____________________________________)

Under our state Constitution, if the Legislature or a state agency requires a 

local government to provide a new program or higher level of service, the local 

government is entitled to reimbursement from the state for the associated costs. 

(Cal. Const., art. XIII B, § 6, subd. (a).) There are exceptions, however. Under 

one of them, if the new program or increased service is mandated by a federal law 

or regulation, reimbursement is not required. (Gov. Code, § 17556, subd. (c).) 

The services in question here are provided by local agencies that operate 

storm drain systems pursuant to a state-issued permit. Conditions in that permit 

are designed to maintain the quality of California‘s water, and to comply with the 

federal Clean Water Act. The Court of Appeal held that certain permit conditions 
2

were federally mandated, and thus not reimbursable. We reverse, concluding that 

no federal law or regulation imposed the conditions nor did the federal regulatory 

system require the state to impose them. Instead, the permit conditions were 

imposed as a result of the state‘s discretionary action. 

I. BACKGROUND

The Regional Water Quality Control Board, Los Angeles Region (the 

Regional Board) is a state agency. It issued a permit authorizing Los Angeles 

County, the Los Angeles County Flood Control District, and 84 cities 

(collectively, the Operators) to operate storm drainage systems.

1 Permit 

conditions required that the Operators take various steps to reduce the discharge of 

waste and pollutants into state waters. The conditions included installing and 

maintaining trash receptacles at transit stops, as wells as inspecting certain 

commercial and industrial facilities and construction sites. 

Some Operators sought reimbursement for the cost of satisfying the 

conditions. The Commission on State Mandates (the Commission) concluded

each required condition was a new program or higher level of service, mandated 

by the state rather than by federal law. However, it found the Operators were only 

entitled to state reimbursement for the costs of the trash receptacle condition, 

because they could levy fees to cover the costs of the required inspections. (See 

discussion, post, at p. 12.) The trial court and the Court of Appeal disagreed, 

finding that all of the requirements were federally mandated. 

We granted review. To resolve this issue, it is necessary to consider both 

the permitting system and the reimbursement obligation in some detail. 

A. The Permitting System

The Operators‘ municipal storm sewer systems discharge both waste and 

pollutants.

2 State law controls ―waste‖ discharges. (Wat. Code, § 13265.) 

Federal law regulates discharges of ―pollutant[s].‖ (33 U.S.C. § 1311(a).) Both 

state and later-enacted federal law require a permit to operate such systems.

California‘s Porter-Cologne Water Quality Control Act (Porter-Cologne 

Act or the Act; Wat. Code, § 13000 et seq.) was enacted in 1969. It established 

the State Water Resources Control Board (State Board), along with nine regional 

water quality control boards, and gave those agencies ―primary responsibility for 

the coordination and control of water quality.‖ (Wat. Code, § 13001; see City of 

Burbank v. State Water Resources Control Bd. (2005) 35 Cal.4th 613, 619 (City of 

Burbank).) The State Board establishes statewide policy. The regional boards 

 

2 The systems at issue here are ―municipal separate storm sewer systems,‖ 

sometimes referred to by the acronym ―MS4.‖ (40 C.F.R. § 122.26(b)(19) 

(2001).) A ―municipal separate storm sewer‖ is a system owned or operated by a 

public agency with jurisdiction over disposal of waste and designed or used for 

collecting or conveying storm water. (40 C.F.R. § 122.26(b)(8) (2001).) Unless 

otherwise indicated, all further citations to the Code of Federal Regulations are to 

the 2001 version. 
4

formulate and adopt water quality control plans and issue permits governing the 

discharge of waste. (Building Industry Assn. of San Diego County v. State Water 

Resources Control Bd. (2004) 124 Cal.App.4th 866, 875 (Building Industry).)

The Porter-Cologne Act requires any person discharging, or proposing to 

discharge, waste that could affect the quality of state waters to file a report with 

the appropriate regional board. (Wat. Code, § 13260, subd. (a)(1).) The regional 

board then ―shall prescribe requirements as to the nature‖ of the discharge, 

implementing any applicable water quality control plans. (Wat. Code, § 13263, 

subd. (a).) The Operators must follow all requirements set by the Regional Board. 

(Wat. Code, §§ 13264, 13265.) 

The federal Clean Water Act (the CWA; 33 U.S.C. § 1251 et seq.) was 

enacted in 1972, and also established a permitting system. The CWA is a 

comprehensive water quality statute designed to restore and maintain the 

chemical, physical, and biological integrity of the nation‘s waters. (City of 

Burbank, supra, 35 Cal.4th at p. 620.) The CWA prohibits pollutant discharges

unless they comply with: (1) a permit (see 33 U.S.C. §§ 1328, 1342, 1344); (2) 

established effluent limitations or standards (see 33 U.S.C. §§ 1312, 1317); or (3) 

established national standards of performance (see 33 U.S.C. § 1316). (33 U.S.C. 

§ 1311(a).) The CWA allows any state to adopt and enforce its own water quality 

standards and limitations, so long as those standards and limitations are not ―less 

stringent‖ than those in effect under the CWA. (33 U.S.C. § 1370.)

The CWA created the National Pollutant Discharge Elimination System 

(NPDES), authorizing the Environmental Protection Agency (EPA) to issue a 

permit for any pollutant discharge that will satisfy all requirements established by 

the CWA or the EPA Administrator. (33 U.S.C. § 1342(a)(1), (a)(2).) The federal 
5

system notwithstanding, a state may administer its own permitting system if 

authorized by the EPA.

3 If the EPA concludes a state has adequate authority to 

administer its proposed program, it must grant approval (33 U.S.C. § 1342(b)) and 

suspend its own issuance of permits (33 U.S.C. § 1342(c)(1)).

4 

California was the first state authorized to issue its own pollutant discharge 

permits. (People of St. of Cal., etc. v. Environmental Pro. Agcy. (9th Cir. 1975) 

511 F.2d 963, 970, fn. 11, revd. on other grounds in Environmental Protection 

Agency v. California (1976) 426 U.S. 200.) Shortly after the CWA‘s enactment, 

the Legislature amended the Porter-Cologne Act, adding chapter 5.5 (Wat. Code, 

§ 13370 et seq.) to authorize state issuance of permits (Wat. Code, § 13370, subd. 

(c)). The Legislature explained the amendment was ―in the interest of the people 

of the state, in order to avoid direct regulation by the federal government of 

persons already subject to regulation under state law pursuant to [the PorterCologne Act].‖ (Ibid.) The Legislature provided that Chapter 5.5 be ―construed to 

ensure consistency‖ with the CWA. (Wat. Code, § 13372, subd. (a).) It directed 

that state and regional boards issue waste discharge requirements ―ensur[ing] 

compliance with all applicable provisions of the [CWA] . . . together with any 

more stringent effluent standards or limitations necessary to implement water 

quality control plans, or for the protection of beneficial uses, or to prevent 

nuisance.‖ (Wat. Code, § 13377, italics added.) To align the state and federal 

 

3 For a state to acquire permitting authority, the governor must give the EPA 

a ―description of the program [the state] proposes to establish,‖ and the attorney 

general must affirm that the laws of the state ―provide adequate authority to carry 

out the described program.‖ (33 U.S.C. § 1342(b).) 

4 The EPA may withdraw approval of a state‘s program (33 

U.S.C. § 1342(c)(3)), and also retains some supervisory authority: States must 

inform the EPA of all permit applications received and of any action related to the 

consideration of a submitted application (33 U.S.C. § 1342(d)(1)).
6

permitting systems, the legislation provided that the term ―  ̳waste discharge

requirements‘ ‖ under the Act was equivalent to the term ―  ̳permits‘ ‖ under the 

CWA. (Wat. Code, § 13374.) Accordingly, California‘s permitting system now 

regulates discharges under both state and federal law. (WaterKeepers Northern 

California v. State Water Resources Control Bd. (2002) 102 Cal.App.4th 1448, 

1452; accord Building Industry, supra, 124 Cal.App.4th at p. 875. ) 

In 1987, Congress amended the CWA to clarify that a permit is required for 

any discharge from a municipal storm sewer system serving a population of 

100,000 or more. (33 U.S.C. § 1342(p)(2)(C), (D).) Under those amendments, a 

permit may be issued either on a system- or jurisdiction-wide basis, must 

effectively prohibit non-storm water discharges into the storm sewers, and must 

―require controls to reduce the discharge of pollutants to the maximum extent 

practicable.‖ (33 U.S.C. § 1342(p)(3)(B), italics added.) The phrase ―maximum 

extent practicable‖ is not further defined. How that phrase is applied, and by 

whom, are important aspects of this case. 

