New York Codes, Rules and Regulations › Title 21 - Miscellaneous › Chapter XVIII - Delaware River Basin Commission › Subchapter B - Water Quality Regulations › Part 860 - Water Quality Standards For The Delaware River Basin (article 3) › Basinwide Surface Water Quality Standards › Section 860.3 - Stream quality objectives

Current through Register Vol. 46, No. 28, July 10, 2024
(a)
Antigradation of waters.
(1)
					 Interstate waters. It is the policy of the commission to maintain the quality
					 of interstate waters, where existing quality is better than the established
					 stream quality objectives, unless it can be affirmatively demonstrated to the
					 commission that such change is justifiable as a result of necessary economic or
					 social development or to improve significantly another body of water. In
					 implementing this policy, the commission will require the highest degree of
					 waste treatment determined to be practicable. No change will be considered
					 which would be injurious to any designated present or future use.
(2) Special protection waters. It is the
					 policy of the commission that there be no measurable change in existing water
					 quality except towards natural conditions in waters considered by the
					 commission to have exceptionally high scenic, recreational, ecological, and/or
					 water supply values. Waters with exceptional values may be classified by the
					 commission as either outstanding basin waters or significant resource waters.
					 In determining waters suitable for classification as special protection waters,
					 the commission will consider nomination petitions from local, State and Federal
					 agencies and governing bodies, and the public for waters potentially meeting
					 the definition of outstanding basin waters and significant resource waters as
					 described in subparagraph (i) of this paragraph. The following policies shall
					 apply to waters classified by the commission as outstanding basin waters or
					 significant resource waters and their drainage areas:
(i) Definitions.
(a)
Outstanding basin waters
are interstate and contiguous intrastate waters that are contained within the
					 established boundaries of national parks; national wild, scenic and
					 recreational rivers systems; and/or national wildlife refuges that are
					 classified by the commission under clause (vii)(
a
) of this
					 paragraph hereof as having exceptionally high scenic, recreational, and
					 ecological values that require special protection.
(b)
Significant resource
					 waters
are interstate waters classified by the commission under clause
					 (vii)(
b
) of this paragraph hereof as having exceptionally high
					 scenic, recreational, ecological, and/or water supply uses that require special
					 protection.
(c)
Existing
					 water quality
for purposes of the Special Protection Waters Program is
					 defined for a limited set of parameters, consisting of those listed in tables 1
					 and 2. Existing water quality is defined in table 1 for stream reaches between
					 Hancock, New York and the Delaware Water Gap and in table 2 for stream reaches
					 between the Delaware Water Gap and Trenton, New Jersey. Where existing water
					 quality is not defined in tables 1 and 2, existing water quality may be defined
					 by extrapolation from the nearest upstream or downstream interstate control
					 point, from data obtained from sites within the same ecoregion, or on the basis
					 of best scientific judgement.
(d)
Measurable change to existing water quality
is defined as an
					 actual or estimated change in a seasonal or non-seasonal mean (for SPW waters
					 upstream of and including river mile 209.5*) or median (for SPW waters
					 downstream of river mile 209.5) in-stream pollutant concentration that is
					 outside the range of the two-tailed upper and lower 95 percent confidence
					 intervals that define existing water
					 quality.*
(e)
Public interest
is a
					 determination of all the positive and negative social, economic and water
					 resource impacts associated with a project affecting a significant resource
					 water. A project that is in the public interest is one that, at a minimum,
					 provides housing, employment, and/or public facilities needed to accommodate
					 the adopted future population, land use, and other goals of a community and
					 region without causing deleterious impacts on the local and regional
					 environment and economy. In general, such a project would be one that conforms
					 to a locally adopted growth management plan which is undergoing active
					 implementation by local officials, is supported by the larger community as a
					 whole, and is compatible with national, State and regional objectives as well.
					 For a project not fully meeting the above criteria, the commission will weigh
					 the positive and negative impacts to determine public interest.
(f)
Regional resources management
					 plan
is a management plan developed and adopted by the government
					 agency that is assigned primary responsibilities for the overall management of
					 a national park, scenic and recreational river and/or wildlife refuge which
					 contains waters that have been classified by the commission as outstanding
					 basin waters. A regional resources management plan is one that addresses, among
					 other subjects, the location and general size of allowable wastewater treatment
					 facilities. A regional resources management plan, or applicable portions
					 thereof, may be incorporated into the commission's comprehensive
					 plan.
