FINAL SCHEDULE OF SEWER RENTS AND OTHER CHARGES FOR
				2021-2022
TO PROVIDE FUNDS FOR THE FIXED CHARGES AND FOR THE OPERATION
				AND MAINTENANCE OF THE ENTIRE SEWER SYSTEM IN THE CITY OF BUFFALO AND ALL OF
				THE BUFFALO SEWER AUTHORITY FACILITIES FOR THE CONVEYANCE, TREATMENT AND
				DISPOSAL OF SEWAGE AND STORM WATER OPERATED BY THE BUFFALO SEWER
				AUTHORITY.
I.
SEWER RENTS FOR PREMISES SITUATED WITHIN THE LIMITS
				OF THE CITY OF BUFFALO
(a) $12,050,000 shall be collected from all real property in
				the City of Buffalo (the "City") by apportioning the said amount upon such
				property within the City as the same is set down on the last completed annual
				assessment roll of the City, except that no
ad valorem
sewer
				rent shall be assessed against real property exempt from real property taxes
				pursuant to subdivision one of section four hundred, sections four hundred
				four, four hundred six, four hundred twelve, four hundred eighteen, subdivision

III.
GENERAL PROVISIONS
(a) In the event a person, lot, parcel of land, building or
				premises discharging sewage, water or other liquids into the Authority sewer
				system, either directly or indirectly, is a user of water supplied by the
				Buffalo Water Board, and the quantity of water used is not measured by a water
				meter acceptable to the Authority, then the sewer charge or rental for all such
				accounts shall be in the respective amounts (expressed in dollars) set forth in
				Exhibit A, attached hereto and made a part hereof, as the Authority determines
				applicable to such person, lot, parcel of land, building or premises.
(b) In addition to all other rentals and charges provided
				herein, a monthly drainage connection service charge shall be due for any and
				all persons, lots, parcels of land, building or premises, other than a City
				department, that discharge sewage, water or other liquids into the Authority
				sewer system, either directly or indirectly, as follows:
1. A monthly charge of $6.00 shall be due for all lots,
				parcels, land, buildings or premises where the quantity of water used is not
				measured by a meter acceptable to the Authority.
2. A monthly charge in the amounts set forth below shall be due
				for all lots, parcels, land, building or premises where the quantity of water
				used is measured by a meter acceptable to the Authority in accordance with the
				following meter size:

(c) In the event a person, lot, parcel of land, building or
				premises discharging sewage, water or other liquids into the Authority sewer
				system, which directly or indirectly, uses water obtained from a source other
				than the Buffalo Water Board, and the water so obtained is not measured by a
				water meter acceptable to the Authority, then, in each such case, the owner,
				user or other interested party shall, at his own expense, furnish, install, and
				maintain a water meter or other water or sewage measuring device acceptable to
				the Authority and the quantity of water used, as measured by said meter, or as
				otherwise determined, shall be used to determine the sewer charge or rental and
				there shall be charged an amount determined as set forth in paragraphs II(a),
				III(a) and III(b) as the case may be.
(d) In the event a person, lot, parcel of land, building or
				premises discharging sewage, water or other liquids into the Authority sewer
				system, either directly or indirectly, uses water in excess of 4,000 cubic feet
				per quarter year and it can be shown to the satisfaction of the Authority, that
				a portion of the water as measured by the water meter does not and cannot enter
				the Authority sewer system, then the Authority may determine in such manner as
				may be found practicable the percentage of metered water entering the Authority
				sewer system and the quantity of water used to determine the sewer charge or
				rental shall be that percentage, so determined, of the quantity of water
				measured by the water meter, or the Authority may require or permit the
				installation of additional meters or measuring devices in such a manner as to
				determine the quantity of water or sewage actually entering the Authority sewer
				system, in which case the quantity of water used to determine the sewer charge
				or rental shall be the quantity of water actually entering the Authority sewer
				system and so determined.
(e) In the event a person, lot, parcel of land, building or
				premises discharges sewage or other wastes into the Authority sewer system
				which, in the opinion of the Authority, contain unduly high concentrations or
				any substances which add to the operating costs of the Authority facilities,
				then the Authority may elect to establish and collect special rates of charge,
				based on the quantity of these substances, which rate of charge may be
				established and collected in such manner as the Authority may elect and such
				charge shall be paid to the Authority, or it may elect to exclude such sewage
				or other wastes from its facilities.
