UNPUBLISHED OPINION
CONNOLLY, Judge
Relator challenges respondent Minnesota Pollution Control Agency’s (MPCA)
issuance of a National Pollutant Discharge Elimination System/State Disposal System
(NPDES/SDS) permit, arguing that (1) the MPCA’s decision is arbitrary and capricious
because the effluent limit in the permit relies on significant voluntary pollution reductions
and the record lacks evidence that such reductions have been or will be achieved; and
(2) the permit violates federal law by allowing discharge of pollution in excess of
applicable water-quality standards. We affirm.
FACTS
Background
Although phosphorus occurs naturally in rivers and lakes, too much phosphorus can
cause an excessive growth of algae, resulting in the killing of fish and severe nuisance algae
blooms. There are two main sources of phosphorus pollution: point sources (e.g.
discharges coming from a pipe such as wastewater-treatment-plant outfalls) and nonpoint
sources (e.g., agricultural runoff and streambank erosion). The regulation of point and
nonpoint sources is at the heart of this dispute.
The Federal Clean Water Act (CWA) requires the states to adopt water-quality
standards (WQS) that “establish the desired condition of a body of water.” In re Cities of
Annandale and Maple Lake NPDES/SDS Permit, 731 N.W.2d 502, 510 (Minn. 2007).
2
WQS can be narrative, i.e., a description of unacceptable conditions in a water body, or
numeric, i.e., a quantitative measure of the concentration of a pollutant in a water body. In
re Alexandria Lake Area Sanitary Dist. NPDES/SDS Permit, 763 N.W.2d 303, 309 (Minn.
2009); Minn. Envt’l. Sci. and Econ. Review Bd. v. Minn. Pollution Control Agency, 870
N.W.2d 97, 99 (Minn. App. 2015). WQS are used to determine if a water body is
“impaired” under CWA § 303(d). 33 U.S.C. § 1313(d)(1)(A) (2014). After identifying an
impaired water body, a state must identify a total maximum daily load (TMDL) for each
pollutant that causes a failure to meet WQS. 33 U.S.C. § 1313(d)(1)(C) (2014). A TMDL
includes
the sum of pollutant load allocations for all sources of the
pollutant, including a wasteload allocation for point sources, a
load allocation for nonpoint sources and natural background,
an allocation for future growth of point and nonpoint sources,
and a margin of safety to account for uncertainty about the
relationship between pollutant loads and the quality of the
receiving surface water.
Minn. Stat. § 114D.15, subd. 10 (2014). WQS are also used to determine the appropriate
limits to be included in NPDES/SDS permits. 33 U.S.C. § 1342 (2014); 33 U.S.C.
§ 1311(b)(1)(C); 40 C.F.R. § 122.44(d) (2014). If a discharge has the reasonable potential
to cause or contribute to a violation of a water quality standard, a NPDES/SDS permit must
include a water-quality-based effluent limit (WQBEL). 40 C.F.R. § 122.44(d)(1)(iii)
(2014). It is undisputed that the NPDES/SDS permit at issue in this appeal was required
to have a WQBEL because, in 2001, the Lake Pepin watershed was placed on the impaired
waters list under CWA § 303(d) for excessive nutrients, particularly phosphorus.

The Dispute
The MPCA has the authority to implement the CWA in Minnesota. 33 U.S.C.
§ 1342; Minn. Stat. § 115.03, subd. 5 (2014). In 2014, the MPCA adopted numeric river
eutrophication1 WQS for Minnesota, including the Mississippi River Pool 3, that limited
total phosphorus (TP) to less than or equal to 100 Ug/L. Minn. R. 7050.0222. At the same
time, the MPCA adopted a site-specific eutrophication standard for Lake Pepin with similar
numeric standards. Minn. R. 7050.0220, subp. 7. These became the “applicable [WQS]”
for CWA purposes when the Environmental Protection Agency (EPA) approved them in
early 2015. See 40 C.F.R. § 131.21(c).
In May 2015, the MPCA published notice of its intent to issue a permit to respondent
Metropolitan Council Environmental Services (MCES) for five MCES wastewater
treatment plants. The notice consisted of an 18-page fact sheet describing the terms of the
permit and the MPCA’s rationale for issuing it. During the 30-day comment period, relator
Minnesota Center for Environmental Advocacy (MCEA) submitted comments opposing
the permit. The MPCA issued a response to the MCEA’s comments and, on September 11,
2015, issued the permit. The goal of the permit is “to reduce TP pollutant levels in point
source discharges and protect water quality in accordance with [state and federal law].”
