4-8-1 Findings.

(a) The Colville Confederated Tribes 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.

(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.

(c) The Colville Confederated Tribes have jurisdiction to enforce Tribal Water Quality Standards in order to protect the economy, health, safety and welfare of the Reservation community.

4-8-2 Territory Covered.

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

 

(c) Waste discharge permits will not be issued which would allow violations of Tribal Water Quality 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 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 7-day, 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 mortalities 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 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 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 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 wast 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).

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.

(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.

 

1. 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.

2. 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 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, inter-governmental 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 Statues 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.
