Subcommittee Purpose and Projects
The purpose of the Nonpoint Source (NPS) Task Force was to facilitate and formalize the groundwater NPS program in Texas and to provide support and guidance for the groundwater NPS management policy of the state. The primary goal of the Task Force was to prevent/abate NPS pollution of groundwater.
The Task Force was charged with ensuring consistency of activities with the Texas NPS Management Plan and the Groundwater Protection Plan. The Task Force provided input for the Nonpoint Source Pollution Management Program Annual Report to the EPA; updated the state NPS assessment of groundwater conditions and NPS management strategy for groundwater resources; facilitated the review and submission of NPS project proposals for the annual EPA Clean Water Act, Section 319 (h) funding cycle; and provided input related to groundwater to the TSSWCB and the TCEQ for their management plans.
A more detailed explanation of the Task Force’s goals was provided in its Task Force Charge.
