I <br /> 1 1) Containment basin shall be constructed of durable plastic sheeting with continuous <br /> sidewalls supported by hay bales, ecology blocks, other non-contaminated materials, or <br /> support structure to contain all sediment and creosote. Containment basin shall be lined with <br /> oil absorbent boom. <br /> 2) Work surface shall be cleaned by disposing of sediment or other residues along with cut <br /> off piling as described in BMP #4.B. <br /> 3) Containment basin shall be removed and disposed in accordance with BMP #4.B or in <br /> another manner complying with applicable federal and state regulations. <br /> 4) Upon removal from substrate the pile shall be moved expeditiously from the water into <br /> the containment basin. The pile shall not be shaken, hosed-off, left hanging to drip or any <br /> other action intended to clean or remove adhering material from the pile. <br /> BMP 3. DEBRIS CAPTURE IN WATER <br /> A. A floating surface boom shall be installed to capture floating surface debris. The floating <br /> boom shall be equipped with absorbent pads to contain any oil sheens. Debris will be <br /> collected and disposed of along with cut off piling as described in BMP #4. <br /> B. The boom shall be located at a sufficient distance from all sides of the structure or piles that <br /> are being removed to ensure that contaminated materials are captured. The boom shall stay <br /> in its original location until any sheen present from removed pilings has been absorbed by <br /> the boom. BMP #3B may be used to keep the boom in its original location. <br /> C. Debris contained within boom shall be removed at the end of each work day or immediately <br /> if waters are rough and there is a chance that debris may escape the boom. <br /> D. To the extent possible all sawdust shall be prevented from contacting the waters of the state. <br /> For example, sawdust on top of decking should be removed immediately after sawing <br /> operations. <br /> E. Any sawdust that enters the water shall be collected immediately and placed in the <br /> containment basin. <br /> F. Piles removed from the water shall be transferred to the containment basin without leaving <br /> the boomed area to prevent creosote from dripping outside of the boom. <br /> 1 <br /> I <br /> 3 Updated 3/19/2013 <br /> i <br />
