(a) The purpose of this subchapter is to regulate by rule the removal, containment, treatment and disposal of wastes occurring at commercial livestock trailer cleaning facilities. Certificates of registration issued under this chapter are subject to Chapter 50, Subchapter G of this title (relating to Action by the Executive Director). The requirements of this subchapter apply to only those livestock trailer cleaning facilities that are described in both paragraphs (1) and (2) of this subsection:
  (1) The facility is commercial. A facility is "commercial" if the owner or operator provides trailer cleaning services to other persons for profit, or provides such service in conjunction with other services.
  (2) The facility utilizes evaporation ponds, storage pond(s) or other pond(s) with land application as a means of treatment and disposal.
(b) The requirements of this subchapter do not apply to other livestock trailer cleaning facilities.
(c) A livestock trailer cleaning facility that is subject to the requirements of this subchapter must also comply with other commission rules, if applicable.
(d) Executive director authorization by a registration issued pursuant to this subchapter is not required if untreated facility wastewater is either discharged or transported to a POTW which has a wastewater permit issued by the agency.
(e) Regardless of the applicability of subsection (a) of this section, a livestock trailer cleaning facility that is otherwise subject to the requirements of this subchapter, but which is a component of a feedlot or concentrated animal feeding operation regulated under the requirements of this chapter or regulated by permit as provided by Chapter 305 of this title (relating to Consolidated Permits), is not subject to the requirements of this subchapter.
(f) If the executive director denies a registration application under this subchapter, the facility must obtain a permit pursuant to the Texas Water Code, Chapter 26.
(g) New livestock trailer cleaning operations are prohibited from being registered under this rule when located on the Edwards Aquifer Recharge Zone. New livestock trailer cleaning operations located on the Edwards Aquifer Recharge Zone are required to submit an application for permit to the agency's Wastewater Permits Section (MC 148).