(g)
Natural
					 condition
is the ecological state of a water body that represents
					 conditions without human influence.
(h)
Nondischarging/load reduction
					 options
are options whereby the amount of wastewater discharged to a
					 surface stream is reduced by (
1
) instituting load reduction
					 measures involving reductions in pollutants at the source possibly accompanied
					 by water conservation practices to reduce the amount of flow received at a
					 wastewater treatment plant; and/or (
2
) using land-based
					 wastewater disposal whereby treated wastewater effluent is further treated by
					 percolation and other soil-based processes instead of instream
					 processes.
(i)
Natural
					 wastewater treatment systems
are soil-based, vegetative and/or aquatic
					 wastewater treatment systems characterized by the use of low energy treatment
					 processes that use and simulate "natural" environmental processes such as
					 primary and secondary productivity, crop production, wetlands, ponds and
					 others.
(j)
Nonpoint
					 sources
are sources of pollutants carried by surface and subsurface
					 runoff that are derived from human activities and land use.
(k)
Cumulative impact
is the
					 net sum of all individual impacts including all point and nonpoint source
					 impacts.
(l)
Boundary
					 control points
are locations where monitoring and other activities
					 occur to determine existing water quality, no measurable change, and related
					 pollution control requirements as applicable. Boundary control points for
					 outstanding basin waters will generally correspond to federally established
					 boundaries for national parks, etc. while those for significant resource waters
					 will generally correspond to the confluence of an intrastate tributary with the
					 classified interstate water. The locations of boundary and interstate control
					 points are described in part C of table 1 for the reach between Hancock, NY and
					 the Delaware Water Gap and in tables 2A and 2B for the reach between the
					 Delaware Water Gap and Trenton, NJ.
(m)
Interstate control
					 points
are general locations used to assess water quality for purposes
					 of defining and protecting existing water quality. The locations of boundary
					 and interstate control points are described in part C of table 1 for the reach
					 between Hancock, NY and the Delaware Water Gap and in tables 2A and 2B for the
					 reach between the Delaware Water Gap and Trenton, NJ.
(n)
Growth management plans
are locally developed and adopted plans expressing the social, economic, and
					 environmental goals and objectives of the local community. A growth management
					 plan in this context can be one plan, a series of plans, local ordinances, and
					 other official documents of a municipality. Growth management plans outline the
					 community's desired growth patterns and related infrastructure. To be
					 considered in the commission's determination of public interest, growth
					 management plans must be undergoing active implementation and forming the basis
					 for local governmental decisions.
(o) An
expanding wastewater treatment
					 project
is a project involving either (1) alterations or additions to
					 an existing wastewater treatment facility that result in a reviewable project
					 in accordance with the commission's
Rules of Practice and
					 Procedure
; or (2) a new load or increased flow or loading from an
					 existing facility that was not included in a NPDES permit or docket effective
					 on the date of SPW designation.
(p)
Substantial alterations or additions
are those additions and
					 alterations resulting in:
(1) a complete
					 upgrade or modernization of an existing wastewater treatment plant, including
					 substantial replacement or rehabilitation of the existing wastewater treatment
					 plant, including substantial replacement or rehabilitation of the existing
					 wastewater treatment process or major physical structures such as headworks,
					 settling tanks, and biological/chemical treatment and filtration tanks, whether
					 conducted as a single phase or a multi-phased project or related projects;
					 or
(2) a new load or increased flow
					 or loading from an existing facility that was not included in a NPDES permit or
					 docket effective on the date of SPW designation. Among other projects,
					 modifications made solely to address wet weather flows; and alterations that
					 are limited to changes in the method of disinfection and/or the addition of
					 treatment works for nutrient removal are not deemed to be "Substantial
					 Alterations or Additions."
(q)
Load
and
Loading
are used interchangeably in these regulations and
					 refer to the amount of a substance or material, expressed as a weight per unit
					 time (pounds per day, for example), that is discharged from a
					 facility.
(r)
Incremental
					 load
and
incremental loading
are used interchangeably
					 in these regulations and refer to the load that is greater than the actual load
					 discharged by a facility at the time of SPW designation.
