Section 335.551 - Purpose, Scope, and Applicability(a) Purpose. This subchapter specifies the information and procedures necessary to demonstrate compliance with the three risk reduction standards of § 335.8 of this title (relating to Closure and Remediation).(b) Scope. The requirements of this subchapter will, when adequately carried out, assure adequate protection of human health and the environment from potential exposure to contaminants associated with releases from solid waste management facilities or other areas. Cleanup levels are specified for different types of contaminated media such as air, surface water, groundwater, and soil, and for cross-media contamination pathways such as soil to groundwater and soil to air. General procedures based on scientific principles are provided or referenced by these regulations so that specific numeric cleanup levels can be generated. The commission will periodically review the general procedures and revise these regulations as necessary.(c) Applicability. The requirements of this subchapter apply to persons who undertake a closure or remediation in accordance with § 335.8 of this title (relating to Closure and Remediation) during the period from June 28, 1993, until May 1, 2000, unless the person qualifies for an extended period of time as specified in § 335.8(a) of this title (relating to Applicability) for submission of a final report to be reviewed according to this subchapter. If the executive director denies approval of the final report for reasons of technical inadequacy, the executive director may require the person to comply with the requirements of Chapter 350 of this title (relating to Texas Risk Reduction Program). For closures and remediations initially reported to the executive director on or after May 1, 2000, the person shall use the procedures of Chapter 350 of this title in place of this subchapter.30 Tex.