(f) As a condition of a Buffalo Discharge Elimination System
				Permit (BPDES), a user may be required to pay an industrial waste surcharge for
				discharging sewage or waste exhibiting a strength of sewage or waste greater
				than normal domestic sewage. The Industrial Waste Surcharge Formula reflecting
				the Treatment Plant unit costs for treatment of Biochemical Oxygen Demand
				(BOD5) Total Suspended Solids (TSS) and Total Phosphate
				(TPO4) is as follows:
Surcharge = 8.34 QMGY (0.1855 (BOD5-250)
				+ 0.2079 (TSS-250) + 0.0203 (TPO4-15.35))
$0.1855 Cost/lb. for treatment of BOD5
				$0.2079 Cost/lb. for treatment of TSS $0.0203 Cost/lb. for treatment of
				TPO4
QMGY shall mean the annual total industrial and sanitary
				discharge - water retention.
BOD5 shall mean the average
				concentration of BOD5 in sewage or waste discharged to
				the Authority facilities.
TSS shall mean the average concentration of TSS in sewage or
				waste discharged to the Authority facilities.
TPO4 shall mean the average
				concentration of TPO4 in sewage or waste discharged to
				the Authority facilities.
Surchargeable concentrations are as follows:
BOD5 - Over 250 mg/L; TSS - Over 250
				mg/L; TPO4 - Over 15.35 mg/L
This formula shall be applied in computing the Buffalo
				Industrial Waste Surcharge subsequent to July 1, 2020 and ending June 30, 2021
				for all users that discharge sewage or waste exhibiting a strength of sewage or
				waste greater than normal domestic sewage. In addition, this formula with the
				above rates will be used to calculate all monthly, quarterly, semiannual, and
				annual accounts subsequent to July 1, 2021.
(g) Any person who violates the Sewer Regulations of the
				Authority or the conditions of the permits issued thereunder shall be subject
				to fines as specified in said regulations.
(h) Whenever sewage or other wastes result in conditions in the
				Authority sewer system as to cause blockage or a substantial reduction in the
				flow, charges for the work necessary to eliminate such blockage or reduction in
				flow may be made, based upon costs incurred by the Authority for labor,
				materials, equipment hire, insurances, and other overhead, against the owner of
				the property or premises that caused the discharge of such sewage or other
				wastes into the Authority sewer system.
(i) Where sewer facilities have been installed to serve
				improved and unimproved property and have been paid for in whole or in part by
				the Authority, a charge shall be made based on a proportionate share of the
				original cost, determined by the foot frontage of the parcel served, or by the
				area of such parcels, or by such other method the Authority determines to be
				equitable, as a condition to a permit for a connection to the Authority's
				facilities.
(j) An application and inspection fee for sewer connection
				permits shall be paid as follows at the time said application is filed with the
				Authority:

(k) An application fee of $50 per 2,500 square feet or part
				thereof of soil disturbance or impervious area being drained, whichever is
				greater, shall be paid at time of plans and/or calculations are submitted to
				the Authority for site stormwater management review.
(l) An application fee of $150 plus $25 for every 100 linear
				feet or part thereof of new sanitary sewer pipe proposed shall be paid at the
				time that plans and/or calculations are submitted to the authority for any
				facility proposing to discharge 2,500 gallons per day or more of additional
				sanitary and/or industrial flow than existing conditions.
(m) All persons owning or operating a pump truck or other
				transport vehicle and desiring to discharge wastes, directly or indirectly,
				into the Authority's facilities shall first secure a valid Truckers Discharge
				Permit after paying an annual permit fee of $120.00. In addition to said permit
				fee, a separate charge shall be billed based upon the verified quantity or
				truck capacity, and character of the waste discharged and, if applicable, the
				point of discharge.
The following surcharge rates are hereby charged for such
				wastehaulers who are located outside the City:
DISCHARGE LOCATION
TOTAL SUSPENDED
							 SOLIDS

$0.0998/lb.
$0.0271/lb.
Thickener/Digester
$0.1749/lb.
$0.1065/lb.
$0.0271/lb.
The above surcharge rates, along with costs incurred by the
				Authority when handling, testing, conveying, and administering each
				wastehauler, will be used to determine the cost per gallon of each wastestream.
				The wastehauler user charges for various wastestreams are as follows:
1.
Septage and portable toilet wastes
- The
				rate of $0.04 per gallon discharged will be assigned to all permitted septage
				and portable toilet wastehaulers.
2.
Grease trap wastes
- The rate of $0.05 per
				gallon discharged will be assigned to all permitted grease trap
				wastehaulers.
3.
Sludge wastes
- This rate will vary
				dependent on strength and volume. Sludge rates will be calculated using the
				parameter costs for the mixing tank location.
