§ 84-63.1004. Hazard score.

(a)

Formula. The hazard score of a proposed development project shall be determined pursuant to the following formula:

[(T + C + P) × H] + D + A;

where the following symbols have the following designations:

"T" refers to the point assignment for "Transportation Risk";

"D" refers to the point assignment for "Community Risk - Distance from Receptor";

"C" refers to the point assignment for "Community Risk - Type of Receptor";

"A" refers to the point assignment for "Facility Risk - Size of Project - Total Amount";

"P" refers to the point assignment for "Facility Risk - Size of Project - Percent Change"; and

"H" refers to the point assignment for "Hazard Category of Material or Waste."

(b)

Project Hazard Score. If more than one category of hazardous material or hazardous waste is used, the formula set forth in this section will be used to calculate a separate score for each material category. The material hazard category which results in the highest hazard score for the project will be used.

(c)

Point Assignment. The factors set forth in subdivision (a) of this section, shall have the following point assignments:

TRANSPORTATION  RISK (T)	POINTS
Truck — residential/commercial (>25% increase or new)	10

(d)

Credit for Reductions or Projects to be Closed. A development project that would have a hazard score of eighty or more as determined by the formula in this section shall be entitled to a reduction credit for project closures and/or reductions in accordance with the criteria set forth in this subdivision. Reduction credit shall be given if the community development director determines that the applicant will concurrently close another project or reduce its operations and finds that all of the following criteria are met:

(1)

The project to be closed or reduced is in the same facility in which the development project is proposed;

(2)

The project to be closed or reduced is currently in operation and has been in operation for at least three years prior to the date of application, during which period the production schedule has been reflective of a normal production schedule;

(3)

The project to be closed or reduced is the direct result of the proposed development project;

(4)

The project to be closed or reduced has a higher hazard score than the proposed development project;

(5)

The hazard category of the material or waste in the development project will be no greater than the hazard category of the material or waste in the project to be closed or reduced; and

(6)

The development project will be more than three hundred feet from the property line of the nearest residential property or sensitive receptor.

The hazard score for the project to be closed shall also be determined by the formula set forth in subsections (a) and (b) of this section and pursuant to the provisions of this article. In determining the hazard score for the project to be closed or reduced, said project shall be deemed a new project.

The hazard score of the development project shall be subtracted from the hazard score of the project to be closed or reduced. The resulting difference will then be subtracted from the hazard score of the development project to obtain a hazard score adjusted for the closure or reduction. The adjusted hazard score shall be the basis for determining whether a land use permit shall be required under this chapter.

A determination by the community development director that a project is not subject to the land use permit requirement of this chapter as a result of credit afforded for a project closure or reduction shall be reported to the zoning administrator pursuant to Section 84-63.808 and shall be subject to the public notification requirements set forth in Section 84-63.801.

(e)

Closure, Reduction Required. Projects proposed for closure or reduction for which closure or reduction credit was afforded under this section shall be closed or reduced as proposed within one year of completion of the development project. This subsection (e) applies only in cases where a land use permit would have been required but for the closure or reduction credit afforded under this section.
