The No Surcharge Alliance in California has grown to  more than 100 banks, 300 credit unions, and 2,600 automated teller   machines, said Robert Rose, president and chief executive officer of Credit   Union Cooperative Systems Inc.     
In February, a charter group, consisting of the credit union cooperative  and six banks, headed by Union Bank of California, announced the No   Surcharge Alliance in response to decisions by BankAmerica Corp. and Wells   Fargo & Co. to charge noncustomers $1.50 to use their ATM networks. Credit   unions, banks, and thrifts have continued to join the alliance.       
  
Recently the Independent Bankers Association of California, which  represents more than 200 small financial institutions, endorsed the   alliance. So did Scripps Bank, an independent commercial bank in La Jolla.   
"The alliance will continue to grow as large regional banks attempt to  gain market share by surcharging the consumer," said Mr. Rose. "The   alliance provides a good option for consumers and particularly credit union   members."
