SECTION 17. INDUSTRIAL COST RECOVERY (A) The City will request all significant waste dischargers who are contributing to any sanitary sewer system affected by improvements to that system which are constructed with Federal assistance under PL 92-500 to sign a letter of intent to pay that portion of the Federal grant amount allocable to its industrial waste discharge. Such significant waste dischargers shall submit their signed letters of intent within thirty ( 30) days after receipt of the City's request for such letter. Such letter of intent shall also include a statement of the period of the industrial user's intended use of the proposed improvements. (B) An industrial user may make a written request for reserve capacity for anticipated increases in either volume or strength. If the Approving Authority determines that such capacity can be reserved, he will so notify the industrial user in writing within thirty (30) days after receipt of request. If such reserve capacity is granted by the City, this value will be used in the following formula to ascertain the industrial user's annual share. Such reservations are valid unless (1 ) the industrial user notifies the City in writing that it no longer desires such reservation or capacity, or (2) the industrial user fails or refuses to make annual payment for reservation of such capacity, and in either of these events the industrial user is not entitled to any refund of payments made for such reserved capacity. (C) All industrial users discharging industrial waste to the sanitary sewer system affected by improvements for which the City received a Federal grant under PL 92-500 shall make annual payments to the City during the industrial cost recovery period, paying its individual share of the grant amount received by the City divided by the industrial cost recovery period. Each industrial user's annual share shall be calculated from the following formula, and the values for volume, BOD and SS shall be the same as its values used by the City during the previous year for calculation of user charges to industrial users: (1 ) Sanitary Sewer Lines and Pump Stations: A �30 � (B) �C E D) �30) (C B D) A = Annual payment by industrial user.

If an industrial user has been discharging to the sanitary sewer system affected by the improvements less than one year prior to the date of the billing, the bill will be calculated on a monthly basis for the period of time the industrial user has been discharging to said sanitary sewer system. Payments for the industrial users will be due within forty-five (45) days of the billing date. (E) The City may terminate wastewater industrial user services from the system when: (1 ) Any significant waste discharger fails to submit the required letter of intent required by Paragraph (A) of this section within forty-five (45) days after written notice from the City that same is required is received. (2) Any industrial user fails to make annual payments as required by this section within forty-five (45) days after receipt of bill from the City. (F) Annual payments made hereunder are not in lieu of any sanitary sewer connection charges established by other City regulations, or user charges established by this regulation. SECTION 18. USER CHARGES (A) The user charges to be determined for all permitted manufacturing or other producers of waste to which this regulation applies, except for those producing a domestic waste only, will be computed by the use of the following formula: UC = V C + Y (BOD) + Z (SS) J �J Formula Values are: UC = User charge (in dollars). V = Volume in millions of gallons discharged to the City sewer system during the billing period. X = Cost per million gallons of wastewater treated. Y = Cost to remove one (1 ) mg/1 of BOD per million gallons. Z = Cost to remove one (1 ) mg/1 of suspended solids per million gallons. BOD = Five (5) day, twenty (20) degree Centigrade biochemical oxygen demand content of the waste delivered in mg/1 . SS = Suspended solids content of the waste delivered in mg/1 . (B) Those industries defined herein as dry industries, or industries producing wastes containing both BOD and suspended solids of less than three hundred (300) mg/l , will pay a sewer service charge at the uniform rate of forty-eight cents (48�) or 10% greater than the residential charge whichever is higher. (C) When either BOD or suspended solids in a delivered waste is more than three hundred (300) mg/1 , this formula will be used, but in no event will either be used at less than three hundred (300) mg/1 in the computations. (D) When an industry produces both domestic and process waste with one connection to the sewer system, the waste so delivered will be considered as industrial waste with uniform rate; or by user charge computations, in com- pliance with the above, based on the combined volume, BOD and suspended solids content. -12B- (E) A permittee may reduce his user charge rate by greater removals in pretreatment or plant operation procedure, but once the pretreatment or plant procedure is established to obtain uniform or lower rate, written consent from the General Manager to increase the delivered strength shall be required and charges for a higher rate based on tests by the City may be made without other notice to the permittees. (F) Monthly billing or bimonthly billing for industrial waste disposal will be accomplished, using the established procedures. SECTION 19. ADJUSTMENT OF CHARGES. (A) The City shall adjust charges at least annually to reflect changes in the characteristics of wastewater based on the results of sampling and testing. (B) Increases in charges shall be retroactive for two billing periods and shall continue for six (6) billing periods unless subsequent tests determine that the charge should be further increased. (C) The City shall review at least semi-annually the basis for determining charges and shall adjust the unit treatment cost in the formula to reflect increases or decreases in wastewater treatment costs based on the previous year's experience. (D) The City shall bill the discharger by the month and shall show industrial waste charges as a separate item on the regular bill for water and sewer charges. The discharger sha-1 pay monthly in accordance with practices existing for payment of sewer charges. SECTION 20. SAVINGS CLAUSE. A person discharging industrial wastes into public sewers prior to the effective date of this ordinance may continue without penalty so long as he (1 ) does not increase the quantity or quality of discharge, without permission of the Approving Authority; (2) has discharged the industrial waste at least 12 months prior to the effective date of this ordinance. (3) applies for and is granted a permit no later than 150 days after the effective date of this ordinance. SECTION 21 .
