A. PRIORITY POINT TOTAL
1. A priority number total for a project will
be determined by adding the priority points from each of the four priority
categories. Total Priority Points = Project Need for Reduction of Water
Pollution + Potential for Improvement Factor + Existing Population Affected +
Special Consideration. If two or more projects receive an equal number of
priority points, such ties shall be broken using the following criteria:
a. The projects shall be ranked in order of
the highest "Need for Reduction of Water Pollution."
b. If the tie cannot be broken on the basis
of need, the projects shall be ranked in order of the "Potential for
Improvement Factor."
c. If the tie
cannot be broken on the basis of the above, the project serving the greatest
population will be given priority.
B. PROJECT NEED FOR REDUCTION OF WATER
POLLUTION
All projects receive the highest applicable point level
only.
1. A documented existing
substantial health hazard will be eliminated by the project. This may include:
(1) discharge of inadequately treated wastewater to an area of immediate public
contact where inadequate operation and maintenance is not the primary cause of
the condition; (2) an area where a substantial number of failing subsurface
disposal systems are causing surfacing sewage in areas of human habitation. The
elimination of existing substantial health hazards is of highest priority. The
determination of the existence of substantial health hazards shall be based
upon the investigation, report, and certification of the local health
department and the State Division of Water Quality. Such reports and
certifications will be forwarded to EPA with the Priority List. The health
hazard designation will normally apply to unsewered communities experiencing
widespread septic tank failures and surfacing sewage: 70 points.
2. A raw sewage discharge will be eliminated
or prevented: 60 points.
3. The
surface water quality standards identified in R317-2 are impaired by an
existing discharge. For points to be allotted under this criterion the affected
stream segment must be "water quality limited" according to a wasteload
analysis and water quality standards. Water quality standards have been
established for the waters of Utah according to designated beneficial use
classifications. A stream segment is considered to be "water quality limited"
if a higher level of treatment than that which is provided by state effluent
limitations is required to meet water quality standards. A stream segment is
"effluent limited" if water quality standards are met by state imposed effluent
limitations: 50 points.
4. The
ground water quality standards identified in R317-6 are impaired by an existing
discharge. For points to be allotted under this criterion the affected ground
water must be impaired according to the numerical criteria outlined in the
ground water protection levels established for Class I and II aquifers: 50
points.
5. Construction is needed
to provide secondary treatment, or to meet the requirements of a Utah Pollution
Discharge Elimination System (UPDES) Permit or Ground Water Discharge Permit,
or the Federal Sludge Disposal Requirements: 50 points.
6. Documented water quality degradation is
occurring, attributable to failing individual subsurface disposal systems where
inadequate operation and maintenance is not the primary cause of the condition:
45 points.
7. Areas not qualifying
as an existing substantial health hazard, but where it is evident that
inadequate on-site conditions have resulted in the chronic failure of a
significant number of individual subsurface disposal systems, causing an
ongoing threat to public health or the environment. Points may be awarded in
this category only when the Division of Water Quality determines that existing
on-site limitations cannot be overcome through the use of approved subsurface
disposal practices, or that the cost of upgrading or replacing failed systems
to meet the minimum requirements of the local health department are determined
to be excessive: 45 points.
8.
Treatment plant loading has reached or exceeded 95 percent of design
requirements needed to meet conditions of an UPDES Permit or needed to restore
designated water use, or design requirements are projected to be exceeded
within 5 years by the Division of Water Quality. Points will not be allocated
under this criterion where excessive infiltration or inflow is the primary
cause for the loading to the system to be at 95 percent or greater of design
requirements: 40 points.
9.
Existing facilities that do not meet the design requirements in R317-3. Points
may be allocated under this category only if the design requirements that are
not being met are determined to be fundamental to the ability of the facility
to meet water quality standards: 40 points.
10. Interceptor sewers, collection systems,
pump stations and treatment, where applicable, are needed to solve existing
pollution, ground water, or public health concerns: 35 points.
a. Points may be awarded under this category
only if they will primarily serve established residential areas and only if
they are needed to solve existing pollution or public health
problems.
b. Points shall not be
awarded under this category where an interceptor is proposed for newly
developing recreational communities, resorts, or unincorporated
subdivisions.
c. Points may be
awarded under this category when the majority of existing septic systems are
located in defined well head protection zones or principal ground water
recharge areas to Class I and II aquifers.
11. Interceptor sewers, collection systems,
pump stations and treatment, where applicable, are needed to accomplish
regionalization or eliminate existing treatment facilities. Points shall not be
awarded under this category where an interceptor is proposed for newly
developing recreational communities, resorts, or unincorporated subdivisions:
25 points.
12. Communities having
future needs for wastewater facilities construction at existing wastewater
systems, not included above, which are consistent with the goals of the Federal
Water Pollution Control Act: 10 points.
13. Communities having future needs for new
treatment plants and interceptors, not included above, which are consistent
with the goals of the Federal Water Pollution Control Act: 5 points.
C. POTENTIAL FOR IMPROVEMENT
FACTOR (PIF)
The PIF priority point sub-total is obtained by adding the
points obtained in each of the four subcategories. Total PIF points =
Classified Water Use + Discharge Standard Factor + Restoration from Water
Quality Standard Violation + Estimated Improvement.