MCEA petitioned for a writ of certiorari to challenge the issuance of the permit.

Eutrophication is a response to increased phosphorus loading that “is characterized by
increased growth and abundance of algae and other aquatic plants, reduced water
transparency, reduction or loss of dissolved oxygen, and other chemical and biological
changes.” Minn. R. 7050.0150.

DECISION
An agency’s quasi-judicial determinations will be upheld unless they are
unconstitutional, outside the agency’s jurisdiction, procedurally defective, based on an
erroneous legal theory, unsupported by substantial evidence, or arbitrary and capricious.
Carter v. Olmsted County Hous. and Redevelopment Auth., 574 N.W.2d 725, 729 (Minn.
App. 1998). “When a decision turns on the meaning of words in a statute or regulation, a
legal question is presented. In considering such questions of law, reviewing courts are not
bound by the decision of the agency and need not defer to agency expertise.” St. Otto’s
Home v. Minn. Dep’t of Human Servs., 437 N.W.2d 35, 39-40 (Minn. 1989) (citations
omitted). “When the agency’s construction of its own regulation is at issue, however,
considerable deference is given to the agency interpretation, especially when the relevant
language is unclear or susceptible to different interpretations. If a regulation is ambiguous,
agency interpretation will generally be upheld if it is reasonable.” Id. (citations omitted).
The appellate court will also defer to the agency’s expertise and special knowledge “when
(1) the agency is interpreting a regulation that is unclear and susceptible to more than one
interpretation; and (2) the agency’s interpretation is reasonable.” In re Annandale, 731
N.W.2d at 515. The appellate court will also “consider the agency’s expertise and special
knowledge when reviewing an agency’s application of a regulation when application of the
regulation is primarily factual and necessarily requires application of the agency’s technical
knowledge and expertise to the facts presented.” Id. n.9 (quotation omitted).

I. Was the MPCA’s issuance of the MCES permit arbitrary and capricious?
“[A]n agency ruling is arbitrary and capricious if the [] (a) [agency] relied on factors
not intended by the legislature; (b) [agency] entirely failed to consider an important aspect
of the problem; (c) [agency] offered an explanation that runs counter to the evidence; or
(d) [agency’s] decision is so implausible that it could not be explained as a difference in
view or the result of the agency’s expertise.” Citizens Advocating Responsible Dev. v.
Kandiyohi Cty. Bd. of Comm’rs, 713 N.W.2d 817, 832 (Minn. 2006). The MCEA argues
that the MPCA’s issuance of the permit was arbitrary and capricious because the MPCA
relied on speculative future events, specifically voluntary reductions in phosphorus
pollution from unregulated nonpoint sources, to conclude that the MCES’s limit will meet
eutrophication standards, thus violating the regulatory requirement that the MPCA
consider only existing point and nonpoint source controls.
When developing water-quality-based effluent limits, the permitting authority shall
ensure that the level of water quality to be achieved by established limits on point sources
is derived from, and complies with, all applicable WQS and that effluent limits developed
to protect a numeric water quality criterion are consistent with the assumptions and
requirements of any available wasteload allocation for the discharge prepared by the state
and approved by the EPA. 40 C.F.R. § 122.44(d)(1)(vii). The regulation MCEA cites for
support of its argument states that each NPDES permit must include: any requirement in
addition to, or more stringent than, promulgated effluent limitations, guidelines, or
standards necessary to achieve WQS under section 303 of the CWA, including state
narrative criteria for water quality, which includes limitations on pollutants which the
6
director determines are or may be discharged at a level which will cause, have the
reasonable potential to cause, or contribute to an excursion above any state WQS. 40
C.F.R. § 122.44 (d)(1).
(ii) When determining whether a discharge causes, has
the reasonable potential to cause, or contributes to an in-stream
excursion above a narrative or numeric criteria within a State
water quality standard, the permitting authority shall use
procedures which account for existing controls on point and
nonpoint sources of pollution, the variability of the pollutant or
pollutant parameter in the effluent, the sensitivity of the species
to toxicity testing (when evaluating whole effluent toxicity),
and where appropriate, the dilution of the effluent in the
receiving water.
40 C.F.R. § 122.44 (d)(1)(ii) (emphasis added). We conclude that this regulation is
irrelevant in determining whether a WQBEL in a permit is sufficient to meet WQS. 40
C.F.R. § 122.44(d)(1)(ii) applies in “determining whether a discharge causes, has the
reasonable potential to cause, or contributes to an in-stream excursion above a narrative or
numeric criteria within a state water quality standard.” It is undisputed that the discharge
has the reasonable potential to cause an in-stream excursion above numeric criteria. The
WQBEL was included specifically because of this reasonable potential to cause or
contribute to an excursion above the numeric criteria within a State water quality standard.
