Mo. Rev. Stat. § 701.046
Except as otherwise provided in section 701.031, no person may, on or after September 1, 1995, construct or make a major modification or major repair to an on-site sewage disposal system without first notifying the city, county or department and completing an application, upon a form provided by the department, and submitting a fee in the amount established by the city, county or department. The fee shall be set at an amount no greater than that necessary to cover the cost to implement the state standard for on-site sewage disposal systems and the registration of contractors. For areas of the state where the department is enforcing the state standard or registering contractors, the department shall establish the fee, by rule, at an amount not greater than ninety dollars. The department may charge an additional fee, as necessary, to cover the expenses of training those contractors electing to perform the percolation tests. The application form shall require such information necessary to show that the on-site sewage disposal system will comply with the state standard. Such fees, when collected by the department, shall be deposited in the state treasury to the credit of the Missouri public health services fund. The department shall provide technical assistance regarding the type and location of the system to be installed when processing applications received under sections 701.046 to 701.048 and 701.050. Fees collected by the department shall be deposited in the Missouri public health services fund created in section 192.900 and shall be used to implement sections 701.025 to 701.059 and for no other purpose.
