SUBCHAPTER II ANTIDEGRADATION POLICY AND IMPLEMENTATION PLAN

Section 201 Antidegradation Policy

A Existing water uses and the level of water quality necessary to protect existing water uses

shall be maintained and protected

B Where existing water quality exceeds levels necessary to support existing uses including

but not limited to the protection and propagation of fish shellfish and wildlife and recreation in

and on the water that water quality shall be maintained and protected unless the Nation finds

after full interagency coordination and public participation that a lower level of water quality is

required in order to accommodate important economic or social development in the area of the

water in question In allowing such degradation of water quality the Nation shall nevertheless

ensure water quality adequate to protect existing uses fully

C The Nation shall mandate the highest statutory and regulatory requirements for all new

and existing point sources and the most cost effective and reasonable best management practices

for control of nonpoint source pollution

D Where high quality waters constitute an exceptional recreational cultural or ecological

resource of the Nation those waters may be designated as Outstanding Tribal Resource Waters

The existing water quality of Outstanding Tribal Resource Waters shall be fully maintained and

protected and no permanent degradation of such water quality shall be permitted for any reason

E This antidegradation policy includes protection against water quality impairment

associated with thermal discharges and it shall be implemented consistent with CWA 316 33

U S C 1326 as amended

Section 202 Implementation

A The Water Resources Program shall implement these Standards including the

antidegradation policy by establishing and maintaining controls on the introduction of pollutants

into Penobscot Waters and by taking the actions listed below in coordination with federal tribal

and state agencies as appropriate

1 Review the adequacy of existing data on Penobscot Waters including their

quality and designated uses as well as on any activities that may detrimentally

impact those waters and uses and obtain additional data where required

2 Monitor water quality to assess the effectiveness of pollution controls and to

determine whether designated uses are being supported and water quality

standards are being attained

EPA004504
3 Obtain and assess information on the impact of effluents on receiving waters

including the capability of receiving waters to support designated uses and

achieve these PWQS

4 Advise prospective dischargers of discharge requirements and coordinate with

the appropriate permitting agencies as to the same

5 Require the highest and best degree of wastewater treatment practicable

commensurate with protecting and maintaining designated uses and existing water

quality

6 Develop water quality based effluent limitations and provide comment on

technology based effluent limitations as appropriate for inclusion in any permit

issued to a discharger pursuant to CWA 402 33 U S C 1342 as amended

7 Require that effluent limitations or other appropriate limitations applicable to

activities with the potential to discharge into Penobscot Waters be included in any

permit as a condition for certification by the Nation pursuant to CWA 401 33

U S C 1341 as amended

8 Coordinate water pollution control activities with other local tribal state and

federal agencies as appropriate

9 Develop and pursue inspection programs to ensure that dischargers comply with

the requirements of these Standards and to support the enforcement of federal

permits issued by the U S Environmental Protection Agency or the U S Army

Corps of Engineers

10 Provide technical assistance to wastewater treatment facility operators

11 Publish results of water quality investigations and interpretation of those results

11 Encourage in conjunction with other agencies implementation of best

management practices to control nonpoint sources of pollution and so to support

designated uses and meet these PWQS

12 Examine existing and future Penobscot Nation policies pertaining to septic

systems solid waste disposal and other relevant activities to ensure that these

policies are consistent with meeting these PWQS

13 Determine whether in stream flows and water levels are adequate to support

designated uses and to meet these PWQS

14 Conduct an antidegradation analysis for regulated actions that may impair water

quality and

EPA004505
15 Implement specific policies and procedures to protect designated Outstanding

Tribal Resource Waters

B In the event that water quality monitoring identifies water bodies where attainable quality

is less than designated uses these Standards may be revised to reflect actual attainability for

those water bodies subject to the provisions of the Clean Water Act and consistent with the use

attainability analysis described in 40 C F R 131 10 g as may be revised from time to time

However high water temperatures caused by unusually high ambient air temperatures are not

violations of these standards

B In a stream the introduction of heat by other than natural causes shall not increase the

temperature as measured upstream from the point of introduction by more than 2 7 C 5 F

based on the weekly average of the maximum daily temperatures measured at mid depth or three

feet whichever is less

C In no event shall any discharge cause the receiving water to exceed a weekly average

temperature of 66 F or a daily maximum temperature of 73 F When the ambient temperature

of the stream naturally exceeds the limits set forth in this section no discharge alone or

combined with others shall cause the in stream temperature increase to exceed 0 5 F above the

receiving water temperature

Section 303 Minerals

The existing mineral content of Penobscot Waters shall not be altered by municipal

industrial or in stream activities or other waste discharges so as to interfere with their designated

uses Generally increases exceeding one third over naturally occurring levels will not be

allowed

Section 304 Radioactive Materials

Concentrations of radioactive constituents shall not exceed USEPA Safe Drinking Water

