How do you stop Washington ER Portion of MLI to be taken from Pay check

PeopleSoft 9.2 North American Payroll

WA does not require payment of Employer portion of MLI (medical leave insurance) if you have less than 50 Employees. How do you prevent the Employer portion from being taken in the Employee's Paycheck. The Employee's portion still needs to be taken. Setting the EE portion to 100% on the Company State Tax table will not work because the Employee's portion remains the same at 45%.
