Dams on navigable streams
This bill also creates an additional exemption to the requirement that a person
maintaining a dam on a navigable stream must allow at least 25 percent of the
natural low flow of water of the stream to pass through the dam. Under current law,
this requirement does not apply to a dam where the water is discharged directly into
a lake, mill pond, storage pond, or cranberry marsh, or to cases in which the DNR
determines that the required minimum discharge is not necessary for the protection
of fish life. Under the bill, this requirement also does not apply to a dam in a fish farm
where the water is returned to the navigable stream.

WPDES permits
This bill clarifies what conditions DNR may include in a Wisconsin Pollutant
Discharge Elimination System (WPDES) permit issued to a fish farm.
Under current law, DNR must include in WPDES permits issued to certain
large fish farms requirements that are based on certain provisions under federal law.
Those provisions require fish farms to use specified best-management practices
relating to discharging solids, storing materials, and inspecting and maintaining
production and wastewater treatment systems.
This bill requires DNR to include the federal requirements in all WPDES
permits issued to fish farms. The bill also prohibits DNR from including additional
conditions in a permit issued to a fish farm unless those conditions are necessary to
meet certain standards, such as federal or state water quality standards or schedules
of compliance established by DNR. The bill also states that any condition that is
included in a permit issued to a fish farm must be based on site-specific best
management practices to the greatest extent allowed under federal law.
Variances to water quality standards
The bill also specifies certain information that DNR must use in deciding
whether to grant a variance to a fish farm.
Current law allows a WPDES permittee to request a variance from applicable
water quality standards. Under current federal regulations, any variance granted
by DNR must also be reviewed and either approved or disapproved by the federal
environmental protection agency (EPA). This bill states that, when deciding
whether to grant a variance to a fish farm, DNR must rely on the same guidance
documents and other information that would be used by EPA in reviewing the
variance.
Water withdrawals under the Great Lakes Compact
The bill also provides that if a fish farm withdraws water and places it in an
aquacultural pond that is registered with the Department of Agriculture, Trade and
Consumer Protection (DATCP), any subsequent withdrawal of that water from that
pond is not a "withdrawal" for purposes of the Great Lakes Compact. The Great
Lakes Compact generally prohibits water from within the Great Lakes basin from
being diverted out of the basin and imposes certain requirements on a person who
withdraws 100,000 gallons of water per day or more from the Great Lakes basin.
Cost-sharing exemption from nonpoint performance standards
Current law requires DNR to promulgate rules setting performance standards
for sources of nonpoint water pollution, which is water pollution from diffuse sources.
Under current law, the owner or operator of an agricultural facility or practice that
existed before October 14, 1997, is exempt from complying with these nonpoint
performance standards unless cost-sharing is available to the owner or operator
under the soil and water resource management program administered by DATCP or
the nonpoint source pollution abatement financial assistance program administered
by DNR. This bill adds aquaculture to the list of activities that make up "agricultural
practice" and that are associated with an "agricultural facility" in this context.

Agricultural use in the Lower Wisconsin State Riverway
Under current law, a person may develop or use land in the Lower Wisconsin
State Riverway for agricultural use if the development and use comply with the rules
for the soil and water resource management program promulgated by DATCP. This
bill adds aquaculture to the list of activities that make up "agricultural use" in this
context.
WHEDA loan guarantees
Under current law, the Wisconsin Housing and Economic Development
Authority administers the Wisconsin Development Reserve Fund (WDRF) to provide
loan guarantees to farmers and other small businesses. Current law provides that
a loan made to a farmer to finance the acquisition of agricultural assets or the cost
of improvements to facilities or land, which are acquired or made for agricultural
purposes, is eligible for a guarantee from the WDRF. This bill expands the type of
loans that are eligible for this guarantee to include loans made to acquire assets used
in aquaculture and loans that are made for aquacultural purposes.
Navigable water permits
This bill also exempts aquacultural uses of land from the requirement to obtain
a permit from DNR to construct, dredge, or enlarge an artificial water body that
connects with a navigable waterway or that is located within 500 feet of the ordinary
high-water mark of an existing navigable waterway, or to grade or remove more than
10,000 square feet of topsoil from the bank of a navigable waterway.
Transportation of agricultural products
Finally, this bill allows the Department of Transportation to issue permits for
the transportation of fish and minnows in vehicles that exceed certain weight
limitations.
For further information see the state fiscal estimate, which will be printed as
an appendix to this bill.
