Findings

(a) The Confederated Tribes of the Colville Reservation have a primary interest in the protection, control,

conservation, and utilization of the water resources of the Colville Indian Reservation. It is the purpose of

this Chapter to establish Tribal Water Quality Standards for the surface waters and ground waters located

within the exterior boundaries of the Colville Indian Reservation. The quality of all surface and

groundwater on the Reservation shall be protected to insure the health, economic, aesthetic and cultural

well being of all people residing upon the Colville Indian Reservation.

(Amended 9/2/10, Certified 9/9/10, Resolution 2010-622)

(b) The human activities and factors which may adversely affect the quality of surface and ground waters

on the Colville Indian Reservation and the natural resources which they support shall be regulated to protect

and maintain the high quality of such waters and preserve their continued domestic, agricultural, industrial,

recreational, cultural and other beneficial uses. The economy, health, safety and welfare of the people

residing and doing business on the Colville Indian Reservation may be adversely affected by human

activities carried out by both Indian and non-Indian people on trust and fee land within the Colville Indian

Reservation. Inadequate control of such activities can contaminate and degrade surface and groundwater

resources on which many people depend for domestic, agricultural, industrial, business, recreational,

cultural and other uses.

Standards in order to protect the economy, health, safety and welfare of the Reservation community.

Territory Covered

The provisions of this Chapter, known as the Water Quality Standards Chapter of the Colville Law and

Order Code, shall apply to all surface and groundwaters of the Colville Indian Reservation. Every human

activity taking place on the Colville Indian Reservation which may affect the quality of the surface and

groundwater resources of the Reservation shall be subject to the provisions of this Chapter.

General Considerations

The following general guidelines shall apply to the Water Quality Standards and classifications set forth in

sections 4-8-6 through 4-8-8.

(a) At the boundary between waters of different classifications, the Water Quality Standards for the higher

classification shall prevail.

(b) The Water Quality Standards herein established shall not apply within an authorized dilution zone

adjacent to or surrounding a wastewater discharge.

Standards.

(1) However, persons discharging wastes in compliance with the terms and conditions of permits

shall not be subject to civil penalties on the basis that the discharge violated Tribal Water Quality

(September 2010 version of Chapter 4-8)

Standards.

(2) Permits shall be subject to modification by the Department whenever it appears to the

Department that the discharge may violate Tribal Water Quality Standards. Modifications of

permits, as provided herein, shall be subject to the same administrative review procedures as

originally issued permits.

(d) Non-Point Sources and Tribal Water Quality Standards:

(1) It is recognized that many activities not subject to a waste discharge permit system are now

taking place within the Reservation and it is further recognized that such activities may be in

conflict with applicable Tribal Water Quality Standards until such time as a regulatory program is

in place to control such non-permitted activities. Any such regulatory program shall provide

methods or means whereby such activities shall comply with Tribal Water Quality Standards.

Person conducting non-point source activities for which a regulatory program may be developed

may however, not be subject to civil sanctions for violation of Tribal Water Quality Standards if

such activities are either:

(A) Conducted in accordance with applicable best management practices set forth by the

Tribe; or

(B) Subject to and in compliance with any regulatory order(s) issued by the Department.

(2) Best management practices or regulatory orders described in subsection 4-8-5(d)(1) shall be

subject to modification by either the Council or the Department whenever it appears that the

discharge may violate Tribal Water Quality Standards. Modification of best management practices

or regulatory orders, as provided herein, shall be subject to the same administrative review

procedures as the originally issued best management practices or regulatory orders.

(e) The Water Quality Standards herein established for the total dissolved gas shall not apply when the

stream flow exceeds the seven (7) day, ten (10) year frequency flood.

(f) The total area and/or volume of a receiving water assigned to a dilution zone shall be as described in a

valid discharge permit as needed and shall be limited to that which will:

(1) Not cause acute moralities or sport, food, or commercial fish and shellfish species of

established biological communities within populations or important species to a degree which

damages the ecosystem; and

(2) Not diminish aesthetic values or other beneficial uses disproportionately.

