Analysis by the Legislative Reference Bureau
This bill directs the Department of Natural Resources to establish a wetland
assured delineation program.
Current law generally prohibits the discharge of dredged or fill material into
a wetland unless a person is issued a wetland general permit or individual permit
by DNR. Under current law, a person who owns or leases land may use the following
methods to delineate the boundaries of a wetland in a manner recognized by DNR:
1) the person may request that DNR provide a wetland identification to determine
if wetlands are located on a parcel, or part of a parcel, that does not exceed five acres;
2) the person may have a third person prepare a wetland delineation and request
that DNR confirm the boundaries of the wetland as delineated by that third person,
based on DNR's on-site inspection of the land; or 3) with respect to nonfederal
wetlands, the person may have a qualified third person perform a wetland
identification delineating the boundaries of a wetland and request DNR to confirm
those boundaries, not based upon an on-site inspection of the land but rather based
on a review of maps, aerial photographs, surveys, wetland delineations, and
hydrophytic soil conditions. Under current law, nonfederal wetlands are wetlands
that are not under the jurisdiction of the federal government, and a qualified third

person is an individual who has completed basic and advanced wetland training and
has a minimum of one year of field experience in wetland delineation.
The bill adds a wetland assured delineation program as a fourth method for
delineating the boundaries of a wetland in a manner recognized by DNR. Under the
program, a person may apply to DNR to be certified as an assured delineator. A
wetland delineation prepared by an assured delineator has the same effect as a
wetland identification or confirmation prepared by DNR, and a wetland delineation
prepared by an assured delineator need not be confirmed by DNR. Under the bill,
DNR must charge a $1,200 annual certification fee to an assured delineator, must
require a report of each wetland delineation an assured delineator prepares, and
may charge a filing fee not to exceed $20 for each report submitted. The bill provides
that a wetland delineation prepared by an assured delineator is effective for five
years from the date upon which the wetland delineation report is submitted to DNR.
This matches the effective period for wetland identifications and confirmations of
federal wetlands provided by DNR under current law.
The bill requires DNR to establish application and qualification requirements
for assured delineator certification but includes some minimum requirements, such
as at least five years of full-time professional field experience in wetland delineation
and completion of a wetland delineation training course based on the U.S. Army
Corps of Engineers wetland delineation manual. The bill also requires DNR to
charge an application processing fee of $500. The bill provides that an applicant
whose application is not approved may reapply and requires DNR to accept
applications no less than annually and at least during the period beginning
September 15 and ending November 30 for applicants who wish to be certified
beginning on March 15 of the next calendar year.
The bill requires DNR to review the performance of assured delineators on a
recurring basis and authorizes DNR to perform in-field audits of specific wetland
delineations performed by assured delineators. The bill allows DNR to investigate
any person's complaint that an assured delineator may be violating program
requirements. The bill allows DNR to gather—or to require a permit holder or
applicant to provide—additional wetland delineation data if DNR receives a
complaint alleging inaccuracies in a wetland delineation completed by an assured
delineator or if DNR finds inaccuracies in a wetland delineation report. If the
additional data show substantial evidence that a wetland delineation is inaccurate,
the bill allows DNR to use the data for regulatory decision-making, including
wetland permitting and exemption decisions. However, under the bill DNR may not
modify a permit or exemption decision solely on the basis of this additional data.
The bill allows DNR to revoke a person's certification as an assured delineator
if it finds the person did any of a list of actions, for example knowingly falsifying or
misrepresenting a wetland boundary. Under the bill, a person whose assured
delineator certification has been revoked is entitled to a contested case hearing.
Under the bill, DNR must consider a person who is approved or certified as an
assured delineator under an existing pilot program as certified as an assured
delineator under the program created in the bill.

an appendix to this bill.
