Environmental Protection Act (Ill. Rev. Stat. 1983, ch. 111 1/2, par.

1004).

SOURCE: Adopted at 8 Ill. Reg. 9069, effective July 1, 1984.

SUBPART A: INTRODUCTION

This Part sets forth the procedures and requirements established by the

Illinois Environmental Protection Agency (IEPA) for determining priorities

in awarding grant assistance for the construction of municipal wastewater

treatment works under the Anti-Pollution Bond Act (Ill. Rev. Stat. 1983,

ch. 127, pars. 451 et seq.) and Title II of the Federal Clean Water Act (33

U.S.C. 1281 et seq.).

a) Unless specified otherwise, all terms shall have the meanings set

forth in the Environmental Protection Act (Ill. Rev. Stat. 1983,

ch. 111 1/2, pars. 1001 et seq.) the Federal Clean Water Act (33

U.S.C. 1281 et seq.) and regulations adopted under those Acts (35

Ill. Adm. Code 101 et seq.; 40 CFR 1 et seq.). Federal

regulations referenced in this Part will be applicable as of the

effective date of this Part.

b) For purposes of these rules, the following definitions apply:

"Bond Act" means the State Anti-Pollution Bond Act (Ill. Rev.

Stat. 1983, ch. 127, pars. 451 et seq.).

"PE BOD" is a term used to evaluate the impact of industrial

or other waste on a treatment works or streams in terms of

five day biochemical oxygen demand. One PE BOD equals 0.17

pounds (77g).

"Priority system" means a methodology used to rank projects

for inclusion on the project priority list.

"Project priority list" means an ordered listing of projects

which IEPA expects will receive financial assistance under

the Bond Act or Title II.

"Segment" is a portion of a river basin the surface waters of

which have common hydrologic characteristics or flow

regulation patterns, common natural physical chemical and

biological processes, and which have common reactions to

external stresses, such as the discharge of pollutants.

"Title II" means Title II of the federal Clean Water Act (33

U.S.C. 1281 et seq.).

a) Financial assistance may be awarded under the Bond Act or Title II

only to projects which are identified on the project priority list

developed by IEPA.

b) This Part sets forth a priority system to be used to rank projects

for inclusions on the project priority list. In general, under

this priority system the rank of a project is determined by the

Grant Priority Index (GPI) as calculated under Subpart D, and the

date of submission of the pre-application and project scoring

summary.

c) The project priority list, or amendments thereto, shall be

published annually in the preliminary Water Pollution Control

Program Plan developed in accordance with Section 106 of the

federal Clean Water Act (33 U.S.C. 1256). IEPA shall evaluate and

consider any public comments received concerning the project

priority list. The project priority list shall be published in

the final Water Pollution Control Program Plan.

a) IEPA shall establish from the allotment of funds available under

Title II those reserves under Title II.

b) No grant or combination of grants will be certified in an amount

which will allow a single applicant or a service area of a single

applicant to receive more than 50 percent of the available Federal

and State grant funds, unless such an award or combination of

awards is deemed by the Director of the IEPA to be necessary to

assure that the State of Illinois does not lose portions of its

allotment under Title II.

a) A municipality may submit a pre-application and a priority scoring

summary at any time. The pre-application must identify the scope

of the project, and include a cost estimate and schedule for

completion of the project. The priority scoring summary must

include data to allow calculation of the Grant Priority Index in

accordance with the requirements of this Part.

b) A municipality is not required to renew a pre-application or a

priority scoring summary unless the scope, schedule, scoring data

or grant request differs from that of the previous year, and

unless the municipality has not yet advised IEPA of the changes.

a) IEPA may delete any project from the project priority list if the

applicant fails to make efforts to initiate and complete as

expeditiously as possible all necessary actions appropriate to the

specific grant step for which the discharger is then eligible.

b) Any applicant removed from the project prioirty list is not

eligible to receive grant assistance under Title II or the Bond

Act, unless reinstated on the list in accordance with subsection

(c).

c) An applicant requesting to be reinstated shall submit a new

pre-application and priority scoring summary. The Manager of the

Division of Water Pollution Control may reinstate projects deleted

from the list at the previously held rank or at a lower rank, if

the priority scoring summary so indicates, only after evaluating

all facts and circumstances bearing upon the reasonableness of the

request including, but not limited to, the environmental effects

and cost-effectiveness of achieving water quality goals.

d) An applicant who is not reinstated under subsection (c) may

request the Director to review the decision, but must do so by

submitting a written request setting forth the grounds for

reinstatement within 30 days after receiving notice of the

decision of the Manager of the Division of Water Pollution

Control. The Director will make the final decision determining

the merits of the request in accordance with the requirements of

this Section.

