Effective Date


Section 128-8.2 Watershed planning in the Croton System.

(a) Notwithstanding the prohibitions set forth in section

128-3.6 on new or expanded wastewater treatment plants with surface

discharges within the sixty day travel time to intake or within phosphorus

restricted basins, the Department shall allow for the preparation and

implementation of a Comprehensive Croton System Water Quality Protection

Plan ("Croton Plan") and an accompanying phosphorus offset program and

diversion credit program in accordance with this section 128-8.2. Section

128-8.2 is independent of, does not govern, and is not governed by, section

128-8.1.

(b)(1) At the request of Dutchess, Putnam or Westchester

County, and in partnership with Dutchess, Putnam or Westchester County, and

the municipalities located in the Croton system watershed, the Department

shall prepare or assist in the preparation of a Croton Plan only in a

participating County or Counties which:

(i) Identifies significant sources of pollution to the

Croton system;

(ii) Recommends measures to be taken by the Department, the

Counties, and the municipalities which, in conjunction with other federal,

State, local and Department water quality protection programs, will prevent

degradation to, and improve, water quality, with the long term goal of

attaining water quality standards in the Croton system; and

(iii) Recommends measures to be taken to protect the

character and special needs of communities located within the watershed.

(2) A County wishing to do so may, when joined by a

majority of municipalities located within the County's watershed, choose to

prepare the Croton Plan for the portion of the watershed located within the

County. Such Croton Plan shall be prepared in partnership with the

Department.

(3) The Croton Plan shall be developed in the manner set

forth in subdivisions (c), (d) and (e) below and may allow for new

wastewater treatment plants with a surface discharge or for the expansion

of existing wastewater treatment plants with a surface discharge, provided

the additional flow is either offset by a diversion of wastewater off of

the watershed pursuant to subparagraph (e)(4)(i), or the additional

phosphorus load is offset pursuant to subparagraph (e)(4)(ii).

(4) Any data that would benefit the Croton Planning process

that is in the possession of the Department or one of the Counties or

municipalities participating in the development of a Croton Plan shall be

shared among the participants and appropriately considered in developing a

Croton Plan.

(c) The Croton Plan shall consist of the following three

elements:

(1) Identification of water quality problems and community

character needs. Such identification shall include the following elements:

(i) An identification of growth or development projected to

occur under existing municipal zoning and master plans and allowed under

existing land use controls, other than these rules and regulations, and

including development necessary to maintain community character, public

facilities and institutions and to serve local, regional or special needs;

(ii) An identification of specific existing water quality

problem areas and specific sources of pollution to the Croton system,

including areas of existing or imminent subsurface sewage treatment system

failures, areas of concentrated point source discharges and substantial

non-point source pollution, and areas in need of streambank stabilization.

(iii) An assessment of future water quality impacts related

to growth or development identified in paragraph (i) above.

(iv) An identification of areas identified in paragraph (i)

above where site constraints may prevent the siting of new subsurface

sewage treatment systems in accordance with the requirements set forth in

these rules and regulations.

(v) An identification of areas identified in paragraph (i)

above where these rules and regulations prohibit new surface discharges

from wastewater treatment plants and site constraints prevent the siting of

a new wastewater treatment plant with a subsurface discharge.

(2) Identification of investments to correct existing water

quality problems in accordance with developed priorities. Such

identification shall include the following elements:

(i) The identified investments may include investments

(i.e., capital projects and best management practices) implemented during

the development of the Croton Plan, investments that the participating

Counties and municipalities commit to implement, and an identification of

priorities for future investments, without any commitment on the part of

the Counties and municipalities to implement such investments.

(ii) Proposed measures to address water quality problems

identified in paragraph (c)(1)(ii) above. Such measures may include

subsurface sewage treatment system maintenance, rehabilitation and

replacement programs, installation of community septic systems, the

construction of sewer extensions or new sewerage systems, stormwater

controls, and the permanent diversion of wastewater to a discharge point

outside of the watershed.

