025 Pa. Code § 250.708. Postremediation care attainment.

§ 250.708. Postremediation care attainment.

(a)  After engineering controls are in place and the groundwater concentration levels have stabilized following any effects from the remediation, a statistical test shall be used to demonstrate that regulated substances in groundwater do not exceed the selected standard at the point of compliance. A statistical trend analysis, knowledge of the plume stability, or other acceptable method shall be used to demonstrate that contaminant concentration at the point of compliance will not exceed the selected standard in the future.
(b)  If engineering or institutional controls are utilized at a site to maintain the nonresidential Statewide health standard or the site-specific standard, a postremediation care program shall be implemented to protect human health and the environment.
(c)  A person implementing engineering controls shall ensure the ongoing achievement of the performance standards in order to maintain attainment.
(d)  A person shall implement a postremediation care plan, as identified in an approved final report.
(e)  A person may terminate postremediation care as approved in the final report if the person can demonstrate attainment under this chapter without the engineering controls in place, and document a fate and transport analysis that shows the standard will not be exceeded in the future.