1. Classified Water Use. Priority points
under this subcategory are allotted in accordance with segment designations
listed in
R317-2-13,
Classifications of Waters of the State. Points are cumulative for segments
classified for more than one beneficial use.
a. Protected as a raw water source of
culinary water supply;
R317-2-13
Use Classes: 1A, 1B, or 1C: 4 points.
b. Protected for primary contact recreation
(swimming);
R317-2-13:
2A: 4 points.
c. Protected for
secondary contact recreation (water skiing, boating and similar uses);
R317-2-13:
2B: 3 points.
d. Protected for cold
water species of game fish and other cold water aquatic life, including the
necessary aquatic organisms in their food chain;
R317-2-13:
3A: 3 points.
e. Protected for warm
water species of game fish and other warm water aquatic life, including the
necessary aquatic organisms in the food chain;
R317-2-13:
3B: 3 points.
f. Protected for
non-game fish and other aquatic life, including the necessary aquatic organisms
in their food chain;
R317-2-13:
3C: 2 points.
g. Protected for
waterfowl, shore birds and other water-oriented wildlife not included above,
including the necessary aquatic organisms in their food chain;
R317-2-13:
3D: 2 points.
h. Protected for
agricultural, industrial, and "special" uses;
R317-2-13:
4, 5, and 6: 1 point.
2.
Discharge Standard Factor. Priority points are allotted as follows:
a. Project discharge standards are water
quality based: 5 points.
b. Project
must meet secondary effluent treatment standards: 2 points.
c. Project does not discharge to surface
waters: 0 points.
3.
Restoration from Water Quality Standard Violation.
a. Project WILL RESTORE Designated Water Use:
5 points.
b. Project WILL NOT
RESTORE Designated Water Use: 0 points.
c. Points under this subcategory are assigned
on the basis of whether appropriate water quality standard(s) can be restored
if the respective project is constructed and any other water quality management
controls are maintained at present levels. For a project to receive points
under this subcategory, data from a State-approved waste load analysis must
generally show that the designated water use is substantially impaired by the
wastewater discharge and that the proposed project will likely restore the
numerical water quality standards and designated use(s) identified in
R317-2-12
and
R317-2-14 for
the waterbody.
d. Points may not be
assigned under this subcategory if nonpoint source pollution levels negate
water quality improvement from the proposed construction, if numerical
standards or actual levels of pollutants being discharged are questionable, if
serious consideration is being given to the redesignation of the stream segment
to a lower classification, or if numerical standards for specific pollutants
are inappropriately low for the classified water use.
4. Estimated Improvement in Stream Quality or
Estimated Improvement in Environmental Quality including Presently Unsewered
Communities and Sewered Communities with Raw Sewage Discharges. Points in this
category shall be allocated based upon the judgment of the Division of Water
Quality Staff and on the nature of the receiving water and surrounding
watershed. Consideration shall be given to projects which discharge into Utah
priority stream segments as identified in the biennial water quality report
(305(b)). The criteria used to develop the Stream Segment Priority List may be
used to evaluate projects on other streams not on the Stream Segment Priority
List. These criteria include the existing use impairment, the overall index
from a use impairment analysis, the potential for use impairment, the
downstream use affected, the population affected, the amount of local interest
and involvement toward improving the stream quality, the presence of endangered
species, and the beneficial use classification. Activities within the watershed
that are aimed at reducing point and nonpoint sources of pollution may also be
considered in the allocation of points. In addition, the effect of a discharge
or proposed change in a discharge on the chemical and biological quality of the
receiving stream may be considered in the determination of points. Only those
projects which will significantly improve water quality or environmental
quality and will restore or protect the designated uses or eliminate public
health hazards shall be given the maximum points allowable. Fewer points can be
given in instances where some significant improvement will be achieved if a
project is constructed.
a. The project is
essential immediately, and must be constructed to protect public health or
attain a high, measurable improvement in water quality: 20 points.
b. The project will likely result in a
substantial level of improvement in water quality or public health protection:
10 points.
c. Some level of water
quality improvement or public health protection would likely be provided by the
construction of the project, but the effect has not yet been well established.
Also, present facilities lack unit processes needed to meet required discharge
standards: 5 points.
d. No
significant improvement of water quality or public health protection would
likely be achieved, at present, by a project: 0 points.
D. EXISTING POPULATION
AFFECTED
For sewered communities, priority points are based on the
population served by a treatment facility. For unsewered areas, points are
based on the population of the affected community.
1. Greater than 80,000: 10 points.
2. 40,000 - 80,000: 9 points.
3. 20,000 - 40,000: 8 points.
4. 10,000 - 20,000: 7 points.
5. 5,000 - 10,000: 6 points.
6. 4,000 - 5,000: 5 points.
7. 3,000 - 4,000: 4 points.
8. 2,000 - 3,000: 3 points.
9. 1,000 - 2,000: 2 points.
10. Less than 1,000: 1 point.
E. SPECIAL CONSIDERATION
1. The proposed project is an interceptor
sewer which is part of a larger regional plan and is necessary to maintain the
financial, environmental or engineering integrity of that regionalization plan:
20 points, or
2. The project is

anti- degradation segments: 20 points.
3. The proposed project will change the
facility's sludge disposal practice from a non-beneficial use to a beneficial
use method: 20 points.