SUBPART B: PROCEDURE FOR CALCULATING THE

MUNICIPAL DISCHARGE INDEX

a) The Municipal Discharge Index (MDI) is a number which is the

product of four factors. The MDI is, in turn, a factor used to

calculate the Grant Priority Index.

b) The MDI is calculated as follows:

MDI - F1 x F2 x F6.

Where the applicant justifies hydraulic and organic loadings on the basis

of influent sampling and flow measurement results for a current 12 month

period, these values will be used. In cases where influent sampling and/or

flow measurement results are not available for a current 12 month period,

and where the applicant justifies estimated connected domestic population

equivalent and provides (measured) industrial population equivalent and/or

where the applicant provides estimated flow based on 100 gpcpd and provides

(measured) industrial flow, these values will be used.

F1 is a factor which evaluates the quantity of wastewater adjusted for

strength. It is calculated as follows:

F1 = log (PE BOD, existing wastewater load)

F2 is a factor which evaluates the adequacy of existing facilities for

treating the existing wastewater load to design levels. It is calculated

as follows:

F2 = <PPE BOD, (existing wastewater load, industrial and domestic)>>

PE BOD, existing design capacity

x <Pdaily average flow, existing load >> +1

daily average flow, existing design capacity

F3 is a factor which evaluates the stream segment receiving the discharge.

The evaluation is done through use of a Segment Ranking Index (SRI). The

SRI is calculated in accordance with Subpart C. F3 is calculated as

follows:

F3 = <PSRI, receiving segment >>

SRI, highest statewide value

a) F6 is a factor used to evaluate the environmental impact of a

discharge. The F6 factor is evaluated at the time of the

submittal of the pre-application and priority scoring summary and

is re-evaluated upon Agency approval of the facilities plan. At

the time of submittal of the pre-application an F6 of 1.0 is

assigned. After facilities planning has been approved F6 will be

evaluated in accordance with subsection (b).

1) If the applicant has an existing sewage collection system and

a central sewage treatment plant an F6 of 1.0 is assigned.

2) For flood control projects or storm sewers an F6 value of 0.1

will be assigned.

3) In cases where a sewage treatment plant is proposed to

provide treatment for a currently unsewered community, an

interceptor sewer(s) is proposed to provide service to an

unsewered area or community, a complete new collection system

is proposed for a currently unsewered community or extension

of an existing collection system is proposed, an F6 will be

assigned based on the summation of the following, except that

F6 will not be greater than 1.0. If information is not

available to score items (C), (D), and (E), they will be set

equal to zero.

A) If after completion and approval of the facilities plan,

no points are assigned based on (B), (C), (D), (E) and

(F) below, F6 shall be 0.

B) One or more discharges which are not complying with an

effluent standard of 30 mg/1 BOD and 30 mg/1 suspended

solids shall result in the addition of 0.1 point.

C) If the aquatic environment in the receiving stream is

polluted, as defined in Section 164.207, downstream of

the applicant's discharge(s) from drainage tiles serving

the community 0.1 point shall be added for each full 600

feet of stream degraded to a polluted environment as a

result of the applicant's activities.

D) If the aquatic environment in the receiving stream is

semi-polluted, as defined in Section 164.207, downstream

of the applicant's discharge(s) from drainage tiles

serving the community 0.075 point shall be added for

each 600 feet of stream degraded as a result of said

discharge(s) to a semi-polluted environment as a result

of the applicant's activities.

E) If the aquatic environment in the receiving stream is

unbalanced, as defined in Section 164.207, downstream of

the applicant's discharge(s) from drainage tiles serving

the community 0.05 point shall be added for each 600

feet of stream degraded as a result of said discharge(s)

to an unbalanced environment as a result of the

applicant's activities.

