Water Quality Standards for Kansas

AGENCY: Environmental Protection

Agency.

ACTION: Proposed rule.

SUMMARY: EPA is proposing water

quality standards for the State of

Kansas. If promulgated as final

standards, they would supersede

aspects of Kansas’s water quality

standards that EPA disapproved in

1998. In furtherance of EPA’s 1998

disapproval action, EPA is proposing:

that all discharges to stream segments

for which continuous flow is sustained

primarily through the discharge of

treated effluent shall protect the States’

designated uses; 7Q10, 4B3, or other

scientifically defensible design flows

approved by EPA shall be used to

implement the State’s chronic aquatic

life criteria; 1Q10, 1B3, or other

scientifically defensible design flows

approved by EPA shall be used to

implement the State’s acute aquatic life

criteria; implementation procedures for

use when applying the States’

antidegradation policy to determine

whether to allow a lowering of surface

water quality by point sources of

pollution where nonpoint sources also

contribute the pollutant of concern to

that body of water; an aquatic life use

for one stream segment and a primary

contact recreation use for 1,292 stream

segments and 164 lakes.

In addition, under its discretionary

authority to address State standards that

the Administrator determines are

inconsistent with the Clean Water Act,

EPA is proposing: that water quality

standards in Kansas apply to all

privately owned surface waters in

Kansas that are waters of the U.S.; and

numeric human health criteria for

alpha- and beta-endosulfan.

DATES: EPA will accept public

comments on this proposed rule until

September 1, 2000. Comments

postmarked after this date may not be

considered. On July 27, 2000, EPA is

holding two public hearings on today’s

proposed water quality standards for

Kansas.

ADDRESSES: An original plus 2 copies,

and if possible an electronic version of

comments either in WordPerfect or

ASCII format, should be addressed to

Ann Jacobs at jacobs.ann@epa.gov or at

U.S. EPA Region VII, Water Resources

Protection Branch, 901 North 5th Street,

Kansas City, Kansas 66101.

I. Potentially Affected Entities

Citizens concerned with water quality

in Kansas may be interested in this

proposed rulemaking. Entities

discharging pollutants to waters of the

United States in Kansas could be

indirectly affected by this proposed

rulemaking since water quality

standards are used in determining water

quality-based National Pollutant

Discharge Elimination System (NPDES)

permit limits. Categories and entities

that may indirectly be affected include:

Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules 41217

Category Examples of potentially

affected entities

Industry ............... Industries discharging pollutants to surface waters in Kansas.

Municipalities ...... Publicly-owned treatment

works discharging pollutants to surface waters in Kansas.

This table is not intended to be

exhaustive, but rather provides a guide

for readers regarding NPDES entities

likely to be affected by this action. This

table lists the types of entities that EPA

is now aware could potentially be

affected by this action. Other types of

entities not listed in this table could

also be affected. To determine whether

your facility may be affected by this

action, you should carefully examine

today’s proposed rule. If you have

questions regarding the applicability of

this action to a particular entity, consult

the person listed in the preceding FOR

FURTHER INFORMATION CONTACT section.

II. Background

A. What Are the Statutory and

Regulatory Requirements That Are

Relevant to This Action?

Under section 303(c) of the Clean

Water Act (CWA), 33 U.S.C. 1313(c),

States and Tribes are required to

develop water quality standards for

waters of the United States within their

jurisdiction. Section 303(c) and EPA’s

implementing regulations at 40 CFR part

131 require State water quality

standards to include the designated use

or uses to be made of the water, the

criteria necessary to protect those uses,

and an antidegradation policy. States

are required to review their water

quality standards at least once every

three years and, if appropriate, revise or

adopt new standards. 33 U.S.C. 1313(c).

States are required to submit the results

of these triennial reviews to EPA. EPA

is to approve or disapprove any new or

revised standards. States may include in

their standards policies generally

affecting the standards’ application and

implementation. See 40 CFR 131.13.

These policies are subject to EPA review

and approval. See 40 CFR 131.6(f), 40

CFR 131.13. Section 303(c)(4) of the

CWA authorizes EPA to promulgate

water quality standards when necessary

to supersede disapproved State water

quality standards, or in any case where

the Administrator determines that new

or revised standards are necessary to

meet the requirements of the CWA.

B. What Actions Have Kansas and EPA

Taken Leading to Today’s Action?

On October 31, 1994, Kansas

submitted a complete set of water

quality standards to EPA for review and

approval. In a February 19, 1998, letter

from U. Gale Hutton, Region VII

Director of the Water, Wetlands and

Pesticides Division, to Gary R. Mitchell,

Secretary of the Kansas Department of

Health and Environment (KDHE), EPA

reviewed and approved in part and

disapproved in part all of the State’s

new or revised standards. Specifically,

EPA’s letter of February 19, 1998,

(hereafter EPA’s 1998 disapproval letter

or EPA’s 1998 action) disapproved the

following provisions of Kansas’ 1994

water quality standards:

• The State’s antidegradation policy

to the extent that it applied to

protections for so-called Tier 3 waters;

• Provisions governing discharges

from waste stabilization ponds;

• Disinfection requirements;

• Provisions addressing the adoption

of water quality criteria for the

protection of the State’s domestic water

supply use;

• A number of water quality criteria;

• The State’s water quality standards

implementation procedures;

• The State’s antidegradation

implementation procedures;

• Use designations for 1,485 waters

with classified uses;

• The State’s water quality standards

provisions for assumed stream design

flows in applying water quality criteria;

and,

• Provisions relating to waters with

effluent-created habitat.

In the letter disapproving these

provisions, Region VII also stated that it

was requesting the EPA Administrator

to make a determination under CWA

section 303(c)(4)(B) that an existing

provision in the State’s water quality

standards that exempted certain

privately owned surface waters from the

State’s water quality standards is

inconsistent with the CWA to the extent

it exempts privately owned surface

waters that are waters of the United

States.

In June 1999, Kansas completed a

triennial review of its water quality

standards. As part of that review,

Kansas adopted revisions to the Kansas

Administrative Regulations (K.A.R.),

Title 28, Article 16, on June 29, 1999,

including the adoption of new or

revised water quality standards. These

new or revised water quality standards

became effective under State law on

June 30, 1999. (These revisions are

hereafter referred to as the 1999

revisions to the Kansas water quality

standards.) Kansas submitted these

standards for EPA review and approval

on August 10, 1999, as required under

Federal regulations at 40 CFR 131.5. In

its submission, KDHE corrected several

provisions disapproved by EPA in its

February 1998 disapproval letter to

make them consistent with the CWA. By

letter dated January 19, 2000, EPA

Region VII approved many of these new

or revised portions of the States’ water

quality standards. EPA’s approval of

these new or revised standards

eliminated the need for a Federal

promulgation to correct many of the

previously disapproved provisions.

These provisions are discussed in

section III.

Today’s proposal addresses the

remaining standards disapproved by

EPA in its 1998 action by proposing

replacement water quality standards for

the State of Kansas. The proposed

regulations are discussed in section IV.

III. What Disapproved Provisions Have

Been Addressed?

As discussed in section II. B., Kansas

completed its most recent triennial

review in June 1999 and submitted the

resulting new or revised water quality

standards to EPA for review and

approval on August 10, 1999. By letter

dated January 19, 2000, EPA Region VII

approved the submission in part and

disapproved it in part. Among the

provisions approved by EPA were new

or revised water quality standards that

addressed provisions previously

disapproved by EPA in its 1998 action.

In the case of the standards changes

discussed later in this section, EPA in

its January 19, 2000, letter determined

that Kansas adopted new or revised

standards consistent with the CWA and

EPA’s implementing regulations. Under

CWA section 303(c)(4), this action by

Kansas eliminated the need for EPA to

promulgate replacement water quality

standards addressing these provisions.

Therefore, EPA is not proposing water

quality standards for the following

provisions.

A. Antidegradation Policy To Protect

Outstanding Natural Resource Waters

The State of Kansas revised portions

of its antidegradation provisions at

K.A.R. 28–16–28c(a) as part of its

triennial review in 1994. In its 1998

action, EPA disapproved a portion of

the State’s antidegradation provisions

because the provisions failed to include

an appropriate level of protection for

high quality waters constituting

outstanding national resource waters

(ONRWs) as required by 40 CFR

131.12(a)(3). This level of protection is

commonly referred to as ‘‘Tier 3.’’ The

41218 Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules

State’s 1994 submittal included specific

revisions to mixing zone provisions at

K.A.R. 28–16–28c(b)(2)(C)(i) that

provided for placement of mixing zones

in what Kansas identified as its

Outstanding Natural Resource Waters,

allowing a permanent lowering of water

quality in at least a portion of such

waters. This modification to the State

regulations reduced the level of

protection that previously had been

provided to the State’s Outstanding

Natural Resource Waters and was not

consistent with Federal regulations

requiring that the water quality of

ONRWs be maintained and protected.

EPA’s interpretation of the Federal

requirements for ONRWs emphasizes

restriction of new or increased

discharges to such waters. Although this

interpretation of the regulation is not

the only means of assuring that the

water quality will be maintained and

protected in ONRWs, the new or revised

State water quality standards of 1994

deviated significantly from this level of

protection and provided no

commensurate level of protection.

Without providing a level of protection

equivalent to that provided under 40

CFR 131.12(a)(3), the State

antidegradation policy was not

complete because it did not provide for

a category of waters where new or

increased discharges are prohibited.

Regardless of whether there are current

or future State waters designated as

ONRWs, the State’s water quality

standards must provide the opportunity

for such designation.

As part of its 1999 revisions to the

Kansas water quality standards, the

State added a fourth level of protection

under its antidegradation provisions.

The States’ standards now include a

definition for outstanding national

resource waters, which include surface

waters or surface water segments of

extraordinary recreational or ecological

significance, and which are to be

afforded the highest level of water

quality protection under the

antidegradation provisions. Kansas’ new

or revised water quality standards at

K.A.R. 28–16–28c(a)(3) require

maintenance and protection of existing

uses and existing water quality in these

waters with a prohibition against new or

expanded discharges. In its review of

these new or revised provisions, EPA

determined by letter dated January 19,

2000, that the State’s 1999 revisions to

the water quality standards provide

protection to high quality waters

constituting an outstanding national

resource as required at 40 CFR

131.12(a)(3). EPA’s approval of the

State’s revision eliminated the need for

EPA to promulgate Federal replacement

water quality standards for Tier 3

protection.

B. Waste Stabilization Ponds

As part of the State’s 1994 revision of

its water quality standards, Kansas

adopted a provision at K.A.R. 28–16–

28c(d)(3) that waived NPDES permitting

requirements for determining the

reasonable potential of certain waste

stabilization pond discharges to violate

water quality standards for ammonia

and fecal coliform bacteria. In its 1998

disapproval letter, EPA stated that this

provision circumvented the application

of water quality standards and would

not ensure that such discharges meet

State water quality standards as

required by 40 CFR 122.44(d).

In its 1999 revisions to its water

quality standards, Kansas removed

K.A.R. 28–16–28c(d)(3) from the State’s

water quality standards regulations.

EPA approved this revision to the

State’s water quality standards on

January 19, 2000, eliminating the need

for promulgation of Federal standards.

C. Disinfection Requirements

In its February 19, 1998, disapproval

letter to KDHE, EPA also disapproved

revised regulations at K.A.R. 28–16–

28c(d)(4), which allowed dischargers to

avoid disinfection requirements

regardless of a water body’s designation

for primary contact recreation. The

State’s regulations at K.A.R. 28–16–

28c(d)(4) required disinfection of

wastewater only if the KDHE

determined that such a discharge will

result in a threat to public health. This

provision relied on information

indicating whether or not the water

body is known or likely to be used for

either primary or secondary recreation,

or domestic water supply, rather than

upon the waterbody’s use designation

specified in the State’s water quality

standards.

In its 1998 disapproval of this

provision, EPA stated that the need for

disinfection of wastewater effluent must

be a function of the need to protect

designated uses based on a

determination that the discharge has a

reasonable potential to cause or

contribute to an excursion of applicable

water quality standards, regardless of

any demonstration at the time of permit

issuance regarding whether the public

actually utilizes that water body for the

use or uses designated in the States’

standards. Because all waters of the

State are designated for secondary

contact recreation by default,

implementation of this provision could

potentially undermine the State’s efforts

to comply with Federal regulations at 40

CFR 122.44(d) in writing limitations for

NPDES permits that derive from and

comply with State water quality

standards and, specifically, protect

designated uses.

As part of Kansas’ 1999 revisions to

its water quality standards, this

provision was revised and moved to

K.A.R. 28–16–28e(c)(7)(D). EPA

approved this revision on January 19,

2000, because it now requires

disinfection of wastewater where there

is a reasonable potential for discharges

to exceed the applicable criteria

supporting the assigned recreational use

designation. EPA’s approval of the 1999

revision to the State’s water quality

standards regarding disinfection

requirements eliminated the need for

promulgation of Federal standards.

D. Domestic Water Supply Criteria

In its 1998 disapproval, EPA

disapproved K.A.R. 28–16–28e(c)(3)(C)

because it appeared to limit State

adoption of water quality criteria for the

protection of domestic water supplies to

levels equivalent to the Federally

adopted maximum contaminant levels

(MCLs) under section 1412 of the Safe

Drinking Water Act (SDWA), 42 U.S.C.

300g-1. EPA was concerned that this

provision, in appearing to require the

adoption of criteria equal to MCLs,

restricted the State’s authority to adopt

criteria necessary to protect domestic

water supplies for pollutants for which

EPA has not published MCLs, even

though EPA has published

recommended water quality criteria

under section 304(a) of the CWA for this

purpose. A State regulation authorizing

the State to adopt criteria only for

pollutants for which EPA has

promulgated MCLs is inconsistent with

Federal regulations at 40 CFR 131.11(a),

which requires that States adopt water

quality criteria necessary to protect the

designated uses. Such criteria ‘‘must

contain sufficient parameters or

constituents to protect the designated

use.’’ K.A.R. 28–16–28e(c)(3)(C)

appeared to restrict the State from

meeting this requirement, and for that

reason EPA disapproved the provision

in 1998.

In response to EPA’s 1998 action,

KDHE clarified that this provision did

not limit the State’s authority to go

beyond the MCLs when adopting water

quality criteria for its domestic water

supply. KDHE identified pollutants for

which it had adopted numeric water

quality criteria applicable to the

domestic water supply use based on

EPA’s recommended section 304(a)

criteria for those pollutants, even

though EPA had not published MCLs for

them under the SDWA. Although there

continue to be gaps in domestic water

Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules 41219

supply criteria for specific pollutants

within the State’s standards, EPA

believes the State demonstrated that

EPA’s original interpretation of this

provision was in error. As a result of the

State’s clarification that it has the

authority to adopt water quality criteria

applicable to its domestic water supply

use under K.A.R. 28–16–28e(c)(3)(C)

based on EPA’s published section 304(a)

criteria, EPA determined that this

provision of the State’s water quality

standards is consistent with the CWA

and EPA’s implementing regulations.

Therefore, in its January 19, 2000, letter,

EPA withdrew its 1998 disapproval and

approved the provision, thereby

eliminating the need for a Federal

promulgation.

E. EPA Review of Kansas’ 1994 and

1999 Water Quality Criteria for Toxic

Pollutants

a. 1994 Revisions to Kansas Water

Quality Standards

In its 1994 revisions of its water

quality standards, Kansas adopted

numeric water quality criteria for many

pollutants for which it previously had

none. Kansas also revised existing

single-value criteria to separately

address both acute and chronic toxicity.

