Extension Request

Requirements relating to a request for an extension of an Edwards Aquifer protection plan and the forms that are required.

The TCEQ’s approval of an Edwards Aquifer protection plan will expire two years after the date of initial issuance unless, prior to the expiration date, substantial construction related to the approved plan has commenced. Substantial construction means that more than 10% of total construction has commenced. The definition of substantial construction can be found in 30 TAC 213.4(h) Exit the TCEQfor the recharge and transition zones and in 30 TAC 213.23(g) Exit the TCEQ for the contributing zone of the Edwards Aquifer.

Note: An Edwards Aquifer protection plan will expire and no extension will be granted if more than 50% of the total construction has not been completed within ten years from the initial approval of a plan.

An extension request must be received before the plan expires, but not more than 60 days before the expiration date of the approved protection plan or a previously approved extension. If an extension request is received after the expiration date of an approved protection plan or previously approved extension, then the request cannot be approved and a new application with appropriate fees will be required. Also, we cannot grant an extension if the proposed regulated activity or approved plan has changed.

The approved extension will expire six months after the original expiration date of the approved plan or the last approved extension.

The fee for each extension request is $150. For additional information on fees, view the Application Fee Form TCEQ-0574 (PDF, Word), which includes a complete fee schedule.

The forms listed below are grouped by Recharge and Transition Zones or Contributing Zone. Use the applicable forms to prepare your exception request.
