DEVELOPERS AND PROVIDES A BENEFIT TO A DEFINED 
AREA. 
ii. 
ONE OR MORE ADDITIONAL DEVELOPERS WILL LIKELY 
DIRECTLY OR INDIRECTLY CONNECT TO THE PROJECT. 
iii. 
THE INFRASTRUCTURE COSTS EXCEED $1,000,000.00, OR 
THE AREA BENEFITTED BY THE PROJECT, EXCEPT FOR THE 
FIRST DEVELOPER’S PROPERTY, IS COMPRISED SOLELY OF 
STATE TRUST LAND AND THE DIRECTOR HAS AGREED TO 
WAIVE THE $1,000,000.00 MINIMUM REQUIREMENT.  
 
(3) 
FOR THE PURPOSES OF THIS ARTICLE, AN INDIRECT CONNECTION 
MEANS THAT A DEVELOPMENT IS HYDRAULICALLY BENEFITED BY, 
BUT IS NOT DIRECTLY CONNECTED TO, A CLASS 2 PROJECT.  
 
(4) 
FOR THE PURPOSES OF THIS ARTICLE, OFF-SITE 
INFRASTRUCTURE MEANS INFRASTRUCTURE NECESSARY OR 
BENEFICIAL TO A DEVELOPMENT THAT IS NOT LOCATED ON THE 
PROPERTY OF THE DEVELOPMENT. 
 
(b)     THE DIRECTOR MAY REQUIRE A DEVELOPER TO INCREASE THE 
CAPACITY OF OFF-SITE INFRASTRUCTURE. IF INCREASED CAPACITY IS 
REQUIRED, THE CITY WILL BE RESPONSIBLE FOR THE COST OF THE 
INCREASED CAPACITY. THE CITY’S CONTRIBUTION TO THE PROJECT 
WILL BE SUBTRACTED FROM THE TOTAL COSTS USED TO CALCULATE 
THE REPAYMENT AMOUNT THAT IS OWED TO THE DEVELOPER UNDER A 
REPAYMENT AGREEMENT.

37 
 
(c)     THE DEVELOPER MUST EMPLOY A CIVIL ENGINEER REGISTERED IN THE 
STATE OF ARIZONA TO PERFORM FIELD ENGINEERING, SUBMIT 
DETAILED PLANS AND SPECIFICATIONS, AND SUBMIT INFORMATION ON 
EXISTING OR PROPOSED INFRASTRUCTURE, DEVELOPMENT PLANS, 
LOCAL DRAINAGE CONDITIONS AND OTHER ITEMS THAT ARE

REPAYMENT PROGRAM ARE COSTS OF ENGINEERING AND DESIGN 
PLANS, DIRECT LABOR COSTS, SUBCONTRACT COSTS, COSTS OF 
MATERIALS AND EQUIPMENT INCORPORATED IN THE COMPLETED 
CONSTRUCTION, AND STAKING AND MATERIALS TESTING. THE 
DEVELOPER MUST INCLUDE ALL COST ITEMS EXCEPT THOSE RELATED 
TO ENGINEERING AND DESIGN PLANS, MATERIALS TESTING, AND 
STAKING IN THE BIDS THAT ARE SUBMITTED TO, AND REVIEWED BY, THE 
DEPARTMENT. THE DEVELOPER MUST SHOW ALL UNIT PRICING ON ALL 
BIDS. THE DEVELOPER MUST PROVIDE, AND SUBMIT TO THE 
DEPARTMENT FOR REVIEW, ALL COST ITEMS RELATED TO 
ENGINEERING AND DESIGN PLANS, MATERIALS TESTING, AND STAKING 
ON THE ENGINEER’S LETTERHEAD.  THE CITY AND DEVELOPER WILL 
AGREE UPON THE ENGINEERING COSTS FOR DETERMINATION OF 
TOTAL CONSTRUCTION COST PRIOR TO EXECUTION OF THE 
REPAYMENT AGREEMENT; HOWEVER, THE ENGINEERING COSTS MAY 
NOT EXCEED 20 PERCENT OF THE CONSTRUCTION LOW BID.  ELIGIBLE 
PROJECT COSTS DO NOT INCLUDE COSTS ASSOCIATED WITH 
TEMPORARY FACILITIES, PERMIT FEES, TAXES OR ATTORNEY’S FEES. 
THE DEPARTMENT MAY ALLOW ADDITIONAL DIRECT CONSTRUCTION 
COSTS TO BE INCLUDED IN THE TOTAL PROJECT COST; HOWEVER, THE 
ADDITIONAL DIRECT COSTS MAY NOT EXCEED IN THE AGGREGATE 10 
PERCENT OF THE LOWEST CONSTRUCTION BID SUBMITTED.  INTEREST 
IS NOT ELIGIBLE FOR RECOVERY UNDER THE REPAYMENT PROGRAM. 
(e)     TO QUALIFY FOR A REPAYMENT AGREEMENT, THE DEVELOPER MUST 
SUBMIT A MINIMUM OF THREE WRITTEN SEALED BIDS FOR THE 
PROJECT CONSTRUCTION TO THE DEPARTMENT PRIOR TO

38 
 
ACCEPTANCE OF THE PROJECT BY THE DEPARTMENT. THE CITY MAY 
REVIEW ALL BID SUBMISSIONS, REJECT ANY OR ALL BIDS, AND REQUIRE 
THAT THE PROCESS BE REPEATED USING BIDS SUBMITTED BY 
DIFFERENT CONTRACTORS. THE DEVELOPER MUST ENSURE THAT BIDS 
ADEQUATELY REPRESENT THE FULL EXTENT OF THE ANTICIPATED 
CONTRACT REQUIREMENTS, INCLUDING FACILITY LOCATIONS AND 
SIZES, SITE CONSTRAINTS, MATERIAL AND LABOR QUANTITIES. THE 
COSTS ELIGIBLE FOR REPAYMENT MAY NOT EXCEED THE LOWEST OF 
THE THREE BIDS EXCEPT THAT THE DIRECTOR MAY APPROVE 
REIMBURSEMENT OF ADDITIONAL COSTS THAT WOULD HAVE BEEN 
ELIGIBLE IF INCLUDED IN THE LOW BID BUT WERE UNFORESEEABLE 
WHEN THE CONTRACT WAS BID; HOWEVER, UNFORESEEN COSTS MAY 
NOT EXCEED IN THE AGGREGATE 10 PERCENT OF THE LOW BID.  
(f)     UPON COMPLETION OF THE CLASS 1 OR CLASS 2 PROJECT AND FINAL 
ACCEPTANCE OF THE PROJECT BY THE DEPARTMENT, THE PROJECT 
BECOMES PROPERTY OF THE CITY, IS SUBJECT TO EXCLUSIVE 
CONTROL BY THE CITY, AND IS SUBJECT TO ALL PROVISIONS OF THIS 
CHAPTER. THE DEVELOPER MUST ENSURE THAT THE PROJECT IS FREE 
AND CLEAR OF ALL ENCUMBRANCES AND LIENS.  
(g)     IF THE DIRECTOR DETERMINES THAT THE CLASS 1 OR CLASS 2 
PROJECT QUALIFIES FOR THE REPAYMENT PROGRAM, THE CITY MAY 
ENTER INTO A REPAYMENT AGREEMENT WITH THE DEVELOPER. IN 
ADDITION TO OTHER APPROPRIATE TERMS AND CONDITIONS, THE 
REPAYMENT AGREEMENT WILL INCLUDE ALL OF THE FOLLOWING:  
(1)     A JUST, EQUITABLE AND REASONABLE CHARGE TO BE PAID BY 
PERSONS WITHIN THE BENEFITING AREA MAKING A CONNECTION 
TO THE CLASS 1 OR CLASS 2 PROJECT. THE CONNECTION 
CHARGE WILL BE DETERMINED BY DIVIDING THE PROJECT COST 
BY THE MAXIMUM SERVICE AREA ACREAGE. THE MAXIMUM 
SERVICE AREA ACREAGE IS THE DEVELOPER’S SERVICE AREA 
PLUS THE BENEFITING AREA. PROJECT COSTS ASSOCIATED WITH 
THAT PORTION OF THE MAXIMUM SERVICE AREA THAT FALLS 
WITHIN THE DEVELOPER’S SERVICE AREA WILL BE EXCLUDED 
FROM THE TOTAL REPAYMENT AMOUNT AND ARE SOLELY THE 
RESPONSIBILITY OF THE DEVELOPER. 
(2)     REPAYMENT AGREEMENT CHARGES WILL NOT AFFECT THE RIGHT 
OF THE CITY TO ASSESS ANY BUILDING PERMIT, CONNECTION 
FEE, OR OTHER CHARGES, FEES AND TAXES AGAINST THE 
OWNERS OF PROPERTY LOCATED WITHIN THE MAXIMUM SERVICE 
AREA OF THE PROJECT.