In its 1998 action, EPA approved 89

separate water quality criteria for toxics

for the protection of aquatic life and

human health adopted by the State as

fully consistent with the requirements

of the CWA and EPA’s implementing

regulations. All of the State-adopted

water quality criteria approved by EPA

in 1998 were equal to or more stringent

than those Federal criteria previously

promulgated by EPA for Kansas under

the NTR in 1992. (See Enclosure B,

Table B., February 19, 1998, letter from

EPA to the Kansas Department of Health

and Environment.) With that approval

decision, the numeric water quality

criteria that EPA had promulgated for

Kansas for those pollutants as part of the

NTR were no longer necessary.

Therefore, EPA withdrew the Federal

criteria (65 FR 19659, April 12, 2000).

EPA, in its 1998 action, also

disapproved a number of water quality

criteria for both aquatic life and human

health protection that EPA determined

did not protect the State’s designated

uses. Of the State-adopted criteria

disapproved by EPA, a large number of

the pollutants were already addressed

by Federally-promulgated criteria in the

NTR. Because the NTR criteria for these

pollutants continue to apply in Kansas,

no further action by EPA is necessary at

this time. In its 1998 action, EPA also

disapproved water quality criteria for

pollutants that were not included in the

1992 NTR for Kansas. EPA identified

these pollutants as candidates for future

promulgation should the State fail to

adopt water quality criteria which

protect designated uses or to provide

adequate scientific justification for not

having them.

b. 1999 Revisions to the Kansas Water

Quality Standards

On June 29, 1999, the State of Kansas

completed another set of revisions to its

water quality standards regulations and

submitted them for EPA’s review and

approval on August 10, 1999. In that

action, Kansas revised a number of its

water quality criteria for both aquatic

life and human health protection to

address criteria previously disapproved

by EPA in 1998. Many of those revised

criteria were approved by EPA on

January 19, 2000. Where the State

adopted water quality criteria that are

equal to or more stringent than the

applicable Federal criteria promulgated

for Kansas under the NTR, EPA

withdrew the Federal criteria (65 FR

19659, April 12, 2000). EPA also

approved water quality criteria adopted

by the State in 1999 that were less

stringent than those Federal criteria

promulgated for Kansas in the NTR but

that were consistent with the Clean

Water Act. In a separate, upcoming

action, EPA will propose to withdraw

Kansas from the NTR for those

pollutants.

In its 1999 revisions, Kansas also

submitted water quality criteria for

pollutants not included in the NTR for

Kansas. Those revised criteria were

intended to address criteria disapproved

by EPA in its 1998 action. EPA

approved the 1999 water quality criteria

where EPA determined that they were

based on scientifically defensible

methods and protected designated uses.

In its January 19, 2000, approval of

Kansas’ 1999 submission of revised

water quality standards, EPA approved

acute and chronic aquatic life quality

criteria for nickel and zinc; acute

aquatic life criteria for silver; human

health criteria (water and organism) for

thallium; and human health criteria

(organism only) for alpha-and betaendosulfan. The new or revised water

quality criteria adopted by Kansas on

June 29, 1999, and approved by EPA on

January 19, 2000, address EPA’s

disapproval in its 1998 action.

Therefore, no further action by EPA is

necessary for those pollutants.

Several water quality criteria adopted

by the State in 1994 and disapproved by

EPA in 1998 were not corrected by the

State in its 1999 revisions to its water

quality standards. For those pollutants

that are already subject to Federally

promulgated water quality criteria, no

further EPA action is necessary in

response to the 1998 disapproval action

because Kansas remains in the NTR for

those pollutants. In many instances, the

State withdrew its EPA-disapproved

water quality criteria as part of its 1999

revisions and replaced State criteria

with a footnote acknowledging there are

Federal criteria in place. Because an

acknowledgment of existing Federal

water quality standards within Kansas

regulations does not constitute actual

adoption of water quality criteria by the

State, EPA is leaving the existing

Federal water quality standards in

place.

c. EPA Withdrawal of 1998 Disapproval

In its 1998 review of the 1994 Kansas

water quality standards revisions, EPA

disapproved State water quality criteria

for alpha-endosulfan and betaendosulfan for the State’s Domestic

Water Supply use as being inconsistent

with the requirements of the CWA and

EPA’s implementing regulations. This

disapproval was procedurally in error

however, because the State had not

adopted any new or revised criteria for

the Domestic Water Supply use for

those pollutants in 1994 that would

have triggered EPA’s approval or

disapproval authority.

d. Water Quality Criteria for Endrin

In 1994, the State adopted a new

criterion for endrin for its Domestic

Water Supply use, which EPA

disapproved in its 1998 action under

section 303(c)(3). In its 1999 revision,

the State removed the numeric criterion

for endrin altogether. EPA subsequently

found that its 1998 disapproval of the

numeric criterion for endrin had been in

error. The State’s 1994 criterion was

consistent with the CWA and was based

on the drinking water MCL for endrin

(and no Kansas NTR value for endrin

had been promulgated). Therefore, on

January 19, 2000, EPA withdrew its

1998 disapproval of Kansas’s 1994

endrin criterion and disapproved the

State’s 1999 deletion of the endrin

criterion. EPA disapproved this deletion

because it had the effect of leaving the

State with no criterion for endrin in its

Domestic Water Supply use. If the State

fails to address this deficiency, EPA will

propose water quality criteria for

endrin, in a separate action, at the same

time it addresses the other provisions

EPA disapproved on January 19, 2000.

F. Antidegradation and Water Quality

Standards Implementation Procedures

As part of the Kansas’ 1994

submission, KDHE submitted

procedures for the implementation of its

41220 Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules

standards through the development of

NPDES permit limitations (Kansas

Surface Water Quality Implementation

Procedures; October, 18, 1994). These

procedures contain two separate

components: procedures for

implementing the State’s

antidegradation policy at K.A.R. 28–16–

28c(a), and procedures governing the

implementation of water quality

standards, e.g., through development of

water quality-based effluent limitations

for NPDES permits.

In its 1998 action, EPA addressed

components of these procedures

separately based on their distinctly

different treatment under Federal

regulations. Federal regulations at 40

CFR 131.12(a) require that States

identify methods for implementing the

State’s antidegradation policy.

Development of these implementation

procedures is not discretionary. Section

3 of the State’s procedures addressed

implementation of the State’s

antidegradation policy. In its 1998

disapproval of Kansas’ October 18,

1994, antidegradation implementation

procedures, EPA identified three

deficiencies with the procedures that

would lead to the implementation of

Kansas’ antidegradation policy in a

manner inconsistent with Federal

regulations. These deficiencies were: (1)

Failure to maintain existing water

quality for Tier 3 waters; (2) Failure to

maintain existing water quality for Tier

2 waters under the State’s

antidegradation provision; and (3)

Failure to identify the means by which

the State would implement its

antidegradation policy in the context of

determining whether to allow a

lowering of surface water quality by

point sources of pollution where

nonpoint sources also contribute the

pollutant of concern to that body of

water. The State revised it’s

antidegradation procedures and

submitted them to EPA for review in

1999. These revised procedures

addressed the first two disapproved

items regarding existing water quality in

Tier 3 and Tier 2 waters, but not the

third disapproved item. This last item

remains disapproved and is addressed

in section IV.D.

The 1994 antidegradation procedures

required the protection of existing water

quality within the State’s Outstanding

Natural Resource Waters, but did not

describe the mechanisms or methods by

which that level of protection was to be

implemented. Specifically, the

Procedures failed to identify how

existing water quality in the State’s

Outstanding Natural Resource Waters

would be maintained under the mixing

zone provisions at K.A.R. 28–16–

28c(b)(2). The use of mixing zones and

zones of initial dilution in the State’s

Outstanding Natural Resource Waters

allowed for the permanent lowering of

existing water quality in portions of

those waters.

The State’s 1994 Procedures also did

not adequately protect high quality

waters as required under Federal

regulations at 40 CFR 131.12(a)(2)

(referred to as ‘‘Tier 2’’) and the State

provision at K.A.R. 28–16–28c(a)(2).

The Tier 2 level of protection under the

Federal antidegradation regulations and

the State antidegradation policy requires

protection of existing water quality

unless a lowering of water quality is

necessary to accommodate important

social or economic development in the

area where the lowering of existing

water quality occurs. However, the State

procedure only addressed the protection

of existing and designated uses in

regulating point sources of pollution

rather than existing water quality. This

is contrary to the State provision at

K.A.R. 28–16–28c(a)(2) and is also

inconsistent with 40 CFR 131.12(a)(2).

As part of its June 29, 1999, revisions

to its water quality standards, the State

revised its antidegradation

implementation procedures in a manner

consistent with revisions to the State’s

antidegradation policy (see section

III.A.) to maintain existing water quality

in Tier 3 waters. Kansas’ 1999 revision

of its antidegradation implementation

procedures also adequately addressed

the manner in which the maintenance of

existing water quality is ensured for

high quality waters (Tier 2). EPA

approved these revisions in its January

19, 2000, letter. These corrections to the

State’s Procedures made further Federal

action to address these two disapproved

provisions unnecessary.

The remaining provisions of the

State’s 1994 implementation procedures

addressed implementation of water

quality standards. Federal regulations at

40 CFR 131.13 address policies

generally affecting the application and

implementation of standards that States

may adopt, at their discretion. If a State

adopts such policies, the regulation

provides that they are subject to EPA

review and approval. In its 1998 action,

EPA disapproved the State’s

implementation procedures for NPDES

permits because the procedures did not

ensure that permits would derive from

and comply with the State’s water

quality standards. Specifically, EPA

identified the following deficiencies.

First, the procedures failed to clearly

identify how mixing zones were to be

limited or sized. Second, the procedures

addressing whole effluent toxicity

(WET) testing allowed the use of less

sensitive organisms than recommended

in the testing methodology and did not

identify any circumstances when WET

limitations would be placed in NPDES

permits when there was reasonable

potential to violate the State’s narrative

water quality criteria. Third, the

procedures specified a ‘‘lesser level of

evaluation’’ for minor permits than is

specified for major permits. Finally, the

procedures did not include provisions

addressing site-specific water quality

criteria development, the issuance of

variances or the manner by which the

State would measure and evaluate

socio-economic impacts.

In its 1999 revisions to its water

quality standards, Kansas significantly

revised its implementation procedures

(Kansas Implementation Procedures:

Surface Water, June 1, 1999) and

corrected the deficiencies identified in

EPA’s 1998 disapproval letter.

Additionally, the State incorporated its

implementation procedures into the

State’s water quality regulations at

K.A.R. 28–16–28b(cc). These revised

implementation procedures, to the

extent they addressed water quality

standards implementation, were

reviewed by EPA and approved on

January 19, 2000.

IV. What Federal Water Quality

Standards Is EPA Proposing in

Response to Its 1998 Disapproval?

A. Designated Uses

1. Background

Section 101(a)(2) of the CWA

establishes as a national goal ‘‘water

quality which provides for the

protection and propagation of fish,

shellfish, and wildlife and * * *

recreation in and on the water,’’

wherever attainable. This national goal

is commonly referred to as the

‘‘fishable/swimmable’’ goal of the CWA.

(Hereafter, the fishable/swimmable

goals are referred to as CWA section

101(a) goal uses.) Section 303(c)(2)(A)

requires State water quality standards to

‘‘protect the public health and welfare,

enhance the quality of water, and serve

the purposes of this Act.’’ EPA’s

regulations at 40 CFR part 131 interpret

and implement these CWA provisions

by requiring that water quality

standards provide for CWA section

101(a) goal uses unless those uses have

been shown to be unattainable,

effectively creating a rebuttable

presumption of attainability, i.e., a

default designation of CWA section

101(a) goal uses should apply. The

mechanism in EPA’s regulations used to

rebut this presumption is a use

attainability analysis.

Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules 41221

Under 40 CFR 131.10(j), States are

required to conduct a use attainability

analysis (UAA) whenever the State

designates or has designated uses that

do not include the CWA section 101(a)

goal uses, or when the State wishes to

remove CWA section 101(a) goal uses,

or when it adopts subcategories of uses

that require less stringent criteria. Uses

are considered by EPA to be attainable,

at a minimum, if the uses can be

achieved (1) when effluent limitations

under section 301(b)(1)(A) and (B) and

section 306 are imposed on point source

dischargers, and (2) when cost effective

and reasonable best management

practices are imposed on nonpoint

source dischargers. See 40 CFR

131.10(d). EPA’s regulations at 40 CFR

131.10 list grounds upon which to base

a finding that attaining the designated

use is not feasible, as long as the

designated use is not an existing use. A

UAA is defined in 40 CFR 131.3(g) as

a ‘‘structured scientific assessment of

the factors affecting the attainment of

the use which may include physical,

chemical, biological, and economic

factors.’’ In a UAA, the physical,

chemical and biological factors affecting

the attainment of a use are evaluated

through a water body survey and

assessment. Guidance on water body

survey and assessment techniques is

contained in the Technical Support

Manual, Volumes I–III: Water Body

Surveys and Assessments for

Conducting Use Attainability Analyses.

Volume I provides information on water

bodies in general, Volume II contains

information on estuarine systems and

Volume III contains information on lake

systems. (Volumes I–II, November 1983;

Volume III, November 1984). Additional

guidance is provided in the Water

Quality Standards Handbook: Second

Edition (EPA–823–B–94–005, August

1994). Guidance on economic factors

affecting the attainment of a use is

contained in the Interim Economic

Guidance for Water Quality Standards:

Workbook (EPA–823–B–95–002, March

1995).

As discussed earlier, EPA regulations

effectively establish a ‘‘rebuttable

presumption’’ that CWA section 101(a)

goal uses are attainable and therefore

should apply to a water body unless it

is affirmatively demonstrated that such

uses are not attainable. EPA adopted

this approach in order to help achieve

the national goal articulated by Congress

that, ‘‘wherever attainable,’’ water

quality should provide for the

‘‘protection and propagation of fish,

shellfish and wildlife’’ and for

‘‘recreation in and on the water.’’ CWA

101(a). While facilitating achievement of

Congress’ goals, the ‘‘rebuttable

presumption’’ approach preserves

States’ paramount role in establishing

water quality standards in weighing any

available evidence regarding the

attainable uses of a particular water

body. The rebuttable presumption

approach does not restrict the discretion

that States have to determine that CWA

section 101(a) goal uses are not, in fact,

attainable in a particular case. Rather, if

the water quality goals articulated by

Congress are not to be met in a

particular water body, the regulations

simply require that such a

determination be based upon a credible,

‘‘structured scientific assessment’’ of

use attainability. See 40 CFR 131.3(g)

(defining use attainability analysis).

EPA believes that the rebuttable

presumption policy reflected in these

regulations is an essential foundation

for effective implementation of the CWA

as a whole. The ‘‘use’’ of a water body

is the most fundamental articulation of

its role in the aquatic and human

environments, and all of the water

quality protections established by the

CWA follow from the water’s designated

use. If a use lower than a CWA section

101(a) goal use is designated based on

inadequate information or superficial

analysis, water quality-based

protections that might have enabled the

water to achieve the goals articulated by

Congress in section 101(a) may not be

put in place. As a result, the true

potential of the water body may never

be realized, and a resource highly

valued by Congress and the public may

be forever lost.

EPA seeks, through its oversight

under section 303(c) of the Act, to

ensure that any State’s decision to forgo

protection of a water body’s potential to

support CWA section 101(a) goal uses

results from an appropriately

‘‘structured’’ analysis of use attainment.

