A. 
A sewer connection fee shall be charged to the owner of the property at the time a building permit is requested with work described to be new building space or a modification to existing building space which will result in increased wastewater flow or a connection to the common sewer, or an application for a sewer connection or change of use is filed with the Sewer Commission. The sewer connection fee shall be paid prior to the issuance of a building permit. Each building space within a building or structure shall be assessed a separate sewer connection fee. Changes in a building space which result in increased wastewater flow [as set forth in 310 CMR 15.00 (Title V)] will be charged a connection fee for the increased flow.
B. 
Calculation of fee.
(1) 
The Four Corners Sewer District sewer connection fee shall be calculated as follows: For new connections, use, the daily waste water flow shall be calculated using design flow figures contained in 310 CMR 15.203 (or its successor). This figure shall be divided by 330 gal/day and the result shall be known as the "equivalent residential unit" (ERU). If the result is less than one, the result shall be rounded up to one. All other results shall be the actual number as calculated to the fourth decimal place. For example: A four-bedroom house has a flow of 440 gal/day. 440/330 = 1.3333. The ERU is 1.3333. The ERU shall be multiplied by the then-current minimum connection fee and the product shall be the sewer connection fee.
(2) 
For the Four Corners Sewer District connection fee for changes in building space use which will result in increased flow, the increase shall be determined using the design flow figures contained in 310 CMR 15.203 (or its successor), and subtracting the current use design flow from the proposed use design flow. The increase shall be divided by 330 gal/day and the result shall be known as the "equivalent residential unit" (ERU). For example: A four-bedroom house has a flow of 440 gal/day. 440-330 = 110; 110/330 = 0.3333. The increased ERU is 0.3333. All results shall be the actual number as calculated to the fourth decimal place. The increased ERU shall be multiplied by the then-current minimum connection fee and the product shall be the sewer connection fee. Changes in building space use which will result in a decreased flow shall not be subject to a sewer connection fee; nor shall any such decreased flow result in a refund of any previously paid sewer connection fee.
C. 
The Four Corners Sewer District Sewer connection fee shall be the fee which is in effect at the earliest time a building permit is requested, or an application for a sewer connection or an application for change of use is filed with the Sewer Commission.
D. 
The amount of the Four Corners Sewer District sewer connection fee for each operational year shall be set by the Sewer Commission, or its successors, after a public hearing.
E. 
The Sewer Commission, after a public hearing, notice of which is given at least two weeks prior to the hearing, may waive or reduce the connection fee or any other fees if it determines in its sole discretion that it is in the interest of the users of the Four Corners Sewer System to do so.