39 
 
(3)     THE REPAYMENT AGREEMENT FOR CLASS 1 PROJECTS WILL 
TERMINATE 10 YEARS FROM THE DATE OF EXECUTION BY THE 
DEVELOPER, OR WHEN THE TOTAL REPAYMENT AMOUNT IS 
REPAID, WHICHEVER OCCURS FIRST.  
(4)     THE REPAYMENT AGREEMENT FOR CLASS 2 PROJECTS WILL 
TERMINATE 20 YEARS FROM THE DATE OF EXECUTION BY THE 
DEVELOPER, OR WHEN THE TOTAL REPAYMENT AMOUNT IS 
REPAID, WHICHEVER OCCURS FIRST.  
(5)     IN ORDER FOR THE DEPARTMENT TO RECOVER COSTS 
ASSOCIATED WITH THE ADMINISTRATION OF A REPAYMENT 
AGREEMENT, THE DEPARTMENT WILL CHARGE $500.00 OR $2.00 
PER ACRE TIMES THE BENEFITING AREA, WHICHEVER AMOUNT IS 
GREATER. THE DEVELOPER MUST PAY THE CHARGE AT THE TIME 
OF EXECUTION OF THE REPAYMENT AGREEMENT. IN ADDITION, 
THE DEPARTMENT WILL RETAIN 3 PERCENT OF THE MONIES 
COLLECTED UNDER A REPAYMENT AGREEMENT. 
(6)     ANY PERSON CONNECTING WITHIN THE BENEFITING AREA 
CONNECTING TO A CLASS 1 OR CLASS 2 PROJECT MUST PAY THE 
CONNECTION CHARGE. THE DEPARTMENT WILL REMIT THE 
APPROPRIATE AMOUNT TO THE PERSON ENTITLED TO RECEIVE 
THE PAYMENT UNDER THE REPAYMENT AGREEMENT WITHIN 90 
DAYS OF RECEIPT BUT WILL RETAIN THE 3 PERCENT 
ADMINISTRATION FEE REFERENCED IN PARAGRAPH 5 OF THIS 
SUBSECTION.  
(7)    IF A PROJECT IS LOCATED IN AN AREA IN WHICH SEWER IMPACT 
FEES ARE ASSESSED AND THE FACILITY IS ELIGIBLE FOR CREDIT 
AGAINST FEES, THE DEVELOPER WILL ONLY RECEIVE CREDIT 
AGAINST IMPACT FEES FOR THAT PROPORTION OF THE PROJECT 
COST THAT THE REPAYMENT AGREEMENT ALLOCATES TO THE 
DEVELOPER. THE DEVELOPER MAY NOT BE REPAID FOR PROJECT 
COSTS FOR WHICH IMPACT FEE CREDITS WERE ISSUED. 
(8)     IN CERTAIN SITUATIONS, IT MAY BE DESIRABLE FOR THE 
DEVELOPER TO INCREASE ITS PROPORTION OF THE PROJECT 
COST TO INCREASE ITS SHARE OF IMPACT FEE CREDITS. THE 
DEVELOPER MAY REQUEST THAT THE CONNECTION CHARGES IN 
THE BENEFITING AREA BE REDUCED SO THAT THE TOTAL 
PROPORTION OF COST ATTRIBUTABLE TO THE DEVELOPER IS 
INCREASED. AT THE SOLE DISCRETION OF THE DIRECTOR, A 
REDUCTION IN CHARGES MAY BE PERMITTED, AND IF

40 
 
IMPLEMENTED, WILL BE APPLIED UNIFORMLY TO ALL BENEFITING 
AREAS IN THE REPAYMENT AGREEMENT.  
(a)    The repayment program only applies to projects that are Class 1 or Class 2 
projects. A Class 1 project means the installation of a sewer main that is eight inches or 
greater in diameter that will serve multiple properties or developments. A Class 2 project 
means the installation of a sewer main that is 12 inches or greater in diameter or a lift 
station (including associated force mains) (or a combination of such sewer mains and lift 
stations) that is: A constructed by one or more developers and provides a benefit to a 
defined area; B at a later date is directly or indirectly connected to by one or more 
developers; and C the infrastructure costs exceed $1,000,000.00. The City may grant 
an exception to requirement "C" if the benefited area, minus developer’s property, is 
comprised exclusively of State trust land. An indirect connection is defined as one which 
is hydraulically benefited by, but is not directly connected to, the Class 2 project.  
(b)    The City reserves the right to increase the capacity of the off-site infrastructure if it 
deems the increase necessary to serve the surrounding area. Under this condition, the 
City will be responsible for the cost of the increased capacity. The City’s contribution to 
the project will be removed from the total costs used to calculate the repayment amount 
that is owed to the developer of the Class 1 or Class 2 project.  
(c)    The developer is required to employ a civil engineer registered in the State of 
Arizona to perform field engineering, submit detailed plans and specifications, and 
submit information on existing or proposed infrastructure, development plans, local 
drainage conditions, and other items that are deemed necessary by the City to establish 
the benefiting area to be serviced by the Class 1 or Class 2 project. The City, using 
local drainage conditions and other factors it deems appropriate, shall make the final 
determination of the benefiting area to be serviced by the Class 1 or Class 2 project. 
The final detailed plans and specifications for the main sewer extension and any 
associated off-site major wastewater facilities must be approved by the City before 
construction begins. The construction must meet City specifications, requirements, and 
approval and will be subject to inspection by the City during construction.  
(d)    The developer will be responsible for furnishing and installing to City specifications 
all branch and lateral sewers, including manholes, within new subdivisions, shopping 
centers, industrial tracts, or similar developments. The costs of designing, staking, and 
constructing these branch and lateral sewers are not eligible for recovery under the 
repayment program.  
(e)    Direct project costs eligible for recovery under the repayment program are costs of 
engineering and design plans, direct labor costs, subcontract costs, costs of materials 
and equipment incorporated in the completed construction, and staking and materials 
testing. All cost items except those related to engineering and design plans, materials

