John, As per our discussion.

Bob

♦ This analysis does not include HVAC/exhaust systems that EPA has identified as potentially needing a cleanup. In addition, this analysis does not take into account the numbers and the size of apartments currently enrolled in the Indoor Residential Cleanup Program. In summary, we anticipate an under-run of 20 million dollars against Ae original allocation. This number is fluid and the savings could be higher.
