Table 5 of the VGP (Residual Biocides and Biocide Derivative Monitoring Requirements) identifies monitoring requirements for residual biocides and biocide derivatives. Derivatives are noted with an asterisk (*) in that table. Two biocides, chlorine and chlorine dioxide, are included in one row of Table 5 to reflect that the BWTS monitoring requirements are identical for each of the four disinfection byproducts or derivatives (chlorite, chlorate, total trihalomethanes, and haloacetic acids) . However, the BWTS residual biocide monitoring requirements in Table 5 apply only to the specific biocide (chlorine or chlorine dioxide) used in that BWTS. As such, in addition to the four disinfection byproducts/derivatives, residual biocide monitoring is required for TRO (as chlorine) for any chlorine-based BWTS. Similarly, residual biocide monitoring is required for the four disinfection byproducts/derivatives and chlorine dioxide for any chlorine dioxide-based BWTS. [links]

EPA does not specifically require that a lubricant have received a label from one of the programs listed. However, EPA believes that the labeling programs mentioned in the permit identify existing EALs that generally meet the VGP requirements.

Under the NPDES regulations, if a vessel is owned by one person but is operated by another, it is the operator's duty to obtain a permit. 40 CFR §122.21(b). For the purposes of the Vessel General Permit, an "operator" is any "party . . . who (1) has operational control over vessel activities, including the ability to modify those activities; or (2) has day-to-day operational control of those activities that are necessary to ensure compliance with the permit or to direct workers to carry out activities required to comply with the permit." See VGP Definitions in Appendix A.

The VIDA empowered the USCG as the primary enforcement agency but this new law also modified the Clean Water Act to provide EPA and the states with authority to enforce the federal requirements established under the VIDA.

Information about the use of EALs should be recorded and kept in a log on the vessel, consistent with the recordkeeping requirements in Part 4 of the VGP. Vessel operators must document in their recordkeeping documentation either the EAL(s) they are using or why they are unable to use an EAL until the next dry docking and report the use of non-EALs in their Annual Report (see Part 2.2.9 of the VGP). When assessing compliance with use of EALs, EPA could require documentation that lubricants used by the vessel either meet the approved labeling requirements or have undergone and met the requirements through independent testing. This could include material safety data sheets (MSDSs) or other technical data sheets provided by the vendor that clearly document results of such labeling or testing. It is up to the vessel owner/operators to demonstrate compliance with this provision.

The inner (cooler portion) is pressed into the outer housing. Where these units join, they are sealed with O-rings. To separate the two pieces you need to press the cooler out of the housing. If you don't have a press, you can use a vise with a wood pusher on the center of the cooler and shims against the edges of housing base. Slow, even pressure along with some PB Blaster should seperate the two. Look for O-ring failure and/or corrosion adjacent to and under the O-ring. here

Lost about 4 quarts of oil in a few hours on Sunday in 2005 DF140. Searched the forum, appears first place to look is at the oil cooler. Then the oil cooler does leak, is it obvious? If I remove the oil cooler, should I be able to see where it is leaking?

Could the oil filter gasket have worked loose from the cooler and dumped the oil? [links]

With regard to visually seeing why it is leaking, yes, if you take the cooler apart while it is on the bench. If you go to the Suzukzi Parts link above and open the oil filter page for your engine you will see a diagram showing the cooler. more

However, I can't imagine you could lose that much oil that fast through the cooler o-rings. It would require a massive failure of the cooler casting pumping all the oil out the exhaust. Did you notice oil in the water with your exhaust water?

I noticed a slight oil sheen in my stbd. exhaust water flow at idle. This after about 120 miles at cruise (1,850rpm) returning to USA. There is no water in my lube oil, nor in my transmission oil. Did not need to add any fluids on the enire trip. So the only fluid not accounted for is likely to be diesel. Engines ran fine, got full rpm, no smoke, no apparent cylinder miss. Before I pull the fuel cooler to check for a leak I thought I would ask for ideas. Engines are 550 hp DD 6-92TA, 19 years old. 1,500 hrs. Heat exchangers rebuilt two years ago, but not the fuel coolers. I think these coolers are pretty rugged, but I'm willing to check on one to see.

The engines sounded fine. No smoke at all, even during my brief runs at full throttle to clear the carbon. I had noticed the sheen prior to leaving, but in my eagerness to go wrote it off to sitting in storage, figuring a good run would clear everything out. Ran about 200 nmi at cruise from Ft. Lauderdale to Eleuthera, another 70 or so to the Abacos, then hull speed around there for two months then on to West End, Grand Bahama. Then 1,850 rpm for the 70 or so nmi back to Ft. L which should have cleared all the carbon out. On arrival noticed no improvement in the sheen. [links]

If your car’s exhaust drips water out of the tailpipe, there’s no reason to necessarily panic. Your car’s exhaust does exactly what it sounds like it does, expels things. Gases, vapors, and all the other byproducts created by your car’s normal operation have to exit the vehicles inner workings eventually, and they do that through the exhaust.

WARNING: When water is running from your exhaust after your car has been running for a period of time, you should be concerned. [links]

If liquid coming from your tailpipe has a sweet smell, like maple syrup, this could be a sign of a more serious engine problem.