(s)
Best management
					 practices
are any structural or nonstructural measure designed to
					 reduce stormwater runoff and resulting nonpoint source loads.
(t)
Watershed nonpoint source
					 management plan
is a plan prepared for a watershed that describes the
					 basis for, and overall control strategy of, a plan for controlling, limiting,
					 and abating all relevant nonpoint source loadings within the watershed. The
					 plan will identify and assess important natural and anthropogenic features and
					 influences on water quality; existing local, state and other nonpoint source
					 control programs; potential nonpoint source loads on special protection waters;
					 watershed-specific protection requirements; and the institutional needs and
					 arrangements required to implement the plan.
(u)
Nonpoint source pollution control
					 plan
is a plan describing the best management practices to be used at
					 the project site and in the project service area to control increases in
					 nonpoint source pollutant loadings resulting from the project.
(v)
Priority watershed
is a
					 watershed that has been evaluated in conjunction with other watersheds draining
					 to special protection waters and designated by the commission as having a
					 substantial potential pollution impact on the water quality of special
					 protection waters in comparison with other watersheds.
(ii) No measurable change to existing water
					 quality.
(a) Outstanding basin waters shall be
					 maintained at their existing water quality. Point and nonpoint sources of
					 pollutants originating from outside the boundaries of stream reaches classified
					 as outstanding basin waters shall be treated as required and then dispersed in
					 the receiving water so that no measurable change occurs at boundary and
					 interstate control points. Point sources of pollutants discharged to
					 outstanding basin waters shall be treated as required and then dispersed in
					 such a manner that complete mixing of effluent with the receiving stream is,
					 for all practical intents and purposes, instantaneous.
(b) Significant resource waters shall not be
					 degraded below existing water quality as defined in these regulations, although
					 localized degradation of water quality may be allowed for initial dilution if
					 the commission, after consultation with the State NPDES permitting agency,
					 finds that the public interest warrants these changes. Point and nonpoint
					 sources of pollutants originating from outside the boundaries of stream reaches
					 classified as significant resource waters shall be treated as required and then
					 dispersed in the receiving water so that no measurable change occurs at
					 boundary and interstate control points, unless a mixing zone is allowed in
					 significant resource waters, and then to the extent of the mixing zone
					 designated as set forth in this section. If degradation of water quality is
					 allowed for initial dilution purposes, the commission, after consultation with
					 the State NPDES permitting agency, will designate mixing zones for each point
					 source and require the highest possible point source treatment levels necessary
					 to limit the size and extent of the mixing zones. The dimensions of the mixing
					 zone will be determined by the commission after consultation with the State
					 NPDES permitting agency based upon an evaluation of (1) site-specific
					 conditions, including channel characteristics; (2) the cost and feasibility of
					 treatment technologies; and (3) the design of the discharge structure. Mixing
					 zones will be developed using the wastewater treatment facility design
					 conditions and low ambient flow conditions unless site-specific characteristics
					 indicate otherwise. Nonpoint sources shall be subject to the requirements of
					 subparagraph (v) of this paragraph for the implementation of nonpoint source
					 control plans.
(iii)
					 Allowable discharges.
(a) Direct discharges of
					 wastewater to special protection waters are discouraged. The following
					 categories of projects discharging directly to special protection waters may be
					 approved only after the applicant demonstrates that it has fully evaluated all
					 non-discharge/load reduction alternatives and is unable to implement these
					 alternatives because of technical and/or financial infeasibility: new
					 wastewater treatment facilities and substantial alterations or additions to
					 existing wastewater treatment facilities. When evaluating non-discharge/load
					 reduction alternatives, the applicant shall consider alternatives to any and
					 all loadings-both existing and proposed-in excess of actual loadings at the
					 time of SPW designation.
(b) The
					 following categories of projects within the drainage area of special protection
					 waters may be approved only after the applicant demonstrates that it has fully
					 evaluated all natural wastewater treatment system alternatives and is unable to
					 implement these alternatives because of technical and/or financial
					 infeasibility: new wastewater treatment facilities and substantial alterations
					 or additions to existing wastewater treatment facilities. When evaluating
					 natural treatment alternatives, the applicant shall consider alternatives to
					 any and all loadings-both existing and proposed-in excess of actual loadings at
					 the time of SPW designation.