F) Points from 0.0 to 1.0 shall be given for health hazards

in the municipality resulting from malfunctioning or

inadequate private sewage disposal systems. Assignment

of points shall be based upon:

i) Severity and overall distribution of the health

hazard based on the content of the facilities plan

and field investigations of IEPA in cooperation

with the Illinois Department of Public Health; and

ii) The legal, financial, institutional and managerial

capability of the applicant to implement the

facility plan.

c) Points will be assigned under subsection (b) by the Manager of the

Division of Water Pollution Control. Applicants will be notified

in writing of the points assigned. An applicant who objects to

the points assigned under subsection (b), may request the Director

to review the decision, but must do so by submitting a written

request setting forth the grounds for objection within 30 days of

the date the applicant received notice of the decision of the

Manager of Water Pollution Control. The Director of the Agency

will make the final decision determining the merits of the request

in accordance with the requirements of this Section.

Aquatic environments are classified according to the following:

a) Balanced environment: Intolerant organisms are many in number and

species, or more in numbers than other forms present.

Intolerant Moderate, facultative and

present tolerant usually present

greater than 50% lesser than 50%

b) Unbalanced environment: Intolerant organisms are less in number

than other forms combined, but combined with moderate forms, they

usually outnumber tolerant forms.

Intolerant Moderate, facultative and

present tolerant usually

lesser than 50% present but

but greater than 10% greater than 50%

c) Semi-polluted environment: Intolerant organisms are few or may

not be present. Moderate and/or facultative organisms present.

Intolerant Moderate, faculative and

present tolerant usually

greater than 10% present greater than 90%

d) Polluted environment:

1) Intolerant organisms absent, only tolerant organisms present

or no organisms present.

Tolerant present = 100%

2) Organisms which are not adapted to inhabit a polluted

environment are occasionally collected as a result of factors

produced by the drift and are not representative.

SUBPART C: PROCEDURE FOR CALCULATING THE

SEGMENT RANKING INDEX

a) The Segment Ranking Index (SRI) is an objective determination of

the priority of segments through the use of four factors which are

expressed as numerical factors and combined to establish a ranking

index for each of the basin segments.

b) The SRI is calculated as follows

SRI = Water Quality Index (WQI) x High Quality Water Factor x

Population Factor x National Priorities Factor

a) The WQI factor is determined by comparing the measured value of

certain critical water quality parameters in the waters of the

State with Illinois Pollution Control Board water quality

standards for those parameters.

b) The procedure for calculating the WQI factor is as follows:

1) Average the 1974 and 1975 sample data for each water quality

station for each of the following parameters: dissolved

oxygen, fecal coliform bacteria, ammonia nitrogen, total

dissolved solids, and nitrate plus nitrite nitrogen.

2) Determine the percentage of 1974 and 1975 samples which

indicated violations of applicable water quality standards

for dissolved oxygen, ammonia nitrogen, fecal coliform

bacteria, total dissolved solids, and pH as then set forth in

Chapter 3 of the Board's regulations.

3) The parameter pH (relative acidity) is not considered in

(b)(1) because its nature is such that an "average" pH is

generally meaningless as an expression of water quality.

Nitrate plus nitrite nitrogen is not considered in (b)(2)

because there is no numerical standard which applies for most

water quality sampling stations.

4) The 10 sets of parameter values for each station of all

stream segments are then arranged in order of severity and

given a rank number. These numbers are subsequently combined

to complete a water quality index for each station, according

to the following formula:

S = 1/2 (RA + RV) AMM + 1/2 (RA + RV) Fec Col + 1/2 (RA + RV)

+ 1/2 (RA + RV)TDS + RVpH + RAN+N

where:

S = "Water Quality Index" value for a given station

RA = rank number by average value for a given station

and parameter

RV = rank number by percent violations of water quality

standards for a given station and parameter

Amm, DO, Fec Col, TDS, pH, N + N = parameter designation

subscripts

5) The S values found for each station are used as a basis for

determining a water quality index value for the basin

segments. This process requires the averaging of SSta values

for each segment according to the following formula:

WQI = (S + S + S + . . . + S N)/N

Where WQI = segment water quality index value =

average of station S values for the

segment, and

N = Number of stations in the segment

@R+R

a) Under this factor, populations are computed for each segment and

converted into an adjustment factor. The population of a segment

is defined by the 1980 U.S. census population of the segment

except where inter-segment transfers of sewage occur, in which

case the estimated population whose sewage is tributary to the

segment is added to the resident population of the segment.

