22activities occurring on the agricultural land shall execute a
23water quality plan. The commissioners shall assist the owner
24or operator in developing the plan. The person executing the
25plan shall file the plan with the commissioners subject to
26their approval. A copy of the plan shall be delivered to the
27division. An updated plan must be filed and approved each
28three years in the same manner as the original plan.
   292.  a.  A person is not required to file a water quality plan
30until December 31, 2021.

   323.  The water quality plan shall apply to the same farm unit
33as an applicable farm unit conservation plan or conservation
34agreement. The plan may be made part of the farm unit
35conservation plan or soil conservation agreement. However,
-2-1a plan may cover one or more farm units as specified in the
2plan so long as all farm units are located as part of the
3same district. The plan shall identify those water quality
4practices or farming practices that manage nutrients and
5reduces contributing contaminant loads to receiving surface
6waters as required under this section.
   74.  The water quality plan shall be completed on forms
8prepared by the division in consultation with the Iowa nutrient
9research center established pursuant to section 466B.47.
10The plan shall be based on an analysis of the nutrient loss
11potential of a farm’s farming practices and water quality
12practices by the water quality model established by the Iowa
13nutrient research center pursuant to section 466B.52. The plan
14must provide that the farm unit’s nutrient load contribution to
15surface water sources shall not exceed its assigned tolerance
16values for nitrogen or phosphorus. The plan shall account for
17all of the following:
   18a.  The location of each field and its size in acres.
   19b.  The proximity of the field to a water source, including
20any major water source.
   21c.  The amount and timing of nutrients or commercial
22fertilizers applied to each field.
   23d.  Whether the application occurs on snow-covered ground or
24frozen ground.
   25e.  If the farm unit includes an animal feeding operation,
26whether the animal feeding operation is a confinement feeding
27operation as defined in section 459.102 or an open feedlot
28operation as defined in section 459A.102. For each animal
29feeding operation, the plan shall state the type of animals
30confined, and the animal unit capacity of the operation.
   31f.  The maintenance of any water quality practice, soil and
32water conservation practice, or erosion control practice.
   33g.  The types of farming practices utilized.
   34h.  Whether the agricultural land has been subject to soil
35erosion in excess of the applicable soil loss limits.
   1i.  The predicted loads of nitrogen and phosphorus
2respectively contributed to a surface water source, including
3a major water source, and the extent that such loads are less
4than the tolerance values assigned to that farm unit.
   5j.  The results of a test conducted according to a schedule
6adopted in the plan that indicates the average loads of
7nitrogen and phosphorus respectively being contributed to a
8surface water source, including a major water source. The test
9shall be conducted by the division, the commissioners, or a
10person approved by the division or the commissioners.
   115.  The commissioners shall ensure that a person receiving
12financial assistance under this chapter is complying with the
13terms and conditions of the water quality plan.
   146.  The commissioners shall inspect or cause to be inspected
15agricultural land covered by a water quality plan, if
16reasonable grounds exist to believe that a failure to comply
17with the plan is occurring. If the commissioners determine
18a failure is occurring, a notice of that finding shall be
19delivered to the person who filed the plan, to the landowner or
20landowners of record, and to each occupant of the agricultural
21land if known to the commissioners. The notice shall describe
22the agricultural land affected and shall describe the failure.
23The notice shall also describe the corrective action required
24and the time limit for commencing and accomplishing such
   267.  If corrective action has not been commenced or
27accomplished as described in the notice, the commissioners
28shall issue an administrative order to the person who filed the
29water quality plan. The administrative order shall address the
30same subjects provided in the notice. However, the corrective
31action must be commenced not more than six months after the
32date the order is issued and must be completed not more than
33one year after that date.
   348.  The commissioners shall petition the district court
35to issue an order requiring immediate compliance with an
-4-1administrative order if the commissioners have determined any
2of the following:
   3a.  The corrective action has not been commenced or completed
4by the date specified in the administrative order.
   5b.  The corrective action has been commenced but is not
6being performed with due diligence or in a manner that will
7reasonably result in compliance with the water quality plan.

7   Sec. 6.  NEW SECTION.  466B.52  Iowa nutrient research center
8— crop field water quality model.
   91.  Not later than July 1, 2020, the center shall establish
10a crop field water quality model based on the policy objective
11described in section 466.51. The center shall establish the
12model in cooperation with other entities, including all of the

5farm fields based on the goals of the center normalized to a
6crop field level basis.
8The inclusion of this explanation does not constitute agreement with
9the explanation’s substance by the members of the general assembly.
   10This bill requires a water quality plan to be executed by
11a person as a condition to receiving financial assistance for
12establishing a soil and water conservation practice. The plan
13would cover water quality practices such as land use changes
14or the establishment and maintenance of a measure that limits
15sediment or nutrients from being conveyed by surface water
16runoff or leaching. It would also cover farming practices
17regarding crop production, including those associated with
18tillage. A water quality plan must be executed by the owner
19of agricultural land or an operator managing the farming
20activities occurring on the agricultural land. The plan is
21to develop in cooperation with the commissioners of the soil
22and water conservation district where the agricultural land is
23located. However, a plan is not required to be filed until
24December 31, 2021. The plan must be based on a crop field water
25quality model required to be developed by the Iowa nutrient
26research center with the objective that the contribution of
27nonpoint sources of nutrients occurring on agricultural land
28must be reduced by 41 percent for nitrogen and 29 percent for
29phosphorus. The commissioners must conduct inspections to
30ensure compliance with the plan and take administrative or
31judicial action to enforce its provisions.
