a. The RCUZ program is established to guide land use recommendations in the vicinity of RTAs to support current and future Marine Corps training, testing, and operational requirements and to protect the public health, safety, and welfare of Marines, Sailors, their families, and the general public. This is accomplished through the development of, and periodic updates to, RCUZ studies, establishment of RCZs, and noise analysis for aircraft operations as well as A-G, G-A, and G-G ordnance firing, with or without laser use, with the resulting weapons impact and detonation.

b. The RCUZ Program identifies RCZs, based on a composite of Surface Danger Zones (SDZs), Weapons Danger Zones (WDZs), and Laser Surface Danger Zones (LSDZs), and additional protections for safe ordnance delivery and aircraft overflight. Reference (b) establishes Marine Corps range safety policies and addresses the establishment of SDZ, WDZ, and LSDZ, all of which can be created through tools in the Range Manager’s Tool Kit (RMTK). SDZs and WDZs identify hazardous areas that result from the firing and/or delivery of weapons and ordnance on all Marine Corps ranges, and LSDZs depict where laser radiation levels may exceed maximum permissible exposure levels, thereby requiring control during laser operations.

c. The RCUZ Program requires that the Installation Commander's Encroachment Management Program work to prevent incompatible land uses adjacent to military training ranges. These land areas are typically identified as part of an installation RCUZ study (or other installation planning study) and can be addressed with encroachment management tools discussed in Enclosure (2) and reference (c).