(c)
					 The following categories of projects discharging directly to significant
					 resource waters may be approved only following a determination that the project
					 is in the public interest as that term is defined in subparagraph (a)(2)(i)(e)
					 of this paragraph: new wastewater treatment facilities and substantial
					 alterations or additions to existing wastewater treatment facilities.
(d) The general number, location and size of
					 future wastewater treatment facilities discharging to outstanding basin waters
					 (if any) shall be developed taking into consideration any adopted regional
					 resource management plan as defined in clause (i)
(f)
of this
					 paragraph and, on an individual project basis, considering the feasibility of
					 non-discharge/load reduction alternatives.
(iv) Wastewater treatment facilities.
(a) All wastewater treatment facilities
					 discharging to waters classified as special protection waters shall have
					 available standby power facilities unless it can be shown that a proposed
					 discharge can be interrupted for an extended period with no threat to the water
					 quality of special protection waters. Existing facilities must comply with this
					 requirement upon their next permit renewal under the delegated national
					 polluant discharge elimination system (NPDES) permit program.
(b) All wastewater treatment facilities
					 discharging to special protection waters that are not staffed 24 hours every
					 day shall have a remote alarm that will continuously monitor plant operations
					 whenever the plant is not staffed. The alarm system will be designed to alert
					 someone available with authority and knowledge to take appropriate action.
					 Existing facilities must comply with this requirement upon their next permit
					 renewal under the delegated NPDES program.
(c) All new wastewater treatment facilities
					 discharging to outstanding basin waters shall not have visual discharge plumes.
					 Existing facilities must comply with this requirement upon their next permit
					 renewal under the delegated NPDES program.
(d) All new wastewater treatment facilities
					 discharging to special protection waters shall prepare and implement an
					 emergency management plan following the guidance provided in the Water
					 Pollution Control Federation's
Manual of Practice SM-8, Emergency
					 Planning for Municipal Wastewater Facilities,
the U.S. EPA's
Design Criteria for Mechanical, Electric and Fluid System and Component
					 Reliability
or other suitable manuals. Emergency management plans
					 shall include an emergency notification procedure covering all affected
					 downstream users. Existing facilities must comply with this requirement upon
					 their next permit renewal under the delegated NPDES program.
(e) The minimum level of wastewater treatment
					 for the following categories of projects will be "Best Demonstrable Technology"
					 as defined below: all new wastewater treatment facilities and all projects
					 involving substantial alterations or additions to existing wastewater treatment
					 facilities when the new or expanding facility discharges directly to
					 outstanding basin waters or significant resource waters. Equivalent effluent
					 criteria for industrial facilities and seasonal limits, if any, will be
					 developed on a case-by-case basis. The following 30-day average effluent
					 criteria define best demonstrable technology:*
5-day CBOD:
10 mg/l or less
Dissolved oxygen:
6.0 mg/l or greater
Total suspended solids:
10 mg/l or less
Ammonia-nitrogen:
1.5 mg/l or less
Total nitrogen:
10.0 mg/l or less
Total phosphorus:
2.0 mg/l or less
Fecal coliform:
50/100 ml or less
(f) Best demonstrable technology for
					 disinfection shall be ultraviolet light disinfection or an equivalent
					 disinfection process that results in no harm to aquatic life, does not produce
					 toxic chemical residuals, and results in effective bacterial and viral
					 destruction.
(g) For
wastewater treatment facility
discharge projects that satisfy
					 applicable requirements of subparagraphs (ii) through (iv) of this paragraph,
					 the commission may approve effluent trading on a voluntary basis between point
					 sources within the same watershed or between the same interstate or boundary
					 control points to achieve no measurable change to existing water quality.
					 Applicants seeking the commission's approval for a trade must demonstrate
					 equivalent load and pollutant reductions and the ability (through contracts,
					 docket conditions, NPDES effluent limits or other legal instruments) to ensure
					 continuous achievement of the required reductions for a term of not less than
					 five years or the time required for the point source(s) to install the
					 treatment needed to demonstrate no measurable change to existing water quality,
					 whichever term is longer. States will be encouraged to incorporate appropriate
					 conditions in the next NPDES permits issued to the trading
					 dischargers.