Where EPA concludes that the State

failed to adequately justify a use

designation lower than a CWA section

101(a) goal use designation, EPA

disapproves the use designation. In

some cases, the State may decide to

revise its use classifications to protect

CWA section 101(a) goal uses. In other

cases, the State may decide to conduct

a more thorough analysis of use

attainability sufficient to rebut the

rebuttable presumption reflected in the

regulations. Where, however, a State

does neither, federally promulgated

CWA section 101(a) goal uses will

ensure the water quality goals of the Act

are effectively implemented.

2. EPA Review of Kansas’ Use

Designations

When Kansas submitted its revised

standards to EPA on October 31, 1994,

it also submitted the Kansas Surface

Water Register, which contains the

listing of all streams, lakes and wetlands

classified under the State’s water quality

standards, individual water body

locational data and all designated uses

for each stream segment, wetland and

lake. The Register, adopted by reference

at K.A.R. 28–16–28d(c)(2), greatly

expanded the number of streams

previously designated under the 1985

Kansas standards, dividing each original

stream segment into multiple parts, with

independent designations for each

newly identified segment. Given both

the extensive restructuring of the

citations for classified stream segments

and the creation of the Register separate

from the K.A.R., EPA treated all of the

1994 use designations as new or revised

water quality standards subject to EPA

approval under section 303(c)(3) of the

CWA. In the 1994 revision to Kansas’

water quality standards, the State listed

a number of streams and lakes that it

determined did not support a primary

contact recreation use or aquatic life

protection use, or that were simply

undesignated because Kansas reported

that it had limited or no field

information to make a CWA section

101(a) goal use designation. In 1998, of

these waters, EPA disapproved nine

water body designations because it

determined that the use attainability

analyses submitted by Kansas were

inadequate, and it disapproved one

water body designation for which the

State failed to submit a use attainability

analysis to justify the omission of the

CWA section 101(a) goal uses. EPA also

disapproved Kansas’ failure to designate

any uses at all for another 1,475 waters.

Since the early 1980’s, EPA has

identified the State’s lack of justification

for waters not designated with section

101(a) goal uses, particularly primary

contact recreation, as a significant issue

that must be addressed. EPA approved

the 1985 revisions to the Kansas water

quality standards on June 19, 1986,

based on ‘‘completion of the statewide

use attainability analyses in accordance

with the KDHE schedule submitted to

EPA, dated May 2, 1986.’’ These

analyses were to address all surface

waters that the State did not designate

for primary contact recreational use.

The schedule of planned use

attainability analyses submitted by

KDHE and accepted by EPA provided

for completion of this task by 1991.

Kansas has performed a number of use

attainability analyses since the adoption

41222 Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules

of the 1994 Water Quality Standards. As

part of its 1998 approval action, EPA

approved over 300 revised use

designations as a result of those use

attainability analyses that were

submitted. However, Kansas did not

include supporting use attainability

analyses for all the surface waters that

the State did not designate for primary

contact recreation. EPA therefore

disapproved those use designations as

being inconsistent with 40 CFR

131.10(g).

3. EPA Proposal To Promulgate Federal

Designated Uses for Specific Stream

Segments and Lakes

Subsequently, in 1999, Kansas

adopted, and submitted to EPA, use

designations consistent with the CWA

and EPA’s implementing regulations for

two streams and 14 lakes for which EPA

had previously disapproved use

designations. On January 19, 2000, EPA

approved these revised use

designations. Kansas also identified in

its 1999 submittal, and EPA approved

on January 19, 2000, the deletion of

seven water bodies due to errors in their

original identification. EPA also

identified, in its January 2000 letter, one

stream segment in Kansas that is located

totally within Indian country, over

which Kansas has not demonstrated

jurisdiction for CWA purposes. In

preparing today’s proposed rulemaking,

EPA also identified four waterbodies the

Agency inadvertently counted twice in

its 1998 disapproval action.

Accordingly, in today’s action, EPA is

proposing to promulgate primary

contact use designations for 1,456

stream segments and lakes and the

State’s expected aquatic life use

designation for one stream segment.

When proposing replacement Federal

water quality standards, EPA must

follow the same rebuttable presumption

approach that applies under the

regulation to State decision-making (40

CFR 131.22). EPA does not believe it

would be appropriate to alter the

current approach to establishing use

designations under 40 CFR part 131

merely because the forum for decisionmaking has changed from the State to

the Federal level. Attaining the goals

articulated by Congress is no less

important when EPA, as opposed to a

State, is making use designation

determinations. Moreover, EPA believes

that failure to apply the rebuttable

presumption in the Federal context

could undermine how that presumption

currently applies to State decisionmaking under the Federal regulations. If

the presumption did not apply equally

in the State and Federal decisionmaking process, a State could effectively

shift the burden of demonstrating

attainability simply by failing to

adequately justify its use designation

and thereby triggering a Federal

rulemaking proceeding.

EPA’s approach in this proposed

rulemaking does not undermine the

State’s primary role in designating uses

for waters in Kansas. If, prior to EPA

finalizing this rule, the State undertakes

a sound analysis of use attainability for

the waters subject to this proposal that

takes into account appropriate

biological, chemical and physical

factors, and concludes that the CWA

section 101(a) goal uses are not

attainable for these waters, EPA would

approve the State’s action and would

not promulgate CWA section 101(a) goal

use designations for those waters. EPA

is soliciting public comment and

information on the attainability of the

proposed Federal uses for the water

bodies listed in proposed 40 CFR 131.34

(g) and (h). EPA also encourages the

State to continue evaluating the

appropriate use designations for these

waters. The State of Kansas has

performed a number of use attainability

analyses (UAAs) since the adoption of

the 1994 Water Quality Standards. As

part of the 1998 approval action, EPA

approved over 300 revised use

designations as a result of those UAAs

submitted to EPA. As part of the State’s

commitment to review uses, Kansas is

updating and standardizing the

protocols for performing UAAs through

a public process. Four public forums

were held by the State to present the

revised UAA protocols to the public.

Improvements to the State’s methods of

performing use attainability analyses

also implements recommendations

made by the Kansas Special

Commission of Water Quality

Standards. Kansas expects to complete

this process in the Summer of 2000.

EPA will review any future UAAs

submitted by the State with the same

level of rigor as it has reviewed previous

UAAs submitted by the State. EPA’s

proposal of designated uses based on

the rebuttable presumption does not

affect the substance of EPA’s review of

State UAAs. If further data indicates

that this presumption is not appropriate

for particular water bodies, EPA’s final

rule will be revised accordingly. In

particular, if EPA determines, based on

the record, that any of Kansas’

designations are justified, there will be

no need for Federally promulgated use

designations for those particular water

bodies. EPA believes that this approach

is reasonable because it is consistent

with the goals in section 101(a)(2) of the

CWA and the implementing regulations

at 40 CFR part 131.

Kansas’ use classification system

includes a variety of designated uses for

its waters, including ‘‘domestic water

supply,’’ ‘‘agricultural water supply,’’

‘‘special aquatic life,’’ ‘‘expected aquatic

life,’’ ‘‘restricted aquatic life,’’ ‘‘primary

contact recreation,’’ and ‘‘food

procurement.’’ Kansas water quality

standards identify three subcategories of

aquatic life uses for Kansas’ surface

waters: Special aquatic life use waters,

expected aquatic life use waters, and

restricted aquatic life use waters. The

Kansas water quality standards define

‘‘expected aquatic life use waters’’ as

‘‘surface waters containing habitat types

and indigenous biota commonly found

or expected in the State.’’ Further, the

Kansas Surface Water Register includes

the expected aquatic life use designation

for the majority of surface waters in the

State. EPA’s approach in proposing

designated uses for 1,457 of the water

bodies is to select uses from Kansas’

system that correspond to CWA section

101(a) goal uses. This approach meets

the requirements of the CWA while

deferring to the State’s approach for

defining 101(a) goal uses.

a. Expected Aquatic Life

EPA is proposing to promulgate an

aquatic life use designation for one

stream segment, Whiskey Creek, that the

State designated for a restricted aquatic

life use in 1994 without a supporting

UAA. Subsequently, the State submitted

a UAA documenting its designation

decision for Whiskey Creek on

December 23, 1997. The basis for this

designation was the State’s

determination that poor water quality,

associated with the discharge from a

wastewater treatment facility, limited

the attainment of an expected aquatic

life use. The State’s determination was

not consistent with Federal regulations

at 40 CFR 131.10, which require that at

least one of six reasons be met to justify

uses less than CWA section 101(a) uses

or downgrades in designated uses. The

reason supplied by Kansas was not one

of the six possible bases specified in the

regulation. Therefore, EPA disapproved

Kansas’ use designation for Whiskey

Creek in 1998.

Because the State assigns the expected

aquatic life use category to a majority of

its surface waters, and there is no

information to indicate that Whiskey

Creek contains other than common

habitat types and indigenous biota, EPA

believes that an expected aquatic life

use designation is appropriate for

aquatic life in Whiskey Creek.

Therefore, EPA proposes to designate

Whiskey Creek for expected aquatic life.

Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules 41223

This water is identified in proposed

131.34 (g).

b. Primary Contact Recreation

EPA is proposing to promulgate

primary contact recreation use

designations for 1,456 waters in Kansas.

In its 1998 action, EPA disapproved the

absence of a primary contact recreation

use designation for 1,484 water bodies.

Of these waters, EPA disapproved nine

water bodies’ use designations because

of inadequate use attainability analyses.

For the remainder, which under Kansas’

water quality standards received default

protection for secondary contact

recreational use, see K.A.R. 28–16–

28d(c)(1), the State provided no

documentation regarding the absence of

a primary contact recreation use.

Therefore, EPA proposes to promulgate

primary contact recreation use

designations for 1,456 waters in Kansas.

These waters are identified in proposed

40 CFR 131.34(h).

The designation of primary contact

recreation uses in this proposed rule is

not intended to apply to waters within

Indian country. The 1999 Kansas

Surface Water Register includes some

stream segments that may be located

wholly or partly in Indian country. EPA

approval of designated uses for waters

in Kansas has never been intended to

apply to any waters located within

Indian country because EPA has not

analyzed or approved the State’s

authority to adopt water quality

standards for waters in Indian country.

In its January 19, 2000, letter, EPA

recommended that the State clarify this

matter by amending the Kansas Surface

Water Register to specify that the State’s

water quality standards do not apply to

any portions of waters located in Indian

country. EPA is working with Tribes in

Region VII to identify those Tribes that

may consider seeking authorization to

administer the water quality standards

program under the CWA. That effort is

part of a national effort to ensure there

are water quality standards for Indian

Country waters.

4. Request for Comment and Data

EPA believes the proposed designated

uses in today’s rule are appropriate

considering the requirements of the

CWA and EPA’s implementing

regulations and the absence of data and

information supporting the State’s

designation of less stringent uses. EPA

solicits any additional data and

information that may further support or

refute the attainability of today’s

proposed designated uses. The Agency

will evaluate any data and information

submitted to EPA by the close of the

public comment period with regard to

designating uses for these 1,457 stream

segments and lakes. After full

consideration of such information, EPA

will make a final decision whether the

designated uses in today’s proposal are

appropriate. To assist commenters, the

following paragraphs provide guidance

on the type of information EPA

considers to be most important.

EPA is seeking information that

would assist in determining for each of

the waters identified in proposed 40

CFR 131.34(g) and (h) whether the

proposed designated uses are currently

being attained or have been attained

since November 28, 1975; whether

natural conditions or features or humancaused conditions prevent the

attainment of these uses and whether

these conditions can or cannot be

remedied or would cause more

environmental damage to correct than to

leave in place; and whether controls

more stringent than those required by

sections 301(b) and 306 of the CWA

would be needed to attain the uses, and,

if imposed, whether they would result

in substantial and widespread social

and economic impact to the community.

A general discussion of the types of

data/information requested by the

Agency follows.

Ambient Monitoring Information: (1)

Any in-stream data for any of the stream

segments listed in 40 CFR 131.34 (g) and

(h) reflecting either natural conditions

(e.g., in-stream flow data or other data

relating to stream hydrology) or

irretrievable human-caused conditions

that cannot be remedied and that

prevent the uses or water quality criteria

from being attained; (2) any available instream biological data; (3) any chemical

and biological monitoring data that

verify improvements to water quality as

a result of treatment plant/facility

upgrades and/or expansions; and (4) any

in-stream data reflecting nonpoint

sources of pollution or best management

practices that have been implemented

for nonpoint source control.

Current and Historical Effluent Data:

(1) Any data and information relating to

mass loadings from point source

discharges of pollutants such as BOD,

NH3 -N, chlorine, metals (e.g., arsenic,

cadmium, chromium, copper, lead,

mercury, nickel, silver, zinc), other

toxics (e.g., volatile organic chemicals

such as benzene or toluene, acid

extractables such as pentachlorophenol,

base neutrals such as anthracene,

fluorine or pyrene, and pesticides such

as aldrin, lindane, DDT, dieldrin, endrin

and toxaphene); (2) data and

information related to facility or

treatment plant effluent quality; and (3)

any information related to releases of

pollutants from other sources such as

landfills, transportation facilities,

construction sites, agriculture/

silviculture, incinerators, and

contaminated sediments.

Water Quality Modeling Information:

(1) Any data or information on

analytical models that can be used to

evaluate or predict stream quality, flow,

morphology; (2) any physical, biological

or chemical characteristics relating to

designated uses; and (3) the results of

any such models that can be used to

evaluate the attainment of designated

uses.

Economic Data: any information

relating to costs and benefits associated

with or incurred as a result of facility or

treatment plant expansions or upgrades.

This information includes: (1)

Qualitative descriptions or quantitative

estimates of any costs and benefits

associated with facility or treatment

plant expansions or upgrades, or

associated with facilities or treatment

plants meeting limits; (2) any

information on costs to households in

the community with facility or

treatment plant expansions or upgrades,

whether through an increase in user

fees, an increase in taxes, or a

combination of both; (3) descriptions of

the geographical area affected; (4) any

changes in median household income,

employment, and overall net debt as a

percent of full market value of taxable

property; and (5) any effects of changes

in tax revenues if the private-sector

entity were to go out of business,

including changes in income to the

community if workers lose their jobs,

and effects on other businesses both

directly and indirectly influenced by the

continued operation of the private

sector entity.

B. Stream Design Flow

1. Background

The 1985 Kansas water quality

standards at K.A.R. 28–16–28c(c)(1)

specified conditions for the application

of numeric water quality criteria to State

waters, including stream flows below

which numeric criteria did not apply

(i.e., the 7Q10 or 1 cubic foot per second

(cfs)). The 1985 provisions at K.A.R. 28–

16–28c(b), describing the allocation of

dilution for discharges to classified

streams based on the use of mixing

zones, did not specify a stream design

flow. Revisions to the 1985 Kansas

water quality standards at K.A.R. 28–

16–28c(c)(1) in 1994 introduced a

stream design flow of an ‘‘assumed

7Q10’’ in addition to a ‘‘measured

7Q10,’’ defining the stream flow below

which numeric criteria do not apply.

Under the 1994 revisions, an ‘‘assumed

7Q10’’ of either 1 cfs or 0.1 cfs

41224 Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules

(depending upon the particular aquatic

life use designation of that stream

segment) would serve as the low flow

cut-off if the ‘‘measured 7Q10’’ was

below one of those values. Exceptional

State waters and special aquatic life use

waters are afforded 0.1 cfs for assumed

dilution, whereas expected aquatic life

use waters and restricted aquatic life use

waters are afforded 1 cfs for assumed

dilution. In its 1994 revisions to the

mixing zone provisions at K.A.R. 28–

16–28c(b), the State also explicitly

included the concept of either the

‘‘measured 7Q10’’ or the ‘‘assumed

7Q10’’ flow in its calculation of the

mixing zone cross-sectional area and,

therefore, the dilution available to meet

the applicable criteria. In disapproving

these provisions in 1998, EPA pointed

out that implementation of this

provision could authorize water quality

based effluent limits (WQBELs) that

would cause exceedences of numeric

water quality criteria beyond the mixing

zone and would fail to protect the

designated uses of the water body.

