Permits and Authorizations

Review Section 1.4.4. All underwater detonations require prior approval due to military, environmental, or legal reasons. Federal, State, and local agencies must be contacted. The highest Navy authority has mandated that all Navy activities comply with environmental regulations:

• Navy Fleet Commanders have issued amplifying instructions for underwater detonation requirements.

• Obstruction or alteration of U.S. navigable water requires authorization via the Army Corps of Engineers.

• Local and State officials have their own specific requirements that must be adhered to, contact:

- State Oil and Gas Commission

- State Land Commission County Board of Supervisors

- City Police

- Fire Marshal

- City Engineer

• Environmental concerns include disruption/destruction of marine life and all forms of pollution. An environmental impact statement is required for any operation that could adversely effect the environment (see Section 1.4.4).

• Contact Fish and Game Commission.

2.7.3 Equipment

In addition to equipment required for the actual demolition work, other types of equipment are required for underwater operations. Equipment lists are provided in

NAVSEA SW061-AA-MMA-010, Chapter 8. These include:

• Demolition equipment

• Salvage accessories

• Salvage equipment

2.7.4 Technique

All factors must be considered when selecting the best explosives for a particular job. Inspection dives are needed to accurately determine site conditions that relate to technique selection. NAVSEA SW061-AA-MMA-010 lists characteristics of most conventional military explosives as well as selection criteria to be used in Chapter 4 (see Table 4-2). Examples of techniques for most applications used by the UCTs are also described in Chapters 11 through 16 of the NAVSEA document. Yet, another good source for underwater demolition techniques is the Army Field Manual FM 5250, Chapters 3 and 4.

As a general rule in planning explosives operations such as cutting steel, wood, and timber, test shots should be done in advance of the operation to determine the best methods and techniques to do the task. The test shots will also serve to identify potential hazards that could be encountered during the operation, such as the size of the ground or water shock wave and how it effects surrounding structures, barges, boats, etc.

2.7.5 Standard Operating Procedures (SOPs)

SOPs are required for all detonations involving bulk charges by NAVSEA OP 5, Vol 1, Rev 5, Chapter 2. All personnel involved must be familiar with the SOP and their specific responsibilities and duties. The SOP will include:

• Description of duties for all involved personnel.

• Description of team organization.

• Safety analysis.

• Operating procedures.

• Identification of medical facilities, emergency access routes, representatives, and responsibilities.

• Emergency procedures, telephone numbers, and contacts.

• Casualty procedures.

• Prefire procedures.

• Misfire procedures. 2.7.5.1 Incident Reporting.
