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.
Required Application
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 $500;
the maximum, $5000.
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.