For example, under K.A.R. 28–16–

28e(c)(2)(F), the State applies its acute

and chronic numeric water quality

criteria for protecting aquatic life

outside the zone of initial dilution and

beyond the mixing zone, respectively. In

this manner, toxicity within the waters

of the State is prevented. Under other

provisions at K.A.R. 28–16–28e(c)(4)

and (7), State standards specify numeric

criteria for protecting food procurement

and recreational uses, respectively,

beyond the mixing zone. K.A.R. 28–16–

28c(b) specifies the dimension of the

allowed mixing zone based on the

designated use of the water body and

the ratio of the receiving stream 7Q10

flow to the discharge design flow. In the

calculation of the specific mixing zone

cross-sectional area or volumetric flow,

the State standards regulation provides

for the use of either the 7Q10 flow or an

assumed flow.

Reliance on an ‘‘assumed flow’’

provides for dilution which does not

exist and will result in the criteria being

exceeded more often than once in three

years as specified in the State’s numeric

criteria for chronic protection. The 1999

State standards at K.A.R. 28–16–28b(lll)

implement the acute aquatic life criteria

by defining the size or volume of the

allowed zone of initial dilution in terms

of the allowed mixing zone (i.e., no

more than 10% of the mixing zone).

Calculating a mixing zone crosssectional area that allows for an

assumed flow is not scientifically

defensible because it relies on flow that,

at times, does not exist. EPA

recommends a 1B3 or 1Q10 design flow

for acute aquatic life protection, and

harmonic mean flow for human health

protection including recreational uses.

EPA believes that the State’s use of a

7Q10 design flow for implementation of

human health is protective of the

corresponding designated uses.

Therefore, EPA is only proposing to

promulgate design flows for the

protection of acute and chronic aquatic

life.

In August 1999, KDHE submitted

water quality standards revisions for

EPA review and approval that included

revisions to K.A.R. 28–16–28c(b)(2)(D)

and (c)(1). These new or revised

provisions were relocated to K.A.R. 28–

16–28c(b)(7) and (b)(8), subsection (A)

through (D) without being substantially

revised. The provisions disapproved by

EPA in its 1998 action regarding

assumed low flow remained. In EPA’s

January 19, 2000, approval/disapproval

letter, EPA informed the State that the

revised provisions at K.A.R. 28–16–

28c(b)(7) and (b)(8) remain disapproved

consistent with EPA’s 1998 disapproval

decision.

2. EPA Review of Kansas’ Assumed

Flow Provision

Kansas’ water quality criteria are

derived from EPA’s recommended

304(a) water quality criteria which are

designed around specific assumptions

regarding magnitude of exposure,

duration of exposure and the frequency

these parameters may be exceeded and

still protect the designated use. These

parameters are based on the

toxicological studies supporting the

criteria. These toxicological

assumptions are matched to

biologically-based stream design flows

to ensure that the probabilities of

occurrence for both pollutant

concentrations and stream flow are

protective of aquatic life. Simply put,

the water quality criteria relied upon to

protect designated uses are inseparable

from the stream design flow

assumptions through which they are

implemented. EPA guidance in the 1994

Water Quality Standards Handbook and

the 1991 Technical Support Document

for Water Quality-based Toxics Control

identify the stream flows that match the

aquatic life criterion continuous

concentration (CCC, or chronic criteria)

and the criterion maximum

concentration (CMC, or acute criteria) as

the biologically-based 4B3 and 1B3,

respectively. These statistically derived

flows match the averaging periods and

recurrence frequency specified in the

State’s water quality criteria. Although

EPA recommends the use of

biologically-based flows in

implementing water quality criteria,

there are alternative approaches. Most

States routinely rely on hydrologicallybased flows derived using the Log

Pearson 3 method generated by the U.S.

Geological Survey, to implement water

quality criteria. EPA guidance evaluated

the compatibility of using ‘‘extreme

value statistic flows’’ (e.g., 7Q10) for the

implementation of water quality criteria

for the protection of aquatic life

(Technical Guidance Manual for

Performing Waste Load Allocations,

Book VI, Design Conditions: Chapter 1—

Stream Design Flow for Steady-state

Modeling. August 1986). EPA

determined that, for most waters and in

most instances, the use of 7Q10 and

1Q10 hydrologically-based stream

design flows for the implementation of

chronic and acute water quality criteria,

respectively, provides a level of

protection commensurate with EPA’s

recommended biologically-based flows.

That is, 7Q10 equates to the 4B3 and

1Q10 equates to the 1B3. States may

select other design flows based on a

demonstration that such alternative

flows are protective of the specified

designated uses. Also, States are

encouraged to use dynamic modeling as

a scientifically defensible alternative to

extreme flow statistics.

Many Kansas streams possess 7Q10

flows of zero, particularly western

streams that are already stressed by

excessive surface and ground water

withdrawals. Small, low flow headwater

streams that serve as critical habitat for

many threatened and endangered

aquatic species may receive toxic

loadings of pollutants as a result of the

implementation of this provision

because discharge limits would be based

on flow that is not there. K.A.R. 28–16–

28d(b)(1) applied water quality

standards to those streams with mean

summer base flows exceeding 0.1 cfs

and those with less flow but with

adequate pooling that serve as refuge for

aquatic life during intermittent flow.

Base flow is specifically defined in State

standards to include sources of flow

other than precipitation or ground water

(e.g., effluent discharge and irrigation

return flow). Many streams classified for

designated uses under this provision

(i.e., streams with mean summer base

flows greater than 0.1 cfs) nevertheless

have 7Q10 flows of less than 1 or 0.1

cfs. In such instances, Kansas’ standards

allow a classified stream to receive

discharges that rely on dilution to

comply with State standards, even

though the dilution does not exist. This

will result in ambient pollutant

concentration exceeding the criteria

value more often than once every three

years as specified in the State’s numeric

aquatic life criteria.

Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules 41225

EPA expects that the scientific

defensibility of alternate flows would be

dependent upon pollutant-specific or

site-specific circumstances such as

watershed size and characteristic

hydrography. EPA believes that Kansas’

implementation of these assumed flows

is not scientifically defensible or

protective of the State’s designated

aquatic life use, as required by the Clean

Water Act and EPA’s implementing

regulations.

KDHE has not provided any scientific

rationale for the use of assumed flows

or provided any data suggesting that this

provision will sufficiently protect the

designated aquatic life uses. EPA’s

regulations at 40 CFR 131.21(a)(2)

require that new or revised standards be

accompanied by supporting analyses.

KDHE noted in its ‘‘Response to

Comments Concerning Proposed

K.A.R.’’s 28–16–28 b through f’’ (June

23, 1994) that default low flows are

employed in other States, that they are

necessary because of the paucity of flow

data in small watersheds, and that some

form of this provision has been

employed by Kansas for twenty years.

Although these are valid points, they are

not compelling reasons to approve State

provisions that do not ensure the

protection of the designated uses of

Kansas’ surface waters. As EPA’s 1994

Water Quality Standards Handbook

(EPA–823–B–94–005a) specifically

states, ‘‘[The fact that] many streams

within a state have no flow at 7Q10 is

not adequate justification for

designating alternative flows.’’ Because

Kansas failed to adequately justify its

alternative stream flow provisions, EPA,

in its 1998 action, disapproved the

standards provisions under K.A.R. 28–

16–28c(b)(2)(D) and (c)(1) that reference

assumed flows.

The State, in a February 26, 1999,

letter to EPA and in its draft 1999

implementation procedures, noted that

the primary purpose of the alternate

flow approach is to provide economic

relief for ‘‘small communities [that] will

face costly upgrades or construction of

completely new treatment systems if

permit limits are made more stringent.’’

KDHE further stated in the letter to EPA

that ‘‘[T]he environmental benefit is

small compared to the large and

widespread costs associated with the

removal of the minimum default flows.’’

Although these potential impacts are of

concern, the CWA and EPA’s

implementing regulations do not allow

considerations of costs and benefits in

establishing water quality criteria

(design flows are a component of the

criteria). Under Federal regulations,

economic impacts associated with

standards should be taken into account

when assessing the attainability of

designated uses and granting temporary

variances to water quality standards. 40

CFR 131.10(g). It is permissible for the

State to grant individual variances or to

downgrade a designated use for a

specific water body relying on economic

data, but relying on dilution that is not

available to violate the State’s numeric

criteria is not scientifically defensible.

In section V, EPA discusses its analysis

of the potential economic impacts

associated with today’s proposed

standards.

3. EPA Proposal To Promulgate Stream

Design Flows

In today’s action, EPA is proposing

the 7Q10 or 4B3 stream design flows for

the implementation of chronic aquatic

life criteria in Kansas. Additionally,

EPA is proposing the 1Q10 or 1B3

design flow for the implementation of

acute aquatic life criteria in Kansas.

Kansas may submit to EPA alternate low

flows for implementing criteria. Such

alternative flows must be scientifically

defensible, protective of the designated

use, and approved by EPA before they

can be used by the State.

4. Request for Comment and Data

EPA solicits any additional data and

information that may further support or

refute the attainability of the changes

being proposed today. The Agency will

evaluate any data and information

submitted to EPA by the close of the

public comment period. EPA will

consider all available information and

make a final decision on the

appropriateness of today’s proposed

changes.

C. Effluent-Created Habitat

1. Background

Another regulation submitted to EPA

by Kansas in 1994, K.A.R. 28–16–

28c(c)(3), addressed those streams

where designated uses are not attainable

because of inadequate stream flow.

Under the State’s provision, if

continuous flow in a stream is sustained

primarily through the discharge of

treated effluent, and all designated uses

are otherwise unattainable due to low or

nonexisting flow, then the discharger

shall not be required to provide

treatment beyond that required by

technology-based effluent limitations

imposed under Federal law. That

exemption would not apply, however, if

the resulting effluent would result in

violations of the State’s narrative water

quality criteria or in an impairment of

any of the existing or designated uses of

a downstream classified surface water

segment. In other words, this provision

exempts dischargers from having to

meet water quality-based effluent

limitations derived from numeric water

quality criteria adopted to protect the

designated uses.

2. EPA Review of Kansas’ EffluentCreated Habitat Provision

Implementation of K.A.R. 28–16–

28c(c)(3) would result in State NPDES

permits that cause or contribute to

excursions above State water quality

standards (i.e., numeric criteria)

prohibited by 40 CFR 122.44(d).

Further, this reduced level of protection

achieved through the NPDES permit is

in effect a lowering of the designated

use based on the State’s determination

that stream flow was inadequate. Not

only has the State failed to submit a

UAA to justify the implicit use

downgrade, but, if Kansas had done so,

such an approach would clearly be

inconsistent with 40 CFR 131.10(g)(2).

EPA’s regulation specifically prohibits

the removal or down-grading of a

designated use based on inadequate

flow where ‘‘* * * these conditions

may be compensated for by the

discharge of sufficient volume of

effluent discharges * * *to enable uses

to be met.’’ 40 CFR 131.10(g)(2).

EPA previously informed the State of

the basis for its position in letters dated

May 13, 1993, to Dr. Hammerschmidt,

Deputy Director, Division of

Environment, KDHE, and May 24, 1994,

to Mark Bradbury, District

Environmental Administrator, KDHE,

which were entered into the record at

the public hearings held by KDHE

during its standards adoption. EPA

disapproved this provision in its 1998

action. In its disapproval letter to the

State, EPA stated that this deficiency

could be remedied by deleting the

provision or by revising K.A.R. 28–16–

28c(c)(3) to require that, prior to a

removal of a designated use, a showing

be made as to whether attaining the

designated use is not feasible consistent

with the provisions at 40 CFR 131.10(g).

In 1999, the State of Kansas adopted

subsequent revisions to its water quality

standards, including revisions to K.A.R.

28–16–28c(c)(3). Those revisions

recognize the need for the State to

conduct a use attainability analysis to

support any downgrade in use and

acknowledge that any new or revised

use would need to be adopted as part of

the State’s water quality standards.

However, in oral communications

with EPA staff, KDHE staff informed

EPA that the 1999 revisions also

authorize NPDES permit limitations to

be based on the use attainability

analysis even before the corresponding

revised use designations are adopted by

41226 Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules

the State into their water quality

standards. That is inconsistent with the

current EPA regulations. In effect,

Kansas is removing a designated use

upon completion of a UAA but prior to

following the public process for water

quality standards revisions. 40 CFR

131.20(b). Furthermore, under recently

promulgated regulations at 65 FR 24641

(April 27, 2000), revisions to State water

quality standards will not be effective

for the purposes of the CWA until

approved by EPA. Therefore, a use

attainability analysis contemplated

under the provisions of the 1999

revisions cannot serve as a basis for

NPDES permit limitations until the

State adopts the corresponding use

designation revision, submits it to EPA,

and obtains EPA approval. K.A.R. 28–

16–28c(c)(3), in effect, would allow

permitting authorities to calculate

limitations based on the results of a use

attainability analysis irrespective of the

outlined process. For that reason, the

1999 Kansas revisions are inconsistent

with EPA’s implementing regulations

and do not address the deficiencies

identified in EPAs 1998 disapproval

letter with respect to the State’s earlier

version of that section. Therefore, the

1999 Kansas revisions to this provision

do not eliminate the need for a Federal

promulgation.

3. Ensuring Discharges to EffluentCreated Habitat Waters Protect the

Designated Use

EPA is proposing to promulgate a

provision requiring that designated uses

at K.A.R. 28–16–28d and K.A.R. 28–16–

28e for stream segments for which

continuous flow is sustained primarily

through the discharge of treated effluent

must be protected (irrespective of the

development of a use attainability

analysis that demonstrates that a

different use may be appropriate) until

EPA approves a revision to the

applicable use designation.

4. Request for Comment and Data

EPA solicits any additional data and

information that may further support or

refute the need for the changes being

proposed today. The Agency will

evaluate any data and information

submitted to EPA by the close of the

public comment period. After full

consideration of such information, EPA

will make a final decision on the

appropriateness of the changes in

today’s proposal.

D. Procedures for Implementing the

State’s Antidegradation Policy

1. Background

In compliance with Federal

regulations at 40 CFR 131.12(a), the

State identified its methods for

implementing the State’s

antidegradation policy and submitted

these methods to EPA as part of the

Kansas Surface Water Quality

Implementation Procedures (October 18,

1994) on October 31, 1994. The Kansas

Surface Water Quality Implementation

Procedures (the Procedures) contained

procedures the State uses to implement

its antidegradation policy and develop

water quality-based effluent limitations

and conditions for NPDES permits. The

portion of the Procedures addressing

implementation of the State’s

antidegradation policy only addressed

point sources of pollution. The State’s

Procedures were silent on implementing

the antidegradation requirements of

K.A.R. 28–16–28c(a)(2), in the context of

determining whether to allow a

lowering of surface water quality by

point sources of pollution where

nonpoint sources also contribute the

pollutant of concern to that body of

water. On August 10, 1999, the State

submitted revised Kansas

Implementation Procedures: Surface

Water (June 1, 1999) to EPA for review

and approval. The citation for the State

antidegradation regulation changed

from K.A.R. 28–16–12c(a)(2) to K.A.R.

28–16–28c(a)(1)(B) in the 1999

revisions.

2. EPA’s Review of Kansas’

Antidegradation Implementation

Procedures

As part of its review of the 1994

submission of new or revised water

quality standards from the State, EPA

reviewed the portion of Kansas Surface

Water Quality Implementation

Procedures (October 18, 1994)

addressing antidegradation, section 3,

and found that the procedures did not

fully address implementation of Kansas’

antidegradation policy consistent with

Federal regulations at 40 CFR 131.12(a).

