(a) Based on the proposals set forth in the feasibility study, the presumptive remedy, or other similar study, elements from different remedial action alternatives as proposed in a remedial investigation as well as any other information available to the executive director, the executive director shall select a proposed remedial action. After the selection of the proposed remedial action, the executive director shall hold a public meeting to discuss the proposed action, as required by the Act, §361.187. This meeting is not a contested case hearing within the meaning of Texas Government Code, Chapter 2001. Persons desiring to submit comments are encouraged to do so prior to the public meeting. Written comments should be submitted to the executive director at least 5 days prior to the date set for public meeting. All other comments shall be presented in the public meeting.
(b) This subsection describes the administrative procedures for modifying the proposed remedial action after the date of the initial public meeting to discuss the remedial action for the site.
  (1) A minor change in the proposed remedial action is one that does not significantly affect the scope, performance, or cost of the proposed remedial action. The executive director will document minor changes in the project records without the necessity of another public meeting.
  (2) A significant change in the proposed remedial action is one that materially affects the scope, performance, or cost of the proposed remedial action, but uses the same approach and results in a remedial action as least as protective as originally proposed. For significant changes, the executive director shall notify the PRPs by certified mail of the changes and issue a public notice in the Texas Register and in a newspaper of general circulation in the county in which the facility is located. The notice shall provide information regarding the significant changes in the proposed remedial action; however, a public meeting or opportunity for public comment is not required. If the commission has not entered into an administrative order to perform the remedial action, a significant change will extend the schedules provided in the Act, §361.187(d).
  (3) A fundamental change in the proposed remedial action is one that uses a different approach to achieve the remedial action goals, or one that uses the same approach, but results in a remedial action that is less protective than that originally proposed. A major change in technology to address the contamination is a fundamental change. For fundamental changes, the executive director shall hold another public meeting to discuss the proposed changes in accordance with the Act, §361.187, and as described in subsection (a) of this section. This newly proposed remedial action shall supersede the remedial action originally proposed in the initial public meeting.
(c) Engineering documents submitted in connection with the remedial action must be approved by the executive director and must demonstrate compliance with relevant cleanup standards, except as provided in the Act, §361.193. The scope of these documents will depend on the nature and complexity of the proposed remedial action and may vary from facility to facility.
(d) The executive director shall establish the minimum requirements for the remedial design, based on the specific characteristics of the facility and the remedial action. If appropriate, the executive director may waive any of the requirements in this subsection for a particular facility. Typical remedial design requirements include, but are not limited to:
  (1) remedial action drawings and specifications;
  (2) quality assurance project plan;
  (3) sampling and analysis plan;
  (4) spill/release contingency plan;
  (5) implementation schedule; and
  (6) an operations and maintenance plan.
(e) A health and safety plan shall be prepared that addresses the protection of on-site personnel and the public from potential hazards particular to a facility while implementing the remedial action.
(f) All engineering plans and specifications prepared for remedial activities must be prepared and submitted in accordance with the Texas Engineering Practice Act.