4.
Miscellaneous Wastes
-This rate will vary
				dependent on strength of waste, volume and discharge location.
These rates will be used for all permits effective July 1,
				2021.
(n) In the event a person, lot, parcel of land, building or
				premises threatens to discharge or discharges sewage or waste into or near the
				Authority's publicly owned treatment works, either directly or indirectly,
				which in the opinion of the Authority will or is likely to bypass, upset, harm
				or endanger the facilities of the Authority, then such person or the owner or
				operator of such lot, parcel of land, building or premises shall pay to the
				Authority charges for any and all clean up, removal and remediation costs
				actually incurred by the Authority, including but not limited to labor,
				materials, equipment, insurances or laboratory services for the (i) containment
				or attempted containment of such discharge or threatened discharge, (ii)
				sampling and analysis of such discharge or threatened discharge, (iii) removal
				or attempted removal of such discharge or threatened discharge, (iv) taking of
				reasonable measures to prevent or mitigate damage to property, public health,
				safety or welfare, or (v) remediation, treatment, storage or disposal of such
				discharge or threatened discharge and all soils, water or structures affected
				by such discharge.
(o) All industrial users and wastehaulers shall pay to the
				Authority a charge for the actual costs of analysis incurred by the Authority
				for monitoring of any and all discharges of such users.
(p) Any person who is granted a temporary permit to discharge
				into the facilities of the Authority shall pay a permit fee of $800.00 to the
				Authority as a condition of the issuance of such permit.
(q) Except as otherwise defined herein, all terms and phrases
				used or contained in this schedule of sewer rents shall bear the same meaning
				and definition as set forth in the Authority's Sewer Use Regulations 21
				N.Y.C.R.R. Part 10075 and New York Public Authorities Law Section 1175
et seq.
(r) Sewer rents and charges as herein provided shall be payable
				at the office of the Director of the Treasury for the City at Room 117, City
				Hall, Buffalo, New York 14202, or at such other location or address as may be
				set forth on the Authority's invoice, and shall become due and payable as
				follows:
1. So much of the sewer rents and charges as are based upon
				water use and the drainage connection service charge covering the respective
				premises, or such other charges as provided herein shall be due and payable,
				except as otherwise stated in this schedule or in such invoice, on the same
				day, one month following the month of the invoice billing date, and such
				invoice may be billed monthly, quarterly or as otherwise determined by the
				Authority; and
2. So much of the sewer rents and charges as are based upon the
				assessed valuation of chargeable real estate shall become due and payable from
				the first day of July 1938, and each year thereafter, and may be paid without
				interest on or before September 30th next succeeding.
(s) Such sewer rents and charges that remain unpaid after their
				respective due dates shall be charged interest, and such interest shall
				continue to be charged until such sewer rents and charges are paid in full, as
				follows:
1. sewer rents based upon water use and drainage connection
				service charges shall be charged interest at the same rate as unpaid City
				taxes, to wit: four and one-half percent (4.5%) interest shall be added to
				amounts unpaid from the first through the thirtieth day after the due date and
				thereafter one and one-half percent (1.5%) shall be added to all amounts that
				remain unpaid for each succeeding month;
2. sewer rents based upon assessed valuation of chargeable real
				estate that remain unpaid on October 1st of each year shall be charged interest
				at the rate of two percent (2%), and such sewer rents that remain unpaid shall
				be charged two percent (2%) for each month thereafter until paid; and
3. all other sewer rents and charges of the Authority shall be
				charged interest at the rate of one and one-half percent (1.5%) per month if
				not paid by the due date stated on the invoice issued by the Authority.
(t) All persons and property served by the Authority shall be
				subject to paying reasonable costs and expenses, including attorney fees
				incurred in the collection of sewer rents and charges that remain unpaid, as
				may be determined by the Board of the Authority. In addition to any other
				remedy or provision hereof, the Authority reserves the right to engage in such
				collection activities, as it deems appropriate, for all accounts that remain
				unpaid after the due date. In consideration of such collection activities and
				to defray the cost thereof with respect to accounts based on water use and
				drainage connection service, the person or property served by the Authority may
				pay an additional charge of twenty-one percent (21%) of the amount of each such
				delinquent account, together with interest as provided herein, that remains
				unpaid for more than (i) one hundred twenty (120) days from the due date for
				metered accounts, and (ii) two hundred ten (210) days from the due date for

APPENDIX 2
BUFFALO SEWER AUTHORITY
SAMPLING MEASUREMENT AND ANALYTICAL GUIDELINES SHEET
(
Revised 1/28/00
)
A. Flow Monitoring and Sampling
(1) Before commencement of any sampling or flow monitoring, the
				Industrial Waste Section (I.W.S.) shall be notified, in writing, at least
				seventy-two (72) hours in advance by the firm or designee. The I.W.S. will give
				a twenty-four (24) hour verbal notification to the firm or designee if split
				sampling will be required.
