§ 22.10.050. Explosives Storage.

The storage of explosives is allowed only for the purpose of sales by a licensed vendor, or where the explosives will be used on the same site as the storage facility, as provided in this Section.

A.

Applicability. The standards of this Section apply in addition to all applicable state and federal standards, including any regulations administered by the County Health Department, Fire Department, Sheriff's Office, Agricultural Commissioner, and Air Pollution Control District. If any standards of this Chapter conflict with regulations administered by other federal, state, or county agencies, the most restrictive standards apply.

B.

Permit requirement. Conditional Use Permit approval within an urban or village reserve line; Minor Use Permit approval in rural areas. Separate land use permit approval is not required where the principal use of the site has been authorized through Conditional Use Permit approval, or in the case of a surface mining operation, where the operation has been authorized by an approved reclamation plan. This permit requirement is in addition to the permit required by the County Sheriff.

C.

Location. Explosives storage is allowed only in the Agriculture, Rural Lands or Industrial land use category, or areas included within an Energy and Extractive Resource (EX) combining designation. A land use permit application that proposes explosives storage may be approved only where the Review Authority finds the proposed site is within an area that is open in character and essentially free of development.

D.

Setbacks. Explosives storage shall not be located closer than 1,000 feet from any property line, except that storage in Class II magazines, as authorized in State law, shall not be located closer than 400 feet from any property line; provided that where the current edition of the Uniform Fire Code adopted by the County would require a greater setback than required by this Section, the greater setback shall apply.

E.

Construction and buffering. Explosives storage shall be effectively screened by a natural landform or artificial barricade either surrounding the entire site or surrounding each storage magazine. Storage magazines shall be designed and constructed in compliance with the current edition of the Uniform Fire Code adopted by the County, and any applicable requirements of the County Sheriff. The landform or barricade shall be of such height that.

1.

A straight line drawn from the top of any side wall of all magazines to any part of the nearest building or structure will pass through the landform or barricade; and

2.

A straight line drawn from the top of any side wall of all magazines to any point 12 feet above the centerline of a railroad or a public street will pass through said landform or barricade.

Artificial barricades shall be a mound or rivetted wall of earth with a minimum thickness of three feet.

F.

Time limit. Land use permit approval for storage of explosives may be granted for a maximum of five years, provided that the land use permit shall be subject to review by the Review Authority at any time. If, through such review, the Review Authority finds that circumstances or conditions have changed so the use no longer meets the requirements of this Section or the conditions of the land use permit, the permit may be revised or revoked, whichever is more appropriate.