Act SDWA standards except when concentrations caused by naturally occurring materials

exceed those standards in which case the latter concentrations shall apply Notwithstanding the

foregoing sentence if a standard more stringent than the SDWA standard is indicated for a

designated use the more stringent standard will apply for that designated use

Section 305 Determining Compliance with Narrative Standards

Biomonitoring testing following current EPA test methods shall be used to determine

compliance with the narrative criteria in 301 through 303 provided that adequate funding is

available These protocols can be found in the publication Short Term Methods for Estimating

the Chronic Toxicity of Effluents and Receiving Waters to Freshwater Organisms 4th Ed

EPA004508
October 2002 EPA No 821 R 02 013 or the most current edition Additionally the Nation

will rely on the following references

Section 306 Biological Criteria

A All Penobscot Waters shall be of sufficient quality to support aquatic species without

detrimental changes in the resident biological communities

B The Nation s goal is that all Penobscot Waters will be free from substances whether

attributable to point source discharges nonpoint sources or in stream activities in

concentrations or combinations which impair the structure or limit the function of the resident

aquatic community as it naturally occurs

C The structure and function of the resident aquatic community shall be measured by

biological assessment methods approved by the Program Manager which may include Maine

DEP Chapter 579 Classification Attainment Evaluation Using Biological Criteria for Rivers and

Streams

D Determination of impairment or limitation of the resident aquatic community shall be

based on a compariso with the aquatic community found at an appropriate reference site or

region

Section 307 Mixing Zones

A A mixing zone is a defined and limited part of a water body adjacent to a point source of

pollution in which initial dilution of wastewater occurs and in which certain numeric water

quality standards may be exceeded provided that all the following requirements are met

1 Mixing zones shall be limited to perennial streams

2 All mixing zones shall have defined boundaries beyond which applicable water

quality standards shall be met

3 In no instance shall the narrative water quality standards in 301 be violated

EPA004509
4 In no instance shall the concentration of any toxic pollutant exceed the aquatic

habitat acute numeric standard for that pollutant The aquatic habitat acute

numeric standard for all toxic pollutants shall be met at the point of discharge

5 In perennial streams a continuous zone of passage around a mixing zone shall be

maintained in which all applicable water quality standards are met and which

provides for migration of aquatic life without exposure to pollutant concentrations

that exceed chronic toxicity for aquatic habitat numeric standards The mixing

zone shall be no larger than 25 of the cross sectional area or volume of low

flow and no wider than 50 of stream width

Section 404 Application and Construction

A The criteria assigned to a water body are those required to sustain all designated uses of

the water body and with regard to bacteria the water body class When a Penobscot Water has

more than one designated use as listed in Table 1 the applicable numeric standards for each

parameter shall be those necessary to maintain all the designated uses of that water body that is

the most stringent of those established for that body of water taking into consideration its water

body class in the case of Primary Human Contact Cultural and Ceremonial designated use

B The criteria specific to a designated use shall be maintained at all times for narrative

criteria and for persistent bioaccumulative toxic pollutants including those listed in 307 A 6

and at all times for all other pollutants except when flows are below critical low flow rates For

human health criteria the critical low flow rate is the harmonic mean flow or for ephemeral

waters the modified harmonic mean For aquatic life the critical low flow for acute criteria is

1Q10 and for chronic criteria is 7Q10 For all other numeric criteria the critical low flow is

7Q10

Harmonic mean flow is the number of daily flow measurements divided by the sum of the

reciprocals of the flows that is it is the reciprocal of the mean of reciprocals Modified

harmonic mean is based upon the nonzero flow intervals and modified by including a factor to

adjust for the proportion of intervals with zero flow The equations are as follows

Harmonic Mean

EPA004520
and Q flow value

Modified Harmonic Mean

where Qi nonzero flow

Nt total number of flow values

And N0 number of zero flow values

C Water quality standards established for the attainment and maintenance of upstream

designated uses shall be sufficient to protect the attainment and maintenance of downstream

designated uses

D These PWQS provide the basis for managing discharges attributable to point and

nonpoint sources of pollution including in stream activities These PWQS are not used to

control natural background phenomena

Section 405 Additional Numeric Water Quality Criteria

Tables listing additional numeric water quality criteria may be found in Appendices I

through IV of these Standards

SUBCHAPTER V SAMPLING AND ANALYSIS VARIANCES AND EXCEEDANCES

Section 501 Sampling and Analysis

Sample collection preservation and analysis used to determine water quality and to

maintain these Standards shall be performed in accordance with the Penobscot Nation s Quality

Assurance Plan and procedures prescribed by the latest EPA analytical references including but

not limited to the latest editions of any of the following authorities

1 American Public Health Association Standard Methods for the Examination of

Water and Wastewater 22nd Ed 2012 or the most current edition

2 EPA Methods for Chemical Analysis of Water and Wastes 3rd Ed March

EPA004521
Section 502 Variances

A The Director with the approval of the Penobscot Nation Chief and Tribal Council and of