(2) Sampling must be performed at the designated B.P.D.E.S.
				permit location.
(3) All discharge lines from one (1) building, or all discharge
				lines from only one (1) single process, must be sampled during the same time
				period.
(4) If a sample point receives flow from upstream roof drains
				and/or storm connections, sampling will not be acceptable during a
				precipitation day. If sampling was initiated before a storm and the storm is
				brief or near the end of sampling the I.W.S. must be contacted for approval to
				accept the sample collected for analysis.
(5) If an auto-sampler is used, tubing must be at least \ 3
				I.D. and the intake hose velocity must be at least 2.0 f.p.s. with a minimum
				lift of twenty (20) feet.
(6) After the first day of sampling, the tubing must be cleaned
				with detergent or methanol and deionized water for each subsequent sampling
				day. Proper refrigeration and preservation of the sample must be maintained
				during the entire sampling period.
(7) All sampling shall be taken at the highest velocity,
				greatest turbulence and center of flow.
(8) All sampling must be done on normal work days. If there is
				a regulated process discharge after normal working hours, sampling must
				continue until there is no further discharge.
(9) The discharge flow monitoring method must be approved by
				the B.S.A. prior to monitoring. Results and the method used to determine flow
				must be included with the report.
(10) Any split samples with the B.S.A. that indicate an
				analytical discrepancy of greater than 20% may be grounds for disapproval of
				the monitoring report.
B. Analytical
(1) The pH must be analyzed from the sample on site unless
				otherwise specified.
(2) When the following parameters are required to be monitored
				for the Baseline Monitoring Report (BMR) and Compliance Monitoring Report (CMR)
				a minimum of four (4) grab samples must be collected for each parameter: pH,
				cyanides, total phenols, oil and grease, sulfide, and volatile organics. Grab
				samples must be taken over an equally spaced time period during a normal work
				day. The sample bottle(s) must be glass when oil & grease, total
				extractable hydrocarbons and/or organics are being tested. The method of
				sampling for all periodic permit monitoring requirements will be specified in
				the B.P.D.E.S. permit.
(3) Only laboratories certified by the New York State
				Department of Health for the specific parameter will be allowed to conduct the

APPENDIX 3
BSA's MASS ALLOCATION APPROACH TO PRETREATMENT PROGRAM
				IMPLEMENTATION
1.0
INTRODUCTION
The Buffalo Sewer Authority (BSA) recently completed its
				development of a pretreatment program in conformance with the General
				Pretreatment Regulations ( 40CFR 403). A formal application for the approval of
				this program has been prepared and submitted to both the United States
				Environmental Protection Agency (USEPA) and the New York State Department of
				Environmental Conservation (NYSDEC). Once this program has been approved, the
				BSA will have the primary responsibility of ensuring that all industrial users
				of the Authority's wastewater collection and treatment system comply with both
				the BSA pretreatment program requirements and the EPA categorical pretreatment
				standards.
The primary mechanism to be utilized by the BSA to ensure
				industrial compliance with its sewer use regulations will be industrial
				discharge limits which have been developed for various pollutants. This
				approach is mandated by the General Pretreatment Regulations (40CFR
				403.5(c)), which require
				that POTW's developing pretreatment programs derive and enforce specific local
				discharge limits which will be applied to all industrial users within the
				POTW's service area. The actual function of these local limits is to protect
				both the BSA POTW against interference from pollutants and the environment from
				pollutants which pass through the treatment facility. The BSA has opted to
				refine the limit development process by deriving critical (allowable) mass
				loadings for each control parameter addressed. This approach gives the
				industries more operational leeway regarding discharges and allows the BSA more
				flexibility in administering the pretreatment program while still protecting
				the BSA treatment plant.
The purpose of this report is to present the derivation and
				allocation of critical mass loadings for the control parameters identified in
				the BSA's Industrial Pretreatment Program report. Both the methodology used to
				develop this approach and the ramifications of its implementation are
				discussed.
2.0
METHODOLOGY
The methodology utilized to allocate the critical influent
				masses for specific control parameters identified in the BSA's Industrial
				Pretreatment Program is presented in detail in Appendix A. The process of
				deriving these critical masses is comprised of several basic steps. First is
				the determination of critical influent limits for the control parameters.