As discussed in section III. F., however,

the State addressed all but one of the

deficiencies in its 1999 submission, and

EPA approved them in January 2000.

Although revised in 1999, the State’s

antidegradation implementation

procedures still did not identify how

Kansas would implement the

requirement in K.A.R. 28–16–

28c(a)(1)(B) that all cost-effective and

reasonable best management practices

for nonpoint sources of pollution shall

be achieved in instances when the

KDHE allows a lowering of water

quality by point sources. Accordingly,

EPA’s February 1998 disapproval

remains in effect.

3. EPA Proposal To Promulgate

Antidegradation Implementation

Provisions for Kansas

Because of this continuing deficiency

in Kansas’ antidegradation

implementation procedures, EPA is

proposing to identify implementation

procedures for use when applying

K.A.R. 28–16–28c(a)(1)(B) to determine

whether to allow a lowering of surface

waters quality by point sources of

pollution where nonpoint sources also

contribute the pollutant of concern to

that body of water. The proposed

implementation procedures are

described next.

Consistent with Federal regulations,

Kansas’ antidegradation policy at K.A.R.

28–16–28c(a)(1)(B) requires that, before

allowing degradation of water quality in

high quality waters from a point source,

the highest statutory and regulatory

requirements for all point sources, and

all cost effective and reasonable BMPs

for controlling nonpoint sources, are

achieved. This requirement ensures

that, before additional increments of

water quality are used by point sources,

nonpoint sources currently introducing

the same pollutants into the water body

are taking all reasonable steps required

by State law to minimize the

introduction of those pollutants. The

implementation procedures proposed

today are intended to facilitate the

application of this requirement in

Kansas’ antidegradation regulation.

These proposed procedures are based on

guidance issued by EPA in 1994 entitled

Interpretation of Federal

Antidegradation Regulatory

Requirement, from Tudor T. Davies,

dated February 22, 1994. They consist of

three steps to be undertaken when

applying K.A.R. 28–16–28c(a)(1)(B) to

determine whether to allow a lowering

of surface water quality by point sources

of pollution where non-pont sources

also contribute the pollutant of concern.

First, Kansas would need to identify

significant sources (or categories) of

nonpoint pollution that may impact a

high quality water body by releasing the

pollutants of concern. Second, Kansas

would need to identify reasonable and

cost-effective BMPs for each of these

significant nonpoint sources or source

categories. Third, Kansas would need to

determine that significant nonpoint

sources in those nonpoint source

categories will implement the

appropriate BMPs. In addition, EPA

recommends conducting these analyses

prospectively, on a watershed basis, to

Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules 41227

facilitate antidegradation reviews of

individual activities.

With respect to the first step,

significant nonpoint source contributors

can be identified through an analysis of

all nonpoint source contributors in the

area, or by an analysis of all nonpoint

source contributors whose proximity to

the water body, water body segment, or

tributaries makes them ‘‘significant’’ in

terms of potential water quality impact.

Other factors such as the degree of

uncertainty concerning cause-effect

relationships can also be considered.

Consistent with EPA’s interpretation of

its regulations, Kansas need only

identify nonpoint source contributors

for which the State has established

requirements to implement control

programs, but Kansas may also choose

to identify other significant nonpoint

source contributors that are not subject

to such programs.

With respect to the second step of this

implementation procedure, Kansas need

only identify those cost-effective and

reasonable BMPs or other nonpoint

source pollution reduction measures

that are part of its nonpoint source

programs, including any developed

under section 319 of the CWA, and that

are required to be implemented under

State law. Of course, the State is also

free to identify cost-effective and

reasonable BMPs that are not required

by State law.

With respect to the third step, the

State need only determine that the

BMPs will be implemented. Such a

determination can rely on Kansas

regulations, local ordinances,

performance bonds, contracts, cost share

agreements and memorandums of

understanding, as well as voluntary

programs under certain circumstances,

e.g., an active nonpoint source program

covering a watershed or area of concern.

Under this proposed regulation, the

implementation procedures would

apply to any determination under

K.A.R. 28–16–28c(a)(1)(B) to allow a

lowering of water quality from a point

source where nonpoint sources are also

contributing the pollutant of concern to

the body of water. The State is also

encouraged to apply or adapt the EPA’s

1994 guidance to other activities that

State law requires to comply with Tier

2 of the State’s antidegradation

requirements, including new or

significantly expanded nonpoint

sources.

To comply with the requirements of

today’s proposal, EPA would expect that

permit fact sheets or statements of basis

for facilities permitted under the

National Pollutant Discharge

Elimination System (NPDES) program

describe compliance with

antidegradation requirements through

the application of the proposed

implementation procedures. EPA may

object to any permit that does not meet

the requirements of the Clean Water

Act. Where there is no discussion of

antidegradation in the NPDES permit

fact sheet, EPA may be unable to

determine that the permit conditions

derive from and comply with the State

standards and with the requirements of

the CWA.

4. Request for Comment and Data

EPA solicits comment on the

antidegradation implementation

procedures it is proposing. EPA also

requests comments on any other

procedures that could be used to

implement the Kansas requirements at

K.A.R. 28–16–28c(a)(1)(B). EPA also

requests comment on whether it is

necessary to promulgate a regulation in

order to establish these implementation

procedures for Kansas. The Agency will

evaluate any comments, data and

information submitted to EPA by the

close of the public comment period.

After full consideration of such

comments, data, and information, EPA

will make a final decision on the

appropriateness of today’s proposed

changes and EPA’s antidegradation

implementation procedures with respect

to the relationship between point and

nonpoint sources.

V. What Federal Water Quality

Standards Is EPA Proposing Under

Section 303(c)(4)(B)?

A. Legal Basis

CWA section 303(c) specifies that

adoption of water quality standards is

primarily the responsibility of the

States. However, section 303(c) also

describes a role for EPA overseeing State

actions to ensure compliance with CWA

requirements. If EPA’s review of the

State’s standards finds flaws or

omissions, then the CWA authorizes

EPA to promulgate replacement Federal

standards to correct the deficiencies if

the State or authorized Tribes fail to do

so. See section 303(c)(4).

Section 303(c)(4) of the CWA provides

two bases for promulgation of Federal

water quality standards. The first basis,

in 303(c)(4)(A), applies when a State

submits new or revised standards that

EPA determines are not consistent with

the applicable requirements of the CWA

and EPA’s implementing regulations. If

the State does not amend its rules

within 90 days of EPA’s disapproval to

be consistent with the CWA and EPA’s

implementing regulations, EPA must

promptly propose appropriate Federal

water quality standards for that State.

The second basis for EPA’s action is

303(c)(4) (B), which provides that EPA

shall promptly initiate promulgation

‘‘* * * in any case where the

Administrator determines that a new or

revised standard is necessary to meet

the requirements of this Act.’’ The

authority to make a finding under

section 303(c)(4)(B) of the CWA and to

propose and promulgate Federal

regulations correcting such State water

quality standards rests solely with the

Administrator.

B. Water Quality Criteria for AlphaEndosulfan and Beta-Endosulfan

1. Background

Under section 303(c)(2)(B) of the

CWA, States must adopt numeric water

quality criteria for toxic pollutants listed

under EPA section 307(a)(1) for which

EPA has published section 304(a)

criteria, if the presence of the toxic

pollutant in the State’s waters is

reasonably expected to interfere with

the protection of the waters’ designated

uses. On December 22, 1992, EPA

promulgated the National Toxics Rule

(NTR), specifying the chemical-specific,

numeric water quality criteria for

priority toxic pollutants necessary to

bring all States into compliance with the

requirements of section 303(c)(2)(B) of

the CWA. At that time, Kansas had

failed to revise its water quality

standards to meet the requirements of

section 303(c)(2)(B) of the CWA.

Therefore, in the NTR, EPA

promulgated numeric water quality

criteria for a number of toxic pollutants

for the protection of aquatic life and

human health in Kansas.

2. Administrator’s Findings Regarding

Alpha-Endosulfan and Beta-Endosulfan

The Administrator has determined

that new or revised water quality

standards for alpha- and betaendosulfan are necessary to protect

human health in Kansas. The

Administrator bases this determination

on the fact that the State has failed to

adopt standards required by section

303(c)(2)(B) despite information that

alpha- and beta-endosulfan may

reasonably be expected to interfere with

drinking water designated uses. In

enacting section 303(c)(2)(B), Congress

indicated the need for prompt adoption

and implementation of water quality

standards for toxic pollutants if the

presence of the toxic pollutants in the

State’s waters is reasonably expected to

interfere with the protection of the

waters’ designated uses. Therefore, a

State’s failure to meet this fundamental

section 303(c)(2)(B) requirement of

adopting appropriate standards

41228 Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules

constitutes a failure ‘‘to meet the

requirements of the Act.’’ Under this

proposed rulemaking, the State of

Kansas retains the ability to adopt water

quality criteria for these pollutants and

correct this deficiency.

3. Request for Comment and Data

EPA solicits any additional data and

information that may further support or

refute the need for numeric water

quality criteria for alpha- and betaendosulfan. The Agency will evaluate

any data and information submitted to

EPA by the close of the public comment

period. After full consideration of such

information, EPA will make a final

decision whether the changes in today’s

proposal are appropriate.

C. Administrator’s Finding Regarding

Privately Owned Surface Waters

1. Background

In its 1998 disapproval letter, EPA

identified certain existing water quality

standards within the K.A.R. relating to

the application of water quality

standards to privately owned surface

waters that EPA had previously

approved, but that appeared to be

inconsistent with the CWA and EPA’s

implementing regulations. The Region

therefore indicated that this issue would

be forwarded to the Administrator for

action consistent with her authority

under CWA section 303(c)(4)(B).

At issue is K.A.R. 28–16–28c(f),

entitled Application of Standards to

Privately-Owned Surface Waters, which

states that the application of water

quality standards to privately owned

water bodies shall be subject to the

provisions of K.S.A. 65–171d. The State

law cited in the regulation provides in

relevant part as follows: If a freshwater

reservoir or farm pond is privately

owned, and where complete ownership

of land bordering the reservoir or pond

is under common private ownership,

such freshwater reservoir or farm pond

shall be exempt from water quality

standards in Kansas except as it relates

to water discharges or seepage from the

reservoir or pond to waters of the State,

either surface water or ground water, or

as it relates to the public health of

persons using the reservoir or pond or

waters therefrom. This is inconsistent

with the CWA and EPA’s implementing

regulations to the extent that it would

potentially exempt from water quality

standards surface water—regardless of

its ownership characteristics—that may

be a water of the United States. Kansas’

exclusion of private waters from

protections under the CWA could also

be a problem in the State’s NPDES

program. Kansas’ failure to apply the

State’s water quality standards to all

surface waters—including private

waters—that are waters of the United

States was specifically identified as a

program deficiency by EPA in an

October 1, 1990, letter from Martha

Steincamp, EPA Regional Counsel, to

David Traster, General Counsel for

KDHE. As a result of discussions

between EPA’s Regional Office and

KDHE, this statutory deficiency was to

have been addressed by legislative

action in the 1991 legislative session,

but no such correction occurred.

The CWA does not recognize

distinctions in ownership in the

application of water quality standards to

waters of the United States. Rather, the

CWA requires that water quality

standards apply to all waters of the

United States, making no distinction

between publicly and privately owned

waters. The Administrator therefore has

determined under section 303(c)(4)(B)

that the identified provisions are

inconsistent with the CWA and EPA’s

implementing regulations. In today’s

Federal Register notice, EPA is

proposing to narrow the exemption for

privately owned surface waters (notably

lakes and wetlands) so that the

exemption would not apply to waters of

the United States. Whether a particular

water is a water of the United States is

a water body-specific determination.

EPA is not aware of any waters of the

United States in Kansas that are

currently exempted from State water

quality standards because of to the

State’s provision; nonetheless, EPA

believes the State’s provision creates a

potential loophole that may preclude

the State from protecting a waterbody

from degradation. Every privately

owned waterbody that is a water of the

United States is entitled to—and indeed

requires—protection under the CWA.

Should the need ever arise to apply

water quality standards to any privately

owned water that is a water of the

United States, the State’s standard for

unclassified waters would apply.

2. Request for Comment and Data

EPA solicits any additional data and

information that may further support or

refute the changes being proposed

today. The Agency will evaluate any

data and information submitted to EPA

by the close of the public comment

period. After full consideration of such

information, EPA will make a final

decision whether the changes in today’s

proposal are appropriate.

VI. Economic Analysis

This proposed rule would have no

direct impact on any entity because the

proposed rule, once finalized, will

simply establish water quality standards

(e.g., ambient water quality criteria)

which by themselves do not impose any

costs. These standards, however, may

serve as a basis for development of

NPDES permit limits. In Kansas, the

State is the NPDES permitting authority

and retains considerable discretion in

implementing standards. Thus, until the

State implements these water quality

standards, there will be no effect on any

entity. Nonetheless, EPA prepared a

preliminary analysis to evaluate

potential costs to NPDES dischargers in

Kansas associated with future State

implementation of EPA’s Federal

standards.

Any NPDES-permitted facility that

discharges to water bodies affected by

the proposed rule or that is subject to

effluent limits for pollutants for which

EPA is proposing to promulgate criteria

could potentially incur costs to comply

with the proposed rule’s provisions. The

types of affected facilities may include

industrial facilities and publically

owned treatment works (POTWs). EPA

did not consider the potential costs for

nonpoint sources, such as agricultural

and forestry-related nonpoint sources,

although EPA recognizes that controls

on these sources may be necessary to

achieve designated uses. Nonpoint

source discharges are technically

difficult to model and evaluate for

costing purposes because they are

intermittent, highly variable, and occur

under different hydrologic or climatic

conditions than continuous discharges

from industrial and municipal facilities,

which are evaluated under critical low

flow or drought conditions. Thus, the

evaluation of nonpoint sources and their

effects on the environment is highly site

specific and data sensitive. In addition,

EPA did not address the potential

monetary benefits of this proposed rule

for Kansas.

A. Identifying Affected Facilities

EPA used available data to identify

the total number of facilities discharging

to Kansas surface waters and the

number that may be affected by the

provisions of today’s proposed rule.

According to EPA’s Permit Compliance

System (PCS), there are 1,253 NPDESpermitted facilities in Kansas. Fiftyseven of the facilities are classified as

major dischargers, and 1,196 are minor

dischargers. The total includes 320

nondischarging animal feedlots and 85

sand and gravel quarries, which are all

classified as minor dischargers.

In determining the number of

facilities potentially affected by the

proposed rule, EPA did not include

non-discharging animal feedlots or sand

and gravel quarries. Because CWA

Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules 41229

section 301(a) prohibits point sources,

including concentrated animal feeding

operations (CAFOs), from discharging to

surface waters without a permit, and

because NPDES permits for CAFOs in

turn prohibit discharges, EPA was not

aware of any CAFO that would be

impacted by EPA’s proposal to upgrade

the water use designation. (The only

CAFOs that would be affected would be

those discharging in violation of CWA

section 301(a) or their permit, and EPA

is not aware of such CAFOs in Kansas.)

Nonetheless, EPA is aware that there

may be facilities that presently are not

subject to NPDES permitting

requirements but that theoretically

could be designated as CAFOs. EPA

therefore requests information or data

on any animal feeding facilities in

Kansas that are discharging to waters for

which EPA proposes to upgrade their

designated uses and that therefore might

be affected by this proposal.

