An SCS plan is a detailed plan that outlines best management practices that will be implemented in order to protect water quality when an organized SCS is constructed in the Edwards Aquifer recharge zone.

You are required to submit an SCS plan if you plan to construct an SCS over the recharge zone of the Edwards Aquifer.

An SCS plan must go through the application submission and review process and be approved prior to the commencement of construction.

The fee is assessed at $0.50 per linear foot. The minimum fee is $650; the maximum, $6,500. For additional information on fees, view the Application Fee Form TCEQ-0574 ( PDF, Word), which includes a complete fee schedule.
