conservative strength parameters in the modeled profile and is consistent with analysis
requests made by DMG personnel on past submittals. Due to the conservative strength

provide reasonable assurances that nearby structures will not be harmed by site mining
activities.

easements, or as surveyed by pipe location markers provided by the utility companies. The

requirements, and that all underground utilities shall be located prior to mining. This note
