speed is at a work able level, or increase design controls to adequately accommodate weather related conditions. The Engi neer shall make this determination.
4.Alternative Method of Removal: Alternate methods of removal may be proposed. Submit the alternate proposal to the State Bridge Engineer a minimum of 30 days in advance of use. Include site-specific design and engineering controls appropriate for the proposed alternat ive method. The alternate method must be approved by KDHE and KDOT before initiation.
f.Waste Material Cleanup , Storage and Treatment.
1.Cleanup of Waste Material: Clean up all visible de posits of waste materials at the end of each work day and store them in secured containers above normal high water elevation, within KDOT right-of-way as describe in further detail in item subsection 714.4f.(3) . Recover this material by manual m eans or by vacuum with filtration. Do not use an air pressure or a water stream which redistributes, but does not remove the waste material. Collect material from the roadway and from floating booms as ne eded, and at a minimum at the end of each day.
2.Storage of Waste Material: Consider generated waste material to be a hazardous waste until representative analytical results have been received by the ESS and the Engin eer, indicating that the waste is non- hazardous, pursuant to 40 CFR 261 and the KDHE.
a.While classified as a hazardous waste, store the waste material accordin g to the requirements of K.A.R. 28-31(g) or (h). In addition to K.A.R. 28-31(g) or (h), in the plan for storage of waste material, include the following: Store the waste material in secured drums, bulk hoppers, bins or rolloffs. Clearly mark the containers with the words “Hazardous Waste”, the KDOT project number and the date upon which the period of accumula tion began for each container; 714 - PAINTING STRUCTURAL STEEL
700-74 Store the waste containers on an impermeable surface that accommodates sweeping or
vacuuming; Do not accumulate h azardous waste for more than 90 days. If an extension of time is needed, seek approval from the ESS; and The Engineer is designated the “Emergency Response Coordinator” and is responsible for coordinating all emergency response meas ures outlined in K.A.R. 28-31-40(h).
b.In order to classify generate d waste as non-hazardous for on s ite storage, obtain a minimum of 2 composite samples at the direction of and in the presence of the Engineer. The sample must be representative of the total volume of waste generated through that point in time, as determined by the Engineer. Submit the samples to a KDHE cer tified laboratory and test for lead according to the TCLP Method SW 1311/7420, pursuant to 40 CFR 261, Appendix II. Maintain proper Chain of Custody forms at all times. The Contractor shall bear the costs of all sampling and analyses. If the sample analyses indicate the waste to be non-hazardous, less than 5 mg/L, the analytical results serve as representative documentation for the remainder of the waste generated on that project site, provided changes are not made to the method of paint removal, the type of blast media or any other portion of the paint removal operation that would render the samples non- representative of the total volume of waste. These criteria will be evaluated at the discretion of the Engineer; KDOT reserves the right to conduct random sampling at any time to assure that paint removal operations have not been altered in such a way as to compromise the representative nature of the original samples. KDOT w ill bear the cost of any random sampling ordered unless said sample analyses determines the waste to be hazardous, whereupon the Contractor will be responsible for the cost of samp le analyses. If the waste is found to be hazardous through random sampling, the entire volume of waste generated shall be considered hazardous; Store non-hazardous waste material in secu red containers and place on an impermeable surface which accommodates sweeping or vacuuming; and Mark each storage container with the KDOT project number and date upon which the period of accumulation began.
3.Sampling and Analysis of Waste Material. Collect representative composite samples of the wa ste material at the di rection of and in the presence of the Engineer. Sampling and testing procedures and contaminant limits are described in subsection 714.4f.(2)(b) ; A minimum of 2 samples are required and may be the same 2 samples described as initial waste characterization in subsection 714.4f.(2)(b) . Additional samples shall be required in order to total a minimum of 2 samples per ton of waste generated. The Contractor shall bear the cost of all sampling and analyses; All samples collected must fall below the 5 mg/L TCLP regulatory requirement in order to dispose of any of the waste as non-h azardous, pursuant to K.A.R. 28-29-109.
4.Disposal of Waste Material.
a.If all samples indicate a lead content below 5 mg/L, dispose of the entire volume of waste generated as follows: Provide documentation confirming the disposal of said waste at a KDHE permitted landfill to the Engineer within 15 business days of the disposal. If documentation is not submitted, the Engineer may stop work on th e project until such documenta tion has been received by the Engineer and ESS; or Recycle according to subsection 714.4f.(4)(b) ; DO NOT DISPOSE OF THIS MATERIAL AS A HAZARDOUS WASTE.
b.If any sample indicates a lead content at or above 5 mg/L, recycle the entire volume of waste generated as follows. Recycle waste material through an EPA approved lead recycling facility, pursuant to 40 CFR 261.1. For the purposes of transport, the waste may be designated as “recyclable”;