(h) For wastewater
					 treatment facilities within the drainage area to special protection waters, the
					 actual loads and design flows included in a NPDES permit or docket effective at
					 the time of special protection waters designation ("SPW designation") may
					 continue without triggering the additional treatment requirements and
					 alternatives analyses required by these regulations. However, when substantial
					 alterations or additions as defined herein are proposed, although the actual
					 discharge at the time of SPW designation remains exempt from additional
					 requirements, the proposed expansion cannot be approved until (1) the applicant
					 demonstrates that it has evaluated all non-discharge load reduction
					 alternatives for all or a portion of the incremental load and is unable to
					 implement these alternatives because of technical or financial infeasibility
					 (for discharges directly to outstanding basin waters [OBW] and significant
					 resource waters [SRW]); (2) the applicant demonstrates that it has evaluated
					 all natural wastewater treatment system alternatives for all or a portion of
					 the incremental load and is unable to implement these alternatives because of
					 technical or financial infeasibility (for discharges directly to OBW and SRW
					 and for tributary discharges); (3) the commission has determined that the
					 project is demonstrably in the public interest as defined herein (for
					 discharges directly to SRW); (4) the minimum level of treatment to be provided
					 for the incremental discharge is best demonstrable technology as defined herein
					 (for discharges directly to OBW and SRW); and (5) the applicant demonstrates
					 that the project will cause no measurable change to existing water quality as
					 defined herein (for discharges directly to OBW and SRW and for tributary
					 discharges).
(i) For wastewater
					 treatment facility projects subject to the no measurable change requirement,
					 the demonstration of no measurable change to existing water quality shall be
					 satisfied if the applicant demonstrates that the new or incremental increase in
					 the facility's flow or load will cause no measurable change at the relevant
					 water quality control point for the parameters denoted by asterisks in tables 1
					 and 2 of this section: ammonia (NH3N); dissolved oxygen
					 (DO); fecal coliform (FC); nitrate (NO3N) or nitrite +
					 nitrate (NO2N + NO3N); total
					 nitrogen (TN) or total kjeldahl nitrogen (TKN); total phosphorus (TP); total
					 suspended solids (TSS); and biological oxygen demand (BOD) (table 1 only). In
					 making the demonstration required in the preceding sentence the applicant shall
					 use a DRBC-approved model of the tributary or main stem watershed if available.
					 Where a DRBC-approved model is not available, the applicant shall use other
					 methodologies submitted to and approved in advance by the commission to
					 estimate cumulative effect at the applicable control point.
(v) Control of nonpoint sources.
(a) Projects subject to review under section
					 3.8 of the Compact that are
					 located in the drainage area of special protection waters must submit for
					 approval a nonpoint source pollution control plan that controls the new or
					 increased nonpoint source loads generated within the portion of the project's
					 service area which is also located within the drainage area of special
					 protection waters. The plan will document which best management practices
					 described in handbooks, manuals and other documents prepared by the applicable
					 state environmental agency that the project sponsor will use to control, to the
					 extend possible, the nonpoint source loads from the project. In approving the
					 plan, the commission may consider, but not require, tradeoffs, that the project
					 sponsor might propose, between the reduction of potential new nonpoint source
					 loads and:
(1) equivalent reductions in
					 existing nonpoint source loads;
(2)
					 equivalent point source loads; and
(3) equivalent nonpoint source loads from
					 outside the affected service area.
Applicants desiring commission approval of tradeoff
						strategies must provide information concerning the amount of nonpoint source
						loads to be reduced through an equivalent tradeoff process and, where
						necessary, the enforceable mechanisms and/or agreements required to implement
						the tradeoffs. Where tradeoffs have been approved, control measures for
						existing nonpoint sources must be substantially in-place prior to project
						operation. The executive director may, upon agreement with the State, delegate
						review and approval responsibilities under this section to the appropriate
						State environmental agency. Exceptions to this policy are:
(i) Public authorities, other special purpose
					 districts, and private corporations that do not have the legal authority to
					 implement nonpoint source controls in their new or expanded service areas. Such
					 entities are subject, however, to the requirement set forth in clause
(b)
of this subparagraph, that no new connection may be
					 approved unless the area(s) served is (are) regulated by a nonpoint source
					 pollution control plan approved by the commission.
(ii) The requirement for service area
					 nonpoint source control plans is automatically satisfied if the project service
					 area is part of a watershed nonpoint source management plan that has been
					 adopted into the commission's comprehensive plan and is being
					 implemented.