(3) Strategies for prevention of future water quality

problems and the consideration of future community character needs in

conjunction with the water quality goals of the Croton Plan. Such

strategies shall include the following:

(i) An assessment of the economic, water quality, community

character, and special needs impacts of directing growth away from areas

identified in paragraphs (c)(1)(iv) and (v) above;

(ii) An identification of the economic, water quality and

community character impacts of allowing growth within those areas

identified in paragraphs (c)(1)(i), (iv) and (v) above, if directing growth

in accordance with paragraph (c)(3)(i) above is not feasible or practical;

(iii) An identification of potential areas for the

construction of new or expanded wastewater treatment plants, as provided

for in (e) below, either under a future permanent phosphorus offset program

or utilizing the 10 percent credit provision for an implemented diversion

project and a statement of the reasoning for the selection of such

potential areas;

(iv) An identification of land use and local laws and

regulations that the participating Counties and municipalities have already

implemented and/or agree to implement in the future which are intended, in

combination with other measures in the Croton Plan, to mitigate the water

quality impacts identified in subsection (c)(1)(iii) above;

(v) With respect to future land use issues, identification

of mechanisms to ensure the improvement and protection of water quality is

taken into consideration by the local government and that the local

government agrees to use best efforts to implement such mechanisms; and

(vi) At the option of the local government, designation of

village centers as provided for in Section 128-3.9(a)(7)(i) of these rules

and regulations.

(d)(1) If a County requests, pursuant to section 128-8.2(b),

that a Croton Plan be developed within five (5) years of the effective date

of these rules and regulations, the Department, in partnership with the

participating Counties and municipalities, and in consultation with the New

York State Department of Health, shall complete a draft Croton Plan and

release such draft Croton Plan for public review and comment. If a Croton

Plan has been prepared by a County and its municipalities, the County and

municipalities, in partnership with the Department and in consultation with

the New York State Department of Health, shall complete a draft Croton Plan

within five (5) years of the effective date of these rules and regulations

and release such draft Croton Plan for public review and comment. The

Department, the participating Counties and municipalities shall consider

and respond to comments received from the public in preparing the final

Croton Plan.

(2) Within six (6) months after the release of the draft

Croton Plan, the final Croton Plan shall be agreed to by the Department and

the Counties and municipalities which participated in the preparation of

the Croton Plan, and in consultation with the New York State Department of

Health. In determining whether to agree to the Croton Plan, the Department

will consider the Croton Plan, including the level of commitments therein,

taken as a whole and consistent with subsection (d) of this section, meets

the overall goals of the Croton Plan, set forth in subsection (b) of this

section. The Department will not approve or disapprove individual

components of the Croton Plan. The Department and the participating

Counties and municipalities shall make a reasonable effort to resolve any

and all issues which preclude their agreement to the Croton Plan. The five

(5) year period referred to in paragraph (1) above, and/or the six (6)

month period referred to in this paragraph (2) may be extended by agreement

of the Department and the participating Counties and municipalities. In

addition, the participating Counties and municipalities may, at any time,

agree to discontinue the development of the Croton Plan.

(3) A failure of any participating County or municipality

to agree to the Croton Plan shall not affect the ability of another

participating County or municipality to agree to the Croton Plan and to

site new wastewater treatment plants or to expand existing wastewater

treatment plants with a surface discharge in accordance with subdivision

(e).

(4) Once the Croton Plan is agreed to by the Department and

the participating Counties and municipalities, the Croton Plan shall be

considered valid and effective. The participating Counties and

municipalities agreeing to the Croton Plan may, upon 60 days written notice

to the City, modify the Plan at any time after it has been agreed upon. If

the Croton Plan is proposed to be modified, the Department shall make a

determination within sixty (60) days of notice of the proposed

modification, whether the Croton Plan, as modified, shall continue to be

valid and effective. In making such a determination, the Department shall

consider whether the Croton Plan, as modified and taken as a whole, is

consistent with subsection (d) of this section and meets the overall goals

of the Croton Plan set forth in subsection (b) of this section. Any

approved Croton Plan remains in effect pending any determination on a

proposed modification and shall remain in effect until and unless either

the Department agrees to a modification or a local government modifies it

without the Department's approval or ceases to implement it.