(g) The antidegradation policy of the Tribe, which is a regulatory requirement of this Chapter shall be

applicable to all surface and ground waters of the Reservation. The antidegradation policy provides that:

(1) Existing beneficial uses shall be maintained and protected and no further degradation which

would interfere with or become injurious to existing beneficial uses shall be allowed.

(2) No further degradation of any surface or ground waters lying within areas designated as unique

water quality management areas shall be allowed.

(3) Whenever surface or ground waters are in fact of a higher quality than provided for by

applicable Water Quality Standards, the existing higher water quality shall be protected. Wastes,

other materials, and substances which may reduce the existing quality of such surface or ground

(September 2010 version of Chapter 4-8)

waters shall not be allowed to enter such waters. Except that the Department may allow such

wastes, other materials, and substances to be placed in such waters in those instances where:

(A) It is clear that overriding considerations of the public interest will be served thereby,

and

(B) All wastes and other materials and substances proposed for discharge into the said

waters shall have first been subject to all known, available, and reasonable methods of

treatment prior to such discharge.

(4) Whenever the natural conditions of surface or ground waters in their unaltered state and not

affected by human activity are of a lower quality than the Water Quality Standards assigned

thereto by this Chapter, the natural conditions shall constitute the applicable Water Quality

Standards.

(5) The criteria and special conditions established in sections 4-8-6 through 4-8-8 may be modified

for a specific water body, on a temporary basis not to exceed sixty (60) days, when necessary to

accommodate essential activities, respond to emergencies, or to otherwise protect the public

interest. Such modification may for good cause be extended for an additional sixty (60) days. All

such modifications shall be issued in writing by the Director or his designee subject to such terms

and conditions as he or she may prescribe. The aquatic application of herbicides which may result

in water use restrictions shall be considered an activity for which a temporary modification may

generally be issued subject to conditions specified by the Department.

(6) No degradation of water quality shall be allowed if such degradation may interfere with or

become injurious to existing water uses or may cause long-term or irreparable harm to the

Reservation environment.

(7) No waste discharge permit shall be issued for any proposed discharge which may violated

established Water Quality Standards, except as provided for under section 4-8-9(c).

(h) In applying Water Quality Standards the Department shall give due consideration to the precision and

accuracy of the sampling and analytical methods used as well as existing conditions at the time.

(i) The analytical testing methods used to measure or otherwise evaluate Water Quality Standards shall to

the extent practicable, be in accordance with the most recent editions of “Standard Methods for the

Examination of Water and Wastewater,” published by the American Public Health Association, American

Water Works Association, and the Water Pollution Control Federation, and “Methods for Chemical

Analysis of Water and Wastes,” published by the EPA, and other or superseding methods published and/or

approved by the Department following consultation with and concurrence of the EPA.

(j) Deleterious concentrations of radioactive materials for all classes shall be as determined by the lowest

practicable concentration attainable and in no case shall exceed EPA Drinking Water Regulations for

radionuclides, as published in the Federal Register of July 9, 1976, or subsequent revisions thereof.

(k) Deleterious concentrations of toxic, or other non-radio-active materials, shall be determined by the

Department in consideration of the “Quality Criteria for Water,” published by EPA in 1976, and as revised,

as an authoritative source for criteria and/or other relevant information.

(l) Nothing in this Chapter shall be interpreted to prohibit the establishment of effluent limitations for the

control of the thermal component of any discharge in accordance with Section 316 of the Federal Clean

Water Act (P.L. 95-217 as amended).

(a) No person shall discharge any waste from a point source into Reservation waters without having first

obtained a permit from either the BPA or the Department, as applicable.

(b) The Department may, through the issuance of regulatory permits, directives, and orders, control

miscellaneous waste discharge not covered by section 4-8-9(a).

reduce water quality below those set by this Chapter (4-8-5 and 4-8-6) when such activities found to be

overriding public benefit, provided that all such temporary authorizations shall be for a thirty (30) day

period or less.