EPA did not consider sand and gravel

quarries because they would not

discharge pollutants of concern in EPA’s

proposed rule. Sand and gravel quarries

likely have permit limits only for total

suspended solids. In addition, some

quarries may have no discharge.

Therefore, the universe of dischargers

that might be affected by EPA’s

proposed rule includes 848 permitted

facilities (57 majors and 791 minors).

To identify facilities potentially

affected by the proposed designated use

change, EPA determined which of the

848 permitted facilities are located on

water bodies with proposed changed

use designations. EPA evaluated 1,485

stream segments and lakes for today’s

proposed rule. However, EPA could not

discern the location of all facilities with

respect to these segments. For water

bodies where EPA today proposes to

upgrade the designated use, EPA solicits

any additional data and information

(e.g., if there are discharges to such

streams; how the discharges are

permitted; concentrations of pollutants

in such discharges, etc.) that may

further support or refute the

attainability of EPA’s proposed changes.

To identify facilities discharging to

waters lacking primary contact

recreation uses, EPA matched water

body data to facility records in EPA’s

Permit Compliance System (PCS) and

Industrial Facilities Database and a

database provided by the State of

Kansas. This effort identified 154

facilities (6 majors and 148 minors) that

discharge to segments affected by the

proposed rule. However, EPA could not

discern the discharge location of over

300 facilities, so it is not known

whether these facilities would be

affected by the proposed rule or not. To

estimate costs, EPA assumed these

facilities to be located on affected water

bodies in the same proportion as

identified facilities.

Of the 1,485 stream segments and

lakes evaluated, one is also lacking an

aquatic life support use (Whiskey

Creek). Using the same procedures, EPA

identified one facility that discharges to

Whiskey Creek.

To identify facilities discharging to

waters affected by the proposed

assumed flow changes, EPA linked PCS

facility data and State-provided facility

data with stream segment information

from EPA’s National Computer Center

Gauge File. EPA identified 116 facilities

(3 majors and 113 minors) on water

bodies with 7Q10 flows less than 1 cfs.

Of these 116 facilities, 69 facilities (2

majors and 67 minors) were located on

streams with zero flow. Thus, EPA

assumed that facilities evaluated for

assumed flow changes would also

account for those facilities impacted by

the effluent created habitat provision of

today’s proposed rule. As such, EPA did

not assess the costs for these two

provisions separately. Note, however,

that flow data were not available for

over half of the facilities. To estimate

costs, EPA assumed that the proportion

of facilities on water bodies with flow

data that had low flows less than 1 cfs

would be the same as the proportion of

facilities on water bodies without flow

data with low flows less than 1 cfs. EPA

requests comment on its assumption

that the assumed flow analysis accounts

for facilities affected by the effluent

created habit provision of today’s

proposal. EPA solicits any additional

data and information on facilities

discharging to waters affected by the

effluent created habitat provision that

may further support or refute this

approach.

EPA found no facilities in PCS in

Kansas with effluent limits for alphaendosulfan or beta-endosulfan.

Although this does not necessarily mean

that there would be no impact from

proposed water quality criteria for these

pollutants (i.e., facilities may have these

pollutants in their effluent and may be

subject to effluent limits under the

proposed criteria), EPA does not have

data with which to evaluate effluent

concentrations. EPA requests that

persons with data or information on the

discharge of alpha- or beta-endosulfan

to surface waters in Kansas to provide

it to the Agency for evaluation.

With respect to EPA’s proposal to

apply the States’ water quality standards

to privately owned surface waters that

are waters of the United States, EPA was

unable to evaluate the economic impact

of that proposal for several reasons. EPA

was unable to determine whether any

such waters received discharges that, as

a consequence of the proposal,

henceforth could be subject to the

CWA’s permitting requirements.

Similarly, EPA did not evaluate

potential costs associated with

proposing to promulgate a regulation

that would require Kansas to apply the

implementation procedures in 40 CFR

131.34(f) when applying the States’

antidegradation policy (at K.A.R. 28–

16–28c(a)(1)(B)) to determine whether to

allow a lowering of surface waters

quality by point sources of pollution

where nonpoint sources also contribute

the pollutant of concern to that body of

water. EPA solicits any additional data

and information (e.g., where such

waters are located, how discharges are

permitted; concentrations of pollutants

in such discharges, etc.) that may assist

EPA in estimating potential indirect

costs to point and nonpoint sources of

pollution associated with this proposed

provision.

B. Selecting a Sample

Once EPA identified facilities

potentially affected by the proposed

rule, it selected a sample of facilities for

evaluation of potential compliance

costs. EPA stratified the potentially

affected facilities by major and minor

classification and included all major

facilities in each sample. EPA then drew

a random sample of potentially affected

minor facilities for evaluation. In

addition, EPA evaluated separately the

one facility discharging to the water

body lacking an aquatic life use. The

number of facilities identified and the

number of facilities used for cost

estimation are presented in the

following table.

C. Methodology for Estimating Potential

Compliance Costs

1. Proposed Designated Uses

EPA evaluated the separate samples of

facilities for potential costs resulting

from EPA’s proposal to designate waters

for primary contact recreation and

aquatic life support. For primary contact

recreation, EPA assumed that a sample

facility would have a reasonable

potential to exceed water quality criteria

for fecal coliforms (and require a permit

limit) if, for facilities with effluent data

for fecal coliforms, the maximum

effluent concentration exceeded the

most stringent water quality criterion

(the monthly average of 200 colonies per

100 ml). EPA also assumed a facility to

have reasonable potential to exceed

water quality criteria if a limit for fecal

coliforms is included in its existing

permit or if it discharges treated

domestic sewage that has not been

disinfected.

EPA assumed that projected effluent

limits would be the same as existing

water quality criteria for fecal coliforms

(a monthly geometric mean of 200

colonies per 100 ml and a weekly

geometric mean of 400 colonies per 100

ml) because existing EPA guidance

recommends this approach (U.S. EPA,

1977).

EPA assumed that a sample facility

would incur costs when its maximum

effluent concentration (or existing

permit limit, whichever is smaller)

exceeded the most stringent water

quality criterion for fecal coliforms. EPA

also assumed that a facility would incur

costs if it discharges domestic sewage

without a disinfection system currently

in place.

For this analysis, EPA assumed that

facilities with disinfection systems in

place but whose effluents do not comply

with projected effluent limits could be

brought into compliance with treatment

process optimization. EPA assumed that

UV light disinfection would be installed

at facilities with effluents containing

domestic sewage that do not have a

disinfection system in place.

One facility discharges to a stream

that is not designated as supporting

aquatic life uses. However, because

effluent data are not available for this

facility, EPA estimated that it does not

have reasonable potential to cause

exceedences of chronic aquatic criteria.

Consequently, EPA anticipates no cost

for this provision.

2. Proposal Regarding Assumed Flow

EPA analyzed reasonable potential for

all toxic pollutants with effluent data or

limits in existing NPDES permits under

two scenarios. For a low scenario, EPA

calculated a projected effluent quality

(PEQ) value for pollutants with effluent

data above detection levels. The PEQ is

an effluent value statistically adjusted

for uncertainty which EPA uses to

estimate a maximum value. The

methodology to derive a PEQ is based

on EPA’s Technical Support Document

for Water Quality-based Toxics Control

(TSD) (1991).

EPA then determined that waste load

allocations (WLAs) for each sample

facility would be equal to the chronic

criterion (or chronic continuous

concentration, CCC) because there

would be no dilution available (i.e., all

sample facilities had 7Q10 stream flows

equal to zero). WLAs for metals are

expressed in dissolved form (i.e., a

translator of one was used to convert

criteria from dissolved to total). EPA

estimated that a facility had reasonable

potential to exceed the water quality

criterion for a pollutant when its PEQ

exceeded the WLA. For the high

scenario, EPA assumed that a facility

had reasonable potential to exceed

water quality criteria for a pollutant if

it had a limit in its existing NPDES

permit or if it had reasonable potential

under the low scenario. EPA calculated

projected effluent limits based on the

methods recommended in EPA’s TSD.

Dischargers may be affected by EPA’s

proposed action if their current permit

limits or PEQs exceed projected effluent

limits developed using actual stream

flows. Affected dischargers would need

to implement measures to either reduce

pollutant concentrations in their

effluent or seek relief (e.g., through total

maximum daily loads (TMDLs), sitespecific criteria, or water quality

variances). EPA used different

approaches to estimate potential cost

impacts under its low and high

scenarios.

For the low scenario, EPA estimated

pollution control costs in situations

where the maximum effluent

concentration (MEC) exceeded projected

effluent limits and used the MEC as the

baseline effluent quality value.

However, if the MEC exceeded an

existing permit limit, EPA used the

existing permit limit as a baseline

concentration to avoid including costs

that are associated with complying with

current State regulations. EPA estimated

costs based on the incremental pollutant

loading reductions required to achieve

the projected limits. However, if the

annualized cost to remove a pollutant

exceeded $200 per toxic poundequivalent, EPA assumed that the

facility would pursue regulatory relief

(e.g., a variance) at a cost of $200,000

per pollutant (U.S. EPA, 1995). For the high scenario, EPA estimated

pollution control costs using the

existing permit limit as a baseline

effluent concentration. Where an

existing permit limit was not available,

EPA used the MEC as the baseline

effluent quality concentration. Again,

EPA estimated costs based on the

incremental pollutant loading

reductions required to achieve the

projected limits. However, EPA did not

assume that facilities would pursue

regulatory relief even if costs exceeded

$200 per toxic pound-equivalent. For both scenarios, EPA followed a

decision framework based on the

assumption that a facility would pursue

lower cost control strategies prior to

adding end-of-pipe treatment. EPA estimated loading reductions as

the difference between the baseline

Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules 41231

concentration and the projected

WQBEL. Note, however, that this

convention likely results in an upper

bound estimate of loading reductions

because facilities typically discharge at

levels below the MEC.

EPA converted pollutant loading

reductions from pounds (lbs) to toxic

pounds-equivalent (lbs-eq) using

toxicity weighting factors from the

Assessment of Compliance Costs

Resulting from Implementation of the

Final Great Lakes Water Quality

Guidance (U.S. EPA, 1995). EPA uses

the toxic weights presented in the Great

Lakes analysis to allow comparability of

cost-effectiveness among previous water

quality regulatory efforts. Toxicity

weighting factors are primarily derived

from EPA chronic freshwater aquatic

criteria and toxicity values, but are also

based on human health criteria when a

human health criterion has been

established. The toxicity weighting

factors used for the analysis are

standardized to the former copper water

quality criterion of 5.6 μg/L.

EPA did not evaluate reasonable

potential for non-toxic, conventional

pollutants (e.g., dissolved oxygen) for

facilities discharging to streams with a

7Q10 flow of less than one cfs. EPA

found that most of the sample facilities

do not have water quality-based effluent

limits for conventional pollutants in

existing NPDES permits. EPA solicits

effluent data and information on

treatment technologies currently in

place for conventional pollutants for

facilities discharging to streams with a

7Q10 flow of less than one cfs.

D. Results

1. Proposed Designated Uses

EPA estimated the costs associated

with its proposal to designate water

bodies for primary contact recreation

use and aquatic life use separately. For

primary contact recreation use, there are

154 potentially affected facilities out of

a total of 511 identified facilities.

However, EPA could not obtain reach

code information or location data to

determine if 337 facilities are affected or

not. For these facilities, EPA assumed

that the same percentage would be

affected as for identified facilities

(estimating separately for major and

minor facilities).

EPA estimated that the total statewide

cost associated with designating the

affected water bodies for primary

contact recreation would be

approximately $1.9 million. EPA

estimated that costs for major

dischargers are negligible because five

of the six major dischargers sampled

presently have disinfection facilities

and NPDES limits that are consistent

with primary contact recreation. For

minors, however, eight of the nine

sampled facilities do not have

disinfection facilities, effluent limits, or

monitoring data for fecal coliforms.

EPA estimated that the potential cost

associated with reinstating aquatic life

uses on the affected water bodies is

zero. However, this estimate is based on

the one affected facility that could be

identified.

2. Proposal Regarding Assumed Flow

For the assumed flow provision, there

are 116 potentially affected facilities out

of a total of 517 identified facilities.

However, EPA did not have information

to determine if 331 facilities are affected

or not. Again, for these facilities, EPA

assumed that the same percentage

would be affected as for identified

facilities (estimating separately for

major and minor facilities).

EPA estimated that the total statewide

cost may range from $28,000 to

$128,000 annually. The costs are

minimal because, of the ten sample

facilities, EPA anticipates that two

major facilities would incur pollutant

minimization control costs under the

high scenario. Under the low scenario,

only one major facility would require

some control, and EPA assumed that

this facility would pursue regulatory

relief. EPA does not anticipate any costs

for minor facilities because none of the

facilities have limits or data for toxic

pollutants.

EPA does not anticipate any resulting

pollutant loading reductions under the

low scenario. EPA anticipates small

reductions in the discharge of

chromium VI and copper under the high

scenario.

EPA did not evaluate potential costs

associated with removing the assumed

flow provision for conventional

pollutants. EPA recognizes that costs

associated with installing new treatment

technologies for treating conventional

pollutants could be significant. Facilityspecific cost analysis can be used to

support a variance from the State’s

standard, or to justify a lower aquatic

life use with less stringent criteria;

however, such information is not a basis

for assuming that dilution exists in

situations where the stream flow, at

times, is at or near zero. EPA’s proposed

rule, if finalized, would not affect the

State’s ability to issue pollutant-specific

variances where information shows that

one of the factors in 40 CFR 131.10(g)

are met, including information that

shows such water quality-based controls

would result in substantial and

widespread economic and social

impact. EPA’s cost analysis for the final

rule will fully address costs associated

with applying the 7Q10 to conventional

pollutants.

3. Total Statewide Costs

The following table summarizes the

total estimated statewide costs of the

proposed rule. The bulk of the costs are

attributable to the designation of

affected water bodies for primary

contact recreation use. As described

earlier, much of the costs for this

provision result from the need for minor

dischargers to install disinfection.

TOTAL ESTIMATED STATEWIDE COSTS BY PROVISION

Total ..................................................................................................................................................................................... 1,900,000–2,000,000

EPA recognizes that its identification

of facilities that may be affected by the

proposed rule is based on limited data.

EPA could not determine whether over

300 facilities would or would not be

affected because of a lack of data on

facility locations. While the assumption

that the proportion of facilities in this

indeterminate category that would be

affected would be similar to the

proportion of facilities known to be

affected by the proposed rule is

41232 Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules

reasonable, EPA solicits information

that would help resolve the universe of

facilities that would be affected. Should

the proportion of facilities in the

indeterminate category be substantially

different from the proportion of

facilities in the known category, then

statewide costs may also differ from

those reported here.

VII. Alternative Regulatory Approaches

and Implementation Mechanisms

In developing a final rule, EPA will

consider any data or information

submitted to the Agency by the close of

the comment period. However, it is

possible that data and information may

become available after completion of

this rulemaking that will be material to

water quality standards for Kansas. If

EPA ultimately promulgates Federal use

designations for Kansas, there are

several mechanisms available to ensure

that the water quality standards and

their implementing mechanisms

appropriately take into account such

new information. These mechanisms are

described in VII. A., B., C., and D.

