Edwards Aquifer Protection Plans

Defines Edwards Aquifer protection plans, explains why they are necessary, and outlines who is required to prepare and submit them to the TCEQ.

What is an Edwards Aquifer protection plan?

An Edwards Aquifer protection plan (EAPP) outlines the best management practices that will be implemented and maintained, both during and after construction activities, to prevent contaminants found in storm water from reaching the Edwards Aquifer.

These plans are necessary to ensure that steps are taken to protect groundwater and maintain Texas Surface Water Quality Standards in areas that will impact the Edwards Aquifer.

If you plan to conduct a regulated activity (such as construction, land clearing, aboveground or underground storage tank installation) over the Edwards Aquifer, you must submit your plan to the TCEQ for approval prior to disturbing soil at the site.

A complete list of regulated activities for the contributing zone of the Edwards Aquifer, including exclusions, can be found in both 30 TAC 213.3(28) and 30 TAC 213.22(6)Exit the TCEQ.

There are a number of forms that are required for each plan type. In order to help you figure out what forms are required, visit Edwards Aquifer Protection Plan: What Forms You Might Need.

You can find additional information on the Edwards Aquifer Protection Program Web page.
