Edwards Aquifer Protection Plans

Provides the definition of an Edwards Aquifer protection plan, 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.

The EAPP may include: a water pollution abatement plan, organized sewage collection system plan, underground storage tank facility plan, aboveground storage tank facility plan, contributing zone plan, or a modification, exception, or extension request granted by the executive director.

Why are these plans necessary?

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.

Who is required to prepare and submit an Edwards Aquifer protection plan?

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, including exclusions, can be found in 30 TAC 213.3(28) 30 TAC 213.22(6) for the contributing zone of the Edwards Aquifer Exit the TCEQ.

How do I know what forms to complete?

There are a number of forms that are required for each plan type. In order to help you figure out what forms are required, you can use the Edwards Aquifer Protection Plan Flowchart.
