New York Codes, Rules and Regulations › Title 6 - DEPARTMENT OF ENVIRONMENTAL CONSERVATION › Chapter X - DIVISION OF WATER RESOURCES › Subchapter A - GENERAL › Article 1 - MISCELLANEOUS RULES › Part 649 - NEW YORK STATE WATER POLLUTION CONTROL REVOLVING FUND REGULATIONS › Section 649.13 - Priority ranking system scoring criteria

Current through Register Vol. 46, No. 28, July 10, 2024
The numerical scores in the priority ranking system for
						project categories A, B, C, D and E are based on the following criteria:
A. Existing source.
B. Water quality improvement.
C. Consistency with management
					 plans.
D. Intergovernmental
					 needs.
E. Financial need (municipal
					 projects only).
F. Economic
					 need.
The total numerical score for the project being scored
						shall be the sum of the scores for criteria A, B, C, D, E and F for municipal
						projects and criteria A, B, C, D and F for non-municipal projects. Project
						category G projects will be selected based upon criteria set forth in the
						IUP.
The project score will be based on information in the
						approvable facilities plan or engineering report. Projects without approvable
						facilities plans or engineering reports will be scored based on information
						from other sources and adjusted when a facilities plan or engineering report is
						determined to be approvable. Projects must be adequately supported by technical
						documentation, data, reports, etc.
A.
Existing source criterion.
The project receives a score based
					 on whichever of the factors (1-5) listed below best describes the source of
					 pollution associated with the impairment of use scored under criterion B which
					 may be resolved by the project.
Factor
1.
A critical source of pollution a. A raw, partially
								  treated or intermittent point or non point source causing or significantly
								  contributing to a priority water problem which has been identified on priority
								  waterbodies list (PWL) as "precluded" or "impaired" or is resulting in
								  documented use impairment of surface and/or groundwater quality equivalent to
								  "precluded" or "impaired", or b. A source from which bioaccumulative chemicals
								  of concern (BCCs) would be reduced or eliminated.
50
2.
A significant source of pollution A raw, partially
								  treated or intermittent point or nonpoint source causing or significantly
								  contributing to a priority water problem which has been identified on priority
								  waterbodies list (PWL) as "stressed" or "threatened" or causing a documented
								  use impairment of surface and/or groundwater quality equivalent to "stressed"
								  or "threatened".
25
3.
A potential source of pollution a. A point or
								  nonpoint source causing or significantly contributing to a water use impairment
								  that is not identified on the priority waterbodies list (PWL) nor causing a
								  documented use impairment of surface water or groundwater quality, or b. A
								  point or nonpoint source project necessary to maintain or protect existing
								  facilities, conditions or water quality.
10
4.
Other A point or non point source project that was
								  necessary to preserve, protect and/or improve surface and/or groundwater
								  quality from a source of pollution identified in 1, 2, or 3 above and which
								  construction was complete as defined in section
								  649.2(a)(9)  of
								  this Part prior to being listed in a final IUP.
5
5.
None of the above.

B.
Water quality improvement
					 criterion (WQIC).
The WQIC is determined by the following three
					 factors:
1) classification points factor
					 (CPF);
2) impairment factor (IF);
					 and
3) potential improvement factor
					 (PIF). Based on the existing source identified for criterion A, points are
					 allotted to a project on the basis of the State-assigned classification of the
					 receiving water at the point of discharge, or where higher, the classification
					 of downstream surface waters, the use of which is impacted or potentially
					 impacted by the existing discharge. The points are modified depending upon the
					 severity of impairment of the desired best usage of the receiving water and the
					 potential for the proposed project to improve water quality.
The WQIC is calculated using the following equation: WQIC
						= CPF × IF × PIF
1.
Classification points factor (CPF).
Points are allotted to a
					 project on the basis of State-assigned classification of the receiving water at
					 the point of discharge, or where higher, the classification of downstream
					 surface waters, the use of which is impacted or potentially impacted by the
					 existing discharge.
Classification

AA, SA, GA (primary water supply acquifer), AA

2
Impairment of resources which have important
								  environmental quality impacts such as odor, sludge disposal, sewer maintenance
								  equipment, etc. or for a project which received a score under Existing Source
								  Criterion, Factor 4.
No resource is impaired.

1 (T) and (TS) indicate the
						application of standards to protect trout and trout spawning,
						respectively.
2 Classification C without (T)
						or (TS) appended.
2.
Impairment factor (IF).
Points are allotted to a project based
					 on the severity of impairment of the desired best usage of the affected surface
					 water or groundwater caused by the existing discharge, as indicated in the
					 priority waterbodies list (PWL), or verifiable documentation of the surface
					 water and/or groundwater impairment.
Impairment
Definition
Points
Precluded
A use is not possible (
i.e.,
frequent/persistent water quality or quantity conditions prevents all aspects
								  of the waterbody use).
6
Impaired
A use cannot be fully met (
i.e.,
occasional water quality or quantity conditions periodically prevent or
								  discourage the use of the waterbody).
4
Stressed
A water quality problem is evident, but impairment
								  is not clearly demonstrated (
i.e.,
waterbody uses are not
								  significantly limited or restricted, but occasional water quality or quantity
								  conditions periodically discourage the use of the waterbody).
2
Threatened or None
There is a threat to future water quality but no
								  existing evidence of impairment (
i.e.,
water quality currently
								  supports waterbody uses, however, existing or changed land use patterns may
								  result in restricted use) or if a project maintained or protected water quality
								  and was complete as defined in section
								  649.2(a)(9)  of
								  this Part prior to being listed in a final IUP.

3.
Potential Improvement Factor
					 (PIF).
Points are allotted to the project based on the potential for
					 the project to improve water quality.
Factor
Points
1. Degree of impairment reduced by three levels
								  (
i.e.,
from "Precluded" to "Threatened or None").

2. Degree of impairment reduced by two levels
								  (
i.e.,
from "Precluded" to "Stressed" or from "Impaired" to
								  "Threatened or None").

3. Degree of impairment reduced by one level
								  (
i.e.,
from "Precluded" to "Impaired", from "Impaired" to
								  "Stressed", or from "Stressed" to "Threatened or "None").