See 40 C.F.R. § 122.44(d)(1)(iii) (stating that “[w]hen the permitting authority determines,
using the procedures in paragraph (d)(1)(ii) of this section, that a discharge causes, has the
reasonable potential to cause, or contributes to an in-stream excursion above the allowable
ambient concentration of a State numeric criteria within a State water quality standard for
an individual pollutant, the permit must contain effluent limits for that pollutant.”)
7
While the WQBELs set out in a permit must be calculated to ensure that the
receiving waters meet WQS, they need not, in and of themselves, cure water quality
problems. Upper Blackstone Water Pollution Abatement Dist. v. U.S. E.P.A., 690 F.3d 9,
32-33 (1st Cir. 2012). Regulations require a permit to include conditions that “control all
pollutants or pollutant parameters . . . [that] are or may be discharged at a level which will
cause, have the reasonable potential to cause, or contribute to an excursion above any State
water quality standard.” 40 C.F.R. § 122.44(d)(1)(i). The MPCA must consider both point
and nonpoint sources of phosphorus pollution in setting effluent limits in a permit but the
fact that, by itself, the permit does not ensure that the receiving waters will meet WQS does
not render the MPCA’s permit arbitrary and capricious.2
MCEA argues that “MPCA’s reliance on hypothetical, voluntary reductions rather
than ‘existing controls’ on nonpoint sources runs afoul of federal regulations.”
Specifically, MCEA argues that the term “existing controls” means actual or real controls,
not hypothetical or future controls, that MPCA has failed to identify any existing controls
that will result in phosphorus reduction from nonpoint sources, and that the MPCA is not
authorized to “consider[] anticipated reductions from nonpoint sources.” But as we have
stated, the federal regulation does not limit the MPCA to only existing controls on point
and nonpoint sources in setting a WQBEL, only that existing point and nonpoint sources
must be considered when deciding if a WQBEL is necessary. Nothing in the regulation
2
MCEA’s argument that the effluent limit is not a WQBEL is not supported by the
evidence. MCEA’s claim that MPCA “put [the 159 metric tons per year] effluent target
for the facilities into a model, and used the model to dial down inputs from other sources
until the [WQS] were met” is not supported by the citation provided.
8
cited by relator limits the MPCA to looking at only existing controls on point and nonpoint
sources of pollution to determine if the WQS will be met after the MPCA determines that
a WQBEL is necessary.
However, our supreme court has not authorized or invited the MPCA to allow
discharge permits in cases involving offsets that are remote in either time or place. In re
Annandale, 731 N.W.2d at 525-26. It is therefore necessary for us to determine whether
there is substantial evidence in the record as to whether or not controls exist on nonpoint
sources and that based on these programs, it can reasonably be expected that future
reductions in nonpoint source pollution will occur. “Substantial evidence is defined as:
(1) such relevant evidence as a reasonable mind might accept as adequate to support a
conclusion; (2) more than a scintilla of evidence; (3) more than some evidence; (4) more
than any evidence; or (5) the evidence considered in its entirety.” Cannon v. Minneapolis
Police Dep’t, 783 N.W.2d 182, 189 (Minn. App. 2010) (quotation omitted).
MCEA argues that the record lacks substantial evidence of the scope of nonpoint
source reductions necessary to achieve future reductions, whether the quantity of
reductions is attainable, what actions are necessary to achieve those reductions, or any
support that the controls can be expected or anticipated. MPCA, in response to a similar
allegation in MCEA’s comments, stated “[n]onpoint source reductions have . . . been
achieved since the baseline period [1980 to 1996] and further improvements can reasonably
be expected to occur in the future.”
It is not the role of the court to decide if voluntary reductions are the best method,
rather, it is our role to examine the record to see if sufficient evidence exists to show that
9
reductions have occurred in the past and that they can reasonably be expected to occur in
the future. If such evidence exists, the decision to rely on them is not arbitrary and
capricious. We conclude that substantial evidence exists to conclude that voluntary
reductions from nonpoint sources have occurred in the past and can be reasonably expected
to occur in the future. The Nutrient Reduction Strategy (NRS), a document drafted by, in
addition to the MPCA and the MCES, the Minnesota Department of Agriculture, the
Minnesota Board of Water and Soil Resources, the Natural Resources Conservation
Service, the Farm Service Agency, the Minnesota Department of Natural Resources, the
Minnesota Department of Health, the Minnesota Public Facilities Authority, the University
of Minnesota, and the United States Geological Survey, provides substantial evidence of
existing state programs designed to achieve reductions in nonpoint source pollution as
evidence that reductions in nonpoint pollution have been achieved and can reasonably be
expected to continue to occur.