EPA regulations specify the information to be included in a permit 

application. (See 40 C.F.R. § 122.26(d)(1)(i)-(vi), (d)(2)(i)-(viii).) Among other 

things, an applicant must set out a proposed management program that includes 

management practices; control techniques; and system, design, and engineering 

methods to reduce the discharge of pollutants to the maximum extent practicable. 

(40 C.F.R. § 122.26(d)(2)(iv).) The permit-issuing agency has discretion to 

determine which practices, whether or not proposed by the applicant, will be 

imposed as conditions. (Ibid.) 

B. The Permit in Question

In 2001, Los Angeles County (the County), acting for all Operators, applied 

for a permit from the Regional Board. The board issued a permit (the Permit), 
7

with conditions intended to ―reduce the discharge of pollutants in storm water to 

the Maximum Extent Practicable‖ in the Operators‘ jurisdiction. The Permit 

stated that its conditions implemented both the Porter-Cologne Act and the CWA. 

Part 4 of the Permit contains the four requirements at issue. Part 4(C) 

addresses commercial and industrial facilities, and required the Operators to 

inspect certain facilities twice during the five-year term of the Permit. Inspection 

requirements were set out in substantial detail.

5 Part 4(E) of the Permit addresses

construction sites. It required each Operator to ―implement a program to control 

runoff from construction activity at all construction sites within its jurisdiction,‖ 

and to inspect each construction site of one acre or greater at least ―once during 

the wet season.‖6 Finally, Part 4(F) of the Permit addresses pollution from public 

agency activities. Among other things, it directed each Operator not otherwise 

regulated to ―[p]lace trash receptacles at all transit stops within its jurisdiction,‖ 

and to maintain them as necessary. 

 

5 As to commercial facilities, Part 4(C)(2)(a) required each Operator to 

inspect each restaurant, automotive service facility, retail gasoline outlet, and 

automotive dealership within its jurisdiction, and to confirm that the facility 

employed best management practices in compliance with state law, county and 

municipal ordinances, a Regional Board resolution, and the Operators‘ storm 

water quality management program (SQMP). For each type of facility, the Permit 

set forth specific inspection tasks.

Part 4(C)(2)(b) addressed industrial facilities, requiring the Operators to 

inspect them and confirm that each complied with county and municipal 

ordinances, a Regional Board resolution, and the SQMP. The Operators also were 

required to inspect industrial facilities for violations of the general industrial 

activity stormwater permit, a statewide permit issued by the State Board that 

regulates discharges from industrial facilities. (See discussion, post, at pp. 24-25.) 

6 Part 4(E)(4) required inspections for violations of the general construction 

activity stormwater permit, another statewide permit issued by the State Board. 

(See discussion, post, at pp. 24-25.)

C. Local Agency Claims

1. Applicable procedures for seeking reimbursement

As mentioned, when the Legislature or a state agency requires a local 

government to provide a new program or higher level of service, the state must 

―reimburse that local government for the costs of the program or increased level of 

service.‖ (Cal. Const., art. XIII B, § 6, subd. (a) (hereafter, section 6).)7 

However, reimbursement is not required if ―[t]he statute or executive order 

imposes a requirement that is mandated by a federal law or regulation and results 

in costs mandated by the federal government, unless the statute or executive order 

mandates costs that exceed the mandate in that federal law or regulation.‖ (Gov. 

Code, § 17556, subd. (c).) 

The Legislature has enacted comprehensive procedures for the resolution of 

reimbursement claims (Gov. Code, § 17500 et seq.) and created the Commission 

to adjudicate them. (Gov. Code, §§ 17525, 17551.) It also established ―a testclaim procedure to expeditiously resolve disputes affecting multiple agencies.‖ 

(Kinlaw v. State of California (1991) 54 Cal.3d 326, 331 (Kinlaw).) 

The first reimbursement claim filed with the Commission is called a test 

claim. (Gov. Code, § 17521.) The Commission must hold a public hearing, at 

which the Department of Finance (the Department), the claimant, and any other 

affected department or agency may present evidence. (Gov. Code, §§ 17551, 

17553.) The Commission then determines ―whether a state mandate exists and, if 

 

7 ―  ̳Costs mandated by the state‘ means any increased costs which a local 

agency or school district is required to incur . . . as a result of any statute enacted 

on or after January 1, 1975, or any executive order implementing any statute 

enacted on or after January 1, 1975, which mandates a new program or higher 

level of service of an existing program within the meaning of Section 6 of Article 

XIIIB of the California Constitution.‖ (Gov. Code, § 17514.) 
9

so, the amount to be reimbursed.‖ (Kinlaw, supra, 54 Cal.3d at p. 332.) The 

Commission‘s decision is reviewable by writ of mandate. (Gov. Code, § 17559.) 

2. The test claims

The County and other Operators filed test claims with the Commission, 

seeking reimbursement for the Permit‘s inspection and trash receptacle 

requirements. The Department, State Board, and Regional Board (collectively, the 

State) responded that the Operators were not entitled to reimbursement because 

each requirement was federally mandated. 

The Department argued that the EPA had delegated its federal permitting 

authority to the Regional Board, which acted as an administrator for the EPA, 

ensuring the state‘s program complied with the CWA. The Department 

acknowledged the Regional Board had discretion to set detailed permit conditions,

but urged that the challenged conditions were required for the Permit to comply 

with federal law. 

The State and Regional Boards argued somewhat differently. They 

contended the CWA required the Regional Board to impose specific permit 

controls to reduce the discharge of pollutants to the ―maximum extent 

practicable.‖ Thus, when the Regional Board determined the Permit‘s conditions, 

those conditions were part of the federal mandate. The State and Regional Boards 

also argued that the challenged conditions were ―animated‖ by EPA regulations. 

In support of the trash receptacle requirement, they relied on 40 Code of Federal 

Regulations part 122.26(d)(2)(iv)(A)(3).

8 In support of the inspection 

 

8 40 Code of Federal Regulations part 122.26(d)(2)(iv)(A) provides that the 

proposed management plan in an operator‘s permit application must be based, in 

part, on a ―description of structural and source control measures to reduce 

pollutants from runoff from commercial and residential areas that are discharged 

from the municipal storm sewer system that are to be implemented during the life 

(footnote continued on next page)
10

requirements, they relied on 40 Code of Federal Regulations part 

122.26(d)(2)(iv)(B)(1),

9 (C)(1),10 and (D)(3).11 

 

(footnote continued from previous page)

of the permit, accompanied with an estimate of the expected reduction of pollutant 

loads and a proposed schedule for implementing such controls,‖ and that, at a 

minimum, that description shall include, among other things, a ―description of 

practices for operating and maintaining public streets, roads and highways and 

procedures for reducing the impact on receiving waters of discharges from 

municipal storm sewer systems, including pollutants discharged as a result of 

deicing activities.‖ (40 C.F.R. § 122.26(d)(2)(iv)(A), (A)(3).) 

9 40 Code of Federal Regulations part 122.26(d)(2)(iv)(B) provides that the 

proposed management plan in an operator‘s permit application must be based, in 

part, on a ―description of a program, including a schedule, to detect and remove . . 

. illicit discharges and improper disposal into the storm sewer,‖ and that the 

proposed program shall include a ―description of a program, including inspections, 

to implement and enforce an ordinance, orders or similar means to prevent illicit 

discharges to the municipal separate storm sewer system.‖ (40 C.F.R. 

§ 122.26(d)(2)(iv)(B), (B)(1).) 

10 40 Code of Federal Regulations part 122.26(d)(2)(iv)(C) provides that the 

proposed management plan in an operator‘s permit application must be based, in 

part, on a ―description of a program to monitor and control pollutants in storm 

water discharges to municipal systems from municipal landfills, hazardous waste 

treatment, disposal and recovery facilities, industrial facilities that are subject to 

section 313 of title III of the Superfund Amendments and Reauthorization Act of 

1986 (SARA), and industrial facilities that the municipal permit applicant 

determines are contributing a substantial pollutant loading to the municipal storm 

sewer system,‖ and that the program shall ―[i]dentify priorities and procedures for 

inspections and establishing and implementing control measures for such 

discharges.‖ (40 C.F.R. § 122.26(d)(2)(iv)(C), (C)(1).) 

11 40 Code of Federal Regulations part 122.26(d)(2)(iv)(D) provides that the 

proposed management plan in an operator‘s permit application must be based, in 

part, on a ―description of a program to implement and maintain structural and nonstructural best management practices to reduce pollutants in storm water runoff 

from construction sites to the municipal storm sewer system,‖ which shall include, 

a ―description of procedures for identifying priorities for inspecting sites and 

enforcing control measures which consider the nature of the construction activity, 

(footnote continued on next page)
11

The Operators argued the conditions were not mandated by federal law, 

because nothing in the CWA or in the cited federal regulations required them to 

install trash receptacles or perform the required site inspections. They also

submitted evidence showing that none of the challenged requirements were 

contained in their previous permits issued by the Regional Board, nor were they 

imposed on other municipal storm sewer systems by the EPA. 