(iii) Projects located
					 above major surface water impoundments listed in subdivision (a)(2)(vii)(e) of
					 this section where time of travel and relevant hydraulic and limnological
					 factors preclude a direct impact on special protection waters.
(iv) Projects located in municipalities that
					 have adopted and are actively implementing nonpoint source/stormwater control
					 ordinances that have been reviewed and approved by the commission.
(v) Projects located in watersheds where the
					 applicable State environmental agency, county government, and local
					 municipalities are participating in the development of a watershed plan being
					 prepared under the auspices of these regulations, the Federal Clean Water Act,
					 or State initiatives.
(b) Approval of a new or expanded water
					 withdrawal and/or wastewater discharge project will be subject to the condition
					 that any new connection to the project system only serve an area(s) regulated
					 by a nonpoint source pollution control plan which has been approved by the
					 commission.
(c) Within two years
					 after the adoption of special protection waters nonpoint source control
					 regulations, the commission shall, after substantial consultation with local,
					 county, State and Federal agencies and the general public, publish a report
					 presenting its methodology for prioritizing watersheds in the special
					 protection waters drainage area including alternatives, if any; a preliminary
					 listing of priority watersheds in the drainage area; and a recommended plan of
					 study for the development of watershed-specific management plans. For waters
					 classified as special protection waters after December 1992, the watershed
					 prioritization process will be completed within two years after the special
					 protection waters are classified. Watershed priorities will be determined from
					 a comparative analysis of each watershed's location and potential, future
					 impact on existing water quality at designated boundary and interstate control
					 points. In determining priorities, the commission will consider:
(1) the physical characteristics of the
					 watershed including slopes, soils, existing land use and land cover, drainage
					 characteristics, and others;
(2)
					 the status of existing water quality and trends, if any, of the watershed as
					 measured as its boundary control point;
(3) the anticipated mass loadings of new
					 nonpoint sources;
(4) the watershed
					 management and planning priorities of applicable local, State and Federal
					 agencies;
(5) the current status of
					 local land use/nonpoint source controls in the watershed; and,
(6) the stormwater permitting activity in the
					 NPDES permitting program; and
(7)
					 other natural and anthropogenic factors.
(d) Once the public has been given an
					 opportunity to comment, the commission will adopt a list of priority
					 watersheds. This listing will be reviewed and modified as necessary on a two
					 year basis after adoption.
(e)
					 Within five years after adopting a list of priority watersheds draining to
					 special protection waters, the commission shall develop, or encourage the
					 development of, watershed nonpoint source management plans for each priority
					 watershed unless new circumstances result in deferring plan completion.
					 Watershed nonpoint source management plans will focus on nonpoint source
					 loadings, but will consider total loads including both point and nonpoint
					 sources and their interrelationship where necessary. During plan development,
					 the commission will seek technical assistance from the applicable State
					 environmental agency and all other applicable Federal, State, county, and local
					 government units; and will consider direct delegation of plan development (with
					 concurrence of the State environmental agency) to any county or other
					 applicable governmental entity desiring to perform the watershed planning
					 activities on behalf of, or instead of, the commission. Where more than one
					 political unit shares a watershed, joint plan development arrangements between
					 the commission and delegated agencies will be developed.
(f) Watershed management plans developed by
					 the commission, or approved by the commission will be incorporated into the
					 commission's comprehensive plan in accordance with the
Rules of
					 Practice and Procedure.
(g) The commission shall encourage the
					 voluntary development of watershed management plans for tributary watersheds
					 entering special protection waters and local nonpoint source regulatory
					 programs that conform to the goals and objectives of the special protection
					 waters regulations as promulgated in subdivision (a)(2) of this section. Within
					 the limits of its resources, the commission will provide technical assistance,
					 a clearinghouse for nonpoint sources information, regulatory authority,
					 inter-agency coordination, and other services to local and other governmental
					 units desiring to develop and implement stormwater and nonpoint source
					 watershed plans and local regulatory programs.
(h) The commission shall encourage the
					 submission of watershed management plans prepared voluntarily and independently
					 from these regulations for consideration of inclusion into the commission's
					 comprehensive plan.
(vi)
					 Policies regarding intergovernment responsibilities.