41 
 
testing, and staking must be included in the bids that are submitted to, and reviewed by, 
the City. Unit pricing must be shown on all bids. Eligible project costs do not include 
costs associated with temporary facilities, permit fees, taxes, or attorney’s fees. At its 
discretion, the City may include additional direct costs in the total project cost, but in no 
event shall the direct costs exceed ten percent of the construction low bid.  
(f)    The developer is responsible for all costs associated with the engineering, design, 
and construction of the Class 1 or Class 2 project. Design and construction of the 
facilities must be in accordance with the City’s design standards, procedures, policies 
and practices, and final detailed plans, and specifications for a Class 1 or Class 2 
project must be approved by the City prior to construction.  
(g)    In order to qualify for a repayment agreement, the developer shall submit a 
minimum of three written sealed bids for the construction of the project to the City prior 
to acceptance of the project by the City. The City reserves the right to review all bid 
submissions, to reject any or all bids, and if necessary, to require that the process be 
repeated using bids submitted from different contractors. It is the responsibility of the 
developer to ensure that bids adequately represent the full extent of the anticipated 
contract requirements, including facility locations and sizes, site constraints, material, 
and labor quantities. Unit pricing must be shown on all bids. The costs eligible for 
repayment may not exceed the lowest of the three bids except that, in its discretion, the 
City may approve reimbursement of additional costs that would have been eligible if 
included in the low bid but were unforeseeable when the contract was bid, provided in 
no event will such unforeseen costs exceed in the aggregate ten percent of the low bid.  
(h)    Upon completion of the Class 1 or Class 2 project by the developer and 
acceptance of the project by the City, the project shall become the property of the City, 
free and clear of any encumbrances and liens.  
(i)    The City shall have exclusive control of connections to the Class 1 or Class 2 
project, and all provisions of the City Code, as may be amended, applicable to sewer 
service and charges inside and outside City boundaries shall apply. If the City 
determines that the Class 1 or Class 2 project qualifies for admission to the repayment 
program, then the City shall enter into a repayment agreement with the developer. The 
repayment agreement will include the following, in addition to those terms and 
conditions deemed appropriate by the City: 
(1)    A just, equitable, and reasonable charge to be paid by persons or entities 
within the benefiting area making a connection to the Class 1 or Class 2 project. 
The connection charge will be determined by dividing the Class 1 or 2 project cost 
by the maximum service area acreage (the developer’s service area plus the 
benefiting area). Project costs associated with that portion of the maximum service

42 
 
area that falls within the developer’s service area are solely the responsibility of the 
developer. 
(2)    The connection charge will be paid to the City from any person or entity within 
the benefiting area connecting to the project. Once collected, the City within 90 
days of receipt will remit the appropriate amount to the developer or the person 
entitled to receive such payment. In no event shall the total repayment amount 
provided to the developer exceed 97 percent of that portion of the construction 
cost of the Class 1 or Class 2 project that is allotted to the benefiting area acreage 
outside of the developer’s service area. 
(3)    Repayment agreement charges will not affect the right of the City to assess 
any building permit, connection fee (sewer tap), sewer service or other charges, 
fees, and taxes against the owners of property located within the maximum service 
area.  
(4)    The repayment agreement for Class 1 projects shall terminate in ten years 
from signing by the developer, or when the total repayment amount is repaid, 
whichever occurs first. 
(5)    The repayment agreement for Class 2 projects shall terminate in 20 years 
from signing by the developer, or when the total repayment amount is repaid, 
whichever occurs first. Provided the developer has complied with subsection (e) of 
this section regarding sealed bids, a repayment agreement for a Class 2 project 
may be executed on or within 180 days of acceptance of the project by the City. 
Further, if subsection (e) of this section has been complied with, permits may be 
issued for a Class 2 project for which a repayment agreement will be sought.  
(6)    In order for the City to recover costs associated with the administration of a 
repayment agreement, a charge of $500.00 or $2.00 per acre times the benefiting 
area, whichever amount is greater, shall be paid by the developer at the time of his 
signing of the repayment agreement. In addition, the City is entitled to keep three 
percent of the monies collected under a repayment agreement, and will deduct this 
amount from all connection charges it receives prior to remitting the balance to the 
developer or the person entitled to receive the payment. 
(7)    If a project is located in an area in which wastewater impact fees are 
assessed and the developer is eligible to apply impact fee credits against costs, 
the developer will only receive credits against costs for that proportion of the 
project cost that the repayment agreement allocates to the developer. In no event 
will the developer be repaid for project costs for which impact fee credits were 
issued.

43 
 
(8)    In certain situations, it may be desirable for the developer to increase its 
proportion of the project cost to increase its share of impact fee credits. The 
developer may request that the connection charges in the benefiting area be 
reduced so that the total proportion of cost attributable to the developer is 
increased. At the sole discretion of the Water Services Department, such a 
reduction in charges may be permitted, and if implemented, shall be applied 
uniformly to all benefiting areas in the repayment agreement.  
Sec. 28-24. RESERVEDSewer extensions in advance of a sewer assessment 
district. 
The sewer extension policy provisions of the City in regard to sewer installations in 
advance of sewer assessment districts and the policy to be followed in connection 
therewith shall be, and the same is hereby, declared to be as follows: 
(a)    At the option of the developer of an individual parcel of land or of subdivision, 
he may apply for payment of the sewer line or lines necessary to connect his 
development to a trunk sewer. He may also apply for payment of the sewer lines 
within his development. 
(b)    In order to qualify for payment, the sewer lines to be installed must be usable 
by a future assessment district, and the developer must sign an agreement 
whereby the assessable area of any parcel or parcels immediately adjacent to and 
served by such lines will be included in the assessment district and will receive an 
assessment for which the developer will be liable, regardless of whether he sells 
part or all of the property to be assessed. 
(c)    The developer shall pay all construction costs, including engineering services. 
The design, location, and construction must be approved by the City, and a permit 
must be secured from the City Engineer. The contractor shall be duly licensed. 
(d)    The sewer lines installed by the developer will be held in trust by the City for 
sale to a special assessment district in the City. The agreed construction cost, not 
exceeding the actual cost for the lines, will be written into the construction bid as a 
lump sum item and will become part of the construction cost for the special 
assessment district. 
(e)    The property owners adjacent to lines installed by the developer can connect 
to these lines by signing an agreement, which will be recorded, to accept an 
assessment in the assessment district. 
(f)    If the developer desires to enter into private agreements with adjacent 
property owners in which they agree to share his cost for the privilege of

44 
 
connecting to the sewer lateral, he may do so, but these property owners will still 
be required to sign an agreement with the Water Services Department in which 
they agree to accept an assessment in the assessment district. 
(g)    There will be only one purchase agreement for each project. No attempt will 
be made to negotiate with more than one party, regardless of how many are 
sharing the cost. 
(h)    Payment will be made at the completion of the assessment district or at the 
time that assessments become payable.

