Allegheny County Executive Dan Onorato today vetoed a bill to sell the Health Department's administrative office building because of an amendment that tightly controlled how the sale proceeds could be spent.

Onorato said the amendment puts the bill in violation of the county home rule charter. It would leave the county with an unbalanced budget and the special reserve fund it creates is not mentioned in the bill's title, both violations of the charter, according to Onorato.
