Prior to the IGD, the ESP was included as part of the site work plans. The IGD reiterates the approving authorities for Army ESP documents, which includes the DoD component (USACE), the U.S. Army Technical Center for Explosives Safety (USATCES), and the DDESB. According to the IGD, an ESP must be approved "before activities involving the use, exposure to, disposal of, or placement of, explosives on the site."
The IGD also reiterates the situations where an ESP is not required by the Army (i.e. emergency responses, Preliminary Assessments / Site Inspections where no intrusive activities are planned, operational range clearance, small arms only ranges, on-call construction support activities, and anomaly avoidance activities).