(d) The Department may in furtherance of section 4-8-9(b) require any prospective or current discharge to,

among other things, perform such water quality monitoring tasks as might be necessary to determine the pre

and post discharge conditions, mixing zone requirements, and permit parameters.

(e) To ascertain whether the regulations, waste disposal permits, orders, and directives promulgated and/or

issued by the Department, the Council, or EPA are being complied with a continuing surveillance program

shall be conducted by the Department. This continuing surveillance program shall include, among other

things, the following:

(1) Inspecting treatment and control facilities;

(2) Monitoring and reporting waste discharge characteristics; and

(3) Monitoring receiving water quality.

(September 2010 version of Chapter 4-8)

4-8-10 Violations, Enforcement and Civil Penalties

(a) The Department shall be notified of all suspected violations and accidental discharges.

(1) Any person may apply in writing to the Department and the Department will initiate an

investigation and take action upon any suspected or alleged violation of any provision of this

Chapter or of any order, permit, or regulation issued or promulgated under the authority of this

Chapter.

(2) Any person engaged in any operation or activity which results in a spill or discharge which

may cause pollution of the water of the Reservation contrary to this Chapter shall immediately

notify the Department. Any person who fails to notify the Department as soon as he either knows

or should have known about the spill or discharge is deemed in violation of this Chapter and, upon

an administrative finding thereof after notice and hearing as provided by the Colville

Administrative Procedures Act, shall be levied an administrative civil penalty of not more than ten

thousand dollars ($10,000) per day that such violation continues.

(b) Notice of Alleged Violations:

(1) Wherever the Department has reason to believe that there has occurred a violation of an order,

permit, or other requirement issued or promulgated under authority of this Chapter, the Director

shall cause written notice to be served personally or by certified mail return-receipt requested upon

the alleged violator or its agent for service of process. The notice shall state the provision alleged

to be violated, the facts alleged to constitute a violation, and may include the nature of any

corrective action proposed to be required.

(2) Each cease and desist and clean-up order issued pursuant to sections 4-8-10(d) and 4-8-10(e)

shall be accompanied by or have incorporated in it the notice provided for in subsection 4-810(b)(1) of this section unless such notice shall have prior thereto been given.

(1) In any notice given under section 4-8-10(b), the Department may require the alleged violator to

appear before it for a hearing and to answer each alleged violation. Such hearing shall be held no

sooner than fifteen (15) days after service of this notice, except the Department may set an earlier

date for hearing if so requested by the alleged violator or if any emergency exists. This hearing

shall be conducted in accordance with the Colville Administrative Procedures Act.

(2) If the Department does not require an alleged violator to appear for a hearing, the alleged

violator may request the hearing. Such request shall be in writing and shall be filed with the

Department no later than thirty (30) days after service of the notice under section 4-8-10(b). If

such a request is filed, a hearing shall be held within a reasonable time.

(3) If a hearing is held pursuant to the provisions of this section, it shall be recorded and this

record be made available to the public. All parties may respond to the notice served under section

4-8-10(b) and may present evidence and argument on all issues, call witnesses, and conduct crossexamination required for a full disclosure of the facts as provided for in the Colville

Administrative Procedures Act.

(d) Hearing Procedures for Alleged Violation: Upon a finding and determination, after hearing, that a

violation of a permit provision, Departmental directive or order has occurred, the Department may suspend,

modify, or revoke the pertinent permit, or take such other action with respect to the violation as may be

authorized by applicable law.

(September 2010 version of Chapter 4-8)

(e) Cease and Desist Orders: If the Department determines, with or without a hearing, that there exists a

violation of any provision of this Chapter or of any order, permit, or other requirement of this Chapter, the

Department may issue a cease and desist order. Such order shall set forth the provision alleged to be

violated, the facts alleged to constitute the violation, and the time by which acts or practices complained of

must be terminated.

(f) Clean-Up Orders: The Department may issue orders to any person to clean up material which he, or his

employee, or his agent has accidentally or purposely dumped, spilled, or otherwise deposit in or near

Reservation waters which may pollute them. The Department may also request that the Tribal attorney

proceed and take appropriate action.