FEET OF A WATER LINE TRENCH. 
Sec. 28-30. Special provisions for installing sewer taps in new subdivisions and 
developments. 
In new subdivisions or developments where public sewer extensions are authorized by 
the City and constructed at the developer’s expense, the City may authorize the 
developer or hisITS agent, if he so desires, to install sewer taps with wyes or tees and 
connect the lateral sewers to the building connection under the following provisions: 
A.(a)    The construction of the public sewer, sewer taps, and connections of the 
lateral sewer to the sewer tap shallMUST be under the supervision of a registered 
civil engineer holding registration in the Sstate, who shallMUST submit "as-built 
plans," bearing the registered civil engineer’s registration seal and number, to the 
Planning and Development Department.  
(b)    It IS THE DEVELOPER’S RESPONSIBILITYshall be the duty of the

ARTICLE V. SEWER SERVICE CHARGES 
Sec. 28-34. Method of developing sewer service charges. 
The user charge portion of the total sewer service charge shall beIS developed 
byUSING the following methodology. 
(a)    The following formulas shall beARE used to develop the various elements of 
the user charge portion of the sewer service charge. 
(1)    A treatment plant charge (T) will be made to all customers on the basis 
of flow and strength of sewage discharged. It shall be AND IS calculated as 
follows: 
Flow Rate 
= Total Flow Costs

49 
 
 
 
Total Gallons of Flow 
Treated 
BOD Rate 
= Total BOD Costs 
Pounds of BOD Treated 
Suspended 
Solids Rate 
 
= 
 
Total TSS Costs 
Total Pounds of TSS 
Treated 
T 
= User’s Gallons X Flow 
Rate + User’s BOD X 
BOD Rate + User’s TSS 
X TSS Rate 
(2)    A sewer maintenance charge (S) will be made to all customers using the 
City’s sewer system and will beIS calculated as follows: 
S = User’s 
Gallons 
X Total Cost of Sewer 
Maintenance 
Total Gallons of Flow 
(b)    The elements of THE charge developed in section 28-35(a) shall beARE 
applied to the various customer classifications as follows: 
(1)    Customers connected to THE City of PhoenixSEWER collection 
system: 
  
User Charge = T + S 
(2)    Other cities using the treatment facilities but not connected to THE 
City’S PUBLIC SEWERof Phoenix collection system: 
  
User Charge = T 
Sec. 28-35. Determination of sewage quantityDISCHARGE VOLUME. 
(a)    Calculation of CUSTOMER sewage flow shall beDISCHARGE VOLUME IS based 
upon the following proportion of metered water consumption each year. 
(1)    Eighty percent of the average monthly water VOLUME billed during the 
precedingA RELEVANT PRIOR January, February, and March multiplied by the 
SFSF described in section 28-35(a)(8) shall representS sewage flowDISCHARGE 
VOLUME for single-family residential customers.

50 
 
a. 
THE “WINTER QUARTER AVERAGE” OR “WQA” IS A 
CALCULATED ESTIMATE OF EACH USER’S MONTHLY WATER 
VOLUME USE DURING THE MONTHS OF JANUARY, FEBRUARY, AND 
MARCH OF A RELEVANT PRIOR FISCAL YEAR. WQA’S ARE 
RECALCULATED ANNUALLY. THE RECALCULATED WQA BECOMES 
EFFECTIVE ON THE FIRST DAY OF THE NEW FISCAL YEAR (JULY 1) 
AND REMAINS IN EFFECT UNTIL THE LAST DAY OF THAT FISCAL 
YEAR (JUNE 30). 
(2)    If the Director determines that adequate water meter information is not 
available for billing a residential customer as described above, then the customer 
will be charged the average monthly SEWER billing for that user class. 
(3)    Eighty-five percent of the average monthly water VOLUME billed during the 
preceding A RELEVANT PRIOR January, February, and March multiplied by the 
SFSF described in section 28-35(a)(8) shall representS sewage flowDISCHARGE 
VOLUME for all multifamily residential customers and all commercial customers 
with the exception of self-service laundries and ice producers. 
(4)    Eighty-five percent of the monthly water meter reading multiplied by the SFSF 
described in section 28-35(a)(8) shall representS sewage flowDISCHARGE 
VOLUME for self-service laundries. 
(5)    Fifty percent of the average monthly water VOLUME billed during the 
precedingA RELEVANT PRIOR January, February, and March multiplied by the 
SFSF described in section 28-35(a)(8) shall representS sewage flowDISCHARGE 
VOLUME for ice producers. 
(6)    If the Director determines that adequate water meter information is not 
available TO CALCULATE SEWAGE DISCHARGE VOLUME for billing a 
commercial customer as described above, then the customer’S ESTIMATED 
SEWAGE DISCHARGE VOLUME will be charged a bill estimatedBASED on the 
basis ofMETERED water used by a similar sized commercial customer in the same 
user class. 
(7)    Each industrial customer will be considered as a separate user class and the 
Director shallWILL determine the individual factors to be applied to the monthly 
water meter reading to determine the monthly sewage flowDISCHARGE VOLUME. 
(8)    Estimated sewage flowDISCHARGE VOLUME for all customers other than 
industrial customers will beIS further adjusted by a sewer flow stabilization factor 
(SFSF). The SFSF is a factor that adjusts the current billed sewer flows (from the 
precedingA RELEVANT PRIOR January, February, and March water consumption

51 
 
or monthly water consumption) to reflect sewer flow used to develop the sewer 
rates. The SFSF is calculated as follows: 
SFSF = Billed water consumption per 
account other than industrial 
customers used for sewer rates 
 
 
Current billed sewer flow per 
account from water 
consumption other than 
industrial customers 
(b)    Other cities will be billed on the basis of their sewer meter reading, with 
changes in rates effective July 1 each year. 
(cb)    All users for which the water supply is from other suppliers of water may furnish 
to theTHE Director MAY RELY ON either a certified meter reading of water delivered, or 
a copy of the billings from the water supplier, FOR USERS THAT RECEIVE WATER 
FROM A SUPPLIER OTHER THAN THE CITY. The Director shall haveHAS the 
exclusive authority to determine the adequacy of this information and request additional 
documentation or tests if The DIRECTOR finds the information supplied IS inadequate 
TO ESTABLISH THE VOLUME OF WATER SUPPLIED TO THE USER’S PROPERTY. 
If the Director finds the information adequate, the user’s SEWER charges will be 
calculated and the same conditions will apply as if the City were the supplier of water to 
the user. 
(dc)    Upon approval of the Director, any individual user may, at his ownTHE USER’S 
expense and subject to the regulations of the Department, install a separate WATER 
meter in order to determine the quantity of water actually entering the sewer system and 
future sewer charges shall be limited to that water actually entering the sewer system as 
so determined by the DirectorON A LINE FROM WHICH WATER DOES NOT ENTER 
THE SEWER SYSTEM. THE CALCULATION OF THAT USER’S SEWAGE 
DISCHARGE VOLUME WILL NOT ACCOUNT FOR THE METERED WATER 
DELIVERED TO THIS WATER LINE. 
(d)    SEWAGE DISCHARGE VOLUME ADJUSTMENT. CUSTOMERS THAT HAVE 
THEIR SEWAGE DISCHARGE VOLUME CALCULATED BASED ON A PROPORTION 
OF METERED WATER SUPPLIED TO THEM IN JANUARY, FEBRUARY, AND 
MARCH MAY REQUEST THAT THE DEPARTMENT DECREASE THE SEWAGE 
DISCHARGE VOLUME USED TO CALCULATE THEIR ANNUAL SEWER CHARGE 
PROVIDED ALL OF THE FOLLOWING: 
 (1) 
THE CUSTOMER EXPERIENCED EVENTS OR CIRCUMSTANCES AT 
ITS PROPERTY IN THE WQA MONTHS—E.G. POOL FILLING, WATER LINE