Population figures of the incorporated and unincorporated

communities are recorded for each segment. Where a segment

boundary splits a township, the unincorporated population within

the segment is prorated by applying a percentage of the township

population equal to the ratio of the segment area in the township

to the total township area. The populations of the various

political subdivisions within each segment are totaled.

b) The following population factors are applied as multipliers to the

water quality index values:

Segment Population Population Factor

0 - 20,000 1.00

20,001 - 50,000 1.05

50,001 - 100,000 1.10

OVER 100,000 1.20

@R+R

a) Certain segments, such as segments containing a major lake or

impoundment, have been identified as having high-quality waters

where special management and waste control procedures may be

needed for their preservation.

b) It is recognized that certain free-flowing stream reaches also

have high water quality; however, these are not identified as

needing special preservation techniques due to the stringency of

the state's effluent standards. Lakes and impoundments do require

special attention because the effluent standards may not be

sufficient to prevent degradation of water quality in standing

bodies of water. The segments selected under this criterion are

assigned a "high quality water factor" of 1.20. Segments

immediately tributary to these segments are given a factor of

1.10. All other segments are given a factor of 1.00.

@R+R

Segments in the Lake Michigan basin, the Chicago metropolitan area and the

East St. Louis metropolitan area have been designated by the United States

Environmental Protection Agency as having high national priority. They are

therefore assigned a "national priorities factor" of 1.05. All other

segments are given a factor of 1.00.

@R+P

SUBPART D: PROCEDURE FOR CALCULATING

THE GRANT PRIORITY INDEX

@P+R

a) The Grant Priority Index (GPI) is a number which is the product of

three factors. The GPI is used to determine rank on the project

priority list in accordance with Section 364.103.

b) The GPI is calculated as follows:

GPI = MDI x F4 + F5

@R+R

a) The F4 factor considers the corrective measures necessary to

provide the degree of treatment required by applicable effluent

limitations. F4 is derived through a summation of values assigned

for additional treatment process required for currently overloaded

facilities and for rehabilitation.

b) The F4 factor establishes relative values for the following

treatment processes:

1) addition of any required secondary or supplemental treatment

processes where, at the present time, the required processes

are non-existent.

2) addition of capacity for currently (hydraulically and/or

organically) overloaded treatment processes.

3) modification of existing processes which do not increase

capacity or degree of treatment but are necessary for the

upgrading of an existing treatment plant.

4) the construction of new trunk and lateral sewers to provide

an extension of service from an existing collection system or

the rehabilitation of existing sewers, which will not

eliminate excessive infiltration/inflow.

5) the construction of a new collection system and treatment

works to service a presently unsewered community where a

discharge of raw or partially treated sewage exists, or where

no discharge exists.

c) The F4 values are the following:

TABLE OF F4 VALUES

Average Maximum Maximum

Dry Dry Wet

Treatment Weather Weather Weather

Process Flow Flow Flow

Primary 0 0 8

Secondary 14 10 0

Tertiary (10/12) 8 6 0

Disinfection 6 6 6

Phosphorus Removal 5 3 0

Nitrification 8 6 0

Inadequate Sludge Processing Facilities 6

Modification of existing processes which

do not increase capacity or degree of

treatment 1

Wastewater reuse or recycling; Flood

Control Projects; Trunk and Laterial

Sewers 1

Range of Values: 0 to 99

@R+R

a) F5 is a factor which is added for those projects whose priority

position is to be retained.

b) The value of F5 will be retained only if the value of the

quanitity F1 x F2 x F3 x F6 x F4 is greater than the corresponding

quantity for the lowest priority need which has an F5 value

greater than zero. If the value of this quantity does not meet

this test, F5 for the need will be reduced to zero following the

completion of facility planning and subsequent determination of

F6.

@R+R

a) The priority system established in this Part is applied with the

following conventions and general results.

b) For expansion and/or upgrading of an existing sewage treatment

plant, a new sewage treatment plant to serve a currently sewered

area, or sewer rehabilitation work which will eliminate excessive

infiltration/inflow, the MDI value for the plant, together with

the F4 value for the treatment processes affected at the plant are

used to calculate the GPI value for the need. For sewer

rehabilitation projects "treatment processes affected at the

plant" are as follows:

1) Where the sewer rehabilitation work will solve an inflow

problem, the F4 value shall be determined from the existing

need for provision of complying primary treatment and/or

disinfection for wet weather flow in excess of maximum dry

weather flow, unless additional treatment is required to meet

effluent standards.