				Threshold pollutant concentrations which would either inhibit wastewater and
				sludge treatment processes, adversely impact sludge disposal practices or cause
				NYS water quality standards to be exceeded were calculated, taking into
				consideration the BSA POTW's ability to remove the identified pollutants. The
				critical limit for each pollutant was then determined to be the most
				restrictive of the threshold concentrations derived previously.
The second step is the development of specific industrial
				discharge limits based on the allocation of allowable pollutant mass loadings.
				The treatment plant critical influent mass was calculated using the POTW design
				hydraulic capacity (180 mgd) and the critical influent concentration for each
				pollutant. This quantity was then distributed between four loading categories:
				uncontrollable sources (domestic, natural background, etc.), present industrial
				users, an unallocated portion reserved for future industrial users and a
				non-allocated safety margin. The portion of the POTW's critical mass which has
				been allocated to the existing industrial users will be distributed according
				to each industry's discharge volume and pollutant loading. The mass limits
				designated for each industry will be implemented through the BSA's BPDES permit
				system, with all pollutant mass discharge restrictions being set forth in the
				respective discharge permits.
3.0
CRITICAL INFLUENT MASS ALLOCATION
3.1
Critical Influent Mass
The critical influent mass is the maximum amount of a pollutant
				that could be received at the POTW without any adverse effects being
				experienced. Generally, this mass is expressed as a loading rate, such as
				pounds per day. The critical influent mass for any pollutant is determined by
				multiplying the POTW's design hydraulic capacity (180 mgd) times the
				pollutant's critical influent concentration (limit) and the appropriate
				conversion factors to get the loading rate. The calculations made to obtain the
				critical masses listed in Table 1 are presented in Appendix B.
The critical influent mass is also the quantity which is
				apportioned among the four loading categories. These categories represent both
				the masses of pollutants which are being received at the treatment plant
				currently and additional amounts reserved for POTW protection and future
				industrial users. A description of each loading category follows.
3.2
Safety Factor
A safety factor equal to twenty percent of the critical
				influent mass has been set aside for each control parameter (except selenium)
				as a non-allocated reserve. This reserved amount provides a margin of safety to
				ensure both protection of the POTW and compliance with SPDES permit
				requirements.
3.3
Uncontrollable Source Mass
For each pollutant received at the POTW, a specific load is
				attributed to background sources such as eroded minerals and
				domestic/commercial discharges. These quantities of the pollutants cannot be
				controlled by the BSA through enforcement of sewer use regulations.
				Consequently, the uncontrollable mass of each pollutant has been subtracted
				from the total mass available for allocation to industrial users. The specific
				mass of pollutants from uncontrollable sources is calculated by multiplying the
				design hydraulic capacity of the POTW times the background concentration for
				each pollutant and the appropriate conversion factors. Background
				concentrations were obtained by sampling sewer flows in areas which were not
				downstream of any industrial sources. The analytical results were considered to
				be representative of natural background concentrations for all control
				parameters. In comparison, the results of a similar analytical program are
				shown in Table 2. As can be seen, the concentrations found in the BSA's system
				are quite similar to those obtained elsewhere.
One problem this approach has presented is that for PCB, BHC,
				pyrene and 1,2,4-dichlorobenzene, the background concentrations recorded were
				higher than the POTW's critical influent limits. This may indicate that the
				samples taken are not truly representative and that additional sampling should
				be completed, which seems to be the case since the critical influent limits for
				these parameters are not being exceeded in the treatment plant influent.
3.4
Allocated Mass
To determine the portion of the critical influent mass for each
				control parameter to be allocated to industrial users, data from the BSA's
				Pretreatment Program industrial survey were used. Various industrial users were
				sampled for parameters related to their specific manufacturing processes. From
				the available data, the loadings of each control parameter discharged to the
				POTW were calculated using an industry's discharge rate and detected pollutant
				concentrations. For each parameter, all industrial loads were complied to
				produce each respective allocated mass (Table 1). In cases where a categorical
				industry was discharging a pollutant at concentrations exceeding the
				appropriate categorical pretreatment standard discharge limits, the categorical
				limits were used for calculation purposes since this discharge level will be
				required once the BSA Pretreatment Program is approved by the USEPA.
				Calculations used to develop the allocated mass loading for each control
				parameter are presented in Appendix C.