As to the inspection requirements, the Operators argued that state law 

required the state and regional boards to regulate discharges of waste. This 

regulatory authority included the power to inspect facilities and sites. The 

Regional Board had used the Permit conditions to shift those inspection 

responsibilities to them. They also presented evidence that the Regional Board 

was required to inspect industrial facilities and construction sites for compliance 

with statewide permits issued by the State Board (see ante, p. 7, fns. 5, 6). They 

urged that the Regional Board had shifted that obligation to the Operators as well. 

Finally, the Operators submitted a declaration from a county employee indicating 

the Regional Board had offered to pay the County to inspect industrial facilities on 

behalf of the Regional Board, but revoked that offer after including the inspection 

requirement in the Permit. 

The EPA submitted comments to the Commission indicating that the 

challenged permit requirements were designed to reduce the discharge of 

pollutants to the ―maximum extent practicable.‖ Thus, the EPA urged the 

requirements fell ―within the scope‖ of federal regulations and other EPA 

 

(footnote continued from previous page)

topography, and the characteristics of soils and receiving water quality.‖ (40 

C.F.R. § 122.26(d)(2)(iv)(D), (D)(3).)
12

guidance regarding storm water management programs. The Bay Area 

Stormwater Management Agencies Association, the League of California Cities, 

and the California State Association of Counties submitted comments urging that 

the challenged requirements were state, rather than federal, mandates. 

3. The commission’s decision

By a four-to-two vote, the Commission partially approved the test claims, 

concluding none of the challenged requirements were mandated by federal law. 

However, the Commission determined the Operators were not entitled to 

reimbursement for the inspection requirements because they had authority to levy

fees to pay for the required inspections. Under Government Code section 17556, 

subdivision (d), the constitutional reimbursement requirement does not apply if the 

local government has the authority to levy fees or assessments sufficient to pay for 

the mandated program or service. 

4. Petitions for writ of mandate

The State challenged the Commission‘s determination that the requirements 

were state mandates. By cross-petition, the County and certain cities challenged 

the Commission‘s finding that they could impose fees to pay for the inspections. 

The trial court concluded that, because each requirement fell ―within the 

maximum extent practicable standard,‖ they were federal mandates not subject to 

reimbursement. It granted the State‘s petition and ordered the Commission to 

issue a new statement of decision. The court did not reach the cross-claims 

relating to fee authority. Certain Operators appealed.12 The Court of Appeal 

 

12 The appellants are County and the Cities of Artesia, Azusa, Bellflower, 

Beverly Hills, Carson, Commerce, Covina, Downey, Monterey Park, Norwalk, 

Rancho Palo Verdes, Signal Hill, Vernon, and Westlake Village. 
13

affirmed, concluding as a matter of law that the trash receptacle and inspection 

requirements were federal mandates. 

II. DISCUSSION

A. Standard of Review

Courts review a decision of the Commission to determine whether it is 

supported by substantial evidence. (Gov. Code, § 17559.) Ordinarily, when the 

scope of review in the trial court is whether the administrative decision is 

supported by substantial evidence, the scope of review on appeal is the same. 

(County of Los Angeles v. Commission on State Mandates (1995) 32 Cal.App.4th 

805, 814 (County of Los Angeles).) However, the appellate court independently 

reviews conclusions as to the meaning and effect of constitutional and statutory 

provisions. (City of San Jose v. State of California (1996) 45 Cal.App.4th 1802, 

1810.) The question whether a statute or executive order imposes a mandate is a 

question of law. (Ibid.) Thus, we review the entire record before the Commission, 

which includes references to federal and state statutes and regulations, as well as 

evidence of other permits and the parties‘ obligations under those permits, and 

independently determine whether it supports the Commission‘s conclusion that the 

conditions here were not federal mandates. (Ibid.) 

B. Analysis

The parties do not dispute here that each challenged requirement is a new 

program or higher level of service. The question here is whether the requirements 

were mandated by a federal law or regulation.

1. The federal mandate exception

Voters added article XIII B to the California Constitution in 1979. Also 

known as the ―Gann limit,‖ it ―restricts the amounts state and local governments

may appropriate and spend each year from the  ̳proceeds of taxes.‘ ‖ (City of 
14

Sacramento v. State of California (1990) 50 Cal.3d 51, 58-59 (City of 

Sacramento).) ―Article XIII B is to be distinguished from article XIII A, which 

was adopted as Proposition 13 at the June 1978 election. Article XIII A imposes a 

direct constitutional limit on state and local power to adopt and levy taxes. 

Articles XIII A and XIII B work in tandem, together restricting California 

governments‘ power both to levy and to spend for public purposes.‖ (Id. at p. 59, 

fn. 1.)

The ―concern which prompted the inclusion of section 6 in article XIII B 

was the perceived attempt by the state to enact legislation or adopt administrative 

orders creating programs to be administered by local agencies, thereby transferring 

to those agencies the fiscal responsibility for providing services which the state 

believed should be extended to the public.‖ (County of Los Angeles v. State of 

California (1987) 43 Cal.3d 46, 56.) The reimbursement provision in section 6 

was included in recognition of the fact ―that articles XIII A and XIII B severely 

restrict the taxing and spending powers of local governments.‖ (County of San 

Diego v. State of California (1997) 15 Cal.4th 68, 81 (County of San Diego).) The 

purpose of section 6 is to prevent ―the state from shifting financial responsibility 

for carrying out governmental functions to local agencies, which are  ̳ill equipped‘ 

to assume increased financial responsibilities because of the taxing and spending 

limitations that articles XIII A and XIII B impose.‖ (County of San Diego, at p. 

81.) Thus, with certain exceptions, section 6 ―requires the state  ̳to pay for any 

new governmental programs, or for higher levels of service under existing 

programs, that it imposes upon local governmental agencies.‘ ‖ (County of San 

Diego, at p. 81.)

As noted, reimbursement is not required if the statute or executive order 

imposes ―a requirement that is mandated by a federal law or regulation,‖ unless 

the state mandate imposes costs that exceed the federal mandate. (Gov. Code, 
15

§ 17556, subd. (c).) The question here is how to apply that exception when federal 

law requires a local agency to obtain a permit, authorizes the state to issue the 

permit, and provides the state discretion in determining which conditions are 

necessary to achieve a general standard established by federal law, and when state 

law allows the imposition of conditions that exceed the federal standard. Previous 

decisions of this court and the Courts of Appeal provide guidance. 

In City of Sacramento, supra, 50 Cal.3d 51, this court addressed local 

governments‘ reimbursement claims for the costs of extending unemployment 

insurance protection to their employees. (Id., at p. 59.) Since 1935, the applicable 

federal law had provided powerful incentives for states to implement their own 

unemployment insurance programs. Those incentives included federal subsidies 

and a substantial federal tax credit for all corporations in states with certified 

federal programs. (Id. at p. 58.) California had implemented such a program. 

(Ibid.) In 1976, Congressional legislation required that unemployment insurance 

protection be extended to local government employees. (Ibid.) If a state failed to 

comply with that directive, it ―faced [the] loss of the federal tax credit and 

administrative subsidy.‖ (Ibid.) The Legislature passed a law requiring local 

governments to participate in the state‘s unemployment insurance program. (Ibid.) 

Two local governments sought reimbursement for the costs of complying 

with that requirement. Opposing the claims, the state argued its action was 

compelled by federal law. This court agreed, reasoning that, if the state had 

―failed to conform its plan to new federal requirements as they arose, its 

businesses [would have] faced a new and serious penalty‖ of double taxation, 

which would have placed those businesses at a competitive disadvantage against 

businesses in states complying with federal law. (City of Sacramento, supra, 50 

Cal.3d at p. 74.) Under those circumstances, we concluded that the ―state simply 

did what was necessary to avoid certain and severe federal penalties upon its 
16

resident businesses.‖ (Ibid.) Because ―[t]he alternatives were so far beyond the 

realm of practical reality that they left the state  ̳without discretion‘ to depart from 

federal standards,‖ we concluded ―the state acted in response to a federal 

 ̳mandate.‘ ‖ (Ibid., italics added.) 

