§ 245.234. Siting requirements.
(a) The Department will not issue a site-specific storage tank system or facility installation permit if:
(1) The installation of storage tank systems and facilities is proposed on 100-year floodplains or a larger area that the flood of record has inundated unless an industrial use on the proposed site was in existence as of August 5, 1989.
(2) The installation of storage tank systems and facilities is proposed in wetlands in a manner inconsistent with Chapter 105 (relating to dam safety and waterway management).
(3) The Department determines that construction design criteria or engineering specifications submitted by a professional engineer are not in accordance with generally accepted sound engineering practices or existing conditions at the site require mitigation to properly support the tank systems and the applicant’s proposed mitigation actions are not deemed adequate.
(b) The applicant shall provide the following additional information if appropriate:
(1) Over areas underlain by carbonate bedrock, the applicant shall provide information and analysis to the Department which assesses the prevalence of solution channels and the potential for sinkholes at the facility site.
(2) If any part of a proposed facility has been previously mined by deep mining methods, the applicant shall provide the results of an engineering study of the proposed site by a Pennsylvania registered professional engineer or Pennsylvania registered professional geologist. The study must be detailed enough to assess the potential for and degree of surface subsidence. The study must also include methods which have been used or will be used to stabilize the surface. The applicant shall provide assurance that minerals providing surface support will not be mined as long as the facility stores regulated substances.
(3) A professional engineer’s construction design criteria and engineering specifications necessary to mitigate surface or subsurface conditions which may result in excessive storage tank system settlement or unstable support of the applicant’s proposed storage tank systems.