“A function of the [NRS] is to identify the nutrient reduction goals and milestones
and provide a path to achieve those reductions over time.” Nutrient-management efforts
have been ongoing for several decades. The NRS reports that reduction of phosphorus
pollution from nonpoint sources has resulted in an eight percent reduction of phosphorus
in the Mississippi River Basin since 2000. This is a result of several programs outlined in
chapter four of the NRS such as the Clean Water Land and Legacy Program,3 the Erosion
3
A program established in 2008 that uses appropriations from the Clean Water Fund
(CWF) to implement a number of clean-water-easement programs. The goal of the CWF
is to reduce nonpoint source pollution by providing CWF dollars to local government units
for on-the-ground activities.
10
Control and Water Management Program,4 the Regional and Local Resource Management
and Planning Programs,5 the Reinvest in Minnesota Reserve Program,6 the Agricultural
Best Management Practices Loan Program,7 the Farm Nutrient Management Assessment
Program, the Nonpoint Source Management Program,8 the Agricultural Fertilizer Research
and Education Council,9 the EQIP Mississippi River Basin Healthy Waters Initiative,10 as
well as several others. These programs still exist and can be expected to influence nonpoint
source pollution in the future. Each of these programs provide funding, education, or other
incentives to decrease nonpoint source pollution.
Additionally, chapter five of the NRS describes “practices and technology that can
be used to reduce phosphorus and nitrogen inputs to waters from key sources and presents
4
A program that provides funds to soil and water conservation districts to share the costs
of systems or practices for erosion control, sedimentation control, or water quality
improvements.
5
A number of programs through which nutrient-load reductions are addressed by
implementing regulations, developing plans, engaging the public and funding best
management practices.
6
A program that compensates landowners for granting conservation easements on privately
owned lands that are, amongst other things, highly erodible.
7
Water quality program that provides low interest loans to farmers, rural landowners and
agriculture supply businesses to encourage agricultural best management practices that
prevent or reduce runoff from feedlots, farm fields, and other pollution problems.

A program that allows Minnesota to receive nonpoint source grant funds from the EPA
under section 319 of the CWA. In 2011, these funds were used for developmental,
education, and research projects and TMDL implementation projects.

education that is environmentally and economically sound.
10

11
example scenarios projected to meet the nutrient reduction milestones.” The NRS
enumerates and prioritizes ways to achieve the phosphorus goals through various
combinations of best management practices (BMP):
1. Optimize fertilizer and manure rates based on soil test
phosphorus (estimated to provide a net savings to
producers).
2. Increase [the] use of conservation tillage with at least 30
percent residue where conservation tillage is not already
being used (estimated to provide a net savings to
producers).
3. Use precision application techniques such as subsurface
banding (net cost uncertain).
4. Add living cover BMP such as riparian buffers and cover
crops that currently have a net cost to producers.
The MCEA argues that, because the nonpoint source reduction strategies stated in
the NRS are voluntary, they are not sufficient controls on nonpoint source pollution to be
considered when granting a permit. The MPCA has shown that these nonpoint source
reduction strategies are reasonably likely to occur because they are in the best interest of
the nonpoint source polluters from a cost-savings prospective. The NRS represented the
cost-benefit results for agricultural best management practices and presented both the costs
and the benefits as annualized values. But the MPCA and Iowa State University developed
the annualized values by calculating the net present value of the monetary costs and
benefits associated with each practice from the producer’s point of view. The results found
in the NRS suggest that nonpoint source pollution strategies are likely to be implemented
because of the cost savings to the producers. Additionally, the programs outlined in this
opinion, as well as several others discussed in chapter four of the NRS, suggest that
voluntary reductions will continue to be made as a result of the incentives available to
12
nonpoint source polluters. We conclude that the NRS goals and implementation strategies
constitute substantial evidence to support MPCA’s view that nonpoint source pollution
improvements will continue to be made in the future.
II. Did the MPCA violate federal law when it issued the permit allowing the
MCEA wastewater-treatment facilities to discharge pollution in excess of WQS
applicable to the Mississippi River Pools and Lake Pepin?