(a) Inter-relationship of State and
					 commission responsibilities. The applicable State environmental agency shall
					 assure to the extent possible that existing water quality in special protection
					 waters is not measurably changed by pollution discharged into the intrastate
					 tributary watersheds within its jurisdiction. For water quality management
					 purposes, the State environmental agency and the commission will jointly
					 establish boundary control points as described in subparagraph
					 (i)
(l)
and (vii)
(d)
of this paragraph. In
					 performing this responsibility, the State environmental agency shall require
					 that all new or expanding wastewater treatment facilities and existing
					 wastewater treatment plants applying for a discharge permit or permit renewal
					 under the delegated NPDES program to comply with the policies as prescribed in
					 subparagraph (iv) of this paragraph unless it can be demonstrated, after
					 consultation with the commission, that these requirements are not necessary for
					 the protection of existing water quality in the special protection waters due
					 to distance from special protection waters, time of travel, the existence of
					 water storage impoundments, the waste assimilation characteristics of the
					 receiving stream, and other relevant hydrological and limnological factors. The
					 commission shall, to the extent practicable and necessary, coordinate and
					 oversee all special protection waters activities and assist the efforts of each
					 State environmental agency to control pollutants originating from intrastate
					 tributary watersheds. The commission shall determine pollution control
					 requirements for discharges to special protection waters; for nonpoint sources
					 draining directly into special protection waters; and total nonpoint source
					 loads emanating from intrastate tributary watersheds as measured at boundary
					 control points.
(vii)
					 Classified special protection waters.
(a) The
					 following stream reaches are classified as outstanding basin waters:
(1) the Upper Delaware Scenic and
					 Recreational River (Delaware River between River Mile 330.7 and
					 258.4);
(2) those portions of
					 intrastate tributaries located within the established boundary of the Upper
					 Delaware Scenic and Recreational River Corridor;
(3) the Middle Delaware Scenic and
					 Recreational River (Delaware River between River Miles 250.1 and
					 209.5);
(4) those portions of
					 tributaries located within the established boundary of the Delaware Water Gap
					 National Recreation Area.
(b) The following stream reaches are
					 classified as significant resource waters:
(1) The Delaware River between River Miles
					 258.4 (the downstream boundary of the Upper Delaware Scenic and Recreational
					 River) and 250.1 (the upstream boundary of the Delaware Water Gap National
					 Recreation Area).
(2) The Lower
					 Delaware River between River Miles 209.5 (the downstream boundary of the
					 Delaware Water Gap National Recreation Area) and 134.34 (the Calhoun Street
					 Bridge near the Head of Tide at Trenton, NJ).
(c) Definitions of existing water quality for
					 waters classified in subclauses
(1)
and
(2)
of this clause above are presented in part A of table 1 for the Upper Delaware
					 Scenic & Recreational River and part B of table 1 for the reach from
					 Millrift, PA. to the Delaware Water Gap, including the Middle Delaware Scenic
					 and Recreational River; and in table 2 for the reach between the Delaware Water
					 Gap and Trenton, NJ.
(d) The
					 location of boundary and interstate control points are described in part C of
					 table 1 for the reach between Hancock, NY and the Delaware Water Gap and in
					 table 2 for the reach between the Delaware Water Gap and Trenton, NJ.

1The numeric values for
						existing water quality set forth in parts A, B and C of table 1 were developed
						through field measurements and laboratory analysis of data collected over a
						time period determined by the Commission to adequately reflect the natural
						range of the hydraulic and climatologic factors that affect water quality.
						Existing water quality is defined in terms of (a) an annual or seasonal mean of
						the available water quality data, (b) two-tailed upper and lower 95 percent
						confidence limits around the mean, and (c) the 10th and 90th percentiles of the
						data set from which the mean was calculated.

2The definitions of Existing
						Water Quality presented in Parts A and B of this table were developed by
						performing parametric statistical analyses using logarithmic transformation of
						available water quality data to derive normality. The numbers represent the
						anti-log of the statistical results and, thus, will differ from numbers
						generated by using non-transformed data. Means derived from log
						transformations, for example, will be lower than means derived from
						non-transformed data. The three indices used to develop the biocriteria were
						derived from specialized transformations of the original data, resulting in
						values that are normally distributed.