County of Los Angeles, supra, 32 Cal.App.4th 805, involved a different 

kind of federal compulsion. In Gideon v. Wainwright (1963) 372 U.S. 335, the 

United States Supreme Court held that states were required by the federal 

Constitution to provide counsel to indigent criminal defendants. That requirement 

had been construed to include ―the right to the use of any experts that will assist 

counsel in preparing a defense.‖ (County of Los Angeles, at p. 814.) The 

Legislature enacted Penal Code section 987.9, requiring local governments to 

provide indigent criminal defendants with experts for the preparation of their 

defense. (County of Los Angeles, at p. 811, fn. 3.) Los Angeles County sought 

reimbursement for the costs of complying with the statute. The state argued the 

statute‘s requirements were mandated by federal law. 

The state prevailed. The Court of Appeal reasoned that, even without Penal 

Code section 987.9, the county would have been ―responsible for providing 

ancillary services‖ under binding Supreme Court precedent. (County of Los 

Angeles, supra, 32 Cal.App.4th at p. 815.) Penal Code section 987.9 merely 

codified an existing federal mandate. (County of Los Angeles, at p. 815.) 

Hayes v. Commission on State Mandates (1992) 11 Cal.App.4th 1564 

(Hayes) provides a contrary example. Hayes involved the federal Education of the 

Handicapped Act (EHA; 20 U.S.C. § 1401 et seq.). EHA was a ―comprehensive 

measure designed to provide all handicapped children with basic educational 

opportunities.‖ (Hayes, at p. 1594.) EHA required each state to adopt an 

implementation plan, and mandated ―certain substantive and procedural 
17

requirements,‖ but left ―primary responsibility for implementation to the state.‖ 

(Hayes, at p. 1594.)

Two local governments sought reimbursement for the costs of special 

education assessment hearings which were required under the state‘s adopted plan. 

The state argued the requirements imposed under its plan were federally 

mandated. The Hayes court rejected that argument. Reviewing the historical 

development of special education law (Hayes, supra, 11 Cal.App.4th at pp. 1582-

1592), the court concluded that, so far as the state was concerned, the requirements 

established by the EHA were federally mandated. (Hayes, at p. 1592.) However, 

that conclusion ―mark[ed] the starting point rather than the end of [its] 

consideration.‖ (Ibid.) The court explained that, in determining whether federal 

law requires a specified function, like the assessment hearings, the focus of the 

inquiry is whether the ―manner of implementation of the federal program was left 

to the true discretion of the state.‖ (Id. at p. 1593, italics added.) If the state ―has 

adopted an implementing statute or regulation pursuant to the federal mandate,‖

and had ―no  ̳true choice‘ ‖ as to the manner of implementation, the local 

government is not entitled to reimbursement. (Ibid.) If, on the other hand, ―the 

manner of implementation of the federal program was left to the true discretion of 

the state,‖ the local government might be entitled to reimbursement. (Ibid.) 

According to the Hayes court, the essential question is how the costs came 

to be imposed upon the agency required to bear them. ―If the state freely chose to 

impose the costs upon the local agency as a means of implementing a federal 

program then the costs are the result of a reimbursable state mandate regardless 

whether the costs were imposed upon the state by the federal government.‖ 

(Hayes, supra, 11 Cal.App.4th at p. 1594.) Applying those principles, the court 

concluded that, to the extent ―the state implemented the [EHA] by freely choosing 

to impose new programs or higher levels of service upon local school districts, the 
18

costs of such programs or higher levels of service are state mandated and subject 

to‖ reimbursement. (Ibid.)

From City of Sacramento, County of Los Angeles, and Hayes, we distill the 

following principle: If federal law compels the state to impose, or itself imposes, a 

requirement, that requirement is a federal mandate. On the other hand, if federal 

law gives the state discretion whether to impose a particular implementing 

requirement, and the state exercises its discretion to impose the requirement by 

virtue of a ―true choice,‖ the requirement is not federally mandated. 

Division of Occupational Safety & Health v. State Bd. of Control (1987) 

189 Cal.App.3d 794 (Division of Occupational Safety) is instructive. The federal 

Occupational Safety and Health Act (Fed. OSHA; 29 U.S.C. § 651 et seq.) 

preempted states from regulating matters covered by Fed. OSHA unless a state 

had adopted its own plan and gained federal approval. (Division of Occupational 

Safety, at p. 803.) No state was obligated to adopt its own plan. But, if a state did 

so, the plan had to include standards at least as effective as Fed. OSHA‘s and 

extend those standards to state and local employees. California adopted its own 

plan, which was federally approved. The state then issued a regulation that, 

according to local fire districts, required them to maintain three-person firefighting 

teams. Previously, they had been permitted to maintain two-person teams. 

(Division of Occupational Safety, at pp. 798-799.) The local fire districts sought 

reimbursement for the increased level of service. The state opposed, arguing the 

requirement was mandated by federal law. 

The court agreed with the fire districts. As the court explained, a Fed. 

OSHA regulation arguably required the maintenance of three-person firefighting 

teams. (Division of Occupational Safety, supra, 189 Cal.App.3d at p. 802.) 

However, that federal regulation specifically excluded local fire districts. (Id. at p. 

803.) Had the state elected to be governed by Fed. OSHA standards, that 
19

exclusion would have allowed those fire districts to maintain two-person teams. 

(Division of Occupational Safety, at p. 803.) The conditions for approval of the 

state’s plan required effective enforcement and coverage of public employees. 

But those conditions did not make the costs of complying with the state regulation 

federally mandated. ―[T]he decision to establish . . . a federally approved [local] 

plan is an option which the state exercises freely.‖ (Ibid.) In other words, the 

state was not ―compelled to . . . extend jurisdiction over occupational safety to 

local governmental employers,‖ which would have otherwise fallen under a 

federal exclusion. (Ibid.) Because the state ―was not required to promulgate [the 

state regulation] to comply with federal law, the exemption for federally mandated 

costs does not apply.‖ (Id. at p. 804.)13 

San Diego Unified School Dist. v. Commission on State Mandates (2004) 

33 Cal.4th 859 (San Diego Unified) provides another example. In Goss v. Lopez

(1975) 419 U.S. 565, the United States Supreme Court held that if a school 

principal chose to recommend a student for expulsion, federal due process 

principles required the school district to give that student a hearing. Education 

Code section 48918 provided for expulsion hearings. (San Diego Unified, at p. 

868.) Under Education Code section 48915, a school principal had discretion to 

recommend expulsion under certain circumstances, but was compelled to 

recommend expulsion for a student who possessed a firearm. (San Diego Unified, 

at p. 869.) Federal law at the time did not require expulsion for a student who 

brought a gun to school. (Id. at p. 883.) 

 

13 In the end, the court held that the challenged state regulation did not 

obligate the local fire district to maintain three-person firefighting teams. 

Accordingly, the state regulation did not mandate an increase in costs. (Division 

of Occupational Safety, supra, 189 Cal.App.3d at pp. 807-808.) 
20

The school district argued it was entitled to reimbursement of all expulsion 

hearing costs. This court drew a distinction between discretionary and mandatory 

expulsions. We concluded the costs of hearings for discretionary expulsions

flowed from a federal mandate. (San Diego Unified, supra, 33 Cal.4th at pp. 884-

890.)14 We declined, however, to extend that rule to the costs related to 

mandatory expulsions. Because it was state law that required an expulsion 

recommendation for firearm possession, all hearing costs triggered by the 

mandatory expulsion provision were reimbursable state-mandated expenses. (Id. 

at pp. 881-883). As was the case in Hayes, the key factor was how the costs came 

to be imposed on the entity that was required to bear them. The school principal 

could avoid the cost of a federally-mandated hearing by choosing not to 

recommend an expulsion. But, when a state statute required an expulsion 

recommendation, the attendant hearing costs did not flow from a federal mandate. 

(San Diego Unified, supra, 33 Cal.4th at p. 881.) 

2. Application

Review of the Commission‘s decision requires a determination as to 

whether federal statutory, administrative, or case law imposed, or compelled the 

Regional Board to impose, the challenged requirements on the Operators. 

It is clear federal law did not compel the Regional Board to impose these 

particular requirements. There was no evidence the state was compelled to 

administer its own permitting system rather than allowing the EPA do so under the 

CWA. (33 U.S.C. § 1342(a).) In this respect, the case is similar to Division of 

 

14 To the extent Education Code section 48918 imposed requirements that 

went beyond the mandate of federal law, those requirements were merely 

incidental to the federal mandate, and at most resulted in ―a de minimis cost.‖ 

(San Diego Unified, supra, 33 Cal.4th at p. 890.) The State does not argue here 

that the costs of the challenged permit conditions were de minimis. 
21

Occupational Safety, supra, 189 Cal.App.3d 794. Here, as in that case, the state 

chose to administer its own program, finding it was ―in the interest of the people 

of the state, in order to avoid direct regulation by the federal government of 

persons already subject to regulation‖ under state law. (Wat. Code, § 13370, subd. 

