Dry Cargo Residue (DCR) April 2016 1 4/19/2013
Dry Cargo Residue (DCR) Rule The Coast Guard has finalizing it s Dry Cargo Residue rule March 3 rd 2014 regulating the operations of U.S. and foreign vessels carrying bulk dry cargo such as limestone, iron ore, and coal on the U.S. waters if the great lakes, and the operation of U.S. Bulk Cargo Vessels anywhere on the Great Lakes. The Coast Guard has published new requirements for the discharge of bulk dry cargo residue(dcr) on the U.S. waters of the Great Lakes. The rule will continue to allow non-hazardous and non-toxic discharges of bulk DCR in limited areas of the Great Lakes. Discharge of limestone and clean stone DCR no longer permitted within three miles of shore. One exception is western basin of Lake Erie. Discharge allowed within the dredged navigation channel between Toledo Harbor Light and Detroit River Light. Vessel owners and operators will need to minimize DCR discharges using methods they will be required to document in DCR management plans. The final rule promotes the Coast Guard s maritime safety and stewardship missions 2 4/19/2013
Lake Carrier Association Final Rule Does Not Preempt State Laws Neither the Interim Rule nor this Final Rule expressly preempts State laws relating to DCR discharges. Carriers must comply not only with USCG DCR regulations, but with all applicable Federal and State laws regulating DCR discharges. The CG will work with States and carriers to make sure carriers are informed of any State laws that could impose more restrictions on DCR than are imposed by this Final Rule. Possible Clean Water Act Issue with Sumping; The CG acknowledges that sumping is necessary to preserve the vessel s stability and safety in transit, so the Final Rule does not preclude that pumping. However, one commenter urged the Coast Guard to determine if the Clean Water Act applies to sump pump discharge of DCR-laden effluent. The Coast Guard takes no position on that question, as it is outside the scope of this Final Rule. 3 4/19/2013
Dry Cargo Residue (DCR) Rule Provision Description Interim Rule (IR) IR Provision Synopsis Final Rule Provision Final Rule Provision Synopsis Change from IR to Final Rule Reporting /Certification 33 CFR 151.66 (c) (1) (iv) The data collected are used to determine vessel practices in handling DCR, and the amount of DCR being managed N/A Vessels will continue to certify and submit reports on a quarterly basis for 13 months after the publication of the final rule. Limestone and Clean Stone 33 CFR 151.66 (b) Limestone and clean stone are exempt from the 3 mile near shore sweeping boundary. Under the IR these commodities can be discharged anywhere along the shoreline. 33 CFR 151.66 (b) (2) Limestone and clean stone DCR discharges,under the final rule would not be allowed within 3 miles of shore There would be a no-cost change; our research indicates that vessels already avoid DCR discharges within the 3 miles of shore because of nearshore operational hazards Voluntary Minimization 33 CFR 151.66 (b) Vessels are encouraged to minimize the amount of DCR going into the water and control measure to reduce the amount falling from decks and tunnels N/A The portion of 33 CFR 151.66 (b) in the IR dealing with voluntary minimization would be removed in the final rule 4 4/19/2013 The portion of 33 CFR 151.66 (b) in the IR dealing with voluntary minimization would be removed in the final rule
Calcite Plant South Dock Vessel Discharge Systems Outlines the current system for accepting vessel discharge, as well as the plan and design parameters for the construction of a permanent vessel water discharge pipe system on the south dock: Current Temporary System. 250 of 1½ rubber hose on dock. Additional 50 shots of hose available if needed. (550 total length of hose) 1½ aluminum camlock fittings on both ends of hose. o Type E camlock (male) on one end to connect dock hose to vessel hose. o Type C camlock (female) on other end to connect dock hose to standpipe that runs into dock sump and tailings water system at L-9 conveyor. Vessels run 1½ hose fitted with a female camlock out their gangway and onto the dock to connect to dock hose. (Hose could be run off deck of vessel if such a set-up was easier for vessel.) Hose can be moved up and down dock as needed to adjust for vessel shifting. 5 4/19/2013
Calcite Plant South Dock Vessel Discharge Systems Potential Permanent 365 Pipe Header System to Run Parallel to the South Dock. 4 Pipe Gravity fed, routed to L-9 conveyor sump, where the pipe system will tie in to the tailings water system. 3% slope to prevent settlement inside pipe. Tap-in points (T-joints) located every 40 of pipe. 1½ male camlock fittings at every T-joint tap-in point. Tap-in points to accept 1½ hose from vessel fitted with the 1½ female camlock. Pipe system to be mounted to pre-existing concrete barriers located along south dock. Pipe will rise to a max height of 9 from the ground at the westernmost tie-in point. o o Stairs and platform to be built to access tap-in point. Similar set-up for all tap-in points which are too high to access from the ground. 6 4/19/2013
