The following are exemptions to the prohibitions described in this chapter:
A. The prohibition against the use of fertilizer containing phosphorus shall not apply to turf and lawn areas for which soil tests confirm the ambient phosphorus content is below median phosphorus levels for typical area soils. The scope of this exemption shall only be for such volume or concentration of phosphorus necessary to permit such turf or lawn area to contain phosphorus levels equal to the median phosphorus levels for typical area soils. Phosphorus applied as fertilizer pursuant to this exemption shall be integrated into the soil where it is immobilized and generally protected from loss by stormwater runoff.
B. The prohibition contained in section 5-6-2 of this chapter shall not apply to any farming or agricultural business, provided the use of fertilizer is related to the growth of a product or maintenance of growing fields. Appropriate steps shall be taken to integrate the fertilizer into the soil where it is immobilized and generally protected from loss by stormwater runoff. This exemption shall not apply to the standard lawn area of said farm or agricultural business. (Ord. 07-10-25, 10-15-2007, eff. 1-1-2008)