52 
 
LEAK, EXTRAORDINARY IRRIGATION OR LANDSCAPE WATERING—THAT 
RESULTED IN THE AMOUNT OF ITS ACTUAL DISCHARGE TO THE SEWER 
BEING LESS THAN THE SEWAGE DISCHARGE VOLUME CALCULATED BY 
THE DEPARTMENT AND SET FORTH IN THE CUSTOMER’S JULY SEWER 
BILL; 
 (2) 
THE CUSTOMER SUBMITS A WRITTEN SEWAGE DISCHARGE 
VOLUME ADJUSTMENT REQUEST ON A FORM AVAILABLE FROM THE 
DEPARTMENT AND THAT REQUEST IS RECEIVED BY THE DEPARTMENT 
NO LATER THAN 60 DAYS FROM THE DATE OF THE CUSTOMER’S JULY 
SEWER BILL; AND 
 (3) 
THE CUSTOMER SUBMITS DOCUMENTATION OR INFORMATION 
WITH ITS REQUEST THAT THE DEPARTMENT MAY RELY ON TO VERIFY 
THE CUSTOMER EXPERIENCED THE EVENTS OR CIRCUMSTANCES 
REPORTED AND THOSE WARRANT A DECREASE IN THE SEWAGE 
DISCHARGE VOLUME USED TO CALCULATE THE CUSTOMER’S ANNUAL 
SEWER CHARGE. 
(e)    THE DEPARTMENT’S WRITTEN DECISION ON THE REQUEST FOR A 
SEWAGE VOLUME DISCHARGE ADJUSTMENT IS A DETERMINATION ON A 
DISPUTED CHARGE UNDER PHOENIX CITY CODE SECTION 37-95(A), WHICH 
THE CUSTOMER MAY REQUEST ADMINISTRATIVE REVIEW OF PURSUANT TO 
SECTIONS 37-95(B) and (C).If within sixty days of a new sewer charge being 
established, a customer files a written complaint with the Director alleging that a 
significant portion of his water use does not enter the sewer system, the Director, in 
accordance with written appeals procedure, will provide an opportunity for the customer 
to present his supporting documentation to an employee designated by the Director to 
hear complaints. 
(f)    The Director shall have the authority to investigate and evaluate customer 
complaints and appeals from billing decisions of his subordinates and may correct such 
billing to reflect what in his opinion the correct billing should be, where he finds that a 
meter has been misread or some other obvious billing error has occurred. If the Director 
determines that a significant amount of water was used during the winter months for 
lawns, shrubbery or other non-sewer purposes, he shall have the authority to make a 
corresponding reduction in the sewer billing on subsequent billings only. 
Sec. 28-36. Determination of wastewater quality. 
(a)    The Director or his designee shall have the authority toMAY make whatever tests 
are necessary to carry out a planned sampling program and to make whatever analyses 
are needed for all commercial and industrial users. The BOD test shall beIS considered

53 
 
the standard test; however, COD or TOC tests may be substituted in cases where it has 
been determined by the Director DETERMINES that the BOD test is not representative 
of actual wastewater loading. Wastewater characteristics shall beARE determined by 
the Department on the basis of monitored wastewater discharged, a certified statement 
from the user, or on the best available data as to the characteristics of such discharges. 
(b)    Any change in the ongoing process(es) employed by a user contributing 
commercial or industrial waste whichTHAT results in a variation of more than twenty-
five25 percent in one or more of the effluent loading concentrations shallMUST be 
reported BY THE USER to the DepartmentDIRECTOR within thirty30 days of 
saidIMPLEMENTING THAT change. 
(c)    If it is determinedTHE DIRECTOR DETERMINES through testing that a significant 
variation exists between the user’s certified data and the discharge characteristics 
monitored by the Department, the CityDIRECTOR may adjust the sewer use charge 
based on the monitored data from the original date of certification, unless written 
communication has occurredWAS RECEIVED FROM THE USER notifying the 
DepartmentDIRECTOR of changes in loading and giving specific dates of THE 
changes. 
(d)    Designated discharge. Where sampling and gauging of specific user DISCHARGE 
is not practical for physical, economic, safety, or other reasons, the Director may 
designate values for concentrations of the wastes discharged into the sewerage system 
for all users in the same Sstandard Iindustrial Cclassification or subclassification. 
Sec. 28-37. Other user charge provisions. 
(a)    Biennial review. The Director will review, not less often than every two2 years, the 
wastewater contribution of users and user classes, the total costs of operation and 
maintenance of the treatment worksPOTW, and itsTHE DEPARTMENT’S approved 
user charge system. The Director shallMAY at such time recommend TO THE CITY 
COUNCIL a revision in the sewer service charge and user classes to accomplish the 
following: 
(1)    Maintain a reasonable proportionate distribution of operation and 
maintenance costs among users and user classes; 
(2)    Generate sufficient revenue to pay the total operation and maintenance costs 
necessary to the proper operation and maintenance (including replacement) of the 
treatment worksPOTW; and

54 
 
(3)    Apply excess revenues collected from a class of users to the costs of 
operation and maintenance attributable to that class for the next year and adjust 
the rate accordingly. 
(b)    Notification of users. Each user will be notified, at least annually, in conjunction 
with a regular bill, of the user charge rate and that portion of the total charges 
whichTHAT are attributable to user charges. 
(c)    Inconsistent agreements. The user charge system set forth in this chapter is 
applicable to all agreements or contracts between the City and users including industrial 
users, other municipalities, STATE, or federal agencies or installations, and the terms of 
this ordinance shall takeHAVE precedence over any such agreements or contracts 
whichTHAT are inconsistent with the requirements of this ordinanceCHAPTER. 
(d)    Wastewater treatment byproducts. All revenue from the sale of treatment-related 
byproducts shallWILL be used to offset the cost of operation and maintenance OF THE 
POTW. User charges shallWILL be proportionally reduced for all users. Total annual 
revenues received from the sale of a byproduct shallWILL be credited to the treatment 
worksPOTW O&MOPERATION AND MAINTENANCE cost no later than the fiscal year 
immediately following their receipt. 
Sec. 28-38. Other sewer service charges. 
In addition to the user charges described herein, the rate schedules shallWILL be 
sufficient to cover the following costs: 
(a)    A portion of the annual debt service costs for retirement of sanitary sewer 
bonds will be charged to all customers served directly by the POTWCity’s 
wastewater collection system. The Director of Water Services Department 
shallWILL make recommendations to the City Council at least once every two2 
years as to how these costs shallSHOULD be proportioned among the users. 
Charges to recover these costs will be called "other charges." 
(b)    Adequate reserve funds to allow for reasonably expected increases in the 
cost of providing services will be charged to all customers served directly by the 
POTWCity’s wastewater collection system. The Director of the Water Services 
Department shallWILL make recommendations to the City Council as to the 
amount of reserve funds necessary and as to how these funds shallSHOULD be 
proportioned among the users. 
(c)    The costs of billing and collection and performing industrial waste 
COLLECTION AND TREATEMENT services shallWILL be charged to customers 
on an equitable basis. The Director of the Water Services Department shallWILL

