WASHINGTON - With comments due today, small banks around the country  are flooding the government with letters endorsing a proposed 83% cut in   their deposit insurance premiums.   
Few of the 1,600 letters filed with the Federal Deposit Insurance Corp.  so far are from large banks, which typically submit their responses at the   last minute.   
  
On Jan. 31, the agency announced its plans to reduce Bank Insurance Fund  premiums to 4#1/2 cents from 23 cents per $100 of deposits for the second   half of 1995. The FDIC said it plans to leave thrift premiums at the 23-   cent level.     
While big banks often offer dispassionate analysis of every aspect of an  agency proposal, community bankers speak briefly and from the heart. 
  
"I thought I truly must be dreaming when I heard that the FDIC had  proposed a new average premium rate of 4#1/2 cents," wrote Donna Perine,   president and chief executive of Farmers and Merchants Bank, a $15.2   million-asset institution in Harrisville, W. Va. "Please don't pinch me and   wake me up if it really is only a dream."       
The letters show virtually unanimous support for reducing bank premiums  and strong opposition to any use of banks' money to help the thrift   industry, whether through a merger of BIF and the Savings Association   Insurance Fund or otherwise.     
For small banks, the issue is fairness. Banks replenished the bank fund  on their own and deserve a premium reduction, they argued. Thrifts should   bear the cost of recapitalizing the thrift fund and retiring the government   bonds issued to finance the S&L bailout.     
  
"Not one thin dime of taxpayer money went to restore the BIF," wrote  Robert E. Sorem, chairman and chief executive of Sylvan State Bank in   Sylvan Grove, Kan. "There is no moral or legal reason bank assessments   should go to meet SAIF requirements or Fico bond retirement."     
Many letters emphasized the benefits the premium reduction would bring  to communities. 
"For the year ended 1994, Apollo Trust Co. paid $202,208.58 in  premiums," wrote Helen J. Clark, president of the Apollo, Pa., bank. The   reduction would mean "an increase to net income of $77,978, some of which   can be reinvested into the community."     
Letters from thrifts warned that lowering bank fund premiums without  reducing thrift premiums would confer an unfair competitive advantage on   banks.   
  
"Commercial banks can be expected to react to lower FDIC premiums by  raising deposit rates and cutting loan fees - forcing thrifts with higher   premiums to match bank rates, hurting their profitability and ability to   compete," wrote Joseph C. Scully, chairman of St. Paul Bancorp, a Chicago   thrift company.       
Some small banks suggested that the FDIC ease the thrifts' pain by  reducing their premiums to 18 basis points, transferring unused Resolution   Trust Corp. funds to SAIF, and using "Oakar-Sasser" premiums for Fico bond   payments.     
"Current SAIF members did not cause the prior SAIF fund losses and,  therefore, should not be subjected to an unfair burden of total fund   recapitalization," wrote David Ballweg, president of Community State Bank   in Union Grove, Wis.