(c), italics added.) Moreover, the Regional Board was not required by federal law 

to impose any specific permit conditions. The federal CWA broadly directed the 

board to issue permits with conditions designed to reduce pollutant discharges to 

the maximum extent practicable. But the EPA‘s regulations gave the board 

discretion to determine which specific controls were necessary to meet that 

standard. (40 C.F.R. § 122.26(d)(2)(iv).) This case is distinguishable from City of 

Sacramento, supra, 50 Cal.3d 51, where the state risked the loss of subsidies and 

tax credits for all its resident businesses if it failed to comply with federal 

legislation. Here, the State was not compelled by federal law to impose any 

particular requirement. Instead, as in Hayes, supra, 11 Cal.App.4th 1564, the 

Regional Board had discretion to fashion requirements which it determined would 

meet the CWA‘s maximum extent practicable standard. 

The State argues the Commission failed to account for the flexibility in the 

CWA‘s regulatory scheme, which conferred discretion on the State and regional 

boards in deciding what conditions were necessary to comply with the CWA. In 

exercising that discretion, those agencies were required to rely on their scientific, 

technical, and experiential knowledge. Thus, the State contends the Permit itself 

is the best indication of what requirements would have been imposed by the EPA 

if the Regional Board had not done so, and the Commission should have deferred 

to the board‘s determination of what conditions federal law required.

We disagree that the Permit itself demonstrates what conditions would have 

been imposed had the EPA granted the Permit. In issuing the Permit, the Regional 

Board was implementing both state and federal law and was authorized to include 
22

conditions more exacting than federal law required. (City of Burbank, supra, 35 

Cal.4th at pp. 627-628.) It is simply not the case that, because a condition was in 

the Permit, it was, ipso facto, required by federal law. 

We also disagree that the Commission should have deferred to the Regional 

Board‘s conclusion that the challenged requirements were federally mandated. 

That determination is largely a question of law. Had the Regional Board found, 

when imposing the disputed permit conditions, that those conditions were the only 

means by which the maximum extent practicable standard could be implemented, 

deference to the board‘s expertise in reaching that finding would be appropriate. 

The board‘s legal authority to administer the CWA and its technical experience in 

water quality control would call on sister agencies as well as courts to defer to that 

finding. The State, however, provides no authority for the proposition that, absent 

such a finding, the Commission should defer to a state agency as to whether 

requirements were state or federally mandated. Certainly, in a trial court action 

challenging the board’s authority to impose specific permit conditions, the board‘s

findings regarding what conditions satisfied the federal standard would be entitled 

to deference. (See, e.g., City of Rancho Cucamonga v. Regional Water Quality 

Control Bd. (2006) 135 Cal.App.4th 1377, 1384, citing Fukuda v. City of Angels

(1999) 20 Cal.4th 805, 817-818.) Resolution of those questions would bring into 

play the particular technical expertise possessed by members of the regional board. 

In those circumstances, the party challenging the board‘s decision would have the 

burden of demonstrating its findings were not supported by substantial evidence or 

that the board otherwise abused its discretion. (Rancho Cucamonga, at p. 1387; 

Building Industry, supra, 124 Cal.App.4th at pp. 888-889.) 

Reimbursement proceedings before the Commission are different. The 

question here was not whether the Regional Board had authority to impose the 

challenged requirements. It did. The narrow question here was who will pay for 
23

them. In answering that legal question, the Commission applied California‘s 

constitutional, statutory, and common law to the single issue of reimbursement. In 

the context of these proceedings, the State has the burden to show the challenged 

conditions were mandated by federal law. 

Section 6 establishes a general rule requiring reimbursement of all statemandated costs. Government Code section 17556, subdivision (c), codifies an 

exception to that rule. Typically, the party claiming the applicability of an 

exception bears the burden of demonstrating that it applies. (See Simpson StrongTie Co., Inc. v. Gore (2010) 49 Cal.4th 12, 23; see also, Long Beach Police 

Officers Assn. v. City of Long Beach (2014) 59 Cal.4th 59, 67.) Here, the State 

must explain why federal law mandated these requirements, rather than forcing the 

Operators to prove the opposite. The State‘s proposed rule, requiring the 

Commission to defer to the Regional Board, would leave the Commission with no 

role to play on the narrow question of who must pay. Such a result would fail to 

honor the Legislature‘s intent in creating the Commission.

Moreover, the policies supporting article XIII B of the California 

Constitution and section 6 would be undermined if the Commission were required 

to defer to the Regional Board on the federal mandate question. The central 

purpose of article XIII B is to rein in local government spending. (City of 

Sacramento, supra, 50 Cal.3d at pp. 58-59.) The purpose of section 6 is to protect 

local governments from state attempts to impose or shift the costs of new 

programs or increased levels of service by entitling local governments to 

reimbursement. (County of San Diego, supra, 15 Cal.4th at p. 81.) Placing the 

burden on the state to demonstrate that a requirement is federally mandated, and 

thus excepted from reimbursement, serves those purposes. 

Applying the standard of review described above, we evaluate the entire 

record and independently review the Commission‘s determination the challenged 
24

conditions were not federal mandates. We conclude the Commission was correct. 

These permit conditions were not federally mandated.

a) The inspection requirements

Neither the CWA‘s ―maximum extent practicable‖ provision nor the EPA 

regulations on which the State relies expressly required the Operators to inspect 

these particular facilities or construction sites. The CWA makes no mention of 

inspections. (33 U.S.C. § 1342(p)(3)(B)(iii).) The regulations required the 

Operators to include in their permit application a description of priorities and 

procedures for inspecting certain industrial facilities and construction sites, but 

suggested that the Operators would have discretion in selecting which facilities to 

inspect. (See C.F.R. § 122.26(d)(2)(iv)(C)(1).) The regulations do not mention 

commercial facility inspections at all. 

Further, as the Operators explained, state law made the Regional Board

responsible for regulating discharges of waste within its jurisdiction. (Wat. Code,

§§ 13260, 13263.) This regulatory authority included the power to ―inspect the 

facilities of any person to ascertain whether . . . waste discharge requirements are 

being complied with.‖ (Wat. Code, § 13267, subd. (c).) Thus, state law imposed 

an overarching mandate that the Regional Board inspect the facilities and sites. 

In addition, federal law and practice required the Regional Board to inspect 

all industrial facilities and construction sites. Under the CWA, the State Board, as 

an issuer of NPDES permits, was required to issue permits for storm water 

discharges ―associated with industrial activity.‖ (33 U.S.C. § 1342(p)(3)(A).) The 

term ―industrial activity‖ includes ―construction activity.‖ (40 C.F.R. 

§ 122.26(b)(14)(x).) The Operators submitted evidence that the State Board had 

satisfied its obligation by issuing a general industrial activity stormwater permit 

and a general construction activity stormwater permit. Those statewide permits
25

imposed controls designed to reduce pollutant discharges from industrial facilities 

and construction sites. Under the CWA, those facilities and sites could operate 

under the statewide permits rather than obtaining site-specific pollutant discharge 

permits.

The Operators showed that, in those statewide permits, the State Board had 

placed responsibility for inspecting facilities and sites on the Regional Board. The 

Operators submitted letters from the EPA indicating the State and regional boards

were responsible for enforcing the terms of the statewide permits. The Operators

also noted the State Board was authorized to charge a fee to facilities and sites that 

subscribed to the statewide permits (Wat. Code, § 13260, subd. (d)), and that a 

portion of that fee was earmarked to pay the Regional Board for ―inspection and 

regulatory compliance issues.‖ (Wat. Code, § 13260, subd. (d)(2)(B)(iii).) 

Finally, there was evidence the Regional Board offered to pay the County to 

inspect industrial facilities. There would have been little reason to make that offer 

if federal law required the County to inspect those facilities.

This record demonstrates that the Regional Board had primary 

responsibility for inspecting these facilities and sites. It shifted that responsibility 

to the Operators by imposing these Permit conditions. The reasoning of Hayes, 

supra, 11 Cal.App.4th 1564, provides guidance. There, the EHA required the state 

to provide certain services to special education students, but gave the state 

discretion in implementing the federal law. (Hayes, at p. 1594.) The state 

exercised its ―true discretion‖ by selecting the specific requirements it imposed on 

local governments. As a result, the Hayes court held the costs incurred by the 

local governments were state-mandated costs. (Ibid.) Here, state and federal law 

required the Regional Board to conduct inspections. The Regional Board

exercised its discretion under the CWA, and shifted that obligation to the 

Operators. That the Regional Board did so while exercising its permitting 
26

authority under the CWA does not change the nature of the Regional Board‘s 

action under section 6. Under the reasoning of Hayes, the inspection requirements 

were not federal mandates. 