55 
 
make recommendations to the City Council as to how these costs shallSHOULD 
be proportioned among the users. Charges to recover these costs will be called 
"billing and collection charges" and "industrial waste charges" respectively. 
Sec. 28-39. Sewer service rates and charges within and without the City.  
(a)    There shallWILL be charged the following monthly service rate or charge for

notification shall also contain the following information to the extent such 
information is known and readily available to the industrial user: an identification of 
the hazardous constituents contained in the wastes, an estimation of the mass and

kilograms of hazardous wastes, unless the wastes are acute hazardous 
wastes as specified in 40 Code of Federal Regulations sections 261.30(d) and 
261.33(e). Discharge of more than fifteen kilograms of non-acute hazardous 
wastes in a calendar month, or of any quantity of acute hazardous wastes as 
specified in 40 Code of Federal Regulations sections 261.30(d) and 261.33(c), 
requires a one-time notification.

ALL PERMIT APPLICATIONS SUBMITTED TO THE DIRECTOR MUST CONTAIN 
THE CERTIFICATION STATEMENT IN SECTION 28-44(C)(1) SIGNED BY AN 
AUTHORIZED PERSON PER SECTION 28-44.1. 
Sec. 28-45.1. Special discharges. 
(a)    In addition to all other requirements imposed by this chapter upon industrial users, 
the following types of industrial users who are not significant industrial users may be 
required to obtain a Class B wastewater discharge permit if the Director determines the

84 
 
industrial discharge causes or has the reasonable potential to cause harm or damage to 
the POTW, worker safety, public safety or the environment: 
(1)    Zero process discharge user. 
(2)    Users which discharge the equivalent strength of twenty-five thousand 
gallons per day of domestic waste as measured by BOD and SS.

THE DIRECTOR, MUST OBTAIN A CLASS A WASTEWATER DISCHARGE PERMIT 
AND PROVIDE THE PRETREATMENT NECESSARY TO COMPLY WITH THE 
PRETREATMENT STANDARDS, PRETREATMENT REQUIREMENTS, AND BEST 
MANAGEMENT PRACTICES IMPOSED BY THIS CHAPTER. 
 
(b) 
INDUSTRIAL USERS WHO ARE NOT SIGNIFICANT INDUSTRIAL USERS 
MAY BE REQUIRED TO OBTAIN A CLASS B WASTEWATER DISCHARGE PERMIT 
IF THE DIRECTOR DETERMINES THE INDUSTRIAL DISCHARGE CAUSES OR HAS 
THE REASONABLE POTENTIAL TO CAUSE HARM OR DAMAGE TO THE POTW, 
WORKER SAFETY, PUBLIC SAFETY, OR THE ENVIRONMENT. INDUSTRIAL 
USERS WHO MAY BE REQUIRED TO OBTAIN A CLASS B WASTEWATER 
DISCHARGE PERMIT INCLUDE:    
 
(1) USERS THAT DISCHARGE THE EQUIVALENT STRENGTH OF 25,000 
GALLONS PER DAY OF DOMESTIC WASTE AS MEASURED BY BOD AND

FINDING THAT THAT THE INDUSTRIAL USER NEVER DISCHARGES MORE 
THAN 100 GALLONS PER DAY OF TOTAL CATEGORICAL WASTEWATER 
(EXCLUDING SANITARY, NON-CONTACT COOLING AND BOILER BLOWDOWN 
WASTEWATER, UNLESS SPECIFICALLY INCLUDED IN THE PRETREATMENT 
STANDARD). 
(1) THE INDUSTRIAL USER MUST MEET THE FOLLOWING CONDITIONS: 
(i) PRIOR TO THE DEPARTMENT’S FINDING, IT HAS CONSISTENTLY 
COMPLIED WITH ALL APPLICABLE CATEGORICAL PRETREATMENT 
STANDARDS AND REQUIREMENTS; 
(ii) ANNUALLY SUBMITS THE CERTIFICATION STATEMENT REQUIRED IN 
SECTION 28-44.1(c)(2) TOGETHER WITH ANY ADDITIONAL

WASTEWATER. 
(2) UPON A FINDING THAT A USER MEETING THE CRITERIA HAS NO 
REASONABLE POTENTIAL FOR ADVERSELY AFFECTING THE POTW’S 
OPERATION OR FOR VIOLATING ANY PRETREATMENT STANDARD OR 
REQUIREMENT, THE DEPARTMENT MAY AT ANY TIME, ON ITS OWN 
INITIATIVE OR IN RESPONSE TO A PETITION RECEIVED FROM AN 
INDUSTRIAL USER, AND IN ACCORDANCE WITH PROCEDURES IN 40 CFR 
403.8(F)(6), DETERMINE THAT SUCH USER SHOULD NOT BE CONSIDERED 
A SIGNIFICANT INDUSTRIAL USER. 
(3)    UPON A DETERMINATION OF NON-SIGNIFICANT CATEGORICAL 
INDUSTRIAL STATUS, THE USER MUST SUBMIT AN APPLICATION FOR A 
CLASS C WASTEWATER DISCHARGE THAT CONTAINS THE INFORMATION 
SPECIFIED IN THE APPLICATION FORM OR SUCH OTHER INFORMATION

Sec. 28-45.2. GENERAL SIGNIFICANT INDUSTRIAL USER PERMITS. 
(a)   THE DIRECTOR MAY USE GENERAL PERMITS TO CONTROL SIGNIFICANT 
INDUSTRIAL USER DISCHARGES TO THE POTW IF ALL FACILITIES TO BE 
COVERED BY THE GENERAL PERMIT:  
(1) INVOLVE THE SAME OR SUBSTANTIALLY SIMILAR TYPES OF 
OPERATIONS;  
(2) DISCHARGE THE SAME TYPES OF WASTES;  
(3) REQUIRE THE SAME EFFLUENT LIMITATIONS;   
(4) REQUIRE THE SAME OR SIMILAR MONITORING; AND