NOTES TO TABLE 1
(1) Control parameters were derived as described in Section 7
				of the Draft Final Report for the Buffalo Sewer Authority Industrial
				Pretreatment Program (submitted June 1983, URS Co., Inc.). The parameters PCB,
				BHC, Pyrene and 1, 2,4-dichlorobenzene were not included in this table due to
				background concentrations which were higher than their respective critical
				influent limits.
(2) The critical influent masses for the control parameters
				were developed based on the critical influent concentration limits presented in
				Table 7-5 of the URS report cited in Note 1.
(3) The masses predicted for the uncontrollable sources are
				based on the background concentrations listed in Table 7-8 of the URS report
				cited in Note 1.
(4) Allocated masses for the control parameters were developed
				from the sampling and analysis program results of the BSA Industrial
				Pretreatment Program. Discharges from firms now out of business were not
				included in the calculations. Industrial discharge concentrations exceeding
				Pretreatment Program limits have been calculated using the respective
				limits.
To prevent an industry from discharging its total allowable
				daily loading over a short time period, (i.e., slug or batch discharges),
				maximum instantaneous discharge concentrations for each pollutant have been
				developed and included in both the BSA's Sewer Use regulations and all
				discharge permits.
3.5
Unallocated Mass
Following the calculation of the pollutant loadings which
				comprised the safety margin, uncontrollable source and allocated mass loading
				categories for each control parameter, a quantity of the respective critical
				influent masses remained unallocated. These unallocated masses remain reserved
				for any industries which may begin to discharge to the BSA system in the future
				or for the expansion of existing industries.
4.0
THE MASS ALLOCATION APPROACH
Under this mass allocation system, existing industrial sources
				will be allocated an allowable mass discharge limit equivalent to their present
				discharge level. Following Categorical Pretreatment Standard compliance dates,
				industries subject to the standards will be allocated a mass based on the
				regulated concentration limits and their respective discharge volumes. Should
				an existing industry expand its production level, its allowable mass discharge
				will be increased accordingly by giving it a portion of the unallocated mass
				reserve. .Similarly, if a new industry begins to operate within the BSA's
				service area, its allowable discharge mass would be taken from the unallocated
				mass reserve. Conversely, if an industry reduces or ceases production, its
				allocated mass which is lost would be placed into the unallocated
				reserve.
Table 1 is a summary table for the mass allocation of
				pollutants received by the BSA POTW. Each control parameter's critical influent
				mass is divided between the four loading categories. To help clarify the
				relationships between these categories for each parameter, pie charts are
				presented in Figures 1 through 16. As indicated, all of the control parameters
				except selenium exhibit considerable unallocated masses which are available for
				future industrial expansion. It is reasonable to expect from this information
				and in consideration of the industrial environment within the BSA's service
				area, that this approach to implementing the pretreatment program should
				operate adequately in the future. The selenium problem is one which must be
				addressed, but this will serve as a good test of the reallocation system which
				may be required again in the future.
The intent of the BSA in implementing the mass allocation
				approach is to provide a degree of flexibility to the administration of its
				pretreatment program. Benefits which may be realized initially by industry as a
				result of using mass allocation include the elimination of industry's need to
				install costly pretreatment facilities required to remove pollutants adequately
				handled by the POTW. In the future, if the POTW's critical influent mass for
				any of the control parameters should be reached or if the unallocated mass
				should be depleted, the BSA will have to reallocate the masses for the problem
				pollutant such that some industries may find it necessary to pretreat their
				wastewater to remain in compliance.
The mass of each specific pollutant that initially will be
				allocated to specific industrial users once this mass allocation system is
				implemented is presented in Appendix C. Presently, it is anticipated that all
				BPDES permits containing the specific mass limits will be issued during the
				first five (5) months following EPA/NYSDEC approval of the Authority's
				pretreatment program. (Assuming that program approval will be received during
				August 1984, all BPDES permits will be issued by January 1985.) Top priority
				will be given to issuance of BPDES permits to Electroplating and Metal
				Finishing facilities. Subsequently all other permits will be issued. The total
				number of BPDES permits to be issued is 222.

APPENDIX A
INDUSTRIAL WASTE DISCHARGE
MASS ALLOCATION MANUAL
DEVELOPMENT OF LOCAL INDUSTRIAL DISCHARGE LIMITS
Introduction
The primary function of the local pretreatment program is to
				provide a mechanism for the control of industrial pollutants which can have a
				significant adverse impact on the POTW or the receiving stream water quality.
