The specificprocedures to be followed at any launch facility must be approved by theapplicable regulatory agencies and the Lake Tahoe AIS Program. Currently,the AIS program of roadside washing stations takes precedence. Theintroduction of AIS at Lake Tahoe is a serious threat; hence, all boats planningto launch within the Lake Tahoe Basin should be inspected for AIS anddecontaminated at approved off-site washing stations prior to launching toprevent their introduction into the lake. This program is overseen by the LakeTahoe Aquatic Invasive Species Working Group (LTAISWG) 70 .Pollution prevention methods for controlling boating and marina relateddischarges include but are not limited to the following: material substitution,changes in operations or procedures, in-process recycling, off-site recycling,product or service change, and equipment modification. BMPs for each of thesemethods should include using a less toxic paint (e.g., water based instead ofsolvent based), storing chemicals under cover on impervious surfaces, usingbiodegradable antifreeze, and using dustless sanders that capture sandingparticles. 71Most non-domestic wastewaters generated by boat maintenance facilityoperators are considered industrial wastewater. Non-domestic wastewater,industrial wastewater, or other wastewater shall not be discharged into anysewer designated to carry stormwater or allowed to flow directly into surfacewaters. No industrial wastewater or other liquids shall be discharged tosanitary sewers. Some wastewater may be recycled or disposed of, but prior todisposal, it shall be treated to reduce the levels of concentrations of heavymetals (principally copper) and meet the standards for disposal in sanitarysewers as set by the state regulatory agencies and TRPA.A minimum of one lakeside pump-out installation shall be provided at allcommercial marinas and harbors. A pump-out facility consists of equipmentneeded to pump or otherwise receive and transfer contents of vessel holding70Check http://www.tahoercd.org for the latest information in inspection locations andrequirements.71B.C.