The State argues the inspection requirements were federally mandated 

because the CWA required the Regional Board to impose permit controls, and the 

EPA regulations contemplated that some kind of operator inspections would be 

required. That the EPA regulations contemplated some form of inspections, 

however, does not mean that federal law required the scope and detail of 

inspections required by the Permit conditions.15 As explained, the evidence 

before the Commission showed the opposite to be true. 

b) The trash receptacle requirement

The Commission concluded the trash receptacle requirement was not a 

federal mandate because neither the CWA nor the regulation cited by the State 

explicitly required the installation and maintenance of trash receptacles. The State 

contends the requirement was mandated by the CWA and by the EPA regulation 

that directed the Operators to include in their application a ―description of 

practices for operating and maintaining public streets, roads and highways and 

procedures for reducing the impact on receiving waters of discharges from 

municipal storm sewer systems.‖ (40 C.F.R. § 122.26(d)(2)(iv)(A)(3).) 

The Commission‘s determination was supported by the record. While the 

Operators were required to include a description of practices and procedures in 

 

15 The State also relied on a 2008 letter from the EPA indicating that the 

requirements to inspect industrial facilities and construction sites fell within the 

maximum extent practicable standard under the CWA. That letter, however, does 

not indicate that federal law required municipal storm sewer system operators to 

inspect all industrial facilities and construction sites within their jurisdictions.
27

their permit application, the issuing agency has discretion whether to make those 

practices conditions of the permit. (40 C.F.R. § 122.26(d)(2)(iv).) No regulation 

cited by the State required trash receptacles at transit stops. In addition, there was 

evidence that the EPA had issued permits to other municipal storm sewer systems

in Anchorage, Boise, Boston, Albuquerque, and Washington, D.C. that did not 

require trash receptacles at transit stops. The fact the EPA itself had issued 

permits in other cities, but did not include the trash receptacle condition, fatally 

undermines the argument that the requirement was federally mandated.

c) Conclusion

Although we have upheld the Commission‘s determination on the federal 

mandate question, the State raised other arguments in its writ petition. Further, the 

issues presented in the Operators‘ cross-petition were not addressed by either the 

trial court or the Court of Appeal. We remand the matter so those issues can be 

addressed in the first instance.

III. DISPOSITION

We reverse the judgment of the Court of Appeal and remand for further 

proceedings consistent with our opinion.

CHIN, J. 
CONCURRING AND DISSENTING OPINION BY CUÉLLAR, J.

A local government is entitled to reimbursement from the state when the 

Legislature or a state agency requires it to provide new programs or increased 

service. (Cal. Const., art. XIII B, § 6, subd. (a).) But one crucial exception 

coexists with this rule. It applies where the new program or increased service is 

mandated by a federal statute or regulation. (Gov. Code, § 17556, subd. (c).) We 

consider in this case whether certain conditions to protect water quality included in 

a permit from the Regional Water Quality Board, Los Angeles Region (Regional 

Board or Board) — specifically, installation and maintenance of trash receptacles 

at transit stops, as well as inspections of certain commercial and industrial 

facilities and construction sites — constitute state mandates subject to 

reimbursement, or federal mandates within the statutory reimbursement exception.

What the majority concludes is that federal law did not compel imposition 

of the conditions, and that the local agencies would not necessarily have been 

required to comply with them had they not been imposed by the state. In doing so, 

the majority upholds and treats as correct a decision by the Commission on State 

Mandates (the Commission) that is flawed in its approach and far too 

parsimonious in its analysis. This is no small feat: not only must the majority 

discount any expertise the Regional Board might bring to bear on the mandate 

question (see maj. opn., ante, at pp. 22-24), but it must also overlook the 

Commission‘s reliance on an overly narrow analytical framework and prop up the 
2

Commission‘s decision with evidence on which the agency could have relied, 

rather than that on which it did (see id. at pp. 24-27). 

Moreover, when the majority considers whether the permit conditions are 

indeed federally mandated, it purports to apply de novo review to the 

Commission‘s legal determination. (See maj. opn., ante, at pp. 13, 22, 24.) What 

it actually applies seems far more deferential to the Commission‘s decision —

something akin to substantial evidence review — despite the Commission‘s own 

failure in affording deference to the Regional Board and, more generally, its 

reliance on the wrong decision-making framework. (Cf. People v. Barnwell 

(2007) 41 Cal.4th 1038, 1052 [―A substantial evidence inquiry examines the 

record in the light most favorable to the judgment and upholds it if the record 

contains reasonable, credible evidence of solid value upon which a reasonable trier 

of fact could have relied in reaching the conclusion in question‖].) Indeed, what 

the majority overlooks is that the Commission itself should have considered the 

effect of the evidence on which the majority now relies in deciding whether the 

challenged permit conditions were necessary to comply with federal law. And in 

doing so, the Commission should have extended a measure of deference to the 

Regional Board‘s expertise in administering the statutory scheme. (See County of 

Los Angeles v. Cal. State Water Resources Control Bd. (2006) 143 Cal.App.4th 

985, 997 (State Water Board).)

Because the Commission failed to do so, and because the Commission‘s 

interpretation of the federal Clean Water Act (the CWA; 33 U.S.C. § 1251 et seq.) 

failed to account for the complexities of the statute, I would reverse the Court of 

Appeal‘s judgment and remand with instructions for the Commission to reconsider 

its decision. So I concur in the majority‘s judgment reversing the Court of 

Appeal, but dissent from its conclusion upholding the Commission‘s decision 

rather than remanding the matter for further proceedings.
3

I.

To determine whether it is the state rather than local governments that 

should bear the entirety of the financial burden associated with a new program or 

increased service, the Commission must examine the nature of the federal scheme 

in question. That scheme is the CWA, a statute Congress amended in 1972 to 

establish the National Pollutant Discharge Elimination System (the NPDES) as a 

means of achieving and enforcing limitations on pollutant discharges. (See EPA v. 

State Water Resources Control Bd. (1976) 426 U.S. 200, 203-204.) The role 

envisioned for the states under the NPDES is a major one, encompassing both the 

opportunity to assume the primary responsibility for the implementation and 

enforcement of federal effluent discharge limitations by issuing permits as well as 

the discretion to enact requirements that are more onerous than the federal 

standard. (See 33 U.S.C. §§ 1251(b), 1342(b).) 

But states undertaking such implementation must do so in a manner that 

complies with regulations promulgated by the Environmental Protection Agency 

(the EPA), as well as the CWA‘s broad provisions (including the ―maximum 

extent practicable‖ standard (33 U.S.C. § 1342(p)(3)(B)(iii))), and subject to the 

EPA‘s continuing revocation authority (see id., § 1342(c)(3)). Despite the breadth 

of the requirements the statute imposes on states assuming responsibility for 

permitting enforcement and the expansive nature of the EPA‘s revocation 

authority, neither the statute nor its implementing regulations include a safe harbor 

provision establishing a minimum level of compliance with the federal standard —

an absence the majority tacitly acknowledges. (See maj. opn., ante, at p. 21 [―the 

Regional Board was not required by federal law to impose any specific permit 

conditions‖].) Instead, implementation of the federal mandate requires the state 

agency — here, the Regional Board — to exercise technical judgments about the 
4

feasibility of alternative permitting conditions necessary to achieve compliance 

with the federal statute. 

With no statutory safe harbor that the Regional Board could have relied on 

to ensure the EPA‘s approval of the state permitting process, the Board interpreted 

the federal standard in light of the statutory text, implementing regulations, and its 

technical appraisal of potential alternatives. In discharging its own role, the 

Commission was then bound to afford the Regional Board a measure of ―sisteragency‖ deference. (See Yamaha Corp. of America v. State Bd. of Equalization

(1998) 19 Cal.4th 1, 7 [explaining that ―the binding power of an agency‘s

interpretation of a statute or regulation is contextual: Its power to persuade is both 

circumstantial and dependent on the presence or absence of factors that support the 

merit of the interpretation‖].) In this case, the Regional Board informed localities 

that, in its view, the various permit conditions it imposed would satisfy the 

maximum extent practicable standard. The EPA agreed the requirements were 

within the scope of the federal standard. The Regional Board‘s judgment that 

these conditions will control pollutant discharges to the extent required by federal 

law is at the core of the agency‘s institutional expertise. That expertise merits a 

measure of deference because the Regional Board‘s ken includes not only its 

greater familiarity with the CWA (relative to other entities), but also technical 

knowledge relevant to judgments about the water quality consequences of 

particular permitting conditions relevant to the provisions of the CWA. (See, e.g., 

33 U.S.C. § 1342(p)(3)(B)(iii) [requiring that permits include ―management 

practices, control techniques and system, design and engineering methods, and 

such other provisions as . . . the State determines appropriate for the control of 

such pollutants‖].) Casting aside the Regional Board‘s expertise on the issue at 

hand, the majority nonetheless upholds the Commission‘s ruling. 
5

Remand to the Commission would have been the more appropriate course 

for multiple reasons. First, the Commission applied the wrong framework for its 

analysis. It failed to consider all the evidence relevant to whether the permit 

conditions were necessary for compliance with federal law. The commission 

compounded its error by relying on an interpretation of the CWA that 

misconstrues the federal statutory scheme governing the state permitting process.