The State should be aware, however,

that EPA considers designated use

changes, site-specific criteria, and

variances developed pursuant to this

provision to be modifications to the

State’s water quality standards. Federal

regulations at 40 CFR 122.44(d)(1)

require that NPDES permits include

limitations necessary to achieve water

quality standards adopted under section

303 of the CWA. Therefore, a designated

use change, a site-specific criterion, or

a variance cannot be the basis for

NPDES permit limitations until the

State has adopted it as part of its water

quality standards, has submitted it to

EPA and EPA has approved it. See 40

CFR 131.21(c) & (d). As with any other

revision to the State’s water quality

standards, EPA would then review these

revisions to determine whether they are

scientifically defensible in accordance

with 40 CFR 131.11(b)(1)(iii), or meet

the requirements of 40 CFR 131.10(g), as

applicable. EPA will also consider

whether the appropriate procedural

requirements have been met, such as

public participation and certification by

the appropriate legal authority within

the State. Therefore, if EPA promulgates

that regulation as proposed, then Kansas

would not be able to employ its

designated use changes, site-specific

criteria, and variances as a basis for

NPDES permit limits until Kansas

submits and EPA approves them.

A. Designating Uses

States have considerable discretion in

designating uses. The State may find

that changes in use designations are

warranted. As stated, EPA will review

any new or revised use designations

adopted by the State for any of the water

bodies in today’s proposal to determine

if the standards meet the requirements

of the CWA and implementing

regulations. If approved, EPA would

subsequently initiate withdrawal of any

final Federal water quality standards

which may result from today’s proposal.

However, EPA cautions the State that it

must conduct a use attainability

analyses as described in 40 CFR

131.10(g) when adopting water quality

standards that result in uses that are not

specified in section 101(a)(2) of the

CWA, or that result in subcategories of

uses specified in section 101(a)(2) that

require less stringent criteria.

B. Site-Specific Criteria

The State may also develop data that

indicates that a site-specific water

quality criterion for a particular

pollutant is appropriate, and then take

action to adopt such a criterion into its

water quality standards. Site specific

criteria are allowed by regulation and

are subject to EPA review and approval.

40 CFR 131.11 requires States to adopt

criteria that protect designated uses, that

are based on sound scientific rationale,

and that contain sufficient parameters or

constituents to protect the designated

use. In adopting water quality criteria,

States should establish numerical values

based on EPA’s recommended 304(a)

criteria guidance, 304(a) criteria

guidance modified to reflect site specific

conditions, or other scientifically

defensible methods, or should establish

narrative criteria where numerical

criteria cannot be determined or where

necessary to supplement narrative

criteria.

Currently, EPA guidance specifies

three procedures for States and Tribes to

follow in deriving site-specific criteria.

These are the Recalculation Procedure,

the Water-Effect Ratio Procedure and

the Resident Species Procedure. These

procedures can be found in the Water

Quality Standards Handbook (EPA–

823–B940005a, 1994). There is currently

draft guidance for the development of

site-specific criteria for the protection of

human health in the draft Methodology

for Deriving Ambient Water Quality

Criteria for the Protection of Human

Health. EPA also recognizes there may

be naturally occurring concentrations of

pollutants which may exceed the

national criteria published under

section 304(a) of the CWA, and has

issued policy guidance on establishing

site specific aquatic life criteria equal to

natural background. (Memo from Tudor

T. Davies, Director, Office of Science

and Technology to the Regional Water

Management Division Directors, and

State and Tribal Water Quality

Management Program Directors, dated

11/5/97.)

C. Variances

Water quality standards variances are

an alternative that can provide a facility

with a limited period of time to comply

with water quality standards. The

proposed rule contains a Federal

variance procedure for the designated

uses being proposed today. However,

the procedures described later in this

section can also be used by the State to

develop variances of State-adopted

water quality standards.

EPA believes variances are

particularly suitable when the cause of

nonattainment is discharger-specific

and it appears that the designated use in

question will eventually be attainable.

EPA has approved the granting of water

quality standards variances by States in

circumstances that would otherwise

justify changing a use designation on

grounds of unattainability (i.e., one or

more of the six circumstances contained

in 40 CFR 131.10(g)). In contrast to a

change in standards that removes a use

designation for a water body, a water

quality standards variance can apply

only to the discharger to whom it is

granted and only to the pollutant

parameter(s) upon which the finding of

unattainability was based, and only for

a limited period of time; the underlying

standard remains in effect for all other

purposes.

For example, if a designated aquatic

life use is currently precluded because

of high levels of metals from past

mining activities that cannot be

remediated in the short term, but it is

expected that water quality will

eventually improve, a temporary

variance may be granted to a discharger

with relaxed criteria for such metals,

until remediation progresses and the use

becomes attainable. The practical effect

of such a variance is to allow a permit

to be written using less stringent

criteria, while encouraging ultimate

attainment of the underlying standard.

A water quality standards variance

provides a mechanism for assuring

compliance with sections 301(b)(1)(C)

and 402(a)(1) of the CWA that require

NPDES permits to meet applicable water

quality standards, while granting

temporary relief to point source

dischargers.

While 40 CFR 131.13 allows States to

adopt variance procedures for Stateadopted water quality standards, such

State procedures may not be used to

grant variances from Federally adopted

standards. EPA believes that it is

appropriate to provide comparable

Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules 41233

Federal procedures where, as proposed

here, EPA adopts use designations

which rely, at least in part, on a

rebuttable presumption that fishable/

swimmable uses are attainable or adopts

more stringent criteria for the State’s use

designations. EPA is proposing to

authorize the Region VII Regional

Administrator to grant water quality

standards variances where a permittee

submits data indicating that an EPAdesignated use is not attainable for any

of the reasons in 40 CFR 131.10(g).

Therefore today’s rule proposes variance

procedures that would apply to the

designated uses promulgated by EPA for

the specific stream segments named in

today’s proposal at proposed 40 CFR

131.34(g) and (h).

Today’s proposed rule spells out the

process for applying for and granting

such variances. Authorizing the

Regional Administrator to grant

variances should expedite the

processing of variance requests. EPA is

proposing to use informal adjudication

processes in reviewing and granting

variance requests. That process is

contained in 131.34(i) of today’s

proposed rule. Because water quality

standards variances, technically

speaking, are revised water quality

standards, the proposal provides that

the Regional Administrator will provide

public notice of the proposed variance

and provide an opportunity for public

comment. EPA understands that

variance-related issues can often arise in

the context of permit issuance. EPA

Region VII will seek to work closely

with the State permitting authorities to

ensure that variance requests will be

considered in tandem with the State

NPDES permitting process.

The proposed variance procedures

would require an applicant for a water

quality standards variance to submit a

request to the Regional Administrator

(or his delegatee) with supporting

information.

Under its proposal, as in the national

program, the burden is on the applicant

to demonstrate to EPA’s satisfaction that

the designated use is unattainable for

one of the reasons specified in 40 CFR

131.10(g). A variance may not be

granted if the use could be attained, at

a minimum, by all dischargers

implementing effluent limitations

required under sections 301(b) and 306

of the CWA and the applicant

implementing reasonable best

management practices for nonpoint

source control.

Under the proposal, a variance may

not exceed three years or the term of the

NPDES permit, whichever is less. A

variance may be renewed if the

permittee demonstrates that the use in

question is still not attainable. Renewal

of the variance may be denied if EPA

finds that the conditions of 40 CFR

131.10(g) are not met.

EPA is soliciting comment on the

need for a variance process for EPApromulgated use designations, the

appropriateness of the particular

procedures proposed today, and

whether the proposed variance

procedures are sufficiently detailed.

D. Total Maximum Daily Loads (TMDLs)

State development of TMDLs is an

alternative approach for allocating loads

of pollutants and ensuring attainment of

designated uses in these water bodies.

Section 303(d) of the CWA and its

implementing regulations establish the

TMDL process to provide a mechanism

for allocating more stringent water

quality-based requirements when

technology-based controls and other

controls are inadequate to achieve

applicable water quality standards. The

TMDL process can broaden the

opportunity for public participation,

expedite water quality-based NPDES

permitting, and lead to technically

sound and legally defensible decisions

for attaining and maintaining water

quality standards. In addition, the

TMDL process provides a mechanism

for integrating the management of both

point and nonpoint pollution sources

that together may contribute to a water

body’s impairment. (See: Guidance for

Water Quality-based Decisions: The

TMDL Process, EPA 440–4–91–001,

April 1991.)

VIII. Administrative Requirements and

Related Government Acts

A. Executive Order 12866: Regulatory

Planning and Review

Under Executive Order 12866 (58 FR

51735, October 4, 1993), EPA must

determine whether a regulatory action is

‘‘significant’’ and therefore subject to

Office of Management and Budget

(OMB) review and the requirements of

the Executive Order. The Executive

Order defines ‘‘significant regulatory

action’’ as one that is likely to result in

a rule that may:

(1) Have an annual effect on the

economy of $100 million or more or

adversely affect in a material way the

economy, a sector of the economy,

productivity, competition, jobs, the

environment, public health or safety, or

State, local, or Tribal governments or

communities;

(2) Create a serious inconsistency or

otherwise interfere with an action taken

or planned by another agency;

(3) Materially alter the budgetary

impact of entitlements, grants, user fees,

or loan programs or the rights and

obligations of recipients thereof; or

(4) Raise novel legal or policy issues

arising out of legal mandates, the

President’s priorities, or the principles

set forth in the Executive Order.

Pursuant to the terms of the Executive

Order 12866, it has been determined

that this rule is a ‘‘significant regulatory

action.’’ As such, this action was

submitted to OMB for review. Changes

made in response to OMB suggestions or

recommendations will be documented

in the public record.

B. The Regulatory Flexibility Act (RFA),

As Amended by the Small Business

Regulatory Enforcement Fairness Act of

1996 (SBREFA), 5 U.S.C. 601 et seq.

The Regulatory Flexibility Act (RFA)

as amended by the Small Business

Regulatory Enforcement Fairness Act of

1996 (SBREFA) (5 U.S.C. 601 et seq.),

generally requires an agency to prepare

a regulatory flexibility analysis of any

rule subject to notice and comment

rulemaking requirements under the

Administrative Procedure Act or any

other statute unless the agency certifies

that the rule will not have a significant

economic impact on a substantial

number of small entities. Small entities

include small businesses, small

organizations and small governmental

jurisdictions.

For purposes of assessing the impacts

of today’s proposed rule on small

entities, small entity is defined as: (1) A

small business according to RFA default

definitions for small business (based on

SBA size standards); (2) a small

governmental jurisdiction that is a

government of a city, county, town,

school district or special district with a

population of less than 50,000; and (3)

a small organization that is any not-forprofit enterprise which is independently

owned and operated and is not

dominant in its field.

After considering these economic

impacts of today’s proposed rule on

small entities, the Administrator hereby

certifies that this action will not have a

significant economic impact on a

substantial number of small entities.

This proposed rule will not impose any

requirements on small entities. The RFA

requires analysis of the impacts of a rule

on the small entities subject to the rule’s

requirements. See United States

Distribution Companies v. FERC, 88

F.3d 1105, 1170 (D.C. Cir. 1996).

Today’s proposed rule establishes no

requirements applicable to small

entities, and so is not susceptible to

regulatory flexibility analysis as

prescribed by the RFA. (‘‘[N]o

[regulatory flexibility] analysis is

necessary when an agency determines

41234 Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules

that the rule will not have a significant

economic impact on a substantial

number of small entities that are subject

to the requirements of the rule,’’ United

Distribution at 1170, quoting Mid-Tex

Elec. Co-op v. FERC, 773 F.2d 327, 342

(D.C. Cir. 1985) (emphasis added by

United Distribution court).) The Agency

is thus certifying that today’s proposed

rule will not have a significant

economic impact on a substantial

number of small entities, within the

meaning of the RFA.

Under the CWA water quality

standards program, States must adopt

water quality standards for their waters

and must submit those water quality

standards to EPA for approval; if the

Agency disapproves a State standard

and the State does not adopt appropriate

revisions to address EPA’s disapproval,

EPA must promulgate standards

consistent with the statutory

requirements. EPA also has the

authority to promulgate criteria or

standards in any case where the

Administrator determines that a new or

revised standard is necessary to meet

the requirements of the Act. These State

standards (or EPA-promulgated

standards) are implemented through

various water quality control programs

including the National Pollutant

Discharge Elimination System (NPDES)

program, which limits discharges to

navigable waters except in compliance

with an EPA permit or a permit issued

under an approved State program. The

CWA requires that all NPDES permits

include any limits on discharges that are

necessary to meet applicable water

quality standards.

Thus, under the CWA, EPA’s

promulgation of water quality standards

establishes standards that the State

implements through the NPDES permit

process. The State has discretion in

deciding how to meet the water quality

standards and in developing discharge

limits as needed to meet the standards.

While the State’s implementation of

Federally promulgated water quality

standards may result in new or revised

discharge limits being placed on small

entities, the standards themselves do

not apply to any discharger, including

small entities.

Today’s proposed rule, as explained

earlier, does not itself establish any

requirements that are applicable to

small entities. As a result of this action,

the State of Kansas will need to ensure

that permits it issues include any

limitations on discharges necessary to

comply with the standards established

in the final rule. In doing so, the State

will have a number of discretionary

choices associated with permit writing.

While Kansas’s implementation of the

rule may ultimately result in some new

or revised permit conditions for some

dischargers, including small entities,

EPA’s action today does not impose any

of these as yet unknown requirements

on small entities.

C. The Paperwork Reduction Act

This rule imposes no new or

additional information collection

requirements. Therefore, this rule is not

subject to the Paperwork Reduction Act.

D. The Unfunded Mandates Reform Act

of 1995

Title II of the Unfunded Mandates

Reform Act of 1995 (UMRA), Public

Law 104–4, establishes requirements for

Federal agencies to assess the effects of

their regulatory actions on State, local,

and Tribal governments and the private

sector. Under section 202 of the UMRA,

EPA generally must prepare a written

statement, including a cost-benefit

analysis, for proposed and final rules

with ‘‘Federal mandates’’ that may

result in expenditures to State, local,

and Tribal governments, in the

aggregate, or to the private sector, of

$100 million or more in any one year.

Before promulgating an EPA rule for

which a written statement is needed,

section 205 of the UMRA generally

requires EPA to identify and consider a

reasonable number of regulatory

alternatives and adopt the least costly,

most cost-effective or least burdensome

alternative that achieves the objectives

of the rule. The provisions of section

205 do not apply when they are

inconsistent with applicable law.

Moreover, section 205 allows EPA to

adopt an alternative other than the least

costly, most cost-effective or least

burdensome alternative if the

Administrator publishes with the final

rule an explanation of why that

alternative was not adopted. Before EPA

establishes any regulatory requirements

that may significantly or uniquely affect

small governments, including Tribal

governments, it must have developed

under section 203 of the UMRA a small

government agency plan. The plan must

provide for notifying potentially

affected small governments, enabling

officials of affected small governments

to have meaningful and timely input in

the development of EPA regulatory

proposals with significant Federal

intergovernmental mandates, and

informing, educating, and advising

small governments on compliance with

the regulatory requirements.

Today’s proposed rule contains no

Federal mandates (under the regulatory

provisions of Title II of the UMRA) for

State, local or Tribal governments or the

private sector. The proposed rule

imposes no enforceable duty on the

State or any local or Tribal government

or the private sector; rather, this rule

proposes designated uses for certain

waterbodies in Kansas which, when

combined with State adopted water

quality criteria, constitute water quality

standards for those waterbodies. The

State may use these resulting water

quality standards in implementing its

water quality control programs. Today’s

proposed rule does not regulate or affect

any entity and, therefore, is not subject

to the requirements of sections 202 and

205 of the UMRA.

EPA has determined that this

proposed rule contains no regulatory

requirements that might significantly or

uniquely affect small governments. As

stated, the proposed rule imposes no

enforceable requirements on any party,

including small governments. Moreover,

any water quality standards, including

those proposed here, apply broadly to

dischargers and are not uniquely

applicable to small governments. Thus,

this proposed rule is not subject to the

requirements of section 203 of UMRA.