(5) Any Croton Plan agreed to shall be reviewed by the

participants to the plan fifteen (15) years after the Croton Plan becomes

effective in order to determine whether the Croton Plan has met and will

continue to meet its goals, and to determine whether new goals are

appropriate.

(6) The Counties and the municipalities agreeing to the

Croton Plan shall submit to the Department an annual report each year the

Croton Plan is in effect. The annual report shall be submitted on the

anniversary of the date the Croton Plan became effective and shall include:

(i) A statement of the status of the development or

implementation of measures proposed in the Croton Plan;

(ii) A statement of expenditures incurred by the Counties

and municipalities in implementing, and administering measures proposed in

the Croton Plan; and

(iii) An identification of the financial, personnel and

other resources needed to continue implementation and administration of the

measures proposed in the Croton Plan.

(e) The Croton Plan may allow for the siting of a new

wastewater treatment plant with a surface discharge or the expansion of an

existing wastewater treatment plant with a surface discharge in the Croton

System within a phosphorus restricted basin or a basin located within the

60 day travel time, but not within a coliform restricted basin, pursuant to

the following conditions:

(1) Site constraints prevent the proposed new wastewater

treatment plant or the expanded existing wastewater treatment plant from

discharging subsurface;

(2) The municipal government and the County in which the

wastewater treatment plant would be sited, confirms in writing that the

proposed new wastewater treatment plant or the expansion of an existing

wastewater treatment plant is consistent with the Croton Plan;

(3) The Department, in consultation with the New York State

Department of Health, determines that the proposed new wastewater treatment

plant or expansion of an existing wastewater treatment plant is consistent

with the water quality objectives of the Croton Plan; and

(4) The discharge from the new wastewater treatment plant

or the expansion of an existing wastewater treatment plant complies with

one of the following conditions:

(i) The total volume (or flow) of surface discharge from

such new wastewater treatment plant or expansion of an existing wastewater

treatment plant, together with the total volume of surface discharges from

all other new wastewater treatment plants and expansions of wastewater

treatment plants which have been permitted in the subject County pursuant

to this subparagraph (i), shall not, in the aggregate, exceed 10 percent of

the total volume (or flow) of surface discharge from wastewater treatment

plants located in the Croton system, within the subject County, which

previously discharged into the Croton System but have been permanently

diverted, since the effective date of these rules and regulations, to a

discharge point outside of the Watershed. The Department may approve

applications to construct new wastewater treatment plants with surface

discharges pursuant to this subdivision prior to the permanent diversion of

wastewater, and allow construction to begin on such new wastewater

treatment plants, provided that the wastewater treatment plant may not

commence operation until the diversion for which the credit is received has

actually occurred; or

(ii) In phosphorus restricted basins located outside of the

sixty day travel time, provided that the Department has determined pursuant

to section 128-8.4, based upon the results of the pilot programs set forth

in sections 128-8.2(g) and 128-8.3(a), or of other studies conducted within

the watershed, that the phosphorus offsets sought by the pilot programs

have been achieved, the Department may require that each one (1) kilogram

of projected increase in the phosphorus load resulting from the proposed

new wastewater treatment plant, together with any accompanying nonpoint

source runoff, is actually offset by at least three (3) kilograms of

reductions in phosphorus loading within the basin within which the proposed

project is located, including reductions from measures identified in and

implemented in accordance with the Croton Plan pursuant to paragraph (c)(8)

above, and otherwise eligible for an offset hereunder, whether the source

of the offsets is in the same basin or within an upstream, hydrologically

connected phosphorus restricted basin.

(5) With respect to any new or expanded wastewater

treatment plant allowed pursuant to this subdivision (e), the Department

will not impose additional requirements on the siting of such new or

expanded wastewater treatment plant other than the requirements

specifically set forth in these rules and regulations applicable to all

wastewater treatment plants, the requirements of this subdivision (e), and,

with respect to new or expanded wastewater treatment plants in phosphorus

restricted basins relying on phosphorus offsets, the requirements of any

phosphorus offset program pursuant to sections 128-8.2(g), 128-8.3(a) and

128-8.4.