2) Where the sewer rehabilitation work will solve an

infiltration problem, the F4 value shall be determined from

the existing need for provision of complying primary and/or

secondary and/or tertiary and/or advanced and/or supplemental

treatment of dry weather flow.

3) Where the sewer rehabilitation work will solve an

infiltration and inflow problem, the F4 value shall be

determined from the existing need for provision of complying

primary and/or secondary and/or tertiary and/or advanced

and/or supplemental treatment of dry weather flow as well as

the existing need for provision of primary and/or

disinfection of wet weather flow in excess of maximum dry

weather flow, unless additional treatment of the excess flow

is required to meet effluent standards.

4) Under (b)(1)-(3), existing need is determined using

overload/no overload criteria for existing treatment

processes and dilution ratio for additional processes

required by effluent standards.

c) For construction of a new sewage treatment plant or improvements

to existing individual sewage disposal units or a combination of

the two for a currently unsewered community, since a quantifiable

discharge does not exist, an "equivalent" MDI value must be

calculated. For this purpose, the estimated current population

equivalent of the area to be served is used in calculating F1; F2

is set equal to 1.0; and the segment to receive the proposed

discharge determines F3. A significance factor to reflect the

impact of the dicharge on the receiving stream and public health

hazards is determined as described in Section 364.206 to calculate

F6. The MDI is then calculated. The treatment processes required

at the proposed sewage treatment plant determine F4. The GPI is

then calculated.

d) For construction of a new regional plant or expansion and/or

upgrading of an existing sewage treatment plant to phase out one

or more existing sewage treatment plants, the highest of the MDI

values as sell as the highest of the F4 values among the values

for the existing or proposed regional plant and the values for the

existing plant(s) to be phased out (exclusive of non-municipally

owned treatment works) are used to calculate the GPI for the

regional plant.

e) For construction of a new sewage treatment plant or improvements

to individual existing sewage disposal units or a combination of

the two for a currently unsewered community where a discharge of

raw or partially treated sewage does exist. A "discharge of raw

or partially treated sewage" exists, for purposes of determining

priority, if the applicant establishes that the PE (BOD) of the

discharge from the sewer system is at least equal to 65 percent of

the total domestic population plus 100 percent of any tributary

industrial PE BOD, on the basis of no less than three samples (24

hour composite) of the discharge, collected directly from the

"sewer system" outfall to the receiving stream and from comparable

flow measurements of the discharge, on different days. Copies of

laboratory reports must be submitted as a part of the facilities

planning documents to permit a need to qualify under these

criteria, and an on-site investigation by Agency representatives

may be made, in which case the results of the Agency investigation

will be considered conclusive for scoring purposes. Since an MDI

value does not exist, an "equivalent" MDI must be calculated. For

this purpose, estimated current population equivalent of the area

to be served is used in calculating F1; F2 is set equal to 2.0;

and the segment to receive the proposed discharge determines F3.

A significance factor to reflect the impact of the discharge on

the receiving stream and public health hazards is determined as

described in Section 365.206 to calculate F6. The MDI is then

calculated. The treatment processes required at the proposed

treatment plant determine F4. The GPI is then calculated.

f) For relief intercepting sewers, where the existing intercepting

sewer is not capable of transporting the flows which are presently

tributary to it, proceed in accordance with Section 364.404(b)

where the relief intercepting sewer is a sanitary sewer and in

accordance with Section 364.404(j) where the relief sewer is a

combined sewer.

g) For transport of sewage from end point(s) of existing collection

system(s) to an existing or proposed regional sewage treatment

plant proceed in accordance with Section 364.404(d).

h) For transport of sewage from end point(s) of proposed collection

system(s) to an existing or proposed regional treatment plant or

improvements to individual existing sewage disposal units or both,

the calculation of the F1, F2 and F6 values proceeds similarly to

that in Section 364.404(c) above. The F4 value will be selected

from the larger of the values for the degree(s) of treatment which

would be required at the local location of the collection system

and at the regional plant. The F3 value will also be selected

from the larger of the values for the basin segment containing the

collection system and the basin segment containing the regional

plant.

i) For construction of an intercepting sewer or improvements to

existing individual sewage disposal units or both for a currently

unsewered community where a discharge of raw or partially treated

sewage does exist, an MDI value does not exist, and an

"equivalent" MDI must be calculated. For this purpose, estimated

current population equivalent of the area to be served is used in

calculating F1; F2 is set equal to 1.0; and the segment to receive

the proposed discharge determines F3. The MDI is then calculated.