E. Executive Order 13132: Federalism

Executive Order 13132, entitled

‘‘Federalism’’ (64 FR 43255, August 10,

1999) requires EPA to develop an

accountable process to ensure

‘‘meaningful and timely input by State

and local officials in the development of

regulatory policies that have federalism

implications.’’ ‘‘Policies that have

federalism implications’’ is defined in

the Executive Order to include

regulations that have ‘‘substantial direct

effects on the States, on the relationship

between the national government and

the States, or on the distribution of

power and responsibilities among the

various levels of government.’’

Under section 6 of Executive Order

13132, EPA may not issue a regulation

that has federalism implications, that

imposes substantial direct compliance

costs, and that is not required by statute,

unless the Federal government provides

the funds necessary to pay the direct

compliance costs incurred by State and

local governments, or EPA consults with

State and local officials early in the

process of developing the proposed

regulation. EPA also may not issue a

regulation that has federalism

implications and that preempts State

law, unless the Agency consults with

State and local officials early in the

process of developing the proposed

regulation.

This proposed rule does not have

federalism implications. It will not have

substantial direct effects on the States,

on the relationship between the national

government and the States, or on the

Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules 41235

distribution of power and

responsibilities among the various

levels of government, as specified in

Executive Order 13132. The proposed

rule would not affect the nature of the

relationship between EPA and States

generally, for the rule only applies to

waterbodies in Kansas. Further, the

proposed rule would not substantially

affect the relationship of EPA and the

State of Kansas, or the distribution of

power or responsibilities between EPA

and the various levels of government.

The proposed rule would not alter the

State’s authority to issue NPDES permits

or the State’s considerable discretion in

implementing these water quality

standards. Further, this proposed rule

would not preclude Kansas from

adopting water quality standards that

meet the requirements of the CWA.

Thus, the requirements of section 6 of

the Executive Order do not apply to this

proposed rule.

Although section 6 of Executive Order

13132 does not apply to this rule, EPA

did consult with State and local

government representatives in

developing this proposed rule. A

summary of the concerns raised during

that consultation and EPA’s response to

those concerns is provided later in this

section. In its communications with

EPA, KDHE expressed concern that

some of the standards disapproved by

EPA in 1998 and for which EPA is today

proposing Federal replacement

regulations, would result in substantial

costs to small communities without

significant environmental benefits.

Chief among these issues was EPA’s

disapproval of the Kansas assumed low

flow provision, that allows discharges to

water bodies with a 7Q10 flow of less

than 1 cubic foot per second (cfs) to use

an assumed 7Q10 of 1 cfs in setting

permit limits. EPA disapproved this

provision in the State standards because

it allows water quality-based NPDES

permit limits to be derived based on

dilution that does not exist. As

explained previously, the economic

impact of meeting water quality

standards may be taken into

consideration by the State in making

site-specific determinations during

preparation of use attainability analyses

and variances, but not in adopting water

quality standards for statewide

implementation.

F. Executive Order 13084: Consultation

and Coordination With Indian Tribal

Governments

Under Executive Order 13084, EPA

may not issue a regulation that is not

required by statute, that significantly or

uniquely affects the communities of

Indian Tribal governments, and that

imposes substantial direct compliance

costs on those communities, unless the

Federal government provides the funds

necessary to pay the direct compliance

costs incurred by the Tribal

governments, or EPA consults with

those governments. If EPA complies by

consulting, Executive Order 13084

requires EPA to provide to the Office of

Management and Budget, in a separately

identified section of the preamble to the

rule, a description of the extent of EPA’s

prior consultation with representatives

of affected Tribal governments, a

summary of the nature of their concerns,

and a statement supporting the need to

issue the regulation. In addition,

Executive Order 13084 requires EPA to

develop an effective process permitting

elected officials and other

representatives of Indian Tribal

governments ‘‘to provide meaningful

and timely input in the development of

regulatory policies on matters that

significantly or uniquely affect their

communities.’’

Today’s proposed rule does not

significantly or uniquely affect the

communities of Indian Tribal

governments, nor does it impose

substantial direct compliance costs on

them. In this proposed action, EPA

expressly excludes waters in Indian

country. Therefore, the requirements of

section 3(b) of Executive Order 13084

do not apply to this proposed rule.

G. The Endangered Species Act

Section 7 of the Endangered Species

Act (ESA), 16 U.S.C. 1536, requires

Federal agencies, in consultation with

the U.S. Fish and Wildlife Service

(FWS) and National Marine Fisheries

Service (NMFS), to ensure their actions

are not likely to jeopardize the

continued existence of any listed

species or result in the destruction or

adverse modification of habitat of such

species which have been designated as

‘‘critical.’’ Consultation is designed to

assist Federal agencies in complying

with the requirements of section 7 by

supplying a process within which FWS

and NMFS provide such agencies with

advice and guidance on whether an

action complies with the substantive

requirements of ESA.

EPA initiated informal consultation

with the FWS under section 7 of the

ESA in November 1997 regarding EPA’s

planned action to approve in part, and

disapprove in part, water quality

standards revisions submitted by Kansas

in 1994. By letter dated February 19,

1998, the FWS notified EPA that it

concurred with EPA’s determination

that the partial approval, and partial

disapproval of the Kansas water quality

standards revisions of 1994 should not

adversely impact Federally-listed and

endangered species. EPA continued to

correspond with the FWS throughout

the period during which Kansas revised

its water quality standards and

submitted them to EPA for approval in

August 1999.

EPA continued its consultation with

FWS under section 7 of the ESA

regarding EPA’s planned approval of

some of the 1999 revisions to the Kansas

water quality standards that corrected

standards previously disapproved by

EPA in its 1998 action. As a result of

this consultation, the FWS issued a

biological opinion dated January 6,

2000, regarding the State of Kansas’

Water Quality Standards program. The

opinion concurred with EPA’s

determination that EPA’s partial

approval of the 1999 revisions to the

Kansas water quality standards program

should have no adverse effect on any

Federally listed species or species

proposed for listing.

In its January 6, 2000, letter, FWS also

indicated that it would continue to

coordinate ‘‘with EPA to resolve the

disapproval issues in the State action.’’

EPA continues to actively consult with

FWS regarding this action to establish

Federal water quality standards in

Kansas and plans to conclude

consultation on these proposed Federal

standards before taking final action.

H. The National Technology Transfer

and Advancement Act

Section 12(d) of the National

Technology Transfer and Advancement

Act of 1995 (NTTAA) Public Law

No.104–113, 12(d) (15 U.S.C. 272 note)

directs EPA to use voluntary consensus

standards in its regulatory activities

unless to do so would be inconsistent

with applicable law or otherwise

impractical. Voluntary consensus

standards are technical standards (e.g.,

materials specifications, test methods,

sampling procedures, and business

practices) that are developed or adopted

by voluntary consensus standards

bodies. The NTTAA directs EPA to

provide Congress, through the Office of

Management and Budget, explanations

when the Agency decides not to use

available and applicable voluntary

consensus standards.

This proposed rulemaking does not

involve technical standards. Therefore,

EPA is not considering the use of any

voluntary consensus standards.

Nevertheless, EPA welcomes comments

on this aspect of the proposed

rulemaking and specifically invites the

public to identify potentially-applicable

voluntary consensus standards and to

explain why such standards should be

used in this regulation.

41236 Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules

I. Executive Order 13045: Protection of

Children From Environmental Health

Risks and Safety Risks

Executive Order 13045: Protection of

Children from Environmental Health

Risks and Safety Risks (62 FR 19885,

April 23, 1997) applies to any rule that:

(1) Is determined to be ‘‘economically

significant’’ as defined under Executive

Order 12866, and (2) concerns an

environmental health or safety risk that

EPA has reason to believe may have a

disproportionate effect on children. If

the regulatory action meets both criteria,

the Agency must evaluate the

environmental health or safety effects of

the planned rule on children, and

explain why the planned regulation is

preferable to other potentially effective

and reasonably feasible alternatives

considered by the Agency.

This proposed rule is not subject to

the Executive Order because it is not

economically significant as defined in

Executive Order 12866, and because the

Agency does not have reason to believe

the environmental health or safety risks

addressed by this action present a

disproportionate risk to children. This

rule establishes water quality standards

o meet the requirements of the CWA

and the implementing Federal

regulations.

The public is invited to submit or

identify peer-reviewed studies and data,

of which the agency may not be aware,

that indicates these water quality

standards are not adequate to protect

children’s health.

J. Executive Order 12886: Plain

Language

Executive Order 12886 and the

President’s memorandum of June 1,

1998 require each agency to write all

rules in plain language. We invite your

comments on how to make this

proposed rule easier to understand. For

example:

—Have we organized the material to suit

your needs?

—Are the requirements in the rule

clearly stated?

—Does the rule contain technical

language or jargon that isn’t clear?

—Would a different format (grouping

and order of sections, use of headings,

paragraphing) make the rule easier to

understand?

—Would more (but shorter) sections be

better?

—What else could we do to make the

rule easier to understand?

List of Subjects in 40 CFR Part 131

Environmental protection, Indianslands, Reporting and recordkeeping

requirements, Water pollution control.

Dated: June 16, 2000.

Carol M. Browner,

Administrator.

For the reasons set forth in the

preamble, EPA proposes to amend 40

CFR part 131 as follows:

PART 131—WATER QUALITY

STANDARDS

1. The authority citation for part 131

continues to read as follows:

Authority: 33 U.S.C. 1251 et seq.

Subpart D—[Amended]

2. Section 131.34 is added to read as

follows:

§ 131.34 Kansas.

(a) Do Kansas’ water quality standards

apply to ‘‘privately owned surface

waters’? The State’s water quality

standards apply to all waters of the U.S.

within the jurisdiction of the State.

(b) What criteria apply to the

Domestic Water Supply Use in Kansas?

In addition to the criteria specified at

K.A.R. 28–16–28e(c)(3) and at § 131.36

of this Part for Kansas, the following

criteria apply to Kansas surface waters

designated for Domestic Water Supply

Use:

Pollutant Criterion

alpha-endosulfan ............... 110 μgliter.

beta-endosulfan ................. 110 μgliter.

(c) What uses must be protected for

stream segments in Kansas for which

continuous flow is sustained primarily

through the discharge of treated

effluent? Designated uses at K.A.R. 28–

16–28d and K.A.R. 28–16–28e for

stream segments for which continuous

flow is sustained primarily through the

discharge of treated effluent must be

protected (irrespective of the

development of a use attainability

analysis that demonstrates that a

different use may be appropriate) until

EPA approves a revision to the

applicable use designation.

(d) What design flow applies when

establishing mixing zones to implement

chronic aquatic life criteria in Kansas?

The design flow of 7Q10, 4B3, or other

scientifically defensible design flows

approved by EPA shall be used in

calculating the mixing zone crosssectional area or volumetric flow in the

implementation of chronic aquatic life

criteria:

(1) Under K.A.R. 28–16–28c(b)(7)for

discharges of all pollutants to any

surface waters designated in Kansas as

exceptional State waters; and

(2) Under K.A.R. 28–16–28c(b)(8), (A)

through (C), for discharges of all

pollutants to any surface waters

designated in Kansas as general purpose

waters, including special aquatic life

use waters, expected aquatic life use

waters, and restricted aquatic life use

waters.

(e) What design flow applies when

establishing mixing zones to implement

acute aquatic life criteria in Kansas?

The design flow of 1Q10, 1B3, or other

scientifically defensible design flows

approved by EPA shall be used in

calculating the mixing zone crosssectional area or volumetric flow in the

implementation of acute aquatic life

criteria:

(1) Under K.A.R. 28–16–28c(b)(7)for

discharges of all pollutants to any

surface waters designated in Kansas as

exceptional State waters; and

(2) Under K.A.R. 28–16–28c(b)(8), (A)

through (C), for discharges of all

pollutants to any surface waters

designated in Kansas as general purpose

waters, including special aquatic life

use waters, expected aquatic life use

waters, and restricted aquatic life use

waters.

(f) What procedures apply to

implement the provisions of Kansas’

antidegradation requirements that

would allow the lowering of surface

water quality by point sources where

nonpoint sources also contribute the

pollutant of concern to that body of

water? The following implementation

procedures are for use when applying

K.A.R. 28–16–28c(a)(1)(B) to determine

whether to allow a lowering of surface

water quality by point sources of

pollution where nonpoint sources also

contribute the pollutant of concern to

that body of water:

(1) Identification of significant

sources (or categories) of nonpoint

pollution that may impact a high quality

water body by releasing the pollutants

of concern;

(2) Identification of reasonable and

cost-effective best management practices

(BMPs) for each of these significant

nonpoint sources or source categories;

and

(3) Determination that significant

nonpoint sources in those nonpoint

source categories will implement

appropriate BMPs.

(g) In addition to the State-adopted

use designations, the following water

body in Kansas is designated for

expected aquatic life use.

(i) Standards will be attained by

implementing effluent limitations

required under sections 301(b) and 306

of the CWA and by the permittee

implementing reasonable best

management practices for nonpoint

source control; or

(ii) The variance would likely

jeopardize the continued existence of

any threatened or endangered species

listed under section 4 of the Endangered

Species Act or result in the destruction

or adverse modification of such species’

critical habitat.

(3) Subject to paragraph (b)(2) of this

section, a water quality standards

variance may be granted if the applicant

demonstrates to EPA that attaining the

water quality standard is not feasible

because:

(i) Naturally occurring pollutant

concentrations prevent the attainment of

the use; or

(ii) Natural, ephemeral, intermittent

or low flow conditions or water levels

prevent the attainment of the use, unless

these conditions may be compensated

for by the discharge of sufficient volume

of effluent discharges without violating

State water conservation requirements

to enable uses to be met; or

(iii) Human caused conditions or

sources of pollution prevent the

attainment of the use and cannot be

remedied or would cause more

environmental damage to correct than to

leave in place; or

(iv) Dams, diversions or other types of

hydrologic modifications preclude the

attainment of the use, and it is not

feasible to restore the water body to its

original condition or to operate such

modification in a way which would

result in the attainment of the use; or

(v) Physical conditions related to the

natural features of the water body, such

as the lack of a proper substrate, cover,

flow, depth, pools, riffles, and the like

unrelated to water quality, preclude

attainment of aquatic life protection

uses; or

(vi) Controls more stringent than

those required by sections 301(b) and

306 of the CWA would result in

substantial and widespread economic

and social impact.

(4) Procedures. An applicant for a

water quality standards variance shall

submit a request to the Regional

Administrator of EPA Region 7. The

application shall include all relevant

information showing that the

requirements for a variance have been

satisfied. The burden is on the applicant

to demonstrate to EPA’s satisfaction that

the designated use is unattainable for

one of the reasons specified in

paragraph (i)(3) of this section. If the

Regional Administrator preliminarily

determines that grounds exist for

granting a variance, he shall provide

public notice of the proposed variance

and provide an opportunity for public

comment. Any activities required as a

condition of the Regional

Administrator’s granting of a variance

shall be included as conditions of the

NPDES permit for the applicant. These

terms and conditions shall be

incorporated into the applicant’s NPDES

permit through the permit reissuance

process or through a modification of the

permit pursuant to the applicable

Federal Register / Vol. 65, No. 128 / Monday, July 3, 2000 / Proposed Rules 41263

permit modification provisions of

Kansas’ NPDES program.

(5) A variance may not exceed 3 years

or the term of the NPDES permit,

whichever is less. A variance may be

renewed if the applicant reapplies and

demonstrates that the use in question is

still not attainable. Renewal of the

variance may be denied if the applicant

did not comply with the conditions of

the original variance, or otherwise does

not meet the requirements of this

section.
