RE: Fuel Oil Ash Spec

Charlie,

Based on your response, copied below, on the ash content of the fuel required, and MHI's response, also copied below, identifying the ash limits to meet PM10 specifications, it appears there is not a problem.

Thanks,

Mike Coleman

Ash Content of the Fuel Available:

Mike,

The maximum ash content is 0.01 wt% on the official spec for low-sulfur #2 fuel oil that we would be ordering. We should plan on receiving fuel oil with up to this amount as you mention.

Thanks,

Charlie
