Re: Ordinance Regulating the Sale of Phosphorus-Free Fertilizer
PURPOSE
New state legislation regulates the use of turf fertilizers, but not its sale. If a
local ordinance regulating the sale of turf fertilizers is not in place by August
1, 2002, the sale of turf fertilizers containing phosphorus will not be regulated
in the City of Chanhassen. The following report is a summary of the issue and
a proposed ordinance.
BACKGROUND
Most lawn fertilizers contain three primary nutrients utilized by plants:
nitrogen (N), phosphorus (P) and potassium. (K). If the phosphorus applied to
lawns is not used by plants or does not adhere to the soil, it is washed away
and can flow overland into ponds, creeks, wetlands and lakes. Sometimes
fertilizer is spilled onto driveways, sidewalks and roadways and swept away
by rain into storm sewers. Some people also dispose of fertilizer by pouring it
into storm sewers.
Phosphorus is the favorite nutrient of algae and duckweed. When excess
phosphorus enters a water body, the algae and duckweed in that water body
grow very quickly. As algae and duckweed die, the plant material
decomposes. The decaying plant material emits a foul odor and
decomposition uses dissolved oxygen from the water. Low dissolved oxygen
levels can kill off desirable game fish, leaving only rough fish that are able to
survive in low oxygen environments.
Most of the soils in Chanhassen are naturally high in phosphorus, so most
lawns do not need fertilizer with phosphorus to stay healthy and green. Many
Chanhassen residents do not know this, so they apply a fertilizer with

phosphorus at least once a year. Many people also fall victim to the "more is better"
theory of lawn care. This leads them to apply more fertilizer than necessary in hopes of
attaining a beautiful lawn.
WHY IS PHOSPHORUS A PROBLEM?
High phosphorus levels are a concern for the City for several reasons:
io
Large algae and duckweed blooms can be indicators of water bodies that are in poor
health. Chanhassen has a long history of clean lakes. Protecting and improving water
quality will enrich Chanhassen's biological, social and economic environments.
.
People who live near Chanhassen's water bodies have expectations of how the water
body will look and smell (or not smell). City staff receives many calls each year
about the aesthetics of ponds, creeks, wetlands and lakes. Few "quick fix" solutions
are available. If the City commits to addressing high phosphorus levels on a citywide
level, both citizens and staff would benefit.
o
High phosphorus levels lead to more algae. As the algae decompose, they leave
material in outlet structures and ponds, which results in decreased storm water pond
capacity. Since storm water ponds need a certain capacity to fulfill their water quality
and quantity functions, the City must make sure the ponds can handle that capacity.
With more material in the ponds, the City must maintain ponds frequently. Frequent
pond maintenance represents a significant cost to the City.
LEGISLATION
In April 2002, the Minnesota Legislature passed a statute regulating fertilizers containing
phosphorus. This statute bans the use of phosphorus fertilizers within the seven-county
metropolitan area except in specific instances. In the rest of the state, it restricts fertilizer
use to low-phosphorus types (3% phosphate by weight). These restrictions go into effect
on January 1, 2004 and preempt any existing local ordinances. Attached is a copy of the
new state fertilizer law (Chapter 345-S.F. No. 1555).
The law reserves the state's right to regulate the sale of lawn fertilizers, but does not do
so. The City will only have the ability to regulate the sale of lawn fertilizers if a local
ordinance is in effect on August 1, 2002.
RECOMMENDATION
A local ordinance regulating the use of fertilizers with phosphorus is unnecessary since
the new state law will address that need. The law allows local governments to regulate

the sale of turf fertilizers if such regulations are in place on August 1, 2002. The
adoption of an ordinance to regulate the sale of lawn fertilizers would be beneficial since
the new state law does not specifically address the sale of fertilizers.
Staff recommends the City Council approve the following motion:
"Chapter 10 of the Chanhassen City Code shall be amended by adding Article VII to
read:
Article Vii. Sale and Display of Lawn Fertilizers
Sec. 10-200. Sale and display of lawn fertilizer.
No person, firm, corporation, franchise, or commercial establishment shall sell or
display for sale any lawn fertilizer, liquid or granular, within the City of Chanhassen that
contains any amount of phosphorus or other compound containing phosphorus, such as
phosphate, unless:
(1) Phosphorus-free fertilizer is also available for sale.
(2)
Phosphorus-flee fertilizer and fertilizer with phosphorus are separately
displayed with each display being clearly marked as to whether or not the
fertilizer contains phosphorus.
(3)
Displays of phosphorus-free fertilizer are of equal or greater size and
prominence."