The treatment processes required at the proposed sewage treatment

plant determine F4. The immediate impace of the discharge on the

receiving stream and public health hazard are used as described in

Section 364.206 to calculate F6. The GPI is then calculated.

j) For elimination or treatment of on-system wet weather overflow(s)

from combined sewers, regardless of the approach to solving this

problem or the extensiveness of the problem, the MDI for the plant

currently providing service, and an F4 value of 14 (established

values for primary treatment and disinfection of maximum wet

weather flow) are used in the calculation of a GPI value.

k) For construction of trunk and lateral sewers where rehabilitation

work not eliminate excessive infiltration/inflow, the MDI value

for the plant, together with F4 and F6 values of 1, are used to

determined the GPI value; therefore, GPI = MDI.

l) For construction of a complete new collection system, the GPI

value will be equal to that of the proposed plant under Section

364.404(c) or intercepting sewer under Section 364.404(g).

m) For extension of service by an existing collection system, the

calculation of the MDI value proceeds similarly to that in Section

364.404(d) except that in this case estimate of the existing

population equivalent to be served by the sanitary sewer extension

only is used in determining F1. The F4 values for this case are

equal to 1, the F6 is calculated in accordance with Section

364.206. The GPI is then calculated.

n) For construction of an intercepting sewer parallel to an existing

intercepting sewer, which existing sewer is capable of

transporting the flows which are presently tributary to it; flood

control projects; and wastewater recycling or wastewater reuse

projects, the MDI value for the plant, together with an F4 value

of 1 are used to determine the GPI value, therefore, GPI = MDI.

@R+R

a) Effects of Overloading

1) For an overloaded facility, values from the table of F4

values for the average and maximum design flow for existing

treatment processes will be assigned to the need.

2) For a facility which is not overloaded as defined above, but

where sludge handling capacity is presently inadequate, 6

points for sludge handling facilities will be assigned to the

need. Sludge handling will be determined to be inadequate

where the connected population equivalent (for a 12 month

period) exceeds the Agency approved and permitted design

basis of the sludge handling units.

3) If the facility is not overloaded based on the average daily

flow, the need may receive credit for overloading on the

maximum dry weather flow. Where the applicant justifies, on

the basis of influent flow measurement for a 12 month period

that the average of the peak dry weather flows to the plant

exceeds the design peak capacity of the plant for complete

treatment of dry weather flow, the need will receive credit

for overloading under maximum dry weather flow conditions.

b) Ongoing Construction

1) At the time of scoring of a need for priority, in situations

where other construction has been completed for expansion of

capacity and/or increased degree of treatment, the priority

score will not include the need for the processes which have

been constructed.

2) Needs which consist of plant improvements and/or intercepting

sewers, and which will be satisfied through construction in

several phases (projects), will be addressed by scoring all

phases (projects) with the full credit for the entire need.

c) Flow Diversion

Needs which will result in the diversion of a portion of the

average dry weather flow from one plant to another plant will be

scored utilizing the regionalization convention for the two

plants.

d) Integrally Related Projects

1) Two or more needs of one or more applicants, which are

initially ranked at different priorities, may be consolidated

into one need at the higher (highest) priority, if the

following conditions are satisfied:

A) The facilities plan, must conclude that the two or more

needs are integrally related through the cost-effective

solution; and

B) State and Federal funds must be available to permit

complete funding of the consolidated need.

2) Such consolidations may include:

A) sewer rehabilitation work and sewage treatment plant

improvements and/or intercepting sewer construction;

B) projects to eliminate on-system wet weather overflow and

sewage treatment plant improvements and/or intercepting

sewer construction;

C) projects to construct collection systems and new sewage

treatment plant and/or intercepting sewer construction.

3) This provision does allow the award of grants (for projects

which are integrally related to a priority project), to

municipalities which had not filed an application for grant

at the time of preparation of the priority list for the

fiscal year.

e) Complete Waste Treatment Systems

After Agency approval of a facilities plan, and at the time of the

subsequent revision to the priority list, the Agency shall add any