Relator next argues that the permit does not comply with federal law because, even
if all of the nonpoint source reductions were achieved, phosphorus pollution would
continue to plague Lake Pepin and the Mississippi River Pools. The CWA requires the
MPCA to establish effluent limits that ensure a level of water quality that complies with
WQS. 33 U.S.C. § 1311(b)(1)(C); 40 C.F.R. §§ 122.44(d)(1)(ii), 122.44(d)(1)(vii).
Relator argues that the limits derived for the permit will not result in a level of water quality
that will achieve the recreational and aquatic-life use standards that apply to Lake Pepin
and the Mississippi River Pools because, by MPCA’s own admission, the modeled
reductions in phosphorus loading would not achieve WQS in 7 of the 22 years modeled.11
Relator primarily argues that the water conditions standards set forth in Minn. R.
7050.0222, subp. 4, 4(b) must be met every summer, not over a multiple-year average.
Minnesota’s eutrophication standards for Lake Pepin and the Minnesota River
Basin, “are compared to summer-average data.” Minn. R. 7050.0222, subp. 4(a). A
“summer-average” means a representative average of concentrations or measurements of
11
Relator states that phosphorus loading would not achieve WQS in 9 of the 22 years
modeled but according to the Lake Pepin Model outputs under Scenario 21, phosphorus
WQS is not predicted to be met in 7 out of the 22 years modeled.
13
nutrient enrichment factors, taken over one summer season, meaning a period annually
from June 1 through September 30. Minn. R. 7050.0150, subps. 4(DD), 4(EE). Therefore,
the standard is met if the phosphorus averaged over the summer months is less than the
numeric criterion in the rule. Minn. R. 7053.0205, subp. 7(c) states:
Discharges of total phosphorus in sewage, industrial waste, or
other wastes must be controlled so that the eutrophication
water quality standard is maintained for the long-term summer
concentration of total phosphorus, when averaged over all
flows, except where a specific flow is identified in chapter
7050.
(emphasis added).
The MPCA is the permitting authority charged with the day-to-day administration
of the CWA in Minnesota. Minn. Stat. § 115.03; 40 C.F.R. §123.25(a). The MPCA
established the TP limit for the permit based upon the results of its complex model which
demonstrated that the long-term summer concentration of TP, averaged over all flows, will
meet the numeric eutrophication standard. In so establishing, the MPCA found that
calculating effluent limits for river eutrophication standards is uniquely challenging
because “the seasonal averaging period for river eutrophication standards applies to all
summer days over multiple years (typically assessed over a 10 year period) so that there is
not a critical flow consideration . . . for river eutrophication standards as with conventional
pollutants and toxins.” Based on this finding, the MPCA used the average TP
concentration from all 22 years of the model to determine whether the numeric
eutrophication standard would be satisfied. Averaging over all 22 years, rather than
selecting a shorter range (the ten years recommended in the Statement of Need and
14
Reasonableness (SONAR)) ensured that the most complete range of flow conditions would
be factored into the determination of whether the standard would be met.
In arguing that the standard must be met each summer, relator quotes MPCA’s
SONAR in adopting site-specific standards for Lake Pepin and the Mississippi River,
which states “site-specific standards are applicable across all summers to ensure aquatic
recreational use is supported in all years.” However, the SONAR continues to say
[w]ith this in mind, site-specific standards for Lake Pepin and
Mississippi River navigational pools will be applied across all
summers with assessments using summer-means based on the
most recent 10 years, consistent with other 303(d) assessments.
An exception to the use of the complete 10-year record would
be if a significant trend were noted that could be associated
with specific point and nonpoint source reductions conducted
as a part of TMDL implementation. In that instance, a shorter
record (a minimum of two summers) could be used to assess
use-support.
Additional support can be found for the multi-year average in MPCA’s response to relator’s
comments to the draft permit:
Eutrophication standards are different from other standards in
that the target is a long-term average rather than a short-term
‘do not exceed’ type value. The assessment process for lakes
evaluates the long term water-quality by averaging summer
means over a 10-year period. Given the considerable impact
of annual weather patterns on the stream flows through Lake
Pepin, MPCA decided to use all 22 years of the modelling
effort to determine if reductions were adequate to meet the
standard.
We agree with the MPCA that “long-term summer concentration” refers to a period
of more than one summer. If the regulation’s intent was to focus on a single summer, the
defined term “summer average” would have been used. The phrase “long-term summer
15
concentration” evidences the intent of a different meaning. Because we conclude that the
plain language construction of “long-term summer concentration” refers to a period of time
longer than one summer, the MPCA did not act arbitrarily and capriciously in issuing the
permit.
Affirmed.