EPA pursuant to subsection H of this section may grant a variance from a water quality

standard for a point source discharge provided that the discharger demonstrates that treatment

more advanced than that required to comply with technology based effluent limitations is

necessary to comply with the water quality standard and

1 It is not technically feasible to achieve compliance within the next three years or

2 The cost of treatment would result in substantial and widespread economic and

social impact

B A variance may be granted on a pollutan tspecific basis only A point source discharge is

required to comply with all other applicable PWQS for which a variance is not granted No

variances may be granted for point source discharges to Outstanding Tribal Resource Waters

C A variance applies only to a specific point source discharge The granting of a variance

does not modify a water quality standard Other point source dischargers to the water body shall

comply with all applicable Standards including any Standard for which a variance has been

granted for a specific point source discharge

D A variance is for a fixed term not to exceed three years Variances are not renewable but

upon adequate justification may be reissued by the Director with the approval of the Penobscot

Nation Chief and Tribal Council and of EPA pursuant to subsection H of this section In

addition the Director shall reevaluate a variance upon the issuance reissuance or modification

of the discharge permitfor the point source discharge

E A person who seeks a variance from a water quality standard shall submit a letter to the

Director requesting a variance The request shall include the following information

1 Identification of the specific pollutant and water quality standard for which the

variance is sought

2 Identification of the receiving water

3 For an existing point source discharge a detailed description of the existing

discharge control technologies that are used to achieve compliance with

applicable water quality standards For a new point source discharge a detailed

description of the proposed discharge control technologies that will be used to

achieve compliance with applicable water quality standards

4 Documentation that the existing or proposed discharge control technologies will

comply with applicable technology based effluent limitations and that more

EPA004522
advanced treatment technology is necessary to achieve compliance with the water

quality standard for which a variance is sought

5 A detailed discussion of why compliance with the water quality standard cannot

be achieved

6 A detailed discussion of the discharge control technologies that are available for

achieving compliance with the water quality standard for which a variance is

sought

7 Documentation of one or both of the following

a That it is not technically feasible to install and operate any of the available

discharge control technologies to achieve compliance with the water

quality standard for which a variance is sought or

b That installation and operation of each of the available discharge

technologies to achieve compliance with the water quality standard would

result in substantial and widespread economic and social impact

8 Documentation that the point source discharger has reduced to the maximum

extent practicable the discharge of the pollutant for which a variance is sought

through implementation of pretreatment source reduction or a waste

minimizationprogram

9 A detailed description of proposed interim discharge limitations that represent the

highest level of treatment achievable by the point source discharge during the

term of the variance Interim discharge limitations shall not be less stringent than

technology based effluent limitations

F In determining whether to recommend to the Penobscot Nation Chief and Tribal Council

to grant or deny the request for a variance the Director shall consider the following factors

bioaccumulation bioconcentration predicted exposure on biota and the likelihood that resident

biota will be adversely affected the known or predicted safe exposure levels for the pollutant of

concern and the likelihood of adverse human health effects

G The Director shall issue public notice and shall provide an opportunity for a public

hearing on whether the request for a variance should be granted or denied pursuant to the

procedures in 105 B

H A variance is subject to review and approval by the Penobscot Nation Chief and Tribal

Council and the EPA

I The final decision on a request for a variance is subject to judicial review pursuant to

Section 105 C

EPA004523
Section 503 Compliance Schedules

The Penobscot Nation Chief and Tribal Council may allow on a case by case basis

inclusion of a compliance schedule in a National Pollutant Discharge Elimination System

NPDES permit that is issued to an existing facility if it is determined by the permitting

authority that more time is required to meet the NPDES permit requirements based on new or

revised water quality standards The compliance schedule shall require compliance at the earliest

practicable time and shall specify milestones and their anticipated dates in order to track a

permittee s progress towards compliance Notwithstanding the forgoing a compliance schedule

shall not be issued for NPDES permit requirements designed to meet water quality standards for

Outstanding Tribal Resource Waters

Comment DK2

A This criterion is based on carcinogenicity of 10 6 risk Alternate risk levels may be obtained by

EPA004538
moving the decimal point e g for a risk level of 10 5 move the decimal point in the recommended

criterion one place to the right

B This water quality criterion for arsenic refers to the inorganic form only

C A more stringent Maximum Contaminant Level MCL has been issued by EPA under the Safe

Drinking Water Act See Appendix IV for a listing of the EPA MCLs

D This water quality criterion is expressed as total cyanide

E This criterion applies to total PCBs e g the sum of all congener or all isomeror homolog or Aroclor

analyses

F This criterion is based on a consumption rate of 286 grams of organisms per day derived from the

Wabanaki Traditional Cultural Lifeways Exposure Scenario 2009 Resident fish and Aquatic life from

Inland Non Anadromous diet