				The development and enforcement of local industrial discharge limits are
				essential mechanisms for meeting these objectives. The development process
				basically involves identification of those operational, environmental and
				health and safety factors which are most sensitive to and could be most
				adversely impacted by industrial pollutants. Limits are then derived which are
				expressly designed to mitigate and prevent the potential for an adverse
				impact.
The methodology used to develop the limits which have been
				incorporated into the BSA Sewer Use Regulations are presented in this manual.
				All revisions of existing limits and development of additional limits will also
				be based on this methodology.
Methodology
The approach to develop specific industrial discharge limits
				effort is based on initial determination of critical treatment plant influent
				concentrations necessary to meet the following objectives:
(1) Prevent inhibition or upset of the treatment plant
				anaerobic digestion process.
(2) Prevent inhibition or upset of the treatment plant aerobic
				process.
(3) Prevent limitation of sludge disposal options.
(4) Prevent contravention of N.Y. State water quality
				standards.
(5) Prevent violation of incinerator air emission
				standards.
Critical influent limits developed on the basis of the basis of
				the criteria identified are used to derive critical mass loadings for each
				pollutant of concern. This mass is then allocated - in conjunction with the BSA
				BPDES permit system - to industrial contributors in the form of mass discharge
				limits.
The specific manner in which critical influent limits and
				industrial mass limits are developed is presented below.
Critical Influent Limits. Critical influent limits are
				developed for the BSA
treatment plant using the methodology of Anthony
				and Breimhurst, 1981 (Ref.1). This methodology involves the following
				steps:
(1) Identify the pollutants (especially the priority
				pollutants) which are present in the BSA sewerage system and could have an
				adverse impact.
(2) Determine the threshold pollutant concentrations that: 1)
				are inhibitory to the BSA wastewater and sludge treatment processes, 2) would
				adversely impact on sludge disposal or 3) would contravene NYS water quality
				standards.
(3) Determine the efficiency of pollutant removal in the BSA
				treatment plant and the portion of the total pollutant load that is retained in
				the sludge.
(4) Derive limiting treatment plant influent concentrations
				necessary to achieve each of the objectives stated above using mathematical
				relationships which incorporate the information determined in steps 1-3
				above.
(5) By comparison of the limiting concentrations derived,
				determine the most critical concentration for each pollutant.
The specific manner in which this methodology is applied to
				derive limits to meet the previously stated objectives is presented
				below.
Inhibition of the Anaerobic Sludge Digestion Process - The
				pollutant concentrations which are limiting to the BSA anaerobic sludge
				digestion process are calculated on the basis of the methodology presented in
				Table 1. Values for Cs and Rp
				will be determined from the literature.

Inhibition of the Aerobic Process (Activated Sludge) - The
				pollutant concentrations which are inhibitory to the BSA activated sludge
				process will be calculated as shown in Table 2. Values for
				Cp and R p will be determined
				from the literature.

				Limits Necessary to Prevent Inhibition of the BSA Activated Sludge
				Process.

Cp
=
limiting concentration in primary treatment system
						  effluent based on inhibition of activated sludge (mg/l)
Rp
=
percent of pollutant removal in treatment plant primary
						  system
Limitation of Sludge Disposal Options - The BSA presently
				incinerates its wastewater treatment plant sludge and landfills the ash.
				Occasionally, when the incinerators aren't operating the sludge is landfilled.
				This situation is not expected to change in the foreseeable future. Therefore,
				the consideration of other sludge disposal options, such as landspreading, is
				impractical for purpose of defining limiting pollutant influent concentrations.
				Furthermore, no problems have been noted in the past which would adversely
				impact on continuation of the present practice of sludge disposal. For example,
				both the BSA sludge and incinerator ash have been tested for a hazardous.
				leachate potential (i.e. EP Toxicity test) and were determined to be
				nonhazardous. For these reasons, the development of limiting influent
				concentrations necessary to prevent limitation of sludge disposal options is
				not presently required.
Contravention of N.Y. State Water Quality Based Permit Limits -
				The BSA's most recent SPDES draft permit contains proposed water quality based
				discharge limitations for a number of pollutant parameters. The maximum
				treatment plant influent concentrations which could be allowed without
				violating such limits are calculated as shown in Table 3. Values for C
				e are taken directly from the BSA's SPDES permit. Values
				for R o will be determined on the basis of historical
				BSA treatment plant data.

						  plant
Violation of Incinerator Emission Standards - Since the BSA
				incinerates its sludge it is subject to the National Emission Standards for
				Hazardous Air Pollutants ( 40 CFR Part 61 ). Review of these standards
				indicates that mercury is presently the only pollutant parameter which is
				pertinent to BSA's situation. The methodology for determination of the maximum
				treatment plant influent concentration which could be allowed without violating
				the mercury emission standard is presented in Table 4.

