M/V Columbia Vessel Specific Sampling Plan (VSSP) ADEC approved as written on /2015

Transcription

1 Vessel Specific Sampling Plan M/V Columbia The sampler will use the VSSP as a guide to identify the specific onboard location(s) and sources to be sampled. To satisfy the VSSP requirement, you may fill in the blanks in this form starting on page 2 or you may submit an existing up to date VSSP if it contains the components listed in 18 AAC (b). Please note that ADEC will not approve sampling locations that are more than 50 feet from the overboard discharge port. Samples taken in 2003 indicated that samples taken directly after the ultraviolet disinfection unit were not of the same quality as samples taken at the overboard discharge pipe. The wastewater samples that are taken to satisfy the state requirements must reflect the quality of the effluent that is being discharged into Alaska waters during standard operating procedures. In port discharging vessels that have obtained continuous discharge certification from the U.S. Coast Guard but choose not to discharge in port as part of their standard operating procedures, may sample while the vessel is underway. Cruise ships operating under a DEC discharge permit must obtain the required number and types of samples as listed in the permit. Cruise ships sampling for USCG continuous compliance must follow the USCG requirements for sampling. If you have questions concerning the components of the VSSP, please contact Albert Faure (907) or by albert.faure@alaska.gov. ADEC approved as written on /2015 The plan is missing or insufficient in the following areas: List of VSSP Updates: Page 1 of 9

The aft collection tank V-3 tank holds 15,028 gallons. The wastewater collected in the aft tank is pumped to the forward collection tank (V-1 tank 12,567 gallons). Float switches automatically start the transfer pump at 50% and shuts the pump off at 20% tank level. All wastewater enters the forward collection tank (V-1) from gravity drains and transfer from the aft collection tank. All four treatment units operate in parallel. Operation sequencing of these treatment units is done automatically in pairs. Two Omnipure 15MX lead units start when forward holding tank reaches 40% capacity and shut off at 20% capacity. Two additional units start at 60% capacity and shut off at 30% capacity. When activated by V-1 tank level switches, the macerator pump for each treatment unit takes the contents of V-1 tank, mixes it with incoming seawater, then sends it through the book cells to the V-2 (3,927 gallons) effluent tank. The wastewater is chlorinated as it passes through the book cells. This book cell is a hypochlorite generating system which reacts with the salt in the sea water. The plates also cause rapid chemical oxidation of organic constituents of wastewater. The V-2 process tank is a 3,927 gallon tank. This tank is an independent tank located in the MSD room that shares one side with the V-1 tank. The processed wastewater from the treatment units enters the tank in downcomers to the bottom of the tank. The overflow discharge is near the top (80% 90%) of the tank capacity. This flow pattern is designed to allow the processed (chlorinated) waste water to reside inside this V2 process tank for at least a one-half hour period. This time period is used for the chlorine to react completely with the waste water prior to discharge overboard. The (V-2) effluent tank is discharged overboard through the use of 4 each ECO Model C-10A-OS- VD pumps rated at 10.4 gals/min. These pumps stop and start as each of the processing units start and stop. These 4 pumps are part of the 4 Omnipure 15MX units. When all four MSD units are running, then the V2 tank discharge rate is 4 x gal/min= gallons/min (maximum discharge rate). The minimum discharge rate is with one MSD running and one ECO pump running; 1*10.42 gal/min= 10.42gal/min (minimum discharge rate). Page 3 of 9

4 A liquid chlorine chemical feed dosing system complete with chlorine tank and a dosing pump is part of the treatment system. This chlorine injection system is used as a backup treatment system if there is insufficient salinity in the seawater. In areas of low salinity, the MSD units will alarm on high voltage. The operator will then put the MSD unit in the override mode and turn on the chlorine injection pump. The flow rate of the chlorine injection is adjusted so that the overboard effluent has free chlorine reading about 1 2 ppm. Each Omnipure unit includes the following alarms any of which will set off a summary malfunction alarm in the engine control room: High level alarm High temperature alarm High pressure alarm System alarm (summary) Over voltage alarm Discharges All discharges occur automatically based on levels of the V-1 tank as described above. Operation in port is currently the same operation as at sea. Procedures for minimizing discharge in port are being developed see BMP plan. The crew keeps a log of estimated discharges based on the number of persons onboard and the estimate of 22 gals gray water and 8 gals black water generated per person per day. Crew will conduct a daily test of the waste water effluent for total chlorine and record the readings in the Chief Engineers Weekly Report. This total chlorine test is the manufacturers recommended on board method for determining the quality of the treatment being accomplished. Wastewater Samples To Be Analyzed For Conventional Pollutants At Least Twice Per Season Sampling will take place in the port of Juneau shortly after arrival during the day. ( so that Samples can be delivered to the testing laboratory and kept refrigerated) The newly installed sample connection is located in the combined discharge piping from all four overboard discharge pumps. This representative sample is the combined black and gray waste water going overboard after processing has been completed. Sampling valve will be labeled DEC sampling. DEC sampling valve is located in the MSD room starboard side 2 feet forward of the bulkhead on frame 73 about 7 feet above the floorplates in a 6 horizontal piping run. Sample is to be taken minutes after an overboard pump cycles on. The sample location is less than 50 feet from the overboard discharge. The estimated distance is 30 feet. Page 4 of 9

5 Wastewater Samples To Be Analyzed For Priority Pollutants Once Per Season Sampling will take place in the port of Juneau shortly after arrival during the day. ( so that Samples can be delivered to the testing laboratory and kept refrigerated) The newly installed sample connection is located in the combined discharge piping from all four overboard discharge pumps. This representative sample is the combined black and gray waste water going overboard after processing has been completed. Sampling valve will be labeled DEC sampling. Sampling valve will be labeled DEC sampling. DEC sampling valve is located in the MSD room starboard side 2 feet forward of the bulkhead on frame 73 about 7 feet above the floorplates in a 6 horizontal piping run. Sample is to be taken minutes after an overboard pump cycles on. The sample location is less than 50 feet from the overboard discharge. The estimated distance is 30 feet. Description of the standards the owner or operator will use to determine a deviation from the plan. Ships crew will conduct daily onboard total chlorine testing from the DEC sampling test connection. They are using a Hach Company color comparator type test. (Kit # ) that reads from 0 to 3.5ppm. If the reading exceeds the 3.5ppm, the operator would dilute the effluent sample with 50% distilled water and retest. (test results are then doubled to a range of 0 7ppm) Readings are expected to vary from 0 to 5 parts per million depending on the loading of the system. The optimum reading is above zero but below.5 ppm as the lower chlorine levels are less harmful to sea life. An occasional zero is acceptable. A constant zero reading indicates a problem, which is to be repaired immediately. AMHS is requiring that if zero reading is found - that a 2 nd reading must be taken within 24 hours. If there is a second zero reading, this requires shipboard investigation and repairs to commence. If there are 3 days with zero readings the assigned port engineer and the port captain must be notified by providing information on what steps are being taken to resolve the situation and perhaps a request for outside assistance if necessary. A follow up is required to both the port captain and the assigned port engineer when the problem is solved. If the effluent chlorine reading exceeds 5 ppm (mg/liter) the ship is instructed to take corrective action. This corrective action could be any of the below actions: Reduce the flow rate of the chemical feed pump (if it is use) Discontinue any double processing of waste water. (Some operators feel it is helpful to pump the V-2 processing tank back to the V-1 fwd. collection tank to help reduce the cellulose mat buildup in the V-2 tank. Discontinue use of Chlorine Bleach by staff cleaning rooms. Contact manufacturer for trouble shooting advice. Page 5 of 9