86 
 
(5) AS DETERMINED BY THE DIRECTOR, ARE MORE APPROPRIATELY 
CONTROLLED UNDER A GENERAL PERMIT THAN UNDER INDIVIDUAL 
WASTEWATER DISCHARGE PERMITS.    
(b)    TO BE COVERED BY A GENERAL PERMIT, THE SIGNIFICANT INDUSTRIAL 
USER MUST FILE A WRITTEN REQUEST FOR COVERAGE WITH THE 
DEPARTMENT THAT IDENTIFIES: 
(1) ITS CONTACT INFORMATION; 
(2) PRODUCTION PROCESSES; 
(3) THE TYPES OF WASTES GENERATED; 
(4) THE LOCATION(S) FOR MONITORING ALL WASTES COVERED BY THE 
GENERAL PERMIT; AND  
(5) ANY OTHER INFORMATION THE DEPARTMENT DEEMS APPROPRIATE.  
(c)    THE DIRECTOR WILL RETAIN A COPY OF THE GENERAL PERMIT, 
DOCUMENTATION TO SUPPORT THE DEPARTMENT’S DETERMINATION THAT A 
SPECIFIC SIGNIFICANT INDUSTRIAL USER MEETS THE CRITERIA IN 
PARAGRAPH (A) ABOVE AND APPLICABLE STATE REGULATIONS, AND A COPY 
OF THE USER’S WRITTEN REQUEST FOR COVERAGE FOR 3 YEARS AFTER THE 
EXPIRATION OF THE GENERAL PERMIT.  
(d)     THE DIRECTOR MAY NOT CONTROL A SIGNIFICANT INDUSTRIAL USER 
THROUGH A GENERAL PERMIT WHERE THE FACILITY IS SUBJECT TO 
PRODUCTION-BASED CATEGORICAL PRETREATMENT STANDARDS OR 
CATEGORICAL PRETREATMENT STANDARDS EXPRESSED AS MASS OF 
POLLUTANT DISCHARGED PER DAY OR FOR INDUSTRIAL USERS WHOSE 
LIMITS ARE BASED ON THE COMBINED WASTE STREAM FORMULA IN 40 CFR 
403.6(E). 
Sec. 28-45.3. CATEGORICAL INDUSTRIAL USER PERMIT LIMITS. 
INDUSTRIAL USERS MUST COMPLY WITH THE CATEGORICAL PRETREATMENT 
STANDARDS FOUND AT 40 CFR PARTS 405 THROUGH 471, AND THERE MAY BE 
NO DISCHARGE OF ANY WATER OR WASTE EXCEEDING THE PRETREATMENT 
STANDARDS LIMITS AND LOCAL LIMITS IN SECTION 28-8. 
 
(a) WHEN WASTEWATER SUBJECT TO A CATEGORICAL PRETREATMENT 
STANDARD IS MIXED WITH WASTEWATER NOT REGULATED BY THE 
SAME STANDARD, THE DIRECTOR MAY IMPOSE AN ALTERNATE LIMIT ON 
THAT WASTEWATER IN ACCORDANCE WITH 40 CFR 403.6(E).   
(b) WHEN THE LIMITS IN A CATEGORICAL PRETREATMENT STANDARD ARE 
EXPRESSED ONLY IN TERMS OF MASS OF POLLUTANT PER UNIT OF 
PRODUCTION, THE DIRECTOR MAY CONVERT THE LIMITS TO 
EQUIVALENT LIMITATIONS EXPRESSED EITHER AS MASS OF POLLUTANT

87 
 
DISCHARGED PER DAY OR EFFLUENT CONCENTRATION FOR PURPOSES 
OF CALCULATING EFFLUENT LIMITATIONS APPLICABLE TO INDIVIDUAL 
INDUSTRIAL USERS. 
(c) WHEN THE LIMITS IN A CATEGORICAL PRETREATMENT STANDARD ARE 
EXPRESSED ONLY IN TERMS OF POLLUTANT CONCENTRATIONS, AN 
INDUSTRIAL USER MAY REQUEST THAT THE DEPARTMENT CONVERT 
THE LIMITS TO EQUIVALENT MASS LIMITS. THE DETERMINATION 
WHETHER TO CONVERT CONCENTRATION LIMITS TO MASS LIMITS IS 
WITHIN THE SOLE DISCRETION OF THE DIRECTOR.  TO BE ELIGIBLE FOR 
EQUIVALENT MASS LIMITS, THE INDUSTRIAL USER MUST:  
(1) EMPLOY, OR DEMONSTRATE THAT IT WILL EMPLOY, WATER 
CONSERVATION METHODS AND TECHNOLOGIES THAT 
SUBSTANTIALLY REDUCE WATER USE DURING THE TERM OF ITS 
INDIVIDUAL WASTEWATER DISCHARGE PERMIT; 
(2) CURRENTLY USE CONTROL AND TREATMENT TECHNOLOGIES 
ADEQUATE TO ACHIEVE COMPLIANCE WITH THE APPLICABLE 
CATEGORICAL PRETREATMENT STANDARD, AND NOT HAVE USED 
DILUTION AS A SUBSTITUTE FOR TREATMENT; 
(3) PROVIDE SUFFICIENT INFORMATION TO ESTABLISH THE 
FACILITY’S ACTUAL AVERAGE DAILY FLOW RATE FOR ALL WASTE 
STREAMS, BASED ON DATA FROM A CONTINUOUS EFFLUENT 
FLOW MONITORING DEVICE, AS WELL AS THE FACILITY’S LONG-
TERM AVERAGE PRODUCTION RATE; BOTH THE ACTUAL AVERAGE 
DAILY FLOW RATE AND THE LONG-TERM AVERAGE PRODUCTION 
RATE MUST BE REPRESENTATIVE OF CURRENT OPERATING 
CONDITIONS; 
(4) NOT HAVE DAILY FLOW RATES, PRODUCTION LEVELS, OR 
POLLUTANT LEVELS THAT VARY SO SIGNIFICANTLY THAT 
EQUIVALENT MASS LIMITS ARE NOT APPROPRIATE TO CONTROL 
THE DISCHARGE; AND 
(5) HAVE CONSISTENTLY COMPLIED WITH ALL APPLICABLE 
CATEGORICAL PRETREATMENT STANDARDS PRIOR TO THE 
INDUSTRIAL USER’S REQUEST FOR EQUIVALENT MASS LIMITS.   
(d) AN INDUSTRIAL USER SUBJECT TO EQUIVALENT MASS LIMITS MUST:  
(1) MAINTAIN AND EFFECTIVELY OPERATE CONTROL AND 
TREATMENT TECHNOLOGIES ADEQUATE TO ACHIEVE 
COMPLIANCE WITH THE EQUIVALENT MASS LIMITS;  
(2) CONTINUE TO RECORD THE FACILITY’S FLOW RATES THROUGH 
THE USE OF A CONTINUOUS EFFLUENT FLOW MONITORING 
DEVICE;

