Water Pollution Abatement Plan
A water pollution abatement plan (WPAP) is required for any regulated activity proposed on the Edwards Aquifer recharge zone. This includes any construction-related activity on the recharge zone, such as, but not limited to:
- the construction of buildings, utility stations, roads, highways, railroads;
- clearing, excavation, or any other activities that alter or disturb the topographic, geologic, or existing recharge characteristics of a site; or
- any other activities which may pose a potential for contaminating the Edwards Aquifer and hydrologically connected surface streams.
The forms for a complete WPAP specify additional information that must be attached such as maps, site plans, geologic assessment, construction notes and details, calculations for the removal of suspended solids, and the sizing for permanent best management practices.
The fee is based on the project area in acres, and the type of development (one single-family dwelling; multiple single-family residential or parks; and nonresidential). The minimum fee is $650; the maximum, $10,000.
A WPAP must be submitted for review and approved prior to the commencement of construction or other regulated activies.
WPAPs are not required in the Edwards Aquifer recharge zone for existing sites, unless the sites are being modified. Also, a WPAP is not required for projects in the Edwards Aquifer transition zone.