In particular, the Commission treated the problem as essentially a simple 

matter of searching the statutory text and regulations for precisely the same terms 

used by the Regional Board‘s permit conditions. Unless the requirement in 

question is referenced explicitly in a federal statutory or regulatory provision, the 

Commission‘s analysis suggests, the requirement cannot be a federal mandate. 

With respect to trash receptacles, the Commission stated: ―Because installing and 

maintaining trash receptacles at transit stops is not expressly required of cities or 

counties or municipal separate storm sewer dischargers in the federal statutes or 

regulations, these are activities that  ̳mandate costs that exceed the mandate in the 

federal law or regulation.‘ ‖ And with respect to industrial facility inspections, the 

Commission said this: ―Inasmuch as the federal regulation (40 CFR § 122.26 (c)) 

authorizes coverage under a statewide general permit for the inspections of 

industrial activities, and the federal regulation (40 CFR § 122.26 (d)(2)(iv)(D)) 

does not expressly require those inspections to be performed by the county or 

cities (or the  ̳owner or operator of the discharge‘) the Commission finds that the 

state has freely chosen to impose these activities on the permittees.‖ (Fn. omitted.)

Existing law does not support this method of determining what constitutes a 

federal mandate. Instead, our past decisions emphasize the need to consider the 

implications of multiple statutory provisions and broader statutory context when 

interpreting federal law to determine if a given condition constitutes a federal 

mandate. (See City of Sacramento v. State of California (1990) 50 Cal.3d 51, 76 
6

(City of Sacramento); see also San Diego Unified School Dist. v. Commission on 

State Mandates (2004) 33 Cal.4th 859, 890 [―challenged state rules or procedures 

that are intended to implement an applicable federal law — and whose costs are, 

in context, de minimis — should be treated as part and parcel of the underlying 

federal mandate‖ (italics added)].) In contrast, the Commission‘s overly narrow 

approach to determining what constitutes a federal mandate risks creating a 

standard that will never be met so long as the state retains any shred of discretion 

to implement a federal program. It cannot be that so long as a federal statute or 

regulation does not expressly require every permit term issued by a state agency, 

then the permit is a state, rather than a federal, mandate. But this is precisely how 

the Commission analyzed the issue — an analysis that, remarkably, the majority 

does not even question. Instead, the majority combs the record for evidence that 

could have supported the result the Commission reached. In so doing, the 

majority implicitly acknowledges that the Commission‘s approach to resolving the 

question at the heart of this case was deficient. 

But if the Commission applied the wrong framework for its analysis, the 

right course is to remand. Doing so would obviate the need to cobble together 

scattered support for a decision by the Commission that was premised, in the first 

instance, on the Commission‘s own misconstrual of the inquiry before it. Instead, 

we should give the Commission an opportunity to reevaluate its conclusion in light 

of the entire record and to, where appropriate, solicit further information from the 

parties to shed light on what permit conditions are necessary for compliance with 

federal law. 

The potential consequences of allowing the Commission to continue on its 

present path are quite troubling. For if the law were as the Commission suggests, 

the state would be unduly discouraged from participating in federal programs like 

the NPDES — even though participation might otherwise be in California‘s 
7

interest — if the state knows ex ante that it will be unable to pass along the 

expenses to the local areas that experience the most costs and benefits from the 

mandate at issue. Our law on unfunded mandates does not compel such a result. 

Nor is there an apparent prudential rationale in support of it.

The Commission‘s approach also fails to appreciate the EPA‘s role in 

implementing (through its interpretation and enforcement of the CWA) statutory 

requirements that the CWA describes in relatively broad terms. Indeed, what may 

be ―practicable‖ in Los Angeles may not be in San Francisco, much less in Kansas 

City or Detroit. (See Building Industry Assn. of San Diego County v. State Water 

Resources Control Bd. (2004) 124 Cal.App.4th 866, 889 (Building Industry Assn.) 

[explaining that ―the maximum extent practicable standard is a highly flexible 

concept that depends on balancing numerous factors, including the particular 

control‘s technical feasibility, cost, public acceptance, regulatory compliance, and 

effectiveness‖].) It also suggests a lack of understanding of two interrelated 

matters on which the Regional Board likely has expertise: the consequences of the 

measures included as permit conditions relative to any alternatives and the 

interpretation of a complex federal statute governing regulation of the 

environment.

Second, beyond failing to consider all the relevant evidence bearing on the 

necessity of the imposed permit conditions, the Commission failed to extend any 

meaningful deference to the Regional Board‘s conclusions — even though such 

deference was warranted given that the nature of the decisions involved in 

interpreting the CWA included evaluating appropriate alternatives and 

determining which of those were necessary to satisfy the federal standard. (See 

State Water Board, supra, 143 Cal.App.4th at p. 997 [―we defer to the regional 

board‘s expertise in construing language which is not clearly defined in statutes 

involving pollutant discharge into storm drain sewer systems‖]; City of Rancho 
8

Cucamonga v. Regional Water Quality Control Bd. (2006) 135 Cal.App.4th 1377, 

1384 (Rancho Cucamonga) [―consideration [should be] given to the [regional 

board‘s] interpretations of its own statutes and regulations‖]; Building Industry 

Assn., supra, 124 Cal.App.4th at p. 879, fn. 9 [―we do consider and give due 

deference to the Water Boards‘ statutory interpretations [of the CWA] in this 

case‖]; see also Cal. Building Industry Assn. v. Bay Area Air Quality Management 

Dist. (2015) 62 Cal.4th 369, 389-390 [explaining that ―an agency‘s expertise and 

technical knowledge, especially when it pertains to a complex technical statute, is 

relevant to the court‘s assessment of the value of an agency interpretation‖].) In 

the direct challenge to the permit at issue here, the local agencies argued that the 

Regional Board exceeded even those requirements associated with the maximum 

extent practicable standard, an argument the appellate court rejected in an 

unpublished section of its opinion. Because of its failure to afford any deference 

to the Regional Board or to conduct an analysis more consistent with the relevant 

standard of review, the Commission essentially forces the Board to defend its 

decision twice: once on direct challenge and a second time before the 

Commission. 

Conditions as prosaic as trash receptacle requirements initially may not 

seem to implicate the Regional Board‘s expertise. Yet its unique experience and 

technical competence matter even with respect to these conditions, because the use 

of such conditions implicates a decision not to use alternatives that might require 

greater conventional expert judgment to evaluate. Moreover, the Regional Board 

is likely to accumulate a distinct and greater degree of knowledge regarding issues 

such as the reactions of stakeholders to different requirements, and related factors 

relevant to determining which conditions are necessary to satisfy the CWA‘s 

maximum extent practicable standard.
9

The Commission acknowledged that the State Water Resources Control 

Board — as well as the EPA — believed the permit requirements did not exceed 

this federal standard. ―The comments of the State Water Board and U.S. EPA,‖ 

the Commission noted, ―assert that the permit conditions merely implement a 

federal mandate under the federal Clean Water Act and its regulations.‖ But the 

Commission afforded these conclusions no clear deference in determining whether 

the requirements were state mandates. 

Nor is the majority correct in suggesting that the Commission had only a 

limited responsibility, if it had one at all, to extend any deference to the Regional 

Board. (See maj. opn., ante, at pp. 22-24.) The Regional Board‘s judgment as to 

whether the imposed permit conditions were necessary to comply with federal law 

was a prerequisite to the Commission‘s own task, which was to review the Board‘s 

determination in light of all the relevant evidence. To the extent ambiguity exists 

as to whether the Regional Board‘s conclusions incorporated any findings that 

these conditions were necessary to meet the federal standard (see id. at pp. 22-23), 

remand to clarify the Board‘s position is in order. By instead simply upholding 

the Commission‘s conclusion without remand, the majority displaces any 

meaningful role for the Regional Board‘s expert judgment. 

The majority does so even though courts have routinely emphasized the 

pivotal role regional boards play in interpreting the CWA‘s intricate mandate. 