The value for I s is determined from the

				is determined from the literature (Ref. 2). Values for Q
				ip and Q are determined on the basis of BSA Treatment
				Plant data and information. The value for R o is
				determined on the basis of historical BSA treatment plant data.
Summary of Critical Limits - The critical limit for each
				pollutant is defined as the most restrictive of the limiting concentrations
				derived on the basis of the criteria and methodology identified above.
Industrial Limits - The approach used to develop specific
				industrial discharge limits is based on derivation and allocation of critical
				pollutant (allowable) mass loadings. The treatment plant critical influent mass
				is determined on the basis of the critical influent concentration and the
				treatment plant hydraulic design capacity (e.g. 180 MGD) according to the
				following relationship:
Critical Inf. Limit (mg/l) * g/1000 mg * 1b/454 g * 3.785
				l/gal. * hydraulic design capacity (180 MGD) =Critical Inf. Mass
To determine the quantity of the critical mass available for
				allocation to industrial users, the mass contributed by uncontrollable sources
				(domestic sources, etc.) is subtracted. Twenty percent of the critical influent
				mass is also subtracted and permanently set aside as a nonallocated reserve to
				provide a margin of safety for treatment plant protection and compliance with
				SPDES permit water quality based limits.
Under this mass allocation system, existing industrial sources
				will be allocated an allowable mass discharge limit equivalent to their present
				level of discharge. (Following Categorical Pretreatment Standard Compliance
				Dates, industries subject to such standards will be allocated a mass based on
				the regulated concentration limits and each industry's volume of discharge.)
				All unallocated mass will be set aside in an unallocated mass reserve. This
				situation allows the BSA to exercise flexibility in administration of this
				system. For example, when an existing industry expands its production level,
				its allowable mass discharge could be increased accordingly by giving that
				industry a portion of the unallocated mass reserve. Likewise, when a new
				industry moves into the BSA service area, its allowable mass discharge would
				also be drawn from the unallocated mass reserve. Conversely, when an existing
				industry moves out of the BSA service area, its mass allocation would be placed
				back into the unallocated mass reserve.
The mass allocation system described above is specifically
				designed to protect the treatment plant and receiving stream water quality
				without imposing unnecessary regulatory restrictions on industry. This system
				is especially intended to eliminate the need for industry to install costly
				pretreatment facilities to remove pollutants that are being adequately removed
				at the BSA treatment plant and that are not present in the treatment plant
				influent at levels that could have an adverse impact on the treatment plant
				operation. If, however, the treatment plant critical influent limit for any
				pollutant is approached or the mass reserve depleted, the BSA will reallocate
				the mass for that pollutant such that some industries may find it necessary to
				pretreat their wastewater to remove that pollutant.
The mass limits allocated to each industry will be implemented
				through the BSA BPDES permit system. All pollutant mass discharge restrictions
				will be set forth in each industry's permit. To prevent an industry from
				discharging its total allowable daily mass over a short period of time (i.e.
				slug or batch discharges), maximum instantaneous discharge concentration limits
				for each pollutant parameter will also be placed in each permit and the Sewer
				Use Regulations. The slug discharge limits have been determined on the basis of
				the following relationship:
S
=
2.5R (Lp - B)
Where:
S
=
maximum allowable instantaneous discharge concentration
						  (mg/l).
R
=
ratio of the treatment plant influent volume to the
						  volume of industrial discharges containing a given pollutant
Lp
=
critical treatment plant influent concentration for any
						  given pollutant (mg/l).
B
=
background concentration (mg/l) (e.g. pollutant
						  contribution by domestic and commercial sources).
Values for R are obtained from the results of the industrial
				survey. Specifically, the industrial sources of each of the pollutants have
				been determined on the basis of the wastewater discharge analyses submitted by
				all the significant industrial users in the BSA service area, including the
				outlying service areas. Then, for each individual pollutant, the total volume
				of wastewater from all industrial sources of that pollutant was determined.
				Each value for R was then determined by dividing the total volume of wastewater
				received at the BSA treatment plant by the total volume of industrial
				wastewater containing a given pollutant.
To determine the background concentrations (B) of pollutants
				(i.e. pollutant quantities from uncontrollable sources such as private
				residential areas, commercial establishments and storm water runoff), samples
				of sewerage were collected for subsequent analysis from locations in the BSA
				sewer system that contained no industrial wastes.
