Aligned: EPA Military Munitions Rule, DoD 6055.9-M, RCRA/CERCLA
Select the single best answer unless otherwise indicated. For Select All That Apply questions, choose all
correct options. Apply Military Munitions Rule provisions, RCRA hazardous waste regulations, DoD 6055.9-
M safety standards, and EPA environmental compliance frameworks.
Domain 1: MMR Foundations (Questions 1–5)
1. What was the primary purpose of the EPA’s Military Munitions Rule (40 CFR 266, Subpart
M), finalized in 1997?
A. To establish new explosive safety standards for all DoD facilities
B. To clarify when military munitions become hazardous waste under RCRA Subtitle C
C. To replace DoD 6055.9-M with a unified federal standard
D. To prohibit the use of open burn/open detonation for all munitions
Correct Answer: B
Rationale: The Military Munitions Rule was promulgated by EPA in 1997 primarily to clarify the
regulatory status of military munitions under RCRA Subtitle C. Prior to the rule, RCRA did not clearly
address when munitions transition from being military items to being regulated hazardous waste, creating
compliance uncertainty for the DoD.
2. Which of the following categories of munitions does the Military Munitions Rule apply to?
A. Only conventional munitions used by the Army
B. Both conventional and chemical munitions across all military services
C. Only chemical munitions requiring special storage
D. Only small arms ammunition and pyrotechnics
Correct Answer: B
Rationale: The MMR applies broadly to both conventional and chemical munitions across all branches of
the military. This inclusive scope ensures that all military munitions, regardless of type or service branch,
are subject to the same regulatory framework when determining their status as solid or hazardous waste.
3. Under the Military Munitions Rule, which regulatory framework governs the cleanup of
contaminated sites where munitions were used or disposed?
A. RCRA Subtitle C only
B. DoD 6055.9-M
C. CERCLA (Comprehensive Environmental Response, Compensation, and Liability Act)
D. The Clean Water Act
Correct Answer: C
1
, Rationale: CERCLA, also known as Superfund, is the primary federal law governing the cleanup of
contaminated sites, including former military ranges and disposal areas. While RCRA Subtitle C addresses
hazardous waste management prospectively, CERCLA addresses the remediation of historical
contamination from munitions use and disposal.
4. Why was the Military Munitions Rule necessary given that RCRA already existed?
A. RCRA explicitly exempted all military activities from environmental regulation
B. RCRA did not clearly address when military munitions become solid or hazardous waste
C. RCRA only applied to commercial hazardous waste, not government-generated waste
D. The DoD requested a separate regulatory framework to avoid EPA oversight
Correct Answer: B
Rationale: RCRA’s general hazardous waste provisions did not clearly define the point at which military
munitions transition from being usable military items to being regulated waste. This regulatory gap
created uncertainty about compliance obligations, prompting EPA to develop the MMR as a targeted
amendment to 40 CFR 266.
5. DoD 6055.9-M is best described as which of the following?
A. An EPA regulation governing munitions disposal methods
B. A state-level environmental compliance manual for military installations
C. The DoD Ammunition and Explosives Safety Standards manual
D. A CERCLA implementation guide for range cleanup
Correct Answer: C
Rationale: DoD 6055.9-M is the Department of Defense Ammunition and Explosives Safety Standards
manual. It establishes safety criteria for the storage, handling, and transportation of ammunition and
explosives at DoD facilities. While it complements the MMR, it is a DoD safety document rather than an
EPA environmental regulation.
Domain 2: Hazardous Waste Determination (Questions 6–12)
6. Under the Military Munitions Rule, when do unused military munitions become solid
waste?
A. When they are transported between military installations
B. When the military declares an intent to discard them or they are designated as waste
C. When they reach their expiration date regardless of condition
D. When they are stored for more than 90 days in any facility
Correct Answer: B
Rationale: Under the MMR, unused military munitions become solid waste when the military declares an
intent to discard them or formally designates them as waste. This “intent-to-discard” determination is the
critical regulatory trigger that transitions munitions from being military items to potentially regulated
hazardous waste.
7. What distinguishes serviceable from unserviceable unused munitions under MMR
regulatory analysis?
A. Serviceable munitions have been fired; unserviceable munitions have not
B. Serviceable munitions are still usable for their intended purpose; unserviceable munitions are
damaged or deteriorated
C. Serviceable munitions are always exempt from RCRA; unserviceable munitions are always
hazardous waste
D. There is no regulatory distinction between serviceable and unserviceable munitions