(See State Water Board, supra, 143 Cal.App.4th at p. 997; Rancho Cucamonga, 

supra, 135 Cal.App.4th at p. 1384.) And for good reason: If the Regional Board‘s 

judgment is that the trash receptacle and inspection requirements are necessary to 

control pollutant discharges to the maximum extent practicable, such a conclusion 

is well within the purview of its expertise. Unsurprisingly, then, we have never 

concluded that the technical knowledge relevant to interpreting the requirements 

of the CWA — a statute that lacks a safe harbor and where discerning what 
10

phrases such as maximum extent practicable mean given existing conditions and 

technology is complex — lies beyond the ambit of the Regional Board‘s expertise, 

or otherwise proves distinct from the sort of expertise that merits deference.

Third, the Commission devoted insufficient attention in its analysis to the 

role of states in implementing the CWA, and to how that role can be harmonized 

with the significant protections against unfunded mandates that the state 

Constitution provides. (See Cal. Const., art. XIII B, § 6, subd. (a).) By allowing 

states to assume such an important role in implementing its provisions, the CWA 

reflects principles of cooperative federalism. (See 33 U.S.C. §§ 1251(b), 1342(b); 

see also Boise Cascade Corp. v. EPA (9th Cir. 1991) 942 F.2d 1427, 1430 [―The 

federal-state relationship established by the [Clean Water] Act is . . . illustrated in 

Congress‘ goal of encouraging states to  ̳assume the major role in the operation of 

the NPDES program‘ ‖].) In accordance with the CWA‘s express provisions, 

California chose to assume the responsibility for implementation of the NPDES 

program in the state — a role that requires further specification of permitting 

conditions. (See 33 U.S.C. § 1342(c)(3) [states must administer permitting 

programs ―in accordance with requirements of this section,‖ including compliance 

with the maximum extent practicable standard].) In the process, the state must 

comply with the constitutional protections against unfunded mandates requiring 

reimbursement of localities if permit conditions exceed what is necessary to 

comply with the relevant federal mandate. But given the nature of the relevant 

CWA provisions — and particularly the maximum extent practicable standard —

it is wrong to assume that the conditions at issue in this case exceed what is 

necessary to comply with the CWA simply because neither the statute nor its 

regulations explicitly mention those conditions. The consequence of that 

assumption, moreover, risks discouraging the state from assuming cooperative 

federalism responsibilities — and may even encourage the state to withdraw from 
11

administering the NPDES. Indeed, counsel for the state indicated at oral argument 

that if the Commission‘s reasoning were upheld — and the state were required to 

foot the bill for any conditions not expressly mentioned in the applicable federal 

statutes or regulations — it might think twice about entering into such 

arrangements of cooperative federalism. 

In light of these concerns with the Commission‘s approach to this case, it is 

difficult to see the basis for — or utility of — upholding the Commission‘s 

decision, even under the inscrutable standard of review the majority employs. 

(See California Youth Authority v. State Personnel Bd. (2002) 104 Cal.App.4th 

575, 586 [substantial evidence review requires that all evidence be considered, 

including evidence that does not support the agency‘s decision]; see also Sierra 

Club v. U.S. Army Corps of Engineers (2d Cir. 1983) 701 F.2d 1011, 1030 [―the 

court may properly be skeptical as to whether an [agency report‘s] conclusions 

have a substantial basis in fact if the responsible agency has apparently ignored the 

conflicting views of other agencies having pertinent expertise‖].) The better 

course, in my view, would be for us to articulate the appropriate standard for 

evaluating the question whether these permit conditions are state mandates and 

then remand for the Commission to apply it in the first instance.

II.

The Commission relied on a narrow approach that only compares the terms 

of a permit with the text of the CWA and its implementing regulations. Instead, 

the Commission should have employed a more flexible methodology in 

determining whether the permit conditions were federally mandated. Such a 

flexible approach accords with our prior case law. (See City of Sacramento, 

supra, 50 Cal.3d at p. 76 [whether local government appropriations are federally 

mandated and therefore exempt from taxing and spending limitations under 

section 9, subdivision (b), of article XIII B of the California Constitution depends 
12

on, inter alia, the nature and purpose of the federal program, whether its design 

suggests an intent to coerce, when state or local participation began, and the legal 

and practical consequences of nonparticipation or withdrawal].) Moreover, it 

would have the added benefit of not discouraging the state from participating in 

ventures of cooperative federalism.

The majority may be correct that the facts of City of Sacramento are 

distinguishable. (See maj. opn., ante, at p. 21.) In that case, the state risked 

forsaking subsidies and tax credits for its resident businesses if it failed to comply 

with federal law requiring that unemployment insurance protection be extended to 

local government employees. (Id. at p. 15.) Here, in contrast, the negative 

consequences of failing to comply with federal law may seem less severe, at least 

in fiscal terms: the EPA may determine that the state is not in compliance with the 

CWA and reassert authority over permitting. (See 33 U.S.C. § 1342(c)(3).) But 

City of Sacramento nonetheless remains relevant, even though a precisely 

comparable level of coercion may not exist here. The flexible approach we 

articulated in that case remains the best way to ensure that some weight is given to 

the Regional Board‘s technical expertise, and the conclusions resulting therefrom, 

while also taking account of the cooperative federalism arrangements built into the 

CWA.

So instead of adopting an approach foreign to our precedent, the 

Commission should have begun its analysis with the statutory and regulatory text 

— and then it should have considered other relevant materials and record evidence 

bearing on whether the permit conditions are necessary to satisfy federal law. 

Crucially, such evidence includes how the federal regulatory scheme operates in 

practice. The Commission could have examined, for instance, previous permits 

issued by the EPA in similarly situated jurisdictions, comparing them to the 

inspection and trash receptacle requirements the Regional Board imposed here and 
13

giving due consideration to the EPA‘s conclusion that the maximum extent 

practicable standard is applied in a highly site-specific and flexible manner in 

order to account for unique local challenges and conditions. (See 64 Fed. Reg. 

68722, 68754 (Dec. 8, 1999).) The Commission could also have considered 

whether, instead of identifying permitting conditions necessary to comply with the 

CWA, the state shifted onto local governments responsibility to conduct 

inspections or provide trash receptacles. The majority wisely notes that these are 

factors the Commission could have examined. (See maj. opn., ante, at pp. 24-27.) 

But the Commission mentioned this evidence only briefly, failing to grapple in 

any meaningful way with its implications for the issue at hand. We should allow 

the Commission an opportunity to do so in the first instance.

The Commission should have also accorded appropriate deference to the 

Regional Board‘s conclusions regarding how best to comply with the federal 

maximum extent practicable standard. One way to ensure that such deference is 

given would be to place on the party seeking reimbursement the burden of 

demonstrating that the challenged permit conditions clearly exceed the federal 

standard, or that they were otherwise unnecessary to reduce pollutant discharges to 

the maximum extent practicable. Doing so would make sense where the state is 

implementing a federal program that envisions routine state participation, the 

federal program does not itself define the minimum degree of compliance 

required, and the state‘s implementing agency reasonably determines in its 

expertise that certain conditions are necessary to comply with the applicable 

federal standard.

* * *

The Commission‘s decision — and the approach that produced it — fails to 

accord with existing law and with the nature of the applicable federal scheme. 

The state is not responsible for reimbursing localities for permit conditions that are 
14

necessary to comply with federal law, a circumstance that renders interpretation of 

the CWA central to this case. A core principle of the CWA is to facilitate 

cooperative federalism, by allowing states to take on a critical responsibility in 

exchange for compliance with a set of demanding standards overseen by a federal 

agency capable of withdrawing approval for noncompliance. (See Arkansas v. 

Oklahoma (1992) 503 U.S. 91, 101 [―The Clean Water Act anticipates a 

partnership between the States and the Federal Government, animated by a shared 

objective:  ̳to restore and maintain the chemical, physical, and biological integrity 

of the Nation‘s waters‘ ‖]; Shell Oil Co. v. Train (9th Cir. 1978) 585 F.2d 408, 409 

[―Shell‘s complaint must be read against the background of the cooperative 

federal-state scheme for the control of water pollution‖].) The Commission failed 

to interpret the statute in light of nuances in its text and structure. And it failed to 

offer even a modicum of deference to the Regional Board‘s interpretation, despite 

the Board‘s clear expertise that the technical nature of the questions necessary to 

interpret the scope of the CWA demands.

Accordingly, I would remand the matter to the Court of Appeal with 

directions that it instruct the Commission to reconsider its decision. On 

reconsideration, the Commission should appropriately defer to the Regional 

Board, consider all relevant evidence bearing on the question at hand, and ensure 

the evidence clearly shows the challenged permit conditions were not necessary to 

comply with the federal mandate. This is the standard that most thoroughly 

reflects our existing law and the nature of the CWA. Any dilution of it 

exacerbates the risk of undermining the nuanced federal-state arrangement at the 

heart of the CWA.
