Texas Health and Safety Code - HEALTH & SAFETY § 772.403. Implementation of 9-1-1 Service and Fee

(a) A county to which this subchapter applies may implement a system for providing 9-1-1 service in the unincorporated areas of the county and may impose a service fee on local exchange telephone service customers in the area served.

If a business service user provides residential facilities, each line that terminates at a residential unit and that is a communication link equivalent to a residential local exchange access line shall be charged the 9-1-1 emergency service fee.

(b) The commissioners court shall set the fee in an amount reasonable to cover the costs of providing the 9-1-1 service.

(c) Revenue from the fee may be used only for the planning, development, and provision of 9-1-1 service.