(g) Restraining Orders and Injunctions: In the event any person fails to comply with either a cease and

desist order or a clean-up order which order or orders are not subject to stay pending administrative or

judicial review, the Department may request the Tribal attorney to investigate, and if appropriate, bring suit

for temporary injunction to prevent any further or continued violation of such order or orders. In any such

suit the findings of the Department based upon evidence in the record, shall be given due difference by any

reviewing administrative body or court.

(1) Emergencies shall be given precedence over all other such matters pending in Tribal Court.

The institution of such injunction proceedings by the Tribal attorney on behalf of the Department

shall confer upon such court exclusive jurisdiction to determine finally the subject matter of the

proceedings.

(h) Civil Penalties:

(1) Any person who violates any provision of any permit issued under this Chapter or any final

cease and desist order or clean-up order shall be subject to a civil penalty of not more than ten

thousand ($10,000) per day for each day during which such violation occurs.

(2) Penalty amounts shall be determined after hearing and may be collected by the Tribe by action

instituted in Tribal Court by the Tribal attorney for collection of such penalty. A stay of any order

of the Tribe pending judicial review shall not relieve any person from any liability under

subsection 4-8-10(h)(1) of this section, but the reason for the request for judicial review shall be

considered in the determination of the amount of the penalty.

(i) Falsification and Tampering: Any person who knowingly makes any false statement, representation, or

certification in any application, record, report, plan, or other document filed or required to be maintained

under this Chapter, or who falsifies, tampers with, or knowingly renders inaccurate any monitoring device

or method required to be maintained under this Chapter shall be subject to a civil penalty of not more than

five hundred dollars ($500) for each individual instance. Each day that invalid monitoring data is generated

as a result of such wrongful action shall constitute a separate violation.

(j) Proceeding by Other Parties:

(1) The factual or legal basis for proceedings or other actions that shall result from a violation of

this Chapter inure solely to the benefit of the Tribe is not intended by this Chapter, in any way, to

create new private rights or to enlarge existing private rights. A determination that water pollution

exists or that any standard has been disregarded or violated, whether or not a proceeding or action

may be brought by the Department or the Tribe, shall not create by reason thereof any presumption

of law or finding of fact which shall inure to or be for the benefit of any person other than the

Tribe.

(2) A permit issued pursuant to this Chapter may be introduced in any court of law as evidence

(September 2010 version of Chapter 4-8)

that the permittee's activity is not a public or private nuisance. Introduction into any evidence of

such permit and evidence of compliance with the permit conditions shall constitute a prima facie

case that the activity to which the permit pertains is not public or private nuisance.

4-8-11 Waiver of Regulations

Whenever a strict interpretation of this Chapter would result in extreme hardships the Department may

waive or modify such regulation or portion thereof, provided such waiver or modification is consistent with

the intent of this Chapter and no public health hazard will result.

4-8-12 Cooperation with Public Agencies—Grants and Gifts

The Department is authorized subject to approval of the Tribal Council, to accept, receive, disburse, and

administer grants or other funds or gifts from any source, for the purposes of carrying out the provisions of

this Chapter and to consult and cooperate with federal and state agencies in matters pertaining to this

Chapter. The Department is authorized to negotiate, subject to approval by the Tribal Council, intergovernmental agreements and other cooperative agreements which may create, modify, or change duties

established by this Chapter, providing that creation of new regulatory requirements or changes in existing

regulatory requirements must comply with the procedural requirements of the Colville Administrative

Procedure Act applicable to rule-making actions before such regulations become effective.

4-8-13 Statutes and Trust Responsibility Not Modified

Nothing in this Chapter as now or hereafter modified shall modify or waive any requirements to comply

with applicable federal laws and regulations. Nothing in this Chapter as now or hereafter amended shall be

construed to modify, waive or impair the trust responsibility of the United States.

4-8-14 Severability

Should any part of this Chapter be declared unconstitutional or invalid for any reason such declaration shall

not affect the validity of the remainder of this Chapter.