(f)(1) A County or municipality wishing to participate in

the preparation of the Croton Plan shall indicate its intention to

participate by written notice to the Department given within one year of

the effective date of these rules and regulations. Such notice shall

include a commitment by the subject County or municipality to cooperate

with the Department in generating and analyzing the data and information

reasonably necessary to address the Croton Plan elements identified in

subdivision (c) above, and an agreement to minimize the use of offsets as a

basis for new wastewater treatment plants or expansions of existing

wastewater treatment plants pursuant to subdivision (e), to the extent that

the economic and social needs of such County or municipality can be

reasonably addressed without the use of such offsets.

(2) Within thirty (30) days after receipt of a notice as

described in subdivision (f)(1) above, the Department shall notify a County

or municipality of its inclusion in the preparation of a Croton Plan.

(3) If a County and its municipalities wish to prepare a

Croton Plan, in accordance with subdivision (b)(2) above, the Department

shall, within thirty (30) days of receipt of a notice as described in

subdivision (f)(1) above, authorize the County and municipalities to begin

preparation of such a Croton Plan. Such authorization shall include a

commitment by the Department to cooperate with the County and

municipalities in generating the data and information reasonably necessary

to address the Croton Plan elements identified in subdivision (c) above.

(4) The provisions of subdivision (e) above shall not apply

in any County or municipality which fails to participate in the preparation

of the Croton Plan, fails to cooperate with the Department in the manner

described in paragraph (f)(1) above in preparing the Croton Plan; fails or

ceases to implement any water quality protection measures which such County

or municipality has committed to implement as part of the final Croton Plan

agreed upon by the County, municipality and the Department; or where a

previously agreed upon Croton Plan is no longer valid and effective.

(g) In Putnam County, provided that Putnam County has

committed in writing to participate in the development of the Croton Plan

pursuant to subdivision (d) above, the Department shall allow for a pilot

program to evaluate the effectiveness of phosphorus offsets as a potential

basis for allowing construction of new wastewater treatment plants within

phosphorus restricted basins in the Croton system. Such pilot program

shall be limited to a term of five (5) years, commencing on the effective

date of these rules and regulations and expiring on the fifth anniversary

thereof. During the term of the pilot program, the Department may approve

within a Putnam County municipality which has committed in writing to

participate in development of the Croton Plan, the construction of a new

wastewater treatment plant with a surface discharge within a phosphorus

restricted basin in the Croton system provided that the following

conditions are met:

(1) The applicant proposing a new wastewater treatment

plant demonstrates that the County or municipality agrees to the plant s

inclusion in the pilot program;

(2) The applicant demonstrates, and commits to take action

to insure, that for every one (1) kilogram of projected increase in the

phosphorus load resulting from the new wastewater treatment plant and

accompanying non-point source runoff, there will be an offset which

achieves at least three (3) kilograms of reduction in phosphorus within the

basin in which the new wastewater treatment plant is located, whether the

source of the offset is in the same basin or within an upstream

hydrologically connected phosphorus restricted basin;

(3) All new wastewater treatment plants proposed to be

constructed pursuant to this pilot program shall be reviewed and approved

by the Department in accordance with section 128-3.6 of these rules and

regulations;

(4) No more than three (3) wastewater treatment plants with

surface discharges may be located in the Croton system in Putnam County

pursuant to this pilot program. The total capacity, as constructed, for

the three (3) proposed wastewater treatment plants shall not exceed a

maximum of 150,000 gpd aggregate surface discharge; and

(5) Any wastewater treatment plant constructed pursuant to

this pilot program shall be designed and operated to meet a total

phosphorus effluent limit of .2 mg/l.

(h) Nothing in this subpart is intended to constrain, limit

or preclude an applicant from seeking, or the Department from issuing,

approval of or a variance for a proposed regulated activity under any other

applicable provision of these rules and regulations.

(i) Nothing in this section or in the Croton Plan is

intended to constrain or limit the authority of local governments under

State law to make local land use and zoning decisions, and nothing in this

section or the Croton Plan should be construed to have the effect of

transferring such local land use and zoning authority from the

participating local governments to the Department or any other entity.
