Thus any ;pilled <br />oil or diesel which did make it to tF,e bottom of the aline yard <br />would be trapped in the ponds. It is virtually impossible for a <br />spill to rear_h any natural surface waters. <br />These features do provide, what I wo,ald r_onsider, substantial <br />proter_tion from surface water contamination. Orr the other hand, <br />if the containment plan is to protect the groundwater as well as; <br />surface water this may not the case since nearly all ruaterial <br />from any spill would infiltrate into the soil. <br />Before I prepare the documentation for an exemption or proceed <br />with the containment plan I would like your opinion on whir_h way <br />to go. <br />Sincerely, <br />~~ <br />Don R.
