A proposal to add 10 percent or $1.8 million to the annual fee Philadelphia Gas Works pays to the city has been put off until the fall, according to city officials.

The measure, proposed last month by Councilman Curtis Jones Jr. as a means to generate additional revenue for the cash-strapped city, was approved by the Public Property and Public Works Committee on June 6.

But the bill was greeted skeptically by Councilwoman Marian B. Tasco, the chairwoman of the Philadelphia Gas Commission. Jones agreed to table the measure until the fall, when council reconvenes after its summer recess.
