(a) The owner or operator of a facility with hazardous waste management units subject to the post-closure care requirements in 40 Code of Federal Regulations (CFR) Part 265, Subpart G, must submit his post-closure plan to the executive director at least 180 days before the date he expects to begin partial or final closure of the first hazardous waste disposal unit. The date when he expects to begin closure must be either within 30 days after the date on which the hazardous waste management unit receives the known final volume of hazardous wastes or, if there is a reasonable possibility that the hazardous waste management unit will receive additional hazardous waste no later than one year after the date on which the unit received the most recent volume of hazardous wastes. The owner or operator must submit his post-closure plan to the executive director no later than 15 days after:      
        (1) termination of interim status (except when a permit is issued to the facility simultaneously with termination of interim status); or       
        (2) issuance of a judicial decree or compliance order under the Resource Conservation and Recovery Act of 1976, §3008, as amended, or Texas Health and Safety Code, Chapter 361, to cease receiving wastes or close.       
      (b) Except as provided in subsection (c) of this section, the executive director will provide the owner or operator and the public, through a newspaper notice, the opportunity to submit written comments on the post-closure plan and request modifications of the plan, including modification of the 30-year post-closure period required in 40 CFR §265.117 within 30 days of the date of the notice. The owner or operator is responsible for the cost of publication. The executive director may, in response to a request or at his own discretion, hold a public hearing whenever a hearing might clarify one or more issues concerning the post-closure plan. The executive director will give the public notice of the hearing at least 30 days before it occurs. (Public notice of the hearing may be given at the same time as notice of the opportunity for written public comments and the two notices may be combined.) The executive director will approve, modify, or disapprove the plan within 90 days of its receipt. If the executive director does not approve the plan, he shall provide the owner or operator with a detailed written statement of reasons for the refusal and the owner or operator must modify the plan or submit a new plan for approval within 30 days after receiving such written statement. The executive director will approve or modify this plan in writing within 60 days. If the executive director modifies the plan, this modified plan becomes the approved post-closure plan. The executive director must ensure that the approved post-closure plan is consistent with 40 CFR §§265.117 - 265.120. A copy of this modified plan with a detailed statement of reasons for the modifications must be mailed to the owner or operator. If an owner or operator plans to begin closure before November 19, 1981, he must submit the post-closure plan by May 19, 1981.     
      (c) Post-closure plans submitted in an application for a post-closure order in accordance with §305.50(b) of this title (relating to Additional Requirements for an Application for a Hazardous or Industrial Solid Waste Permit and for a Post-Closure Order) must comply with the public notice and comment requirements specified in Chapter 39, Subchapter N of this title (regarding Public Notice of Post-Closure Orders).