88 
 
(3) CONTINUE TO RECORD THE FACILITY’S PRODUCTION RATES AND 
NOTIFY THE DIRECTOR WHENEVER PRODUCTION RATES ARE 
EXPECTED TO VARY BY MORE THAN 20 PERCENT FROM ITS 
BASELINE PRODUCTION RATES DETERMINED IN SECTION 28-
45.3(c)(3); UPON NOTIFICATION OF A REVISED PRODUCTION RATE, 
THE DIRECTOR WILL REASSESS THE EQUIVALENT MASS LIMIT 
AND REVISE THE LIMIT AS NECESSARY TO REFLECT CHANGED 
CONDITIONS AT THE FACILITY; AND  
(4) CONTINUE TO EMPLOY THE SAME OR COMPARABLE WATER 
CONSERVATION METHODS AND TECHNOLOGIES AS THOSE 
IMPLEMENTED PURSUANT TO SECTION 28- 45.3(a) SO LONG AS IT 
DISCHARGES UNDER AN EQUIVALENT MASS LIMIT. 
(e) WHEN DEVELOPING EQUIVALENT MASS LIMITS, THE DIRECTOR: 
(1) WILL CALCULATE THE EQUIVALENT MASS LIMIT BY MULTIPLYING 
THE ACTUAL AVERAGE DAILY FLOW RATE OF THE REGULATED 
PROCESS(ES) OF THE INDUSTRIAL USER BY THE 
CONCENTRATION-BASED DAILY MAXIMUM AND MONTHLY 
AVERAGE STANDARD FOR THE APPLICABLE CATEGORICAL 
PRETREATMENT STANDARD AND THE APPROPRIATE UNIT 
CONVERSION FACTOR; 
 
(2) UPON NOTIFICATION OF A REVISED PRODUCTION RATE, WILL 
REASSESS THE EQUIVALENT MASS LIMIT AND RECALCULATE THE 
LIMIT AS NECESSARY TO REFLECT CHANGED CONDITIONS AT THE 
FACILITY; AND  
(3) MAY RETAIN THE SAME EQUIVALENT MASS LIMIT IN SUBSEQUENT 
INDIVIDUAL WASTEWATER DISCHARGE PERMIT TERMS IF THE 
INDUSTRIAL USER’S ACTUAL AVERAGE DAILY FLOW RATE WAS 
REDUCED SOLELY AS A RESULT OF THE IMPLEMENTATION OF 
WATER CONSERVATION METHODS AND TECHNOLOGIES, AND THE 
ACTUAL AVERAGE DAILY FLOW RATES USED IN THE ORIGINAL 
CALCULATION OF THE EQUIVALENT MASS LIMIT WAS NOT BASED 
ON THE USE OF DILUTION AS A SUBSTITUTE FOR TREATMENT 
PURSUANT TO SECTION 28-8(g); THE INDUSTRIAL USER MUST 
ALSO BE IN COMPLIANCE WITH SECTION 28-11.1 REGARDING THE 
PROHIBITION OF BYPASS.  
(f) THE DIRECTOR MAY CONVERT THE MASS LIMITS OF THE CATEGORICAL 
PRETREATMENT STANDARDS OF 40 CFR PARTS 414, 419, AND 455 TO 
CONCENTRATION LIMITS FOR PURPOSES OF CALCULATING LIMITATIONS 
APPLICABLE TO INDIVIDUAL INDUSTRIAL USERS.  THE CONVERSION IS 
AT THE SOLE DISCRETION OF THE DIRECTOR. 
(g) ONCE INCLUDED IN ITS PERMIT, THE INDUSTRIAL USER MUST COMPLY 
WITH THE EQUIVALENT LIMITATIONS DEVELOPED IN THIS SECTION IN

89 
 
LIEU OF THE PROMULGATED CATEGORICAL PRETREATMENT 
STANDARDS FROM WHICH THE EQUIVALENT LIMITATIONS WERE 
DERIVED.  
(h) MANY CATEGORICAL PRETREATMENT STANDARDS SPECIFY ONE LIMIT 
FOR CALCULATING MAXIMUM DAILY DISCHARGE LIMITATIONS AND A 
SECOND LIMIT FOR CALCULATING MAXIMUM MONTHLY AVERAGE, OR 
FOUR-DAY AVERAGE, LIMITATIONS. WHERE SUCH STANDARDS ARE 
BEING APPLIED, THE SAME PRODUCTION OR FLOW FIGURE WILL BE 
USED TO CALCULATE BOTH THE AVERAGE AND THE MAXIMUM 
EQUIVALENT LIMITATION.  
(i) ANY INDUSTRIAL USER OPERATING UNDER A PERMIT INCORPORATING 
EQUIVALENT MASS OR CONCENTRATION LIMITS CALCULATED FROM A 
PRODUCTION-BASED STANDARD MUST NOTIFY THE DIRECTOR WITHIN 
TWO BUSINESS DAYS AFTER THE USER HAS A REASONABLE BASIS TO 
KNOW THAT THE PRODUCTION LEVEL WILL SIGNIFICANTLY CHANGE 
WITHIN THE NEXT CALENDAR MONTH. ANY USER THAT FAILS TO NOTIFY 
THE DIRECTOR OF SUCH ANTICIPATED CHANGE WILL BE REQUIRED TO 
MEET THE MASS OR CONCENTRATION LIMITS IN ITS PERMIT THAT WERE 
BASED ON THE ORIGINAL ESTIMATE OF THE LONG-TERM AVERAGE 
PRODUCTION RATE.

106 
 
For the purposes of this article only, the following words and phrases, shall have the 
meanings specified in this section, unless from the content, a different meaning is 
clearly intended. 
Advanced sewage treatment means additional treatment needed to remove suspended 
and dissolved substances not normally removed during secondary treatment including 
organic matter; suspended solids; inorganic ions such as calcium, phosphate, nitrate, 
and potassium; as well as synthetic organic compounds. 
Air contaminant/odor control means a process whichTHAT neutralizes air contaminants 
and odors emanating from sewage caused by the decomposition of organic matter in 
raw sewage and reduces such air contaminants or odors to the appropriate air 
discharge limitations. 
Air stripping means a process utilized for the removal of ammonia whichTHAT may be 
toxic to aquatic life, or for the removal of volatile organic compounds (VOCs), some of 
which are carcinogenic. 
Biological nutrient removal (nitrification-denitrification) means a process by which the 
nitrogen content of sewage treatment plant effluent is decreased in order to reduce the 
growth of algae and aquatic plants in receiving waters. This process also lowers the 
content of ammonia, which is toxic to aquatic life, in treated sewage effluent. 
Dechlorination means the process by which chlorine, which may be toxic to aquatic life, 
is removed from the treated sewage treatment plant effluent following disinfection. 
Granular activated carbon treatment means a process in which non-volatile and semi-
volatile organic compounds are removed through adsorption on the surface of carbon 
particles. 
Secondary sewage treatment means treatment by which dissolved or suspended 
materials are converted through biological action and sedimentation to a form 
whichTHAT allows more ready separation and results in a sewage treatment plant 
effluent whichTHAT can be characterized by the following average constituent 
concentrations: (a) BOD: thirty milligrams per liter, (b) TSSsuspended solids: thirty 
milligrams per liter, and (c) ph: 6.0 to 9.0 
Water quality programs means programs required by the National Pollutant Discharge 
Elimination System (NPDES) permit OR AZPDES PERMIT for industrial pretreatment 
enforcement and monitoring, customer education, and plant laboratory analysis and 
monitoring.

107 
 
Water reclamation means a process or series of processes by which suspended and 
dissolved solids remaining following secondary or advanced treatment are removed to a 
level which allows the sewage treatment plant effluent to be used beneficially. This may 
include flocculation, coagulation and filtration.
